Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to an MPO assembly tooling. Background Art

[0002] MPO assembly refers to the process of terminating, testing and equipping a multi-core fiber optic connector (MPO) and an optical cable in a factory. During MPO assembly, an MPO adapter is inserted into an MT sleeve, and the end of the first housing of the MT sleeve is inserted outside the second housing outside the MPO adapter to achieve the mating installation of the MPO adapter and the MT sleeve.

[0003] During the process of MPO assembly, when the MPO adapter and the MT sleeve are inserted, generally, manual assembly is used for installation. However, during the manual assembly process, the force and direction of pushing the housing are not well controlled, resulting in a high defect rate. At the same time, during manual assembly, long-term finger force causes fatigue to the personnel, and calluses form on the fingers, requiring more labor and time to complete the same production tasks, which also leads to an increase in costs. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides an MPO assembly tooling to solve the problems of poor control of the force and direction of pushing the housing during manual assembly and a high defect rate.

[0005] To achieve the above purpose, the basic scheme of the utility model is as follows: an MPO assembly tooling, including a bottom plate, further including:

[0006] A first limiting component capable of limiting the first housing, and the first limiting component is installed on the bottom plate;

[0007] A second limiting component capable of limiting the second housing;

[0008] A sliding component capable of driving the second limiting component to slide towards the first limiting component, and the sliding component is installed on the bottom plate.

[0009] The technical principle of the utility model is as follows: during assembly, the first limiting component can limit the first housing and the MT sleeve, and the second limiting component can limit the second housing and the MPO adapter. At this time, by controlling the sliding component to drive the second limiting component and the MPO adapter to move towards the MT sleeve, the MPO adapter is inserted into the MT sleeve, realizing the accurate relative position and insertion between the MPO adapter and the MT sleeve, accurately controlling the insertion force and direction, and improving the installation yield.

[0010] Further, the first limiting component includes:

[0011] The support block is vertically and detachably installed on the bottom plate. A first limiting groove is horizontally penetrated through the top surface of the support block, and the inner wall of the first limiting groove can abut against the side wall of the MT sleeve.

[0012] The first limiting block is detachably installed on the side of the support block away from the second limiting component. A second limiting groove communicating with the first limiting groove is provided on the first limiting block. The inner wall of the second limiting groove can abut against the side wall of the MT sleeve, and the side wall of the first limiting block close to the support block can abut against the end face at the middle part of the MT sleeve.

[0013] With the above settings, when the MT sleeve is installed at the first limiting groove of the support block and the second limiting groove of the first limiting block, the first limiting groove and the second limiting groove can fully limit the MT sleeve, and the left side wall of the first limiting block can abut against the end face at the middle part of the MT sleeve, realizing the accurate positioning and installation of the MT sleeve.

[0014] Furthermore, the second limiting component includes:

[0015] The limiting block is provided with a third limiting groove;

[0016] The second limiting block is installed on the sliding component. The limiting block is detachably installed on the side wall of the second limiting block close to the first limiting component. The second limiting block is provided with a fourth limiting groove communicating with the third limiting groove; the side wall of the second limiting block close to the limiting block can abut against the middle end face of the MPO adapter, and the side wall of the limiting block close to the first limiting component can abut against the middle end face of the MPO adapter.

[0017] With the above settings, when the MPO adapter is installed at the third limiting groove of the limiting block and the fourth limiting groove of the second limiting block, the middle side wall of the MPO adapter abuts against the side walls of the second limiting block and the limiting block, so that the right end of the MPO adapter is exposed and the middle part is limited, preparing for the assembly between the MPO adapter and the MT sleeve and improving the positioning accuracy of the MPO adapter.

[0018] Furthermore, the sliding component includes:

[0019] The slide rail is horizontally installed on the bottom plate, and the axis of the slide rail is parallel to the horizontal axes of the first limiting groove, the second limiting groove, the third limiting groove and the fourth limiting groove;

[0020] The slider that can slide on the slide rail is detachably connected to the second limiting block.

[0021] With the above settings, the slider cooperates with the guide rail, so that the limiting block and the second limiting block drive the MPO adapter and the optical fiber to move stably and accurately towards the MT sleeve along the guide rail, and the MPO adapter is accurately inserted into the MT sleeve.

[0022] Furthermore, it further includes an optical fiber limiting assembly, and the optical fiber limiting assembly includes:

[0023] An optical fiber limiting block, which is detachably installed on the bottom plate, and the optical fiber limiting block is located on the side of the second limiting assembly away from the first limiting assembly. A first optical fiber limiting groove is horizontally arranged on the optical fiber limiting block, and the first optical fiber limiting groove is coaxially arranged with the fourth limiting groove;

[0024] A cover plate, one side of the cover plate is hinged to the optical fiber limiting block, and a second optical fiber limiting groove that can be aligned and communicated with the first optical fiber limiting groove is arranged on the surface of the cover plate;

[0025] A locking member, which is detachably connected to the cover plate and the optical fiber limiting block, and the locking member is located on the side of the cover plate away from the hinge.

[0026] Through the above settings, the end of the optical fiber is horizontally placed in the first optical fiber limiting groove, the cover plate is flipped so that the second optical fiber limiting groove on the cover plate is buckled to the first optical fiber limiting groove, and the locking member locks the cover plate to the optical fiber limiting block, realizing straightening and limiting of the optical fiber and avoiding the situation of bending of the optical fiber during assembly.

