Hereinafter, the present invention will be explained in detail with reference to the drawings showing embodiments thereof.

FIG. 1 shows a telephone outlet as an example of a wiring device according to the present invention. Outlet body 1'
does not have a front cover to cover the front surface, and consists only of a block-shaped, integral member corresponding to the housing. As shown in Figure 2, the outlet body 1' is
It is formed of a hexahedron having a front wall 30, a top wall 31, etc., and is embedded and attached so that a part thereof is exposed from an embedding opening 33 of a mounting wall 32 marked with a two-dot chain line. The outlet body l' is provided with a rectangular opening 34 at the center of its front wall 30 and a plug insertion opening 35 located on the back side thereof. Said opening/closing opening 3
4 can be opened and closed by a front cover 37 that can be stored in a cover insertion opening 36 formed inside the bottom side of the body I'. The plug insertion port 35 is also formed in a square shape, and the modular plug 18 provided at one end of the modular cord 17 is inserted into the plug insertion port 35. The other end of the modular cord 17 is connected to a telephone via another plug (not shown). A piece set hole 38 is formed inside the outlet body l' and can be opened and closed by a rear cover 39. The connection piece 40 is made of a spring plate, and is formed so that a contact piece 41 at one end and a connection terminal section 42 at the other end are integrally connected by a conductive section 43 located between them. As shown in FIG. 3, the conductive part 43 of the connecting piece 40 is formed by a slightly wide part, and an L-shaped fitting part 43a having a narrow width is integrally provided at the front end of the conductive part 43. . The conductive part 43 is
It is arranged in the piece set hole 38 so as to be directly abutted against the lower inner surface of the upper wall 31 . The fitting portion 43a is arranged so as to fit into a portion of an inner corner 44 of the upper front surface formed by the top wall 31 and the front wall 30. From one end of this fitting part 43a,
The contact piece 41 extends gradually downward toward the rear cover 39.

The tip of this contact piece 41 is adapted to be received by the back slope 45a of a triangular stopper 45 that projects upward from the bottom into the piece setting hole 38, and the contact piece 41 is configured such that its tip is received by the back slope 45a of a triangular stopper 45 that projects upward from the bottom. The portion extends into the plug insertion port 35 and is electrically connected to the plug 18. Meanwhile, the connection terminal portion 42 is formed at the upper rear end of the connection piece 40. This connection terminal section 4
2, a presser extending downward from the rear end of the conductive portion 43 is provided to be connected to the receiving piece 42a and an intermediate portion of the conducting portion 43, and the presser extends diagonally in the direction of the receiving piece 42a. The retainer made of a spring plate consists of a protrusion (lock spring) 42b. As shown in FIG. 1, the holding piece 42a is configured such that its lower side is fixed to the rear cover 39. An elongated wire insertion hole 46 is formed at the rear end of the conductive portion 43, and the wire is inserted near the rear end of the top wall 31 of the outlet body 1'' so as to correspond above the wire insertion hole 46. A mouth 47 is formed. This electric wire insertion port 47 is formed in a stepped shape, and its center is set to face at right angles to the plug insertion direction (arrow H). Each mold 'a48 is inserted into the wire insertion port 47 from above, and the wire terminal 4
8a is pressed against the connection terminal portion 42 by a spring force to be connected. In addition, the above connection piece 4
In the embodiment, six connection pieces 40 are installed in parallel, and these connection pieces 40 are held in the piece set hole 38 in the outlet body 1' by being pushed from the back by the rear cover 39.

In the wiring device configured as described above, the wire insertion port 47 is provided so as to intersect with the plug insertion direction H, so the wire tightening screw 22, washer 20, spring Since no installation space is required for the washer 21, etc., the device can be made compact so that the depth dimension W is sufficiently small. As shown in FIG. 2, this compact design has the advantage of streamlining construction, since it is easy to embed and fit the fixture even if the embedding space is small. Moreover, in the above embodiment, the wire insertion port 47 is oriented at right angles to the plug insertion direction H, so there is no need to bend the lead terminal for connection as in the conventional case, and the lead terminal can be left straight. Terminal 48a can be connected. This not only makes the construction more efficient, but also has the advantage that troubles such as the lead terminals 48a themselves coming off are less likely to occur. In the embodiment described above, since the electric wire 48 is inserted from above, there is also the advantage that the electric wire 48 is difficult to pull out after construction. Furthermore, in the embodiment described above, the connection piece 40 is made of a spring plate, and the connection terminal portion 42 is made of a spring plate, so that
It is very advantageous in that the electric wire 48 can be connected with a so-called one-touch operation, and since the connecting piece 40 includes everything from the contact piece 41 to the connecting terminal part 42, the number of parts is small. As a result, it is possible to reduce costs and provide a device that is advantageous for insertion and disassembly.The plug insertion port may be arranged on another side wall of the outlet body. Although the connection terminal portion is formed of a spring plate, it may be of a conventional screw type. Although the connecting piece is an integral spring plate, it can also be of a type having a lead wire in the middle as in the conventional example. Although the front cover is of an openable/closable type, it can also be configured as a fixed front cover as in the conventional example. However, if an openable/closable front cover is provided as in the embodiment described above, compactness can be achieved more effectively. Although the above-mentioned presser is of a type in which the projecting piece is joined, it may be formed by being bent integrally with the connecting piece.
