Claims (7)

A wiring device comprising: a locking spring integrally comprising: a central piece, a contact piece and a locking piece extending from both ends of the central piece; the quick-connecting terminal plate integrally comprises: a connecting part, and the connecting part a contact piece and a pressing piece extending from both ends; and a frame body comprising: a terminal receiving chamber for accommodating the locking spring and the quick-connecting terminal plate; and a wire insertion opening through which the conductor of the electric wire can be inserted In the terminal housing chamber, the quick-connecting terminal plate and the locking spring are housed in the terminal housing chamber, and the abutting piece and the pressing portion are in a state where the connecting portion on the pressing piece side faces the electric wire insertion opening. The sheet extends from one end of the connecting portion toward one side of the wire insertion opening, and in a state where the center piece contacts the abutting piece, the contact piece is located on one side of the connecting portion, and the locking piece is located at the abutting portion Between the front end and the front end of the pressing piece, the frame body includes: a storage wall, which is parallel to a surface opposite to the pressing piece when viewed from the locking spring; the storage wall and the storage wall Pressing the film The front end has a convex portion, and the pressing piece has a protruding portion between the receiving wall and the pressing piece in a position away from the convex portion. The wiring device of claim 1, wherein the central piece has a rectangular plate shape extending in one direction, and the contact piece has an S-shaped cross section, and the first end of the central piece faces one side of the central piece. Sidely extending, the locking piece is composed of a curved portion extending from a second end of the central piece toward a side of the one side of the central piece, and a rectangular flat portion extending from the curved portion, The connecting portion has a flat shape, and the abutting piece and the pressing piece protrude parallel to each other from both ends of the connecting portion. The wiring device of claim 1, wherein the convex portion is disposed between two positions corresponding to a front end of the pressing piece and a front end of the locking piece. The wiring device of claim 2, wherein the convex portion is disposed between two positions corresponding to a front end of the pressing piece and a front end of the locking piece. The wiring device according to any one of claims 1 to 4, wherein the protrusion is provided at a position corresponding to an intermediate portion of the center piece. A wiring device according to any one of claims 1 to 4, wherein the wiring device is a switch module. For example, in the wiring device of claim 5, the wiring device is a switch module.
