I believe everyone is well aware that high-voltage connectors are an important component in the new field of new energy vehicles. It is mainly composed of contact body, insulator, shell and accessories. The operating voltage range of new energy vehicles has been increased from 12V to 400V in traditional vehicles, which puts forward higher requirements on the quality and accuracy of connectors, and has related applications in the entire vehicle and charging facilities.

New energy automobile connector manufacturers are distributed all over the world, most of which are Japanese companies, including Sumitomo, Nissan, Yazaki, Toyota, etc. The strongest domestic companies are Busbar and China Southern Power Grid. The high-voltage connector on the whole vehicle is used to connect the following systems: power battery, high-voltage wiring harness, switch, electric air conditioner, DCDC, charger, DC charging port, AC charging port, motor, inverter, etc.


High mating cycles, heat resistance and current-carrying capacity are key considerations during development. The production of new energy automobile connectors must use materials with high temperature resistance in the selection of materials. The requirements for sealing, shielding and waterproofing are higher than traditional automobile connectors, so the cost is also higher. From the perspective of technical composition, there are more patents for electrical control and motor connectors, and fewer improvements to charging, battery connectors and ground shielding. High-voltage cables need to consider preventing overheating or burning, shielding performance, waterproof and dustproof, and electromagnetic compatibility with the electrical system of the vehicle. In actual use, the magnetic interference generated by the high-voltage cable will affect the integrity and accuracy of the data transmission in the car signal line, and in severe cases will affect the safety of the entire vehicle. Therefore, high-voltage cables need to use shielded wires to reduce magnetic interference. Cables involving battery pack voltage collection and temperature collection have high requirements for crimping processes, and hydraulic equipment needs to be used to replace traditional processes. In order to reduce fuel consumption, it is also a technological development trend to use aluminum instead of the currently widely used copper to process high-voltage cables.

After reading the above, you should know what are the factors that need to be considered in the production of new energy vehicle connectors.
