Description

本発明は、１つの操作軸で、プッシュスイッチのＯＮ／ＯＦＦ操作と、パルススイッチ、或いは可変抵抗器等の回転型電気部品を操作するようにしたプッシュスイッチ付き回転型電気部品に関する。   The present invention relates to a rotary electrical component with a push switch, which is configured to operate a rotary electrical component such as a pulse switch or a variable resistor with a single operating shaft and an ON / OFF operation of the push switch.

従来のプッシュスイッチ付き回転型電気部品を図９に基づいて説明すると、合成樹脂からなるケース部材１を有し、このケース部材１には、金属板からなる複数個の導電パターン（導電板）２が埋設されている。
前記ケース部材１には、合成樹脂から成る駆動体３が回転可能に支持されており、駆動体３には、金属板からなる摺動子４が取り付けられている。
そして、この駆動体３が回転することにより、摺動子４が導電パターン（導電板）２に接離して、接点の切り換えを行うパルススイッチを構成している。 A conventional rotary electrical component with a push switch will be described with reference to FIG. 9. A case member 1 made of a synthetic resin is provided. The case member 1 includes a plurality of conductive patterns (conductive plates) 2 made of a metal plate. Is buried.
A drive body 3 made of synthetic resin is rotatably supported on the case member 1, and a slider 4 made of a metal plate is attached to the drive body 3.
When the driving body 3 rotates, the slider 4 contacts and separates from the conductive pattern (conductive plate) 2 to form a pulse switch for switching the contact.

また、ケース部材１の外周壁には、後述する取付部材である軸受け部材１６の平板部１６ａとの間に挟持されて金属板からなる板材５が取り付けられている。
前記板材５には、弾性片５ａが形成され、この弾性片５ａが駆動体３に形成した凹凸部（図示せず）に係脱することにより、駆動体３の回転動作に対してクリック動作を行わしめている。
また、軸受け部材１６は、金属からなり平板部１６ａと軸受け部１６ｂとが形成され、軸受け部１６ｂに支持された操作軸１７が回転自在になっている。 A plate member 5 made of a metal plate is attached to the outer peripheral wall of the case member 1 so as to be sandwiched between a flat plate portion 16a of a bearing member 16 which is an attachment member described later.
An elastic piece 5 a is formed on the plate member 5, and the elastic piece 5 a engages and disengages with a concavo-convex portion (not shown) formed on the drive body 3, thereby performing a click operation with respect to the rotation operation of the drive body 3. It is done.
The bearing member 16 is made of metal and has a flat plate portion 16a and a bearing portion 16b. An operation shaft 17 supported by the bearing portion 16b is rotatable.

前記操作軸１７は、合成樹脂等の成型品からなり、先端に細軸状のバネ押圧部１７ａと、このバネ押圧部１７ａ近傍の割溝１７ｂを挟んで一対の取付脚１７ｃが形成されている。また、ケース部材１の後部（図示左側）には、固定接点８、９を埋設した絶縁体１０が取り付けられ、この絶縁体１０の内部には、ドーム状の板ばね１１が配設されている。
前記板ばね１１は、外周部が固定接点９に常時接触し、その中央部に操作軸１７のバネ押圧部１７ａが当接し、操作軸１７が常時矢印Ａ方向に弾性付勢されている。 そして、板ばね１１により矢印Ａ方向に弾性付勢される操作軸１７は、一対の取付脚１７ｃが駆動体３に係止されて抜け止めされている。 The operation shaft 17 is made of a molded product such as a synthetic resin, and a pair of mounting legs 17c are formed at the tip with a narrow shaft-like spring pressing portion 17a and a split groove 17b in the vicinity of the spring pressing portion 17a. . Further, an insulator 10 in which fixed contacts 8 and 9 are embedded is attached to the rear part (left side in the figure) of the case member 1, and a dome-shaped leaf spring 11 is disposed inside the insulator 10. .
The leaf spring 11 is always in contact with the fixed contact 9 at the outer peripheral portion, the spring pressing portion 17a of the operation shaft 17 is in contact with the central portion thereof, and the operation shaft 17 is always elastically biased in the direction of arrow A. The operation shaft 17 that is elastically urged in the direction of arrow A by the leaf spring 11 is prevented from coming off by a pair of mounting legs 17c being locked to the drive body 3.