[0027] Furthermore, the optical fiber limiting assembly further includes:

[0028] A plurality of mounting blocks, which are detachably connected to the bottom plate and detachably connected to the side wall of the optical fiber limiting block.

[0029] Through the above settings, the mounting blocks can stably support the optical fiber limiting block, making the limiting of the optical fiber more stable.

[0030] Furthermore, through holes for the slide rail to pass through are horizontally penetrated in the optical fiber limiting block and the support block.

[0031] Through the above settings, the cooperation between the optical fiber limiting block and the support block and the slide rail does not conflict, so that the moving range of the slider between the slide rails is larger, facilitating the control of the horizontal moving range of the MPO adapter.

[0037] As Figure 1 shown, the second limiting component includes a limiting block 40 and a second limiting block 50. A third limiting groove 401 is provided on the limiting block 40. The second limiting block 50 is installed on the sliding component. The limiting block 40 is detachably installed on the right side wall of the second limiting block 50 by screws. A fourth limiting groove 501 communicating with the third limiting groove 401 is provided on the second limiting block 50. The right side wall of the second limiting block 50 can abut against the middle end surface of the MPO adapter 2, and the right side wall of the limiting block 40 can abut against the middle end surface of the MPO adapter 2.

[0038] As Figure 1 shown, the sliding component includes a slide rail 601 and a slider 602 that can slide on the slide rail 601. The slide rail 601 is horizontally installed on the bottom plate 10, and the axis of the slide rail 601 is parallel to the horizontal axes of the first limiting groove 201, the second limiting groove 301, the third limiting groove 401, and the fourth limiting groove 501. The slider 602 is detachably connected to the second limiting block 50 by screws.

[0039] Meanwhile, as Figure 1As shown in the figure, the optical fiber limiting assembly includes an optical fiber limiting block 70, a cover plate 702, a locking member, and two mounting blocks 704. The optical fiber limiting block 70 is detachably mounted on the bottom plate 10 by screws, and the optical fiber limiting block 70 is located on the left side of the second limiting assembly. A first optical fiber limiting groove 701 is horizontally arranged on the optical fiber limiting block 70. The first optical fiber limiting groove 701, the first limiting groove 201, the second limiting groove 301, the third limiting groove 401, and the fourth limiting groove 501 are all coaxially arranged. The upper right side of the cover plate 702 is hinged to the upper right side of the optical fiber limiting block 70, and a second optical fiber limiting groove 703 which can be aligned and communicated with the first optical fiber limiting groove 701 is arranged on the surface of the cover plate 702. The locking member is a pin. A "U" - shaped groove for the pin to be inserted is arranged on the upper side of the cover plate 702. The pin can abut against the upper surface of the cover plate 702, and the pin can be detachably connected to the lower left side of the optical fiber limiting block 70. The mounting block 704 is detachably connected to the bottom plate 10 by screws, and the mounting block 704 is detachably connected to the side wall of the optical fiber limiting block 70 by screws.

[0040] In addition, through - holes 80 for the slide rail 601 to pass through are horizontally penetrated in the optical fiber limiting block 70 and the support block 20.

[0041] When an MPO assembly tooling in this embodiment is in use, the MPO adapter 2 with an optical fiber is installed at the third limiting groove 401 of the limiting block 40 and the fourth limiting groove 501 of the second limiting block 50. The fourth limiting groove 501 can perform initial limiting on the tail of the MPO adapter 2 and the right end of the optical fiber, and the third limiting groove 401 can limit the middle part of the MPO adapter 2. After placing the MPO adapter 2, the side wall of the middle part of the MPO adapter 2 abuts against the right side wall of the second limiting block 50 and the right side wall of the limiting block 40, so that the right end of the MPO adapter 2 is exposed and the middle part is limited, preparing for the assembly between the MPO adapter 2 and the MT sleeve 1. At the same time, the left end of the optical fiber is horizontally placed into the first optical fiber limiting groove 701, the cover plate 702 is flipped, so that the second optical fiber limiting groove 703 on the cover plate 702 is buckled to the first optical fiber limiting groove 701, and the pin is installed on the optical fiber limiting block 70 through the "U" - shaped groove of the cover plate 702 to lock the cover plate 702, thereby straightening and limiting the optical fiber to avoid the optical fiber from being bent.

The first limiting groove 201 and the second limiting groove 301 can fully limit the MT sleeve 1, and the left side wall of the first limiting block 30 can abut against the end face at the middle part of the MT sleeve 1.

[0043] Then, control the slider 602 and the second limit component to move rightward. The cooperation between the slider 602 and the guide rail enables the limit stop 40 and the second limit block 50 to drive the MPO adapter 2 and the optical fiber to move stably and precisely along the guide rail toward the MT sleeve 1, so that the MPO adapter 2 is precisely inserted into the MT sleeve 1. The optical fiber limit component can limit and guide the horizontally moving optical fiber, avoiding the bending of the optical fiber. At the same time, it can prevent the poor assembly caused by the deviation of the force and direction when pushing the MPO adapter 2 during assembly, effectively protecting the safety of the operator and liberating the operator from the cumbersome physical labor.
