Description

【０００１】
【発明の属する技術分野】
本発明は、電池によって駆動される機器に電池を収容したときに、電池を固定する電池固定具に関する。
【０００２】
【従来の技術】
従来、電池によって駆動される機器では、この機器に電池収容部を設け、この電池収容部内面にスポンジやゴムなどの弾性体を配置し、この弾性体によって電池のがたつきを吸収することが行われていた。或いは、電池収容部内に設けられている電極接点の弾性を利用して、電池収容部内に電池を固定し、がたつきを抑えることが行われていた。
【０００３】
【発明が解決しようとする課題】
一般に、電池の寸法公差は大きい。この公差分を吸収した上で、電池収容部内面の弾性体や電極接点の弾性を利用して、電池収容部内に電池を固定しようとすると、電池が電池収容部内に引っかかり、出し入れがしにくい。電池の出し入れをしやすくすると、電池のがたつきを抑えることができず、電池を固定することができなかった。
【０００４】
本発明は、電池の出し入れがしやすく、かつ電池のがたつきを抑えた電池固定具を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明による電池固定具は、電池収容部を有し、これは、上部に開口部を有し、この開口部から内部に電池が収容される。この電池としては、種々のものを使用することができ、例えば角型電池や円柱状のものを使用することができる。開口部上に非存在の非被蓋状態から、少なくとも前記開口部上に位置して前記開口部を覆う被蓋状態まで、一定の摺動方向に摺動可能に蓋部材が設けられている。非被蓋状態において、舌片が前記摺動方向に沿って斜め上方に前記開口部より突出し、かつ前記蓋部材に当接している。この舌片は、蓋部材の非被蓋状態から被蓋状態への摺動によって開口部側に回転し、被蓋状態において前記電池に押圧される。
【０００６】
この固定具によれば、蓋部材が開口部を被蓋した状態において、蓋部材が舌片を電池に押圧している。従って、電池が電池収容部内においてがたつくことがない。また、蓋部材が開口部を被蓋していない状態では、舌片は、開口部から離れる方向に位置しているので、舌片が電池の出し入れの邪魔になることはなく、電池収容部内に電池を押圧固定するための弾性体等も存在しない。従って、電池の出し入れが速やかに行われる。
【０００７】
前記電池収容部の開口部は、前記電池の長さ寸法にほぼ等しい長さ寸法を有し、互いに対向する長縁部と、前記電池の幅寸法にほぼ等しい長さ寸法を有し互いに対向する短縁部とを、備え、前記蓋部材は、一方の短縁部側から他方の短縁部側に前記開口部の長縁部に沿って前記非被蓋状態から前記被蓋状態に摺動可能に形成され、前記舌片が、前記開口部の一方の短縁部側に形成されている。
【０００９】
このように構成すると、蓋部材を開口部の長縁に沿って摺動させることによって電池収容部を被蓋するときに、蓋部材を摺動させるために蓋部材に加えた力の分力が舌片に加わり、開口部側に舌片を押圧することができる。従って、被蓋作業を行うと同時に舌片による角型電池の押圧を行うことができ、作業性が向上する。
【００１０】
電池として使用する角型電池は、その一端面に寸法の異なる２つの電極を有している。前記電池収容部の短縁部に、前記角型電池の２つの異なる寸法の電極が接続される２つの接点片を形成することができる。これら２つの接点片は、同一形状とすることがある。これら２つの接点片のうち、前記角型電池における小さい寸法の電極が接触するものの両側に、前記角型電池の大きい寸法の電極の寸法よりも小さい間隔をおいて突部が形成されている。
【００１１】
角型電池の２つの電極を電池収容部の２つの接点片にそれぞれ接触させるとき、極性を誤って接続する可能性がある。特に、開口部を介して角型電池を出し入れしているので、この可能性は高い。しかし、角型電池の小さい寸法の電極が接触する接点片の両側に、角型電池の大きい寸法の電極の寸法よりも小さい間隔をおいて突部を形成しているので、角型電池の大きい寸法の電極が、角型電池の小さい寸法の電極用の接点片に誤って接続されることを突部が阻止する。即ち、角型電池の誤接続を防止できる。
【００１２】
