Patent ID: 7204695

Claim:
A fastener structure comprising a connector plug and a connector socket; a protruding connecting portion is formed on one side of the connector plug, and a plurality of aligned terminals and fool-proof fasteners are configured on the protruding connecting portion; a passive electromagnetic member and electric conducting spring pieces are configured between the plurality of aligned terminals and the protruding connecting portion; the electric conducting spring pieces are correspondingly connected to positive and negative poles of a power cable, and the positive and negative poles of the power cable and a transformer are correspondingly connected to butt spring pieces protruding from two sides of the protruding connecting portion; the butt spring pieces are correspondingly fitted into a fixing slot of the connector socket, when the protruding connecting portion is plugged into the fixing slot, the butt spring pieces of the protruding connecting portion make contact with the electric conducing spring pieces, thereby enabling the passive electromagnetic member to produce a magnetic effect that achieves the objective of magnetic joining of the connector plug and the connector socket and electrical connection to a power supply.
