Electrical connector apparatus and method
First Claim
1. An electrical interconnect apparatus for forming an electrical connection between spaced apart first and second electrical contact points of a pair of adjacent electrical components, the apparatus comprising:
- a compressible substrate having at least one hole formed therethrough;
a flexible electrical circuit having at least one circuit trace electrically coupling spaced apart first and second electrical contact portions, said flexible electrical circuit having at least one hole and being laid over at least a portion of said compressible substrate; and
a holder structure securable to one of the pair of adjacent electrical components for securing said compressible substrate in a compressed state against each of said pair of electrical components such that said first and second electrical contact portions are compressed into contact with said first and second electrical contact points;
said holder structure including an alignment member extending from said holder structure, through said holes in said compressible substrate and said flexible electrical circuit, and engageable with a surface portion of said one electrical component, to thus key said flexible electrical circuit in a position relative to said one electrical component.

Abstract
An electrical connector apparatus and method for connecting circuit traces on two or more independent circuit board assemblies. A compressible elastomeric member is wrapped with a flexible circuit assembly having a plurality of independent circuit traces, with each circuit trace including a pair of raised electrical contacts. The compressible member with the electrical circuit wrapped over it is supported by a holder assembly. The holder assembly is secured to one of a pair of adjacently positioned independent printed circuit assemblies. The compressible member is held by the holder assembly so that it is compressed against both of the printed circuit board assemblies. The raised electrical contacts electrically contact traces on each of the printed circuit assemblies to complete the electrical connections between the circuit assemblies. The apparatus is especially useful in applications where a large plurality of electrical connections need to be made between independent circuit board assemblies in a very limited space.
