High density stacking connector
First Claim
1. An electrical connector for interconnecting printed boards which have a plurality of electrical pads each distanced from another by at least twenty-five thousandths (0.025) of an inch, which comprises:
- a base formed with a cavity;
a plurality of electrically conductive contacts, each having a spring-like body portion interconnecting a respective first end point and a respective second end point, said body portion having two cantilevers joined by a bent support portion, said end points being respectively formed on said cantilevers to enable said end points to move relative to each other, each of said body portions establishing a single path for electrical conductivity between respective said end points, said contacts positionable in said cavity with said first end points aligned together and said second end points aligned together in a substantially parallel relationship to said first end points, each of said contacts having a thickness less than ten thousandths (0.010) of an inch; and
a plurality of insulators each separately interposed between each of said contacts to electrically isolate each of said contacts, each of said insulators having a thickness less than ten thousandths (0.010) of an inch.

Abstract
An electrical connector includes a plurality of elongated electrically conductive contacts which are arranged in a side-by-side relationship to establish a first row of end points which is substantially parallel to a second row of end points. A plurality of dielectric insulators are provided and are respectively positioned between the contacts to electrically isolate the individual contacts from each other. Additionally, the contacts are flexible to permit relative movement between end points on the first row and end points on the second row. The combination of stacked contacts and isolating insulators are held on a base to complete a plurality of electrical connections between circuits engaged with end points on the first row and circuits engaged with end points on the second row.
