Description

本発明は、車両、家庭電化製品等に搭載されるプッシュ式スイッチ装置に関し、特に車両用プッシュ式照光型スイッチ装置に関する。   The present invention relates to a push-type switch device mounted on a vehicle, a home appliance, and the like, and particularly relates to a push-type illuminated switch device for a vehicle.

車両用の電気機器、家庭電化製品を始めとして、多くの電気機器に押圧式スイッチ(プッシュ式スイッチ装置)が搭載されている。例えば、自動車のエアコンディション表示パネル部に搭載され、LED等の発光部(光源)を内部に含む照光型の押圧式スイッチでは、基板に固定された電気スイッチとLEDとを全周にわたり囲む透光性のスイッチノブ(スイッチング部材)が、電気スイッチを押圧して空気調和装置及びLEDを電気的に断続する。   Many electric devices, such as electric devices for vehicles and home appliances, are equipped with a push-type switch (push-type switch device). For example, in an illumination-type push switch that is mounted on an air conditioning display panel of an automobile and includes a light emitting unit (light source) such as an LED, the translucent light that surrounds the electric switch fixed to the substrate and the LED over the entire circumference. The switch knob (switching member) of the nature presses the electrical switch to electrically connect and disconnect the air conditioner and the LED.

そして、枠状に形成されたケース(フレーム部材)の内側にスイッチノブを配置し、ケース側から内部に向けて突出するレール(レール部)が、スイッチノブ側から外部に向けて突出するスライダ(係合部)と嵌合して摺動案内する構造が採用されている(特許文献1参照)。これによれば、ケース側のレールとスイッチノブ側のスライダとの相互間隔を小さくし、レールに沿ってスライダを摺動させることによって電気スイッチをがたつきなく円滑に切り替え(断続)操作できる。   Then, a switch knob is arranged inside a case (frame member) formed in a frame shape, and a rail (rail portion) that protrudes from the case side toward the inside is a slider (rail portion) that protrudes from the switch knob side toward the outside. A structure that is fitted and engaged with the engaging portion) is employed (see Patent Document 1). According to this, the electrical switch can be smoothly switched (interrupted) without rattling by reducing the mutual distance between the rail on the case side and the slider on the switch knob side and sliding the slider along the rail.

ところで、このような押圧式スイッチにおいて、図9(a),(b)に矢印で示すように、ケース101をブラケット101aを介して車体(本体)側に取り付ける際にケース101に機械的変形(機械的歪)を生じたり、車体取り付け後に室内温度の変化等に伴ってケース101に熱的変形(熱的歪)を生じたりすることがある。すると、図9(c)に示すように、スイッチノブ110のスライダ111aがケース101のレール101bに沿って円滑に移動できなくなって、電気スイッチの操作性(操作フィーリング)が阻害される(悪化する)おそれがある。さらに極端な場合、スライダ111aの移動がロックされてしまうと、電気スイッチを誤作動させるおそれもある。特に自動車等の車両にあっては、走行時の振動によるケースの変形についても考慮する必要がある。   By the way, in such a push-type switch, as shown by arrows in FIGS. 9A and 9B, when the case 101 is attached to the vehicle body (main body) side via the bracket 101a, the case 101 is mechanically deformed ( Mechanical strain) may occur, or the case 101 may be thermally deformed (thermal strain) due to a change in room temperature after the vehicle body is attached. Then, as shown in FIG. 9C, the slider 111a of the switch knob 110 cannot move smoothly along the rail 101b of the case 101, and the operability (operation feeling) of the electric switch is hindered (deteriorated). There is a risk. In an extreme case, if the movement of the slider 111a is locked, the electric switch may malfunction. Particularly in vehicles such as automobiles, it is necessary to consider the deformation of the case due to vibration during travel.

本発明の課題は、係合部がレール部に沿って円滑に移動できるように構成することにより、取付時の機械的変形や取付後の熱的変形がケース体に生じた場合にもスイッチング部材の良好な操作性を維持できるプッシュ式スイッチ装置を提供することにある。   It is an object of the present invention to provide a switching member even when mechanical deformation at the time of mounting or thermal deformation after mounting occurs in the case body by configuring the engaging portion to move smoothly along the rail portion. It is an object of the present invention to provide a push-type switch device that can maintain good operability.

