Description

  The present invention relates to a push switch and an input device suitable for thinning.

  In recent years, with the reduction in thickness and weight of portable electronic devices, input devices such as keyboards used in portable electronic devices are also becoming thinner. In the keyboard input device, a plurality of push switches are arranged in a desired arrangement, and which operation key is operated is determined by a predetermined circuit process. Therefore, the push switch and the input device are desired to be thinned. A thin push switch is described in Patent Document 1, for example.

  FIG. 12 is a cross-sectional view showing a pushbutton switch 900 described in Patent Document 1. As shown in FIG. The push button switch 900 is formed in a base 901 having a fixed contact 902 and a common contact 903 disposed on the inner bottom surface thereof, and is formed in a dome shape capable of reversing the top portion 904a, and is held in a storage space 901a of the base 901. The contact spring member 904, the actuator 905 made of an elastic metal plate cantilevered by the base 901, and the dustproof sheet 906 that closes the storage space 901a of the base 901 are mainly configured.

  When the actuator 905 is pressed from above, the top 904a of the contact spring member 904 is pushed and deflected by the protrusion 905a, and when the protrusion 905a is lowered by a predetermined stroke, the top 904a is reversed, and a click feeling is generated at this time. Is done. When the top portion 904a of the contact spring member 904 is reversed, it contacts the fixed contact 902, so that the common contact 903 and the fixed contact 902 are brought into conduction, and a switch-on signal is output. When the pressing operation force on the actuator 905 is removed, the contact spring member 904 returns to its original dome shape by its own elasticity, so that the top portion 904a of the contact spring member 904 is separated from the fixed contact 902 and is switched off. .

  The push button switch 900 described in Patent Document 1 can reduce the number of parts by an amount that does not require a guide wall or lid, which is a stem holding mechanism, as compared with a push button switch that moves the stem up and down, thereby improving assembly. It is easy to promote thinning. From this point of view, it has been considered to further reduce the thickness of the actuator based on the push button switch 900, so that a flat actuator without the protrusion 905a is obtained.

  However, if the flat actuator is not provided with a protrusion, as it is pushed in, not only the apex of the contact spring member 904 but also the slope of the dome is pushed at the same time, so the feeling of pushing becomes worse. There was a problem. In addition, the end of the flat plate portion of the actuator is in contact with the base 901 or the vicinity of the end of the contact spring member 904 during pushing, and the contact spring member 904 cannot be sufficiently reversed and pushed in, resulting in poor operation feeling. There was a problem of becoming.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. For easy understanding, the dimensions of the drawings are appropriately changed.

[First Embodiment]
FIG. 1 is an exploded perspective view showing a push switch 1 according to a first embodiment of the present invention. FIG. 2 is a plan view showing the push switch 1. 3 is a cross-sectional view taken along line III-III in FIG. FIG. 4 is an explanatory diagram showing the push switch 1 in a pressing operation state in the same cross section as FIG.

  As shown in FIG. 1, the push switch 1 of the present embodiment includes a thin plate base 10, a detection unit 20, a dome-shaped spring member 40, a thin plate-shaped swing member 30, and an elastic member. A support member 50 and a flexible sheet member 60 are provided.

  The base 10 is made of a synthetic resin that is an insulating material. For the base 10, for example, a printed wiring board in which an epoxy resin is formed into a plate shape and a wiring material is embedded can be used. In FIG. 1, the wiring material is not shown. The base 10 is arranged in a plane along the XY plane so that the Z1 side in FIG. Moreover, the base 10 has the hole 10b, as shown in FIG.

  In the push switch 1 of the present embodiment, a fixed contact member 21 and a support contact member 22 made of a conductive material are provided as the detection means 20. The fixed contact member 21 and the support contact member 22 can be connected to an electric circuit via a wiring material (not shown).

  The spring member 40 is made of a metal plate having elasticity and conductivity, and as shown in FIGS. 1 and 3, a dome portion 40a having an outer shape bulging in a dome shape and a leg portion protruding from the outer periphery of the dome portion 40a. 40b. The dome portion 40a has a dome shape whose top portion swells toward the Z1 side. The spring member 40 is elastically deformed so as to give a reaction force when the dome portion 40a is pressed in the Z2 direction by a pressing operation from the Z1 direction, and is inverted so that the direction in which the apex of the dome portion 40a bulges is reversed. It is possible to operate. Moreover, it has the elasticity to return to the original bulging direction when released from this press.

  The swing member 30 is made of a metal material having relatively high rigidity such as stainless steel, and includes a thin plate-like base portion 31 and a drive portion 32. The base portion 31 is bent in the Z1-Z2 direction of FIG. 1, and the end surface on the Z2 side is a restricting portion 31a. The drive part 32 is connected to the base part 31 and extends in a flat plate shape in a direction along the upper surface of the base 10 parallel to the XY plane of FIG. 1, and an opening part 32b having a notch on the distal end part 32c side. Is provided. Further, the driving portion 32 of the swinging member 30 is provided with a pushing portion 32a that protrudes in the Y1 direction so as to face the opening portion 32b.

