[0020] In summary, the present application has at least one of the following beneficial technical effects:
[0021] 1. This application utilizes the cooperative arrangement of structures such as through slots, bidirectional screws, and clamping plates. In use, the copper wire bundle is first inserted into the clamping port. Then, the bidirectional screw is rotated by the rotating disk, causing the bidirectional screw to drive the two clamping plates closer together. This clamps the copper wire bundle tightly and secures it, preventing it from coming off the clamping port. This minimizes the possibility that the copper wire bundle of the wheel speed sensor might loosen from the clamping port due to prolonged bumpy operation, leading to poor contact.
[0022] 2. By pulling the pawl and engaging the ratchet with the spring, the rotating disk can only rotate in one direction. This allows the two clamping plates to come close together and clamp the copper wire bundle tightly, preventing it from rotating back and avoiding loosening of the clamping plates. To disassemble, simply move the pawl to disengage from the ratchet and the rotating disk can be rotated in the opposite direction. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0029] This application discloses a wheel speed sensor anti-detachment terminal.
[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A wheel speed sensor anti-detachment terminal includes a frame 1, a partition plate 2 fixedly connected inside the frame 1, two guide blocks 3 inside the frame 1, one end of the guide block 3 extending out of the frame 1, and the other end of the guide block 3 having a clamping port 4 for inserting copper wire harnesses. The partition plate 2 is provided with an anti-detachment component to prevent the copper wire harnesses from loosening. The anti-detachment component includes a through groove 5, a bidirectional screw 6, a rotating disk 7, and a clamping plate 8.
[0031] The through groove 5 is opened on the side wall of the partition plate 2 near the wire clamping port 4. The bidirectional screw 6 is vertically installed in the through groove 5. The bottom end of the bidirectional screw 6 is rotatably connected to the frame 1, and the top end of the bidirectional screw 6 passes through the frame 1 and is fixedly connected to the rotating disk 7. Two clamping plates 8 are provided and are slidably installed in the through groove 5. The clamping plates 8 are both sleeved on the bidirectional screw 6 and form a threaded connection. Both ends of the clamping plates 8 extend to both sides of the partition plate 2 to clamp the copper wire bundle.
[0032] Reference Figure 1 and Figure 2 Two mounting holes 9 are provided on the upper surface of the frame 1. An elastic abutment 10 for fixing the guide block 3 inside the frame 1 is fixedly connected to one side wall of the mounting hole 9. By inserting the guide block 3 into the frame 1 and then abutting the guide block 3 with the elastic abutment 10, the guide block 3 can be fixed to prevent it from falling off the frame 1, and at the same time, it is convenient to disassemble.
[0033] Reference Figure 1 and Figure 2 The upper and lower side walls inside the frame 1 are provided with receiving grooves 11 that are connected to the through groove 5. The receiving grooves 11 are adapted to the clamping plate 8. The clamping plate 8 can be hidden through the receiving grooves 11 to prevent the clamping plate 8 from blocking when the guide block 3 is disassembled or installed.
[0034] Reference Figure 1 The upper surface of the frame 1 is provided with a U-shaped block 12. The two ends of the U-shaped block 12 are fixedly connected to the elastic abutment block 10 respectively. The elastic abutment block 10 can be easily pulled by the U-shaped block 12 to disassemble the guide block 3.
[0035] Reference Figure 4 Both ends of the opposite sidewalls of the two clamping plates 8 are fixedly connected with elastic rubber pads 13. The elastic rubber pads 13 can prevent the clamping plates 8 from directly contacting the copper wire harness, thereby reducing the damage to the copper wire harness.
[0036] Reference Figure 1 and Figure 4 A guide rod 14 is provided on one side of the bidirectional screw 6. The two ends of the guide rod 14 are fixedly connected to the frame 1. Two clamping plates 8 are sleeved on the guide rod 14. The guide rod 14 can improve the stability of the two clamping plates 8 when they move.
[0037] Reference Figure 3A ratchet 15 is fixedly connected to the rotating disk 7. A mounting rod 16 is fixedly connected to the upper surface of the frame 1. A pawl 17 is rotatably connected to the mounting rod 16. The pawl 17 engages with the ratchet 15. A fixing rod 18 is fixedly connected to one side of the mounting rod 16 on the upper surface of the frame 1. A spring 19 is fixedly connected between the fixing rod 18 and the pawl 17 to prevent the pawl 17 from disengaging from the ratchet 15. By pulling the pawl 17 to engage with the ratchet 15 through the spring 19, the rotating disk 7 can only rotate in one direction. This allows the two clamping plates 8 to come close to each other and clamp the copper wire bundle so that it cannot rotate back, thus preventing the clamping plates 8 from becoming loose. Disassembly allows the pawl 17 to disengage from the ratchet 15, enabling the rotating disk 7 to rotate in the opposite direction.
[0038] The implementation principle of the anti-detachment terminal of the wheel speed sensor in this embodiment is as follows: In use, the user first inserts the guide block 3 into the frame 1, and the guide block 3 is fixed by the elastic abutment block 10 to prevent the guide block 3 from detaching from the frame 1. Then, the copper wire bundle is inserted into the clamping port 4. The spring 19 pulls the pawl 17 to engage with the ratchet 15, so that the rotating disk 7 can only rotate in one direction. This drives the bidirectional screw 6 to rotate clockwise, so that the two clamping plates 8 move closer to each other and clamp the copper wire bundle tightly so that it cannot rotate back. This prevents the rotating disk 7 from rotating back and causing the clamping plates 8 to loosen, thus preventing the copper wire bundle from detaching from the clamping port 4. This minimizes the problem that the copper wire bundle of the wheel speed sensor may loosen from the clamping port 4 due to long-term bumpy conditions, resulting in poor contact.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