舌片は、被蓋状態において電池に当接する側の摩擦係数が反対側の摩擦係数よりも大きく形成されているものとできる。このように構成すると、舌片が電池を強固に固定することができる。従って、電池収容部を移動させても、移動中に電池が、がたつくことがない。
【００１３】
或いは、舌片は、被蓋状態において舌片の前記電池に当接する側に舌片よりも摩擦係数が大きく、弾性を有する当接部材を形成することもできる。
【００１４】
このように構成すると、電池を電池収容部内に強固に固定することができるので、電池収容部を移動させても、移動中に電池ががたつくことがない上に、当接部材が弾力を有するので、電池の寸法公差、特に開口部に向かう方向の寸法公差を吸収し、かつ電池を押しつけるテンションを得ることができる。
【００１７】
【発明の実施の形態】
本発明の１実施の形態による電池固定具は、例えば図１に示すようなワイヤレスマイクロホンに実施されている。無論、他の電気機器にも実施することができる。このワイヤレスマイクロホンは、本体部２と、蓋部材４とを備えている。
【００１８】
本体部２は、概略円筒状に形成され、図示を省略しているが、その前半部分にマイクロホンと、このマイクロホンで集音した音声信号を送信するための送信回路とが、設けられている。本体部２の後半部に電池収容部６が設けられている。電池収容部６は、本体部２の後半部をその長さ方向に沿う中心軸に沿う水平面よりも上部を除去した形状である。電池収容部６は、その上部に開口部を有し、その内部に、例えばＪＩＳ規格、ＩＥＣ規格の６Ｆ２２、６ＬＲ６１タイプの角型電池１２を収容可能に形成されている。
【００１９】
電池収容部６の開口部は、図３に示すように、対向する２つの長縁部８を有し、さらに長縁部８と直交する２つの短縁部１０を有している。長縁部８は、角型電池１２の長縁よりも若干長い長さを有し、短縁部１０は、角型電池１２の短縁にほぼ等しい長さを有している。この開口部を介して角型電池１２は、電池収容部６内に出し入れされる。
【００２０】
この開口部６の前側の短縁部１０には、２つの接点片１４、１６が形成されている。これら接点片１４、１６は、同一形状の導電金属製であり、角型電池１２の一方の端面に間隔をおいて存在する２つの電極１８、２０と接触するものである。角型電池１２の電極１８と２０とは、図３から明らかなように、その形状が異なり、また、電極２０の寸法が電極１８よりも大きい。本来、接点片１４は電極１８に、接点片１６は電極２０に、それぞれ接触するものである。接点片１４、１６は、電極１８、２０に対応して形状を異ならせていないので、開口部から角型電池１２を電池収容部６内に収容したとき、接点片１４に電極２０を、接点片１６に電極１８を、誤って接続する可能性がある。そこで、寸法の小さい電極１８が接続されるべき接点片１４の両側には、角型電池１２の電極２０の寸法よりも小さい間隔をおいて２つの板状の突部２２、２２が電池収容部６内部側に向かって電池収容部６の底部にほぼ垂直に突出している。この突出量は、接点片１４の突出量よりも多くされている。
【００２１】
このように突部２２、２２を形成しているので、図１（ｂ）に点線で示すような状態から開口部を通って角型電池１２を電池収容部６内に収容したとき、電極２０が接点片１４側に、電極１８が接点片１６側に位置する状態であっても、電極２０が突部２２に接触し、それ以上、角型電池１２が降下することを阻止する。従って、誤って電極２０が接点片１４に、電極１８が接点片１６に接続されることを防止できる。従って、接点片１４、１６には、同一形状のものを使用することができ、コストを低減することができる。
【００２２】
電池収容部６における後ろの短縁部１０側には、舌片２４が設けられている。この舌片２４は、例えば合成樹脂製の細長い板状体であり、その基端部側が、後ろの短縁部１０側にあり、その先端部が前側の短縁部１０側にある。この舌片２４の基端部の裏面側には、図２に示すように、その幅方向に沿って回転軸２６が配置され、かつ固定されている。この回転軸２６は、舌片２４の幅方向（開口部の短縁部１０の沿う方向）の両側に位置するように収容部６の内部に設けられた軸受け２８、２８の上部に、回転自在に支持されている。従って、舌片２４は、回転軸２６の回りに回転自在である。なお、これら軸受け２８、２８に角型電池１２の一方の端面（電極１８、２０が設けられている端面と反対側の端面）が接している。