このような従来のプッシュスイッチ付き回転型電気部品の操作を説明すると、まず回転型電気部品の操作は、図９に示すように、板ばね１１のばね力で操作軸１７が矢印Ａ方向にスライドした状態の初期状態において、操作軸１７を回転操作すると、駆動体３が回転して回転型電気部品であるパルススイッチが操作される。
また、プッシュスイッチの操作は、図９に示す初期状態にある操作軸１７を矢印Ｂ方向にプッシュ操作すると、バネ押圧部１７ａがドーム状の板ばね１１の中央部を押し、板ばね１１を介して固定接点８と９とが導通してプッシュスイッチのスイッチ回路がＯＮする。
その後、操作軸１７の押圧を解除すると、板ばね１１のばね性により、板ばね１１が固定接点８から離れてプッシュスイッチのスイッチ回路がＯＦＦとなると共に、操作軸１７が矢印Ａ方向にスライドして初期状態に自動復帰する。
特開平１１−９６８５５号公報 The operation of such a conventional rotary electrical component with a push switch will be described. First, as shown in FIG. 9, the operation shaft 17 is slid in the direction of arrow A by the spring force of the leaf spring 11. In the initial state, when the operation shaft 17 is rotated, the driving body 3 rotates and the pulse switch, which is a rotating electrical component, is operated.
The push switch is operated by pushing the operation shaft 17 in the initial state shown in FIG. 9 in the direction of arrow B, and the spring pressing portion 17a pushes the central portion of the dome-shaped leaf spring 11, and the leaf spring 11 is interposed. Thus, the fixed contacts 8 and 9 are brought into conduction, and the switch circuit of the push switch is turned ON.
Thereafter, when the pressing of the operating shaft 17 is released, the leaf spring 11 is separated from the fixed contact 8 due to the spring property of the leaf spring 11, and the switch circuit of the push switch is turned OFF, and the operating shaft 17 slides in the direction of arrow A. To automatically return to the initial state.
JP-A-11-96855

しかし、従来のプッシュスイッチ付き回転型電気部品は、例えば車内温度が５０〜８０℃の高温になる自動車等に使用した場合、合成樹脂からなる操作軸１７が膨張し、操作軸１７と軸受け部材１６の軸受け部１６ｂとの嵌合がきつくなる。
すると、操作軸１７の回転操作性が悪くなるだけでなく、操作軸１７の軸受け部１６ｂに対するスライド性も悪くなる。
そして、このような高温環境下で、膨張した操作軸１７に強い押圧力を加えてプッシュスイッチのスイッチ回路をＯＮさせた後、操作軸１７に加えていた押圧荷重を解除しても、板ばね１１の弾性力だけでは、操作軸１７が矢印Ａ方向にスライドできなくなり、プッシュスイッチのスイッチ回路をＯＦＦできなくなるような障害が発生するおそれがあった。 However, when the conventional rotary electrical component with a push switch is used in, for example, an automobile having a high temperature of 50 to 80 ° C., the operation shaft 17 made of synthetic resin expands, and the operation shaft 17 and the bearing member 16 are expanded. The fitting with the bearing portion 16b becomes tight.
Then, not only the rotation operability of the operation shaft 17 is deteriorated, but also the slidability of the operation shaft 17 with respect to the bearing portion 16b is deteriorated.
Even if the pressing load applied to the operating shaft 17 is released after applying a strong pressing force to the expanded operating shaft 17 to turn on the switch circuit of the push switch in such a high temperature environment, the leaf spring With only the elastic force of 11, the operation shaft 17 cannot slide in the direction of the arrow A, and there is a possibility that a failure may occur such that the switch circuit of the push switch cannot be turned off.

また、このような障害の発生を防止するために、従来のプッシュスイッチ付き回転型電気部品は、使用温度範囲を狭くして、環境温度が所定温度以上では使わないようにしていたので用途が限定されていた。
本発明は前述したような課題を解決し、高温環境下において操作軸のプッシュ操作を解除した時に、プッシュスイッチのスイッチ回路を確実にＯＦＦさせることができるプッシュスイッチ付き回転型電気部品を提供することを目的とする。 In addition, in order to prevent the occurrence of such troubles, conventional rotary electrical parts with push switches have a limited use temperature because the operating temperature range is narrowed so that the ambient temperature does not exceed the specified temperature. It had been.
The present invention solves the problems as described above, and provides a rotary electrical component with a push switch that can reliably turn off the switch circuit of the push switch when the push operation of the operation shaft is released in a high temperature environment. With the goal.

前記課題を解決するための第１の手段として本発明のプッシュスイッチ付き回転型電気部品は、合成樹脂からなる操作軸と、この操作軸を回転操作可能で軸線方向へプッシュ操作可能に支持する軸受け部を有する軸受け部材と、前記操作軸の回転に伴って相対的に摺動する摺動子及び導電パターンと、前記操作軸の軸線方向にプッシュ操作することにより反転可能な板ばねを有するプッシュスイッチとを備え、前記操作軸には、初期状態で前記軸受け部に回転可能に嵌合する太径の第１軸部と、この第１軸部より細径な第２軸部とが形成され、前記操作軸を前記プッシュ操作して前記板ばねが反転した際には、前記操作軸の前記第１軸部と前記軸受け部との嵌合が外れて前記第２軸部が前記軸受け部に嵌合し、前記操作軸の前記プッシュ操作を解除すると、前記板ばねの弾性力で、前記操作軸がプッシュ操作前の初期状態に復帰して前記第１軸部が前記軸受け部に嵌合することを特徴とする。
また、前記課題を解決するための第２の手段として、前記操作軸の前記第２軸部は、前記第１軸部から離れるにしたがって径が細くなるようなテーパ面を周方向に備え、前記操作軸をプッシュ操作して前記板ばねが反転した際には、前記テーパ面が前記軸受け部に位置して嵌合するようにした。 As a first means for solving the above-mentioned problem, a rotary electric component with a push switch according to the present invention includes an operation shaft made of synthetic resin, and a bearing that supports the operation shaft so that the operation shaft can be rotated and pushed in the axial direction. A push switch having a bearing member having a portion, a slider and a conductive pattern that slide relative to each other as the operation shaft rotates, and a leaf spring that can be reversed by a push operation in the axial direction of the operation shaft The operating shaft is formed with a first shaft portion having a large diameter that is rotatably fitted to the bearing portion in an initial state, and a second shaft portion having a smaller diameter than the first shaft portion. When the leaf spring is reversed by pushing the operation shaft, the first shaft portion and the bearing portion of the operation shaft are disengaged and the second shaft portion is fitted to the bearing portion. The push operation of the operation shaft When released, the elastic force of the leaf spring, said operating shaft is the first shaft portion and returns to the initial state before the push operation is characterized in that fitted into the bearing portion.
Further, as a second means for solving the problem, the second shaft portion of the operation shaft is provided with a tapered surface in the circumferential direction such that the diameter thereof becomes narrower as the distance from the first shaft portion increases. When the operation shaft is pushed and the leaf spring is reversed, the tapered surface is positioned and fitted to the bearing portion.

