Description
本発明は、電池を電池保持部材に保持させて機器の筐体へ挿入する電池収納構造、詳しくは電池の一方の面に配置された電極面から回路基板へ電力を取り出す電極端子の構造に関する。また、本発明は、耳に装着して使用される耳装着装置に関する。 The present invention relates to a battery housing structure in which a battery is held by a battery holding member and inserted into a housing of a device, and more particularly to a structure of an electrode terminal for taking out electric power from a surface of an electrode disposed on one surface of a battery to a circuit board. The present invention also relates to an ear wearing device used by being worn on the ear.
電池又は二次電池から電力供給を受ける機器は、電池本体を電池保持部材に保持させて筐体へ挿入する電池収納構造を有する場合がある（特許文献１、２）。電池収納構造は、電池本体の表面に配置されたプラスとマイナスの電極にそれぞれ電極端子を接触させて回路基板へ電力を取り出している（特許文献２）。 A device that receives power supply from a battery or a secondary battery may have a battery housing structure in which a battery main body is held by a battery holding member and inserted into a casing (Patent Documents 1 and 2). In the battery housing structure, the electrode terminals are brought into contact with the positive and negative electrodes arranged on the surface of the battery main body, respectively, and electric power is taken out to the circuit board (Patent Document 2).
特許文献２の電池収納構造は、電池保持部材に保持したボタン電池の周側面のプラス電極に対してはコイルスプリング状の電極端子をほぼ垂直に突き当てて接触させている。一方、プラス電極の内側に配置された上面のマイナス電極に対しては、ばね性を有する薄板をＵ字型に折り返した電極端子をほぼ平行に摩擦して接触させている。薄板をＶ字に折り返して発生させたばね力が、ボタン電池のマイナス電極に電極端子の平坦な電極面を押し当てて接触させている。また、特許文献２には、耳に装着して使用される耳装着装置が示される。図１に示すように、耳装着装置は、耳の孔の入口に保持される頭部４と反対側にクリップ３を設け、筐体４とクリップ３との間に耳を挟み込むことで耳に装着されている場合がある。そして、図２に示すように、回路基板１３の基板面を横断する方向に対向する胴部２の側面に一対のスイッチ（２３、２４）が設けられている場合がある。 In the battery housing structure of Patent Document 2, a coil spring-like electrode terminal is brought into contact with and substantially in contact with a positive electrode on the peripheral side surface of a button battery held by a battery holding member. On the other hand, an electrode terminal obtained by folding a thin plate having a spring property into a U shape is brought into contact with the negative electrode on the upper surface arranged inside the positive electrode by friction in substantially parallel. The spring force generated by folding the thin plate into a V shape presses the flat electrode surface of the electrode terminal against the negative electrode of the button battery to bring it into contact. Patent Document 2 discloses an ear mounting device that is used by being mounted on an ear. As shown in FIG. 1, the ear wearing device is provided with a clip 3 on the side opposite to the head 4 held at the entrance of the ear hole, and the ear is sandwiched between the housing 4 and the clip 3 so that the ear can be inserted into the ear. May be installed. As shown in FIG. 2, a pair of switches (23, 24) may be provided on the side surface of the body portion 2 facing in the direction crossing the substrate surface of the circuit board 13.
引用文献２に示されるように、電池の交換に伴って電池の電極面をほぼ平行に摩擦する電極端子を有する電池収納構造は、長年の使用によって酸化や油分付着やごみ付着が進んだ状態で電池交換を行うと電極端子が接触不良を引き起こす場合がある。 As shown in the cited document 2, the battery housing structure having the electrode terminal that rubs the electrode surface of the battery almost in parallel with the replacement of the battery is in a state in which oxidation, oil adhesion, and dust adhesion have progressed over the years. When the battery is replaced, the electrode terminal may cause poor contact.
本発明は、長年の使用によって酸化や油分付着やごみ付着が進んだ状態で電池交換が行われても接触不良を引き起こし難い電池収納構造、及びリズム発生装置を提供することを目的としている。また、別の本発明は、回路基板の基板面を横断する方向に対向する胴部の側面に一対のスイッチが設けられている場合に好適なスイッチ構造を有する耳装着装置を提供することを目的としている。 An object of the present invention is to provide a battery housing structure and a rhythm generator that are unlikely to cause poor contact even when the battery is replaced in a state where oxidation, oil adhesion, and dust adhesion have progressed over many years. Another object of the present invention is to provide an ear wearing device having a switch structure suitable when a pair of switches are provided on the side surfaces of the body portion facing in the direction transverse to the substrate surface of the circuit board. It is said.