【００２３】
この回転軸２６に可動手段、例えば付勢手段、具体的には弾性体、より具体的には、コイルスプリング３０が挿通されている。このコイルスプリング３０の一端は、例えば舌片２４に結合され、他端は、一方の軸受け２８に結合されている。このコイルスプリング３０は、舌片２４が図１における時計方向、即ち電池収容部６から離れる方向の付勢力を舌片２４に与えている。図１（ｂ）に示すように、この付勢状態では、角型電池１２が舌片２４と接触せずに、電池収容部６内に出し入れできるように、舌片２４は、かなり開口部から離れた位置にある。この舌片２４の先端部の内面には、当接部材３２が取り付けられている。この当接部材３２は、舌片２４よりも摩擦係数の大きい材質、例えばスポンジやゴム製のものである。
【００２４】
蓋部材４も、本体２と同様に概略円筒状に形成され、その内部に電池収容部６を収容することができるように、中空に形成されている。この蓋部材４の一端部は開放され、他端は閉塞されている。蓋部材４の開放端部からその内部に、電池収容部６が位置するように、本体２の長さ方向に沿って摺動可能である。この蓋部材４の開放端部の内周面には、雌ねじ３４が形成されている。これは、図１（ａ）に示すように、本体部２の電池収容部６よりも前側の外周面に形成された雄ねじ３６と螺合可能なものである。この螺合状態において、電池収容部６が蓋部材２によって被蓋されている。この蓋部材４の少なくとも内周面は、小さな摩擦係数を持つことが望ましい。
【００２５】
この電池固定具では、電池収容部６内に図１（ｂ）に示すように角型電池１２を収容し、角型電池１２の電極１８、２０を対応する接点片１４、１６に接触させた後、蓋部材４を本体２側に摺動させる。この摺動につれて、蓋部材４の開口端部が舌片２４の背面に接触し、スプリングコイル３０の付勢力に抗して、舌片２４を電池収容部６側に押圧する。そして、蓋部材４が電池収容部６を完全に被蓋した状態、即ち雌ねじ３４を雄ねじ３６に螺合させた状態では、図１（ａ）に示すように舌片２４の裏面に設けた当接部材３２が角型電池１２の胴部に押圧され、強固に角型電池１２を電池収容部６の底面に押圧している。
【００２６】
この押圧状態では、当接部材３２は、角型電池１２の中央部よりも幾分軸受け２８に近い位置を押圧している。角型電池１２の中央部よりも電極１８、２０側に近い位置を当接部材３２によって押圧しようとする場合、舌片２４に長いものを使用しなければならず、大きな回転トルクが必要になり、コイルスプリング３０に比較的付勢力の大きなものを使用する必要がある。しかし、角型電池１２の中央部よりも軸受け２８に近い位置を当接する場合、舌片２４の長さが短くなり、小さな回転トルクをコイルスプリング３０が発生すればよいので、付勢力の小さなコイルスプリングを使用することができる。また、舌片２４が長いと、角型電池１２の出し入れの邪魔になるし、材料も余分に必要であり、コストも高くなるし、重量も重くなる。そこで、舌片２４は、短いものとされている。
【００２７】
当接部材３２が弾力を有しているので、角型電池１２の開口部方向に向かう寸法に公差があっても、これを吸収した上で、確実に角型電池１２を固定することができる。また、当接部材３２に摩擦係数の大きな材質のものを使用しているので、角型電池１２と当接部材３２との接触が維持され、強固に電池収容部６内に押圧でき、ワイヤレスマイクロホンが移動しているときに、角型電池１２ががたつくことがない。蓋部材４の少なくとも内周面は、摩擦係数が小さくされているので、舌片２４を蓋部材４の摺動に伴って、速やかに押圧することができ、角型電池１２の収容に支障が生じることがない。しかも、蓋部材４によって電池収容部６を被蓋するための操作を行うと、同時に角型電池１２を舌片２４によって押圧固定することができる。従って、被蓋操作と別に角型電池１２の固定操作を行う必要がなく、作業性が良好である。
【００２８】
