DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rechargeable battery pack which is mounted in a dry battery storage portion of an electric device instead of a dry battery, and to a power supply device having the battery pack.

[0002]

2. Description of the Related Art Electric equipment can be used economically by repeatedly charging and discharging many times by using a rechargeable battery pack instead of a dry cell. In particular, like a game console,
Electric equipment with a long usage time and a huge amount of usage,
There is a feature that the amount of discarded dry batteries can be significantly reduced by replacing the dry batteries with the pack batteries. The battery pack that can be used in place of the dry cell battery is Jitsuho 6-4401.
No. 1 publication. In the battery pack described in this publication, two cylindrical batteries 15 are arranged in parallel and connected by a holder 4 as shown in FIG.

[0003]

When the battery pack shown in this figure is installed in the battery compartment instead of the battery,
Replace the battery cover that has closed the opening of the dry battery compartment for the battery pack. This is because the outer shapes of the battery pack and the dry battery are different. When using a dry battery, the opening of the dry battery housing is closed with a battery cover, and when using a battery pack, the opening is closed with a closing lid. Using the battery lid and closure lid,
In the structure for closing the opening of the dry battery storage unit, it is necessary to store the closing lid when using the dry battery and to store the battery lid when using the battery pack. This structure has a disadvantage that the detached battery lid may be lost when not used, and the storage is troublesome. In particular, when using dry batteries, it is necessary to store both the battery pack and the closing lid.

[0004] By making the closing lid integral with the battery pack, storage of the closing lid can be simplified. However, if the battery pack is used in place of a dry battery, it is necessary to design the battery to be smaller if the closure lid and the pack battery are integrated in order to fit into the dry battery compartment designed to fit the dry battery. There is. In particular, a battery pack having an integral structure of a closing lid that is tiltably connected to an opening of a dry battery storage section via a detachable hinge portion needs to be thin. This is because, as shown in FIG. 2, the partition ribs 43 provided in the dry cell storage unit 2 for disposing the dry cells in the fixed position collide with the batteries and make it impossible to mount them. In order to prevent the battery from hitting the partition rib 43, the battery pack needs to be thin. A battery has a drawback that when it is made thinner, the charge capacity is significantly reduced and the use time is considerably shortened.

[0005] The present invention has been developed with the object of solving such drawbacks. An important object of the present invention is to prevent the closure lid from being removed from the electric equipment from being lost,
It is an object of the present invention to provide a battery pack that can be used for a long time by making the battery of the battery pack thick and large, and a power supply device including the battery pack.

The switch 21 is turned on by being pushed by a switch partition rib 55 provided in the dry cell storage section 2. The switch 21 that is turned on by the partition rib 55 is provided in a valley of the secondary battery 3. Further, the switch 21 has an elastic contact at a position pressed by the partition rib 55, and a fixed contact at a position where the elastic contact pressed and deformed by the partition rib 55 contacts.

When the battery pack is taken out of the electric device 1, the elastic contact is no longer pressed by the partition ribs 55, and the switch 21 is turned off. However, the secondary battery 3 is not short-circuited.

As shown in FIG. 4, the battery pack is connected to the discharge terminal 10 and the charging terminal 22 by bifurcating one electrode terminal side of the battery, and discharges one branch path through the switch 21 through the switch 21. The other branch connected to the terminal 10 and connected to this branch is connected to the charging terminal 22 via the diode 54. In this battery pack, no short-circuit current flows even when metal comes into contact with both the charging terminal 22 and the discharging terminal 10 in a state where the battery is removed from the electric device 1.

Further, in the battery pack, as shown in the circuit diagram of FIG. 5, the branch point connected to the charging terminal 22 and the discharging terminal 10 is connected to the electrode terminal of the battery via a single switch 21. You can also. Further, a plurality of batteries can be connected in series by a switch. The battery packs of the circuit diagrams shown in these figures can prevent short-circuiting of both the charging terminal 22 and the discharging terminal 10 in a state where the battery is taken out of the electric device 1.

The elastic clamping projection 63 is provided with slits on both sides so that it can be elastically deformed when a battery is taken in and out.

The battery cover 56 of the dry battery holder 57 has a hinge portion 47 and a lock portion 50 having the same structure as the closing cover 31 of the battery pack at both ends, and the hinge portion 47 and the lock portion 5 are provided.
At 0, it is attached to the dry cell storage unit 2. As shown in these figures, the dry cell storage section 2 in which dry cells are placed in the dry cell holder 57 can be mounted with a battery pack containing a secondary battery having the same thickness and length as the dry cells. For this reason, the capacity of the secondary battery can be extremely increased by using, for example, an AA type secondary battery as the battery pack. Another advantage is that the cost of the secondary battery can be reduced by using a large number of commercially available secondary batteries having the same dimensions as the dry battery.

Further, as shown in FIG. 8, the battery pack can be carried in a dedicated battery box 64 while being detached from the electric equipment. This battery box is formed in a box shape having an upper opening in which both the battery pack and the dry cell can be detachably stored. When putting dry batteries in the battery compartment of electrical equipment, put the battery pack in the battery box, and when putting battery packs in the battery compartment, put the dry batteries in the battery box. When storing the battery pack in the battery box 64, the closing lid 31 is attached to the upper opening.

Is stored in the box, so that the battery pack removed from the electrical equipment can be safely protected without short-circuiting. For this reason, by using the battery box 64, it is possible to use the battery pack which is not used by using the dry battery for the electric equipment, or to use it very conveniently when carrying or storing the battery pack.

Further, the battery box 64 shown in FIGS. 8 and 9 has a structure in which both the battery cover 56 and the closing cover 31 can be detachably attached to the opening. The closing lid 31 of the battery pack is attached to the opening of the dry battery storage in place of the battery lid 56. For this reason, the battery box in which the closing lid of the battery pack can be mounted can be mounted so that the battery lid can also be removed.

When a dry battery is used for the electric equipment, the battery box 64 of this structure stores the battery pack removed from the electric equipment. At this time, the opening of the dry cell storage section in which the dry cells are mounted is closed with the battery lid. As shown in FIG. 3, when a battery pack is used for the electric device 1, the dry battery taken out of the electric device is stored in a battery box, and the dry battery in the battery box is closed with a battery cover. Further, the battery box 64