In addition, in order to solve the above problems, the push switch device of the present invention is
A peripheral wall portion that surrounds the electric switch and the light source fixed to the substrate over the entire circumference, presses the electric switch to electrically connect and disconnect the predetermined operating portion and the light source, and outward from the peripheral wall portion. A translucent switching member having an engaging portion protruding toward the surface;
A rail portion is formed on the inner side to be fitted in the engaging portion of the switching member to slide and guide the electric switch, and is arranged to surround the entire outer periphery of the switching member. A plurality of connecting frame portions for connecting the main frame portion to a box-shaped case body located outside in a form including a main frame portion and a strain absorbing portion formed to be more easily elastically deformed than the main frame portion. A frame member having
Equipped with a,
The connecting frame portion and the strain absorbing portion are formed in a plate shape that is continuous in a direction in which the electric switch is pressed in the case body .

このように、フレーム部材は、スイッチング部材(例えばスイッチノブ)の外側に配置される主フレーム部と、主フレーム部を箱状のケース体に対して接続する連結フレーム部とを含んで構成される。そして、主フレーム部の内側には、スイッチング部材の周壁部に形成された係合部(例えばスライダ)と嵌合して摺動案内するレール部が形成され、連結フレーム部には、主フレーム部よりも弾性変形しやすい歪吸収部が形成される。これによって、ケース体を車体(本体)に取り付ける際にケース体に機械的変形(機械的歪)を生じたり、車体取り付け後に室内温度の変化等に伴ってケース体に熱的変形(熱的歪)を生じたりしても、連結フレーム部の歪吸収部が弾性変形してケース体の変形(歪)を吸収する。したがって、ケース体の変形(歪)は係合部とレール部との嵌合部に伝わる前に歪吸収部で吸収され、係合部がレール部に沿って円滑に移動でき、スイッチング部材の良好な操作性を維持できる。   As described above, the frame member includes the main frame portion disposed outside the switching member (for example, the switch knob) and the connecting frame portion that connects the main frame portion to the box-shaped case body. . A rail portion is formed inside the main frame portion for sliding and guiding with an engaging portion (for example, a slider) formed on the peripheral wall portion of the switching member. The main frame portion is formed on the connecting frame portion. Thus, a strain absorbing portion that is more elastically deformed is formed. As a result, mechanical deformation (mechanical strain) occurs in the case body when the case body is attached to the vehicle body (main body), or thermal deformation (thermal distortion) occurs in the case body due to changes in room temperature after the vehicle body is attached. ), The strain absorbing portion of the connecting frame portion is elastically deformed to absorb the deformation (strain) of the case body. Therefore, the deformation (distortion) of the case body is absorbed by the strain absorbing portion before being transmitted to the fitting portion between the engaging portion and the rail portion, and the engaging portion can move smoothly along the rail portion, and the switching member is excellent. Operability can be maintained.

しかも、主フレーム部がスイッチング部材の外側に全周にわたり取り囲むように配置され、連結フレーム部が主フレーム部とケース体とを接続する場合には、電気スイッチへの異物の侵入を防止し、プッシュ式スイッチ装置全体の剛性を高めることができる。また、照光型スイッチでは、夜間走行時の光源(例えばLED等の発光部)からの照明光漏れも防止できる。   In addition, when the main frame portion is arranged so as to surround the entire periphery of the switching member and the connecting frame portion connects the main frame portion and the case body, it prevents the entry of foreign matter into the electric switch and pushes the switch. The rigidity of the whole type switch device can be increased. The illuminated switch can also prevent leakage of illumination light from a light source (for example, a light emitting unit such as an LED) during night driving.

さらに、自動車等の車両に搭載する場合には、走行時の振動によりケース体に機械的変形(機械的歪)を生じても、上記と同様に連結フレーム部の歪吸収部が弾性変形してケース体の変形(歪)を吸収する。このようにして、取付時や取付後に機械的変形や熱的変形がケース体に生じた場合にも、スイッチング部材の操作性が良好に維持される。   Furthermore, when mounted on a vehicle such as an automobile, even if mechanical deformation (mechanical strain) occurs in the case body due to vibration during traveling, the strain absorbing portion of the connecting frame portion is elastically deformed in the same manner as described above. Absorbs deformation (distortion) of the case body. In this way, the operability of the switching member is well maintained even when mechanical deformation or thermal deformation occurs in the case body during or after mounting.

