Description
Technical Field
[0001] This utility model relates to the field of optical module technology, specifically to an MT clip and MT head assembly fixture. Background Technology
[0002] During the production of optical modules, without tooling, when assembling the MT clip and MT head, the worker has to hold the MT head with one hand and the MT clip with the other, pressing them against each other to make the upper and lower clip plates of the MT clip lock onto the outside of the card in the MT head. This operation is very laborious, and the MT clip may not be assembled properly, resulting in a decrease in product yield. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an MT buckle and MT head assembly fixture to overcome the shortcomings of the prior art.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An assembly fixture for an MT buckle and an MT head includes: a base plate, a buckle seat, and a push plate. The push plate is disposed on the upper surface of the base plate. The buckle seat is slidably disposed on the upper surface of the base plate and moves closer to and further away from the push plate during sliding along a straight line. The push plate is provided with a first assembly hole for installing the MT head. The push plate is provided with clearance openings above and below the first assembly hole for the upper and lower buckle plates of the MT buckle to enter. The buckle seat is provided with a second assembly hole for installing the MT buckle at a position corresponding to the first assembly hole.
[0005] The beneficial effects of this utility model are as follows: When assembling the MT buckle and MT head, the MT head is installed in the first assembly hole on the push plate, and the MT buckle is installed in the second assembly hole on the buckle seat. At this time, the MT head faces the area between the upper and lower buckle plates in the MT buckle. Then, the buckle seat is pushed to move towards the push plate. The upper and lower buckle plates of the MT buckle are initially locked onto the MT head and enter the two clearance slots. The buckle seat is then pushed to move towards the push plate, and finally, the upper and lower buckle plates of the MT buckle are locked onto the outside of the card in the MT head, thereby completing the assembly between the MT buckle and the MT head. This tooling can ensure that the MT buckle and the MT head are properly assembled, improve the product yield, and also save physical strength for the workers.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, a linear guide rail is provided on the upper surface of the base plate, and the buckle seat is located on the slider of the linear guide rail.
[0008] The further beneficial effect of adopting the above is that by mounting the buckle seat on the slider of the linear guide, it can be ensured that the buckle seat always moves in a straight line, so as to avoid misalignment between the MT buckle and the MT head.
[0009] Furthermore, a recessed cavity is formed on the upper surface of the base plate, and the linear guide rail is located in the recessed cavity on the base plate.
[0010] Furthermore, a mounting base is provided on the upper surface of the base plate, and the push plate is mounted on the mounting base.
[0011] Furthermore, an assembly groove is formed on the upper surface of the mounting base, the assembly groove extends through the side of the mounting base near the buckle seat, an elastic mechanism is provided in the assembly groove, a push plate is provided on the elastic mechanism, and the moving direction of the push plate on the elastic mechanism is the same as the moving direction of the buckle seat.
[0012] The further beneficial effect of adopting the above is that when the buckle seat is pushed to move towards the push plate, the MT buckle and the MT head are in elastic contact.
[0013] Furthermore, the elastic mechanism includes two locking screws and two first springs. Each end of the push plate has a through hole along its moving direction. The screw end of each locking screw passes through a through hole in the push plate and is threaded to the mounting base. The two first springs are respectively fitted on the two locking screws, and the two ends of each first spring abut against the side wall of the mounting groove and the push plate.
[0014] The further beneficial effects of the above are as follows: when the buckle seat is pushed to move towards the push plate, the upper and lower buckle plates of the MT buckle first contact the MT head, and then the push plate is moved along the two plug screws, while the two first springs are compressed and deformed. When the two first springs are no longer compressed, the buckle seat is pushed to finally make the upper and lower buckle plates of the MT buckle lock into the outside of the card in the MT head, thereby completing the assembly between the MT buckle and the MT head. The assembled MT buckle and MT head are removed, and the push plate is pushed back to its original position by the elastic force of the first spring.
[0015] Furthermore, two hooks are arranged on the side of the push plate away from the buckle seat above the mounting base. The middle of each hook is rotatably connected to the mounting base. The two hooks are located at the two ends of the push plate. On the upper surface of the push plate, there is a card plate at each end that cooperates with the hook. A guide surface that slopes upwards is provided on the side of the card plate near the hook.
[0016] The further beneficial effects of the above are as follows: when assembling the MT buckle and the MT head, the push plate is locked by the action of the hook and the plate. Then, the assembled MT buckle and MT head are removed, and the hook is pressed to release the hook and the plate. The push plate is then pushed back to its original position by the elastic force of the first spring.
[0017] Furthermore, each hook has a second spring installed below the end furthest from the card plate, with the two ends of the second spring abutting against the mounting base and the hook, respectively.
