Performance Of Cold-pressed Needles Under Light Load Conditions

As a welding-free mechanical connection method, crimp contact male is designed based on the elastic interference fit between the pin and the receiving hole, and forms a reliable electrical and mechanical connection by means of deformation within the pressing hole. The press-fit connection of crimp socket contact will generate significant elastic resistance and contact force under heavy load conditions, but this effect is sometimes not obvious under light load conditions.

Regarding the performance of female crimp contact under light load conditions, it can be understood from the physical properties of compression: when the load is low, the elastic deformation of male crimp contact is mainly used to establish initial contact. Due to the small amount of deformation, the contact pressure between the needle and the hole wall is not significantly amplified, so the displacement and force feedback caused by external load are relatively weak. At the same time, under light load conditions, factors such as assembly errors, material elastic modulus and hole diameter tolerances have a more prominent impact on the entire connection system. These micro-factors may mask the mechanical response of the press fit itself under low load conditions.
