Definitions
- This invention relates to a metal to plastic interconnection 5 device. More particularly, the invention relates to a device for interconnecting plastic and metal parts to restrain both axial and circumferential movement of the parts.
- the present invention involves an insert molding or post mold press fit of a metal sleeve to the inner diameter of a plastic molded part which is then press fitted to another part.
- the plastic molded part with the insert is then press fitted to a rigid metal housing.
- FIG. 1 is a perspective view of the interconnection of this
- FIG. 2 is a longitudinal, sectional view, illustrating the structure and association of the sleeve within plastic and metal parts.
- FIG. 3 is a cross-sectional view taken along line 3-3.
- FIG. 4 is an elevational view of another embodiment of the invention in which a base member is plastic and a metal sleeve is fitted onto the outside of the base member.
- FIG. 5 is a top view of the embodiment shown in FIG. 4. DETAILED DESCRIPTION OF THE INVENTION
- rigid base member 12 has an annular opening 10 which extends into base member 12 for receiving plastic body member 14.
- Plastic body member 14 is cylindrical in shape and is adapted to receive sleeve member 16. The interfitting parts are dimensioned to be press fitted together. With sleeve member 16 in place, plastic body member is press fitted into base member 12 to form an interconnection.
- sleeve member 16 is positioned over the outer circular surface of plastic base member 22 and cylindrical plastic or metallic member 24 is press fitted into the base member.
- Member may be hollow or solid.
- plastic parts can be made economically by molding processes. These parts are less expensive and lighter in weight than parts which are machined or molded from metal.
- thermoplastic parts is particularly desirable from a recycling standpoint.
- Preferred plastic materials which can be recycled include thermoplastic polyesters such as those disclosed in U.S. Patent 4,352,904. Such materials may contain fillers or reinforcing agents such as glass fibers. Other materials having similar properties such as modified epoxies, polyurethanes, various polyhydrocarbons, acrylics, polyvinyl chloride, polyamides, polyacetals and acrylonitrile may be used.
- the metal parts for the interconnection may be steel, aluminum, brass or various well known alloys.
- Typical applications for the interconnection of this invention include engine block and transmission case core plugs, steering wheel gear plugs and numerous other applications where one part is press fitted on the inside or outside of another part.
- end cap dust covers for an automotive streering rack were fabricated from a reinforced polyester compositon, Rynite ® 545 sold by E. I. du Pont de Nemours & Co. The dust covers were assembled to form an interconnection as shown in FIGS. 1-3.
- Base member 12 was cast aluminum and metal sleeve 16 was made from mild steel. Pull tests were conducted over a three day period under the environmental conditions shown in the following table:
