Patent ID: 7193837

Claim:
A plug comprising: A) a connection element which is connected to a ground system having a stray inductance when in use; B) a plug housing; C) a contact element which is electrically connected to an electrostatic discharge conducting contact element which is in contact with a person who is carrying electrostatic charge and who is to be protected from effects associated with electrostatic discharge when said contact element is in use, the discharge of such electrostatic charge containing all frequencies associated with such discharge, the contact element having a resistance in series therewith and assuming an electric potential that is associated with the electrostatic charge on the person when the person touches the contact element; and D) an inductor element electrically interposed in series between said contact element and the ground system so that electric current associated with the electric potential on the contact element must flow through the inductor element to reach the ground system, the inductor element being electrically connected to the ground system at a connection location, said inductor element having an inductance which is greater than the stray inductance of the ground system at the connection location between said inductor element and the ground system, the electric current associated with the electrostatic charge containing all frequencies associated with the electrostatic discharge.
