Description

POE switching power adapter

technical field

The invention relates to a relay device of an Ethernet network, in particular to a POE switching power supply adapter which simultaneously transmits data and direct current through an unshielded twisted pair.

Background technique

With the application of wireless Ethernet more and more widely, the problem of power supply of network equipment of wireless Ethernet is becoming more and more serious. Referring to Figure 1, since wireless Ethernet network devices such as wireless routers, IP phones, network cameras, wireless bridges, cash registers, etc. It is difficult to have a suitable power socket nearby, the user must install the AC-DC converter in a suitable place, and then connect the network equipment through the wire, the wiring is troublesome, and even if there is a socket nearby, the AC-DC converter required for these devices is placed It's also quite a headache for users there.

In addition, in many large-scale wireless local area network applications, administrators need to manage multiple network devices at the same time, and these network devices need unified power supply and unified management, which requires a separate uninterruptible power supply (UPS) for each network device. In addition, power sockets need to be installed near the wireless access equipment, which not only increases the cost, but also makes it difficult to manage and maintain. It also faces problems such as troublesome wiring and headaches for users due to the location of AC-DC converters.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a POE switching power supply adapter for an Ethernet network relay device that simultaneously transmits data and direct current through an unshielded twisted pair.

The technical solution adopted by the present invention to solve its technical problems is:

POE switching power supply adapter, including switching power supply circuit, RJ-45POE port for connecting network equipment and RJ-45LAN port for connecting input network cable, said RJ-45POE port and RJ-45LAN port part are electrically connected to corresponding terminals, so The input terminal of the switching power supply circuit is connected to the power supply, and the output terminal is connected to the RJ-45POE port.

Detailed ways

Refer to Figure 2 and Figure 3, POE (Power Over Ethernet) switching power supply adapter, including switching power supply circuit, RJ-45POE port for connecting network equipment and RJ-45LAN port for connecting input network cable, the RJ-45POE port It is electrically connected to the corresponding terminal of the RJ-45LAN port part, the input terminal of the switching power supply circuit is connected to the power supply, and the output terminal is connected to the RJ-45POE port.

Although the unshielded twisted pair has 4 pairs of 8 core wires, only 4 of them are actually used in the network, namely the 1st, 2nd, 3rd, and 6th terminals of the crystal head. The function of receiving and sending signals, and the other 4 terminals, namely the 4th, 5th, 7th and 8th terminals of the crystal head, are idle. The first, second, third, and sixth terminals of the data transmission terminals corresponding to the RJ-45POE port and the RJ-45LAN port are electrically connected.

As a further improvement of the present invention, the output terminal of the switching power supply circuit is connected to the idle terminal of the RJ-45POE port, the 4th, 5th, 7th, and 8th terminals are idle, and the 4th and 5th terminals are connected to the positive pole of the switching power supply circuit Output terminal, the 7th and 8th terminals are connected to the negative output terminal of the switching power supply circuit.

The POE switching power supply adapter of the present invention simultaneously transmits data and DC power through an unshielded twisted pair, does not need to provide a separate power cable for each network device, simplifies installation, greatly reduces equipment costs and management costs, and network devices can be used It can be installed at any location without being close to an existing power socket, which improves the flexibility of installation. In large-scale wireless LAN applications, only one uninterruptible power supply (UPS) is required to supply power to meet all wireless Ethernet requirements. It simplifies the network structure, because it is a relay device added on the basis of the existing network, without replacing the existing network equipment and changing the existing network structure, it can be easily realized through The purpose of the network cable to transmit data and DC power can be widely used in IP telephones, network cameras, wireless bridges, cash registers, security access and monitoring systems based on unshielded twisted pair transmission data.
