Description

[Detailed description of the invention] [Industrial field of application] The present invention allows a slide switch to be easily and reliably incorporated into the inclined surface of a case of electrical equipment, etc. so as to be dust-proof, and also allows for smooth sliding operation. It is related to the structure that allows for.

[Conventional technology]

Conventionally, when installing a slide switch on the inclined surface of an electrical equipment case, as shown in FIG. It was common to have a structure that connected to a circuit. However, with this structure, the number of parts and assembly man-hours are large, the configuration is complex, and the cost is high.In addition, in order to prevent dust from entering through the case opening 6, the flange 8 of the knob 7 or the name plate (indication board) 10 and the case 4 are Adjusting the positional relationship to prevent gaps from forming and at the same time to enable smooth sliding operation was difficult due to variations in parts and dimensions during manufacturing and assembly.

Conventionally, Japanese Utility Model Application Publication No. 48-39464 discloses a switch mounting device for mounting an operating knob 23 to a switch body 15 via a mounting plate 13 and a cushion material 18.

Further, Japanese Utility Model Publication No. 57-89233 describes a slide switch device in which a packing 4 is provided between the operating knob 2 and the device outer casing 1.

Further, Japanese Utility Model Publication No. 55-180230 discloses a dustproof plate 9 having an elastic material 11 such as a sponge attached to the back surface of a slide switch that opens and closes the switch by sliding the slide knob 2 and moving the contact piece 5. A dustproof mechanism for a slide switch is disclosed in which a slide knob 2 is fitted into the switch box 4 to close an opening 12 of the switch box 4.

[The problem that the idea attempts to solve]

The above-mentioned Utility Model Application No. 48-39464 and Utility Model Application No. 57
In all of the devices described in Japanese Patent No. 89233, the cushion material 18 or the packing 4 is fixed to the mounting plate of the switch. For this reason, there is an inconvenience that it is difficult to slide the switch smoothly. Furthermore, nothing is shown that corresponds to the nameplate in the present invention.

Further, in the device described in the above-mentioned Japanese Utility Model Application Publication No. 55-180230, the plate 10 of the slide knob 2 and the upper plate 1 of the switch box 4 are parallel, that is,
This invention relates to a structure in which a slide switch is installed on a horizontal or vertical surface. In addition, this bulletin includes
There is no description or suggestion of a structure for attaching a slide switch to an inclined surface of an electrical device.

The present invention was developed in view of the above points, and the object is to provide a structure for incorporating a slide switch into the inclined surface of an electrical equipment case, which can obtain a reliable dustproof effect and sliding effect with a simple configuration. It is.

[Means to solve the problem]

In order to achieve the above object, the slide switch built-in structure of the present invention has a structure in which a slide switch is installed on an inclined surface inclined with respect to the bottom plate of an electrical equipment case, as shown in the drawings.
In the structure in which the slide switch 1 is installed, the slide switch 1 is attached to the printed circuit board 12 parallel to the bottom plate, and the flange 8 of the knob 7 is inclined with respect to the printed circuit board 12 and parallel to the inclined surface of the electrical equipment case. and slide switch 1.
Knob 7 flange 8 and slide switch nameplate 1
The elastic material 14 is compressed and sandwiched between the elastic material 1
The knob 7 is inserted into a hole in the elastic material 14 and a hole in the name plate 10 so that the knob 7 and the name plate 4 move together with the slide operation.

[Effect]

The elastic member 14 moves together with the knob 7 and the nameplate 10 as the slide operation is performed. The nameplate 10 is constantly pressed against the inner surface of the inclined surface by the elastic material 14 and comes into close contact with the nameplate 10, so that the nameplate 10 can be slid smoothly and a reliable dustproof effect can be obtained.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. As shown in FIGS. 2 to 6, the flange of the knob is inclined with respect to the printed circuit board and parallel to the inclined surface of the electrical equipment case. Reference numeral 11 denotes a top plate that is inclined with respect to the bottom plate of the main body case of a device such as a telephone, and a knob 7 of the slide switch 1 is located in an opening 6 of this top plate 11.
is fitted onto the operating shaft 13 of the slide switch 1, which is attached to a printed circuit board 12 parallel to the bottom plate. The knob 7 is provided with a flange 8, and between the flange 8 and the inside of the opening 6 of the inclined top plate 11, a sponge-like elastic material 14 and a name plate 10 are provided.
is sandwiched between. The elastic material 14 is, for example, polyurethane foam with a specific gravity of 0.03 to 0.04 and a rectangular parallelepiped with a thickness of 4 mm.
Compress and incorporate within the range of ~3.4mm.

As shown in FIGS. 2 to 6, the collar 8 of the knob 7 is parallel to the inclined top plate 11. The thickness of the elastic material 14 must be selected so that even when the knob 7 is slid to the right (see FIG. 5), there is no gap between the lower surface of the top plate 11 and the nameplate 10. In addition, a sponge-like elastic material 1
A nameplate 10 between the switch 4 and the case allows smooth sliding operation of the switch. When assembling, the elastic material 14 and the name plate 10 are fitted to the knob 7, and the cases are assembled.

[Effect of idea]

As mentioned above, the slide switch built-in structure of the present invention can be applied to the inclined surface of an electrical equipment case, and by simply incorporating the elastic material, the elastic material, knob, and nameplate can be moved together as the slide is operated. be able to. At this time, the name plate helps in smooth sliding operation. In addition, since the slide switch can be directly attached to the printed circuit board parallel to the bottom plate of the electrical equipment case, the configuration and assembly work can be simplified, the number of parts can be reduced, and manufacturing can be done at low cost. Even if the distance between the two parts changes, a reliable dust-proofing effect can be easily obtained, and furthermore, even if there are manufacturing variations in the mutual positional relationship of the parts, it can be absorbed.
