図13は従来の回転操作型エンコーダの断面図、図14は同操作軸の組み合わせ作業を説明する図であり、同図において、1は金属棒からなる操作軸で、上部が操作部1E、その下方が中間円形部1A、そのリング状溝部1Dから下方は水平断面が小判形の作動部1Bとなっている。そして、上記中間円形部1A下端にはリング状溝部1Dが設けられている。   FIG. 13 is a cross-sectional view of a conventional rotary operation type encoder, and FIG. 14 is a view for explaining the combination operation of the operation shafts. In FIG. The lower portion is an intermediate circular portion 1A, and the lower portion from the ring-shaped groove portion 1D is an operating portion 1B having an oval horizontal cross section. A ring-shaped groove 1D is provided at the lower end of the intermediate circular portion 1A.

2は、軸受であり、矩形の平板部2Cの中央部分が円形状に上方に突出した円形突部2Dの内側が下方開口の円形開口部2Aとなり、その突出した上面中央には小円形孔2Bが設けられている。   Reference numeral 2 denotes a bearing, and a circular projecting portion 2D in which a central portion of a rectangular flat plate portion 2C projects upward in a circular shape is a circular opening 2A having a lower opening, and a small circular hole 2B is formed in the center of the projecting upper surface. Is provided.

そして、上記操作軸1の操作部1E下方が軸受2の小円形孔2Bに上方から挿通されて、軸受2の小円形孔2Bの下側に突出した中間円形部1A下端のリング状溝部1D内に、C形リング3が取り付けられて操作軸1の抜け止め部が構成されており、操作軸1は回転操作及び上下操作が可能なようにその中間円形部1Aが小円形孔2Bで嵌合保持されている。   The lower part of the operating shaft 1E of the operating shaft 1 is inserted into the small circular hole 2B of the bearing 2 from above, and protrudes below the small circular hole 2B of the bearing 2 in the ring-shaped groove 1D at the lower end of the intermediate circular part 1A. Further, a C-shaped ring 3 is attached to form a retaining portion of the operation shaft 1, and the intermediate circular portion 1A is fitted in the small circular hole 2B so that the operation shaft 1 can be rotated and vertically operated. Is retained.

そして、上記軸受2の平板部2C下面には、円形開口部2Aと同心となるように弾性金属薄板からなるリング状の押えバネ4が装着されており、その押えバネ4は成形樹脂製の回転体5上面との間で挟み込まれている。当該構成部分で回転体5が回転操作された時の回転トルクを発生させている。   A ring-shaped presser spring 4 made of an elastic metal thin plate is mounted on the lower surface of the flat plate portion 2C of the bearing 2 so as to be concentric with the circular opening 2A. The presser spring 4 is a rotation made of molded resin. It is sandwiched between the upper surface of the body 5. Rotational torque is generated when the rotating body 5 is rotated by the component.

上記回転体5は、下面に導電性金属からなる平面接点板6をインサート成形して固定した円板部5Aと、その中心に垂直に突設された円筒部5Bからなり、この円筒部5Bが上記軸受2の円形開口部2Aに下方から挿入されて、回転運動が可能なようにその外周を嵌合保持されている。そして、その円筒部5Bの中心に設けられ、上記操作軸1の作動部1Bの水平断面と同形状の小判形の貫通孔5Cに、上記操作軸1の作動部1Bが、回転運動は伝達されるが上下動作は伝わらないように挿通されている。   The rotating body 5 includes a disc portion 5A in which a flat contact plate 6 made of a conductive metal is insert-molded and fixed on the lower surface, and a cylindrical portion 5B projecting perpendicularly to the center thereof. It is inserted into the circular opening 2A of the bearing 2 from below, and its outer periphery is fitted and held so that it can rotate. Then, the rotational movement of the operating portion 1B of the operating shaft 1 is transmitted to an oval through hole 5C having the same shape as the horizontal section of the operating portion 1B of the operating shaft 1 provided at the center of the cylindrical portion 5B. However, it is inserted so that the vertical movement is not transmitted.

回転体5の円板部5Aの下面に固定された平面接点板6は、放射状に孔があけられて櫛歯状にその表面が露出している。一方、その下方位置には、導電性の弾性金属薄板からなる複数の弾性脚8を絶縁樹脂でインサート成形固定した固定基板7が所定の間隔をあけて配されており、この固定基板7から伸ばされた複数の弾性脚8の先端の弾性接点9が、対向する上記平面接点板6が櫛歯状で露出した円板部5A下面に各々弾接している。また、上記固定基板7は上方開口箱型に形成されており、上記回転体5の円板部5Aは、固定基板7と軸受2の平板部2C下面とで構成される空間内に内包されている。   The flat contact plate 6 fixed to the lower surface of the disk portion 5A of the rotator 5 is radially perforated and has a comb-like surface exposed. On the other hand, a fixed substrate 7 in which a plurality of elastic legs 8 made of a conductive elastic metal thin plate are insert-molded and fixed with an insulating resin is arranged at a predetermined interval at a lower position. The elastic contacts 9 at the tips of the plurality of elastic legs 8 are in elastic contact with the lower surface of the disk portion 5A where the opposing flat contact plates 6 are exposed in a comb shape. The fixed substrate 7 is formed in an upper opening box shape, and the disk portion 5A of the rotating body 5 is enclosed in a space formed by the fixed substrate 7 and the lower surface of the flat plate portion 2C of the bearing 2. Yes.

