Abstract:
A protective device for a coaxial cable having an inner conductor and an annular outer conductor, comprising:a housing;a pair of coaxial cable terminals on the housing, each of the terminals having an inner connector for electrically connecting to the inner conductor of the coaxial cable and an outer connector for electrically connecting to the outer conductor of the coaxial cable;a fuse comprising a conductive trace and a conductive layer separated by a dielectric substrate, the conductive trace being electrically connected to the inner connectors of the terminals, the conductive layer being electrically connected to the outer connectors of the terminals, the fuse forming a circuit board having a preselected capacitance for characteristic impedance matching with the coaxial cable;an outer conductive path within the housing between the outer connectors of the terminals for providing electrical continuity for the outer conductor of the coaxial cable; anda voltage protector electrically connected to the conductive trace and to a ground, the voltage protector conducting to the ground if the voltage on the inner conductor of the coaxial cable exceeds a predetermined value.
