The invention relates to a direct-type socket internal structure, and the structure is technically characterized in that the structure consists of a line end sleeve and a plug sleeve; the line end sleeve comprises a wedge-shaped plug and a sleeve; one end of the sleeve is vertically fixed on one end face of the wedge-shaped plug, and the other end of the sleeve is provided with a wide guide hole which is a little wider than a wire; the central part of the sleeve is provided with an anti-fall projection and a fastening piece; the plug sleeve consists of a sleeve clamp and a groove body; the sleeve clamp can be installed on the back surface of the groove body at any angle; the wedge-shaped plug of the line end sleeve is inserted into the groove body of the plug sleeve, and the plug sleeve is fixed on a socket panel. The structure is reasonable in design, is used for an indoor socket, does not need any tool, can directly complete the connection of a wire with the socket panel without manual screwing through manual operation, brings convenience to the installation of the socket, saves labor and time, is firm and reliable, and is not limited by the activity space of the surroundings.
