Abstract

An integrally molded electrical connector 10 for interconnecting an array 60 of conductors of a first article 58 with a corresponding array 64 of conductors of a second article 62 includes a plurality of substantially rigid bifurcated tines joined by a bight section 30, each tine having arm portions 18, 24 deflectable toward each other; and compressible support means 46 extending between the arm portions 18, 24 of the tines 16; and continuous circuit means 36 defined along outer surfaces of tine arm portions 18, 24 and bight section 30. The array of tines is formed from a dielectric material. The compressible support means 46 has sufficient durometer to maintain contact normal force between the continuous circuit means 36 and the corresponding contact means of opposed first and second electrical articles 58, 62 upon the arm portions 18, 24 being compressively held between the pair of electrical articles 58, 62.

Claims

1. An electrical connector for interconnecting a pair of electrical articles said connector being integrally molded from rigid and compressible materials by a dual injection molding process, said connector comprising:

at least one bifurcated substantially rigid tine having first and second arm portions coextending from a bight section and deflectable toward each other said arm portions being curved arcuately outwardly, and adapted to have circuit means defined along outer surfaces thereof, said tine being formed from a dielectric material;

support means integrally molded between said first and second arm portions, said support means being formed from said compressible material; and

continuous circuit means defined along outer surfaces of said arm and bight portions respectively of said molded member, said circuit means including first and second contact sections on said first and second arm portions respectively adapted to engage respective corresponding contact means of said pair of articles, said compressible material having sufficient durometer to maintain contact normal force between said first and second contact sections and the corresponding contact means of opposed first and second electrical articles upon said arm portions being compressively held between said pair of electrical articles.

2. The electrical connector of claim 1 wherein said compressible support means is an elastomeric material having a durometer in the range of 35-60 Shore A.

3. An assembly comprising the electrical connector of claim 1 disposed in a housing member, said housing being adapted to receive first and second electrical articles therein, said articles being electrically connected by said continuous circuit means of said arm and bight portions.

4. An assembly comprising first and second electrical articles interconnected by the electrical connector of claim 1.

5. A multiconductor electrical connector for providing a plurality of electrical interconnections between respective conductive portions of first and second electrical articles, said connector being integrally molded from rigid and compressible materials by a dual injection molding process, said connector comprising:

an array of spaced bifurcated substantially rigid tines, each said tine having first and second arm portions coextending from a bight section and deflectable toward each other, said arm portions being curved arcuately outwardly and adapted to have circuit means defined along outer surfaces thereof, said tines being formed from a dielectric material;

support means integrally molded between said first and second arm portions, and securing said array of tines together to define an integrally molded member having precisely dimensioned and exposed outer rigid surfaces having arcuate portions, said support means being formed from said compressible material; and

continuous circuit means defined along respective outer surfaces of each of said first and second arm and bight portions respectively of said molded member, said circuit means including first and second contact sections on respective said first and second arm portion adapted to engage respective corresponding contact means of said pair of articles, said support means having sufficient durometer to maintain contact normal force between said first and second contact areas and the corresponding contact means of opposed first and second electrical articles upon said arm portions being compressively held between said pair of electrical articles, said support means thereby defining a multiconductor connector for interconnecting opposed arrays of said corresponding contact means of said first and second electrical articles.

6. The electrical connector of claim 5 wherein said arm portions of said bifurcated tines are curved arcuately outwardly.

7. The electrical connector of claim 5 wherein said compressible support means is an elastomeric material having a durometer in the range of 35-60 Shore A.

8. The electrical connector of claim 5 wherein said array of bifurcated tines are spaced along a continuous carrier strip.

9. The electrical connector of claim 5 further including means for mounting said connector between first and second electrical articles.

10. An assembly comprising the electrical connector of claim 5 disposed in a housing member, said housing being adapted to receive first and second electrical articles therein, said first and second articles including first and second arrays of contact means respectively, said first and second arrays being electrically interconnected by said continuous circuit means of said arm and bight portions.

11. An assembly comprising first and second electrical articles interconnected by the electrical connector of claim 5.

12. A method for making a multiconductor electrical connector for providing a plurality of electrical interconnections between respective conductive portions of opposed first and second electrical articles, comprising:

molding an array of spaced bifurcated substantially rigid tines, each said tine having first and second arm portions coextending from a bight section and deflectable toward each other, said array of tines being molded from a dielectric material;
