Description

本発明は、主に自動車のルームランプやハザードランプ等の消点灯操作に用いる押釦スイッチに関するものである。   The present invention relates to a pushbutton switch mainly used for a turn-off operation such as a room lamp or a hazard lamp of an automobile.

近年、自動車のルームランプやハザードランプ等の消点灯操作用として、他のインストルメントパネル等の操作スイッチとは異なり、ON/OFF時の操作位置が判り易いように操作ストロークの長い、所謂、長ストロークの押釦スイッチを用いることが増えてきている。   In recent years, for operation of turning off and turning on automobile room lamps, hazard lamps, etc., unlike other operation switches such as instrument panels, the operation position has a long operation stroke so that the operation position at ON / OFF can be easily understood. The use of stroke pushbutton switches is increasing.

このような従来の押釦スイッチについて、図7及び図8を用いて説明する。   Such a conventional push button switch will be described with reference to FIGS.

図7は従来の押釦スイッチの部分断面図であり、同図において、1は上面開口の略箱状で絶縁樹脂製のケースで、ケース1内には複数の固定接点2が植設され、その端子部がケース1側面から外方に延出している。   FIG. 7 is a partial cross-sectional view of a conventional pushbutton switch. In FIG. 7, reference numeral 1 denotes a substantially box-like case with an opening on the upper surface, and a plurality of fixed contacts 2 are implanted in the case 1. The terminal portion extends outward from the side surface of the case 1.

そして、3は絶縁樹脂製の操作体で、ケース1内に上下動可能に収納されると共に、この操作体3の上下動に伴って、操作体3に固定された可動接片(図示せず)が、ケース1内の固定接点2と電気的接離を行うようにしてスイッチ接点が構成されている。   An operating body 3 made of an insulating resin is housed in the case 1 so as to be movable up and down. A movable contact piece (not shown) fixed to the operating body 3 as the operating body 3 moves up and down. However, the switch contact is configured so as to be electrically connected to and separated from the fixed contact 2 in the case 1.

また、4はケース1上面の開口部を覆うカバーで、このカバー4上面略中央の通孔(図示せず)から、操作体3の操作部3Aが上方ヘ突出すると共に、操作部3A上端には先端部3Bとこれより幅の小さな係合溝3Cが設けられている。   Reference numeral 4 denotes a cover that covers the opening on the upper surface of the case 1, and the operation portion 3 </ b> A of the operation body 3 protrudes upward from a through hole (not shown) in the substantially center of the upper surface of the cover 4. Is provided with a front end 3B and a smaller engaging groove 3C.

さらに、5は絶縁樹脂製の押釦で、下面略中央にはコの字状に対向した長さ寸法Aの取付部5Aが下方へ突出して形成され、この取付部5Aが操作体3の先端部3Bや係合溝3C外周を覆うと共に、取付部5A内周の突起部5Bが係合溝3Cに係合して、押釦5が操作体3に装着されている。   Further, reference numeral 5 denotes a push button made of insulating resin, and a mounting portion 5A having a length dimension A facing the U-shape is formed in a substantially central portion on the lower surface so as to protrude downward. 3B and the outer periphery of the engagement groove 3C are covered, and the protrusion 5B on the inner periphery of the attachment portion 5A is engaged with the engagement groove 3C so that the push button 5 is attached to the operating body 3.

なお、取付部5A下端とカバー4上面との間には、操作体3が上下動するストロークLに相当する寸法分の間隙が空けられている。   Note that a gap corresponding to a stroke L corresponding to the vertical movement of the operating body 3 is provided between the lower end of the mounting portion 5A and the upper surface of the cover 4.

従って、カバー4上面から押釦5上面までの寸法は、このストロークL分の間隙に、押釦5下面の取付部5Aの長さ寸法A、及び押釦5の厚さを加えた高さとなっている。   Therefore, the dimension from the upper surface of the cover 4 to the upper surface of the push button 5 is a height obtained by adding the length dimension A of the mounting portion 5A on the lower surface of the push button 5 and the thickness of the push button 5 to the gap corresponding to the stroke L.

そして、ケース1内には操作体3を上方に付勢するコイルばね(図示せず)が収納されると共に、操作体3のカム部(図示せず)やストッパ(図示せず)によってロック機構が形成されて、押釦スイッチが構成されている。   A coil spring (not shown) that biases the operating body 3 upward is housed in the case 1, and a locking mechanism is provided by a cam portion (not shown) or a stopper (not shown) of the operating body 3. Is formed to constitute a push button switch.

また、このような押釦スイッチは、例えば、車室内の天井に取付けられたルームライト装置内の配線基板等に実装され、押釦5が装置の操作パネル(図示せず)の開口部から突出して配置される。   Such a push button switch is mounted on, for example, a wiring board in a room light device attached to the ceiling of the vehicle interior, and the push button 5 is disposed so as to protrude from an opening of an operation panel (not shown) of the device. Is done.

以上の構成において、押釦5を下方へ押圧操作すると、ケース1内のコイルばねを撓めながら操作体3が下方へ移動し、図8の部分断面図に示すように、ストロークLだけ降下すると、押釦5の取付部5A下端がカバー4上面に当接して、ケース1内のスイッチ接点の電気的接離が行われ、例えばスイッチ接点がONとなって、ルームライトが点灯する。   In the above configuration, when the push button 5 is pressed downward, the operating body 3 moves downward while bending the coil spring in the case 1, and as shown in the partial sectional view of FIG. The lower end of the mounting portion 5A of the push button 5 comes into contact with the upper surface of the cover 4, and the switch contact in the case 1 is electrically connected / separated. For example, the switch contact is turned on and the room light is turned on.

また、この状態から押釦5への押圧力を解除すると、コイルばねによって付勢された操作体3がやや上方へ移動すると共に、ケース1内のストッパが操作体3のカム部の所定箇所に係止して、操作体3がロックされた状態となる。   Further, when the pressing force to the push button 5 is released from this state, the operating body 3 biased by the coil spring moves slightly upward, and the stopper in the case 1 is engaged with a predetermined portion of the cam portion of the operating body 3. The operation body 3 is locked and stopped.

さらに、この後、再び押釦5を押圧操作すると、ストッパとカム部との係止が外れてロック状態が解除され、操作体3が上方ヘ移動して、図7の状態に戻ると共に、スイッチ接点がOFFとなりルームライトが消灯するように構成されているものであった。   Further, after that, when the push button 5 is pressed again, the stopper and the cam portion are disengaged, the locked state is released, the operating body 3 moves upward, returns to the state of FIG. Is configured to be off and the room light is turned off.
