请参考图1至图6，所述侧壁62设有与收容空间60连通的开口620，所述第二端32能够随着插脚3的旋转而嵌设或伸出于所述开口620。侧壁62上的开口620用于收纳插脚3的第二端32，即在不使用状态下将插脚3隐藏。
请参考图3及图4，所述壳体6的上方安装有封闭该收容空间60的上盖8，所述壳体6的底壁61的下方贴附安装有下盖9。所述上盖8和下盖9起到遮蔽、保护和防尘的作用。
本实用新型电源插头的接触端子2插入成型于绝缘本体1内，即接触端子2和绝缘本体1一体成型为一个端子模组，端子模组能够整体组装入壳体6内，在使用时更稳固，损坏后方便组装更换，从而具有低成本、高强度、高安全性、组装简单等优点。
以上实施例仅用于说明本实用新型而并非限制本实用新型所描述的技术方案.，对本说明书的理解应该以所属技术领域的技术人员为基础，例如对“前”、“后”、“左”、“右”、“上”、“下”等方向性的描述，尽管本说明书参照上述的实施例对本实用新型已进行了详细的说明，但是，本领域的普通技术人员应当理解，所属技术领域的技术人员仍然可以对本实用新型进行修改或者等同替换，而一切不脱离本实用新型的精神和范围的技术方案及其改进，均应涵盖在本实用新型的权利要求范围内。
