JP3070568U - Battery pack with DC socket for charging - Google Patents

Abstract

(57) [Object] To develop a battery pack having a connection socket that can easily supply electricity to a portable telephone, a portable personal computer, a portable radio, etc. using a portable generator without a power source. . The battery pack of the present invention has a conventional charging method by equipping the battery pack with a DC socket for connecting the portable generator and the battery pack with a cable,
It is characterized in that a DC socket is newly provided to facilitate charging by a portable generator or the like.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a battery pack that is not connected to a power source when a battery such as a portable telephone, a portable personal computer, a portable radio, or the like using a battery pack is consumed in a place where there is no power supply. And a battery pack provided with a charging DC socket capable of directly supplying electricity to the battery pack.

[0002]

[Prior art]

 Today, portable telecommunications equipment such as mobile phones, portable personal computers, and GPSs using battery packs have become widespread, but the batteries used for these are either rechargeable batteries powered by an external power source or disposable batteries. There is a limit to the power storage capacity, and it is often confused that the stored power is consumed halfway.

In an emergency disaster, a portable radio, a flashlight, and the like are required to be carried, but since these devices are not normally used and are left alone, there is a great risk that the batteries will be naturally discharged and consumed. is there.

[0004] In such a case, charging is usually performed using a charger attached to the device, generally a charger that converts AC to DC of a commercial power supply, or charges using a vehicle power supply. There are some methods, but none of them can be implemented in a place without external power supply.

In view of the above, the present applicant has generally proposed the use of a small-sized portable generator, which has already proposed utility model registration No. 3053139 and Japanese Patent Application No. 11-311691, in the form of a clutch gear, The intermediate gear and the drive shaft gear are driven and rotated, the generator rotor is rotated to generate electricity, and electricity is extracted from the output cord. It stores electricity in a rechargeable battery or rechargeable battery pack.

[0006]

[Problems to be solved by the invention]

 However, in the case of a conventional battery pack, charging must be performed using a charging cable dedicated to the device, so that various cables have to be prepared.

[0007]

[Means for Solving the Problems]

 According to the present invention, a DC power cable 5 that matches the DC power socket 3 attached to the battery pack is prepared without using the charging cable 9 dedicated to the device 8, so that a portable device such as Utility Model Registration No. 3053139 can be easily provided. With a type generator, the battery can be dealt with immediately at any time and anywhere. Further, since the same product is manufactured in manufacturing the DC power cable jack 5, the manufacturing cost can be reduced, and it can greatly contribute to economical and environmental problems.

[0008]

[Embodiment of the invention]

 The present invention comprises a rechargeable battery unit 1, a power supply control circuit unit 2 for supplying electricity to the battery, a DC socket 3 provided by the present invention, and a main body case 4 for accommodating them.

[0009]

【Example】

 FIG. 1 is a diagram showing the internal arrangement of a battery pack case, in which electrodes 6 and 7 are in contact with a dedicated device 8 such as a mobile phone, and are connected from an external power supply connection terminal to a dedicated charging cable 9 for charging. Is generally performed.

[0010] In rare cases, a battery pack having electrodes 6 and 7 that come into contact with equipment and an exposed electrode connected to each of them is seen. This battery pack is connected to a commercial power source or the like via an external power charger cable 11. When the battery is inserted into the external power supply charger 10, the electrode surfaces come into contact with each other to perform charging.

In the present invention, the DC power supply socket 3 is simply attached in parallel to the primary side of the power supply control circuit section 2 for simply supplying electricity to the battery as shown in FIG. 1 without impairing the function of the conventional battery pack. It is a thing. Also, depending on the performance of the battery used, the connection from the DC power socket 3 can be directly attached to the positive and negative electrodes of the battery.

[0012] In actual use of the present invention, the electric power from the charger is obtained by using a conventional method of charging with an external power supply or using a portable generator or the like in the absence of an external power supply. The DC power cable jack 5 is inserted and connected to the socket 3 to allow easy charging.

[0013]

[Effect of the invention]

 Based on the above configuration, the present invention can use a conventional charger with an external power supply when supplying electricity to a battery pack of a portable telephone, a portable personal computer, a portable radio, etc. In the absence of electricity, charging using a portable generator is easily possible, and there is no need to rely on 100% of external power sources that use electricity generated by fossil fuels, nuclear power, etc. It is a device that can contribute.
