Abstract
Abstract A hermetic seal is formed of a compound which is applied with low viscosity to a form located between a center contact and a body of a coaxial connector. The compound is cured without heat or pressure by subjecting it to ultraviolet light. The viscous material completely seals the coaxial connector and when hardened forming an excellent hermetic seal. Apparatus for holding the coaxial connectors vertical to receive the compound is also disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A method for forming a hermetic seal without using a glass seal for a coaxial connector which comprises a center contact surrounded by a body, a form configured between said center contact and said body, said non-glass hermetic seal being located in said form, said method comprising the steps of: assembling said center contact, said body and a holder as one unit to provide said form between said center contact and said body, vertically holding said unit on said holder, forming said non-glass hermetic seal by the steps of applying a material consisting essentially of a light curable viscous chemical compound to fill the form between said center contact and said body, and supplying light to said compound to cure said viscous chemical compound and thereby form said non-glass hermetic seal effectively only by said light cured compound.
Claim 2
Independent Claim
138 words
A method for forming a hermetic seal without using a glass seal for a coaxial connector which comprises a center contact surrounded by a body, a form configured between said center contact and said body, said non-glass hermetic seal being located in said form, said method comprising the steps of: assembling said center contact, said body and a holder as one unit to provide said form between said center contact and said body, vertically holding said unit on said holder, forming said non-glass hermetic seal by the steps of applying a material consisting essentially of a light curable viscous chemical compound to fill the form between said center contact and said body, and supplying light to said compound to cure said viscous chemical compound and thereby form said non-glass hermetic seal effectively only by said light cured compound.
Claim 3
Dependent Claim
28 words
A method for forming a hermetic seal as set forth in claim 1, further comprising the step of self-leveling said compound in said form before curing the same.
Claim 4
Dependent Claim
41 words
A method for forming a hermetic seal as set forth in claim 1, further comprising the step of forming a well in said form into which said viscous compound is dropped and completely filling said form and curing said compound therein.
Claim 5
Dependent Claim
28 words
A method for forming a hermetic seal as set forth in claim 3, further comprising the step of self-leveling said compound in said form before curing the same.
Claim 6
Dependent Claim
26 words
A method for forming a hermetic seal as set forth in claim 1, further comprising applying an ultraviolet light to said compound to cure said compound.
Claim 7
Dependent Claim
28 words
A method for forming a hermetic seal as set forth in claim 5, further comprising the step of self-leveling said compound in said form before curing the same.
Claim 8
Dependent Claim
27 words
A method for forming a hermetic seal as set forth in claim 3, wherein said well is formed by forming an annular form in said center contact.
Claim 9
Dependent Claim
28 words
A method for forming a hermetic seal as set forth in claim 7, further comprising the step of self-leveling said compound in said form before curing the same.
Claim 10
Dependent Claim
39 words
A method for forming a hermetic seal as set forth in claim 1, further comprising a holder for holding a plurality of said coaxial connectors permitting one after another of said coaxial connectors to be filled with said comound.
Claim 11
Dependent Claim
28 words
A method for forming a hermetic seal as set forth in claim 9, further comprising the step of self-leveling said compound in said form before curing the same.
