Description

この発明は、固定接点および可動接点を接離させることにより電気回路を切り替えるレバースイッチに関する。   The present invention relates to a lever switch that switches an electric circuit by moving a fixed contact and a movable contact.

レバースイッチは、スイッチ本体に固定されている導電体でなる固定接点に対し、操作体を傾動または上下動させて同じく導電体からなる可動接点を接離させ、固定接点と可動接点を導通させるものであり、複数固定されてなる固定接点に可動接点を選択的に接離させることにより電気回路を切り替えるものである。   The lever switch makes the fixed contact and the movable contact conductive by moving the operating body tilting or moving up and down and moving the movable contact made of the same conductor to and away from the fixed contact made of the conductor fixed to the switch body. The electric circuit is switched by selectively bringing a movable contact into and out of a plurality of fixed contacts.

例えば、スイッチケースの内底面に複数の固定接点を列設し、これら固定接点の上面に接離自在に可動接点が配される。可動接点は、底辺を上方に他の二辺が弾性脚部となって下方で交差する略逆二等辺三角形状でなる可動接点体の弾性脚部の先端に配されている。   For example, a plurality of fixed contacts are arranged on the inner bottom surface of the switch case, and movable contacts are arranged on the upper surfaces of the fixed contacts so as to be freely contacted and separated. The movable contact is arranged at the tip of the elastic leg portion of the movable contact body having a substantially inverted isosceles triangle shape with the bottom side up and the other two sides as elastic leg portions and intersecting below.

この可動接点体の底辺部分には、傾動および上下動自在の操作体が浮遊状態で当接している。操作体の当接部分には、傾動方向に押圧部が列設されていて、操作体は、この押圧部を当接部分として浮遊状態で当接している。   An operation body that can be tilted and moved up and down is in contact with the bottom of the movable contact body in a floating state. At the contact portion of the operating body, pressing portions are arranged in the tilting direction, and the operating body is in contact in a floating state with the pressing portion as the contacting portion.

スイッチケースの上面には、スイッチカバーが覆設されており、スイッチカバーには、操作体の傾動方向に広幅になった開口部が設けられ、この開口部から操作体が突出している(例えば、特許文献1参照)。   A switch cover is covered on the upper surface of the switch case, and the switch cover is provided with an opening that is wide in the tilting direction of the operating body, and the operating body projects from the opening (for example, Patent Document 1).

このようにレバースイッチは、固定接点の上方に可動接点体を配し、可動接点体の上方に押圧部を配し、押圧部の上方に操作体が位置するように構成されており、操作体と押圧部および導電体が一直線に構成されている。   As described above, the lever switch is configured such that the movable contact body is disposed above the fixed contact, the pressing portion is disposed above the movable contact body, and the operating body is positioned above the pressing portion. The pressing portion and the conductor are configured in a straight line.

操作体の傾動動作のため、開口部と操作体の周囲には所定の空隙が確保されており、このようなレバースイッチは、スイッチケース内部と外気が常に通気している状態となる。特に、操作体の傾動動作時には、操作体および押圧部とスイッチケースとの間に大きな空隙が生じ、スイッチケース内部と外気が直接通気される。   Due to the tilting motion of the operating body, a predetermined gap is secured around the opening and the operating body, and such a lever switch is in a state where the inside of the switch case and the outside air are always ventilated. In particular, during the tilting operation of the operating body, a large gap is generated between the operating body and the pressing portion and the switch case, and the inside of the switch case and the outside air are directly ventilated.

したがって、スイッチケース内部の固定接点や可動接点体といった金属で形成された導電体は、常時外気にさらされ、特に傾動または上下動作時には直接外気にさらされることとなる。   Therefore, a conductor made of metal such as a fixed contact or a movable contact body inside the switch case is always exposed to the outside air, and is directly exposed to the outside air particularly when tilting or moving up and down.

特開平11−260201号公報 (図3、図8、図10)Japanese Patent Laid-Open No. 11-260201 (FIGS. 3, 8, and 10)

このように、従来のレバースイッチにおいては、内部に収容されている固定接点や可動接点体といった金属で形成された導電体が外気にさらされた状態となっており、これら導電体が腐食しやすく、接触不良による感度の低下のおそれがある。特に、この通気部分から液体が入り込むこともあり、ショートのおそれもある。 As described above, in the conventional lever switch, conductors formed of metal such as fixed contacts and movable contact bodies housed inside are exposed to the outside air, and these conductors are easily corroded. There is a risk that sensitivity may be reduced due to poor contact. In particular , liquid may enter from this ventilation portion, which may cause a short circuit.

