No. 0 secondary batteries 2j are arranged side by side with their outer peripheral surfaces in contact with each other so that the anodes of the secondary batteries 2j are adjacent to each other.

Then, the first to fifth secondary batteries 2a to
2e and the sixth to tenth secondary batteries 2f to 2j are stacked with the gap plate 5 in between.

In such a state, one substantially rectangular anode plate 6 is, for example, so-called spot welded to the anode of the first secondary battery 2a and the anode of the sixth secondary battery 2f. Further, one substantially rectangular cathode plate 7 is spot-welded to the cathode of the fifth secondary battery 2e and the cathode of the tenth secondary battery 2j. Further, the cathode of the second secondary battery 2b, the anode of the third secondary battery 2c, the cathode of the seventh secondary battery 2g, and the eighth secondary battery 2h.

The H-shaped connecting plate is spot-welded, and the cathode of the third secondary battery 2c, the anode of the fourth secondary battery 2d, the eighth
An unillustrated H-shaped connection plate is spot-welded to the cathode of the secondary battery 2h and the anode of the ninth secondary battery 2i.

That is, the above-mentioned first to tenth secondary batteries 2

The secondary battery 2 is mounted on the electronic circuit board 3.

A display unit 11 including the light emitting diodes 11a to 11e, an anode connector 12 serving as an anode terminal of the electronic circuit, and a cathode connector 13 serving as a cathode terminal of the electronic circuit are provided.

The height of the anode connector 12 and the height of the cathode connector 13 are the same as the height of the electronic circuit board 3, respectively. The upper right corner of FIG. It is provided at the lower left corner in the figure by soldering by so-called dipping, for example. In addition, as shown in FIGS. 2A and 2B, the anode plate 6 and the cathode plate 7 can be inserted into the anode connector 12 and the cathode connector 13, respectively. An anode plate insertion hole 30 and a cathode plate insertion hole 31 which are slightly larger than the above are provided. In addition, the anode plate insertion hole 3
0 and the cathode plate insertion hole 31 are provided with leaf springs 31 so as to obliquely close the anode plate insertion hole 30 or the cathode plate insertion hole 31.

Further, the anode connector 12 and the cathode connector 13 are provided with an anode terminal pin 32 or a cathode terminal pin 33 for connecting to an unillustrated anode line and cathode line of the electronic circuit board 3. ing.

[0030] Normally, the connector is difficult to carry a large current and the contact resistance is apt to increase, and therefore, like the battery pack, for example, it is several amperes in a steady state and several ten amperes in a short circuit (short circuit). Although it is difficult to use it for a device through which an electric current flows, the anode connector 12 and the cathode connector 13 are configured to press the anode plate 6 or the cathode plate 7 by the leaf spring 31 to sandwich them. Since the contact area between the leaf spring 31 and the anode plate 6 or the cathode plate 7 is small, the contact resistance between the anode connector 12 and the cathode connector 13 can be reduced, and a large current can easily flow. ing.

The height of the upper case 1 is slightly higher than the height when the secondary battery 2 is connected to the electronic circuit board 3, and the electronic circuit to which the secondary battery 2 is connected. The size is such that the substrate 3 can be stored. In addition, when the secondary battery 2 and the electronic circuit board 3 are housed, the first to fifth units are provided on the electronic circuit board.
The first to fifth display holes 15a to 15e are provided so that the surfaces of the light emitting diodes 11a to 11e are exposed, and the switch hole 16 is provided so that the remaining amount detection switch 10 is exposed. ing.

Is provided with a cathode contact plate hole 20 in which a substantially rectangular cathode contact plate 18 connected to the cathode terminal is provided. The anode contact plate hole 19 and the cathode contact plate hole 20 are respectively the above-mentioned holes. It has a substantially elliptical shape slightly smaller than the anode contact plate 17 and the cathode contact plate 18.

When assembling such a battery pack, first, as shown in FIGS. 2A and 2B, the anode connector 12 and the cathode connector 12 of the electronic circuit board 3 on which the electronic circuit is provided. The anode plate 6 and the cathode plate 7 which are spot-welded to the secondary battery 2 are inserted into the respective batteries 13. In this case, the anode plate 6 and the cathode plate 7 press the leaf spring 31 provided on the anode connector 12 and the cathode connector 13 in the direction of arrow A shown in FIG. And the cathode connector 13, respectively. When the anode plate 6 and the cathode plate 7 are inserted into the anode connector 12 and the cathode connector 13, respectively,
The leaf spring 31 pushes back the anode plate 6 or the cathode plate 7 in the direction of the arrow B shown in FIG. To pinch.

Therefore, the anode plate 6 or the cathode plate 7 is
The positive electrode connector 12 and the negative electrode connector 13 are securely sandwiched, respectively, and the secondary battery 2 and the electronic circuit board 3 can be reliably connected without soldering by hand. . Therefore, it is possible to simplify the assembly process of the battery pack by omitting the troublesome work such as the manual soldering.

