Abstract
Abstract A method of forming an end suitable for electric coupling, on a coaxial cable having a flexible metal shield and a synthetic outer sheath. The outer sheath is cut circumferentially at a distance from the cable end, the end portion of the outer sheath is moved in the direction of the cable end so that the moved portion projects partly beyond the cable end, the end portion of the outer sheath is shortened, and then moved back while clamping against the metal shield, so that the metal shield is upset in the form of an umbrella and the insulated conductor is exposed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A method of forming an end connection arrangement on a coaxial cable having a central conductor, a layer of insulation surrounding the conductor, a flexible metal shield around the insulation layer, and a synthetic material outer sheath, comprising cutting circumferentially through the outer sheath at a location spaced a first distance from the cable end, thereby defining an end portion of said sheath, moving said end portion of the sheath in a first direction toward said cable end a distance less than said first distance, whereby said end portion projects partly beyond the cable end, removing a distal end part of said end portion so as to shorten said end portion, and moving the shortened end portion in the direction opposite said first direction while clamping the end portion against the metal shield, so as to upset the shield and expose the insulated central conductor.
Claim 2
Independent Claim
145 words
A method of forming an end connection arrangement on a coaxial cable having a central conductor, a layer of insulation surrounding the conductor, a flexible metal shield around the insulation layer, and a synthetic material outer sheath, comprising cutting circumferentially through the outer sheath at a location spaced a first distance from the cable end, thereby defining an end portion of said sheath, moving said end portion of the sheath in a first direction toward said cable end a distance less than said first distance, whereby said end portion projects partly beyond the cable end, removing a distal end part of said end portion so as to shorten said end portion, and moving the shortened end portion in the direction opposite said first direction while clamping the end portion against the metal shield, so as to upset the shield and expose the insulated central conductor.
Claim 3
Dependent Claim
30 words
A method as claimed in claim 1, characterized in that said moving step moves the shortened end portion substantially back to its original position with respect to the central conductor.
Claim 4
Dependent Claim
51 words
A method as claimed in claim 2, characterized in that said removing step removes less than the entire projecting portion of said end portion, whereby upon completion of said moving step the sheath end portion extends beyond the end of the shield which is between the sheath and the insulation layer.
Claim 5
Dependent Claim
45 words
A method as claimed in claim 2, characterized in that moving the shortened end portion in said opposite direction upsets the flexible shield into an umbrella shape, and in that there is a following step of pressing the upset shield axially over the outer sheath.
Claim 6
Dependent Claim
23 words
A method as claimed in claim 4, wherein said shield is pressed axially in a direction away from the end of the cable.