[0018] The further beneficial effect of adopting the above is that by using the second spring to press against the hook, the hook can be stably engaged with the plate.
[0019] Furthermore, the first mounting hole penetrates both sides of the push plate in the moving direction, and the upper clearance hole of the two clearance holes penetrates the upper surface of the push plate. The mounting base has two limiting plates that abut against the MT head on the side of the push plate away from the buckle seat, and the push plate has a clearance hole at each corresponding limiting plate.
[0020] The further beneficial effects of the above are as follows: when the push buckle seat moves towards the push plate, the upper and lower buckle plates of the MT buckle first contact the MT head, and then the push plate moves along the two plug screws, while the two first springs are compressed and deformed. At this time, the MT head in the push plate remains in its original position under the restriction of the two limit plates. During the process of the push plate compressing the first spring, the limit plate will enter the clearance hole of the push plate to ensure that the MT buckle and the MT head are assembled.
[0021] Furthermore, the base plate is made of stainless steel, and the push plate is made of aluminum alloy. Attached Figure Description

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0025] Example 1 like Figures 1 to 7 As shown, an MT buckle and MT head assembly fixture includes: a base plate 1, a buckle seat 2, and a push plate 3. The push plate 3 is disposed on the upper surface of the base plate 1, while the buckle seat 2 is slidably disposed on the upper surface of the base plate 1 and can move closer to and further away from the push plate 3 during linear sliding. The push plate 3 has a first assembly hole 310 for installing the MT head 10, that is, the MT head 10 is subsequently installed in the first assembly hole 310 on the push plate 3. The push plate 3 has upper and lower buckle plates 91 for the MT buckle 9 above and below the first assembly hole 310, respectively. The clearance opening 340 is larger than the width of the buckle plate 910. When the MT head 10 is installed in the first mounting hole 310 on the push plate 3, the two clearance openings 340 are located above and below the MT head 10 respectively. The buckle base 2 has a second mounting hole 210 for installing the MT buckle 9 at the position corresponding to the first mounting hole 310. That is, the MT buckle 9 is subsequently installed in the second mounting hole 210 on the buckle base 2. The MT buckle 9 and the MT head 10 are both existing technologies, and their structures have not been improved here. When assembling the MT clip 9 and MT head 10, the MT head 10 is installed in the first assembly hole 310 on the push plate 3, and the MT clip 9 is installed in the second assembly hole 210 on the clip seat 2. At this time, the MT head 10 is facing the area between the upper and lower clip plates 910 in the MT clip 9. Then, the clip seat 2 is pushed to move towards the push plate 3. The upper and lower clip plates 910 of the MT clip 9 are initially clipped onto the MT head 10 and enter the two clearance slots 340. The clip seat 2 is pushed to move towards the push plate 3, and finally the upper and lower clip plates 910 of the MT clip 9 are clipped onto the outside of the clip in the MT head 10, thereby completing the assembly between the MT clip 9 and the MT head 10. This tooling can ensure that the MT clip 9 and the MT head 10 are properly assembled, improve the product yield, and also save the labor of the workers.
[0026] Example 2 like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: A linear guide rail 4 is provided on the upper surface of the base plate 1, and the buckle seat 2 is provided on the slider of the linear guide rail 4. The buckle seat 2 and the slider on the linear guide rail 4 can be connected by screws. By mounting the buckle seat 2 on the slider of the linear guide rail 4, it can be ensured that the buckle seat 2 always moves in a straight line to avoid misalignment between the MT buckle 9 and the MT head 10. Of course, the linear guide rail 4 here is only an exemplary description. In actual application, other methods are not excluded. For example, a dovetail groove is opened on the base plate 1, and a dovetail block is provided on the lower surface of the buckle seat 2. The dovetail block on the lower surface of the buckle seat 2 is located in the dovetail groove opened on the base plate 1 to realize the sliding connection between the buckle seat 2 and the base plate 1. This method can still ensure that the buckle seat 2 always moves in a straight line.
[0027] Furthermore, a recess 110 is formed on the upper surface of the base plate 1, and the linear guide rail 4 is located in the recess 110 on the base plate 1, which can reduce the height of the buckle seat 2 on the base plate 1.
[0028] Example 3 like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below: A mounting base 5 is provided on the upper surface of the base plate 1, and the push plate 3 is placed on the mounting base 5. The PCB board of the module can be placed on the mounting base 5.
[0029] Example 4 like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 3, as detailed below: An assembly groove 510 is formed on the upper surface of the mounting base 5. The assembly groove 510 passes through the side of the mounting base 5 near the buckle seat 2. An elastic mechanism 6 is provided in the assembly groove 510. The push plate 3 is located on the elastic mechanism 6. The moving direction of the push plate 3 on the elastic mechanism 6 is the same as the moving direction of the buckle seat 2. When the buckle seat 2 is pushed to move towards the push plate 3, the MT buckle 9 and the MT head 10 are in elastic contact.
