发明名称 Power source isolator
摘要 A self-contained device to protect electrical appliances from damage or destruction caused by abnormal power surges due to lightening and other causes is plugged into any household electrical outlet and has a receptacle for the plug of the power cord leading to an appliance. The unitary device contains readily replaceable fuses directly in line with the appliance power line and the fuses are chosen to allow the appliance to receive the necessary power to operate while preventing it from receiving excessive damaging power. Extreme power surges due to lightening and the like are prevented from jumping the gap between the end terminals of blown fuses by following a grounding power stop clipped onto the fuse bodies near one pair of their end terminals and leading directly to a grounding conductor. The device is embodied in either a 110 v or 220 v configuration with two and three fuses respectively, and is also embodied in a television receiver protective arrangement.