つまり、連結フレーム部の歪吸収部は、ケース体に歪を生じたときに、主フレーム部の弾性変形量よりも大きな弾性変形量を発生することになる。そのためには、歪吸収部や主フレーム部の形状、材質等を工夫して、歪吸収部の弾性率(ヤング率又は曲げ弾性率)が主フレーム部の弾性率よりも大であればよいことになる。   In other words, the strain absorbing portion of the connecting frame portion generates an elastic deformation amount larger than the elastic deformation amount of the main frame portion when the case body is distorted. To that end, the shape and material of the strain absorbing part and the main frame part should be devised so that the elastic modulus (Young's modulus or flexural modulus) of the strain absorbing part is larger than the elastic modulus of the main frame part. become.

具体的には、連結フレーム部を電気スイッチ押圧方向に連続する板状に形成し、歪吸収部を、連結フレーム部においてケース体との接続方向中間部に形成された薄肉部で構成することができる。このように歪吸収部を薄肉部で構成することにより、きわめて容易に歪吸収部を主フレーム部よりも弾性変形しやすくすることができる。   Specifically, the connecting frame portion may be formed in a plate shape that is continuous in the direction of pressing the electric switch, and the strain absorbing portion may be formed of a thin portion formed in the connecting frame portion at the intermediate portion in the connecting direction with the case body. it can. By configuring the strain absorbing portion with a thin portion in this way, the strain absorbing portion can be more easily elastically deformed than the main frame portion.

また、連結フレーム部を電気スイッチ押圧方向に連続する板状に形成し、歪吸収部を、連結フレーム部においてケース体との接続方向に対して連続的に又は断続的に屈曲する屈曲部で構成することができる。このように歪吸収部を屈曲部で構成することにより、きわめて容易に歪吸収部を主フレーム部よりも弾性変形しやすくすることができる。なお、屈曲部は、接続方向に対して連続的に屈曲するS字状に形成したり、接続方向に対して断続的に屈曲するクランク状(コの字状)や横向きV字状(くの字状)に形成したりすればよい。   Further, the connecting frame part is formed in a plate shape continuous in the electric switch pressing direction, and the strain absorbing part is configured by a bent part that bends continuously or intermittently with respect to the connecting direction with the case body in the connecting frame part. can do. By configuring the strain absorbing portion as a bent portion in this manner, the strain absorbing portion can be more easily elastically deformed than the main frame portion. The bent portion is formed in an S-shape that bends continuously in the connection direction, a crank shape that is intermittently bent in the connection direction (a U-shape), or a lateral V-shape ( Or the like).

さらに、連結フレーム部と主フレーム部とを電気スイッチ押圧方向に連続する板状にそれぞれ形成するとともに、歪吸収部を含む連結フレーム部全体を主フレーム部よりも薄肉状に構成することができる。このように連結フレーム部全体を薄肉状に構成することにより、きわめて容易に歪吸収部を主フレーム部よりも弾性変形しやすくすることができる。   Further, the connecting frame part and the main frame part can be formed in a plate shape continuous in the electric switch pressing direction, respectively, and the entire connecting frame part including the strain absorbing part can be formed thinner than the main frame part. By configuring the entire connecting frame portion in this manner, the strain absorbing portion can be more easily elastically deformed than the main frame portion.

そして、連結フレーム部を、電気スイッチを押圧する方向に連続する板状に形成するとともに、歪吸収部を含む全体を主フレーム部よりも剛性率の低い材質で構成することができる。このように連結フレーム部全体を剛性率の低い材質で構成することにより、きわめて容易に歪吸収部を主フレーム部よりも弾性変形しやすくすることができる。その際、主フレーム部を金属材料、連結フレーム部を高分子材料で構成したり、主フレーム部と連結フレーム部とを、剛性率の異なる高分子材料で構成したりしてもよい。なお、高分子材料にはプラスチック(合成樹脂)とエラストマー(合成ゴム)とを含む。   The connecting frame portion can be formed in a plate shape continuous in the direction of pressing the electric switch, and the entire structure including the strain absorbing portion can be made of a material having a lower rigidity than the main frame portion. Thus, by constituting the whole connecting frame part with a material having a low rigidity, the strain absorbing part can be more easily elastically deformed than the main frame part. At this time, the main frame part may be made of a metal material and the connecting frame part may be made of a polymer material, or the main frame part and the connecting frame part may be made of polymer materials having different rigidity. The polymer material includes plastic (synthetic resin) and elastomer (synthetic rubber).