また、前記課題を解決するための第３の手段として、前記軸受け部材には、前記軸受け部の孔径より大きな孔径の筒状部を有し、前記操作軸を前記プッシュ操作した時の前記第１軸部は、前記筒状部に位置するようにした。
また、前記課題を解決するための第４の手段として、前記操作軸は、ガラス繊維が充填されて形成され、一端部側に前記板ばねを押圧操作可能なばね押圧部が形成されると共に、他端部側の端面にゲート部が形成されている構成とした。 As a third means for solving the above-mentioned problem, the bearing member has a cylindrical portion having a hole diameter larger than the hole diameter of the bearing portion, and the first operation when the operation shaft is pushed. The shaft portion was positioned on the cylindrical portion.
As a fourth means for solving the above-mentioned problem, the operation shaft is formed by being filled with glass fiber, and a spring pressing portion capable of pressing the leaf spring is formed on one end side, The gate portion is formed on the end surface on the other end side.

本発明のプッシュスイッチ付き回転型電気部品の操作軸には、初期状態で軸受け部に回転可能に嵌合する太径の第１軸部と、この第１軸部より細径な第２軸部とが形成され、操作軸をプッシュ操作して板ばねが反転した際には、操作軸の第１軸部と軸受け部との嵌合が外れて第２軸部が軸受け部に嵌合し、操作軸のプッシュ操作を解除すると、板ばねの弾性力で、操作軸がプッシュ操作前の初期状態に復帰して第１軸部が軸受け部に嵌合するので、高温環境下で使用するときに操作軸をプッシュ操作してプッシュスイッチのスイッチ回路をＯＮとした後、プッシュ操作を解除した時に、操作軸が熱で膨張していても、軸受け部には第１軸部よりも細径の第２軸部が嵌合しているため、プッシュスイッチのスイッチ回路をＯＦＦさせることができる。これにより、本発明のプッシュスイッチ付き回転型電気部品の使用温度範囲を広げることができる。
また、操作軸の第２軸部は、第１軸部から離れるにしたがって径が細くなるようなテーパ面を周方向に備え、操作軸をプッシュ操作して板ばねが反転した際には、テーパ面が軸受け部に位置して嵌合するようにしたので、操作軸は、第２軸部のテーパ面が軸受け部に案内されて円滑にスライド移動しやすくなる。このため、高温環境下において、操作軸をプッシュ操作して解除した場合にも、プッシュスイッチのスイッチ回路をより確実にＯＮからＯＦＦとすることができる。 The operation shaft of the rotary electric part with push switch according to the present invention includes a first shaft portion having a large diameter that is rotatably fitted to the bearing portion in an initial state, and a second shaft portion having a smaller diameter than the first shaft portion. And when the leaf spring is reversed by pushing the operation shaft, the first shaft portion and the bearing portion of the operation shaft are disengaged and the second shaft portion is fitted to the bearing portion, When the push operation of the operation shaft is released, the elastic force of the leaf spring causes the operation shaft to return to the initial state before the push operation and the first shaft portion is fitted to the bearing portion. After pushing the operating shaft and turning on the switch circuit of the push switch, even when the operating shaft expands due to heat when the push operation is released, the bearing portion has a smaller diameter than the first shaft portion. Since the two shaft parts are fitted, the switch circuit of the push switch can be turned off. That. Thereby, the operating temperature range of the rotary electrical component with a push switch of the present invention can be expanded.
In addition, the second shaft portion of the operation shaft has a tapered surface in the circumferential direction such that the diameter becomes narrower as the distance from the first shaft portion increases. When the leaf spring is reversed by pushing the operation shaft, the taper is tapered. Since the surface is positioned and fitted to the bearing portion, the operation shaft is easily slid smoothly as the tapered surface of the second shaft portion is guided by the bearing portion. For this reason, even when the operating shaft is pushed and released in a high temperature environment, the switch circuit of the push switch can be more reliably turned from ON to OFF.

