Description

【発明の属する技術分野】
この発明は、電磁振動体に関し、特に携帯電話等、体感振動によって着信の合図とする機能を具備する機器に用いる電磁振動体及び電磁振動体を具備した機器に関する。
【０００２】
【従来の技術】
従来、特に携帯電話等の通信機器に装着する電磁振動体は、その振動源として信頼性が要求されるため、給電端子が堅く半田付けされることが多い。また、電磁振動体を弾性的に支持した場合にはリード線を長くして半田付けする構造が多く採用されている。
しかし、近年において電磁振動体を容易に取付けることの必要性が生じ、ボタン電池のような弾性接触式の電気接続構造が採用されるようになってきている。尚、これらの例として、特開平８−３０８１７０号，特開平11-１３６９号等がある。
しかしながら、これらの構造は電磁振動体を機器内にて弾性支持するには適当ではない。何故なら、電磁振動体を弾性接触により弾性的に保持した場合、弾性的に変形する給電端子を片持ち状態にて支持しているため自由端側の振れが多い。従って、機器内に設けた給電ランドに給電端子先端の電気接触部が電気接触して振動することによって、同電気接触部と機器の給電ランドとが過剰に擦れ合って、経時変化と共に電気接触部に接触不良を生じることがある。
また、給電端子を弾性保持するために圧縮可能な弾性押圧体の一部を使い、その押圧力を利用して電気接触部の接触圧力を維持するものがある。例えば特許文献１参照。
ところが、上記したこれらの弾性押圧体は高分子絶縁材料を用いるため、加圧状態で長時間一定な弾性力を維持することが難しく、使用環境によっては短期間で押圧力が低下する可能性を有している。

【００１２】

【００１３】
【発明の実施の形態】
以下、本発明の一実施例を図面に基づいて説明する。
図１及び図３にて示す電磁振動体Ａは、設置する機器として携帯電話に設置した場合を示している。即ち、この電磁振動体Ａは感振動により着信の合図を持ち主に促す機能を具備する。躯体１は携帯電話の裏躯体であり、この躯体１の内面に振動発生機構８を装着してある。
振動発生機構８は小型のコアレスモータからなり、その出力軸８ａに分銅１０を偏芯した状態で嵌装して固定してある。振動発生機構８はケース８ｃを具備し、該ケース８ｃ内に機能部を収納してある。ケース８ｃは圧延鋼板等を用いた筒状態からなり、その前側端から軸受け部８ｂと出力軸８ａとを突出してある。
【００１４】
また、振動発生機構８のケース８ｃの外周には非弾性の合成樹脂から成形した支承体４を止着してある。支承体４は給電端子７等を支承支持する固定部材である（図１）。
支承体４はケース８ｃの外周面に被着する被着部４ｃと、該被着部４ｃの後端に一体成形した後部カバー４ｄと、同被着部４ｃの先端部に一体成形した先端固定部４ｂとからなる。後部カバー４ｄは支承体４の後端に端子固定部４ａと共に一体形成し、ケース８ｃの後端部の開口を覆うように嵌装してある。後部カバー４ｄ部は、その内部にて振動発生機構８となるモータのブラシを支承している。また、支承体４の後部には振動発生機構８の給電端子７の基端側を挿通せしめて固定する端子固定部４ａを有し、この端子固定部４ａと後部カバー４ｄとにより同給電端子７の基端部を支持してある。
【００１５】
一方、支承体４の上部側には先端固定部４ｂを突出形成してあり、該先端固定部４ｂに上記給電端子７の先端部を嵌挿して取り付け固定してある。即ち、給電端子７は上記端子固定部４ａと先端固定部４ｂとにより両持ち状態で支持してある。また、給電端子７は、端子固定部４ａと、先端固定部４ｂとの間で側面視略山形に屈曲した状態で突出し、その中央部に電気接触部７ａを形成してある。
また、上記したように側面視略山形に湾曲させた給電端子の先端部は先端固定部内で固定せずに同端子の変形に応じて嵌挿部分でスライドするように構成してもよい。
【００１６】
図３にて示すように、給電端子７はブラス極，マイナス極の２本一対の線材であり、バネのような弾性と通電性を有する線材を用いて成る。また、給電端子７の中央部には仮想円形の内側にてＳの字を描くように線材を湾曲させて電気接触部７ａを構成してある。また、上記給電端子７の電気接触部７ａは、給電端子７の給電ランド６に対応する部分を同給電ランド６に対向する仮想平面上において上記したようにＳの字状に湾曲させて形成し、これにより取付板２の内側に所定の間隔を置いて設けた平面的な給電ランド６に対して広い範囲で接触するように構成してある。
【００１７】
上記したケース８ｃは、躯体１の内面に対して弾性体５を介して取付けられ、後述する取付板２との間に挟持される。
弾性体５は、良好な弾性力を有する合成樹脂やゴム材から成り、ケース８ｃの前端側と給電端子７や端子固定部４ａ，先端固定部４ｂの露出部位を除いた部分を被覆する形で装着してある（図２）。
