Surge Protector For Computer Equipment
US Patent:
5543999, Aug 6, 1996
Filed:
Nov 14, 1994
Appl. No.:
8/338280
Inventors:
Andrew T. Riley - Rio Rancho NM
International Classification:
H02H 322
US Classification:
361119
Abstract:
An over voltage protector for electronics equipment, such as a computer terminal, which includes first and second electrical connectors and at least one line intersecting these connectors. The protector also includes a ground which is isolated from both the connectors and the line. The line includes a resistor. The line is also connected to the protector ground via an MOV in series with a diode. With this arrangement, when a surge appears on the line the resistance on this line causes the surge to dump to ground. The diode prevents the surge from re-entering the line. The protector also includes apparatus to connect the protector ground to the building's electrical ground. This apparatus includes a grounded power cord (or grounded power cord adapter) for the equipment, a wire connected between the protector ground and the ground line of the power cord, and a capacitor and a diode connected in parallel on the ground line of the power cord for preventing any surge from entering the equipment.
