Description

【０００１】
【発明の属する技術分野】
本発明は、鉛電池の正極端子および負極端子と外部の端子接続体との接続方法に関する。
【０００２】
【従来の技術】
鉛電池における正極および負極端子は、多くの場合、蓋上面から突出して外部接続端子と接続されている。しかし、最近、機器内の狭い空間に鉛電池が配置され、体積効率に優れた鉛電池が要求されるようになってきた。そのため、前記端子が蓋上面からできるだけ突出せずに外部端子と接続されるようになっている。このような接続構造を得るため、例えば図４に示すように、先ず、上面が露出して下面や側面が蓋１に埋設されたブッシング２の貫通孔３に、電槽のセル室に収納された極群のストラップ４から立ち上がる端子極柱５の先端部を前記貫通孔３の上端から殆ど突出しない程度に挿入して該ブッシング２と端子極柱５を溶接し、次いで、図５に示すように板状の端子接続体６をその貫通孔７が端子極柱５の真上に位置するように当接して、該貫通孔７上部から足し鉛しながらバーナー等により溶接していた。
【０００３】
【発明が解決しようとする課題】
しかし、この方法によれば、図５に示すようにブッシング２と端子極柱５の接続部上面８が平滑な水平面にならず、端子接続体６を当接した際、ブッシング２の上面と端子接続体６との間に隙間が生じ、また、端子接続体６が水平にブッシング２に当接せずに、溶接不良の原因となった。これを防止するために、ブッシング２と端子極柱５の接続部上面を平滑な水平面にする作業が必要であった。
【０００４】
本発明は、上記問題点に鑑みてなされたものであり、その目的とするところは、前記接続部を平滑にする作業をなくすと共に、端子接続体と前記接続部との溶接不良をなくすことにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明は、ブッシング２の端子貫通孔３に、電槽のセル室に収納された極群のストラップ４から立ち上がる端子極柱５の先端部を挿入し、該ブッシング２は、上面が露出して蓋１に埋設され、該上面に前記貫通孔３を囲む溝２０が形成されているものであり、
次いで、前記溝２０に筒状カバー９の下部をはめ込み、該カバー９内で前記貫通孔３周辺のブッシング２と端子極柱５の先端部を溶融し、該ブッシング２と端子極柱５を接続し、
次いで、前記カバー９を取り除いた後、前記ブッシング２の外側上面２２に貫通孔７を有する端子接続体６を当接し、該貫通孔７に足し鉛しながら前記ブッシング２と端子極柱５の接続部に端子接続体６を溶接することを特徴とする。
【０００６】
また、前記溝２０を挟む内側上面２１の高さを前記ブッシング２と前記端子極柱５を接続する前では前記外側上面２２より高くして足し鉛を不要とし、接続後では前記外側上面２２より低くして端子接続体６がブッシング２と極柱５との接続部に当たらなくすることが好ましい。
【０００７】
【発明の実施の形態】
以下、本発明の一実施形態について図面を参照して説明する。
【０００８】
図１は本発明に係るブッシングと端子極柱の接続方法を示す説明図、図２は本発明に係るブッシングと端子極柱の接続部に端子接続体を接続する方法を示す説明図、図３は本発明により接続した端子部の断面図である。
【０００９】
本発明は、予めブッシング２を埋設した蓋１を用意する。ブッシング２は、中央に円筒形の貫通孔３が形成され、上面と側面の極一部が蓋上面から露出し、下面と側面の殆どが蓋に埋設されている。また、ブッシング２は、上面に円形の溝２０が形成され、この溝２０から外側の上面２２が水平な平滑面であり、内側の上面２１が外側の上面２２より高く形成されている。この高さは、後にブッシング２と端子極柱５が溶接される時に、それらの隙間に該ブッシングの内側上面２１が溶けて埋めるに充分な量となるように設計されたものである。また、蓋１に埋設されたブッシング２側面が凹凸形状になり、蓋とブッシングの接触面の液密性と気密性を確保している。
【００１０】
このようなブッシング２の貫通孔３に、電槽内に収納された極群のストラップ４から立ち上がる円柱形の端子極柱５の先端部を挿入する。挿入後は、図１に示すように、端子極柱５の上面が貫通孔３の上面に達せず、端子極柱５の側面に貫通孔３の下端が接触した状態となり、貫通孔３と極柱５の隙間は上に行くに従い広くなっている。そして、図１のように前記溝２０に筒状カバー９の下端を嵌め込む。該カバー９は、耐熱性の例えばアルミニウムなどからなっている。その後カバー９内で前記極柱５の先端部とブッシング２を溶融して両者を接続する。接続後の状態は、図２のように接続部上面８がブッシング２の外側上面２２より低く、凹凸形状になっている。
【００１１】
次に、図２のようにブッシング２の上方から平板状の端子接続体６を載置する。接続体６は、一端に円形の貫通孔７が形成され、図示しないが他端が接続線と繋がっている。ブッシング２の上に接続体６を載せた状態は、図３から分かるようにブッシング２の外側上面に接続体６の下面が当接し、極柱５の上に接続体６の貫通孔７が配置される。このような状態で、貫通孔７の上方から足し鉛しながらバーナーでブッシング２と極柱５の接続部に接続体６を溶着する。その後、溶着面を平にして本発明の端子接続方法を終える。
【００１２】
なお、ブッシング２と端子極柱５を接続する場合、溶融鉛が電池内に垂れ落ちないように、例えば本出願人が出願した特願平１１−８５７７７号に記載されている筒状体を両者の隙間に嵌め込んで溶接してもよい。
【００１３】
また、本実施形態では、接続部上面８がブッシング２の外側上面２２より低くなるようにしたが、接続体６の貫通孔７の径が接続部上面８の幅より大きければ低くする必要がない。しかし、どのような接続体６にでも対応できるには、本実施形態が好ましい。
【００１４】
以上のように、ブッシング２と端子極柱５を接続する際、カバー９により溝２０の外側上面２２が溶融しないので、平滑な水平面が維持できる。そして、この面２２に端子接続体６の下面を当接してブッシングと極柱の接続部と接続体を隙間なく、また、接続体６と蓋１の上面が平行になるよう溶接できる。
【００１５】
さらに、ブッシング２と接する蓋上面が火によって変形または溶融し、ブッシング２と蓋１の間に隙間ができることがないので、気密性や液密性が損なわれることがない。
【００１６】
【発明の効果】
以上説明した通り、本発明の請求項１によれば、ブッシングと端子極柱の接続部上面に接続体を水平に配置でき、前記接続部と接続体の間を隙間なく接続できる。従って、端子接続部の強度が優れたコンパクトな鉛電池を提供できる。また、従来行われていた前記接続部上面の平滑作業をなくすことができる。さらに、ブッシングと蓋の気密性や液密性が損なわれることがない。
【００１７】
また、請求項２によれば、ブッシングと極柱の溶接時に足し鉛する必要がない。また、これらの接続部に接続体を溶接する際、接続部上面が接続体下面に当たらないので、接続体を水平に維持して確実に溶接できる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for connecting a positive electrode terminal and a negative electrode terminal of a lead battery to an external terminal connector.
