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.

A means for terminating a bundle of glass optical fibers comprising a single plastic element and a single metal ferrule. The plastic element has four main, generally concentric, sections beginning with a nut on one end, an externally threaded portion adjacent the nut, a cylindrically-shaped portion adjacent the threaded portion but with a smaller diameter and employed to align the plastic element in a coaxial coupling means, and a small tubular portion adjacent the cylindrical portion and concentric therewith. The metal ferrule fits around the small tubular portion. An aperture having portions of decreasing diameters extends concentrically through the plastic element with the largest diameter portion being at the nut end and the smallest diameter portion being within the small tubular portion. The bundle of glass fibers with the sheath thereon extends into a first portion of the aperture, and an unsheathed portion of the bundle of glass fibers extends through a second portion of the aperture and then into the tubular portion of the plastic element which is the smallest diameter portion of the aperture. The metal ferrule is crimped over the plastic tubular element which in turn is crimped around the glass fibers to retain them in the plastic element. The end of the tubular element and the retained fibers are ground off to a predetermined distance from a reference point in the termination means so that said fibers can properly abut against a similarly terminated bundle of fibers or some other type of mating optical device.

This invention relates to a phono plug and a method of making it. An insulated disc through which extends a center contact member terminated to a center conductor of a coaxial cable is positioned in the inside surface of a U-shaped outer shell member and enclosed therein by closing the shell member into a generally cylindrical housing. An open barrel integrally attached to the shell member is either simultaneously or subsequently crimped around the braided shield on the coaxial cable to complete the phono plug.