さらに固定基板7の下方にはスイッチ基板10が配置され、そのスイッチ基板10の上面中央の凹部10A内には、上記操作軸1の軸心と同心位置に中央固定接点11Aおよびその外周位置に外周固定接点11Bがインサート成形により固定されており、外周固定接点11B上には弾性金属薄板製のドーム状可動接点12の外周下端が載せられている。そして、ドーム状可動接点12の上部に略円板状のプッシュ板14が載せられて押圧スイッチ部13が構成されていると共に、そのプッシュ板14の上方部分は、固定基板7の中孔を介して上方に突出しており、その上端面に上記操作軸1の下端部1Cが当接している。この状態において、操作軸1のリング状溝部1Dに挿入されたC形リング3は、軸受2の円形開口部2Aを構成する天面に当接している。   Further, a switch board 10 is disposed below the fixed board 7, and a central fixed contact 11 </ b> A is concentric with the axis of the operation shaft 1 in the recess 10 </ b> A at the center of the upper surface of the switch board 10, and an outer periphery is provided at the outer peripheral position. The fixed contact 11B is fixed by insert molding, and the lower end of the outer periphery of the dome-shaped movable contact 12 made of an elastic metal thin plate is placed on the outer peripheral fixed contact 11B. The push switch portion 13 is configured by placing a substantially disc-shaped push plate 14 on the upper portion of the dome-shaped movable contact 12, and an upper portion of the push plate 14 is interposed through a hole in the fixed substrate 7. The lower end portion 1C of the operation shaft 1 is in contact with the upper end surface thereof. In this state, the C-shaped ring 3 inserted into the ring-shaped groove 1D of the operating shaft 1 is in contact with the top surface constituting the circular opening 2A of the bearing 2.

そして、15は、コの字形の取付金具であり、軸受2の円形突部2Dをその中央孔から上方に突出させるようにして、軸受2の上方側から、軸受2、固定基板7およびスイッチ基板10を重ね合わせて脚部15Aで挟み込み、スイッチ基板10の底面で脚部15A先端を折り曲げることにより全体が連結固定されて回転操作型エンコーダとして構成されている。   Reference numeral 15 denotes a U-shaped mounting bracket which projects the circular protrusion 2D of the bearing 2 upward from its central hole, and from the upper side of the bearing 2, the bearing 2, the fixed substrate 7 and the switch substrate. 10 are overlapped and sandwiched between the leg portions 15A, and the tip of the leg portion 15A is bent at the bottom surface of the switch substrate 10 so that the whole is connected and fixed to constitute a rotary operation type encoder.

次にこの回転操作型エンコーダの動作について説明すると、まず操作軸1の操作部1Eを回転操作することにより、操作軸1の作動部1Bが嵌合された貫通孔5Cを介して回転体5が回転させられ、平面接点板6が櫛歯状で露出した円板部5A下面に対し複数の弾性接点9が各々摺動接触して弾性脚部8に接続された端子16からパルス信号が得られる。この回転操作時には操作軸1は上下方向には動かず、押圧スイッチ部13は動作しない。   Next, the operation of the rotary operation type encoder will be described. First, by rotating the operating portion 1E of the operating shaft 1, the rotating body 5 is moved through the through hole 5C into which the operating portion 1B of the operating shaft 1 is fitted. A plurality of elastic contacts 9 are brought into sliding contact with the lower surface of the disk portion 5A where the planar contact plate 6 is exposed in a comb-teeth shape, and a pulse signal is obtained from the terminal 16 connected to the elastic leg portion 8. . During this rotation operation, the operation shaft 1 does not move in the vertical direction, and the push switch unit 13 does not operate.

次に、操作軸1の操作部1Eに押し力を加えて下方に押下すると、その下端部1Cがプッシュ板14を介してドーム状可動接点12を押すことによって押圧スイッチ部13がオンし、操作部1Eに加えた押し力を解除すると、ドーム状可動接点12が自己復元して押圧スイッチ部13がオフ状態の元の図13に示す状態に戻る。   Next, when a pressing force is applied to the operating portion 1E of the operating shaft 1 and pressed downward, the lower end portion 1C pushes the dome-shaped movable contact 12 via the push plate 14, whereby the pressing switch portion 13 is turned on. When the pressing force applied to the portion 1E is released, the dome-shaped movable contact 12 is self-restored and the pressing switch portion 13 returns to the original state shown in FIG.

この操作軸1の押圧操作時に、回転体5は下方へは動かず、勿論回転運動もしないので、押圧スイッチ部13のみが動作するものであった。   During the pressing operation of the operating shaft 1, the rotating body 5 does not move downward and of course does not rotate, so that only the pressing switch portion 13 operates.

しかしながら、上記従来の回転操作型電子部品(回転操作型エンコーダ)においては、図14の操作軸にC形リングを取り付ける図に示すように、操作軸1の下端部1C側からC形リング3を広げて作動部1Bに嵌め、その作動部1Bを通過させて、上部のリング状溝部1Dまで移動させてリング状溝部1Dに嵌め込んで操作軸1の抜け止め部を形成するもののため、この方式ではC形リング3を必要とすると共に、その嵌め込み作業は、軸受2の円形開口部2A内で行う作業であり、嵌め込み状態を確認するのが非常に難しく、作業性も悪いため、作業工数がかかるという課題を有していた。   However, in the conventional rotary operation type electronic component (rotation operation type encoder), as shown in the figure in which the C-shaped ring is attached to the operation shaft in FIG. This method is used to form the retaining portion of the operating shaft 1 by expanding and fitting into the operating portion 1B, passing through the operating portion 1B, moving to the upper ring-shaped groove 1D and fitting into the ring-shaped groove 1D. Then, the C-shaped ring 3 is required, and the fitting operation is performed in the circular opening 2A of the bearing 2, and it is very difficult to check the fitting state and the workability is also poor. It had the subject that it took.

