The Mechanism Of Symmetrical Deformation Of Transmission Lines And Contact Raw Materials In Cold-pressed Pin Riveting Connection Method

When crimp contact is locked, due to the combined effect of residual stress and deformation locking, the conductor and contact piece structure originally arranged along the axis of symmetry will undergo slight rotation, offset or deflection, causing the overall structure of crimp contact pin to deviate from its initial symmetry. Under the influence of long-term operating load, thermal expansion and vibration, this geometric and material asymmetry initially introduced by the rivet may be amplified, thus forming a continuous asymmetric deformation state between the transmission line and the contact raw material.
