    TECHNICAL AREA
    The present invention relates to the field of physical connection technology for optical communication and, in particular, an optical fiber connector.
    BACKGROUND
    An optical fiber connector, a device used to detachably connect (mobile) optical fibers, precisely connects two end faces of the optical fibers so that the light energy output by a optical transmission fiber is maximally coupled to a receiving optical fiber.
    [0003] Figure 1 illustrates an optical fiber connector of the relevant art. The optical fiber connector comprises a connector body 1a and a back box 8 'which is attached to one end of the connector body 1' to protect an optical cable 9 '. The optical cable 9 'is inserted into the connector body 1' through the back box 8 'and then connected to one end of a fiber tip 10'. The other end of the fiber tip 10 'is exposed from the other end of the connector body 1'. The optical fiber connector further comprises a locking mechanism 2 '. The locking mechanism 2 'comprises a flexible rocking arm 21' extending obliquely from the outside of the connector body 1 ', locking projections 22' protruding from both sides of the rocking arm 21 'and a driving arm 23 'connected to the rocking arm 21'. When the optical fiber connector is inserted into an adapter, the locking projections 22 'are engaged in a locking slot of the adapter and a rear end of the driving arm 23' is exposed outside the adapter. 'adapter. In this way, the locking slot locks the locking protrusions 22 'so that the entire optical fiber connector can not be removed directly from the adapter. When the adapter and the fiber optic connector are to be separated from each other, an operator presses on the rear end of the drive arm 23 'to drive a rear end of the rocker arm 21' to move towards the outside of the connector body 1 'so as to cause the locking projections 22' to disengage from the locking slot, so that the optical fiber connector can be removed from the adapter.
    [0004] A disadvantage of the above optical fiber connector is that sufficient operating space must be reserved on a mounting panel for mounting the adapter so as to provide the drive arm pressure operation. 23. As a result, the fiber optic connector occupies a large space and adapters on the mounting panel can not be arranged in a high density stack arrangement, thereby affecting mounting density of the mounting panel.
    Similarly, the art concerned provides an optical fiber connector in which a connector body is unlocked from an adapter by pulling a handle. However, the handle directly pulls the rear end of the drive arm to move it, causing the rear end of the swing arm to approach the outside of the connector body, so as to cause the locking projections to become disengage from the lock slot. The operation requires a big effort. SUMMARY [0006] This description provides an optical fiber connector.
    The optical fiber connector comprises: a connector body, a locking mechanism, a frame, a motion conversion assembly, and a handle.
    [0008] A first end of the connector body is configured to be inserted into an adapter.
    The locking mechanism comprises a rocking arm, a locking projection and a drive arm. The swing arm extends obliquely from the connector body, the lock projection projects outwardly from one side of the swing arm, and a first end of the drive arm is connected to the swing arm.
    A second end of the connector body is connected by the frame to a rear housing in which an optical cable is inserted. The motion conversion assembly is rotated to the frame. A first end of the motion conversion assembly is movably connected to a second end of the drive arm. A second end of the motion conversion assembly is connected to the handle. The motion conversion assembly is capable of converting a translation of the handle into a rotation of the motion conversion assembly to allow the first end of the motion conversion assembly to press on the second end of the arm drive, so as to unlock the connector body from the adapter.

    DETAILED DESCRIPTION
    The solution of the present description is further described together with the following embodiment and the accompanying drawings. It should be understood that the embodiment presented below is intended to illustrate and not to limit the present description. To facilitate the description, only a portion, not all, related to the present description is illustrated in the accompanying drawings.
    As shown in Figures 2 to 12, the present description provides an optical fiber connector. The fiber optic connector is configured to be connected to an adapter to connect, distribute, or redirect optical fibers that are connected to the connector and the adapter. The optical fiber connector comprises a connector body 1, a locking mechanism 2, a motion conversion assembly 3, a frame 4 and a handle 7. A first end of the connector body 1 is configured to be inserted into the connector. adapter. A second end of the connector body 1 is connected to a first end of the frame 4. A second end of the frame 4 is connected to a rear housing 8 in which an optical cable 9 is inserted. The locking mechanism 2 comprises a tilting arm 21, a locking projection 22 and a driving arm 23. The tilting arm 21 extends obliquely from the connector body 1. The locking projection 22 projects outwardly from one side of the rocker arm 21 and is configured to lock the connector body 1 to a locking slot of the adapter. A first end of the drive arm 23 is connected to the swing arm 21. A second end of the drive arm 23 is connected to a first end of the motion conversion assembly 3. A second end of the conversion assembly 3 is connected to the handle 7. The motion conversion assembly 3 is configured to convert a translation of the handle 7 into a rotation of the motion conversion assembly 3.
