초록 ▼

Various cable entry port assemblies are disclosed. One embodiment includes a single boot assembly for supporting one power cable. Another embodiment includes two or more boot assemblies supported along a horizontal axis. Other embodiments include at least two boot assemblies supported along a vertically extending axis to form a column of boot assemblies. Another embodiment includes at least one column of boot assemblies and at least one row of boot assemblies. Methods for reducing an amount of interference traveling on a cable from one component located outside of a structure to another component located within the structure are also disclosed.

What is claimed is: 1. An entry port for a supporting a cable having an outer shield conductor covered by a sheath, comprising: an attachment flange; an electrically conductive boot assembly coupled to said attachment flange; a first electrically conductive retainer shield supported within said boot assembly to contact an exposed portion of the outer shield conductor of the cable; and a second electrically conductive retainer shield supported within said boot assembly, said second retainer shield establishing a seal with a portion of the cable sheath. 2. The entry port of claim 1 wherein said electrically conductive boot assembly is fabricated from an electrically conductive material and wherein said first electrically conductive retainer shield is fabricated from said electrically conductive material. 3. The entry port of claim 2 wherein said attachment flange is fabricated from a metal and wherein said electrically conductive material is fabricated from non-metal material having filings of said metal embedded therein. 4. The entry port of claim 3 wherein said metal comprises aluminum. 5. The entry port of claim 1 wherein said boot assembly is removably coupled to said attachment flange. 6. The entry port of claim 5 wherein the boot assembly is removably clamped to said attachment flange. 7. The entry port of claim 1 wherein said second retainer shield is fabricated from a second material that differs from a first material from which said first retainer shield is fabricated from. 8. The entry port of claim 1 wherein said first and second retainer shields are removably retained within said boot assembly. 9. The entry port of claim 8 wherein said first and second retainer shields are retained within said boot assembly by at least one clamp. 10. The entry port of claim 1 further comprising an auxiliary shield member attached to said attachment flange and a portion of the outer shield conductor of the cable external to said boot assembly. 11. The entry port of claim 10 wherein said auxiliary shield member is flexible and extends around a perimeter of said attachment flange and a perimeter of the outer shield conductor of the cable external to said boot assembly. 12. The entry port of claim 1 wherein said attachment flange protrudes from an entry plate and wherein said entry port further comprises at least one shield strap attached to another exposed portion of the outer shield conductor of the cable and said entry plate. 13. The entry port of claim 1 wherein said attachment flange is fabricated from a material that comprises a wall to which said attachment flange is to be attached. 14. The entry port of claim 13 further comprising: a first annular compatibility area between said attachment flange and said wall to which said attachment flange is to be attached; a second annular compatibility area between said attachment flange and said boot assembly; and a third annular compatibility area between said first retainer shield and said boot assembly. 15. The entry port of claim 14 further comprising a fourth annular area of compatibility between said first retainer shield and a portion of said cable. 16. An entry port for a supporting a cable through a wall, the cable having an outer shield conductor fabricated from a core material and being covered by a sheath, the entry port comprising: an attachment flange for attachment to the wall and being fabricated from a first material that comprises the wall; an electrically conductive boot assembly fabricated from a second non-metal material having portions of said first material embedded therein and removably affixed to said attachment flange; a first annular retainer shield fabricated from said second material having portions of the core material therein and being retained within said boot assembly to contact an exposed portion of the outer shield conductor of the cable; and a second annular retainer shield fabricated from said second material and being supported within said boot assembly to sealingly contact a portion of the sheath of the cable; and at least one clamp member extending around the perimeter of said boot assembly for clampingly retaining said first and second retainer shields within said boot assembly. 17. A method for reducing an amount of interference traveling on a cable from one component located outside of a structure to another component located within the structure, wherein the cable has an outer shield conductor covered by a sheath, said method comprising: forming a cable-receiving opening in an exterior wall of the structure; affixing an attachment flange to the exterior wall portion in registration with the cable-receiving opening therein; affixing a conductive boot assembly to the attachment flange, the conductive boot assembly containing an electrically conductive first retainer shield therein; removing a portion of the cable sheath to expose a portion of the outer shield conductor of the cable; passing the cable through the conductive boot assembly, attachment flange and cable receiving opening, such that the first retainer shield contacts exposed portion of the outer shield conductor of the cable; and grounding the attachment flange.
