Description

本発明は、スイッチ装置用の操作装置、および、当該操作装置を用いるスイッチ装置に関する。 The present invention relates to an operating device for a switch device and a switch device using the operating device.

従来より、様々なスイッチ装置が実用されている。例えば、特許文献１では、ハンドルの回転操作により内部のスイッチの接点部を動作させるセレクタスイッチが開示されている。具体的に、特許文献１のスイッチ装置では、カムがハンドルの軸部に結合され、ハンドルの回転操作に伴ってカムが回転する。これにより、スイッチの接点を動作させる操作プレートが、カムの外周面上に形成されたカム山に従って軸方向に移動する。 Conventionally, various switch devices have been put into practical use. For example, Patent Document 1 discloses a selector switch that operates a contact portion of an internal switch by rotating a handle. Specifically, in the switch device of Patent Document 1, the cam is coupled to the shaft portion of the handle, and the cam rotates as the handle is rotated. As a result, the operation plate for operating the contact of the switch moves in the axial direction according to the cam crest formed on the outer peripheral surface of the cam.

Held in either. The cam 43 and the pair of leaf springs 23 serve as an angular position holding portion that holds the angular position of the cylindrical portion 412. Depending on the design of the switch device 1, the angular position holding unit may be realized using a magnet or the like. In addition, two or four or more holding angle positions may be set.

図１および図３に示すように、ケース上面部２１１の上面は、既述のカバー部３により覆われる。カバー部３には、中心軸Ｊ１を中心とする円弧状の開口３１１（以下、「カバー開口３１１」という。）が形成される。操作部本体４１の突出部４１３は、カバー開口３１１内に配置され、カバー開口３１１に沿って中心軸Ｊ１を中心とする周方向に移動可能となる。すなわち、突出部４１３の周方向への移動が、カバー開口３１１により案内される。突出部４１３の先端は、カバー部３よりも上方に位置する。カバー部３の上方において、突出部４１３の先端には、キャップ部４９が取り付けられる。中心軸Ｊ１を中心とする径方向において、キャップ部４９の幅はカバー開口３１１の幅よりも大きい。図３に示すように、筒状部４１２から片持ち状態にて伸びる接続部４１１は、カバー部３の上面部３１およびケース上面部２１１により、微小な隙間を空けて上下から挟まれる。接続部４１１の厚さは、例えば、０．５ミリメートル（ｍｍ）以上、かつ、４ｍｍ以下であり、本実施の形態では、１ｍｍ以上、かつ、２ｍｍ以下である。 As shown in FIGS. 1 and 3, the upper surface of the case upper surface portion 211 is covered with the cover portion 3 described above. The cover 3 is formed with an arc-shaped opening 311 (hereinafter referred to as “cover opening 311”) centered on the central axis J1. The protruding portion 413 of the operation portion main body 41 is disposed in the cover opening 311 and can move in the circumferential direction around the central axis J1 along the cover opening 311. That is, the movement of the protrusion 413 in the circumferential direction is guided by the cover opening 311. The tip of the protruding portion 413 is located above the cover portion 3. A cap portion 49 is attached to the tip of the protruding portion 413 above the cover portion 3. In the radial direction around the central axis J1, the width of the cap portion 49 is larger than the width of the cover opening 311. As shown in FIG. 3, the connecting portion 411 extending in a cantilever state from the tubular portion 412 is sandwiched from above and below by a top surface portion 31 and a case top surface portion 211 of the cover portion 3 with a small gap. The thickness of the connection part 411 is 0.5 millimeter (mm) or more and 4 mm or less, for example, and is 1 mm or more and 2 mm or less in this Embodiment.

