Abstract

<P>PROBLEM TO BE SOLVED: To obtain a battery pack with a simple structure in which, while using a recent battery with small projection of a positive electrode terminal, the outside dimensions can be made small as a conventional one only by changing wiring position of a lead wire. <P>SOLUTION: The battery pack has a battery pack 20 in which a plurality of cylindrical batteries 5 are arranged in parallel housed in a heat shrinkage tube 30, and a lead wire is connected to this. A Ni terminal member 22 is installed so as to extract a lead wire at a portion surrounded by a tangent portion of batteries in the same direction as the arrangement direction of the batteries 5, a tangent portion of the batteries at right angles to this at the end part of the tangent portion, a line section in perpendicular direction from the topmost vertex of the right angle, and a circumference portion of these cylindrical batteries, and the lead wire 21 is connected to this terminal member. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

この発明はパック電池に関し、とくに端子片とリード線の接続位置に改良を加えて外形寸法を最小にできるようにしたパック電池に関するものである。   The present invention relates to a battery pack, and more particularly to a battery pack in which the external dimension can be minimized by improving the connection position between a terminal piece and a lead wire.

従来、パック電池に使用されていた電池は、図４に示すように電池５の陽極端子６が外側に比較的に大きく突出した形状の電池５が使用されていた。同図に示すように、従来は電池５の陽極端子６が比較的に大きく外側に出ていたので、陽極端子周辺に比較的大きな空間７がありこの部分を有効に利用して図３（Ａ）および（Ｂ）に示すようにリード線８を配線してパック電池を製作していたものである。   Conventionally, as a battery used for a battery pack, a battery 5 having a shape in which the anode terminal 6 of the battery 5 protrudes relatively large outside as shown in FIG. 4 has been used. As shown in FIG. 3, since the anode terminal 6 of the battery 5 has been relatively large and has been exposed to the outside, there is a relatively large space 7 around the anode terminal. ) And (B), lead wires 8 are wired to produce a battery pack.

しかしながら、最近は電池の形状が変わり、図２に示すように陽極端子１０の突出が少なくなり、陽極端子の周辺に空間が少なくなってしまい従来と同じようにしてリード線を配置すると、この部分でリード線の部分が出っ張って、従来のように外形寸法を小さく押さえたパック電池の製作が困難となってきた。   However, recently, the shape of the battery has changed, and as shown in FIG. 2, the protrusion of the anode terminal 10 is reduced, and the space around the anode terminal is reduced. As a result, the lead wire portion protrudes, making it difficult to produce a battery pack with a reduced outer dimension as in the prior art.

パック電池の従来技術としては、電池ブロックと、リード線と温度検出素子とを電池ケースに収納したパック電池において、温度検出素子はそのリード線が弾力性を有しており、電池ケースには温度検出素子を電池列間の谷間空間に固定する第１のリブ体と、リード線部の固定を行う第２のリブ体を有するパック電池が公知である（例えば、特許文献１）。
特開２０００−２７７０６９号 As a conventional battery pack, in a battery pack in which a battery block, a lead wire and a temperature detection element are housed in a battery case, the lead wire of the temperature detection element has elasticity, and the battery case has a temperature. A battery pack having a first rib body that fixes a detection element in a valley space between battery rows and a second rib body that fixes a lead wire portion is known (for example, Patent Document 1).
JP 2000-277069 A

上記の先行技術によると、確かに電池間の谷間空間にリード線を配置して固定するようにしているので外形寸法を小型化することは可能であるが、しかしこの場合は電池ケースにリブを取り付ける手間が必要となり、形状が複雑で製作コストがかかり問題があった。   According to the above prior art, the lead wire is surely arranged and fixed in the valley space between the batteries, so it is possible to reduce the outer dimension, but in this case, the rib is attached to the battery case. There is a problem in that it takes time and effort to install, the shape is complicated and the manufacturing cost is high.

この発明は構成を簡単にして、リード線の配置位置を変更するだけで、陽極端子の突出が少ない最近の電池を用いたものでも外形寸法を従来と同様に小型化できるようにしたパック電池を得ようとするものである。   The present invention is a battery pack in which the external dimensions can be reduced in the same manner as in the past even with the use of a recent battery that has a simple structure and only changes the position of the lead wire, and the projection of the anode terminal is small. I want to get.

この発明は、複数個の円筒形電池を並置配列した組電池を熱収縮チューブ内に収納しこれにリード線を接続したパック電池において、
電池の配列方向と同じ方向の電池の接線部と、この接線部の端部でこれと直角をなす電池の接線部と、その直角の頂点から垂直方向を向けた線部と、これらと円筒形電池の円周部で囲まれた部分にリード線を取り出せるようにＮｉ端子片を取り付け、この端子片にリード線を接続したことを特徴とするパック電池である。 The present invention relates to a battery pack in which a battery pack in which a plurality of cylindrical batteries are arranged side by side is housed in a heat-shrinkable tube and a lead wire is connected thereto.
The battery tangent part in the same direction as the battery arrangement direction, the battery tangent part perpendicular to it at the end of the tangent part, the line part directed vertically from the apex of the right angle, and these and the cylindrical shape The battery pack is characterized in that a Ni terminal piece is attached to a portion surrounded by a circumferential portion of the battery so that a lead wire can be taken out, and the lead wire is connected to the terminal piece.