また、軸受け部材には、軸受け部の孔径より大きな孔径の筒状部を有し、操作軸をプッシュ操作した時の第１軸部は、筒状部に位置しているので、操作軸をより確実に復帰させて、プッシュスイッチのスイッチ回路をＯＦＦさせることができる。
また、操作軸は、ガラス繊維が所定量充填されて形成され、一端部側に板ばねを押圧操作可能なばね押圧部が形成されると共に、他端部側の端面にゲート部が形成されているので、充填しているガラス繊維の充填方向を軸線方向に配列させることができる。
そのために、操作軸の強度を高めることができ、繰り返しの回転操作、プッシュ操作でも操作軸の摩耗を少なくすることができる。 Further, the bearing member has a cylindrical portion having a hole diameter larger than the hole diameter of the bearing portion, and the first shaft portion when the operating shaft is pushed is positioned at the cylindrical portion, so that the operating shaft is more The switch circuit of the push switch can be turned off by reliably returning.
The operation shaft is formed by filling a predetermined amount of glass fiber, a spring pressing portion capable of pressing the leaf spring is formed on one end portion side, and a gate portion is formed on the end surface on the other end side. Therefore, the filling direction of the filled glass fibers can be arranged in the axial direction.
Therefore, the strength of the operation shaft can be increased, and wear of the operation shaft can be reduced even in repeated rotation operations and push operations.

At this time, the plate member 5 is sandwiched between the side wall 1 d of the case member 1 and the flat plate portion 6 a of the bearing member 6.

また、筒状部６ｂ及び軸受け部６ｃに挿通される操作軸７は、合成樹脂製の成型品からなり、強度向上のために樹脂材料に所定量のガラス繊維が充填されて成型加工されている。
そのために、耐摩耗性に優れており、操作軸７を繰り返し回転操作、あるいはプッシュ操作を行っても、回転摺動部の摩耗による不具合の発生を防止できるようになっている。
前記操作軸７は、図２、図３に示すように、左端部の先端部側（非操作部側）で軸線Ｓ上に細軸のばね押圧部７ａが形成され、このばね押圧部７ａの図示上下に、所定の幅寸法と深さ寸法の割溝７ｂが軸線Ｓ方向に沿って形成されている。
また、割溝７ｂを挟んだ、ばね押圧部７ａの図示上下には、一対の取付脚７ｃが形成されている。そして、ばね押圧部７ａは、取付脚７ｃよりも図示左側に突出形成されている。 Further, the operating shaft 7 inserted through the cylindrical portion 6b and the bearing portion 6c is made of a synthetic resin molded product, and a resin material is filled with a predetermined amount of glass fiber and molded to improve the strength. .
Therefore, it has excellent wear resistance, and even if the operation shaft 7 is repeatedly rotated or pushed, it is possible to prevent the occurrence of problems due to wear of the rotating sliding portion.
As shown in FIGS. 2 and 3, the operating shaft 7 is formed with a thin-axis spring pressing portion 7a on the axis S on the tip end side (non-operating portion side) of the left end portion. Split grooves 7b having a predetermined width dimension and depth dimension are formed along the axis S direction at the top and bottom of the drawing.
A pair of mounting legs 7c are formed on the upper and lower sides of the spring pressing portion 7a with the split groove 7b interposed therebetween. The spring pressing portion 7a is formed so as to protrude on the left side in the drawing from the mounting leg 7c.

また、操作軸７の図示右側（操作部側）には、操作摘み（図示せず）が取り付けられる断面Ｄ字状の操作部７ｄが形成され、操作軸７の中央部には、軸受け部材６の軸受け部６ｃに、回転可能及びスライド移動可能で、軸受け部６ｃと微小なクリアランスを有してほとんどガタなく嵌合可能な第１軸部７ｅが形成されている。この第１軸部７ｅの図示右側（操作部側）には、第１軸部７ｅより細径で、第１軸部７ｅと軸受け部６ｃとの間のクリアランスよりも大きなクリアランスを有して、軸受け部６ｃに嵌合可能な第２軸部７ｆが形成されている。すなわち、第１軸部７ｅは、第２軸部７ｆよりも径の大きな太径の軸部となっている。
また、第２軸部７ｆには、第１軸部７ｅから図示右側の操作部側へと離れるにしたがって径が緩やかに細くなるテーパ面７ｇが周方向に形成されている。このテーパ面７ｇは、第２軸部７ｆの一部を構成し、第１軸部７ｅから連続して形成されている。そして、このテーパ面７ｇは、矢印Ｂ方向にプッシュ操作された操作軸７が矢印Ａ方向に復帰するときに、第１軸部７ｅが軸受け部６ｃに嵌合するときのガイドとなっている。 Further, an operation portion 7d having a D-shaped cross section to which an operation knob (not shown) is attached is formed on the right side (operation portion side) of the operation shaft 7 in the figure, and a bearing member 6 is formed at the center of the operation shaft 7. A first shaft portion 7e that is rotatable and slidable and has a small clearance with the bearing portion 6c and can be fitted with little play is formed on the bearing portion 6c. On the right side (operation unit side) of the first shaft portion 7e, the first shaft portion 7e has a smaller diameter than the clearance between the first shaft portion 7e and the bearing portion 6c. A second shaft portion 7f that can be fitted to the bearing portion 6c is formed. That is, the first shaft portion 7e is a thick shaft portion having a larger diameter than the second shaft portion 7f.
Further, the second shaft portion 7f is formed with a tapered surface 7g in the circumferential direction whose diameter gradually decreases as the distance from the first shaft portion 7e toward the operation portion on the right side in the drawing is increased. The tapered surface 7g constitutes a part of the second shaft portion 7f and is formed continuously from the first shaft portion 7e. The tapered surface 7g serves as a guide when the first shaft portion 7e is fitted to the bearing portion 6c when the operation shaft 7 pushed in the arrow B direction returns to the arrow A direction.

