Abstract
Abstract A housing for interfacing a fiber optic cable with a semiconductor device allows simple insertion and removal of the cable by application of an axial force. The housing exerts a spring-like gripping force upon the cable and axially aligns the cable to the semiconductor device in order to minimize loss of transmitted light. A portion of the gripping force is translated into an axial force by a slanted ridge within the housing which acts upon a ridge on the cable to cause the cable to be forcefully abutted to the semiconductor device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
An apparatus for interfacing a semiconductor device to a fiber optic cable having an annular ridge, said apparatus comprising a housing having: a containment section for containing the semiconductor device; first and second opposed and spreadable jaws extending from the containment section; a slot formed by the jaws and being in axial alignment with the containment section, said slot being operative for receiving and axially aligning the fiber optic cable with the semiconductor device; and an annular gap disposed around a portion of the slot and formed by the first and second jaws, the annular gap being bounded on an anterior side by a slanted ridge which is operative for exerting an axial tractive force upon the annular ridge of the fiber optic cable such that the fiber optic cable is seated against the semiconductor device.
Claim 2
Independent Claim
136 words
An apparatus for interfacing a semiconductor device to a fiber optic cable having an annular ridge, said apparatus comprising a housing having: a containment section for containing the semiconductor device; first and second opposed and spreadable jaws extending from the containment section; a slot formed by the jaws and being in axial alignment with the containment section, said slot being operative for receiving and axially aligning the fiber optic cable with the semiconductor device; and an annular gap disposed around a portion of the slot and formed by the first and second jaws, the annular gap being bounded on an anterior side by a slanted ridge which is operative for exerting an axial tractive force upon the annular ridge of the fiber optic cable such that the fiber optic cable is seated against the semiconductor device.
Claim 3
Dependent Claim
37 words
An apparatus as in claim 1, wherein the slot further comprises a conical depression which is operative for receiving a conical tip of the fiber optic cable and for seating the conical tip against the semiconductor device.
Claim 4
Dependent Claim
38 words
An apparatus as in claim 2, wherein: the slot has an unspread inner diameter; and the annular ridge of the fiber optic cable has an outer diameter which is larger than the unspread inner diameter of the slot.
Claim 5
Dependent Claim
39 words
An apparatus as in claim 3, wherein: the fiber optic cable terminates in a conical section; and, a portion of the slot nearest the semiconductor device comprises a conical slot having substantially the same shape as the conical section.
Claim 6
Dependent Claim
23 words
An apparatus as in claim 4, wherein a lens is located within the housing between the fiber optic cable and the semiconductor device.
Claim 7
Dependent Claim
27 words
An apparatus as in claim 5, wherein the housing further comprises one or more cavities for the protrusion of one or more leads from the semiconductor device.
