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, this type of dimmer requires a special structure for the purpose of dissipating the heat generated inside to the outside. For installation in wiring boxes etc.
It was equipped with a special mounting frame. Additionally, the size of the case is generally large. Therefore, it has not only not been considered, but also impossible, to use it in arbitrary combination with a general-purpose wiring device.

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.

It was discovered that there were technical problems when attempting to use a built-in dimmer as a large boss-type continuous wiring device. In other words, this type of dimmer uses a variable resistor in the dimmer body to change the dimming intensity, so in order to place the operation part in the center of the boss part, the variable resistor must be placed in the center inside the case. There is a need to.
However, since the case also accommodates a 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. 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.

(Problems to be Solved by the Invention) The present invention configures a built-in dimmer to have the same installation size as a serial wiring device, so that the dimmers can be freely combined not only with each other but also with a general-purpose wiring device. In addition to being able to meet a variety of wiring needs, the operation unit can be placed in the center of the boss despite its small size. To provide a built-in type dimmer that does not spoil the appearance due to misalignment of parts, allows wiring to be aligned on one side, and has good installation workability.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a pair of mounting holes and a pair of plate mounting screw holes that can be mounted to an embedded box at both ends, and an elongated instrument in the middle part. The device has a mounting window hole and can be selectively mounted to a continuous mounting frame comprising three sets of device fixing means in the device mounting window hole, and in combination with a flash plate attached to the plate mounting screw hole. This dimmer is used, and is further characterized by having the following configuration. In other words, both sides of the upper surface in the long side direction are in contact with the back surface of the continuous mounting frame,
The case has a dimension in the short side direction that is approximately 1/3 of the longitudinal direction of the instrument mounting window hole, and also has a boss portion projecting in the height direction at the center of the upper surface. The dimmer main body is made up of a circuit assembly that mounts the necessary circuit components for dimming the light source, which is a load, housed in the case. A terminal device disposed biased toward one side in the long side direction of the case. An operation section that is disposed on the boss section and controls the operation of the dimmer main body. 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 body and the terminal device are housed in the case, the operating part is arranged in the boss part, and the mounting means is attached to assemble the dimmer. To bury it, attach it to a multi-use fixture mounting frame that allows for general-purpose use, and then attach the mounting frame to a 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. 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 direction of the case, it is easier to arrange the circuit components of the dimmer main body, especially the variable resistor, and this makes it possible to place the operation part in the center of the boss part. This makes it easier to set up.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention.
In the figure, 1 is a built-in dimmer of the present invention, which includes a case 2 and a dimmer main body 3 housed in the case.
and a terminal device 19 disposed biased to one side in the long side direction of the case 2, an operating section 4 for controlling the operation of the main body 3, and the case 2 mounted on a continuous instrument mounting frame 5 shown in the third figure. and a fixing means 6 for fixing. The device mounting frame 5 has a pair of mounting holes 7 with mounting pitches that can be mounted to a wiring box (not shown) buried in a wall surface, and a pair of plate mounting screw holes 8 at both ends. In addition, there is an elongated instrument mounting window hole 9 in the middle part.
and three sets of instrument fixing means 1 arranged in this window hole 9.
0 is allowed.

The case 2 of the dimmer 1 consists of a body 12 whose short side dimension is approximately 1/3 of the length of the device mounting window hole 9, and a cover 15 fitted to the body 12. . A boss portion 13 is formed at the center of the upper surface of the cover 15 . Note that the present invention is not limited to such a specific structure; for example, it may consist of a body with an open bottom surface and a cover that covers the bottom surface, and the boss portion may be formed on the top surface of the body. Further, the body may be divided into two in the vertical direction.

The dimmer main body 3 consists of a circuit assembly mounted with necessary circuit components for dimming a light source (not shown) as a load, and includes a thyristor 17 and a variable resistor 18 on a printed wiring board 16. and other circuit components are mounted to form, for example, a phase control circuit. The terminal device 19 functions so that the dimmer of the present invention is connected in series between a power source and a load (not shown).

The operation section 4 is arranged on the boss section 13. In this embodiment, it is a rotary knob, but it may be a lever or any other structure as long as it has an operation function.

The attachment means 6 is used to attach the dimmer 1 to the attachment frame 5 in cooperation with the appliance fixing means 10 of the continuous appliance attachment frame 5. In this embodiment, a coupling fitting 20 for coupling the body 12 and the cover 15 is used.
Although the attachment means 6 is constituted by a frame-shaped portion integrally formed with the attachment means 6, the attachment means 6 is not limited thereto.

Various known means can be used as the appliance fixing means 10, but in the third illustrated embodiment, a protrusion 21 that engages with the appliance attachment means 6 of the dimmer 1, and a protrusion 21 adjacent to the protrusion 21 are used as the appliance fixing means 10. It is composed of a caulking operation section 22. In this case, the caulking operation section 22 on one side of each set of means may be omitted.

4 to 6 illustrate an example of how the dimmer of the present invention is used. In other words, in Figure 4, 2
The dimmers 1, 1 are mounted on a mounting frame with an interval corresponding to one dimmer, and boss portions 13, 13 protrude from boss holes 23, 23 of a flash plate 24, respectively. In FIG. 5, one dimmer 1 of the present invention is connected to two switches 25, 25, and is used by sharing one common boss hole 23' of the three flash plates 24'. ing. In Figure 6,
One dimmer of the present invention has a flash plate of 24″
It is attached to the central boss hole 23''.

[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 devices are stored off-centered to one side in the long direction of this case, up to three terminal devices can be attached to one device mounting frame alone or in any combination with connected wiring devices, and can also be used in a compact size. regardless of,
Since the layout of the dimmer main body, which is made up of a circuit component mounted with necessary circuit components for dimming the light source, is facilitated, it becomes easy to arrange the operating section in the center of the boss section. Therefore, even if the top and bottom are installed in the wrong way, the position of the operation part will not be misaligned and the appearance will not be spoiled. Furthermore, since the wiring can be aligned on one side, it is possible to provide a built-in dimmer with good installation workability.
