<p>PURPOSE:To contrive to facilitate the construction of apparatus by forming a plate frame body, where a fitting frame and a plate frame are formed into an integral body and by constituting said plate frame body in such manner that said body can be removably fitted with wiring accessories. CONSTITUTION:Respective members of a quadrangular frame-shaped plate frame body 21 are formed into an integral body by an insulating material and the central part of said plate frame body is provided with an opening 2, where three wiring accessories can be arranged. Above and below said opening 2, there are made slots 5 for fitting to an embedded box. A pair of detent holes 12 are formed in one side piece 22 of the plate frame body 21, while a detent side piece 24 is formed in the other side piece 23 to form detent holes 16. The back face of said detent side piece 24 is formed almost in the same surface as the back face of the plate frame body 21 excepting the part of a guide 41. Further, a tapered face 43 for guiding a detent piece for said wiring accessories, when said detent piece is inserted from the back face, is formed in the inner side face below the lateral ribs 42c of the guide part 41, and ribs 42 are integrally formed on both sides of said guide part 41.</p> |