本発明の電池収納構造は、筐体と、一方の面に電極面を有する電池を保持して前記一方の面に沿って移動して前記筐体へ収納される電池保持部材と、前記電池の電力で作動する回路を有して前記筐体に付設された回路基板と、前記回路基板に一端側が固定され、前記筐体に収納された前記電池保持部材に保持された前記電池の前記電極面に他端側が当接する端子部材と、を備えるものである。そして、前記端子部材は、前記一端側を起点として前記一方の面に沿った所定方向から当該所定方向の反対方向へ折り返した後に前記他端側がばね力を伴って前記電極面に曲面で当接するように曲線断面の金属弾性線材を曲げて形成される。また、別の本発明の耳装着装置は、耳の孔の入口に保持される頭部を有し、前記頭部と反対側にクリップが設けられ、前記クリップとの間に耳を挟み込むことにより耳面上に保持される筐体と、前記筐体に収容された回路基板と、前記回路基板に固定して前記回路基板の基板面を横断するように配置され、当該横断する方向の両端がスイッチの電極として機能する共通電極と、前記回路基板に固定して前記両端の一方に対して接離可能に配置された第１のスイッチ電極と、前記回路基板に固定して前記両端の他方に対して接離可能に配置された第２のスイッチ電極と、を備えるものである。 The battery storage structure of the present invention includes a housing, a battery holding member that holds a battery having an electrode surface on one surface, moves along the one surface, and is stored in the housing, A circuit board attached to the housing having a circuit that operates with electric power, and the electrode surface of the battery that is fixed to the circuit board and is held by the battery holding member that is housed in the housing And a terminal member with which the other end abuts. Then, after the terminal member is folded back from a predetermined direction along the one surface from the one end side to a direction opposite to the predetermined direction, the other end side comes into contact with the electrode surface with a curved surface with a spring force. In this way, it is formed by bending a metal elastic wire having a curved cross section. Further, another ear mounting device of the present invention has a head portion held at the entrance of the ear hole, a clip is provided on the opposite side of the head portion, and the ear is sandwiched between the clip. A housing held on the ear surface, a circuit board housed in the housing, and arranged to cross the circuit board surface fixed to the circuit board, and both ends in the transverse direction are A common electrode that functions as a switch electrode, a first switch electrode that is fixed to the circuit board and is detachable from one of the ends, and is fixed to the circuit board and connected to the other of the ends. And a second switch electrode disposed so as to be able to contact and separate.
本発明の電池収納構造は、電池保持部材が移動して端子部材の他端側が電池の電極面に摺擦する際に他端側が曲面で電極面に接触するため、弾性変形した弾性金属線材のばね力が小さくても、接触部に比較的大きな圧力が発生する。そのため、局所的に大きな加圧力で電極面と他端部とが密着して電気的な接触が良好に確保される。 In the battery housing structure of the present invention, when the battery holding member moves and the other end of the terminal member slides on the electrode surface of the battery, the other end contacts the electrode surface with a curved surface. Even if the spring force is small, a relatively large pressure is generated at the contact portion. Therefore, the electrode surface and the other end are in close contact with each other with a large applied pressure, and electrical contact is ensured satisfactorily.
また、端子部材の他端側は、電池が収納されると電池未収納時の位置から変位し、その変位に相当する弾性力が発生して、他端側と電極面との接触圧力を発生して電気的接触抵抗を減少させる。このため、電池未収納時と電池収納時とにおける端子部材の他端側の位置が同じ位置であり続ければ、電池の電極面に対する接触圧力は一定に再現されて、電気的接触抵抗は問題となりにくい。そして、本発明では、「一端側を起点として所定方向から当該所定方向の反対方向へ折り返した後に他端側がばね力を伴って電極面に当接するように金属弾性線材を曲げて形成している」ので、弾性的な形状回復力が薄板材料を用いて同一の形状に曲げて成形したものよりも大きい。 Further, the other end side of the terminal member is displaced from the position when the battery is not accommodated when the battery is accommodated, and an elastic force corresponding to the displacement is generated to generate a contact pressure between the other end side and the electrode surface. To reduce the electrical contact resistance. For this reason, if the position of the other end side of the terminal member when the battery is not stored and when the battery is stored continues to be the same position, the contact pressure with respect to the electrode surface of the battery is reproduced uniformly, and the electrical contact resistance becomes a problem. Hateful. In the present invention, the metal elastic wire is bent so that the other end abuts against the electrode surface with a spring force after being folded back from a predetermined direction to a direction opposite to the predetermined direction starting from one end. Therefore, the elastic shape recovery force is larger than that formed by bending into the same shape using a thin plate material.
