Abstract
An EMI transfer fitting suitable for use in submarines and other harsh environments is provided. In one embodiment, the EMI transfer fitting has two couplers, that collectively provide a mechanically robust interconnection between a flexible conduit (through which a bundle of data cables is encased by a wire mesh sheath that provides EMI shielding), and a rigid conduit made from a metallic material that requires no separate wire mesh sheath to provide EMI shielding. In addition to providing a robust mechanical interconnection, the transfer fitting provides a robust and seamless EMI shielding between the flexible conduit and the rigid conduit.
Claims13
An EMI transfer fitting comprising:
- a first coupler for connection to an unthreaded rigid conduit for carrying a cable bundle, said first coupler having a first male fastener, a compression ring and a first female fastener for receiving said conduit therethrough, one of said fasteners being at a distal end adjacent to said rigid conduit and the other of said fasteners being at a proximal end opposite said distal end, said first male fastener and said first female fastener having a first cooperating tightening means for urging said first male fastener towards said female fastener, such that when said first male and female fasteners are tightened, said compression ring has external pressure applied thereto thereby securely grasping said conduit within said first coupler;
- and
- a second coupler attached to said proximal end, said second coupler having an attachment means for connecting to a flexible conduit for carrying a sheathed cable therein, said second coupler further having a second male fastener, a hollow insert for passing said cable therethrough and passing said sheath thereover, and a second female fastener, said second male fastener and said second female fastener having a second cooperating tightening means for urging said second male fastener towards said second female fastener, such that when said second male and female fasteners are tightened said sheath is impinged between an exterior of said insert and an interior of said second male fastener.
An EMI transfer fitting comprising:
- a first coupler for connection to a first piece of conduit, said first coupler having a distal end engaging with said first piece of conduit and a proximal end opposite said distal end;
- and,
- a second coupler attached to said proximal end, said second coupler having an attachment means for connecting to a flexible conduit for carrying a sheathed cable therein, said second coupler further having a male fastener, a hollow insert for passing said cable therethrough and passing said sheath thereover, and a female fastener, said male fastener and said female fastener having a cooperating tightening means for urging said male fastener towards said female fastener, such that when said male and female fasteners are tightened said sheath is impinged between an exterior of said insert and an interior of said male fastener.
