Expandable Wire Harness Seal Protector for Vehicles

Abstract

The invention discloses an expandable wiring harness sealing protective cover for vehicles, which is characterized in that it comprises a coaxial stem and a sealing connection ring, the stem is located at the center of the sealing ring, the stem and the sealing connection ring are connected by an annular film, and the stem The axis position is provided with an axial main wire hole, and the inner wall of the main wire hole is provided with a ring-shaped wavy protrusion. The side of the core column is provided with a side column that is coaxial with it and connected to it and passes through the annular film. There is a tapered hole coaxial with it on the column. The large end of the tapered hole is opened on one end surface of the side column. The tip of the tapered hole is 0.1mm to 1mm away from the other end surface of the side column. There is a distance between the crossing point and the original vehicle wiring harness, which can avoid the problems of poor heat dissipation and electromagnetic compatibility caused by the close contact between the new wiring harness and the original vehicle wiring harness at the sealing sleeve, and save time and effort when upgrading.

Description

technical field [0001] The invention relates to a component for automobile assembly, in particular to an expandable wire harness sealing protective cover for automobiles. Background technique [0002] China is a big country in the automobile industry and also a big consumer of automobiles. The number of automobiles is increasing day by day, and automobiles have become an indispensable tool for the public. In order to meet some special needs of drivers, it is often inevitable to upgrade vehicles during their service life. Such as the installation of anti-theft system, car warming system, panoramic system, smart key system and other equipment, in the process of such upgrading and transformation, it is usually accompanied by the transformation of the electrical part, and new electrical lines need to be added. These new electrical lines are generally It is necessary to pass through the car body from one space to another space. The existing wiring methods generally make holes in ...

[0002] China is a big country in the auto industry and a big car consumer. The number of cars is increasing day by day. Cars have become an indispensable tool for the public. In order to meet the special needs of drivers, it is often necessary to upgrade the vehicles during their service life. Such as the installation of anti-theft system, car heating system, panorama system, smart key system and other equipment, this kind of upgrading and transformation process is usually accompanied by the transformation of the electrical part, and new electrical circuits need to be added. These newly added electrical circuits are generally It is necessary to pass through the car body from one space to another space. The existing wiring methods are generally to punch holes in the car body or route along the original car wiring harness. These two methods have certain disadvantages. Holes will inevitably affect the structure of the car body and bring potential safety hazards. When routing along the original car wiring harness, the original car wiring harness is connected to the car body through the matching sealing sleeve. It is necessary to expand the sealing sleeve to pass the new wire through. It is easy to damage the sealing sleeve, which will affect the airtightness of the car body, and the contact between the newly added wiring harness and the original vehicle wiring harness at the sealing sleeve is too close. The electromagnetic interference of the vehicle will affect the electromagnetic compatibility of the vehicle. Both methods are time-consuming and labor-intensive in the upgrade and transformation, and still need to be solved technically.