本発明は、このような従来の課題を解決するものであり、操作軸の抜け止めを確実に行うことができて、組立作業性が良く、作業工数も低減できる回転操作型電子部品を提供することを目的とする。   The present invention solves such a conventional problem, and provides a rotary operation type electronic component that can reliably prevent an operation shaft from being removed, has good assembly workability, and can reduce work man-hours. For the purpose.

上記目的を達成するために本発明は、以下の構成を有するものである。   In order to achieve the above object, the present invention has the following configuration.

本発明の請求項1に記載の発明は、回転電気部材を備えた回転体と、この回転体が回転されて上記回転電気部材との接触により電気信号を生じる固定電気部材を備えた基体と、この基体の上方に固定された軸受と、この軸受で回転可能に保持され、上記回転体を回転操作する操作軸とを備え、上記操作軸は、第一段部の上方が操作部で、その第一段部の下方が棒状の中間部そしてさらにその中間部下端が第二段部を境に作動部としてなり、この作動部は水平断面が略矩形で、その略矩形の長手方向の寸法が上記中間部の外形寸法より大きな寸法になされており、上記回転体は、中心に上記操作軸の第一段部より下方が挿通可能なようにその投影面積に合わせた形状で、上記操作軸の中間部の長さより短い長さの貫通孔を有し、上記略矩形の作動部の長手方向に直交する方向に上記作動部が嵌り込む下方開口の窪みが下面に設けられており、上記回転体の貫通孔に挿通された上記操作軸は、その作動部が上記窪み内に位置されて両者の係合により上記回転体を回転操作可能となし、かつ上記第二段部が上記窪みの天面に当接係止して上方への抜け止めがなされた構成としたことを特徴とする回転操作型電子部品としたものである。   The invention according to claim 1 of the present invention includes a rotating body provided with a rotating electric member, and a base body provided with a fixed electric member that generates an electric signal by contact with the rotating electric member by rotating the rotating body, A bearing fixed above the base; and an operating shaft rotatably held by the bearing and for rotating the rotating body. The operating shaft is an operating portion above the first step portion. The lower part of the first step part is a rod-shaped intermediate part, and the lower end of the intermediate part is an action part with the second step part as a boundary. The action part has a substantially rectangular horizontal section, and the length of the substantially rectangular longitudinal direction is The rotating body has a size larger than the outer dimension of the intermediate portion, and the rotating body has a shape that matches the projected area so that the lower part of the operating shaft can be inserted below the first step portion of the operating shaft. It has a through hole with a length shorter than the length of the middle part, A depression of a lower opening in which the operating part fits in a direction perpendicular to the longitudinal direction of the part is provided on the lower surface, and the operating shaft inserted through the through hole of the rotating body has the operating part in the depression. It is positioned so that the rotating body can be rotated by engaging the both, and the second stepped portion is brought into contact with and locked to the top surface of the recess to prevent the upper portion from coming off. The rotating operation type electronic component is characterized.

この構成により、操作軸の作動部を回転体の貫通孔に挿通させた後、操作軸をその軸線中心を回転中心として90°回転させてから作動部が回転体の窪みに嵌り込むまで上方向に引き上げるのみで操作軸が固定され、操作軸の上方への抜け止めがなされると共に、操作軸の回転運動を回転体に伝えることもできるため、簡単な構成で確実な操作軸の抜け止め機構を備えたものにでき、組み立て作業の効率化および作業工数の低減を図ることができるという作用を有する。   With this configuration, after the operating portion of the operating shaft is inserted into the through hole of the rotating body, the operating shaft is rotated 90 ° about the axis center of the operating shaft and then the operating portion is upward until the operating portion is fitted into the recess of the rotating body. The operating shaft is fixed simply by pulling it up to prevent the operating shaft from coming off upwards, and the rotational movement of the operating shaft can be transmitted to the rotating body.

請求項2に記載の発明は、請求項1記載の発明において、操作軸の下方に押圧スイッチが設けられ、上記操作軸の作動部と回転体の窪みとの上下方向の重なり寸法が上記押圧スイッチの操作距離より長く設定されて、上記操作軸で上記押圧スイッチを操作可能に上下動作可能とされているものである。   According to a second aspect of the present invention, in the first aspect of the invention, a pressure switch is provided below the operation shaft, and the vertical overlap dimension between the operating portion of the operation shaft and the recess of the rotating body is the pressure switch. The operation distance is set to be longer than the operation distance, and the push switch can be operated up and down by the operation shaft.

これにより、操作軸の回転運動を回転体に伝えると共に、操作軸の上下操作に際しては、回転体にその運動を伝えることなく押圧スイッチが操作可能なものにでき、押圧スイッチを備えた回転操作型電子部品を容易に構成できるという作用を有する。   As a result, the rotary motion of the operating shaft is transmitted to the rotating body, and when the operating shaft is operated up and down, the push switch can be operated without transmitting the motion to the rotating body. The electronic component can be easily configured.

