DEVICE FOR FIXING connecting wires, boxes for electrical components, WHICH IS USED TO HANG UNIT WIRES AND INDOOR UNIT FOR AIR CONDITIONING UNIT

摘要

[Object] The present invention aims to suppress not only a tensile force in a pulling direction but also a tensile force in a twisting direction being applied to a connection part between a connecting wire and a terminal block regardless of the specifications of the connecting wire. [Solution] Provided is a connecting wire fixing device 70 including a wire mounting member 12 and a wire presser 13 disposed opposite to each other so as to hold a connecting wire 200 therebetween, the wire mounting member 12 and the wire presser 13 being provided, in their opposite surfaces 12a, 13a, with wire presser ridges 50, 51, 52 stretching in a cross-wiring direction 310 at alternate positions in a wiring direction 300, and holding the connecting wire 200 by means of these ridges 50, 51, 52, wherein the ridges on at least one of the wire mounting member 12 side and the wire presser 13 side are composed of two or more ridges aligned in the wiring direction, and at least one ridge of the two or more ridges has a flat wire pressing surface at the protrusion tip, while the other ridges including those on the other side have a triangular shape with the protrusion tip forming an acute angle.
