Since new energy vehicles have high requirements for environmental protection, relevant parts also need to meet environmental protection flame retardant standards. In terms of safety, due to the high ability of new energy vehicle connectors to withstand 250A current and 600V voltage, the need for high standards of flame resistance and protection against electric shock is obvious, and at such a large power, electromagnetic interference is another important factor issues. In addition, the insertion and extraction of connectors can create arcs, which can severely damage electrical connections and electronics, and can cause car burns, all of which require special design and development of connectors.
New energy vehicle connectors mainly meet their high performance requirements through strict design specifications. For example, in the case of exposure to the sun, to prevent the high voltage from penetrating the air, it is necessary to reserve a certain air gap in the case of high voltage and high current. Its temperature rise cannot exceed the rated value; weight, strength and ease of processing should be considered when selecting the housing material, as well as how to maintain the stability of the performance of the connector terminal material at different temperatures, and how to ensure the necessary conductivity, etc. All need to be considered.
In terms of stability, due to the continuous expansion of in-vehicle entertainment systems, the importance of high-speed data transmission has become increasingly prominent. For example, on some models, cameras are mounted on the rear-view mirror to give the driver a wider field of view. Connectors are needed to transmit more data, and sometimes connectors are needed to solve the problem of transmitting GPS signals and broadcast signals at the same time, which requires improving its data transmission capacity, and the connectors also need to withstand high temperatures, because the car engine is usually placed in the car. Previously, despite the firewall, some heat was conducted, so the connector needed to be able to withstand high temperatures.
With more and more applications of new energy vehicle connectors, the integration trend of automobiles makes the integration of connectors higher and higher. Due to the space design requirements of automobiles, connectors are also required to be smaller in size and do not occupy a lot of space, and more and more signals are received by a single connector.