スイッチ装置１を操作する際には、操作者が指の腹によりキャップ部４９を介して突出部４１３を下方に押さえつつ、または、指先にてキャップ部４９を介して突出部４１３を摘まみつつ、突出部４１３をカバー開口３１１に沿って移動（スライド）する。これにより、操作部本体４１が、軸部である筒状部４１２を中心として回動し、各板ばね２３の係合部２３１がいずれかのカム凹部４３４に係合する保持角度位置に、接続部４１１が配置される。このように、スイッチ装置１では、接続部４１１および突出部４１３を操作部として操作者による操作が行われる。なお、突出部４１３を移動する際には、接続部４１１がケース上面部２１１の上面（または、カバー部３の上面部３１の下面）上を摺動してもよい。このとき、ケース上面部２１１は、側面部２１２により四方から支持されるため、ほとんど変形する（撓む）ことはない（カバー部３の上面部３１において同様）。図４および図５では、３個の保持角度位置のうち中央の保持角度位置における接続部４１１および可動接点４４を実線にて示し、両端の保持角度位置における接続部４１１および可動接点４４を二点鎖線にて示している。 When operating the switch device 1, the operator presses the protruding portion 413 downward through the cap portion 49 with the belly of the finger, or grasps the protruding portion 413 through the cap portion 49 with the fingertip. The protrusion 413 is moved (slid) along the cover opening 311. As a result, the operating portion main body 41 rotates around the cylindrical portion 412 that is the shaft portion, and is connected to the holding angular position where the engaging portion 231 of each leaf spring 23 engages any one of the cam recesses 434. A part 411 is arranged. As described above, in the switch device 1, an operation by the operator is performed using the connection portion 411 and the protruding portion 413 as the operation portion. In addition, when moving the protrusion part 413, the connection part 411 may slide on the upper surface of the case upper surface part 211 (or the lower surface of the upper surface part 31 of the cover part 3). At this time, since the case upper surface portion 211 is supported from four sides by the side surface portion 212, it hardly deforms (bends) (the same applies to the upper surface portion 31 of the cover portion 3). 4 and 5, the connection portion 411 and the movable contact 44 at the central holding angle position among the three holding angle positions are indicated by solid lines, and the connection portion 411 and the movable contact 44 at the holding angle positions at both ends are two points. It is indicated by a chain line.

図３に示す可動接点４４の先端部４４２には、プリント基板２２に向かって突出する凸形状にプレス加工が施されている。筒状部４１２の回動により、可動接点４４の先端部４４２が、プリント基板２２の上面を周方向に摺動する。プリント基板２２の上面には、例えば２個の固定接点２９が形成される。一の保持角度位置に配置された際における可動接点４４の先端部４４２が一方の固定接点２９に接触し、他の一の保持角度位置に配置された際における可動接点４４の先端部４４２が他方の固定接点２９に接触する。残りの保持角度位置に配置された際における可動接点４４の先端部４４２は、いずれの固定接点２９にも接触しない。したがって、１つの固定接点２９に着目すると、可動接点４４は、周方向に回動して当該固定接点２９と接触および離間する（すなわち、スイッチングが行われる。）。各固定接点２９および可動接点４４は、図示省略の導電性部材（例えば、導電線）を介して、外部の電気回路と接続される。 The tip 442 of the movable contact 44 shown in FIG. 3 is pressed into a convex shape that protrudes toward the printed circuit board 22. By the rotation of the cylindrical portion 412, the distal end portion 442 of the movable contact 44 slides on the upper surface of the printed circuit board 22 in the circumferential direction. For example, two fixed contacts 29 are formed on the upper surface of the printed circuit board 22. The tip 442 of the movable contact 44 when it is arranged at one holding angle position contacts one fixed contact 29, and the tip 442 of the movable contact 44 when it is arranged at the other holding angle position is the other. The fixed contact 29 is contacted. The distal end portion 442 of the movable contact 44 when arranged at the remaining holding angle position does not contact any fixed contact 29. Therefore, paying attention to one fixed contact 29, the movable contact 44 rotates in the circumferential direction and contacts and separates from the fixed contact 29 (that is, switching is performed). Each fixed contact 29 and movable contact 44 are connected to an external electric circuit via a conductive member (for example, a conductive wire) (not shown).

以上のように、スイッチ装置１では、固定接点２９および可動接点４４が、筒状部４１２の所定の角度位置への回動を検出する検出部となる。また、ケース本体２１、操作部本体４１の接続部４１１、筒状部４１２および突出部４１３、並びに、カバー部３を主たる構成要素として、可動接点４４を操作する操作装置１１が実現される。なお、スイッチ装置１は、突出部４１３のスライド動作によりスイッチングを行うスライドスイッチと捉えることもできる。 As described above, in the switch device 1, the fixed contact 29 and the movable contact 44 serve as a detection unit that detects the rotation of the cylindrical portion 412 to a predetermined angular position. Further, the operation device 11 that operates the movable contact 44 is realized with the case main body 21, the connection portion 411 of the operation portion main body 41, the cylindrical portion 412 and the protruding portion 413, and the cover portion 3 as main components. The switch device 1 can also be regarded as a slide switch that performs switching by a sliding operation of the protruding portion 413.