また、操作軸７には、第１軸部７ｅの図示左側面に段部７ｈが形成され、この段部７ｈによって、操作軸７を矢印Ｂ方向にプッシュ操作した時に、駆動体３の筒部３ｂ端部に当接するストッパー部となっている。
また、操作軸７は、図３Ｃに示すように、操作部７ｄの図示右端面に、成型加工時のゲート部７ｊが形成されている。
前記操作軸７は、径寸法の大きな操作部７ｄの右端面にゲート部７ｊを設けることで、樹脂材料に所定量充填したガラス繊維の配列方向を、軸線Ｓと略平行となるように配列することができ、操作軸７の強度を高めることができる。 Further, the operation shaft 7 is formed with a step portion 7h on the left side of the first shaft portion 7e in the figure, and when the operation shaft 7 is pushed in the direction of the arrow B by the step portion 7h, the cylinder portion of the driver 3 is formed. It is a stopper part which contacts 3b end part.
Further, as shown in FIG. 3C, the operation shaft 7 is formed with a gate portion 7j at the time of molding on the right end surface of the operation portion 7d.
The operation shaft 7 is arranged so that the arrangement direction of the glass fibers filled with a predetermined amount of the resin material is substantially parallel to the axis S by providing the gate portion 7j on the right end surface of the operation portion 7d having a large diameter. The strength of the operation shaft 7 can be increased.

このような操作軸７は、太径の第１軸部７ｅと、軸受け部材６の軸受け部６ｃとの間のクリアランスは非常に小さく形成されているので、初期状態の操作軸７の第１軸部７ｅは、回転可能及びプッシュ操作に伴うスライド移動可能で軸線Ｓと直交する方向にほとんどガタなく軸受け部６ｃに嵌合している。
即ち、矢印Ｂ方向にプッシュ操作する前の初期状態における操作軸７は、第１軸部７ｅが軸受け部材６の軸受け部６ｃに回転可能及びスライド移動可能で、軸受け部６と微小なクリアランスを有して嵌合している。 Such an operation shaft 7 has a very small clearance between the large-diameter first shaft portion 7e and the bearing portion 6c of the bearing member 6, and therefore the first shaft of the operation shaft 7 in the initial state. The portion 7e is rotatable and slidable in accordance with the push operation, and is fitted to the bearing portion 6c with little play in the direction perpendicular to the axis S.
That is, the operation shaft 7 in the initial state before the push operation in the direction of the arrow B has the first shaft portion 7e rotatable and slidable on the bearing portion 6c of the bearing member 6, and has a small clearance with the bearing portion 6. Are mated.

また、操作軸７は、図２に示す初期状態から後述するプッシュスイッチＰのスイッチ回路がＯＮするまでのストロークが図５に示すように、寸法Ｃとなっている。また、後述するプッシュスイッチＰのスイッチ回路がＯＮした時の操作軸７は、軸受け部６ｃから第１軸部７ｅが図示左側（非操作部側）に抜け出ており、この時の軸受け部６ｃから第１軸部７ｅまでの寸法は、図５に仮想線（破線）で示すように、寸法Ｃより小さい寸法Ｄになるようになっている。
そして、操作軸７は、矢印Ｂ方向のプッシュ操作を解除して、矢印Ａ方向に寸法Ｃのストローク分戻ることで、確実に第１軸部７ｅが軸受け部６ｃと嵌合するようになっている。 Further, the operation shaft 7 has a dimension C as shown in FIG. 5 from the initial state shown in FIG. 2 until the switch circuit of the push switch P described later is turned on. Further, when the switch circuit of the push switch P, which will be described later, is turned on, the operation shaft 7 has a first shaft portion 7e that has come out from the bearing portion 6c to the left side (non-operation portion side) in the drawing, and the bearing portion 6c at this time The dimension up to the first shaft portion 7e is a dimension D smaller than the dimension C, as indicated by a virtual line (broken line) in FIG.
Then, the operation shaft 7 releases the push operation in the arrow B direction and returns in the direction of the arrow A by the stroke of the dimension C, so that the first shaft portion 7e is securely fitted to the bearing portion 6c. Yes.

