Abstract
The utility model discloses an anti-surge filter circuit and a connector using the circuit. The anti-surge filter circuit comprises a first side and a second side characterized by full duplex transmission. A plurality of transmission channels are arranged between the first side and the second side. Each transmission channel is provided with a transformer and a common-mode choke coil connected with the transformer. A resistor is connected on the first tap of each transformer and further connected with a grounding point through an anti-surge module. The anti-surge module comprises a first capacitor and a surge inhibition thyristor which are in parallel connection. Resistors are connected on the first taps of the transformers. A Bob-Smith circuit is thus formed. Impedance match is achieved between the circuit and an external-connection network cable. Signal loss during a transmission process can be alleviated. Better filtering effects are also achieved. Excellent network consistency can be further realized. After being connected with the resistors, the first taps are connected with the grounding point through the anti-surge module. The circuit line is enabled to bear relatively high voltages to the ground. The circuit has great surge protection effects.
