Description

【0001】
【発明の属する技術分野】
本発明は、主に自動車のブレーキペダル操作時の、ストップランプの点消灯制御等に用いられる車両用プッシュスイッチに関するものである。
【0002】
【従来の技術】
近年、ブレーキペダルを踏み込んだ際にはストップランプを点灯させ、離した際には消灯させる、ブレーキペダルの操作に伴うストップランプの制御用として、押圧操作型の車両用プッシュスイッチが多く使用されている。
【0003】
このような従来の車両用プッシュスイッチについて、図5〜7を用いて説明する。
【0004】
図6は従来の車両用プッシュスイッチの断面図であり、同図において、1は上面開口で略箱型の絶縁樹脂製のケース、2は同じく絶縁樹脂製の作動体で、ケース1には底面から端子部3Aが突出した複数の固定接点3が植設されている。
【0005】
そして、4は導電金属製の可動接点で、この可動接点4がケース1の底面との間にやや撓んだ状態で装着された接圧ばね5によって、複数の固定接点3に下方から弾接し、複数の固定接点3が可動接点4によって電気的に接続されてスイッチ接点が形成されている。
【0006】
また、6はコイル状の戻りばね、7はケース1上面の開口部を覆うカバーで、戻りばね6が作動体2下面とケース1の底面との間にやや撓んだ状態で装着されて、作動体2を上方に付勢している。
【0007】
さらに、カバー7には上方へ突出する中空筒部7Aが設けられ、この中空筒部7A内に作動体2の操作軸2Aが上下動可能に挿通すると共に、操作軸2A上端が中空筒部7Aから上方へ突出して、車両用プッシュスイッチ8が構成されている。
【0008】
以上の構成において、図6に示す、作動体2が戻りばね6によって付勢されて上方で保持された、所謂レリーズ状態から、操作軸2A上端を下方へ押圧操作すると、図7の断面図に示すように、作動体2が戻りばね6を撓めながら下方へ移動すると共に、作動体2下端に上面を押圧された可動接点4が、接圧ばね5を撓めながら下方へ移動して、固定接点3から離れるため、複数の固定接点3の間が電気的に切断された状態となる。
【0009】
そして、操作軸2Aへの押圧力を除くと、戻りばね6の弾性復帰力によって作動体2が上方へ移動すると共に、可動接点4も接圧ばね5に押圧されて固定接点3に弾接し、複数の固定接点3が電気的に接続された、図6のレリーズ状態に戻る。
【0010】
さらに、このように構成された車両用プッシュスイッチ8は、図5の外観図に示すように、一般に自動車のブレーキペダル9の手前に装着され、固定接点3の端子部3Aにはストップランプ(図示せず)に接続されたコネクタ10が装着される。
【0011】
また、ブレーキペダル9が踏み込まれていない場合には、ブレーキペダル9のアーム9Aによって作動体2の操作軸2Aが押圧された状態、つまり複数の固定接点3間が電気的に切断された図7の状態となっているため、ストップランプは消灯した状態となっている。
【0012】
そして、ブレーキペダル9が踏み込まれると、アーム9Aが操作軸2Aから離れ押圧力が除かれるため、戻りばね6によって操作軸2Aが突出し、接圧ばね5によって可動接点4が複数の固定接点3に弾接した図6の状態となり、ストップランプが点灯する。
【0013】
なお、ストップランプに電球が用いられている場合には、CD12V10A程度の比較的大きな電圧電流が通電され、LED等が用いられている場合には、DC12V0.5A〜1A程度の比較的小さな電流が通電されるように構成されている。
【0014】
また、この出願の発明に関連する先行技術文献情報としては、例えば、特許文献1が知られている。

【発明が解決しようとする課題】
しかしながら、上記従来の車両用プッシュスイッチにおいては、大電流が通電された場合には、接離する際のアーク放電等により接点表面に炭化物や損傷が生じ、小電流が通電された場合には、接点面に炭化被膜や酸化被膜などが生じるが、可動接点4と固定接点3が常に同じ箇所で接触しているため、これらにより接触が不安定なものになり易いという課題があった。
【0017】
本発明は、このような従来の課題を解決するためのものであり、小電流から大電流まで幅広い範囲での使用が可能で、安定した接触が得られる車両用プッシュスイッチを提供することを目的とするものである。
【0018】
【課題を解決するための手段】
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。
【0019】
本発明の請求項1に記載の発明は、ばねに付勢された可動接点が固定接点に弾接した時に、この可動接点の両端部が弾性変形するようにして車両用プッシュスイッチを構成したものであり、可動接点両端部の弾性変形によって、可動接点と固定接点が接離する際に接触箇所が変化する、所謂、接点のワイピング作用が得られるため、簡易な構成で、小電流から大電流まで幅広い範囲で接触の安定した車両用プッシュスイッチを得ることができるという作用を有する。
【0020】
請求項2に記載の発明は、請求項1記載の発明において、導電金属製の支持体を可動接点とばねとの間に配置すると共に、上記可動接点が固定接点に弾接した時、上記可動接点の両端を支持体に当接させたものであり、可動接点両端部の変形量を所定の状態に保つことができると共に、可動接点に加え支持体も導体として通電されるため、さらに安定した接触を得ることができるという作用を有する。
【0021】
【発明の実施の形態】
以下、本発明の実施の形態について、図1〜図5を用いて説明する。
【0022】
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。
【0023】
(実施の形態)
図1は本発明の一実施の形態による車両用プッシュスイッチの断面図、図2は同分解斜視図であり、同図において、11は上面開口で略箱状の絶縁樹脂製のケース、12は略円柱状で同じく絶縁樹脂製の作動体で、ケース11には、底面から端子部13Aが突出し、作動体12の両側に略ドーム状の接点部13Bが形成された、複数の固定接点13が植設されている。
