Description

この発明は、取付パネルに電気機器を着脱自在に取り付ける電気機器の取付構造に関する。   The present invention relates to an electric device mounting structure in which an electric device is detachably mounted on a mounting panel.

従来、押ボタンスイッチ装置等の電気機器を取付パネル110の取付穴112に取り付ける取付構造として、図19に示すような押ボタンスイッチ装置1の取付構造が知られている(例えば、特許文献1参照)。図19に示すように、押ボタンスイッチ装置1は押ボタン11が配設されたスイッチケース12を備え、スイッチケース12の外周面には取付構造としてストッパ突起12aおよびテーパ突起12bが突設されている。そして、スイッチケース12が取付パネル110の取付穴112に挿入され取り付けられた状態で、ストッパ突起12aが取付穴112周縁部の表面に、テーパ突起12bが取付穴112周縁部の裏面に当接することでスイッチケース12が取付パネル110に固定されている。   Conventionally, as an attachment structure for attaching an electrical device such as a push button switch device to the attachment hole 112 of the attachment panel 110, an attachment structure of the push button switch device 1 as shown in FIG. 19 is known (see, for example, Patent Document 1). ). As shown in FIG. 19, the pushbutton switch device 1 includes a switch case 12 in which a pushbutton 11 is disposed, and a stopper projection 12 a and a taper projection 12 b are projected on the outer peripheral surface of the switch case 12 as an attachment structure. Yes. Then, in a state where the switch case 12 is inserted into and attached to the mounting hole 112 of the mounting panel 110, the stopper projection 12a contacts the surface of the peripheral portion of the mounting hole 112 and the taper projection 12b contacts the back surface of the peripheral portion of the mounting hole 112. The switch case 12 is fixed to the mounting panel 110.

また、図19に示すように、スイッチケース12を取付パネル110に取り付けた状態で該取付パネル110の背面側に位置するテーパ突起12bは、取付パネル110の前面側から取付穴112へスイッチケース12を挿入するのが容易となるようにスイッチケース12の下端側から上端側へ広がるようにテーパ状に形成されている。また、押ボタンスイッチ装置内の接点と外部回路とは、スイッチケース12と押圧部材13とでフレキシブル基板3を挟持した状態でねじ14により押圧部材13をスイッチケース12に固定し、前記接点とフレキシブル基板3とを圧接させることで接続されている。   In addition, as shown in FIG. 19, the taper protrusion 12 b located on the back side of the mounting panel 110 in a state in which the switch case 12 is mounted on the mounting panel 110 extends from the front side of the mounting panel 110 to the mounting hole 112. Is formed in a taper shape so as to spread from the lower end side to the upper end side of the switch case 12. Further, the contact and the external circuit in the pushbutton switch device are fixed to the switch case 12 with the screw 14 in a state where the flexible substrate 3 is sandwiched between the switch case 12 and the pressing member 13, and the contact and the flexible circuit are connected. The substrate 3 is connected by being pressed.

特開平3−145025号公報(第3頁左上欄、図2)Japanese Patent Laid-Open No. 3-1445025 (page 3, upper left column, FIG. 2)

しかし、上記した従来の押ボタンスイッチ装置1の取付構造では、スイッチケース12を取付穴112に対してほぼ垂直に挿入して当該スイッチケース12を取付パネル110に取り付けるため、次のような問題が生じるおそれがあった。すなわち、スイッチケース12のテーパ突起12bが形成された部分を、ストッパ突起12aが取付パネル110の表面に当接するまで取付穴112に対してほぼ垂直に挿入してスイッチケース12を取り付けるため、スイッチケース12の外周面に沿って押ボタンスイッチ装置1の高さ方向にテーパ突起12bを形成することとなり、テーパ突起12bの高さ方向への長さ分だけ押ボタンスイッチ装置が大型化するという問題があった。また、押ボタンスイッチをフレキシブル基板から着脱する度にねじ14の締付作業が必要となり、押しボタンスイッチ装置1の配設に手間がかかるという問題があった。   However, in the mounting structure of the conventional pushbutton switch device 1 described above, the switch case 12 is inserted almost perpendicularly to the mounting hole 112 and the switch case 12 is mounted on the mounting panel 110. There was a risk of it occurring. That is, the switch case 12 is attached by inserting the portion of the switch case 12 where the tapered protrusion 12b is formed substantially perpendicular to the mounting hole 112 until the stopper protrusion 12a contacts the surface of the mounting panel 110. The taper protrusion 12b is formed in the height direction of the pushbutton switch device 1 along the outer peripheral surface of the pushbutton switch device 1, and the pushbutton switch device is increased in size by the length in the height direction of the taper protrusion 12b. there were. Further, each time the push button switch is attached to and detached from the flexible substrate, the screw 14 needs to be tightened, and there is a problem that it takes time to arrange the push button switch device 1.

本実施形態では、電気機器として押ボタンスイッチを例に挙げて、当該押ボタンスイッチを取付パネルに着脱自在に取り付ける取付構造について説明する。まず、押ボタンスイッチ装置の構成について図1〜8を参照して説明する。即ち、本実施形態における押ボタンスイッチ装置は、樹脂製スイッチケース50を備えており、スイッチケース50は、矩形の枠体50aと、該枠体50aの上面前寄りの位置に枠体50a内を前後に仕切るべく一定形成された枠体50aの高さのほぼ半分程度の高さを有する仕切板50bと、該仕切板50bによる前端部の空間の上面を閉塞する第1の閉塞板50cと、仕切板50bによる前側を除く中央前寄りから後端にかけての空間の下面を閉塞する第2の閉塞板50dとを備えている。   In the present embodiment, a push button switch is taken as an example of an electric device, and an attachment structure for detachably attaching the push button switch to the attachment panel will be described. First, the configuration of the push button switch device will be described with reference to FIGS. That is, the push button switch device according to the present embodiment includes a resin switch case 50. The switch case 50 has a rectangular frame body 50a and a frame body 50a positioned in front of the upper surface of the frame body 50a. A partition plate 50b having a height that is approximately half the height of the frame 50a formed to be partitioned in the front-rear direction, a first closing plate 50c that closes the upper surface of the space at the front end portion of the partition plate 50b, And a second closing plate 50d that closes the lower surface of the space from the center front side to the rear end excluding the front side by the partition plate 50b.

そして、枠体50aと仕切板50bと第1の閉塞板50cとにより、枠体50a内の前端部に形成された平面視横長の長方形状を成す空間が、後述するプリント基板の配置スペース52aとして使用され、枠体50aと仕切板50bと第2の閉塞板50dとにより、枠体50a内の中央前寄りから後端にかけて形成された平面視ほぼ正方形状を成す空間が、後述する押ボタン部の上下への可動スペース52bとして使用される。   Then, a space formed in a horizontally long rectangular shape in a plan view formed at the front end portion in the frame 50a by the frame 50a, the partition plate 50b, and the first closing plate 50c serves as an arrangement space 52a for a printed circuit board to be described later. A space that is used and has a substantially square shape in plan view formed by the frame body 50a, the partition plate 50b, and the second closing plate 50d from the center front side to the rear end in the frame body 50a. Is used as a movable space 52b up and down.

まず、枠体50a内の前端部に形成された配置スペース52aには、後述する発光素子の点灯制御用の半導体集積回路54をはじめ各種の回路素子が実装されたプリント基板56が配設され、このプリント基板56のほぼ中央部にはタクトスイッチ58が実装されている。なお、プリント基板56はその裏面が第1の閉塞板50cの下面に対向して配設されており、配設状態のプリント基板56の下面側にタクトスイッチ58が位置し、この状態でタクトスイッチ58が、スイッチ固有の所定値以上の操作力によって上向きに押圧されることにより、タクトスイッチ58がオンするようになっている。   First, in the arrangement space 52a formed at the front end portion in the frame 50a, a printed circuit board 56 on which various circuit elements are mounted, including a semiconductor integrated circuit 54 for controlling the lighting of the light emitting elements described later, is disposed. A tact switch 58 is mounted almost at the center of the printed circuit board 56. The back surface of the printed circuit board 56 is disposed to face the lower surface of the first closing plate 50c, and a tact switch 58 is located on the lower surface side of the printed circuit board 56 in the disposed state. The tact switch 58 is turned on when the switch 58 is pressed upward by an operation force equal to or greater than a predetermined value unique to the switch.

また、配設状態のプリント基板56の下面後端部には、発光素子である6個(但し、個数は6個に限るものではない)の発光ダイオード(以下、LEDと称する)60が配列状態で実装され、アクリルなどの透明材料からなる断面ほぼL字状の導光部材62によりこれらのLED60の光が、可動スペース52bに配設される後述の押ボタン部72まで導光されるようになっている。このように、半導体集積回路54、タクトスイッチ58、LED60及びプリント基板等により本発明の「内部回路部」が構成されている。   In addition, at the rear end portion of the lower surface of the printed circuit board 56 in the arrangement state, six light emitting diodes (hereinafter, the number is not limited to six) which are light emitting elements (hereinafter referred to as LEDs) 60 are arranged. The light of these LEDs 60 is guided to a push button portion 72 (to be described later) disposed in the movable space 52b by a light guide member 62 having a substantially L-shaped section made of a transparent material such as acrylic. It has become. Thus, the “internal circuit portion” of the present invention is constituted by the semiconductor integrated circuit 54, the tact switch 58, the LED 60, the printed circuit board, and the like.

このとき、特に図3に示されるように、導光部材62は、可動スペース52bの左右幅よりも幅の狭い平板状基部62aと、該基部62aの前端に上向きにほぼ90゜屈曲した屈曲部62bとから成り、屈曲部62bの上端面は各LED60それぞれに近接して導光し易いように波型形状に加工されると共に、基部62aと屈曲部62bとの境界は、各部62a,62bに対してほぼ45゜の偏向用傾斜面62cが形成されている。そして、基部62aが配置スペース52a側から仕切板50bの下側を経て第2の閉塞板50dに沿って可動スペース52b内に導入され、屈曲部62bの後面が仕切板50bの前面に当接、係止されて導光部材62が枠体50a内に配設され、屈曲部62bの上端面の6個の山部分が各LED60それぞれに近接して対向配置されている。   At this time, as shown in FIG. 3 in particular, the light guide member 62 includes a flat base 62a having a width smaller than the left and right width of the movable space 52b, and a bent portion bent by approximately 90 ° upward at the front end of the base 62a. 62b, and the upper end surface of the bent portion 62b is processed into a corrugated shape so as to be easily guided near each LED 60, and the boundary between the base portion 62a and the bent portion 62b is formed on each portion 62a, 62b. On the other hand, an inclined surface 62c for deflection of approximately 45 ° is formed. And the base 62a is introduced into the movable space 52b along the second closing plate 50d through the lower side of the partition plate 50b from the arrangement space 52a side, and the rear surface of the bent portion 62b contacts the front surface of the partition plate 50b. The light guide member 62 is locked and disposed in the frame 50 a, and the six crests on the upper end surface of the bent portion 62 b are arranged close to each LED 60 and facing each other.

