Description

【発明の詳細な説明】 【0001】 【発明の属する技術分野】本発明は、ひとつの操作軸で回転操作と軸線方向への押圧操作とが行える複合操作型電気部品に関する。 BACKGROUND OF THE INVENTION [0001] [Technical Field of the Invention The present invention relates to one of the composite electric component that allows the pressing operation to the rotating operation and the axis direction by the operation shaft. 【0002】 【従来の技術】操作軸の回転操作によりエンコーダ等の回転操作型電気部品として動作し、同じ操作軸の押し込み操作によりプッシュスイッチ等の押圧操作型電気部品として動作する複合操作型電気部品は、操作形態の異なる2種類の電気部品の操作軸やケースを共通化できるという利点を有するため、これを組み込むことで各種電子機器の多機能化や小型化が促進しやすくなる。 [0002] operates as a rotary electric component such as an encoder by rotation of the operating shaft, composite operation type electric component to be operated by pushing operation of the same operating axis as the pressing operation type electric component such as a push switch since having the advantage of sharing the two electrical components of the operating shaft and the case of different control mode, comprising various multifunctional and miniaturization is easily promote electronic equipment by incorporating the same. 【0003】この種の複合操作型電気部品としては、従来、操作軸にスプライン結合させた回転体に摺動子を取り付け、この摺動子を所定の回路パターンに摺接させると共に、操作軸の軸線方向端部と対向する位置に可動接点部材を配置させ、この可動接点部材を固定接点に接離させるという構成のものが広く知られている。 [0003] The composite operation type electric component of this kind, conventionally, attached to slider to the rotating body splined allowed the operation shaft, the sliding contact of the slider to a predetermined circuit pattern, the operating shaft a position facing the axial end is disposed a movable contact member, is widely known that the structure of contacting and separating the movable contact member with the fixed contact. 回転体には断面形状が例えば小判形の中心孔が設けられており、 The rotating body is provided with a center hole of the cross-sectional shape for example oval,
この中心孔に略同形の操作軸を挿通することにより、操作軸を回転させると回転体が一体的に回転するようになっている。 By inserting the operating shaft of substantially the same shape in the central hole, the rotating body is rotated integrally with the rotating operating shaft. その結果、摺動子が所定の回路パターン(接点パターンや抵抗パターン)に対して摺動し、操作軸の回転角度や回転方向に応じたパルス信号や抵抗値が出力されるようになっている。 As a result, the slider is adapted to slide with respect to a predetermined circuit pattern (contact pattern and the resistor pattern), the pulse signal and the resistance value corresponding to the rotation angle and the rotation direction of the operating shaft is output . また、操作軸を軸線方向へ押し込んだ場合、スプライン結合されている回転体は軸線方向に移動しないが、可動接点部材が操作軸の軸線方向端部に押し込まれて弾性変形するので、操作軸を所定ストローク押し込むことにより可動接点部材を固定接点に接触させることができ、その結果、スイッチの切り換え信号(オン/オフ信号)が出力されるようになっている。 In addition, when pushed in operation shaft in the axial direction, since the rotating body is spline-coupled does not move in the axial direction, the movable contact member is pushed into the axial end of the operating shaft is elastically deformed, the operating shaft It can be brought into contact with the fixed contact the movable contact member by pushing a predetermined stroke, as a result, so that the switch switching signal (oN / oFF signal) is output. 【0004】 【発明が解決しようとする課題】上述した従来の複合操作型電気部品においては、操作軸やケースを共通化した回転機構部と押圧機構部とが実現されているので、操作形態の異なる2種類の電気部品を使用する場合に比べて部品点数を削減できるが、それでもケース内に操作軸、 [0004] In the [0008] conventional composite electric component as described above, since the operation shaft and the rotation mechanism section case made common and the pressing mechanism is implemented, the control mode of Although the number of parts can be reduced as compared with the case of using two different electrical components, but still operating shaft in the case,
