The adhesive layer 13 bonds the base material layer 12 and the outer protective layer 14 of the PBT material together. The outer protective layer 14 is set as a polyethylene material shell. The outer side of the connector body 1 also includes a side harness assembly 3;

[0026] The side wiring assembly 3 includes an insertion rod 312 fixedly arranged on the outside of the connector body 1, a guide seat 311 is slidingly arranged on the outside of the insertion rod 312, a cross bar 39 is fixedly arranged at the front end of the guide seat 311, a moving block 38 is slidingly arranged on the outside of the cross bar 39, and a vertical rod 37 is fixedly arranged on the top of the moving block 38. The insertion rod 312 serves as a positioning structure to guide the movement of the moving block 38 and maintain stability. The vertical rod 37 is positioned on the outside of the insertion rod 312 and moved to perform wiring operations.

[0027] Specifically, the anti-slip and wear-resistant layer 11 is set to polyethylene-acrylate polymer material, and the base material layer 12 is set to thermoplastic polyester with PBT as the main material, which increases the wear resistance of the connector body 1.
