Description

【0001】
【発明の属する技術分野】
本発明は、ハンドルを操作することにより出力端子を左右いずれかの側に切り換える切換スイッチに関するものである。
【0002】
【従来の技術】
上記のような切換スイッチとしては、図7に示すようにケース50に軸51で枢着されたハンドル52の下端に一枚板からなる可動接触子53を設けたものが普通であった。この可動接触子53と軸51との間には反転ばね54が設けられており、可動接触子53をその上端を折曲点としたくの字状に引いている。可動接触子53の下端は二股状として、第1の可動接点55と第2の可動接点56とが形成されている。
【0003】
図7に示した状態では、可動接触子53は反転ばね54により右側に引かれ、ケース50の下部に設けられた第1の固定接点57に第1の可動接点55が接触している。またケース50の片側に設けられたコモン端子58と可動接触子53との間は、縒り線等からなる可撓導線59で接続されている。このため図7の状態ではコモン端子58は右側の第1の固定接点57に接続され、出力端子は右側となる。
【0004】
しかしハンドル52を左方向に操作すると、反転ばね54は次第に引き伸ばされ、軸51と可動接触子53の上端と反転ばね54の下端とが一直線となる中立点を越えると、反転ばね54の力により可動接触子53とハンドル52は一気に反対側にくの字状に引かれる。そして可動接触子53の下端の第2の可動接点56がケース50の下部の第2の固定接点60に接触し、出力端子は左側に切り換わる。
【0005】
従来の切換スイッチは上記のように構成されているため、第1の可動接点55と第2の可動接点56との距離は接近している。そのため、第1の可動接点55が開くときに第1の固定接点57との間で発生するアークが第2の可動接点56に影響し、アークによって発生した不純物が第2の可動接点56に付着して導通不良を招いたり、接点の磨耗を早める原因となっていた。
【0006】
また従来の切換スイッチは、反転ばね54により可動接触子53とハンドル52とを左右いずれかの方向にくの字状に引く構造となっているため、可動接触子53は必ず第1の固定接点57又は第2の固定接点60に接触した状態を取る。このため切換スイッチを中立位置に維持することは不可能であった。
【0007】
【発明が解決しようとする課題】
本発明は上記した従来の問題点を解決し、接点開放時に発生するアークが他方の接点に影響することがなく、またハンドルを中立位置に維持することができる切換スイッチを提供するためになされたものである。
【0008】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の切換スイッチは、左右に固定接点を備えたケースに、左右方向に操作されるハンドルをその上端と下端との中間に設けられた軸により枢着し、このハンドルの下端の左右両側にそれぞれピンを突設し、これらのピンに左右の可動接触子の上端部を嵌め込むとともに、各可動接触子の中間位置とハンドルの軸との間に中立点を越えた瞬間に可動接触子を反転させる反転ばねをそれぞれ張設してハンドルの操作方向の可動接触子を左右の固定接点側に動作させる構造とし、またケースの中央部側壁に開状態にある各可動接触子の背面が当接される中央突起を突設するとともに、ハンドルを片側に操作したときに非動作側の可動接触子の上部と係合して可動接触子をオフ位置に留めるための動作規制部を形成し、かつコモン端子をケース内でハンドルの左側から右側まで延ばし、可撓導線で左右の各可動接触子と接続したことを特徴とするものである。
【0009】
本発明の切換スイッチは、2つの個別の可動接触子を備えたものであるため、両者間の距離を大きく取ることができ、アークに影響されることがない。またハンドルに中立位置を取らせることができ、左右いずれの側にも出力しない状態に維持することができる。
【0010】
【発明の実施の形態】
以下に本発明の好ましい実施形態を示す。
図1において、1は左右に固定接点12,11を備えたケース、2は軸3によりこのケース1内に枢着され左右方向に操作されるハンドルである。ハンドル2の下端には左右両側にピン4、4が突設されており、これらのピン4、4に2つの個別の可動接触子5、5の上端の逆U字状部6、6が嵌め込まれている。各可動接触子5、5の中間位置と軸3との間には、それぞれ反転ばね7、7が張設されている。
【0011】
図1に示す状態では、各反転ばね7、7は各可動接触子5、5を中心側にくの字状に引いており、ケース1の中央部側壁に形成された中央突起8に各可動接触子5、5の背面が当たっている。各可動接触子5、5の下部にはそれぞれ第1の可動接点9と第2の可動接点10とが形成されており、ケース1の内部の左右両側に設けられた第1の固定接点11と第2の固定接点12とに対向させてある。図1に示す状態では、各可動接触子5、5は中心側に引かれているから、第1の可動接点9と第2の可動接点10は、何れも第1の固定接点11と第2の固定接点12とから離れたオフ位置にある。従ってこの状態ではハンドル2は安定した中立位置を取ることとなる。
【0012】
なお13はコモン端子であり、図2に示すようにケース1に固定されている。上記したように、本発明の切換スイッチはハンドル2の下端の左右両側に2つの個別の可動接触子5、5を設けたものであるため、このコモン端子13を図2に示すようにケース1の内部でハンドル2の左側から右側まで延ばし、可撓導線14、14で各可動接触子5、5と接続してある。このような構造としたことにより可撓導線14、14が切れることが防止できる。図1の状態では、このコモン端子13は左右いずれの出力端子15、15にも接続されていない。
【0013】
図3と図4は、右側の反転ばね7等を省略して簡素化した図である。図3の中立状態からハンドル2を図4のように左側に倒して行くと、軸3とピン4と反転ばね7の下端とが一直線になった中立点を越えた瞬間に反転ばね7の力により図4のように左側の可動接触子5が外側(左側)にくの字状に引かれ、第2の可動接点10が第2の固定接点12と接触する。この状態では、コモン端子13は左側の出力端子15に接続される。
