When the TYPE-C plug 1 and the TYPE-C socket 2 are inserted into each other, the end of the metal elastic locking arm 11 is inserted into the locking groove 301 of the secondary shielding shell 3, and the protruding buckle 111 is pressed into the locking hole 302 to lock it. That is to say, the utility model is provided with a secondary shielding shell 3 wrapped on the TYPE-C socket 2, and the secondary shielding shell 3 is also welded and fixed to the PCB4, so that the TYPE-C socket 2 can be limited to the PCB4, ensuring that the TYPE-C socket 2 is more stably installed on the PCB4, and the secondary shielding shell 3 can further increase the shielding effect, which can make the anti-interference ability of the TYPE-C socket 2 stronger, and improve the quality of signal transmission. In addition, the secondary shielding shell 3 is also inserted into the metal elastic locking arm 11 of the second metal shell 13 in the TYPE-C plug 1 through the locking groove 301, and the convex buckle 111 is pressed into the locking hole 302 to lock, so that the TYPE-C plug 1 and the TYPE-C socket 2 are stably connected together and form a reliable electrical connection.
