Abstract
Abstract In a filtered connector a conductive metal tube has a barrel spring contact for receiving a mating pin and another spring contact for making electrical connection to the inside conductive surface of the pin filter. Both of the aforesaid spring contacts are formed from wall portions of the metal tube, and are therefore integral with the tube itself. A wire well at the end of the tube receives the wire which is crimped into the well. A molded plastic jacket has protruding hollow cylinders which form a jacket for the tube. The tube has an open end which receives the pins of a mating connector.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A filtering connector assembly comprising, a tubular conductive shell open at its ends and provided with insulation means therewithin, the insulation means having a longitudinally extending bore therethrough, an elongated hollow tubular filter removably held within at least one portion of the bore, an elongated tubular contact element removably mounted within the filter and conductively engaged with the inner wall thereof, the ends of the contact element being accessible at both ends of the bore within the insulation means for engagement with mating contacts, and means within the shell for grounding the outer wall of the filter to the shell.
Claim 2
Dependent Claim
100 words
A filtering connector assembly comprising, a tubular conductive shell open at its ends and provided with insulation means therewithin, the insulation means having a longitudinally extending bore therethrough, an elongated hollow tubular filter removably held within at least one portion of the bore, an elongated tubular contact element removably mounted within the filter and conductively engaged with the inner wall thereof, the ends of the contact element being accessible at both ends of the bore within the insulation means for engagement with mating contacts, and means within the shell for grounding the outer wall of the filter to the shell.
Claim 3
Dependent Claim
18 words
A filtering connector assembly according to claim 8 including means for retaining the contact element within the filter.
Claim 4
Dependent Claim
83 words
A filtering connector assembly according to claim 8 wherein the insulation means is provided with a plurality of bores therethrough, there being a said filter within each bore and a said contact element within each filter mounted in the said manner, the means within the shell for grounding the outer wall of a filter being a substantially conductive planar element extending in a plane normal to that of the filters and in direct contact with the outer wall of each of the filters.
Claim 5
Dependent Claim
46 words
A filtering connector assembly according to claim 10 and in which at least one further conductive planar element parallel to and spaced from the first planar element is in direct contact with the outer wall of each of the filters for grounding them to the shell.
Claim 6
Dependent Claim
72 words
A filtering connector assembly according to claim 8 wherein the insulator means is comprised of a pair of longitudinally spaced sections, one of said sections being removably mounted within the shell and substantially thereacross, the filter being mounted within the other insulator section with one end protruding therefrom and against the adjacent wall of the first insulator section, whereby removal of the first section permits removal of the filter from the shell.
Claim 7
Dependent Claim
56 words
A filtering connector assembly according to claim 12 wherein the insulation means is provided with an outwardly protruding insulating cylindrical member secured thereto in coaxially alignment with the bore therein, at least one end of the contact element normally extending through the insulation means and within the cylindrical member and terminating at the free end thereof.
Claim 8
Dependent Claim
17 words
A filtering connector assembly according to claim 13 wherein the cylindrical member protrudes from the first section.
Claim 9
Dependent Claim
56 words
A filtering connector assembly according to claim 8 wherein an exposed end of the insulation means within an exposed end of the insulation means within the shell is provided with a protruding insulating cylinder secured thereto and coaxial with the bore therein, the contact member extending in said cylinder and substantially terminating at its free end.
Claim 10
Dependent Claim
48 words
A filter assembly according to claim 8 in which the elongated contact member is substantially hollow, an intermediate section thereof being formed with longitudinal slits angularly spaced thereabout, the material between the slits being bowed outwardly to form spring members for engaging the inner wall of the filter.