この発明は、このような事情に鑑みてなされたもので、防水、耐久性に優れるレバースイッチを提供することを目的とする。 This invention is made | formed in view of such a situation, and it aims at providing the lever switch excellent in waterproofing and durability.

A partition wall that divides the chamber and the conductor housing chamber into two chambers, an opening portion of a switch cover that is perforated at a location located above the operation body housing chamber in the entire switch cover, and the operation body housing chamber The operating body is housed in the lower side and the upper side protrudes from the switch cover opening, the shaft portion of the operating body protruding from both the lower side of the operating body, the upper edge of the partition wall, and the A groove portion that is formed on an upper edge portion of the side wall of the switch case facing the partition wall, and that the shaft portion of the operation body engages and rotatably supports the shaft portion; The one end face side outer peripheral part is integrally formed and disposed in the conductor housing chamber, and comes into contact with the wall surface of the partition wall from the conductor housing chamber side, so that the shaft portion of the operating body and the A flange portion that closes a gap formed between the groove portion and the flange portion is integrally formed on the flange portion, and is disposed in the conductor housing chamber, and the operation body rotates around the shaft portion, When the operating body tilts in the rotating direction, a pressing portion that tilts integrally with the operating body, a movable contact body that is housed in the conductor housing chamber and disposed below the pressing portion, A fixed contact disposed on the inner bottom surface of the conductor housing chamber and below the movable contact body, the fixed contact comprising a common contact and two individual contacts located on both sides of the common contact, Tilt direction of the operating body The movable contact body is formed by bending an elongated metal piece into a substantially inverted triangle shape, with the bottom of the inverted triangle facing the pressing portion, and the movable contact body is arranged in a line along the line. The other two sides of the inverted triangle are formed so as to intersect on the inner bottom surface of the switch case, and both ends of the intersecting two sides are respectively in contact with the common contact as movable contacts. When the operation part is tilted, and the pressing part is tilted integrally with the operation body, one side of the bottom side part of the movable contact body is pressed by the tilting pressing part and is lowered. In conjunction with this, one of the movable contacts on both sides of the movable contact body 2 is disengaged from the common contact and reaches and contacts one of the individual contacts. Ah The

ここで、上記押圧部(媒介部は、運動の伝達の観点で、操作体と可動接点体の間にあって、中間的に操作体の運動を可動接点体に伝達する仲立ちをするものである。したがって、押圧部(媒介部は、可動接点体を自身に固定させて、可動接点を共動させるものでもよいし、可動接点体を押圧して、可動接点を移動させるものであってもよい。 Here, the pressing part ( medium part ) is located between the operating body and the movable contact body from the viewpoint of transmission of motion, and intermediates to transmit the motion of the operating body to the movable contact body in the middle. Therefore, the pressing portion ( medium portion ) may be one that fixes the movable contact body to itself and moves the movable contact together, or may be one that moves the movable contact by pressing the movable contact body. .

すなわち、本発明は、固定接点と可動接点の接離はいずれの方法であっても適用でき、固定接点が配置されている面を可動接点が摺動するものであっても、固定接点の上方にある可動接点が上下動するものであっても適用できる。   That is, the present invention can be applied to any method of contacting and separating the fixed contact and the movable contact, and even if the movable contact slides on the surface where the fixed contact is disposed, It can be applied even if the movable contact located in is moved up and down.

FIG. 3 is a view of each direction around the operating body of the lever switch according to the present invention, (a) is a side view, (b) is a bottom view, (c) is a front view, and (d). FIG.

図1(a)(b)(c)に示すように、レバースイッチ1は、スイッチケース2内に、操作体4と、媒介部たる押圧部4bと、金属で形成された導電体たる可動接点体5と、同じく金属で形成された導電体たる共通接点6aおよび個別接点6b,6cからなる固定接点を収容している。スイッチケース2は、外部側壁にフランジ2eを有し、このフランジ2eと嵌合されることでスイッチケース2の上面にスイッチカバー3が覆設されている。   As shown in FIGS. 1A, 1B, and 1C, a lever switch 1 includes a switch case 2, an operating body 4, a pressing portion 4b as a mediating portion, and a movable contact as a conductor formed of metal. The body 5 and a fixed contact made up of a common contact 6a and individual contacts 6b and 6c, which are also made of metal, are accommodated. The switch case 2 has a flange 2e on the outer side wall, and the switch cover 3 is covered on the upper surface of the switch case 2 by being fitted to the flange 2e.

操作体4は、外部の力により傾動動作されるものであり、押圧部4bは、操作体4の傾動動作と共動して操作体4の傾動を可動接点体5に媒介する媒介部である。   The operating body 4 is tilted by an external force, and the pressing portion 4 b is a mediating unit that mediates the tilting of the operating body 4 to the movable contact body 5 in cooperation with the tilting operation of the operating body 4. .

