Power adapter

Abstract

An adapter is applied to terminal equipment. The adapter comprises the following components: an alternating-current / direct-current conversion unit configured to be connected with a first alternating-current power supply interface when inserting the adapter in an alternating-current power supply and used for converting the alternating-current power supply from the first alternating-current power supply interface into direct-current power supply with first voltage, a power supply wire configured to be connected with the alternating-current / direct-current conversion unit and used for transferring to direct-current power supply from the alternating-current / direct-current conversion unit, and a first power line modulation-demodulation unit configured to be connected with the alternating-current power supply when inserting the adapter in the first alternating-current power supply interface and used for obtaining high-frequency network signals loaded on the alternating-current power supply, wherein the first power line modulation-demodulation unit loads the obtained high-frequency network signals onto the direct-current power supply of power lines.

Description

Technical field [0001] The present invention relates to a power adapter, and more specifically, the present invention relates to a power adapter with network signal transmission capability. Background technique [0002] Currently, with the development of communication technology, terminal devices such as smart phones or tablet computers can use wireless or wired methods to access the Internet. For example, when the terminal device has a 2G, 3G, 4G or wifi module, the terminal device can access the World Wide Web through a 2G, 3G, 4G or wifi network. In addition, when the terminal device has an Ethernet interface, the terminal device can also access the World Wide Web through a wired network. However, when the terminal device is located indoors, the signal strength of 2G, 3G, and 4G is usually poor. Therefore, it often happens that the network cannot be connected or the network speed is very slow indoors. In addition, when the terminal device uses the wifi module to access the I...

Problems solved by technology

However, when the terminal device is located indoors, the signal strength of 2G, 3G, and 4G is usually poor, so it often happens that the network cannot be connected or the network speed is very slow indoors

In addition, when the terminal device uses the wifi module to access the Internet, because the wifi signal has poor wall penetration ability, the experience of using the wifi network to connect to the Internet is poor when the terminal device is far away from the wireless router or there is a wall blocking the wifi signal. Moreover, in the case of strengthening the wifi signal to enable the terminal equipment to ensure a stable network connection, an overly strong wifi signal also poses a potential threat to human health
