Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a rubber sleeve for a wiring harness of an automobile door. Background Art

[0002] The wiring harness rubber sleeve is a molded rubber product that is wrapped around the wiring harness and used to protect the wiring harness from wear when the wiring harness passes through the sheet metal. The car hatchback door is generally connected to the car body with an inward hinge. The rubber sleeve does not expand or contract much during the opening and closing of the hatchback door. However, as people's demand for cars increases, the hatchback door and the car body are mostly connected with outward hinges, so that the hatchback door can rotate a large angle along the axis of the outward hinge to increase the aesthetics and comfort of the car. However, the wiring harness has a large expansion and contraction amount, and the length of the rubber sleeve needs to be lengthened accordingly. Due to the excessive length of the rubber sleeve, the uncertainty of the expansion and contraction state of the rubber sleeve after the door is closed is increased, which easily causes deformation and interference of the rubber sleeve, resulting in the wiring harness being squeezed by the car body sheet metal, causing problems such as wire breakage. The patent publication number is CN210852331U, and the patent name is "A kind of automobile door wiring harness rubber sleeve and automobile hatchback door structure". In the disclosed technical solution, a limiting structure is arranged on the telescopic section, and the limiting structure abuts against the vehicle body during the final stage of the door closing process, so as to facilitate the telescopic section to extend and retract along its axial direction, thus solving the above-mentioned technical problems. However, the telescopic section is a corrugated sleeve, which makes it inconvenient to quickly install the limiting structure into place. Utility Model Content