図１に示すように、カバー部３には、開口である複数の窓部３１２が形成される。複数の窓部３１２は、カバー開口３１１の近傍にて、複数の保持角度位置と同じ角度位置に配置される。各保持角度位置に配置された際における接続部４１１の端部と、当該保持角度位置に配置された窓部３１２とが上下方向において重なる。接続部４１１の当該端部（接続部４１１の全体であってもよい。）は、所定の色を有する。したがって、突出部４１３が各保持角度位置に配置された際に、突出部４１３に最も近接する窓部３１２（当該保持角度位置の窓部３１２）を介して、接続部４１１の当該端部の色が、外部から視認可能となる。なお、窓部３１２は開口以外であってもよい。例えば、カバー部３が透明な樹脂にて形成され、複数の窓部３１２を除く領域にシボ加工が施されてもよい。 As shown in FIG. 1, the cover 3 is formed with a plurality of windows 312 that are openings. The plurality of window portions 312 are arranged at the same angular position as the plurality of holding angular positions in the vicinity of the cover opening 311. The end portion of the connection portion 411 when arranged at each holding angle position and the window portion 312 arranged at the holding angle position overlap in the vertical direction. The said edge part of the connection part 411 (The whole connection part 411 may be sufficient) has a predetermined color. Therefore, when the protruding portion 413 is arranged at each holding angle position, the color of the end portion of the connecting portion 411 via the window portion 312 closest to the protruding portion 413 (the window portion 312 at the holding angle position). However, it becomes visible from the outside. The window 312 may be other than the opening. For example, the cover part 3 may be formed of a transparent resin, and a texture process may be applied to an area excluding the plurality of window parts 312.

スイッチ装置１では、図４中に二点鎖線にて示す両端の保持角度位置のそれぞれを超えて外側に（中央の保持角度位置から離れる方向に）、操作者が突出部４１３および接続部４１１を移動させようとすると、下側突起４１５（図３参照）が、円弧状溝２１７の周方向の端のエッジに当接する。すなわち、両端の保持角度位置を外側に大きく超えた位置へと、突出部４１３および接続部４１１が移動することが防止される。このように、ケース上面部２１１に設けられる円弧状溝２１７が、突出部４１３および接続部４１１の回動範囲を制限する回動制限部となる。スイッチ装置１では、ケース上面部２１１における凹部２１４の周方向の端のエッジが接続部４１１と当接して回動制限部としての役割を果たしてもよい。また、カバー部３におけるカバー開口３１１の周方向の端のエッジが突出部４１３と当接して回動制限部としての役割を果たしてもよい。さらに、カバー部３の下面にケース上面部２１１に向かって突出する部位が設けられ、当該部位が、回動制限部として接続部４１１に当接してもよい。 In the switch device 1, the operator moves the protruding portion 413 and the connecting portion 411 beyond the holding angle positions at both ends indicated by a two-dot chain line in FIG. 4 outward (in a direction away from the central holding angle position). When trying to move, the lower protrusion 415 (see FIG. 3) abuts on the edge of the arcuate groove 217 in the circumferential direction. In other words, the protruding portion 413 and the connecting portion 411 are prevented from moving to positions that greatly exceed the holding angle positions at both ends. As described above, the arcuate groove 217 provided in the case upper surface portion 211 serves as a rotation restricting portion that restricts the rotation range of the protruding portion 413 and the connecting portion 411. In the switch device 1, the edge at the end in the circumferential direction of the concave portion 214 in the case upper surface portion 211 may contact the connecting portion 411 and serve as a rotation limiting portion. Further, the edge of the cover opening 311 in the circumferential direction of the cover opening 311 may be in contact with the protruding portion 413 to serve as a rotation restricting portion. Furthermore, a portion that protrudes toward the case upper surface portion 211 may be provided on the lower surface of the cover portion 3, and the portion may contact the connection portion 411 as a rotation restricting portion.

