Electric current concatenates prefabricated cable

The utility model discloses an electric current concatenates prefabricated cable, including CT incoming end (5), two secondary device, participate in with a secondary device (4) electrical connection's circular connector 1, circular connector (1) have a wiring of two branches, the wiring of first branch is through the wiring end of cable electrical connection to aviation socket, the second dividesthe wiring through cable electrical connection to the 2nd secondary device (6), aviation socket (2) and CT incoming end (5) electrical connection, will two secondary device establish ties and use same CT winding current. Through using preventing that open type circular connector and electric current concatenates prefabricated cable cooperate in a flexible way, realization current loop series wiring is applicable to two and installs the same CT winding current of series connection use, and a plug corresponds a device, does not influence other device during the plug, and it is convenient that the scene is installed, is
