Description

  The present invention relates to a thin two-stage switch.

  Conventionally, as a two-stage switch, as shown in Patent Document 1, for example, a central fixed contact and a lateral fixed contact located outside the case are exposed on the bottom surface of a molded resin case (switch body). A plurality of metal plates are insert molded, a movable contact made of a metal plate is placed on the fixed contacts in the case at a predetermined distance, and the movable contact is pushed down by a key top (push button). First, the movable contact and the side fixed contact are brought into contact with each other to turn on one switch, and the movable contact is pushed down by the key top so that the movable contact and the central fixed contact are brought into contact with each other and the other switch is turned on. There is a two-stage switch that is turned on.

  However, since this two-stage switch has a structure in which a metal plate is insert-molded in a case made of molded resin, the thickness of the case increases and at the same time the outer dimensions increase, making it impossible to reduce the thickness and size. Also, when trying to electrically connect the terminal part of the metal plate protruding from the case to another flexible substrate, not only complicated work such as soldering is required, but also as a synthetic resin film constituting the flexible substrate Expensive materials that are resistant to heat must be used. For these reasons, the manufacturing cost cannot be reduced.

  On the other hand, as a two-stage switch that solves the above problem, there is a two-stage switch configured by using a flexible substrate, as shown in Patent Document 2, for example. This two-stage switch is, in turn, on a lower switch constituted by a flexible substrate, an inversion plate, an actuated object made of a molded product, an upper switch constituted by a flexible substrate, an inversion plate, A key top (push button) is placed. When the key top is pressed, the upper switch is first turned on. When the key top is further pressed, the operation type object is lowered together with the upper switch so that the lower switch is turned on. Here, the flexible substrate constituting the upper and lower switches is formed by bending a single flexible substrate.

  If a two-stage switch is configured using a flexible substrate as in this conventional example, not only can the thickness be reduced, but the output of the upper and lower switches can be easily pulled out from a desired location by the flexible substrate. Electrical connection with other flexible boards can be easily performed without using soldering or the like.

However, this two-stage switch also requires an operation type made of molded resin, and accordingly, the thickness reduction and the size reduction of the outer shape are hindered. Therefore, the demand for further thickness reduction and size reduction cannot be met, and There was a problem that the demand for further reduction in the number of parts could not be met.

As shown in these drawings, the two-stage switch 1-1 includes a first flexible board 20 provided with a first contact 21 on a mounting member 10, and a second contact 50 made of an inversion plate made of an elastic metal plate. And a second flexible substrate 70 provided with a spacer member 60 and a third contact 71 is laminated on the second contact 50, and the first switch 21 and the second contact 50 form a first switch. The second contact A and the third contact 71 constitute a second switch A2 while constituting A1. An adhesive sheet 55 is attached on the second contact 50. Each component will be described below.

  The attachment member 10 is configured by a thin plate (such as a metal plate or a molded resin plate) having rigidity. However, since the mounting member 10 is simply for supporting the first and second flexible boards 20 and 70 and the like installed on the surface, the mounting member 10 is formed of various other shapes, structures, and materials. It may be.

  The first flexible substrate 20 and the second flexible substrate 70 are formed on a single flexible synthetic resin film (for example, polyethylene terephthalate film) 23, and the two are connected by a thin strip-shaped connecting portion 25. ing.

  The first flexible substrate 20 is provided with a first contact 21 made of a circular contact pattern at a predetermined position on the surface of the synthetic resin film 23, and a circular connection pattern 27 is provided at four locations around the first contact 21. The connection patterns 27 are connected by a connection pattern 29, and circuit patterns 31 and 33 are drawn from the first contact 21 and the connection pattern 27, respectively.

  The second flexible substrate 70 is formed by forming the synthetic resin film 23 in a circular shape with an outer size smaller than the outer size of the first flexible substrate 20, and a third contact formed of a circular contact pattern at the center thereof. 71, and a circuit pattern 73 is drawn from the third contact 71, passes through the connecting portion 25 and the first flexible substrate 20, and is provided on the first flexible substrate 20 together with the circuit patterns 31 and 33. Not distributed to other electrical circuits (or terminal connections). The first and third contacts 21, 71, the connection pattern 27, the connection pattern 29, and the circuit patterns 31, 33, 73 (all of which are conductive patterns) may be formed by printing a conductive paste or may be synthesized. You may form by etching the copper foil affixed on the resin film.

