Definitions
- This technology relates to a battery pack that can be mounted on an electronic device.
- a battery pack such as a lithium ion secondary battery is detachably mounted on a small electronic device such as a digital still camera, a digital video camera, or a mobile phone.
- Some battery packs include a control terminal for communication and a temperature detection terminal for temperature detection in addition to a plus terminal and a minus terminal.
- Patent Document 1 describes a battery pack having a terminal portion in which a control terminal, a minus terminal, a temperature detection terminal, and a plus terminal are arranged in order in the width direction on the front surface of the battery pack.
- battery packs are often prepared for each type of electronic device, and the arrangement of contacts connected to the terminals of the battery pack is different for each type of electronic device. Therefore, an electronic device to which a battery pack having a temperature detection terminal and a control terminal in addition to a plus terminal and a minus terminal is mounted is connected to each terminal connected to these terminals so as to correspond to the arrangement of each terminal of the battery pack. The sequence is determined.
- the battery pack is not correctly attached to the electronic device, or if the shape of the contact point of the electronic device is defective, the battery pack and the electronic device cannot be properly attached and the electronic device is There is a possibility that it cannot be operated.

And an end surface and first and second side surfaces facing each other in a third axial direction orthogonal to the first and second axial directions.
- the plurality of terminals include a plus terminal, a minus terminal, a temperature detection terminal, and a control terminal arranged on the first end surface along the third axial direction.
- the minus terminal is disposed between the temperature detection terminal and the control terminal so as to be biased toward the control terminal rather than the temperature detection terminal.
- the minus terminal arranged between the temperature detection terminal and the control terminal is arranged more biased toward the control terminal side than the temperature detection terminal side. This prevents a contact on the electronic device side to be connected to the negative terminal from being erroneously connected to the temperature detection terminal, and can stably maintain a state in which the contact is properly connected to the negative terminal. . Thus, normal operation of the electronic device can be ensured.

- the first end surface may include a first recess provided on the first side surface side and a second recess provided on the second side surface side.
- the first and second recesses are arranged at the first end surface so as to be biased toward the second main surface side rather than the first main surface side. Thereby, the function of preventing erroneous insertion of the battery pack can be obtained for the electronic device.
- the terminal may be arranged at the first end face so as to be biased toward the first side face rather than the second side face. Since the symmetry of the terminal is broken with respect to the center line of the first end face parallel to the first axial direction, electrical connection between the terminal and the electronic device at the time of erroneous insertion can be inhibited.
- the first recess may have a larger width dimension in the third axial direction than the second recess.
- the terminal may be arranged at the first end surface so as to be biased toward the first main surface rather than the second main surface. Since the symmetry of the terminal is broken with respect to the center line of the first end face parallel to the third axial direction, electrical connection between the terminal and the electronic device at the time of erroneous insertion can be inhibited.
- the second end surface may have a locking portion configured to be locked to the electronic device.
- the locking portion is disposed at the second end surface so as to be biased toward the second main surface rather than the first main surface.
- the battery pack is mounted on the electronic device while the second end surface is rotated about an axis parallel to the third axial direction in a state where the first end surface is in contact with the electronic device. In such a case, inadvertent detachment of the battery pack from the electronic device can be suppressed.

上記複数の端子は、上記第3の軸方向に沿って上記第1の端面上に各々配列されたプラス端子、マイナス端子、温度検出端子及びコントロール端子を含む。上記マイナス端子は、上記温度検出端子と上記コントロール端子との間に、上記温度検出端子側よりも上記コントロール端子側に偏って配置される。
上記第1の端子窓は、上記コントロール端子を外部へ露出させる。上記第2の端子窓は、上記第1の端子窓と第1の間隙をあけて設けられ、上記マイナス端子を外部へ露出させる。上記第3の端子窓は、上記第2の端子窓と上記第1の間隙よりも大きい第2の間隙をあけて設けられ、上記温度検出端子を外部へ露出させる。上記第4の端子窓は、上記プラス端子を外部へ露出させる。

本実施形態のバッテリパック100は、図2及び図3に示すように、X軸方向に厚み方向、Y軸方向に長さ方向、Z軸方向に幅方向を有する。本実施形態では、厚み方向の寸法(Dx)は9mm±2mm、長さ方向の寸法(Dy)は43mm±2mm、幅方向の寸法(Dz)は30mm±2mmである。一例としては、Dx=9.13mm(+0.37mm、-0.10mm)、Dy=42.64mm(±0.16mm)、Dz=29.85mm±0.15mmである。
本実施形態のバッテリパック100において、トップカバー31は、端子部20の端子21a~21dを外部に露出させる矩形状の複数の端子窓42を有する。
一般に、バッテリパックの端面に取り付けられるカバーに端子窓のような開口部を形成すると、当該カバーの剛性が低下し、例えば落下衝撃等の外力を受けることでカバーの破損を招き易い。
そこで本実施形態では、落下衝撃等に対するトップカバー31の耐久性を高めるため、複数の端子窓42のうちZ軸方向において最も外側に位置する端子窓の一のコーナ部が、当該端子窓の他のコーナ部よりも大きな曲率半径で形成されている。
以上、本技術の実施形態について説明したが、本技術は上述の実施形態にのみ限定されるものではなく、本技術の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
右側面15及び左側面16は、外方に突出する円弧面で形成される構成としたが、これに限らず、円弧面を一部に含む略平面形状や、略平面形状のみから形成される構成でもよい。
端子部20は、Z軸に沿ってコントロール端子、マイナス端子、温度検出端子、プラス端子の順に並んで配置される構成としたが、これに限らず、Z軸に沿ってコントロール端子、プラス端子、温度検出端子、マイナス端子の順に並んで配置される構成でもよい。
トップカバー31は、配線基板21を位置決めする一対の基準ピン311と、配線基板21を固定する一対の固定爪312とを有する構成としたが、これに限らず、基準ピン311と固定爪312が無い構成でもよい。その場合には、配線基板21は、一対の基準ピン311が貫通する一対の貫通孔201aを有していない構成となる。