また、操作軸７を駆動体３に組み付けるには、操作軸７のばね押圧部７ａ側を矢印Ｂ方向に移動させて、駆動体３の筒部３ｂの孔３ａに挿入する。
すると、操作軸７の取付脚７ｃが係止部３ｆの内面に当接し、更に、操作軸７を矢印Ｂ方向に押し込むと、鈎状の取付脚７ｃが割溝７ｂを狭める方向に撓んで係止部３ｆが形成された部分の孔３ａを通過する。
そして、係止部３ｆが形成された部分の孔３ａを通過した取付脚７ｃは、自身のバネ性で元の状態に戻り、鈎状部分が駆動体３の係止部３ｆにスナップ係止される。このことにより、操作軸７は、矢印Ａ方向への抜け止めが行われる。 Further, in order to assemble the operating shaft 7 to the driving body 3, the spring pressing portion 7 a side of the operating shaft 7 is moved in the direction of arrow B and inserted into the hole 3 a of the cylindrical portion 3 b of the driving body 3.
Then, the mounting leg 7c of the operating shaft 7 comes into contact with the inner surface of the locking portion 3f, and further, when the operating shaft 7 is pushed in the direction of arrow B, the hook-shaped mounting leg 7c bends in the direction of narrowing the split groove 7b. It passes through the hole 3a where the stop 3f is formed.
Then, the mounting leg 7c that has passed through the hole 3a in the portion where the locking portion 3f is formed returns to its original state due to its own spring property, and the hook-shaped portion is snap-locked to the locking portion 3f of the driving body 3. The As a result, the operating shaft 7 is prevented from coming off in the direction of arrow A.

また、取付脚７ｃによって駆動体３に抜け止めされた操作軸７は、ばね押圧部７ａが受け部３ｃの小孔３ｄに挿通する。
このことにより、ばね押圧部７ａ側の軸線Ｓと直交する方向のガタ付きが規制されると共に、矢印Ｂ方向にスライド移動可能となっている。
このように駆動体３と係合された操作軸７は、操作部７ｄが板材５の孔（図示せず）と軸受け部材６に筒状部６ｂ側から挿入されて、操作部７ｄが軸受け部６ｃから突出されると共に、摺動子４が取り付けられた駆動体３はケース部材１の凹部１ａに収納される。そして、ケース部材１の後方（図２において左側）に後述する板ばね１１と絶縁体１０を配置した状態で、軸受け部材６の固定爪６ｆを絶縁体１０の後面側に折り曲げることにより、各部材の組み立てが行われる。
このように組み込みされた操作軸７は、プッシュ操作する前の初期状態から、矢印Ｂ方向にプッシュ操作すると、段部７ｈが駆動体３の筒部３ｂ端部にぶつかって、そのスライド移動が停止する。また、プッシュ操作を解除して矢印Ａ方向に戻される操作軸７は、鈎状の取付脚７ｃが係止部３ｆに掛け止めされて、寸法Ｃのストローク分だけスライド移動してそれ以上はスライド移動しない。 Further, the operating shaft 7 that is prevented from being detached from the driving body 3 by the mounting leg 7c is inserted into the small hole 3d of the receiving portion 3c by the spring pressing portion 7a.
As a result, backlash in a direction orthogonal to the axis S on the spring pressing portion 7a side is restricted, and sliding movement is possible in the arrow B direction.
Thus, the operating shaft 7 engaged with the drive body 3 has the operating portion 7d inserted into the hole (not shown) of the plate 5 and the bearing member 6 from the cylindrical portion 6b side, and the operating portion 7d is the bearing portion. The driving body 3 that protrudes from 6 c and has the slider 4 attached thereto is housed in the recess 1 a of the case member 1. Then, in a state where a leaf spring 11 and an insulator 10 which will be described later are disposed behind the case member 1 (left side in FIG. 2), the fixing claws 6f of the bearing member 6 are bent to the rear surface side of the insulator 10 to thereby form each member. Is assembled.
When the operation shaft 7 incorporated in this way is pushed in the direction of the arrow B from the initial state before the push operation, the stepped portion 7h hits the end of the cylindrical portion 3b of the driving body 3, and the sliding movement is stopped. To do. Further, the operation shaft 7 which is released from the push operation and returned in the direction of the arrow A is slid by the stroke of the dimension C, with the hook-shaped mounting leg 7c hooked on the locking portion 3f, and slides beyond that. Do not move.

また、ケース部材１の図示左側の後部には、固定接点８、９を埋設した絶縁体１０が取り付けられ、この絶縁体１０の内部には、可動接点としての金属板からなるドーム状の板ばね１１が配設されている。
前記板ばね１１は、その周辺部が固定接点９に常時接触し、且つ、その中央部が操作軸７のばね押圧部７ａに当接して、操作軸７を常時矢印Ａ方向に弾性付勢している。
そして、固定接点８、９を有する絶縁体１０と、板ばね１１とでプッシュスイッチＰが構成され、このプッシュスイッチＰと回転型電気部品Ｄとが軸線Ｓ上に並列して配設されている。 Further, an insulator 10 in which fixed contacts 8 and 9 are embedded is attached to the rear portion of the case member 1 on the left side of the figure, and a dome-shaped leaf spring made of a metal plate as a movable contact is provided inside the insulator 10. 11 is disposed.
The peripheral portion of the leaf spring 11 is always in contact with the fixed contact 9, and the central portion thereof is in contact with the spring pressing portion 7a of the operation shaft 7, so that the operation shaft 7 is always elastically biased in the arrow A direction. ing.
The insulator 10 having the fixed contacts 8 and 9 and the leaf spring 11 constitute a push switch P. The push switch P and the rotary electrical component D are arranged in parallel on the axis S. .

