Is the performance of the battery connector significantly reduced because of the high temperature rise during use, and will the function of the battery connector fail? This is a problem that people are very concerned about. Therefore, its manufacturers are the battery connector temperature rise analysis is the most basic problem that the connector industry is concerned about in the reliability design, through CAE simulation pointed out that the temperature rise change of the battery in use, etc., provides a theoretical basis for further improving the structural design, and plays a significant role in improving the reliability of the connector industry, reducing the damage rate of the product and reducing the cost.
