Through-wall connector

The utility model relates to a through-wall connector which comprises a socket and a plug, a cable cover assembly is connected behind the plug, a socket insulator assembly is arranged in a seat shell, more than one guide sleeve, a jack assembly and a differential socket assembly are connected on the socket insulator assembly in a penetrating mode, and the guide sleeve is of a bidirectional opening structure. The jack assembly is a plurality of two-way opening jack structures penetrating through the socket insulator assembly, and the differential socket assembly is of a two-way opening structure in which a two-way differential jack assembly penetrates; more than one guide column, a contact pin assembly and a differential plug assembly are connected onto the plug insulator assembly in a penetrating manner; and a differential contact pin assembly which is correspondingly inserted into the differential socket assembly is connected into the differential plug assembly in a penetrating manner. The structure is simpl
