Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly suitable for connecting to an outlet, especially a plurality of plugs, which is embedded in a wall surface of a room and supplies power to an electric device by connecting the plug of the electric device. It is about outlets.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 9, a wall surface 3 has an outlet 2a for connecting a plug 1a of an electric device as a means for supplying electricity to an electric device used indoors.
It is located at a.

This outlet 2a is an outlet body 4
to the blade terminal 6a to which the insertion blade 5a of the plug 1a housed in a is connected, and to the blade terminal 6a formed on the surface 8a of the plate 7a arranged to cover the surface of the outlet body 4a. A plug connecting portion 10a formed by the insertion opening 9a of the insertion blade 5a communicating therewith is formed.

Since the plug connecting portion 10a is formed along the surface 8a of the plate 7a as described above, the connected plug 1a largely projects to the wall surface 3a, especially on the front surface of the outlet 2a. When equipment or furniture is installed, there is a problem that a large gap is formed between the equipment and furniture and the room cannot be effectively used.

Recently, it has been required to use a large number of devices at the same time, such as video and audio devices and computers, and as a means for supplying electricity from a single outlet, for example, as shown in FIG. The tap 12a having the plug connecting portion 11a of 1 was used.

However, when the plug connecting portion 3a is added by using the tap 12a, the connected plug 1a further protrudes by the height of the tap 12a and is inserted into the plug connecting portion 10a of the outlet 2a. Since a plurality of plugs 1a are connected to the taps 12a, the taps 12a are easily pulled out, and further, the number of electrical connection points increases, so that the contact resistance increases and the probability of connection failure increases. There was a problem that connection might not be possible.

[0007]

The problem to be solved by the present invention is that the conventional outlet is not suitable for connecting a plurality of plugs, as the connected plugs largely project to the surface side. It is a point.

[0008]

According to the present invention, a lid body which covers the surface of an outlet main body is formed into a box shape having a predetermined height with an opening on the back surface, and a plug connecting portion is provided along a side surface of the lid body. This structure solves the problem that the connected plug largely projects to the front side, and has a predetermined height with the back surface of the lid body that covers the front surface of the outlet main body opened. The box-shaped structure is formed along the side surface and the top surface of the box, so that reliable electrical connection can be achieved even if a plurality of plugs are connected.

[0009]

The function is such that the plug is connected to the plug connecting portion formed along the side surface of the lid body having a predetermined height, and the connected plug may project to the surface side more than the height of the lid body. Absent.

[0010]

Embodiments of the present invention will now be described with reference to the drawings.

1 to 8 show an example in which the present invention is applied to a wall-mounting type outlet having a plurality of connection ports, and mainly a receiving blade terminal to which the inserting blade 11 of the plug 1 is connected. An outlet main body 3 accommodating a terminal portion 2 such as 21; a lid body 4 arranged to cover the surface of the outlet main body 3; An exterior plate 6 covering the surface of the mounting frame 5, a decorative plate 7 arranged between the lid body 4 and the exterior plate 6, and the like.

The lid body 4 to be covered with the outlet main body 3 is formed of a hard synthetic resin having an insulating property into a box shape with an open rear surface, and the insertion blades 11 of the plug 1 are inserted into the left and right side surfaces 41 and 42. Two insertion ports 43, 43 formed by two insertion ports are provided side by side in the longitudinal direction, and the top face 44 has the insertion port 4 at the center.
5 is formed.

This lid body 4 has a height h slightly longer than the thickness 1 of the plug 1 to be connected, and the outlet body 3
They are fixed to each other by setscrews 31, 31 inserted from the rear surface side.

Further, the terminal portion 2 housed in the outlet main body 3 corresponds to the insertion openings 43, ... 43 and 45 formed on the left and right side surfaces 41, 42 and the top surface 44 of the lid body 4. Five sets of blade terminals 21, 21 are projected from the top surface of the outlet main body 3, and two pairs are provided along the left and right side surfaces 41, 42 of the lid body 4 and the top surface 4 respectively.
A total of five connecting portions 8 are formed along the line 4.