可動接点体5は、押圧部4bに押圧されることにより撓み、固定接点と接離する導電体であり、共通接点6aおよび個別接点6b,6cからなる固定接点は、可動接点体5が接離することにより、共通接点6aと個別接点6bもしくは個別接点6cが導通し、それぞれが導出している外部の電気回路を導通させるものである。   The movable contact body 5 is a conductor that bends by being pressed by the pressing portion 4b and comes in contact with and separates from the fixed contact. The fixed contact composed of the common contact 6a and the individual contacts 6b and 6c is contacted and separated by the movable contact body 5. By doing so, the common contact 6a and the individual contact 6b or the individual contact 6c are brought into conduction, and an external electric circuit derived from each is brought into conduction.

スイッチカバー3には、所定位置に開口部3aが穿設されており、この開口部4aから操作体4の上部がレバースイッチ1の外部へ突出している。この開口部3aは、スイッチカバー3を横断する長形であり、スイッチカバー3の縁部分が開口部3aにより一部掘り込まれている。開口部3aは、操作体4が傾動可能となる範囲を設定している。   The switch cover 3 is provided with an opening 3a at a predetermined position, and the upper portion of the operating body 4 protrudes outside the lever switch 1 from the opening 4a. The opening 3 a is long and crosses the switch cover 3, and a part of the edge of the switch cover 3 is dug by the opening 3 a. The opening 3a sets a range in which the operating body 4 can tilt.

操作体4は、この開口部3aの横断方向に傾動されるように、スイッチケース2に傾動自在に配されている。   The operating body 4 is tiltably arranged in the switch case 2 so as to be tilted in the transverse direction of the opening 3a.

固定接点は、導電体によりなり、スイッチケース2の内底面の一側部に露出して固定されている。この固定接点は、共通接点6aと二つの個別接点6b,6cからなり、共通接点6aを中心にして、操作体4の傾動方向に列設される。さらに共通接点6aと個別接点6b,6cは、それぞれレバースイッチ1の外部に導出している。   The fixed contact is made of a conductor and is exposed and fixed to one side of the inner bottom surface of the switch case 2. The fixed contact includes a common contact 6a and two individual contacts 6b and 6c, and is arranged in a row in the tilting direction of the operation body 4 with the common contact 6a as a center. Further, the common contact 6a and the individual contacts 6b and 6c are led out of the lever switch 1, respectively.

可動接点体5は、導電体によりなり、所定の弾性力を有するように所定幅の細長の金属片でなり、外部からの押圧により撓み自在となっている。この可動接点体5は、可動接点体底辺5aを上側にして操作体4の傾動方向に沿って配され、他の二辺が下側で交差するように折り曲げられた略逆三角形状を有しており、交差する二辺の両端がそれぞれ可動接点5b,5cとなっている。可動接点5b,5cは、操作体4の傾動方向に並ぶように交差している。   The movable contact body 5 is made of a conductor, is made of an elongated metal piece having a predetermined width so as to have a predetermined elastic force, and can be freely bent by an external pressure. This movable contact body 5 has a substantially inverted triangular shape that is arranged along the tilting direction of the operating body 4 with the bottom 5a of the movable contact body as an upper side, and is bent so that the other two sides intersect at the lower side. Both ends of the intersecting sides are movable contacts 5b and 5c, respectively. The movable contacts 5b and 5c intersect so as to line up in the tilting direction of the operating body 4.

この可動接点体5は、可動接点5b,5cで内底面の固定接点が配されている一側部に弾接して配されており、外部からの押圧力による撓みにより、可動接点5b,5cが内底面を摺動して固定接点と接離可能となっている。   The movable contact body 5 is arranged in elastic contact with one side of the movable contact 5b, 5c where the fixed contact on the inner bottom surface is disposed, and the movable contacts 5b, 5c are deformed by the external pressing force. The inner bottom surface can be slid and contacted with the fixed contact.

この可動接点5b,5cの一方が共通接点6aと接触し、他方が個別接点6bもしくは個別接点6cに接触することにより、可動接点体5を介して共通接点6aと個別接点6bもしくは個別接点6cが導通する。   One of the movable contacts 5b and 5c contacts the common contact 6a, and the other contacts the individual contact 6b or the individual contact 6c, whereby the common contact 6a and the individual contact 6b or the individual contact 6c are connected via the movable contact body 5. Conduct.