さらに、各LED60の発する光が、屈曲部62bの上端面の近接箇所から屈曲部62b内部に進入すると、傾斜面62cにより反射されてその方向がほぼ90゜偏向され、基部62aの面方向に各LED60の光が拡散し、その上方に配設される押ボタン部72が下方から照光されて押ボタン部72の押圧によるタクトスイッチ58のオン状態が表示、報知されるようになっている。なお、各LED60による押ボタン部72の照光効果を上げるため、導光部材62の下面に沿って白色の反射シート64が配設されている。   Further, when the light emitted from each LED 60 enters the bent portion 62b from the vicinity of the upper end surface of the bent portion 62b, the light is reflected by the inclined surface 62c and deflected by approximately 90 °, and each direction in the surface direction of the base portion 62a. The light of the LED 60 is diffused, and the push button portion 72 disposed above the LED 60 is illuminated from below, and the on state of the tact switch 58 due to the push of the push button portion 72 is displayed and notified. Note that a white reflective sheet 64 is disposed along the lower surface of the light guide member 62 in order to increase the illumination effect of the push button portion 72 by each LED 60.

ところで、プリント基板56に実装状態におけるタクトスイッチ58には、該タクトスイッチ58を下方から覆うように平面視四角形の可撓性ラバー体66が装着されており、このラバー体66の復元力とタクトスイッチ58の操作力とを合わせた下向きの力が、後述する押圧体84を介して押ボタン部72に対して上向きの付勢力として作用する。すなわち、ラバー体66とタクトスイッチ58が、押圧体84の付勢手段として機能する。よって、押ボタン部72を付勢するためのばね等の付勢手段を別途設ける必要がなく、部品点数の低減を図ることができる。   Incidentally, the tact switch 58 mounted on the printed circuit board 56 is provided with a flexible rubber body 66 having a rectangular shape in plan view so as to cover the tact switch 58 from below. A downward force combined with the operation force of the switch 58 acts as an upward biasing force on the push button portion 72 via a pressing body 84 described later. That is, the rubber body 66 and the tact switch 58 function as an urging means for the pressing body 84. Therefore, it is not necessary to separately provide a biasing means such as a spring for biasing the push button portion 72, and the number of parts can be reduced.

つぎに、枠体50a内の中央前寄りから後端にかけて形成された可動スペース52bには、ほぼ正方形の枠状を成す操作体70が上下に移動自在に配設され、この操作体70の内側には透光性を有する樹脂等から成る平面視ほぼ正方形状の押ボタン部72が着脱自在に装着されている。   Next, in the movable space 52b formed from the center front side to the rear end in the frame body 50a, an operation body 70 having a substantially square frame shape is disposed so as to be movable up and down. A push button 72 having a substantially square shape in plan view made of a resin having translucency is detachably mounted.

ここで、操作体70は、枠状部70aと、該枠状部70aの上面内周側が一様に切除されて該枠状部70aの内周に沿って形成された段差部70bとを備えており、押ボタン部72は操作体70よりも上方に突出した押圧操作部72aと、その周囲に一体形成された鍔状部72bとを備え、この鍔状部72bの上面側に形成された複数個の切欠部72cに、操作体70の枠状部70aの内周に形成された爪部70cが係合することで、押ボタン部72が操作体70に着脱自在に装着され、押ボタン部72の押圧操作部分72aを押圧操作すると、これに連動して操作体70が枠体50a内で上下に移動する。   Here, the operation body 70 includes a frame-shaped portion 70a and a stepped portion 70b formed by cutting the inner peripheral side of the upper surface of the frame-shaped portion 70a uniformly along the inner periphery of the frame-shaped portion 70a. The push button portion 72 includes a pressing operation portion 72a protruding upward from the operation body 70 and a hook-shaped portion 72b integrally formed around the pressing operation portion 72a, and is formed on the upper surface side of the hook-shaped portion 72b. By engaging a plurality of notches 72c with claw portions 70c formed on the inner periphery of the frame-like portion 70a of the operating body 70, the push button portion 72 is detachably attached to the operating body 70. When the pressing operation portion 72a of the portion 72 is pressed, the operating body 70 moves up and down in conjunction with the pressing operation portion 72a.

ところで、操作体70の枠状部70aの各辺の外側面中央には、上下のガイド溝74が形成されると共に、枠体50aの可動スペース52bの内周の前後左右に各ガイド溝74に対応してガイド条76が形成され、操作体70の枠状部70aの左辺の外側上面及び右辺の外側上面の各前後端部には、合計4個の係合凹部78が切り欠き形成され、枠体50aの可動スペース52bの内周の左右に各係合凹部78に対応して下向きの係合爪80が形成されており、操作体70の左右を片方ずつ撓ませてながら可動スペース52b内に操作体70を挿入していくと、両ガイド溝74に両ガイド条76が嵌挿しつつ各係合凹部78に各係合爪80が係合し、操作体70が上方に抜けない状態で可動スペース52b内に上動自在に配設される。   By the way, upper and lower guide grooves 74 are formed at the center of the outer surface of each side of the frame-like portion 70a of the operating body 70, and the guide grooves 74 are formed on the front and rear, right and left of the inner periphery of the movable space 52b of the frame body 50a. Correspondingly, a guide strip 76 is formed, and a total of four engagement recesses 78 are cut out at the front and rear end portions of the outer upper surface of the left side and the outer upper surface of the right side of the frame-like portion 70a of the operating body 70, Downward engaging claws 80 are formed on the left and right sides of the inner periphery of the movable space 52b of the frame 50a so as to correspond to the respective engagement recesses 78, and the left and right sides of the operating body 70 are bent one by one in the movable space 52b. When the operating body 70 is inserted into the guide groove 74, the engaging claws 80 are engaged with the engaging recesses 78 while the guide strips 76 are inserted into the guide grooves 74, and the operating body 70 is not pulled upward. It is disposed in the movable space 52b so as to be movable upward.

このとき、上記したように、後述する押圧体84を介してラバー体66の復元力とタクトスイッチ58の操作力とを合わせた下向きの力が押ボタン部72及び操作体70に上向きの付勢力として加わるため、操作体70に装着された押ボタン部72をこの付勢力に抗して下向きに押圧操作すると、操作体70が押ボタン部72の押圧に連動し、各係合爪80のうち押ボタン部72及び操作体70の押圧部位に応じた係合凹部78及びこれに係合した係合爪80を回転中心として操作体72の押圧部位が下向きに回転する。   At this time, as described above, the downward force obtained by combining the restoring force of the rubber body 66 and the operating force of the tact switch 58 is applied to the push button portion 72 and the operating body 70 via the pressing body 84 described later. Therefore, when the push button portion 72 attached to the operation body 70 is pressed downward against this biasing force, the operation body 70 is interlocked with the push of the push button portion 72 and The pressing portion of the operating body 72 rotates downward with the engaging recess 78 corresponding to the pressing portion of the push button portion 72 and the operating body 70 and the engaging claw 80 engaged therewith as the rotation center.

例えば、押ボタン部72の右前端部を押圧すると、左後側の係合凹部78とこれに係合した係合爪80が回転中心となり、押ボタン部72の左後端部を押圧すると、右前側の係合凹部78とこれに係合した係合爪80が回転中心となり、押ボタン部72の左端中央部を押圧すると、右側の両係合凹部78とこれらに係合した両係合爪80が回転中心となり、押ボタン部72の右端中央部を押圧すると、左側の両係合凹部78とこれらに係合した両係合爪80が回転中心となり、押ボタン部72を介した操作体70の押圧部位に応じて、操作体70の回転中心が切り換わる。   For example, when the right front end portion of the push button portion 72 is pressed, the engagement recess 78 on the left rear side and the engagement claw 80 engaged therewith become the rotation center, and when the left rear end portion of the push button portion 72 is pressed, When the engagement recess 78 on the right front side and the engagement claw 80 engaged therewith become the center of rotation and the center of the left end of the push button portion 72 is pressed, both engagement recesses 78 on the right side and both engagements engaged with these When the claw 80 becomes the center of rotation and the center of the right end of the push button portion 72 is pressed, the left engaging recesses 78 and the both engaging claws 80 engaged therewith become the center of rotation, and the operation via the push button portion 72 is performed. The rotation center of the operating body 70 is switched according to the pressed part of the body 70.

また、図7及び図8に示すように、平面視コ字状の金属性の押圧体84が、可動スペース52b内の操作体70の下方に配設されており、押圧体84の左右の両辺84a,84bは、図5及び図6に示すように操作体70の左、右辺下方のほぼ中央部から前端にわたって位置すると共に、押圧体84の両辺84a,84bを橋絡する前辺84cは、図3に示すように配置スペース52a内に導入され、前辺84cの前端中央に一体形成された矩形の作動片84dがラバー体66の中央の突部下面に当接している。   Further, as shown in FIGS. 7 and 8, a U-shaped metallic pressing body 84 in a plan view is disposed below the operation body 70 in the movable space 52b, and both left and right sides of the pressing body 84 are disposed. As shown in FIGS. 5 and 6, 84 a and 84 b are located from the substantially central part below the left and right sides of the operating body 70 to the front end, and the front side 84 c that bridges both sides 84 a and 84 b of the pressing body 84 is As shown in FIG. 3, a rectangular operating piece 84 d introduced into the arrangement space 52 a and integrally formed at the center of the front end of the front side 84 c is in contact with the lower surface of the protruding portion at the center of the rubber body 66.

また、押圧体84の左、右辺84a,84bの外側ほぼ中央に突出して当接片86a,86bがそれぞれ一体形成され、両当接片86a,86bの下方位置におけるスイッチケース50の枠体50a上面それぞれには、押圧体84を支える支点となる突部を成す段部88が上方に盛り上がって一体形成され、操作体70の左右両辺の下面ほぼ中央部にそれぞれ下向きに突設された当接部90が押圧体84の左、右辺84a,84bの後端部上面に当接している。   Further, the contact pieces 86a and 86b are integrally formed so as to protrude substantially to the outside of the left and right sides 84a and 84b of the pressing body 84, and the upper surface of the frame 50a of the switch case 50 at a position below the contact pieces 86a and 86b. In each of them, a stepped portion 88 that forms a protrusion serving as a fulcrum that supports the pressing body 84 is formed upward and integrally formed, and abutting portions that protrude downward at substantially the center of the lower surfaces of the left and right sides of the operating body 70. 90 is in contact with the upper surfaces of the rear end portions of the left and right sides 84a and 84b of the pressing body 84.

さらに、押圧体84は、左右の段部88に当接する両当接片86a,86bを支点とし、左右の当接部90に当接する押圧体84の左、右辺84a,84bの後端部を力点とし、ラバー体66に当接する作動片84dを作用点とする「てこ」として機能し、押ボタン部72の押圧により、その押圧部位に応じた操作体70の部位が下向きに回転すると、操作体70の両当接部90により押圧体84の左、右辺84a,84bの後端部が下向きの押し下げられ、これにより支点となる両当接片86a,86bを挟んで力点の反対側に位置する作動片84dが上向きに押し上げられてラバー体66を介してタクトスイッチ58がこれらの復元力及び操作力に抗して押圧され、タクトスイッチ58がオンするようになっている。ここでは、左右の段部88に押圧体84の両当接片86a,86bが当接して支点とするようにしているが、当接片86a,86bがなく直接押圧体84の左右の両辺84a,84bの中央部下面に当接するようにしてもよい。   Further, the pressing body 84 has the rear end portions of the left and right sides 84a and 84b of the pressing body 84 that are in contact with the left and right contact portions 90, with both contact pieces 86a and 86b contacting the left and right step portions 88 as fulcrums. It functions as a “lever” with the actuating piece 84d abutting on the rubber body 66 as the point of action, and when the part of the operating body 70 corresponding to the pressed part rotates downward by the pressing of the push button 72, the operation The rear end portions of the left and right sides 84a and 84b of the pressing body 84 are pushed downward by the both abutting portions 90 of the body 70, so that the both ends of the abutting pieces 86a and 86b serving as fulcrums are sandwiched. The actuating piece 84d is pushed upward and the tact switch 58 is pressed against the restoring force and the operating force via the rubber body 66, so that the tact switch 58 is turned on. Here, both contact pieces 86a and 86b of the pressing body 84 are in contact with the left and right step portions 88 to serve as fulcrums, but there are no contact pieces 86a and 86b, and both left and right sides 84a of the pressing body 84 are directly provided. , 84b may contact the lower surface of the central portion.

