Description

本発明は、主に各種電子機器の操作に使用される可動接点体及びこれを用いたスイッチに関するものである。   The present invention relates to a movable contact body mainly used for operation of various electronic devices and a switch using the same.

近年、各種電子機器、特に携帯電話等の携帯端末機器においては、周囲が暗い場合でも、押釦や表示シート等の識別や操作が容易に行えるように、発光ダイオードやＥＬ素子等を発光させて操作部の照光を行うものが増えており、これらの機器に用いられる可動接点体やスイッチにも、使い易く多様な照光を行えるものが求められている。   In recent years, various electronic devices, particularly mobile terminal devices such as mobile phones, are operated by emitting light emitting diodes or EL elements so that push buttons and display sheets can be easily identified and operated even when the surroundings are dark. There are an increasing number of parts that illuminate parts, and movable contact bodies and switches used in these devices are also required to be easy to use and capable of various kinds of illumination.

このような従来の可動接点体やこれを用いたスイッチについて、図４を用いて説明する。   Such a conventional movable contact body and a switch using the same will be described with reference to FIG.

なお、この図面は構成を判り易くするために、部分的に寸法を拡大して表している。   In addition, in this drawing, in order to make the configuration easy to understand, the dimensions are partially enlarged.

図４は従来のスイッチの断面図であり、同図において、１は光透過性でフィルム状の基材で、この基材１上面には、凹凸状に形成された複数の発光部２が設けられて、導光シート３が形成されている。   FIG. 4 is a cross-sectional view of a conventional switch. In FIG. 4, reference numeral 1 denotes a light-transmitting film-like base material, and a plurality of light emitting portions 2 formed in an uneven shape are provided on the upper surface of the base material 1. Thus, the light guide sheet 3 is formed.

そして、４は略ドーム状で導電金属薄板製の可動接点で、複数の可動接点４が発光部２下方の導光シート３下面に貼付されて、可動接点体５が構成されている。   Reference numeral 4 denotes a movable contact made of a conductive metal thin plate having a substantially dome shape, and a plurality of movable contacts 4 are attached to the lower surface of the light guide sheet 3 below the light emitting unit 2 to constitute a movable contact body 5.

また、６は上下面に複数の配線パターン（図示せず）が形成された配線基板で、上面には略円形状の中央固定接点７Ａと、これを囲む略馬蹄状または略リング状の外側固定接点７Ｂから形成された、複数の固定接点対７が設けられている。   Reference numeral 6 denotes a wiring board having a plurality of wiring patterns (not shown) formed on the upper and lower surfaces, and a substantially circular central fixed contact 7A on the upper surface and a substantially horseshoe-shaped or substantially ring-shaped outer fixed surrounding the same. A plurality of fixed contact pairs 7 formed from the contacts 7B are provided.

さらに、この配線基板６上面に可動接点体５が、各々の可動接点４の外周が外側固定接点７Ｂ上に載置され、可動接点４の下面中央が中央固定接点７Ａと所定の間隙を空けて、対向するように貼付されている。   Further, the movable contact body 5 is placed on the upper surface of the wiring board 6, the outer periphery of each movable contact 4 is placed on the outer fixed contact 7B, and the center of the lower surface of the movable contact 4 is spaced from the central fixed contact 7A by a predetermined gap. , Are affixed to face each other.

そして、８は発光ダイオード等の発光素子で、複数の発光素子８が導光シート３側方の配線基板６上面に実装され、例えば基材１の右端面に発光面を向けて配置されている。   Reference numeral 8 denotes a light emitting element such as a light emitting diode, and a plurality of light emitting elements 8 are mounted on the upper surface of the wiring substrate 6 on the side of the light guide sheet 3, and are arranged with the light emitting surface facing the right end surface of the substrate 1, for example. .

また、９は光透過性でフィルム状の表示シートで、全面に印刷等によって形成された遮光部９Ａの所定箇所が、文字や記号等の形状にくり抜かれて複数の表示部９Ｂが形成され、可動接点体５上方に貼付されて、スイッチが構成されている。   Further, 9 is a light-transmitting film-like display sheet, and a predetermined portion of the light-shielding portion 9A formed by printing or the like on the entire surface is cut out into a shape such as a character or a symbol to form a plurality of display portions 9B. A switch is configured by being affixed above the movable contact body 5.

