Problems solved by technology

[0006] However, in the conventional wiring device, as shown in FIG. 35(a), since the inner peripheral surface H1 of the tool insertion hole 116 and the inner wall surface H2 in the joint receiving chamber 109 of the main body 101 become the same plane, therefore, as shown in FIG. 35 As shown in (b), the amount of action (movement) of the release button 117 operated by the screwdriver 120 inserted from the tool insertion hole 116 is only the width dimension of the front end of the screwdriver 120, especially with a screwdriver with a small width dimension at the front end. The amount of action of the button 117 is small, so the release performance of the wire caused by the release of the button 117 is reduced.

Embodiment 1

[0066] The socket of this embodiment is as Figure 2 to Figure 5 As shown, a substantially box-shaped synthetic resin body 10 with an open front surface and a substantially box-shaped synthetic resin cover 20 with an open rear surface that is covered on the front surface of the body 10 are fitted by fitting on both sides. The parts 60, 70 are combined with the fitting holes 51, 51 of the combination frame 50 by concavo-convex fitting to form the main body of the appliance.

[0067] The interior of the main body 10 is divided into three regions at the center and both ends by a pair of partition walls 11, 11 along the longitudinal direction, and then extended from the side surfaces of the partition walls 11, 11 to the interior of the main body 10 opposite to the partition walls 11, 11. A pair of partition walls 12, 12 near the wall surface divides the regions at both ends into three storage chambers respectively, that is, the blade holder storage chambers 13a, 13a that accommoda...

Embodiment 2

[0092] The socket of embodiment 1 has only one utensil main body of installable size on the plate frame 130 described later, but the socket of this embodiment is shown in Figure 22, has the utensil main body of the socket of embodiment 1 along its length direction. When divided into three equal parts, one equal part has approximately the same size (hereinafter, this size will be referred to as “one standard size”). Up to three device bodies can be mounted side by side on the same plate frame 130 . In addition, since the size of the instrument main body of Example 1 is 3 times of 1 standard size, it is called 3 standard sizes.

[0093] The socket of this embodiment is a single-port socket without grounding poles having only two insertion openings 25 as the embedded part 24. Although there are some differences in size and details, the basic structure is substantially the same as that of Embodiment 1. Therefore, the same symbols are assigned to the same components, and detailed d...

Embodiment 3

[0107] The socket of this embodiment, as shown in Figure 33, is a single-port socket with a grounding pole having only one embedded part 24. A pair of insertion openings 25, 25 of the plug insertion opening 25b and an insertion opening 26 for a ground electrode are constituted. In addition, although there are some differences in dimensions or details, the basic structure is substantially the same as that of Embodiment 1 or Embodiment 2, so that the same components are given the same reference numerals, and their illustrations and detailed descriptions are omitted.

[0108] In addition, as the cover 20, as shown in FIG. 34, a structure may be adopted in which the insertion portion 24 has an insertion opening 25 consisting only of a flat plug insertion opening 25a and an insertion opening 26 for a ground electrode. If the main body 10 is used in common By replacing only the cover 20 with the knife holder, a single-port socket with a ground electrode can be formed, and the socket...

Abstract

The invention provides a wiring device which can enhance the electric-wire releasing property by the use of an releasing button. Fitting the projecting streak 18a in a recession formed in the internal wall surface of a body 10 into a recessed groove 37e, the releasing button 37 is arranged between two lock springs 36, 36. Since the projected part 37d of the releasing button 37 is moved into the recession 18 formed in the internal wall surface of the body 10, a quantity of action (a quantity of movement) produced when the releasing button 37 is operated by the tip of a driver 120 inserted from a jig inserting hole 16 increases by the quantity of projection of the projected part 37d having moved into the recession 18. Accordingly, it is possible to make the quantity of action of the releasing button 37 sufficient for pulling the tip of a chain lock piece 36b off from an electric wire, even if a driver whose tip has a small breadth is used for example, and enhance the electric-wire releasing property by the releasing button 37 compared to an example of the conventional accessories.

Description

technical field [0001] The invention relates to a wiring appliance. Background technique [0002] In the past, in wiring appliances such as switches and sockets, for the purpose of facilitating the wiring of electric wires or making the connection uniform to ensure connection reliability, the quick-connect head that can be connected is stored in the appliance body without screws. [0003] Fig. 35 is a partially omitted side sectional view of a conventional wiring device (tumbler switch). The main body of the wiring fixture is constituted by a substantially box-shaped synthetic resin main body 101 with an open front and a synthetic resin cover 102 covered on the front surface of the main body 101 . The interior of the main body 101 is divided into a plurality of areas by the partition wall, and joint storage chambers 109 for storing quick-connect heads are provided on both sides. Terminal boards 111 formed of conductive materials are respectively accommodated in the termina...
