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.

Connector containing fusible material and having intrinsic temperature

An elongated flexible heater strip is provided having a transmission line section and a heater section employing a high mu material to control temperature at the Curie temperature of the high mu material; the above elements and a return buss being confined in a conductive sheath having a plurality of transverse slots to render the strap flexible, so that it may be cinched about a member to be heated; a strip of conductive material, such as copper, extending at least along the transmission line section interiorly of said sheath to reduce the resistance thereof and increase the current carrying capacity of the strap.