以上に説明したように、スイッチ装置１における操作装置１１では、ケース上面部２１１のケース上面開口２１３に筒状部４１２が挿入され、ケース上面部２１１の上側にてケース上面部２１１に沿って伸びる接続部４１１が筒状部４１２の上部に接続する。接続部４１１には、筒状部４１２から離れた位置においてケース上面部２１１とは反対側に突出する突出部４１３が設けられる。また、ケース上面部２１１との間にて接続部４１１を挟むカバー部３がさらに設けられ、カバー部３には、突出部４１３の周方向への移動を案内するカバー開口３１１が形成される。スイッチ装置１では、筒状部４１２から片持ち状態にて伸びる接続部４１１が、カバー部３およびケース上面部２１１により上下から挟まれ、上下方向への移動が制限される。これにより、突出部４１３の押し込み等により接続部４１１が損傷することを防止しつつ、接続部４１１を薄型化することができる。その結果、軸部の回動を伴う操作装置１１の薄型化、および、軸部の回動によりスイッチングを行うスイッチ装置１の薄型化を容易に実現することができる。また、ケース上面部２１１上の円弧状溝２１７により、接続部４１１の回動範囲を制限することにより、接続部４１１が損傷することをより確実に防止することができる。 As described above, in the operating device 11 in the switch device 1, the cylindrical portion 412 is inserted into the case upper surface opening 213 of the case upper surface portion 211 and extends along the case upper surface portion 211 above the case upper surface portion 211. The connection part 411 connects to the upper part of the cylindrical part 412. The connecting portion 411 is provided with a protruding portion 413 that protrudes to the opposite side of the case upper surface portion 211 at a position away from the tubular portion 412. Further, a cover portion 3 that sandwiches the connection portion 411 with the case upper surface portion 211 is further provided, and the cover portion 3 is formed with a cover opening 311 that guides the movement of the protruding portion 413 in the circumferential direction. In the switch device 1, the connecting portion 411 extending in a cantilevered state from the tubular portion 412 is sandwiched from above and below by the cover portion 3 and the case upper surface portion 211, and movement in the vertical direction is restricted. Thereby, it is possible to reduce the thickness of the connection portion 411 while preventing the connection portion 411 from being damaged by the pushing of the protruding portion 413 or the like. As a result, it is possible to easily realize the thinning of the operating device 11 accompanied by the rotation of the shaft portion and the thinning of the switch device 1 that performs switching by the rotation of the shaft portion. Further, the arc-shaped groove 217 on the case upper surface portion 211 restricts the rotation range of the connection portion 411, so that the connection portion 411 can be more reliably prevented from being damaged.

突出部４１３を、軸部から離れた位置にて周方向に移動する操作装置１１では、軸部の中心軸上に設けられる摘まみ部を回動する操作に比べて、操作性を向上することができる。また、操作装置１１では、ケース上面開口２１３の環状の縁と筒状部４１２の外周面との間に環状のシール部４２を設けるのみにより、可動接点４４が配置される空間内への液体の浸入を容易に防止することが可能となる。すなわち、突出部４１３が移動可能な領域に比べて小さい領域を覆うシール部４２により、スイッチ装置１における防水構造を容易に実現することができる。なお、スイッチ装置１が各種機器に設けられる際には、ケース本体２１の側面部２１２が、当該機器の筐体により囲まれるため、スイッチ装置１の下方から上記空間内に液体が浸入することはない。 In the operating device 11 that moves the protruding portion 413 in the circumferential direction at a position away from the shaft portion, the operability is improved as compared with the operation of rotating the knob provided on the central axis of the shaft portion. Can do. Further, in the operating device 11, the liquid is introduced into the space in which the movable contact 44 is disposed only by providing the annular seal portion 42 between the annular edge of the case upper surface opening 213 and the outer peripheral surface of the cylindrical portion 412. Intrusion can be easily prevented. That is, the waterproof structure in the switch device 1 can be easily realized by the seal portion 42 that covers a region smaller than the region in which the protruding portion 413 can move. When the switch device 1 is provided in various devices, the side surface portion 212 of the case main body 21 is surrounded by the housing of the device, so that liquid may enter the space from below the switch device 1. Absent.

図６は、スイッチ装置１の他の例を示す平面図であり、図７はカバー部３を取り除いた状態におけるスイッチ装置１を示す平面図である。図６のスイッチ装置１では、カバー部３の複数の窓部３１２の位置および形状が、図１のスイッチ装置１と相違する。また、接続部４１１に、後述する複数の表示部４１６が設けられる。他の構成は、図１のスイッチ装置１と同様であり、同じ構成に同じ符号を付す。 FIG. 6 is a plan view showing another example of the switch device 1, and FIG. 7 is a plan view showing the switch device 1 in a state where the cover portion 3 is removed. In the switch device 1 of FIG. 6, the positions and shapes of the plurality of window portions 312 of the cover portion 3 are different from those of the switch device 1 of FIG. 1. The connection unit 411 is provided with a plurality of display units 416 to be described later. Other configurations are the same as those of the switch device 1 of FIG. 1, and the same components are denoted by the same reference numerals.