また、角型電池１２を交換する場合、雌ねじ３４と雄ねじ３６との螺合を解除し、蓋部材４を後方に摺動させればよい。これによって、舌片２４に対する蓋部材４による押圧が解除され、図１（ｂ）に示すように、舌片２４は、開口部から離れる方向にコイルスプリング３０の付勢力によって回転する。この後、角型電池１２を電池収容部６から取り出して、新たな角型電池１２を電池収容部６に収容するが、この出し入れの間、舌片２４には角型電池１２が接触することがなく、舌片２４が角型電池１２の出し入れの障害になることはない。即ち、角型電池１２の出し入れが容易に行える。
【００２９】
上記の実施形態では、舌片２４は、電池収容部６の後方の短縁部１０側に設けたが、これに代えて、電池収容部６の前方の短縁部１０側に設けることもできる。また、電池収容部６のいずれかの長縁部８側に設けることもできる。また、上記の実施の形態では、舌片２４は電池収容部６内に設けたが、電池収容部６の開口部の長縁部８及び短縁部１０いずれかの上に軸受けを設け、これに舌片２４を回転自在に支持することもできる。
【００３０】
さらに、上記の実施の形態では、舌片２４を合成樹脂で構成し、これにコイルスプリング３０によって付勢力を与えたが、舌片２４を板バネによって形成すれば、コイルスプリング３０が不要になる。同様に、舌片２４を合成樹脂で構成し、この合成樹脂自体の弾性を利用してもコイルスプリング３０を省略できる。コイルスプリング３０は、軸２６に挿通したが、スペースが許せば、コイルスプリング３０の一端を電池収容部６の例えば底部に固定し、他端を舌片２４の適所に固定してもよい。
【００３１】
上記の実施の形態では、可動手段として、コイルスプリング３０による付勢手段を設けたが、可動手段としてはこれに限ったものではなく、舌片の回動手段を設けてもよい。例えば、舌片を蓋部材の摺動方向に沿って配置し、かつ舌片が回転自在となるように舌片の中途を開口部に支持することによって、舌片が開口部及びこれから離れた位置に移動可能に形成し、かつ舌片の基端部に接触部を形成し、この接触部を蓋部材４の内面に接触可能とし、蓋部材が開口部を被蓋していない状態で蓋部材の内面が舌片の基端部の接触部に接触することによって、舌片を開口部から離れた位置に回転させ、蓋部材を開口部の長手縁に沿って摺動させるに従って蓋部材の内面の舌片への接触位置が変化して、舌片を開口部側に回転させ、最終的に蓋部材４が開口部を被蓋した状態において、蓋部材の内面が舌片の先端部を電池側に押圧する構成としてもよい。
【００３２】
或いは、同じく回動手段として、上記と同様に舌片の中途を回転自在に開口部に支持し、舌片の基端部に錘を設け、蓋部材４が開口部を被蓋していない状態では、錘の重力によって舌片を開口部から離れた位置まで回転させ、蓋部材４を長手縁に沿って摺動させると、舌片に蓋部材の内面が接触して、錘の重力に逆らって、舌片を電池側に回転させる構成を採用することもできる。
【００３３】
また、蓋部材４は、本体２の長さ方向に摺動させて、電池収容部６を被蓋するように構成したが、例えば電池収容部６の上方から開口部を被蓋する構成のものも使用することができる。或いは、蓋部材４を電池収容部６の長さ方向の軸の回りに回転可能に構成し、電池収容部６の短縁方向から蓋部材４を摺動させて、開口部を被蓋してもよい。
【００３４】
また、上記の実施の形態では、接点片１４、１６を同一の形状としたが、接点片１４、１６がそれぞれ接続されるべき角型電池１２の電極に対応した形状とすることもできる。
【００３５】
上記の実施の形態では、電池として角型電池を使用したが、これに限ったものではなく、種々の電池にも適用することができる。例えば、角型電池に代えて、円柱状の電池や釦電池等も使用することができる。
【００３６】
【発明の効果】
以上のように、本発明の電池固定具では、電池の出し入れがしやすく、かつ電池のがたつきを抑えることができる。また、角型電池を電池収容部の接点片に誤って接続することを防止することもできる。

BACKGROUND OF THE INVENTION
The present invention relates to a battery fixture for fixing a battery when the battery is accommodated in a device driven by the battery.