一方、ケース８ｃを挟んで躯体１と対向する取付板２には電源回路に連絡する２枚の給電ランド６を平行状に配設してある。取付板２は躯体１と重なり合うもう一つの躯体（図示せず）側に直接的若しくは間接的に取付固定され、その内面における給電端子７に対応する位置には給電ランド６を構成する通電板６'を貼着して固定してある。
【００１８】
上記した如く給電ランド６を設けた取付板２は、図１にて示す接合面ｂまで押圧して接合する（図１）。この状態により、振動発生機構８のケース８ｃは非弾性体である支承体４と弾性体５との間に挟持される。この際の挟持力は圧縮した弾性体５が発生する反発力である。
本実施例において、非弾性体からなる支承体４と取付板２との対向面同士が直接に接触した状態で挟持されるため、給電ランド６とケース８ｃ'との間隙を一定に維持できるので、給電端子７の給電ランド６に対する押圧力、即ち電気接触も一定に保つことができる。
【００１９】
また、振動発生機構８のケース８ｃを挟持した状態では、側面視略山形に形成した両給電端子７の電気接触部７ａの略Ｓ形曲部が弾性変形し、取付板２による押圧により押さえ込まれる。これにより、電気接触部７ａは、各々に対応する給電ランド６に対して平面的且つ広範囲に接触する（図４）。さらに、上記したような挟持状態が維持される状態では、両給電端子７の圧縮量ｘ（ストローク）が一定に維持されるので、電気圧接力も一定に維持することができる。
【００２０】
図５はコイルバネを利用して成る給電端子７０である。この給電端子７０はバネ線材を３〜４周巻回してコイルバネ状に形成し、このコイルの周面を給電ランドと接触する電気接触部７０ａとしている。電気接触部７０ａのコイルの一端と他端とからは真っ直ぐに線材が延出し、端子固定部４ａと先端固定部４ｂに嵌入して支持してある。
この給電端子７０は上記した給電端子７と同様に機能するが、バネ弾性が良好なので給電ランドに対する電気圧接力が安定して継続し、しかも耐久性も高い。
【００２１】
次に本発明の第２実施例を図６に基づいて説明する。
この電磁振動体Ａ２は、上記した電磁振動体Ａと基本構成が共通するが、支承体４の後部カバー４ｄ'にケース８ｃ'のマグネット収納部８ｄを嵌合して支持する支承孔４ｅを開設してある。また、ケース８ｃ'の周囲に被装する弾性体５１は、開口部５２，５３，５４を開設し、振動発生機構８の軸受部８ｂと給電端子ａ、ケース８ｃ'のマグネット後端収納部８ｄが露呈するように構成してある。尚、上記した振動発生機構８は軸受部８ｂによりモータのシャフトを片持ちで支持すると共にモータのブラシを装着している。
【００２２】
また、躯体１の内面には上記弾性体５１をピッタリと嵌入して収納する収納凹部１ａを一体成形してある。この収納凹部１ａに振動発生機構８を収納したケース８ｃ'を嵌装すると、躯体１の収納凹部１ａ内において振動発生機構８のケース８ｃ'が弾性体５１を介して固定される（図６）。
次いで取付板２を弾性体５１により被覆されたケース８ｃ'及び端子固定部４ａと先端固定部４ｂに対して押圧すると、振動発生機構８のケース８ｃ'は上記した如く被装した弾性体５１を介して躯体１と取付板２の間に挟持される。この状態において給電端子７は電気接触部７ａを取付板２の内面に設けた給電ランド６に押圧して押し下げられた状態となる（図４）。
【００２３】
上記したように、躯体１と取付板２の間に装着した電磁振動体Ａ２は、圧縮せしめた弾性体５１により振動発生体８のケース８ｃ'を包むように挟持することで、同弾性体５１が発する弾性的反発力により振動発生体８のケース８ｃ'を安定して保持することができる。また、振動発生機構により発生する振動を、弾性体５１を介することで躯体１と取付板２との双方へ安定的に伝達することができる。
【００２４】
【発明の効果】
本発明は、以上のように構成したものであるから、電磁振動体は弾性体を用いて弾性的に保持するか、非弾性体を用いて堅く保持するかに代わらず、その給電端子と給電ランドとの電気接続を接触により確実な電気接続を継続することができる。
よって、電気接続を接触によって行なう構造を持つ従来の電磁振動体のように、振動による接触不良や衝撃による接触不良の問題を確実に解決することができる。また、高分子弾性体の有する問題、即ち、長期間の使用に伴う弾性力の低下に伴う電気接触部の接触不良もなく、これにより電気接続の構造が持つ信頼性を格段と向上し得る。
尚、本発明にあっては、弾性体によるによる押圧力は必ずしも必要ではない。その結果、部品点数を削減して電磁振動体の実質容積を減少させることも可能になり、組み立て易く且つ信頼性に優れた電池駆動機器、例えば携帯電話等に有効利用することができる。
