Connector Assembly Structure for Low-Insertion Stable Contact

The patent divides the contact point into two separate functional elements: a support contact point for bearing load and a separate mating lock portion for engagement. This segmentation allows each element to perform its specific function without the support contact point needing to provide locking force, thereby reducing insertion force while maintaining reliable lock engagement through the dedicated lock portion.

The patent introduces a resilient member as an intermediary between the contact protrusion and the mating structure. This resilient member absorbs the reaction force during engagement, reducing the insertion force required while ensuring reliable lock engagement. The intermediary element decouples the force transmission path from the locking mechanism.

The patent applies different mechanical properties to different parts of the terminal structure. The terminal body is made resiliently deformable to reduce insertion force, while the contact points and their supporting structures are designed with higher rigidity and precision to maintain positioning accuracy. This local differentiation of mechanical properties allows simultaneous achievement of low insertion force and high positioning precision.

The patent incorporates preliminary positioning features such as guide portions and predetermined positioning structures that establish accurate contact point alignment before the resilient deformation occurs during mating. This preliminary action ensures that even though the terminal deforms resiliently during engagement, the contact points maintain their designed positional relationships.