したがって、長年の使用によって酸化や油分付着やごみ付着が進んだ状態で電池交換が行われても接触不良を引き起こし難い電池収納構造、及びリズム発生装置を提供できる。また、別の本発明の耳装着装置によれば、回路基板の基板面を横断する方向に対向する胴部の側面に一対のスイッチが設けられている場合に好適なスイッチ構造を有する耳装着装置を提供することができる。 Accordingly, it is possible to provide a battery housing structure and a rhythm generator that are unlikely to cause poor contact even if the battery is replaced in a state where oxidation, oil adhesion, and dust adhesion have progressed over many years. According to another ear mounting device of the present invention, the ear mounting device having a switch structure suitable when a pair of switches are provided on the side surfaces of the body portion facing in the direction crossing the substrate surface of the circuit board. Can be provided.

It is possible to switch the volume of the rhythm sound in two stages by sliding the volume switch 22.
リズム発生装置１は、スタートストップスイッチ２１を長押しすると、液晶表示ユニット２５に現在設定されているリズムの毎分拍数が表示される。液晶表示ユニット２５にリズムの毎分拍数が表示された状態でリズム設定スイッチ２４を押すと、１回押すごとに表示された毎分拍数が１刻みで増加する。また、リズム設定スイッチ２３を押すと、１回押すごとに表示された毎分拍数が１刻みで減少する。このようにして、リズム発生装置１に所望の毎分拍数を設定する。 When the start / stop switch 21 is pressed and held for a long time, the rhythm generator 1 displays the number of beats per minute of the currently set rhythm on the liquid crystal display unit 25. When the rhythm setting switch 24 is pressed in a state where the rhythm beats per minute are displayed on the liquid crystal display unit 25, the beat beats displayed per minute increases every time the rhythm setting switch 24 is pressed. When the rhythm setting switch 23 is pressed, the number of beats displayed per minute decreases every time the rhythm setting switch 23 is pressed. In this way, a desired number of beats per minute is set in the rhythm generator 1.

When the rhythm setting switch 23 is pressed, the number of beats displayed every time the rhythm setting switch 23 is pressed changes in the order of six beats, five beats, three beats, two beats, and one beat. A microcomputer element 26 shown in FIG. 2 as a microcomputer circuit generates a rhythm signal having a variable number of beats per minute. The switch electrodes 23 b and 24 b are used for setting the number of beats per minute for the microcomputer element 26.

The battery holder 14 can be pulled out from the head 4 by rotating the battery holder 14 outward about the pin 12p. When replacing the button battery 15 with a new one, the battery holder 14 is pulled out of the head 4 and the button battery 15 is taken out and replaced with a new one, and the battery holder 14 is pushed back into the head 4.
図３に示すように、電池ホルダ１４に収容されたボタン電池１５は、電池ホルダ１４の回動に伴って矢印Ａ方向に移動して電極端子３０、４０に接触する。図４に示すように、電池ホルダ１４が頭部４に収納された状態では、電極端子（V−接片）３０は、ボタン電池１５の上面に配置されたマイナス電極１５ａに接触する。電極端子（Ｖｄｄ接片）４０は、ボタン電池１５の周面に配置されたプラス電極１５ｂに当接する。 As shown in FIG. 3, the button battery 15 accommodated in the battery holder 14 moves in the direction of arrow A as the battery holder 14 rotates and contacts the electrode terminals 30 and 40. As shown in FIG. 4, in a state where the battery holder 14 is housed in the head 4, the electrode terminal (V-contact piece) 30 contacts the negative electrode 15 a disposed on the upper surface of the button battery 15. The electrode terminal (Vdd contact piece) 40 abuts on the plus electrode 15 b disposed on the peripheral surface of the button battery 15.
