Description

本発明は、電池に接続するタブ端子およびそれを用いた電池に関し、特にリセプタクル端子に嵌合するタブ端子およびそれを用いた電池に関する。 The present invention relates to a tab terminal connected to a battery and a battery using the tab terminal, and more particularly to a tab terminal fitted to a receptacle terminal and a battery using the tab terminal.

近年、リチウムイオン電池などの二次電池はポータブル電子機器や電動車両等の電源として広く用いられるようになり、最近では大電流を必要とする機器等にも用いられてきている。   In recent years, secondary batteries such as lithium ion batteries have come to be widely used as power sources for portable electronic devices, electric vehicles, and the like, and have recently been used for devices that require a large current.

二次電池を電源として用いるには、電池の正負極端子から電流を取り出す為に、電線や金属板等の金属導体が用いられており、入出力用のタブ端子は、電池の正負極端子と外部の機器等のプリント基板やコネクタとを接続する為の部品である。   In order to use the secondary battery as a power source, a metal conductor such as an electric wire or a metal plate is used to take out current from the positive and negative terminals of the battery, and the tab terminal for input and output is connected to the positive and negative terminals of the battery. It is a part for connecting printed circuit boards and connectors of external devices.

従来、電池の正負極端子部より電流を引き出す為には、タブ端子等を接続した電線を金属板に半田付けし、金属板を電池の正負極端子部に溶接していたが、例えば１０Ａ以上の大電流を流す為には電線径をより太くする必要があり、電線径が太くなるにつれ、電線および金属板へ逃げる熱量が増え、半田を溶かす時間が長くなり、長時間の加熱により電線の被覆が変形、溶解し、電線の導体が見えてしまう問題や、半田付けを行なうのに長時間を要する等の問題があり、接続部の信頼性及び作業性に問題があった。又、大電流を流す為に、金属板を厚くすると溶接が困難になり（例えば特許文献１参照）、また、異厚の金属板を使用すると、材料のコストアップに繋がるという問題もあった。   Conventionally, in order to draw current from the positive and negative terminal portions of the battery, the electric wires connected to the tab terminals and the like are soldered to the metal plate, and the metal plate is welded to the positive and negative electrode terminal portions of the battery. It is necessary to increase the wire diameter in order to flow a large current.As the wire diameter increases, the amount of heat that escapes to the wire and the metal plate increases, and the time for melting the solder increases. There are problems that the coating is deformed and melted so that the conductor of the electric wire can be seen, and that it takes a long time to perform soldering, and there is a problem in the reliability and workability of the connecting portion. Further, in order to pass a large current, if the metal plate is made thick, welding becomes difficult (see, for example, Patent Document 1), and if a metal plate having a different thickness is used, there is a problem that the cost of the material is increased.

特開２００２−１４１０５１号公報JP 2002-141051 A

従って、本発明の課題は、電池の正負極端子部より大電流を引き出す際に、半田付け作業を行なわずに、簡便な方法で、電池の正負極端子部と接続するタブ端子と、それを用いた電池とを提供することにある。 Accordingly, an object of the present invention is to provide a tab terminal to be connected to the positive and negative electrode terminal portions of the battery by a simple method without performing a soldering operation when a large current is drawn from the positive and negative electrode terminal portions of the battery. It is to provide a used battery .

本発明は、前記の課題解決のため、電池の正負極端子より大電流を引き出す際に接続されるタブ端子の構造を検討した結果なされたものである。   In order to solve the above-mentioned problems, the present invention has been made as a result of examining the structure of a tab terminal connected when a large current is drawn from the positive and negative terminals of a battery.

本発明のタブ端子は、電池接続に用いられ幅広部と幅狭部を有する板状のタブ端子であって、前記幅広部は、電池の正負極端子と接続する接続部を有し、前記幅広部とつながる前記幅狭部は、折り返し重ね合わせて接合された嵌合部をリセプタクル端子との間に有し、前記嵌合部は、前記幅狭部が重なるように該幅狭部を少なくとも１回折り返した重なり部を複数箇所溶接して形成され、前記幅狭部の断面積は、前記幅広部の断面積と同等であることを特徴とする。 The tab terminal of the present invention is a plate-like tab terminal used for battery connection and having a wide part and a narrow part, and the wide part has a connection part connected to the positive and negative terminals of the battery, and the wide terminal the narrow portion to connect with parts are a fitting portion which is joined by overlapping folding possess between receptacle terminal, the fitting portion, at least the said width narrow portion so that the narrow portion overlap It is formed by welding a plurality of overlapping portions that are folded back, and the cross-sectional area of the narrow portion is equal to the cross-sectional area of the wide portion .

