Embedding metal components in plastic, especially when forming high voltage cable terminations and joints is facilitated by axially-symmetrical undercut recess in metal, filled by casting resin

摘要

The metal component (1) includes undercut (3a, 3c) recess(es). These are filled by material of, and continuous with, the plastic component (2). Preferred features: The metal component is rotationally-symmetrical with respect to an axis of symmetry (A). It forms part of an electrical cable termination. The plastic is a duroplastic, elastomer or thermoplastic. It is a duroplastic casting resin. The shape of the recess(es) is mushroom, rectangular, dovetail, spherical, rivet-like, bollard-shaped or triangular.