電極端子４０は、電池を側方から付き当てれば良いため、単純な形状でコイルばねを導入できる。コイルばねは、ボタン電池１５に当接する作用点の広範な変位に対して弾性領域を確保でき（小さな荷重変化に対して大きな変位量が得られる）、降伏して塑性変形することがない。このような利点を電極端子３０にも応用することが考えられるが、電極端子３０は、ボタン電池１５のマイナス電極１５ａを摺擦してスライドするため、単純な形状では実現できない。ボタン電池１５の挿入過程でスムーズに電極端子３０が乗り上げるためには、１）緩やかな傾斜を有した斜め部３５が必要である。また、乗り上げた以降は、２）接触点として曲線部３６が必要となる。また、電池を出す時のひっかかりを防止するために、３）逆スロープを有した先端部３７が必要となる。そして、４）先端部３７、曲線部３６、斜め部３５をコイル部３２に繋げるために逆行部３３、折り返し部３４が必要となる。このようにして電極端子３０の複雑な曲げ形状が誕生した次第である。 Since the electrode terminal 40 is only required to contact the battery from the side, a coil spring can be introduced with a simple shape. The coil spring can secure an elastic region with respect to a wide range of displacement of the point of contact that contacts the button cell 15 (a large amount of displacement can be obtained with respect to a small load change), and does not yield and plastically deform. Although it is conceivable to apply such advantages to the electrode terminal 30, the electrode terminal 30 cannot be realized with a simple shape because it slides and slides on the negative electrode 15a of the button battery 15. In order for the electrode terminal 30 to ride smoothly during the process of inserting the button battery 15, 1) an inclined portion 35 having a gentle inclination is required. Further, after riding, 2) the curved portion 36 is required as a contact point. Moreover, in order to prevent catching when taking out a battery, 3) the front-end | tip part 37 with a reverse slope is needed. 4) In order to connect the tip portion 37, the curved portion 36, and the oblique portion 35 to the coil portion 32, the retrograde portion 33 and the turn-back portion 34 are required. In this way, a complicated bending shape of the electrode terminal 30 is born.
端子部材の一例である電極端子３０は、一端側が回路基板１３に固定され、ボタン電池１５を保持した電池ホルダ１４が頭部４に収納された状態で他端側がマイナス電極１５ａに当接する。電極端子３０は、曲線断面の金属弾性線材を曲げて形成される。 An electrode terminal 30, which is an example of a terminal member, has one end fixed to the circuit board 13, and the other end contacts the negative electrode 15 a while the battery holder 14 holding the button battery 15 is stored in the head 4. The electrode terminal 30 is formed by bending a metal elastic wire having a curved cross section.
コイル部３２は、回路基板１３に固定された一端側に連続してコイル状に形成される。コイル部３２は、曲線部３６にマイナス電極１５ａへ向かうばね力を付与するため、コイル部３２をねじり変形させるばね力と、曲線部３６の昇降ストロークが追加される。コイル部３２は、回路基板１３に固定された位置よりも逆行部３３側に配置されて回路基板１３面に当接して応力分担している。このため、回路基板１３に固定された根元位置に応力集中が発生せず、根本部分が曲がって永久変形することがない。 The coil portion 32 is continuously formed in a coil shape on one end side fixed to the circuit board 13. Since the coil portion 32 imparts a spring force toward the minus electrode 15 a to the curved portion 36, a spring force that twists and deforms the coil portion 32 and a lifting stroke of the curved portion 36 are added. The coil part 32 is disposed on the retrograde part 33 side from the position fixed to the circuit board 13 and abuts on the surface of the circuit board 13 to share the stress. For this reason, stress concentration does not occur at the root position fixed to the circuit board 13, and the root portion is not bent and permanently deformed.