  The support member 50 is made of an elastic member, and has a rectangular parallelepiped shape elongated in the X1-X2 direction, as shown in FIG. The support member 50 has an adhesive material (not shown) on the Z1 side and the Z2 side, and is disposed on the upper surface side of the base 10. Further, the base 31 of the swing member 30 is adhered to and held on the upper surface of the support member 50.

  The sheet member 60 is made of a synthetic resin, which is a flexible insulating material. As shown in FIGS. 1 and 3, the sheet member 60 has a bulging portion 60 a that bulges in the Z1 direction, and an adhesive material (not shown). Accordingly, the spring member 40 is fixed to the central portion of the bulging portion 60a. The sheet member 60 includes a plurality of slits 60 b provided outward from a region in contact with the spring member 40.

  In the push switch 1 of the present embodiment, when the swinging member 30 is pressed from the Z1 direction, the drive unit 32 moves downward with the base 31 held by the support member 50 as a rotation fulcrum, The detecting means 20 detects the downward movement of the drive unit 32.

  More specifically, the detection unit 20 has a switch configuration that detects electrical continuity between the fixed contact member 21 and the support contact member 22. The drive portion 32 of the swing member 30 is provided with a pushing portion 32a for pushing the apex of the dome portion 40a of the spring member 40, and the apex of the dome portion 40a is reversed to support the fixed contact member 21 and the support member 21. Electrical connection with the contact member 22 is made. Further, when the apex of the dome portion 40a is reversed, an operation feeling in which the operation load changes sharply is obtained. In addition, as described above, the embodiment is not limited to the electrical conduction mode in which the spring member 40 is the movable contact member, and the spring member 40 moves the movable member having the movable contact to be electrically connected to the fixed contact member. An aspect may be sufficient.

  Further, the support member 50 is an elastic member, and if it is only swinging, the operation feeling becomes heavy when the support member 50 side of the swinging member 30 is pressed. A feeling of operation without any sense of incongruity can be obtained. In addition, when the support member 50 side of the swing member 30 is pressed, the restricting portion 31a of the base portion 31 abuts on the base 10 so that the pushing portion 32a can press the apex of the dome portion 40a of the spring member 40, Acts as a pivot point.

  As shown in FIG. 4, in a state where the apex of the dome portion 40a of the spring member 40 is reversed, the spring force that the spring member 40 tries to return to the original shape is stored. For this reason, the spring member 40 gives a reaction force to the downward movement of the drive unit 32, and when released from the pressing operation state, returns to the initial state shown in FIG. In these drawings, the dimensions in the Z1-Z2 direction are enlarged.

  Thus, although the downward movement of the drive unit 32 is performed by the pressing operation, when the opening 32b is not provided around the push-in portion 32a, the interference with the spring member 40 other than the push-in portion 32a. Will occur. For this reason, the slope of the dome portion 40a is also pushed at the same time, and there is a problem that the feeling of pushing becomes worse. Conventionally, if a protrusion is provided on a member for pressing the apex of the dome portion 40a, the problem of pressing the inclined surface of the dome portion 40a did not occur, but the thickness could not be reduced accordingly.

  To deal with this problem, in the push switch 1 of the present embodiment, as shown in FIG. 2, the drive unit 32 has an opening 32b at a position in the direction away from the base 31 around the push-in portion 32a in plan view. Therefore, interference with the spring member 40 can be avoided. Therefore, even the swinging member 30 having no protrusion on the pushing portion 32a can be operated without interfering with the spring member 40 to a position where the detecting means 20 detects the downward movement of the driving portion 32. The reversing operation of the spring member 40 is performed smoothly, and a good operation feeling is obtained. Moreover, since the drive part 32 does not require a protrusion, a thin switch device can be achieved.

  Furthermore, in the push switch 1 of the present embodiment, the hole 10b of the base 10 corresponds to the shape of the tip 32c so as to surround the tip 32c of the drive unit 32 in a plan view as shown in FIG. Is provided. As a result, the distal end portion 32c is prevented from interfering with the base 10 while the distal end portion 32c of the drive unit 32 moves further downward with the base portion 31 as a pivot point. Since there is no interference between the drive unit 32 and the base 10, a more stable operation feeling can be obtained. Further, the stroke can be secured even if the spring member 40 is thin.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  The push switch 1 of this embodiment includes a thin plate-like base 10 and a support member 50 disposed on the upper surface side of the base 10. In addition, a base plate 31 held by the support member 50 and a thin plate-like swinging member 30 having a flat plate-like drive unit 32 connected to the base portion 31 and extending along the upper surface of the base 10 are provided. Furthermore, a dome-shaped spring member 40 that applies a reaction force to the downward movement of the drive unit 32 and can be reversed is provided, and a detection unit 20 that detects the downward movement of the drive unit 32. And the drive part 32 has the pushing part 32a for pushing the vertex of the spring member 40, and interference with the spring member 40 other than the pushing part 32a in the position of the direction away from the base 31 around the pushing part 32a. It has the opening part 32b which can avoid.