【0024】
そして、14は固定接点13と両端部が接離する可動接点で、弾性変形可能な導電金属薄板製の可動板部14Aと、この両端に固着された略ドーム状の接点部14Bから形成されている。
【0025】
また、18は導電金属板製の支持体、15はコイル状の接圧ばねで、ケース11の内底面との間にやや撓んだ状態で装着された接圧ばね15によって、支持体18中央の凸状の支持部18Aが可動接点14を押圧し、上方の固定接点13方向に付勢している。
【0026】
そして、この付勢力によって可動接点14の可動板部14A両端部が弾性変形して、接点部14Bの中央側端部が固定接点13の接点部13Bの中央側端部に弾接すると共に、可動接点14の下面両端が支持体18の両端近傍に当接して、可動接点14両端部の変形量が所定の状態に保持され、複数の固定接点13が可動接点14によって、電気的に接続されてスイッチ接点が形成されている。
【0027】
なお、可動板部14A中央の両側に下方に突出した係止部が、支持体18中央の切欠きに係合して、可動接点14が支持体18に対して回転しないように係止されている。
【0028】
また、16はコイル状の戻りばね、17はケース11上面の開口部を覆うカバーで、戻りばね16が接圧ばね15や、支持体18中央の孔18B及び可動接点14中央の孔14Cを挿通して、作動体12下面とケース11底面との間にやや撓んだ状態で装着され、作動体12を上方に付勢すると共に、カバー17の中空筒部17A内に差動体12の操作軸12Aが上下動可能に挿通し、操作軸12A上端が中空筒部17Aから上方へ突出して、車両用プッシュスイッチ19が構成されている。
【0029】
そして、このように構成された車両用プッシュスイッチ19は、図5の外観図に示すように、自動車のブレーキペダル9の手前に装着され、固定接点13の端子部13Aにはストップランプ(図示せず)に接続されたコネクタ10が装着される。
【0030】
また、図5に示すように、ブレーキペダル9が踏み込まれていない状態では、車両用プッシュスイッチ19はブレーキペダル9のアーム9Aによって作動体12の操作軸12Aが押圧された状態となっている。
【0031】
つまり、図3の断面図に示すように、作動体12が戻りばね15を撓めながら下方へ押圧され、作動体12下端に上面を押圧された可動接点14が、接圧ばね15を撓めながら下方へ移動して、可動接点14が固定接点13から離れ、複数の固定接点13の間が電気的に切断された状態となっているため、ストップランプは消灯している。
【0032】
そして、この状態からブレーキペダル9が踏み込まれると、アーム9Aが操作軸12Aから離れ押圧力が除かれるため、図4の断面図に示すように、作動体12が戻りばね16の弾性復帰力によって上方へ移動すると共に、可動接点14と支持体18が接圧ばね15に付勢されて上方へ移動する。
【0033】
なお、この可動接点14が上方へ移動して固定接点13に接触し、ストップランプが点灯した瞬間は、図4に示すように、可動接点14の可動板部14A両端部が真直ぐであるため、可動接点14両端の接点部14B中心部と複数の固定接点13の接点部13B中心部が当接した状態となっている。
【0034】
そして、さらに可動接点14が接圧ばね15に付勢されて上方へ移動すると、図1に示したように、可動接点14の可動板部14A両端部が弾性変形して、接点部14Bの中央側端部が固定接点13の接点部13Bの中央側端部に弾接する。
【0035】
つまり、可動接点14が固定接点13に接触した瞬間の図4の状態から、作動体12が上方へ移動し終えた図1の状態の間に、接点部14Bが接点部13B上を弾接摺動し、接触箇所が中心部から中央側端部へ変化する、所謂、接点のワイピング作用が得られるように構成されている。
【0036】
そして、この時、ストップランプに電球が用いられている場合には、DC12V10A程度の比較的大きな電圧電流が通電され、アーク放電等により接点表面に炭化物や損傷が生じるが、上記のように、可動接点14が固定接点13に接触しアーク放電等が発生する瞬間には、接点部14Bと接点部13Bは中心部同士で接触し、その後、接点ワイピングが行なわれて接触箇所が変化し、比較的炭化物の荒れの少ない中央側端部表面が弾接した状態で通電が行なわれる。
【0037】
また、ストップランプにLED等が用いられ、DC12V0.5A〜1A程度と比較的小さな電流が通電される場合には、アーク放電等は発生しない代りに、周囲の環境や経時変化等によって、接点表面に炭化被膜や酸化被膜等が生じるが、これらに対しても上記のように接点ワイピングが行なわれることによって、多少の炭化被膜や酸化被膜等は除去され、安定した状態で通電を行なうことができる。
【0038】
なお、踏み込まれたブレーキペダル9を離すと、元の位置へ付勢されたブレーキペダル9のアーム9Aによって、車両用プッシュスイッチ19の操作軸12Aが押圧され、以上の説明とは逆の動作が行なわれ、図3の状態に戻ってストップランプが消灯するように構成されている。
【0039】
このように本実施の形態によれば、接圧ばね15に付勢された可動接点14が固定接点13に弾接した時に、この可動接点14の両端部を弾性変形させることによって、可動接点14と固定接点13が接離する際に接触箇所が変化する、所謂、接点のワイピング作用が得られるため、簡易な構成で、小電流から大電流まで幅広い範囲で接触の安定した車両用プッシュスイッチを得ることができるものである。
【0040】
そして、導電金属製の支持体18を可動接点14と接圧ばね15との間に配置すると共に、可動接点14が固定接点13に弾接した時、可動接点14の両端を支持体18に当接させることによって、可動接点14両端部の変形量を所定の状態に保つことができると共に、可動接点14に加え支持体18も導体として通電されるため、さらに安定した接触を得ることができる。
