Headroom is an evaluation of crimp force with and without copper strands in the conductor crimp. Twenty good crimps are made and the average peak force is calculated. Ten crimps are made without copper strands in the conductor crimp (insulation crimp only) and the average peak force is calculated. The difference in peak force with and without copper strands in the conductor crimp is headroom. If the headroom value is divided by the number of copper strands it can be estimated the force per wire strand. With this value the performance of the Crimp Force Monitor (CFM) can be predicted, how many strand out can be detected. |