可動接点体5の可動接点体底辺5aの上面には押圧部4bが所定幅をもって接触している。この押圧部4bは、操作体4の傾動方向鉛直側に配されており、フランジ部4cと軸部4aを介して操作体4と一体に形成されている。 The pressing portion 4b is in contact with the upper surface of the movable contact body bottom 5a of the movable contact body 5 with a predetermined width. The pressing portion 4b is disposed on the vertical side of the operating body 4 in the tilt direction, and is formed integrally with the operating body 4 via the flange portion 4c and the shaft portion 4a.

軸部4aは、回転自在にスイッチケース2に係合されており、操作体4および押圧部4bを傾動自在にするものである。フランジ部4cは、傾動動作時において、操作体4および押圧部4bが傾動可能範囲限界まで傾動しても軸部4a周りの空隙を塞ぐものである。 The shaft portion 4a is rotatably engaged with the switch case 2, and makes the operating body 4 and the pressing portion 4b tiltable. The flange portion 4c closes the gap around the shaft portion 4a even when the operating body 4 and the pressing portion 4b tilt to the tiltable range limit during the tilting operation.

押圧部4bは、運動の伝達の観点では、操作体4と可動接点体5の間にあって、中間的に操作体の運動を可動接点体5に伝達する仲立ちを行う媒介部であり、本実施形態の場合は、操作体4と一体に形成されることで共動し、可動接点体5の可動接点体底辺5aを押圧し、可動接点体5を撓ませる。押圧部4bの幅は、可動接点体5を傾動方向両側から押圧でき、可動接点5bが個別接点6bまで、可動接点5cが個別接点6cまで摺動できる程度に可動接点体5を撓ませることができる幅となっている。   The pressing portion 4b is a mediating portion that is located between the operating body 4 and the movable contact body 5 in the viewpoint of motion transmission, and intermediates to transmit the motion of the operating body to the movable contact body 5 in the middle. In this case, the movable contact body 5 is integrally formed with the operation body 4 to cooperate and press the movable contact body bottom 5a of the movable contact body 5 to bend the movable contact body 5. The width of the pressing portion 4b is such that the movable contact body 5 can be pressed from both sides in the tilting direction, and the movable contact body 5 can be bent to such an extent that the movable contact 5b can slide to the individual contact 6b and the movable contact 5c to the individual contact 6c. The width is possible.

尚、この押圧部4bは、スイッチケース2の上縁から一部はみだして配されており、スイッチケース2の上面に覆設されるスイッチカバー3の内底面であって、押圧部4bが配される位置には、この押圧部4bを覆う形状で凹部3bが穿設され、押圧部4bを回転自在にしている。   The pressing portion 4b is disposed so as to partially protrude from the upper edge of the switch case 2, and is an inner bottom surface of the switch cover 3 that is covered on the upper surface of the switch case 2, and the pressing portion 4b is disposed. In this position, a recess 3b is formed so as to cover the pressing portion 4b so that the pressing portion 4b is rotatable.

このように、押圧部4bは、操作体4の傾動方向鉛直側に配され、押圧部4bの下方に可動接点体5が配され、可動接点体5の下方に共通接点6aと個別接点6b,6cからなる固定接点が配されるようにスイッチケース2にそれぞれ収容されており、操作体4の下方には、押圧部4bと、導電体たる可動接点体5および固定接点が存在しないように収容される。   Thus, the pressing part 4b is arranged on the vertical side of the operating body 4 in the tilt direction, the movable contact body 5 is arranged below the pressing part 4b, and the common contact 6a and the individual contacts 6b, Each of the switch cases 2 is accommodated in a switch case 2 so that a fixed contact made of 6c is arranged, and is placed below the operation body 4 so that the pressing portion 4b, the movable contact body 5 as a conductor and the fixed contact do not exist.

操作体4と、押圧部4b、導電体たる可動接点体5と固定接点の収容位置関係についてさらに詳しく説明する。   The accommodation position relationship among the operation body 4, the pressing portion 4b, the movable contact body 5 as a conductor, and the fixed contact will be described in more detail.

図2(a)(b)に示すように、スイッチケース2は、上面が開口した箱形であり、内底面に仕切り壁2aが立設されている。スイッチケース2には、この仕切り壁2aにより、二つの空間が操作体収容空間2bおよび導電体収容空間2cとして隔離されて形成されている。   As shown in FIGS. 2 (a) and 2 (b), the switch case 2 has a box shape with an open top surface, and a partition wall 2a is erected on the inner bottom surface. The switch case 2 is formed by separating the two spaces as the operating body housing space 2b and the conductor housing space 2c by the partition wall 2a.

