Claim:
1. A surge protective network signal processing circuit assembly, comprising a network chip, a processing circuit and a network connector for transmitting a network signal, said network chip being electrically connected to said network connector through said processing circuit, said processing circuit comprising a plurality of two-wire channels electrically connected in parallel between respective pins of said network chip and respective contacts of said network connector and a plurality of signal coupling capacitors respectively electrically mounted in said two-wire channels; wherein said signal coupling capacitors of said processing circuit each have a capacitance value in the range of 100 μF˜0.01 μF; said processing circuit further comprises a plurality of self-coupling AC regulators respectively and electrically connected in parallel to said two-wire channel between said network connector and said signal coupling capacitors connected to lower the capacitive reactance, each said self-coupling AC regulator having a resistance value in the range of 0.1Ω˜10Ω, each said self-coupling AC regulator comprising an iron core and two windings wound round said iron core at two opposite sides, one said winding having one end thereof terminating in an input end and electrically connected to one of the two wires of the associating said two-wire channel and the opposite end thereof electrically connected with one end of the other said winding to a grounding terminal for discharging instantaneous high voltage surges caused by lightning strikes, the other said winding having an opposite end thereof terminating in an output end and electrically connected to the other of the two wires of the associating said two-wire channel.
