可选的，第二拉板6包括用于套接线缆的套筒601，套筒601内壁上设有第二卡钩602，第二卡钩602设于套筒601的端部，第二卡钩602与第一卡钩502连接。
可选的，第二拉板6呈筒状，第二拉板6的前端设置有第二卡钩602，第二卡钩602与第一卡钩502卡接连接，避免第二卡钩602脱落，方便拆装。
电源连接器在自锁状态下，地线端子9插入时，端子9向卡片4施加作用力，在将端子9插入到通孔底部时，端子9将卡片4压平，端子9与触片8连接之后，在弹簧7的作用下，卡片4复位并呈倾斜状态，若从电源连接器中拔出端子9，卡片4对端子9产生阻力，使端子9不能被拔出。
电源连接器在解锁状态下，将第二拉板6下拉，第二拉板6带动第一拉板5移动，第二拉板6施加在第一拉板5上的拉力与弹簧7的弹力相抵，使得卡片4向下移动并呈水平状态，此时，卡片4不再对端子9施加阻力，可顺利将端子9拔出。
本实施例提供一种电源线，包括电源线本体10和上述任一电源连接器，其中，电源线本体10的一端连接有上述具有自锁功能的电源连接器。
电源线本体10包括零线、火线和地线，三根线分别连接到相应的触片8上，第二拉板6的套筒601套接在电源线本体10上，解锁时，第二拉板6可以沿电源线轴线方向移动。
工业实用性
一种电源连接器和电源线，其中，电源连接器具有自锁功能，解决相关技术中存在的电源端子可轻易拔出电源连接器导致的安全性低的问题。