以上のように本発明によれば、C形リングが不要でその取り付け工程も不要としながら、操作軸の確実な抜け止めの確保ができると共に、組立作業工数の低減が図れる回転操作型電子部品を提供することができるという有利な効果が得られる。   As described above, according to the present invention, there is provided a rotary operation type electronic component which can secure a reliable prevention of the operation shaft and reduce the number of assembling operations while eliminating the need for a C-shaped ring and an attaching process thereof. The advantageous effect that it can be provided is obtained.

以下、本発明の実施の形態について、図1〜図12を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS.

なお、従来の技術の項で説明した構成と同一構成の部分には同一符号を付して、詳細な説明を簡略化する。   In addition, the same code | symbol is attached | subjected to the part of the structure same as the structure demonstrated in the term of the prior art, and detailed description is simplified.

(Embodiment)
FIG. 1 is a cross-sectional view of a rotary operation type encoder according to an embodiment of the present invention, and FIG. 2 is an external perspective view of an operation shaft as the main part.

同図において、21は金属棒からなる操作軸であり、大径の略円柱状に形成された上方の操作部21D下方に中間部21Aを備え、さらにその中間部21A下方に作動部21Bを備えている。   In the figure, reference numeral 21 denotes an operating shaft made of a metal rod, which is provided with an intermediate portion 21A below an upper operating portion 21D formed in a large-diameter substantially cylindrical shape, and further provided with an operating portion 21B below the intermediate portion 21A. ing.

そして、操作部21D下端の第一段部21Eの下方に設けられた中間部21Aは、水平断面が略小判形に形成されている。その形状としては、操作部21Dに同心で設けられた操作部21Dよりも小さな外径の円柱の周面が軸線方向に沿って対向する平面で切断された側面形状で形成されている。   The intermediate portion 21A provided below the first step portion 21E at the lower end of the operation portion 21D has a horizontal cross section that is substantially oval. As its shape, it is formed in a side surface shape in which a circumferential surface of a cylinder having an outer diameter smaller than that of the operation unit 21D provided concentrically with the operation unit 21D is cut by a plane facing in the axial direction.

また、中間部21A下方に続く作動部21Bは、水平断面が略矩形に形成されており、その作動部21Bの側面は、上記中間部21Aの側面と同一平面で形成されている。そして、この作動部21Bは、中間部21A下端の第二段部21Fから下方が上記中間部21Aより拡径した形状、つまり作動部21Bの略矩形における長手方向の寸法が、上記中間部21Aの小判における長手寸法より大きな寸法に設定されている。なお、操作軸21の下端部21Cとなる作動部21Bの下面は平板状に構成されている。   In addition, the actuating part 21B following the intermediate part 21A has a substantially rectangular horizontal cross section, and the side surface of the actuating part 21B is formed in the same plane as the side face of the intermediate part 21A. The operating part 21B has a shape in which the lower part of the lower end of the intermediate part 21A from the second step part 21F is larger in diameter than the intermediate part 21A, that is, the longitudinal dimension of the substantially rectangular shape of the operating part 21B is that of the intermediate part 21A. It is set to a dimension larger than the longitudinal dimension in the oval. In addition, the lower surface of the action | operation part 21B used as the lower end part 21C of the operating shaft 21 is comprised by flat form.

22は、中心に嵌合孔22Aを有した円形突部22Bが、平板部22Cの中央位置で上方に突出形成された軸受で、この軸受22の嵌合孔22A上部に上記操作軸21の操作部21D下部が、回転運動及び上下動が可能に嵌合保持されている。   Reference numeral 22 denotes a bearing in which a circular protrusion 22B having a fitting hole 22A at the center protrudes upward at the center position of the flat plate portion 22C, and the operation shaft 21 is operated above the fitting hole 22A of the bearing 22. The lower part of the portion 21D is fitted and held so as to be capable of rotating and moving up and down.

23は、円板部23Aの上面中心に垂直に突出した円筒部23Bを有する絶縁樹脂製の回転体であり、その円板部23A下面には回転電気部材としてなる平面接点板6がインサート成形により固定されている。上記平面接点板6は、環状の導電性金属薄板に放射状に孔があけられて形成されており、円板部23A下面に櫛歯状で露出する接点を構成している。   23 is a rotating body made of an insulating resin having a cylindrical portion 23B projecting perpendicularly to the center of the upper surface of the disc portion 23A, and a flat contact plate 6 serving as a rotating electrical member is formed by insert molding on the lower surface of the disc portion 23A. It is fixed. The flat contact plate 6 is formed by radially forming holes in an annular conductive metal thin plate, and constitutes a contact that is exposed in a comb shape on the lower surface of the disc portion 23A.

そして、円筒部23Bの孔形状は、上端位置に設けられた貫通孔23C下端から下方に向けて次第に広がった開口部23Dになっている。上記貫通孔23Cは、上記操作軸21の第一段部21Eから下方が滑らかに挿通可能なように、その投影面積と同じ形状に設けられている。つまり、この実施の形態では操作軸21の作動部21Bと同じ形状の略矩形状の貫通孔23Cに設けられており、上記開口部23Dは貫通孔23Cを構成する最大寸法である矩形における長手側の径方向の寸法位置から下方に向けて次第に広がっている。   The hole shape of the cylindrical portion 23B is an opening portion 23D that gradually expands downward from the lower end of the through hole 23C provided at the upper end position. The through hole 23C is provided in the same shape as the projected area so that the lower part can be smoothly inserted from the first step part 21E of the operation shaft 21. In other words, in this embodiment, the substantially rectangular through hole 23C having the same shape as the operating portion 21B of the operating shaft 21 is provided, and the opening 23D is a long side of the rectangle which is the maximum dimension constituting the through hole 23C. It gradually spreads downward from the radial dimension position.

