Description

【０００１】
【発明の属する技術分野】
本発明は、電池を複数個並べて配置する電池ブロックや、電池ブロックを複数ブロック並べて配置する組電池、さらに組電池を電源として駆動する機器の本体筐体への組電池の固定構造に関するものである。
【０００２】
【従来の技術】
パーソナルコンピュータや携帯電話等の各種電気機器の電源として二次電池が用いられているが、このような機器の小型軽量化に伴って、電源として使用される二次電池の薄型化や軽量化が求められている。
【０００３】
そこで、近年では、薄型で軽量なポリマー電池が用いられるようになってきている。このポリマー電池は、図１に示すように、外装体として樹脂や金属等をラミネートしたシート状材料を用いており、従来のリチウムイオン電池等のように金属製の外装缶を用いないため、薄型で軽量化を図ることができる。
【０００４】
また、このポリマー電池の外装体は、内部に電極体や電解質等の発電要素を包み込んだシート状材料を折り曲げ、突き合わされた縁部を溶着することによって封止する構造になっている。このように一枚のシートを折り曲げて封止する構造のため、電池の電極を取り出した正極端子片と負極端子片とが薄い金属板で形成され、各々正極端子片と負極端子片とは、ポリマー電池本体の一面から同じ方向に突出するように形成されている。
【０００５】
【発明が解決しようとする課題】
このようなポリマー電池を複数個接続してブロック化し、機器の電源として使用する場合、ポリマー電池を積み重ねて配置するよりも、同一平面上に並べて配置することが望ましい。同一平面上に並べて配置すると、ブロック全体の厚みは個々のポリマー電池の厚みと同一となって、薄型のポリマー電池の特徴を生かすことができるからである。
【０００６】
しかしながら、ポリマー電池は、前述の通り、各々の正極端子片と負極端子片とがポリマー電池本体の一面から同じ方向に突出するように形成されているため、複数個接続してブロック化する際、各ポリマー電池間や、ポリマー電池の充放電を制御する保護回路を実装したプリント基板との接続用リード板の配線が困難になる問題がある。特に、正極端子片と負極端子片とが同一面から同じ方向に近接して突出しているために、例えば、複数個の電池を並列接続する場合に、正極と負極とが接触してしまう問題があったり、また、各電池を同一平面で行と列方向にマトリックス状に配置する場合に、プリント基板との接続の際に配線の取り廻しが困難になる問題がある。
【０００７】
従って、この発明は、例えばポリマー電池のような、正極端子片と負極端子片とが電池本体の一面から同じ方向に突出するよう形成された電池を複数個設ける場合に、コンパクトにしながら、接続用リード板の取り廻しが容易でショート等の心配もない組電池を提供するものである。
【０００８】
【課題を解決するための手段】
この発明は、上記課題を解決するために、電池ブロックとして、正極端子片と負極端子片とを各々同一方向に突出させた複数個の電池と、各電池の正極端子片同士を連結する接続用リード板と、負極端子片同士を連結する接続用リード板とを備え、前記複数個の電池が前記端子片の突出方向と直交する方向に並べて配置されることによって、各電池の端子片が互いに平行に配置されて、各接続用リード板が、前記端子片の突出方向と直交する方向に一直線状に配置される。
【０００９】
また、各接続用リード板が、各々異なる絶縁シートに被覆され、各絶縁シートが各接続用リード板を露出する導体露出部を形成しており、露出した接続用リード板と各端子片とが電気接続され、各絶縁シートが重ねて配置されていることを特徴とする。
【００１０】
また、突出長さが異なる正極端子片と負極端子片とを各々同一方向に突出させた複数個の電池と、各電池の正極端子片同士を連結する接続用リード板と、負極端子片同士を連結する接続用リード板とを備え、前記複数個の電池が前記端子片の突出方向と直交する方向に並べて配置されることによって、各電池の端子片が互いに平行に配置されて、各接続用リード板が、前記端子片の突出方向と直交する方向に一直線状に配置される。
【００１１】
また、各接続用リード板が、絶縁シートに一体に被覆され、絶縁シートが各接続用リード板を露出する導体露出部を形成しており、露出した接続用リード板と各端子片とが電気接続され、突出長さの長い方の端子片が、絶縁シートを介して短い方の端子片と接続された接続リード板を横切って配置されていることを特徴とする。
【００１２】
一方、本発明の組電池として、請求項１または２記載の電池ブロックを複数ブロック並べて、各電池ブロックと隣接してプリント基板を配置し、各電池ブロックの接続用リード板の先端を絶縁シートから露出して、接続用リード板の各先端と前記プリント基板とが連結されていることを特徴とする。
【００１３】
そして、前記組電池を電源として駆動する機器の本体筐体に対して、両面テープを用いて組電池を固定したことを特徴とする。
【００１４】
また、前記組電池を電源として駆動する機器の本体筐体に位置決め突起を形成して前記組電池を本体筐体に固定したことを特徴とする。
【００１５】
【発明の実施の形態】
本発明の実施例を図面に基づき説明する。本発明は、ポリマー電池１を複数個連結して電池ブロック２とし、さらに、電池ブロック２を複数ブロック連結して組電池３としている。
【００１６】
ポリマー電池１は、前述の通り、外装体として樹脂や金属等をラミネートしたシート状材料を用いており、従来のリチウムイオン電池等のように金属製の外装缶を用いないため、薄型で軽量化を図ることができる。また、このポリマー電池１の外装体は、内部に電極体や電解質等の発電要素を包み込んだシート状材料を折り曲げ、突き合わされた縁部を溶着することによって封止する構造になっている。このように一枚のシートを折り曲げて封止する構造のため、電池の電極を取り出した正極端子片１１と負極端子片１２とが薄い金属板で形成され、各々正極端子片１１と負極端子片１２とは、ポリマー電池１本体の一面から同じ方向に突出するように形成されている。
【００１７】
