Mechanical and electrical connection between an extruded metal profile and a cast metal member
First Claim
1. A mechanical and electrical connection between an extruded metal profile and a cast metal member, with the cast member being provided with a peg-like projection adapted to the interior configuration of the extruded profile and insertable into the extruded profile, comprising at least one spring having a greater hardness than the extruded profile said cast member being disposed between mutually facing faces of the extruded profile and the projection, said spring including shaped-on barbs which claw into the extruded profile and the projection.

Abstract
The present invention relates to a mechanical and electrical connection between an extruded metal profile and a cast metal member. The cast member is provided with a peglike projection which is adapted to the interior configuration of the extruded profile and is insertable into the extruded profile. In order to realize a connection which is reliable even under mechanical stresses, which does not interfere with the subsequent lacquering and burn-in processes and which, moreover, is invisible, the invention provides that a spring of a hardness greater than both the extruded profile and the cast member is disposed between mutually facing faces of the extruded profile and the cast member. Barbs are shaped onto the cast member so as to engage in both components.
