Abstract
Abstract A shielded backshell system (24,26,28,30) provides strain relief to a cable (52) and assures electrical continuity between the cable shield (182) and a shielded backshell member (24 or 26). The shielded backshell assembly (24, 26) includes shielding means (24 or 26) having a cable passage (86) for receiving the shielded cable (52). The shielding means (24 or 26) has an extension (88) extending proximate the cable exit (86). Insert means (32,34) are received in the shielded backshell system proximate the cable exit (86) to engage and compress the cable (52) while simultaneously pressing the shielding member extension (88) into engagement with the shield (182) on the cable (52) to provide electrical continuity therewith.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
160 words
A shielding assembly for providing strain relief and electrical continuity to a shielded cable received therein, the shielded cable having a portion of the shield exposed, said shielding assembly comprising: shield means defining a cavity for receiving a portion of the shielded cable, said shield means having a cable exit and an extension proximate the cable exit; insert means having first and second surfaces, said insert means adapted to be received in the shielding assembly, the first surface adapted to slide along a ramped surface of the shielding assembly, the second surface adapted to engage the cable and extension as the insert means is slid along the ramped surface, thus compressing the cable and pressing the extension into engagement with the cable shield, whereby strain relief for the cable and electrical continuity between the cable shield and the shield means are simultaneously achieved as the second surface of the insert means presses the cable and extension in the same direction.
Claim 2
Dependent Claim
160 words
A shielding assembly for providing strain relief and electrical continuity to a shielded cable received therein, the shielded cable having a portion of the shield exposed, said shielding assembly comprising: shield means defining a cavity for receiving a portion of the shielded cable, said shield means having a cable exit and an extension proximate the cable exit; insert means having first and second surfaces, said insert means adapted to be received in the shielding assembly, the first surface adapted to slide along a ramped surface of the shielding assembly, the second surface adapted to engage the cable and extension as the insert means is slid along the ramped surface, thus compressing the cable and pressing the extension into engagement with the cable shield, whereby strain relief for the cable and electrical continuity between the cable shield and the shield means are simultaneously achieved as the second surface of the insert means presses the cable and extension in the same direction.

Claim 7
Dependent Claim
20 words
A shielding assembly as recited in claim 1, further comprising cover means defining a cavity for receiving the shielding means.
Claim 8
Dependent Claim
18 words
A shielding assembly as recited in claim 6, wherein the cover means comprises a pair of hermaphroditic covers.
Claim 9
Dependent Claim
58 words
A shielding assembly as recited in claim 6, wherein the shielding means further comprises a groove, the cover means further comprising a complementary rib adapted to be received in the groove, whereby when the cover means is disposed about the shielding means, the rib is received in the groove to position the cover means on the shielding means.
Claim 10
Dependent Claim
193 words
A shielding assembly for providing strain relief and electrical continuity to a shielded cable received therein, the shielded cable having a portion of the shield exposed, said shielding assembly comprising: shield means defining a cavity for receiving a portion of the shielded cable, said shield means having a cable exit and an engagement means proximate the cable exit; cover means defining a cavity for receiving the shield means, said cover means having a cable exit, said cover means having a ramped surface proximate said cable exit; insert means having first and second surfaces, said insert means adapted to be received in the cover means, the first surface adapted to slide along the ramped surface of the cover means, the second surface adapted to engage the cable and engagement means as the insert means is slid along the ramped surface, thus compressing the cable and pressing the engagement means into engagement with the cable shield, whereby strain relief for the cable and electrical continuity between the cable shield and the shield means are simultaneously achieved as the second surface of the insert means presses the cable and the extension means in the same direction.
