Abstract
A terminal crimping device includes crimp tooling including an anvil and a ram movable toward the anvil with a crimp zone being defined between the anvil and the ram configured to receive a wire and a terminal configured to be crimped to the wire by the crimp tooling. An ultrasonic transducer is coupled to at least one of the anvil and the ram that receives acoustic signals sent through the wire and terminal. A crimp quality module receives signals from the ultrasonic transducer. The crimp quality module determines a crimp height of the terminal based on the acoustic signal received by the ultrasonic transducer. Optionally, the crimp height may be determined based upon a transmission time of the acoustic signal from a transmitting transducer to a receiving transducer. The crimp height may be determined based upon a speed of sound transmission coefficient of the terminal and the wire.