次ぎに、上述したような構成のプッシュスイッチ付き回転型電気部品の操作を説明する。操作軸７の操作部７ｄを回転操作すると、操作軸７の回転に伴って駆動体３が回転し、駆動体３に取り付けた摺動子４と導電パターン（導電板）２とが相対的に摺動して、回転型電気部品Ｄであるパルススイッチが操作される。
また、図１、図２に示す初期状態の操作軸７を矢印Ｂ方向にプッシュ操作すると、操作軸７先端のばね押圧部７ａが板ばね１１の中央部を押圧して、弾力性のある板ばね１１が反転し、板ばね１１の中央部内面が固定接点８に接触する。
このことにより、固定接点８と９とが板ばね１１を介して導通してプッシュスイッチＰのスイッチ回路がＯＮする。 Next, the operation of the rotary electrical component with push switch having the above-described configuration will be described. When the operating portion 7d of the operating shaft 7 is rotated, the driving body 3 rotates with the rotation of the operating shaft 7, and the slider 4 attached to the driving body 3 and the conductive pattern (conductive plate) 2 are relatively moved. The pulse switch which is the rotating electrical component D is operated by sliding.
Further, when the operation shaft 7 in the initial state shown in FIGS. 1 and 2 is pushed in the direction of the arrow B, the spring pressing portion 7a at the tip of the operation shaft 7 presses the central portion of the leaf spring 11, and the elastic plate The spring 11 is reversed, and the inner surface of the central portion of the leaf spring 11 contacts the fixed contact 8.
As a result, the fixed contacts 8 and 9 are conducted through the leaf spring 11 and the switch circuit of the push switch P is turned on.

前記操作軸７のプッシュ操作において、軸受け部６ｃに嵌合した初期状態の第１軸部７ｅが、軸受け部６ｃから抜け出て筒状部６ｂに位置すると、第１軸部７ｅが筒状部６ｂに対して、初期状態の第１軸部７ｅと軸受け部６ｃとの間のクリアランスよりも大きなクリアランスを有するようになる。
しかし、操作軸７をプッシュ操作してプッシュスイッチＰのスイッチ回路がＯＮした際には、図７に示すように、第２軸部７ｆのテーパ面７ｇが軸受け部６ｃに位置して、テーパ面７ｇが軸受け部６ｃに対して嵌合する状態となる。このとき、テーパ面７ｇと軸受け部６ｃとの間のクリアランスは、初期状態における第１軸部７ｅと軸受け部６ｃとの間の微小クリアランスよりは大きいものの、図７に示すプッシュ操作時における第１軸部７ｅと筒状部６ｂとの間のクリアランスよりは小さくなるように設定されている。このため、操作軸７のプッシュ操作時のガタ付きは、プッシュ操作の操作感触に違和感を覚えるほど大きくなるのを抑制することができる。
また、操作軸７をプッシュ操作する際に、操作部７ｄ側にガタ付きが発生しても、板ばね１１を押圧する側のばね押圧部７ａが、駆動体３の小孔３ｄにガイドされているので、ばね押圧部７ａ側には、ガタ付きが発生しにくいようになっている。
そのために、ばね押圧部７ａは、板ばね１１の略中央部におけるほぼ同じ位置を常に押圧するようになっている。 In the push operation of the operating shaft 7, when the first shaft portion 7e in the initial state fitted to the bearing portion 6c is pulled out of the bearing portion 6c and positioned at the tubular portion 6b, the first shaft portion 7e is moved to the tubular portion 6b. On the other hand, a clearance larger than the clearance between the first shaft portion 7e and the bearing portion 6c in the initial state is provided.
However, when the operating shaft 7 is pushed and the switch circuit of the push switch P is turned on, the tapered surface 7g of the second shaft portion 7f is positioned at the bearing portion 6c as shown in FIG. 7g will be in the state which fits with respect to the bearing part 6c. At this time, the clearance between the tapered surface 7g and the bearing portion 6c is larger than the minute clearance between the first shaft portion 7e and the bearing portion 6c in the initial state, but the first clearance during the push operation shown in FIG. The clearance is set to be smaller than the clearance between the shaft portion 7e and the cylindrical portion 6b. For this reason, it can suppress that the backlash at the time of the push operation of the operating shaft 7 becomes so large that the operation feeling of the push operation becomes uncomfortable.
Further, when the operation shaft 7 is pushed, even if the operation portion 7 d is rattled, the spring pressing portion 7 a that presses the leaf spring 11 is guided by the small hole 3 d of the driving body 3. Therefore, rattling is unlikely to occur on the spring pressing portion 7a side.
Therefore, the spring pressing portion 7a always presses substantially the same position in the substantially central portion of the leaf spring 11.

また、プッシュスイッチＰのスイッチ回路をＯＮさせた後、操作軸７の矢印Ｂ方向のプッシュ操作を解除すると、板ばね１１の弾性力により、操作軸７が矢印Ａ方向に戻される。
そして、板ばね１１と固定接点８とが離れ、プッシュスイッチＰのスイッチ回路がＯＦＦとなると共に、取付脚７ｃが係止部３ｆに掛け止めされて操作軸７の矢印Ａ方向のスライド移動がストップする。 When the push operation of the operation shaft 7 in the arrow B direction is released after the switch circuit of the push switch P is turned on, the operation shaft 7 is returned in the arrow A direction by the elastic force of the leaf spring 11.
Then, the leaf spring 11 and the fixed contact 8 are separated from each other, the switch circuit of the push switch P is turned off, and the mounting leg 7c is hooked on the locking portion 3f, so that the sliding movement of the operation shaft 7 in the direction of arrow A is stopped. To do.

