    [001] [001] The invention relates to the field of optical distribution networks, in particular, a connector, an adapter, and a fiber optic connection assembly with quick plug. Fundamentals of the Invention
    [002] [002] With the large-scale implementation of Fiber to Residence (FTTH), fiber optic connection assembly is increasingly used. In general, the fiber optic connection assembly comprises a fiber optic connector and adapter. Most fiber optic connectors and adapters used at this stage are industry standard connectors and adapters. The original design of this type of connectors and adapters is to resolve the fiber connection in the room or in a protective box. Therefore, the following defects exist in actual use:
    [003] [003] Currently, there are a small number of waterproof fiber optic connectors and adapters on the market, but most locking methods are screw type. However, due to its own characteristics, the screw-type locking method has the disadvantages of complicated plugging and unplugging operations (insertion and removal operations) and limited locking force.
    [004] [004] Therefore, how to solve the problems of inconvenient plugging and unplugging operations and insufficient locking force in the assembly of the existing fiber optic connection, as well as the problems of waterproof and dustproof devices, are urgent problems for those skilled in the art. Summary of the Invention
    [005] [005] In view of the defects existing in the previous technology, an objective of the present invention is to provide a fiber optic connection assembly with quick plug, which solves the problem of low withdrawal force.
    [006] [006] In order to achieve the above objective, the technical solution adopted by the present invention is: a connector for fiber optic connection, in which the connector comprises a body of the plug, and in which a jacket of the plug is provided on the outside of the the plug body, the front end of the plug jacket is provided with an ejection device, and the outer surface of the plug body is provided with a groove to clamp an adapter corresponding to the connector.
    [007] [007] Because the intensity of the groove is greater than that of the thread, greater withdrawal force can be supported through the groove.
    [008] [008] Based on the exposed technical solution, the ejection device is configured to eject the internal adapter sleeve corresponding to the connector, to change the state of the adapter to connect with the connector.
    [009] [009] Based on the exposed technical solution, the ejection device is an ejection block formed by the extension of the outer surface of the plug body, or the ejection device is an ejection piece arranged at a distance from the body surface the plug.
    [0010] [0010] Different structures of the ejection device need to be adapted to different internal sleeves, as long as the ejection device can finally make the inner sleeve move in the axial direction of the adapter.
    [0011] [0011] Based on the exposed technical solution, the plug body comprises: a part of the main body, which is provided with a cavity; an insertion part, which is located at one end of the main body part; wherein a ferrule fixing part is provided at one end of the remote insertion part of the main body part, the ferrule fixing part is fixed with a fiber optic ceramic ferrule, and the groove is located on the outer surface of the part insertion. Instead of providing a thread on the outer periphery of the plug jacket as in the previous technology, the functional structure for connection is provided on the insertion part to reduce the diameter of the adapter.
    [0012] [0012] Based on the exposed technical solution, the groove is located on the external surface of the area where the insertion part is provided with the ferrule fixation part.
    [0013] [0013] Because the ferrule fixation part has a greater wall thickness, and after the optical fiber ceramic ferrule is installed in the ferrule fixation part, its intensity is greater. The groove is defined here to withstand even greater radial force, which further improves the ability to withstand the withdrawal force.
    [0014] [0014] Based on the exposed technical solution, the plug sleeve is formed by the extension of the main body part towards the insertion part, and the ejection device is the ejection piece formed by the extension of the plug sleeve end, and the ejection part is spaced from the insertion part. Because the ejection part is spaced from the insertion part, the ejection part can resist the inner sleeve and extend between the outer sleeve of the adapter and the border, so that the adapter is clipped onto the connector.
    [0015] [0015] Based on the exposed technical solution, the groove is an annular groove arranged along the circumferential direction of the plug body, or the groove is a hemispherical groove.
    [0016] [0016] There are advantages to using an annular groove or a hemispherical groove. The annular groove does not require very strict deflection angle alignment. In contrast, the hemispherical groove requires more precise deflection angle alignment, otherwise it will make it difficult for the adapter's clamping body to be precisely clamped in the central position of the hemispherical groove. However, because the hemispherical groove can often be more corresponding to the shape of the clamping body, this can provide a better clamping effect, thereby improving the ability to withstand the withdrawal force.
    [0017] [0017] The present invention also provides a connector for fiber optic connection, wherein the connector comprises: a part of the main body, which is provided with a cavity; an optical cable, mounted on the main body part, and the optical cable extends into the cavity; an insertion part, located at one end of the main body part; wherein a ceramic fiber optic ferrule is provided at one end of the remote insertion part of the main body part, and the insertion part is provided with a groove to clamp an adapter corresponding to the connector; and at the same time, an ejection device, provided on the periphery of the insertion part, and the ejection device is configured to eject the internal adapter sleeve corresponding to the connector.
    [0018] [0018] Because the general intensity of the groove is greater than that of the thread, clamping through the groove can withstand even greater withdrawal force, and the ejection device is provided at the periphery of the insertion part to trigger the connection and the adapter latch.
