CONNECTOR CONTAINING FUSIBLE MATERIAL AND HAVING INTRINSIC TEMPERATURE CONTROL

摘要

An electrical connector including a member, a heater element comprising a coating of ferromagnetic material on the member and a fusible material. The fusible material is melted when the ferromagnetic material is heated inductively by an alternating magnetic field. The connector can be attached to an end of a coaxial cable. The member can comprise a metal ferrule soldered around a tubular conductor of the coaxial cable and/or a central contact having a bore in one axial end thereof in which a central conductor of the coaxial cable is soldered. A dielectric coating can be provided over the coating of ferromagnetic material on the ferrule and/or central contact. The fusible material can be held in the bore in the central contact or between the dielectric coating and an electrically insulating heat-shrinkable sleeve around the ferrule. The ferrule can include one or more ports therethrough for passage of the fusible material into contact with the tubular conductor. The central contact can include one or more holes for escape of gases when the fusible material melts. To prevent shielding of the ferromagnetic material when the fusible material is located outwardly thereof, the fusible material forms a non-continuous electrically conducting path around the ferromagnetic material.