図６に示すように、複数の窓部３１２は、カバー開口３１１の近傍にて、複数の保持角度位置と同じ角度位置に配置される。図６の例では、３個の矩形の窓部３１２がおよそ周方向に沿って配置される。また、中心軸Ｊ１を中心とする径方向において、複数の窓部３１２の位置が互いに相違する。図７に示すように、接続部４１１では、カバー部３に対向する上面において径方向の複数の位置に、所定の文字や記号、図形等を記した複数の表示部４１６が設けられる。図７では、それぞれ「１」、「２」、「３」と記した３個の表示部４１６が設けられる。複数の表示部４１６の径方向の位置は、複数の窓部３１２の径方向の位置とそれぞれ同じである。 As shown in FIG. 6, the plurality of window portions 312 are arranged at the same angular position as the plurality of holding angular positions in the vicinity of the cover opening 311. In the example of FIG. 6, three rectangular window portions 312 are arranged approximately along the circumferential direction. Further, the positions of the plurality of window portions 312 are different from each other in the radial direction around the central axis J1. As shown in FIG. 7, the connection portion 411 is provided with a plurality of display portions 416 in which predetermined characters, symbols, figures, and the like are written at a plurality of radial positions on the upper surface facing the cover portion 3. In FIG. 7, three display portions 416 denoted as “1”, “2”, and “3” are provided. The radial positions of the plurality of display portions 416 are the same as the radial positions of the multiple window portions 312, respectively.

図６中に破線にて示す中央の保持角度位置に接続部４１１が配置される際には、中央の窓部３１２に当該窓部３１２と同じ径方向の位置の表示部４１６の内容が表示される。また、図６中に二点鎖線にて示す左側の保持角度位置に接続部４１１が配置される際には、左側の窓部３１２に当該窓部３１２と同じ径方向の位置の表示部４１６の内容が表示される。さらに、図６中に二点鎖線にて示す右側の保持角度位置に接続部４１１が配置される際には、右側の窓部３１２に当該窓部３１２と同じ径方向の位置の表示部４１６の内容が表示される。 When the connecting portion 411 is arranged at the central holding angle position indicated by the broken line in FIG. 6, the content of the display portion 416 at the same radial position as the window portion 312 is displayed on the central window portion 312. The In addition, when the connection portion 411 is disposed at the left holding angle position indicated by a two-dot chain line in FIG. 6, the display portion 416 at the same radial position as the window portion 312 is disposed on the left window portion 312. The contents are displayed. Furthermore, when the connection portion 411 is disposed at the right holding angle position indicated by the two-dot chain line in FIG. 6, the display portion 416 at the same radial position as the window portion 312 is disposed on the right window portion 312. The contents are displayed.

以上のように、図６のスイッチ装置１では、外部から内部が視認可能である一の窓部３１２および他の一の窓部３１２がカバー部３に設けられ、周方向および径方向の双方の位置が、これらの窓部３１２で互いに相違する。また、接続部４１１において、径方向の位置が当該一の窓部３１２と同じである一の表示部４１６、および、径方向の位置が当該他の一の窓部３１２と同じである他の一の表示部４１６が設けられる。これにより、操作部（接続部４１１）の角度位置に応じて複数の窓部３１２に異なる表示を行うことができる。なお、複数の表示部４１６は、互いに異なるものとして識別されるのであるならば、文字、記号、図形以外であってよく、例えば、異なる色に着色された複数の領域であってもよい。 As described above, in the switch device 1 in FIG. 6, one window portion 312 and the other one window portion 312 that are visible from the outside are provided in the cover portion 3, and both the circumferential direction and the radial direction are provided. The positions of the windows 312 are different from each other. In addition, in the connection portion 411, one display portion 416 whose radial position is the same as that of the one window portion 312 and another one whose radial position is the same as that of the other one window portion 312. The display unit 416 is provided. Thereby, different displays can be performed on the plurality of window portions 312 according to the angular position of the operation portion (connection portion 411). Note that the plurality of display units 416 may be other than characters, symbols, and figures as long as they are identified as different from each other, and may be, for example, a plurality of regions colored in different colors.

