Modular connector assembly and filtered insert therefor

Abstract

Modular electrical connector assemblies and filtered connector inserts therefor. The assembly includes one or more connector inserts removably mounted within an outer shell. The filtered insert comprises a housing means, at least a portion of which is electrically conductive; at least one electrical contact within the housing means; and filter means within the housing electrically coupled to the contact for filtering interference, and electrically coupled to the conductive housing portion for providing a grounding path from the filter means to the conductive housing portion. Means are also provided for electrically coupling the conductive housing portion of the insert to the outer shell automatically when the insert is positioned in and mounted to the shell to provide an external grounding path from the conductive housing portion to the shell. With the invention connection of the grounding plane of the insert to external ground is achieved automatically upon mounting of the insert to the shell without requiring a solder connection and without using complex mounting springs or grounding clips, thus retaining the ability to easily mount and remove the filtered insert from the shell. The filtered insert preferably also has the same dimensions and contact placement as its corresponding unfiltered insert, and is fully interchangeable therewith.
