How Does The Riveting Method Enable Cold-pressed Pins To Achieve Better Impact Toughness?

In this riveting connection method, the rivet, in a cold state, is tightly bonded to the crimp socket contact component through compression, deformation, or pressing into the workpiece, thereby reducing loosening of the connection interface and the propagation of microcracks.

In the female crimp contact structure, the riveting connection method also improves stress distribution: the rivet itself bears part of the impact load, while the plastic locking effect delays crack initiation in the connection area, thus achieving higher impact toughness.

In practice, attention should be paid to rivet material matching, hole diameter accuracy, and the fit clearance between the male crimp contact and the bearing plate. It has been found in practice that if the fit between the rivet and the connecting hole is too loose, it will weaken the plastic deformation capacity of the connection area.
