Description

Technical Field

[0001] The utility model relates to a high-voltage wiring harness for an automobile. Background Art

[0002] The overall automotive wiring harness can be divided into two types: low-voltage wiring harness and high-voltage wiring harness. Traditional fuel vehicles mainly use low-voltage wiring harnesses, while new energy vehicles mainly use high-voltage wiring harnesses. High-voltage wiring harnesses can be configured in the internal and external wiring harness connections of electric vehicles according to different voltage levels. It is mainly used for internal wiring harness signal distribution in the distribution box, efficient and high-quality transmission of electrical energy, shielding of external signal interference, etc. High-voltage wiring harnesses are the neural network of the high-voltage system of new energy vehicles.

[0003] During the installation process, the automotive high-voltage wire harness usually needs to be fixed and positioned by a positioning ring. However, when fixing the automotive high-voltage wire harness, the positioning ring cannot be well attached to the surface of the automotive high-voltage wire harness according to the thickness of the automotive high-voltage wire harness. When fixing a thinner automotive high-voltage wire harness, the automotive high-voltage wire harness is easy to move in the positioning ring with the vibration of the car body, which can easily lead to poor contact at the connection end. When fixing a thicker automotive high-voltage wire harness, the positioning ring is easy to squeeze and deform the automotive high-voltage wire harness, affecting the overall service life of the automotive high-voltage wire harness. Therefore, how to better limit and fix automotive high-voltage wire harnesses of different thicknesses and avoid squeezing and deforming the automotive high-voltage wire harness is an important problem that needs to be solved in the design of automotive high-voltage wire harnesses.