そして、このように構成されたスイッチが、電子機器の操作面に装着されると共に、複数の中央固定接点７Ａや外側固定接点７Ｂ、複数の発光素子８が配線パターン等を介して、機器の電子回路（図示せず）に接続される。   The switch configured as described above is mounted on the operation surface of the electronic device, and the plurality of central fixed contacts 7A, the outer fixed contacts 7B, and the plurality of light emitting elements 8 are connected to the electronic device via the wiring pattern or the like. Connected to a circuit (not shown).

以上の構成において、表示シート９を下方へ押圧操作すると、導光シート３が撓んで可動接点４の略ドーム状の中央部が押圧され、所定の押圧力が加わると、可動接点４がクリック感を伴って下方へ弾性反転し、可動接点４の下面中央が中央固定接点７Ａに接触することによって、固定接点対７を構成する中央固定接点７Ａと外側固定接点７Ｂが、可動接点４を介して電気的に接続された状態となる。   In the above configuration, when the display sheet 9 is pressed downward, the light guide sheet 3 is bent and the substantially dome-shaped central portion of the movable contact 4 is pressed. When a predetermined pressing force is applied, the movable contact 4 is clicked. When the center of the lower surface of the movable contact 4 comes into contact with the central fixed contact 7A, the central fixed contact 7A and the outer fixed contact 7B constituting the fixed contact pair 7 are connected via the movable contact 4. It is in an electrically connected state.

ここで、表示シート９への押圧力を解除すると、弾性復帰力によって可動接点４が上方へ弾性反転し、可動接点４の下面中央が中央固定接点７Ａから離れて、中央固定接点７Ａと外側固定接点７Ｂが電気的に切断された状態となる。   Here, when the pressing force to the display sheet 9 is released, the movable contact 4 is elastically reversed upward by the elastic restoring force, and the center of the lower surface of the movable contact 4 is separated from the central fixed contact 7A, and the central fixed contact 7A and the outer fixed are fixed. The contact 7B is electrically disconnected.

つまり、表示シート９を下方へ押圧操作した際には、可動接点４が金属薄板で形成されているため、クリック感を伴って下方へ弾性反転することができ、また表示シート９への押圧力を解除した際に、可動接点４の弾性復帰力によって、元の状態に復帰するものとなっていた。   That is, when the display sheet 9 is pressed downward, since the movable contact 4 is formed of a thin metal plate, the display sheet 9 can be elastically reversed downward with a click feeling, and the pressing force applied to the display sheet 9 When the is released, the elastic contact force of the movable contact 4 restores the original state.

そして、このような固定接点対７の電気的接離に応じて、機器の各機能の切換えが行われると共に、機器の電子回路から発光素子８に電源が供給されると、複数の発光素子８が発光し、この光が右端面から導光シート３内に入射して、基材１内を反射しながら左方へ進む。   Then, according to the electrical contact / separation of the fixed contact pair 7, each function of the device is switched, and when power is supplied from the electronic circuit of the device to the light emitting element 8, the plurality of light emitting elements 8 are switched. Is emitted, and this light enters the light guide sheet 3 from the right end surface and proceeds to the left while reflecting inside the base material 1.

さらに、この光が基材１上面の複数の発光部２で拡散され反射して、表示シート９の表示部９Ｂを下方から照光し、複数の表示部９Ｂが照光されることによって、周囲が暗い場合でも、表示部９Ｂの文字や記号等の表示が識別でき、操作を容易に行うことが可能なようになるものであった。   Further, the light is diffused and reflected by the plurality of light emitting units 2 on the upper surface of the base material 1 to illuminate the display unit 9B of the display sheet 9 from below, and the plurality of display units 9B are illuminated, whereby the surroundings are dark. Even in this case, the display of characters, symbols and the like on the display unit 9B can be identified, and the operation can be easily performed.

なお、この出願の発明に関連する先行技術文献情報としては、例えば、特許文献１が知られている。   As prior art document information related to the invention of this application, for example, Patent Document 1 is known.

