Solderless filter mounting for header assemblies

A filtered header or feedthrough connector for retrofitting existing electronic circuitry to provide RFI/EMI filtering, comprising:

• a ground plane having a plurality of bores therein;
• a pair of mating housing members together defining a cavity therebetween, a plurality of terminal bores extending through said members and entering said cavity in a spaced array;
• a plurality of filter-terminal assemblies each including a filter sleeve secured intermediate the ends of an elongated terminal,
• a mounting system including a rubber block mounted in the cavity portion of each said housing member, a plurality of apertures in each said block each aligned with a respective terminal bore in said array, a conductive rubber gasket mounted between the rubber block of one of said housing members and said ground plane, said gasket having an array of apertures aligned with those of said blocks and said housings and sized to form an interference fit with said filter sleeves,
• whereby said filter-terminal assemblies are held in said housings with limited float for self alignment and with electrical contact with said ground plane being provided by said gasket.

In a filtered header or feedthrough connector means to provide solderless mounting of RFI/EMI filtering, comprising:

• a ground plane having a plurality of apertures therein each aligned with a respective terminal of a known electrical connector;
• a pair of hermaphroditic housing members each having oppositely directed mating sides, the first of which has an overall profile matable with said known electrical connector and the second of which is substantially planar with a cavity formed therein;
• a rubber block mounted in each said cavity;
• a conductive rubber gasket mounted between at least one rubber block and said ground plane;
• a like plurality of filter sleeves each passing through 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 opposite ends projecting from said housing members;
• and
• means to mount said housing members so as to apply compression to said blocks.

A filtered connector comprising:

• a ground plane having an array of apertures therein;
• a pair of identical housing members each having oppositely directed mating and filter cavities, a plurality of apertures in a spaced array interconnecting the cavities of each housing member, said housing members being adapted to be mounted on opposite sides of said ground plane with said filter cavities towards said ground plane and said arrays of apertures in alignment;
• a first rubber block mounted in the filter cavity of one of said housings and a second similar rubber block received in the filter cavity of the other of said housing members with a conductive rubber gasket interposed between said second rubber block and said ground plane, said blocks and gasket having an array of bores aligned with the apertures in said housing members and said ground plane;
• and
• a plurality of filtered terminals,
• whereby when said housing members are assembled with said ground plane, said rubber blocks and rubber gasket are under compression placing the gasket into electrical contact with said filters and said ground plane.