    [0019] [0019] Based on the exposed technical solution, the ejection device is an ejection block provided on the external surface of the insertion part, or the ejection device is an ejection piece spaced from the external surface of the insertion part.
    [0020] [0020] Based on the exposed technical solution, the groove is located on the external surface of the area where the ceramic fiber optic ferrule is installed in the insertion part.
    [0021] [0021] The present invention also provides an adapter for fiber optic connection, wherein the adapter comprises: an adapter body, where at least one end of the adapter body is a cylindrical boundary part, the boundary part is provided with a bordering channel, the adapter body is provided with a ferrule receiving seat for receiving a ceramic fiber optic ferrule, and the bordering part is provided with a receiving groove that communicates with the bordering channel; a clamping body, which is movably received in the receiving slot; an external glove, movable gloved outside the boundary part; wherein the outer sleeve has a first state and a second state; and, when the outer sleeve is in the first state, the outer sleeve resists the clamping body, and causes the clamping body part to insert into the border channel in an irreversible manner; when the outer sleeve is in the second state, a space reserved for the clamping body to exit the boundary channel is provided between the outer sleeve and the opening of the receiving slot; the inner sleeve, movably mounted on the border, and the inner sleeve is configured to keep the outer sleeve in the first state after being pushed upward in the direction of insertion.
    [0022] [0022] Because, when the outer sleeve is in the first state, part of the clamping body irreversibly insert in the border channel, and the part that inserts in the border channel is configured to cooperate with the slot of the connector, to connect and lock the connector and adapter, and because the clamping body is resisted and cannot be removed, its boundary channel makes the connection between the connector and the adapter very strong and can withstand very high tension forces.
    [0023] [0023] Based on the exposed technical solution, the clamping body is a steel ball, the receiving groove is a cylindrical hole, and a stop part is provided at the base of the receiving groove to prevent the steel ball from falling out of the receiving slot completely. The steel ball is selected as the clamping body because the steel ball itself is of high intensity and it is not easy to stand still when it moves up and down in the receiving groove.
    [0024] [0024] Based on the exposed technical solution, the outer sleeve is provided with a resistance block that protrudes from the inner wall, and, when the outer sleeve is in the first state, the resistance block is located in the receiving groove and resists the clamping body. By providing a resistance block on the inner wall of the outer sleeve, there is a space reserved for the clamping body in other areas, except the resistance block. The clamping body will not be resisted and contained, except in the first state, and the clamping body can also be completely returned to the receiving groove.
    [0025] [0025] Based on the exposed technical solution, the side of the resistance block near the receiving seat of the ferrule has an inclined surface. When the first state is switched to the second state, the inclined surface can guide the clamping body downwards, so that the switching between the first state and the second state is more uniform.
    [0026] [0026] Based on the exposed technical solution, the bordering part comprises a first section close to the ferrule receiving seat and a second section further extended from the first section, and the radius of the first section is greater than that of the second section ; one end of the outer sleeve near the ferrule receiving seat is gloved in the first section, and, during switching between the first state and the second state, the resistance block moves axially in the second section. The difference in the diameter formed between the first section and the second section is to create a space for the resistance block to move, and to reduce the diameter of the outer sleeve, thereby reducing the diameter of the integral of the adapter.
    [0027] [0027] Based on the exposed technical solution, the faces of the rear end of the inner sleeve are respectively resisted to the outer sleeve by an external spring, and, when the outer sleeve is in the first state, the inner sleeve keeps the outer sleeve in the first through the external spring.
    [0028] [0028] The outer spring is configured to propel the outer sleeve forward when the inner sleeve is propelled by the ejection device until the clamping body is stopped in the groove. At this point, the outer spring keeps the outer sleeve in its original position, so that the resistance block resists the clamping body.
    [0029] [0029] Based on the exposed technical solution, an axially arranged inner spring is provided between the inner sleeve and the border. The inner spring is provided so that the connector and adapter can automatically eject when the outer sleeve is manually pulled back.
    [0030] [0030] Based on the exposed technical solution, the elastic force of the external spring is greater than the elastic force of the internal spring. The elastic force of the outer spring is greater than the elastic force of the inner spring, which enables the inner spring to drive the connector and no excessive elastic force is required, thereby preventing excessive mutual thrust between the connector and the adapter in the connected state, which can reduce the stability of the connection.
    [0031] [0031] Based on the exposed technical solution, the inner glove is combined between the outer glove and the boundary part, and the inner glove, the outer glove and the boundary part can slide in relation to each other.
    [0032] [0032] Based on the exposed technical solution, a retaining ring is provided at the end of the surface of the outer sleeve and the border facing the inner sleeve. The retaining ring prevents the inner sleeve from being pushed out of the outer sleeve by the inner spring and the outer spring.
