Abstract

The utility model provides a connection device for realizing the co-cable transmission of data signals and power signals, which comprises a RJ45 connection port, a wire bonding module and a power socket. First, second, third and sixth pins of the RJ45 connection port are respectively and correspondingly connected with first, second, third and sixth pins of the wire bonding module; seventh and eighth pins of the wire bonding module are mutually connected and then connected with the negative pole of the power socket; and fourth and fifth pins of the wire bonding module are mutually connected and then connected with the positive pole of the power socket. The device realizes the co-cable transmission of the data signals and the power signals through the wire bonding module; as the wire bonding module is tightly connected with a network cable, the risk that the pins of the RJ45 connection port are burnt because the RJ45 connection port is adopted to transmit the power signals in the prior art and the current is overlarge can be avoided; and the connection device can ensure that the transmission voltage reaches DC 220V to 240 V, and the transmission current reaches 2 A, thereby reducing the loss of lines while meeting the power supply requirement of network equipment.

Description

A kind of data-signal and power supply signal termination of cable transmission altogether of realizing

Technical field

The utility model relates to a kind of data-signal and power supply signal termination of cable transmission altogether of realizing, specifically, relates to a kind of data-signal and power supply signal termination of cable transmission altogether that makes in Ethernet comprehensive wiring field.

Background technology

In Ethernet comprehensive wiring field, a lot of network equipments all need external direct current power supply, construction for convenience and saving cost, need the cable transmission altogether of data-signal and power supply signal, under the situation that Ethernet wiring architecture does not make any changes, when being network equipment transmission of data signals, kind equipment provides the technology of direct current supply for this reason, the Power over Ethernet technology POE technology that Here it is uses at present.

The POE technology has two types, first kind is the POE equipment according to the IEEE802.3af standard design, the POE function is integrated in network device internal, be divided into power supply unit and power receiving equipment, have the intelligent management ability, but this type of POE equipment, equipment manufacturing cost is relatively costly, and the equipment beyond can not compatible IEEE802.3af standard, application is limited.

Second type is a pair of identical termination of cross-over connection between the network equipment, by the RJ45 Wiring port on the termination, carries out the common cable transmission of data and power supply signal.Its operation principle as shown in Figure 1, first, second and third of the RJ45 Wiring port 11 of the network equipment 1, six pins, first, second and third of short-term 5 by having crystal head and the RJ45 Wiring port 21 of termination 2, the corresponding connection of six pins, after fourth, fifth pin of RJ45 Wiring port 21 is connected, be connected with the anodal V+ of network electric power 7, after the 7th, eight pins of RJ45 Wiring port 21 connect, be connected with the negative pole V-of network electric power 7, thereby make the data-signal of the network equipment 1 and the power supply signal of network electric power 7 transfer to RJ45 Wiring port 21; By standard C AT5 network cable 6, according to the normal line preface, the RJ45 Wiring port 31 long distances of RJ45 Wiring port 21 and termination 3 are connected, thereby make 31 acquisitions of RJ45 Wiring port from the data-signal of the network equipment 1 with from the power supply signal of network electric power 7; With RJ45 Wiring port 31 first, second and third, the RJ45 Wiring port 41 of six pins and the network equipment 4 first, second and third, six pins connect one to one by the short-term 5 of band crystal head, fourth, fifth pin and the 7th of RJ45 Wiring port 31, eight pins are connected one to one by the lead short distance with the positive pole and the negative pole of the supply socket 42 of the network equipment 4 respectively, obtain from the data-signal of the network equipment 1 with from the power supply signal of network electric power 7 thereby make network be equipped with 4, so realize data-signal and power supply signal altogether cable transmit.
