AI Technical Summary
In the prior art, the assembly environment of the rubber parts of the wire harness is highly demanding, and it is difficult to assemble when there is insufficient space. Furthermore, it is difficult to disassemble and repair after assembly.
It adopts a rubber and plastic sheath structure, which includes a combination design of a rubber body and a plastic support body. It achieves sealing and separation through a sheet metal snap-fit structure. Utilizing the sealing function of the outer and inner lips, combined with the positioning of the skeleton snap-fit groove and snap-fit interface, it enables quick assembly and convenient disassembly.
It enables rapid assembly and sealing within a limited space, facilitates subsequent disassembly and maintenance, effectively isolates dry and wet areas, and improves assembly efficiency and maintainability.
