Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a slide switch, and more particularly to a slide switch having a slide switch unit disposed close to the operating direction of the operating knob.

2. Description of the Related Art A slide switch is a type of switch installed in, for example, electronic equipment. This slide switch is configured such that a plurality of slide switch units are fixed in parallel in the vicinity of the housing of an electronic device, and the slide operation knob protrudes from an opening in the housing over its displacement range. has been done. Conventionally, in this type of slide switch, a blind plate has been attached to the space between the switch body and the casing of each slide switch unit to cover the opening from the back side of the casing. This blind plate is a plate made of vinyl chloride sheet or synthetic resin, and is attached to the slide operation knob, and is configured to be displaced in accordance with the operation of the slide operation knob. This blind plate has the functions of preventing dust etc. from entering through the opening, preventing the switch body inside the housing from being seen through the opening, and further improving the appearance of the electronic device as a whole. There is.

Problems that the invention aims to solve Recently, miniaturization and compactness have become essential for electronic devices, and accordingly, arranging switches compactly in a small space has become an important problem. There is. However, in the conventional slide switch described above, when a plurality of slide switch units are arranged close to each other, the slide switch units must be arranged at a distance that is sufficient to prevent the blind plates of each slide switch unit from coming into contact with each other. I had to. The blind plate has a length larger than the extended length of the opening because it is necessary to always cover the opening within the displacement range of the slide operation knob. Therefore, in order to arrange the slide switch units so that the blind plates of adjacent slide switch units can be smoothly operated without coming into contact with each other or getting stuck, it is necessary to adjust the distance between each slide switch unit. The problem with this is that it needs to be quite large, which hinders the miniaturization of electronic devices. In addition, conventionally, the blind plate was manufactured separately from the slide operating knob and was attached to the slide operating knob when the slide switch unit was assembled. Therefore, there were problems in that the manufacturing process became complicated and the product cost increased.

The present invention has been made in view of the above points, and an object of the present invention is to provide a slide switch that is smaller in size and lower in product cost.

Means for Solving the Problems In order to solve the above problems, the present invention includes a plurality of blind plates arranged close to each other in the direction of the slide operation of the slide operation knob and displaceable together with the slide operation knob. In a slide switch equipped with a slide switch unit, steps are provided on the front surface of one end and the back of the other end of the blind plate integrally formed at the same position of the slide operation knob, and the one end and the other end are respectively stepped. When a plurality of slide switch units are arranged close to each other in the slide operation direction, the cover plate of one slide switch unit and the cover plate of the adjacent slide switch unit are made thin according to the displacement of the cover plate in the slide operation direction. This feature is characterized in that it is configured such that they can be overlapped with each other at different levels.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a slide switch unit 1 constituting a slide switch which is an embodiment of the present invention. A slide switch 1 shown in the figure is generally composed of a switch body 2, a slide operation knob 3, a blind plate 4, and the like. This slide switch unit 1 is attached to an electronic device (not shown) and performs various electrical switching by displacing a slide operation knob 3 in the slide operation direction (direction indicated by arrow A in the figure). Generally, a plurality of slide switch units 1 are installed in an electronic device in a state in which a plurality of slide switch units 1 are placed close to each other in the slide operation direction A of the slide operation knob 3.

A switching mechanism (not shown) that actually performs electrical switching is installed inside the switch body 2, and a slide operation knob 3 that operates the switching mechanism is protruded from the front of the switch body 2. ing. The operator of the slide switch unit 1 performs the electrical switching by operating the slide operation knob 3. The slide operation knob 3 is made of synthetic resin or the like, and blind plates 4 are integrally formed on both sides of the slide operation knob 3 and extend in the slide operation direction A, and the blind plates 4 cover the slide operation knob. It is displaced according to the displacement of 3. As mentioned above, since the blindfold plate 4 is integrally formed with the slide operation knob 3, the blindfold plate is attached to the operation knob, compared to the conventional configuration in which the operation knob and the blindfold plate are separate bodies. Work can be saved, assembly work can be made easier, and parts management can be made easier.

This blindfold plate 4 has stepped portions 5 and 6 formed on extending portions 4 _-1 and 4 _-2 provided at the left and right ends of the slide operation knob 3, respectively. 6, the left and right portions of the blindfold plate 4 have staggered shapes. In other words, the blindfold board 4
has an extension 4 _-1 and a step 5 formed on the left end of the slide operation knob 3 (formed on the back surface of the extension 4 _-1 ), and an extension 4 on the right end. _-2 and a stepped portion 6 (formed on the surface of the extending portion 4 _-2 ), and each extending portion 4 _-1 , 4 _-2 and the stepped portions 5 and 6 are centered on the slide operation knob 3. It is formed so that it has a symmetrical shape in the left and right positions.
Incidentally, each of the extending portions 4 _-1 and 4 _-2 has an inclined surface 7 at its end edge.
_-1 and 7 _-2 are formed.

