プッシュスイッチpush switch
 本発明は、プッシュスイッチに関する。 The present invention relates to a push switch.
 下記特許文献1には、ハウジング内に第1タクト板と第2タクト板とを配置し、キートップの押圧による第1タクト板の1段目の変形で、第1タクト板の凸部を第2タクト板に接触させ、キートップの押圧による第1タクト板の2段目の変形で、第1タクト板の凸部が第2タクト板の中央部を押込んで第2タクト板を反転させるように構成された2段動作プッシュスイッチが開示されている。 In Patent Document 1 listed below, a first tact plate and a second tact plate are arranged in a housing, and the first stage deformation of the first tact plate by pressing the key top causes the convex part of the first tact plate to become the first tact plate. When the first tact plate is deformed in the second stage by pressing the key top, the convex part of the first tact plate presses the center part of the second tact plate, and the second tact plate is reversed. A two-stage operating push switch is disclosed.

 しかしながら、特許文献1の技術は、第1タクト板の凸部が、第1タクト板の中心に設けられており、キートップの押圧時に、キートップと第2タクト板との間に挟みこまれて高荷重を受けるため、多くの操作回数により、第1タクト板の凸部が潰れてしまい、第2タクト板に対する接触不良および押圧不良が生じる虞がある。 However, in the technology of Patent Document 1, the convex portion of the first tact plate is provided at the center of the first tact plate, and when the key top is pressed, the convex portion is sandwiched between the key top and the second tact plate. Since the first tact plate is subjected to a high load, the convex portion of the first tact plate may be crushed due to a large number of operations, and there is a possibility that a contact failure and a pressing failure with respect to the second tact plate may occur.
 一実施形態に係るプッシュスイッチは、収容部を有するハウジングと、収容部の底部に設けられた第1の固定接点と、収容部内に配置され、ドーム状を有し、上方からの押圧力を受けて反転動作することにより、第1の固定接点に接触する第1の可動接点部材と、収容部内且つ第1の可動接点部材の上側に配置され、ドーム状を有し、上方からの押圧力を受けて反転動作することにより、第1の可動接点部材の頂部に接触する第2の可動接点部材と、第2の可動接点部材の頂部上に配置され、第2の可動接点部材の頂部を押圧する押圧部を有する押圧体とを備え、第2の可動接点部材は、第1の可動接点部材側に突出した突出部を有し、押圧体によって当該第2の可動接点部材の頂部が押圧されたときに、突出部によって、第1の可動接点部材の頂部を押圧し、突出部は、押圧体の押圧部よりも外側に設けられている。 A push switch according to one embodiment includes a housing having a housing, a first fixed contact provided at the bottom of the housing, and a dome-shaped housing that is placed in the housing and receives a pressing force from above. The first movable contact member contacts the first fixed contact, and the first movable contact member, which has a dome shape and is disposed in the accommodation portion and above the first movable contact member, resists pressing force from above.

 第1メタルコンタクト150は、「第1の可動接点部材」の一例である。第1メタルコンタクト150は、中央部に頂部151を有する、上方(Z軸正方向)に凸状のドーム状の部材である。第1メタルコンタクト150は、薄い金属板が用いられて形成される。本実施形態では、一例として、第1メタルコンタクト150は、3枚の薄い金属製の円盤が重ねて形成される。第1メタルコンタクト150は、ハウジング160の収容部160B内に収容され、ハウジング160の収容部160Bの底部160Cに形成されている第1周辺部160Cb(図4参照)上に載置される。第1メタルコンタクト150は、その周縁部の裏面部分において、第1周辺部160Cbに設けられている第1の周辺固定接点162に接触して、第1の周辺固定接点162に電気的に接続されている。第1メタルコンタクト150は、いわゆる「反転バネ」であり、押圧体120による押圧操作がなされたとき、頂部151が第2メタルコンタクト130によって下方へ押圧され、所定の操作荷重を超えると急激に頂部151が凹状に弾性変形(反転動作)する。これにより、第1メタルコンタクト150は、頂部151の裏側の部分で、中央固定接点161と接触し、中央固定接点161と電気的に接続される。よって、第1メタルコンタクト150は、中央固定接点161と第1の周辺固定接点162とを、当該第1メタルコンタクト150を介して、互いに導通させることができる。なお、第1メタルコンタクト150は、第2メタルコンタクト130からの押圧力から解放されたときに、弾性力によって元の凸状に復帰する。
<First metal contact 150>
The first metal contact 150 is an example of a "first movable contact member." The first metal contact 150 is a dome-shaped member that has an apex 151 in the center and is convex upward (in the positive direction of the Z-axis). The first metal contact 150 is formed using a thin metal plate. In this embodiment, as an example, the first metal contact 150 is formed by stacking three thin metal disks. The first metal contact 150 is accommodated in the accommodating portion 160B of the housing 160, and placed on a first peripheral portion 160Cb (see FIG. 4) formed at the bottom 160C of the accommodating portion 160B of the housing 160. The first metal contact 150 is electrically connected to the first peripheral fixed contact 162 provided in the first peripheral portion 160Cb by contacting the first peripheral fixed contact 162 at the back surface portion of the peripheral portion thereof. ing.

