Technical field
The utility model belongs to network filtering technical field, is specifically related to a kind of Ethernet filter.
Background technology
Ethernet is current most popular local area network technology; Because it is simple, cost is low, extensibility by force with the feature such as IP network can be combined well, the application of ethernet technology just strides forward from Intranet to public telecommunication network field.10G ethernet technology breaches the restriction of traditional ethernet short range transmission.Except being applied in local area network (LAN) and Campus Networks, also can being applied in metropolitan area even wide scope easily, building high performance network core.Adopt ten thousand mbit ethernet links can improve network cost performance and simplified network at metropolitan area network backbone layer.Break through the Main Bottleneck of 10G in each macroreticular company after, advance with unprecedented speed after 10G system is certain.Therefore the network filter that exploitation is applicable to 10GBASE-T ethernet communication field is imminent.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provide a kind of Ethernet filter, it has better coupling performance, and the data volume that the unit interval transmits is large, can meet the requirement of 10GBase-T.
The technical scheme that the utility model adopts is: a kind of Ethernet filter, comprise glue shell, also comprise and organize inductance coil more, described inductance coil comprises main magnetic core, secondary magnetic core and the twistedwire be wrapped in main magnetic core and secondary magnetic core, described twistedwire is by 8 enamelled wires, two is one group of totally 4 groups of Stagger-wrap composition, twistedwire is peripheral around described main magnetic core, and twistedwire have two groups of enamelled wires extend stranded after around in secondary magnetic core, wherein often organize inductance coil and be provided with 6 lead-in wire links, two terminations of 4 terminations of 4 groups of enamelled wires and two groups of enamelled wires extended link that goes between with is respectively connected, described lead-in wire link is positioned at glue shell both sides, and with the conducting of pin pin, the groove that many groups match with inductance coil is provided with in described glue shell.
As preferably, same group of enamelled wire of described twistedwire is same color, and is provided with a binding post.
As preferably, described twistedwire has 4 groups of different colors, and often organizes color and be respectively equipped with a binding post.
As preferably, described 6 the lead-in wire links often organizing inductance coil are evenly distributed on glue shell both sides.
The beneficial effects of the utility model are: the utility model adopts many line combinations to implant main magnetic core and secondary magnetic core, make it have better coupling performance, the data volume transmitted in the unit interval is large, the width of data pulse voltage signal becomes narrower, require that the additional rise time (or fall time) that network transformer brings is shorter, and make its electric property can meet the requirement of 10GBase-T.

Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment: as Fig. 1, shown in Fig. 2 and Fig. 3, the utility model comprises glue shell 1, also comprise and organize inductance coil more, described inductance coil comprises main magnetic core 2, secondary magnetic core 3 and the twistedwire 4 be wrapped in main magnetic core 2 and secondary magnetic core 3, described twistedwire 4 is by 8 enamelled wires 5, two is one group of totally 4 groups of Stagger-wrap composition, the same group of enamelled wire 5 of twistedwire 4 is same color, and be provided with a binding post, 4 groups of enamelled wires 5 are provided with 4 kinds of different colors, often organize color and be respectively equipped with a binding post, described twistedwire 4 is peripheral around described main magnetic core 2, and twistedwire 4 have two groups of enamelled wires 5 extend stranded after around in secondary magnetic core 3, wherein often organize inductance coil and be provided with 6 lead-in wire links 6, 6 lead-in wire links 6 are evenly distributed on glue shell 1 both sides, two terminations of 4 terminations of 4 groups of enamelled wires 5 and two groups of enamelled wires 5 extended link 6 that goes between with is respectively connected, described lead-in wire link 6 is positioned at glue shell 1 both sides, and with pin pin 7 conducting, the groove that many groups match with inductance coil is provided with in described glue shell 1.
Main magnetic core 2 of the present utility model uses twistedwire 4 repeatedly to penetrate in main magnetic core 2 hole, reach satisfied electrical requirement, and then get do not penetrate part remaining line carry out stranded, when stranded rear implantation secondary magnetic core 3 filter bipod adds signal voltage (difference mode signal), the secondary end acting on filter through flux coupled induces induced potential.For signal voltage, the signal code equal and opposite in direction simultaneously flow through due to CMC two winding, direction are contrary, create the magnetic flux that direction is contrary, cancel out each other, do not affect differential mode signal transmission in the iron circuit of CMC.What now CMT two winding flow through is then equal and opposite in direction, the electric current that direction is identical, causes the effect of CMT to be equivalent to a large resistance, hinders passing through of difference mode signal, few on the transmission impact of carrier signal, is added in load so difference mode signal is directly coupled.And concerning common-mode signal, mainly be coupled to secondary by the distributed capacitance of primary and secondary of filter, and now CMC two winding flows through is the identical electric current in equal and opposite in direction, direction, at this moment CMC is equivalent to a large resistance, stop the transmission of common mode current, CMT two winding is then flow through the contrary electric current in equal and opposite in direction, direction, is equivalent to short circuit to common-mode signal, such common-mode voltage is substantially gone up and can not be transmitted, and is coupled in load.Thus carrier signal can be made well to be transmitted, can common mode interference signal be suppressed again.
The utility model adopts many line combinations to implant main magnetic core 2 and secondary magnetic core 3, make it have better coupling performance, the data volume transmitted in the unit interval is large, the width of data pulse voltage signal becomes narrower, require that the additional rise time (or fall time) that network transformer brings is shorter, and make its electric property can meet the requirement of 10GBase-T.