【００２５】
請求項１の電磁振動体の給電端子は上記非弾性体により両端部を保持して（両持ち状態）バネ機能を具備せしめ、該給電端子の中間部は機器内に設置される給電ランドに対して弾性的に押圧せしめる電気接触部として成し、この電気接触部を機器内に固定した給電ランドに対して一定な力により弾性的に押圧せしめることにより、振動発生機構に対する給電を安定化して信頼性の高い電気接触性を実現することができる。
【００２６】
請求項請２記載の電磁振動体は、振動発生機構の給電端子として、給電端子を構成する通電線材としてバネ線材を用い、給電ランドに電気接触する部分は、線材を仮想平面上において適宜な形状に湾曲せしめて構成したものである。
よって、給電端子湾曲部分の電気接触部は給電ランドに対して接触面積を増大することができ、接触給電の信頼性を高めることができる。
【００２７】
請求項３記載の電磁振動体は、請求項１記載の電磁振動体において、振動発生機構の給電端子は、同給電端子を構成する通電線材してバネ線材を用い、給電ランドに電気接触する部分は、線材を仮想平面上において適宜な形状に湾曲せしめたものであから、上述した請求項１記載の電磁振動体のように給電端子を両持ち状態にて保持することにより弾性を安定化して信頼性の高い電気接触性を得ると共に、請求項２記載の電磁振動体のように、電気接触部を給電ランドに対して広い接触面積を介して接触するとにより接触給電の信頼性を高める効果を奏する。
【００２８】
請求項４記載の電磁振動体は、請求項１又は３記載の電磁振動体において、
上記給電端子の両端部を非弾性材により保持し、その中間部をコイルバネ状に巻回して電気接触部として成るものであるから、給電端子を両持状態で保持することによりコイル部分により良好な弾性変形特性を発揮し、接触給電の信頼性をより高めることができる。
【００２９】
請求項５記載の電磁振動体は、請求項１又は請求項４の何れか１項記載の電磁振動体において、振動発生機構のケースに被装した非弾性体は、機器に直接接触せしめるように成すと共に、上記給電ランドとケースとの間に所定寸法の間隙を形成し、この間隙内に配置される給電端子を機器の給電ランドに対し弾性的に接触するように構成したものであるから、非弾性体が機器の一部に直接当接することで、給電端子とケースとの間に適正な間隙を確保し、これにより給電端子を給電ランドに対して適正な接触圧で接触し、この状態を長期にわたり継続することができる。
また、給電端子の押圧力として高分子絶縁材料の弾性を利用しなくとも給電端子の押圧力を適正に維持できるので、従来のもののような接触不良を生じることもない。
【００３０】
請求項６記載の電磁振動弾性体は、請求項１乃至５の何れか１項記載の電磁振動体において、非弾性体を振動発生機構のブラシを保持するブラシ台と一体に形成して成したものであるから、非弾性体のホルダーとモータのブラシ台の支持部分とを一体化することで部品点数を削減し組み立て性を向上すると共に、絶縁性と給電端子の適正接触圧を維持する効果とを兼備えることができる。
【００３１】
請求項７記載の電磁振動体は、請求項１乃至６の何れか１項記載の電磁振動体において、振動発生機構は、非弾性体と弾性体とにより挟持して機器内に支持して成るものであるから、弾性体による押圧力により振動発生機構のケースと非弾性部材とを機器の給電ランドの周囲に固定した状態で挟持できると共に、振動発生機構による振動を上記した如く弾性体を介在するとで、機器に対して安定的に伝達することができる。
【００３２】
請求項８記載の機器は、請求項１乃至７の何れか１項記載の電磁振動体を具備する機器であるから、上記した請求項１乃至７記載の電磁振動体の有する効果を発揮できる機器となる。

2. Description of the Related Art Conventionally, since an electromagnetic vibrator to be mounted on a communication device such as a mobile phone is required to have high reliability as a vibration source, a power supply terminal is often firmly soldered. Further, when the electromagnetic vibrator is elastically supported, a structure in which the lead wire is lengthened and soldered is often used.
