    DETAILED DESCRIPTION
    To make more clear the problems solved, the solutions adopted and the effects obtained from the present description, the solution of the present description is further described with reference to the accompanying drawings and via an embodiment.
    As shown in FIGS. 1 to 15, the present embodiment provides an optical fiber adapter for sealing against dust and light. Specifically, the fiber optic adapter for dust and light sealing comprises an adapter body 1 and a light-tight plate assembly 5. The adapter body 1 comprises a body portion 17 and a lid 18. The body portion 17 is configured to form a concave space provided with openings in two directions. The cover 18 engages with the body portion 17 and closes one of the openings of the concave space to form an orifice 11 provided with an opening. A plurality of orifices 11 are provided on two sides of the adapter body 1. The orifices 11 are configured to be connected to optical fiber connectors 4. The light-tight plate assembly 5 comprises a watertight plate light 51 capable of closing and opening the orifice 11. Each pair of adjacent orifices on the same side shares a light-tight plate 51. In at least one embodiment, each side of the fiber optic adapter has 4 orifices 11, and each pair of adjacent orifices 11 share a light-tight plate 51. FIG. 5 illustrates two light-tight plates 51. Optical fiber connectors 4 are inserted into orifices 11 corresponding to the one of the two light-tight plates 51. Therefore, this light-tight plate 51 opens the orifices 11. The orifices 11 corresponding to the other of the two light-tight plates 51 are inactive and therefore closed to prevent external dust and light from entering the fiber optic adapter. Two ports 11 of the fiber optic adapter of the present embodiment are protected at the same time by a light-tight plate 51. It is no longer necessary to provide a light-tight plate 51 for each orifice individually, reducing the number of light-tight plates 51. More importantly, this configuration reduces assembly time of the fiber optic adapter, improves assembly efficiency, and significantly reduces manual assembly costs. In addition, usually, two orifices 11 of the optical fiber adapter are used in cooperation, and it is therefore generally impossible to use one of the orifices 11 by causing the other orifice 11 to be open and polluted.
    A first end of the light-tight plate 51 is provided with a rotation shaft 511. Two adjacent orifices 11 sharing a light-tight plate 51 are paired orifices. Opposite inner walls of the paired orifices are respectively provided with a rotation slot 161 adapted to the rotational shaft 151. The light-tight plate 51 rotates about the rotation shaft 511 to open or close the paired orifices. The rotation slot 161 is arranged from one side of the body portion 17 facing the cover 18 in a direction away from the cover 18. The cover 18 covers the rotation slot 161.
    When the light-tight plate 51 is mounted, the light-tight plate 51 can be loaded through the opening which can be closed by the cover 18, and then the cover 18 and the body part 17 are set. engaged to close the opening. The editing process is simple. The cover 18 and the body portion 17 are assembled by engagement. This assembly is simple, allows the cover 18 to be securely attached to the body portion 17 and does not require additional fixed structures. In addition, the cover 18 is engaged with one side of the body portion 17 rather than enclosing a frame and then adjusting it on the body portion 17. Therefore, a thickness of an engagement portion the cover 18 may be larger, and a cover material is not limited, widening the material selection space. In the present embodiment, the body portion 17 is integrally formed, ensuring a structural strength of the body portion 17. The body portion 17 and the cover 18 are made of the same material, for example a plastics material , and can thus be formed by injection molding. The body portion 17 and the cover 18 have the same color so that a color of the entire adapter body 1 is uniform when the cover 18 is tightened on the body portion 17.
    In the present embodiment, two adjacent orifices 11 sharing a light-tight plate are separated by a separating plate 15. The separating plate 15 is provided with a prevention zone 151. A middle part of the The light-tight plate 51 is located at the separating plate 15. Each of the two sides of the light-tight plates 51 is located inside a respective one of the two orifices 11. The prevention zone 151 is adapted for motion tracking of one end of the light-tight plate 51 to avoid interfering with the light-tight plate 51. Specifically, the light-tight plate 51 in the present embodiment is rotated in the orifice 11, and therefore, the prevention zone 151 is arc-shaped.
    As illustrated in FIG. 5, the light-tight plate assembly 5 further comprises an elastic needle 52. The elastic needle 52 has two resilient ends 521. The light-tight plate 51 is connected in such a manner that rotating to the adapter body 1. One of the two resilient ends 521 abuts against the light-tight plate 51, and the other of the two resilient ends 521 abuts against an inner wall of the adapter body 1 , so that the orifice is closed by the light-tight plate 51. In FIG. 5, the two elastic ends 521 of the elastic needle 52 are in a free open state. After actual assembly, a vertical elastic end 521 abuts against the inner wall of the adapter body 1 (here, an inner wall of the cover 18). When the orifice 11 is inactive, the elastic needle 52 presses the light-tight plate 51 in a closed state. When the optical fiber connector 4 is inserted into the orifice 11, the light-tight plate 51 is pressed into an open state and the two elastic ends 521 of the elastic needle 52 are brought closer to each other.
