The invention discloses a new energy automobile charging wire connector in the field of wire connectors, and the connector comprises a plug and a socket, the socket comprises a connecting seat and a first shell, a heat dissipation cavity is formed in the side wall of the first shell, the heat dissipation cavity is arranged around the side wall of the first shell, a ventilation pipe is fixedly connected in the heat dissipation cavity, and the section of the ventilation pipe is in an hourglass shape. Annular bimetallic strips are fixedly connected to the two sides of the ventilation pipe, a compressed air cavity is formed between the annular bimetallic strips on the two sides of the ventilation pipe, the ventilation pipe communicates the connecting cavity with the exterior of the first shell, and a first compressed air hole is formed in the end, close to the outer side wall of the first shell, of the ventilation pipe and communicates the interior of the ventilation pipe with the compressed air cavity; the rest area of the heat dissipation cavity is divided into exhaust cavities by the annular bimetallic strip, and the exhaust cavities are all communicated with the outside of the heat dissipation cavity. According to the invention, a good heat dissipation effect at the joint of the connector lug can be maintained, and a line fault or short circuit caused by too high temperature at the joint is avoided.
本发明公开了电线连接头领域的一种新能源汽车充电线连接头,包括插头和插座,插座包括连接座和第一外壳,第一外壳侧壁内开设有散热腔,散热腔环绕第一外壳侧壁设置,散热腔内固定连接有通气管,通气管剖面呈沙漏形,通气管两侧均固定连接有环形双金属片,且通气管两侧的环形双金属片之间形成压缩空气腔,通气管将连接腔与第一壳体外部连通,通气管靠近第一外壳外侧壁一端设置有第一压缩气孔,第一压缩气孔将通气管内部与压缩空气腔连通,散热腔其余区域被环形双金属片分隔为排气腔,排气腔均与散热腔外部连通。本发明,能够保持接线头的连接处良好的散热效果,避免连接处温度过高导致线路故障或短路。