なお、押圧体84の力点の位置は、押ボタン部72及び操作体70の中心と平面視でほぼ同列上に並ぶように設定されており、これにより押ボタン部72の押圧部位がどこであっても、押圧体84の力点に加わる操作荷重をほぼ均一にしている。   In addition, the position of the force point of the pressing body 84 is set so as to be aligned substantially in the same row in plan view with the center of the push button portion 72 and the operation body 70, so that where the pressing portion of the push button portion 72 is located. Also, the operation load applied to the power point of the pressing body 84 is made substantially uniform.

そして、押圧体84の支点の位置、つまり左右の段部88が押圧体84に当接する位置を力点側または作用点側に変更すれば、押圧体84の力点に加わる操作荷重を任意に可変設定することができる。すなわち、作用点側に加わるべきタクトスイッチ58の操作力とラバー体66の復元力との合力は一定であるため、例えば支点を力点側に寄せれば、タクトスイッチ58の操作力とラバー体66の復元力との合力に打ち勝つだけの操作荷重としてより大きな荷重が必要になり、逆に支点を作用点側に寄せれば、タクトスイッチ58の操作力とラバー体66の復元力との合力に打ち勝つだけの操作荷重はより小さくて済む。   If the position of the fulcrum of the pressing body 84, that is, the position where the left and right step portions 88 abut against the pressing body 84 is changed to the power point side or the action point side, the operation load applied to the force point of the pressing body 84 can be arbitrarily variably set. can do. That is, since the resultant force of the operating force of the tact switch 58 to be applied to the action point side and the restoring force of the rubber body 66 is constant, for example, if the fulcrum is brought closer to the power point side, the operating force of the tact switch 58 and the rubber body 66 Therefore, a larger load is required as an operation load that only overcomes the resultant force of the restoring force, and conversely, if the fulcrum is moved closer to the point of action, the resultant force of the operating force of the tact switch 58 and the restoring force of the rubber body 66 The operating load that only overcomes is smaller.

ところで、特に図8に示されるように、スイッチケース50の下面側の第2の閉塞板50dには、左右の両端部から外側に張り出して前後方向の突条体92が形成され、これらの突条体92と枠体50aの左右の両辺との間に前後方向のガイド路が形成されている。   By the way, as shown in FIG. 8 in particular, the second closing plate 50d on the lower surface side of the switch case 50 is formed with protrusions 92 extending in the front-rear direction from both left and right ends, and these protrusions are formed. A guide path in the front-rear direction is formed between the strip 92 and the left and right sides of the frame 50a.

そして、図3及び図4に示すように、スイッチケース50の下面側には該下面を覆う裏面カバー94が設けられ、前記ガイド路をスライド自在に移動する内向きの鉤状係合体96が裏面カバー94の左端前後及び右端前後にそれぞれ一体形成され、これにより裏面カバー94がスイッチケース50の下面(裏面)を覆って着脱自在に装着されている。   As shown in FIGS. 3 and 4, a back cover 94 covering the lower surface is provided on the lower surface side of the switch case 50, and an inward hook-like engagement body 96 that slidably moves along the guide path is provided on the rear surface. The cover 94 is integrally formed around the left end and the right end, respectively, so that the back cover 94 is detachably mounted so as to cover the lower surface (back surface) of the switch case 50.

この裏面カバー94の後端部上面には、図7に示すように矩形凹部とその左右の線状溝から成る収容部98が形成され、中央が前側に凹状に屈曲した付勢体としての棒ばね100が、その両端が収容部98の線状溝により係止(固定)されつつ中央部が前後に移動可能に収容部98に収容されている。また、第2の閉塞板50dの後端部下面には、図8に示すように係合突起102が下向きに突出して一体形成され、この係合突起102に棒ばね100中央の屈曲部分が前側から当接し、これにより裏面カバー94が棒ばね100によってスイッチケース50に対して相対的に前方向に付勢された状態でスイッチケース50の下面に平行な前後方向にスライド自在に構成されている。   On the upper surface of the rear end portion of the back cover 94, as shown in FIG. 7, there is formed a receiving portion 98 composed of a rectangular recess and its left and right linear grooves, and a bar as a biasing body whose center is bent concavely in the front side. The spring 100 is accommodated in the accommodating portion 98 so that both ends thereof are locked (fixed) by the linear grooves of the accommodating portion 98 and the center portion is movable forward and backward. Further, as shown in FIG. 8, an engagement protrusion 102 protrudes downward and is integrally formed on the lower surface of the rear end portion of the second closing plate 50 d, and a bent portion at the center of the bar spring 100 is formed on the front side of the engagement protrusion 102. Accordingly, the back cover 94 is configured to be slidable in the front-rear direction parallel to the lower surface of the switch case 50 in a state where the back cover 94 is biased forward relative to the switch case 50 by the bar spring 100. .

なお、裏面カバー94がスイッチケース50の下面に装着された状態で、係合突起102が収容部98内に収容され、裏面カバー94がスイッチケース50に対してスライドする際に係合突起102が収容部98内を移動可能なように構成されている。このような構成とすれば、スイッチケース50の下面(第2の閉塞板50d)と、裏面カバー94の上面とを密接させることができ、押ボタンスイッチ装置の薄型化を図ることができる。   The engagement protrusion 102 is accommodated in the accommodating portion 98 in a state where the back cover 94 is mounted on the lower surface of the switch case 50, and the engagement protrusion 102 is moved when the back cover 94 slides with respect to the switch case 50. The inside of the accommodating part 98 is comprised so that a movement is possible. With such a configuration, the lower surface (second closing plate 50d) of the switch case 50 and the upper surface of the back cover 94 can be brought into close contact with each other, and the push button switch device can be thinned.

また、棒ばね100による前方への付勢力が加わっていない状態において、裏面カバー94がスイッチケース50から脱離せず、かつ、裏面カバー94を容易にスライドさせ得るように、特に後側左右の鉤状係合体96と枠体50aには凹凸の組み合わせによる係止構造が採用されている。このように本実施形態では、棒ばね100がスイッチケース50の裏面と裏面カバー94との間に設けられ裏面カバー94をスイッチケース50に対して前方向(スライド方向の一方向)に付勢している。   Further, in the state where the forward biasing force by the bar spring 100 is not applied, the rear side cover 94 is not particularly detached from the switch case 50, and the rear side cover 94 can be easily slid. The engagement body 96 and the frame body 50a employ a locking structure based on a combination of irregularities. As described above, in the present embodiment, the bar spring 100 is provided between the back surface of the switch case 50 and the back surface cover 94 and urges the back surface cover 94 forward (one direction in the sliding direction) with respect to the switch case 50. ing.

さらに、裏面カバー94の下面前端(一方の端部)には、後述する取付パネル110に形成された取付穴112の内周縁に係合する前向き横長のスイッチ取付保持用の第1フック体106が一体形成され、スイッチケース50の枠体50aの下面後端(他方の端部)には、取付穴112の内周縁に係合する後向き横長のスイッチ取付保持用の第2フック体108が一体形成されている。   Further, a first hook body 106 for holding the switch in a horizontally long forward direction that engages with an inner peripheral edge of a mounting hole 112 formed in a mounting panel 110 to be described later is provided at the front lower end (one end) of the back cover 94. A second hook body 108 for holding the switch, which is horizontally long facing backwards and engages with the inner peripheral edge of the mounting hole 112, is integrally formed at the rear end (the other end) of the lower surface of the frame body 50a of the switch case 50. Has been.

1.押ボタンスイッチ装置の取付方法
次に、組み上がった押ボタンスイッチ装置を所定の固定部材の取付位置に取り付ける方法について図9〜図11を参照して説明する。まず、図9に示すように、取付パネル110にスイッチケース50とほぼ同形状の矩形の取付穴112を穿設する。そして、図10に示すように、取付穴112の内周縁に第1フック体106を係合し、この状態でスイッチカバー50を前方へ引っ張ることで、棒ばね100の付勢力に抗しつつ裏面カバー94をスイッチケース50に対して後方へスライドさせる。
1. Next, a method for attaching the assembled push button switch device to a predetermined fixing member attachment position will be described with reference to FIGS. First, as shown in FIG. 9, a rectangular mounting hole 112 having substantially the same shape as the switch case 50 is formed in the mounting panel 110. Then, as shown in FIG. 10, the first hook body 106 is engaged with the inner peripheral edge of the mounting hole 112, and the switch cover 50 is pulled forward in this state, thereby resisting the urging force of the bar spring 100. The cover 94 is slid backward with respect to the switch case 50.

そして、両フック体106,108間の距離が縮まった状態で、第2フック体108を取付穴112の内周縁に係合させた後、スイッチカバー50の前方への引っ張りを解除すれば、棒ばね100の付勢力により裏面カバー94がスイッチケース50に対して前方へスライドしてもとの状態に戻り、図11に示すように、押ボタンスイッチ装置が取付パネル110の取付穴112にワンタッチで取り付けられる。   Then, in a state where the distance between the hook bodies 106 and 108 is reduced, the second hook body 108 is engaged with the inner peripheral edge of the mounting hole 112, and then the switch cover 50 is released from the forward pull. The back cover 94 is slid forward relative to the switch case 50 by the biasing force of the spring 100, and the push button switch device can be moved to the mounting hole 112 of the mounting panel 110 with a single touch as shown in FIG. It is attached.

一方、押ボタンスイッチ装置を取付パネル110から取り外す際には、上記した手順と逆の動作、すなわち、スイッチカバー50を前方へ引っ張ることで、棒ばね100の付勢力に抗しつつ裏面カバー94をスイッチケース50に対して後方へスライドさせる。そして、両フック体106,108間の距離が縮まった状態で、第2フック体108を取付穴112と内周縁との係合状態を解除することで、押ボタンスイッチを取付穴112から容易に、ワンタッチで取り外すことができる。   On the other hand, when the push button switch device is removed from the mounting panel 110, the reverse operation of the above procedure, that is, the switch cover 50 is pulled forward, so that the back cover 94 is resisted against the urging force of the bar spring 100. Slide backward with respect to the switch case 50. Then, in a state where the distance between the hook bodies 106 and 108 is reduced, the push-button switch can be easily removed from the mounting hole 112 by releasing the engagement state of the second hook body 108 with the mounting hole 112 and the inner peripheral edge. Can be removed with a single touch.

2.押ボタン動作
つぎに、押ボタン部72の押圧操作による押ボタンスイッチ装置の具体的動作について詳述するが、押ボタン部72の押圧に操作体70が連動するため、以下の動作等の説明では、押ボタン部72の押圧部位を操作体70の押圧部位と同一に扱って説明することとする。
2. Next, the specific operation of the push button switch device by the pressing operation of the push button portion 72 will be described in detail. However, since the operating body 70 is interlocked with the pressing of the push button portion 72, the following description of the operation and the like will be given. The pressing part of the push button portion 72 will be described in the same manner as the pressing part of the operating body 70.

