JP3069705U - Device to charge mobile phone battery from personal computer - Google Patents

Abstract

(57) [Summary] [Purpose] If there is a personal computer, it can be charged at any time without a mobile phone charger. [Composition] It consists of a PC connector, wiring, and a mobile phone connector with a transformer circuit.

Description

[Detailed description of the invention]

 This device is a device that can be charged at any time from the terminal of a personal computer in order to prevent the increasing number of PC users from becoming unable to talk due to forgetting to recharge their mobile phone in recent years. The personal computer has a terminal to which an external storage device can be externally attached, but that terminal has power for driving, so use it. If this is illustrated in the diagram, when the connector that fits the PC is inserted into the PC, the power of the PC is supplied and the battery of the mobile phone is charged through the connector for the mobile phone with the transformer circuit.

[Effect of the invention]

 By using this device, PC users do not need to carry a mobile phone charger at all times, and they do not create the garbage of used batteries like battery chargers that have already been commercialized. In addition, since the device itself is almost a cable only, it has the advantage that it can be charged at any time without being packed.

[Correction contents] [Detailed description of the invention]

 1. Conventional mobile phone chargers are limited to 100V household power supply, car cigarette lighter or dry battery charging method. Businessmen who frequently travel on public transportation are required to use laptop battery chargers as well as mobile phone chargers. You also need to carry a phone charger. 2. Recently released PCs have a USB terminal as standard, and the battery life of notebook PCs has been extended. The power supply for the connected peripheral devices is supplied to the USB terminal of these personal computers, and this device uses this to charge the battery of the mobile phone. 3. This device consists of a USB terminal, a cable, a circuit for transforming the PC voltage to a mobile phone voltage, and an external connection terminal for a mobile phone. 4. Attach the charging USB terminal to one end of the cable and the external connection terminal of the mobile phone to the other end. Then, at least one of the USB terminal for charging and the external connection terminal for mobile phones is provided with a transformer circuit for converting the voltage for personal computers to the voltage for mobile phones. 5. If you explain this in the figure, the “USB terminal for charging” attached to one end of the “cable” is a terminal connected to the “USB terminal” of the “PC” and receives the supply of the electric power of the PC voltage to the “transformer circuit”. To the mobile phone voltage. The “external connection terminal of mobile phone” attached to the other end of the “cable” is a terminal that matches the “external connection terminal for battery charging of mobile phone” of the “mobile phone”. Charge the battery. 6. In this figure, the transformer circuit is incorporated in the external terminal of the mobile phone for convenience of explanation. 7. Further, if an LED is provided in the transformer circuit and the excess current is consumed by the LED using the voltage difference, the overcharge prevention device is provided.
