Abstract
Abstract Disclosed is a printed circuit board interconnect system having moisture seal means for precluding the formation of a moisture film between electrical contacts. The seal means comprises a resilient seal strip having one or more integral hollow seals disposed on either side thereof, each hollow seal surrounding a male connecting pin of the system and being compressed between printed circuit boards that are electrically connected.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
An electrical interconnect system for interconnecting printed circuit boards comprising: a printed circuit interconnect board having a plurality of electrical male connecting pins extending perpendicularly therefrom; resilient seal means of electrically insulating material surrounding each of said connecting pins said resilient seal means comprising a carrier strip having integral hollow seals on either side thereof, each seal on one side of the strip having its axis aligned with the axis of one of the seals on the other side of the strip, with each aligned axis of opposite seals passing through a hole in said strip, and wherein each of said connecting pins pass through one of said holes in the seal to frictionally engage said carrier strip; and a printed circuit component board having at least one dielectric contact housing mounted thereon, each said housing containing a plurality of spaced electrical socket means, each of said socket means including spring biased electrical contact means frictionally receiving one of said male connecting pins such that said interconnect board and said printed circuit component board are held in spaced relationship with said seal means compressed between said interconnect board and said housing.
Claim 2
Dependent Claim
191 words
An electrical interconnect system for interconnecting printed circuit boards comprising: a printed circuit interconnect board having a plurality of electrical male connecting pins extending perpendicularly therefrom; resilient seal means of electrically insulating material surrounding each of said connecting pins said resilient seal means comprising a carrier strip having integral hollow seals on either side thereof, each seal on one side of the strip having its axis aligned with the axis of one of the seals on the other side of the strip, with each aligned axis of opposite seals passing through a hole in said strip, and wherein each of said connecting pins pass through one of said holes in the seal to frictionally engage said carrier strip; and a printed circuit component board having at least one dielectric contact housing mounted thereon, each said housing containing a plurality of spaced electrical socket means, each of said socket means including spring biased electrical contact means frictionally receiving one of said male connecting pins such that said interconnect board and said printed circuit component board are held in spaced relationship with said seal means compressed between said interconnect board and said housing.
Claim 3
Dependent Claim
45 words
An electrical interconnect system as in claim 1 wherein each of said seals on said one side of the carrier strip is generally cylindrical in shape and each of the seals on the other side of said strip has the shape of two inverted frustums.
Claim 4
Dependent Claim
43 words
An electrical interconnect system as in claim 1 wherein each of said seals on said one side of said strip are rectangular in shape and each of said seals on the other side of said strip have the shape of two inverted frustums.
Claim 5
Dependent Claim
234 words
An electrical interconnect system for interconnecting printed circuit boards comprising: a printed circuit board having a plurality of electrical male connecting pins extending perpendicularly therefrom; a plurality of printed circuit component boards each having at least one dielectric housing mounted thereon, each said housing containing a plurality of spaced electrical socket means, each of said socket means including spring biased electrical contact means forming an opening for receiving a male connecting pin, each of said component boards having an opening therethrough in alignment with the opening in each of said socket means, each of said component boards and said interconnect board being aligned in parallel relationship and having said connecting pins inserted through said holes in said sockets and said boards; and resilient seal means of electrical insulating material surrounding each of said connecting pins between adjacent parallel boards said resilient seal means comprising a carrier strip having integral hollow seals on eitherside thereof, each seal on one side of the strip having its axis aligned with the axis of one of the sEals on the other side of the strip, with each aligned axis of opposite seals passing through a hole in said strip, and wherein each of said connecting pins passes through one of said holes in the seal, said sockets and said connecting pins holding said parallel boards in such relationship that each of said seals is compressed between said boards.
Claim 6
Dependent Claim
234 words
An electrical interconnect system for interconnecting printed circuit boards comprising: a printed circuit board having a plurality of electrical male connecting pins extending perpendicularly therefrom; a plurality of printed circuit component boards each having at least one dielectric housing mounted thereon, each said housing containing a plurality of spaced electrical socket means, each of said socket means including spring biased electrical contact means forming an opening for receiving a male connecting pin, each of said component boards having an opening therethrough in alignment with the opening in each of said socket means, each of said component boards and said interconnect board being aligned in parallel relationship and having said connecting pins inserted through said holes in said sockets and said boards; and resilient seal means of electrical insulating material surrounding each of said connecting pins between adjacent parallel boards said resilient seal means comprising a carrier strip having integral hollow seals on eitherside thereof, each seal on one side of the strip having its axis aligned with the axis of one of the sEals on the other side of the strip, with each aligned axis of opposite seals passing through a hole in said strip, and wherein each of said connecting pins passes through one of said holes in the seal, said sockets and said connecting pins holding said parallel boards in such relationship that each of said seals is compressed between said boards.
Claim 7
Dependent Claim
44 words
An electrical interconnect system as in claim 4 wherein each of said seals on one side of the carrier strip is generally cylindrical in shape and each of the seals on the other side of said strip has the shape of two inverted frustums.
Claim 8
Dependent Claim
42 words
An electrical interconnect system as in claim 4 wherein each of said seals on one side of said strip is rectangular in shape and each of said seals on the other side of said strip has the shape of two inverted frustums.
