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 be added obtain totalResistance value 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～-XL8Resistance between any twoThe total resistance that anti-addition obtains is not equal to zero.
PTC thermistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, exceedes certain temperature (Curie's temperatureDegree) time, its resistance value is along with the rising of temperature is increasing of step evolution. PTC thermistor very low resistance value is series atPosition as shown in circuit (as Fig. 6), in the time that circuit is normally worked, electric current actual in circuit is very little, thermistor temp withRoom temperature is close, and resistance is very little, is connected in circuit, can not hinder electric current and pass through, and goes out because of lightning induction surge when circuit input endWhen existing overcurrent, thermistor is because heating power increase causes temperature rise, and resistance moment can increase severely, surge current in loopBe reduced to rapidly safety value. X in circuitL1～XL8Can not damage because power is too high Deng element.
When this circuit is embedded in crystal head, be equivalent to seal in the circuit shown in Fig. 6 in network line. With circuit L1For example, when signal code by circuit L1 along IN input through XL1Transmission, exports from circuit L1 input to circuit L1 to the back-endImpedance (the X that equals zero of endL1With-XL1It is zero that two inductive impedance are added impedance equivalence), and from circuit L1 input to other institutesThere is the inductive impedance of circuit input/output terminal and earth terminal to be not equal to zero. Therefore, when signal code passes to the back-end by circuit L1When defeated, 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 filtered 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 All other routesUpper, only can transfer to circuit L1 output, thereby guarantee that proper communication passes through circuit L1. Similarly, when signal code passes through lineRoad L2 input is held through X along INL2Transmission to the back-end, (X equals zero from circuit L2 input to the impedance of circuit L2 outputL2With-XL2It is zero that two inductive impedance are added impedance equivalences), and from circuit L2 input to other all circuit input/output terminals andThe inductive impedance of 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 to the frequency of signalImpact. When low frequency, the inductive impedance that frequency produces is very little, low frequency signal will be filtered into ground, and when high frequency because coil producesInductive impedance enough large, high-frequency signal can not be filtered into ground, can not be transferred on All other routes, only can transfer to circuit L2Output, thus guarantee that proper communication passes through circuit L2. The operation principle of circuit L3～circuit L8 is also identical with circuit L1, L2,Do not repeat them here. The spectral range overwhelming majority of the surge energy that lightning induction produces concentrates within the scope of 0～3MHz, andNormal network transmission signal but mainly concentrates on 10～1000MHZIn scope in even higher frequency range. From each lineRoad invade thunder and lightning surge energy will by this short circuit enter ground, and the normal transmission signal of high frequency will by electromagnetism exchange and toRear end conduction and signal attenuation is controlled to zone of reasonableness within. The more important thing is, because all circuits are all realized at this circuitOne point earth, guaranteed real equipotential protection effect.
