Description

Technical Field

[0001] This utility model relates to the field of wiring mechanism technology and belongs to a new type of wiring component. Background Technology

[0002] With the adjustment of the global energy structure and the increasing awareness of environmental protection, new energy vehicles, especially pure electric vehicles and hybrid vehicles, have developed rapidly. As the core of the vehicle, the electric drive system, power battery pack, and high-voltage power distribution system need to be connected by a large number of high-power cables to transmit high-voltage, high-current electrical energy.

[0003] In existing technologies, the internal wiring of new energy electric vehicles, especially the high-voltage wiring harness, generally suffers from the following technical defects that urgently need to be addressed: 1. Difficulty in cable fixing and layout: Cables are long, thick, rigid, and heavy, making fixing difficult and resulting in messy layout. 2. Cable joints are too large, taking up a lot of space. 3. Cable bends are too large, taking up too much space and making installation difficult. 4. Due to the influence of cable joints and bends, the layout space in the switch room is too large.