しかしながら、上記従来の可動接点体５においては、導光シート３に可動接点４を貼り付けて、押圧操作した際に良好なクリック感が得られるものとしていたが、この場合、可動接点４が必要なため、部品点数が多くなり効率的に製造することが困難であるという課題があった。   However, in the conventional movable contact body 5, the movable contact 4 is attached to the light guide sheet 3 and a good click feeling is obtained when the pressing operation is performed. In this case, the movable contact 4 is necessary. Therefore, there is a problem that the number of parts increases and it is difficult to manufacture efficiently.

本発明は、このような従来の課題を解決するものであり、効率的に製造が可能な可動接点体およびこれを用いたスイッチを提供することを目的とする。   The present invention solves such conventional problems, and an object thereof is to provide a movable contact body that can be efficiently manufactured and a switch using the same.

上記目的を達成するために本発明は、以下の構成を有するものである。   In order to achieve the above object, the present invention has the following configuration.

本発明の請求項１に記載の発明は、光透過性でフィルム状の基材にドーム状に盛り上がった複数のドーム部が設けられ、基材の厚みが、ドーム部の外縁部より頭頂部で厚く、ドーム部内壁面の少なくとも頭頂部裏面に導電塗料が塗布されて電極部が形成されて可動接点体を構成したものであり、外縁部より頭頂部のほうが基材の変形が小さいことで良好なクリック感を作り出せるため、基材の下方に別途金属薄板製などの可動接点を設ける必要が無くなり、部品点数が少なく効率的に製造が可能な可動接点体を得ることができるという作用を有する。   According to the first aspect of the present invention, a plurality of dome portions raised in a dome shape are provided on a light-transmitting film-like base material, and the thickness of the base material is greater than the outer edge portion of the dome portion at the top of the head. The electrode is formed by applying conductive paint on at least the back of the top surface of the inner wall surface of the dome part to form a movable contact body, and the top part is better because the deformation of the base material is smaller than the outer edge part. Since a click feeling can be created, there is no need to separately provide a movable contact made of a thin metal plate or the like below the base material, and it is possible to obtain a movable contact body that can be efficiently manufactured with a reduced number of parts.

請求項２に記載の発明は、請求項１記載の可動接点体の頭頂部上方に操作手段を備えてスイッチを構成したものであり、簡易な構成で、効率的に製造が可能なスイッチを得ることができるという作用を有する。   According to the second aspect of the present invention, the switch is configured by providing the operating means above the top of the movable contact body according to the first aspect, and a switch that can be efficiently manufactured with a simple configuration is obtained. It has the effect of being able to.

以上のように本発明によれば、効率的に製造が可能な可動接点体およびこれを用いたスイッチを実現することができるという有利な効果が得られる。   As described above, according to the present invention, an advantageous effect that a movable contact body that can be efficiently manufactured and a switch using the movable contact body can be realized.

以下、本発明の実施の形態について、図１から図３を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.

なお、これらの図面は構成を判り易くするために、部分的に寸法を拡大して表している。   These drawings are partially enlarged in size for easy understanding of the configuration.

また、背景技術の項で説明した構成と同一構成の部分には同一符号を付して、詳細な説明を簡略化する。   Further, the same reference numerals are given to the same components as those described in the background art section, and the detailed description will be simplified.

（実施の形態）
図１は本発明の一実施の形態による可動接点体の断面図であり、同図において、２１は０．２ｍｍ前後の厚みのフィルム状でポリウレタンやシリコーン、ポリスチレン、ポリカーボネート、ポリメタクリル酸メチル等の可撓性を有する光透過性の基材で、ドーム状に盛り上がった複数のドーム部２１Ａと平坦部２１Ｂから構成されると共に、ドーム部２１Ａ上面には粒径１０〜数百μｍ前後の凹凸状に形成された複数の発光部２２が設けられている。 (Embodiment)
FIG. 1 is a cross-sectional view of a movable contact body according to an embodiment of the present invention, in which 21 is a film having a thickness of about 0.2 mm, such as polyurethane, silicone, polystyrene, polycarbonate, polymethyl methacrylate, and the like. It is a light-transmitting base material having flexibility, and is composed of a plurality of dome portions 21A and flat portions 21B that are raised in a dome shape, and an uneven shape with a particle size of around 10 to several hundreds μm on the top surface of the dome portion 21A. A plurality of light-emitting portions 22 formed in is provided.

