COAXIAL CONNECTOR AND PRODUCTION METHOD THEREFOR AND SUPERCONDUCTING DEVICE

摘要

A coaxial connector (10) for connection with a coaxial cable comprising a surface film layer (20) consisting of In or In alloy and formed on the surface of a terminal (12) as a central conductor. Since In similar to an In solder material is used as the material of the surface film layer, a reactive product is prevented from being produced in In solder by the reaction between the surface film layer material and the In solder material. Accordingly, the flexibility of the In solder can be retained, and a superconducting device that survives repeated temperature changes between room temperature and low temperatures can be provided.