    In the present embodiment, a medial portion of the elastic needle 52 is arc-shaped, so that the two elastic ends 521 of the elastic needle 52 can remain open. As shown in Figures 5, 9 and 10, in the present embodiment, a through slot is arranged from the first end of the light-tight plate 51 inward and passes through the light-tight plate 51. The through slot is provided transversely with a sleeve shaft 512. The through slot is divided by the sleeve shaft 512 into a limiting slot 513 closer to the first end and into a limiting hole 514 further away from the first end. . The middle portion of the elastic needle 52 surrounds the sleeve shaft 512 and is housed in the limiting slot 513. The arcuate middle portion of the elastic needle 52 also facilitates rotation after the middle portion of the elastic needle 52 has surrounded the sleeve shaft 512. An elastic end 521 of the elastic needle 52 protrudes from the limiting hole 514 and abuts against the light-tight plate 51. Another elastic end 521 of the elastic needle 52 abuts against the inner wall of the adapter body 1. The limiting hole 514 can confine the position of the elastic end 521 passing therethrough. After the middle part of the elastic needle 52 has surrounded the sleeve shaft 512, the limiting slot 513 confines the elastic needle 52. The limiting slot 513 and the limiting hole 514 can perfectly confine the elastic needle. 52. In addition, the elastic needle 52 can be hidden in the limiting slot 513 to avoid being exposed outside the rotation shaft 511 and to interfere with the inner wall of the adapter body 1 In addition, as shown in FIG. 4, the inner wall of the adapter body 1 is provided with corresponding housing slots 162 at a position of the resilient end 521 and a position of the sleeve shaft 512. In the In this embodiment, the cover 18 of the adapter body 1 covers the light-tight plate 51, so that the housing slots 162 are on an inner surface of the cover 18. The housing slots 162 may not be alone Furthermore, the elastic end 52 and the cover 18 can be prevented from becoming interfered with by the resilient end 521. In the present embodiment, the through slot is located at a position corresponding to the separating plate 15. As shown in FIG. therefore, the elastic needle 52 is also located on the separator plate 15 for pressing the light-tight plate 51 from the middle, facilitating the application of a uniform force on the light-tight plate 51 and occupying not a space of the orifice 11.
    In the present embodiment, the optical fiber connector 4 is provided with a compressible and rectifying protrusion 42. A side wall of the orifice 11 is provided with a recess 14 to receive the projection 42, and the recess 14 does not pass through the side wall of the orifice 11. After the adapter body 1 has been disassembled into the cover 18 and the body portion 17, the cover 18 and the body portion 17 are not configured in frame structures, but are similar to semi-enclosed structures. Therefore, at the time of injection molding, the recess 14 which does not penetrate the inner wall can be arranged internally, so that the recess 14 of the adapter body 1 does not pass through the inner wall and does not form a through hole, without additionally using a metal frame for attachment. Such an arrangement saves costs and facilitates assembly. Each concave space has two openings, and when the cover 18 covers one of the openings from the outside to form an orifice 11, the space inside the orifice 11 is not affected. The cover 18 is engaged with the body portion 17, providing a simple assembly and a firm attachment between the cover 18 and the body portion 17.
    To make the engagement between the cover 18 and the body portion 17, the cover 18 includes a cover body portion and first clamping portions 181 projecting from both sides of the cover body portion. The body portion 17 is provided with first deflection portions 171 on outer walls on two sides of the concave space. The lid body portion closes the opening, and the first clamping portions 181 are clamped to the first deflection portions 171. Specifically, a clamping hole 1811 is provided on the first clamp portion 181. The first deflection portion 171 protrudes from the outer wall of the body portion 17. A guide surface 1711 is arranged on one side of the first deflection portion 171 near the cover 18 to facilitate clamping of the first clamp portion 181. When the first clamping portion 181 is clamped toward the body portion 17, the first clamping portion 181 is progressively opened along the guide surface 1711 until the clamping hole 1811 is tightened on the first deflection portion 171 The guide surface 1711 can guide the first clamping portion 181 to open, facilitating completion of the clamping process. The first deflection portions 171 and first clamping portions 181 arranged on two sides ensure a balanced force between the two sides of the cover 18 and the body portion 17. To further maintain the balanced force, the first clamping portions 181 on the two sides of the body portion 17 may be symmetrically disposed. To improve the clamping between the body portion 17 and the cover 18, two or more first two clamping portions 181 may be disposed on each side of the body portion 17.