上述したような本発明のプッシュスイッチ付き回転型電気部品は、初期状態にある操作軸７を、寸法Ｃのストローク分プッシュ操作してプッシュスイッチＰのスイッチ回路をＯＮすると、操作軸７の第１軸部７ｅが軸受け部材６の軸受け部６ｃから寸法Ｄだけ外れて軸受け部６ｃよりも大きな孔径の筒状部６ｂに位置し、筒状部６ｂに対してある程度大きなクリアランス（遊び）を有するようになる。
そのために、本発明のプッシュスイッチ付き回転型電気部品を、例えば温度変化が大きな車等に使用して、車内温度が５０℃以上の高温となって、操作軸７が膨張したとしても、操作軸７のプッシュ操作を解除したときに、少なくとも寸法Ｄ分は板ばね１１の弾性力で操作軸７を矢印Ａ方向に戻すことができる。したがって、ＯＮとなっているプッシュスイッチＰのスイッチ回路を確実にＯＦＦさせることができる。 As described above, the rotary electric part with push switch according to the present invention is configured such that when the operation shaft 7 in the initial state is pushed by the stroke of the dimension C and the switch circuit of the push switch P is turned on, the first operation shaft 7 is turned on. The shaft portion 7e is disengaged from the bearing portion 6c of the bearing member 6 by a dimension D and is positioned in the tubular portion 6b having a larger hole diameter than the bearing portion 6c, and has a somewhat large clearance (play) with respect to the tubular portion 6b. Become.
Therefore, even if the rotary electric part with a push switch according to the present invention is used in, for example, a car having a large temperature change and the inside temperature of the car becomes a high temperature of 50 ° C. or more and the operating shaft 7 expands, the operating shaft When the push operation of 7 is released, the operation shaft 7 can be returned in the direction of arrow A by the elastic force of the leaf spring 11 at least for the dimension D. Therefore, the switch circuit of the push switch P that is ON can be reliably turned OFF.

また、プッシュ操作時には、第１軸部７ｅよりも細径の第２軸部７ｆに設けられたテーパ面７ｇが軸受け部６ｃに位置して嵌合しているので、テーパ面７ｇをイドとして操作軸７が矢印Ａ方向へスムーズに移動しやすいものとなっている。さらに、軸受け部材６の軸受け部６ｃと筒状部６ｂとの間に設けられたテーパ部６ｄによっても、第２軸部７ｆのテーパ面７ｇや第１軸部７ｅをガイドすることができ、操作軸７の矢印Ａ方向への移動をより円滑なものとすることができる。よって、テーパ面７ｇやテーパ部６ｄを設けたことにより、プッシュスイッチＰのスイッチ回路をより確実にＯＦＦさせることができる。
また、板ばね１１の弾性力で矢印Ａ方向に戻る操作軸７は、操作軸７の慣性によって、寸法Ｄより大きな寸法戻すことができる。
このような本発明のプッシュスイッチ付き回転型電気部品は、プッシュ操作時に操作軸７の第１軸部７ｅが軸受け部材６の軸受け部６ｃから外れることで、高温環境下でも用いることができ、使用温度範囲を広くすることができる。 Further, at the time of the push operation, the tapered surface 7g provided on the second shaft portion 7f having a diameter smaller than that of the first shaft portion 7e is positioned and fitted to the bearing portion 6c. The shaft 7 is easy to move smoothly in the direction of arrow A. Further, the tapered surface 6g of the second shaft portion 7f and the first shaft portion 7e can be guided also by the taper portion 6d provided between the bearing portion 6c and the cylindrical portion 6b of the bearing member 6, and the operation The movement of the shaft 7 in the arrow A direction can be made smoother. Therefore, by providing the tapered surface 7g and the tapered portion 6d, the switch circuit of the push switch P can be turned off more reliably.
Further, the operating shaft 7 that returns in the direction of arrow A by the elastic force of the leaf spring 11 can be returned to a dimension larger than the dimension D due to the inertia of the operating shaft 7.
Such a rotary electric component with a push switch of the present invention can be used even in a high temperature environment because the first shaft portion 7e of the operation shaft 7 is detached from the bearing portion 6c of the bearing member 6 during the push operation. The temperature range can be widened.

尚、本発明の実施の形態では、第２軸部７ｆにテーパ面７ｇを形成したもので説明したが、テーパ面７ｇを無くして第１軸部７ｅと第２軸部７ｆとを段差状に形成したものでも良い。
このような第１軸部７ｅは、軸受け部材６の筒状部６ｂと軸受け部６ｃとの間に形成したテーパ部６ｄによってガイドすることができる。 In the embodiment of the present invention, the taper surface 7g is formed on the second shaft portion 7f. However, the taper surface 7g is eliminated and the first shaft portion 7e and the second shaft portion 7f are stepped. It may be formed.
Such a first shaft portion 7e can be guided by a tapered portion 6d formed between the cylindrical portion 6b of the bearing member 6 and the bearing portion 6c.
