Abstract
Abstract Modular electrical connector assemblies and filtered connector inserts therefor. The assembly includes one or more filtered connector inserts releasably mounted within an outer conductive shell. A plurality of filtered contact assemblies are releasably retained within the insert. Each filtered contact assembly includes an electrical contact, a filter electrically coupled to the contact, and a first grounding means electrically coupled to said filter. The filtered contact assemblies are releasably and electrically coupled to the insert when the assemblies are releasably mounted to the insert, and to the outer shell when the insert is mounted within the shell. With the invention, a grounding path is automatically provided from the filter associated with each filtered contact assembly to the outer shell to dissipate filtered interference, while allowing individual removal and replacement of each filtered contact assembly from the insert, and removal and replacement of each insert from the shell. The filtered inserts have the same dimensions and contact placement as their corresponding unfiltered inserts, and are fully interchangeable therewith.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
243 words
An electrical connector assembly comprising: an electrically conductive shell, said shell including at least one insert-receiving aperture; a filtered connector insert positioned within said insert-receiving aperture, said insert including; a housing; at least one filtered contact assembly within said housing, each filtered contact assembly including an electrical contact and filter means electrically coupled to said contact; means for defining a grounding plane electrically coupling said filter means to said shell for providing a grounding path from said filter means to said shell for dissipating filtered interference, said means for defining said ground plane including first grounding means on each filtered contact assembly, an electrically conductive eyelet surrounding said filter means, and second grounding means on said housing comprising an electrically conductive ground plate in said housing; respective means associated with each filtered contact for releasably retaining each filtered contact assembly within said housing, said retaining means comprising spring finger means on said filtered contact assembly, and an internal shoulder in said aperture in said housing said spring finger means being integral with and extending from said eyelet and engaging said shoulder upon insertion at said filtered contact assembly into said aperture to oppose the withdrawal of said filtered contact assembly, said spring finger means further comprising first coupling means for releasably electrically coupling said eyelet of said filter means to said second grounding means when said filtered contact assembly is in said housing; and means for releasably mounting said insert within said shell.
Claim 2
Dependent Claim
243 words
An electrical connector assembly comprising: an electrically conductive shell, said shell including at least one insert-receiving aperture; a filtered connector insert positioned within said insert-receiving aperture, said insert including; a housing; at least one filtered contact assembly within said housing, each filtered contact assembly including an electrical contact and filter means electrically coupled to said contact; means for defining a grounding plane electrically coupling said filter means to said shell for providing a grounding path from said filter means to said shell for dissipating filtered interference, said means for defining said ground plane including first grounding means on each filtered contact assembly, an electrically conductive eyelet surrounding said filter means, and second grounding means on said housing comprising an electrically conductive ground plate in said housing; respective means associated with each filtered contact for releasably retaining each filtered contact assembly within said housing, said retaining means comprising spring finger means on said filtered contact assembly, and an internal shoulder in said aperture in said housing said spring finger means being integral with and extending from said eyelet and engaging said shoulder upon insertion at said filtered contact assembly into said aperture to oppose the withdrawal of said filtered contact assembly, said spring finger means further comprising first coupling means for releasably electrically coupling said eyelet of said filter means to said second grounding means when said filtered contact assembly is in said housing; and means for releasably mounting said insert within said shell.