スイッチケース2内には、操作体4と、押圧部4bおよび導電体が隔離されて設置されている。操作体収容空間2bには、操作体4が設置され、導電体収容空間2cには、押圧部4bと、導電体たる可動接点体5および固定接点6が設置されて、仕切り壁2aにより隔離されている。   In the switch case 2, the operating body 4, the pressing portion 4 b and the conductor are installed separately. An operating body 4 is installed in the operating body housing space 2b, and a pressing portion 4b, a movable contact body 5 as a conductor, and a fixed contact 6 are installed in the conductor housing space 2c, and are isolated by the partition wall 2a. ing.

また、スイッチケース2には、仕切り壁2aと、スイッチケース2を形成する仕切り壁2aと対向した操作体収容空間2b側の側壁とに、幅および深さがほぼ同じ長さとなるU字形の溝部2dが穿設されている。特に仕切り壁2aに穿設される溝部2dは、仕切り壁2aを貫穿するように穿設されている。   Further, the switch case 2 has a U-shaped groove portion having substantially the same width and depth on the partition wall 2a and the side wall on the side of the operating body accommodation space 2b facing the partition wall 2a forming the switch case 2. 2d is drilled. In particular, the groove 2d formed in the partition wall 2a is formed so as to penetrate the partition wall 2a.

操作体4および押圧部4bは、この溝部2dによって各収納空間に設置されるものである。   The operating body 4 and the pressing part 4b are installed in each storage space by the groove 2d.

操作体4および押圧部4bについてさらに詳しく説明する。図3に示すように、操作体4は、長形板の両長辺上部側を傾斜状に切り欠いた形状を有している。   The operating body 4 and the pressing part 4b will be described in more detail. As shown in FIG. 3, the operating body 4 has a shape in which the upper sides of both long sides of the long plate are cut out in an inclined manner.

操作体4には、両板面下部側に、両板面から突出するように軸部4aが一体に形成されている。この軸部4aは、円柱形状を有し、直径がスイッチケース2に穿設された溝部2dの幅および深さと同じ長さになるように形成され、軸部4aが溝部2dに傾合した際に回転自在であるが空隙が生じない程度の大きさとなっている。   The operating body 4 is integrally formed with a shaft portion 4a on the lower side of both plate surfaces so as to protrude from both plate surfaces. The shaft portion 4a has a cylindrical shape and is formed so that the diameter thereof is the same length as the width and depth of the groove portion 2d drilled in the switch case 2, and when the shaft portion 4a is inclined to the groove portion 2d. However, the size is such that no gap is generated.

軸部4aの一方の端面には、略扇形形状のフランジ部4cが、軸部4aと一体形成されている。このフランジ部4cの軸部4aにおける形成位置は、上方に円弧を配して軸部4a上方に所定部分突出するような位置関係になっている。さらに、このフランジ部4c上には、押圧部が所定の厚みを持って一体に形成されている。この押圧部4bは、フランジ部4cの円弧と弦で囲まれた半月部分と同形状である。そして、フランジ部4cの円弧と弦で囲まれた半月部分に一体に形成されている。 A substantially sector-shaped flange portion 4c is integrally formed with the shaft portion 4a on one end face of the shaft portion 4a. The formation position of the flange portion 4c in the shaft portion 4a is in a positional relationship such that a circular arc is arranged upward and a predetermined portion protrudes above the shaft portion 4a. Further, a pressing portion is integrally formed with a predetermined thickness on the flange portion 4c. The pressing portion 4b has the same shape as the half-moon portion surrounded by the arc and string of the flange portion 4c. And it is integrally formed in the half-moon part enclosed by the circular arc and the string of the flange part 4c.

このように操作体4と押圧部4bは、軸部4aの一端面上にフランジ部4cを介して操作体の一板面側に一体形成されている。したがって、操作体4と押圧部4bは、軸部4aとフランジ部4cを介することによって一体形成される。 Thus, the operating body 4 and the pressing part 4b are integrally formed on the one plate surface side of the operating body on the one end face of the shaft part 4a via the flange part 4c. Therefore, the operating body 4 and the pressing part 4b are integrally formed through the shaft part 4a and the flange part 4c.

この一体形成された操作体4と押圧部4bは、図2に示すように、軸部4aを溝部2dに回転自在に係合させることにより、スイッチケース2内に収容される。このとき、仕切り壁2aに、操作体4と押圧部4bを介する軸部4aの押圧部4b側が係合されることにより、操作体4と押圧部4bは、仕切り壁2aによって隔離され、異なる収容空間に収容されることとなり、操作体4が操作体収容空間2bに収容されるように、押圧部4bが導電体収容空間2cに収容される。   As shown in FIG. 2, the integrally formed operating body 4 and pressing portion 4 b are accommodated in the switch case 2 by engaging the shaft portion 4 a with the groove portion 2 d in a rotatable manner. At this time, the operating body 4 and the pressing portion 4b are separated by the partition wall 2a by the partition wall 2a being engaged with the pressing portion 4b side of the shaft portion 4a via the operating body 4 and the pressing portion 4b. The pressing portion 4b is housed in the conductor housing space 2c so that the operation body 4 is housed in the operation body housing space 2b.

