Description

Power adapter with USB connector 【0001】

This creation relates to adapters, and more particularly to power adapters.

【0002】

Nowadays, the electronics industry is developed, and various electronic devices are filled with the general public's life. In order to transmit control commands, multimedia materials and even power, most electronic devices are equipped with one or more connectors.

[0003]

In terms of transmission power, the Universal Serial Bus (USB) 2.0 and USB 3.0 connectors widely used in the market can be used to transmit power when external devices such as flash drives, external hard disks or When an external optical disc drive or the like is plugged into an electronic device via a USB connector, power can be directly received from the electronic device to operate. In addition, the smart mobile devices and tablets commonly used in the market can also be connected to a desktop computer, a notebook computer or a commercial power source through a USB connector for charging.

[0004]

However, due to the insufficient number of power terminals of the USB2.0 and USB3.0 connectors, only a small output/input current can be provided. Therefore, the power provided by the USB2.0 and USB3.0 connectors is insufficient. To provide all the power needed to operate some electronic devices (such as desktops, notebooks, computers, etc.), which is why these electronic devices still need to be plugged into the mains to operate or to charge their batteries.

[0005]

To address the issue of insufficient output/input current, the USB Association has unveiled a new form of USB connector for the USB C-Type connector. The USB C-Type connector provides a large output/input current, thus providing all of the power required to operate the electronic devices described above.

[0006]

However, in the development of the market, some electronic devices may be provided with the USB C-Type connector, and some electronic devices do not have the USB C-Type connector. In addition, some new power supplies may directly use the USB C-Type connector as the main power output interface, but the old power supply still uses the traditional power plug as the power output interface. As a result, the problems that the electronic devices and the power supply are incompatible with each other will be caused.

【0007】

The main purpose of the present invention is to provide a power adapter having a USB connector, which can receive power from a power supply and, after processing, externally output via a USB connector, thereby directly providing an electronic device by a USB connector. All the electricity needed to operate.

[0008]

In order to achieve the above purpose, the power adapter of the present invention comprises a circuit board, a processing circuit, a USB connector male connector and a power connector, wherein the processing circuit, the USB connector male connector and the power connector are electrically connected to the circuit board respectively. on. The power adapter plugs into an external power supply through a power connector and plugs in an external electronic device through a USB connector. The power connector receives power from the plugged power supply and transmits it to the processing circuitry on the board for processing before passing it to the USB connector male. Thereby, the male connector of the USB connector transmits power to the plugged electronic device to provide power required for the operation of the electronic device.

【0009】

The technical effect that the present invention can achieve according to the prior art is that the power adapter can process the received power and directly output it through the male connector of the USB connector. Therefore, an electronic device can pass the corresponding USB. The connector female is connected to the power adapter of the author and receives power from the power adapter from the power adapter. In this way, the power interface on various electronic devices can be effectively unified into a USB connector.

[0010]

In addition, with the power adapter of the present invention, the electronic device can receive all the power required for operation directly through the USB connector thereon, so that it is no longer necessary to retain the conventional power socket to plug in the power supply. In this way, the output/input interface on the electronic device can be simplified, and the volume of the electronic device can be greatly reduced, and the manufacturing cost can be effectively reduced.