  The second contact 50 is constituted by an inversion plate formed by forming an elastic metal plate into a dome shape. The outer diameter of the second contact 50 is formed such that the outer periphery just contacts the four connection patterns 27 provided on the first flexible substrate 20. The upper and lower surfaces of the second contact 50 are subjected to contact metal plating (for example, Ag plating on a Ni plating base), and both the surfaces can be used as contacts. Yes.

  The adhesive sheet 55 is a rectangular adhesive sheet, and an adhesive layer is provided on the lower surface side of a thin synthetic resin film. A second contact exposed portion 57 made of a circular through hole is provided at the center.

  The spacer member 60 has a flat plate shape, and the outer shape thereof is substantially the same as that of the second flexible substrate 70 and the second contact 50, and a third contact exposed portion 61 formed of a circular through hole is provided at the center thereof. An air conducting portion 63 is provided in which the contact exposed portion 61 and the outer periphery of the spacer member 60 are cut out in a linear shape. The diameter of the third contact exposed portion 61 is slightly larger than the diameter of the third contact 71. The spacer member 60 is constituted by a double-sided adhesive sheet having adhesive layers 65 and 65 on both upper and lower surfaces thereof, and more specifically, by providing adhesive layers 65 and 65 on upper and lower surfaces of a nonwoven fabric made of an insulating material. ing. The spacer member 60 has a thickness greater than that of the third contact 71.

  Then, in order to assemble the two-stage switch 1-1, as shown in FIG. 4, the second contact point on the first flexible substrate 20 placed on the mounting member 10 is a dome-shaped convex portion facing upward. The second contact 50 is fixed on the first flexible substrate 20 by placing the adhesive sheet 55 thereon. At this time, the outer periphery of the second contact 50 abuts on the four connection patterns 27 of the first flexible substrate 20. The dome-shaped central convex portion of the second contact 50 is exposed at the second contact exposed portion 57 of the adhesive sheet 55. On the other hand, the spacer member 60 is pasted on the surface of the second flexible substrate 70 on the side where the third contact 71 is provided so that the third contact 71 is exposed through the third contact exposed portion 61 of the spacer member 60. The air conducting portion 63 provided in the spacer member 60 is located up to the outer peripheral end surface of the second flexible substrate 70 on the side facing (away from) the connecting portion 25.

  Then, the second flexible substrate 70 is placed on the second contact 50 by folding back the connecting portion 25, so that the second flexible substrate 70 is placed on the second contact 50 by the spacer member 60 as shown in FIG. Adhere, stack and integrate. Thereby, the two-stage switch 1-1 is completed.

  As shown in FIG. 1, the two-stage switch 1-1 configured as described above has a second contact 50 (a second contact 50 of the second contact 50) made of a reversal plate on the first contact 21 of the first flexible substrate 20. The first switch A1 is configured by placing the lower surface at a predetermined distance, the second flexible board 70 is placed on the second contact 50, and the third contact 71 is the second contact 50 (second contact 50). The second switch A2 is configured by stacking via a spacer member 60 (in this embodiment, an adhesive sheet 55) so as to face each other on the upper surface).

  Next, the operation of the two-stage switch 1-1 will be described. In FIG. 1, a pressing portion 80 such as a key top is installed at the center of the upper surface of the second flexible substrate 70 (the back surface of the third contact 71 of the second flexible substrate 70). The pressing unit 80 may be a finger or the like. When the second flexible substrate 70 is pressed by the pressing portion 80, as shown in FIG. 5A, the second flexible substrate 70 provided with the third contact 71 is bent downward, so that the third contact 71 is The second contact 50 abuts, whereby the third contact 71 and the second contact 50 are electrically connected, and the second switch A2 is turned on. At this time, since the space in the third contact exposed portion 61 is electrically connected to the outside air by the air conducting portion 63 provided in the spacer member 60, the pressing operation of the second flexible substrate 70 is not hindered by the sealed air.