(実施例1)
以下、本発明の実施の形態につき図面に示す実施例を参照して説明する。図1は本発明に係るプッシュ式照光型スイッチ装置の一例を示す正面図、図2はその要部斜視図である。図1及び図2に示すプッシュ式照光型スイッチ装置100(プッシュ式スイッチ装置)は、自動車のエアコンディション表示パネル部等の車体(本体)側(図示せず)に搭載されて、LED4等の発光部(光源)を内部に含む照光型の押圧式スイッチである。このプッシュ式照光型スイッチ装置(以下、単にスイッチ装置ともいう)100は、ブラケット1aを介して車体(本体)側に取り付けられる箱型(例えば直方体状)のケース1(ケース体)を有し、ケース1にはスイッチング部材としての透光性(例えば透明)のスイッチノブ10とフレーム部材としての支持枠20とが収容されている。
Example 1
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 is a front view showing an example of a push-type illuminated switch device according to the present invention, and FIG. A push-type illuminated switch device 100 (push-type switch device) shown in FIG. 1 and FIG. 2 is mounted on a vehicle body (main body) side (not shown) such as an air-conditioning display panel of an automobile, and emits light from an LED 4 or the like. It is an illumination type push-type switch including a portion (light source) inside. This push-type illuminated switch device (hereinafter also simply referred to as a switch device) 100 has a box-shaped (for example, rectangular parallelepiped) case 1 (case body) attached to the vehicle body (main body) via a bracket 1a. The case 1 accommodates a translucent (for example, transparent) switch knob 10 as a switching member and a support frame 20 as a frame member.

スイッチノブ10は、四隅にアール部が形成されかつ上端部を幅狭に形成された擬似矩形形状(図1参照)を有するとともに、プリント基板2(基板)に固定された1又は複数(例えば左右一対)の電気スイッチ3と1又は複数(例えば1個)のLED4とを全周にわたり囲む周壁部11を有している。このスイッチノブ10が電気スイッチ3を押圧することによって、空気調和装置(作動部;図示せず)及びLED4が電気的に断続(切入)される。また、スイッチノブ10の周壁部11において、1又は複数ヶ所(例えば3ヶ所)から外方(電気スイッチ3の位置する側とは反対側)に向けて矩形板状のスライダ11a(係合部)が電気スイッチ3の押圧方向に沿って連続的に突出形成されている。   The switch knob 10 has a pseudo-rectangular shape (see FIG. 1) in which rounded portions are formed at four corners and the upper end portion is narrow, and one or a plurality (for example, left and right) fixed to the printed circuit board 2 (board). The peripheral wall part 11 which surrounds a pair of electrical switch 3 and 1 or several (for example, 1 piece) LED4 over a perimeter. When the switch knob 10 presses the electric switch 3, the air conditioner (operating unit; not shown) and the LED 4 are electrically connected (cut). Further, in the peripheral wall portion 11 of the switch knob 10, a rectangular plate-like slider 11a (engagement portion) is directed from one or a plurality of locations (for example, three locations) to the outside (the side opposite to the side where the electrical switch 3 is located). Is formed so as to continuously protrude along the pressing direction of the electric switch 3.

支持枠20は、スイッチノブ10の外側を全周にわたって矩形状に取り囲むように配置される矩形枠21(主フレーム部)と、その矩形枠21を複数ヶ所(例えば6ヶ所)でケース1に接続する連結枠22(連結フレーム部)とを有する。矩形枠21は電気スイッチ3の押圧方向に沿って連続する枠状に形成され、連結枠22は電気スイッチ3の押圧方向に沿って連続する板状に形成されている。   The support frame 20 is connected to the case 1 at a rectangular frame 21 (main frame portion) arranged so as to surround the outside of the switch knob 10 in a rectangular shape over the entire circumference, and the rectangular frame 21 at a plurality of locations (for example, 6 locations). Connecting frame 22 (connecting frame portion). The rectangular frame 21 is formed in a frame shape continuous along the pressing direction of the electric switch 3, and the connecting frame 22 is formed in a plate shape continuous along the pressing direction of the electric switch 3.

そして、矩形枠21の内側には、スイッチノブ10の各スライダ11aを両側から挟むように嵌合して摺動案内する矩形板状の一対のレール21a(レール部)が、1対又は複数対(例えば3対)電気スイッチ3の押圧方向に沿って連続的に突出形成されている。一方、連結枠22の中間部には、矩形枠21よりも弾性変形しやすく形成された歪吸収部22aが、電気スイッチ3の押圧方向に沿って連続する板状に形成されている。具体的には図2に示すように、矩形枠21をケース1に連結する上下の連結枠22の接続方向中間部に、歪吸収部22aを構成する薄肉部がそれぞれ形成されている。   Inside the rectangular frame 21, a pair or a plurality of pairs of rectangular plates 21a (rail portions) are fitted and slidably guided so as to sandwich the sliders 11a of the switch knob 10 from both sides. (For example, three pairs) The electric switch 3 is formed so as to continuously protrude along the pressing direction. On the other hand, a strain absorbing portion 22 a that is more easily elastically deformed than the rectangular frame 21 is formed in an intermediate portion of the connecting frame 22 in a plate shape that is continuous along the pressing direction of the electric switch 3. Specifically, as shown in FIG. 2, a thin portion constituting the strain absorbing portion 22 a is formed at an intermediate portion in the connecting direction of the upper and lower connecting frames 22 that connect the rectangular frame 21 to the case 1.