However, in recent years, it has become necessary to easily attach an electromagnetic vibrator, and an elastic contact type electric connection structure such as a button battery has been adopted. Examples of these are disclosed in JP-A-8-308170 and JP-A-11-1369.
However, these structures are not suitable for elastically supporting the electromagnetic vibrator in the device. This is because when the electromagnetic vibrating body is elastically held by elastic contact, the elastically deformed power supply terminal is supported in a cantilevered state, and therefore the free end side tends to vibrate. Therefore, when the electric contact portion at the tip of the power supply terminal makes electrical contact with the power supply land provided in the device and vibrates, the electric contact portion and the power supply land of the device are excessively rubbed with each other, and the electric contact portion is changed with time. May cause poor contact.
Further, there is a device that uses a part of a compressible elastic pressing body to elastically hold a power supply terminal and uses the pressing force to maintain a contact pressure of an electric contact portion. See, for example, Patent Document 1.
However, since these elastic pressing bodies use a polymer insulating material, it is difficult to maintain a constant elastic force in a pressurized state for a long time, and depending on the use environment, the pressing force may decrease in a short period of time. Have.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The electromagnetic vibrating body A shown in FIGS. 1 and 3 shows a case where the electromagnetic vibrating body A is installed in a mobile phone as a device to be installed. That is, the electromagnetic vibrating body A has a function of prompting the owner to give a signal of an incoming call by vibrating. The frame 1 is a back frame of a mobile phone, and a vibration generating mechanism 8 is mounted on the inner surface of the frame 1.
The vibration generating mechanism 8 is composed of a small coreless motor, and a weight 10 is fitted and fixed to the output shaft 8a in an eccentric state. The vibration generating mechanism 8 includes a case 8c, and a functional unit is housed in the case 8c. The case 8c has a cylindrical shape using a rolled steel plate or the like, and has a bearing 8b and an output shaft 8a protruding from the front end thereof.

In addition, a bearing 4 molded from an inelastic synthetic resin is fixed to the outer periphery of the case 8c of the vibration generating mechanism 8. The support 4 is a fixing member that supports the power supply terminal 7 and the like (FIG. 1).
The support body 4 has an attachment portion 4c attached to the outer peripheral surface of the case 8c, a rear cover 4d integrally formed at the rear end of the attachment portion 4c, and a tip fixing integrally formed at the tip end of the attachment portion 4c. 4b. The rear cover 4d is formed integrally with the rear end of the support 4 together with the terminal fixing portion 4a, and is fitted so as to cover the opening at the rear end of the case 8c. The rear cover 4d supports a brush of a motor serving as the vibration generating mechanism 8 inside thereof. Further, at the rear part of the support body 4, there is provided a terminal fixing part 4a for inserting and fixing the base end side of the power supply terminal 7 of the vibration generating mechanism 8, and this terminal fixing part 4a and the rear cover 4d form the same power supply terminal 7. The base end is supported.
[0015]
On the other hand, a distal end fixing portion 4b is formed to protrude from the upper side of the support body 4, and the distal end portion of the power supply terminal 7 is fitted and fixed to the distal end fixing portion 4b. That is, the power supply terminal 7 is supported in a double-supported state by the terminal fixing portion 4a and the tip fixing portion 4b. The power supply terminal 7 projects between the terminal fixing portion 4a and the distal end fixing portion 4b in a state of being bent in a substantially mountain shape in a side view, and has an electric contact portion 7a formed at the center thereof.
