Abstract

PROBLEM TO BE SOLVED: To facilitate battery connection, and maintenance and to reduce installation manhours by fitting and fixing a bolt head part by the use of a bent metal plate, by welding the metal plate to an electrode post of a battery, and by filling and setting an adhesive in the fitting part and the welded part. SOLUTION: A brass metal plate having a thickness of 2 mm is used as a bent metal plate 1, and a bolt head part of a bolt 2 is bent, and fitted and fixed between the bent parts of the bent metal plate 1. Next, an external connection piece 4 is connected to the outside by fastening it to the bolt 2 with a nut 3 interlaying a washer 5. In this case, after the bolt 2 and the bent metal plate 1 are solder-plated, they are fitted together along the side surface of the bolt head part. The connection of the metal plate 1 to an electrode post 6 is performed by using solder 7, and an epoxy-based adhesive 8 is filled so as to wrap up the fitting part of the bolt head part to the bent metal plate 1, and the soldered part off the bent metal plate 1 to the electrode post 6, and the adhesive is cured.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead storage battery, and more particularly to a terminal structure thereof.

[0002]

2. Description of the Related Art A conventional lead battery terminal having a capacity of 100 AH or less has a structure in which a terminal formed of a metal plate 1 taken out of a battery is fastened together with a connector 4 with bolts 2 and nuts 3 as shown in FIG. ing. Alternatively, as shown in FIG. 4, the bolt 2 is cast into lead or a lead alloy 9 and attached to the battery. In the figure, 5 is a washer for tightening, 6 is a pole of the battery, 7 is a solder for connecting the metal plate 1 and the pole 6, and 8 is filled and hardened so as to wrap around a portion for taking out a terminal from the pole. The adhesive 10 is a lid of the battery case.

[0003] These devices have a structure in which a terminal taken out of a battery and a contact on the device side are directly tightened with bolts and nuts, so that a current can be taken out for a long time without any adverse effect.

[0004]

However, in the case of the terminal having a structure in which the plate-like terminal is tightened with bolts and nuts, the connection with the pole can be easily made by soldering in manufacturing. When connecting the battery terminals to the equipment, the connectors on the equipment side, bolts and nuts, and in some cases, it is necessary to attach and then wash the washer. It was enough.

In a structure in which a bolt described later is cast into lead or a lead alloy, the bolt is fixed to a battery, so that the workability when connecting to an external device is improved, but the strength of the lead alloy itself is improved. Is not enough, it is necessary to perform maintenance work (re-tightening) to tighten the nut every certain period, and it takes more time to manufacture the terminal because of casting operation compared to the above-mentioned machinable terminal at the time of manufacture, and costs increase Since it is necessary to melt both the terminal and the pole when connecting the terminal,
It takes time and welding failures frequently occur.

[0006] As described above, the conventional terminals have disadvantages in production, construction, and maintenance.

[0007]

SUMMARY OF THE INVENTION The lead storage battery of the present invention has been made in order to solve such a problem. In a lead storage battery having a bolted terminal, a bolt head portion is formed by bending a metal plate. The metal plate is welded to the pole of the battery, and the fitting portion and the welded portion are filled and hardened with an adhesive.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the lead storage battery of the present invention, a bolt head portion is mechanically fitted and fixed to a bent metal plate, and one end of the metal plate is welded to a pole of the battery. Fill and cure the weld in the adhesive. By doing so, the manufacturing cost and time can be reduced in manufacturing, the connection time can be reduced when using batteries,
In addition, maintenance can be reduced.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments.

FIG. 1 is a structural view of a terminal portion according to an embodiment of the lead storage battery of the present invention. In FIG. 1, reference numeral 1 denotes a bent metal plate, which is a brass metal plate having a thickness of 2 mm. Numeral 2 denotes a bolt having a bolt head portion fitted and fixed between bent portions of the metal body 1, and is connected to the outside by tightening an external connector 4 to the bolt 2 with a nut 3. 5 is a washer.

In this embodiment, as shown in FIG. 2, the bolt 2 and the bent metal plate 1 are solder-plated, and then the metal plate is placed along the side of the bolt head (here, hexagonal bolt). So that they fit together. Also, the metal plate 1
The connection between the pole and the pole 6 is made by solder 7 and further filled with an epoxy-based adhesive 8 so as to enclose the joint between the bolt head and the bent metal plate and the welded portion with the pole.
Cured. Reference numeral 10 denotes a lid of the battery case.

In this embodiment, brass is used in which a metal plate is plated with solder and is bent along the head of a hexagonal bolt. Is used, and the connector is brought into close contact between the plate body and the nut in such a manner as to be fitted with the bolt, and the material and the shape are not specified.

[0013]

According to the terminal structure of the present invention, the effect of facilitating battery connection and the maintenance after connection can be reduced. Further, the total man-hours from the terminal manufacturing to the battery manufacturing and the terminal connection can be reduced, which leads to the reduction of the man-hours from the manufacturing to the construction and the maintenance.
