[0010] The plug body is composed of a head, an isolating part and a tail. A terminal insertion column corresponding to the terminal connection groove is arranged on the head. The isolating part is arranged between the head and the tail, and a limit block is arranged on the side of the isolating part.

[0011] Preferably, at least one pair of positive and negative terminal connection grooves and a plurality of electronic signal terminal connection grooves are provided in the inner concave cavity.

[0012] Preferably, the positive and negative terminal connection grooves are symmetrically arranged, and other electronic signal connection grooves are staggered with the positive and negative terminal connection grooves.

[0013] Preferably, at least one pair of positive and negative terminal insertion posts are provided at the head of the plug body, and a plurality of electronic signal terminal insertion posts correspond to each other, and the position relationship is mirror-imaged with the socket body.

[0014] Preferably, the top height of the terminal connection groove is flush with the contact plane of the concave cavity.

[0015] Preferably, a plurality of insertion posts on the plug body are placed in the groove of the head, the outer shell of the groove fits with the inner concave surface of the inner concave cavity, and a limit block is provided to limit the insertion depth of the plug.

[0016] Preferably, the positive and negative terminal connection grooves are in a teardrop shape and are bilaterally symmetrical, and the other several electronic signal connection grooves are respectively arranged at both ends of the positive and negative terminal connection grooves.

[0017] It can be seen from the above technical solution that compared with the prior art, the utility model ensures the dryness of the interior through the embedded connection between the plug body and the socket body, preventing liquid from splashing into the interior. At the same time, several internal terminals are independently arranged with various insertion grooves, which have very strong moisture-proof performance. BRIEF DESCRIPTION OF THE DRAWINGS