Further, since the secondary battery 2 and the electronic circuit board 3 can be reliably connected to each other, it is not necessary to perform soldering by so-called dipping or reflow, and the secondary battery can be formed by soldering by the dipping or reflow. The battery 2 can be prevented from being damaged, and so-called spot welding need not be performed, and the electronic circuit can be prevented from being damaged by the spot welding.

Then, when the product inspection of the battery pack is performed and a defect is found in the secondary battery 2 or the electronic circuit board 3, the secondary battery 2 and the electronic circuit board 3 are detected.
Since the connector 12 and the connector 13 are connected without soldering, the secondary battery 2 and the electronic circuit board 3 can be easily separated and the product inspection can be facilitated. Moreover, repairs can be performed easily.

When the connection between the secondary battery 2 and the electronic circuit board 3 is completed in this way, the secondary battery 2 and the electronic circuit board 3 are then housed in the upper case 1. At this time, the surfaces of the first to fifth light emitting diodes 11a to 11e and the remaining amount detection switch 10 are exposed from the first to fifth display holes 15a to 15e and the switch hole 16, respectively. The secondary battery 2 and the electronic circuit board 3 are housed in the upper case 1.

Next, the anode contact plate 17 connected to the anode terminal of the electronic circuit board 3 and the cathode contact plate 18 connected to the cathode terminal of the electronic circuit board 3 are respectively attached from the back side of the lower case 19. The holes 19 for the anode contact plate and the holes 20 for the cathode contact plate are provided so as to cover the holes. Then, in this state, the upper case 1 and the lower case 4 are put together and adhered to complete the assembly of the battery pack.

The anode connector and the cathode connector provided on the electronic circuit board 3 are, for example, as shown in FIG.
It can also be configured as shown in (b). That is, FIG.
The anode connector 35 and the cathode connector 36 shown in (a) and (b) do not have the leaf springs 31 of the anode connector 12 and the cathode connector 13 shown in FIG. Therefore, as shown in FIG. 3A, the tip portion 37a of the anode plate 37 and the cathode plate 3 provided in the secondary battery 2 are provided.
The tip end portion 38a of No. 8 is bent in a V shape. When inserting into the anode connector 35 and the cathode connector 36, the tip portion 37a and the tip portion 38a are bent in the direction of arrow C in FIG. It is inserted into the insertion hole 40. As a result, the tip portion 37a and the tip portion 38a are separated from each other by the arrow C.
Since the tip portion 37a and the tip portion 38a press the anode plate insertion hole 39 and the cathode plate insertion hole 40 from the inner side, the tip portion 37a and the tip portion 38a try to spread in the direction of the arrow D in FIG. The anode plate 37 and the cathode plate 38 are securely held by the anode connector 35 and the cathode connector 36. Therefore, the secondary battery 2 and the electronic circuit board 3 can be reliably connected, and the same effect as that of the above-described embodiment can be obtained.

The anode connector and the cathode connector provided on the electronic circuit board 3 are, for example, as shown in FIG.
It can also be configured as shown in (b). That is, FIG.
The anode connector 42 and the cathode connector 43 shown in (a) and (b) include an anode plate insertion hole 44 and a cathode insertion hole 45.
Has a substantially cylindrical shape. On the other hand, the anode plate 46 and the cathode plate 47 provided in the secondary battery 2 have so-called banana chip-shaped tip portions 46a and 47a as shown in FIGS. 4 (a) and 4 (b), for example. ing.

When connecting the electronic circuit board 3 and the secondary battery 2 to each other, as shown in FIG. 4B, the anode plate 4 is connected.
6 and banana chip-shaped tip portions 46a, 4 of the cathode plate 47
7a is inserted into the anode plate insertion hole 44 and the cathode insertion hole 45. Thereby, the banana chip-shaped tip portion 46
Since the a and 47a are about to expand, the positive electrode plate insertion hole 44 and the negative electrode plate insertion hole 45 are pressed from the inside, so that the positive electrode plate 42 and the negative electrode connector 43 ensure the positive electrode plate 46 and the negative electrode plate 47. It is pinched. For this reason,
The secondary battery 2 and the electronic circuit board 3 can be reliably connected, and the same effect as that of the above-described embodiment can be obtained.

Finally, the technical idea of the present invention is that the electronic circuit board is provided with a connector terminal, and the connector terminal elastically sandwiches the anode plate and the cathode plate connected to the secondary battery to assemble them. Is to simplify the above. Therefore, in the above description of the embodiment, the anode connector 12 is used.
Although a total of two connectors including the cathode connector 13 and the cathode connector 13 are provided, any number of connectors may be provided as necessary.
In addition, the anode connectors 12, 3 shown in FIGS.
The shapes and structures of the reference numerals 5, 42, the cathode connectors 13, 36, 43 and the anode plates 6, 37, 46, and the cathode plates 7, 38, 47 are merely examples, and are within a range not departing from the above technical idea. Of course, various changes can be made.