[0002]
[Prior art]
In many cases, the positive electrode and the negative electrode terminal in the lead battery project from the upper surface of the lid and are connected to the external connection terminal. However, recently, a lead battery has been placed in a narrow space in a device, and a lead battery excellent in volumetric efficiency has been required. Therefore, the terminal is connected to the external terminal without protruding as much as possible from the upper surface of the lid. In order to obtain such a connection structure, for example, as shown in FIG. 4, first, the upper surface is exposed and the lower surface and side surfaces are accommodated in the through hole 3 of the bushing 2 embedded in the lid 1 in the cell chamber of the battery case. The tip of the terminal pole column 5 rising from the strap 4 of the pole group is inserted so that it hardly protrudes from the upper end of the through hole 3, and the bushing 2 and the terminal pole column 5 are welded, and then as shown in FIG. The plate-like terminal connecting body 6 was abutted so that the through hole 7 was positioned directly above the terminal pole column 5, and was welded with a burner or the like while adding from above the through hole 7 and leading.
[0003]
[Problems to be solved by the invention]
However, according to this method, as shown in FIG. 5, the upper surface 8 of the bushing 2 and the terminal pole column 5 do not have a smooth horizontal surface and the upper surface of the bushing 2 and the terminal are brought into contact with the terminal connector 6. A gap was formed between the connecting body 6 and the terminal connecting body 6 did not abut against the bushing 2 horizontally, resulting in poor welding. In order to prevent this, it is necessary to make the upper surface of the connection portion between the bushing 2 and the terminal pole column 5 a smooth horizontal surface.
[0004]
The present invention has been made in view of the above problems, and its object is to eliminate the work of smoothing the connecting portion and to eliminate welding defects between the terminal connecting body and the connecting portion. is there.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention inserts the tip end of a terminal pole column 5 rising from the strap 4 of the pole group housed in the cell chamber of the battery case into the terminal through hole 3 of the bushing 2, 2, the upper surface is exposed and embedded in the lid 1, and a groove 20 surrounding the through hole 3 is formed on the upper surface.
Next, the lower part of the cylindrical cover 9 is fitted into the groove 20, the bushing 2 around the through hole 3 and the tip of the terminal pole column 5 are melted in the cover 9, and the bushing 2 and the terminal pole column 5 are connected. And
Next, after removing the cover 9, the terminal connecting body 6 having the through hole 7 is brought into contact with the outer upper surface 22 of the bushing 2, and the bushing 2 and the terminal pole column 5 are connected while being added to the through hole 7. The terminal connector 6 is welded to the portion.