逆行部３３は、コイル部３２に連続して形成されて電池ホルダ１４が頭部４へ収納される方向の反対方向へ回路基板１３面に沿って配置される。逆行部３３の長さを調整することで、回路基板１３の任意の位置の上空で曲線部３６をマイナス電極１５ａに当接できる。逆行部３３は、その全長にわたって回路基板１３面から離間している。このため、コイル部３２のねじり変形が逆行部３３を昇降させて、曲線部３６のマイナス電極１５ａに対する加圧力を小さく保って曲線部３６の昇降ストロークを大きく確保できる。 The retrograde portion 33 is formed along the surface of the circuit board 13 in a direction opposite to the direction in which the battery holder 14 is housed in the head 4 by being formed continuously with the coil portion 32. By adjusting the length of the retrograde portion 33, the curved portion 36 can be brought into contact with the negative electrode 15 a in an arbitrary position on the circuit board 13. The retrograde portion 33 is spaced from the surface of the circuit board 13 over its entire length. For this reason, the torsional deformation of the coil part 32 raises and lowers the retrograde part 33, and the pressurizing force of the curved part 36 against the negative electrode 15 a can be kept small, and a large raising and lowering stroke of the curved part 36 can be secured.
折り返し部３４は、逆行部３３から電池ホルダ１４が頭部４へ収納される方向へ折り返すように形成されて斜め部３５に連続する。このため、逆行部３３と斜め部３５との交差角を変化させるばね力と、曲線部３６の昇降ストロークが追加される。斜め部３５は、電池ホルダ１４が頭部４へ収納される過程で前記一方の面の縁に斜めに当接する。斜め部３５は、電池ホルダ１４が頭部４へ収納される過程でボタン電池１５の端部に斜めに当接して、弾性変形を伴って乗り上げるため、電池ホルダ１４の移動に伴う曲線部３６のマイナス電極１５ａへの乗り上げが円滑で不必要な摩擦を生じない。 The folded portion 34 is formed so as to be folded in the direction in which the battery holder 14 is housed in the head 4 from the retrograde portion 33 and continues to the oblique portion 35. For this reason, the spring force which changes the crossing angle of the retrograde part 33 and the diagonal part 35, and the raising / lowering stroke of the curved part 36 are added. The inclined portion 35 is in contact with the edge of the one surface obliquely in the process of storing the battery holder 14 in the head 4. The slanted portion 35 obliquely abuts against the end of the button battery 15 in the process in which the battery holder 14 is housed in the head 4 and rides on with elastic deformation. The ride on the negative electrode 15a is smooth and does not cause unnecessary friction.
曲線部３６は、斜め部３５に連続して形成されて電池ホルダ１４が頭部４へ収納された状態でマイナス電極１５ａに当接する。斜め部３５が変形してマイナス電極１５ａに対する姿勢、傾きが変化しても、曲面がマイナス電極１５ａに接触するので不必要な摩擦を生じない。 The curved portion 36 is formed continuously with the oblique portion 35 and comes into contact with the negative electrode 15 a in a state where the battery holder 14 is stored in the head 4. Even if the inclined portion 35 is deformed and the posture and inclination with respect to the minus electrode 15a are changed, unnecessary friction is not generated because the curved surface is in contact with the minus electrode 15a.
コイル部３２の曲率半径０．８５ｍｍよりも折り返し部３４の曲率半径１ｍｍが大きい。このため、逆行部３３と斜め部３５との間隔が柔軟に変化して、曲線部３６に電極１５ａを傷つけるような過剰な圧力を生じない。金属弾性線材は、円形断面で直径０．３ｍｍである。０．７ｍｍ以下であるため、小さな加圧力でも大きな面圧力を発生する。小さな面圧力でも円形断面と基板面の当接領域から外側へ異物を押し出す力が大きい。 The curvature radius 1 mm of the folded portion 34 is larger than the curvature radius 0.85 mm of the coil portion 32. For this reason, the space | interval of the retrograde part 33 and the diagonal part 35 changes flexibly, and the excessive pressure which damages the electrode 15a to the curved part 36 is not produced. The metal elastic wire has a circular cross section and a diameter of 0.3 mm. Since it is 0.7 mm or less, a large surface pressure is generated even with a small applied pressure. Even with a small surface pressure, the force for pushing out foreign matter from the contact area between the circular cross section and the substrate surface is large.
（比較例との対比）
特許文献２の図２には、ボタン電池を電池ホルダに保持して筐体から引き出し可能に構成したリズム発生装置が示される。特許文献２のリズム発生装置において、ボタン電池の上面のマイナス電極に接触する電極端子を比較例として、図３に示す実施例の電極端子３０と比較する。
(Contrast with comparative example)
FIG. 2 of Patent Document 2 shows a rhythm generator configured to hold a button battery in a battery holder so that the button battery can be pulled out from the housing. In the rhythm generator of Patent Document 2, an electrode terminal that contacts the negative electrode on the upper surface of the button battery is compared with the electrode terminal 30 of the embodiment shown in FIG. 3 as a comparative example.
