Description
【0001】[0001]
この考案は、自動車のパワーウインド等の開閉に用いられるラバーキースイッ チの改良に関する。 The present invention relates to an improvement of a rubber key switch used for opening and closing a power window of an automobile.
【0002】[0002]
従来、ラバーキースイッチは、例えば図3、図4に示す構造のものがある。図 3に示す従来技術は、実開平3−12326号公報に開示しているラバーキース イッチであるがラバーキースイッチ本体1を筺体(図示せず)とプリント基板2 との間に挟み込んで実装し、上記ラバーキースイッチ本体の周縁部下面シール部 3がプリント基板2に密着して外部からの塵や水分の侵入を防止している。 Conventionally, there is a rubber key switch having a structure shown in FIGS. 3 and 4, for example. The prior art shown in FIG. 3 is a rubber key switch disclosed in Japanese Utility Model Laid-Open No. 3-12326, but the rubber key switch body 1 is mounted by being sandwiched between a housing (not shown) and a printed circuit board 2. The peripheral lower surface seal portion 3 of the rubber key switch body is in close contact with the printed circuit board 2 to prevent dust and water from entering from the outside.
【0003】 上記ラバーキースイッチ本体1は押しボタン部4,4を押圧して円錐状に成形 したスイッチ部5,5の内側に設けた可動接点6とプリント基板2に印刷した固 定接点7が接触してONする。又この時円錐状に成形したスイッチ部5,5が屈 曲し空洞部8,8から押し出された空気は通気路9を通り空気室10へ逃げ内圧 の上昇を抑えてスイッチ操作時の抵抗を解消している。The rubber key switch body 1 has a movable contact 6 provided inside the conical switch parts 5 and 5 which press the push button parts 4 and 4, and a fixed contact 7 printed on the printed circuit board 2. Contact and turn on. At this time, the conical shaped switch parts 5 and 5 bend and the air pushed out from the hollow parts 8 and 8 escapes to the air chamber 10 through the ventilation passage 9 and suppresses the rise of the internal pressure to reduce the resistance when the switch is operated. It has disappeared.
【0004】 また他の例としての図4に示す従来技術は、ラバーキースイッチ本体11に図 3に示す上記空気室10の位置にランプ室12を設け、シール部3の部分に通気 路13,13を備えたものであり此の二点を除き他の構成は図3の構造と同一で ある。該ラバーキースイッチ本体11はランプ室12に設けたランプ14によっ て上方を照光し、スイッチがONするとスイッチ部15,15が屈曲し内側空洞 部16,16の空気は通気路13,13を通り大気中に排出されスイッチ操作時 に於ける操作性を円滑化する。As another example of the conventional technique shown in FIG. 4, a rubber key switch body 11 is provided with a lamp chamber 12 at the position of the air chamber 10 shown in FIG. 13 is the same as the structure of FIG. 3 except for these two points. The rubber key switch body 11 is illuminated upward by a lamp 14 provided in a lamp chamber 12, and when the switch is turned on, the switch portions 15 and 15 are bent and the air in the inner cavity portions 16 and 16 flows through the ventilation passages 13 and 13. It is discharged into the atmosphere as it passes through and facilitates the operability when operating the switch.
【0005】[0005]
上記従来技術に於いて、図3に示す従来技術は、スイッチをONしたときスイ ッチ部5,5が屈曲し内側空洞部8,8の空気は通気路9を通り空気室10で内 圧の上昇を抑えシール部3で外部からの塵や水分の侵入を防止している。しかし ランプを収容するランプ室がないため照光用スイッチとしては使用できない問題 がある。又、図4に示す従来技術はランプ室12に設けたランプ14によって上 方を照光する照光用スイッチであるがスイッチ部15,15の空洞部16,16 から押し出される空気を通気路13,13で外部へ逃がす構造のため外部からの 塵や水分が通気路13,13から侵入し故障が発生しやすいという問題がある。 In the prior art shown in FIG. 3, in the prior art shown in FIG. 3, when the switch is turned on, the switches 5 and 5 are bent and the air in the inner cavities 8 and 8 passes through the ventilation passage 9 to generate internal pressure in the air chamber 10. Is prevented from rising, and the seal portion 3 prevents dust and water from entering from the outside. However, there is a problem that it cannot be used as an illumination switch because there is no lamp room to accommodate the lamp. Further, the prior art shown in FIG. 4 is an illumination switch for illuminating the upper side by the lamp 14 provided in the lamp chamber 12, but the air pushed out from the cavity portions 16 and 16 of the switch portions 15 and 15 is ventilated through the ventilation passages 13 and 13. Since it is a structure that escapes to the outside, there is a problem that dust and water from the outside enter from the ventilation passages 13 and 13 and easily cause a failure.
