PHASE-SELECTION ELECTRIC PLUG-SOCKET DEVICE

摘要

PURPOSE: To reduce the width of a plug-socket device by providing all phase sockets in a deviated manner in the longitudinal direction so that the center of each phase socket is on the line forming the prescribed angle to the longitudinal direction. CONSTITUTION: Phase sockets of sockets of a plug-socket device are provided in a deviated manner by the range of the length of the phase socket in the axial direction of the cable so that its center is on the line forming the prescribed angle in the longitudinal direction. An inclined sliding piece 24 is provided in an inclined manner to the axis of the cable in the direction of the line 25 forming the determined angleα, and a pin 11 is movable to two position indicated by the normal line. The width of the phase selection plug-socket device for a lamp capable of being moved orthogonal in the sliding guide piece can be reduced.
