Versions are essentially only of the elastic preload depends with which their parts lie against each other. This one see the rubber-elastic ones that come into question for such plugs Materials diminished over time, is the serviceability the plug is limited in time.

The invention is based on the object of creating a plug with a multi-part, rubber-elastic housing whose tightness and strength is largely independent of the elastic pretension with which the parts "lie against one another" where the lower part of the cross-sectioned connector, which carries the steek pins, the protective contacts and a strain relief device, is coupled to a rubber-elastic upper part through a detachable connector extending parallel to the connector. The compression of the ropes is therefore produced independently of the flexibility of the material used for this material. This is de for ^one permanence "plug is essential because the guamielastißche material is not subject to permanent strain, di * Experience shows that quickly leads to an impairment of the elastic properties · The lower part of the connector may be made of starrea, supporting the KimtafctaltteX and the strain relief Fur stable · Since suitable materials are usually impact-sensitive, it is advisable to provide such ropes at least partially with a rubber-elastic covering. The rigid core can then optionally be limited to a bridge holding the contact pins at the required spacing and preferably supporting the strain relief device. But it is also possible

Lower part seated peg is connected. The protective contact bracket is preferably firmly embedded in the lower part. This can be done in a simple manner in that it is attached directly to the bridge that keeps the contact pins at the required distance. The peg of the protective contact bracket carrying the strain relief device can be used to hold the bracket securely in a 4-piece compression or Prltzfora in which the bridge is encased in a 1% elastic material.

Finally, the cable entry grommet also had protruding annular ribs in the area of its cable ducts, which lay lidded against the cable and which are therefore suitable for compensating for wide diameters. Furthermore, "the cable duct of the insertion sleeve could be provided with one or more bead-like constrictions" which are elastically widened when the cable is inserted, for which purpose known tools can be used if necessary; In order to ensure sufficient deformability, it was recommended to make the cable entry nozzles relatively thin-walled in the area of the constrictions · This has a further beneficial effect, especially when the constriction points are in the area of the attachment of the cable entry grommet, and then the entry grommet can see here “to absorb part of the operational bending deformation, so that the stresses on the cable are kept low.
