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.
