Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness components, and more specifically to a wiring harness component with a fixed structure. Background Art

[0002] The wiring harness assembly of new energy vehicles is like its "neural network", responsible for connecting various electrical components to ensure that they can work normally. The wiring harness is generally composed of wires, terminals, connectors, sheaths, etc. It can connect key components such as batteries, motors, and electronic controls together to transmit power and signals. Moreover, in order to adapt to the special needs of new energy vehicles, the wiring harness assembly also needs to have high temperature resistance, anti-interference, waterproof and other characteristics.

[0003] The existing wire harness assembly with a fixed structure is usually fixed to the line structure with a strapping tape. This fixing method is not firm, and it is difficult to find a structure to support the strapping tape at many line turns, resulting in poor fixing effect and poor adaptability. In addition, since the existing wire harness assembly structure is relatively simple and general, the sealing of the wire core is strong, which makes it difficult for the heat generated by the wire core to dissipate, making the heat resistance and heat dissipation effect of the wire harness assembly poor. In view of this, we propose a wire harness assembly with a fixed structure. Utility Model Content
