The operation body swings around the support shaft by the seesaw operation and is driven by the compression coil spring. The body is moved while pressing a seesaw-type conductor plate (movable contact piece) provided with a movable contact at one end, so that the seesaw-type conductor plate swings with the center terminal supporting the center part as a fulcrum. It moves (seesaw motion), and the fixed contact and the movable contact arranged at the position facing the movable contact come in and out of contact. When the movable contact comes into contact with the fixed contact, the fixed terminal provided with the fixed contact conducts through the center terminal and the seesaw-shaped conductor plate, and connects the external circuit connected to the center terminal and the external circuit connected to the fixed terminal. To do.

上記シーソー式スイッチ装置は、その用途によっては高い防水防塵性能が求められている。本考案は、その防水防塵性能を満足させるための構造に関する。  The seesaw type switch device is required to have high waterproof and dustproof performance depending on its application. The present invention relates to a structure for satisfying the waterproof and dustproof performance.

当該考案の出願に関わるシーソー式スイッチ装置の先行例を説明する。
図5、図6において、ボディ回転軸4aにノブ回転軸孔1aが嵌合し、ノブ1がその軸を中心に揺動可能に支持される。ノブ円筒部1c内部に圧縮コイルばね3を収納し、その先端に砲弾形状のピース13を設け、ノブ1のシーソー操作によりボディ回転軸4aを中心に揺動し、圧縮コイルばね3により付勢されたピース13を、両端に可動接点を設けたシーソー形の導体板6を押圧しながら移動させることにより、シーソー形の導体板6が、その中央部を支持している中央端子8を支点として揺動(シーソー運動)し、可動接点6a、6bと対向位置に配置した固定接点7a、7bが接離する。可動接点6aまたは6bが固定接点7aまたは7bに当接したとき、固定接点を設けた固定端子が中央端子8とシーソー形の導体板6を通じて導通し、中央端子に接続した外部の電路と固定端子に接続した外部の電路を接続する。
A prior example of a seesaw type switching device related to the application of the device will be described.
5 and 6, the knob rotation shaft hole 1a is fitted to the body rotation shaft 4a, and the knob 1 is supported so as to be swingable about the shaft. The compression coil spring 3 is housed inside the knob cylindrical portion 1 c, and a bullet-shaped piece 13 is provided at the tip thereof. The knob 1 swings around the body rotation shaft 4 a by the seesaw operation, and is biased by the compression coil spring 3. The piece 13 is moved while pressing the seesaw-type conductor plate 6 provided with movable contacts at both ends, so that the seesaw-type conductor plate 6 is swung with the center terminal 8 supporting the center portion as a fulcrum. It moves (seesaw motion), and the movable contacts 6a and 6b are brought into contact with and separated from the fixed contacts 7a and 7b arranged at the opposed positions. When the movable contact 6a or 6b comes into contact with the fixed contact 7a or 7b, the fixed terminal provided with the fixed contact conducts through the central terminal 8 and the seesaw-shaped conductor plate 6, and the external electric circuit connected to the central terminal and the fixed terminal Connect the external electric circuit connected to.

インシュレータ9とボデイ4との突当て面の全周に、ゴムシール11を圧縮状態で配置しているので、インシュレータ9とボデイ4との嵌合面から接点室15内に水滴或いは塵埃が侵入するのを阻止している。  Since the rubber seal 11 is disposed in a compressed state on the entire circumference of the abutting surface between the insulator 9 and the body 4, water droplets or dust enters the contact chamber 15 from the fitting surface between the insulator 9 and the body 4. Is blocking.

ボデイ揺動開口部4bには、ノブ円筒部1cを揺動可能とするための隙間16が設けてある。この隙間16から水滴或いは塵埃が侵入するのを阻止するために、ボディ側パッキング14bの内周とボデイ揺動開口部4bの外周、ノブ側パッキング14aの内周とノブ円筒部1bの外周とを密着させている。  The body swinging opening 4b is provided with a gap 16 for enabling the knob cylindrical portion 1c to swing. In order to prevent water droplets or dust from entering through the gap 16, the inner circumference of the body side packing 14b, the outer circumference of the body swinging opening 4b, the inner circumference of the knob side packing 14a, and the outer circumference of the knob cylindrical portion 1b are separated. It is in close contact.

