Abstract:
A protective device for deflecting or reducing short duration, large current electromagnetic impulses traveling along an RF cable while allowing desired RF signals to pass through comprising:(a) an outer conductor, said outer conductor comprising a main body section, a first connector and a second connector, said main body section having a first end and a second end, said first connector extending out from the first end of the main body section, said main body section being in the form of a housing having an inner sidewall that is cylindrically shaped, said second connector extending out from the second end of the main body section, (b) an inner conductor axially disposed within the outer conductor and extending through said main body section into said first and second connectors, (c) insulators for mechanically supporting and electrically insulating the inner conductor from the outer conductor, (d) protective element disposed inside the main body section between the inner sidewall in the main body section and the inner conductor, and (e) a spring of electrically conductive material disposed inside the main body section between the inner sidewall and the protective element, said spring being in contact with said inner side wall of said housing and said protective element and being under compression.