また、上記貫通孔23Cの矩形の長手方向側の対向平面と直交する方向に、その貫通孔23Cと同じ矩形状で下方開口の窪み23Eが設けられている。つまり、その窪み23Eを構成する矩形の中心と上記貫通孔23Cの矩形の中心は、同心であり、矩形の中心を回転中心として90度回転した形状となっており、一方が貫通し、他方は上方が閉塞されたものとなっている。   Further, in the direction perpendicular to the opposing plane on the longitudinal direction side of the rectangular shape of the through hole 23C, a depression 23E having the same rectangular shape as the through hole 23C and having a lower opening is provided. That is, the center of the rectangle that forms the recess 23E and the center of the rectangle of the through-hole 23C are concentric, and have a shape that is rotated 90 degrees around the center of the rectangle. The upper part is closed.

なお、操作軸21の中間部21Aの長さは、上記回転体23の貫通孔23Cの長さより長く設定されている。   The length of the intermediate portion 21A of the operation shaft 21 is set longer than the length of the through hole 23C of the rotating body 23.

そして、上記操作軸21は、上記貫通孔23Cで中間部21Aが回転可能に保持され、上記窪み23E内に上記操作軸21の下方の作動部21Bが組み合わされている。つまり、図1にも示すように、その水平断面の形状が矩形の作動部21Bが窪み23Eに係合されることによって操作軸21の回転運動は回転体23に伝達されるが上下運動は伝わらないようになっている。   The operation shaft 21 is rotatably held at the intermediate portion 21A by the through hole 23C, and an operating portion 21B below the operation shaft 21 is combined in the recess 23E. That is, as shown also in FIG. 1, when the actuating portion 21B having a rectangular horizontal cross section is engaged with the recess 23E, the rotational motion of the operation shaft 21 is transmitted to the rotating body 23, but the vertical motion is transmitted. There is no such thing.

そして、上記回転体23は、その円筒部23Bの外周面が上記軸受22の嵌合孔22Aに回転可能に嵌合保持されている。   The rotating body 23 is fitted and held so that the outer peripheral surface of the cylindrical portion 23 </ b> B can rotate in the fitting hole 22 </ b> A of the bearing 22.

なお、上記軸受22の下面には、嵌合孔22Aと同心となるように弾性薄板金属製のリング状の押えバネ4が組み合わされ、曲げ加工された撓み部分が回転体23の円板部23A上面に弾接しており、回転体23の回転に伴って押えバネ4が摺動して適度な回転トルクを発生させる構成となっている。   Note that a ring-shaped presser spring 4 made of an elastic thin plate metal is combined with the lower surface of the bearing 22 so as to be concentric with the fitting hole 22A, and the bent portion is a disk portion 23A of the rotating body 23. It is in elastic contact with the upper surface, and the presser spring 4 slides with the rotation of the rotating body 23 to generate an appropriate rotational torque.

また、回転体23の平面接点板6が固定された円板部23Aの下方位置には、導電性の弾性金属薄板からなる複数の弾性脚8を絶縁樹脂でインサート成形固定した上方開口箱型の固定基板7が配されており、この固定基板7から伸ばされた各弾性脚8の先端の弾性接点9が、対向した円板部23A下面の上記平面接点板6で櫛歯状に形成された接点面に各々弾接している。すなわち、当該実施の形態のものでは、弾性脚8が固定電気部材、固定基板7が基体としてなる部材となる。   Further, an upper opening box type in which a plurality of elastic legs 8 made of a conductive elastic metal thin plate are insert-molded and fixed with an insulating resin at a position below the disc portion 23A to which the flat contact plate 6 of the rotating body 23 is fixed. The fixed substrate 7 is arranged, and the elastic contact 9 at the tip of each elastic leg 8 extended from the fixed substrate 7 is formed in a comb-like shape by the planar contact plate 6 on the lower surface of the opposing disk portion 23A. Each is in contact with the contact surface. That is, in the embodiment, the elastic leg 8 is a member that is a fixed electric member and the fixed substrate 7 is a member.

なお、回転体23の円板部23Aの下面には、その外周部に細幅リング状の外周突起23Fと上記開口部23D端部外周に細幅リング状の内周突起23Gとが設けられており、両者ともに上記固定基板7面に当接して回転体23は支持されている。   The lower surface of the disk portion 23A of the rotating body 23 is provided with a narrow ring-shaped outer peripheral projection 23F on the outer peripheral portion thereof and a narrow ring-shaped inner peripheral projection 23G on the outer periphery of the opening 23D. Both of them are in contact with the surface of the fixed substrate 7 and the rotating body 23 is supported.

これらの外周突起23F、内周突起23Gは、固定基板7から伸びた弾性脚8と平面接点板6との間隔を確保して弾性接点9と平面接点板6との電気的接続の安定性を得ることにも寄与している。なお、回転体23の円筒部23Bの外周面が上記軸受22の嵌合孔22Aに嵌合保持されているので、操作軸21による回転体23の回転運動は滑らかに行われる。   These outer peripheral protrusions 23F and inner peripheral protrusions 23G ensure the distance between the elastic legs 8 extending from the fixed substrate 7 and the flat contact plate 6 to stabilize the electrical connection between the elastic contacts 9 and the flat contact plate 6. It also contributes to gaining. In addition, since the outer peripheral surface of the cylindrical portion 23B of the rotating body 23 is fitted and held in the fitting hole 22A of the bearing 22, the rotating motion of the rotating body 23 by the operation shaft 21 is smoothly performed.

