An anti-slip wire bundle 602 is fixedly arranged on the inner wall of the upper end of the wire harness positioning sleeve 6.

The diameter of the positioning root base 601 is larger than the diameter of the wire harness positioning sleeve 6. The positioning root base 601 and the wire harness positioning sleeve 6 are of an integral structure.

[0024] Specifically, multiple groups of wire harness positioning sleeves 6 are provided in the terminal fixing port 5. The multiple groups of wire harness positioning sleeves 6 have the same structure, but the diameters of the multiple groups of wire harness positioning sleeves 6 are different. In this way, it is beneficial to adapt to wire harnesses of different diameters and meet the positioning requirements of different wire harness terminals. The protective ring 603 and the anti-slip wire ring 602 are made of the same silicone material. The protective ring 603 is located at the inner middle waist position of the wire harness positioning sleeve 6, and the anti-slip wire ring 602 is located on the upper inner wall of the wire harness positioning ring. The protective ring 603 and the anti-slip wire ring 602 cooperate with each other to protect and position the wire harness, avoiding damage to the wire harness. The receiving foot 604 is used to clamp and position the wire harness passing through the wire harness positioning sleeve 6.
