[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for a rechargeable battery, for example, to a holder for a rechargeable battery capable of storing a battery in a device using the battery while the battery is mounted.

[0002]

2. Description of the Related Art In a rechargeable battery, for example, a rechargeable battery such as a Nickel-Kadonica battery, maintaining a charged state for a long time shortens the battery life. In particular, when newly charging, it is essential to charge the battery after it has been completely discharged in order to prolong the battery life. Therefore, it is desirable to completely discharge the battery when it is not to be used.

[0003]

However, it is difficult to completely discharge a battery before it is charged, and in most cases, it has been unavoidable to charge the battery in a state of being charged to some extent. Among them, in consideration of such a current situation, a battery charger is provided with a mode for first discharging before charging, and when this mode is selected, the battery once mounted is discharged first, and then the battery is charged. Charging devices are also appearing.

However, since such a charger is generally expensive, such a function is not provided in a usual charger of a rechargeable battery of one to four size, and other expensive electronic devices are not provided. For example, it is only attached to a limited one such as a charger for a dedicated battery such as a video camera.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can sufficiently discharge a general-purpose rechargeable battery which is generally used. Another object of the present invention is to provide a battery holder for a rechargeable battery that can be stored in a battery storage section of an electronic device while being mounted on a battery. Then, the following configuration is provided as one means for achieving such an object.

That is, a plus-side electrode which is in close contact with and electrically connected to the plus pole position of the battery, a minus-side electrode which is in close contact and is electrically connected to the minus pole position of the battery, It has a self-discharge mechanism in which a self-discharge load resistor and a switch are connected in series between the side electrode and the minus side electrode.The plus side electrode and the minus side electrode are formed in a thin shape, and the state of attachment to the battery is improved. It is formed so that it can be stored together with the battery in the battery storage part of the device using the battery while maintaining it.

[0007] For example, the plus side electrode and the minus side electrode are formed so as to be fitted into the plus and minus poles of the battery, respectively, and cannot be mounted on the battery using equipment in the switch-on state.

[0008]

With the above arrangement, it is possible to provide a battery holder for a rechargeable battery which can sufficiently discharge a rechargeable battery and which can be stored in a battery storage portion of an electronic device while being mounted on the battery. The life of the battery can be extended.

[First Embodiment]

FIG. 1 is a diagram for explaining the basic principle of an embodiment according to the present invention, and FIG. 2 is a conceptual diagram of a state where a battery holder of the embodiment is mounted on a battery.

FIG. 1 shows a battery holder for a rechargeable battery according to the present embodiment.
It comprises a positive electrode 12, a load resistor 13 for self-discharge, and a switch circuit 14. The self-discharge load resistor 13 and the switch circuit 14 are connected in series between the negative electrode 11 and the positive electrode 12. FIG. 2 shows the concept of a state in which the battery holder for the rechargeable battery of the present embodiment shown in FIG. 1 is actually mounted on the battery 20, and the minus side electrode 11 and the plus side electrode 12 of the battery holder 10 are respectively The battery 20 to be mounted is held so as to be fitted into the minus electrode 21 and the plus electrode 11 of the battery 20, and the mounted state is maintained as it is.

That is, the battery holder 10 of the present embodiment is configured to be normally usable in a state where the battery holder 10 is mounted on a rechargeable battery 20. For this reason, the plus side electrode 12 is formed by pressing a thin plate-shaped conductor into a shape corresponding to the shape of the plus electrode 22 of the mounted battery by press working or the like, and is configured to be fitted so that the fitted state can be maintained thereafter. Similarly, the negative electrode 11 is formed by molding a thin plate-shaped conductor into a shape corresponding to the shape of the negative electrode 21 of the mounted battery by pressing or the like, and can maintain the state of being fitted into the negative electrode 21.

For this reason, as shown in FIG. 2, the battery holder of this embodiment is mounted on the battery. The rechargeable battery 20 can be easily self-discharged simply by turning on the switch, and can be charged as it is simply by turning off the switch. This is made possible by forming both the minus side electrode 11 and the plus side electrode 12 with a thin plate-shaped conductor.

The resistance value of the self-discharge load resistor can be any resistance value as long as it is not so low. However, if an excessively large current is passed, the calorific value of the resistor itself increases, so that it is desirable to set the resistance to a somewhat large value. The switch can have any shape as long as it is small and does not easily change its on / off state.

