Abstract
The utility model discloses a network distribution frame based on POE power, network distribution frame (2) are including one POE power (4), a RJ45 interface module and one PCB board (5), RJ45 interface module has 24 RJ45 interfaces, the output voltage of every RJ45 port is 48V, PCB board (5) respectively with every RJ45 electrical connection interface, the positive pole of POE power (4) passes through the winding displacement and is connected with fourth pin, the 5th pin electricity that network distribution frame (2) corresponds the port, the negative pole of POE power (4) passes through the winding displacement and is connected with the 7th pin, the 8th pin electricity that network distribution frame (2) corresponds the port. Through the technical solution, the utility model has the advantages of the interface is many, the fault rate is low, with low costs.
Description
Technical field
The utility model relates to low-voltage power supply equipment technical field, particularly relates to a kind of network wiring frame based on POE power supply.
Background technology
In recent years, along with the fast development of electronic communication equipment, kind and the equipment of low voltage equipment are on the increase, therefore, different low voltage equipments is directed to, such as network power supply, it is general it is desirable that the low-voltage dc power supply of 48V, so POE technology is arisen at the historic moment, along with the quick growth of network power supply demand.The now general network switch does not have network power supply function, and the POE network switch that can power is expensive.For the existing network switch but for the user needing network power supply, more the cost of transducer switching system is too high.Given this situation is planted, people develop a kind of network wiring frame with power supply, as China Patent No. is: 201420569620.2, denomination of invention discloses a kind of network wiring frame with power supply in " POE supply network distributing frame ", but being found by practice, there is following technological deficiency in technique scheme: one, the quantity (18) of output port is difficult to the demand meeting power supply; Two, complex structure, each RJ45 interface group needs a pcb board, therefore at least needs three pcb boards, so just there is the defect that failure rate is high, cost is high.
Utility model content
The technical problems to be solved in the utility model is: according to the needs of network power supply, network power supply will be realized, a kind of network wiring frame based on POE power supply that 24 output ports can be provided simultaneously for this reason designed and developed under not there is user the prerequisite of the POE network switch.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
Based on a network wiring frame for POE power supply, described network wiring frame (2) comprises a POE power supply (4), a RJ45 interface module and a pcb board (5); Described RJ45 interface module has 24 RJ45 interfaces; The output voltage of each RJ45 port is 48V; Described pcb board (5) is electrically connected with each RJ45 interface respectively; The positive pole of described POE power supply (4) is electrically connected by the 4th pin of winding displacement and network wiring frame (2) corresponding ports, the 5th pin; The negative pole of described POE power supply (4) is electrically connected by the 7th pin of winding displacement and network wiring frame (2) corresponding ports, the 8th pin.
Further: described POE power supply (4) be installed on distributing frame port below or above.
The advantage that the utility model has and good effect are:
By adopting technique scheme, the utility model adds POE power supply on the network wiring frame of legacy network rack, therefore makes legacy network distributing frame not only have the function of exchanges data, has for the network equipment provides the function of electric energy simultaneously; Active network distributing frame is become by traditional passive network distributing frame; RJ45 interface module simultaneously in the utility model has 24 RJ45 interfaces, therefore, it is possible to export 24 road signals simultaneously, meets the demand of multiplex roles.
Because the positive pole of the power supply of POE described in the utility model is electrically connected by the 4th pin of winding displacement and network wiring frame corresponding ports, the 5th pin; The negative pole of described POE power supply is electrically connected by the 7th pin of winding displacement and network wiring frame corresponding ports, the 8th pin; Therefore there is wiring advantage simply and easily; Found through experiments, above-mentioned connected mode can ensure that each RJ45 port exports a stable 48V power supply, so the utility model also has the high advantage of stability well simultaneously.
Because the utility model adopts one piece of pcb board to be RJ45 interface module conveying data, therefore have failure rate is low, structure is simple, the advantage that cost is low.

Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of network wiring frame based on POE power supply, described network wiring frame 2 comprises a POE power supply 4, RJ45 interface module and a pcb board 5; Described RJ45 interface module has 24 RJ45 interfaces; The output voltage of each RJ45 port is 48V; Described pcb board 5 is electrically connected with each RJ45 interface respectively; The positive pole of described POE power supply (4) is electrically connected by the 4th pin of winding displacement and network wiring frame 2 corresponding ports, the 5th pin; The negative pole of described POE power supply 4 is electrically connected by the 7th pin of winding displacement and network wiring frame 2 corresponding ports, the 8th pin; During use, network wiring frame 2 is installed on the inside of network cabinet 1;
24 RJ45 interfaces of network wiring frame have taken whole network wiring frame under normal circumstances.Therefore, in implementation process, POE power supply is placed without space in the front end of network wiring frame, therefore preferred version be POE power supply 4 is placed on distributing frame port below or above; Found by many experiments, above-mentioned connected mode can ensure that each RJ45 port exports a stable 48V power supply well.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
