Abstract
Abstract A rivet is utilized for both internal and external contact in electronic components, particularly in electrolytic capacitor seals. At least two leads egress from the same opening in the capacitor container and the rivets are recessed within an elastomeric seal member to avoid shorting the lead wires against one another.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
150 words
An electrical component seal comprising: an electrical component container having an opening therein; a component body placed therein, said component body having at least two component lead members extending therefrom; a seal member within said opening comprising an elastomeric member; said elastomeric member having at least two openings therein; rivet members within said openings in said elastomer having a lower flange portion which engages the bottom of said elastomeric members, and an upper flange portion which is recessed from the upper surface of said elastomer, said flange members extending into said elastomeric material to provide in conjunction with said elastomeric members a sealing of said component body from the atmosphere; said component leads being welded to the lower portion of said lower flange member to provide electrical connection of said component body and an external circuit; and at least two external leads welded to the upper portion of said rivet.
Claim 2
Dependent Claim
150 words
An electrical component seal comprising: an electrical component container having an opening therein; a component body placed therein, said component body having at least two component lead members extending therefrom; a seal member within said opening comprising an elastomeric member; said elastomeric member having at least two openings therein; rivet members within said openings in said elastomer having a lower flange portion which engages the bottom of said elastomeric members, and an upper flange portion which is recessed from the upper surface of said elastomer, said flange members extending into said elastomeric material to provide in conjunction with said elastomeric members a sealing of said component body from the atmosphere; said component leads being welded to the lower portion of said lower flange member to provide electrical connection of said component body and an external circuit; and at least two external leads welded to the upper portion of said rivet.