ボディ側パッキング14bはボデイ揺動開口部4bに固定されるが、ノブ側パッキング14aはノブ円筒部1cの揺動と共に揺動するので、防水防塵パッキング14は柔軟に屈曲できる形状となっている。  The body side packing 14b is fixed to the body swinging opening 4b. However, since the knob side packing 14a swings with the swing of the knob cylindrical portion 1c, the waterproof and dustproof packing 14 has a shape that can be flexibly bent.

前記ゴムシール11と防水防塵パッキング14によって、ボディ4の内部は、外部と遮断されているので接点室15内に水滴或いは塵埃が侵入するのを阻止している。  The rubber seal 11 and the waterproof and dustproof packing 14 block the inside of the body 4 from the outside, thereby preventing water droplets or dust from entering the contact chamber 15.

特許文献1には、(16図参照)接点室内への水塵等の浸入を防ぐためにスイッチ釦裏面の突出物と仕切り板とを全面的に覆う防水防塵パッキングを柔軟な材料から形成されたダイヤフラム状態で設けることが提案されている。  Patent Document 1 (see FIG. 16) shows a diaphragm in which a waterproof and dustproof packing that covers the protrusions on the back side of the switch button and the partition plate is formed of a flexible material in order to prevent entry of water dust and the like into the contact chamber. Proposed in a state.

特許文献2には、(段落番号0016、および図5参照) スイッチ釦裏面の突出部の周囲に、仕切り板の開口部との間の隙間を閉鎖すべく防塵板が仕切り板上に摺動自在に配置され、かつ仕切り板に対してばね付勢して、防塵性能を高めることが提案されている。  In Patent Document 2 (see paragraph number 0016 and FIG. 5), a dustproof plate is slidable on the partition plate so as to close a gap between the switch button back surface and the opening of the partition plate. It has been proposed to improve the dustproof performance by urging the partition plate with a spring.

図5、図6に示す従来構造および特許文献1で提案されている構造では、ノブ(スイッチ釦)の動きと共に屈曲する防水防塵パッキングに損傷が生じることなく長期間に亘って使用に供するためには、該防水防塵パッキングに或る程度の大きさを与えることが必要である。さもなければ、その材料疲労のためにひび割れや破損等が早期に生じることになる、また防水防塵パッキングの屈曲がノブの操作フィーリングを悪くすることが考えられる。さらに該防水防塵パッキングは組付け性が悪く組付けるのに時間を要するので、価格的にも高い装置になる。  In the conventional structure shown in FIGS. 5 and 6 and the structure proposed in Patent Document 1, the waterproof and dustproof packing that bends with the movement of the knob (switch button) is used for a long period of time without causing damage. Needs to give the waterproof and dustproof packing a certain size. Otherwise, cracks and breakage may occur at an early stage due to the material fatigue, and bending of the waterproof and dustproof packing may deteriorate the operation feeling of the knob. Further, the waterproof and dustproof packing is poor in assemblability and requires time to assemble, so that the apparatus is expensive.

特許文献2で提案されている構造は、前述の防水防塵パッキングに比べ小型化できる事が提案されている。しかし、仕切り板とその上を摺動する防塵板との間の防水性能は防水防塵パッキングに比べ劣る欠点があった。  It has been proposed that the structure proposed in Patent Document 2 can be reduced in size compared to the waterproof and dustproof packing described above. However, the waterproof performance between the partition plate and the dust-proof plate sliding on the partition plate has a disadvantage that it is inferior to the waterproof dust-proof packing.

本考案によれば、前述の防水防塵パッキングに比べ小型化が可能で、かつ組付け性の良い防水防塵構造のシーソー式スイッチ装置を提供できる。  According to the present invention, it is possible to provide a seesaw type switch device having a waterproof and dustproof structure that can be reduced in size as compared with the above-mentioned waterproof and dustproof packing and has good assemblability.

