Fiber optic device coupling

Claim 2

A fiber optic device coupling for connecting an optical fiber cable to an electro-optical device comprising: a housing having a pasasge therethrough opening at the opposite ends of said housing; one end of said passage being adapted to receive an electro-optical device therein having an active face disposed toward the other end of said passage; a fiber optic contact mounted in the opposite end of said passage, said contact having a forward mating end face and a rear end, said rear being adapted to be connected to a fiber optic cable; radially movable, resilient contact retention means extending between said contact and the wall of said passage for releasably retaining said contact in said passage; a forwardly facing shoulder on said contact; a shoulder on the wall of said passage facing said contact shoulder and spaced therefrom; and resilient means compressed between said shoulders serving to prevent said forward mating end face of said contact from forcibly engaging the active face of an electro-optical device mounted in said one end of said passage, said compressed resilient means having sufficient resilience to substantially prevent longitudinal rattle of said contact within said passage.

Claim 3

A coupling as set forth in claim 1 wherein: said contact embodies a rearwardly facing shoulder behind said forwardly facing shoulder; and said contact retention means comprises a resilient finger extending inwardly from the wall of said passage in the direction toward said one end of said passage, said finger having a free end engaging said rearwardly facing shoulder.

Claim 4

A coupling as set forth in claim 2 wherein: said resilient means urges said contact rearwardly facing shoulder against said free end of said finger.

Claim 5

A coupling as set forth in claim 3 wherein: said resilient means is an O-ring.

Claim 6

A fiber optic device coupling comprising: a housing having a passage therethrough opening at the opposite ends of said housing; an electro-optical device mounted in one end of said passage, said device having an active face disposed toward the other end of said passage; a fiber optic contact mounted in the opposite end of said passage, said contact having a forward mating end face and a rear end, said rear end being adapted to be connected to a fiber optic cable, said mating end face being slightly spaced from said active face of said device; radially movable, resilient contact retention means extending between said contact and the wall of said passage for releasably retaining said contact in said passage; a forwardly facing shoulder on said contact; a shoulder on the wall of said passage facing said contact shoulder and spaced therefrom; and resilient means compressed between said shoulders serving to prevent said forward mating end face of said contact from forcibly engaging said active face of said device when said coupling is subjected to vibration, said compressed resilient means having sufficient resilience to substantially prevent longitudinal rattle of said contact within said passage.

Claim 7

A fiber optic device coupling comprising: a housing having a passage therethrough opening at the opposite ends of said housing; an electro-optical device mounted in one end of said passage, said device having an active face disposed toward the other end of said passage; a fiber optic contact mounted in the opposite end of said passage, said contact having a forward mating end face and a rear end, said rear end being adapted to be connected to a fiber optic cable, said mating end face being slightly spaced from said active face of said device; radially movable, resilient contact retention means extending between said contact and the wall of said passage for releasably retaining said contact in said passage; a forwardly facing shoulder on said contact; a shoulder on the wall of said passage facing said contact shoulder and spaced therefrom; and resilient means compressed between said shoulders serving to prevent said forward mating end face of said contact from forcibly engaging said active face of said device when said coupling is subjected to vibration, said compressed resilient means having sufficient resilience to substantially prevent longitudinal rattle of said contact within said passage.

Claim 8

A fiber optic device coupling for connecting an optical fiber cable to an electro-optical device comprising: a housing having a pasasge therethrough opening at the opposite ends of said housing; one end of said passage being adapted to receive an electro-optical device therein having an active face disposed toward the other end of said passage; a fiber optic contact mounted in the opposite end of said passage, said contact having a forward mating end face and a rear end, said rear end being adapted to be connected to a fiber optic cable; said contact having forwardly and rearwardly facing shoulders thereon; a radially movable, resilient contact retention finger extending inwardly from the wall of said passage and engaging said rearwardly facing shoulder on said contact in said passage; a shoulder on the wall of said passage in front of and facing said contact forwardly facing shoulder and spaced therefrom; resilient means disposed between said contact forwardly facing shoulder and the shoulder on the wall of said passage serving to prevent said forward mating end face of said contact from forcibly engaging the active face of an electro-optical device mounted in said one end of said passage; and said resilient means being compressed between said contact fowardly facing shoulder and said shoulder on the wall of said passage, whereby said contact rearwardly facing shoulder is resiliently urged against said contact retention finger to substantially prevent longitudinal rattle of said contact within said passage.

Claim 9

A fiber optic device coupling for connecting an optical fiber cable to an electro-optical device comprising: a housing having a pasasge therethrough opening at the opposite ends of said housing; one end of said passage being adapted to receive an electro-optical device therein having an active face disposed toward the other end of said passage; a fiber optic contact mounted in the opposite end of said passage, said contact having a forward mating end face and a rear end, said rear end being adapted to be connected to a fiber optic cable; said contact having forwardly and rearwardly facing shoulders thereon; a radially movable, resilient contact retention finger extending inwardly from the wall of said passage and engaging said rearwardly facing shoulder on said contact in said passage; a shoulder on the wall of said passage in front of and facing said contact forwardly facing shoulder and spaced therefrom; resilient means disposed between said contact forwardly facing shoulder and the shoulder on the wall of said passage serving to prevent said forward mating end face of said contact from forcibly engaging the active face of an electro-optical device mounted in said one end of said passage; and said resilient means being compressed between said contact fowardly facing shoulder and said shoulder on the wall of said passage, whereby said contact rearwardly facing shoulder is resiliently urged against said contact retention finger to substantially prevent longitudinal rattle of said contact within said passage.