摺動子付きの回転体、可動接点部材、戻しばね等を組み込まねばならないので組立て作業が煩雑であり、近年強まっているコストダウンの要望に応えるためには部品点数をさらに削減して構成を簡素化する必要がある。 Rotating body with the slider, the movable contact member, the assembling work since must incorporate a return spring or the like is complicated, simplify the further reduction to configure the number of components in order to meet the demands of cost reduction is growing in recent years there is a need to be of. また、かかる従来の複合操作型電気部品では、回転機構部用の接点パターンの形成面と押圧機構部用の固定接点の形成面とを高さ方向にある程度離しておかなければならないので、複合操作型電気部品全体の高さ寸法が増大しやすいという不具合もあった。 Further, since such a conventional composite electric component, it must be kept a certain distance and the formation surface of the fixed contact for forming surface and the pressing mechanism of the contact pattern for the rotary mechanism in the height direction, combined operation type electrical components overall height dimension there is also a problem that tends to increase. 【0005】本発明は、このような従来技術の実情に鑑みてなされたもので、その目的は、部品点数を削減できて高さ寸法も低減させやすい複合操作型電気部品を提供することにある。 [0005] The present invention has such has been made in view of the circumstances of prior art, and an object thereof is to provide a composite electric component tends height dimension can reduce the number of parts is reduced . 【0006】 【課題を解決するための手段】上述した目的を達成するために、本発明は、回転可能かつ軸線方向に移動可能な操作軸と、この操作軸にスプライン結合されて一体的に回転可能な回転体と、この回転体に保持された金属接点板と、この金属接点板に対向配置されて回転機構部用パターンおよび押圧機構部用パターンを有する回路パターンとを備え、前記金属接点板に、前記回転機構部用パターン上を摺動可能な摺動子片と、前記押圧機構部用パターンに接離可能な可動接触片とを設け、前記操作軸の軸線方向奥側の端部を前記可動接触片に対向させる構成にした。 [0006] To achieve the Means for Solving the Problems] above object, the present invention is rotatably and an operating shaft movable in the axial direction, rotates together is spline coupled to the operating shaft a rotating body that can, and a metal contact plate which is held on the rotary member, and a circuit pattern having disposed opposite the rotation mechanism section pattern and the pressing mechanism part pattern on the metal contact plate, the metal contact plate to, said rotation mechanism section pattern on a slidable a sliding piece is provided with a detachably movable contact piece in the pressing mechanism part pattern, the ends of the axial inner side of the operation shaft It was configured to be opposed to the movable contact piece. 【0007】このように構成された複合操作型電気部品では、1枚の金属接点板に、押圧機構部の可動接点部材として機能する可動接触片と、回転機構部用の摺動子片とが設けてあるので、部品点数を削減できて組立て性も向上する。 [0007] In thus configured composite operation type electric component, on one of the metal contact plate, and a movable contact piece that acts as a movable contact member of the pressing mechanism, and a sliding piece for a rotating mechanism since is provided, also improved assembling property can reduce the number of components. また、こうして1枚の金属接点板に可動接触片と摺動子片とが設けてある関係上、押圧機構部用パターンと回転機構部用パターンとを同一面に形成することができ、高さ寸法の低減(低背化)が図りやすいだけでなく、高精度な回路パターンを容易に形成できるという利点もある。 Moreover, in this way it is possible to form one metal contact plate to the movable contact piece and sliding piece and is on the relationship between is provided, a pressing mechanism part pattern and the rotation mechanism section pattern on the same surface, the height reduced dimensions as well (low-profile) is easily be made, there is an advantage that a highly accurate circuit pattern can be easily formed. 【0008】上記の構成において、前記可動接触片が金属接点板に片持ち梁状に形成された弾性金属片で、この可動接触片の自由端部に押圧機構部用パターンと接離可能な可動接点を設けることが好ましい。 [0008] In the above configuration, the moving contact piece of a resilient metal piece formed in a cantilever shape on a metal contact plate, the free end portion patterning separable for pressing mechanism to a movable of the movable contact piece it is preferable to provide a contact point. この場合、前記可動接触片が弾性金属片の中央に開口を有する環状金属片であれば、可動接触片が開口を有さない舌状に形成されている場合に比べて弾性変形しやすくなるので、長期に亘ってへたりにくい可動接触片となって複合操作型電気部品の長寿命化が図れる。 In this case, if the annular metal piece the moving contact piece having an opening in the center of the elastic metal strip, so easily elastically deformed as compared with the case where the movable contact piece is formed on the tongue without the opening , the life of the composite electric component become have enough hard movable contact piece to a long term can be achieved. 【0009】また、上記の構成において、操作軸の軸線方向奥側の端部に可動接触片を面接触状態で駆動する駆動部が突設してあれば、多少の寸法誤差があったとしても、押圧操作時に可動接触片を不所望な形状に弾性変形させてしまう危険性が少なくなるので好ましい。 Further, in the above-described structure, if the driving unit for driving the movable contact piece on the end of the axial inner side of the operation shaft in a surface contact is protruded, even if some dimensional error preferred because the risk that the movable contact piece thus is elastically deformed in an undesired shape is reduced during the pressing operation. この場合、駆動部が可動接触片の自由端よりも基端に近い部分と面接触するように設定しておけば、駆動部に押し込まれる可動接触片は、その自由端部に設けた接点が押圧機構部用パターンに当接した後も弾性変形しやすくなるので、押圧操作時に可動接触片を無理なく撓めることができ、可動接触片のへたりを防止する効果が高まる。 In this case, the drive unit by setting such that the contact portion and the plane closer to the base end than the free end of the movable contact piece, the movable contact piece to be pushed into the drive unit, the contact is provided at its free end since the pressing mechanism part pattern easily elastically deformed even after the contact with the movable contact piece can deflect without difficulty during the pressing operation increases the effect of preventing the sag of the movable contact piece. 【0010】

図3に示すように、回路基板2のうち金属接点板8の真下に配置される部分の上面には、回転機構部用の複数の帯状接点パターン10と押圧機構部用の固定接点11とが形成されている。 As shown in FIG. 3, on the upper surface of the portion disposed beneath the metal contact plate 8 of the circuit board 2, a plurality of strip-shaped contact patterns 10 and the fixed contact 11 for the pressing mechanism part of the rotary mechanism portion It is formed. これら帯状接点パターン10群は固定接点11を包囲するように互いに位相をずらして同心円状に配置されており、また、回路基板2の一側部には各帯状接点パターン10や固定接点11から引き廻した端子12群が形成されている。 These strip-shaped contact pattern 10 group are arranged out of phase with each other so as to surround the fixed contact 11 concentrically, also drawn on one side of the circuit board 2 from the respective strip-like contact pattern 10 and the fixed contact 11 turn terminal 12 group is formed the. 枠板3はブリキ等の金属板を折曲加工したもので、回路基板2をケース1に一体化させている。 The frame plate 3 is obtained by bending process of metal plate tin or the like, and are integrated circuit board 2 to the case 1. 【0013】操作軸4は亜鉛ダイキャスト等の金属材料からなり、ケース1に回転可能かつ軸線方向に移動可能な状態で保持されている。 [0013] operating shaft 4 is made of a metal material such as zinc die casting, it is held in a movable state in rotatable and axially to the case 1. 図1と図4に示すように、操作軸4の底部には、小判形の鍔部4aと、この鍔部4a As shown in FIGS. 1 and 4, the bottom portion of the operating shaft 4, the flange portion 4a of the oval, the flange portion 4a