    [0033] [0033] Based on the expostay technical solution, the clamping body comprises an elastic arm extending from the border, and a clamping block is provided at the end of the elastic arm; and at the same time, when the outer sleeve is in the first state, the elastic arm is in a state of undirected elastic deformation, and the clamping block is completely received in the receiving groove; when the outer sleeve is in the first state, the outer sleeve resists in the clamping block, and the clamping block extends partially into the boundary channel.
    [0034] [0034] Compared to the clamping method using steel balls, the method in which the clamping block is provided at the end of the elastic arm can automatically cause the clamping block to exit the boundary channel when the outer sleeve is retracted for the second state.
    [0035] [0035] The present invention also provides a fiber optic connection assembly with quick plug, which comprises an adapter and a connector; where the adapter comprises:
    [0036] [0036] Compared with the locking force of the locking device (buckle) used by the existing standard connector, the locking force of the connection method using the clamping body and the groove is even greater. The connection method using the clamping body and the groove is best suited for complex outdoor scenarios and can withstand even greater withdrawal force. In addition, the insertion force required during insertion is small, and the locking force is large when locked. When pulled out, the connector can be evenly pulled out, and the withdrawal force is small, which has the characteristic of convenient operation, and can effectively solve the problems of inconvenient plugging and unplugging operations and insufficient locking force. in the existing fiber optic connection assembly.
    [0037] [0037] The present invention also provides a fiber optic connection assembly with a quick plug, comprising an adapter and a connector, wherein the adapter comprises an adapter body capable of forming a top joint with the connector at both ends; either end of the adapter body is provided with a locking structure, and the locking structure comprises a directional boundary groove provided on the wall on the inside of the adapter body, a steel ball embedded in the wall on the outside of the adapter body , an external gloved sleeve outside the adapter body and pressed against the steel ball, and an internal sleeve provided between the adapter body and the outer sleeve; wherein a plurality of the directional boundary grooves are uniformly distributed along the circumferential direction of the adapter body; the faces of the rear end of the inner sleeve resist in the outer sleeve and in the adapter body, respectively, through an outer spring and an inner spring, and the elastic force of the outer spring is greater than the elastic force of the inner spring; the front end faces of the inner sleeve are respectively resisted by the outer sleeve and the adapter body; the outer sleeve, the adapter body and the inner sleeve can slide in relation to each other; and the wall on the inner side of the outer sleeve has an inclined surface to press the steel ball into the connector to lock the connector; the connector comprises a plug body, the outer surface of the plug body being provided with a directional boundary projection adapted to the directional boundary groove; the exterior of the plug body is provided with a plug sleeve, and the front end of the plug sleeve is provided with an ejection device to eject the inner sleeve; and the outer surface of the plug body is provided with an annular groove corresponding to the steel ball along its circumferential direction; when the steel ball is pressed into the annular and clamped groove, the adapter can be locked with the connector.
    [0038] [0038] Based on the exposed technical solution, the contact surface of the connector plug body and the adapter body is flush with at least one O-shaped seal ring.
    [0039] [0039] Based on the exposed technical solution, two O-shaped sealing rings are provided.
    [0040] [0040] Based on the exposed technical solution, when the adapter is installed in an installation interface, the contact surface of the adapter body and the installation interface is provided with a flat sealing washer.
    [0041] [0041] Based on the exposed technical solution, the O-shaped sealing ring and the flat sealing washer are made of rubber or silicone.
    [0042] [0042] Based on the exposed technical solution, when the adapter is not a butt joint with the connector, a protective plug is inserted into the adapter, and the protective plug is provided with an ejection device, an annular groove and an annulus. O-shaped seal with the same structures provided in the connector.

    [0045] [0045] Based on the exposed technical solution, the other end of the adapter body is not provided with a locking structure, and is configured to make the butt joint with the existing standard connector.
    [0046] [0046] Based on the exposed technical solution, there are three directional limit grooves evenly distributed along the circumferential direction of the adapter body.

    [0053] [0053] The present invention will be further described in detail below with respect to the drawings and the specific modalities.
    [0054] [0054] See figures 1 to 19 at the same time, where the modality of the present invention provides a connector 2 for fiber optic connection. The connector 2 comprises a body of the plug 201, which is configured to carry the optical cable 215 and for hand operation. A plug sleeve 205 is provided outside the plug body 201, and the front end of the plug sleeve 205 is provided with an ejection device 206; the outer surface of the plug body 201 is provided with a groove to clamp an adapter corresponding to the connector. The groove can be an annular groove 207. Compared with the prior art threaded connection method, the use of the groove as the connection structure can withstand greater withdrawal force, does not require rotation, and can be directly inserted, which is convenient to operate. Furthermore, since no rotation is required, the space for manual operation is small, which can increase the density of the connector on the panel.
    [0055] [0055] See figures 1 to 19 at the same time, as an optional modality, in which the difference between this modality and Modality 1 is that the ejection device 206 is configured to eject the internal sleeve 106 of the adapter | corresponding to connector 2, to change the state of adapter 1, and thereby make adapter 1 connect with the connector. Of course, the ejection device 206 can also eject other similar structures from adapter 1, provided that the state of adapter 1 can be changed and the effect of the connection can be achieved.
