Abstract
An electromagnetic shield is disclosed for use in combination with a standard connector to provide electromagnetic compatibility for the connector system. The shield includes a two part enclosure for a plug member, which enclosure is attached to the braided shielding of a cable and which requires no gasketing to provide complete shielding. A shroud is provided for a receptacle member and the two shields interfit in such manner as to obviate the need for further gasketing at the mating interface.
Claims11
In combination with an electrical connector having mating first and second members, a kit providing electromagnetic shielding for said connectors, said kit comprising:
- a first enclosure formed by an intermating metallic inner first shell and outer second shells, said shell defining therebetween a cavity adapted to receive one of said connector members therein, each shell having a tail portion adapted to be received within a braided layer of shielded cable said inner first shell having a plurality of cantilever beams extending from a substantial portion of the periphery thereof and having an outwardly directed dimple spaced from the free end of each beam, said outer second shell having a flange depending from a like portion of the periphery thereof and adapted to receive said beams therein in interference fit, said flange also having an array of apertures spaced to each receive a respective dimple to secure said shells together,
- clamp means adapted to embrace said cable bringing said braided layer into good mechanical and electrical contact with said tail portions, and
- a second enclosure formed by a metallic shroud adapted to substantially enclose said second member and engage shielding associated therewith and the metallic shells of said first enclosure.
Means to provide electromagnetic shielding to a conventional electrical connector having two mating pieces, said means comprising:
- a first metallic enclosure for a first one of said connector members, said first enclosure having mating inner and outer shell members each with semi-cylindrical tail portions adapted to be received within a shielding portion of a shielded cable said inner shell having a plurality of cantilever beams about a substantial portion of the periphery thereof, each beam having an outwardly directed dimple adjacent the free end thereof, said outer shell having a flange depending from a substantial portion of the periphery thereof with a like plurality of apertures each spaced to receive a respective dimple therein to hold said shells together,
- clamp means adapted to apply compressive force to said cable creating good electrical and mechanical connection between a cable shielding portion and said tail portions;
- and
- a second metallic enclosure adapted to enclose a second one of said connector members therein and to receive said first member and first enclosure in mating relationship, said second enclosure engaging shielding associated with said second member as well as said first enclosure.
