Abstract

The utility model discloses a cable coupling assembly which comprises a tapered bolt with a head part being connected with a track circuit cable. The rod-like body of the tapered bolt comprises a tapered part tapering in the direction from the head part to the rod-like body. The cable coupling assembly further comprises an elastic casing which is inserted on a steel rail web. A tapered hole accommodating the tapered part is opened on the inner wall of the elastic casing. One end of the rod-like body of the tapered bolt being far away from the head part passes through the inner hole of the elastic casing. The outer wall of the tapered part is tightly propped against the inner wall of the tapered hole. A screw is also arranged at one end of the rod-like body far away from the head part. The tapered screw can be tightly locked by the screw on the steel rail web. The utility model realizes the close connection between the tapered screw or the elastic casing and the end surface of the steel rail web without any clearance, ensures stability in metal property of the cable coupling assembly after long-term use, and prevents rusting.
