The invention relates to a plug-in cable connector 3 for electrical cable or plug connections 10. The cable connector 3, which forms the termination of the cable 1, has a hollow connector shell 4 of brass, whose boring forms a cable entry opening on its cable side section and an abutment collar 5 on which a plug connector 6 with a collar 6′ is supported axially in one direction. The cable entry opening is provided with an internal thread 22, in which a four cornered part 30 of metal, having a through boring 35 for the cable, is screwed in. The screening or armouring of the cable 1 can be accepted between the through boring 25 and the cable covering 1′, so that a good earthing of the cable 1 and the cable connector 3 can be achieved. The interior space of the connector shell 4 is sealed by means of a formed part 27, which is formed onto the cable covering 1′, the connector shell 4 and the multi-cornered part 30. The cable 1 is also retained axially on the connector shell 4 by the formed part 27.
A cable plug connector for electrical cable connections, especially for plug-in couplings of electrical cable connections in underground mining, with a connector shell of metal, which has a cable entry end and a cable entry opening therein, said opening provided with an internal thread and an abutment collar or engaging portion for a plug connector of plastics material, which is equipped with plug pins and/or sockets, which are joined to the cable conductors of a single or multi-connector cable, which is provided with screening or armouring, a multiple cornered part of metal being provided with threaded sections on its corner edges and also provided with a through boring for the cable, wherein the multiple cornered part is screwed into the cable entry opening of the connector shell such that the threaded sections of the corner edges engage the internal thread of the connector shell and the cable is fastened in a sealed manner, by means of a formed part formed on the cable covering, to the multiple cornered part and to the connector shell.
