ABSTRACT:
A filtered adapter assembly is disclosed for retrofitting electronic filtering elements between matable coaxial connector units, and comprises a contact sub-assembly, tubular adapting means including an adapter shell, a conductive retention ring, and a pair of dielectric inserts. The contact sub-assembly includes a ceramic filter sleeve having a pin extending therethrough and a flanged collar around the filter sleeve. The adapter shell is provided with a step profiled throughbore receiving the contact sub-assembly therein with clearance, and the retention ring is press-fit into the bore against the collar flange to secure the sub-assembly within the bore, and to electrically common the sub-assembly filter sleeve and the adapter shell. The dielectricinserts are subsequently inserted into the adapter shell with alternate ends of the sub-assembly pin extending therethrough to insulate the pin from the adapter shell.
