Product Description
New energy vehicle wiring harnesses can be divided into low-voltage wiring harnesses and high-voltage wiring harnesses. Different from traditional fuel vehicles, new energy vehicles use more high-voltage wiring harnesses. The high-voltage wiring harness is configured in the internal and external wiring harness connections of electric vehicles according to different voltage levels. It is mainly used for signal distribution of the wiring harness inside the power distribution box. It can transmit power efficiently and high-quality, and shield external signal interference. It is the neural network of the high-voltage system of new energy vehicles. .
New energy vehicle high-voltage wiring harness is mainly composed of connectors, terminals, cables, coverings and other parts.
1. There are three main standards for high-voltage connectors: LV series standards formulated by the four major European OEMs; SAE-USCAR 2 standards implemented in North America; China GB standards. The high-voltage connector is mainly composed of four parts: contact piece, insulator, shell and accessories. Among them, the contact piece is the core component of the connector to complete the optical and electrical signal connection; the insulator and the shell mainly play the role of fixing, insulation and mechanical protection; the accessories are divided into Structural accessories and installation accessories, structural accessories such as clamps, cable clamps, sealing rings, gaskets, etc., installation accessories such as screws, nuts, spring rings, etc.
2. The metal conductor inside the crimp terminal is the core part of the terminal, which transmits the voltage, current or signal from the external wire and cable to the corresponding contact of the corresponding connector, so the terminal must be well fixed to ensure control. System power transmission and signal control operate normally.
3. High-voltage cables for new energy vehicles are an important part of high-voltage wiring harnesses. Due to the complex interior environment, high temperature near generators and power batteries, and many corrosive liquids and gases, the cables need to be resistant to high temperature, acid and alkali, and Corrosion and other properties. OMG is a manufacturer of high-voltage cables for electric vehicles. It has many years of EV high-voltage cable supply capabilities. Its products and services are sold at home and abroad, and can meet the diverse needs of customers.
4. The covering is mainly divided into corrugated tube and heat shrinkable tube. The temperature resistance level is -40℃-125℃. It needs to meet good elasticity and flexibility, and play the role of insulation protection.