【0014】
このようにしてハンドル2を中立状態から左右いずれかの側に操作すると、それに連れて出力端子15、15の切り換えが可能となる。左右の可動接触子5、5は独立しているため、それぞれの下端に設けられた第1の可動接点9と第2の可動接点10との距離を十分に取ることができる。従って従来のように接点開放時に発生するアークが他方の接点に影響することを防止できる。
【0015】
またこの実施形態では、ハンドル2を一方に倒したときにも他方(右側)の可動接触子5は図4のように元のままのオフ位置に留まるようにしてある。その理由及びそのための機構を、図5と図6により説明する。
図6はハンドル2の下端に単に2つの個別の可動接触子5、5を設けた場合の問題点を示す図であり、中立状態からハンドル2を左側に倒して行くと、右側の可動接触子5の上端を支持しているハンドル2のピン4も軸3を中心とする円弧を描きながら右上方に移動する。このため右側の可動接触子5はそれに連れて移動し、図示のように第1の可動接点9はオフ位置よりも第1の固定接点11に接近する。また、右側の可動接触子5は中央突起8から離れるまではハンドル2の反時計方向の回転モーメントを与えるが、図面上左側に倒れているハンドル2を反対側に動作させる時にハンドル2が完全に中立位置になるまでに手を外してしまうと、右側の可動接触子5と右側の反転ばね7とのモーメントと、左側の可動接触子5と左側の反転ばね7とのモーメントとでは、右側の可動接触子5のモーメントの方が強い。言い換えれば反転ばね7と可動接触子5との角度が小さい。このように左側の可動接触子5より右側の可動接触子5のモーメントの方が強いとハンドル2が左側に戻ってしまう。また左側にあるハンドル2を反対側に動作させるときに、ハンドル2が中立位置まできた際に少しでも勢いがあると右側の可動接触子5と右側の反転ばね7とのモーメントと左側の可動接触子5と左側の反転ばね7とのモーメントとでは、左側の可動接触子5のモーメントの方が強いため、一挙にハンドル2が右側に倒れてしまう。このようにハンドル2を中立位置で止めることはできなかった。
【0016】
そこでこの実施形態では図5に示すように、ハンドル2を片側に操作したときに非動作側の可動接触子5をオフ位置に留めるための動作規制部16を、ケース1の側壁に形成してある。この動作規制部16は非動作側の可動接触子5が図6のように上方に移動することを防止し、図5のように非動作側の可動接触子5のモーメントがハンドル2に伝わらないように、可動接触子5の上部の逆U字状部6とハンドル2の突起と切り離すようにするため、各可動接触子5の上部側面の円形突起17を上から押さえることができる形状となっている。またこの動作規制部16は、ハンドル2を片側に操作したときに動作側の可動接触子5の動きを妨げるものであってはならない。また、上部に膨らんだ位置で非動作側の可動接触子5が止まるようにしてあり、動作規制部16は両側が上部に膨らんだ左右対称形状となっている。
【0017】
このような動作規制部16によって、図5に示すようにハンドル2を片側に操作したときに非動作側の可動接触子5をオフ位置に留めたままとしておけば、図6について説明したように可動接点が固定接点に接近することがなくなり、またハンドル荷重に変動が生じず中立位置で止めることができる。
【0018】
このような動作規制部16の本来の役割からは、図示のように動作規制部16をループ状に形成する必要はなく、上半部のみで足りることとなる。しかし図示のようにループ状としておけば、衝撃や輸送時の振動等によって可動接触子5がハンドル2のピン4から外れることを防止できる副次的な効果が得られる。なおこの実施形態では動作規制部16をケース1の側壁に形成したが、ケース1とは別に形成しても差し支えない。
【0019】
またこの実施形態では、図4に示すようにハンドル2が操作されたときの受部18を、ケース1の内壁部に設けてある。従来は図7に示すように、ケース50のハンドル開口部61でハンドル52を受けていたが、ハンドル操作によりこの部分に傷が付いて見苦しくなる。これに対してこの実施形態のように受部18をケース1の内壁部に設ければ、ハンドル開口部には傷が付かない利点がある。
【0020】
【発明の効果】
以上に説明したように、本発明の切換スイッチはハンドルの下端の左右両側に2つの個別の可動接触子を設けたものであり、接点開放時に発生するアークが他方の接点に影響することがなく、またハンドルを中立位置に維持することができる利点がある。また動作規制部を設けることにより、非動作の可動接点が固定接点に接近することがなくなり、またハンドル荷重に変動が生じず、中立位置で止めることができる。またコモン端子をケース内でハンドルの左側から右側まで延ばすことにより、可撓導線の切れを防止できる。更にハンドルの受部をケースの内壁部に設けることにより、ハンドル開口部の傷をなくすことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a changeover switch that switches an output terminal to either the left or right side by operating a handle.
[0002]
[Prior art]
As the change-over switch as described above, a switch having a movable contact 53 made of a single plate is usually provided at the lower end of a handle 52 pivotally attached to a case 50 by a shaft 51 as shown in FIG. A reversing spring 54 is provided between the movable contact 53 and the shaft 51, and the movable contact 53 is drawn in a square shape with its upper end as a bending point. The lower end of the movable contact 53 is bifurcated, and a first movable contact 55 and a second movable contact 56 are formed.
