Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery pack, and more particularly to a battery pack in which a plurality of square cells are arranged. 2. Description of the Related Art Various batteries are used as power supplies for small electronic devices, and small, large-capacity sealed batteries are used as power supplies for cellular phones, notebook computers, camcorders, and the like. A sealed battery using a non-aqueous electrolyte such as a high-capacity lithium battery or a lithium ion secondary battery is used. In response to the miniaturization of devices, in addition to cylindrical batteries, rectangular sealed batteries that can effectively use a small space are widely used. [0003] A rectangular cell corresponding to the voltage and current required for these devices is used. However, in the case of a device requiring a voltage and current capacity which cannot be easily handled by the cells. A battery pack capable of outputting a predetermined voltage and current capacity by electrically connecting a plurality of unit cells in series or in parallel is used. Also, since a battery pack provided with a plurality of cells has a large charge / discharge capacity, the battery pack or a device using the battery may overheat, burn out, Protective measures are provided to prevent a dangerous situation such as explosion.Furthermore, in order to be able to reliably stop the charge / discharge operation of the battery even if an abnormality occurs in these protective measures, A temperature fuse is provided that irreversibly shuts off the circuit when the temperature rises above a predetermined temperature. FIG. 3 is a view for explaining a conventional battery pack, illustrating a battery and a temperature fuse disposed in the battery pack, and a view for explaining a battery pack provided with two unit cells. FIG. 2 is a perspective view of the internal battery and the like when seen through. In the battery pack 1 shown in FIG. 3A, two cells 3a and 3b are disposed in a container 2 and closely contact each other with small side surfaces facing each other. Is covered with an insulating member 4 so as not to be formed. A temperature fuse 5 is disposed at the center of both cells so that the circuit can be irreversibly shut off when the temperature of at least one of the cells rises above a predetermined temperature. The fuse 5 is fixed closely to the battery by a heat-resistant synthetic resin material 6 such as a silicone resin or an insulating adhesive tape. [0005] In addition, the temperature fuse is generally a melt fragment,
Alternatively, the protective cover 7 has a structure in which the fused particles are sealed in a glass tube, so that the protective cover 7 can withstand an external impact.
Covered with. In the battery pack, a protection circuit board 8 for protecting the battery from overcharging and overdischarging, and controlling charging and discharging is provided. Connection terminals 9a, 9b, 9c and 9d. In the battery pack 1 shown in FIG. 3 (B), two unit cells 3a and 3b are closely arranged with their side faces having large areas facing each other, and the two units are insulated from each other. Is covered with the conductive member 4. When at least one of the temperature of the cells rises to a predetermined temperature or higher, a temperature fuse 5 is provided at a central portion of a contact portion of the cells so that the energizing circuit can be irreversibly shut off. The temperature fuse 5 is tightly fixed to the battery by a heat-resistant synthetic resin material 6 such as a silicone resin or an insulating adhesive tape. The temperature fuse 5 is covered with a protective cover 7 as in the battery pack shown in FIG. The battery pack is provided with a protection circuit board 8 for protecting the battery from overcharging, overdischarging, and the like, and for controlling charging and discharging. Terminal 9
a, 9b, 9c, and 9d are provided. [0007] In these battery packs, the arrangement of the battery pack is limited due to the relationship of the position of the temperature fuse, and the battery pack specifications when the length in the longitudinal direction and the thickness direction of the battery are minimized are satisfied. It was difficult. Also,
An insulating material such as insulating paper or insulating tape has been required in order to prevent a short circuit between the cells 3a and 3b arranged. Also, since the thermal fuse 5 is arranged on the outer surface,
