network power adapter

technical field

The utility model relates to a network power supply technology, in particular to a network power supply transfer device.

Background technique

Power over Ethernet (PoE) is a technology that simultaneously transmits power and data provided by a power supply device to a power receiving device through a network cable in an Ethernet network. Power over Ethernet technology can be used in Internet phones, wireless base stations, network cameras, computers and other devices. As long as the power receiving device supports the Power over Ethernet specification, it can receive power and data through Power over Ethernet without the need for additional power sockets to operate, so the power receiving device can save the configuration, time and cost of power supply and power cords. It also simplifies the layout of the entire Ethernet system and reduces the cost relatively.

Since the receiving end device must support the PoE specification before it can be directly connected to the network cable to obtain the above-mentioned benefits, there are PoE adapters on the market that can provide DC power to electronic devices that do not support PoE. Manufacturers generally produce PoE adapters for their own electronic devices that do not support network power supply. Therefore, in the PoE adapters, a dedicated DC power connector that is specific to the specifications of the electronic device is used to connect to their own electronic devices. . The Power over Ethernet adapter in this application scenario can only power dedicated electronic devices.