[0003]
In the state shown in FIG. 7, the movable contact 53 is pulled to the right by the reversing spring 54, and the first movable contact 55 is in contact with the first fixed contact 57 provided at the lower part of the case 50. Further, the common terminal 58 provided on one side of the case 50 and the movable contact 53 are connected by a flexible conductive wire 59 made of a twisted wire or the like. Therefore, in the state of FIG. 7, the common terminal 58 is connected to the first fixed contact 57 on the right side, and the output terminal is on the right side.
[0004]
However, when the handle 52 is operated to the left, the reversing spring 54 is gradually stretched, and when the shaft 51, the upper end of the movable contact 53 and the lower end of the reversing spring 54 exceed a neutral point, the force of the reversing spring 54 The movable contact 53 and the handle 52 are pulled in a dogleg shape at the opposite side. Then, the second movable contact 56 at the lower end of the movable contact 53 comes into contact with the second fixed contact 60 below the case 50, and the output terminal is switched to the left side.
[0005]
Since the conventional changeover switch is configured as described above, the distance between the first movable contact 55 and the second movable contact 56 is close. Therefore, an arc generated between the first movable contact 55 and the first fixed contact 57 when the first movable contact 55 opens affects the second movable contact 56, and impurities generated by the arc adhere to the second movable contact 56. As a result, poor continuity is caused and contact wear is accelerated.
[0006]
In addition, since the conventional changeover switch has a structure in which the movable contact 53 and the handle 52 are pulled in a left-right direction by the reversing spring 54, the movable contact 53 is always the first fixed contact. 57 or the second fixed contact 60 is brought into contact. For this reason, it was impossible to maintain the changeover switch in the neutral position.
[0007]
[Problems to be solved by the invention]
The present invention has been made in order to solve the above-described conventional problems and to provide a change-over switch capable of maintaining the handle in a neutral position without causing an arc generated when the contact is opened to affect the other contact. Is.