また、図１では、正極端子片１１は負極端子片１２よりも長く形成されている。このように正極端子片１１と負極端子片１２との長さを異ならせることによって、正極と負極とを識別して容易に認識することができる。また、正極端子片１１はアルミニウム、負極端子片１２はニッケルの板状に形成されており、素材の光沢や強度等の違いによっても識別することができる。尚、正極端子片と負極端子片との長さは同じ長さにしてもよく、その場合は、各端子片を同時に裁断することができるので、製造工程を少なくすることができる。
【００１８】
次に、図２及び図３は前記ポリマー電池１を複数個連結した電池ブロックを示している。図２に示す電池ブロック２は、薄い略直方体状に形成されたポリマー電池１を側面の短手方向で、前記正極端子片１１及び負極端子片１２の突出方向と直交する方向に４個並べている。このため、電池ブロック２全体の厚みは個々のポリマー電池１の厚みと同じで非常に薄く形成されている。
【００１９】
電池ブロック２は、４個のポリマー電池１を並列に接続している。このため、細い接続用リード板２１を２枚用いて、個々のポリマー電池１の正極端子片１１同士、及び負極端子片１２同士を互いに電気接続している。そして、２枚の接続用リード板２１は一直線状に形成されて、各端子片１１、１２と直交する方向に互いに平行に並べられている。従って、各電池１をコンパクトで容易に接続でき、接続用リード板２１によって、簡単に電池１の出力を取り出すことができる。
【００２０】
絶縁シート２２は、接続用リード板２１を被覆されている。絶縁シート２２は上下２枚の間に接続用リード板２１を挟んで熱溶着等によりラミネートして一体化されている。図２に示す絶縁シート２２は、平行に並べた２枚の接続用リード板２１を一体的に被覆しており、一方、図３に示す絶縁シート２２は、各接続用リード２１を別々にして各々被覆している。図３のように別々に被覆することで、各接続用リード板２１を上下に重ねて配置することができるから、その分だけさらに小型化することができる。
【００２１】
絶縁シート２２は、接続用リード板２１と各端子片１１、１２とが接続される領域において、接続用リード板２１が露出する導体露出部２３を形成し、露出した接続用リード板２１と各端子片１１、１２とがスポット溶接されることで電気接続される。
【００２２】
このように、絶縁シート２２は接続用リード板２１を被覆して、端子片同士や、２枚の接続用リード板２１間のショート等を防止することができる。また、接続用リード板２１の先端は絶縁シート２２から露出して、電池ブロック２としての出力を取り出すことができるようになっている。
【００２３】
次に、図４は前記電池ブロック２を複数ブロック組み合わせて組電池３とし、使用される機器の本体筐体４に装着された状態を示している。また、図５は組電池のブロック回路図を示している。図４に示す組電池３は、電池ブロック２を３ブロック並べて配置し、且つポリマー電池１の充放電を制御する保護回路を実装したプリント基板３１を有している。各電池ブロック２は電池１の長手方向に３列並べられて、ちょうど１２個の電池が４行３列のマトリックス状に配置されるようになっている。そして、プリント基板３１は細長い略長方形に形成されて、３列の各電池ブロック２と隣接して配置されている。
【００２４】
また、電池ブロック２に設けられた前記接続用リード板２１の先端はプリント基板３１の導電パターンに接続されることによって各電池ブロック２が直列に接続され、その結果、各ポリマー電池１は４個の並列接続のブロックを３ブロック直列接続される。尚、各ブロックを並列に接続して、１２個の電池１を全て並列に接続することもできる。このように、組電池３は各電池ブロック２を並行に並べて隣接したプリント基板３１にコンパクトに接続することができ、リード板の取り廻しを極めて簡単に行うことができる。
【００２５】
このようにして組み立てられた組電池３は、使用される機器の本体筐体４に装着される。図４における機器はパーソナルコンピュータで、その本体筐体４の内壁に直接組電池３が両面テープで貼り付けられる。また、本体筐体４には組電池３の位置決め用突起４１が形成されており、組電池３を定位置に位置決めすることができる。このように組電池３は薄型のポリマー電池１を同一平面に並べたものであるから、全体として薄型で、また、組電池３を機器の大型化を招かないようになっている。
【００２６】
【発明の効果】
本発明によれば、複数個の電池を組み合わせて電池ブロックを構成する場合に、各電池をコンパクトにまとめて、電池間を容易に電気接続することができると共に、電池ブロック全体の出力についても簡単に取り出すことができる。また、各電池の端子片同士を接続する接続用リード板を絶縁シートで被覆しているので、接続用リード板や端子片間でのショートを防止することができる。さらに、複数の電池ブロックと各電池ブロックと隣接配置されるプリント基板とを備えて組電池を構成し、各電池ブロックの接続用リード板を隣接するプリント基板に接続しているから、簡単に電池とプリント基板とを接続することができて、リード板等の配線の取り廻しが容易に行える。また、この組電池を使用される機器の本体筐体に装着する際にも、便利で手軽に位置決め固定することができ、且つ、同一平面上にマトリックス状に各電池が配置されているので、組電池全体としても薄型に形成することができ、例えばポリマー電池のような薄型の電池を用いた場合、薄型電池の特徴をそのまま生かすことができて、装着する機器の大型化を招いてしまうこともない。

[0009]
Each connecting lead plate is covered with a different insulating sheet, and each insulating sheet forms a conductor exposed portion that exposes each connecting lead plate, and the exposed connecting lead plate and each terminal piece are It is electrically connected, and each insulating sheet is arranged so as to overlap .
[0010]
