[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figures 1-5 The wiring harness on the servo motor with auxiliary insulation protection shown includes a fixing plate 1, a storage box 2 installed on the fixing plate 1, multiple housings 5 ​​installed inside the storage box 2, a telescopic component 7 installed inside each housing 5, an insulation component 8 installed on each telescopic component 7, and a wire 4 connected to each insulation component 8. The wire 4 is folded inside the storage box 2, and a cover plate 3 is installed on the storage box 2.

[0025] In practice, the fixing plate 1 is installed on one side of the servo motor. The cable 4, used to connect the servo motor, is inserted from one end of the storage box 2, wound around the various insulating components 8, and then extends out from the other end to connect with the servo motor. The cover plate 3 is then closed. When the servo motor moves and pulls the cable 4 while the device is in operation, the various telescopic components 7 are stretched by the force of the cable 4, allowing the cable 4 to be pulled out of the storage box 2. As the tension on the cable 4 decreases, the cable 4 can be retracted by the tension of the various telescopic components 7. This achieves the storage of the cable 4 while preventing it from becoming too long and drooping, thus avoiding wear and tear. It also prevents the cable from becoming tangled. Furthermore, the connection between the insulating components 8 and the cable 4 prevents the cable 4 from directly contacting the device, thus avoiding the influence of the device's surface current on the cable 4. This ensures stable current and signal transmission for the cable 4, thereby improving the stability of the servo motor's operation.

[0026] The storage box 2 has an inlet at one end and an outlet at the other end, and both the inlet and outlet are fitted with ceramic tubes.

[0027] In specific implementation, the wire body 4 enters the storage box 2 from the ceramic cylinder in the wire inlet and then passes out from the ceramic cylinder in the wire outlet, so that the wire body 4 only contacts the inner wall of the ceramic cylinder, which not only has an insulation effect but also reduces the friction of the wire body 4 due to the smooth surface of the inner wall of the ceramic cylinder.

[0028] One end of the shell 5 is provided with a base 6 which is bolted in the storage box 2.

[0029] The telescopic assembly 7 comprises a fixing block 701, a binding hoop 702, a guide rod 703, a spring 704 and a limiting nut 705, the bottom end of the fixing block 701 is provided with the binding hoop 702 which is sleeved on the insulation assembly 8, the top end of the fixing block 701 is provided with the guide rod 703 which is in sliding connection with the shell 5, the guide rod 703 is sleeved with the spring 704, and the end of the guide rod 703 is provided with the limiting nut 705.

[0030] The guide rod 703 is provided with two guide rods 703 which are arranged in parallel.

[0031] In specific implementation, the spring 704 is supported by the shell 5, so that the spring 704 extrudes the limiting nut 705, the fixing block 701 is pressed against the outer surface of the shell 5, and the arrangement of the two guide rods 703 can ensure that the fixing block 701 vertically rises and avoids rotating, so as to avoid the wire body 4 passing through the bottom insulation assembly 8 from being entangled.

[0032] When the wire body 4 is subjected to a pulling force, the spring 704 is compressed, so that each insulation assembly 8 synchronously approaches, so that the wire body 4 is straightened from the folded state, so that the wire body 4 can be pulled out from the storage box 2 for compensation, and when the pulling force of the wire body 4 is eliminated or reduced, the spring 704 is elongated, and the wire body 4 is automatically pulled into the storage box 2.

[0033] The insulation assembly 8 is made of ceramic material and comprises an insulation ring 801, a wire hole 802 and a binding groove 803, the middle part of the insulation ring 801 is provided with the wire hole 802, and the outer surface of the insulation ring 801 is provided with the binding groove 803.

[0034] In specific implementation, the binding groove 803 is provided to be connected with the binding hoop 702, so as to be fixed at the bottom of the fixing block 701, the wire hole 802 is provided to guide the wire body 4, the insulation ring 801 is made of ceramic material, so as to isolate the wire body 4 and have an insulation effect, the inner wall of the wire hole 802 is smooth, so as to reduce the friction generated when the wire body 4 moves and avoid abrasion.

[0035] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
