Abstract:
A tooling pin assembly used with a receiver in a printed circuit board tester is disclosed. The tooling pin assembly includes a locating pin with a core threaded to receive a screw, and a bushing for supporting and guiding the locating pin relative to the receiver. When the screw is rotated in one direction, the locating pin moves out of the bushing and passes through a hole in the receiver for engaging a test fixture. When the screw is rotated in the opposite direction, the locating pin retracts into the bushing until it is below the plane of the receiver. The ability to extend and retract the locating pin is especially useful when the tooling pin assembly is used with a receiver designed to hold test fixtures of various sizes.
