Abstract：

The slender arm distortion problem of connector terminal occurs usually in the high speed and precision progressive stamping.The non-uniform clearance and pressure-pad-force are regarded as the most primary and important reasons of the slender arm distortion of connector terminal.The characteristics and mechanics of centralized blanking,two-step blanking and coin process used to prevent and control the slender arm distortion problem were studied.The reasonable splitting of cutting edge shape and coin process were applied in new process scheme of some terminal to previously prevent and control the slender arm distortion problem.The analysis and application result shows that these technology methods can prevent and avoid the slender arm distortion well.
