Further illustrate, as shown in Figure 6, in the functional circuit (10) of described functional module (3), comprise circuit L1～L8,Inductive impedance XL1～XL8 (6011～6018) ,-XL1～-XL8 (6021～6028), thermistor PTC (6031); Circuit L1-L8Connect respectively eight heart yearns of crystal head lambda line cable; XL1(6011)～XL8(6018)、-XL1(6021)、～-XL8(6028) respectivelyBe inductive impedance, PTC is thermistor (6031). XL1(6011)～XL8(6018) be connected in parallel each other, and and macromoleculePTC thermistor (6031) is connected in series rear ground connection.-XL1(6021)、～-XL8(6028) be also connected in parallel each other, and with heightMolecule PTC thermistor (6031) is connected in series. The input of circuit L1 and XL1Be connected, the output of circuit L1 and-XL1Be connected; The input of circuit L2 and XL2Be connected, the output of circuit L2 and-XL2Be connected; The input of circuit L3 and XL3Be connected, the output of circuit L3 and-XL3Be connected; The input of circuit L4 and XL4Be connected, the output of circuit L4 and-XL4Be connected; The input of circuit L5 and XL5Be connected, the output of circuit L5 and-XL5Be connected; The input of circuit L6 and XL6Be connected, the output of circuit L6 and-XL6Be connected; The input of circuit L7 and XL7Be connected, the output of circuit L7 and-XL7Be connected; The input of circuit L8 and XL8Be connected, the output of circuit L8 and-XL8Be connected; Wherein, inductive impedance value modelEnclose 10～200 microhenrys; Thermistor span 0.05 Europe, Europe～10; Preferably, inductive impedance span 25 microhenrys～35 microhenrys; Thermistor span 0.1 Europe, Europe～0.5.
Wherein inductive impedance XL1And inductive impedance-X (6011)L1(6021) both by two groups of coils that share same high frequency magnetic core aroundSystem forms, inductive impedance XL1And inductive impedance-X (6011)L1(6021) numerical value equates and coil winding opposite direction, therefore XL1With-XL1It is zero that two inductive impedance are added the total resistance obtaining. Similarly, XL2With-XL2、XL3With-XL3、XL4With-XL4、 XL5With-XL5、XL6With-XL6、XL7With-XL7、XL8With-XL8Share respectively same high frequency magnetic core two groups of coil windings andBecome, coil can adopt copper conductor also can adopt other plain conductor coilings, also can draw at pcb board, thus XL2With-XL2、XL3With-XL3、XL4With-XL4、XL5With-XL5、XL6With-XL6、XL7With-XL7、XL8With-XL8Inductive impedance phaseAdding the total resistance obtaining is zero. But due to XL1With XL2～XL8In arbitrary all not coilings on same high frequency magnetic core, similarly,XL1With-XL2～-XL8In arbitrary also not coiling on same high frequency magnetic core, therefore XL1With XL2～XL8And XL1With-XL2～-XL8Impedance is between any two added the total resistance obtaining and is not equal to zero.
PTC thermistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, exceedes certain temperature (Curie temperature)Time, its resistance value is along with the rising of temperature is increasing of step evolution. PTC thermistor very low resistance value is series to circuitPosition as shown in (as Fig. 6), in the time that circuit is normally worked, electric current actual in circuit is very little, thermistor temp and chamberTemperature is close, and resistance is very little, is connected on and in circuit, can hinder electric current and pass through, and occur because of lightning induction surge when circuit input endWhen overcurrent, thermistor is because heating power increase causes temperature rise, and resistance moment can increase severely, and in loop, surge current is fastSpeed is reduced to safety value, and the inductive impedance element in circuit can not damaged because power is too high.
When this circuit is embedded in network interface converter, be equivalent to seal in the circuit shown in Fig. 6 in network line. With lineRoad L1 is example, when signal code by circuit L1 along IN input through XL1Transmission to the back-end, from circuit L1 input to lineThe impedance of the road L1 output (X that equals zeroL1With-XL1It is zero that two inductive impedance are added impedance equivalence), and input from circuit L1End is not equal to zero to the inductive impedance of other all circuit input/output terminals and earth terminal. Therefore, when signal code is by circuit L1While transmission to the back-end, the frequency influence of signal will be subject to. When low frequency, the inductive impedance that frequency produces is very little, and low frequency signal will be by mistakeFilter into ground, and the inductive impedance producing because of coil when high frequency is enough large, high-frequency signal can not be filtered into ground, can not be transferred to itOn his circuit, only can transfer to circuit L1 output, thereby guarantee that proper communication passes through circuit L1. Similarly, when signal electricityStream is held through X along IN by circuit L2 inputL2Transmission to the back-end, the impedance from circuit L2 input to circuit L2 output(X equals zeroL2With-XL2It is zero that two inductive impedance are added impedance equivalence), and from circuit L2 input to other all circuitsThe inductive impedance of input/output terminal and earth terminal is not equal to zero. Therefore, in the time that transmitting to the back-end by circuit L2, signal code will be subject toThe frequency influence of signal. When low frequency, the inductive impedance that frequency produces is very little, low frequency signal will be filtered into ground, and when high frequencyThe inductive impedance producing because of coil is enough large, and high-frequency signal can not be filtered into ground, can not be transferred on All other routes, only can passTransport to circuit L2 output, thereby guarantee that proper communication passes through circuit L2. The operation principle of circuit L3～circuit L8 also with circuitL1, L2 are identical, do not repeat them here. The spectral range overwhelming majority of the surge energy that lightning induction produces concentrates on 0～3MHzIn scope, and normal network transmission signal mainly concentrates in frequency range even higher within the scope of 10～1000MHZ.The thunder and lightning surge energy of invading from each circuit will be entered ground by this short circuit, and the normal transmission signal of high frequency will be handed over by electromagnetismChange and to the back-end conduction and signal attenuation is controlled to zone of reasonableness within.
