ABSTRACT:
The outer portion of a die stamped metal frame encompassing the outer ends of the electrical connecting pins is subjected to press striking for re-establishing planarity and parallelism of the opposite faces of the patterned pins which have become deformed during the die stamping, before proceeding to the assembly operations. The eventual bending of the pins of the finished product between a bending punch and a contrasting punch is performed on pins having planar and parallel faces thus preventing twisting and slanting of the bent pins.
