Expansible protective sleeve with arched positioning terminals

Abstract

The invention discloses an expansible protective sleeve with arched positioning terminals. The protective sleeve is characterized by comprising coaxial core tubes, a sealing connection ring and binding posts, the core tubes are placed at the center of the sealing ring, the core tubes are connected with the sealing connection ring via annular rubber sheets, each core tube is provided with a main wire through hole at the axial center, the binding posts are circumferentially distributed in the periphery of the core tubes, each binding post is provided with a terminal whose vertical direction is consistent with the axial direction of the core tube, each terminal is provided with a plastic column that wraps the middle segment of the terminal, each annular rubber sheet is internally provided with a concentric annular support which is connected with the plastic columns, inlayed in the annular rubber sheet, and integrated with the annular rubber sheet, the two ends of each terminal are respectively placed at the two sides of the corresponding annular rubber sheet, each jack includes two arched sidewalls concentric with the annular rubber sheet and opposite to each other, and one arched sidewall is provided with a gap that is clamped with a plug. The problems in heat radiation and electromagnetic compatibility are solved, time and labor are saved during upgrading and reconstruction, and the integrity is high.

[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.