Each of the blade receiving terminals 21 is composed of a conventionally known plate-shaped blade receiving portion and a blade receiving spring arranged to face the blade receiving portion.
As shown in FIG. 8, it is composed of two terminal members 24 and 25 integrally formed with receiving blade terminals 21 having different polarities, and the terminal member 2 is provided on the back surface of the outlet body 3.
The connection terminals 26 and 27 are arranged so that the connection ends of the electric wires can be attached and detached without using the conventionally known screws respectively connected to the wires 4 and 25.

Further, in the drawings, reference numeral 9 is a metallic reinforcing frame which is arranged on the surface of the mounting frame 7 and overlaid with the exterior plate 6.

In this embodiment having the above-mentioned structure, it is mounted on the wall surface through mounting holes 71 and 82 formed so as to communicate with the mounting frame 7 and the reinforcing frame 8 similarly to the conventional outlet.

In this embodiment mounted on a wall surface, five connection ports 8 are exposed on the surface, and at least five electric devices are connected without using a tap having a plurality of connection portions as in the conventional case. It is possible.

Particularly, when the plug 1 is connected to the plug connecting portion 8 formed along the side surface 41 or 42 having the predetermined height h of the lid body 4, the height of the lid body 4 is h. Since it does not project to the surface side above, it is possible to use the indoor space extremely effectively, and even when installing equipment or furniture in front of the outlet, no large gap is formed with the wall surface. .

Further, since a tap having a plurality of connecting portions is not used unlike the conventional case, the inserting blade 11 of each plug 1 does not project further by the height of the tap, and each receiving blade terminal has each receiving blade terminal. Since it is securely pressed against and held at 21, there is no need to worry about it coming off as when using a tap.

Furthermore, there is no concern about an increase in contact resistance and a connection failure due to an increase in the number of electrical connection points due to the use of taps.

In particular, the present embodiment uses the two terminal members 24 and 25 which are integrally formed for each of the blade terminals 21 having different polarities, so that manufacturing and management of parts are extremely easy.

In this embodiment, the plug connecting portion 8 has a lid 4
The left and right side surfaces 41, 42 are provided with two pieces each, and the top surface 44 is provided with one piece.
1, 42 and the number of plug connection portions 8 provided on the top surface 44 do not matter.

Further, the plug connecting portions 8 may be provided on the upper and lower side surfaces of the lid body 4, and in particular, if not necessary, the top surface 44 is not provided with the plug connecting portions 8, and at least one plug connecting portion 8 is provided on one side surface. A configuration in which one plug connection portion 8 is provided may be used.

Of course, in a special case where more power supplies than the number of installations are required, the tap can be used as in the conventional case, and the height of the lid body 4 can be connected to the plug connecting portion 8. By setting the height, taps can be connected to the side surfaces 41 and 42.

Further, although the present embodiment has been described with respect to the wall-mounted outlet, it goes without saying that the same can be applied to an outlet connected to the end portion such as an extension cord.

[0027]

According to the present invention, it is possible to provide a larger number of plug connection ports as compared with the conventional outlet having a plurality of plug connection ports. It is possible to connect at least 5 electric devices without using them.

In particular, when the plug is connected to the plug connection portion formed along the side surface of the lid body having a predetermined height, the plug does not protrude beyond the height of the lid body to the surface side. Therefore, the indoor space can be used very effectively, and even when equipment or furniture is installed in front of the outlet, no large gap is formed with the wall surface.

Further, since a tap having a plurality of connecting portions is not used unlike the conventional case, the plug is further protruded by the height of the tap, and each plug is securely held in pressure contact with each receiving blade terminal. There is no worry of coming off.

Furthermore, there is no concern about an increase in contact resistance due to an increase in the number of electrical connection points due to the use of taps and a connection failure.

In addition, it can be attached to the wall surface like a conventional outlet.