特許文献２のリズム発生装置は、回路基板に一端を固定して起立させた円形断面の金属弾性線材の電極端子をボタン電池の周面のプラス電極に接触させている。一方、回路基板に一端を固定してＵ字型に曲げて成形した金属薄板の電極端子をボタン電池の上面のマイナス電極に接触させている。 In the rhythm generator of Patent Document 2, an electrode terminal of a metal elastic wire having a circular cross section, which is fixed up on one end of a circuit board, is brought into contact with a plus electrode on the peripheral surface of the button battery. On the other hand, an electrode terminal of a thin metal plate formed by bending one end of the circuit board and bending it into a U shape is brought into contact with the negative electrode on the upper surface of the button battery.
実施例の電極端子３０は、曲面をボタン電池のマイナス電極１５ａに接触させるから、比較例のように平面もしくは円筒面をボタン電池のマイナス電極に接触させる場合よりも小さな加圧力で接触部の当接圧力を高めることができる。実施例の電極端子３０では、曲線部３６とマイナス電極１５ａの接触面において接触の中心から周囲へ向かって低くなる圧力分布が形成されるため、接触面の油脂や異物は外へ押し出されて接触を妨げにくい。曲面と平面とが接触する実施例の接触面には、比較例における平板同士の接触面よりも浸透圧によって水や油脂が侵入しにくい。 Since the electrode terminal 30 of the embodiment has a curved surface in contact with the negative electrode 15a of the button battery, the contact portion of the contact portion can be applied with a smaller pressure than when a flat surface or a cylindrical surface is in contact with the negative electrode of the button battery as in the comparative example. The contact pressure can be increased. In the electrode terminal 30 of the embodiment, since a pressure distribution that decreases from the center of contact toward the periphery is formed on the contact surface between the curved portion 36 and the negative electrode 15a, the oil and foreign matter on the contact surface are pushed out and contacted. It is hard to disturb. Water and fats and oils are less likely to enter the contact surface of the embodiment where the curved surface and the flat surface are in contact with each other by the osmotic pressure than the contact surface between the flat plates in the comparative example.
実施例の電極端子３０は、比較例の電極端子よりもばね定数が小さく、慣性質量も小さいため、振動や衝撃を受けた際に接触が外れにくい。実施例の電極端子３０は、比較例の電極端子よりもばねのストロークが大きいため、塑性変形しにくい。実施例の電極端子３０は、円形断面なので体積／表面積が大きく耐久性がある。 Since the electrode terminal 30 of the example has a smaller spring constant and a smaller inertial mass than the electrode terminal of the comparative example, the contact is unlikely to come off when subjected to vibration or impact. Since the electrode terminal 30 of the example has a larger spring stroke than the electrode terminal of the comparative example, it is difficult to be plastically deformed. Since the electrode terminal 30 of the embodiment has a circular cross section, the volume / surface area is large and the electrode terminal 30 is durable.
したがって、実施例のリズム発生装置１は、特許文献２のリズム発生装置よりもボタン電池の上面のマイナス電極と電極端子の接触が確実である。 Therefore, the rhythm generator 1 of the embodiment is more reliable in contact with the negative electrode on the upper surface of the button battery and the electrode terminal than the rhythm generator of Patent Document 2.
（実施例の効果）
携帯用電子機器の電池及び電極端子は、汗、外気、湿気、体温、塩分等に晒されて接触不良を引き起こし易い。電極がさびていたり、電極に油がついていたりする電池は、そのような携帯用電子機器で使用すると、接触不良で電力を取り出せない場合がある。特に、 高湿度、大気汚染の環境で製造され、保管された電池を使用すると接触不良を引き起こし易い。
(Effect of Example)
Batteries and electrode terminals of portable electronic devices are easily exposed to sweat, outside air, moisture, body temperature, salinity, etc., and cause poor contact. Batteries with rusted electrodes or oiled electrodes may not be able to extract power due to poor contact when used in such portable electronic devices. In particular, the use of batteries manufactured and stored in high humidity and air polluted environments tends to cause poor contact.