[0002]
[Prior art]
Conventionally, in a device driven by a battery, a battery housing portion is provided in the device, and an elastic body such as sponge or rubber is disposed on the inner surface of the battery housing portion, and the backlash of the battery can be absorbed by the elastic body. It was done. Alternatively, using the elasticity of the electrode contacts provided in the battery housing portion, the battery is fixed in the battery housing portion to suppress rattling.
[0003]
[Problems to be solved by the invention]
In general, battery dimensional tolerances are large. When the tolerance is absorbed and an attempt is made to fix the battery in the battery housing portion by utilizing the elasticity of the inner surface of the battery housing portion or the electrode contact, the battery is caught in the battery housing portion and is difficult to put in and out. If it was easy to put in and take out the battery, the rattling of the battery could not be suppressed and the battery could not be fixed.
[0004]
An object of this invention is to provide the battery fixing tool which is easy to take in and out of a battery, and suppressed the shakiness of the battery.
[0005]
[Means for Solving the Problems]
The battery fixture according to the present invention has a battery accommodating portion, which has an opening in the upper part, and the battery is accommodated in the inside from this opening. Various batteries can be used as this battery, for example, a square battery or a cylindrical battery can be used. A lid member is provided so as to be slidable in a certain sliding direction from an uncovered state that does not exist on the opening to a covered state that covers at least the opening and covers the opening. In the non-covered state, the tongue piece protrudes obliquely upward along the sliding direction from the opening and is in contact with the lid member. The tongue piece rotates to the opening side by sliding the lid member from the non-covered state to the covered state, and is pressed against the battery in the covered state.
[0006]
According to this fixture, the lid member presses the tongue piece against the battery in a state where the lid member covers the opening. Therefore, the battery does not rattle in the battery housing portion. In addition, when the lid member does not cover the opening, the tongue piece is located in a direction away from the opening, so that the tongue piece does not interfere with the insertion and removal of the battery, There is no elastic body or the like for pressing and fixing the battery. Accordingly, the battery can be taken in and out quickly.
[0007]
The opening of the battery housing portion has a length dimension substantially equal to the length dimension of the battery, and has a long edge portion facing each other and a length dimension substantially equal to the width dimension of the battery and facing each other. A short edge portion, and the lid member slides from the non-covered state to the covered state along the long edge portion of the opening from one short edge side to the other short edge side. The tongue piece is formed on one short edge side of the opening.
[0009]
If comprised in this way, when covering a battery accommodating part by sliding a cover member along the long edge of an opening part, the component of the force added to the cover member in order to make a cover member slide is carried out. It can be applied to the tongue piece and pressed against the opening side. Therefore, the square battery can be pressed by the tongue piece at the same time as the covering operation is performed, and the workability is improved.
[0010]
A square battery used as a battery has two electrodes having different dimensions on one end face thereof. Two contact pieces to which electrodes of two different dimensions of the prismatic battery are connected can be formed on the short edge portion of the battery housing portion. These two contact pieces may have the same shape. Of these two contact pieces, protrusions are formed on both sides of a contact of a small-sized electrode in the rectangular battery with an interval smaller than the dimension of the large-sized electrode of the rectangular battery.
[0011]
When the two electrodes of the prismatic battery are brought into contact with the two contact pieces of the battery housing part, there is a possibility that the polarities are erroneously connected. In particular, this possibility is high because the prismatic battery is taken in and out through the opening. However, since the protrusions are formed on both sides of the contact piece with which the small size electrode of the square battery comes into contact with a space smaller than the size of the large size electrode of the square battery, the size of the square battery is large. The protrusion prevents the size electrode from being erroneously connected to the contact piece for the small size electrode of the square battery. That is, the erroneous connection of the square battery can be prevented.
[0012]
The tongue piece may be formed such that the friction coefficient on the side in contact with the battery in the covered state is larger than the friction coefficient on the opposite side. If comprised in this way, a tongue piece can fix a battery firmly. Therefore, even if the battery housing part is moved, the battery does not rattle during the movement.
[0013]
Alternatively, the tongue piece may have an elastic contact member having a larger coefficient of friction than the tongue piece on the side of the tongue piece that contacts the battery in the covered state.
