What factors affect the performance of new energy vehicle connectors?

There are many factors that affect the performance of new energy electrical connectors. In general, the following points should be noted:1. Connectors in a humid environment will accelerate the corrosion of the connector's internal metal parts, resulting in the wetting of the surface of the pin core and the corrosion of the plastic film. So in general, the connector installation environment should not be used in too humid environment.2. Connector in the temperature is too high in the working environment will accelerate the corrosion of the pin core, the formation of surface oxidation, resulting in loss of contact pressure. And the working temperature can not dissipate the heat, may directly burn the new energy electrical connector.3. Connector used in harsh environments, the connector's air holes will be corroded, while the edges of the internal pins will be deformed, and the surface of some metal particles will be corroded. Therefore, please do not use the connector in high temperature and corrosive environments.4. With the long-term use of the connector, the wear life between the pins will be reduced. In the daily use of new energy electrical connectors, please be careful not to plug the connector randomly without using the connector, so as not to wear the internal pin core and reduce the service life of the connector.5. The insertion force of the connector is an important mechanical property. Insertion force is divided into insertion force and withdrawal force, which have different requirements. From the point of view of use, the strength of the insertion force should be slightly increased, but the strength of the insertion force should be smaller. If the separation force is too large, it will affect the contact reliability between the cores of the needle row. Many environmental factors affect the performance of new energy electrical connectors, such as temperature, humidity, acid and alkali. Let's start with the temperature as an important influencing factor. Generally due to different seasons and geographical differences, the ambient temperature will vary a lot. Connectors connect two components, the current through the heat will also be generated, resulting in increased temperature. The sum of the two is the operating temperature. The metal components in a good connector should be able to keep their physical state unchanged at some temperatures, thus ensuring their performance. The effect of humidity on new energy electrical connectors is actually the effect of water, because water is corrosive to metal components, has some conductivity, and will reduce insulation. So the connector's component materials need to be water, the impact is not significant. According to the introduction, the connector should be able to work normally for at least 96 hours in an environment where the relative humidity is 90%-95% and the temperature is about 40 degrees, i.e., the salt in the salt spray will cause damage to the metal components. In addition, vibration and shock mainly affect the firmness and reliability of the electrical contact of the connector. Usually according to the application environment of the connector, according to the relevant parameters to simulate the vibration and shock environment to test the performance of the connector.