    When pulled, the handle 7 causes the motion conversion assembly 3 to rotate and thus the second end of the drive arm 23 is pressed. At the same time, the rocker arm 21 connected to the first end of the drive arm 23 is driven to move in a horizontal direction. When an angle included between the rocking arm 21 and the horizontal direction is less than a certain degree, the locking projection 22 is disengaged from the locking slot of the adapter, thus unlocking the connector body 1 from the adapter.
    The optical fiber connector provided by the present description can be unlocked from the adapter simply by pulling the handle. This avoids a case where the locking protrusion 22 is disengaged from the locking slot only when the drive arm 23 is squeezed from the top of the connector, and minimizes an operating space for pressing the drive arm 23 when the The connector is inserted or removed so that multiple adapters and / or connectors can be stacked more closely, i.e. the adapters and / or connectors can be mounted at a higher density. In addition, the handle 7 is connected to the drive arm 23 via the motion conversion assembly 3 capable of converting the translation of the handle 7 into rotation of the motion conversion assembly 3. In operation, when is just slightly drawn, the handle 7 causes the motion conversion assembly 3 to rotate, so that one end of the motion conversion assembly 3 engages the drive arm 23 presses the arm of drive 23 to allow the lock projection 22 to disengage from the lock slot. Such an operation is convenient and effortless.
    Referring to Figures 2 to 9, the motion conversion assembly 3 comprises a reversible plate 31 and a sliding handle member 32. A medium of the reversible plate 31 is pivoted to the frame 4. The reversible plate 31 can rotate about a pivot axis of the reversible plate 31. A first end of the reversible plate 31 cooperates with the second end of the drive arm 23. A second end of the reversible plate 31 cooperates with a first portion 321 of the sliding handle element. A second portion 322 of the handle sliding member is detachably connected to the handle 7. The sliding handle member 32 is slidably disposed on the frame 4. When pulled, the handle 7 brings the sliding handle member 32 to slide so as to cause the reversible plate 31 to rotate.
    Specifically, a lower end face of the first portion 321 of the sliding handle member is provided with a first sliding projection 3213 projecting downward, accordingly the frame 4 is provided with a first slot. sliding member 41 extending in a direction of movement of the handle 7. The first sliding projection 3213 is slidable in the first sliding slot 4L An upper end face of the first portion 321 of the sliding handle member is provided with a drive block 3211 projecting upwards, therefore the second end of the reversible plate 31 is provided with a sliding extension portion 312 extending downwards. A surface of the sliding extension portion 312 cooperating with the drive block 3211 is an inclined surface. When the handle 7 is pulled, the handle 7 causes the sliding handle member 32 to move along the first sliding slot 41 in a direction away from the connector body 1 and, at the same time, the block 3211 at the upper end face of the sliding handle member 32 slides relative to the inclined surface of the sliding extension portion 312 of the reversible plate 31, so as to cause the reversible plate 31 to turn and bring the first end of the reversible plate 31 to press the second end of the drive arm 23. Optionally, a surface at the first end of the reversible plate 31 and cooperating with the second end of the arm drive 23 is a supported surface 311. The supported surface 311 is arcuate. As a result, an edge of the second end of the drive arm 23 is curved toward the supported surface 311 to form a curved portion. The curved portion is configured to movably engage the supported surface 311.
    A sliding resistance between the first sliding projection 3213 and the first sliding slot 41 is small, so that a small pulling force applied to the handle 7 can cause the sliding handle member 32 to slide. As the sliding handle member 32 slides, the drive block 3211 slides along the inclined surface of the sliding extension portion 312 to cause the reversible plate 31 to rotate. Slip resistance between the drive block 3211 and the inclined surface is low, so that the sliding handle member 32 can easily cause the reversible plate 31 to rotate. The overall movement is fluid and such an operation is convenient and effortless.
    In addition, to ensure fluidity between the drive block 3211 and the inclined surface of the sliding extension portion 312, a portion of the drive block 3211 that contacts the inclined surface is configured to be arc-shaped. In addition, to provide a sliding path of the inclined surface of the sliding extension portion 312 and prevent the drive block 3211 from protruding too far from the sliding handle member 32, a housing slot 3212 is provided on the upper end face of the first portion 321 of the handle slide member and between the drive block 3211 and the second portion 322 of the handle slide member. A lower end of the sliding extension portion 312 is able to extend into the housing slot 3212. In addition, a limiting protrusion protrudes from one side of the handle sliding member 32. The limiting projection may prevent the sliding handle element 32 from being reversed in the frame 4.
