The implementation of the invention
Outlet 1 electrical connector still installed in the casing of electrical apparatus (in the General case: the body of the machine). It is located in the cylindrical cavity pin contact part 31, which is oriented parallel to the axis of the receptacle, pass through the bottom outlet and protrude into the cavity of the receptacle. To the ends of the pin contact detail is her protruding from the bottom of the outlet opposite the bottom side, soldered the ends of the conductors 25, 26.
Movable plug head 2 in its contour corresponds to the cavity of the receptacle. She has a female contact part 32, which is oriented parallel to the axis of its cylindrical shape, are arranged in the same geometric pattern, and pin the contact details in the receptacle and with the introduction of the plug head into a wall socket are in connection with them. Since pin contact details and socket contact details are distributed asymmetrically in the cavity of the socket parallel to the pin contact detail is the guide pin 6 and the plug head has a guide hole 7 is made in the corresponding geometric position. Socket contact details of their free ends, with back entrance holes hand, are connected by soldering to the ends of electrical conductors 25, 26. Electrical conductors 25, 26 are omitted in the body of the plug by the inverse of the plug head. Plug the head part of its length, which in the articulated condition is thrown over the edge of the receptacle, mounted in congruent her body cavity of the plug.