また、各ドーム部２１Ａは、基材２１の厚みが、ドーム部２１Ａの外周上方の外縁部２１Ｃより頭頂部２１Ｄで厚くなっており、頭頂部２１Ｄの断面は下方向に突出している。   In each dome portion 21A, the base material 21 is thicker at the top portion 21D than the outer edge portion 21C above the outer periphery of the dome portion 21A, and the cross section of the top portion 21D protrudes downward.

そして、基材２１下面には、直径１００〜数百ｎｍ程度の炭素銀などの微粒子を分散させた導電塗料３３が固定接点対３５と対向するドーム部２１Ａの内壁面に塗布され電極部２３が構成されている。   On the lower surface of the base material 21, a conductive paint 33 in which fine particles such as carbon silver having a diameter of about 100 to several hundred nm are dispersed is applied to the inner wall surface of the dome portion 21 </ b> A facing the fixed contact pair 35. It is configured.

さらに、２４はポリエチレンテレフタレート等のフィルム状のセパレータで、このセパレータ２４が基材２１下面全面を覆うように貼付され、保管・搬送時に電極部２３下面に塵埃等が付着しないようにして、可動接点体２５が構成されている。   Further, 24 is a film-like separator such as polyethylene terephthalate, which is affixed so as to cover the entire lower surface of the base material 21 so that dust or the like does not adhere to the lower surface of the electrode portion 23 during storage and transportation. A body 25 is constructed.

なお、このような可動接点体２５を製造する際には、図２の断面図において、まず、図２（ａ）の３１で示す金属製の下型と、３２で示す金属製の上型との間に、導電塗料３３を塗布したポリウレタンやシリコーン、ポリスチレン、ポリカーボネート、ポリメタクリル酸メチル等の光透過性樹脂の光学シート３４を載置する。   When manufacturing such a movable contact body 25, in the cross-sectional view of FIG. 2, first, a metal lower mold 31 shown in FIG. 2A and a metal upper mold 32 shown in FIG. In between, an optical sheet 34 of a light-transmitting resin such as polyurethane, silicone, polystyrene, polycarbonate, or polymethyl methacrylate coated with a conductive paint 33 is placed.

なお、下型３１には、複数のドーム状の窪み３１Ａが、その窪み３１Ａの底には複数の凹凸部３１Ｂが設けられており、また、上型３２には下方に凸となり中央部に円形孔３２Ａが設けられたドーム状の凸部３２Ｂが設けられている。   The lower mold 31 is provided with a plurality of dome-shaped depressions 31A, and the bottom of the depression 31A is provided with a plurality of concavo-convex parts 31B. A dome-shaped convex portion 32B provided with a hole 32A is provided.

そして、図２（ｂ）で示すように、上型３２と下型３１との間で光学シート３４を圧延して、基材２１を形成する。   Then, as shown in FIG. 2B, the optical sheet 34 is rolled between the upper mold 32 and the lower mold 31 to form the base material 21.

ここで、下型３１のドーム状の窪み３１Ａと上型３２のドーム状の凸部３２Ｂで基材２１のドーム部２１Ａを形成すると共に、上型３２の円形孔３２Ａにより突出した頭頂部２１Ｄが形成され、下型３１の凹凸部３１Ｂにより発光部２２が形成される。   Here, the dome portion 21A of the base 21 is formed by the dome-shaped recess 31A of the lower die 31 and the dome-shaped convex portion 32B of the upper die 32, and the top portion 21D protruding from the circular hole 32A of the upper die 32 is formed. The light emitting part 22 is formed by the uneven part 31 </ b> B of the lower mold 31.

なお、発光部２２を形成する際に合成樹脂を印刷する手順が不要となり、効率的に可動接点体２５を製造することが可能となっている。   In addition, when forming the light emission part 22, the procedure which prints a synthetic resin becomes unnecessary and it becomes possible to manufacture the movable contact body 25 efficiently.