FIGS. 2 and 3 show a state in which a slide switch is constructed by arranging a plurality (for example, three) of the slide switch units 1 having the above configuration in close proximity to the slide operation direction A of the slide operation knob 3, The displacement state of the blindfold plate 4 when the slide operation knob 3 is operated will be described below.

Each slide switch unit 1a, 1b, 1c constituting the slide switch shown in FIG.
The slide operation knobs 3, 3b, and 3c can be switched to three positions: a left position, a center position, and a right position. Slide operation knobs 3, 3 of each slide switch unit 1a, 1b, 1c
b, 3c are attached so as to protrude from openings 9a, 9b, 9c formed in the housing 8 of the electronic device, and each blindfold plate 4a, 4b, 4c is attached to the housing 8.
Each blindfold plate 4a, 4b, arranged so as to face each opening 9a, 9b, 9c on the back side of
4c are openings 9a, 9b, 4c over the displacement range of the slide operation knobs 3a, 3b, 3c (the range shown by the arrow L in the figure in the slide switch unit 1a).
Its extension dimension is selected so as to always cover 9c from the back side of the casing 8. As a result, the openings 9a, 9
It is possible to prevent dust and the like from entering through the holes b and 9c, and to improve the appearance of the electronic device. Also,
Each slide switch unit 1a, 1 provided
b and 1c have the same configuration, so when installing each slide switch unit 1a, 1b, 1c to the housing 8, there is no need to pay attention to the installation position of each slide switch unit 1a, 1b, 1c. Therefore, the installation work can be facilitated (that is, even if the slide switch unit 1a located at the far left in the figure is placed in the center position instead of the slide switch unit 1b, there will be no inconvenience during the installation work). do not have). In FIG. 2, the slide switch unit 1a has its slide operation knob 3a in the right position, and the slide switch units 1b and 1c have their slide operation knob 3a in the right position.
b and 3c have been switched to the center position. In this state, each slide switch unit 1
The blindfold plates 4a, 4b, 4c of a, 1b, 1c are
The extending portion 4a _-1 and the stepped portion 6b, the extending portion 4b _-2 and the stepped portion 5a, the extending portion 4b _-1 and the stepped portion 6c, and the extending portion 4c _-1 and the stepped portion 5b in the A direction, respectively. is facing against.

Here, the slide operation knob 3b of the slide switch unit 1b is moved in the direction of arrow _A1 in the figure to switch to the left position. This state is shown in FIG. As the slide operation knob 3b is displaced in the _A1 direction, the blind plate 4b is also displaced in the _A1 direction. However, a stepped portion 5a is provided on the blinding plate 4a of the slide switch unit 1a, which faces the extending portion 4b _-2 of the blinding plate 4b, and the extending portion 4b _-2 of the blinding plate 4b enters into this stepped portion 5a. I will do it. Similarly, the extension portion 4 of the slide switch unit 1a comes relatively close to the blind plate 4b of the slide switch unit 1b due to the displacement of the slide operation knob 3b.
A _-1 enters the stepped portion 6b formed in the blind plate 4b of the slide switch unit 1b in opposition to this. Accordingly, the blind plates 4a and 4b of the slide switch unit 1a and the adjacent slide switch unit 1b are overlapped with each other at the stepped portions 5a and 5b formed respectively as they are displaced in the slide operation direction. Note that even if the edges of the blind plates 4, 4b touch each other slightly due to errors in the installation accuracy of the slide switch units 1a, 1b, 1c, the sloped surfaces 7a _-1 , 7b _-2
This allows the above-mentioned approach to be carried out smoothly.

Therefore, even if the blindfold plates 4a, 4b, 4c are displaced by operating the slide operation knobs 3a, 3b, 3c, adjacent blindfold plates will not come into contact with each other, and the blindfold plates 4a, 4b, 4c The extension length of each slide switch unit 1a,
1b and 1c can be arranged close to each other. In addition, each blindfold plate 4a, 4b, 4c has a slide operation knob 3.
Since it is integrally molded with parts a, 3b, and 3c, the manufacturing process can be simplified and the product cost can be reduced.

Effects of the Invention As described above, according to the present invention, even if the blindfold plates are displaced by operating the slide operation knob, the blindfold plates facing each other overlap at the step, so that they do not collide. There is no problem, and the slide switches can be disposed close to each other without being restricted by the extension length of the blind plate. Therefore, when a slide switch is disposed adjacent to an electronic device or the like to form a slide switch unit, the installation space can be reduced, and the electronic device or the like can be downsized. Furthermore, since the blind plate is integrally molded with the slide operation knob, the manufacturing process can be simplified and product costs can be reduced. Furthermore, when assembling a slide switch unit, since each of the multiple slide switches arranged has the same configuration, the assembly work is easier than the conventional work of assembling multiple slide switches with different configurations. It is possible to achieve simplification and efficiency, and in addition, it is possible to facilitate parts management.
