[0025] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0026] This application discloses an automotive wiring harness terminal crimping device. (Refer to...) Figure 1 and Figure 2 The device includes a base 1, a hydraulic equipment body 2 connected to the upper end of the base 1, a support frame 3 connected to one side of the upper end of the base 1, a crimping seat 4 connected to the bottom inner side of the support frame 3, the crimping seat 4 is used to place the wire harness terminal, a crimping plate 5 connected to the upper inner side of the support frame 3, the crimping plate 5 moves downward under the drive of the hydraulic equipment body 2, and then performs crimping processing on the wire harness terminal, the upper end of the crimping plate 5 is connected to the output rod of the hydraulic equipment body 2, and grooves 6 are opened on both sides of the outer side of the crimping plate 5, and a slider 7 is connected to one side of the inner side of the groove 6.

[0027] Reference Figure 3One end of the slider 7 is connected to the slide plate 8. When the fixing rod 13 is no longer fixed to the slide plate 8, the pressing plate 5 moves downward continuously under the sliding of the slider 7 and the slide plate 8. At this time, the tooth seat 10 no longer moves. Both ends of the slide plate 8 are connected to the inner walls of the slide groove 6. One end of the slide plate 8 is provided with a fixing hole 9. One end of the fixing hole 9 extends through to the outside of the slider 7. One end of the slider 7 is connected to the tooth seat 10. A moving plate 11 is slidably connected to one side of the inside of the tooth seat 10. One end of the moving plate 11 is connected to a magnetic block 12. The other end of the moving plate 11 is connected to a fixing rod 13. One end of the fixing rod 13 extends through to the inside of the fixing hole 9.

[0028] The movable plate 11 has round rods 14 connected to both sides of one end. The movable plate 11 slides along the outside of the round rods 14. With the round rods 14 in place, the movable plate 11 moves in a straight line during movement. One end of the round rods 14 is connected to one side of the gear seat 10, and the other end of the round rods 14 is connected to a support plate 15. One end of the support plate 15 is connected to one side of the inside of the gear seat 10. A spring 16 is sleeved on the outside of the round rods 14. One end of the spring 16 is connected to one side of the movable plate 11. The spring 16 has elastic potential energy. When the magnetic suction plate 26 attracts the magnetic block 12, the movable plate 11 squeezes the spring 16, causing the spring 16 to be compressed. When the magnetic suction plate 26 no longer attracts the magnetic block 12, under the elastic potential energy of the spring 16, it pushes the fixing rod 13 to move into the fixing hole 9, thereby fixing the gear seat 10 and the slide plate 8. The other end of the spring 16 is connected to one side of the support plate 15.

[0029] Reference Figure 4 A rotating shaft 17 is connected to one side of the inside of the crimping seat 4. Mounting plates 18 are rotatably sleeved on both sides of the outside of the rotating shaft 17. One end of the mounting plate 18 is connected to one side of the inside of the crimping seat 4. A first gear 27 is fixedly sleeved on one side of the outside of the rotating shaft 17. The first gear 27 meshes with the gear seat 10. When the gear seat 10 moves downward and contacts the first gear 27, the gear seat 10 drives the first gear 27 to rotate. A second gear 19 is connected to both ends of the rotating shaft 17. The second gear 19 meshes with the gear plate 20 and drives the connecting plate 22 to move. The gear plate 20 is meshed on one side of the second gear 19.

[0030] Among them, the toothed plate 20 has limit rods 21 connected through both sides of one end. The limit rods 21 ensure that the toothed plate 20 moves in a straight line. Both ends of the limit rods 21 are connected to the inner walls of the crimping seat 4. The toothed plate 20 is slidably connected to the limit rods 21. A connecting plate 22 is connected to one side of the upper end of the toothed plate 20. One end of the connecting plate 22 extends through to the top of the crimping seat 4 and is connected to a fixing plate 23. The fixing plate 23 moves towards the center under the push of the toothed plate 20, and then fixes the wire harness terminal externally.

[0031] Reference Figure 5Both sides of the inside of the crimping seat 4 are connected to the plug plate 25. When the tooth seat 10 moves downward, the plug plate 25 moves into the inside of the tooth seat 10. Under the attraction of the magnetic plate 26, it drives the magnetic block 12 to move, which in turn causes the moving plate 11 to drive the fixing rod 13 to move out of the fixing hole 9. One end of the plug plate 25 is fitted with the magnetic plate 26.

[0032] The implementation principle of the automotive wiring harness terminal crimping device according to this application embodiment is as follows: In use, the wiring harness terminal is placed on the upper end of the crimping seat 4. The hydraulic device body 2 drives the crimping plate 5 to move downward. At this time, the fixing rod 13 is located inside the fixing hole 9. The gear seat 10 and the crimping plate 5 are fixedly connected. The downward movement of the crimping plate drives the gear seat 10 to move. When the gear seat 10 moves downward into the crimping seat 4 and contacts the first gear 27, the gear seat 10 drives the first gear 27 to rotate. Under the transmission of the rotating shaft 17, the second gear 19 drives the gear plate 20 to move to one side. The fixing plate 23 moves towards the center under the push of the gear plate 20, thereby fixing the wiring harness terminal externally. To ensure the stability of the toothed plate 20 during the crimping process, while the fixing plate 23 fixes the wire harness terminal, the plug plate 25 moves into the toothed seat 10. Under the attraction of the magnetic suction plate 26, the moving plate 11 drives the fixing rod 13 to move out of the fixing hole 9. At this time, with the setting of the sliding plate 8 and the slider 7, the crimping plate 5 will not move the toothed seat 10 when it moves downward. The crimping plate 5 continues to move downward to crimp the wire harness terminal. When the crimping plate 5 moves upward, the fixing rod 13 moves into the fixing hole 9 under the elastic potential energy of the spring 16. At this time, the toothed seat 10 is fixedly connected to the crimping plate 5, thereby realizing automatic fixing of the wire harness, improving work efficiency and crimping quality.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
