The POE switch power source adapter
Technical field
The utility model relates to a kind of trunking of ethernet network, particularly a kind ofly transmits data and galvanic POE switch power source adapter simultaneously by unshielded twisted pair.
Background technology
Along with wireless ethernet is used more and more widely, the network equipment powerup issue of wireless ethernet is also more and more higher compels.With reference to Fig. 1, because the network equipment of wireless ethernet such as wireless router, IP phone machine, network camera, wireless bridge, cashier's machine etc. need direct current to supply electric power, and these equipment are installed in usually apart from ground and locate as ceiling etc. than higher, be difficult to suitable supply socket near it, the user must be installed in AC/DC changeover switch suitable place, connect the network equipment by lead then, the wiring trouble, moreover, even near socket is arranged, the AC/DC changeover switch that these equipment need is placed in the there and also makes very much user's headache.
In addition, in a lot of large-scale WLAN (wireless local area network) are used, the keeper needs to manage a plurality of network equipments simultaneously, these network equipments need unified power supply and unified management again, this just needs to give each network equipment to be equipped with a uninterrupted power supply (ups) Unity separately, but also supply socket need be installed near radio reception device, has not only increased cost, be not easy to again administer and maintain, and face wiring trouble equally, the AC/DC changeover switch installation position makes problems such as user's headache.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of trunking POE switch power source adapter that transmits data and galvanic ethernet network by unshielded twisted pair simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is:
The POE switch power source adapter, the RJ-45 POE port that comprise switching power circuit, is used to connect the network equipment be used to be connected the RJ-45 LAN port of importing netting twine, described RJ-45POE port and RJ-45 LAN port section corresponding terminal are electrically connected, described switching power circuit input termination power supply, output termination RJ-45 POE port.
As further improvement of the utility model, the data transfer terminal of described RJ-45 POE port and RJ-45LAN port correspondence is electrically connected.
Further improve the idle terminal of described switching power circuit output termination RJ-45 POE port as of the present utility model.
The beneficial effects of the utility model are: POE switch power source adapter of the present utility model transmits data and direct current simultaneously by unshielded twisted pair, not needing provides electric power cable separately for each network equipment, simplified installation, equipment cost and management cost have greatly been reduced, the network equipment can be installed in any position, and do not need near an already present supply socket, improved installation flexibility, in large-scale WLAN (wireless local area network) is used, only need to be equipped with a uninterrupted power supply (ups) Unity supply electric power, just can satisfy the power supply needs of all wireless ethernet network equipments, simplified network configuration, because it is a kind of trunking that adds on the basis of existing network, need not change prior network device and change existing network configuration, just can easily realize to be widely used in IP phone machine based on unshielded twisted pair transmission data by netting twine transmission data and galvanic purpose, network camera, wireless bridge, cashier's machine, secure access and monitoring system etc.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of prior wireless network;
Fig. 2 adopts wireless network architecture schematic diagram of the present utility model;
Fig. 3 adopts POE switch power source adapter structural representation of the present utility model.
Embodiment
With reference to Fig. 2, Fig. 3, POE (Power Over Ethernet) switch power source adapter, the RJ-45 POE port that comprise switching power circuit, is used to connect the network equipment be used to be connected the RJ-45 LAN port of importing netting twine, described RJ-45 POE port and RJ-45 LAN port section corresponding terminal are electrically connected, described switching power circuit input termination power supply, output termination RJ-45 POE port.
Because though unshielded twisted pair has 4 pairs of 8 heart yearns, but wherein 4 in fact in network, have only been used, be the 1st, the 2nd and the 3rd, the 6th terminal of crystal head, they play a part the sending and receiving signal respectively, and all the other 4 is that the 4th, the 5th and the 7th, the 8th terminal of crystal head is idle.The data transfer terminal the 1st, the 2nd and the 3rd, the 6th terminal of described RJ-45 POE port and RJ-45 LAN port correspondence are electrically connected.
Further improve as of the present utility model, the idle terminal of described switching power circuit output termination RJ-45 POE port, 4th, the 5th and the 7th, the 8th terminal is idle, wherein the 4th, the 5th terminal connects the switching power circuit cathode output end, and the 7th, the 8th terminal connects the switching power circuit cathode output end.
POE switch power source adapter of the present utility model transmits data and direct current simultaneously by unshielded twisted pair, not needing provides electric power cable separately for each network equipment, simplified installation, equipment cost and management cost have greatly been reduced, the network equipment can be installed in any position, and do not need near an already present supply socket, improved installation flexibility, in large-scale WLAN (wireless local area network) is used, only need to be equipped with a uninterrupted power supply (ups) Unity supply electric power, just can satisfy the power supply needs of all wireless ethernet network equipments, simplified network configuration, because it is a kind of trunking that adds on the basis of existing network, need not change prior network device and change existing network configuration, just can easily realize to be widely used in IP phone machine based on unshielded twisted pair transmission data by netting twine transmission data and galvanic purpose, network camera, wireless bridge, cashier's machine, secure access and monitoring system etc.
