Description

Wiring equipment

The present invention generally relates to a wiring device, and more particularly to a wiring device including a plurality of fast-connection terminals (fast-connection terminal structure).

For example, Japanese Patent Application Publication No. 2004-296231 (hereinafter referred to as “Document 1”) discloses a piano handle type switch. The piano handle type switch includes a first terminal board and a second terminal board. The first terminal plate is accommodated in a predetermined terminal accommodating chamber together with two lock springs and a release button. Similarly, the second terminal plate is also stored in a predetermined terminal storage chamber together with two locking springs and a release button.

Such a terminal is called a quick connection terminal, and the conductor can be electrically and mechanically connected to the quick connection terminal simply by inserting the conductor of the electric wire into the terminal storage chamber from a predetermined wire insertion opening.

During construction of indoor wiring, a relatively large pulling force may be applied to the wires. In this case, the electric wire inserted into the terminal storage chamber may be pulled out from the terminal storage chamber.

The present invention has been made in view of the above problems, and an object of the present invention is to prevent the electric wire from being pulled out even if the electric wire connected to the terminal receives a relatively large pulling force.

The wiring device of the present invention includes a lock spring, a quick connection terminal plate, and a container. The locking spring integrally includes a center piece, a contact piece and a locking piece extending from both ends of the center piece. The quick connection terminal plate integrally includes a connecting portion and a contact piece and a pressing piece extending from both ends of the connecting portion. The container includes a terminal storage chamber that stores the locking spring and the quick-connection terminal plate, and a wire insertion opening that is configured such that a conductor of an electric wire is inserted into the terminal storage chamber via itself. The quick-connection terminal plate and the locking spring are configured so that the contact piece and the holding piece are connected to the wire insertion port from both ends of the connection portion in a state where the portion of the connection portion on the holding piece side faces the wire insertion port. The contact piece is positioned on the side of the connecting portion with the central piece in contact with the contact piece, and the locking piece is on both ends of the contact piece and the holding piece. The terminal is accommodated in the terminal storage chamber so as to be positioned between them. The container includes a storage wall that is parallel to the opposite surface of the pressing piece through a gap when viewed from the locking spring. The storage wall includes a convex portion between the storage wall and the tip of the pressing piece. The pressing piece includes a protrusion between the storage wall and the pressing piece at a position away from the convex portion.

The present invention has an effect that it is possible to prevent the wire from being pulled out even when the wire connected to the terminal receives a relatively large pulling force.

The circuit board 20 further includes a light source (second light source) 206. The light source 206 is included in a circuit (second circuit) connected between the two terminals 203. The second circuit includes, for example, a light source 206 and a resistor 207. The light source 206 is, for example, an LED, specifically a red LED.

The transformer 21 and the transformer case 22 are stored in a central storage chamber 39 in the container 2 (body 3). For this reason, the intermediate part of the base 30 of the body 3 in the present embodiment is set back on the second side in the first direction D1 so as to secure a storage chamber for the transformer 21 and the transformer case 22. In the example of FIG. 14, the intermediate portion of the base portion 30 is set back on the second side in the first direction D 1 so as to secure a storage chamber for the transformer 21, the transformer case 22, and the intermediate member 23. The intermediate member 23 is formed in a shape corresponding to the bottom in the central storage chamber 39 in the embodiment of FIG.

Although the foregoing best mode and / or other examples are considered, various modifications may be made and the subject matter disclosed herein may be implemented in various forms and examples. And they may be applied to a number of applications, some of which are best described herein. The following claims claim any and all modifications and variations that fall within the true scope of the present teachings.