【0041】
また、以上の説明では、作動体12の下方への移動によって、可動接点14が固定接点13から離れる構成について説明したが、これとは逆に、作動体12の下方への移動により可動接点14が固定接点13に接触する構成等、様々な構成のプッシュスイッチにおいても、本発明の実施は可能である。
【0042】
【発明の効果】
以上のように、本発明によれば、簡易な構成で、小電流から大電流まで幅広い範囲で接触の安定した車両用プッシュスイッチを実現することができるという有利な効果が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle push switch mainly used for turning on / off a stop lamp when operating a brake pedal of an automobile.
[0002]
[Prior art]
In recent years, push operation type push switches for vehicles have been widely used to control the stop lamp accompanying the operation of the brake pedal, turning on the stop lamp when depressing the brake pedal and turning it off when releasing the brake pedal. I have.
[0003]
Such a conventional push switch for a vehicle will be described with reference to FIGS.
[0004]

[0005]
Reference numeral 4 denotes a movable contact made of a conductive metal. The movable contact 4 elastically contacts the plurality of fixed contacts 3 from below by a contact pressure spring 5 mounted between the movable contact 4 and the bottom surface of the case 1 in a slightly bent state. , A plurality of fixed contacts 3 are electrically connected by a movable contact 4 to form a switch contact.
[0006]
Reference numeral 6 denotes a coil-shaped return spring. Reference numeral 7 denotes a cover that covers an opening on the upper surface of the case 1. The return spring 6 is mounted in a slightly bent state between the lower surface of the operating body 2 and the bottom surface of the case 1. The operating body 2 is urged upward.
[0007]
Further, the cover 7 is provided with a hollow cylindrical portion 7A that protrudes upward. The operating shaft 2A of the operating body 2 is vertically movably inserted into the hollow cylindrical portion 7A, and the upper end of the operating shaft 2A is a hollow cylindrical portion 7A. , A push switch 8 for a vehicle is formed.
[0008]
In the above configuration, when the operating body 2 is urged by the return spring 6 and is held upward, that is, in a so-called release state, when the upper end of the operation shaft 2A is pressed downward, as shown in the sectional view of FIG. As shown, the operating body 2 moves downward while bending the return spring 6, and the movable contact 4 whose upper surface is pressed by the lower end of the operating body 2 moves downward while bending the contact pressure spring 5, Since the fixed contacts 3 are separated from each other, the plurality of fixed contacts 3 are electrically disconnected.
