Abstract

PURPOSE:To miniaturize a connector by arranging cells in the preset method in a system combining multiple cells and connecting the connector to terminals of both poles. CONSTITUTION:Six cells 2-1 through 2-6 are aligned in two columns and three lines and serially connected. They are arranged so that plus terminals are located on one side of adjacent cells and minus terminals are located on the other side respectively, and the plus terminals and the minus terminals are connected for adjacent cells in sequence with electrode plates 3-1 through 3-5. The plus terminal 4 of the first cell and the minus terminal 5 of the last cell become terminals of both poles of a battery, and they are connected to lead wires 7, 8 of a connector 6 respectively. Since the cells are arranged in this way, the size of the connector 6 can be made small as compared with the case that six cells are arranged in parallel, for example.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a battery constructed by combining a plurality of cells.

(Prior Art) FIG. 6 schematically shows a conventional example of such a battery 101, and there are a plurality of batteries 101 (six in the illustrated example).
It is constructed by combining cells 102-1, 102-2°..., 102-6, and adjacent cells are electrically connected to each other by electrode plates 103... Cells 102-1, 102 (left and right in the figure)
A child terminal 104 and a single terminal 105 were respectively provided at -6.

Therefore, the child terminal 104 and one terminal 1 of the battery 101
05 was connected to the illustrated connector 106, and the wires 107 and 108 connected to the connector 106 were electrically connected to the battery 101.

(Problem to be Solved by the Invention) However, in the conventional battery 101 described above, the child terminal 104. One terminal 105 is the cell 102 at both left and right ends
-1, 102-6, the distance between them becomes long and the connector 106 connected to these + terminals 104 and one terminal 105 becomes large.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a battery in which the connector connected to the positive and negative terminals can be miniaturized by rationally arranging the positive and negative terminals. It is in.

(Means for Solving All) In order to achieve the above object, the present invention provides a battery that is constructed by combining a plurality of cells and has a connector connected to one terminal (+), and a child terminal is connected to one of the adjacent cells. , the other is provided with one terminal, respectively.

(Function) According to the present invention, since the child terminal and one terminal of the battery are arranged in adjacent cells, the two are arranged close to each other, and the connector connected thereto can be miniaturized.

(Example) An example of the present invention will be described below based on the accompanying drawings.

Fig. 1 is a schematic plan view showing the terminal arrangement of the battery according to the present invention, Fig. 2 is a perspective view showing the state before the connector is attached to the battery, and Fig. 3 is the state where the connector is attached to the battery. FIG. 4 is a perspective view showing the terminal structure, and FIG. 5 is a perspective view showing the state in which the battery is used vertically.

As shown in FIG. 1, the battery l according to the present invention has six
Cell 2-1.2-2. ..., 2-6 are integrated into 2 rows and 3 rows, and cells 2-1.2
-2. ..., adjacent cells 2-6, i.e. cells 2-1 and 2-2, cells 2-2 and 2-3, cells 2-3 and 2
-4, cells 2-4 and 2-5, cells 2-5 and 2-6 are electrically connected to each other by electrode plates 3-1.3-2.3-3.3-4.3-5, respectively. These cells 2-1
．． 2-2. ..., 2-6 are connected in series. Therefore, in Hauteri-1.

The current flows from the child terminal 4 side to the cells 2-1, 2-2. ...2-
6 flows toward one terminal 5 side in the order of 6.

Further, among the cells 2-1 and 2-6 adjacent to each other, one cell 2-1 is provided with a child terminal 4, and the other cell 2-6 is provided with a terminal 5. A connector 6 is connected to the child terminal 4 and one terminal 5, and the wires 7.8 connected to the connector 6 are electrically connected to the child terminal 4 and one terminal 5 of the battery 1, respectively.

The specific structure of the battery l is shown in FIG. 2, and a recess (terminal storage part) la into which the connector 6 is to be attached is formed in a part of the short side of the battery l. The flat child terminals 4 and one terminal 5 are arranged in the recessed portion 1a in the vertical direction. still,
In FIG. 2, 15.15 is a partition wall for preventing current leakage.

However, the + terminal 4 and the one terminal 5 are actually the fourth terminal.
As shown in the figure, it is assembled into a block 9 integrally molded from resin. That is, the child terminal 4 and one terminal 5 are connected to the block 9
block 9 together with the electrode plate connection part 10.10 when integrally molded.
be incorporated into.

Therefore, the distance (pitch) between the child terminals 4 and one terminal 5 is maintained with high accuracy, and the connector 6 is reliably attached to these. In addition, the plate connection portion 10.10 and the child terminal 4'
The cells 2-1, 2-2. ...2-6 (111 pole plate 3-1.
After connecting 3-5 to the plate connection part 10.10 via a sorting wire etc., the block 9 is assembled into the casing of the battery l and this is molded, etc., and the child terminal 4 and one terminal 5 are formed as shown in FIG. arranged as shown.

Then, the connector 6 is connected to the battery l shown in FIG.
When the connector 6 is fitted into the recess 1a from the direction of the arrow shown in the figure, the connector 6 is attached to the recess 1a so as to constitute a part of the main body of the battery 1, as shown in FIG.

By the way, as shown in FIG. 3, connection parts 12.13 are provided in the middle of the wire 7.8 leading out from the harness 11, and these connection parts 12.13 can be removed to connect meters and equipment. If you connect it, you can measure the charging current and
charging backup is possible.

Further, as shown in FIG. 3, a water drain hole 14 is provided in a part of the side wall of the kitchen terry 1 and communicates with the chamber partitioned by the partition wall 15.15 of the fourth part 1a. As shown in the figure, even if the secondary terminal 4 and the terminal 5 are exposed to water when the battery 1 is placed vertically and used, the water will be drained out through the wood cutting hole 14, so water will not accumulate in the recess 1a. .

(Effects of the Invention) As is clear from the above explanation, according to the present invention, since the child terminals and one terminal of the battery are arranged in adjacent cells,
Both are placed close to each other, and the effect is that the connectors connected to them can be miniaturized.