In general battery-powered electronic equipment,
An unused battery or a charged rechargeable battery was stored in the battery storage section schematically shown in FIG. That is, the battery 20 is housed between the usually ring-shaped (spring-shaped) minus electrode terminal 31 and the plate-shaped (leaf-spring-shaped) plus electrode 32 in the battery accommodating portion and used. Then, the battery 20 is pressed against the positive electrode terminal 32 by the elastic force of the ring-shaped negative electrode terminal 31 to maintain an electrical connection state and to hold the battery 20.

Here, the battery holder 10 of this embodiment is
As shown in FIG. 2, even when the battery is mounted on the battery 20, its shape is only slightly increased by the thickness of the negative electrode 21 and the positive electrode 22 of the battery 10. By configuring the switch 14 to be small and to be closely attached to the side surface of the battery 20,
As it is, it can be stored in the battery storage section of a battery-driven electronic device.

The battery holder 10 of this embodiment is
FIG. 4 shows a state in which the electronic device is mounted in the battery storage portion of the battery-driven electronic device while being mounted on the electronic device. In the case of FIG.
4 is in an off state. When the battery 20 is not used, for example, when the battery 20 is removed, the switch 14 of the battery holder 10 of this embodiment is turned on, the battery 20 self-discharges by the load resistor 13, and the power remaining in the battery 20 is transferred to the load resistor 13. To consume.

As described above, according to this embodiment, the remaining power can be discharged by the self-discharge load resistor 13 when the battery is not used or before charging, and the life of the rechargeable battery can be extended. can do. [Second Embodiment] In the above description, when the battery is not used or before charging, the remaining power can be discharged by the self-discharge load resistor 13, and the life of the rechargeable battery can be extended. Examples have been described. However, in the above-described embodiment, the shape of the special load resistor 13 was not specified. For this reason, depending on the shape of the switch 14, the switch 14
If the battery 20 is inserted into the battery housing of the electronic device while the power supply is in the ON state, it is possible to anticipate a situation in which the power consumption increases and energy is consumed in a short time. However, this is ill.

Therefore, in the second embodiment according to the present invention, the shape of the switch is devised so that the battery in which the battery holder is mounted cannot be mounted in the battery housing when the switch is turned on, that is, in the state of connection to the load resistance. Will be described below with reference to FIG. FIG. 5A is a top view showing a configuration example of the switch 14 in a state where the switch 14 is attached to the battery 20, and FIG. 5B is a plan view thereof.

In the second embodiment, the negative electrode 2 of the battery 20 is
1 was fitted with the negative electrode 11 of the second embodiment,
The plus electrode 12 is fitted into the zero plus electrode 22. Then, similarly to the first embodiment, the discharge load resistor 13 and the switch 1 are connected.
4 is connected in series between the minus electrode 11 and the plus electrode 12. However, in the second embodiment, unlike the first embodiment, the contact portion of the switch 1 is located at the side surface of the battery 20 shown at 14a, and the switch lever is placed on the upper surface of the positive electrode 22 from the side surface of the battery 20 as shown at 14b in FIG. The battery extends to a slightly higher position and is bent toward the upper surface of the battery. The switch 14 is turned on / off by the switch lever 14b.
Is configured to be performed by swinging.

That is, when the battery is fixed at a position extending upward in FIG. 5 from the side surface of the battery indicated by a chain line in FIG. 5A, the battery can be inserted into the battery housing as a switch-off. The switch position is the position shown in black in FIG. As a result, the switch lever 14b is considerably higher than the positive pole 22 of the battery 20, so that the switch lever 14b cannot be inserted into the battery housing as it is. For this reason, it is possible to prevent the switch 14 from being erroneously inserted into the battery housing with the switch 14 turned on.

The shape of the switch is not limited to the example shown in FIG. 5. If the switch is configured so as not to be inserted into the battery housing in the switch-on state, the shape is not limited at all. For example, in the case of switch-on, the switch lever may be extended to the outside of the battery. As described above, according to the present embodiment, there is no possibility of using the battery in the switch-on state by mistake.

Although the above description has been given of the case where the switch is of a mechanical type, the present invention is not limited to the above example. Alternatively, the switch may be turned on / off.

[0023]

According to the present invention, as described above, according to the present invention, not only can the battery be inserted into the battery housing of the battery-driven electronic device while being attached to the rechargeable battery, but also the battery can be completely removed prior to charging. And the battery life can be prolonged. In addition, it is possible to effectively prevent the battery from being inserted into the battery compartment while being in a self-discharged state by mistake.
Unnecessary battery consumption can be prevented.
