[Previous technology] In the past, network equipment usually used two independent wires for "data" and "power" transmission, and the wires used to transmit data usually used rj_45 connectors and four twisted pairs (twisted pair). ) Combination, but since only two pairs of twisted pairs are needed for data transmission, the four pins on the RJ-45 connector (pins 4, 5, 7, and 8) and two pairs of double Twisted wires are left idle, so in order to make full use of existing equipment resources and for convenience, the industry has developed "Power over Ethernet" (POE). The original intention is to use this idle pin and twisted pair for power transmission. In this way, the network equipment no longer needs an external power supply, and the required power can be uniformly supplied by a central network device, and the central network device can be equipped with a continuous power system (UPS) to ensure a blackout day All network devices connected to it can work normally. △ Due to the matching of goals, power Internet technology has gradually become a necessary base for wireless networks. Because of the characteristics of wireless networks, it is often necessary to place the base station at a point π in the air to enhance the reception range. These places are usually not designed with power sockets. Therefore, unless the location of the power socket is relocated, it must be carried out. The additional distribution of 200428800 electricity projects is not economically beneficial. However, the power access technology can make the installation of the base station more flexible without being limited to the location of the power supply. However, the traditional architecture often encounters some problems. For example, if the central network equipment does not support the Internet access technology, or the required power is greater than the maximum power supply provided by the central network equipment, the traditional central network The equipment is not what you need. [Summary of the Invention] The main purpose of the present invention is to provide a power injector device that can provide two types of power sources at the same time, one is to transmit the power source through the network, and the other is to supply the power source from the city power, so as to increase the flexibility in use. Another object of the present invention is to provide a power injector device, which can prevent terminal equipment from being unusable because the power required by the terminal equipment is greater than the maximum power supplied by the network switch or hub. According to the above-mentioned purpose, the present invention provides a power injector device that can provide two types of power sources for terminal equipment, one is the power source transmitted by the Ethernet network, and the other is the power source supplied by the city electricity. When the power supply is greater than the maximum power supply provided by the network switch or hub, this terminal device can choose to be supplied by the commercial power source, so it can avoid the terminal device being unusable due to insufficient power, and within the permitted range of the terminal device, also Optionally, the power source can be transmitted by Ethernet.

On the other hand, an Ethernet network (not shown in the figure) will be connected to the RJ_45 connector 204 of the terminal device for transmitting data. In other words, when the terminal device does not support the power Internet technology, the invention can be passed The AC mains power supply is directly selected, and the present invention uses the transformer of the terminal device to perform the voltage stabilization work, so an adapter is not required, so the structure is more cost-effective. On the other hand, referring to the fourth figure, it is a schematic diagram of the power injector 400 according to the second embodiment of the present invention. In this embodiment, a coupler 106 can also be used to receive an RJ-45 connector after receiving a data signal. 102, to connect with another RJ-45 connector 104, a conductive wire 108 connected to this coupler 106 transmits the power provided by the AC mains 110 to the coupler 106, and feeds it through the coupler Into RJ-45 connector 104. At this time, power and data are coupled in the same twisted pair for transmission to the terminal equipment. 10 200428800 When using the above-mentioned power injector device 400, the user's subsequent terminal equipment can also choose to connect RJ-45 connector 104 or connector 122. In other words, if the terminal equipment used by the user supports power When using Internet technology, you can choose to connect RJ-45 connector 104 at this time to receive data and power at the same time. Conversely, if the terminal equipment used does not support the power Internet technology, you can choose to connect the connector 122 to provide power, and use another transmission line to transmit data.