[0014]
With this configuration, since the battery can be firmly fixed in the battery housing portion, even if the battery housing portion is moved, the battery does not rattle during movement, and the contact member has elasticity. Further, it is possible to absorb the dimensional tolerance of the battery, particularly the dimensional tolerance in the direction toward the opening, and obtain a tension for pressing the battery.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
A battery fixture according to an embodiment of the present invention is implemented in a wireless microphone as shown in FIG. 1, for example. Of course, it can be applied to other electric devices. This wireless microphone includes a main body 2 and a lid member 4.
[0018]
Although the main body 2 is formed in a substantially cylindrical shape and is not shown in the figure, a microphone and a transmission circuit for transmitting an audio signal collected by the microphone are provided in the first half. A battery housing 6 is provided in the latter half of the main body 2. The battery housing part 6 has a shape in which the upper part of the rear half part of the main body part 2 is removed from the horizontal plane along the central axis along the length direction. The battery accommodating part 6 has an opening in the upper part thereof, and is formed therein so as to accommodate, for example, a JIS standard, IEC standard 6F22, 6LR61 type square battery 12.
[0019]
As shown in FIG. 3, the opening of the battery housing portion 6 has two long edge portions 8 that face each other, and further has two short edge portions 10 that are orthogonal to the long edge portion 8. The long edge 8 has a length slightly longer than the long edge of the square battery 12, and the short edge 10 has a length substantially equal to the short edge of the square battery 12. The prismatic battery 12 is taken in and out of the battery housing 6 through this opening.
[0020]
Two contact pieces 14 and 16 are formed on the short edge 10 on the front side of the opening 6. These contact pieces 14 and 16 are made of conductive metal having the same shape, and are in contact with two electrodes 18 and 20 existing on one end face of the prismatic battery 12 with a space therebetween. As apparent from FIG. 3, the electrodes 18 and 20 of the prismatic battery 12 are different in shape, and the dimensions of the electrode 20 are larger than those of the electrode 18. Originally, the contact piece 14 is in contact with the electrode 18, and the contact piece 16 is in contact with the electrode 20. Since the contact pieces 14 and 16 do not have different shapes corresponding to the electrodes 18 and 20, when the square battery 12 is received in the battery storage portion 6 from the opening, the electrode 20 is connected to the contact piece 14. There is a possibility that the electrode 18 is erroneously connected to the piece 16. Therefore, two plate-like protrusions 22 and 22 are provided on both sides of the contact piece 14 to which the electrode 18 having a small size is to be connected, with a space smaller than the size of the electrode 20 of the square battery 12. 6 protrudes substantially perpendicularly to the bottom of the battery housing 6 toward the inside. This protrusion amount is made larger than the protrusion amount of the contact piece 14.
[0021]
Since the protrusions 22 are formed as described above, when the prismatic battery 12 is accommodated in the battery accommodating portion 6 through the opening from the state shown by the dotted line in FIG. Even when the electrode 18 is located on the contact piece 14 side and the electrode 18 is located on the contact piece 16 side, the electrode 20 is in contact with the protrusion 22 and prevents the prismatic battery 12 from further falling. Therefore, it is possible to prevent the electrode 20 from being erroneously connected to the contact piece 14 and the electrode 18 from being connected to the contact piece 16 by mistake. Accordingly, the contact pieces 14 and 16 having the same shape can be used, and the cost can be reduced.
[0022]
A tongue piece 24 is provided on the rear short edge portion 10 side of the battery housing portion 6. The tongue piece 24 is an elongated plate-like body made of, for example, a synthetic resin, and has a proximal end portion on the rear short edge portion 10 side and a distal end portion on the front short edge portion 10 side. As shown in FIG. 2, a rotating shaft 26 is arranged and fixed on the back side of the base end portion of the tongue piece 24 along the width direction thereof. The rotating shaft 26 is freely rotatable on top of bearings 28, 28 provided inside the housing portion 6 so as to be located on both sides in the width direction of the tongue piece 24 (the direction along the short edge portion 10 of the opening). It is supported by. Therefore, the tongue piece 24 is rotatable around the rotation shaft 26. The bearings 28 and 28 are in contact with one end face of the prismatic battery 12 (the end face opposite to the end face where the electrodes 18 and 20 are provided).
