Abstract
Abstract Plated-through-holes of printed circuit boards are segmented to provide a plurality of conductors. Matching connector pins having insulating cores and patterned conductive portions are mated with the conductors of the plated-through-holes. Each of the conductors of the holes can be connected to a different one of the patterns on the printed circuit boards thus forming a high density interconnect system.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
130 words
A high density interconnect system comprising: a first electrical circuit board having an insulating substrate with a plurality of discrete electrically conductive patterns formed thereon; at least one plated-through hole formed in said substrate within, and electrically connected to, one of said electrically conducting patterns, said plated-through-hole being segmented to provide at least first and second electrical conductors; and a duplex terminal pin within said plated-through-hole, said terminal pin having an electrically insulating core and first and second electrically conductive portions, said first portion being in electrical contact with said first conductor and said second portion being in electrical contact with said second conductor, one end of said duplex terminal pin being formed as a female receptacle with said portions arranged for receiving and electrically engaging a male contact pin.