また、本発明のタブ端子は、前記幅狭部の幅が前記幅広部の幅の１／５〜４／５であることが好ましく、前記幅狭部の重なり部の全板厚が前記幅広部の板厚の２〜４倍であることが好ましい。
また、本発明の電池は、上記に記載のタブ端子を用いている。
Furthermore, the tab terminal of the present invention preferably has a width before Symbol narrow portion is 1 / 5-4 / 5 of the width of the wide portion, the total thickness of the overlapping portion of the narrow portion is the wide It is preferable that it is 2 to 4 times the plate thickness of the part.
The battery of the present invention uses the tab terminal described above.

本発明によれば、タブ端子は、幅広部が電池の正負極端子と接続され、幅狭部は簡単な折り返し加工した後、折り返し部が電気的に接続され幅狭部の厚さが幅広部の厚さの２倍以上に厚くなり、幅狭部においても大電流を流せるとともに先端の強度が増しリセプタクル端子との嵌合部とすることにより、タブ端子の半田付け作業が不要になり作業工数の短縮及び電線の被覆の変形、溶解、導体の露出を防ぐことができる等の効果がある。すなわち電流に関しては、１０Ａ以上の大電流を連続で流しても、タブ端子の表面温度上昇が８０℃以上にならず、安全性が増すとともに、大電流を流すためのＡＷＧ１４（単線Φ１．６ｍｍ、撚線２ｍｍ2）以上の電線にも容易に接続させる事ができる。 According to the present invention, the tab terminal has a wide portion connected to the positive and negative terminals of the battery, the narrow portion is simply folded, and then the folded portion is electrically connected so that the thickness of the narrow portion is the wide portion. It is thicker than twice the thickness of the wire, allowing a large current to flow even in a narrow part, increasing the strength of the tip, and making it a fitting part with the receptacle terminal, eliminating the need for soldering the tab terminal and man-hours There are effects such as shortening of the wire length, deformation and dissolution of the coating of the electric wire, and prevention of exposure of the conductor. That is, regarding the current, even if a large current of 10 A or more is continuously supplied, the surface temperature rise of the tab terminal does not exceed 80 ° C., safety is increased, and AWG 14 (single wire Φ1.6 mm, It can be easily connected to an electric wire of 2 mm 2 or more.

以下、本発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明のタブ端子を示す図であり、図１（ａ）はリセプタクル端子との関係を示す正面図であり、図１（ｂ）は側面図であり、図１（ｃ）は底面図である。タブ端子１は板体の幅広部１１と幅狭部１３から構成され、幅広部１１の端部に電池の正負極端子と接続する接続部１２を設け、幅狭部１３は板体が折り返された重なり部１５を設け、幅狭部１３の先端にはリセプタクル端子２との嵌合部１４を設けた構成となっている。   FIG. 1 is a view showing a tab terminal of the present invention, FIG. 1 (a) is a front view showing a relationship with a receptacle terminal, FIG. 1 (b) is a side view, and FIG. It is a bottom view. The tab terminal 1 is composed of a wide portion 11 and a narrow portion 13 of a plate, and a connection portion 12 connected to the positive and negative terminals of the battery is provided at the end of the wide portion 11, and the narrow portion 13 is folded back from the plate. The overlapping portion 15 is provided, and the fitting portion 14 with the receptacle terminal 2 is provided at the tip of the narrow portion 13.

