Description
【０００１】[0001]
本発明は、密閉式電池に関するものである。 The present invention relates to a sealed battery.
【０００２】[0002]
密閉式円筒型電池は、通常図２に示すように安全弁６が電槽缶の中央にあり、 これが電槽缶側の端子を兼ねる構造となっている。このため、この端子の形状は 限られたものとなり、電槽缶側に高強度の端子を形成することが困難であった。 例えば、複数個のセルを接続する場合、強度が低いためにセル間連接用の端子を 別途形成する必要があり、接続法が制限されたり、この端子の分だけエネルギー 密度が低下する欠点を有する。 また、電池間の接続は通常この端子と電池の底が接触することで達成されてい るが、この方法は接触抵抗が大きく問題であった。 In the sealed cylindrical battery, the safety valve 6 is normally located at the center of the battery case as shown in FIG. 2, and this structure also serves as a terminal on the battery case side. Therefore, the shape of this terminal is limited, and it is difficult to form a high-strength terminal on the side of the battery case. For example, when connecting a plurality of cells, it is necessary to separately form a terminal for connecting the cells due to the low strength, and there are drawbacks that the connection method is limited and the energy density is reduced by this terminal. . In addition, the connection between batteries is usually achieved by making contact between this terminal and the bottom of the battery, but this method has a problem of large contact resistance.
【０００３】[0003]
本考案が解決しようとする課題は、密閉式電池が有する上記欠点、即ち電槽缶 側の高強度端子の形成と電池間の接触抵抗の低減という点である。 The problem to be solved by the present invention is the above-mentioned drawback of the sealed battery, that is, the formation of high-strength terminals on the side of the battery case and the reduction of contact resistance between the batteries.
【０００４】[0004]
本考案の密閉式電池は、図１に示す如く、電槽蓋４に棒端子１がねじ状に形成 され、安全弁３が棒端子１から独立した位置にあり、電槽缶底部に接続用端子２ を有することを特徴とするものである。 In the sealed battery of the present invention, as shown in FIG. 1, a rod terminal 1 is formed in a screw shape on a battery case lid 4, a safety valve 3 is located independently of the rod terminal 1, and a connecting terminal is provided on the bottom of the battery case. It is characterized by having 2.
【０００５】[0005]
安全弁が電槽蓋の中央にない電槽蓋を用いることにより、端子の形状を任意に 変化させることが可能となる。そこで、電槽蓋中央に棒端子を形成し、ねじ状と する。図３に示すようにナットを用いてねじ状の棒端子１に接続用端子２を接続 することにより接触抵抗を低減する。 By using a battery case lid where the safety valve is not in the center of the battery case lid, the shape of the terminal can be changed arbitrarily. Therefore, a rod terminal is formed in the center of the battery case lid to form a screw shape. As shown in FIG. 3, the contact resistance is reduced by connecting the connecting terminal 2 to the threaded rod terminal 1 using a nut.
【０００６】[0006]
以下、本考案の実施例を説明する。 図１、図４に本考案の実施例を示す。安全弁３を電槽側端子から独立させるこ とにより、端子形状を金属棒に変化させ、この金属棒をネジ状に加工する。電槽 缶の底部に接続用端子２を溶接する。接続用端子２の中央は編み線５とし、柔軟 な構造とする。これにより、図３に示すような電池間の接続が可能となる。 Embodiments of the present invention will be described below. 1 and 4 show an embodiment of the present invention. By making the safety valve 3 independent from the battery case side terminal, the terminal shape is changed to a metal rod, and this metal rod is processed into a screw shape. Weld the connecting terminal 2 to the bottom of the battery case. A braided wire 5 is formed at the center of the connecting terminal 2 to have a flexible structure. This enables the connection between the batteries as shown in FIG.
【０００７】[0007]
上述した如く、安全弁３を電槽側端子から独立させることにより電槽蓋中央に 高強度ねじ状の棒端子１を形成し、またその電槽缶底部に接続用端子２を形成す ることにより、端子の形成と接続による接触抵抗を低減した密閉式電池を提供す ることができるので、その工業的価値は極めて大である。 As described above, by forming the safety valve 3 independently from the battery case side terminal, the high-strength screw-shaped rod terminal 1 is formed at the center of the battery case lid, and the connecting terminal 2 is formed at the bottom of the battery case can. Since it is possible to provide a sealed battery with reduced contact resistance due to the formation and connection of terminals, its industrial value is extremely large.
