  • Circuit isolator
    Patent number: 4409732
    Abstract: An isolator device to electrically insulate and isolate a separate component in a circuit board arrangement to allow for relatively fast and convenient diagnostic inspection of a circuit to locate failed components. The device has an isolator sleeve with a cavity which receives the lead of the component while the lead is in situ on the board. The component lead is electrically insulated from the board circuitry to permit separate testing of the component's integrity.