図８は本発明の第２の実施の形態に係るスイッチ装置１ａを示す平面図であり、図９はカバー部３を取り除いた状態におけるスイッチ装置１ａを示す平面図であり、図１０は図８中の矢印Ｂ−Ｂの位置におけるスイッチ装置１ａの断面図である。図８ないし図１０に示すスイッチ装置１ａでは、突出部４１３ａが接続部４１１の長手方向（径方向に沿う方向）に移動可能である。また、カバー開口３１１ａの形状が、図１のスイッチ装置１におけるカバー開口３１１の形状と相違する。スイッチ装置１ａにおける他の構成は、図１のスイッチ装置１と同様であり、同じ構成に同じ符号を付す。 FIG. 8 is a plan view showing a switch device 1a according to the second embodiment of the present invention, FIG. 9 is a plan view showing the switch device 1a in a state where the cover portion 3 is removed, and FIG. It is sectional drawing of the switch apparatus 1a in the position of arrow BB in the inside. In the switch device 1a shown in FIGS. 8 to 10, the protruding portion 413a is movable in the longitudinal direction (direction along the radial direction) of the connecting portion 411. Further, the shape of the cover opening 311a is different from the shape of the cover opening 311 in the switch device 1 of FIG. Other configurations of the switch device 1a are the same as those of the switch device 1 of FIG. 1, and the same reference numerals are given to the same configurations.

図９および図１０に示すように、接続部４１１は、長手方向に伸びるガイド孔４１７を有する。また、接続部４１１の下面には、ガイド孔４１７よりも僅かに広い領域が窪んだ包括凹部４１８が形成される。ガイド孔４１７は、包括凹部４１８の底面（ケース上面部２１１側を向く面）にて開口する。突出部４１３ａは、接続部４１１と別の部材として形成され、ケース上面部２１１側に配置される端部において、上下方向に垂直な方向に広がるフランジ部４１３１を有する。突出部４１３ａはガイド孔４１７に挿入される。突出部４１３ａのフランジ部４１３１は、包括凹部４１８のガイド孔４１７を除く領域の一部と、ケース上面部２１１の上面との間に挟まれる。これにより、突出部４１３ａは、ガイド孔４１７に沿って接続部４１１の長手方向に移動可能な状態で、接続部４１１に対して支持される。図８に示すように、カバー部３のカバー開口３１１ａは、上下反転したＶ字状である。したがって、中心軸Ｊ１を中心とする周方向の角度位置によって、カバー開口３１１ａの部位の径方向の位置が相違する。 As shown in FIGS. 9 and 10, the connecting portion 411 has a guide hole 417 extending in the longitudinal direction. In addition, a comprehensive recess 418 in which a region slightly wider than the guide hole 417 is recessed is formed on the lower surface of the connection portion 411. The guide hole 417 opens at the bottom surface of the comprehensive recess 418 (the surface facing the case upper surface portion 211 side). The protruding portion 413a is formed as a separate member from the connecting portion 411, and has a flange portion 4131 that extends in a direction perpendicular to the vertical direction at an end portion disposed on the case upper surface portion 211 side. The protrusion 413a is inserted into the guide hole 417. The flange portion 4131 of the protruding portion 413a is sandwiched between a part of the region excluding the guide hole 417 of the comprehensive recess 418 and the upper surface of the case upper surface portion 211. Accordingly, the protruding portion 413a is supported with respect to the connecting portion 411 in a state in which the protruding portion 413a is movable in the longitudinal direction of the connecting portion 411 along the guide hole 417. As shown in FIG. 8, the cover opening 311 a of the cover portion 3 has a V shape that is inverted upside down. Accordingly, the radial position of the portion of the cover opening 311a differs depending on the angular position in the circumferential direction around the central axis J1.

図１１は突出部４１３ａを右側の保持角度位置に配置した際におけるスイッチ装置１ａを示す平面図であり、図１２は、図１１に示すスイッチ装置１ａにおいて、カバー部３を取り除いた状態を示す図である。図８に示す中央の保持角度位置から図１１に示す右側の保持角度位置へと突出部４１３ａ（および接続部４１１）を移動する際には、図９および図１２に示すように、突出部４１３ａがガイド孔４１７に沿って接続部４１１の長手方向にも移動する。すなわち、中央の保持角度位置から右側の保持角度位置への移動において、突出部４１３ａが中心軸Ｊ１を中心とする周方向および径方向の双方に移動する。中央の保持角度位置から左側の保持角度位置へと突出部４１３ａを移動する場合も、同様に、突出部４１３ａが周方向および径方向の双方に移動する。スイッチ装置１ａでは、突出部４１３ａの一の保持角度位置から他の一の保持角度位置への移動により、スイッチングが行われる。 11 is a plan view showing the switch device 1a when the protruding portion 413a is arranged at the holding angle position on the right side, and FIG. 12 is a diagram showing a state in which the cover portion 3 is removed from the switch device 1a shown in FIG. It is. When moving the protruding portion 413a (and the connecting portion 411) from the central holding angle position shown in FIG. 8 to the right holding angle position shown in FIG. 11, as shown in FIGS. 9 and 12, the protruding portion 413a is moved. Moves in the longitudinal direction of the connecting portion 411 along the guide hole 417. That is, in the movement from the central holding angle position to the right holding angle position, the protrusion 413a moves both in the circumferential direction and in the radial direction around the central axis J1. Similarly, when the protrusion 413a is moved from the central holding angle position to the left holding angle position, the protrusion 413a moves in both the circumferential direction and the radial direction. In the switch device 1a, switching is performed by movement from one holding angle position of the protruding portion 413a to another holding angle position.

