Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A cylindrical electronic packaging arrangement comprising a plurality of elongated cylinders of different diameters and having electronic components mounted on surfaces thereof with output leads from the surfaces located at the ends of the cylinders, insulating spacer means between the cylinders and being keyed to the cylinders to space the cylinders relative to each other, an end cap over the end of the cylinders at each end and having connector pins connected through connector means to innerconnect the output leads with the connector pins in the end cap to connect the electronic components out through said end cap, and said end cap being sealed relative to said cylinders.
Claim 2
Dependent Claim
108 words
A cylindrical electronic packaging arrangement comprising a plurality of elongated cylinders of different diameters and having electronic components mounted on surfaces thereof with output leads from the surfaces located at the ends of the cylinders, insulating spacer means between the cylinders and being keyed to the cylinders to space the cylinders relative to each other, an end cap over the end of the cylinders at each end and having connector pins connected through connector means to innerconnect the output leads with the connector pins in the end cap to connect the electronic components out through said end cap, and said end cap being sealed relative to said cylinders.
Claim 3
Dependent Claim
48 words
A cylindrical packaging arrangement as set forth in claim 1, wherein said insulating spacer means includes a ring between each cylinder at each end of the cylinders and having projections thereon for mating with grooves in the cylinders for spacing and mounting the cylinders relative to each other.
Claim 4
Dependent Claim
36 words
A cylindrical packaging arrangement as set forth in claim 2, wherein said end cap has solder mounted therein that solders the end cap relative to said cylinders to seal said end cap relative to said cylinders.
Claim 5
Dependent Claim
51 words
A cylindrical packaging assembly as set forth in claim 1, wherein said connector means for connecting between said pins and said output leads includes a connector ring that is made of insulating resilient material with circuits mounted on the surface of said ring for innerconnecting the output leads to said pins.
Claim 6
Dependent Claim
33 words
A cylindrical packaging assembly as set forth in claim 1, wherein said connector means includes spring contacts which are integral with said pins and said spring contacts making contact with said output leads.