ここで、操作体4は、側縁を傾動方向としてスイッチケース2に収容されることとなる。すなわち、軸部4aは、操作体4の傾動方向鉛直面の両面に形成されるものであり、押圧部4bも軸部4aを介して傾動方向鉛直側に配される。尚、操作体4が、例えば、円柱体で形成されていても、軸部4aは、操作体4の周部であって傾動方向鉛直両側に形成されることとなり、したがって操作体4の傾動方向鉛直面の両面に形成されることとなる。また、押圧部4bも軸部4aを介して傾動方向鉛直側に配されることとなる。   Here, the operating body 4 is accommodated in the switch case 2 with the side edge as the tilting direction. That is, the shaft portion 4a is formed on both surfaces of the operation body 4 in the tilt direction vertical surface, and the pressing portion 4b is also arranged on the tilt direction vertical side via the shaft portion 4a. Note that even if the operating body 4 is formed of, for example, a cylindrical body, the shaft portion 4a is formed on the periphery of the operating body 4 and on both sides in the tilting direction. It will be formed on both sides of the vertical surface. Further, the pressing portion 4b is also arranged on the vertical side of the tilting direction via the shaft portion 4a.

さらに、図2に示すように、この導電体収容空間2cには、押圧部4bの下方に可動接点体5が配される。さらに、導電体収容空間2cの内底面に露出するように共通接点6aと個別接点6b,6cからなる固定接点が配され、外部に導出される際には、操作体収納空間2bの内底面よりも下方を通り外部へ導出される。   Further, as shown in FIG. 2, a movable contact body 5 is disposed in the conductor housing space 2c below the pressing portion 4b. Further, a fixed contact made up of a common contact 6a and individual contacts 6b and 6c is arranged so as to be exposed at the inner bottom surface of the conductor housing space 2c, and when led out to the outside, from the inner bottom surface of the operation body housing space 2b. Is also led out to the outside.

これにより、導電体収容空間2cには、押圧部4bと、可動接点体5および固定接点6といった導電体が収容され、操作体4が収容される操作体収容空間2bと隔離される。   Thereby, conductors such as the pressing portion 4b, the movable contact body 5 and the fixed contact 6 are accommodated in the conductor accommodation space 2c, and are isolated from the operation body accommodation space 2b in which the operation body 4 is accommodated.

さらに、スイッチカバー3の開口部3aは、操作体収容空間2bの上方に位置する箇所にのみ穿設される。導電体収容空間2cの上方に位置する箇所は完全にスイッチカバー3の内底面に被覆され、スイッチケース2とスイッチカバー3がフランジ2eにより嵌合される。これにより、導電体収容空間2cは操作体収容空間2bと隔離され、外気と隔離される。   Furthermore, the opening 3a of the switch cover 3 is drilled only at a location located above the operating body accommodation space 2b. The portion located above the conductor housing space 2c is completely covered with the inner bottom surface of the switch cover 3, and the switch case 2 and the switch cover 3 are fitted by the flange 2e. As a result, the conductor housing space 2c is isolated from the operating body housing space 2b and from the outside air.

このように、レバースイッチ1は、開口部3aが操作体4の傾動動作の範囲を所定範囲許容するために生ずる開口部3aと操作体4の隙間により外気が導通する操作体収容空間2bと、操作体収容空間2bと隔離された導電体収容空間2cを有する。そして、導電体収容空間2cに押圧部4bと、導電体たる可動接点体5と固定接点を収容することにより、導電体が外気に触れることを阻止する構成となっている。   As described above, the lever switch 1 includes the operating body accommodating space 2b in which the outside air is conducted by the gap between the opening 3a and the operating body 4 generated in order that the opening 3a allows a predetermined range of the tilting operation of the operating body 4. It has a conductor housing space 2c isolated from the operating body housing space 2b. And it is the structure which prevents that a conductor touches external air by accommodating the press part 4b, the movable contact body 5 which is a conductor, and a fixed contact in the conductor accommodation space 2c.

次に、このレバースイッチ1の動作を図4に基づき説明し、同時に、この動作に伴う外気の流れを説明する。   Next, the operation of the lever switch 1 will be described with reference to FIG. 4, and simultaneously the flow of outside air accompanying this operation will be described.