以上に説明したように、スイッチ装置１ａにおける操作装置１１では、突出部４１３ａが接続部４１１の長手方向に沿って移動可能である。これにより、カバー開口３１１ａが、径方向の位置が異なる複数の部位を含むことができ、突出部４１３ａのスライド方向を自在に決定することが可能となる。例えば、図８に示す形状のカバー開口３１１ａでは、突出部４１３ａを周方向に沿って移動する際に、中央の保持角度位置にて突出部４１３ａの移動方向が大幅に変化する。これにより、突出部４１３ａが中央の保持角度位置を行き過ぎること（誤操作）を防止して、スイッチ装置１ａの操作の確実性を向上することができる。 As described above, in the operating device 11 in the switch device 1a, the protruding portion 413a is movable along the longitudinal direction of the connecting portion 411. Thereby, the cover opening 311a can include a plurality of portions having different radial positions, and the sliding direction of the protruding portion 413a can be freely determined. For example, in the cover opening 311a having the shape shown in FIG. 8, when the protruding portion 413a is moved along the circumferential direction, the moving direction of the protruding portion 413a is significantly changed at the central holding angle position. Thereby, it can prevent that the protrusion part 413a goes too far in the center holding | maintenance angle position (erroneous operation), and can improve the reliability of operation of the switch apparatus 1a.

スイッチ装置１ａにおけるカバー開口３１１ａは、少なくとも周方向への突出部４１３ａの移動を案内する形状であればよく、例えば、図１３に示すように、横方向に真っ直ぐに延びるカバー開口３１１ａが形成されてもよい。図１３のスイッチ装置１ａでは、突出部４１３ａを横方向に真っ直ぐに移動することにより、保持角度位置が切り替えられる。また、スイッチ装置１ａでは、軸部材である筒状部４１２の周囲のみにシール部４２が設けられる（図１０参照）。すなわち、突出部４１３ａが移動可能な領域に比べて小さい領域を覆うシール部４２が用いられる。これにより、突出部４１３ａのスライド動作に起因してスイッチングを行うスイッチ装置１ａにおいて、接点が配置される空間を容易に密閉することができる。 The cover opening 311a in the switch device 1a may have any shape that guides at least the movement of the protruding portion 413a in the circumferential direction. For example, as shown in FIG. 13, a cover opening 311a that extends straight in the lateral direction is formed. Also good. In the switch device 1a of FIG. 13, the holding angle position is switched by moving the protrusion 413a straight in the lateral direction. Moreover, in the switch apparatus 1a, the seal part 42 is provided only around the cylindrical part 412 which is a shaft member (see FIG. 10). That is, the seal portion 42 that covers a region smaller than the region where the protruding portion 413a can move is used. Thereby, in the switch apparatus 1a which switches based on the sliding operation | movement of the protrusion part 413a, the space where a contact is arrange | positioned can be sealed easily.