上記の構成を有する押ボタンスイッチ装置が、機器起動用スイッチなどに適用され、使用者が押ボタン部72を押圧操作した場合には、操作体70がタクトスイッチ58の操作力及びラバー体66の復元力による付勢力に抗して押圧され、操作体70の両当接部90が押圧体84の左、右辺84a,84bの後端部を押し下げるため、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   When the push button switch device having the above configuration is applied to a device activation switch or the like, and the user presses the push button portion 72, the operation body 70 operates the tact switch 58 and the rubber body 66. The two abutting portions 90 of the operating body 70 are pressed against the urging force due to the restoring force and push down the rear end portions of the left and right sides 84a and 84b of the pressing body 84. The actuating piece 84d at the front end of the pressing body 84 is pushed up with the contact pieces 86a and 86b as fulcrums, whereby the tact switch 58 is pressed against the restoring force and operating force via the rubber body 66 and turned on.

このとき、タクトスイッチ58のオンにより各LED60が点灯して導光部材62により各LED60の光が押ボタン部72まで導光され、各LED60の点灯状態が所定条件の成立(スイッチ操作後、機器が所定状態になるなど)まで保持され、押ボタン部72が照光されてタクトスイッチ58がオン状態になったことが使用者に目視できるようになっている。   At this time, each LED 60 is turned on when the tact switch 58 is turned on, and the light of each LED 60 is guided to the push button portion 72 by the light guide member 62, and the lighting state of each LED 60 satisfies the predetermined condition (after the switch operation, the device Until the push button 72 is illuminated and the tact switch 58 is turned on.

いま、図2中に示す押ボタン部72の中央であるB部分が押圧されると、押ボタン部72への押圧力が操作体70のほぼ中央部に加わる。このとき、操作体70は、各係合爪80の各係合凹部78との係合箇所のいずれをも支点とすることがなく、操作体70はラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下方に平行移動し、押ボタン部72への押圧力が操作体70の中央付近に位置する両当接部90にそのまま伝わる。このとき、押圧時に両当接部90を介して操作体70が受ける反力は、押圧体84を介して受けるラバー体66の復元力とタクトスイッチ58の操作力とを合わせた力であり、これが操作荷重に相当する。   Now, when the portion B, which is the center of the push button portion 72 shown in FIG. 2, is pressed, the pressing force to the push button portion 72 is applied to the substantially central portion of the operating body 70. At this time, the operation body 70 does not use any of the engagement portions of the engagement claws 80 with the respective engagement recesses 78 as fulcrums, and the operation body 70 has the restoring force of the rubber body 66 and the tact switch 58. Parallel to the downward direction against the upward biasing force by the operating force, the pressing force to the push button portion 72 is transmitted as it is to both contact portions 90 located near the center of the operating body 70. At this time, the reaction force received by the operating body 70 via both contact portions 90 at the time of pressing is the combined force of the restoring force of the rubber body 66 received via the pressing body 84 and the operating force of the tact switch 58. This corresponds to the operation load.

その結果、操作体70の両当接部90により押圧体84の後端部が押し下げられ、上記したように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりタクトスイッチ58が押圧されてオンする。   As a result, the rear end portion of the pressing body 84 is pushed down by the both contact portions 90 of the operating body 70, and as described above, the pressing body 84 with both contact pieces 86a and 86b contacting the left and right step portions 88 as fulcrums. The actuating piece 84d at the front end is pushed up, whereby the tact switch 58 is pressed and turned on.

次に、図2中に示す押ボタン部72の中央B部分の左側のA部分が押圧されると、押ボタン部72への押圧力が操作体70の左端部寄りに加わるため、押圧体84の左辺84aを介して操作体70の左端部に加わる付勢力に抗して、操作体70の左端部が右側の両係合爪80と両係合凹部78との係合箇所P1,P2を回転中心として下向きに回転し、操作体70の左端部が下動する。   Next, when the A portion on the left side of the central B portion of the push button portion 72 shown in FIG. 2 is pressed, the pressing force applied to the push button portion 72 is applied closer to the left end portion of the operating body 70, so that the press body 84. The left end portion of the operating body 70 is engaged with the engagement portions P1 and P2 between the right engaging claws 80 and the engaging concave portions 78 against the urging force applied to the left end portion of the operating body 70 via the left side 84a. Rotating downward as the center of rotation, the left end of the operating body 70 moves downward.

そして、操作体70の左端部の下動により、操作体70の特に左側の当接部90が押圧体84の左辺84aを強く押下するが、押圧体84自体がある程度剛性を有するため、左辺84aの押下であっても押圧体84の右辺84bも同様に押下されることになる。   Then, due to the downward movement of the left end portion of the operating body 70, the contact portion 90 on the left side of the operating body 70 particularly strongly presses the left side 84a of the pressing body 84, but the pressing body 84 itself has some rigidity, so the left side 84a The right side 84b of the pressing body 84 is also pressed in the same manner.

その結果、押ボタン部72の中央B部分を押圧したのと同じように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   As a result, the actuating piece 84d at the front end of the pressing body 84 is pushed up with both abutting pieces 86a and 86b abutting on the left and right step portions 88 as fulcrums in the same manner as when the center B portion of the push button portion 72 is pressed. Thus, the tact switch 58 is pressed against the restoring force and the operating force through the rubber body 66 and is turned on.

一方、図2中に示す押ボタン72の中央B部分の右側のC部分が押圧されると、押ボタン部72への押圧力が操作体70の右端部寄りに加わるため、押圧体84の右辺84bを介して操作体70の右端部に加わる付勢力に抗して、操作体70の右端部が左側の両係合爪80と両係合凹部78との係合箇所P3,P4を回転中心として下向きに回転し、操作体70の右端部が下動する。   On the other hand, when the C portion on the right side of the central B portion of the push button 72 shown in FIG. 2 is pressed, the pressing force applied to the push button portion 72 is applied closer to the right end portion of the operating body 70, and thus the right side of the pressing body 84. 84 b against the urging force applied to the right end of the operating body 70 via the right end 84 b, the right end of the operating body 70 rotates about the engagement points P 3, P 4 between the left engaging claws 80 and the engaging recesses 78. And the right end portion of the operating body 70 moves downward.

そして、操作体70の右端部の下動により、操作体70の特に右側の当接部90が押圧体84の右辺84bを強く押下するが、押圧体84自体の剛性のため右辺84bの押下により押圧体84の左辺84aも同様に押下され、その結果、押ボタン部72の中央B部分を押圧したのと同じように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   Due to the downward movement of the right end portion of the operating body 70, the right contact portion 90 of the operating body 70 strongly presses down the right side 84b of the pressing body 84. However, due to the rigidity of the pressing body 84 itself, the right side 84b is pressed down. The left side 84a of the pressing body 84 is also pressed in the same manner. As a result, the two abutting pieces 86a and 86b that abut on the left and right step portions 88 are used as fulcrums in the same manner as when the center B portion of the push button portion 72 is pressed. The actuating piece 84d at the front end of the pressing body 84 is pushed up, whereby the tact switch 58 is pressed against the restoring force and the operating force via the rubber body 66 and turned on.

ところで、図2中に示す押ボタン部72の中央B部分の後側のE部分が押圧されると、押ボタン部72への押圧力が操作体70の後端部寄りに加わり、各係合爪80と各係合凹部78との係合箇所のうち前側、つまり上記したP2,P4を回転中心として、操作体70の後端部がラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下向きに回転し、操作体70の後端部が下動する。   By the way, when the E portion on the rear side of the center B portion of the push button portion 72 shown in FIG. 2 is pressed, the pressing force to the push button portion 72 is applied closer to the rear end portion of the operating body 70, and each engagement. The front side of the engagement portion between the claw 80 and each engagement recess 78, that is, the rear end portion of the operation body 70 with the above-described P2 and P4 as the rotation center, is due to the restoring force of the rubber body 66 and the operation force of the tact switch 58 It rotates downward against the upward biasing force, and the rear end of the operating body 70 moves downward.

そして、操作体70の後端部の下動により、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりタクトスイッチ58が押圧されてオンする。   Then, by the downward movement of the rear end portion of the operating body 70, the operating piece 84d at the front end of the pressing body 84 is pushed up with the two contact pieces 86a and 86b contacting the left and right step portions 88 as fulcrums. Is pressed and turned on.

また、図2中に示す押ボタン72の中央B部分の前側のH部分が押圧されると、押ボタン部72への押圧力が操作体70の前端部寄りに加わり、各係合爪80と各係合凹部78との係合箇所のうち前側、つまり上記したP1,P3を回転中心として、操作体70の前端部がラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下向きに回転し、操作体70の前端部が下動する。   When the front H portion of the center B portion of the push button 72 shown in FIG. 2 is pressed, the pressing force to the push button portion 72 is applied closer to the front end portion of the operating body 70, The front side of the engagement portion with each engagement recess 78, that is, the above-described P1, P3 as the rotation center, the front end portion of the operating body 70 is an upward biasing force due to the restoring force of the rubber body 66 and the operating force of the tact switch 58 The front end portion of the operation body 70 moves downward against this.

そして、操作体70の前端部の下動により、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりタクトスイッチ58が押圧されてオンする。   Then, due to the downward movement of the front end portion of the operating body 70, the operating piece 84d at the front end of the pressing body 84 is pushed up with the two contact pieces 86a and 86b contacting the left and right step portions 88 as fulcrums, thereby the tact switch 58 is Turns on when pressed.

さらに、図2中に示す押ボタン部72の左後側のD部分が押圧されると、押ボタン部72への押圧力が操作体70の左後端部寄りに加わるため、押圧体84の左辺84aを介して操作体70の左後端部に加わる付勢力に抗して、操作体70の左後端部が右前側の両係合爪80と両係合凹部78との係合箇所P2を回転中心として下向きに回転し、操作体70の左後端部が下動する。   Further, when the D portion on the left rear side of the push button portion 72 shown in FIG. 2 is pressed, the pressing force to the push button portion 72 is applied closer to the left rear end portion of the operating body 70, so The left rear end portion of the operation body 70 is engaged with the engagement claws 80 on the right front side and the engagement recesses 78 against the urging force applied to the left rear end portion of the operation body 70 via the left side 84a. Rotating downward about P2 as the rotation center, the left rear end of the operating body 70 moves downward.

また、図2中に示す押ボタン72の右後側のF部分が押圧されると、押ボタン部72への押圧力が操作体70の右後端部寄りに加わるため、押圧体84の右辺84bを介して操作体70の右後端部に加わる付勢力に抗して、操作体70の右後端部が左前側の両係合爪80と両係合凹部78との係合箇所P4を回転中心として下向きに回転し、操作体70の右後端部が下動する。   Further, when the F portion on the right rear side of the push button 72 shown in FIG. 2 is pressed, the pressing force to the push button portion 72 is applied closer to the right rear end portion of the operating body 70, and therefore the right side of the pressing body 84. The right rear end portion of the operation body 70 is engaged with the left front engagement claws 80 and the engagement recesses 78 against the urging force applied to the right rear end portion of the operation body 70 via 84b. And the right rear end of the operating body 70 moves downward.

