Technical Problem
然而，密封圈的内径通常是固定的，需要根据导线的具体尺寸进行选择和替换，从而更换相应规格的密封圈，操作颇为繁琐，使用较为不便，此外，插头的导线受到拉拽力的影响，导线带动密封圈移动，甚至导致密封圈从插头内脱落，从而丧失防水功能，给用电安全带来隐患
Benefits of technology
[0014]插头结构安装在壳体的穿线侧，插头结构的导线穿过安装管，安装管内插接有密封套，密封套套接在导线上，内径不同的第一内圈壁和第二内圈壁使得密封套可适配不同径长的导线，通过密封套与导线紧密接触，确保插头的防水性能；卡位环的外径大于安装管的内径，使得两个卡位环分别与安装管的开口侧和形变环的开口侧抵触配合，防止密封套随导线移动而脱离安装管，并且，利用穿线套与安装管可拆卸连接，使得抵靠部与形变环相互抵紧，形变环受压变形以驱使密封套变形，加强第二内圈壁与导线之间的抵紧配合，不仅实现了对导线的有效防水密封，还提高了插头的维护便利性和安全性。
