Abstract
The invention relates to a connector for a cable for underground mining, comprising a socket part 1 and a plug part axially insertable into the socket part and having a hole in the back for inserting a cable, the plug part being secured to the socket part 1 by a screw cap 20 mounted for rotation on the plug part 10 and screwable on to an external thread 6 on the socket part 1 and being sealed against penetration of moisture and/or dirt by at least one sealing element. In order to obtain standard parts for a family of plugs by a simple assembly process and with maximum sealing-tightness against moisture and dirt and at low production costs, the plugs being suitable for inserting the cable either coaxially or radially, the external thread 6 on the socket part 1 and the associated internal thread 21 on the screw cap 20 are triple threads and/or a crown part 40 with at least one radial recess 41 for receiving the cable 30 is provided on the cable entry hole 18 on the back of the plug part.