  When the second flexible substrate 70 is further pressed by the pressing portion 80, as shown in FIG. 5B, the second contact 50 is inverted while the second switch A2 is turned on, and a click feeling is generated. At the same time, the center of the lower surface of the second contact 50 comes into contact with the first contact 21, whereby the second contact 50 and the first contact 21 are electrically connected, and the first switch A1 is also turned on.

  On the other hand, if the pressing by the pressing portion 80 is released, first, as shown in FIG. 5 (a), the second contact 50 is automatically returned to its original shape by its own elastic automatic return force, and the first switch A1 is turned on. Then, the second flexible substrate 70 that has been bent next is automatically restored to its original shape as shown in FIG. 1 by its own elastic automatic restoring force, and the second switch A2 is turned off.

  If the two-stage switch 1-1 is configured as described above, the thin first and second flexible substrates 20 and 70 are used, and it is not necessary to insert-mold them into a molded product. Since a molded product such as an actuating type is not interposed between the second switches A2, the thickness of the two-stage switch 1-1 configured by using the flexible substrates 20 and 70 is reduced and the outer shape is reduced. You can plan.

  Further, since the flexible boards 20 and 70 are used, the outputs of the first and second switches A1 and A2 can be easily drawn out to a desired outside by the synthetic resin film constituting the flexible boards 20 and 70. Furthermore, since the output can be drawn to the outside by the flexible boards 20 and 70, the electrical connection with other flexible boards can be easily performed by using a conductive adhesive or other various mechanical connection means without using soldering or the like. You can do it.

  The first flexible substrate 20 and the second flexible substrate 70 are provided on the same synthetic resin film, and the synthetic resin film is folded back so that the third flexible substrate 20 and the second flexible substrate 70 are placed on the second contact 50 installed on the first contact 21. Since the contact point 71 is installed, it is possible to easily install the three contact points with a small number of parts.

  6 is a cross-sectional view of the two-stage switch 1-2 according to the second embodiment of the present invention, FIG. 7 is a perspective view, and FIG. 8 is an exploded perspective view. In the figure, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. As shown in FIG. 6, also in the two-stage switch 1-2, the first flexible substrate 20 provided with the first contact 21 and the second contact 50 made of a reverse plate are placed on the mounting member 10. Further, the second flexible substrate 70 provided with the spacer member 60 and the third contact 71 is laminated on the second contact 50, and the first switch 21 and the second contact 50 constitute the first switch A1. The second contact 50 and the third contact 71 constitute a second switch A2.

  In this embodiment, the part different from the first embodiment is that the adhesive sheet 55 attached on the second contact 50 in the first embodiment is omitted, and the outer shape of the second flexible substrate 70 and the spacer member 60 is used instead. The dimension is made larger than the outer dimension of the second contact 50, thereby providing the spacer member 60 with a function of attaching the second contact 50 onto the first flexible substrate 20.

  In order to assemble the two-stage switch 1-2, in FIG. 8, first, the second flexible substrate 70 having a shape larger than the outer dimension of the second contact 50 is formed on the surface on the side where the third contact 71 is provided. A spacer member 60 having substantially the same outer dimensions as the flexible substrate 70 is pasted, and then the second contact 50 is placed on the first flexible substrate 20 placed on the mounting member 10, and the connecting portion 25. Is folded and the second flexible substrate 70 is placed on the second contact 50, so that the spacer member 60 attached to the second flexible substrate 70 is bonded onto the second contact 50 as shown in FIG. 7. At the same time, the outer portion 65 extending from the outer periphery of the second contact 50 of the spacer member 60 to the top of the first flexible substrate 20 is adhered to the first flexible substrate 20. In securing the second contact 50 on the first flexible substrate 20. That is, the spacer member 60 is bonded and integrated on the first flexible substrate 20 by extending from the outer periphery of the second contact 50 to the first flexible substrate 20. At this time, the outer periphery of the second contact 50 abuts on the four connection patterns 27 of the first flexible substrate 20. Thereby, the two-stage switch 1-2 is completed.

  As shown in FIG. 6, the two-stage switch 1-2 configured as described above has a second contact 50 (second contact 50) made of an inversion plate on the first contact 21 of the first flexible substrate 20. The first switch A1 is configured by placing the lower surface of the second flexible board 70 on the second contact 50 and the third contact 71 is the second contact 50 (second contact 50). The second switch A2 is configured by stacking via a spacer member 60 so as to face each other with a predetermined distance therebetween.

