Clamping cable for connector units and cable connector unit comprising such a clamping element
A clamping element ( 10 ), which can be radially compressed at least in part, and engages around and clamps a cable (K) of a cable connector unit once the threaded connection of clamping sleeve ( 3 ) and housing ( 1 ) is tightened. A cable connector unit using such a clamping element ( 10 ) is also provided.
1 . A clamping part for clamping a cable in a cable connector assembly, the clamping part comprising:
at least one radially compressible section that encloses the cable and clamps the cable in the compressed state;
a front edge region for resting against at least one of a housing of the cable connector assembly or a connector extension inserted therein;
a rear section formed by a number of clamping tongues distributed around a circumference of the clamping part, and the clamping tongues include at least two different kinds of the clamping tongues;
wherein each of the clamping tongues of a first group of the clamping tongues is wider, at least at an end facing away from the clamping part, than the clamping tongues of a second group of the clamping tongues; and
wherein the clamping tongues of the first group widen continuously as a distance from the front edge region of the clamping part increases.
2 . The clamping part as claimed in claim 1 , wherein the clamping tongues in a first group of the clamping tongues are beveled on side edges thereof, and a width increases as a distance from a central axis of the clamping part becomes radially greater.
3 . The clamping part as claimed in claim 1 , wherein the clamping tongues of the first group have a section at ends thereof which is adapted to exert a clamping action on a cable for form-fitting penetration of a jacket of the cable.
4 . The clamping part as claimed in claim 1 , wherein each of the clamping tongues of the second group of the clamping tongues is narrower than the clamping tongues of the first group.
5 . The clamping part as claimed in claim 1 , wherein side edges of the clamping tongues of the second group extend parallel to one another.
6 . The clamping part as claimed in claim 1 , wherein a region that is adapted to increase a holding effect on the cable extends from an outer end of the clamping tongues in the second group of the clamping tongues toward an inner end thereof.
7 . The clamping part as claimed in claim 1 , wherein the clamping tongues are elastically compressible in a radial direction.
