ABSTRACT:
An extraction force tester which measures the force necessary to remove header pins from the sockets of a cable connector in a steady straight line motion, the extraction force tester includes: a base, a tensile force gauge slidably mounted to the base and a pin assembly slidably mounted in relation to the base such that the pin assembly may slide independently of the tensile force gauge. The pin assembly has a specified number of pins, e.g., twelve, for engaging the sockets of a connector. The extraction force tester further excludes a coupler for coupling the pin assembly to the tensile force gauge such that the force gauge may push the pin assembly in a first direction, to allow the pins of the pin assembly to engage the sockets of the connector, and pull the pin assembly in a second direction, opposite to the first direction, to disengage the pins from the sockets, thereby allowing the force gauge to measure the extraction force necessary to disengage the pins from the sockets.