そして、上記固定基板7の下方にはスイッチ基板10が配置され、その上面中央の凹部10A内には、上記操作軸21と同心位置の中央固定接点11Aとその中央固定接点11Aを挟む外周の等距離位置に外周固定接点11Bがインサート成形により固定されており、外周固定接点11B上には弾性金属薄板製のドーム状可動接点12の外周下端が載せられ、さらにその上方にプッシュ板14が載置されて押圧スイッチ部13が構成されている。   A switch board 10 is disposed below the fixed board 7, and a central fixed contact 11A concentric with the operation shaft 21 and an outer periphery sandwiching the central fixed contact 11A are disposed in a recess 10A at the center of the upper surface. An outer peripheral fixed contact 11B is fixed at a distance position by insert molding, and a lower end of the outer periphery of the dome-shaped movable contact 12 made of an elastic metal thin plate is placed on the outer peripheral fixed contact 11B, and a push plate 14 is placed thereon. Thus, the push switch portion 13 is configured.

ここで、上記操作軸21の作動部21Bと回転体23の窪み23Eとの係合長さは、押圧スイッチ部13の動作距離より長く設定されている。   Here, the engagement length between the operating portion 21 </ b> B of the operation shaft 21 and the recess 23 </ b> E of the rotating body 23 is set to be longer than the operating distance of the pressing switch portion 13.

そして、上記プッシュ板14は、上記固定基板7の中孔から上方部分が露出しており、そのプッシュ板14上端面に上記操作軸21の下端部21Cが当接している。この状態において、操作軸21の第二段部21Fは、回転体23の下方開口の窪み23E天面に当接している。   The upper portion of the push plate 14 is exposed from the hole of the fixed substrate 7, and the lower end portion 21 </ b> C of the operation shaft 21 is in contact with the upper end surface of the push plate 14. In this state, the second step portion 21 </ b> F of the operation shaft 21 is in contact with the top surface of the recess 23 </ b> E in the lower opening of the rotating body 23.

そして、軸受22の円形突部22Bを中央孔から上方に突出させるようにして、軸受22の平板部22Cの上面側から、回転体23を内包状態として軸受22、固定基板7、スイッチ基板10を重ね合わせてコの字形の取付金具15が装着され、スイッチ基板10の底面で脚部15A先端を折り曲げることにより全体が連結固定されている。   Then, the circular protrusion 22B of the bearing 22 is protruded upward from the central hole, and the bearing 22, the fixed substrate 7, and the switch substrate 10 are placed from the upper surface side of the flat plate portion 22C of the bearing 22 with the rotating body 23 included. A U-shaped mounting bracket 15 is mounted in a superposed manner, and the whole is connected and fixed by bending the tip of the leg portion 15A at the bottom surface of the switch board 10.

ここで、軸受22の嵌合孔22Aを介して操作軸21と回転体23とを組み合わせる手順について説明する。   Here, a procedure for combining the operating shaft 21 and the rotating body 23 through the fitting hole 22A of the bearing 22 will be described.

図3は、押えバネ4が取り付けられた軸受22の嵌合孔22Aに回転体23の円筒部23Bを下方から嵌め込むと共に、操作軸21の第一段部21Eから下方を回転体23の貫通孔23Cに上方から挿通させた状態の断面図であり、図4は、図3の状態の底面図である。   3 shows that the cylindrical portion 23B of the rotating body 23 is fitted from below into the fitting hole 22A of the bearing 22 to which the presser spring 4 is attached, and the lower portion of the operating shaft 21 passes through the rotating body 23 from the first step portion 21E. FIG. 4 is a cross-sectional view of the hole 23C inserted from above, and FIG. 4 is a bottom view of the state of FIG.

同図に示したように、まず、操作軸21の作動部21Bを回転体23の貫通孔23Cと同じ方向に合わせて、上記軸受22の嵌合孔22A上方から上記回転体23の貫通孔23Cへ挿入し、第一段部21Eが回転体23の円筒部23B上面に当接した状態とする。この状態において、操作軸21の中間部21Aの長さは、貫通孔23Cより長く設けられているので、作動部21Bの全ての部分は貫通孔23C下方の開口部23D内に位置している。   As shown in the figure, first, the operating portion 21B of the operation shaft 21 is aligned in the same direction as the through hole 23C of the rotating body 23, and the through hole 23C of the rotating body 23 is located above the fitting hole 22A of the bearing 22. The first step portion 21E is in contact with the upper surface of the cylindrical portion 23B of the rotating body 23. In this state, since the length of the intermediate portion 21A of the operation shaft 21 is longer than the through hole 23C, all the portions of the operating portion 21B are located in the opening 23D below the through hole 23C.

続いて、操作軸21をその軸線中心を回転中心として回転体23に対して相対的に回転させる。このとき、操作軸21の作動部21Bは回転体23の貫通孔23C下方の開口部23D内に位置しているので、操作軸21を回転体23に対して相対的に回転させることが可能となる。図5および図6に、操作軸21を操作部21D側から見て右回転で45度回転した時の回転途中状態を示す。   Subsequently, the operation shaft 21 is rotated relative to the rotating body 23 around the axis center. At this time, since the operating portion 21B of the operating shaft 21 is located in the opening 23D below the through hole 23C of the rotating body 23, the operating shaft 21 can be rotated relative to the rotating body 23. Become. 5 and 6 show a state in the middle of rotation when the operation shaft 21 is rotated 45 degrees clockwise when viewed from the operation unit 21D side.