また、図１４に示す形状のカバー開口３１１ａが、カバー部３に形成されてもよい。この場合、接続部４１１の長手方向における長さが、図９に示すガイド孔４１７よりも長いガイド孔４１７ａが接続部４１１に形成される。図１４のスイッチ装置１ａでは、左側または右側の保持角度位置から中央の保持角度位置へと突出部４１３ａを移動する際に、突出部４１３ａを図１４中の縦方向および横方向に順に移動させる必要がある。すなわち、一の保持角度位置から突出部４１３ａを一の方向に移動し、続いて、当該方向とは異なる他の一の方向に移動することにより、突出部４１３ａを、当該保持角度位置に隣接する次の保持角度位置に配置することが可能となる。これにより、図１４のスイッチ装置１ａでは、誤操作をより確実に防止することが実現される。 Further, a cover opening 311 a having a shape shown in FIG. 14 may be formed in the cover portion 3. In this case, a guide hole 417a having a longer length in the longitudinal direction of the connection portion 411 than the guide hole 417 shown in FIG. In the switch device 1a of FIG. 14, when the protrusion 413a is moved from the left or right holding angle position to the center holding angle position, it is necessary to move the protrusion 413a sequentially in the vertical direction and the horizontal direction in FIG. There is. That is, the protruding portion 413a is adjacent to the holding angle position by moving the protruding portion 413a in one direction from one holding angle position and then moving in another direction different from the direction. It can be arranged at the next holding angle position. Thereby, in switch device 1a of Drawing 14, it is realized to prevent erroneous operation more certainly.

図１５は、スイッチユニット１０を示す図である。スイッチユニット１０は、複数のスイッチ装置１（スイッチ装置１ａであってもよい。）が固定可能な固定ユニット１０１を備え、固定ユニット１０１には、互いに同じ構造を有する複数の固定枠１０２が配列形成される。図１５では、固定ユニット１０１および後述の回路基板１０４のみ断面を示している。 FIG. 15 is a diagram illustrating the switch unit 10. The switch unit 10 includes a fixed unit 101 to which a plurality of switch devices 1 (which may be the switch device 1a) can be fixed. A plurality of fixed frames 102 having the same structure are arranged in the fixed unit 101. Is done. In FIG. 15, only the fixed unit 101 and a circuit board 104 described later are shown in cross section.

スイッチ装置１のケース２の側面部２１２には外側に突出する外側突起２１８が設けられ、外側突起２１８が、各固定枠１０２に形成された凹部１０３に係合することにより、スイッチ装置１が固定枠１０２に固定される。もちろん、スイッチ装置１の側面部２１２に凹部が設けられ、固定枠に突起が設けられてよい。固定ユニット１０１の内部の底面には専用の回路基板１０４が設けられる。また、各スイッチ装置１におけるケース２の底面部（例えば、プリント基板２２）の下面には、各固定接点２９および可動接点４４に接続された接触子２２１が設けられる。スイッチ装置１が固定枠１０２に取り付けられた状態において、接触子２２１は、回路基板１０４上の端子に接触する。これにより、回路基板１０４および接触子２２１を介して、スイッチ装置１に対して電流が供給される。 The side surface 212 of the case 2 of the switch device 1 is provided with an outer protrusion 218 that protrudes outward. The outer protrusion 218 engages with the recess 103 formed in each fixing frame 102, thereby fixing the switch device 1. It is fixed to the frame 102. Of course, a concave portion may be provided on the side surface portion 212 of the switch device 1, and a protrusion may be provided on the fixed frame. A dedicated circuit board 104 is provided on the bottom surface inside the fixed unit 101. Further, a contact 221 connected to each fixed contact 29 and the movable contact 44 is provided on the lower surface of the bottom surface portion (for example, the printed circuit board 22) of the case 2 in each switch device 1. In a state where the switch device 1 is attached to the fixed frame 102, the contact 221 contacts a terminal on the circuit board 104. Thereby, a current is supplied to the switch device 1 via the circuit board 104 and the contact 221.

以上のように、スイッチユニット１０では、複数の固定枠１０２のうちの任意の固定枠１０２に、スイッチ装置１が取付可能であり、スイッチ装置１が固定枠１０２に取り付けられることにより、固定ユニット１０１の回路基板１０４上の端子と、スイッチ装置１の接触子２２１との電気的な接続が完了する。これにより、スイッチ装置１の固定ユニット１０１への取付、および、回路基板１０４との電気的な接続をワンタッチにて同時に行うことができる。その結果、スイッチ装置１の固定ユニット１０１への組み込みに係る工数を削減することができる。 As described above, in the switch unit 10, the switch device 1 can be attached to an arbitrary fixed frame 102 among the plurality of fixed frames 102, and the switch unit 1 is attached to the fixed frame 102, thereby fixing the fixed unit 101. The electrical connection between the terminal on the circuit board 104 and the contact 221 of the switch device 1 is completed. Thereby, attachment to the fixed unit 101 of the switch apparatus 1 and electrical connection with the circuit board 104 can be simultaneously performed by one touch. As a result, it is possible to reduce the man-hours related to the incorporation of the switch device 1 into the fixed unit 101.
