ABSTRACT:
The present invention is directed to the determination of the force imposed on a terminal being crimped onto a wire. The crimping mechanism includes a cantilevered member which is deflected an amount that is proportional to the crimping force imposed on the terminal by the crimping bar. The amount of this deflection is sensed by four strain gages which are coupled to the cantilevered member and are electrically interconnected to form a Wheatstone bridge. The output of the Wheatstone bridge is then translated into actual force being imposed upon the terminal.
