Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an embedded wiring device, such as an outlet or a switch, which is used by being attached to an embedded wiring box.

As shown in FIG. 1, the conventional embedded wiring device is assembled by crimping and fixing the device stand 20 housing the terminal and the lid body 21 together with the assembly fittings 22, and then assembling the device. , the wiring device was further crimped and fixed to the mounting bracket 23 and attached to the wiring box 24 buried in the wall via the mounting bracket 23, but during the assembly process, parts such as the assembly bracket 22 and the mounting bracket 23, etc. The assembly work is complicated as it requires a swaging jig to swage these, and it also requires a mold and a press machine to punch out the assembly fittings 22 and mounting fittings 23 necessary for assembly, and the embedded wiring Not only does manufacturing the device require a large amount of equipment costs, but since the assembly fittings 22 and mounting fittings 23 are made of iron, there is a risk that they will rust and corrode due to moisture, etc., inducing electrical and mechanical accidents. There were many problems such as:

The present invention has been made in view of the above points, and an embodiment illustrating the same will be described below. In FIGS. 2 and 3, reference numeral 1 denotes a lid body made of flexible synthetic resin, etc.; Attachment plates 3, 3 are integrally molded on both sides of a rectangular protrusion 2 formed in , and a long hole 4 and a screw hole 5 are bored in the attachment plates 3, 3, respectively. 6 is a fitting opening having a tapered wall surface 6a formed in the bottom surface of the rectangular protrusion 2 of the lid body 1;
Reference numerals 7 and 7 designate locking plates formed by integrally protruding from both side walls of the rectangular protrusion 2, and the tip thereof has an inclined surface 7.
A hooking portion 7a having a shape of b is provided. Reference numeral 8 denotes a device stand made of synthetic resin; 10 is a frame having an inclined side surface 10a provided at the opening edge of the terminal storage chamber 9 of the device stand 8; the frame body 10 connects the lid body 1 and the device stand 8; When assembled in one piece, as shown in FIG.
This prevents looseness between the container base 8 and the lid 1.
Reference numerals 11 and 11 denote locking protrusions having sloped top surfaces 11a protruding from both side walls of the table 8;
1, the locking portions 7a of the locking plates 7, 7 having the inclined surfaces 7b at the tips provided on the lid 1 are connected to the locking plates 7, 7.
The recessed wiring device is assembled by forcibly fitting and locking the lid body 1 and the device base 8 together with one touch as shown in FIG. 4, against the elasticity of the As shown in FIG. 5, the mounting plates 3, 3 of the lid 1
The wiring box 12 is installed by inserting screws into the long holes 4, 4 drilled in the wall and screwing them into the wiring box 12 buried in the wall surface. In FIG. 6, locking plates 7, 7 are provided integrally projecting below both end side walls of the rectangular protruding portion 2 of the lid 1, and the tip end locking portions 7a of the locking plates 7 are attached to the both end side walls of the utensil stand 8. This figure shows another embodiment of the present invention, in which the lid body 1 and the container stand 8 are fitted and locked together by forcibly locking the locking protrusions 11 and 11 provided on the respective sides. It is an explanatory view of a built-in wiring device. Note that the tip end latching portion 7a of the latching plate 7 provided on the lid body 1 may be provided with both ends thereof rising upward at right angles, as shown in FIG. In addition, numeral 13 in the figure is a decorative board that can be placed over the embedded wiring device.

According to the present invention, as described above, the tip end latching portion 7a of the latching plate 7 is integrally provided below both side walls of the rectangular protruding portion 2 of the lid body 1 made of flexible synthetic resin. is forcibly locked to the locking protrusions 11 provided on both side walls of the holder 8, and the holder 8 and the lid 1 are fitted and fixed together to assemble the embedded wiring device. Not only can the embedded wiring device be assembled easily and quickly with one touch without the need for tools, but when the device base 8 and the lid 1 are assembled together, the rectangular protrusion 2 of the lid 1 can be easily and quickly assembled. Since the inclined side surface 10a of the frame 10 provided at the edge of the opening of the terminal storage chamber 9 of the device stand 8 is fitted into the fitting opening 6 having the tapered wall surface 6a formed in the bottom surface, the device stand 8 and the lid are connected to each other during use. There is no risk of looseness occurring between the lid body 1 and the wiring box 12 buried in the wall surface. It can be easily installed by simply screwing both ends of the , and there is no need for any assembly or mounting hardware as in the past, so there are no overhead costs for these assembly parts or the molds and press machines used to manufacture them. It has excellent effects such as being able to save a large amount of energy, and moreover, there is no risk of inducing electrical and mechanical accidents due to corrosion of iron assembly fittings and mounting fittings.
