摘　　要：针对连接器使用过程中因温升过高导致的电连接器失效问题,提出来基于温升控制的电流连接器改进设计。首先根据热传学理论建立了电连接器的传热模型,根据传热模型分析了电连接器温升的影响因素,并提出了增大接触件横截面、更换高电导率材料及加大接触件排列间距的改进措施,采用ANSYS对改进前后的电流连接器进行了有限元仿真,理论验证了改进措施的可行性。对改进前后的电连接器进行了温升验证实验,试验结果表明:改进设计后温升降低26%,有限元模型仿真温升误差在(15.2~29.3)%范围内。基于温升控制的电流连接器改进设计为电连接器的设计提供了参考。To solve the problem of electrical connector failure caused by high temperature rise during the use of the connector, an improved design of the current connector based on temperature rise control is proposed in this paper, the heat transfer model of the electrical connector was established according to the theory of heat transfer, the influence factors of the temperature rise of the electrical connector was analyzed based on the heat transfer model, Increasing the cross section of the contacts and the contact arrangement pitch , using the high conductivity material were used to reduce electrical connector temperature rise, the feasibility of the improvement measures was theoretically verified by ANSYS temperature field simulation,The temperature rise test of the electrical connector before and after the improvement was carried out. The experimental results show that the temperature rise is reduced by 26% after the improvement of the design, and the error of temperature rise in the finite element model is within the range of （15.2-29.3）%. The improvement of the current connector based on temperature rise control provides a reference for the design of the electrical connector.
