Abstract
What is proposed is an apparatus for a shielded terminal connector that eliminates EMI leakage from coaxial cables in which a resilient bushing of a conductive material is inserted between exposed shield portions of the coaxial cable and the interior surface of a backshell housing, the latter being compressed onto a connector housing for the cable and the resilient bushing itself so that the bushing is gripped tightly by the backshell housing and thus completely fills the space between the exposed shield portions of the cable and the surrounding interior surface of the backshell housing.
Claims7
A non-threadable shield terminal connector apparatus for eliminating EMI leakage comprising,
- at least one coaxial cable having an exposed shield portion,
- a generally tubular backshell housing having generally smooth exterior and interior surfaces for containing said shield portion,
- a resilient bushing of conductive material contiguously surrounding said shield portion and radially extending to the interior surface of said backshell housing, whereby the space between the shield portion of said cable and the adjacent interior surface of said backshell housing is completely filled by said resilient bushing, and
- said backshell housing having a rim surrounding said resilient bushing and said coaxial cable, at least a portion of said rim being plastically deformed toward said coaxial cable for retention of said resilient bushing.
A shield terminal connector apparatus for eliminating EMI leakage comprising,
- at least one coaxial cable having an exposed shield portion,
- a generally tubular backshell housing for containing said shield portion,
- a resilient bushing of conductive material contiguously surrounding said shield portion and radially extending to the interior surface of said backshell housing, whereby the space between the shield portion of said cable and the adjacent interior surface of said backshell housing is completely filled by said resilient bushing,
- wherein said backshell housing terminates onto a connector housing on one side of said resilient bushing and as a rim portion surrounding said coaxial cable on the other side of said resilient bushing, and
- wherein said coaxial cable comprises an outer sheath convering turned back on itself within said rim portion of said backshell housing, and a support ring member contained by said back-turned portion of said cable.