    In addition, the handle 7 may be a flexible handle or a hard handle. When the handle 7 is a flexible handle, the handle 7 can only pull the motion conversion assembly 3 to rotate in a direction of pressure of the driving arm 23. When the handle 7 is a hard handle, the handle 7 can not only to pull the motion conversion assembly 3 to rotate in the direction of pressure of the drive arm 23, but may also urge the motion conversion assembly 3 to rotate in a direction opposite to the direction of pressure of the arm Training 23.
    In addition, with reference to Figures 6 and 10 to 12, a mounting base 6 is arranged inside the frame 4 and is configured to connect the connector body 1 and the rear housing 8. A connection part The screw thread is arranged on one end of the mounting base 6 used to connect the rear housing 8. The screw thread connection portion can increase the friction to connect the rear housing 8 and thereby prevent Kevlar fibers in the optical cable 9 are exposed. The frame 4 is configured to detachably enclose the mounting base 6. Optionally, a portion of a bottom of the frame 4 is a movable elastic connection portion 42. A fixing projection 43 is arranged on one side of the movable connection part 42 facing the mounting base 6. A fixing slot corresponding to the fixing projection 43 is arranged on the mounting base 6. When the frame 4 is to be separated from the mounting base 6, the frame 4 can be removed simply by pushing the movable connection portion 42 to cause the attachment projection 43 to disengage from the attachment slot.
    In the present example, the number of connector bodies is two. To ensure that the two connector bodies 1 are arranged side by side and separated, two mounting slots 61 are provided on a first end of the mounting base 6 and each of the connector bodies 1 is detachably mounted in a slot of FIG. correspondingly mounting 61 via a housing 5. More specifically, a first housing part 5 is connected to a second end of the corresponding connector body 1, and a second housing part 5 is detachably connected to the corresponding mounting slot 61. Optionally, each of the two opposite sides of the mounting slot 61 is provided with a second through sliding slot 611, a second sliding projection 51 corresponding to the second sliding slot 611 protrudes from a side of the housing 5. Where a external force is applied, the second sliding projections 51 slide along the second sliding slot 61 to bring the bo Tier 5 to be inserted into the mounting base 6 or be removed therefrom.
    A through hole communicating with the rear housing 8 is arranged on a second end of the mounting base 6. The optical cable 9 passes through the rear housing 8 and then passes through the through hole. Then, a protective envelope of the optical cable 9 is peeled off to expose the optical fibers. The optical fiber passes through the housing 5 and the mounting slot 61 of the mounting base 6, and then enters the interior of the connector body 1. An optical fiber attachment device is arranged inside the body The optical fibers are fixed by the fiber optic attachment apparatus and are then connected to a fiber tip 10.
    When positions of the two connector bodies 1 must be exchanged, firstly, the first end of the reversible plate 31 is disengaged from the second end of the drive arm 23, then the movable connection portion 42 of the frame 4 is pushed, so that the fixing projection 43 is disengaged from the fixing slot, and the frame 4 is removed together with the motion conversion assembly 3. Then, the two housings 5 connected to the connector body 1 are respectively slid out of the mounting slots 61. The positions of the two connector bodies 1 are exchanged, then the two housings 5 connected to the connector bodies 1 whose positions have been exchanged are slid in the respective mounting slots 61; and finally, the frame 4 and the motion conversion assembly 3 are arranged together to enclose the mounting base 6.
    The optical fiber connector provided by this disclosure has multiple advantages, including occupying a small operating space and saving effort when the connector is unlocked from the adapter and being practical when it is in use. an exchange of the positions of the two connector bodies 1.
    The optical fiber connector provided by the present description can be unlocked from the adapter when the handle is pulled. This avoids a case where the locking projection is disengaged from a locking slot only when the drive arm is pressed from the top of the connector, and minimizes an operating space in which the drive arm is squeezed when the connector is inserted or removed so that multiple adapters and / or connectors can be stacked narrower, i.e. the adapters and / or connectors can be mounted at a higher density. In addition, the handle is connected to the drive arm via the motion conversion assembly capable of converting a translation of the handle into rotation of the motion conversion assembly. In operation, when it is just slightly pulled, the handle causes the motion conversion assembly to rotate, so that one end of the motion conversion assembly connected to the drive arm presses on the arm. drive to allow the locking projection to be disengaged from the lock slot. Such an operation is convenient and effortless.