の内周側で下方に臨出する環状の凹溝4bと、この凹溝4bに包囲されて下方へ突出する板状の駆動部4cとが形成されている。 And the groove 4b on the inner peripheral side of the annular shape 臨出 below, a plate-like drive portion 4c projecting downward is surrounded by the groove 4b is formed. なお、駆動部4cは、操作軸4の軸心から僅かにずれた位置に突設してある。 The drive unit 4c, are projecting from the shaft center slightly offset position of the operating shaft 4. 戻しばね5は凹溝4b内に組み込まれたコイルばねで、上下動が可能な操作軸4と上下動が規制されている回転体6との間に圧縮状態で介設されており、操作軸4が下方へ押し込まれるとこれを上方へ弾性付勢する。 Return spring 5 is a coil spring embedded in the groove 4b, it is interposed in a compressed state between the rotary member 6 which moves up and down is capable operating shaft 4 and the vertical movement is restricted, the operation shaft 4 is elastically bias it when pushed into the bottom to the top. 【0014】回転体6は合成樹脂で成形されており、その中央には駆動部4cを挿通させる貫通孔6bが形成されている。 [0014] Rotation member 6 is molded of synthetic resin, in the center is formed a through hole 6b for inserting the drive unit 4c is. 図1と図5に示すように、回転体6には貫通孔6bの周囲に鍔部4aと略同形の小判形の凹所6cが形成されており、この凹所6c内に鍔部4aを挿入することによって、回転体6は操作軸4にスプライン結合されている。 As shown in FIGS. 1 and 5, the rotary body 6 is around the recess 6c of the oval-shaped flange portion 4a and substantially the same shape in the form of a through-hole 6b, the flange portion 4a in the recess 6c by inserting, rotating body 6 is splined to the operating shaft 4. また、回転体6の上面の外周部には、多数のクリック突起6aが一定の間隔で周方向に沿って列設されている。 Further, the outer peripheral portion of the upper surface of the rotating body 6, a number of clicks projections 6a are columns set along the circumferential direction at regular intervals. クリックばね7はリン青銅等の弾性に富む金属板からなり、ケース1の内部に保持されている。 Click spring 7 is made of a metal plate highly elastic, such as phosphor bronze, it is held inside the case 1. そして、このクリックばね7の弾性片7aが回転体6の上面部に弾接しているので、回転体6が回転すると、それに伴って弾性片7aがクリック突起6aに係脱してクリック感を生起する。 Then, the elastic piece 7a of the click spring 7 is elastic contact with the upper surface of the rotating body 6, when the rotary body 6 rotates, the elastic piece 7a arising click feeling disengaged from the click protrusions 6a with it . 【0015】金属接点板8はリン青銅等の弾性に富む金属薄板を図1と図6に示すような形状にプレス加工したものであり、回転体6の下面に熱がしめ等によって固定されている。 The metal contact plate 8 is obtained by pressing a metal sheet rich elasticity such as phosphor bronze into a shape as shown in FIGS. 1 and 6, are secured by heat staking or the like to the lower surface of the rotary member 6 there. この金属接点板8には、回路基板2の帯状接点パターン10群と摺動可能な複数の摺動子片13 The metal contact plate 8, strip contact pattern 10 group of the circuit board 2 and the slidable plurality of sliding piece 13
と、回路基板2の固定接点11と接離可能な可動接点1 When the fixed contacts 11 of the circuit board 2 and detachably movable contact 1
4aを有する略C字形の可動接触片14とが形成されており(図3参照)、可動接触片14は操作軸4の駆動部4cと対向している(図2参照)。 A movable contact piece 14 of substantially C-shaped having a 4a is formed (see FIG. 3), the movable contact piece 14 faces the drive portion 4c of the operating shaft 4 (see FIG. 2). この可動接触片14 The movable contact piece 14
は金属接点板8の中央に穿設された開口8aに沿って延びる環状金属片であり、その両端を基端部として金属接点板8に片持ち梁状に形成されている。 Is annular metal strips extending along the opening 8a bored in the center of the metal contact plate 8 is formed in a cantilevered metal contact plate 8 both ends as proximal end. なお、操作軸4 In addition, the operating shaft 4
の駆動部4cは可動接触片14の自由端よりも基端に近い部分A(図6参照)の真上に位置しており、操作軸4 The drive portion 4c is located directly above the portion close to the base end than the free end of the movable contact piece 14 A (see FIG. 6), the operating shaft 4
