ABSTRACT:
A printed circuit board circuit tester comprising a testing head, electrical connectors carried by said head, wires and joined electrical contacts extending into said head from said connectors, the electrical contacts being fitted in a non-conducting environment supported in the head, supporting structure within the head adapted to support a circuit board to be tested, the electrical contacts extending through the non-conducting environment to a position adjacent the circuit board, apparatus operated by pressure differentials within the head for moving the circuit board into testing contact with the electrical contacts, a base on which said head is removably supported, base electrical connectors carried in said base and being adapted to mate with the electrical connectors carried in the head when said head is supported on said base, and wires and joined base electrical contacts extending from said base connectors into said base, said base electrical contacts being exposed through the base for connection to an electrical supply to test the circuit board. The base and head are removably locked together by bayonet locks in the base connectors and extending into the head connectors when they are mated. There is a lever externally of the base for locking and unlocking the bayonets.
