Abstract
An internal shield ground adapter uses spring contacts inside the kickpipe/stuffing tube to make a wideband, low impedance 360 degree contact between the shield of a cable passing through the kickpipe/stuffing tube and the kickpipe/stuffing tube itself. An environmental seal compresses the spring contacts against both the cable shield and kickpipe/stuffing tube while preventing degradation of the system by environmentally sealing the area between the cable and kickpipe/stuffing tube.
Claims8
An internal shield ground adapter system comprising:
- a plate having an aperture;
- a metallic tube of predetermined length having the opening at a first end of said predetermined length tapering to a smaller opening along a length segment of said tube, said tube extending through said plate with a portion of the outer surface of said tube affixed to the plate in the area surrounding said plate aperture, the second end of said tube extending beyond said plate;
- a shielded cable having a portion of its shield exposed, said shielded cable extending through said tube and said plate aperture;
- a metallic spring system contacting said exposed shield and the inner surface of said length segment of said tube that tapers to said smaller opening;
- compression and sealing means extending through said first end of said tube to compress said metallic spring system against both said shield and said inner surface of said tube in said length segment of said tube that tapers toward the smaller opening, and to environmentally seal the area between said first end of said tube and said shielding cable;
- and
- electromagnetic sealing means, comprising an electromagnetic interference seal affixed to the second end of said tube, and said electromagnetic interference seal together with said cable enclosing the second end of said tube, for preventing electromagnetic energy from exiting through the second end of said tube.
