Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the manufacturing method of lead-acid batteries, and in particular, in a so-called monoblock storage battery in which a plurality of cell cells are integrally formed, a partition wall of a haze tank is provided between adjacent electrode plate groups. The purpose is to improve the electrode plate group connector when connecting through the through holes.

In conventional so-called monoblock storage batteries, unit battery tank 1
In order to connect adjacent electrode plates housed in a group of electrodes, as shown in FIGS. 1 and 2, a male connector made of lead alloy with a protrusion 3 extending from the connection band 2 is used. One pole with 4,
For example, from the anode plate group 5 and the connection band 6, the connection hole 7
The other one of the electrodes, for example, the cathode plate group 9, provided with a female connector 8 made of lead alloy having a hole therein, is connected to the unit battery cells 1 adjacent to each other via a partition wall 11 having a through hole 10 formed therein. The protruding part 3 of the male connector 4 is inserted into the through hole 1, and the female connector 8 of the adjacent cathode plate group 9 is inserted into the connecting hole 7 of the negative electrode plate group 9. Insertion and connection hole 7
A method is adopted in which the male connector 4 and the female connector 8 are connected by fusing them together in the space 12 and flowing molten lead or the like. However, when the protrusion 3 inserted into the connection hole 7 of the female connector 8 is fused to the female connector 8 in the connection hole 7, and molten lead is to be introduced. As shown in Fig. 2, the gas burner 13 must be inserted into the unit battery tank 1 with the battery case turned upside down, but if the inside of the unit battery tank 1 is narrow, it is necessary to insert a There is no space for inserting the gas burner 13 into the unit battery tank 1 with the mold 14 attached, and therefore, the post-melting work is often difficult. In view of the above-mentioned drawbacks, the present invention solves the problem of welding a male connector and a female connector by melting and fixing both female and male connectors without inverting the battery case. A concave portion with a trough-like cross section is formed in the child.

That is, the upper part of the columnar female connector has a trough-like cross section so that the inner cross-sectional shape of the protrusion of the male connector inserted into the through hole of the partition wall can be placed in a lying state. A concave part is formed, and by melting and fixing the protrusion layered in the concave part and the upper part of the female connector with a flame such as a gas burner, both the female and male connectors can be attached to the partition wall of the dragon tank. The female and male connectors are connected through the connectors, and the female and male connectors are pressed toward the partition wall from both ends of each connector, so that the lip portions of the female and male connectors are pressed against the partition wall, thereby completely draining the liquid between adjacent cells. It is intended to connect in a disconnected state. Next, one embodiment of the present invention will be described. A female connector 8' is installed in the cathode side connecting band 6' that groups the cathode plate groups 9' in a columnar shape, and at its upper part, the anodes housed in the adjacent unit battery cells 1' are connected to each other. Board group 5
The protrusion 3' of the male connector 4' that stands on the anode-side connection band 2' with clusters of
A concave portion 15 with a trough-like cross section is cut into the plate to be inserted into the plate and placed on top of the plate.

In one embodiment of the present invention, as shown in FIG. 4, a welding die 14' is opened at the upper part of the female connector 8'.
is iron-fitted across the male connector 4' and the female connector 8', and the flame of the gas burner 13' is emitted from above the female connector 8' to project the protruding portion 3'. and concave portion 15
By melting the wall surface of the male connector 4 and the female connector 8',
are connected via the bulkhead 11', and then the male connector 4'
When the female connector 8' is pressed toward the partition wall 11' from both ends thereof, the ribs 16' protruding from the male connector 4' and the female connector 8' are crimped to the partition wall 11'. The cathode plate group 9 and the anode plate group 5' which are interlocked and adjacent to each other in the lightning tank are as follows:
Connected in a liquid-tight manner. As mentioned above, the present invention provides female,
When welding male and female connections, there is no need to invert the battery case housing the electrode plate group, and even if the inside of the dew tank cell is narrow, it is convenient because a welding gas burner etc. can be easily inserted and the welding work can be performed. This method has great practical value, as it simplifies the manufacturing process of storage batteries and provides a completely liquid-tight electrode plate group connection.
