Abstract
Abstract An RF-shielded coupling part of a cable having a shielding sheath within jacket is provided, which can be firmly mounted to the cable in a simple and RF-tight way by using simple parts. For this purpose, a metallic stopper is firmly pushed onto the jacket, which surrounds the circumference of the jacket. The contact area of the shielding sheath is solderlessly clamped in between the stopper and a slotless shield. The shield is in a close relationship to the stopper at its entire circumference and is held to the stopper in a form-fit connection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
An RF-shielded coupling part for a multiwire cable having a shielding sheath within its jacket, in which the shielding sheath, in a contact area stripped of the jacket, is in an electrically conductive connection to a metallic shield, further comprising: a metallic stopper pushed onto the jacket surrounding the circumference of the jacket and secured in position in a direction longitudinal to the cable; wherein the contact area of the shielding sheath is solderlessly clamped in between the stopper and the shield; and wherein the stopper sits in a close relationship to the shield about its entire circumference and the shield is held in a force-fit around the stopper in the longitudinal direction of the cable; wherein the stopper comprises a conical circumferential surface onto which the shield is slipped to form a tight fit; wherein the stopper comprises a web as a stop for an edge of the shield; and wherein the web is interrupted by recesses, through which lugs on the shield project, which lugs are bent and reach behind the stopper.
Claim 2
Dependent Claim
174 words
An RF-shielded coupling part for a multiwire cable having a shielding sheath within its jacket, in which the shielding sheath, in a contact area stripped of the jacket, is in an electrically conductive connection to a metallic shield, further comprising: a metallic stopper pushed onto the jacket surrounding the circumference of the jacket and secured in position in a direction longitudinal to the cable; wherein the contact area of the shielding sheath is solderlessly clamped in between the stopper and the shield; and wherein the stopper sits in a close relationship to the shield about its entire circumference and the shield is held in a force-fit around the stopper in the longitudinal direction of the cable; wherein the stopper comprises a conical circumferential surface onto which the shield is slipped to form a tight fit; wherein the stopper comprises a web as a stop for an edge of the shield; and wherein the web is interrupted by recesses, through which lugs on the shield project, which lugs are bent and reach behind the stopper.
Claim 3
Dependent Claim
19 words
A coupling part according to claim 1, wherein the contact area is turned back onto the conical circumferential surface.
Claim 4
Dependent Claim
40 words
A coupling part according to claim 1, wherein the stopper comprises a collar which meets an end of the jacket in the longitudinal direction of the cable and around which the shielding sheath is led and pressed toward the cable.
Claim 5
Dependent Claim
20 words
A coupling part according to claim 1, wherein the stopper is firmly secured to the jacket by means of indentations.
Claim 6
Dependent Claim
63 words
A coupling part according to claim 1, wherein the stopper comprises a head portion and a neck portion which, relative to the head portion, has a thinner wall, wherein the shield is disposed at the head portion and wherein the neck portion projects beyond the shield in the longitudinal direction of the cable and is secured to the jacket by means of indentations.