実施例のリズム発生装置は、このような過酷な使用環境で品質の良くないボタン電池の交換を繰り返した場合でも、電極端子３０、４０とボタン電池１５との接触圧が高く維持されて接触不良を引き起こしにくい。 The rhythm generator according to the embodiment maintains a high contact pressure between the electrode terminals 30 and 40 and the button battery 15 even when the button battery having poor quality is repeatedly replaced in such a harsh use environment. It is hard to cause.
電極面に電極端子を押し付ける形式の電池収納構造では、電極端子に加圧方向の大きな力が作用すると、電極端子が塑性変形してばね力が失われ、電極面に対する電極端子の接触圧が低下することがある。この場合、隙間に水分や油膜が侵入して接触不良を引き起こす場合がある。 In a battery housing structure in which the electrode terminal is pressed against the electrode surface, if a large force in the pressurizing direction acts on the electrode terminal, the electrode terminal is plastically deformed and the spring force is lost, and the contact pressure of the electrode terminal against the electrode surface decreases. There are things to do. In this case, moisture or an oil film may enter the gap and cause contact failure.
実施例のリズム発生装置は、ボタン電池１５のマイナス電極１５ａに押されて斜め部３５を後退させるように弾性変形した弾性金属線材のばね力が曲線部３６の曲線断面をマイナス電極１５ａの電極面に押し当てる。そのため、局所的に大きな加圧力でマイナス電極１５ａと曲線部３６とが密着して電気的な接触を保つことができる。また、曲面と平面とを接触させるため、電極端子３０の摺擦に伴って界面に汚れや油脂を巻き込みにくく、高圧の接触部には水や油脂が侵入しにくい。 In the rhythm generator of the embodiment, the spring force of the elastic metal wire elastically deformed so as to retreat the oblique portion 35 by being pushed by the negative electrode 15a of the button battery 15 shows the curved section of the curved portion 36 as the electrode surface of the negative electrode 15a. Press against. Therefore, the minus electrode 15a and the curved portion 36 can be in close contact with each other with a large applied pressure, and electrical contact can be maintained. In addition, since the curved surface and the flat surface are brought into contact with each other, dirt and oil and fat are less likely to be caught in the interface as the electrode terminal 30 is rubbed, and water and oil and fat are less likely to enter the high-pressure contact portion.
また、電池ホルダ１４の出し入れ、ボタン電池１５の交換を繰り返しても塑性変形が発生せず、先端部３７が同じ位置に復原する。このため、接触面の摩擦力が増大して電極端子３０の塑性変形に至ったり、接触面の加圧力が減少して接触不良に至ったりしにくい。 Further, even when the battery holder 14 is taken in and out and the button battery 15 is exchanged repeatedly, plastic deformation does not occur, and the distal end portion 37 is restored to the same position. For this reason, it is difficult to increase the frictional force of the contact surface and lead to plastic deformation of the electrode terminal 30 or to reduce the contact surface pressing force to cause poor contact.
したがって、接触圧が高く維持されて接触不良を引き起こしにくい電池収納構造、及びリズム発生装置を提供できる。 Therefore, it is possible to provide a battery housing structure and a rhythm generating device that maintain a high contact pressure and hardly cause poor contact.
＜その他の実施例＞
本発明は、電池の電極に曲線断面の金属弾性線材を曲げてばね性を持たせて当接させる限りにおいて、実施形態の構成の一部を別の構成で置き換えた別の実施形態でも実施可能である。
<Other examples>
The present invention can be implemented in another embodiment in which a part of the configuration of the embodiment is replaced with another configuration as long as the metal elastic wire having a curved cross section is bent and brought into contact with the electrode of the battery to have a spring property. It is.
したがって、電池ホルダは、筐体から回動式に引き出す形態に限らず、スライド式に引き出す形態で実施してもよい。電池収納構造は、耳に装着するリズム装置には限らず、電池はボタン電池に限らない。したがって、本発明は、携帯電話に二次電池を収納する実施形態で実施してもよい。 Therefore, the battery holder is not limited to a form that pulls out from the housing in a pivotal manner, but may be implemented in a form that pulls out in a sliding manner. The battery housing structure is not limited to a rhythm device worn on the ear, and the battery is not limited to a button battery. Therefore, the present invention may be implemented in an embodiment in which a secondary battery is stored in a mobile phone.
