に多くの工夫が払われてきた。Except for some parts, various devices have a desired voltage higher than the voltage of a single battery such as 6V, 12V, 24V, and a plurality of batteries for the purpose of protecting the devices and the batteries. A battery pack is used that is electrically and mechanically connected to and housed in a container. In addition, a lot of efforts have been made to improve the pack container, connect the batteries, insulate each battery, take out terminals, etc. so as to be compatible with devices used as battery packs.

に取りつける工程を簡便なものとすることである。The following three points are important in producing a battery pack having such an arrangement. First, the lead plate 5 that connects the negative electrode 15 of the tenth cell 1j shown in FIG.
Two cells 1b and 1c located along the lead plate 5
Ensure sufficient insulation between If the insulation here is insufficient, there is a risk that the lead plate 5 and the cells 1b and 1c are short-circuited to generate heat or ignite. Lead plate 5 and cell 1
It is necessary to provide sufficient insulation between b and 1c to connect the negative electrode 15 of the cell 1j at the end of the battery group and the lead plate 5. Secondly, in the battery pack, cells 1a to 1b, 1c to 1h, and 1i to suppress the distortion and deformation of the battery group, which is the cause of the swelling and distortion of the case and the variation of the external dimensions.
The electrical connection between each of the battery blocks 1j and between the lead plates 5 and 6 from the terminal 7 and both the positive and negative electrodes of the battery group is fixed in the container. If the battery block is accommodated along the inner shape of the container, it is possible to prevent distortion and deformation of the battery group, and to prevent deformation of the battery pack and variations in external dimensions. Thirdly, in order to reduce the cost of the battery pack, the insulators 8 and 9 are made into one component that can realize a simple mold structure, and the process of attaching the insulator to the battery pack is simplified. .

For insulation from 1c, for example, as shown in FIG.
There is a means for inserting 0 between the lead plate 5 and the cells 1b and 1c after the battery group is constructed, or inserting the molded part 11 having a synthetic resin lead guide bar as shown in FIG. 7 at the same position. . However, these methods require a post-insertion step of the insulators 10 and 11 during the assembly process of the pack, and
It is necessary to fix the insulator in order to achieve sufficient insulation, which increases the number of components of the pack and the assembly process.

能性があるという問題がある。Therefore, in order to eliminate the later insertion of the insulator in the assembly process, a molded part in which the terminals 7 and the lead plate 5 and the insulators 8 and 9 for insulating the cells 1a to 1c are integrated as shown in FIG. 12 are possible. However, with this structure, it becomes impossible to connect the negative electrode of the cell 1b and the positive electrode of 1c after fixing the battery block to the container. As shown in FIG. 9, a lead plate 13 covered with an insulating tube may be considered instead of the lead plate 5 of FIG. 6, but the terminal 7 and the last cell 1j may be used.
Since there is no guide for the lead plate 5 to communicate with
As shown in (A) and (B), the lead plate 13 connected to the negative electrode 15 of the cell 1j due to variations in the assembly work of the pack.
Does not move up or down and the positioning accuracy cannot be obtained, and the spot welded portion 14 rides on the resin tube 16 covering the battery, and the spot welded portion 14 is disengaged from the battery negative electrode 15 and electrically. There is a problem that the connection may not be made enough.