  Next, the operation of the two-stage switch 1-2 will be described. First, in FIG. 6, a pressing portion 80 such as a key top is installed at the center of the upper surface of the second flexible substrate 70 (the back surface of the third contact 71 of the second flexible substrate 70). The pressing unit 80 may be a finger or the like. Then, when the second flexible substrate 70 is pressed by the pressing portion 80, the second flexible substrate 70 is bent downward, so that the third contact 71 comes into contact with the second contact 50, thereby the third contact 71 and the second contact. 50 is electrically connected, and the second switch A2 is turned on. When the second flexible board 70 is further pressed by the pressing portion 80, the second contact 50 is inverted while the second switch A2 is turned on to generate a click feeling, and at the same time, the center of the lower surface of the second contact 50 is the first. The second contact 50 and the first contact 21 are electrically connected to each other, thereby turning on the first switch A1.

  On the other hand, if the pressing by the pressing portion 80 is released, the second contact 50 automatically returns to its original shape by its own elastic automatic return force, the first switch A1 is turned off, and the second bent second The flexible substrate 70 is automatically restored to its original shape by its own elastic automatic restoring force, and the second switch A2 is turned off.

  Since the two-stage switch 1-2 is configured as described above, it has the following effects in addition to the effects of the first embodiment described above. In other words, the spacer member 60 has a function of forming the second switch A2 by stacking the second flexible substrate 70 on the second contact 50 so that the third contact 71 faces the second contact 50 at a predetermined distance. In addition, since the second contact 50 is fixed to the first flexible substrate 20 and has the function of configuring the first switch A1, the adhesive sheet 55 can be omitted as described above, and the thickness can be further reduced. The number of parts can be reduced and the assembly process can be simplified.

  By the way, both the two-stage switches 1-1 and 1-2 according to the first and second embodiments are configured such that the second switch A2 has no click feeling and the first switch A1 has a click feeling. By laminating another reverse plate, the second switch A2 can also be configured with a click sensation. The third embodiment will be described below.

  FIG. 9 is a sectional view of the two-stage switch 1-3 according to the third embodiment of the present invention, and FIG. 10 is an exploded perspective view. In both figures, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. As shown in these drawings, the two-stage switch 1-3 includes a first flexible substrate 20 provided with a first contact 21 on a mounting member 10, and an inversion plate formed thereon by an adhesive sheet 55. The second contact 50 is attached, the conductive member 90 made of an inversion plate is placed on the adhesive sheet 55, and the third contact 71 conducts the second flexible substrate 70 in which the third contact 71 is provided on the conductive member 90. The first contact 21 and the second contact 50 constitute a first switch A1 and the second contact 50, the conductive member 90 and the third contact 71 are the second. Switch A2.

  In this embodiment, the difference from the first embodiment is that the inner diameter of the second contact exposed portion 57 provided on the adhesive sheet 55 is formed larger than the inner diameter of the second contact exposed portion 57 of the first embodiment, The conductive member 90 is disposed between the adhesive sheet 55 and the second flexible substrate 70, and the spacer member 60 is omitted. Instead, the outer diameter of the second flexible substrate 70 is made larger than that of the second contact 50. The adhesive layer 75 is provided from the periphery of the third contact 71 to the outer periphery of the second flexible substrate 70.

  Here, the conductive member 90 is formed of a conductive reversal plate formed by forming an elastic metal plate in a dome shape, and the outer diameter dimension thereof is substantially the same as the outer diameter dimension of the second contact 50, and the second Similar to the contact 50, the upper and lower surfaces thereof are provided with contact metal plating (for example, Ag plating on a Ni plating base), and both the surfaces can be used as contacts. Yes.

  The reason why the inner diameter of the second contact exposed portion 57 is made larger than in the case of the first embodiment is that the lower surface of the conductive member 90 becomes the upper surface of the second contact 50 when the conductive member 90 installed thereon is inverted. This is to ensure contact.