この発明によれば、リード線の配置位置を変更するだけで簡単に外形寸法を小型化できるようにしたパック電池を得ることができるものである。また、この発明によればそのために特別に新たな部品も必要としない。さらに、組み立て作業も従来とほぼ同じようにできて安価にパック電池を作製することが可能である。   According to the present invention, it is possible to obtain a battery pack whose outer dimensions can be easily reduced by simply changing the arrangement position of the lead wires. In addition, according to the present invention, no special new parts are required. Further, the assembling work can be performed almost in the same manner as before, and a battery pack can be manufactured at a low cost.

図２は最近使用されている陽極端子の突出が少ない型の電池で、（Ａ）は上面図、（Ｂ）は側面図である。同図に示すように、この電池は図４に示す従来の電池と比べ陽極端子１０の突出は非常に少ない。この電池を用いてこの発明の電池パックとしたものを図１に示した。   2A and 2B show a battery of a type in which the anode terminal protrudes little recently. FIG. 2A is a top view and FIG. As shown in the figure, this battery has very few protrusions of the anode terminal 10 compared to the conventional battery shown in FIG. A battery pack of this invention using this battery is shown in FIG.

図１の（Ａ）は、この発明のパック電池の上面図である。このパック電池では単電池セルを一列電池として組電池２０としたものである。この組電池の一方の陽極端子２３には、電池の配列方向と同じ方向の電池の接線部と、この接線部の端部でこれと直角をなす電池の接線部と、その直角の頂点から垂直方向を向けた線部と、円筒形電池の円周部で囲まれた部分Ａからリード線を取り出せるようにＮｉ端子片２２をスポット溶接で取り付け、この端子片２２にリード線２１を接続する。   FIG. 1A is a top view of a battery pack according to the present invention. In this battery pack, single battery cells are used as a single battery to form a battery pack 20. One anode terminal 23 of the assembled battery has a battery tangent portion in the same direction as the battery arrangement direction, a battery tangent portion perpendicular to the tangential portion end, and a perpendicular from the right apex. The Ni terminal piece 22 is attached by spot welding so that the lead wire can be taken out from the line portion directed in the direction and the portion A surrounded by the circumferential portion of the cylindrical battery, and the lead wire 21 is connected to the terminal piece 22.

次いで、図１（Ｂ）に示すようにリード線２１を組電池２０の側面に沿って図示するようにして折り曲げる。なお、２５は相隣接する電池の陽極端子と陰極を接続する接続片である。   Next, as shown in FIG. 1B, the lead wire 21 is bent along the side surface of the assembled battery 20 as illustrated. Reference numeral 25 denotes a connection piece for connecting an anode terminal and a cathode of adjacent batteries.

組電池２０の他端の陽極端子についても図１（Ｂ）に示すように、同じようにしてリード線２１を、陽極端子の配列方向に対して電池の配列方向と同じ方向の電池の接線部と、この接線部の端部でこれと直角をなす電池の接線部と、その直角の頂点から垂直方向を向けた線部と、円筒形電池の円周部で囲まれた部分Ｂからリード線を取り出せるようにＮｉ端子片をスポット溶接で取り付け、この端子にリード線を接続する。その後、次いで、図１（Ｂ）に示すようにリード線２１を組電池２０の側面に沿って図示するようにして折り曲げる。   As for the anode terminal at the other end of the assembled battery 20, as shown in FIG. 1B, the lead wire 21 is connected in the same manner to the battery tangent portion in the same direction as the battery arrangement direction with respect to the anode terminal arrangement direction. A tangential portion of the battery that is perpendicular to the end of the tangential portion, a line portion that is perpendicular to the apex of the right angle, and a portion B surrounded by the circumferential portion of the cylindrical battery. A Ni terminal piece is attached by spot welding so that the lead wire can be taken out, and a lead wire is connected to this terminal. Thereafter, as shown in FIG. 1B, the lead wire 21 is bent along the side surface of the assembled battery 20 as shown.

その後、リード線２１をある程度の力で引っ張っても耐えられるように、組電池２０の周囲にポリエチレンテープ２９を貼って押さえつけておく。リード線の取り出し位置は電池の高さ方向において、電池高さを超えない範囲から取り出すようにする。なお、陽極側のニッケル端子には短絡保護のために絶縁チューブをかけておくことが好ましい。最後に、熱収縮チューブ３０で全体をパックしてパック電池とする。   Thereafter, a polyethylene tape 29 is pasted around the assembled battery 20 so as to be able to withstand even if the lead wire 21 is pulled with a certain amount of force. The lead wire is taken out from a range not exceeding the battery height in the battery height direction. In addition, it is preferable to cover the anode side nickel terminal with an insulating tube for short circuit protection. Finally, the whole is packed with the heat shrinkable tube 30 to obtain a battery pack.