    [0056] [0056] See figures 1 to 19 at the same time, as an optional modality, in which the difference between this modality and the Modality | is that the ejection device 206 is an ejection block formed by the extension of the outer surface of the plug body 201. If the ejection device 206 adopts this structure, the inner sleeve 106 corresponding to the ejection device 206 can be provided with a projection (not shown in the figures) protruding from the outer sleeve 205, so that the ejection device 206 can propel the inner sleeve 106 and cause the inner sleeve 106 to move axially with respect to the outer sleeve 205.
    [0057] [0057] See figures 1 to 19 at the same time, as an optional modality, in which the difference between this modality and Modality 1 is that the ejection device 206 is an ejection piece arranged at a distance from the surface of the plug body 201. The ejection part can be directly inserted into the outer sleeve 205, so that the ejection device 206 can propel the inner sleeve 106 and cause the inner sleeve 106 to move axially with respect to the outer sleeve 205.
    [0058] [0058] In summary, different structures of the ejection device 206 need to be adapted to different inner sleeves 106, provided that the ejection device 206 can finally drive the inner sleeve 106 and make the inner sleeve 106 move axially with respect to the external sleeve 205.
    [0059] [0059] See figures 1 to 19 at the same time, specifically, the difference between this modality and the Modality | is that the body of the plug
    [0060] [0060] Additionally, the groove is located on the outer surface of the area where the insertion part 201c is provided with the ferrule fixing part 201d.
    [0061] [0061] Because the ferrule 201d fixation part has a greater wall thickness, and, after the 203 fiber optic ceramic ferrule is installed in the ferrule fixation part, its intensity is greater. After connector 2 is connected to adapter 1, the groove will be subjected to radial force when connector 2 is pulled. The groove is defined here to withstand an even greater radial force, which further improves the ability to withstand the withdrawal force.
    [0062] [0062] Specifically, the plug sleeve 205 is formed by the extension of the main body part 201a towards the insertion part 201c, and the ejection device 206 is the ejection piece formed by the extension of the plug sleeve end 205, and the ejection part is spaced from insertion part 201c. Since the ejection part is disposed at a distance from the insertion part 201c, the ejection part can resist the inner sleeve 106 and extend between the outer sleeve 105 of the adapter and the boundary part 40, so that the adapter be clipped to the connector.
    [0063] [0063] Optionally, the groove is an annular groove 207 arranged along the circumferential direction of the body of the plug 201, or the groove is a hemispherical groove.
    [0064] [0064] There are advantages to using a 207 ring slot or a hemispherical slot. The annular groove 207 does not require very strict deflection angle alignment. On the contrary, the hemisphere groove requires a more precise deflection angle alignment, otherwise it will make it difficult for the clamping body of adapter 1 to be precisely clamped in the central position of the hemispherical groove. However, because the hemispherical groove can often be more corresponding to the shape of the clamping body, which can provide a better clamping effect, thereby improving the ability to withstand the withdrawal force. In this embodiment, in order to facilitate processing, and because the annular groove 207 can already withstand a very high withdrawal force, the annular groove 207 is preferably selected in the embodiment of the present invention.
    [0065] [0065] See figures 1 to 19 at the same time, where the present invention also provides a connector for fiber optic connection, comprising: a part of the main body 201a, which is provided with a cavity 201b; an optical cable 215, mounted on the main body part 201a, and the optical cable 215 extends into the cavity 201b; an insertion part 201c, located at one end of the main body part 201a, and an end of the remote insertion part 201lc of the main body part 201a is provided with a fiber optic ceramic ferrule 203. The insertion part 201c is provided with a groove to clamp an adapter corresponding to the connector; and at the same time, an ejection device 206 is provided at the periphery of the insertion part 201c. The ejection device 206 is configured to eject the inner sleeve 106 of the adapter corresponding to the connector.
    [0066] [0066] Because the overall intensity of the groove is greater than that of the thread, clamping through the groove can withstand greater withdrawal force, and the ejection device 206 is provided at the periphery of the insertion part 201c to trigger the adapter 1 to connect and lock. Since it does not require rotation, and can be inserted directly, then the operation is convenient. Furthermore, since no rotation is required, the space for manual operation is small, which can increase the density of connector 2 on the panel.
    [0067] [0067] Additionally, the ejection device 206 is an ejection block provided on the external surface of the insertion part 201c. If the ejection device 206 adopts this structure, the inner sleeve 106 corresponding to the ejection device 206 can be provided with a projection (not shown in the figures) that protrudes from the outer sleeve 205, so that the ejection device 206 can drive the inner sleeve 106 and make the inner sleeve 106 move axially with respect to the outer sleeve 205.
    [0068] [0068] Optionally, the ejection device 206 is an ejection piece spaced from the outer surface of the insertion part 201c. Since the ejection part is disposed at a distance from the insertion part 201c, the ejection part can resist the inner sleeve 106 and extend between the outer sleeve 105 of the adapter and the boundary part 40, so that the adapter be clipped to the connector.