が下方へ押し込まれると、その駆動部4cが該部分Aに面接触して可動接触片14を弾性変形させるようになっている。 There When pushed downward, has a movable contact piece 14 a drive unit 4c is in surface contact with the partial A so as to be elastically deformed. 【0016】このように構成された複合操作型電気部品において、操作者が手指で操作軸4を回転操作すと、回転体6が操作軸4と一体的に回転して、金属接点板8の各摺動子片13が回路基板2の帯状接点パターン10上を摺動するので、操作軸4の回転角度や回転方向に応じたパルス信号が出力される。 [0016] In the configuration composite electric component in this manner, the operator when to rotate the operating shaft 4 with a finger, the rotating body 6 and rotates integrally with the operating shaft 4, the metal contact plate 8 each sliding piece 13 slides on the belt-like contact pattern 10 of the circuit board 2, a pulse signal corresponding to the rotation angle and the rotation direction of the operating shaft 4 is outputted. このとき、回転体6の回転に伴ってクリックばね7の弾性片7aがクリック突起6 At this time, click elastic piece 7a of the click spring 7 with the rotation of the rotary member 6 projection 6
aと係脱するので、操作者はクリック感によって回転量を把握することが可能となる。 Since a and disengaged, the operator so that it is possible to determine the amount of rotation by clicking sensation. つまり、この複合操作型電気部品は、操作軸4を回転操作することにより、ロータリエンコーダとして動作させることができる。 That is, the composite electric component, by rotating the operating shaft 4 can be operated as a rotary encoder. 【0017】一方、操作者が操作軸4を軸線方向へ所定ストローク押し込んだ場合には、操作軸4にスプライン結合されている回転体6は軸線方向へ移動しないが、操作軸4の駆動部4cが金属接点板8の可動接触片14を押し撓めるため、図2に示すように、可動接触片14の可動接点14aが回路基板2の固定接点11に接触し、 Meanwhile, when the operator pushed predetermined stroke operating shaft 4 in the axial direction is the rotary member 6 which is spline-coupled to the operating shaft 4 is not moved in the axial direction, the operating shaft 4 driving unit 4c There for flex pressing the movable contact piece 14 of the metal contact plate 8, as shown in FIG. 2, the movable contact 14a of the movable contact piece 14 comes into contact with the fixed contact 11 of the circuit board 2,
オン/オフの切り換え信号が出力されて例えばオフ状態からオン状態になる。 On / from the switching signal is output for example off off turned on. また、かかるオン状態で押し込み操作力が除去されると、戻しばね5が操作軸4を図1に示す位置まで押し上げるので、可動接点14aは固定接点11から離れてオフ状態に戻る。 Further, when the operation force indentation in such ON state is removed, return the spring 5 pushes the operating shaft 4 to the position shown in FIG. 1, the movable contact 14a returns to the OFF state away from the fixed contact 11. つまり、この複合操作型電気部品は、操作軸4を押圧操作することにより、 That is, the composite electric component, by pressing the operating shaft 4,
プッシュスイッチとして動作させることができる。 It can be operated as a push switch. 【0018】このように本実施形態例に係る複合操作型電気部品は、回転体6に保持された1枚の金属接点板8 [0018] Thus the composite operation type electric component according to the present embodiment is held by the rotary member 6 one metal contact plate 8
に、プッシュスイッチ用の可動接点部材である可動接触片14と、ロータリエンコーダ用の摺動子片13群とが設けてあるので、部品点数を削減することができると共に、構成が簡素で組立て性も良好となる。 To a movable contact piece 14 is a movable contact member for the push switch, since the sliding piece 13 group for a rotary encoder is provided, it is possible to reduce the number of parts, assembling of a configuration simpler also it will be good. また、これら可動接触片14と摺動子片13群を金属接点板8の中央部と外周部に振り分けてあることから、回路基板2上の同一面にプッシュスイッチ用の固定接点11とロータリエンコーダ用の帯状接点パターン10群とを配設することができ、それゆえ全体の高さ寸法を低減できるのみならず、両パターン10,11を高精度かつ容易に形成することができる。 The central part and the fact that is distributed to the outer peripheral portion, the fixed contact 11 for the push switch on the same plane on the circuit board 2 and the rotary encoder of these movable contact piece 14 and the sliding piece 13 group metal contact plate 8 can be disposed and belt-shaped contact pattern 10 group use, not only can reduce the height of the whole therefore, it is possible to form the both patterns 10, 11 easily and highly accurately. 【0019】また、本実施形態例においては、プッシュスイッチ用の可動接触片14が、開口8aに沿って延びて両端を基端となした環状金属片なので弾性変形しやすく、それゆえ弾性変形を繰り返しても可動接触片14はへたりを起こしにくい。 