Problems solved by technology

However, when making threads, it is necessary to expand the rubber parts with expansion pliers first, and then pass the threads through the expanded rubber parts one by one. This way of making threads is labor-intensive and the thread-making efficiency is low.
[0004] In order to reduce the installation time of the wire harness to the rubber part, an open rubber part that can be directly released when making the wire without expansion is required. The opening structure of the rubber part generally designed is a linear opening, which is difficult to achieve. The sealing of the rubber parts is waterproof, and when making wire wrapping tape, the wire harness is easy to come out of the rubber parts, making it more inconvenient to make wires

Abstract

The invention relates to a sealing opening structure for a two-sheet type rubber piece. The rubber piece comprises an outer rubber piece body, an inner rubber piece body and a plastic support. The plastic support is assembled on the outer rubber piece body, and the inner rubber piece body is inserted in the outer rubber piece body. The inner rubber piece body is provided with a tooth-shaped opening used for preventing a wire harness from disengaging from the opening position during wire making. Compared with the prior art, the sealing opening structure has the beneficial effects that reliability is high, waterproof performance is good, and cost is reduced.

Description

technical field [0001] The invention relates to a threading rubber part, in particular to a sealing opening structure for a two-piece rubber part. Background technique [0002] Chinese patent CN 201858435 U discloses a rubber part for wire harness, which includes an inlet pipe body and an outlet pipe body for threading the wire harness, and a rubber body adapted to the body assembly hole outside the inlet pipe body and the outlet pipe body; The rubber body is in the shape of a bladder with a cavity. A sealing groove is provided at the position where the rubber body adapts to the flanging of the assembly hole of the vehicle body. The rubber body is adapted to be provided with an annular groove on the outer circumference of the outlet pipe. Reinforcing ribs are also arranged on the rubber body. Since the rubber part for the wiring harness adopts a bladder-shaped rubber body and is provided with a sealing groove, the cavity of the rubber part can effectively absorb shock and...