一方、図2中に示す押ボタン72の左前側のG部分が押圧されると、押ボタン部72への押圧力が操作体70の左前端部寄りに加わるため、押圧体84の左辺84aを介して操作体70の左前端部に加わる付勢力に抗して、操作体70の左前端部が右後側の両係合爪80と両係合凹部78との係合箇所P1を回転中心として下向きに回転し、操作体70の左前端部が下動する。   On the other hand, when the G portion on the left front side of the push button 72 shown in FIG. 2 is pressed, the pressing force to the push button portion 72 is applied closer to the left front end portion of the operating body 70, so that the left side 84 a of the press body 84 is The left front end of the operating body 70 rotates about the engagement point P1 between the right rear engaging claws 80 and the both engaging recesses 78 against the urging force applied to the left front end of the operating body 70. And the left front end of the operating body 70 moves downward.

さらに、図2中に示す押ボタン72の右前側のI部分が押圧されると、押ボタン部72への押圧力が操作体70の右前端部寄りに加わるため、押圧体84の右辺84bを介して操作体70の右前端部に加わる付勢力に抗して、操作体70の右前端部が左後側の両係合爪80と両係合凹部78との係合箇所P3を回転中心として下向きに回転し、操作体70の右前端部が下動する。   Further, when the I portion on the right front side of the push button 72 shown in FIG. 2 is pressed, the pressing force to the push button portion 72 is applied closer to the right front end portion of the operating body 70, so that the right side 84 b of the pressing body 84 is The right front end portion of the operating body 70 rotates about the engagement point P3 between the left rear engaging claws 80 and both engaging recesses 78 against the urging force applied to the right front end portion of the operating body 70 via And the right front end of the operating body 70 moves downward.

そして、操作体70の左後端部、右後端部、左前端部、右前端部のいずれが下動しても、押圧体84自体がある程度剛性を有するため、図2中の押ボタン部72のA,C部分を押圧した場合と同様に、押圧体84全体が押下されることになり、その結果、押ボタン部72の中央B部分を押圧したのと同じように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の前端の作動片84dが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   Since the pressing body 84 itself has some rigidity even if any of the left rear end portion, right rear end portion, left front end portion, and right front end portion of the operating body 70 moves downward, the push button portion in FIG. As in the case where the A and C portions of 72 are pressed, the entire pressing body 84 is pressed, and as a result, the left and right step portions are the same as when the central B portion of the push button portion 72 is pressed. The actuating piece 84d at the front end of the pressing body 84 is pushed up with the two abutting pieces 86a and 86b that are in contact with the fulcrum 88 as a fulcrum, so that the tact switch 58 resists these restoring force and operating force via the rubber body 66. Turns on when pressed.

また、押ボタン部72のA部分及びC部分をそれぞれ押圧したときの操作荷重を対比すると、押圧部位であるA部分から支点P1,P2までの距離と、押圧部位であるC部分から支点P3,P4までの距離とはほぼ同じになり、しかも押ボタン72のA部分及びC部分をそれぞれ押圧したときの操作体70が受ける反力もほとんど同じであるため、押ボタン部72のA部分及びC部分をそれぞれ押圧したときの操作荷重にほとんど差はない。   Further, when the operation loads when the A portion and the C portion of the push button portion 72 are respectively pressed are compared, the distance from the A portion that is the pressing portion to the fulcrums P1 and P2, and the C portion that is the pressing portion to the fulcrum P3. The distance to P4 is almost the same, and the reaction force received by the operating body 70 when pressing the A portion and the C portion of the push button 72 is almost the same, so the A portion and the C portion of the push button portion 72. There is almost no difference in the operation load when each is pressed.

また、押ボタン部72のE部分及びH部分をそれぞれ押圧したときの操作荷重を対比すると、押圧部位であるE部分から支点P2,P4までの距離と、押圧部位であるH部分から支点P1,P3までの距離とはほぼ同じになり、しかも押ボタン部72のE部分及びH部分をそれぞれ押圧したときの操作体70が受ける反力もほとんど同じであるため、押ボタン部72のE部分及びH部分をそれぞれ押圧したときの操作荷重にほとんど差はない。   Further, when the operation loads when the E portion and the H portion of the push button portion 72 are respectively pressed are compared, the distance from the pressing portion E portion to the fulcrums P2 and P4 and the pressing portion H portion to the fulcrum P1, The distance to P3 is substantially the same, and the reaction force received by the operating body 70 when pressing the E portion and H portion of the push button portion 72 is almost the same, so the E portion and H of the push button portion 72 are the same. There is almost no difference in the operation load when each part is pressed.

また、押ボタン部72のD部分及びF部分をそれぞれ押圧したときの操作荷重を対比すると、押圧部位であるD部分から支点P2までの距離と、押圧部位であるF部分から支点P4までの距離とはほぼ同じになり、しかも押ボタン部72のD部分及びF部分をそれぞれ押圧したときの操作体70が受ける反力もほとんど同じであるため、押ボタン部72のD部分及びF部分をぞれぞれ押圧したときの操作荷重にほとんど差はない。尚、押ボタン部72のG部分及びI部分をそれぞれ押圧したときの操作荷重は、押ボタン部72のD部分及びF部分をそれぞれ押圧したときと同様の理由からほとんど同じになる。   Further, when the operation loads when pressing the D part and the F part of the push button part 72 are compared, the distance from the D part as the pressing part to the fulcrum P2 and the distance from the F part as the pressing part to the fulcrum P4. Since the reaction force received by the operating body 70 when pressing the D portion and F portion of the push button portion 72 is almost the same, the D portion and F portion of the push button portion 72 are separated. There is almost no difference in the operation load when pressed. Note that the operation loads when the G portion and the I portion of the push button portion 72 are pressed are almost the same for the same reason as when the D portion and the F portion of the push button portion 72 are pressed.

一方、押ボタン部72のB部分及びA(またはC、D,E,F,G,H,I)部分をそれぞれ押圧したときの操作荷重を対比しても、押ボタン部72のB部分及びA(またはC、D,E,F,G,H,I)部分をそれぞれ押圧したときの操作体70が受ける反力に顕著な差はないことから、押ボタン部72のB部分及びA(またはC、D,E,F,G,H,I)部分をそれぞれ押圧したときの操作荷重の差は小さく、従来のように、押ボタンの操作時における支点が1つで、その支点から遠い部位を押圧したときと近い部位を押圧したときの操作荷重の差ほど大きくなることがない。   On the other hand, even if the operation load when pressing the B portion and the A (or C, D, E, F, G, H, I) portion of the push button portion 72 is compared, Since there is no significant difference in the reaction force received by the operating body 70 when each of the A (or C, D, E, F, G, H, I) portions is pressed, the B portion of the push button portion 72 and A ( Or, the difference in operation load when pressing each of the C, D, E, F, G, H, and I) portions is small, and there is only one fulcrum when operating the push button as in the past, which is far from that fulcrum. It does not become as large as the difference in operation load when pressing a portion close to that when the portion is pressed.

よって、押ボタン部72のB部分及びA(またはC、D,E,F,G,H,I)部分をそれぞれ押圧したときの操作荷重は、使用者が違和感を覚えるほど大きくなることがなく、ほぼ同じような操作荷重になる。   Therefore, the operation load when pressing the B portion and the A (or C, D, E, F, G, H, I) portion of the push button portion 72 does not become so large that the user feels uncomfortable. The operation load is almost the same.

3.操作荷重の可変設定
また、このような操作荷重は、上記したように、押圧体84の支点の位置を適宜変更することで任意に可変設定することができる。つまり、押圧体84の作用点側に加わるべきタクトスイッチ58の操作力とラバー体66の復元力との合力は一定であることから、例えば操作荷重を現状よりも大きくしたいときには支点を力点側に寄せればよく、操作荷重を現状よりも小さくしたいときには支点を作用点側に寄せればよく、支点位置を変えることにより、非常に広い範囲(前記合力よりも大きい範囲、小さい範囲のどちらでも)で、操作荷重を可変設定できる。そして、支点の位置調整は、段部88を削ったり肉盛りするなどで対応可能である。
3. Further, the operation load can be arbitrarily set by changing the position of the fulcrum of the pressing body 84 as appropriate, as described above. That is, the resultant force of the operating force of the tact switch 58 to be applied to the action point side of the pressing body 84 and the restoring force of the rubber body 66 is constant. If you want to reduce the operating load from the current level, move the fulcrum to the point of action, and change the position of the fulcrum. The operation load can be variably set. The position of the fulcrum can be adjusted by shaving or building up the stepped portion 88.

また望ましくは、支点となる両段部88の位置を前後方向に移動自在であって、かつ、力点、作用点間の任意の位置で両段部88の位置を固定可能に、両段部88をスイッチケース50に設けるのがよい。例えば、スイッチケース50の前後方向のスライド溝を設け、このスライド溝に沿って両段部を同時にスライドできるように支持機構により支持し、スライド溝の途中数箇所に係止部を設けて、いずれかの係止部に支持機構を係止して段部の位置を固定するなどすればよい。   Desirably, both the step portions 88 can be moved in the front-rear direction, and the positions of both step portions 88 can be fixed at any position between the force point and the action point. Is preferably provided in the switch case 50. For example, a slide groove in the front-rear direction of the switch case 50 is provided, supported by a support mechanism so that both step portions can be simultaneously slid along the slide groove, and locking portions are provided at some positions in the slide groove. What is necessary is just to fix a position of a step part by locking a support mechanism to such a locking part.

以上のように、上記した実施形態によれば、以下の効果を奏することができる。すなわち、押ボタンスイッチ装置を取付パネル110に形成された取付穴112に取り付ける場合に、裏面カバー94に形成された第1フック体106を取付穴112の内周縁に引っ掛けつつ、裏面カバー94をスイッチケース50に対して棒ばね100の付勢力に抗してスライドさせ、第1フック体106とスイッチケース50に形成された第2フック体108との距離を縮めた状態で該第2フック体108を取付穴112内周縁に引っ掛かけた後、裏面カバー94のスライド状態を解除することで棒ばね100の付勢力により第1及び第2フック体106,108との距離が広がって、押ボタンスイッチ装置が第1及び第2フック体106,108により取付パネル110の取付穴112に固定される。したがって、押ボタンスイッチ装置を取付パネル110の取付穴112に容易に、しかもワンタッチで着脱自在に配設することができる。   As described above, according to the above-described embodiment, the following effects can be obtained. That is, when the pushbutton switch device is attached to the attachment hole 112 formed in the attachment panel 110, the back cover 94 is switched while the first hook body 106 formed on the back cover 94 is hooked on the inner periphery of the attachment hole 112. The second hook body 108 is slid against the urging force of the bar spring 100 with respect to the case 50 and the distance between the first hook body 106 and the second hook body 108 formed on the switch case 50 is reduced. After the hook is hooked on the inner periphery of the mounting hole 112, the sliding state of the back cover 94 is released, and the urging force of the bar spring 100 increases the distance between the first and second hook bodies 106 and 108, and the push button The switch device is fixed to the mounting hole 112 of the mounting panel 110 by the first and second hook bodies 106 and 108. Therefore, the push button switch device can be easily and detachably disposed in the mounting hole 112 of the mounting panel 110 with one touch.

また、押ボタンスイッチ装置を取付穴112に取り付ける際に、取付穴112に対してほぼ垂直方向から押ボタンスイッチ装置を挿入する従来の構成と異なり、取付穴112に対してほぼ水平方向から第1フック体106を引っ掛けた後、第2フック体108を引っ掛けることで当該押ボタンスイッチ装置を取付孔112に取り付けることができるため、第1及び第2フック体106,108を形成するために押ボタンスイッチ装置を高さ方向に大型化する必要がなく当該押ボタンスイッチ装置の薄型化を図ることができる。   Further, when the push button switch device is attached to the attachment hole 112, unlike the conventional configuration in which the push button switch device is inserted from the substantially vertical direction with respect to the attachment hole 112, the first direction from the substantially horizontal direction to the attachment hole 112 is Since the push button switch device can be attached to the attachment hole 112 by hooking the second hook body 108 after the hook body 106 is hooked, the push button is formed to form the first and second hook bodies 106, 108. There is no need to increase the size of the switch device in the height direction, and the push button switch device can be made thinner.

