POWER SUPPLY TAP

PURPOSE:To make the fixing and the power supply wiring of a plug socket easier by gearing and fixing the plug of the plug socket dismountable to the edge of a case opening, and connecting the power supply connections of plural plug sockets through common conductive plates. CONSTITUTION:A plug socket 11 is formed of a body 13 and a cover 14, and both members are geared dismountable through a gearing projection 17 and a gearing hole 20. The plug socket 11 can be fixed easily to the peripheral edge of a case opening 2 dismountable through claw pieces 18 without using a screw and the like. Plural plug sockets are fixed to a case, and their power supply connection terminals 16 are connected to an external power supply through plate metals 22 or 23 of a conductive material. The plate metals 22 and 23 are formed of a punched plate or a printed plate and they are arranged in good order separately from each other. In the case of the plug socket with an earthing electrode, the earthing electrode is convenient to connect with cords to plug sockets arranged parallel at the outside.