Since the protective cover 7 for protecting the thermal fuse 5 is indispensable, there has been a problem that the external dimensions of the battery pack are further increased due to the thickness of the protective cover. SUMMARY OF THE INVENTION The present invention relates to a temperature fuse for irreversibly shutting off an energizing circuit when a battery temperature rises above a predetermined temperature in a battery pack in which a plurality of unit cells are arranged. In this case, it is necessary to cover each unit cell with an insulating material so that the outer diameter of the battery pack does not increase and conductive contacts are not formed between cells placed close to each other to adhere to the temperature fuse. It is an object of the present invention to provide a battery pack having no battery. SUMMARY OF THE INVENTION It is an object of the present invention to provide a battery pack in which a plurality of square-shaped cells are arranged, and each cell is closely contacted with a space formed between adjacent cells. This can be solved by a battery pack in which a thermal fuse is arranged and an insulating spacing member is arranged between adjacent batteries. The battery pack according to the above, wherein a spacing member having an opening for mounting a thermal fuse is disposed in a space formed between the cells. Further, the battery pack includes a space formed between unit cells, except for a temperature fuse portion, and a spacing member made of insulating synthetic resin or rubber. The battery pack of the present invention has a structure in which a temperature fuse is disposed in close contact with both cells in a space provided between adjacent cells, and a spacing member is disposed. Since there is no protrusion outside the battery and the temperature fuse does not protrude to the outside, the size of the protective member such as a protective cover for the temperature fuse may be small, and the battery pack can be made thin. Since the conductive contact between the batteries can be prevented by the spacing member,
It has been found that it is no longer necessary to cover the periphery of the unit cell with an insulating member, so that it is easy to manufacture and the size of the battery pack can be reduced. The present invention will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating a battery pack of the present invention. FIG.
FIG. 1A is a perspective view of the inside, and FIG. 1B is an exploded perspective view. The battery pack 1 shown in FIG.
The single cells 3a and 3b are arranged with their side surfaces having small areas facing each other. Between the two cells, when at least one of the battery temperatures rises to a predetermined temperature or higher, the cells are blown to disconnect the electric circuit. A temperature fuse 5 that irreversibly shuts off is provided, and an insulating spacing member 10 is provided between the two cells.
Keeps the gap and protects the temperature fuse. In the battery pack, the battery is overcharged,
Protection circuit board 8 that protects against overdischarge and controls charging and discharging
Are provided on the wall surface of the container 2 of the battery pack, and connection terminals 9a, 9b, 9c, and 9d for connection with equipment using a battery, a charger, and the like are provided. As shown in an exploded perspective view of FIG. 1B, the spacing member 10 disposed between the two cells 3a and 3b has a contact opening 11 matching the temperature fuse 5.
Is formed, and the temperature fuse can be arranged closely to the side surfaces of the two unit cells adjacent to each other. As a result, the temperature fuse 5 is tightly fixed to the battery by a heat-resistant synthetic resin material 6 such as a silicone resin, an insulating adhesive tape or the like, and the temperature fuse 5 is connected to the other battery by the close-contact opening 11 provided in the spacing member 10. Are also arranged closely. in this way,
The temperature fuse is located in the space between the unit cells and is in close contact with both batteries, so the temperature fuse is protected by both cells. The size of the battery pack can be reduced without adverse effects. FIG. 2 is a diagram for explaining another embodiment of the present invention. As shown in FIG. 2 (A), a temperature fuse 5 is disposed in close contact with both unit cells 3a and 3b with a heat-resistant synthetic resin material 6, and as an interval holding member between the unit cells, an insulating space holding member is provided. The rubber material 12 is arranged. Also,
FIG. 2 (B) shows that the temperature fuse 5 is disposed in close contact with both of the unit cells 3a and 3b with the heat-resistant synthetic resin material 6, and the portion where the temperature fuse 5 is not provided is also filled with the heat-resistant synthetic resin material. In this way, the space keeping filler 13 is formed. Thereby, the formation of the spacing member and the close contact of the temperature fuse 5 with the unit cell can be realized by the same material. According to the battery pack of the present invention, the temperature fuse can be disposed in close contact with the adjacent unit cell while preventing conductive contact between the adjacent unit cells. Since it does not protrude from the outer surface of the battery pack, the protective member for the temperature fuse can be thinned, and the size of the battery pack can be reduced.
