Abstract
Abstract A fiber optic feedthrough connector 10, typically mounted in a panel 13 through which contact is to be made, carries a double-ended terminus 47 hermetically sealed, anchored in, and extending through a wall portion 17 of the connector 10. An optic fiber 24 extends axially through the double-ended terminus 47 and is terminated at opposite ends in a pair of alignment bushings 57. Alignment inserts 21, 23 extending from opposite ends of the connector 10 serve both to protect the double-ended terminus 47 and to provide means for keyed engagement with connectors on opposite sides of the panel 13 in which the connector 10 is mounted.

Claim 2
Dependent Claim
50 words
A fiber optic feedthrough connector assembly comprising: a. a housing having a wall disposed therein, and b. elongated fiber optic contact means extending through said wall and terminating at each of its opposite ends in a light coupling surface, said light coupling surfaces being on opposite sides of said wall.
Claim 3
Dependent Claim
22 words
The connector of claim 1 additionally characterized in that said assembly is hermetically sealed where said contact means extends through said wall.
Claim 4
Dependent Claim
23 words
The connector of claim 1 characterized further in that said contact means comprises a double ended terminus having an optic fiber extending therethrough.
Claim 5
Dependent Claim
49 words
The connector of claim 3 characterized further in that said double ended terminus comprises: a. a pin, said optic fiber extending axially along said pin, and b. a bushing at each end of said pin, said optic fiber terminating at its opposite ends in respective ones of said bushings.
Claim 6
Dependent Claim
65 words
The connector of claim 4 characterized further in that said housing comprises: a. a core portion containing said wall and having a pair of threaded receptacles extending in opposite directions from and separated by said wall, and b. a pair of threaded cylindrical inserts threadably coupled to respective ones of said receptacles, said cylindrical inserts protectively extending around and beyond said fiber optic contact means.
Claim 7
Dependent Claim
32 words
The connector of claim 5 characterized further by an alignment sleeve mounted on at least one end of said double ended terminus, said alignment sleeve being entirely within one of said inserts.
Claim 8
Dependent Claim
43 words
The connector of claim 1 characterized further in that said contact means comprises a double ended terminus having an optic fiber extending therethrough and in that said terminus is tipped at each end by an alignment bushing in which said optic fiber terminates.
Claim 9
Dependent Claim
25 words
The connector of claim 7 characterized further in that said double ended terminus is hermetically sealed where it extends through the wall of said housing.
Claim 10
Dependent Claim
46 words
The connector of claim 7 characterized further in that said connector includes a pair of cylindrical inserts extending in opposite directions from a central portion of said housing, each insert surrounding a respective one of the ends of said double ended terminus and the bushing thereon.
Claim 11
Dependent Claim
43 words
The connector of claim 7 characterized further in that said connector includes a pair of alignment sleeves, each mounted on one end of said double ended terminus, and each having an opening for receiving a fiber optic terminus for mating with said connector.
Claim 12
Dependent Claim
44 words
The connector of claim 10 characterized further by a pair of cylindrical inserts extending in opposite directions from a central portion of said housing, each insert surounding a respective one of the ends of said double ended terminus and the alignment sleeve mounted thereon.
Claim 13
Dependent Claim
40 words
The connector of claim 11 characterized further in that said fiber optic contact means comprises a pin, an alignment bushing at each end of said pin, and an optic fiber extending axially through said pin and terminating in said bushings.
Claim 14
Dependent Claim
68 words
An optical feedthrough connector assembly comprising: a housing having a passage extending therethrough; an elongated optical contact means in said passage, said contact means terminating at each of its opposite ends in a light coupling surface; and an alignment sleeve extending into said passage and being carried by said contact means, an end portion of the alignment sleeve extending axially outwardly beyond an end of the contact means.
Claim 15
Dependent Claim
68 words
An optical feedthrough connector assembly comprising: a housing having a passage extending therethrough; an elongated optical contact means in said passage, said contact means terminating at each of its opposite ends in a light coupling surface; and an alignment sleeve extending into said passage and being carried by said contact means, an end portion of the alignment sleeve extending axially outwardly beyond an end of the contact means.
Claim 16
Dependent Claim
47 words
