Description

[Detailed description of the invention] This invention relates to the improvement of storage batteries, in which the spacer and separator of a lead-acid battery floats up from the electrode group due to external vibrations, force due to internal gutting, etc., or its own buoyancy. The purpose is to prevent it from slipping or slipping.

In general, in a lead-acid battery, a separator inserted between the electrode plates provided to form an electrode group and a spacer for supporting the electrode group are affected by the vibration of the storage battery or the force caused by gutting inside the battery. There is a risk that the battery may float or become detached from the electrode plate due to its own buoyancy, which impairs its performance as a storage battery.

Conventionally, in order to prevent these separators or spacers from floating or coming off, they were tightly pressed into the battery case of the electrode plate group formed together with the electrode plates.

Therefore, the thickness of the electrode plate group is extremely problematic, and if there is even a slight error in the thickness dimension, it may become loose or cannot be inserted into the battery case.

Therefore, it is difficult to adjust the thickness of the electrode plate group, which significantly reduces workability and requires strict thickness dimensions of the electrode plate group.

The present invention has been made as a result of intensive research aimed at improving these drawbacks, and has resulted in the discovery of a storage battery in which there is no risk of the separators and spacers floating up in the electrode plate group.

That is, in the present invention, a pole plate group 6 is provided with a spacer 9 having a protrusion 10 on both ends thereof, and a pole plate group abutting plate is attached to the horizontal portion of the U-shaped frame 2 consisting of a horizontal portion 3 and a leg portion 4. 5, the legs 4 engage with the protrusion 10, the electrode plate group contact plate 5 abuts the upper end of the electrode plate group 6, and the frame It is characterized in that the upper edge of the horizontal portion 3 of the body 2 is in contact with or close to the lower surface of the pole post 11 of the electrode plate group 6 or the strap.

An example of the present invention will be explained in detail based on the drawings.

As shown in FIGS. 1 and 2, a notch is provided in the horizontal portion 3 of the U-shaped frame 2 made of polyvinyl chloride or the like, and an electrode plate made of polyvinyl chloride or the like is parallel to the horizontal portion. The group contact plate 5 is attached to obtain the U-shaped support 1.

Note that 4 is a leg portion of the frame body. Then, this support 1 is
It is attached to the electrode plate group 6 as shown in the figure.

The structure of this electrode plate group 6 is that separators 8, 8 are inserted between the electrode plates 7, 7, and a spacer 9 is provided on the outer surface of the separator 9. The spacer 9 is attached to the inner wall of the battery case (not shown). ) is attached with a protrusion 10 for holding down the electrode plate group, which is made of a hollow polyvinyl chloride pipe or the like, in order to bring the electrode plate group into close contact with the electrode plate group.

The plate group 6 is inserted between the legs 4 of the support 1, and the horizontal part 3 is brought into contact with the pole post 11 so that it can be fitted between the plate group 6 and the pole post 11, and is supported. The electrode plate group abutment plate 5 of the tool 1 presses the electrode plate group 6, and the frame vertical leg portion 4 is engaged with the electrode plate group holding protrusion 10.

In this way, in the present invention, the legs of the U-shaped support attached to the upper end of the electrode group are engaged with the protrusions, so that the strong pressing force on the electrode group by the electrode group abutment plate is eliminated. At the same time, the upper edge of the support is brought into contact with or close to the bottom surface of the pole pole or strap, so that the support does not separate from the electrode group, prevents the movement of the electrode group, and prevents the electrode group from moving. And floating of the spacer can be sufficiently prevented.

In addition, even if a gap is created between the frame and the electrode plate group when attaching the electrode plate group to the support, there is no need to worry because the electrode plate group is pressed from all sides as described above. .

Therefore, the thickness dimension of the electrode plate group does not have to be so strict, and workability is significantly improved, which has remarkable effects.
