Abstract
Abstract A terminal for establishing electrical contact with the conductive shield of a cable having an aluminized Mylar® layer surrounded by an outer braid and then a layer of insulation forming a jacket. A ferrule is inserted between the outer braid and the Mylar® and is locked in place by an insulator displacement device which penetrates the insulation jacket to establish electrical contact with the shield.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
In an electrical connector surrounded by a metallic shroud into which an insulated cable having a flexible conductive shield beneath an outer layer of insulation enters through an opening in such shroud for termination on said connector, a terminal for establishing an electrical connection between the shield and the shroud comprising a ferrule positioned on said cable beneath and supporting a portion of said flexible conductive shield, and a "U"-shaped insulation penetrating device penetrating the outer layer of insulation and capturing said ferrule and said shield and establishing contact with the flexible conductive shield with an inward compressive force while presenting an outwardly projecting portion, said opening in said shroud defining a spaced recess into which the outwardly projecting portion of the insulating penetrating device fits and makes contact with the shroud.
Claim 2
Dependent Claim
132 words
In an electrical connector surrounded by a metallic shroud into which an insulated cable having a flexible conductive shield beneath an outer layer of insulation enters through an opening in such shroud for termination on said connector, a terminal for establishing an electrical connection between the shield and the shroud comprising a ferrule positioned on said cable beneath and supporting a portion of said flexible conductive shield, and a "U"-shaped insulation penetrating device penetrating the outer layer of insulation and capturing said ferrule and said shield and establishing contact with the flexible conductive shield with an inward compressive force while presenting an outwardly projecting portion, said opening in said shroud defining a spaced recess into which the outwardly projecting portion of the insulating penetrating device fits and makes contact with the shroud.
Claim 3
Dependent Claim
23 words
The terminal as defined in claim 1, said ferrule being longitudinally split at one location and supporting the shield with an outward force.
Claim 4
Dependent Claim
28 words
The terminal as defined in claims 1 or 2, said ferrule having an outwardly projecting collar spaced from the outwardly projecting portion of the "U"-shaped insulation penetration device.
Claim 5
Dependent Claim
26 words
The terminal as defined in claim 1 said ferrule having a diameter "d" slightly larger than the diameter "D" of the exposed end of the cable.
Claim 6
Dependent Claim
87 words
In an insulated cable having a flexible conductive shield beneath an outer layer of insulation, a terminal for establishing an electrical connection with the shield, said electrical connection comprising: a ferrule positioned on said cable beneath said conductive shield, said ferrule supporting a portion of said shield; and a "U"-shaped insulation penetration device having an opening sized to capture said ferrule and said shield and contact said shield with an inward compressive force, said "U"-shaped device having a portion projecting outwardly from said outer layer of insulation.
Claim 7
Dependent Claim
87 words
In an insulated cable having a flexible conductive shield beneath an outer layer of insulation, a terminal for establishing an electrical connection with the shield, said electrical connection comprising: a ferrule positioned on said cable beneath said conductive shield, said ferrule supporting a portion of said shield; and a "U"-shaped insulation penetration device having an opening sized to capture said ferrule and said shield and contact said shield with an inward compressive force, said "U"-shaped device having a portion projecting outwardly from said outer layer of insulation.
Claim 8
Dependent Claim
23 words
The terminal as defined in claim 5 said ferrule being longitudinally split at one location and supporting the shield with an outward force.
Claim 9
Dependent Claim
40 words
The terminal as defined in claims 5 or 6, said ferrule having an outwardly projecting collar at one end and the diameter "d" of the ferrule is slightly larger than the diameter "D" of the exposed end of the cable.
