Description

[Detailed description of the invention] 〔Technical field〕 TECHNICAL FIELD This invention relates to wiring devices.

[Background technology]

Figure 10 shows a telephone outlet. This outlet includes a housing 2 and a front cover 3 as an outlet body 1, which are connected to each other. The housing 2 includes an insert setting port 4 in a small diameter portion, and an attachment/detachment port 5 in a large diameter portion. The next modular insert 6 is set in the insert setting port 4. The modular insert 6 consists of an insert body 7 and a connecting piece 8, and the insert body 7 has a thin first insertion hole 9 and a slightly thicker second insertion hole 10 formed in the center thereof.

The connecting piece 8 was initially in the shape of a straight pin, and the first connecting piece 8 was attached to the insert body 7 before assembly. It is inserted through the second insertion holes 9 and 10 and set so that both ends protrude outside the insert body 7.

A lead wire 12 is connected to one protruding end of the connecting piece 8 by a caulking metal fitting 11, and then the connecting piece 8 is set so that the connecting portion thereof is inserted into the second insertion hole 10. The other end of the connecting piece 8 is bent to form a contact piece 13. The modular insert 6 unitized in this way is fitted into the insert set opening 4 through the attachment/detachment opening 5 and is inserted into the engaging protrusion 14 on the outer periphery of the insert body 7.
is engaged with the engagement hole 15 of the housing 2, and the contact piece 1
3 is set so as to fit into the setting groove 16 of the housing 2. By inserting the contact piece 13 into the plug socket 17 of the housing 2, a modular plug 18 provided at one end of the telephone modular cord 17 is inserted into the plug socket 19 and comes into contact with the contact piece 13. ing. On the other hand, the lead wire 12 is connected to each connection piece 8.
The other end of these lead wires 12 is provided with a washer 20 and a spring washer 21, and a terminal of an electric wire (not shown) can be attached to it with a wire tightening screw 22. Solder each to the terminal board 23 2
4. This terminal board 2
3 is inserted together with the mosier insert 6 and set in the attachment/detachment opening 5, and a rear cover 25 is attached to the housing 2.

As described above, in the conventional electrical outlet, the lead wire 12 is connected to the connection piece 8 via the caulking metal fitting 11, and the lead wire 12 is soldered to the terminal plate 23. Since such a connection method was adopted, the number of assembly steps was increased, making the assembly troublesome and causing an increase in costs. Moreover, since the lead wire 12 is used, there is a risk of incorrect wiring.

[Purpose of the invention]

In view of the above-mentioned disadvantages, it is an object of the present invention to provide a wiring device that is easy to assemble, can reduce costs, and is free from the risk of erroneous wiring.

[Disclosure of the invention]

In order to achieve the above object, the wiring device according to the present invention is provided with a connection piece inserted through an insert body having an insertion hole with one end opened, and a connection piece provided at one end of the connection piece. The contact piece is located in the insertion hole, and the contact piece provided at the other end of the connection piece bends and protrudes from the insert body, forming a modular insert. A terminal board is set in the outlet body through the outlet so that the contact piece is inserted into a plug insertion hole formed in the outlet body, and the terminal board is separate from the connection piece. In the wiring device that is set in the outlet body through the attachment/detachment port and connected to the connection part, the connection part of the connection piece and the terminal board are connected in a plug-in type by the elasticity of one of them. It is characterized by

The present invention will be described below with reference to the drawings showing embodiments thereof.

FIG. 1 shows an example of a wiring device according to the present invention, and in this embodiment, a telephone outlet is taken as an example. The outlet body 1 includes a housing 2, and the same reference numerals as in FIG. 10 are given to the parts including the housing 2 which have the same structure as those described in the background art section, and the description thereof will be replaced by the same reference numerals as in FIG. The connecting piece 8 inserted through and attached to the modular insert 6 is as follows. In other words, at one end of the connection piece 8, the second
As shown in the figure, a blade receiving spring-shaped connecting portion 26 is integrally formed. The connecting portion 26 is formed by a pair of opposing holding portion pieces 26a, 26a extending from two sides of the U-shaped joint portion 27. On the other hand, as shown in FIG. 3, the terminal board 23 is integrally equipped with a long and thin insertion pin 28 at the tip of its L-shaped bent portion, and this insertion pin 28 is connected to the connecting portion 26. It is designed to be electrically connected just by inserting it inside.

As shown in FIG. 4, the connecting portion 26 has a blade receiving spring shape, and as shown in FIG. It can also be formed so as to be folded back into a box shape so that its tip can hold and hold the insertion pin. Figure 4 (C
), one of the holding pieces 26a can be folded back to form a flat V-shape to form the pressing-type connecting portion 26, and as shown in FIG. 4(C), the connecting portion 26 can be It may be formed from two holding pieces, and a star-shaped bite hole 29 may be formed in the folded holding piece 26a.

The connecting piece 8 has the contact piece 13 and the connecting portion 26 integrated into one piece, but as shown in FIG. 5, it may be of a type in which they are connected separately. In addition to being assembled as individual pieces, the connecting pieces 8 can be constructed so that the connecting pieces 30 can be separated and assembled as a unit in which a plurality of connecting pieces 30 are connected in a hoop shape, as shown in FIG. You may.

The insertion pin 28 is as shown in FIG.
The terminal board 23 can have a rectangular cross section, a round shape as shown in FIG. 7 (BL), or a polygonal shape such as a hexagonal shape as shown in FIG. 8th
As shown in the figure and FIG. 9, it may be attached to a square terminal plate attachment plate 1-31.

In this way, the connecting part 26 of the connecting piece 8 and the terminal plate 23 are connected in an insertion type by the elasticity of either of them, so the connecting piece 8 can be inserted into the insert body 7 and connected to the outlet. The terminal board 23 is set in the body 1, and the assembly is completed by simply assembling the terminal board 23 into the outlet body 1 and inserting the insertion pin 28 into the connecting part 26. This makes assembly very easy, especially between the connecting piece 8 and the terminal plate 23.
connection becomes very easy. Furthermore, since the terminal board 23 is directly connected to the connecting piece 8 without using a lead wire, there is no risk of incorrect wiring. According to the above connection method, the terminal board 23 can be incorporated in the same direction as the modular insert 6, so there is an advantage that automatic assembly is also possible.

In each of the above-mentioned embodiments, a receiving part is provided on the connection piece 8 side, but the terminal plate 23 side may have a receiving shape such as a blade receiving spring shape.

〔Effect of the invention〕

As seen above, the wiring device according to the present invention is provided with a connecting piece inserted through an insert body having an insertion hole with one end open, and a connecting part provided at one end of the connecting piece. A contact piece located in the insertion hole and provided at the other end of the connection piece bendably protrudes from the insert body to form a modular insert, and the modular insert is inserted through an attachment/detachment opening opened at one end. The contact piece is set in the outlet body so that it fits into the plug insertion opening formed in the outlet body, and the terminal plate, which is separate from the connection piece, is inserted into the attachment/detachment opening. In the wiring device, which is inserted into the outlet body through the outlet body and connected to the connection part, the connection part of the connection piece and the terminal plate are connected in a plug-in manner by the elasticity of one of them. It is characterized by
Assembling becomes easier, costs can be reduced, and there is no risk of incorrect wiring.
