Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wiring device having a connection portion such as a ground terminal.

[Background technology]

FIG. 1 shows a cross-sectional view of the installed state of a conventional electrical outlet with a ground terminal. In the figure, 1 is a body disposed in a recess for attaching an outlet with an earth terminal provided in a wall surface 2, and 3 is a cover thereof, and both constitute a main body 4 of the appliance. 5 is a decorative plate, and 6 is a terminal plate having a U-shaped cross section. This terminal board 6 is connected to the cover 3
It is attached to the body 1 with its U-shaped vertical side exposed through the earth terminal hole provided in the body 1.

7 is an earth terminal screw whose head is formed into a knob 14 and is equipped with a washer 8, which is fitted into a screw hole 9 provided on the vertical side of the terminal plate 6, and the washer 8 and the vertical side of the terminal plate 6 are screwed together. A ground wire (not shown) is sandwiched between the two. The earth terminal screw 7 and the terminal plate 6 constitute an earth terminal. 10 is a locking spring, 11 is a ground wire stopper that stops the tip of the ground wire, 12 is an electric wire insertion hole, and 13 is a plug blade insertion port for inserting a plug blade of an electric appliance, etc.; A blade receiving portion (hidden and not visible) corresponding to the insertion port 13 is provided. In this type of cosescent with earth terminal, the knob 14 of the earth terminal screw 7 protrudes from the surface of the cover 3, and the distance l1l11h between the top surface of the knob 14 and the cover surface is approximately IQ.
Since the length is about 1.5 mm, there is a problem that the knob 14 gets in the way and is inconvenient to use when a plug blade (not shown) such as a DC adapter is inserted into the plug blade insertion port 13 of the cover 3. was. Furthermore, since the knob 14 is exposed, it causes a malfunction in which the user accidentally turns the knob 14 and disconnects the ground wire.

[Purpose of the invention]

An object of the present invention is to provide a wiring device that is easy to use and does not cause malfunction.

[Disclosure of the invention]

The gist of the present invention is a wiring device characterized in that a recess is provided in the device main body, a wiring connection portion is provided in the recess, and a lid is provided to cover the recess so as to be openable and closable. It is something.

Next, the present invention will be explained in detail based on examples.

FIG. 2 is an exploded perspective view of one embodiment of the present invention with the decorative plate removed, and FIG. 3 is a partially cutaway side view of the assembled state. In these figures, 15 is a body, 16 is a ground terminal plate, and has a ground electrode blade receiving spring portion 17. This ground terminal plate 16 and a lock spring 19 are fitted into the body 15 as shown by the chain line. 20 is the lock spring 19
21.22 is the blade receiving spring part 21a, 22a
18 is a locking spring thereof, 20a is an unlock button, and 23 is a cover having a plug blade insertion port 24, 25 and a ground electrode plug blade insertion port 26. The cover 23 is provided with a hole 27 for exposing the ground terminal plate.
The surface of the hole 27 is set to be located within the hole 27. Reference numeral 28 denotes a lid body that covers this hole 27, and is attached to the cover 23 by a rotating shaft 29, and the claw portion 28a on the back surface of the end portion is connected to the locking hole 31 of the lid receiving portion 30 provided on both side surfaces of the hole 27.
By locking the hole 27 (see FIG. 4), the covered state of the hole 27 is maintained. In this covering state,
The surface of the lid body 28 is the same as the surface of the cover 23. 3
2 is a ground terminal screw made of a general electric screw, 33
is the earth terminal washer. The ground terminal screw 32 is fitted into the tapped hole of the ground terminal plate 16, and the ground terminal washer 33
A ground wire (not shown) is sandwiched between the ground terminal plate 16 and the surface of the ground terminal plate 16.

In this configuration, the ground wire can be connected by removing the claw 28a on the back surface of the lid 28 from the locking hole 31 of the lid holder 30.
8 as shown in FIG. 5, and connect the ground terminal screw 32. An earth terminal consisting of a ground terminal plate 16.

It is done by exposing the sterminal. The state after this connection is shown in FIG. In FIG. 6, 5 is a decorative plate.

In this way, the head knob of the ground terminal screw is not exposed on the cover of this outlet unlike in the past, so as shown in Figure 7, devices such as DC adapters (
The IJ (indicated by the chain line) can be easily installed.

FIG. 8 is an exploded perspective view of another embodiment with the decorative plate removed, and FIG. 9 is a partially cutaway side view of the assembled state. In this embodiment, a lid mounting portion 51 is provided on the surface of the cover 23, and a mounting portion 52a of the lid 52 is attached to the shaft 53.
At the same time, a handle-type knob 55 is attached to the cylindrical head screw 54 with a shaft 56, and this serves as a ground terminal screw. Since the other parts are substantially the same as those of the previous embodiment, corresponding parts are given the same reference numerals.

In this embodiment, the ground wire 34 is connected as shown in FIG. 10 by opening the lid 52, raising the handle knob 55 and loosening the screw 54, and then connecting the ground wire 34 as shown in FIG. 34 is positioned between the washer 33 and the surface of the terminal plate 16, and the screw 54 is tightened. As a result, the ground wire 34 is connected as shown in FIG.

This embodiment not only provides the same effects as described above, but also has the effect that the screw 54 can be rotated easily because the handle-type knob 55 can be used to rotate the screw 54.

It goes without saying that the present invention can be applied to connection parts of wiring devices other than receptacles with earth terminals.

〔Effect of the invention〕

Since the wiring device of the present invention is configured as described above, the heads of the wiring screws are not exposed on the cover unlike the conventional devices. Therefore, it becomes possible to easily attach other electric appliances and the like onto the wiring appliance. Furthermore, it is possible to prevent malfunctions such as erroneously operating the wire connection screw and disconnecting the wire.
