Anti-wiggle optical receptacle
View Patent ↗A casing includes a solid sleeve and a split sleeve in combination to provide a connection between a fiber stub and a ferrule containing an optical fiber. The arrangement prevents wiggle of the ferrule, and also does so without the tight tolerances that would otherwise be required in solid sleeve systems.
1. A device for aligning a connector ferrule with an optical stub, said device comprising a solid sleeve and a split sleeve in series, the solid and split sleeves being surrounded by a casing, a fiber stub being contained within the split sleeve, wherein said casing comprises a spacer between said solid sleeve and said split sleeve, said spacer extending into the space between the split and solid sleeves to prevent either from being pushed into the other,
wherein the spacer has an internal diameter that is smaller than the outer diameter of the split sleeve.
2. The device of claim 1 wherein said spacer includes a flange integrally formed with said casing.
3. The device of claim 1 wherein the spacer is constructed to obstruct longitudinal movement of the split sleeve.
4. The device of claim 1 wherein the spacer is constructed to impinge on an outward longitudinal end of the split sleeve.
5. A device for aligning a connector ferrule with an optical stub, said structure comprising a solid sleeve and a split sleeve in series, the solid and split sleeves being surrounded by a casing, a fiber stub being contained within the split sleeve, wherein said casing comprises a spacer between said solid sleeve and said split sleeve, said spacer extending into the space between the split and solid sleeves to prevent either from being pushed into the other,
wherein said spacer includes a flange integrally formed with said casing; and
wherein said spacer includes at least two walls extending in a direction other than the longitudinal direction of said sleeves.