Also, a plurality of batteries in which positive electrode terminal pieces and negative electrode terminal pieces having different protruding lengths are protruded in the same direction, a connecting lead plate for connecting the positive electrode terminal pieces of each battery, and negative electrode terminal pieces A plurality of batteries arranged side by side in a direction perpendicular to the protruding direction of the terminal pieces, so that the terminal pieces of each battery are arranged in parallel to each other, Lead plates are arranged in a straight line in a direction orthogonal to the protruding direction of the terminal pieces.
[0011]
In addition, each connecting lead plate is integrally covered with an insulating sheet, and the insulating sheet forms a conductor exposed portion that exposes each connecting lead plate, and the exposed connecting lead plate and each terminal piece are electrically connected. A terminal piece having a longer protruding length is connected across a connecting lead plate connected to the shorter terminal piece via an insulating sheet .
[0012]
On the other hand, as the assembled battery of the present invention, a plurality of the battery blocks according to claim 1 or 2 are arranged, a printed circuit board is arranged adjacent to each battery block, and the tip of the connection lead plate of each battery block is separated from the insulating sheet Each of the leading ends of the connecting lead plate and the printed circuit board are connected to each other.
[0013]

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. In the present invention, a plurality of polymer batteries 1 are connected to form a battery block 2, and a plurality of battery blocks 2 are connected to form an assembled battery 3.
[0016]
As described above, the polymer battery 1 uses a sheet-like material laminated with resin, metal, or the like as an exterior body, and does not use a metal exterior can unlike conventional lithium ion batteries, so it is thin and lightweight. Can be achieved. Further, the exterior body of the polymer battery 1 has a structure in which a sheet-like material enclosing an electric power generation element such as an electrode body or an electrolyte is folded and sealed by welding the abutted edges. Thus, because of the structure in which one sheet is folded and sealed, the positive electrode terminal piece 11 and the negative electrode terminal piece 12 from which the battery electrode is taken out are formed of thin metal plates, and the positive electrode terminal piece 11 and the negative electrode terminal piece, respectively. 12 is formed so as to protrude in the same direction from one surface of the polymer battery 1 main body.
