Abstract
An electrical connector assembly and method of connecting an electrical connector to a substrate are provided. The electrical connector assembly includes a substrate having first electrical circuitry formed on a surface, an elastomer, and second electrical circuitry disposed at least partially between the substrate and the elastomer. Elements of the second electrical circuitry are pressed into contact with contact pads of the first electrical circuitry. The electrical connector assembly also includes a holder securing the elastomer in a compressed state to provide a pressure contact between the circuit elements and the contact pads.
Claims20
An electrical connector assembly comprising:
- a substrate;
- first electrical circuitry formed on the substrate;
- second electrical circuitry disposed at least partially on top of and in contact with the second electrical circuitry;
- an elastomer disposed at least partially on top of the second electrical circuitry, wherein the elastomer is compressible;
- and
- an overmolding material securing the elastomer such that the elastomer is compressed to provide a pressure contact between the second electrical circuitry and the first electrical circuitry on the substrate.
An electrical connector assembly comprising:
- a substrate comprising first electrical circuitry having a plurality of contact pads;
- an elastomer comprising a plurality of extension members;
- a connector harness comprising second electrical circuitry having a plurality of flexible circuit elements, said flexible circuit elements disposed at least partially between the substrate and the plurality of extension members of the elastomer, wherein the flexible connector elements are pressed into contact with the contact pads on the substrate;
- and
- an overmolding material securing the elastomer in a compressed state to provide a pressure contact between the flexible connector elements and the contact pads, wherein the overmolding material is disposed between the elastomer and the substrate.
A method of assembly an electrical connector assembly to contact circuitry on a substrate, said method comprising the steps of:
- providing a substrate having first electrical circuitry formed on a surface;
- disposing an electrical connector assembly having second electrical circuitry such that the second electrical circuitry is aligned with the first electrical circuitry on the substrate;
- applying a compressible elastomer on the second electrical circuitry;
- compressing the elastomer to provide a pressure contact between the second electrical circuitry and the first electrical circuitry;
- applying an overmolding material to the assembly;
- and
- curing the overmolding material with the elastomer compressed to maintain the pressure contact.