また、図３のスイッチの断面図において、図３（ａ）に示す６はポリエチレンテレフタレートやポリイミド等のフィルム状、または紙フェノールやガラス入りエポキシ等の板状の配線基板で、上下面には銅等によって複数の配線パターン（図示せず）が形成されると共に、上面には銅やカーボン等によって、略半円形状の固定接点３５Ａと、これと対向した略半円形状の固定接点３５Ｂから形成された、複数の固定接点対３５が設けられている。   Further, in the cross-sectional view of the switch of FIG. 3, 6 shown in FIG. 3 (a) is a film-like wiring board such as polyethylene terephthalate or polyimide, or a plate-like wiring board such as paper phenol or glass-filled epoxy, and the upper and lower surfaces are copper A plurality of wiring patterns (not shown) are formed by, for example, a substantially semicircular fixed contact 35A and a substantially semicircular fixed contact 35B opposed to the upper surface by copper, carbon, or the like. A plurality of fixed contact pairs 35 are provided.

そして、この配線基板６上面に可動接点体２５がセパレータ２４を剥がして載置され、電極部２３は頭頂部２１Ｄの下面の位置で、固定接点３５Ａおよび固定接点３５Ｂと所定の間隙を空けて対向される。   The movable contact body 25 is placed on the upper surface of the wiring board 6 with the separator 24 peeled off, and the electrode portion 23 is opposed to the fixed contact 35A and the fixed contact 35B with a predetermined gap at a position on the lower surface of the top 21D. Is done.

また、８は発光ダイオード等の発光素子で、複数の発光素子８が基材２１側方の配線基板６上面に実装され、基材２１の右端面に発光面を向けて配置されている。   Reference numeral 8 denotes a light-emitting element such as a light-emitting diode. A plurality of light-emitting elements 8 are mounted on the upper surface of the wiring substrate 6 on the side of the base material 21 and are arranged with the light-emitting surface facing the right end surface of the base material 21.

さらに、図３（ａ）において９は操作手段の一例として示す光透過性でフィルム状の表示シートで、下面に印刷等によって形成された遮光部９Ａの所定箇所が、文字や記号等の形状にくり抜かれて複数の表示部９Ｂが形成され、基材２１の頭頂部２１Ｄ上方に貼付されて、スイッチが構成されている。   Further, in FIG. 3 (a), 9 is a light transmissive film-like display sheet as an example of the operation means, and the predetermined portion of the light shielding portion 9A formed by printing or the like on the lower surface has a shape such as a character or a symbol. A plurality of display portions 9B are formed by being cut out, and are pasted on the top 21D of the base material 21 to constitute a switch.

そして、このように構成されたスイッチが、電子機器の操作面に装着されると共に、複数の固定接点３５Ａや固定接点３５Ｂ、複数の発光素子８が配線パターン等を介して、機器の電子回路（図示せず）に接続される。   The switch configured as described above is mounted on the operation surface of the electronic device, and the plurality of fixed contacts 35A, the fixed contacts 35B, and the plurality of light emitting elements 8 are connected to the electronic circuit ( (Not shown).

以上の構成において、表示シート９を下方へ押圧操作すると、表示シート９の下面が基材２１の頭頂部２１Ｄ上面に直接あるいは発光部２２を介して接し、さらに押圧すると頭頂部２１Ｄが下方に沈み、外縁部２１Ｃが変形し始める。   In the above configuration, when the display sheet 9 is pressed downward, the lower surface of the display sheet 9 comes into contact with the top surface 21D of the base material 21 directly or via the light emitting portion 22, and when pressed further, the top portion 21D sinks downward. The outer edge portion 21C starts to deform.

そして所定の押圧力が加わると、図３（ｂ）に示すように、ドーム部２１Ａの外縁部２１Ｃがクリック感を伴って下方へ弾性反転し、電極部２３が頭頂部２１Ｄ下面で固定接点３５Ａと固定接点３５Ｂに接触するため、固定接点３５Ａと固定接点３５Ｂが、電極部２３を介して電気的に接続された状態となる。   When a predetermined pressing force is applied, as shown in FIG. 3 (b), the outer edge portion 21C of the dome portion 21A is elastically reversed downward with a click feeling, and the electrode portion 23 is fixed to the fixed contact 35A on the lower surface of the top portion 21D. Therefore, the fixed contact 35 </ b> A and the fixed contact 35 </ b> B are electrically connected via the electrode part 23.

