Abstract: A waterproof connector includes a plug body with conductive blades connected internally to wires extending from an opposite portion of the plug body and a socket body having a channel in its front face. An electrical contact supporting member is arranged to fill the channel in the insulative socket body in such a manner as to define slits between opposite walls of the channel and opposite outside walls of the member. By providing electrical contacts on the opposite outside walls of the member, the plug blades can be urged into the slits to expand the slits and thereby result in a wiping action against the blades in effecting a connection.