まず、レバースイッチ1の静止状態において、操作体4の両側縁と開口部3aとの間には空隙が存在し、レバースイッチ1の外部と操作体収容空間2bとは、開口部3aを通して通気状態にある。   First, when the lever switch 1 is stationary, there is a gap between the side edges of the operating body 4 and the opening 3a, and the outside of the lever switch 1 and the operating body housing space 2b are in a vented state through the opening 3a. It is in.

操作体収容空間2bと導電体収容空間2cは、仕切り壁2aにより隔離されており、水分等は操作体収納空間2bから導電体収容空間2cには入り込まない。 The operation body housing space 2b and the conductor housing space 2c are separated by the partition wall 2a , and moisture or the like does not enter the conductor housing space 2c from the operation body housing space 2b.

以下において、操作体4がいかに傾動し、開口部3aを介して外気と操作体収容空間2bが通気状態にあろうとも、導電体収容空間2cに水分が入り込むことはない。 In the following, no matter how the operating body 4 tilts and the outside air and the operating body accommodating space 2b are in a vented state through the opening 3a , moisture does not enter the conductor accommodating space 2c.

さらに、フランジ部4cにより、溝部2dのU字型形状と軸部4aの円柱形状から生ずる空隙をも塞がれている。このフランジ部4cにより導電体収容空間2cに水分が入り込むことを予備的に防がれている。 Further, the flange portion 4c closes a gap generated from the U-shaped shape of the groove portion 2d and the cylindrical shape of the shaft portion 4a . The flange portion 4c preliminarily prevents moisture from entering the conductor housing space 2c .

このとき、押圧部4bは、操作体4が傾動動作されていないから、可動接点体底辺5aに当接するのみであり、可動接点5b,5cは共通接点6a上に維持され、固定接点6b,6cとは非接触状態にある。   At this time, since the operating body 4 is not tilted, the pressing portion 4b only comes into contact with the movable contact body bottom 5a, and the movable contacts 5b and 5c are maintained on the common contact 6a and the fixed contacts 6b and 6c. Is in a non-contact state.

図4(a)に示すように、操作体4が個別接点6bに摺動開始されると、操作体4の傾動方向鉛直側に位置する押圧部4bは、操作体4が図2(b)等に示す軸部4a(以下、図2(b)を参照)を中心に回転し始めることにより共動し、操作体4の傾動角度と同角度に傾動される。   As shown in FIG. 4 (a), when the operating body 4 starts to slide on the individual contact 6b, the operating body 4 in the pressing portion 4b located on the vertical side in the tilting direction of the operating body 4 is shown in FIG. As a result of the rotation starting around a shaft portion 4a (see FIG. 2B) shown in FIG.

この傾動動作により、押圧部4bは、操作体4の傾動運動を媒介し、可動接点体底辺5aを傾動方向に押圧する。この押圧によって可動接点体5の傾動方向とは反対側の折り曲げ部分がスイッチケース2およびスイッチカバー3に当接して、この当接した部分を支点として可動接点体底辺5aが下向きに撓み、この撓みにより、傾動方向側の折り曲げ部分から撓み始めて、可動接点5cが傾動方向反対側に摺動し始める。   By this tilting operation, the pressing portion 4b mediates the tilting motion of the operating body 4 and presses the movable contact body bottom 5a in the tilting direction. By this pressing, the bent portion of the movable contact body 5 opposite to the tilting direction comes into contact with the switch case 2 and the switch cover 3, and the movable contact body bottom 5a is bent downward with the contacted portion as a fulcrum. As a result, the movable contact 5c begins to bend from the bent portion on the tilt direction side, and the movable contact 5c starts to slide to the opposite side in the tilt direction.

可動接点5bが先端に位置している一辺は可動接点体5の支点となっている位置から折り曲げられているので撓み変形はせず、可動接点5bは、共通接点6a上を維持して接触状態を維持している。   One side where the movable contact 5b is located at the tip is bent from the position which is a fulcrum of the movable contact body 5, so that it does not bend and deform, and the movable contact 5b maintains a contact state on the common contact 6a. Is maintained.

操作体4の傾動動作によってフランジ部4cも軸部4aを中心に回転し始めるが、フランジ部4cの扇形形状により、なお軸部4aと溝部2dに生ずる空隙が塞がれ、導電体収容空間2cは密閉状態が維持されている。 Although the flange portion 4c also starts to rotate around the shaft portion 4a by the tilting operation of the operation body 4, the gap formed in the shaft portion 4a and the groove portion 2d is blocked by the sector shape of the flange portion 4c, and the conductor housing space 2c. The sealed state is maintained.

