Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and more specifically, particularly relates to a high-voltage wire harness connection structure for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and new vehicle power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] From the perspective of the development of new energy vehicles around the world, their power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, lead-acid batteries, and supercapacitors, among which supercapacitors mostly appear in the form of auxiliary power sources. The main reason is that these battery technologies are not yet fully mature or have obvious shortcomings. Compared with traditional vehicles, there are many gaps in terms of cost, power, and mileage, which is also an important reason restricting the development of new energy vehicles.

[0004] Automotive wiring harnesses can be divided into two types: low-voltage wiring harnesses and high-voltage wiring harnesses. 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 electric vehicles and external wiring harness connections according to different voltage levels. It is mainly used for internal wiring harness signal distribution in the distribution box, efficiently and effectively transmits electrical energy, and shields external signal interference. High-voltage wiring harnesses are the neural network of the high-voltage system of new energy vehicles, which is crucial to the operation of new energy vehicles.

[0005] The high-voltage wiring harness of new energy vehicles is mainly composed of connectors, terminals, wires and coverings. It can be configured in the internal and external wiring harness connections of electric vehicles according to different voltage levels. It is mainly used for the internal wiring harness signal distribution of the distribution box, efficient transmission of electric energy, and shielding of external signal interference. Due to the characteristics of high voltage / high current, large wire diameter and large number of wires in the car, the design of the wiring harness faces challenges such as wiring, safety, shielding, weight and cost.

[0006] However, there are some problems with the existing technology: when the terminals in the existing high-voltage wire harness are connected, because the electrode columns use copper columns with constant diameter, they are prone to detachment and poor contact when the terminals are connected. Therefore, we propose a high-voltage wire harness connection structure for new energy vehicles. Summary of the invention
