Wire harness assemblies are used in numerous applications, from dishwashers to fighter jets. The common expectation with any wire is that it does not become disconnected from its crimped terminal after final installation. The process of wire crimp pull testing simulates such a failure, and indicates the maximum force required for detachment.
Wire crimp pull testing can be done manually or with a motorized tester. A test stand-based manual system consists of a test stand, force gage, and grips. Such systems are flexible because different force gage ranges can be specified and interchanged, and different grip types may be easily installed. Purpose-designed manual testers integrate the force sensor, display, terminal grip, and actuator into one housing. They are generally more portable; however, the force range cannot be easily changed.
