Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an embedded dimmer that can be used by being attached to a wiring box embedded in a wall surface or the like.

(Prior art) Conventionally, as this type of dimmer, for example,
The one in Publication No. 3670 has been proposed. This device attaches a semiconductor for dimming control, a dimmer case, etc., dissipates the heat generated by the semiconductor for dimming control to the outside, and attaches the dimmer to a wiring box, etc. For this purpose, a special mounting frame was attached.

(Problems to be Solved by the Invention) However, as described above, the above-mentioned conventional devices require a dedicated mounting frame, and the size of the case is also generally large. Therefore, not only has it not been considered, but it has also been impossible to use it in arbitrary combination with general-purpose wiring devices.
For this reason, it was always used only as a special type. In addition, to assemble the dimmer, the semiconductor for dimming control is screwed to the heat sink and mounting frame, the dimmer case is separately screwed to the mounting frame, and the cover (decorative board) is screwed to the mounting frame. Since the dimmer is attached to the mounting frame, the workability of assembling the dimmer is poor.

On the other hand, the so-called large boss type as a continuous wiring device is already known as seen in, for example, Japanese Utility Model Application No. 125797/1983. However, it has been found that there are technical problems when attempting to simply convert the conventional built-in dimmer into a large boss type common wiring device. That is, since this type of dimmer uses a variable resistor to change the degree of dimming, it is necessary to arrange the variable resistor at the center inside the case in order to arrange the operating section at the center of the boss section. However, since the case also accommodates the terminal device, there is a problem in that it becomes difficult to mount circuit components. This is because the terminal device is relatively large in size compared to other circuit components and is therefore extremely susceptible to the position of the terminal device. And this problem is further
In order to allow three units to be used in series, the entire case must be made considerably smaller, which makes mounting the circuit components even more difficult. Therefore, if you simply try to downsize the conventional device mentioned above, the terminal device is biased toward one side of the short side of the dimmer case, so this terminal device takes up space. As a result, the variable resistor is mounted biased toward the other side in the short side direction. As a result, the operation parts are also installed unevenly, and if two or three of them are used in succession, the problem arises that they are difficult to operate because they are close to the operation parts of other neighboring dimmers or wiring devices. .

In addition, if the conventional device mentioned above is miniaturized as it is, after incorporating the variable resistor, terminal device, etc. into the miniaturized case, the case can be attached to the mounting frame while the semiconductor for dimming control is housed inside the case. It must be secured with screws, making assembly work difficult.

The present invention configures a built-in dimmer to have the same installation size as a continuous wiring device, so that the dimmers can be connected not only to each other, but also to a general-purpose continuous wiring device in combination, making it possible to meet a variety of wiring needs. In addition, it is possible to place the operation part in the center of the boss part despite the small size, and therefore, the
Even if one or three units are used together, it will not be difficult to operate because they are in close proximity to the operation parts of other neighboring dimmers or wiring devices, and the wiring can be connected to one side of the long side of the elongated case. It is an object of the present invention to provide a built-in dimmer that can be installed in the same way as other wiring devices and has good workability in assembling and attaching the dimmer body.

[Structure of the Invention] (Means for Solving the Problems) The present invention has a pair of mounting holes and a pair of plate mounting screw holes at both ends that can be mounted to an embedded box, and an elongated instrument mounting window in the middle part. It has a hole and can be selectively attached to a continuous mounting frame comprising three sets of instrument fixing means in the instrument mounting window hole, and is used in combination with a flash plate attached to the plate mounting screw hole. It is characterized by having the following configuration. That is, it consists of a body with an open top side, and a cover that has a boss portion protruding in the height direction at the center of the top surface and closes the opening of the body, and when these body and cover are combined, it forms an elongated box. It is mounted on the multiple mounting frame with both sides of the upper surface in the long side direction in contact with the back surface of the multiple mounting frame, and the dimension in the short side direction is approximately 1/3 of the longitudinal direction of the instrument mounting window hole. Case formed. A terminal device accommodating portion is formed in the body so as to be biased toward one side in the longitudinal direction of the body. A wiring board, a dimming control component such as a variable resistor provided on the wiring board, and a terminal device attached to one end of the wiring board facing the terminal device housing, and these are integrated in advance. The dimmer body is assembled into a dimmer, and is dropped into the body from the opening side and housed in the case. Arranged in the boss part above,
An operation unit that controls the variable resistor. Attachment means cooperates with the fixing means of the multiple attachment frame to secure the case to the multiple attachment frame.

(Function) In the present invention, the dimmer is assembled by housing the dimmer body previously assembled integrally in the case, arranging the operation part in the boss part, and attaching the mounting means. To embed it in a wall, attach it to a multi-purpose fixture mounting frame that allows for general-purpose use, and then attach the mounting frame to the wiring box. Then, a flash plate that allows for further versatility may be attached to the instrument mounting frame. In this way, the dimmer of the present invention can be mounted on a wall in the same way as a continuous wiring device. Therefore, up to three dimmers can be installed in series. Furthermore, it is possible to install a dimmer and a continuous wiring device in combination as necessary.

Furthermore, since the terminal device is arranged biased to one side in the long side direction of the case, it is easier to arrange the dimming control parts, especially the variable resistor, and this makes it possible to arrange the operation part in the center of the boss part. becomes easier.

Furthermore, the main body of the dimmer, which includes a wiring board, dimming control parts, and terminal device, is integrated in advance, and it can be integrated into the case by dropping it into the body from the opening side. So,
The ease of assembly work is greatly improved.
