Abstract

PURPOSE:To eliminate double injection molding by securing liquidtightness in an intercell contact part while a battery jar and a cap are thermally welded and to fit in the intercell contact part with no force and smoothly by providing a sleeve with a slit. CONSTITUTION:Firstly a group of pole plates 9 and 9', whereof both pole pillars 11 and 11' are connected through an intercell part 12, is made and accomodated in a battery jar 1. Next, the top end of the battery jar 1 and the bottom face of a cap 5 as well as the inside of a sleeve 6 are thermally welded by means of a hot plate, then the battery jar 1 and the cap 5 are pressed each other while removing said hot plate for fitting the intercell contact part 12 in a sleeve 6 thus to obtain a storage battery while securing liquidtightness of said part. When the intercell contact part 12 is fitted in the sleeve 6, the welded and softened inside wall of said sleeve 6 adheres to the outside of the intercell contact part 12, while surplus resin flows into a slit 7 to more surely maintain liquidtightness of the intercell part.

層確実に保持する。Next, to explain the manufacturing of the illustrated storage tank, first, the electrode plate groups 9 and 91 in which the pole columns 11 and 11' are connected to each other by the inter-cell connection part 12 are manufactured, and this is shown in FIG. As shown in FIG. 4, it is housed in a container 1 (see FIG. 4). Next, heat plate (
After heating and melting the upper end of the battery case 1, the lower surface of the lid 5 shown in FIGS. When pressed, the first
As shown in the figure and FIG.
A storage battery is obtained in which the liquid-tightness of the core portion is ensured. When the inter-cell connection part 12 is fitted into the sleeve 6 as described above, the melted and softened inner wall of the sleeve 6 comes into close contact with the outer surface of the inter-cell connection part 12, and excess resin flows into the slit 7 to connect the cells. Maintains liquid tightness even more reliably.

が一段と向上する。Also, in the above embodiment, the electrode group?・Although an example was shown in which the inter-cell connection portion 12 is formed before housing the cell 9′ in the battery case 1,
In some cases'! After the five plate groups 9 and 91 are housed in the battery case, the heads of the bipolar columns 11 and 11' may be melted in a bath to form the inter-cell connection part 12. The structure is configured as shown in Figure 4, and it is possible to heat the battery case and lid while simultaneously maintaining the liquid-tightness of the connection between the cells, making it possible to omit the conventional double injection molding, and improving the productivity of the storage battery. This is a significant improvement, and since the sleeve is provided with a slit, fitting and inserting the inter-cell connection portion can be done smoothly and effortlessly. In particular, when the structure is such that the groove provided on the side end face of the nine-slit slit shown in the example is fitted with the protrusion provided near the notch, the inter-cell connection portion is more firmly fixed, and the storage battery The resistance to 1 dragon is further improved.