図4(b)に示すように、さらに操作体4が摺動動作され、操作体4が開口部3aにおけるスイッチカバー3の側壁の掘り込み部分まで達し、傾動許容範囲まで達すると、押圧部4bは、操作体4の傾動運動を媒介し、可動接点体底辺5aを傾動方向にさらに押圧する。この押圧によって可動接点体底辺5aがさらに下向きに撓み、この撓みにより、傾動方向側の折り曲げ部分からさらに撓み、可動接点5cがさらに摺動し、傾動方向反対側の個別接点6cに達して、可動接点5cと個別接点6cが接触する。   As shown in FIG. 4 (b), the operating body 4 is further slid, and when the operating body 4 reaches the digging portion of the side wall of the switch cover 3 in the opening 3a and reaches the tilt allowable range, the pressing portion 4b. Mediates the tilting motion of the operating body 4 and further presses the movable contact body bottom 5a in the tilting direction. By this pressing, the bottom 5a of the movable contact body is further bent downward, and this bending further causes bending from the bent portion on the tilt direction side, and the movable contact 5c slides further, reaches the individual contact 6c on the opposite side in the tilt direction, and is movable. The contact 5c contacts the individual contact 6c.

これにより、共通接点6aと個別接点6cが、可動接点5bと可動接点5cとそれぞれ接触することにより可動接点体5を介して電気回路を形成して導通する。   As a result, the common contact 6a and the individual contact 6c are brought into conduction by forming an electric circuit via the movable contact body 5 by making contact with the movable contact 5b and the movable contact 5c, respectively.

操作体4の傾動動作によってフランジ部4cも軸部4aを中心に回転許容範囲まで回転するが、フランジ部4cの扇形形状により、なおも軸部4aと溝部2dに生ずる空隙が塞がれ、導電体収容空間2cは密閉状態が維持されている。すなわち、フランジ部4cは、操作体4が傾動動作されても常に軸部4aと溝部2dに生ずる空隙が塞いでいる。 The flange portion 4c also rotates to the rotation allowable range around the shaft portion 4a by the tilting operation of the operating body 4, but the gap formed in the shaft portion 4a and the groove portion 2d is blocked by the fan-shaped shape of the flange portion 4c. The body housing space 2c is kept sealed. That is, the flange portion 4c always closes the gap generated in the shaft portion 4a and the groove portion 2d even when the operating body 4 is tilted.

操作体の傾動方向を個別接点6c側にした場合には、共通接点6aと可動接点5cが接触し、個別接点6bと可動接点5bが接触し、可動接点5を介して、個別接点6b側に形動させて導通させた電気回路と異なる電気回路を形成して導通する。   When the tilting direction of the operating body is set to the individual contact 6c side, the common contact 6a and the movable contact 5c come into contact with each other, the individual contact 6b and the movable contact 5b come into contact with each other, and the movable contact 5 is brought into the individual contact 6b side. An electric circuit that is different from the electric circuit that has been moved and formed is formed to be conductive.

この傾動動作においても、常に、操作体収納空間2bと導電体収納空間2cは断絶されて導電体収納空間2cに水分が入り込むのを防ぎ、かつ常にフランジ部4cにより軸部4aと溝部2dに生ずる空隙が塞がれる。 Even in this tilting operation, the operating body storage space 2b and the conductor storage space 2c are always cut off to prevent moisture from entering the conductor storage space 2c, and always generated in the shaft portion 4a and the groove portion 2d by the flange portion 4c. The gap is blocked.

このように、レバースイッチ1は、金属で形成された導電体たる可動接点体5や固定接点を導電体収納空間2cに収納し、導電体収納空間を操作体4が収納される操作体収納空間2bと仕切り壁2aによって隔離するようにしたことにより、導電体側への水分の入り込みを効果的に防止でき、水分によりショートすることもなく、耐久性に優れる。さらに、フランジ部4cによって溝部2dがどのような形状に穿設されようとも軸部4a周りに生ずるおそれのある空隙を塞ぐことができ、かかる空隙から導電体収納空間2cへの水分の入り込みを効果的に防止することができる。 As described above, the lever switch 1 stores the movable contact body 5 and the fixed contact, which are conductors made of metal, in the conductor storage space 2c, and the operation body storage space in which the operation body 4 is stored. by you to isolate by 2b and the partition wall 2a, entry of moisture into the conductor side can be effectively prevented, without even a short circuit due to moisture, excellent in durability. Further, no matter what shape the groove portion 2d is drilled by the flange portion 4c, it is possible to close a gap that may be generated around the shaft portion 4a , and it is effective for moisture to enter the conductor housing space 2c from the gap. Can be prevented .
