Surge preventing circuit, local area network connector, and network module

A local area network connector comprising:

• a plurality of transformers, a secondary side of each of the transformers including a first terminal point, a second terminal point, and a center tapped terminal;
• a conjugate coil module having at least one first conjugate coil, the first conjugate coil having a first input terminal and a second input terminal for being coupled to the center tapped terminal of the respective transformer respectively, the first conjugate coil further having a first output terminal and a second output terminal;
• and
• a surge absorbing element having a first terminal and a second terminal, the first terminal connected to ground, the second terminal coupled to the first output terminal and the second output terminal of the first conjugate coil.

A network module comprising:

• a processing unit for controlling transfer or reception of data;
• and
• a network connector suitable for being coupled to a network and the processing unit to receive or transfer the data, the network connector including:
• a plurality of transformers, a secondary side of each of the transformers including a first terminal point, a second terminal point, and a center tapped terminal;
• a conjugate coil module having at least one first conjugate coil, the first conjugate coil having a first input terminal and a second input terminal coupled to the center tapped terminal of the respective transformer, respectively, the first conjugate coil further having a first output terminal and a second output terminal;
• and
• a surge absorbing element having a first terminal connected to ground and a second terminal coupled to the first output terminal and the second output terminal of the first conjugate coil.
