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: 13
Claim 1
Independent Claim
140 words
A resilient seal strip for use in printed circuit board interconnect systems comprising: a resilient carrier strip; a plurality of protrusions integral with said strip extending from the first side of said strip and defining a first plurality of hollow seals of predetermined spacing; and a plurality of protrusions integral with said strip extending from the second side of said strip and defining a second plurality of resilient collapsible low spring rate hollow seals, each one of the seals of said first plurality having a common axis with one of the seals of said second plurality, each said common axis passing through a hole in said strip, the maximum diameter of each hole being substantially less than the interior diameter of each of the hollow seals of said second plurality at the junction of the seals and said carrier strip.
Claim 2
Dependent Claim
140 words
A resilient seal strip for use in printed circuit board interconnect systems comprising: a resilient carrier strip; a plurality of protrusions integral with said strip extending from the first side of said strip and defining a first plurality of hollow seals of predetermined spacing; and a plurality of protrusions integral with said strip extending from the second side of said strip and defining a second plurality of resilient collapsible low spring rate hollow seals, each one of the seals of said first plurality having a common axis with one of the seals of said second plurality, each said common axis passing through a hole in said strip, the maximum diameter of each hole being substantially less than the interior diameter of each of the hollow seals of said second plurality at the junction of the seals and said carrier strip.
Claim 3
Dependent Claim
19 words
The seal strip of claim 1 in which the hollow seals of said first plurality are rectangular in shape.
Claim 4
Dependent Claim
19 words
The seal strip of claim 1 in which the hollow seals of said first plurality are cylindrical in shape.
Claim 5
Dependent Claim
19 words
The seal strip of claim 1 in which the hollow seals of said second plurality are cylindrical in shape.
Claim 6
Dependent Claim
22 words
The seal strip of claim 1 in which the hollow seals of said second plurality are in the shape of a frustum.
Claim 7
Dependent Claim
25 words
The seal strip of claim 1 in which the hollow seals of said second plurality of seals are in the shape of two inverted frustums.
Claim 8
Dependent Claim
48 words
The seal strip of claim 1 in which the interior diameter of each seal of said second plurality of seals at the junction with the carrier strip and the point farthest removed from the carrier strip is in each instance substantially less than the maximum interior diameter thereof.
Claim 9
Dependent Claim
45 words
The seal strip of claim 1 wherein the interior diameter of each seal of said second plurality of seals at the junction of said carrier strip is substantially less than the interior diameter of each seal of said first plurality of seals at said junction.
Claim 10
Dependent Claim
132 words
A resilient seal strip for use in printed circuit interconnect systems comprising: a resilient carrier strip; a first plurality of resilient hollow and generally cylindrical seals of predetermined spacing integral with said strip and extending from a first side of said strip; and a second plurality of resilient integral hollow seals in the shape of two inverted frustums extending from and integral with the second side of said strip, each one of the hollow seals of said first plurality having a common axis with one of the hollow seals of said second plurality, each said common axis passing through the center of a hole in said strip, the minimum interior diameter of each hollow seal of said second plurality being substantially larger than the maximum diameter of each hole in said strip.
Claim 11
Dependent Claim
132 words
A resilient seal strip for use in printed circuit interconnect systems comprising: a resilient carrier strip; a first plurality of resilient hollow and generally cylindrical seals of predetermined spacing integral with said strip and extending from a first side of said strip; and a second plurality of resilient integral hollow seals in the shape of two inverted frustums extending from and integral with the second side of said strip, each one of the hollow seals of said first plurality having a common axis with one of the hollow seals of said second plurality, each said common axis passing through the center of a hole in said strip, the minimum interior diameter of each hollow seal of said second plurality being substantially larger than the maximum diameter of each hole in said strip.
Claim 12
Dependent Claim
97 words
A low spring rate resilient seal comprising; a resilient carrier strip; a first hollow and generally cylindrical resilient seal integral with and exTending from a first side of said strip; a second hollow and generally cylindrical resilient seal integral with and extending from a second side of said strip; and a hole extending through said strip between said first and second seals; the axes of said first and second seals and said hole being in alignment, the minimum interior diameter of at least one of said seals being substantially larger than the maximum diameter of said hole.
Claim 13
Dependent Claim
97 words
A low spring rate resilient seal comprising; a resilient carrier strip; a first hollow and generally cylindrical resilient seal integral with and exTending from a first side of said strip; a second hollow and generally cylindrical resilient seal integral with and extending from a second side of said strip; and a hole extending through said strip between said first and second seals; the axes of said first and second seals and said hole being in alignment, the minimum interior diameter of at least one of said seals being substantially larger than the maximum diameter of said hole.