As a result, the first metal contact 150 comes into contact with the central fixed contact 161 on the back side of the top portion 151, and is electrically connected to the central fixed contact 161. Therefore, the first metal contact 150 can cause the central fixed contact 161 and the first peripheral fixed contact 162 to be electrically connected to each other via the first metal contact 150. Note that when the first metal contact 150 is released from the pressing force from the second metal contact 130, it returns to its original convex shape due to elastic force.

A circular opening 141 is formed in the center of the insulating sheet 140. That is, the opening 141 is formed at a position where the top 151 of the first metal contact 150 and the top 131 of the second metal contact 130 overlap. Thereby, the insulating sheet 140 allows the top portion 151 of the first metal contact 150 to be placed within the opening 141. That is, when the insulating sheet 140 is pressed by the pressing body 120, the back side of the top 131 of the second metal contact 130 can be brought into contact with the top 151 of the first metal contact 150 through the opening 141.

 また、一実施形態に係るプッシュスイッチ100は、押圧体120による全押し操作がなされたとき、押圧体120が、第2メタルコンタクト130の頂部131をさらに押し下げる。これにより、第2メタルコンタクト130は、頂部131の裏側の部分で、第1メタルコンタクト150の頂部151を押し下げ、第1メタルコンタクト150の頂部151を凹状に弾性変形(反転動作)させる。これにより、第1メタルコンタクト150は、頂部151の裏側の部分が、中央固定接点161と接触することで、中央固定接点161と電気的に接続される。その結果、プッシュスイッチ100は、第1メタルコンタクト150を介して、中央固定接点161と第1の周辺固定接点162とが互いに導通することで、第2のスイッチオン状態となる。この際、一実施形態に係るプッシュスイッチ100は、第1メタルコンタクト150の反転動作により、押圧体120による全押し操作に対してクリック感を呈示できる。したがって、一実施形態に係るプッシュスイッチ100は、操作者に対して、第2のスイッチオン状態に切り替わったことを触覚的に把握させることができる。 Furthermore, in the push switch 100 according to one embodiment, when the pusher 120 is fully pressed, the pusher 120 further pushes down the top 131 of the second metal contact 130 . As a result, the second metal contact 130 pushes down the top part 151 of the first metal contact 150 with the back side of the top part 131, and elastically deforms the top part 151 of the first metal contact 150 into a concave shape (inversion operation). As a result, the first metal contact 150 is electrically connected to the center fixed contact 161 by bringing the back side of the top portion 151 into contact with the center fixed contact 161 . As a result, the push switch 100 enters the second switch-on state because the center fixed contact 161 and the first peripheral fixed contact 162 are electrically connected to each other via the first metal contact 150. At this time, the push switch 100 according to the embodiment can provide a click feeling in response to a full press operation by the pressing body 120 due to the reversing operation of the first metal contact 150. Therefore, the push switch 100 according to one embodiment allows the operator to tactually sense that the switch has been switched to the second switch-on state.
 なお、一実施形態に係るプッシュスイッチ100は、押圧体120による半押し操作および全押し操作が解除されたとき、第1メタルコンタクト150が自身の弾性力によって元の凸状に復帰するとともに、第2メタルコンタクト130が自身の弾性力によって元の凸状に復帰する。その結果、プッシュスイッチ100は、スイッチオフ状態に復帰する。 In addition, in the push switch 100 according to one embodiment, when the half-press operation and the full-press operation by the pressing body 120 are released, the first metal contact 150 returns to its original convex shape by its own elastic force, and the first metal contact 150 returns to its original convex shape by its own elastic force. The two-metal contact 130 returns to its original convex shape due to its own elastic force. As a result, the push switch 100 returns to the switch-off state.

