Abstract

While servicing reprographic equipment and other office equipment sensitive to electrostatic discharge (ESD), there is a need to maintain an earth ground path during servicing. More specifically, when the equipment power cord is unplugged from the wall outlet for safety reasons, the earth ground path is also lost, thereby increasing the potential for ESD damage to electrical components.

ELECTROSTATIC DISCHARGE EARTH GROUND PATH TOOL( Cont'd)

While servicing reprographic equipment and other office equipment sensitive to electrostatic discharge (ESD), there is a need to maintain an earth ground path during servicing. More specifically, when the equipment power cord is unplugged from the wall outlet for safety reasons, the earth ground path is also lost, thereby increasing the potential for ESD damage to electrical components.

Accordingly, the present invention was developed as an effective, low cost device to enable the service representative to utilize the earth ground path normally present during operation of the machine, without risk of contact with the AC power source. As shown in the figure, ground path tool 10 is intended to be attached to ground terminal 12 of power cord 14 and subsequently plugged into the ground terminal of a wall receptacle, thereby establishing an earth ground path. Ground path tool 10 is a brass jumper plug, with a male lug, 16, designed to fit within the ground terminal of a 110 volt AC outlet. On the other end, tool 10 has a female receptacle, 18, for receipt of the ground terminal 12 found on all grounded office equipment powe...
