Abstract

PURPOSE:To retain electrical connection between batteries and to avoid the disconnection of battery pack output voltage even if outside force is applied by electrically connecting batteries with a conductive wire. CONSTITUTION:Batteries 22, 24 are electrically connected with a conductive wire 26. Insulating spacers 28, 30 made of rigid material are placed between the batteries 22, 24 to ensure a constant distance. The batteries 22, 24, the conductive wire 26, and the spacers 28, 30 are accommodated in a heat- shrinkable outer tube 32 made of vinyl chloride, and heat is applied to the outer tube 32 to shrink it for fixing them. Just before the use of the batteries, a traction string is pulled to remove sealing plugs 8, 8', then the batteries are put into water. Water enters the batteries and voltage is produced. Even if batteries are slipped by the outside force, the conductive wire 26 absorbs the slippage and damage to the connecting parts of the conductive wire 26 with batteries 22, 24 are avoided and disconnection of output voltage is also avoided.

In conventional battery packs, rigid conductive plates are spot welded to the ends of the cells to firmly secure them together. FIG. 4 is an exploded view of a conventional battery-to-battery connection structure, and FIG. 5 is a sectional view of the connected state. 10° 12 is a battery, and a nickel plate 14 electrically connects the batteries 10 and 12. The nickel plate 14 is bent into a U-shape, and a slit 16 is formed on the negative side of the nickel plate 14 to accommodate the protrusion of the positive electrode of the battery 12.

One end of the U-shaped nickel plate 14 is spot welded to the battery 10, and the other end is spot welded to the battery 12. The entirety of the plurality of batteries electrically connected in this way is housed in a shrinkable vinyl chloride tube, and the tube is shrunk by heat, for example, to be integrated. There is also a configuration in which the entirety of a plurality of electrically connected batteries is molded with epoxy resin and integrated.

[Problems to be Solved by the Invention] However, in the conventional example where the battery pack is integrated using a shrinkable tube or mold, if the external force applied to the battery pack is small, it is absorbed by the tube or mold. If an external force exceeding a certain level is applied, most of the force will be applied to the connecting members between the batteries, especially the spot welded parts, and there is a risk of breakage. Such a situation may occur, for example, if the portable device is dropped or if the battery pack is strongly pressed with a hand or finger.

2.24, and a conductive wire 2 is connected between the batteries 22.24.
Electrical connection is made by 6. 28.30 is battery 22.2
This is a spacer made of a strong material to maintain a constant distance between the two. Spacers 28, 30 are made of the insulating material described above. The batteries 22, 24, the conductive wires 26, and the spacers 28, 30 are housed in a heat-shrinkable jacket tube 32 made of vinyl chloride, and then the jacket tube 32
Heat is applied to shrink the parts, thereby making the whole piece into one piece. In addition, it should be noted that in FIG. 1, each member is drawn at some intervals so that their positional relationship can be clearly seen. Due to the shrinkable tube 32, the axial displacement of the cell 22.24 is minimal, if any, and the lateral displacement perpendicular to the axis is also small, depending on the strength of the jacket tube 32.

The manufacturing procedure will be briefly explained. First, a conductive wire 26 of an appropriate length is prepared. Pads (metal plates) are placed at both ends of this conductive wire 26 for spot welding with the battery ends.
34, 36 are fixed by soldering or the like, and the pads 34, 36 are spot welded to the ends of the batteries 22, 24. The total length of the conductive wire 26 is a length that is a little longer than the distance between the batteries due to the spacer 28.30, and is long enough to facilitate spot welding of the pad 34.36 to the battery end. good. If the distance between the batteries is too long compared to the distance between the batteries, the batteries may

A spacer 28.30 is fitted between the cells 22.24 thus electrically connected by conductive wires 26 and threaded through the jacket tube 32. Then, a predetermined amount of heat is applied. This heat causes the jacket tube 32 to contract, causing the battery 22.24 to shrink.

In the integrated state shown in FIG. 1, the contraction force of the jacket tube 32 exerts a force on the cells 22, 24 in a direction toward each other. Therefore, basically, battery 2
2.24 in its axial direction can be resisted to a considerable extent, depending on the tensile force of the jacket tube 32.

Of course, even if the batteries 22 and 24 actually move apart from each other in the axial direction due to an external force, if the amount of movement is within the length range of the conductive wire 26, the external force will be applied to the conductive wire 22.

Also, when an external force is applied in a direction perpendicular to the axis of the batteries 22, 24, the batteries 22, 24 will shift laterally relative to each other. This can occur with relatively small external forces.

Basically, the longer the conductive wire that connects the batteries, the more resistant they will be to misalignment of each battery. In accordance with this idea, in FIG. 6, even when five batteries are connected in series, electrical connections are made between distant batteries. That is, ten poles of the first battery 40 and one pole of the third battery 44, ten poles of the second battery 42 and one pole of the first battery 40, ten poles of the fourth battery 46 and one pole of the fifth battery 44. battery 4
Conductive wires 50, 52, 54, 56 connect one pole of 8, ten poles of the fifth battery 48, and one pole of the second battery 42, respectively.
The ten poles of the third battery and one pole of the fourth battery are used as voltage output terminals of the illustrated battery bag. In this case, there is a gap between adjacent batteries that are not electrically connected.
An insulator such as insulating paper is inserted to prevent the conductive wire pads from electrically connecting or touching each other.

Although an example in which the components are integrated using a heat-shrinkable tube has been described, it is of course applicable to molding with resin or housing them in a somewhat rigid plastic tube. . It can also be applied to cases where each battery is provided with a frame such as a case or a frame, or a cylindrical body such as a plastic tube, for precisely arranging each battery. This is because even if such a frame is used, there will be some gaps due to the intersection of the outer shapes of the batteries, and these gaps will cause the batteries to become misaligned when external forces are applied.

[Effects of the Invention] As can be easily understood from the above description, according to the present invention, the electrical connection between the batteries can be maintained even by external force, and the battery pack output voltage will not be interrupted. Therefore, there is no possibility that the output voltage is momentarily or permanently interrupted due to a poor connection between the batteries, making it possible to further reduce the weight and size of portable devices that use battery packs as a power source.

This also causes the battery pack's lifespan to depend solely on the unique lifespan of each battery used, substantially increasing the lifespan of the battery pack.