FIG. 6 is an exploded perspective view of the second metal contact 130 and the pressing body 120 included in the push switch 100 according to one embodiment, viewed from below. FIG. 7 is a perspective sectional view of the second metal contact 130 and the pressing body 120 included in the push switch 100 according to one embodiment.
 図4~図7に示すように、第2メタルコンタクト130は、中央部に頂部131を有するドーム状であり、当該頂部131上には、押圧体120が配置される。押圧体120は、底面120Aから下側(Z軸負側)に突出し、第2メタルコンタクト130の頂部131を押圧する押圧部121を有する。図6に示すように、押圧部121は、下側(Z軸負側)からの平面視において円形状を有する。押圧部121がなす円形状は、底面120Aがなす円形状よりも、半径が小さい。 As shown in FIGS. 4 to 7, the second metal contact 130 has a dome shape with a top 131 in the center, and the pressing body 120 is disposed on the top 131. The pressing body 120 has a pressing portion 121 that projects downward (Z-axis negative side) from the bottom surface 120A and presses the top portion 131 of the second metal contact 130. As shown in FIG. 6, the pressing portion 121 has a circular shape when viewed from below (Z-axis negative side). The circular shape formed by the pressing portion 121 has a smaller radius than the circular shape formed by the bottom surface 120A.
 また、図4~図7に示すように、第2メタルコンタクト130は、頂部131の裏側に、裏面130B(すなわち、第1メタルコンタクト150側の面)から、下側(Z軸負側、すなわち、第1メタルコンタクト150側)に突出した突出部134を有する。突出部134は、第1メタルコンタクト150の頂部151と対向する。第2メタルコンタクト130は、押圧体120によって頂部131が押圧されたときに、頂部131の裏側に設けられている突出部134によって、第1メタルコンタクト150の頂部151を押圧する。 Further, as shown in FIGS. 4 to 7, the second metal contact 130 is attached to the back side of the top portion 131 from the back surface 130B (that is, the surface on the first metal contact 150 side) to the lower side (Z-axis negative side, that is, , the first metal contact 150 side). The protrusion 134 faces the top 151 of the first metal contact 150 . When the top 131 of the second metal contact 130 is pressed by the pressing body 120, the projection 134 provided on the back side of the top 131 presses the top 151 of the first metal contact 150.
 ここで、突出部134は、水平方向(X軸方向およびY軸方向)において、押圧体120の押圧部121よりも外側に設けられている。すなわち、突出部134は、水平方向(X軸方向およびY軸方向)において、押圧部121の外周部がなす円よりも外側に設けられている。 Here, the protruding portion 134 is provided outside the pressing portion 121 of the pressing body 120 in the horizontal direction (X-axis direction and Y-axis direction). That is, the protruding portion 134 is provided outside the circle formed by the outer peripheral portion of the pressing portion 121 in the horizontal direction (X-axis direction and Y-axis direction).
 これにより、一実施形態に係るプッシュスイッチ100は、押圧体120の押圧部121によって、第2メタルコンタクト130の頂部131における突出部134より内側の部分を押圧することができる。このため、一実施形態に係るプッシュスイッチ100は、突出部134によって第1メタルコンタクト150の頂部151が押圧されたとき、突出部134が、押圧体120と第1メタルコンタクト150との間に挟みこまれないため、突出部134に加わる荷重を、水平方向(X軸方向およびY軸方向)における突出部134の外側方向に逃がすことができる。したがって、一実施形態に係るプッシュスイッチ100によれば、第2メタルコンタクト130の突出部134が長時間の使用により潰れてしまうことを抑制することができる。 Thereby, the push switch 100 according to one embodiment can press the portion of the top portion 131 of the second metal contact 130 inside the protrusion 134 by the pressing portion 121 of the pressing body 120. Therefore, in the push switch 100 according to one embodiment, when the top portion 151 of the first metal contact 150 is pressed by the protrusion 134, the protrusion 134 is sandwiched between the pressing body 120 and the first metal contact 150. Therefore, the load applied to the protrusion 134 can be released toward the outside of the protrusion 134 in the horizontal direction (X-axis direction and Y-axis direction). Therefore, according to the push switch 100 according to one embodiment, it is possible to prevent the protruding portion 134 of the second metal contact 130 from being crushed due to long-term use.
 また、突出部134は、下側(Z軸負側、すなわち、第1メタルコンタクト150の頂部151側)からの平面視にて、環状を有する。 Furthermore, the protrusion 134 has an annular shape when viewed from below (Z-axis negative side, that is, the top 151 side of the first metal contact 150).
