Abstract
Abstract Disclosed in an electrical interconnect system for electrically interconnecting printed circuit component boards. Each component board has mounted thereon an elongated dielectric housing which contains within housing cavities two rows of electrical sockets, the sockets of one row having integral tabs extending over the sockets of the inner row to make electrical connection with circuitry on the board. A resilient seal is provided between the tabs and the inner row sockets to assure moisture isolation and electrical isolation therebetween.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
177 words
An electrical interconnect system comprising: a printed circuit board; an elongated dielectric housing mounted on said board and having an inner and outer row of cavities therein; a plurality of electrical contacts located within cavities in said inner row, each said contact of said inner row having an integral part thereof extending from a first side of said housing and electrically connected to circuitry on said board; a plurality of electrical contacts located within said cavities in said outer row, each contact having an integral tab extending from a second side of said housing opposite said first side, said tab overlying one of the cavities in said first row and electrically connected to circuitry on said board; and a resilient electrical insulator, comprised of a carrier strip of resilient soft rubber having integral projections thereon which extend into each of the cavities of said inner row, compressed between said tab and said second side of said connector to provide a moisture seal and electrical insulator between said tab and the contact in the cavity underlying said tab.