  According to this configuration, even with the swinging member 30 having no protrusion on the pushing portion 32a of the drive unit 32, the detection unit 20 does not interfere with the spring member 40 to the position where the detection unit 20 detects the downward movement of the drive unit 32. Operation is possible. For this reason, the reversing operation of the spring member 40 is performed smoothly, and a good operation feeling can be obtained. Moreover, since the drive part 32 of the rocking | swiveling member 30 does not require a protrusion, it can be made thin.

  Moreover, in the push switch 1 of this embodiment, it is preferable that the base 10 has the hole 10b corresponding to the shape of the drive part 32. FIG.

  According to this configuration, since there is no interference between the drive unit 32 and the base 10, a more stable operation feeling can be obtained. Further, the stroke can be secured even if the spring member 40 is thin.

  Moreover, in the push switch 1 of this embodiment, it is suitable that the supporting member 50 is an elastic member.

  According to this configuration, when only the swing is performed, the operation feeling becomes heavy when the support member 50 side of the swing member 30 is pressed. However, by using the support member 50 as an elastic member, there is no sense of incongruity depending on the pressing position. A feel is obtained.

FIG. 8 is a schematic diagram illustrating the input device 100 according to the fourth embodiment. FIG. 8A is a plan view and FIG. 8B is a front view. FIG. 9 is a partial plan view seen through the operation unit 170 of the A part in FIG. 10 is a cross-sectional view taken along line XX in FIG.

  As shown in FIG. 8, the input device 100 according to the present embodiment is provided with a sheet-like operation unit 170 on one surface of a flat housing 190, and is used as an input device of a portable electronic device, for example. Is done. FIG. 8 shows an input device such as a keyboard that allows various input operations corresponding to a plurality of operation keys arranged in a plane.

  The casing 190 is made of metal or synthetic resin, and is processed into a box shape with one surface open.

  The operation unit 170 is made of a synthetic resin, which is a flexible insulating material, and is attached to one surface side of the housing 190. On the Z1 side of the operation unit 170, a rectangular frame line indicating that there are a plurality of operation keys and characters and symbols (not shown) are printed. In the input device 100 of the present embodiment, the surface of the operation unit 170 is substantially flat. In addition, the unevenness | corrugation of the grade which can be understood by touching with an operator's finger | toe may be provided.

  When the operation unit 170 is seen through and seen in a plan view, a plurality of thin plate-like swinging members 30 and a support member 150 made of an elastic member are arranged on the thin plate-like base 110, as shown in FIG. ing. Further, as shown in FIGS. 9 and 10, a dome-shaped spring member 40 and a detection unit 20 are disposed below the swing member 30. Note that the same members as those constituting the push switch 1 of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The base 110 is made of an insulating material synthetic resin. The base 110 is a flat plate having substantially the same planar dimensions as the inner bottom surface of the housing 190, and has holes 110b corresponding to the plurality of swinging members 30, as shown in FIG. For the base 110, for example, a printed wiring board in which an epoxy resin is formed in a plate shape and a wiring material is embedded can be used. 9 and 10, the wiring material is not shown.

  The support member 150 is made of an elastic member and has a rectangular parallelepiped outer shape that is elongated in the X1-X2 direction, as shown in FIG. The support member 150 has an adhesive material (not shown) on the Z1 side and the Z2 side, and is disposed on the upper surface side of the base 110. In addition, the base portions 31 of the plurality of swing members 30 are attached to and held by the upper surface of the support member 150. Although the supporting member 150 in FIG. 9 has an elongated shape that is integral with the plurality of swinging members 30, the supporting member 150 may be divided by a length corresponding to the base portion 31 of each swinging member 30.

  The sheet-like operation unit 170 is disposed so as to cover the plurality of swinging members 30. When the downward movement of the drive unit 32 is performed with respect to one swinging member 30 by the pressing operation, the drive units 32 of the adjacent swinging members 30 are held in the initial state with almost no movement. Therefore, a smooth flat surface can be obtained without dividing the operation unit 170 according to the plurality of swinging members 30.

Similar to the push switch 1 of the first embodiment, the detection means 20 constitutes a switch that detects electrical continuity between the fixed contact member 21 and the support contact member 22. In the input device 100, the detecting unit 20 detects a pressing operation on the operation unit 170 by the swinging of the swinging member 30. Each of the plurality of driving units 32 has a pushing portion 32a for pushing the apex of the spring member 40, and has an opening portion 32b at a position in the direction away from the base portion 31 around the pushing portion 32a. The fixed contact member 21 and the support contact member 22 are electrically connected to each other when the vertex of the dome portion 40a reverses with respect to the downward movement of the drive member 32 of the swing member 30. Further, when the apex of the dome portion 40a is reversed, an operation feeling in which the operation load changes sharply is obtained.

  Since the drive part 32 has the opening part 32b around the pushing part 32a, the some rocking | swiveling member 30 can avoid interference with the spring member 40 other than the pushing part 32a, respectively. Therefore, even the swinging member 30 having no protrusion on the pushing portion 32a can be operated without interfering with the spring member 40 to a position where the detecting means 20 detects the downward movement of the driving portion 32.
