It is aligned with the crimping groove to crimp the terminal and prevent the terminal from falling off. It is easy to use. However, the fastening nut needs to be manually rotated to tighten and loosen. If the equipment needs to frequently replace the crimping block, repeatedly tightening the nut will take up a lot of time and effort. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: A terminal crimping device, comprising: The base has a lower mold connected to the top center, and a pressure groove is formed on the top of the lower mold. A support frame is connected to the top of the base, and an electric push rod is connected to the top of the support frame. One end of the output shaft of the electric push rod passes through the top of the support frame and is connected to a housing. A pair of first strip-shaped holes are symmetrically formed on the bottom of the housing. A protruding plate is slidably connected inside the first strip-shaped hole. A pressure block is fixedly connected to the bottom of the protruding plate.

[0005] In one possible implementation, the positioning mechanism includes a side plate, the bottom of which is fixedly connected to the outer shell. A second circular hole is provided inside the side plate, and a positioning rod is slidably connected inside the second circular hole. One end of the positioning rod extends into the interior of the first circular hole, and the other end of the positioning rod is connected to an arc-shaped block. A return spring is sleeved on the outside of the positioning rod, one end of which is fixedly connected to the arc-shaped block, and the other end of which is fixedly connected to the side plate.

[0006] In one possible implementation, a second strip-shaped hole is provided on the left side of the housing, and a screw hole is provided on the right side of the housing. A screw rod is threaded into the screw hole, a knob is connected to one end of the screw rod, and a bearing seat is rotatably connected to the other end of the screw rod. A drive plate is fixedly connected to the outside of the bearing seat, and the left side of the drive plate is slidably connected to the second strip-shaped hole.

[0007] In one possible implementation, the drive board has two pairs of first slots and second slots symmetrically opened on its front and rear sides, with the position of the first slots corresponding to the position of the arc-shaped block.

[0008] In one possible implementation, the inner walls of both the first card slot and the second card slot are provided with rounded corners.

[0009] In one possible implementation, both the first card slot and the second card slot are configured as isosceles trapezoids, and the depth of the second card slot is greater than the depth of the first card slot.

[0010] In one possible implementation, a polytetrafluoroethylene (PTFE) wear-resistant sleeve is connected to the outer side of the arc-shaped block, and the outer wall of the PTFE wear-resistant sleeve is slidably connected to the first slot and the second slot.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By rotating the knob, the drive plate inside the housing slides forward in cooperation with the screw hole, screw, and bearing seat. At the same time, the sliding action of the first slot and the arc block facilitates the sliding of the arc block into the second slot. Then, the elastic reset effect of the return spring causes the arc block to slide backward, and the end of the positioning rod slides out from the protrusion plate, making it easy to remove the pressure block. The reverse operation can also quickly lock it during installation. This operation does not require multiple turns of turning, which can significantly shorten the single disassembly and assembly time, improve disassembly and assembly efficiency, and adapt to batch model change requirements.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This application provides a terminal crimping device to solve the problems in the prior art.

[0017] The technical solution in this application is to solve the above problems, and the overall approach is as follows: like Figures 1-4 As shown, a terminal crimping device includes: The base 6 has a lower mold 8 connected to the top center. The lower mold 8 has a pressure groove 7 on its top. The base 6 has a support frame 5 connected to its top. The support frame 5 has an electric push rod 1 connected to its top. One end of the output shaft of the electric push rod 1 passes through the top of the support frame 5 and is connected to the outer shell 2. The bottom of the outer shell 2 has a pair of first strip holes 20 symmetrically opened on the left and right sides. The first strip holes 20 have a slidably connected convex plate 9 inside. The bottom of the convex plate 9 has a pressure block 4 fixedly connected to it. The convex plate 9 has a second round hole 22 inside. The second round hole 22 has a positioning mechanism inside.

[0018] In some examples, the positioning mechanism includes a side plate 10, the bottom of which is fixedly connected to the outer shell 2. A second circular hole 22 is provided inside the side plate 10, and a positioning rod 16 is slidably connected inside the second circular hole 22. One end of the positioning rod 16 extends into the interior of the first circular hole 21, and the other end of the positioning rod 16 is connected to an arc-shaped block 24. A return spring 11 is sleeved on the outside of the positioning rod 16. One end of the return spring 11 is fixedly connected to the arc-shaped block 24, and the other end of the return spring 11 is fixedly connected to the side plate 10. When the drive plate 15 slides forward, the arc-shaped block 24 is easily slid into the interior of the second slot 18 under the sliding action of the first slot 17 and the arc-shaped block 24. Then, the elastic return effect of the return spring 11 causes the arc-shaped block 24 to slide backward, and at the same time, the end of the positioning rod 16 slides out from the protrusion 9.

[0019] In some examples, a second strip-shaped hole 23 is provided on the left side of the outer casing 2, and a screw hole 19 is provided on the right side of the outer casing 2. A screw rod 13 is threadedly connected to the inside of the screw hole 19. A knob 3 is connected to one end of the screw rod 13, and a bearing seat 12 is rotatably connected to the other end of the screw rod 13. A drive plate 15 is fixedly connected to the outside of the bearing seat 12. The left side of the drive plate 15 is slidably connected to the second strip-shaped hole 23. By rotating the knob 3, the drive plate 15 inside the outer casing 2 is driven to slide forward or backward in cooperation with the screw hole 19, the screw rod 13 and the bearing seat 12.

[0020] In some examples, the drive board 15 has two pairs of first slots 17 and second slots 18 symmetrically opened on the front and rear sides. The position of the first slot 17 corresponds to the position of the arc block 24. In the locked state, the arc block 24 slides into the interior of the first slot 17. When disassembly is required, the disassembly can be completed by smoothly sliding the arc block 24 from the first slot 17 into the second slot 18.

[0021] In some examples, the inner walls of the first slot 17 and the second slot 18 are provided with rounded corners to facilitate the smooth sliding of the arc block 24 back and forth within the first slot 17 and the second slot 18.

[0022] In some examples, both the first card slot 17 and the second card slot 18 are set to an isosceles trapezoidal shape, and the depth of the second card slot 18 is greater than the depth of the first card slot 17.

[0023] In some examples, the outer side of the arc-shaped block 24 is connected to a polytetrafluoroethylene (PTFE) wear-resistant sleeve 14. The outer wall of the PTFE wear-resistant sleeve 14 is slidably connected to the first slot 17 and the second slot 18. The PTFE wear-resistant sleeve 14 on the outer side of the arc-shaped block 24 can reduce sliding wear with the slots. The rounded corner design of the first slot 17 and the second slot 18 can prevent jamming during sliding and further ensure smooth operation.

[0024] This invention uses a rotating knob 3 to drive the drive plate 15 inside the housing 2 to slide forward in cooperation with the screw hole 19, screw 13, and bearing seat 12. At the same time, the sliding action of the first slot 17 and the arc block 24 facilitates the sliding of the arc block 24 into the second slot 18. Then, the elastic reset effect of the return spring 11 causes the arc block 24 to slide backward, and at the same time, the end of the positioning rod 16 slides out from the protrusion 9, which facilitates the disassembly of the pressure block 4. The reverse operation can also quickly lock the device during installation. This operation does not require multiple turns of the knob, which can significantly shorten the disassembly and assembly time, improve the disassembly and assembly efficiency, and adapt to the needs of batch model changeover.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
