与现有技术相比， 本发明开创性地在插座体设置了相互对应的授电和供电两 套触片组， 并且在插头体未插入插座体时， 供电触片组中至少与电源火线或零线 相连的一个与其对应的授电触片保持为常开状态， 使得在插座体表面上可见的授 电触片始终不带电， 不仅保证了安全使用， 也使插座体表面的凹槽宽度、 深度不 受限制， 使得插头体在与插座体相插接时更为方便， 即使斜向相插也能准确地插 接一体， 同时， 也使得设计、 制造、 使用大功率电连接器成为可能， 极大拓宽其 应用领域， 支持电热壶、 煎烤锅等产品多样化发展。 附图概述

如图 16、 图 17所示， 为本发明实施例七， 是实施例六的一个变化， 但其具有 一个与上述六个实施例都不同的特征， 即插座体在其上端面所开的均为同心环形 槽 （在本实施例中为三个同心环形槽 251、 252 ' 、 253 ) ， 而非中心孔和同心环 槽， 其优越之处在于， 可以克服因原中心插孔不能过大而导致的功率限制；
事实上， 对于上述实施例一至六， 也可以采用如实施例七中的变化， 即将插 座体上的中心插孔替换以一中心环形槽， 这一点很容易根据实施例一至六的附图 结合实施例七的附图得以理解， 因此具体的结构图在此省略， 其文字描述也不再