[0030] Example 5 like Figures 1-5 As shown, this embodiment is a further improvement on embodiment 4, as detailed below: The elastic mechanism 6 includes two locking screws 610 and two first springs 620. A through hole 320 is formed at each end of the push plate 3 along its moving direction. The screw end of each locking screw 610 passes through a through hole 320 on the push plate 3 and is threadedly connected to the mounting base 5. The outer diameter of the locking screw 610 nut is larger than the inner diameter of the through hole 320. The two first springs 620 are respectively fitted onto the two locking screws 610, and both ends of each first spring 620 abut against the mounting groove 51. When the push plate 3 is pushed to move the buckle seat 2 towards the push plate 3, the upper and lower buckle plates 910 of the MT buckle 9 first contact the MT head 10, and then push the push plate 3 along the two plug screws 610, while the two first springs 620 are compressed and deformed. When the two first springs 620 are no longer compressed, the buckle seat 2 is pushed to finally make the upper and lower buckle plates 910 of the MT buckle 9 lock on the outside of the card in the MT head 10, thereby completing the assembly between the MT buckle 9 and the MT head 10.
[0031] Furthermore, two hooks 7 are arranged on the side of the push plate 3 away from the buckle seat 2 above the mounting base 5. The middle of each hook 7 is rotatably connected to the mounting base 5. For example, the middle of each hook 7 is rotatably connected to the mounting base 5 through a rotating shaft. Here, we only introduce a common rotating connection structure. The rotation axis of each hook 7 around the rotating connection point is perpendicular to the moving direction of the buckle seat 2. The two hooks 7 are located at the two ends of the push plate 3, and a buckle plate 330 that cooperates with the hook 7 is provided at each of the two ends on the upper surface of the push plate 3. The buckle plate 330 has a guide surface 331 that slopes upward from the bottom on the side near the hook 7. When the push plate 3 moves toward the hook 7, the hook 7 can first contact the guide surface 331 of the buckle plate 330, thereby guiding the hook 7 to engage with the buckle plate 330. When the buckle seat 2 is pushed to move towards the push plate 3, the MT buckle 9 first contacts the MT head 10, and then pushes the push plate 3 along the two locking screws 610, while simultaneously compressing and deforming the two first springs 620. When the two first springs 620 are no longer compressed and the two hooks 7 are fastened on the two locking plates 330, the buckle seat 2 is pushed further to finally make the upper and lower buckle plates 910 of the MT buckle 9 lock on the outside of the card in the MT head 10, thus completing the assembly between the MT buckle 9 and the MT head 10. At this time, the push plate 3 is locked by the cooperation of the hooks 7 and the locking plates 330. Then, the assembled MT buckle 9 and MT head 10 are removed, and the hooks 7 are pressed to release the hooks 7 from the locking plates 330. The push plate 3 is then pushed back to its original position by the elastic force of the first springs 620.
[0032] Each hook 7 has a second spring 8 installed below the end furthest from the plate 330. The two ends of the second spring 8 abut against the mounting base 5 and the hook 7 respectively. By the second spring 8 pressing against the hook 7, the hook 7 can be stably engaged with the plate 330.
[0033] Example 6 like Figures 1-5 As shown, this embodiment is a further improvement on embodiment 5, as detailed below: The first mounting hole 310 penetrates both sides of the push plate 3 in the moving direction. The upper clearance opening 340 of the two clearance openings 340 penetrates the upper surface of the push plate 3. The mounting base 5 has two limiting plates 520 on the side of the push plate 3 away from the buckle seat 2, which abut against the MT head 10. The limiting plate 520 has an inverted L-shaped structure. The push plate 3 has a clearance hole 350 at each corresponding limiting plate 520. When the buckle seat 2 is pushed to move towards the push plate 3, the upper and lower buckle plates 910 of the MT buckle 9 first contact the MT head 10, and then push the push plate 3 along the two plug screws 610, while the two first springs 620 are compressed and deformed. At this time, the MT head 10 in the push plate 3 remains in its original position under the restriction of the two limiting plates 520. During the process of the push plate 3 compressing the first spring 620, the limiting plate 520 will enter the clearance hole 350 of the push plate 3 so that the push plate 3 can compress the first spring 620.
[0034] Example 7 like Figures 1-5 As shown, this embodiment is a further improvement on any one of embodiments 1 to 6, as detailed below: The base plate 1 is preferably made of stainless steel, such as 304 stainless steel, and the push plate 3 is preferably made of aluminum alloy. Of course, this is just an example, and other materials are not excluded in actual application.
[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