互いに離間して配置された中央端子及び2個の固定接点と、長手方向の略中間部が前記中央端子により支持されており、該中央端子を支点として揺動すると共に、前記中央端子の長手方向の両側部に前記固定接点と接離する可動接点を設けた導体板と、前記導体板の長手方向に沿って揺動可能に支持されたホルダと、前記ホルダの内部に収納された圧縮コイルばねと、前記ホルダの一端には操作ノブの突起が入り込み、他端には前記圧縮コイルばねにより付勢されて、前記ホルダの揺動に伴い、前記導体板を押圧しながら移動する駆動体を備えたシーソー式スイッチ装置において、前記ホルダの外周部にゴムブーツを貫通させ、ゴムブーツの一方をノブの裏面に圧接させ、他端の半球状面をボディ開口部の球状受面に圧接摺動させることを特徴とするものである。  A central terminal and two fixed contacts, which are spaced apart from each other, and a substantially intermediate portion in the longitudinal direction are supported by the central terminal, swing around the central terminal as a fulcrum, and the longitudinal direction of the central terminal A conductive plate provided with movable contacts that come into contact with and away from the fixed contact on both sides thereof, a holder supported so as to be swingable along a longitudinal direction of the conductive plate, and a compression coil spring housed in the holder A protrusion of an operation knob is inserted into one end of the holder, and the other end is urged by the compression coil spring to move while pressing the conductor plate as the holder swings. In the seesaw type switching device, a rubber boot is passed through the outer periphery of the holder, one of the rubber boots is pressed against the back of the knob, and the hemispherical surface at the other end is slid against the spherical receiving surface of the body opening. Special It is an.

本考案によれば、組立性が良く、小型化可能で、好適な操作フィーリングの防水防塵構造のシーソー式スイッチ装置を提供できる。  ADVANTAGE OF THE INVENTION According to this invention, the seesaw type switch apparatus of the waterproof dustproof structure of favorable operation feeling which is easy to assemble and can be reduced in size can be provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a longitudinal side view of a seesaw type switching device according to an embodiment of the present invention, and FIG. 2 is a transverse side view of FIG.

インシュレータ9は、図示してないがボデイ4の嵌合孔にスナップフィットにより固定される。インシュレータ9とボデイ4との突当て面の全周に、ゴムシール11を圧縮状態で配置している。インシュレータ9には固定接点7a、7bと中央端子8が固定されている。導電板6には可動接点6a、6bが固着されている。この導体板6が中央端子8上に嵌合され、揺動可能に支持される。ノブ1は、ノブ嵌合軸穴1aがボディ回転軸4aに揺動可能に嵌合される。ホルダ2の外周に弾性体であるゴムブーツ10が嵌合し、ゴムブーツ10の一方をノブ1の裏面に圧接させ、他端をボディ球状受面4cに圧接させる。ホルダ2の内部には鋼球5、圧縮コイルばね3が収納され、ノブばね押さえ1bがホルダ2内に嵌合して圧縮コイルばね3の一端を押え込む。  Although not shown, the insulator 9 is fixed to the fitting hole of the body 4 by snap fitting. A rubber seal 11 is disposed in a compressed state on the entire circumference of the abutting surface between the insulator 9 and the body 4. Fixed contacts 7 a and 7 b and a center terminal 8 are fixed to the insulator 9. Movable contacts 6 a and 6 b are fixed to the conductive plate 6. The conductor plate 6 is fitted on the center terminal 8 and supported so as to be swingable. The knob 1 is fitted so that the knob fitting shaft hole 1a can swing on the body rotation shaft 4a. A rubber boot 10, which is an elastic body, is fitted to the outer periphery of the holder 2, and one end of the rubber boot 10 is pressed against the back surface of the knob 1 and the other end is pressed against the body spherical receiving surface 4 c. A steel ball 5 and a compression coil spring 3 are housed inside the holder 2, and a knob spring press 1 b is fitted into the holder 2 to press one end of the compression coil spring 3.

図1では、圧縮コイルばね3に押圧された鋼球5が導体板6を押圧しているので、中央端子8と固定接点7aが、シーソー形の導体板6と可動接点6aを通じて導通している。  In FIG. 1, since the steel ball 5 pressed against the compression coil spring 3 presses the conductor plate 6, the central terminal 8 and the fixed contact 7a are electrically connected through the seesaw-shaped conductor plate 6 and the movable contact 6a. .