[0009]
Then, when the pressing force to the operation shaft 2A is removed, the operating body 2 moves upward by the elastic return force of the return spring 6, and the movable contact 4 is also pressed by the contact pressure spring 5 to elastically contact the fixed contact 3, The state returns to the release state in FIG. 6 in which the plurality of fixed contacts 3 are electrically connected.

[Problems to be solved by the invention]
However, in the above-described conventional vehicle push switch, when a large current is applied, carbide or damage occurs on the contact surface due to arc discharge or the like at the time of contact and separation, and when a small current is applied, Although a carbonized film or an oxide film is formed on the contact surface, since the movable contact 4 and the fixed contact 3 are always in contact at the same place, there has been a problem that the contact tends to be unstable due to these.
[0017]
An object of the present invention is to solve such a conventional problem and to provide a push switch for a vehicle that can be used in a wide range from a small current to a large current and that can achieve stable contact. It is assumed that.
[0018]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration.
[0019]
According to the first aspect of the present invention, when a movable contact biased by a spring resiliently contacts a fixed contact, both ends of the movable contact are elastically deformed to constitute a push switch for a vehicle. The contact point changes when the movable contact and the fixed contact come and go by the elastic deformation of both ends of the movable contact, so-called wiping action of the contact can be obtained. This has the effect that a push switch for vehicles with stable contact can be obtained in a wide range up to a wide range.
[0020]
According to a second aspect of the present invention, in the first aspect of the present invention, the conductive metal support is disposed between the movable contact and the spring, and the movable contact is elastically contacted with the fixed contact. Both ends of the contact are brought into contact with the support, and the amount of deformation at both ends of the movable contact can be kept in a predetermined state.In addition to the movable contact, the support is also energized as a conductor, so it is more stable. It has the effect that contact can be obtained.
[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5.
[0022]
The same components as those described in the section of the related art are denoted by the same reference numerals, and detailed description will be simplified.
[0023]
(Embodiment)
FIG. 1 is a sectional view of a push switch for a vehicle according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the push switch, and in FIG. A plurality of fixed contacts 13 which are substantially columnar and also made of an insulating resin, have a case 11 on which a terminal portion 13A protrudes from the bottom surface and a substantially dome-shaped contact portion 13B is formed on both sides of the operating body 12. It has been planted.
[0024]
Reference numeral 14 denotes a movable contact whose both ends contact and separate from the fixed contact 13. The movable contact 14 is formed of a movable plate portion 14A made of an elastically deformable conductive metal plate and a substantially dome-shaped contact portion 14B fixed to both ends. I have.
[0025]
Reference numeral 18 denotes a support made of a conductive metal plate, and reference numeral 15 denotes a coil-shaped contact pressure spring. The contact pressure spring 15 attached between the inner bottom surface of the case 11 and the support 18 is slightly bent. The convex support portion 18A presses the movable contact 14 and urges it toward the upper fixed contact 13.
[0026]
Then, both ends of the movable plate portion 14A of the movable contact 14 are elastically deformed by the biasing force, so that the central end of the contact portion 14B elastically contacts the central end of the contact portion 13B of the fixed contact 13, and the movable contact Both ends of the lower surface of the support 14 are in contact with the vicinity of both ends of the support 18, the amount of deformation of both ends of the movable contact 14 is maintained in a predetermined state, and the plurality of fixed contacts 13 are electrically connected by the movable contact 14 to switch the switch. Contacts are formed.
[0027]
The locking portions projecting downward on both sides of the center of the movable plate portion 14A engage with the notches in the center of the support 18 so that the movable contact 14 is locked so as not to rotate with respect to the support 18. I have.
[0028]
Reference numeral 16 denotes a coil-shaped return spring. Reference numeral 17 denotes a cover that covers an opening on the upper surface of the case 11. The return spring 16 passes through the contact pressure spring 15, the hole 18B in the center of the support member 18, and the hole 14C in the center of the movable contact 14. The operation body 12 is mounted in a slightly bent state between the lower surface of the operation body 12 and the bottom surface of the case 11, and urges the operation body 12 upward. The push switch 19 for a vehicle is configured such that the upper end of the operation shaft 12A protrudes upward from the hollow cylindrical portion 17A.
[0029]
The push switch 19 for a vehicle configured as described above is mounted in front of the brake pedal 9 of the vehicle as shown in the external view of FIG. 5, and a terminal 13A of the fixed contact 13 has a stop lamp (not shown). ) Is mounted.
