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, Japanese Patent Application Laid-Open No. 55-367
No. 0 has been proposed. This device attaches a semiconductor for dimming control, a dimmer case, etc., and radiates heat generated by the semiconductor for dimming control to the outside.
In addition, in order to attach the dimmer to a wiring box, etc., a dedicated mounting frame was required.

(Problems to be Solved by the Invention) However, as described above, the above-mentioned conventional devices require a dedicated frame for mounting, and the size of the case is generally large. Therefore, use in arbitrary combination with a general-purpose wiring device has not only not been considered, but has also been impossible.

For this reason, it was always used only as a special type.

On the other hand, the so-called large boss type as a continuous wiring device,
For example, it is already known as seen in Japanese Utility Model Application Publication No. 50-125797. 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 a semiconductor for dimming control, which is a heat generating component, and a terminal device, there is a problem in that it becomes difficult to mount the circuit components and the crystallinity of the terminal device increases.

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. This problem is further compounded by the fact that the entire case must be made considerably smaller in order to allow three devices to be used in series, which makes mounting the circuit components even more difficult and requires measures against temperature. Therefore, if one attempts to simply miniaturize the conventional device described above, the terminal device is biased toward one side in the short side direction of the dimmer case, so this terminal device takes up space. Therefore, the variable resistor is mounted on the other side in the short side direction.

As a result, the operation parts are also placed 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. It turns out.

In addition, if the conventional device described 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 frame while housing the semiconductor for dimming control inside this case. It is difficult to assemble as it has to be screwed into place.

The present invention accommodates a variety of wiring needs by configuring a built-in dimmer to have the same installation size as a continuous wiring device, so that the dimmers can be installed not only with each other but also with a general-purpose continuous wiring device in combination. In addition, the operation unit can be placed in the center of the boss despite its small size, so even if two or three units are used together, it will be difficult to use other adjacent dimmers or dimmers. It is not difficult to operate because it is close to the operation part of the wiring device, and the wiring can be done in the same way as other wiring devices by aligning it to one side of the long side of the elongated case. Another object of the present invention is to provide an embedded dimmer in which the influence of heat generation of a semiconductor for dimming control on a terminal device is reduced.

[Structure of the Invention] (Means for Solving the Problems) The present invention has a pair of mounting holes at both ends for mounting to the embedded box and a pair of screw holes for mounting the plate, and an elongated screw hole at the middle part. The device mounting has a window hole, and the device mounting has three sets of device fixing means in the window hole.The continuous mounting is capable of selectively mounting on the frame, and a flush plate is installed in the plate mounting screw hole. This format is used in combination with the following, and is characterized by having the following configuration. In other words, the continuous mounting on both sides of the top surface in the longitudinal direction is in contact with the back surface of the frame, and the dimension in the short side direction is approximately 1/3 of the longitudinal direction of the window hole, and the top surface A case that has a boss part that protrudes in the height direction at the center. A dimmer main body housed in the case, including a variable resistor and a dimming control section disposed on one side of the variable resistor and offset to one side in the longitudinal direction of the case. A terminal device disposed biased toward the other side in the longitudinal direction of the case. An operating section that is disposed on the boss section and controls the variable resistor. For continuous installation, installation in which the frame is fixed is a means,
Be prepared.

(Function) In the present invention, a dimmer is assembled by housing circuit components, a dimming control section, and a terminal device in a case, disposing an operating section in a boss section, and installing means for mounting. To embed this in a wall, attach a common fixture that allows for general use to the frame, and then attach the frame to the wiring box. Furthermore, a flush plate that allows for further versatility can be attached to the frame for mounting the device. 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.

Roughly speaking, the semiconductor for dimming control is placed on one side of the variable resistor and biased towards one side in the longitudinal direction of the case, and the terminal device is placed biased towards the other side in the longitudinal direction of the case. Therefore, an excessive rise in temperature of the terminal device due to heat generated by the semiconductor is prevented, and the variable resistor can be easily arranged, thereby making it easy to arrange the operating section in the center of the boss section.