    As illustrated in Figures 4, 6 and 7, in the present embodiment, multiple concave spaces are provided on one side of the adapter body 1. Adjacent concave spaces are separated by a spacer plate 19 The lid body portion closes openings of the multiple concave spaces to form multiple orifices 11. The spacer plate 19 is provided with a second deflection portion 191. A second clamp portion 182 projects from the cover body and is tightened on the second deflection portion 191. When the cover 18 simultaneously closes multiple concave spaces, to further increase the clamping force between the cover 18 and the body portion 17, an additional second deflection portion 191 may be arranged in a central area of the lid body portion (a position corresponding to the spacer plate 19) to increase the clamping between a center of the lid body portion and the body portion 17. A concave space may form one or more portions 11. In the present embodiment, a concave space forms two orifices 11, and pairs of two adjacent orifices are each separated by a separating plate 15.
    More specifically, the second clamping portion 182 comprises an elastic arm 1821 and a hook 1822 projecting from one end of the elastic arm 1821. The second deflection portion 191 is a first housing zone 1911 and a second housing zone 1912 arranged on the spacer plate 19. The first housing zone 1911 houses the elastic arm. 1821. The second housing area 1912 houses the hook 1822. The hook 1822 is clamped on a slot wall of the second housing area 1912 to tighten the second clamping portion 182 on the spacer plate 19. The first housing area housing 1911 and the second housing area 1912 respectively house the elastic arm 1821 and the hook 1822, preventing the second clamping portion 182 from projecting from the spacer plate 19 to interfere with the optical fiber connector 4 in the port 11.
    In the present embodiment, the optical fiber adapter further comprises a sleeve 2 and a locking sleeve 3. Orifices 11 are provided on both sides of the adapter body 1. The pairs of two orifices opposite ends 11 on both sides are each connected by a sleeve hole 12. A first end of the sleeve hole 12 projects inwardly to form a first pin portion 121. In the present embodiment, a first end sleeve hole 12 is located in port 11. An inner wall of an orifice 11 connected to a second end of sleeve hole 12 is provided with a depressed locking sleeve clamping zone 13. locking sleeve clamping member 13 may be a hole, slot or other structure.
    The sleeve 2 is configured to align optical fibers 41 extending from two ends of the sleeve 2. The sleeve 2 may be a copper pipe. So that the sleeve 2 is mounted in the sleeve hole 12, the sleeve 2 may be provided with a slot in an axial direction to allow the sleeve 2 to be compressed to a certain extent.
    The locking sleeve 3 is injection molded. The locking sleeve 3 is provided with a through locking hole 31. The locking hole 31 has the same diameter as the sleeve hole 12. The locking sleeve 3 protrudes from an outer wall of the locking hole 31 to form a locking sleeve clamping portion 32. The locking sleeve clamping portion 32 is expandable and compressible in a direction perpendicular to an axial direction of the locking hole 31. A first end of the locking hole 31 projects toward the interior to form a second pin portion 311. When the locking sleeve clamp portion 32 is opened and tightened in the locking sleeve clamping area 13, a second end of the locking hole 31 is connected to the second end. sleeve hole 12 for housing sleeve 2, and both ends of sleeve 2 are confined through the first pin portion 121 and the second pin portion 311, respectively.
    Since the locking sleeve 3 has a locking sleeve clamping portion 32 that can be opened and compressed, the locking sleeve 3 can be pushed inward from the outside of the hole 11 into the hole. When the locking sleeve clamping part 32 enters the depressed locking sleeve clamping area 13, the locking sleeve clamping portion 32 can be opened and tightened on the locking sleeve clamping region. 13, and the locking hole 31 can be aligned with the sleeve hole 12 without hot pressing, welding or the like. The sleeve hole 12 is provided with the first pin portion 121 and the locking hole 31 of the locking sleeve 3 is provided with the second pin portion 311. One end of the sleeve 2 can be placed in the locking hole. 31 or the sleeve hole 12 in advance. While the locking sleeve 3 is pressed, another end of the sleeve 2 is gradually inserted into the sleeve hole 12 or the locking hole 31. When the sleeve hole 12 is aligned with the locking hole 31, the two ends of the sleeve 2 are respectively confined by the first pin portion 121 and the second pin portion 311, completely locked in the sleeve hole 12 and the locking hole 31, and thus locked in the adapter body 1.