次に、本発明のタブ端子の加工方法について説明する。図２は本発明のタブ端子の加工前の正面図であり、図３は本発明のタブ端子の加工工程を示す図で、図３（ａ）はプレス打ち抜き後、図３（ｂ）は折り返し工程、図３（ｃ）は折り返し後、図３（ｄ）は溶接工程を示す斜視図である。本発明のタブ端子の材料は薄い金属板を使用することができ、例えば厚さ０．２〜０．３ｍｍのＮｉ板をプレスにより打ち抜き加工した板体を使用することができる。打ち抜き加工した形状は図２に示すように幅広部１１と幅狭部１３からなり幅広部１１の形状は図２に示すようにＬ字状でもよいし直線状等でもよく任意に設定できる。幅狭部１３は折り返し線１６から先端部を折り返し、重なり部１５を設けることから折り返し線１６に対し対称な部分を設けておくとよい。   Next, the tab terminal processing method of the present invention will be described. FIG. 2 is a front view of the tab terminal of the present invention before processing, FIG. 3 is a diagram showing the tab terminal processing steps of the present invention, FIG. 3 (a) is after stamping, and FIG. 3 (b) is folded. FIG. 3 (c) is a perspective view showing the welding process after FIG. As a material for the tab terminal of the present invention, a thin metal plate can be used. For example, a plate body obtained by punching a Ni plate having a thickness of 0.2 to 0.3 mm by a press can be used. As shown in FIG. 2, the punched shape includes a wide portion 11 and a narrow portion 13, and the shape of the wide portion 11 may be L-shaped or linear as shown in FIG. The narrow portion 13 is preferably provided with a symmetric portion with respect to the folding line 16 because the tip portion is folded from the folding line 16 and the overlapping portion 15 is provided.

図３に示すように、本発明のタブ端子の幅狭部１３の折り返しは幅狭部１３の幅が同一幅に重なるように折り返し線１６から１８０度折り返す（図３（ｂ）、図３（ｃ））。ここで幅狭部１３に折り返し線１６に対称に穴部１７を設けておく。幅狭部に穴部を設けることにより、電線の着脱が可能になり、電線の交換が容易になり、電線破損時に電線の交換が容易になる利点がある。   As shown in FIG. 3, the folding of the narrow portion 13 of the tab terminal of the present invention is folded 180 degrees from the folding line 16 so that the width of the narrow portion 13 overlaps the same width (FIG. 3B, FIG. c)). Here, a hole 17 is provided in the narrow portion 13 symmetrically with respect to the folding line 16. By providing the hole in the narrow portion, it is possible to attach and detach the electric wire, and the electric wire can be easily exchanged, and there is an advantage that the electric wire can be easily exchanged when the electric wire is broken.

次に折り返した幅狭部１３同士を接続するために溶接棒３を用いて折り返された重なり部１５に溶接部１８を複数箇所設けることにより板厚を増して、強度を上げると共に、汎用のリセプタクル端子との嵌合部として使用が可能になる（図３（ｄ））。   Next, a plurality of welded portions 18 are provided in the overlapped portion 15 folded using the welding rod 3 in order to connect the folded narrow portions 13 to each other, thereby increasing the plate thickness, increasing the strength, and general-purpose receptacle. It can be used as a fitting portion with a terminal (FIG. 3D).

幅狭部１３は折り返しの回数により板厚は変わり、折り返し前の幅狭部１３の板厚は幅広部１１の板厚と同じ板厚になることが望ましい。一回の折り返しにより板厚は２倍になり、板厚を４倍を超える厚さとするには折り返しの回数が少なくとも３回必要となり加工工程が煩雑となるためである。また、幅狭部１３の幅は幅広部１１の幅の１／５〜４／５が望ましい。幅狭部１３の幅が１／５より狭い場合には、大電流を流すために断面積を幅広部と同等にするために折り返しが多く必要となり加工工程が煩雑となり、４／５より広い場合には幅狭部と幅広部の幅の差が小さく折り返しにより幅狭部を厚くする必要性が少なくなるためである。   The plate thickness of the narrow portion 13 varies depending on the number of times of folding, and the plate thickness of the narrow portion 13 before folding is preferably the same as the plate thickness of the wide portion 11. This is because the sheet thickness is doubled by one folding, and the number of times of folding is required at least three times to make the thickness more than four times, and the machining process becomes complicated. The width of the narrow portion 13 is preferably 1/5 to 4/5 of the width of the wide portion 11. When the width of the narrow portion 13 is narrower than 1/5, a large current is required to make the cross-sectional area equal to that of the wide portion in order to pass a large current, and the machining process becomes complicated and the width is larger than 4/5. This is because the difference between the width of the narrow portion and the wide portion is small, and the need to thicken the narrow portion by folding is reduced.
