Abstract
This disclosure relates to an EMI (Electro Magnetic Interference) filter connector which can be installed in the line between mating plugs and sockets normally used for terminating multiple conductors. This connector is used in an electronic equipment chassis or at a bulkhead junction box or, if necessary, between mating connectors in a cable run, where the metallic parts of the cable connector can be grounded. Conductive rubber or co-polymer elastometric washers are used to protect RF filter components in the connector from damage due to external stress. A high degree of EMI attenuation is provided by an integral metallic baffle having close fitting conductor holes which is located within the connector body.
Claims6
An electrical connector assembly capable of attenuating electromagnetic and radio frequency interference comprising:
- an electrically conductive shell including a generally transverse ground plate formed integrally therewith;
- at least one elongated electrical contact member extending longitudinally within said shell and through an aperture in said ground plate;
- a filter assembly associated with said contact member including means mounted coaxially over said contact member and also extending through said aperture for providing a series inductance for said filter assembly, capacitor means mounted coaxially over said inductance means on opposite sides of said ground plate, and electrically conductive first elastomeric grommet means disposed at opposite ends of said filter assembly and second elastomeric grommet means interposed between said capactor means and said ground plate;
- and
- two dielectric inserts, each retained within said shell on an opposite side of said ground plate and including at least one cavity for receiving and supporting said contact member and its associated filter assembly, said insert cavity having a length such that said grommet means are axially compressed to resiliently support said filter assembly.