【0006】[0006]
この考案は、上記欠点に鑑みラバーキースイッチ本体が、ケースに圧接される 周縁部下面にプリント基板に密着し外部からの塵や水分の侵入を防止するシール 部を形成し、該ラバーキースイッチ本体の各押しボタン部の押圧時にスイッチ部 の空洞部から押し出される空気を逃がす通気路と、該通気路につながり上記空洞 部から押し出される空気による内圧の上昇を抑えると共にランプを収容して上方 を照光するランプ空気室とを、一体に形成したことを特徴とするものである。 In view of the above drawbacks, the present invention has a rubber key switch body, in which a seal portion is formed on the lower surface of a peripheral portion which is pressed against a case so as to be in close contact with a printed circuit board and prevent intrusion of dust and water from the outside. The ventilation passage that allows the air pushed out of the cavity of the switch to escape when each push button is pressed, and the rise in the internal pressure due to the air that is connected to the ventilation passage and pushed out of the cavity is suppressed and the lamp is housed to illuminate the upper side. It is characterized in that it is integrally formed with the lamp air chamber.

【0009】 上記ラバーキースイッチ本体20は、周縁部をケース29の押圧部30とプリ ント基板31との間に挟み込んで実装し、周縁部下面のシール部21がプリント 基板31に密着して外部からの塵や水分の侵入を防止している。即ち、押圧部3 0がその押圧力によってシール部21を完全にプリント基板31に圧接できるも のである。The rubber key switch body 20 is mounted by inserting the peripheral edge portion between the pressing portion 30 of the case 29 and the printed board 31, and the seal portion 21 on the lower surface of the peripheral edge is brought into close contact with the printed circuit board 31 and externally. Prevents dust and water from entering. That is, the pressing portion 30 can completely press the seal portion 21 against the printed circuit board 31 by the pressing force.
【0010】 ランプ空気室27は、ランプ室と空気室の二つの機能を備えたものであり第一 の機能は球面部24の表面を透光性の着色をして照光の色を変えると共に球面部 24でプリント基板31に設けたランプ32の光を拡散して上方ケース29の透 光部33を照光する為のランプ32を収容するランプ室である。 又第二の機能としては、ケース29の開口部34,34に出没自在に挿設して 上記ラバーキースイッチ本体20の押しボタン部22,22を付勢しているノブ 35,35の押圧操作により円錐状に成形したスイッチ部23,23が屈曲して 内側の空洞部26,26から押し出された空気による内圧の上昇を抑えてスイッ チ操作時の抵抗を解消する空気室である。The lamp air chamber 27 has two functions of a lamp chamber and an air chamber. The first function is to change the color of the illumination by changing the color of the illumination by coloring the surface of the spherical portion 24 with a light-transmitting color. The lamp chamber accommodates the lamp 32 for diffusing the light of the lamp 32 provided on the printed circuit board 31 in the section 24 and illuminating the translucent section 33 of the upper case 29. The second function is to push the knobs 35, 35 that are inserted into and retracted from the openings 34, 34 of the case 29 to urge the push button portions 22, 22 of the rubber key switch body 20. This is an air chamber that bends the conical switch parts 23, 23 and suppresses an increase in internal pressure due to the air pushed out from the inner cavity parts 26, 26, thereby eliminating the resistance during the switch operation.
【0011】 通気路28,28は、上記スイッチ部23,23の空洞部26,26とランプ 空気室27との間に形成して成り、ケース29の開口部34,34に出没自在に 挿設して上記ラバーキースイッチ本体20の押しボタン部22,22を付勢して いるノブ35,35の押圧操作により可動接点25と固定接点36が接触してス イッチがONするとスイッチ部23,23の空洞部26,26から押し出された 空気を内圧の上昇を抑えるランプ空気室へと逃がす通気路である。The ventilation passages 28, 28 are formed between the hollow portions 26, 26 of the switch portions 23, 23 and the lamp air chamber 27, and are inserted into and retractable from the openings 34, 34 of the case 29. Then, when the movable contact 25 and the fixed contact 36 come into contact with each other by the pressing operation of the knobs 35, 35 for urging the push button portions 22, 22 of the rubber key switch body 20 and the switch is turned on, the switch portions 23, 23 This is a ventilation path for allowing the air pushed out from the hollow portions 26, 26 of the lamp to escape to the lamp air chamber that suppresses the rise in internal pressure.
【0012】[0012]
この考案は、ラバーキースイッチ本体の周縁部下面にシール部を形成し、押し ボタン部の押圧時に各スイッチ部の空洞部から押し出される空気を逃がす通気路 と、該通気路につながり上記空洞部から押し出された空気による内圧の上昇を抑 えると共にランプを収容して上方を照光するランプ空気室とを、上記ラバーキー スイッチ本体に一体に形成したことによりケースの押圧部で押圧するのでシール 部がプリント基板に密着し外部からの塵や水分の侵入を防止すると共にランプに よって上方を照光できるという二つの機能を一つのラバーキースイッチに備える ことにより部品数と価格を低減できる。 According to the invention, a seal portion is formed on the lower surface of the peripheral portion of the rubber key switch body, and a ventilation passage for releasing air pushed out from the cavity of each switch portion when the push button portion is pressed, and a ventilation passage connected to the ventilation passage Since the rise of the internal pressure due to the extruded air is suppressed and the lamp air chamber that houses the lamp and illuminates the upper part is integrally formed with the rubber key switch body by the pressing part of the case, the seal part is printed. It is possible to reduce the number of parts and the cost by providing one rubber key switch with the two functions of being in close contact with the substrate and preventing the ingress of dust and water from the outside, and being able to illuminate the upper side with a lamp.