[0023]
A movable means, for example, an urging means, specifically an elastic body, more specifically, a coil spring 30 is inserted into the rotating shaft 26. One end of the coil spring 30 is coupled to, for example, the tongue piece 24, and the other end is coupled to one bearing 28. The coil spring 30 applies an urging force to the tongue piece 24 in the clockwise direction in FIG. 1, that is, in the direction away from the battery housing 6. As shown in FIG. 1B, in this biased state, the tongue piece 24 is considerably opened from the opening so that the prismatic battery 12 can be taken in and out of the battery housing portion 6 without contacting the tongue piece 24. In a remote location. A contact member 32 is attached to the inner surface of the tip of the tongue piece 24. The contact member 32 is made of a material having a larger friction coefficient than the tongue piece 24, for example, sponge or rubber.
[0024]
The lid member 4 is also formed in a substantially cylindrical shape like the main body 2 and is formed hollow so that the battery accommodating portion 6 can be accommodated therein. One end of the lid member 4 is opened and the other end is closed. The lid member 4 is slidable along the length direction of the main body 2 so that the battery accommodating portion 6 is located inside the open end portion of the lid member 4. A female thread 34 is formed on the inner peripheral surface of the open end of the lid member 4. As shown in FIG. 1A, this can be screwed with a male screw 36 formed on the outer peripheral surface of the main body 2 on the front side of the battery housing 6. In this screwed state, the battery housing portion 6 is covered with the lid member 2. It is desirable that at least the inner peripheral surface of the lid member 4 has a small coefficient of friction.
[0025]
In this battery fixture, the rectangular battery 12 is accommodated in the battery accommodating portion 6 as shown in FIG. 1B, and the electrodes 18 and 20 of the rectangular battery 12 are brought into contact with the corresponding contact pieces 14 and 16. Thereafter, the lid member 4 is slid toward the main body 2 side. As this sliding occurs, the opening end portion of the lid member 4 comes into contact with the back surface of the tongue piece 24 and presses the tongue piece 24 toward the battery housing portion 6 against the urging force of the spring coil 30. In the state where the lid member 4 completely covers the battery housing 6, that is, in the state where the female screw 34 is screwed into the male screw 36, the contact member provided on the back surface of the tongue piece 24 as shown in FIG. The contact member 32 is pressed against the body of the square battery 12, and firmly presses the square battery 12 against the bottom surface of the battery housing 6.
[0026]
In this pressed state, the contact member 32 presses a position somewhat closer to the bearing 28 than the central portion of the prismatic battery 12. When the contact member 32 is used to press a position closer to the electrodes 18 and 20 than the central portion of the prismatic battery 12, a long tongue piece 24 must be used, and a large rotational torque is required. It is necessary to use a coil spring 30 having a relatively large urging force. However, when contacting the position closer to the bearing 28 than the central portion of the square battery 12, the length of the tongue piece 24 is shortened and the coil spring 30 only needs to generate a small rotational torque. A spring can be used. Moreover, if the tongue piece 24 is long, it will obstruct the taking in and out of the prismatic battery 12, additional materials will be required, the cost will be high, and the weight will be heavy. Therefore, the tongue piece 24 is short.
[0027]
Since the contact member 32 has elasticity, even if there is a tolerance in the dimension of the square battery 12 in the direction of the opening, the square battery 12 can be securely fixed after absorbing this. . Further, since the contact member 32 is made of a material having a large friction coefficient, the contact between the rectangular battery 12 and the contact member 32 is maintained, and the contact can be firmly pressed into the battery housing portion 6. When the battery is moving, the square battery 12 does not rattle. Since at least the inner peripheral surface of the lid member 4 has a small coefficient of friction, the tongue piece 24 can be pressed quickly as the lid member 4 slides, and there is a hindrance to accommodation of the prismatic battery 12. It does not occur. Moreover, when the operation for covering the battery housing 6 with the lid member 4 is performed, the rectangular battery 12 can be simultaneously pressed and fixed by the tongue piece 24. Therefore, it is not necessary to perform the fixing operation of the prismatic battery 12 separately from the cover operation, and the workability is good.
