Crimping mechanism between the stranded copper wires and brass terminals was investigated in terms of repulsion force acting on crimp terminations by way of the stranded wires. The repulsion force was estimated from the load-displacement curves recorded during the crimping process. We obtained the results as follows;
(1) Repulsion forces, which were based on the elastic deformation of the strand composing wires, are observed between the stranded wires and crimp terminals.
(2) The repulsion forces have a peak value at the compression ratio of 27% in the crimp terminations.
(3) The suitable conditions of the contact resistance and the crimping strength are secured under the conditions of the peak value of the repulsion forces.
