Electromagnetic shielding assembly, electromagnetic interference and lightning protection module and power supply

An electromagnetic interference and lightning protection module adapted for a power supply, the electromagnetic interference and lightning protection module comprising:

• an electromagnetic interference shielding component comprising:
• a plate body;
• a bending portion, an included angle being formed between the plate body and the bending portion, and the plate body and the bending portion cooperatively covering an input socket of the power supply;
• at least one grounding pin disposed on at least one of the plate body and the bending portion and configured to ground with and screw to a housing of the power supply;
• and
• a welding pin disposed on a side of the bending portion away from the plate body and configured to electrically connect to an end of an auxiliary circuit board;
• and
• a lightning protection circuit comprising at least one surge absorber electrically connected to another end of the auxiliary circuit board and located in a position corresponding to an axis of a fan of the power supply, and the electromagnetic interference shielding component and the at least one surge absorber being disposed at a same side of the auxiliary circuit board.

A power supply comprising:

• a housing comprising an upper casing and a lower casing combined with each other;
• a main circuit board disposed on the lower casing;
• a fan disposed on the lower casing and adjacent to the main circuit board;
• an input socket disposed on an end of the lower casing and spaced from the fan;
• and
• an electromagnetic interference and lightning protection module comprising:
• an electromagnetic interference shielding component comprising:
• a plate body;
• a bending portion, an included angle being formed between the plate body and the bending portion, and the plate body and the bending portion cooperatively covering the input socket;
• at least one grounding pin disposed on at least one of the plate body and the bending portion and configured to ground with and screw to the housing;
• and
• a welding pin disposed on a side of the bending portion away from the plate body and configured to electrically connect to an end of an auxiliary circuit board;
• and
• a lightning protection circuit comprising at least one surge absorber electrically connected to another end of the auxiliary circuit board and located in a position corresponding to an axis of the fan, and the electromagnetic interference shielding component and the at least one surge absorber being disposed at a same side of the auxiliary circuit board;
• wherein the auxiliary circuit board is disposed between the housing and the input socket and perpendicular to the main circuit board, and the at least one surge absorber is disposed between the input socket and the fan.