[0028]
In addition, when the square battery 12 is replaced, the screwing between the female screw 34 and the male screw 36 is released, and the lid member 4 may be slid rearward. Thereby, the pressing by the lid member 4 against the tongue piece 24 is released, and the tongue piece 24 is rotated by the biasing force of the coil spring 30 in the direction away from the opening as shown in FIG. Thereafter, the square battery 12 is taken out from the battery housing portion 6 and a new square battery 12 is housed in the battery housing portion 6, and the tongue battery 24 is in contact with the tongue piece 24 during this loading / unloading. Therefore, the tongue piece 24 does not become an obstacle to the insertion and removal of the prismatic battery 12. That is, the square battery 12 can be easily taken in and out.
[0029]
In the above-described embodiment, the tongue piece 24 is provided on the short edge portion 10 side on the rear side of the battery housing portion 6. Alternatively, the tongue piece 24 may be provided on the short edge portion 10 side on the front side of the battery housing portion 6. . It can also be provided on either long edge 8 side of the battery housing 6. Further, in the above embodiment, the tongue piece 24 is provided in the battery housing portion 6, but a bearing is provided on either the long edge portion 8 or the short edge portion 10 of the opening of the battery housing portion 6. It is also possible to rotatably support the tongue piece 24.
[0030]
Further, in the above embodiment, the tongue piece 24 is made of synthetic resin and applied with a biasing force by the coil spring 30. However, if the tongue piece 24 is formed by a leaf spring, the coil spring 30 becomes unnecessary. . Similarly, the coil spring 30 can be omitted even if the tongue piece 24 is made of synthetic resin and the elasticity of the synthetic resin itself is used. The coil spring 30 is inserted through the shaft 26. However, if space is allowed, one end of the coil spring 30 may be fixed to, for example, the bottom of the battery housing portion 6 and the other end may be fixed to an appropriate position on the tongue piece 24.
[0031]
In the above embodiment, the biasing means by the coil spring 30 is provided as the movable means. However, the movable means is not limited to this, and a tongue piece rotating means may be provided. For example, by arranging the tongue piece along the sliding direction of the lid member and supporting the middle of the tongue piece to the opening so that the tongue piece can rotate, the tongue piece is positioned away from the opening and the opening. And a contact part is formed at the base end of the tongue piece, the contact part can be brought into contact with the inner surface of the lid member 4, and the lid member does not cover the opening. The inner surface of the lid member is brought into contact with the contact portion of the base end portion of the tongue piece, whereby the tongue piece is rotated to a position away from the opening portion, and the lid member is slid along the longitudinal edge of the opening portion to thereby move the inner surface of the lid member. When the contact position of the tongue piece changes, the tongue piece is rotated to the opening side, and finally the lid member 4 covers the opening, the inner surface of the lid member covers the tip of the tongue piece. It is good also as a structure pressed to the side.
[0032]
Alternatively, as the rotating means, the middle of the tongue piece is rotatably supported by the opening portion as described above, a weight is provided at the base end portion of the tongue piece, and the lid member 4 does not cover the opening portion. Then, when the tongue piece is rotated to a position away from the opening by the gravity of the weight and the lid member 4 is slid along the longitudinal edge, the inner surface of the lid member comes into contact with the tongue piece and the gravity of the weight is opposed. Thus, it is possible to adopt a configuration in which the tongue piece is rotated toward the battery side.
[0033]
In addition, the lid member 4 is configured to slide in the length direction of the main body 2 and cover the battery housing portion 6. For example, the lid member 4 is configured to cover the opening from above the battery housing portion 6. Can also be used. Alternatively, the lid member 4 is configured to be rotatable around the longitudinal axis of the battery housing portion 6, and the lid member 4 is slid from the short edge direction of the battery housing portion 6 to cover the opening. Also good.
[0034]
Moreover, in said embodiment, although the contact pieces 14 and 16 were made into the same shape, it can also be made into the shape corresponding to the electrode of the square battery 12 to which the contact pieces 14 and 16 should each be connected.
[0035]
In the above embodiment, a square battery is used as the battery. However, the present invention is not limited to this, and can be applied to various batteries. For example, instead of the square battery, a cylindrical battery, a button battery, or the like can be used.
[0036]
【The invention's effect】
As described above, in the battery fixture of the present invention, the battery can be easily taken in and out and the rattling of the battery can be suppressed. In addition, it is possible to prevent the square battery from being erroneously connected to the contact piece of the battery housing portion.
