Abstract: An inner conductor contact for connecting one end of a braided inner conductor of a coaxial cable with one end of an inner conductor of a coaxial plug, with the inner cable conductor enclosing a core which is retracted relative to the end of the inner cable conductor, includes a support element insertable in the inner cable conductor and having the same diameter as the core. The support element is adapted for connection with the core at the core-near side thereof via a bolt and with the inner plug conductor at the core-distant side thereof by means of a prolongation which is connected to the support element via a conical shoulder and thus is of smaller diameter than the support element. The part of the inner cable conductor extending along the shoulder and prolongation is surrounded by a metal bushing which receives the respective end of the inner plug conductor to provide the electric connection between the inner cable conductor and the inner plug conductor.

The plastic ring is sandwiched between the metal casing and a fastener such as a coupling ring or hollow screw, after threadably engaging the latter to the metal casing and thus becomes axially compressed and widens radially to create a form closure with the conductor.

Abstract: A sealed cable connector includes a plug or coupler with a sleeve extending over the cable end and surrounding a strain relief ring, contoured annular seal and a thrust collar. The seal includes an outer ring and an inner ring which are connected with each other by a radial bridge. During assembly, the thrust collar and the strain relief ring cooperate with each other in such a manner that upon axial displacement of the thrust collar toward the strain relief ring by means of a screw plug turned into the sleeve, the bridge becomes sheared off thereby compressing the inner and outer rings within the respective inner and outer spaces between the thrust collar and the strain relief ring while at the same time the thrust collar presses the outer cable conductor against a contacting face of the sleeve.
