How to troubleshoot electrical performance faults in new energy vehicle connectors?

First, poor contact in the structure, the new energy vehicle electrical connector internal metal conductor is the core part of the whole device. Used to connect the external wire or cable voltage or current and data signals are equal to each other, and transmitted to each other to match the connector contacts. Therefore, the connector design shall require automotive connectors have a good structure, reliable stability and good electrical conductivity, because this often happens. There are many reasons, it may be the connector contact part of the design is not reasonable, material selection problems, or processing size does not meet the design requirements, rough or installed in the wrong way, etc., will lead to poor connection between the connector and the device. Therefore, contact problems are something to consider when electronic equipment fails. All connectors should be checked, and other problems should be considered when the connection is tight. If it's not an internal connection problem, dial it in and you're good to go. It is also important to pay attention to connector protection during use. Sometimes poor contact is due to improper protection, resulting in localized damage or corrosion of the connector. Generally this situation caused by poor contact is difficult to repair, need to replace the connector, not only trouble, but also a waste of resources, resulting in economic losses. Second, poor insulation which mainly refers to the impact of the external environment. Generally the performance will be unstable, and the leakage phenomenon will be more terrible. It can be observed intuitively. But when encountering such a problem, the connector of the new energy vehicle should be shut down and directly replaced. The main electrical properties of new energy vehicle electrical connectors include contact resistance, insulation resistance and electrical strength.1. Contact resistance: a good electrical connector should have a low and stable contact resistance, the connector's contact resistance ranges from a few milliohms to tens of milliohms.2. Insulation resistance: a measure of the electrical connector between the contacts and the contacts and the shell of the insulation between the indicators, the order of magnitude from a few hundred megohms to tens of megohms. 3. Electrical strength (withstand voltage): indicates that the connector contacts withstand the rated test voltage or between the contacts and the shell capacity.
