Abstract

An interconnector device for electrical conductors and compression assemblies therefor has a plurality of rigid electrically conductive rods, each rod being imbedded in a fixed cross-sectional plane of a dielectric, compressible core and projecting therefrom, whereupon application of an orthogonal compressive force will cause the rods to rotate relative to the core thereby causing the ends of the rods to move along two non-coincident lines of action to establish wiping electrical connection with the conductors.

Claims

1. An electrical connector for electrically connecting first and second circuit members, each member having a surface including conductive means, comprising:

a dielectric member of compressible elastomeric material;

substantially rigid electrically-conductive linear rod members secured at spaced intervals in said dielectric member and extending through said dielectric member substantially normal to a longitudinal axis of said dielectric member;

said rod members extending at an acute angle with respect to the surfaces of the circuit members when in electrical engagement therewith; and

ends of said rod members extending outwardly from different surfaces of said dielectric member and electrically engageable with respective conductive means of the first and second circuit members upon said dielectric member being pressed against the surfaces of the circuit members in a direction to bring the ends of the rod members into electrical engagement with respective conductive means.

2. An electrical connector as claimed in claim 1, wherein said dielectric member has a rectangular configuration.

3. An electrical connector as claimed in claim 2, wherein the surfaces of said dielectric member from which the ends of said rod members extend are opposing surfaces.

4. An electrical connector as claimed in claim 2, wherein the surfaces of said dielectric member from which the ends of said rod members extend are adjacent surfaces.

5. An electrical connector as claimed in claim 2, wherein said dielectric member has recesses in the surfaces of said dielectric member in which the ends of said rod members are disposed.

6. An electrical connector as claimed in claim 5, wherein the outer surfaces of the ends of said rod members are coextensive with outer surfaces forming the recesses.

7. An electrical connector as claimed in claim 1, wherein said ends have a convex configuration.

8. An electrical connector as claimed in claim 1, wherein said rod members are disposed in said dielectric member in a plane extending along the length of said dielectric member.

9. An electrical connector assembly for electrically connecting first and second circuit members, each member having a surface including conductive means, comprising:

housing means having an opening therein;

a dielectric member of compressible elastomeric material disposed in said opening;

substantially rigid electrically-conductive rod members secured at spaced intervals in said dielectric member and extending through said dielectric member substantially normal to a longitudinal axis of said dielectric member, said rod members extending at an acute angle with respect to the surfaces of the circuit members when in electrical engagement therewith;

ends of said rod members extending outwardly form different surfaces of said dielectric member and electrically engageable with respective conductive means of the first and second members upon said dielectric member being pressed against the surfaces of the circuit members in a direction to bring the ends of the rod members into electrical engagement with the conductive means; and

means provided by said housing means for accommodating part of said compressible dielectric member when the compressive force causes said dielectric member to be distorted from its original configuration.

10. An electrical connector as claimed in claim 9, wherein said accommodating means comprises at least one beveled surface along an inside surface of said housing means.

11. An electrical connector assembly as claimed in claim 9, wherein said accommodating means comprises beveled surfaces along opposing inside surfaces of said housing means.