[0008]
[Means for Solving the Problems]
The changeover switch of the present invention, which has been made to solve the above problem, is pivotally attached to a case having a fixed contact on the left and right by a shaft provided in the middle between its upper and lower ends. and, projecting each pin on the left and right sides of the lower end of the handle, with fitting the upper end portion of the movable contact of the left and right of these pins, neutral between the shaft of the intermediate position and the handle of the movable contact a structure that respectively stretched the reversing spring to be inverted to operate the operation direction of the movable contact of the handle to the left and right stationary contact side of the movable contactor at the moment beyond the point, also in the open state in the center portion side wall of the case A central projection is formed to contact the back of each movable contact, and when the handle is operated to one side, it engages with the upper part of the non-operating movable contact to keep the movable contact in the off position. Operation regulation part for Formed, and extends from the left side of the handle common terminal in the case to the right, it is characterized in that connected to each of the movable contact of the left and right flexible conductor.
[0009]
Since the changeover switch of the present invention is provided with two individual movable contacts, the distance between the two can be increased and the arc is not affected. In addition, the handle can be in a neutral position and can be maintained in a state in which it is not output to either the left or right side.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention are shown below.
In FIG. 1, 1 is a case provided with fixed contacts 12 and 11 on the left and right, and 2 is a handle that is pivotally mounted in the case 1 by a shaft 3 and is operated in the left-right direction . Pins 4, 4 protrude from the lower end of the handle 2 on the left and right sides, and inverted U-shaped portions 6, 6 at the upper ends of two individual movable contacts 5, 5 are fitted into these pins 4, 4. It is. Reversing springs 7 and 7 are respectively stretched between the intermediate positions of the movable contacts 5 and 5 and the shaft 3.
[0011]
In the state shown in FIG. 1, each reversing spring 7, 7 pulls each movable contact 5, 5 in the shape of a circle toward the center, and each movable spring is moved to a central protrusion 8 formed on the central side wall of case 1. The back surfaces of the contacts 5 and 5 are in contact. A first movable contact 9 and a second movable contact 10 are formed at the lower part of each movable contact 5, 5, and the first fixed contact 11 provided on the left and right sides inside the case 1 It is opposed to the second fixed contact 12. In the state shown in FIG. 1, since each movable contact 5 and 5 is pulled to the center side, the first movable contact 9 and the second movable contact 10 are both the first fixed contact 11 and the second movable contact 10. It is in an off position away from the fixed contact 12. Therefore, in this state, the handle 2 takes a stable neutral position.
[0012]
Reference numeral 13 denotes a common terminal, which is fixed to the case 1 as shown in FIG. As described above, since the change-over switch of the present invention is provided with the two individual movable contacts 5 and 5 on the left and right sides of the lower end of the handle 2, the common terminal 13 is connected to the case 1 as shown in FIG. Is extended from the left side to the right side of the handle 2 and is connected to the movable contacts 5 and 5 by flexible conductive wires 14 and 14. By adopting such a structure, it is possible to prevent the flexible conductive wires 14 and 14 from being cut. In the state of FIG. 1, the common terminal 13 is not connected to any of the left and right output terminals 15 and 15.
[0013]
3 and 4 are simplified diagrams in which the right reversing spring 7 and the like are omitted. When the handle 2 is tilted to the left as shown in FIG. 4 from the neutral state of FIG. 3, the force of the reversing spring 7 at the moment when the shaft 3, the pin 4 and the lower end of the reversing spring 7 are over the neutral point. As a result, the left movable contact 5 is pulled outward (left) in a U-shape as shown in FIG. 4, and the second movable contact 10 comes into contact with the second fixed contact 12. In this state, the common terminal 13 is connected to the left output terminal 15.
[0014]
When the handle 2 is operated from the neutral state to the left or right side in this manner, the output terminals 15 and 15 can be switched accordingly. Since the left and right movable contacts 5 and 5 are independent, a sufficient distance can be obtained between the first movable contact 9 and the second movable contact 10 provided at the lower ends of the respective contacts. Therefore, it is possible to prevent the arc generated when the contact is opened from affecting the other contact as in the prior art.
[0015]
Further, in this embodiment, even when the handle 2 is tilted to one side, the other (right side) movable contact 5 remains in the original off position as shown in FIG. The reason and the mechanism for this will be described with reference to FIGS.