[0030]
As shown in FIG. 5, when the brake pedal 9 is not depressed, the vehicle push switch 19 is in a state where the operating shaft 12A of the operating body 12 is pressed by the arm 9A of the brake pedal 9.
[0031]
That is, as shown in the cross-sectional view of FIG. 3, the operating body 12 is pressed downward while bending the return spring 15, and the movable contact 14 whose upper surface is pressed at the lower end of the operating body 12 deflects the contact pressure spring 15. The stop lamp is turned off because the movable contact 14 moves downward while moving away from the fixed contact 13 and the plurality of fixed contacts 13 are electrically disconnected.
[0032]
Then, when the brake pedal 9 is depressed from this state, the arm 9A separates from the operation shaft 12A and the pressing force is removed, and as shown in the cross-sectional view of FIG. While moving upward, the movable contact 14 and the support 18 are urged by the contact pressure spring 15 to move upward.
[0033]
At the moment when the movable contact 14 moves upward and contacts the fixed contact 13 and the stop lamp is turned on, as shown in FIG. 4, both ends of the movable plate 14A of the movable contact 14 are straight. The central portions of the contact portions 14B at both ends of the movable contact 14 and the central portions of the contact portions 13B of the plurality of fixed contacts 13 are in contact with each other.
[0034]
When the movable contact 14 is further urged by the contact pressure spring 15 to move upward, as shown in FIG. 1, both ends of the movable plate 14A of the movable contact 14 are elastically deformed, and the center of the contact 14B is moved. The side end portion elastically contacts the center end portion of the contact portion 13B of the fixed contact 13.
[0035]
That is, the contact portion 14B elastically slides on the contact portion 13B from the state in FIG. 4 at the moment when the movable contact 14 contacts the fixed contact 13 to the state in FIG. 1 in which the operating body 12 has finished moving upward. It moves so that the contact point changes from the center to the center end, so-called wiping action of the contact is obtained.
[0036]
At this time, when a light bulb is used as the stop lamp, a relatively large voltage current of about DC12V10A is applied to cause carbide or damage to the contact surface due to arc discharge or the like. At the moment when the contact 14 comes into contact with the fixed contact 13 and an arc discharge or the like occurs, the contact portion 14B and the contact portion 13B come into contact with each other at a central portion, and thereafter, contact wiping is performed to change the contact location, and The energization is performed in a state in which the surface of the central end portion where the roughness of the carbide is small is in elastic contact.
[0037]
When an LED or the like is used as a stop lamp and a relatively small current of about 12 V DC 0.5 A to 1 A is applied, an arc discharge or the like does not occur, but the contact surface is changed due to the surrounding environment or a change with time. A carbonized film, an oxide film, and the like are formed on the surface, and the contact wiping is also performed on these to remove a small amount of the carbonized film, the oxide film, and the like, so that current can be supplied in a stable state. .
[0038]
When the brake pedal 9 is released, the operation shaft 12A of the vehicle push switch 19 is pressed by the arm 9A of the brake pedal 9 urged to the original position, and the operation reverse to the above description is performed. Then, the operation returns to the state of FIG. 3 and the stop lamp is turned off.
[0039]
As described above, according to the present embodiment, when the movable contact 14 urged by the contact pressure spring 15 resiliently contacts the fixed contact 13, the movable contact 14 is elastically deformed at both ends thereof. Since the so-called wiping action of the contact is obtained when the contact point changes when the fixed contact 13 comes and goes, a push switch for a vehicle with a simple configuration and stable contact in a wide range from a small current to a large current can be provided. What you can get.
[0040]
A support 18 made of conductive metal is arranged between the movable contact 14 and the contact pressure spring 15, and when the movable contact 14 resiliently contacts the fixed contact 13, both ends of the movable contact 14 contact the support 18. By making contact, the amount of deformation at both ends of the movable contact 14 can be maintained in a predetermined state, and the support 18 as well as the conductor is energized as a conductor, so that more stable contact can be obtained.
[0041]
Further, in the above description, the configuration in which the movable contact 14 is separated from the fixed contact 13 by the downward movement of the operating body 12 has been described. Conversely, the movable contact 14 is downwardly moved by the downward movement of the operating body 12. The present invention is also applicable to push switches having various configurations, such as a configuration in which the switch contacts the fixed contact 13.
[0042]
【The invention's effect】
As described above, according to the present invention, it is possible to obtain an advantageous effect that a push switch for a vehicle can be realized with a simple configuration and a stable contact in a wide range from a small current to a large current.
