Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
253 words
A filtered adapter for retrofitting existing electrical connectors of known configurations to provide RFI/EMI filtering, comprising: a housing member having an overall profile matable with a known electrical eonnector and having oppositely directed mating sides, an outwardly directed flange extending from the periphery of each said mating side, said flanges being spaced substantially parallel to each other, a ground plane secured to and extending across said member substantially intermediate the mating sides thereof, said ground plane having a plurality of apertures therein each aligned with a respective terminal of said known electrical connector; a like plurality of filter sleeves each secured in a respective one of said apertures of said ground plane; a like plurality of terminals each mounted in a respective one of said filter sleeves, each said terminal having a pin configuration on a first end and socket configuration on the opposite end; a profiled shell secured to and extending outwardly from each said mating side of said housing member and providing a profile for mating with said known electrical connector; an outwardly directed flange extending from the periphery of each said profiled shell abutting against said flange of a corresponding said mating side, each said mating side flange and said shell flange thereagainst having at least one aperture therethrough in alignment with said at least one aperture of said opposite mating side and said shell flange and securing means extending through said apertures to secure said profiled shells to said housing member flanges and connect said ground plane to ground.

Claim 3
Dependent Claim
42 words
A filtered adapter according to claim 1 further comprising: potting material substantially filling said housing member to at least the mating side on one side of the ground plane and into the profiled shell on the other side of the ground plane.
Claim 4
Dependent Claim
54 words
A filtered adapter according to claim 1 further comprising: an insert of insulation material substantially filling said housing to at least the mating side on one side of the ground plane, and a second insert of insulation material substantially filling the housing from the other side of said ground plane into said profiled shell.
Claim 5
Dependent Claim
25 words
A filtered adapter according to claim 1 further comprising: an insulative coating material applied to said filter sleeves and ground plane on both sides thereof.
Claim 6
Dependent Claim
16 words
A filtered adapter according to claim 1 wherein said housing member has a generally rectangular configuration.
Claim 7
Dependent Claim
15 words
A filtered adapter according to claim 1 wherein said housing member has a circular configuration.
Claim 8
Dependent Claim
18 words
A filtered adapter according to claim 1 further comprising: means to latchingly secure said connector to said adapter.
Claim 9
Dependent Claim
227 words
An electrical connector comprising: a housing formed of a central shell with outwardly peripherial flanges forming oppositely directed mating faces, and two end shells each having an outwardly directed flange portion which overlies a flange of the central shell and an axially directed hood portion shaped to mate with a respective matable connector member and means to secure said flange portions of said end shells to the respective flanges of said central shell; an apertured electrically conductive ground plane member secured within the housing; means to connect said ground plane member to ground; a plurality of tubular filter members each having isolated electrodes on their inner and outer surfaces, each filter member being secured in an individual aperture in the ground plane member with the outer surface electrode of the filter member in electrical contact with the ground plane member; a plurality of electrical terminals each passing through an individual one of the filter members in electrical contact with the inner surface electrode of the filter member, each terminal having two oppositely directed matable contact portions; and electrical insulative material filling said central shell on both sides of said ground plane member at least to said flanges encapsulating said filter members therein, whereby the connector can be interposed between a pair of matable electrical connectors to provide filtering on electrical circuits passing through the matable electrical connectors.
