Description

本発明のバッテリパックは、複数の素電池１を電池ホルダー３の定位置に配置している電池のコアパック３０と、このコアパック３０を挿入してなる外装ケース２０とを備える。電池ホルダー３は、素電池１を挿入する挿入筒部４と、コアパック(30)を外装ケース(20)に挿入する挿入方向の垂直断面において、この挿入筒部４から外側に突出する弾性アーム部１４を設けている。バッテリパックは、コアパック３０が外装ケース２０に挿入される状態で、弾性アーム部１４によって、外装ケース２０のコーナー部の内面２０Ａを弾性的に押圧している。
The battery pack of the present invention includes a battery core pack 30 in which a plurality of unit cells 1 are arranged at fixed positions of a battery holder 3, and an outer case 20 in which the core pack 30 is inserted. Battery holder 3 includes an insertion tube section (4) for inserting the unit cell 1, in the insertion direction of the vertical cross section for inserting the core pack (30) to the outer casing (20), the resilient arms projecting from the insertion tube portion 4 to the outside the part 14 are set only. The battery pack elastically presses the inner surface 20 </ b> A of the corner portion of the outer case 20 by the elastic arm portion 14 in a state where the core pack 30 is inserted into the outer case 20.

本発明のバッテリパックは、弾性アーム部１４が挿入方向に横幅が延びるように設けられており、内面２０Ａに弾性的に押圧される押圧ライン１４Ａが挿入方向に延びるようにしてなることができる。また、本発明のバッテリパックは、押圧ライン１４Ａが、挿入方向に向かって内面２０Ａから離れる方向に傾斜してなることができる。
In the battery pack of the present invention, the elastic arm portion 14 is provided so that the lateral width extends in the insertion direction, and the pressing line 14A elastically pressed against the inner surface 20A can extend in the insertion direction. In the battery pack of the present invention, the pressing line 14A can be inclined in a direction away from the inner surface 20A in the insertion direction.

本発明のバッテリパックは、複数の電池ホルダー３を挿入方向に連結してコアパック３０とし、各々の電池ホルダー３は、外装ケース２０に挿入される先端側に第１のセルホルダー３ａを、後端側に第２のセルホルダー３ｂを配置することができる。
以上のバッテリパックは、多数の素電池を収納する電池のコアパックをスムーズに外装ケースに挿入しながら、全ての電池ブロックを自由に移動しない状態で外装ケース内に配置できる。
The battery pack of the present invention connects a plurality of battery holders 3 in the insertion direction to form a core pack 30, and each battery holder 3 has a first cell holder 3 a on the front end side inserted into the outer case 20, The second cell holder 3b can be disposed on the end side.
The battery pack described above can be placed in the exterior case in a state where all the battery blocks are not moved freely while the core pack of the battery storing a large number of unit cells is smoothly inserted into the exterior case.