 これにより、一実施形態に係るプッシュスイッチ100は、突出部134によって、第1メタルコンタクト150の頂部151を環状に均一に押圧し、当該頂部151を下方(Z軸負方向)に真っ直ぐに押し下げることができる。 As a result, the push switch 100 according to the embodiment can uniformly press the top 151 of the first metal contact 150 in an annular manner by the protrusion 134, and push the top 151 straight downward (in the negative Z-axis direction). I can do it.
 また、一実施形態に係るプッシュスイッチ100は、突出部134が環状を有することにより、突出部134によって第1メタルコンタクト150の頂部151を押圧したときに、第1メタルコンタクト150から突出部134に加わる荷重を、当該突出部134の周方向に均一に分散することができるため、第2メタルコンタクト130の突出部134が長時間の使用により潰れてしまうことを抑制することができる。 In addition, in the push switch 100 according to the embodiment, since the protrusion 134 has an annular shape, when the protrusion 134 presses the top 151 of the first metal contact 150, the push switch 100 moves from the first metal contact 150 to the protrusion 134. Since the applied load can be uniformly distributed in the circumferential direction of the protrusion 134, it is possible to prevent the protrusion 134 of the second metal contact 130 from being crushed due to long-term use.
 また、一実施形態に係るプッシュスイッチ100は、突出部134が環状を有することにより、突出部134によって第1メタルコンタクト150の頂部151の中心から離れた位置(すなわち、傾斜面上)を押圧できるため、第1メタルコンタクト150の頂部151の中心を押圧する構成と比較して、押圧体120による押圧操作の上下方向(Z軸方向)のストローク量を小さくすることができる。 Further, in the push switch 100 according to one embodiment, since the protrusion 134 has an annular shape, the protrusion 134 can press a position away from the center of the top 151 of the first metal contact 150 (i.e., on an inclined surface). Therefore, compared to a configuration in which the center of the top portion 151 of the first metal contact 150 is pressed, the stroke amount in the vertical direction (Z-axis direction) of the pressing operation by the pressing body 120 can be made smaller.
 また、第2メタルコンタクト130は、表面130A(すなわち、第1メタルコンタクト150側の面とは反対側の面)に、突出部134に沿って形成された溝部135を有する。本実施形態では、突出部134が環状であるため、溝部135も環状に形成されている。また、溝部135は、水平方向(X軸方向およびY軸方向)において、押圧体120の押圧部121よりも外側に設けられている。すなわち、溝部135は、水平方向(X軸方向およびY軸方向)において、押圧部121の外周部がなす円よりも外側に設けられている。例えば、第2メタルコンタクト130は、プレス加工によって表面130A側から金属板に対して圧力が加えられることによって、突出部134および溝部135が同時に形成される。 Further, the second metal contact 130 has a groove 135 formed along the protrusion 134 on the surface 130A (that is, the surface opposite to the surface on the first metal contact 150 side). In this embodiment, since the protrusion 134 is annular, the groove 135 is also annular. Further, the groove portion 135 is provided outside the pressing portion 121 of the pressing body 120 in the horizontal direction (X-axis direction and Y-axis direction). That is, the groove portion 135 is provided outside the circle formed by the outer peripheral portion of the pressing portion 121 in the horizontal direction (X-axis direction and Y-axis direction). For example, in the second metal contact 130, the protrusion 134 and the groove 135 are simultaneously formed by applying pressure to the metal plate from the surface 130A side by press working.
 また、一実施形態に係るプッシュスイッチ100は、第2メタルコンタクト130が溝部135を有することにより、第1メタルコンタクト150から突出部134に荷重が加わったときに、溝部135が幅方向に広がるように弾性変形することで、突出部134に加わる荷重を溝部135の幅方向に逃がして、突出部134に加わる荷重を吸収できるため、第2メタルコンタクト130の突出部134が長時間の使用により潰れてしまうことを抑制することができる。 Further, in the push switch 100 according to one embodiment, the second metal contact 130 has the groove 135, so that when a load is applied from the first metal contact 150 to the protrusion 134, the groove 135 expands in the width direction. By elastically deforming, the load applied to the protruding part 134 can be released in the width direction of the groove part 135 and the load applied to the protruding part 134 can be absorbed, so that the protruding part 134 of the second metal contact 130 can be crushed due to long-term use. It is possible to prevent this from happening.