そして、図7および図8に示すように、操作軸21をさらに回転させていき、図3、図4で示した操作軸21の挿入時の位置から90度回転させ、操作軸21の作動部21Bと回転体23の窪み23Eとの位置を上下で合致させる。   Then, as shown in FIGS. 7 and 8, the operating shaft 21 is further rotated, rotated 90 degrees from the insertion position of the operating shaft 21 shown in FIGS. 3 and 4, and the operating portion of the operating shaft 21 is operated. The positions of 21 </ b> B and the recesses 23 </ b> E of the rotating body 23 are matched vertically.

その状態から、図9に示すように、操作軸21の第二段部21Fが回転体23の窪み23E天面に当接するまで操作軸21を上方に引き上げることにより、操作軸21と回転体23との組み合わせが完了する。なお、その状態で、操作軸21の操作部21D下部が、軸受22の嵌合孔22Aで保持されるように嵌合孔22Aの長さ等を設定している。   From this state, as shown in FIG. 9, the operating shaft 21 and the rotating body 23 are pulled up by pulling the operating shaft 21 upward until the second step portion 21 </ b> F of the operating shaft 21 contacts the top surface of the recess 23 </ b> E of the rotating body 23. The combination with is completed. In this state, the length of the fitting hole 22A is set so that the lower portion of the operation portion 21D of the operation shaft 21 is held by the fitting hole 22A of the bearing 22.

なお、操作軸21の小判形の中間部21Aは、円柱形としても良い。但し、このときも作動部21Bは上記同様の水平断面で略矩形または小判形状のものとし、その略矩形や小判形状を構成する対向する側面で回転体23に回転運動を伝えるようにすると共に、上記作動部21Bの略矩形または小判形状の長手側の寸法を、上記円柱形に形成された中間部の外径より拡径させておくことが重要である。つまり、その寸法差が第二段部としてなり抜け止め用の係止部分となるためである。   The oval middle portion 21A of the operation shaft 21 may be a cylindrical shape. However, at this time as well, the actuating portion 21B has a substantially rectangular or oval shape with the same horizontal cross section as described above, and transmits the rotational motion to the rotating body 23 on the opposite side surfaces constituting the substantially rectangular or oval shape, It is important to make the dimension of the longitudinal side of the substantially rectangular or oval shape of the operating portion 21B larger than the outer diameter of the intermediate portion formed in the cylindrical shape. That is, the dimensional difference becomes the second step portion and becomes a locking portion for retaining the stopper.

次に、この回転操作型エンコーダの動作について説明すると、まず操作軸21の操作部21Dを回転操作すると、操作軸21の回転運動に伴って回転体23が回転して、平面接点板6が固定されて構成された櫛歯状の接点面に対し弾性脚8から伸びた複数の弾性接点9が各々摺動接触して弾性脚8に接続された端子16からパルス信号が得られる。この回転操作時には操作軸21は上下方向には動かず、押圧スイッチ部13は動作しない。   Next, the operation of the rotary operation type encoder will be described. First, when the operation portion 21D of the operation shaft 21 is rotationally operated, the rotating body 23 rotates with the rotational motion of the operation shaft 21, and the flat contact plate 6 is fixed. A plurality of elastic contacts 9 extending from the elastic leg 8 are brought into sliding contact with the comb-shaped contact surface thus configured, and a pulse signal is obtained from the terminal 16 connected to the elastic leg 8. During this rotation operation, the operation shaft 21 does not move in the vertical direction, and the push switch unit 13 does not operate.

一方、図10に示す図中の矢印のように、操作軸21の操作部21Dに押し力を加えて下方に動かすと、その下端部21Cがプッシュ板14を介して、ドーム状可動接点12を押してドーム状部分を弾性反転させ、その下面が対向した中央固定接点11Aに接触する。これにより、ドーム状可動接点12を介して外周固定接点11Bと中央固定接点11A間が電気的に導通し、押圧スイッチ部13がオンする。この操作軸21の押圧時に、回転体23は下方へは動かず、勿論回転運動もしないのでパルス信号の出力はされない。   On the other hand, when a downward force is applied to the operation portion 21D of the operation shaft 21 and the lower end portion 21C is moved through the push plate 14 as indicated by an arrow in FIG. The dome-shaped portion is elastically inverted by pressing, and the lower surface thereof contacts the opposed central fixed contact 11A. As a result, the outer peripheral fixed contact 11B and the central fixed contact 11A are electrically connected via the dome-shaped movable contact 12, and the pressing switch portion 13 is turned on. When the operating shaft 21 is pressed, the rotating body 23 does not move downward and of course does not rotate, so that no pulse signal is output.

そして、操作軸21の操作部21Dへの押圧を解除すると、ドーム状可動接点12の復元力によって、プッシュ板14が上方に押し上げられ、それに伴い操作軸21も押し戻されて押圧スイッチ部13がオフの元の図1に示す状態に戻る。   When the pressing of the operating shaft 21 to the operating portion 21D is released, the push plate 14 is pushed upward by the restoring force of the dome-shaped movable contact 12, and the operating shaft 21 is also pushed back accordingly, so that the pressing switch portion 13 is turned off. The original state shown in FIG.

