摘　　要：文章介绍最近行业中电动汽车高压连接器端子专利技术研究进展情况。高压连接器端子壳体通过冲压成型代替机加工方式可降低加工成本。高压连接器端子一般采用簧片接触点的分层设计来降低插拔力。叠片连接器的孔状弹性臂是降低叠片端子插拔力比较好的方法。通过接触片双层设计、不锈钢加强、簧片焊接、线簧引入可提高高压连接器端子电性能的可靠性。The article introduces the recent research progress of patent technology for high-voltage connector terminals of electric vehicles in the industry.The shell of the terminals can be made with the punch forming in place of the machine cutting for the low manufacturing cost.The insertion and extraction force can be reduced with the common hierarchical design methodology of the spot of the contacting reed and or with the elastic oval-hole arms.The electric reliability of the terminals of the high-voltage connector can be raised by the double contact chips,or the strengthening with the stainless steel,or welding reed,or sting.
