Abstract
Abstract In interfacing electronic and optical components, a housing fixedly supports a female electrical contact therein, remote from a housing entry aperture. A fiber optic assembly includes a fiber, a transducer terminating the fiber and a ferrule securing the fiber to the transducer. The transducer has a male electrical contact matable with the housing female contact and the fiber optic assembly is configured to pass freely through the housing entry aperture to mate the contacts, thereby providing any desired length of electromagnetic radiation-free path within the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
Optoelectronic apparatus comprising a housing having an upstanding wall defining an entry aperture, said housing supporting a first disconnect electrical contact distal from said wall and interiorly of said entry aperture, and a fiber optic assembly including a fiber optic cable, transducer means for conversion between light and electrical energy in registry with said cable, a second disconnect electrical contact coupled to said transducer means and configured to couple to said first disconnect electrical contact, and ferrule means for securing said cable and said transducer means to one another, said fiber optic assembly being of cross-section less than the cross-section of said entry aperture, whereby said fiber optic assembly is insertable through said entry aperture and said second disconnect contact may be coupled to said first disconnect contact within said housing remotely from said entry aperture.
Claim 2
Dependent Claim
136 words
Optoelectronic apparatus comprising a housing having an upstanding wall defining an entry aperture, said housing supporting a first disconnect electrical contact distal from said wall and interiorly of said entry aperture, and a fiber optic assembly including a fiber optic cable, transducer means for conversion between light and electrical energy in registry with said cable, a second disconnect electrical contact coupled to said transducer means and configured to couple to said first disconnect electrical contact, and ferrule means for securing said cable and said transducer means to one another, said fiber optic assembly being of cross-section less than the cross-section of said entry aperture, whereby said fiber optic assembly is insertable through said entry aperture and said second disconnect contact may be coupled to said first disconnect contact within said housing remotely from said entry aperture.
Claim 3
Dependent Claim
35 words
The apparatus claimed in claim 1 further including guide duct means for said fiber optic assembly, said guide duct means extending interiorly of said housing from said housing wall to said first disconnect electrical contact.
Claim 4
Dependent Claim
27 words
The apparatus claimed in claim 1 further including means releasably securable to said cable and seatable in said entry aperture for providing strain relief for said cable.
Claim 5
Dependent Claim
23 words
The apparatus claimed in claim 1 wherein said ferrule means engages exterior surface of said cable and exterior surface of said transducer means.
Claim 6
Dependent Claim
36 words