FIG. 6 is a diagram showing a problem when the two individual movable contacts 5 and 5 are simply provided at the lower end of the handle 2. When the handle 2 is tilted to the left from the neutral state, the right movable contact is shown. The pin 4 of the handle 2 supporting the upper end of 5 also moves to the upper right while drawing an arc centered on the axis 3. Therefore, the right movable contact 5 moves accordingly, and the first movable contact 9 is closer to the first fixed contact 11 than the OFF position as shown in the figure. Further, the movable contact 5 on the right side gives a counterclockwise rotational moment of the handle 2 until it moves away from the central protrusion 8, but the handle 2 is completely moved when the handle 2 that is tilted to the left in the drawing is moved to the opposite side. If the hand is removed before reaching the neutral position, the moment of the right movable contact 5 and the right reversing spring 7 and the moment of the left movable contact 5 and the left reversing spring 7 are The moment of the movable contact 5 is stronger. In other words, the angle between the reversing spring 7 and the movable contact 5 is small. As described above, when the moment of the right movable contact 5 is stronger than that of the left movable contact 5, the handle 2 returns to the left side. Also, when the handle 2 on the left side is moved to the opposite side, if there is any momentum when the handle 2 reaches the neutral position, the moment between the right movable contact 5 and the right reversing spring 7 and the left movable contact Since the moment of the left movable contact 5 is stronger than the moment of the child 5 and the left reversing spring 7, the handle 2 falls to the right at once. Thus, the handle 2 could not be stopped at the neutral position.
[0016]
Therefore, in this embodiment, as shown in FIG. 5, an operation restricting portion 16 is formed on the side wall of the case 1 to keep the non-operation side movable contactor 5 in the off position when the handle 2 is operated to one side. is there. The operation restricting portion 16 prevents the non-operating side movable contact 5 from moving upward as shown in FIG. 6, and the moment of the non-operating side movable contact 5 is not transmitted to the handle 2 as shown in FIG. Thus, in order to separate the inverted U-shaped portion 6 at the top of the movable contact 5 from the protrusion of the handle 2, the circular protrusion 17 on the upper side surface of each movable contact 5 can be pressed from above. ing. Further, the operation restricting portion 16 should not hinder the movement of the movable contact 5 on the operation side when the handle 2 is operated to one side. Further, the movable contact 5 on the non-operation side stops at a position swelled upward, and the operation restricting portion 16 has a bilaterally symmetric shape with both sides swelled upward.
[0017]
As described with reference to FIG. 6, if the operation restricting portion 16 keeps the non-operating movable contact 5 in the off position when the handle 2 is operated to one side as shown in FIG. The movable contact does not approach the fixed contact, and the handle load does not vary and can be stopped at the neutral position.
[0018]
From the original role of the operation restricting portion 16 as described above, it is not necessary to form the operation restricting portion 16 in a loop shape as shown in the figure, and only the upper half portion is sufficient. However, if it is formed in a loop shape as shown in the figure, a secondary effect can be obtained in which the movable contact 5 can be prevented from being detached from the pin 4 of the handle 2 due to impact or vibration during transportation. In this embodiment, the operation restricting portion 16 is formed on the side wall of the case 1, but it may be formed separately from the case 1.
[0019]
In this embodiment, as shown in FIG. 4, the receiving portion 18 when the handle 2 is operated is provided on the inner wall portion of the case 1. Conventionally, as shown in FIG. 7, the handle 52 is received by the handle opening 61 of the case 50, but this portion is scratched by the operation of the handle and becomes unsightly. On the other hand, if the receiving portion 18 is provided on the inner wall portion of the case 1 as in this embodiment, there is an advantage that the handle opening is not damaged.
[0020]
【The invention's effect】
As described above, the changeover switch of the present invention is provided with two individual movable contacts on the left and right sides of the lower end of the handle, and the arc generated when the contact is opened does not affect the other contact. There is also an advantage that the handle can be maintained in a neutral position. Further, by providing the operation restricting portion, the non-operating movable contact does not approach the fixed contact, and the handle load does not change and can be stopped at the neutral position. Further, by extending the common terminal from the left side to the right side of the handle in the case, it is possible to prevent the flexible conductive wire from being cut. Further, by providing the handle receiving portion on the inner wall portion of the case, it is possible to eliminate damage to the handle opening.