このように、連結枠22には薄肉部22aが形成されている。これによって、図3に示すように、ケース1を車体(本体)に取り付ける際にケース1に機械的変形(機械的歪)を生じたり、車体取り付け後に室内温度の変化等に伴ってケース1に熱的変形(熱的歪)を生じたり、走行時の振動によりケース1に機械的変形(機械的歪)を生じたりしたときに、連結枠22の薄肉部22aは、矩形枠21の弾性変形量(弾性歪)よりも大きな弾性変形量(弾性歪)を発生する。つまり、ケース1が変形した方向(図3矢印方向)に連結枠22の薄肉部22aが撓んで弾性変形することによって、連結枠22がケース1の変形(歪)を吸収することができる。その結果、レール21a(矩形枠21)とスライダ11a(スイッチノブ10)との相互位置関係はケース1の変形にはほとんど影響されなくなるので、スライダ11aがレール21aに沿って円滑に移動でき、スイッチノブ10の操作性を良好に維持できる。   Thus, the connection frame 22 is formed with a thin portion 22a. As a result, as shown in FIG. 3, when the case 1 is attached to the vehicle body (main body), the case 1 is mechanically deformed (mechanical strain), or after the vehicle body is attached, When thermal deformation (thermal strain) occurs or mechanical deformation (mechanical strain) occurs in the case 1 due to vibration during traveling, the thin-walled portion 22a of the connecting frame 22 is elastically deformed of the rectangular frame 21. An elastic deformation amount (elastic strain) larger than the amount (elastic strain) is generated. That is, the thin portion 22a of the connecting frame 22 is bent and elastically deformed in the direction in which the case 1 is deformed (arrow direction in FIG. 3), so that the connecting frame 22 can absorb the deformation (distortion) of the case 1. As a result, the mutual positional relationship between the rail 21a (rectangular frame 21) and the slider 11a (switch knob 10) is hardly affected by the deformation of the case 1, so that the slider 11a can move smoothly along the rail 21a, and the switch The operability of the knob 10 can be maintained well.

しかも、矩形枠21がスイッチノブ10の外側を全周にわたり取り囲むように配置され、連結枠22が矩形枠21とケース1とを接続する状態は、連結枠22に薄肉部22aが形成されても何ら変わりがない。したがって、矩形枠21や連結枠22によって、電気スイッチ3への異物の侵入を防止し、スイッチ装置100全体の剛性を高めることができ、夜間走行時にLED4からの照明光漏れも防止できる。   Moreover, the rectangular frame 21 is arranged so as to surround the outside of the switch knob 10 over the entire circumference, and the connecting frame 22 connects the rectangular frame 21 and the case 1 even when the thin portion 22a is formed on the connecting frame 22. There is no change. Therefore, the rectangular frame 21 and the connecting frame 22 can prevent foreign matter from entering the electrical switch 3, increase the rigidity of the switch device 100 as a whole, and prevent illumination light leakage from the LED 4 during night driving.

なお、ケース1と支持枠20とは合成樹脂(例えばABS樹脂)の射出一体成形によって形成することができ、スイッチノブ10の操作性を良好に維持しつつスイッチ装置100の製造コストを低減できる。   The case 1 and the support frame 20 can be formed by injection molding of synthetic resin (for example, ABS resin), and the manufacturing cost of the switch device 100 can be reduced while maintaining the operability of the switch knob 10 well.