また、棒ばね100によって裏面カバー94をスイッチケース50に対して相対的に付勢するため、実用的な構成で確実に裏面カバー94を付勢できる。また、棒状の棒ばね100を採用することにより、該棒ばね100を収容部98内に配設することが可能となり、スイッチケース50の下面(第2の閉塞板50d)と、裏面カバー94の上面とを密接させることができるため、押ボタンスイッチ装置の薄型化を図ることができる。   Further, since the back cover 94 is biased relatively to the switch case 50 by the bar spring 100, the back cover 94 can be reliably biased with a practical configuration. Further, by adopting the bar-shaped bar spring 100, the bar spring 100 can be disposed in the accommodating portion 98, and the lower surface (second closing plate 50d) of the switch case 50 and the back cover 94 are provided. Since the upper surface can be brought into close contact with the upper surface, the push button switch device can be made thinner.

また、押ボタン部72の押圧部位に応じて操作体70の回転中心となる係合箇所の位置を切り換えることができるため、押ボタン部72の中央以外の端部や隅部を押圧した場合であっても、押圧時の操作荷重を、押ボタン部72の中央を押圧したのとほぼ同じにすることができ、押ボタン部72の押圧部位に関係なく操作荷重をほぼ均一にすることができる。   In addition, since the position of the engaging portion serving as the rotation center of the operating body 70 can be switched according to the pressed portion of the push button portion 72, when the end or corner other than the center of the push button portion 72 is pressed. Even if it exists, the operation load at the time of a press can be made substantially the same as having pressed the center of the pushbutton part 72, and the operation load can be made substantially uniform irrespective of the press part of the pushbutton part 72. .

また、タクトスイッチ58の操作力とラバー体66の復元力との合力を、押圧体84を介して操作体70の付勢力としているため、操作体70の付勢のためにばね等の付勢手段を専用に設ける必要がなく、部品点数の低減を図ることができて装置を安価に構成することが可能になる。   In addition, since the resultant force of the operating force of the tact switch 58 and the restoring force of the rubber body 66 is used as the biasing force of the operating body 70 via the pressing body 84, an urging force such as a spring is used to bias the operating body 70. There is no need to provide a dedicated means, the number of parts can be reduced, and the apparatus can be configured at low cost.

さらに、押圧体84の支点の位置を適宜調整することで、スイッチ操作荷重を可変設定することができ、使用者の好みや押ボタンスイッチ装置の使用状況に応じて操作荷重の可変設定を容易に行うことが可能になる。   Furthermore, by appropriately adjusting the position of the fulcrum of the pressing body 84, the switch operation load can be variably set, and the operation load can be easily set according to the user's preference and the use situation of the push button switch device. It becomes possible to do.

また、押ボタン部72を押圧し続けたときに、押圧体84前端の作動片84dがタクトスイッチ58に当接しつつ、操作体70を介して押圧体84の左、右辺84a,84bの後端に継続的に強い荷重がかかり続ける状況になることがあるが、例えば押圧体を矩形枠状とした場合であって、押ボタン部を押圧し続けたときに、矩形枠状の押圧体の両端部分が内蔵スイッチなどに当接してそれ以上の押下が阻止されつつ、矩形枠状の押圧体の中央部に継続的に強い荷重がかかり続ける状況になる構成、つまり押圧体の両端部分が支持された状態で押圧体の中央部に荷重がかかる、いわゆる両持ち状態の押ボタンスイッチ装置と比較して、上記した実施形態における押圧体84は、段部88で支持され押圧体84の後端(左右辺84a,84bの後端)に荷重がかかる、いわゆる片持ち状態であり、押圧体84全体に及ぶ負荷は大幅に軽減される。その結果、押圧体84の長寿命化を図ることができ、スイッチ装置全体としての長寿命化が望める。   Further, when the push button 72 is continuously pressed, the operating piece 84d at the front end of the pressing body 84 is in contact with the tact switch 58, and the rear ends of the left and right sides 84a and 84b of the pressing body 84 via the operating body 70. However, when the pressing body has a rectangular frame shape, for example, when the push button is kept pressed, both ends of the rectangular frame-shaped pressing body The structure is in a situation where a strong load is continuously applied to the central part of the rectangular frame-shaped pressing body while the part abuts against the built-in switch and the like is prevented from being pressed further, that is, both end portions of the pressing body are supported. Compared with a so-called both-end-supported pushbutton switch device in which a load is applied to the center of the pressing body in a state where the pressing body is in a state of being pressed, the pressing body 84 in the above-described embodiment is supported by the step portion 88 and the rear end of the pressing body 84 ( Of left and right sides 84a, 84b Load is applied to the end), a so-called cantilever state, the load-wide pressing body 84 is greatly reduced. As a result, the lifetime of the pressing body 84 can be increased, and the lifetime of the entire switch device can be increased.

さらに、各LED60をタクトスイッチ58と同じプリント基板56に実装し、導光部材62により各LED60の光を押ボタン部72まで導光するようにしたため、各LED60をタクトスイッチ58と別の回路基板に実装して押ボタン部72の下方に配置したり、押ボタン部72の下方以外でタクトスイッチ58とは異なる位置に配置する場合に比べ、装置の大型化を招くこともなく、より薄型の押ボタンスイッチ装置を得ることができる。   Furthermore, each LED 60 is mounted on the same printed circuit board 56 as the tact switch 58, and the light of each LED 60 is guided to the push button portion 72 by the light guide member 62. Therefore, each LED 60 is separated from the tact switch 58 by a circuit board. Compared with the case where it is mounted and disposed below the push button portion 72 or disposed at a position different from the tact switch 58 other than below the push button portion 72, the apparatus is not increased in size and is thinner. A push button switch device can be obtained.

<Second Embodiment>
Next, a second embodiment of the present invention will be described with reference to FIGS. However, FIG. 12 is an external perspective view seen from obliquely below, FIG. 13 is an exploded perspective view seen from obliquely above, FIG. 14 is an exploded perspective view seen from obliquely below, and FIGS. It is explanatory drawing of the attachment operation | movement in a different state.

本実施形態が上記第1実施形態と大きく異なる点は、図12に示すように後述する接続端子57の先端部がスイッチケース50に形成された露出孔59から露出するように構成されている点と、図13及び図15に示すように棒ばね100aの両端がスイッチケース50に固定され該棒ばね100aの中央部によって裏面カバー94に形成された係合突起99が付勢されている点である。その他の構成及び動作は上記第1実施形態とほぼ同一であるため、上記第1実施形態と同一な構成については相当符号を付してその構成および動作の説明を省略する。以下、上記第1実施形態と異なる点を中心に第2実施形態について詳細に説明する。   The present embodiment is significantly different from the first embodiment in that the tip of a connection terminal 57 described later is exposed from an exposure hole 59 formed in the switch case 50 as shown in FIG. 13 and 15, both ends of the bar spring 100a are fixed to the switch case 50, and the engagement protrusion 99 formed on the back cover 94 is urged by the central portion of the bar spring 100a. is there. Since other configurations and operations are substantially the same as those of the first embodiment, the same configurations as those of the first embodiment are denoted by the same reference numerals, and descriptions of the configurations and operations are omitted. Hereinafter, the second embodiment will be described in detail with a focus on differences from the first embodiment.

図13及び図14に示すように、本実施形態では、タクトスイッチ58等が実装されたプリント基板56の上面前端部に、導電板を片持ち状にその一端の固着部57aが該プリント基板56に固着されて他端にばね性が付与されて、下方に向って付勢力を有するように接続端子(本発明の「接続部材」に相当)57が設けられている。そして、図12及び図14に示すように、スイッチケース50の下面前方側には露出孔59が形成され、プリント基板56がスイッチケース50内に配設された状態で該プリント基板56に設けられた配線パターンに接続された接続端子57の先端部が下方に向って付勢力を有しつつスイッチケース50から露出するように構成されている。なお、露出孔59の後方側には支持部50c1が突設されており、プリント基板56が配置スペース52aに配設された状態で、支持部50c1とプリント基板56とで接続端子57の固着部57aの前よりの部分を挟持して接続端子57を支持するように構成されている。   As shown in FIGS. 13 and 14, in this embodiment, a conductive plate is cantilevered at the front end portion of the upper surface of the printed board 56 on which the tact switch 58 and the like are mounted, and a fixing portion 57 a at one end of the printed board 56 The connecting terminal (corresponding to the “connecting member” of the present invention) 57 is provided so that the other end is provided with springiness and has an urging force downward. As shown in FIGS. 12 and 14, an exposure hole 59 is formed on the front side of the lower surface of the switch case 50, and the printed circuit board 56 is provided in the printed circuit board 56 in a state of being disposed in the switch case 50. The tip of the connection terminal 57 connected to the wiring pattern is configured to be exposed from the switch case 50 while having an urging force downward. A support portion 50c1 protrudes from the rear side of the exposure hole 59. With the printed circuit board 56 disposed in the arrangement space 52a, the fixing portion of the connection terminal 57 between the support portion 50c1 and the printed circuit board 56. The connection terminal 57 is supported by sandwiching a portion from the front of 57a.

また、取付パネル110の取付穴112の周縁部には配線パターン部(図示省略)が設けられ、押ボタンスイッチ装置の取付穴112への取付時に、接続端子57が配線パターン部に接触してプリント基板56が該配線パターン部に電気的に接続されるように構成されている。このとき、接続端子57の先端部は下方に向って、すなわち取付パネル110の方向に向って付勢力を有しているため、押ボタンスイッチ装置が取付穴112に取り付けられた状態で接続端子57の先端部が取付穴112の周縁部に設けられた配線パターン部に圧接されることとなる。   In addition, a wiring pattern portion (not shown) is provided at the peripheral portion of the mounting hole 112 of the mounting panel 110, and when the push button switch device is mounted to the mounting hole 112, the connection terminal 57 contacts the wiring pattern portion and prints. The substrate 56 is configured to be electrically connected to the wiring pattern portion. At this time, the distal end portion of the connection terminal 57 has a biasing force toward the lower side, that is, toward the mounting panel 110, so that the connection terminal 57 is attached in a state where the push button switch device is mounted in the mounting hole 112. The tip end of the contact hole is brought into pressure contact with the wiring pattern provided at the peripheral edge of the mounting hole 112.