    [0069] [0069] Additionally, the groove is located on the external surface of the area where the ceramic fiber optic ferrule 203 is installed in the insertion part 201c. Because the ferrule 201d fixing part has a greater wall thickness, and after the ceramic fiber optic ferrule 203 is installed in the ferrule fixing part, its intensity is greater. After connector 2 is connected to adapter 1, the groove will be subjected to radial force when connector 2 is pulled. The groove is arranged here to withstand an even greater radial force, which further improves the ability to withstand the withdrawal force.
    [0070] [0070] See figures 1 to 19, in which the present invention additionally provides an adapter | for fiber optic connection, comprising: an adapter body 101, at least one end of the adapter body 101 is a cylindrical boundary part 40, the boundary part 40 is provided with a boundary channel 101a, the adapter body 101a it is provided with a ferrule 42 receiving seat for receiving a ceramic fiber optic ferrule 203, the ferrule 42 receiving seat is located in the middle of the adapter body 101, and the border 40 is provided with a receiving groove 101b which communicates with the neighboring channel 101a; a clamping body, which is movably received in the receiving slot 101b; an outer sleeve 105, movably gloved outside the boundary part 40; wherein the outer sleeve 105 has a first state and a second state; and, when the outer sleeve 105 is in the first state, the outer sleeve 105 resists the clamping body, and causes the clamping body part to insert into the border channel 101a in an irreversible manner; when the outer sleeve 105 is in the second state, a placeholder 101c for the clamping body to exit the boundary channel 101a is provided between the outer sleeve 105 and the opening of the receiving groove 101b; an inner sleeve 106, movably mounted on the boundary part 40, and the inner sleeve 106 is configured to keep the outer sleeve 105 in the first state after being pushed upward in the direction of insertion.
    [0071] [0071] Because, when the outer sleeve 105 is in the first state, part of the clamping body inserts irreversibly into the border channel 101a, and the part that inserts into the border channel 101a is configured to cooperate with the slot of the connector 2, to connect and lock connector 2 and adapter 1, and because the clamping body is resisted and cannot be removed, its border channel 101a makes the connection between connector 2 and adapter 1 very strong and can withstand forces of very high voltage.
    [0072] [0072] Refer to figures 1 to 19, compared to Mode 7, specifically, where the clamping body is a steel ball 104, and the receiving groove 101b is a cylindrical hole. A stop part is provided at the base of the receiving groove 101b, and the stop part is configured to prevent the steel ball 104 from falling out of the receiving groove 101b completely. Specifically, the stop part is a funnel structure provided at the base of the receiving groove 101b. It is anticipated that there are many other methods of stopping, such as a method of providing a knock on the inner wall of the base of the receiving slot 101b. Steel ball 104 is selected as the clamping body because the steel ball itself is of high intensity and not easy to stop when moving up and down in the receiving groove 101b. The base of the receiving groove 101b is also provided with a retracted arcuate stop structure, which is configured to prevent the clamping body from falling out of the receiving groove 101b.
    [0073] [0073] Additionally, the outer sleeve 105 is provided with a resistance block 105a that protrudes from the inner wall. When the outer sleeve 105 moves to the first state, the resistor block 105a is located in the receiving groove 101b and resists the clamping body. By providing a resistance block on the inner wall of the outer sleeve, there is a space reserved for the clamping body in other areas, except the resistance block. Except in the first state, the clamping body will not be resisted and contained in the first state, and the clamping body can also be completely returned to the receiving slot 101b.
    [0074] [0074] In addition, the side of the resistance block 105a near the receiving seat of the ferrule 42 has an inclined surface 111. When the first state is switched to the second state, the inclined surface 111 can guide the clamping body downwards, so that the switching between the first state and the second state becomes more uniform.
    [0075] [0075] Additionally, the bordering part 40 comprises a first section next to the receiving seat of the ferrule 42 and a second section further extended from the first section, and the radius of the first section is greater than that of the second section; an end of the outer sleeve 105 near the receiving seat of the ferrule 42 is gloved in the first section and, during switching between the first state and the second state, the resistor block 105a moves axially in the second section. The difference in diameter formed between the first section and the second section is to create a space for the resistance block 105a to move, and to reduce the diameter of the outer sleeve 105, and thereby reduce the diameter of the integral of the adapter 1 .
    [0076] [0076] Additionally, the rear end surfaces of the inner sleeve 106 are resisted in the outer sleeve 105 by means of an external spring 107, respectively. When the outer sleeve 105 is in the first state, the inner sleeve 106 keeps the outer sleeve 105 in the first state through the outer spring 107. It is conceivable that the outer spring 107 can also be replaced by other elastic elements, such as an elastomer, a repulsive magnet and the like. In this embodiment, a spring is preferably configured.