  The adhesive layer 75 provided around the third contact 71 is formed on the second flexible substrate 70 by printing or the like so as to surround the third contact 71. The thickness of the adhesive layer 75 is the same as the thickness of the third contact 71 or thinner than the thickness of the third contact 71.

  And in order to assemble this two-stage switch 1-3, in FIG. 10, the 2nd contact 50 is mounted on the 1st flexible substrate 20 mounted on the attachment member 10, and the adhesive sheet 55 is mounted on it. The second contact 50 is fixed on the first flexible substrate 20 by pasting. At this time, the outer periphery of the second contact 50 abuts on the four connection patterns 27 of the first flexible substrate 20. Next, the conductive member 90 is placed on the adhesive sheet 55. At this time, the conductive member 90 and the second contact 50 are insulated by an adhesive sheet 55 made of an insulating film. Then, the second flexible substrate 70 is mounted on the conductive member 90 by folding the portion of the connecting portion 25 and placing the second flexible substrate 70 on the conductive member 90 as shown in FIG. , Laminated and integrated. At this time, the third contact 71 formed on the second flexible substrate 70 comes into contact with the center of the upper surface of the conductive member 90, whereby the third contact 71 and the conductive member 90 are electrically connected. At this time, the adhesive layer 75 is also bonded to the upper surface of the first flexible substrate 20 around the conductive member 90, thereby integrating the members constituting the two-stage switch 1-3. Thereby, the two-stage switch 1-3 is completed.

  As shown in FIG. 9, the two-stage switch 1-3 configured as described above has a second contact 50 (a second contact 50 of the second contact 50) formed on the first contact 21 of the first flexible substrate 20. The first switch A1 is configured by placing the lower surface at a predetermined distance, and the third contact 71 provided on the second flexible substrate 70 and the conductive member 90 electrically connected thereto are placed on the second contact 50. The second switch A2 is configured by installing the conductive member 90 on the second contact 50 (the upper surface of the second contact 50) so as to face each other with a predetermined distance.

  Next, the operation of the two-stage switch 1-3 will be described. In FIG. 9, a pressing portion 80 such as a key top is installed at the center of the upper surface of the second flexible substrate 70 (the back surface of the third contact 71 of the second flexible substrate 70). The pressing unit 80 may be a finger or the like. When the second flexible substrate 70 is pressed by the pressing portion 80, as shown in FIG. 11A, the second flexible substrate 70 provided with the third contact 71 and the conductive member 90 in contact therewith are moved downward. When the conductive member 90 moves and reverses to cause a click sensation, the lower surface of the conductive member 90 abuts against the second contact 50, whereby the third contact 71 and the second contact 50 are electrically connected, The second switch A2 is turned on.

  When the second flexible substrate 70 is further pressed by the pressing portion 80, as shown in FIG. 11B, the second contact 50 is inverted while the second switch A2 is turned on, and a click feeling is generated. At the same time, the center of the lower surface of the second contact 50 comes into contact with the first contact 21, whereby the second contact 50 and the first contact 21 are electrically connected, and the first switch A1 is also turned on.

  On the other hand, if the pressing by the pressing portion 80 is released, first, as shown in FIG. 11A, the second contact 50 is automatically returned to its original shape by its own elastic automatic return force, and the first switch A1 is turned on. Next, the conductive member 90 that has been reversed is automatically restored to its original shape as shown in FIG. 9 by its own elastic automatic restoring force, and the second switch A2 is turned off.

  Since the two-stage switch 1-3 is configured as described above, in addition to the effects of the first embodiment described above, the first switch A1 (second-stage switch) and the second switch A2 (first-stage switch) In addition, there is an effect that a click feeling can be generated in both of the switches.

  In this embodiment, the outer diameter of the conductive member 90 may be configured to be smaller than the second contact 50, or conversely, may be configured to cover the second contact 50 with a larger diameter.

  In the two-stage switch 1-3, the third contact 71 is in contact with the conductive member 90 and is always in contact with the conductive member 90. However, there may be a gap between the third contact 71 and the conductive member 90. In this case, when the back surface of the third contact 71 of the second flexible substrate 70 is pressed, the second flexible substrate 70 is first bent and the third contact 71 comes into contact with the conductive member 90 so that the two become conductive.