(実施例2)
次に、本発明に係るプッシュ式照光型スイッチ装置の他の例を図4に示す。図4に示す連結枠22(連結フレーム部)も電気スイッチ3(図1参照)の押圧方向に沿って連続する板状に形成され、連結枠22の中間部には、矩形枠21(主フレーム部)よりも弾性変形しやすく形成された歪吸収部22bが形成されている。具体的には、矩形枠21をケース1(ケース体)に連結する上下の連結枠22の接続方向中間部に、接続方向に対してS字状に連続的に屈曲する屈曲部が歪吸収部22bとしてそれぞれ形成されている。
(Example 2)
Next, FIG. 4 shows another example of the push type illumination type switching device according to the present invention. 4 is also formed in a plate shape that continues along the pressing direction of the electrical switch 3 (see FIG. 1), and a rectangular frame 21 (main frame) is formed in the middle of the connection frame 22. The strain absorbing portion 22b is formed so as to be more easily elastically deformed than the portion). Specifically, a bending portion that continuously bends in an S shape with respect to the connection direction is provided at the intermediate portion in the connection direction of the upper and lower connection frames 22 that connect the rectangular frame 21 to the case 1 (case body). 22b is formed.

このように、図4の連結枠22には連続的に屈曲する屈曲部22bが形成されている。これによって、図3(実施例1)と同様に、ケース1が変形した方向(図3矢印方向)に連結枠22の屈曲部22bが撓んで弾性変形することによって、連結枠22がケース1の変形(歪)を吸収することができる。その結果、レール21a(レール部)とスライダ11a(係合部)との相互位置関係はケース1の変形にはほとんど影響されなくなるので、スライダ11aがレール21aに沿って円滑に移動でき、スイッチノブ10(スイッチング部材)の操作性を良好に維持できる。   As described above, the connecting frame 22 of FIG. 4 is formed with a bent portion 22b that is continuously bent. As a result, similarly to FIG. 3 (Embodiment 1), the bent portion 22b of the connecting frame 22 is bent and elastically deformed in the direction in which the case 1 is deformed (the direction of the arrow in FIG. 3). Deformation (strain) can be absorbed. As a result, the mutual positional relationship between the rail 21a (rail portion) and the slider 11a (engagement portion) is hardly affected by the deformation of the case 1, so that the slider 11a can move smoothly along the rail 21a and the switch knob. The operability of 10 (switching member) can be maintained well.

なお、連続的に屈曲する屈曲部22bとして、S字状以外に湾曲状(カーブ状)、つづら折れ状(ヘアピンカーブ状)、螺旋状(つるまき状)等であってもよい。また、図4(実施例2)において図1〜図3(実施例1)と共通する機能を有する部分には同一符号を付して説明を省略する。   The bent portion 22b that bends continuously may have a curved shape (curve shape), a zigzag shape (hairpin curve shape), a spiral shape (spiral shape), etc. in addition to the S-shape.

本発明に係るプッシュ式照光型スイッチ装置のさらに他の例を図5及び図6に示す。図5及び図6に示す連結枠22(連結フレーム部)も電気スイッチ3(図1参照)の押圧方向に沿って連続する板状に形成され、連結枠22の中間部には、矩形枠21(主フレーム部)よりも弾性変形しやすく形成された歪吸収部22c,22dが形成されている。具体的には、図5では、矩形枠21をケース1(ケース体)に連結する上下の連結枠22の接続方向中間部に、接続方向に対して横向きV字状(くの字状)に断続的に屈曲する屈曲部が歪吸収部22cとしてそれぞれ形成されている。また、図6では、上下の連結枠22の接続方向中間部に、接続方向に対してクランク状(コの字状)に断続的に屈曲する屈曲部が歪吸収部22dとしてそれぞれ形成されている。
(Example 3)
Still another example of the push type illumination type switching device according to the present invention is shown in FIGS. The connection frame 22 (connection frame portion) shown in FIGS. 5 and 6 is also formed in a plate shape that continues along the pressing direction of the electric switch 3 (see FIG. 1). Strain absorbing portions 22c and 22d are formed that are more easily elastically deformed than the (main frame portion). Specifically, in FIG. 5, the rectangular frame 21 is formed in a V-shaped (cube-shaped) sideways with respect to the connecting direction at the intermediate portion in the connecting direction of the upper and lower connecting frames 22 that connect the case 1 (case body). Bending portions that bend intermittently are formed as strain absorbing portions 22c, respectively. Further, in FIG. 6, bent portions that are bent in a crank shape (a U-shape) intermittently with respect to the connection direction are formed as strain absorbing portions 22 d at intermediate portions in the connection direction of the upper and lower connecting frames 22. .

