Connection assembly for connecting metallic and plastic components and method of connecting plastic and metallic components

摘要

A connection assembly for attaching metallic and plastic components by a heat staking operation includes a first component, a second component, a compressible protrusion, an annular collar, and a deformable stud. The first component is formed of a metallic material and includes an inner surface. The second component includes an interior surface facing the inner surface of the first component and an opposite exterior surface. The second component includes a plurality of apertures which extend between the interior surface and the exterior surface. During the heat staking operation the deformable stud is deformed so as to restrain relative movement between the first and second components. The compressible protrusion plastically deforms to absorb pressure to prevent cracking of the second component and the annular collar absorbs heat to prevent the second component adjacent the aperture from melting.

主权项

1. A connection assembly for attaching two components by heat staking a deformable stud, said assembly comprising:
a first component formed of a metallic material, said first component having an inner surface; a second component formed of a plastic material, said second component having an interior surface and an opposite exterior surface, said interior surface facing said inner surface of said first component, said second component having an aperture extending between said interior surface and said exterior surface, the second component having a compressible protrusion extending outwardly from said exterior surface adjacent said aperture; and a hollow annular collar having a radially extending flange at a first end, said annular collar positioned within said aperture such that a bottom surface of said flange covers said compressible protrusion.
