Inspection Socket Contact Pin With Casing-Bypass Heat and Current Paths

The contact pin is divided into multiple contacts (first contact, second contact, third contact) that are laterally stacked and bundled by a casing. Each contact has an elastic deformation part, allowing independent elastic deformation while maintaining overall structural integrity. This segmentation enables improved electrical and thermal performance through multiple parallel contact paths while managing complexity through modular design.

The patent transitions from a conventional linear/contact-series arrangement to a lateral stacking configuration where multiple contacts are arranged side-by-side in the lateral dimension. The casing bundles these laterally stacked contacts, creating a three-dimensional structure that improves electrical and thermal performance by providing multiple parallel conduction paths without increasing the vertical profile excessively.

The casing is designed to contact the base ends of the contacts rather than the elastic deformation parts. This extraction of the contact point from the complex elastic deformation region to the simpler base end region improves electrical and thermal conductivity by establishing direct contact paths through the casing, while still allowing the elastic deformation parts to function independently for mechanical compliance.

The casing acts as an intermediary structure that bundles the laterally stacked contacts and provides a common mounting interface. By contacting the base ends of multiple contacts simultaneously, the casing serves as a mediator that transfers electrical and thermal energy efficiently to all contacts without requiring direct contact with each individual elastic deformation part, thus simplifying the overall structure while maintaining high conductivity.