Further, in the present embodiment, the movable contact piece 14 for the push switch, since the annular metal pieces without a proximal the ends extending along the opening 8a easily elastically deformed, hence elastic deformation Repeat the movable contact piece 14 is less prone to sag. しかも、可動接触片14を押し込む操作軸4の下端部が板状の駆動部4cとなっており、この駆動部4cは面接触状態で可動接触片14を押圧駆動するので、多少の寸法誤差があったとしても、押圧操作時に可動接触片14を不所望な形状に弾性変形させてしまう危険性は少ない。 Moreover, the lower end of the operating shaft 4 for pushing the movable contact piece 14 has a plate-like drive portion 4c, since the drive unit 4c to press drives the movable contact piece 14 in a surface contact state, some dimensional error even the risk of the movable contact piece 14 thus is elastically deformed in an undesired shape during the pressing operation is small. さらに、駆動部4cが可動接触片14の自由端よりも基端に近い部分と面接触するように設定してあるので、駆動部4cに押し込まれた可動接触片14は、可動接点14aが固定接点11に当接した後も弾性変形しやすく、押圧操作時に可動接触片1 Furthermore, since the drive portion 4c has been set to partial surface contact closer to the base end than the free end of the movable contact piece 14, the movable contact piece 14 pushed into the drive unit 4c, the movable contact 14a fixed also easily elastically deformed after contact with the contact 11, the movable contact piece 1 during the pressing operation
4を無理なく撓めることができる。 4 it is possible to deflect without difficulty. したがって、この複合操作型電気部品は、可動接触片14が長期に亘って動作不良を起こしにくく、高信頼性が維持しやすくなっている。 Therefore, the composite operation type electrical component, the movable contact piece 14 is less likely to cause malfunction over a long term, high reliability easily maintained. 【0020】なお、上述した実施形態例では、回転操作時にエンコーダとして動作し押圧操作時にプッシュスイッチとして動作する複合操作型電気部品について説明しているが、本発明はこれに限定されるものではない。 [0020] In the embodiment example described above, has been described composite electric component which operates as a push switch when operating as an encoder pressed during rotational operation, the present invention is not limited thereto . 例えば、金属接点板8の摺動子片13を回路基板2上の抵抗パターンに摺接させることにより、回転操作時に可変抵抗器として動作するように構成してもよい。 For example, by sliding the sliding piece 13 of the metal contact plate 8 to the resistance pattern on the circuit board 2 may be configured to operate as a variable resistor at the time of rotation operation. また、可動接触片14のばね性を高めておくことにより、戻しばね5を省略した構成にすることも可能である。 Furthermore, by previously increasing the spring property of the movable contact piece 14, it is also possible to adopt a configuration omitting the return spring 5. 【0021】 【発明の効果】本発明は、以上説明したような形態で実施され、以下に記載されるような効果を奏する。 [0021] The present invention is implemented in the form as described above, an effect as described below. 【0022】操作軸にスプライン結合された回転体が1 The splined rotational member to the operation shaft 1
枚の金属接点板を保持し、この金属接点板に、押圧機構部の可動接点部材として機能する可動接触片と、回転機構部用の摺動子片とが設けてある複合操作型電気部品なので、部品点数を削減できて組立て性も向上する。 Holding the sheet of metal contact plate, the metal contact plate, and a movable contact piece that acts as a movable contact member of the pressing mechanism, the composite since the operation type electrical component and sliding piece for a rotating mechanism is provided is also improved assembling property can reduce the number of components. また、回路パターンの回転機構部用パターンと押圧機構部用パターンを同一面に形成することができるので、電気部品全体の高さ寸法を低減できると共に、高精度な回路パターンを容易に形成できる。 Further, it is possible to form a rotation mechanism portion pattern and the pressing mechanism part pattern of the circuit pattern on the same surface, it is possible to reduce the height of the entire electrical part can be easily formed with high precision circuit pattern.
