[Problems to be solved by the device]

 The battery pack of this structure has a feature that five batteries 1 are connected by a terminal fixing base 4 to form a battery block 2 and a plurality of batteries 1 can be housed in a case 3 as one battery block 2. However, the battery having this structure has a drawback that it is difficult to store the battery block so as not to move in the case. This is because it is difficult to accurately match the outer shape of the connected battery blocks with the inner shape of the case. The outer shape of one battery can be controlled relatively accurately in the manufacturing process. However, it is extremely difficult to improve the dimensional accuracy of the battery block in which a plurality of batteries are connected to the terminal fixing base 4. This is because the outer dimensions of the battery block easily change depending on the connected state of the batteries. When multiple batteries are tightly connected, the battery block becomes smaller, and when they are loosely connected, they become larger.

Further, the battery connected to the terminal fixing base and housed in the case is designed to be a little smaller because the battery cannot be housed in the case if the battery block is too large. As a result, there is a gap between the battery block and the case, which makes it impossible to store the battery without rattling.

Further, the battery 1 shown in FIG. 1 has the connection window 7 opened to expose the connection terminals 6 of the terminal fixing base 4 to the outside of the case 3, so that the battery block 2 is housed in the case 3. The direction to do is specified. If the storage direction is wrong, the connection terminal 6 of the terminal fixing base 4 will be displaced because the position of the connection window 7 will be displaced, resulting in a defective product.

The present invention was developed with the object of solving this drawback. An important object of the present invention is that the battery can be stored in the case without rattling, and the storage position of the battery can be changed if necessary. It is to provide a battery pack that can be specified.

[0007]

[Means for Solving the Problems]

 The battery pack of the present invention has the following configuration in order to achieve the above object. In the battery pack, a plurality of batteries 1 are connected to a terminal fixing base 4 to form a battery block 2. The battery block 2 is housed in the case 3. The connection terminal 6 of the terminal fixing base 4 is exposed to the outside of the case 3. On the opposing surfaces of the terminal fixing base 4 and the case 3, a convex portion 8 is provided on one side and a concave portion 9 into which the convex portion 8 is fitted is provided on the other side.

Preferably, the convex portion 8 is provided on the case 3 and the concave portion 9 is provided on the terminal fixing base 4, but it is also possible to provide the convex portion on the terminal fixing base and the concave portion on the case. By inserting the convex portion into the concave portion, the positions of the terminal fixing base 4 and the case 3 are specified, and the plurality of batteries 1 are housed in the case 3 via the terminal fixing base 4.

[0009]

[Action]

 The battery pack of this invention is provided with a convex portion 8 and a concave portion 9 on the surface facing the case 3 and the terminal fixing base 4 connecting the battery 1. By inserting the convex portion 8 into the concave portion 9, the battery 1 is fixed at a fixed position of the case 3 via the terminal fixing base 4. Therefore, the battery 1 housed in the case 3 is housed inside without being dull. In addition to fixing the connection terminal 6, the terminal fixing base 4 prevents the rattling of the battery 1. Therefore, the battery can be fixed in the case without increasing the cost without using special parts.