    [0077] [0077] The outer spring 107 is configured to eject the outer sleeve 105 forward after the inner sleeve 106 is driven by the ejection device 206 until the clamping body is stopped in the groove. At this time, the outer spring 107 keeps the outer sleeve 105 in the original position, that is, the outer spring 107 keeps the outer sleeve 105 in the first state, so that the clamping block 105a has resisted the clamping body, to prevent the clamping body moves away after connector 2 is pulled, which can cause connector 2 and the adapter | are separated in a state where connection is required.
    [0078] [0078] Refer to figures 1 to 19, as an optional modality, in which an axially arranged inner spring 108 is provided between the inner sleeve 106 and the boundary part 40. The inner spring 108 is provided so that the inner sleeve 106 and the outer sleeve 105 can be ricocheted back as a whole after the connector and adapter are disconnected.
    [0079] [0079] Additionally, the elastic force of the external spring 107 is greater than that of the internal spring 108. The elastic force of the external spring 107 is made greater than that of the internal spring 108.
    [0080] [0080] Specifically, the inner sleeve 106 is combined between the outer sleeve 105 and the boundary part 40, and the inner sleeve 106, the outer sleeve 105 and the boundary part 40 can slide in relation to each other, which enables the adapter | to switch between the first state and the second state.
    [0081] [0081] Additionally, a retaining ring is provided at the surface end of the outer sleeve 105 and the boundary part 40 facing the inner sleeve 106, respectively. The retaining ring prevents inner sleeve 106 from being pushed out of outer sleeve 105 by inner spring 108 and outer spring 107.
    [0082] [0082] See figure 20, as an optional modality, in which the clamping body comprises an elastic arm 43 extending from the boundary part 40, and a clamping block 44 is provided at the end of the elastic arm 43. When the outer sleeve 105 is in the first state, the elastic arm 43 is in a state of undirected elastic deformation, and the clamping block 44 is completely received in the receiving groove 101b. When the outer sleeve 105 is in the first state, the outer sleeve 105 resists in the clamping block 44 and the clamping block 44 partially extends into the boundary channel 101a.
    [0083] [0083] Compared to the clamping method using steel balls, the mode in which the clamping block 44 is provided at the end of the elastic arm 43 can cause the clamping block 44 to automatically exit the border channel 101a when the outer sleeve 105 is retracted to the second state. However, due to the friction of the elastic arm 43 on the outer sleeve 105, greater force is required to switch between the first state and the second state.
    [0084] [0084] The invention also provides a fast plug-in fiber optic connection assembly (insertion and removal), comprising an adapter 1 and a connector 2. The adapter | comprises an adapter body 101, a clamping body, an outer sleeve 105 and an inner sleeve 106.
    [0085] [0085] At least one end of the adapter body 101 has a cylindrical boundary part 40. The boundary part 40 is provided with a boundary channel 101a. The adapter body 101 is provided with a ferrule 42 receiving seat to receive a ceramic fiber optic ferrule 203. The ferrule 42 receiving seat is located in the middle of the adapter body 101, and the border 40 is provided with a receiving slot 101b that communicates with the neighboring channel 101a.
    [0086] [0086] The clamping body is movably received in the receiving slot 101b.
    [0087] [0087] The outer sleeve 105 is movably gloved outside the boundary part 40. The outer sleeve 105 has a first state and a second state. When the outer sleeve 105 is in the first state, the outer sleeve 105 resists in the clamping body and causes the clamping body part to insert into the border channel 101a in an irreversible manner. When the outer sleeve 105 is in the second state, a placeholder 101lc for the clamping body to exit the border channel 101a is provided between the outer sleeve 105 and the opening of the receiving groove 101b.
    [0088] [0088] The inner sleeve 106 is movably mounted on the border 40, and the inner sleeve 106 is configured to keep the outer sleeve 105 in the first state after being pushed upward in the direction of insertion.
    [0089] [0089] The connector 2 comprises: a part of the main body 201a, which is provided with a cavity 201b; an optical cable 215, which is mounted on the main body part 201a, and the optical cable 215 extends into the cavity 201b; an insertion part 201c, which is located at one end of the main body part 201a; an end of the remote insertion part 201c of the main body part 201a is provided with a ceramic fiber optic ferrule 203; the insertion part 201c is provided with a groove to clamp an adapter corresponding to the connector; and at the same time,
    [0090] [0090] Compared with the locking force of the locking device (buckle) used by the existing standard connector, the locking force of the connection method using the clamping body and the groove is even stronger. The connection method using the clamping body and the groove is best suited for complex outdoor scenarios and can withstand even greater withdrawal force. In addition, the insertion force required during insertion is small, and the locking force is large when locked. When pulled out, the connector can be evenly pulled out, and the withdrawal force is small, which has the characteristic of convenient operation, and can effectively solve the problems of inconvenient insertion and removal operations (plugging and unplugging) and insufficient locking force in the existing fiber optic connection assembly.