    The fiber optic adapter of the present description uses the locking sleeve 3 to lock the sleeve 2. As it is pressed, the sleeve 2 is not pressed by the first pin portion 121 or the second pin portion 311 and this does not affect the accuracy of the sleeve 2. Hot pressing or welding is not required in the process of assembling the sleeve 2, and the sleeve 2 can be assembled by a method cold assembly. The cold assembly process is simple and easy, does not affect other components, and improves the quality of the fiber optic adapter. Likewise, the adapter body 1 can be integrally formed at the sleeve hole 12, improving the structural strength of the adapter body 1.
    To allow the locking sleeve clamp portion 32 to be expandable and compressible in the direction perpendicular to the axial direction of the locking hole 31, as shown in FIG. 8, in the present embodiment, a The end of the locking sleeve clamping part 32 is provided with a rocking arm 321 in an inclination direction opposite to the axial direction of the locking hole 31. The rocking arm 321 is able to remain open and compressed. The rocker arm 321 may be deformed inward when subjected to pressure in a lateral direction and may be straightened when space permits, so that the lock sleeve clamp portion 32 may be clamped into In the present embodiment, an outer end of the swing arm 321 tilts toward the second pin portion 311. The locking sleeve 31 is pressed into the orifice 11 from the second pin portion 311 to the sleeve hole 12 and, therefore, when the outer end of the swing arm 321 tilts toward the second pin portion 311, an inverse deflection can be formed, effectively preventing the sleeve from locking 3 out of the locking sleeve clamping area 13. To facilitate bending of the swinging arm 321, the locking sleeve clamping portion 32 is provided with a locking slot. bending 322 when rotating an inner end of the swing arm 321. The side walls of the bending slot 322 do not compress each other when the swing arm 322 is bent, facilitating the bending of the swing arm 321.
    In addition to the method of configuring the swing arm 321, in the present embodiment, a separation slot 312 may also be disposed inwardly from one end of the locking hole 31. The sleeve clamping portion The outer walls on both sides of the separation slot 312 close inwardly when the locking sleeve clamp portion 32 is pressed. The provided separation slot 312 allows the outer walls on both sides of the separation slot 312 to close inwardly, thereby allowing the locking sleeve clamp portion 32 to move inwardly and open to the outside. In addition, a rigidity of the locking sleeve 3 can be adjusted by adjusting a length of the separation slot 312, i.e., the capabilities of the locking sleeve clamp portion 32 to be compressed and to remain open are adjusted. When the length of the separation slot 312 is longer, the locking sleeve clamp portion 32 can be compressed more easily. When the length of the separation slot 312 is shorter, the locking sleeve clamp portion 32 can not be easily squeezed and can remain open more easily. The configuration in which the locking sleeve 3 is provided with the separation slot 312 may be combined with the configuration in which the locking sleeve clamp portion 32 is provided with the rocking arm 321, so that the portion of Locking sleeve clamping 32 can be compressed and opened by two structures and thus structural reliability can be further guaranteed.
    In the present embodiment, the locking sleeve clamp portion 32 is located on the second end of the locking hole 31, and the side wall of the orifice 11 connected to the second end of the sleeve hole 12 is provided with the corresponding locking sleeve clamping area 13. After tightening on the locking sleeve clamping area 13, the locking sleeve clamping portion 32 can secure the locking sleeve 3 directly from the second end. of the locking hole 31, so that the second end of the locking hole 31 can be firmly connected to the second end of the sleeve hole 12. To further maintain the locking sleeve 3 coupled to the sleeve hole 12, the inner wall where is located the second end of the sleeve hole 12 is adapted to a surface of the locking sleeve clamp portion 32 near the sleeve hole In the present embodiment, the inner wall where the second end of the sleeve hole 12 is located and the surface of the locking sleeve clamp portion 32 near the sleeve hole 12 are both flat surfaces. The inner wall where the second end of the sleeve hole 12 is located is perpendicular to an axial direction of the sleeve hole 12. After the sleeve clamp portion 32 is tightened on the locking sleeve clamping area 13, the surface the locking sleeve clamp portion 32 near the sleeve hole 12 abuts the inner wall where the second end of the sleeve hole 12 is located, and the entire flat surface can stably support the locking sleeve 3 to maintain a stability of the locking sleeve 3.
    In the present embodiment, locking sleeve clamping portions 32 are arranged symmetrically on two sides of the locking sleeve 3, so that both sides of the locking sleeve 3 are uniformly subjected to forces, guaranteeing further that the locking sleeve 3 is securely coupled to the sleeve hole 12. The end of the locking sleeve clamping portion 32 may be arranged in a straight line. The locking sleeve clamping zone 13 is a bar-shaped slot. After tightening the lock sleeve clamp portion 32 on the lock sleeve clamping area 13, the sleeve clamping portion 32 is prevented from rotating and the entire sleeve clamping portion 32 is uniformly subjected to forces.