このように、図5,図6の連結枠22には断続的に屈曲する屈曲部22c,22dが形成されている。これによって、図3(実施例1)と同様に、ケース1が変形した方向(図3矢印方向)に連結枠22の屈曲部22c,22dが撓んで弾性変形することによって、連結枠22がケース1の変形(歪)を吸収することができる。その結果、レール21a(レール部)とスライダ11a(係合部)との相互位置関係はケース1の変形にはほとんど影響されなくなるので、スライダ11aがレール21aに沿って円滑に移動でき、スイッチノブ10(スイッチング部材)の操作性を良好に維持できる。   As described above, the connecting frame 22 shown in FIGS. 5 and 6 is formed with bent portions 22c and 22d which are bent intermittently. As a result, similarly to FIG. 3 (Example 1), the bent portions 22c and 22d of the connecting frame 22 are bent and elastically deformed in the direction in which the case 1 is deformed (arrow direction in FIG. 3), so that the connecting frame 22 is deformed. 1 deformation (strain) can be absorbed. As a result, the mutual positional relationship between the rail 21a (rail portion) and the slider 11a (engagement portion) is hardly affected by the deformation of the case 1, so that the slider 11a can move smoothly along the rail 21a and the switch knob. The operability of 10 (switching member) can be maintained well.

なお、断続的に屈曲する屈曲部22c,22dとして、V字状、クランク状以外の形状であってもよい。また、図5・図6(実施例3)において図1〜図3(実施例1)と共通する機能を有する部分には同一符号を付して説明を省略する。   Note that the bent portions 22c and 22d that bend intermittently may have shapes other than the V shape and the crank shape. 5 and 6 (Embodiment 3), parts having the same functions as those in FIGS. 1 to 3 (Embodiment 1) are denoted by the same reference numerals, and the description thereof is omitted.

(実施例4)
本発明に係るプッシュ式照光型スイッチ装置のさらに他の例を図7に示す。図7に示す連結枠22’(連結フレーム部)と矩形枠21(主フレーム部)とは電気スイッチ3(図1参照)の押圧方向に沿って連続する板状にそれぞれ形成され、連結枠22’の全体が矩形枠21よりも弾性変形しやすく形成されている。具体的には、矩形枠21をケース1(ケース体)に連結する上下の連結枠22’の全体が、歪吸収部として矩形枠21よりも薄肉状にそれぞれ形成されている。
Example 4
FIG. 7 shows still another example of the push type illumination type switching device according to the present invention. The connection frame 22 ′ (connection frame portion) and the rectangular frame 21 (main frame portion) shown in FIG. 7 are respectively formed in a plate shape that is continuous along the pressing direction of the electric switch 3 (see FIG. 1). 'Is formed so as to be more easily elastically deformed than the rectangular frame 21. Specifically, the entire upper and lower connecting frames 22 ′ that connect the rectangular frame 21 to the case 1 (case body) are formed thinner than the rectangular frame 21 as strain absorbing portions.

このように、図7の薄肉状の連結枠22’は全体が歪吸収部として構成されている。これによって、図3(実施例1)と同様に、ケース1が変形した方向(図3矢印方向)に薄肉状の連結枠22’が撓んで弾性変形することによって、連結枠22’がケース1の変形(歪)を吸収することができる。その結果、レール21a(レール部)とスライダ11a(係合部)との相互位置関係はケース1の変形にはほとんど影響されなくなるので、スライダ11aがレール21aに沿って円滑に移動でき、スイッチノブ10(スイッチング部材)の操作性を良好に維持できる。   As described above, the thin connection frame 22 ′ of FIG. 7 is configured as a strain absorbing portion as a whole. As a result, similarly to FIG. 3 (Example 1), the thin connecting frame 22 ′ is bent and elastically deformed in the direction in which the case 1 is deformed (the arrow direction in FIG. 3), so that the connecting frame 22 ′ becomes the case 1. Can be absorbed. As a result, the mutual positional relationship between the rail 21a (rail portion) and the slider 11a (engagement portion) is hardly affected by the deformation of the case 1, so that the slider 11a can move smoothly along the rail 21a and the switch knob. The operability of 10 (switching member) can be maintained well.

なお、連結枠22’の厚さは、矩形枠21よりも薄肉状であれば、接続方向に対して連続的に又は断続的に変化してもよい。また、図7(実施例4)において図1〜図3(実施例1)と共通する機能を有する部分には同一符号を付して説明を省略する。   Note that the thickness of the connecting frame 22 ′ may change continuously or intermittently with respect to the connection direction as long as it is thinner than the rectangular frame 21. Further, in FIG. 7 (Embodiment 4), parts having the same functions as those in FIGS.

