In the defense and civilian aerospace industries, wire harnesses are liberally employed in aircraft fuselages, avionics, engines, ground support equipment, and other products. To ensure proper functioning of wire harnesses, and the safety of millions of people every day, checking the quality of crimped wire terminals is of utmost importance.
Since a common expectation with wire harnesses is that their terminals do not become disconnected after final installation, simulating a mechanical failure can be quite useful. This can be done by measuring the amount of force required to remove a terminal from a wire, generally by pulling the terminal from the wire in an axial direction.