    [0091] [0091] See figures 1 to 8, in which the modality of the present invention provides a fiber optic connection assembly with a quick plug, comprising an adapter | and a connector 2. As shown in figure 1, adapter 1 comprises an adapter body 101 capable of forming a butt joint with connector 2 at both ends. The adapter body 101 contains a ceramic sleeve 102 required to make a butt joint with the fiber optic ceramic ferrule 203 of connector 2. Each end of the adapter body 101 is provided with a locking structure.
    [0092] [0092] As shown in figure 3, the connector 2 comprises a plug body 201. The interior of the plug body 201 contains an optical fiber 202. The front end of the optical fiber 202 is connected with a ceramic fiber ferrule 203. The front end face of the 203 ceramic fiber ferrule exposes the exterior of the plug body 201. As shown in figure 4, the outer surface of the plug body 201 is provided with a directional boundary projection 204 adapted to the directional boundary groove 103 of adapter 1, and the specific distribution position and number of directional boundary projections 204 are aligned with those of the directional boundary grooves to cooperate with directional boundary groove 103 during the top joint, and play a guide role to ensure the direction of rotation of connector 2 during the butt joint. The exterior of the plug body 201 is provided with a plug sleeve 205, and the front end of the plug sleeve 205 is provided with a projection ejection device 206 to cooperate with the inner sleeve 106 of adapter 1 during the butt joint. , and drives the inner sleeve 106 to slide along the direction of the insertion with respect to the adapter body 101. The outer surface of the plug body 201 is provided with an annular groove 207 along its circumferential direction, and is configured to cooperate with the steel ball 104 during the butt joint to play a clamping and locking role. When the adapter | and connector 2 make the top joint, the ejection device 206 of connector 2 drives the inner sleeve 106 of the adapter | to slide along the insertion direction in relation to the adapter body 101 and, at the same time, the outer sleeve 105 also slides along the insertion direction of the connector 2 under the action of the external spring 107. After sliding, the sleeve outer 105 presses the steel ball 104 into the annular groove 207 of connector 2 through the inclined surface 111 of the wall on the inner side of the outer sleeve 105, and the ball is then
    [0093] [0093] See, specifically, figure 5, where the adapter | and connector 2 are in a pre-jointed top state, outer spring 107 and inner spring 108 of adapter 1 are both in an uncompressed state. The decompressed state referred to here does not comprise the pre-compressed state of the spring after being installed. In general, after the spring is installed, it is usually in a pre-compressed state in relation to the original length. The outer sleeve 105 of the adapter 1 is in a state where the steel ball 104 is not compressed firmly. At this point, the steel ball 104 can move within the gap between the outer sleeve 105 and the adapter body 101, which ensures that, before the annular groove 207 of connector 2 reaches the predetermined position, the ball steel 104 does not affect the insertion of connector 2.
    [0094] [0094] See figure 6, where the adapter | and connector 2 are in the process of inserting the top joint, where the projected ejection device 206 in connector 2 pushes the inner sleeve 106 of the adapter | to slide in the direction in which connector 2 is inserted. Because the elastic force of the outer spring 107 is greater than the elastic force of the inner spring 108, the slip of the inner sleeve 106 preferably compresses the inner spring 108, and the outer sleeve 105 is driven through the outer spring 107 to slide on the direction in which connector 2 is inserted. When the connector 2 is in the predetermined position, the outer sleeve 105 is exactly in the state of being pressed against the steel ball 104 firmly. At this point, the slidable outer sleeve 105 presses the steel ball 104 into the annular groove 207 of connector 2 through the inclined surface 111 of its inner wall, and the ball is then clamped. The steel ball 104 cooperates with the annular groove 207 of connector 2, so that adapter 1 and connector 2 cannot move, thereby completing the locking operation of connector 2.
    [0095] [0095] As shown in figure 7, when connector 2 is ready to be pulled out of adapter 1, the outer sleeve 105 of the adapter | it is first manually slid in the direction along which the connector 2 is pulled out, so that the steel ball 104 can be moved up and down in the gap between the outer sleeve 105 and the adapter body 101, to achieve the purpose of unlocking steel ball 104 and annular groove 207 of connector 2. As shown in figure 8, when steel ball 104 is in the unlocked state, connector 2 continues to be moved in the direction of being pulled out. At this time, steel ball 104 is released from annular groove 207 of connector 2, there is no locking function, and connector 2 can be uniformly pulled out of adapter 1.
    [0096] [0096] Through the exposed operations, the plugging and unplugging operations of the adapter | and connector 2 can be completed simply and quickly, and the locking force is reliable, which effectively solves the problems of inconvenient plugging and unplugging operations and insufficient locking force of the existing fiber optic connection assembly.
