Waterproof wire harness sheath of easy fixing type

Abstract

The invention discloses a waterproof wire harness sheath of an easy fixing type, and the sheath comprises a sheath body which is provided with a terminal connection part. The interior of the sheath body is provided with a waterproof protection ring, and the waterproof protection ring is disposed outside the terminal connection part in a peripheral winding manner along terminal connection part. Thewall surface of the top of the sheath body is provided with two inverted L shaped convex blocks, wherein the vertical edges of the two inverted L shaped convex blocks are symmetric, and the lateral edges of the two inverted L shaped convex blocks extend oppositely. Compared with the prior art, the sheath employs the waterproof protection ring, so the water is not liable to enter the wire harnesssheath due to the blocking effect of the waterproof protection ring when the water round the wire harness sheath is sprayed to the wire harness sheath, and also can avoid a short circuit fault of a wire harness. Meanwhile, the two inverted L shaped convex blocks form a clamping slot, so the sheath can be fixed on other parts through a buckle or a support, and is effectively prevented from fallingin a high-frequency vibration environment.

Description

technical field [0001] The invention relates to a wire harness sheath, in particular to an easily fixed waterproof wire harness sheath. Background technique [0002] Automotive wiring harness sheaths are scattered throughout the entire space of the car, from the cab, door, to the chassis, cargo box, etc. If the automotive wiring harness is the blood system of the vehicle, then the sheath is the joints of the vehicle, connecting different parts , Different circuits are connected, so that information can be exchanged between the various components of the vehicle and become an organic whole. [0003] When matching the vehicle harness sheath, in addition to considering the use area of ​​the sheath and load electrical appliances, while ensuring excellent reliability and waterproofness, it is also necessary to take into account the fixing measures. For example, in the chassis area, the environment is relatively harsh, rain, sand and high-frequency vibration are severe tests for t...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the sheaths on the car are plugged with the sheath on the branch of the wiring harness of the component, and there is no fixing method itself. On roads and parts, such fixing measures are unreliable, because the environment used by cars is relatively harsh, and they often face adverse conditions such as high-frequency vibration and high temperature. , broken, causing car failure, and even fire and other personal safety hazards
