Information

Energy storage connector manufacturers are here to show you that the temperature rise of new energy vehicle connectors is affected by the following factors:

good price and quality Energy storage connector manufacturers
1. Contact resistance of new energy vehicle connector: ​Energy storage connector manufacturer tells you the resistance between two contact carriers for conductive connection, such as the contact resistance of the pinhole to the plug, the crimping resistance of the pinhole tail and the wire, The contact resistance of the threaded copper plate and the copper plate.
2. Environmental heating of new energy automobile connector materials: Energy storage connector manufacturers tell you that when the automobile connector is in a high temperature environment for a long time, because the materials used in the connector are engineering plastics, metal, rubber, etc., especially those required by engineering plastics The higher operating temperature is 140°C, but when the product is used in a high temperature environment, the connector heats up due to its own contact with the internal resistance. When the thermal equilibrium is reached, the ambient temperature is higher than the maximum operating temperature allowed by the material. At this time, if the car connector is in this environment for a long time, and the internal temperature cannot be released due to the heating of the pinhole inside the connector, the internal temperature will continue to rise, and the connector will generate a lot of heat, causing the connector to burn eclipse. The manufacturer of Energy storage connector tells you that this will cause the vehicle to burn, which is a very serious problem. Both rubber materials and metal materials have maximum operating temperature limits, so both need to be considered when designing.
3. New energy vehicle connector board end connection: Energy storage connector manufacturer tells you that when bolts are used in the design, precautions should be taken to prevent loosening during supply; at the same time, when connecting bolts, torsion tests must be carried out according to operating specifications. In the case of screw connection of conductive parts, one of the main failure modes is that the tightening torque is not controlled according to the torque requirement, which leads to abnormal temperature rise and ablation of the connected parts.
4. New energy vehicle connector derating curve: Energy storage connector manufacturers tell you that the derating curve is just like choosing a product. This product should be used in a specific environment. At this point, when selecting a product, determine the product range you choose according to the attribute value of the product. The derating curve diagram of the car connector is to provide customers with a menu, and customers can choose their own dishes according to their tastes.
The manufacturer of Energy storage connector tells you that the derating curve of automotive connector corresponds to different values ​​of different currents under different working environment temperatures. These values ​​are graphs obtained by the point method. Through this derating chart, you can view the usage of the connector more intuitively.
