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 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 conventional devices require a dedicated mounting frame, and the size of the case is generally large. Therefore, not only has it not been considered, but it has been completely impossible to use it in arbitrary combination with a general-purpose wiring device.
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 Publication 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 houses the semiconductor for dimming control, which is a heat-generating component, and the terminal device, it becomes difficult to mount the circuit components, and the heat generated by the semiconductor causes the temperature of the terminal device to rise to the JIS and other standards. There is a problem with coming off. This is because terminal devices are extremely sensitive to heat. 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 an attempt is made to simply miniaturize the above-mentioned conventional device, it is particularly susceptible to thermal effects.
The present invention provides a built-in dimmer in which the built-in dimmer is configured to have the same installation size as a continuous wiring device, and the influence of heat generated by a semiconductor for dimming control on a terminal device is reduced. The purpose is to

[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 storage section that has an opening in the body that is biased toward one side in the long side direction and faces the opening, and is partitioned by a partition wall that separates the storage section from an adjacent storage section. A wiring board, a variable resistor provided on the wiring board, dimming control parts such as a semiconductor for dimming control, and a terminal device attached to one end of the wiring board facing the terminal device housing part. These are integrally assembled in advance, and are dropped into the body from the opening side, and the terminal device is arranged in the terminal device storage portion, and other parts are arranged in the storage portion and placed in the case. The stored dimmer body. An operating section that is disposed on the boss section and controls the variable resistor. and attachment means for fixing the case to the multiple mounting frame in cooperation with the fixing means of the multiple mounting 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-use fixture mounting frame that allows for general use, and then attach the mounting frame to a wiring box. and,
Furthermore, a flash plate that allows general use 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 placed in the terminal storage compartment that is separated from the adjacent storage compartment by biasing it to one side in the long side of the case, it is heated by the partition wall, and the semiconductor Excessive temperature rise of the terminal device due to generated heat is prevented and miniaturization becomes possible. Furthermore, by integrating the main body of the dimmer, which includes the wiring board, dimming control parts, and terminal device, in advance, and dropping this into the body from the opening side,
Since it can be assembled into the case, the ease of assembly is greatly improved.

[Effects of the Invention] The present invention is configured as detailed above, and in particular, the dimension of the case in the short side direction is formed to be approximately 1/3 of the longitudinal direction of the elongated instrument mounting window hole of the continuous mounting frame,
Since the terminal device is installed in the terminal device storage area that is separated by a partition wall that separates it from the adjacent storage area on one side of the long side of the case, the heat from the dimming semiconductor is blocked by the partition wall. This prevents the temperature of the terminal device from rising too high and allows for easy miniaturization. Further, since the wiring can be aligned on one side in the long side direction like other wiring devices, it is possible to provide an embedded dimmer with good installation workability.
