PURPOSE:To facilitate the replacement of a printed circuit board and to ensure the contact or a plug to a core wire by forming a guide hole so that a core wire fixing metallic fixture is supported to a position not interfering with the core wire and to a position in press contact with the core wire with tightening of a screw. CONSTITUTION:A side wall 28a of a guide bracket 28 is formed to be cylindrical around a screw 27 and a guide hole 29 is formed thereto in spiral in a range of nearly 90 deg.. One end 26a of a core wire fixing metallic fixture 26 is inserted to the guide hole 29, the core wire fixing metallic fixture 26 is guided around the screw 27 and connected /disconnected to/from a connection terminal 25. The metallic fixture 26 reaches a position not interfering with the core wire 24 in almost parallel direction when the screw 27 is not tightened, the one end 26a of the metallic fixture 26 enters in a channel shaped folded piece 25a at one end of the connection terminal 25 and reaches a position at which the core wire 24 is inserted between the other end 26b of the metallic fixture 26 and the other end 25c of the connection terminal 25 when the screw 27 is tightened. |
