所述的插座231的外壁上呈有环形的第二凹槽2311，第二凹槽2311的底面上成型有若干贯穿插座231的插槽2312，第二凹槽2311的侧壁上插接有环形的锁紧套25，锁紧套25的内壁上成型有若干L型的锁舌251；
第一绝缘座13上的插头131插接在第二绝缘座23的插座231内，插头131上的弹性片15插接在插座231的插槽2312内并露出第二凹槽2311的底面，锁紧套25上的锁舌251插接在第二凹槽2311底面外侧的弹性片15内。
所述的弹性片15或插槽2312环形均匀分布在第一绝缘座13的插头131或第二绝缘座23的插座231上，弹性片15和插槽2312的个数相同。
所述的第一电缆线12的端部成型有裸露的第一线头121，第一线头121上插套固定有铜插管14，铜插管14和第一线头121插接固定在第一绝缘座13内，第二电缆线22的端部成型有裸露的第二线头221，第二线头221上插套固定有铜柱24，铜柱24插接在铜插管14内。
所述插座231底部的内壁上嵌有密封圈26，插头131的头部插接在密封圈26内。
所述的锁紧套25的外壁上成型有若干个防滑条252，防滑条252环形均匀分布在锁紧套25上，锁紧套25上的锁舌251的下端呈圆弧形，锁舌251下端的圆弧弧度小于插座231上相邻插槽2312之间弧度。
工作原理：本新型结构的光伏连接器由第一连接体1和第二连接体2组成，使用时，将第一连接体1的插头131插接在第二连接体2的插座231内，同时其插头131上的弹性片15先受压变形抵靠在插座231的内壁上进入插头131内，然后弹性片15进入插座231的插槽2312内再恢复原先的形状，从而完成第一连接体1和第二连接体2的连接；从而连接较为方便，同时其铜柱24又插接在铜插管14内，连接较为紧密，同时插头131的头部插接在插座231的密封圈26内，具备加好的密封效果；而第一连接体1和第二连接体2分开时直接拔出即可；
而为了加强第一连接体1和第二连接体2的连接强度，可以旋转锁紧套25，锁紧套25上的锁舌251插接在弹性片15内，从而防止第一连接体1和第二连接体2之间相互拔出，从而使连接器具备较高的连接牢固性。