ところで、本実施形態では上記した第1実施形態と同様に、裏面カバー94がスイッチケース50の下面(裏面)を覆って着脱自在に装着されている。そして、図14に示すように、この第2の閉塞板50d(スイッチケース50)の後端部下面には、略T字状の凹部とその左右に突設された係止部103aから成る収容部103が形成され、棒ばね100aが、その両端が係止部103aにより係止(固定)されつつ中央部が前後に移動可能に収容部103に収容されている。また、裏面カバー94の後端部上面には、図13に示すように係合突起99が上向きに突出して一体形成され、この係合突起99に棒ばね100aの中央が後側から当接し、これにより裏面カバー94が棒ばね100aによってスイッチケース50に対して相対的に前方向に付勢された状態で、スイッチケース50の下面に平行な前後方向にスライド自在に構成されている。   By the way, in this embodiment, the back surface cover 94 covers the lower surface (back surface) of the switch case 50 and is detachably mounted, as in the first embodiment. As shown in FIG. 14, the rear surface of the rear end portion of the second closing plate 50 d (switch case 50) includes a substantially T-shaped concave portion and a locking portion 103 a protruding from the left and right. A portion 103 is formed, and the bar spring 100a is housed in the housing portion 103 so that both ends thereof are locked (fixed) by the locking portions 103a and the center portion is movable back and forth. Further, as shown in FIG. 13, an engagement protrusion 99 protrudes upward and is integrally formed on the upper surface of the rear end portion of the back cover 94, and the center of the bar spring 100 a comes into contact with the engagement protrusion 99 from the rear side, Thus, the back cover 94 is configured to be slidable in the front-rear direction parallel to the lower surface of the switch case 50 in a state where the back cover 94 is urged forward relative to the switch case 50 by the bar spring 100a.

なお、裏面カバー94がスイッチケース50の下面に装着された状態で、係合突起99が収容部103内に収容され、裏面カバー94がスイッチケース50に対してスライドする際に係合突起99が収容部103内(特に中央部分)を移動可能なように構成されている。このような構成とすれば、スイッチケース50の下面(第2の閉塞板50d)と、裏面カバー94の上面とを密接させることができ、押ボタンスイッチ装置の薄型化を図ることができる。   The engagement protrusion 99 is accommodated in the accommodating portion 103 in a state where the back cover 94 is mounted on the lower surface of the switch case 50, and the engagement protrusion 99 is moved when the back cover 94 slides with respect to the switch case 50. The inside of the accommodating part 103 (especially center part) is comprised so that a movement is possible. With such a configuration, the lower surface (second closing plate 50d) of the switch case 50 and the upper surface of the back cover 94 can be brought into close contact with each other, and the push button switch device can be thinned.

また、上記した第1実施形態と同様に、裏面カバー94の下面前端(一方の端部)には、後述する取付パネル110に形成された取付穴112の内周縁に係合する前向き横長のスイッチ取付保持用の第1フック体106が一体形成され、スイッチケース50の枠体50aの下面後端(他方の端部)には、取付穴112の内周縁に係合する後向き横長のスイッチ取付保持用の第2フック体108が一体形成されている。   Further, similarly to the first embodiment described above, a forward-facing horizontally long switch that engages with an inner peripheral edge of a mounting hole 112 formed in a mounting panel 110 to be described later, at the lower surface front end (one end portion) of the back cover 94. A first hook body 106 for mounting and holding is integrally formed, and a rearward and horizontally long switch mounting and holding that engages with the inner periphery of the mounting hole 112 is provided at the rear lower end (the other end) of the frame 50a of the switch case 50. A second hook body 108 is integrally formed.

1.押ボタンスイッチ装置の取付方法
次に、組み上がった押ボタンスイッチ装置を所定の固定部材の取付位置に取り付ける方法について図15〜図17を参照して説明する。まず、図15に示すように、取付パネル110にスイッチケース50とほぼ同形状の矩形の取付穴112を穿設する。そして、図16の一点鎖線で囲まれた部分に示すように、取付穴112の内周縁に第1フック体106を係合し接合端子57を取付パネル110側の配線パターン部に圧接しつつ、この状態でスイッチケース50を前方へ引っ張ることで、棒ばね100aの付勢力に抗しつつ裏面カバー94をスイッチケース50に対して後方へスライドさせる。
1. Next, a method for attaching the assembled push button switch device to a predetermined fixing member attachment position will be described with reference to FIGS. First, as shown in FIG. 15, a rectangular mounting hole 112 having substantially the same shape as the switch case 50 is formed in the mounting panel 110. Then, as shown in the portion surrounded by the one-dot chain line in FIG. 16, the first hook body 106 is engaged with the inner peripheral edge of the mounting hole 112 and the joining terminal 57 is pressed against the wiring pattern portion on the mounting panel 110 side, By pulling the switch case 50 forward in this state, the back cover 94 is slid backward with respect to the switch case 50 against the urging force of the bar spring 100a.

そして、両フック体106,108間の距離が縮まった状態で、第2フック体108を取付穴112の内周縁に係合させた後、スイッチケース50の前方への引っ張りを解除すれば、棒ばね100aの付勢力により裏面カバー94がスイッチケース50に対して前方へスライドしてもとの状態に戻り、図17に示すように、押ボタンスイッチ装置が取付パネル110の取付穴112に取り付けられると同時に、接続端子57が取付パネル側の配線パターン部に接触してプリント基板56と配線パターン部とが電気的に接続される(図17中の、一点鎖線で囲まれた部分参照)。   Then, in a state where the distance between the hook bodies 106 and 108 is reduced, the second hook body 108 is engaged with the inner peripheral edge of the mounting hole 112, and then the forward pulling of the switch case 50 is released. The back cover 94 is slid forward relative to the switch case 50 by the biasing force of the spring 100a, and the push button switch device is mounted in the mounting hole 112 of the mounting panel 110 as shown in FIG. At the same time, the connection terminal 57 comes into contact with the wiring pattern portion on the mounting panel side, and the printed circuit board 56 and the wiring pattern portion are electrically connected (see the portion surrounded by the one-dot chain line in FIG. 17).

以上のように、本実施形態では、上記した第1実施形態と同様の効果を奏することができると共に、特に、以下の効果を奏することができる。すなわち、押ボタンスイッチ装置の取付穴112への取付時に、スイッチケース50内のプリント基板56に接続され先端部がスイッチケースから露出された接続端子57が、取付穴112側の配線パターン部に接触してプリント基板56が配線パターン部に電気的に接続されるため、押ボタンスイッチ装置の取付穴112への取り付け作業と、押ボタンスイッチ装置の配線作業とを同時に行うことができ作業効率の向上を図ることができる。   As described above, in the present embodiment, the same effects as those of the first embodiment described above can be obtained, and in particular, the following effects can be obtained. That is, when the pushbutton switch device is mounted in the mounting hole 112, the connection terminal 57 that is connected to the printed circuit board 56 in the switch case 50 and whose tip is exposed from the switch case contacts the wiring pattern portion on the mounting hole 112 side. Since the printed circuit board 56 is electrically connected to the wiring pattern portion, the work for attaching the push button switch device to the attachment hole 112 and the work for wiring the push button switch device can be performed simultaneously, thereby improving work efficiency. Can be achieved.

また、スイッチケース50から露出した接続端子57の先端部が、取付パネル110側の配線パターン部に圧接される方向に付勢されているため、押ボタンスイッチ装置が取付パネル110に取り付けられた状態で接続端子57と配線パターン部とを良好に接触させることができ、プリント基板56と配線パターン部とを確実に電気的に接続することができる。このとき、図17に示すように、接続端子57の先端部にはその付勢力に応じた上向きの反作用力が加わるが、この反作用力は支持部50c1に作用することとなり、固着部57aをプリント基板56から剥離させる力としては作用しないため、押ボタンスイッチ装置を取付パネル110に取り付けることにより固着部57aがプリント基板56から剥離するのを効果的に防止できる。   In addition, since the distal end portion of the connection terminal 57 exposed from the switch case 50 is biased in a direction in which it is pressed against the wiring pattern portion on the mounting panel 110 side, the pushbutton switch device is attached to the mounting panel 110. Thus, the connection terminal 57 and the wiring pattern portion can be satisfactorily brought into contact with each other, and the printed circuit board 56 and the wiring pattern portion can be reliably electrically connected. At this time, as shown in FIG. 17, an upward reaction force corresponding to the biasing force is applied to the distal end portion of the connection terminal 57, but this reaction force acts on the support portion 50c1, and the fixing portion 57a is printed. Since it does not act as a force for peeling from the substrate 56, it is possible to effectively prevent the fixing portion 57 a from being peeled from the printed circuit board 56 by attaching the push button switch device to the mounting panel 110.

また、接続端子57は、導電板を片持ち状にその一端がプリント基板56に固着されて他端にばね性が付与されて構成されているため、実用的な構成で接続端子57をスイッチケース50内に設けることができると共に、当該接続端子57介して取付パネル110側の配線パターン部と内部回路部とを確実に電気的に接続できる。   Further, since the connection terminal 57 is configured such that the conductive plate is cantilevered, one end thereof is fixed to the printed circuit board 56 and the other end is provided with a spring property. 50, and the wiring pattern portion on the mounting panel 110 side and the internal circuit portion can be reliably electrically connected via the connection terminal 57.

<第3実施形態>
次に、本発明の第3実施形態について図18を参照して説明する。但し、図18は下面図である。本実施形態が上記第1及び第2実施形態と大きく異なる点は、図18に示すように、本発明の「付勢体」として裏面カバー94aに樹脂ばね100bが一体形成されている点である。その他の構成及び動作は上記第1及び第2実施形態とほぼ同一であるため、上記第1及び第2実施形態と同一な構成については相当符号を付してその構成および動作の説明を省略する。以下、上記第1及び第2実施形態と異なる点を中心に第3実施形態について詳細に説明する。
<Third Embodiment>
Next, a third embodiment of the present invention will be described with reference to FIG. However, FIG. 18 is a bottom view. As shown in FIG. 18, the present embodiment is greatly different from the first and second embodiments in that a resin spring 100b is integrally formed on the back cover 94a as an “urging member” of the present invention. . Since other configurations and operations are substantially the same as those in the first and second embodiments, the same components as those in the first and second embodiments are denoted by the same reference numerals and description of the configurations and operations is omitted. . Hereinafter, the third embodiment will be described in detail with a focus on differences from the first and second embodiments.

図18に示すように、本実施形態では裏面カバー94aは弾性を有する樹脂製であり、裏面カバー94aの後方に樹脂ばね100bが一体形成されている。詳述すれば、裏面カバー94aの後方に長孔100b1が2つ形成され、長孔100b1の後片100b3に凸部100b2が突設されることで樹脂ばね100bが形成されている。このような構成とすれば、凸部100b2が押圧されることにより、後片100b3が弾性変形して長孔100b1が変形し、この長孔100b1が元の形に復元する際の復元力が樹脂ばね100bの付勢力として作用する。そして、樹脂ばね100bの先端部がスイッチケース50に形成された第2フック体108の前方側に係合することで、スイッチケース50に対して裏面カバー94aを相対的に前方側へ付勢している。   As shown in FIG. 18, in this embodiment, the back cover 94a is made of resin having elasticity, and a resin spring 100b is integrally formed behind the back cover 94a. More specifically, two long holes 100b1 are formed behind the back cover 94a, and the protrusions 100b2 project from the rear piece 100b3 of the long hole 100b1 to form the resin spring 100b. With this configuration, when the convex portion 100b2 is pressed, the rear piece 100b3 is elastically deformed to deform the elongated hole 100b1, and the restoring force when the elongated hole 100b1 is restored to the original shape is resin. It acts as a biasing force for the spring 100b. Then, the front end of the resin spring 100 b is engaged with the front side of the second hook body 108 formed on the switch case 50, thereby urging the back cover 94 a relatively forward with respect to the switch case 50. ing.