[0017]
In FIG. 1, the positive electrode terminal piece 11 is formed longer than the negative electrode terminal piece 12. Thus, by making the lengths of the positive electrode terminal piece 11 and the negative electrode terminal piece 12 different, the positive electrode and the negative electrode can be identified and easily recognized. Further, the positive electrode terminal piece 11 is formed in a plate shape of aluminum and the negative electrode terminal piece 12 is formed in a plate shape of nickel, and can be identified by a difference in gloss or strength of the material. In addition, the length of the positive electrode terminal piece and the negative electrode terminal piece may be the same length. In this case, since each terminal piece can be cut simultaneously, the manufacturing process can be reduced.
[0018]
2 and 3 show a battery block in which a plurality of the polymer batteries 1 are connected. In the battery block 2 shown in FIG. 2, four polymer batteries 1 formed in a thin, substantially rectangular parallelepiped shape are arranged in the lateral direction of the side surface in a direction perpendicular to the protruding direction of the positive electrode terminal piece 11 and the negative electrode terminal piece 12. . For this reason, the thickness of the whole battery block 2 is the same as the thickness of each polymer battery 1, and is formed very thin.
[0019]
The battery block 2 connects four polymer batteries 1 in parallel. For this reason, two thin lead plates 21 for connection are used to electrically connect the positive electrode terminal pieces 11 and the negative electrode terminal pieces 12 of each polymer battery 1 to each other. The two connecting lead plates 21 are formed in a straight line and are arranged in parallel to each other in a direction orthogonal to the terminal pieces 11 and 12. Therefore, each battery 1 can be easily connected in a compact manner, and the output of the battery 1 can be easily taken out by the connecting lead plate 21.
[0020]
The insulating sheet 22 is covered with a connecting lead plate 21. The insulating sheet 22 is integrated by laminating the connecting lead plate 21 between the upper and lower sheets by heat welding or the like. The insulating sheet 22 shown in FIG. 2 integrally covers two connecting lead plates 21 arranged in parallel, whereas the insulating sheet 22 shown in FIG. 3 has each connecting lead 21 separately. Each is coated. By separately covering as shown in FIG. 3, the connection lead plates 21 can be arranged one above the other so that the size can be further reduced accordingly.
[0021]
The insulating sheet 22 forms a conductor exposed portion 23 where the connection lead plate 21 is exposed in a region where the connection lead plate 21 and each terminal piece 11, 12 are connected. The terminal pieces 11 and 12 are electrically connected by spot welding.
[0022]
As described above, the insulating sheet 22 covers the connection lead plate 21 and can prevent short-circuiting between the terminal pieces or between the two connection lead plates 21. Further, the tip of the connecting lead plate 21 is exposed from the insulating sheet 22 so that the output as the battery block 2 can be taken out.
[0023]
Next, FIG. 4 shows a state in which a plurality of blocks of the battery block 2 are combined to form an assembled battery 3 and mounted on a main body housing 4 of the device to be used. FIG. 5 shows a block circuit diagram of the assembled battery. The assembled battery 3 shown in FIG. 4 includes a printed circuit board 31 on which three blocks of battery blocks 2 are arranged and a protection circuit for controlling charging / discharging of the polymer battery 1 is mounted. Each battery block 2 is arranged in three columns in the longitudinal direction of the battery 1, and exactly 12 batteries are arranged in a matrix of 4 rows and 3 columns. The printed circuit board 31 is formed in an elongated, substantially rectangular shape and is disposed adjacent to each battery block 2 in three rows.
[0024]
Further, the tip of the connection lead plate 21 provided in the battery block 2 is connected to the conductive pattern of the printed circuit board 31 so that the battery blocks 2 are connected in series. As a result, each polymer battery 1 has four pieces. Three blocks connected in parallel are connected in series. In addition, it is also possible to connect all the twelve batteries 1 in parallel by connecting each block in parallel. As described above, the assembled battery 3 can be compactly connected to the adjacent printed circuit board 31 with the battery blocks 2 arranged in parallel, and the lead plate can be handled very easily.
[0025]
The assembled battery 3 assembled in this way is attached to the main body housing 4 of the device to be used. The device in FIG. 4 is a personal computer, and the assembled battery 3 is directly attached to the inner wall of the main body housing 4 with a double-sided tape. In addition, a positioning projection 41 for the assembled battery 3 is formed on the main body casing 4 so that the assembled battery 3 can be positioned at a fixed position. As described above, the assembled battery 3 is formed by arranging the thin polymer batteries 1 on the same plane. Therefore, the assembled battery 3 is thin as a whole, and the assembled battery 3 does not increase the size of the device.
[0026]
【The invention's effect】

Can be taken out. Moreover, since the connecting lead plate for connecting the terminal pieces of each battery is covered with the insulating sheet, a short circuit between the connecting lead plate and the terminal pieces can be prevented.
