Description

  The present invention relates to a pushbutton switch structure.

The push button switch used for the console or various operation devices is preferably a large button that has a click feeling and can recognize the pushing operation. For example, as shown in FIGS. 9A and 9B, a switch case 101 attached to the substrate 100, a rectangular operation case 103 connected to the switch case 101 and attached to the operation panel 102, There is one provided with a rectangular operation button 104 which is accommodated in the operation case 103 so as to be pushed. The push button switch 110 surrounds the operation button 104 with the operation case 103 along the periphery of the operation button 104, and is erected higher than the upper surface of the operation button 104 from the upper left and right sides of the operation case 103. The side wall 105 is formed. By the side wall 105 surrounding the operation button 104, it is possible to prevent the adjacent operation button 104 from being pressed by mistake.
However, since the rectangular operation button 104 is accommodated in the rectangular opening of the operation case 103, there is a possibility that a gap 106 is generated and the operation button 104 is rattled.

Further, there are cases where a plurality of such push button switches 110 are used side by side instead of being used alone. For example, as shown in FIG. 9C, there is a case in which a plurality of operation cases 103 in which operation buttons 104 are accommodated are attached to the operation panel 102 so as to be adjacent to each other (see, for example, Patent Document 1). .
However, since the plurality of push button switches 110 are arranged with the side walls 105 of the adjacent operation cases 103 in contact with each other, the intervals between the plurality of operation buttons 104 are widened depending on the thickness of the side walls 105. When the pushbutton switches 110 are arranged side by side, there is a problem that only the side wall 105 is conspicuous and the operation button 104 is difficult to push. In order to solve this problem, it is conceivable to reduce the thickness of the side wall 105 itself of the operation case 103. However, there is a possibility that the strength of the operation case 103 is reduced and the operation button 104 becomes more loose. there were.

In the present invention, not only the three push button switches 33 but also a plurality of push button switches 33 may be arranged side by side. Although not shown, the housing 30 is formed with three mounting holes 300 spaced laterally.

  As shown in FIGS. 4 and 5, when the pushbutton switches 33 are arranged side by side so that the outer wall surfaces 73 a of the side walls 73 are in contact with each other, the flange portions 72 of the operation case 7 are adjacent to each other. In addition to being in contact with each other, the front surface portion 72 a and the rear surface portion 72 b of the flange portion 72 hold the front surface 42 c and the back surface 42 d of the outer peripheral wall 42 of the operation button 4. Further, the side wall 73 of the operation case 7 is in a state in which the right side surface 42a and the left side surface 42b of the outer peripheral wall 42 of the operation button 4 are held by the inner wall surface 73b.

  According to the pushbutton switch 33 according to the embodiment described above, the side wall 73 of the operation case 7 has the outer wall surface 73a formed in a planar shape, and the inner wall surface 73b faces the operation button 4 side from the front end 73c toward the rear end 73d. The outer peripheral wall 42 of the operation button 4 has a right side surface 42a and a left side surface 42b that are opposed to the side wall 73, and is formed in a curved shape along the inner wall surface 73b. For this reason, the operation button 4 accommodated in the operation case 7 is not square-shaped, and the operation button 4 is so arranged that the right side surface 42 a and the left side surface 42 b of the outer peripheral wall 42 of the operation button 4 are fitted to the inner wall surface 73 b of the side wall 73. Since 4 is accommodated in the operation case 7, the play of the operation button 4 can be improved.

  Further, since the inner wall surface 73b of the side wall 73 and the right side surface 42a and the left side surface 42b of the operation button 4 are formed in a curved shape, a plurality of push button switches 33 are arranged side by side with the side wall 73 in contact therewith. In some cases, a design having a sense of unity with the operation button 4 can be obtained without making the side wall 73 conspicuous. Further, since the side wall 73 surrounds the operation button 4 and is formed thick on the operation button 4 side, erroneous operation of the operation button 4 is prevented. As a result, the central portion of the operation button 34 that is most pressed is firmly guarded.

According to the pushbutton switch 33 according to the embodiment described above, the front surface portion 72 a of the flange portion 72 of the operation case 7 and the front surface 42 c facing the flange portion 72 of the operation button 4 are more than the front end 73 c of the side wall 73. Each has a curved shape that curves forward. For this reason, when the plurality of push button switches 33 are arranged side by side with the side wall 73 in contact with each other, the upper surface area of the operation button 4 can be expanded forward, so that the adjacent operation button 4 is erroneously pressed. While preventing this, a finger can easily touch the operation button 4 from the front, and the operability of the operation button 4 can be improved.
Further, in order to increase the thickness of the side wall 73 in order to increase the strength of the side wall 73, it is sufficient to form the inner wall surface 73b thick without changing the lateral width of the side wall 73. When they are placed side by side in contact with each other, the space for placement does not increase.

  In the pushbutton switch 33 according to the present embodiment, the front surface portion 72a and the rear surface portion 72b of the flange portion 72 are formed in curved shapes on the outer sides, but the present invention is not limited to this, and the front surface portion of the flange portion 72 is formed. As long as 72a is formed outwardly in a curved shape, the back surface portion 72b of the flange portion 72 may be formed in a linear shape. Accordingly, if the front surface 42c of the operation button 4 is formed in a curved shape on the outside, the back surface 42d of the operation button 4 may be formed in a linear shape.

  Further, in the pushbutton switch 33 according to the present embodiment, the operation button 4 is formed so that the height dimension is lower than the side wall 73 and higher than the flange portion 72 when accommodated in the mounting frame 6 and the operation case 7. However, the present invention is not limited to this, and the operation button 4 may be formed at the same height as the side wall 73. Further, the frame body 70 of the operation case 7 includes the fitting portion 71, the flange portion 72, and the side wall 73. However, the present invention is not limited to this, and the frame body 70 surrounds the operation button 4. If it can be accommodated, at least the side wall 73 may be provided.