したがって、上記した第2実施形態と同様に本実施形態の押ボタンスイッチ装置を取付パネル110の取付穴112に取り付けることができる。すなわち、取付穴112の内周縁に第1フック体106を係合し接合端子57を取付パネル110に設けられた配線パターン部に圧接しつつ、この状態でスイッチカバー50を前方へ引っ張ることにより、樹脂ばね100bの付勢力に抗しつつ裏面カバー94aをスイッチケース50に対して後方へスライドさせる。そして、両フック体106,108間の距離が縮まった状態で、第2フック体108を取付穴112の内周縁に係合させた後、スイッチカバー50の前方への引っ張りを解除すれば、樹脂ばね100bの付勢力により裏面カバー94aがスイッチケース50に対して前方へスライドして元の状態に戻り、押ボタンスイッチ装置が取付パネル110の取付穴112に取り付けられると同時に、接続端子57が配線パターン部に接触してプリント基板56と配線パターン部とが電気的に接続される。   Therefore, the push button switch device of this embodiment can be attached to the attachment hole 112 of the attachment panel 110 as in the second embodiment described above. That is, by pulling the switch cover 50 forward in this state while engaging the first hook body 106 with the inner peripheral edge of the mounting hole 112 and pressing the joint terminal 57 to the wiring pattern portion provided on the mounting panel 110, The back cover 94a is slid backward with respect to the switch case 50 while resisting the biasing force of the resin spring 100b. Then, in a state where the distance between the hook bodies 106 and 108 is reduced, the second hook body 108 is engaged with the inner peripheral edge of the mounting hole 112 and then the forward pulling of the switch cover 50 is released. The back cover 94a slides forward with respect to the switch case 50 by the urging force of the spring 100b to return to the original state, and the push button switch device is attached to the attachment hole 112 of the attachment panel 110, and at the same time, the connection terminal 57 is wired. The printed circuit board 56 and the wiring pattern part are electrically connected in contact with the pattern part.

以上のように、本実施形態では、裏面カバー94aに一体形成された樹脂ばね100bによって、裏面カバー94aをスイッチケース50に対して相対的に付勢するため、部品点数の増加を招くことなく、より実用的な構成で確実に裏面カバー94aを付勢できる。なお、スイッチケース50を弾性を有する樹脂で構成し、本発明の「付勢体」として、上記した樹脂ばね100bと同様の構成の樹脂ばねをスイッチケース50に一体形成して、その先端部が裏面カバー94に係合して該裏面カバー94を付勢するようにしてもよい。   As described above, in the present embodiment, the back cover 94a is biased relatively to the switch case 50 by the resin spring 100b integrally formed with the back cover 94a, so that the number of parts is not increased. The back cover 94a can be reliably urged with a more practical configuration. The switch case 50 is made of a resin having elasticity, and a resin spring having the same configuration as the resin spring 100b described above is integrally formed in the switch case 50 as the “biasing member” of the present invention, and the tip portion thereof is formed. The back cover 94 may be urged by engaging with the back cover 94.

なお、本発明は上記した実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行うことが可能である。例えば、上記した実施形態では本発明の電気機器として「押ボタンスイッチ装置」を例に挙げて説明したが、電気機器としてはこれに限られず、文字、図形等を表示する表示手段としての液晶ディスプレイ、LEDディスプレイ、有機ELディスプレイ、またはLEDなどの発光手段を備えた表示灯等、種々の電気機器に本発明を適用することができる。また、表示手段及び発光手段と、押ボタンスイッチ装置等を組み合わせた電気機器にも本発明を適用することができる。特に薄型化が要求される電気機器についてより好適であり、例えば電気機器として文字、図形等を表示する表示手段と押ボタンスイッチ装置とを組み合わせたものに本発明を採用することで、自動販売機の薄型化を図ったり、エレベータの操作部の薄型化を図ったりすることができる。   The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the “push button switch device” has been described as an example of the electric device of the present invention. However, the electric device is not limited to this, and a liquid crystal display as a display unit that displays characters, figures, and the like. The present invention can be applied to various electric devices such as LED lamps, organic EL displays, or indicator lamps equipped with light emitting means such as LEDs. Further, the present invention can also be applied to an electric device in which a display unit and a light emitting unit are combined with a push button switch device or the like. In particular, the present invention is more suitable for electrical devices that are required to be thinned. For example, the present invention is applied to a combination of a display unit that displays characters, figures, and the like and a push button switch device. It is possible to reduce the thickness of the elevator, and it is possible to reduce the thickness of the operation section of the elevator.

また、上記した実施形態では、裏面カバー94,94aをスイッチケース50に対して相対的に前後方向にスライド自在に取り付けているが、裏面カバー94,94aのスライド方向としては前後方向に限られず、左右方向等、どのような方向であってもよい。また、取付パネル110に形成される取付孔112の形状はどのような形状であってもよく、要は第1及び第2フック体106,108が係合できる形状であればどのような形状であってもよい。また、第1及び第2フック体106,108は、それぞれ裏面カバー94,94a及びスイッチケース50に必ずしも一体形成されていなくともよい。   In the above-described embodiment, the back covers 94 and 94a are attached to be slidable in the front-rear direction relative to the switch case 50. However, the sliding direction of the back covers 94 and 94a is not limited to the front-rear direction. Any direction such as a horizontal direction may be used. Further, the mounting hole 112 formed in the mounting panel 110 may have any shape. In short, any shape is acceptable as long as the first and second hook bodies 106 and 108 can be engaged with each other. There may be. Further, the first and second hook bodies 106 and 108 do not necessarily have to be integrally formed with the back covers 94 and 94a and the switch case 50, respectively.

また、アルミニウムや鉄等の金属製のパネル、樹脂製のパネルまたはプリント基板を取付パネル110として採用できる。特に、上記した第2及び第3実施形態において、取付パネル110としてプリント基板を採用することで、取付穴112の周縁部に配線パターン部を容易に設けることができる。また、金属製あるいは樹脂製の取付パネル110の取付孔112の周縁部にプリント基板を配設することで配線パターン部を構成してもよい。   Further, a panel made of metal such as aluminum or iron, a panel made of resin, or a printed board can be adopted as the mounting panel 110. In particular, in the second and third embodiments described above, by using a printed circuit board as the mounting panel 110, the wiring pattern portion can be easily provided on the peripheral edge of the mounting hole 112. Further, the wiring pattern portion may be configured by disposing a printed board at the peripheral portion of the mounting hole 112 of the mounting panel 110 made of metal or resin.

また、本発明の「付勢体」としては上記した構成に限られず、例えば、一端部がスイッチケース50または裏面カバー94のいずれか一方に固定され他端部が他方に係合してスイッチケース50に対して裏面カバー94を相対的に付勢する棒ばねであってもよい。このような構成としても、棒ばねによって裏面カバー94をスイッチケース50に対して相対的に付勢して、実用的な構成で確実に裏面カバー94を付勢できる。このように、本発明の「付勢体」としては上記した棒ばね100,100a、樹脂ばね100b以外にもコイルスプリング等、種々のものを採用することができる。要は、スイッチケース50に対して裏面カバー94を相対的に付勢することができればどのような構成であってもよい。   In addition, the “biasing body” of the present invention is not limited to the above-described configuration. For example, one end is fixed to either the switch case 50 or the back cover 94 and the other end is engaged with the other. A bar spring that biases the back cover 94 relative to 50 may be used. Even with such a configuration, the back cover 94 can be biased relatively to the switch case 50 by the bar spring, and the back cover 94 can be reliably biased with a practical configuration. Thus, as the “biasing body” of the present invention, various things such as a coil spring can be adopted in addition to the above-described bar springs 100 and 100a and the resin spring 100b. In short, any configuration may be used as long as the back cover 94 can be urged relative to the switch case 50.

また、押圧体84の支点をスイッチケース50に形成した段部88により構成したが、段部88に代えて、突起その他の突部により支点を構成してもよく、或いは、押圧体84側に設けた突部や、該突部とスイッチケース50側の凹部との組み合わせにより支点を構成してもよい。   Further, the fulcrum of the pressing body 84 is configured by the stepped portion 88 formed in the switch case 50. However, instead of the stepped portion 88, the fulcrum may be configured by a protrusion or other protruding portion, or on the pressing body 84 side. You may comprise a fulcrum with the combination of the provided protrusion and this protrusion and the recessed part by the side of the switch case 50. As shown in FIG.

また、上記した実施形態では、ラバー体66及びタクトスイッチ58を押圧体84の付勢手段とした場合について説明したが、押圧体84の付勢のために専用ばねやその他のゴム等の弾性部材を付勢手段として設けてもよいのは勿論である。   In the above-described embodiment, the case where the rubber body 66 and the tact switch 58 are used as the biasing means of the pressing body 84 has been described. However, an elastic member such as a dedicated spring or other rubber is used to bias the pressing body 84. Of course, may be provided as the biasing means.

また、操作体70に付勢力を与えるラバー体66は、特に設ける必要はなく、タクトスイッチ58をはじめとするその他のスイッチの操作力のみで押圧体84を介して操作体70に上向きの付勢力を与えるようにしてもよい。   Further, the rubber body 66 that applies the urging force to the operating body 70 is not particularly required, and the upward urging force is applied to the operating body 70 via the pressing body 84 only by the operating force of other switches such as the tact switch 58. May be given.

また、上記した実施形態ではスイッチケース50をはじめ、操作体70を平面視矩形にした例を示したが、円形その他の対称形状であってもよいのは勿論であり、この場合にも上記した実施形態と同等の効果を得ることができる。   In the above-described embodiment, the switch case 50 and the operation body 70 are rectangular in plan view. However, it is of course possible to use a circular shape or other symmetric shapes. An effect equivalent to that of the embodiment can be obtained.

また、上記した実施形態では、操作体70に押ボタン部72を着脱自在に装着するように構成したが、操作体70に押ボタン部72が一体化された構成であっても構わない。   In the above-described embodiment, the push button portion 72 is detachably attached to the operating body 70, but the push button portion 72 may be integrated with the operating body 70.

さらに、押ボタンスイッチ装置として、必ずしもLED60やその他ランプ等の発光素子や導光部材62などを内蔵する必要はない。   Furthermore, it is not always necessary to incorporate the light emitting element such as the LED 60 and other lamps, the light guide member 62, and the like as the push button switch device.

また、スイッチケース50に配設するスイッチも上記したタクトスイッチ60に限定されるものではなく、何らかの操作力を発生し得るスイッチであればよく、例えばリーフスイッチであってもよい。さらに、上記した実施形態のタクトスイッチ60は、押圧によりオンする(いわゆるa接点)として説明したがオフする(いわゆるb接点)構成でもよい。   Further, the switch disposed in the switch case 50 is not limited to the tact switch 60 described above, and may be any switch that can generate some operating force, for example, a leaf switch. Further, the tact switch 60 of the above-described embodiment has been described as being turned on by pressing (so-called a contact), but may be configured to be turned off (so-called b contact).

また、タクトスイッチ60のような有接点スイッチ以外に無接点スイッチを用いてもよく、この場合にはラバー体66のような可撓性を有する部材を設けて、ラバー体66の如き可撓性部材の復元力を押圧体84の一端(前端)の付勢力とするのが好ましい。   Further, a contactless switch other than the contact switch such as the tact switch 60 may be used. In this case, a flexible member such as the rubber body 66 is provided, and the flexibility such as the rubber body 66 is provided. It is preferable that the restoring force of the member is an urging force at one end (front end) of the pressing body 84.

ところで、本発明の電気機器の取付構造は、上記した実施形態において説明した如く各種電気機器に適用でき、特に薄型の電気機器に好適である。   By the way, the mounting structure of the electric device of the present invention can be applied to various electric devices as described in the above embodiment, and is particularly suitable for a thin electric device.
