DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shunt wire for electrode connection, which is used to electrically connect secondary batteries such as lead storage batteries, alkaline storage batteries, solar cells and the like mainly used in electric vehicles and the like. It is about.

[0002]

2. Description of the Related Art Conventionally, shunt leads having high mechanical strength are often used to electrically connect storage batteries of this type to one another. This shunt lead wire is formed by braiding a tin-plated copper wire, both ends of which are inserted into a flat cylindrical copper sleeve and are compression-integrated into a flat plate, and are inserted into through holes formed in the flat copper sleeve. A pin-shaped electrode of a storage battery is inserted and used.

[0003]

The electrodes of this type of storage battery are usually made of aluminum or copper or brass, and the copper material of the copper sleeve at the end of the shunt lead wire and the aluminum or copper or brass of the electrodes are used. Used in direct contact with the material. However, if copper and aluminum or copper are used for a long time in contact with each other, corrosion may occur due to a potential difference or other causes, and there may be a problem such as a decrease in conductivity efficiency or a heat generation due to a poor contact. Needed frequent inspections.

Accordingly, the present invention uses a shunt lead having copper sleeves at both ends,
The main purpose is to provide an electrode connection shunt wire in which an electrode made of aluminum or the like of a storage battery is prevented from directly contacting the inner surface of a hole of a copper sleeve, thereby preventing corrosion at a connection portion between the electrode and the copper sleeve. It is the purpose.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the shunt wire for electrode connection according to the present invention, both ends of a shunt lead wire 1 formed by bundling a copper wire into a band shape are inserted into a copper sleeve 2 having a flat cylindrical shape, and are compressed and integrated into a flat plate shape. The compressed flat copper sleeve 2 is provided with a through hole 3 for connecting an electrode, and the hole 3 is provided with a disc-shaped flange portion 4.
This is configured by inserting a stainless bush 4 having a.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of a shunt wire for electric wire connection according to the present invention, and reference numeral 1 denotes a shunt lead wire. The shunt lead wire 1 is conventionally known, and is formed in a band shape by bundling a large number of tin-plated copper wires into a plain weave. Some copper wires are not tin-plated.

Both ends of the shunt lead wire 1 are inserted into a flat cylindrical copper sleeve 2 and are compression-integrated into a flat plate shape. Further, a hole 3 for electrode connection is provided vertically through the copper sleeve 2 compressed in a flat plate shape, and a cylindrical stainless bush 4 is inserted into the hole 3. The bush 4 has a large-diameter flange portion 4a at the lower opening edge.
Which covers the inner surface of the hole 3 and the lower edge of the opening.

As shown in FIG. 3, the shunt wire constructed as described above is fitted with the electrode 8 of the storage battery 7 on the left side of the figure into the hole 3 of one sleeve 2 and connected to the hole 3 of the other sleeve 2. It is used to fit the electrode 8 of the right storage battery 7 and electrically connect the left and right storage batteries 7. in this case,
Since the inner surface of the hole 3 of the copper sleeve 2 and the opening edge of the lower end are covered with the stainless bush 4, the aluminum electrodes 8, 8 are prevented from directly contacting the copper sleeve 2, thereby preventing corrosion. Can be suppressed.

The copper sleeves 2, 2 on the left and right sides of the shunt wire shown in the above embodiment are provided with cord connection holes 5, 5 penetrating vertically, and screw holes are provided in the holes 5, 5. Are press-fitted. The self-fastener 6 has a through screw hole 6a and serves to screw-connect the terminal 9a of the cord 9 for external connection as shown in FIG. Note that the cord connection hole 5 does not necessarily need to be provided in the left and right sleeves 2 and 2, for example, is formed only in one of the sleeves 2 and is placed at one end of the storage battery group connected to each other. The battery may be attached to the anode of the battery and the cathode of the battery located at the other end. Therefore, the shunt sleeves 2 and 2 for connecting the intermediate storage batteries can omit the above-described cord connection holes 5 and 5.

In the present invention, the left and right sleeves 2, 2
Needless to say, the size of the middle shunt lead wire 1 is changed according to the size and capacity of the storage battery used.
For example, as shown in FIG. 5, the intermediate shunt lead wire 1 may be formed with a shorter overall length. In this embodiment, a hole 5 for connecting a cord is formed only in one sleeve 2. Also, as shown in FIG. 6, the shunt lead 1 is
Many copper wires are formed in a plain weave shape in a state where many copper wires are aligned.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to only the structures of the embodiments, but has the structural requirements and achieves the above object. However, as long as it has the following effects, it can be appropriately modified and implemented.

[0012]

As described above, in the shunt wire of the present invention, since the inner surface of the hole of the copper sleeve and the outer peripheral surface of one of the holes are covered with the bush with the stainless steel flange, the aluminum to be fitted into the hole is used. The electrode made of copper or the electrode made of copper or brass is prevented from directly contacting the copper sleeve, and the occurrence of corrosion can be suppressed beforehand, thereby reducing the conduction efficiency during use and generating heat due to poor contact. There is a remarkable effect that a trouble can be prevented and the number of complicated inspections can be reduced.
