  • Peripheral device isolator
    Patent number: 6246560
    Abstract: A peripheral device isolator (32) is provided which consists of an insulating material (33) having a first conductive area (34) on a top surface and a second conductive area (35) on a bottom surface. A transient voltage suppressor (36) provides an electrical connection between the first conductive area (34) and second conductive area (35) through a first lead (38) and a second lead (40). When the peripheral device isolator (32) is placed between an internal peripheral device (12), having a common logic and chassis ground, and a host frame (10), having a host system frame ground (16), an electrical path for a voltage spike occurring on the internal peripheral device (12) is provided so that the voltage spike can be diverted away from host system logic ground (22) and into host system frame/safety ground (16).