また、表示シート９への押圧力を解除すると、弾性復帰力によって外縁部２１Ｃが上方へ弾性反転し、電極部２３が固定接点３５Ａおよび３５Ｂから離れて、固定接点３５Ａと固定接点３５Ｂが電気的に切断された状態となる。   Further, when the pressing force to the display sheet 9 is released, the outer edge portion 21C is elastically reversed upward by the elastic restoring force, the electrode portion 23 is separated from the fixed contacts 35A and 35B, and the fixed contact 35A and the fixed contact 35B are electrically connected. It will be in a disconnected state.

つまり、ドーム部２１Ａの頭頂部２１Ｄの変形が抑制され、外縁部２１Ｃで弾性反転することにより、押圧操作時に快適なクリック感が生まれるため、導電塗料をドーム部２１Ａの内壁全面および外縁部２１Ｃの外側周辺に塗布しただけで、導電金属薄板製の可動接点を必要とせず、効率的に製造が可能なスイッチを得ることができるようになっている。   That is, the deformation of the top portion 21D of the dome portion 21A is suppressed, and a comfortable click feeling is generated during the pressing operation by elastically reversing the outer edge portion 21C. A switch that can be manufactured efficiently can be obtained without applying a movable contact made of a thin conductive metal plate simply by coating the outer periphery.

なお、このような固定接点対３５の電気的接離に応じて、機器の各機能の切換えが行われると共に、機器の電子回路から発光素子８に電源が供給されると、複数の発光素子８が発光し、この光が右端面から基材２１内に入射して反射しながら左方へ進む。   Note that each function of the device is switched in accordance with the electrical contact / separation of the fixed contact pair 35 as described above, and when power is supplied from the electronic circuit of the device to the light emitting device 8, the plurality of light emitting devices 8. Is emitted, and this light enters the substrate 21 from the right end face and travels to the left while being reflected.

また、この光が基材２１上面の複数の発光部２２で拡散され反射して、表示部９Ｂを下方から照光し、複数の表示部９Ｂが照光されることによって、周囲が暗い場合でも、表示部９Ｂの文字や記号等の表示が識別でき、操作を容易に行うことが可能なようになっている。   Further, the light is diffused and reflected by the plurality of light emitting units 22 on the upper surface of the base material 21 to illuminate the display unit 9B from below, and the plurality of display units 9B are illuminated. The display of characters, symbols, etc. in the section 9B can be identified, and the operation can be easily performed.

このように本実施の形態によれば、基材２１をドーム部２１Ａの外縁部２１Ｃより頭頂部２１Ｄで厚く形成して可動接点体を構成したものであり、外縁部２１Ｃより頭頂部２１Ｄのほうが基材２１の変形が小さいことで良好なクリック感を作り出せるため、基材２１の下方に別途金属薄板製などの可動接点を設ける必要が無いため、効率的に製造が可能な可動接点体を得ることができるものである。   As described above, according to the present embodiment, the base 21 is formed thicker at the top 21D than the outer edge 21C of the dome 21A to constitute the movable contact body, and the top 21D is more than the outer 21C. Since a good click feeling can be created because the deformation of the base material 21 is small, there is no need to separately provide a movable contact made of a thin metal plate or the like below the base material 21, thereby obtaining a movable contact body that can be manufactured efficiently. It is something that can be done.

なお、以上の説明では、操作手段として表示シート９を例にとり説明したが、これに限定されるものではなく、基材２１のドーム部２１Ａを押圧できる構造であれば、本発明の実施は可能である。   In the above description, the display sheet 9 has been described as an example of the operation means. However, the present invention is not limited to this, and the present invention can be implemented as long as the dome portion 21A of the base material 21 can be pressed. It is.

また、発光部２２は下型３１の凹凸部３１Ｂに光学シート３４が押圧され形成されるものとして説明したが、ドーム部２１Ａの上面や、図２の断面図の光学シート３４と導電塗料３３の間で光透過性の合成樹脂あるいは白色等のインキを印刷する構成としても良い。   In addition, the light emitting unit 22 has been described as being formed by pressing the optical sheet 34 against the concavo-convex part 31B of the lower mold 31, but the upper surface of the dome part 21A and the optical sheet 34 and the conductive paint 33 in the sectional view of FIG. It is good also as a structure which prints a light-transmitting synthetic resin or white ink.