    [0097] [0097] Based on the above, in order to solve the problem of poor dustproof and waterproof performance of existing connector 2 and adapter 1, as shown in figure 9, the contact surface between the plug body 201 of connector 2 and adapter body 101 is flush with at least one O-ring seal 208. The design of the O-ring seal 208 allows a closed space to be formed between connector 2 and the adapter 1. Specifically, a closed space is formed in the area on the left side of the O-ring in figure 9. The closed space ensures that a good dustproof and waterproof effect can be achieved after connector 2 and adapter 1 make the butt joint. In addition, when adapter 1 is installed on the installation interface, the contact surface of the adapter body 101 and the installation interface is provided with a flat sealing washer 112. The design of the flat sealing washer 112 makes the adapter | and the installation interface also have a good dustproof and waterproof effect. In this embodiment, the O-ring seal 208 and the flat seal washer 112 are made of rubber or silicone. Furthermore, the number of O 208 sealing rings is defined as two, to form a double O 208 sealing ring design.
    [0098] [0098] Additionally, it can be understood that, in a real application, as shown in figure 10, when adapter 1 is not a butt joint with connector 2, a protective plug 3 can be inserted in adapter 1, and the protective plug 3 is provided with an ejection device 206, an annular groove 207 and an O-ring seal 208 with the same structures as those provided in connector 2. Similarly, it can be understood that, in a real application, the As shown in figure 11, when the connector 2 is not a top joint with the adapter 1, a protective cover 4 can be gloved on the body of the plug 201 of the connector 2, and the protective cover 4 is connected to the jacket of the plug 205 of the connector 2 through a thread.
    [0099] [0099] Furthermore, it can be understood that, in a real application, the fiber optic connection assembly can be designed as a "waterproof end-type locking type" or a "waterproof locking type" double-ended water ”according to usage requirements. As shown in figure 12, the "waterproof single-ended locking type" means that one end of the adapter body 101 has a locking structure for making butt joint with the aforementioned connector 2 which has waterproof functions dust, waterproof and locking, and the other end does not have a locking structure and is configured to perform butt joint with the existing standard connector 2. As shown in figure 13, the “waterproof locking type 'double-ended water ”means that both ends of the adapter body 101 have a locking structure, and both are configured to make the top joint with the aforementioned connector 2 which has dustproof, waterproof functions and locking.
    [00100] [00100] Furthermore, it can be understood that the adapter body 101 of the present invention can be selected from the current industry standard type adapter body 101, comprising Square Connector (SC), Ferrule Connector (FC), Single Luminescent Connector (LC), dual LC, type E2000, etc. According to the different methods of grinding the end face of the 203 fiber optic ceramic ferrule, the connector 2 can be further divided into the end face of the UPC pin body as a physical end face and body end face of the APC pin as a physical end face of the angle. Therefore, the adapter body 101 adapted to the industry standard type, connector 2 of the present invention, can be further divided into type SC-APC / UPC, type FC-APC / UPC, type LC-APC single / UPC, type LC - Dual APC / UPC, type E2000-APC / UPC and the like.
    [00101] [00101] In order to better understand the present invention, the aforementioned fiber optic connection assembly is further described in detail through the various specific modalities.
    [00102] [00102] See figure 14, which shows a connector mode
    [00103] [00103] See figure 15, which shows the mode after connector 2 is a top joint with adapter 1. As shown in the figure, after connector 2 is a top joint with adapter 1, the sleeve outer 105 of adapter 1 presses steel ball 104 into the annular groove 207 of connector 2 through the inclined surface 111 of its inner wall and locks it. Steel ball 104 cooperates with annular groove 207 of connector 2 to make the adapter | and connector 2 unable to move, thereby achieving the effect of clamping and locking, and the locking force is reliable.
    [00104] [00104] See figure 16, which shows a modality of the protective cover 4. The left side of the protective cover 4 is provided with an annular structure to fix the traction rope or other traction tools of the fiber optic cable in the duct. See figure 17, which shows that protective cap 4 is gloved on connector 2. As shown in the figure, protective cap 4 and plug sleeve 205 of connector 2 are connected through threads, and threads are added with glue thread lock to ensure firmness and water resistance after connection.
    [00105] [00105] See figure 18, which shows a modality of the protective plug 3. As shown in the figure, the protective plug 3 has the same ejection device 206, the same annular groove 207, and the same sealing ring in the shape of The 208 provided in the connector 2 described above. See figure 19, where the modality shows that the aforementioned protective plug 3 is inserted into adapter 1. As shown in the figure, after the aforementioned protective plug 3 is inserted into adapter 1, the ejection device 206 of the protective plug 3 pushes the inner sleeve 106 of the adapter 1 so that the outer sleeve 105 of the adapter 1 slides forward in the direction of insertion, and press the steel ball 104 into the annular groove 207 of the protective plug 3 through the inclined surface 111 from the inside wall and lock it. The steel ball 104 cooperates with the annular groove 207 of the protective plug 3, so that the adapter 1 and the protective plug 3 cannot move, thereby achieving the clamping and locking effect, and the locking force is reliable .
    [00106] [00106] The present invention is not limited to the aforementioned modalities. Ordinary technical personnel in the technical field can also make some improvements and polishes under the premise of not departing from the principle of the present invention, and these improvements and polishes must be included in the scope of protection of the present invention.