(実施例5)
本発明に係るプッシュ式照光型スイッチ装置のさらに他の例を図8に示す。図8に示す連結枠22”(連結フレーム部)と矩形枠21(主フレーム部)とは電気スイッチ3(図1参照)の押圧方向に沿って連続する板状にそれぞれ形成され、連結枠22”の全体が矩形枠21よりも弾性変形しやすく形成されている。具体的には、矩形枠21をケース1(ケース体)に連結する上下の連結枠22”の全体が、歪吸収部として矩形枠21よりも剛性率の低い材質でそれぞれ構成されている。例えば、矩形枠21を銅等の金属材料、連結枠22”をABS樹脂等の合成樹脂材料で構成したり、矩形枠21をABS樹脂等の合成樹脂材料、連結枠22”をシリコーンゴム等の合成ゴム材料で構成したりすることができる。
(Example 5)
FIG. 8 shows still another example of the push type illumination type switching device according to the present invention. The connecting frame 22 ″ (connecting frame portion) and the rectangular frame 21 (main frame portion) shown in FIG. 8 are respectively formed in a plate shape continuous along the pressing direction of the electric switch 3 (see FIG. 1). "Is formed so as to be elastically deformed more easily than the rectangular frame 21. Specifically, the entire upper and lower connecting frames 22 ″ for connecting the rectangular frame 21 to the case 1 (case body) are each made of a material having a lower rigidity than the rectangular frame 21 as a strain absorbing portion. The rectangular frame 21 is made of a metal material such as copper, the connecting frame 22 ″ is made of a synthetic resin material such as ABS resin, the rectangular frame 21 is made of a synthetic resin material such as ABS resin, and the connecting frame 22 ″ is made of a synthetic material such as silicone rubber. Or a rubber material.

このように、図8の低剛性率の連結枠22”は全体が歪吸収部として構成されている。これによって、図3(実施例1)と同様に、ケース1が変形した方向(図3矢印方向)に低剛性率の連結枠22”が撓んで弾性変形することによって、連結枠22”がケース1の変形(歪)を吸収することができる。その結果、レール21a(レール部)とスライダ11a(係合部)との相互位置関係はケース1の変形にはほとんど影響されなくなるので、スライダ11aがレール21aに沿って円滑に移動でき、スイッチノブ10(スイッチング部材)の操作性を良好に維持できる。   As described above, the entire connecting frame 22 ″ having a low rigidity ratio in FIG. 8 is configured as a strain absorbing portion. Thus, as in FIG. 3 (Example 1), the direction in which the case 1 is deformed (FIG. 3). When the connecting frame 22 ″ having a low rigidity is bent and elastically deformed in the direction of the arrow, the connecting frame 22 ″ can absorb the deformation (distortion) of the case 1. As a result, the rail 21a (rail portion) and Since the mutual positional relationship with the slider 11a (engagement portion) is hardly affected by the deformation of the case 1, the slider 11a can move smoothly along the rail 21a, and the operability of the switch knob 10 (switching member) is excellent. Can be maintained.

なお、連結枠22”と矩形枠21とは、インサート成形(矩形枠21を金属材料製とする場合)、二色成形(両者を高分子材料製とする場合)等の射出一体成形によって形成することができ、スイッチノブ10の操作性を良好に維持しつつスイッチ装置100の製造コストを低減できる。また、図8(実施例5)において図1〜図3(実施例1)と共通する機能を有する部分には同一符号を付して説明を省略する。   The connecting frame 22 ″ and the rectangular frame 21 are formed by injection integral molding such as insert molding (when the rectangular frame 21 is made of a metal material) or two-color molding (when both are made of a polymer material). The manufacturing cost of the switch device 100 can be reduced while maintaining the operability of the switch knob 10 well, and the functions common to FIGS. 1 to 3 (Embodiment 1) in FIG. The same reference numerals are given to the portions having, and the description is omitted.

以上で説明した歪吸収部22a,22b,22c,22d,22’,22”について、各実施例の構成を複数組み合わせて実施してもよい。例えば、図2(実施例1)において、歪吸収部22a(連結枠22)をシリコーンゴムで構成し、矩形枠21をABS樹脂で構成してもよい。このように、各実施例の構成を複数組み合わせて実施することによって、連結枠22によるケース1の変形(歪)吸収効果が相乗的に発揮される。   The strain absorbing portions 22a, 22b, 22c, 22d, 22 ′, and 22 ″ described above may be implemented by combining a plurality of configurations of each example. For example, in FIG. 2 (Example 1), strain absorption is performed. The portion 22a (connecting frame 22) may be made of silicone rubber, and the rectangular frame 21 may be made of ABS resin. 1 deformation (strain) absorption effect is exhibited synergistically.
