Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support structure for a decorative handle of a switch of a wiring device.

[Prior art]

As interior decoration becomes more sophisticated, wiring devices are also required to be of high quality and have excellent operability.

When it comes to switches that have a high-class image and are easy to operate, for example, in terms of design, the color of the plate and handle are unified, and from the point of view of improving operability, the handle is made larger. It can be operated with just a light touch, and it can be operated easily even in dark places.

Therefore, we created a structure that separates the switch handle and the cosmetic handle that engages with this handle.
A switch with a structure that allows smooth reversal operation by increasing the size of the cosmetic handle has already been developed.

In this way, in the case of a structure with a large cosmetic handle, it is necessary to ensure that the switch is reversed no matter which part of the cosmetic handle is pressed. is required.

For example, as shown in FIG. 1, protrusions 51 and 52 are provided on the back surface of the decorative handle 5, and the structure is such that the protrusions 51 and 52 are engaged with the recess 18' and hole 18'' provided in the handle 16 of the switch 8. In this example, if the engaging protrusion 52 is chipped, the engagement between the cosmetic handle 5 and the switch handle 16 will become unstable.

In addition, in the case of the prior art disclosed in Utility Model Application Publication No. 48-93369 ``Switch Operation Body Reversing Device'', a structure in which a decorative handle is supported by a plate frame is disclosed, but as shown in FIG. When attaching the mounting bracket 1 to the switch box 3, if the mounting screw 3a is sufficiently tightened, the mounting bracket may become deformed and the switch handle and the decorative handle may not be able to be connected smoothly. Ta.

[Problems to be Solved by the Invention] The present invention aims to improve the above-mentioned drawbacks, and aims to improve the above-mentioned drawbacks by making it easy to engage the makeup handle and the switch handle, and making it easier to use the switch in a somewhat messy manner. To provide a high-grade wiring device that can withstand the replacement of a cosmetic handle, etc.

[Means to solve the problem]

The present invention will be described in detail below according to one embodiment thereof.

3 to 5, reference numeral 1 denotes a mounting bracket including a switch mounting through hole 2, a through hole 3b for a mounting screw 3a for mounting to the switch box 3,
3b. Reference numerals 4 and 4 are cut and raised pieces that support the decorative handle 5. The cut and raised pieces are integral with the metal fitting and are provided in the longitudinal direction of the metal fitting near each screw through hole for attaching to the switch box. The cut-and-raised piece extends in a direction substantially perpendicular to the longitudinal direction of the mounting bracket, and has a substantially arc-shaped R portion 6 in the center. 7 is a screw hole for attaching the switch 8. 9 is a plate frame, 10 is a decorative plate frame, and 11 is a middle frame. The plate frame 9, decorative plate frame 10, and middle frame 11 form a plate portion. The plate frame 9 and the mounting bracket 1 are positioned by the projections 12 of the plate frame 9 being engaged with the engagement holes 13 of the mounting bracket 1. Note that 14 is a screw hole into which the screw 15 of the middle frame 11 is screwed. That is, the decorative plate 10 is connected by connecting the inner frame 11 and the mounting bracket 1 with the screws 15.

Reference numeral 16 denotes a handle of the switch 8, which is connected to the cosmetic handle 5. As shown in FIG. 5, the handle 16 of the switch 8 has a recess 18, leaving a central protrusion 17, which is fitted and engaged with a cylindrical protrusion 19 provided on the back surface of the decorative handle 5. .

Note that 8b is a fixed contact terminal plate to which a fixed contact 8d is fixed, 8a is a movable contact plate to which a movable contact 8e is fixed, and 8c is a movable contact terminal plate electrically connected to the movable contact plate 8a. Also, the protrusion 1 of the handle 16
The notch 16b provided in the movable contact plate 8a
The movable contact plate 8a is swung by the swinging of the handle 16, and the fixed contact 8f is engaged with the engagement piece 8f.
d and the movable contact 8e are brought into contact with each other or separated from each other. Again 1
Reference numeral 6' denotes a metal fitting, which has a hole 16'' that engages with the protrusion 17 at the center of the handle 16, and holes 16'' on both sides that engage the outer step 19 of the cylindrical protrusion 19 of the cosmetic handle 5.
It is used to engage '.

Thus, the roughly arc-shaped R-shaped parts 6, 6 provided at the center of the support parts 4, 4 of the cosmetic handle 5, which are cut and raised pieces cut and formed on the mounting bracket 1,
When the cylindrical protrusion 19 is press-fitted into the protrusion 17 of the handle 16 of the switch 8, it comes into contact with the back surface 5a of the cosmetic handle 5. That is, the portions corresponding to the upper and lower ends of the decorative handle 5 are supported by a substantially arc-shaped R portion provided at the center of the support portion 4 of the decorative handle 5 cut out from the mounting bracket 1, and the switch 8 is connected at the center. It will be engaged and held by the handle 16.

〔Effect of the invention〕

As described above, according to the present invention, the switch 8
, a mounting bracket 1 having two screw through holes 3b for fixing the switch 8 and attaching it to the embedded switch box 3, a plate portion, and the switch 8.
In the switch, the decorative handle 5 is provided with an engagement means on the back surface thereof and has a projected area larger than the projected area of the switch 8. Cut and raised pieces 4, 4 are provided which extend and form a substantially arc-shaped R portion in the center thereof, and this substantially arc-shaped R portion 6,
Since the makeup handle support structure is such that the makeup handle 6 is always in contact with the back surface of the makeup handle, even if the makeup handle is made sufficiently large and the end thereof is pressed, the cylindrical protrusion on the back surface 5a of the makeup handle 5 will not be affected. No unnatural forces act on 19.

Therefore, the makeup handle 5 is tilted,
Things like not being able to reverse smoothly,
There is no possibility that the cylindrical protrusion 19 will be damaged.

Furthermore, as shown in FIG. 2, when the mounting bracket 1 is strongly tightened to the switchbox with the screw 3a, it is generally curved, but according to the present invention, it is integral with the mounting bracket 1 and is curved at right angles to the longitudinal direction. Since the cut and raised pieces 4, 4 are formed at positions close to the respective through holes 3a, 3b, the mounting bracket 1 will not be bent even if it is strongly tightened with the screw 3a when mounting it on the switch box. Therefore, the supporting position of the decorative handle does not shift, so that stable support can be provided at all times.