なお、この押圧スイッチ部13の操作距離は、操作軸21の第一段部21Eが回転体23の円筒部23B上面に当接するまでの移動量よりも小さい設定としている。つまり、上記スイッチ操作時にも第一段部21Eと回転体23の円筒部23B上面との間に空間が確保されるようにしている。   The operation distance of the pressing switch unit 13 is set to be smaller than the movement amount until the first step portion 21E of the operation shaft 21 contacts the upper surface of the cylindrical portion 23B of the rotating body 23. That is, a space is secured between the first step portion 21E and the upper surface of the cylindrical portion 23B of the rotating body 23 even when the switch is operated.

また、作動部21Bが回転体23の窪み23E内に重なっている寸法は、上記押圧スイッチ部13の操作距離より長く設定してあるため、そのスイッチ操作時にも操作軸21の第二段部21Fが窪み23E内から外れることもなく、その係合形状からして操作軸21の上下操作に際し回転体23を回転運動させずに押圧スイッチ部13を操作可能としている。   Further, the dimension in which the actuating portion 21B overlaps the recess 23E of the rotating body 23 is set to be longer than the operation distance of the pressing switch portion 13, so that the second step portion 21F of the operation shaft 21 is also operated during the switch operation. Therefore, the push switch portion 13 can be operated without rotating the rotating body 23 when the operating shaft 21 is operated up and down due to its engagement shape.

このように本実施の形態によれば、従来のようにC形リングを用いたりせず、またその取り付け工程なども必要とせずに、操作軸21を回転体23の貫通孔23Cに挿通した後、90度回転させてから引き上げるのみで、回転体23の窪み23E上面で操作軸21の第二段部21F上面が固定係止された操作軸21の抜け止め機構を有するものにできる。   As described above, according to the present embodiment, after the operation shaft 21 is inserted into the through hole 23 </ b> C of the rotating body 23 without using a C-shaped ring as in the prior art and without requiring an attachment process or the like. Rotating 90 degrees and then pulling up can provide a mechanism for preventing the operating shaft 21 from slipping off, with the upper surface of the second step portion 21F of the operating shaft 21 fixedly locked on the upper surface of the recess 23E of the rotating body 23.

また、上述したように操作軸21でスイッチ操作可能なものとすると、その回転運動及び上下動作可能な回転操作型エンコーダ(回転操作型電子部品)を、容易に実現できると共に、その組立作業効率は良く作業工数を低減させることができる。   Further, if the switch can be operated by the operation shaft 21 as described above, the rotary operation type encoder (rotation operation type electronic component) capable of rotating and moving up and down can be easily realized, and the assembly work efficiency is as follows. The work man-hour can be reduced well.

なお、上記には、押圧スイッチ部13としてドーム状可動接点12を用いた操作ストロークの短いスイッチを備えさせた構成の実施の形態を説明したが、図11に示すように、傾斜した舌片を中央位置に備えた板状可動接点24上に、お椀を伏せた形状のラバードーム25を重ねて構成される操作ストロークの長いスイッチを備えさせた回転操作型エンコーダとしても良く、この場合でも操作軸26の作動部26Aと回転体27の窪み27Aとの係合寸法などは上述と同様の設定とすれば良い。なお、そのスイッチ構成としては、上記に説明したものに限られず、例えばプッシュ板14を無くしたもの等としてもよい。   In the above, the embodiment in which the switch having a short operation stroke using the dome-shaped movable contact 12 is provided as the pressing switch portion 13 has been described. However, as shown in FIG. It may be a rotary operation type encoder provided with a switch having a long operation stroke constituted by laminating a rubber dome 25 having a face-down shape on a plate-like movable contact 24 provided at the center position. The engagement dimension between the 26 actuating portions 26A and the recess 27A of the rotating body 27 may be set as described above. The switch configuration is not limited to that described above, and for example, the push plate 14 may be omitted.

また、図12に示すように、スイッチ基板10の代わりに底板部材28を配して、その底板部材28の中央に設けた凸部28Aを操作軸21の下端部21Cと当接させたもの、つまり操作軸21の上下動作を規制して押圧スイッチ部を備えない形態としても良い。この場合には、さらには底板部材28と固定基板7を一体形成したもの等としても良い。   In addition, as shown in FIG. 12, a bottom plate member 28 is disposed instead of the switch substrate 10, and a convex portion 28 </ b> A provided at the center of the bottom plate member 28 is brought into contact with the lower end portion 21 </ b> C of the operation shaft 21. That is, the vertical movement of the operation shaft 21 may be restricted and the pressing switch portion may not be provided. In this case, the bottom plate member 28 and the fixed substrate 7 may be integrally formed.

なお、以上には回転操作で動作する機能部としてエンコーダを用いたものを説明したが、その代わりに可変抵抗器あるいはその他回転操作によって動作する機能部を有するものであっても良い。またエンコーダとしても上記に説明した構成以外のものであっても良い。   In addition, although what used the encoder as a function part which operate | moves by rotation operation was demonstrated above, you may have a function part which operate | moves by a variable resistor or other rotation operation instead. Also, the encoder may have a configuration other than that described above.

本発明による回転操作型電子部品は、C形リングが不要でその取り付け工程も不要であるにも拘わらず、操作軸の確実な抜け止め状態が確保でき、かつ組立作業の効率化も図れるという特徴を有し、各種AV機器の音量調整、音質調整等の入力操作部等を構成する際に有用である。   The rotary operation type electronic component according to the present invention is characterized in that a C-shaped ring is not required and its mounting process is not required, and thus a reliable securing state of the operation shaft can be secured and the assembly work can be made more efficient. And is useful when configuring an input operation unit or the like for volume adjustment and sound quality adjustment of various AV devices.