[0006]
Further, the height of the inner upper surface 21 sandwiching the groove 20 is made higher than that of the outer upper surface 22 before connecting the bushing 2 and the terminal pole 5, so that lead is not required and after connection, the height of the inner upper surface 21 is higher than that of the outer upper surface 22. It is preferable that the terminal connection body 6 does not come into contact with the connection portion between the bushing 2 and the pole column 5 by lowering.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0008]
FIG. 1 is an explanatory view showing a connection method between a bushing and a terminal pole according to the present invention, FIG. 2 is an explanatory view showing a method of connecting a terminal connector to a connection portion between the bushing and the terminal pole according to the present invention, and FIG. These are sectional drawings of the terminal parts connected by the present invention.
[0009]
In the present invention, a lid 1 in which a bushing 2 is embedded in advance is prepared. The bushing 2 is formed with a cylindrical through-hole 3 in the center, the poles on the upper surface and side surfaces are exposed from the upper surface of the lid, and most of the lower surface and side surfaces are embedded in the lid. Further, the bushing 2 has a circular groove 20 formed on the upper surface, an outer upper surface 22 that is a horizontal smooth surface from the groove 20, and an inner upper surface 21 that is higher than the outer upper surface 22. This height is designed so that when the bushing 2 and the terminal pole column 5 are later welded, an amount sufficient to melt and fill the inner upper surface 21 of the bushing in the gap therebetween. Further, the side surface of the bushing 2 embedded in the lid 1 has an uneven shape, and the liquid-tightness and air-tightness of the contact surface between the lid and the bushing are ensured.
[0010]
A tip end portion of a cylindrical terminal pole column 5 rising from a strap 4 of a pole group housed in the battery case is inserted into the through hole 3 of the bushing 2. After the insertion, as shown in FIG. 1, the upper surface of the terminal pole column 5 does not reach the upper surface of the through hole 3, and the lower end of the through hole 3 is in contact with the side surface of the terminal pole column 5. The gap between the pillars 5 becomes wider as it goes up. Then, the lower end of the cylindrical cover 9 is fitted into the groove 20 as shown in FIG. The cover 9 is made of heat-resistant material such as aluminum. Thereafter, the tip of the pole 5 and the bushing 2 are melted in the cover 9 to connect them. As shown in FIG. 2, the connection portion upper surface 8 is lower than the outer upper surface 22 of the bushing 2 and is in an uneven shape after connection.
[0011]
Next, as shown in FIG. 2, the flat terminal connection body 6 is placed from above the bushing 2. The connection body 6 has a circular through hole 7 at one end, and the other end is connected to a connection line (not shown). In the state where the connection body 6 is placed on the bushing 2, the lower surface of the connection body 6 abuts on the outer upper surface of the bushing 2, and the through hole 7 of the connection body 6 is disposed on the pole column 5 as can be seen from FIG. 3. Is done. In this state, the connecting body 6 is welded to the connecting portion between the bushing 2 and the pole column 5 with a burner while adding lead from above the through hole 7. Thereafter, the welding surface is flattened to finish the terminal connection method of the present invention.
[0012]
When connecting the bushing 2 and the terminal pole 5, both the cylindrical bodies described in Japanese Patent Application No. 11-85777 filed by the applicant of the present application are used so that the molten lead does not drip into the battery. It may be welded by fitting into the gap.
[0013]
In the present embodiment, the upper surface 8 of the connection portion is made lower than the outer upper surface 22 of the bushing 2, but it is not necessary to make it lower if the diameter of the through hole 7 of the connection body 6 is larger than the width of the upper surface 8 of the connection portion. . However, this embodiment is preferable in order to cope with any connection body 6.
[0014]
As described above, since the outer upper surface 22 of the groove 20 is not melted by the cover 9 when the bushing 2 and the terminal pole 5 are connected, a smooth horizontal plane can be maintained. Then, the lower surface of the terminal connection body 6 is brought into contact with the surface 22 so that the connection between the bushing and the pole column and the connection body can be welded without any gap, and the connection body 6 and the upper surface of the lid 1 can be welded in parallel.
[0015]
Furthermore, since the upper surface of the lid in contact with the bushing 2 is deformed or melted by fire and there is no gap between the bushing 2 and the lid 1, airtightness and liquid tightness are not impaired.
[0016]
【The invention's effect】
As described above, according to the first aspect of the present invention, the connection body can be horizontally disposed on the upper surface of the connection portion between the bushing and the terminal pole, and the connection portion and the connection body can be connected without a gap. Accordingly, it is possible to provide a compact lead battery having excellent terminal connection strength. Moreover, the smoothing operation of the upper surface of the connection part which has been conventionally performed can be eliminated. Furthermore, the airtightness and liquid tightness of the bushing and the lid are not impaired.
[0017]
Further, according to claim 2, it is not necessary to add lead when welding the bushing and the pole column. Moreover, when welding a connection body to these connection parts, since a connection part upper surface does not contact a connection body lower surface, a connection body can be maintained horizontally and it can weld reliably.
