Device for an optical-fiber connection
View Patent ↗Device for the coaxial connection of fiber-optic cables, comprising a single-piece coupling housing ( 10 ) and a single-piece sleeve mount ( 20 ), the sleeve mount ( 20 ) being designed with at least one latching nose ( 21 ) and the coupling housing ( 10 ) being designed with at least one latching mount which complements the at least one latching nose ( 21 ), wherein the latching mount is designed with at least one latching hook ( 14 ) and at least one stop ( 15 ).
1. A fiber optic coupling for interconnecting first and second fiber optic connectors in coaxial alignment, each connector including a generally cylindrical ferrule holding an end of an optical fiber, the coupling comprising:
a coupling housing including an axial passage defined by a top wall, a bottom wall, a right wall, and a left wall, the axial passage extending between a first opening defined at a first end of the coupling housing and a second opening defined at a second end of the coupling housing, the first end configured to receive the first fiber optic connector through the first opening and the second end configured to receive the second fiber optic connector through the second opening for mating with the first fiber optic connector; and
a ferrule alignment structure located within the axial passage, the ferrule alignment structure including a sleeve mount defining a first end, a second end, and a center portion, wherein the first end of the sleeve mount is positioned toward the first end of the coupling housing and the second end of the sleeve mount is positioned toward the second end of the coupling housing, the sleeve mount further defining an axial bore that defines a longitudinal axis extending from the first end of the sleeve mount toward the second end of the sleeve mount, the axial bore configured to receive and coaxially align the ferrules of the first and second fiber optic connectors when the connectors are inserted into the fiber optic coupling, wherein the sleeve mount includes a first portion extending from the center portion of the sleeve mount toward the first end of the sleeve mount and a second portion extending from the center portion of the sleeve mount toward the second end of the sleeve mount, each of the first and second portions defining an inwardly extending finger for capturing a ferrule sleeve within the axial bore, the inwardly extending finger of the first portion being positioned around the axial bore at a peripherally offset relationship with respect to the inwardly extending finger of the second portion along the longitudinal axis defined by the axial bore.
2. A fiber optic coupling according to claim 1 , wherein each of the first portion and the second portion of the sleeve mount includes three inwardly extending fingers.
3. A fiber optic coupling according to claim 1 , wherein the sleeve mount is removably inserted into the coupling housing.
4. A fiber optic coupling according to claim 3 , wherein the sleeve mount and the coupling housing are configured such that the sleeve mount is inserted into the axial passage of the coupling housing in a direction parallel to the longitudinal axis.
5. A fiber optic coupling according to claim 1 , wherein the fiber optic coupling is configured for interconnecting two SC type fiber optic connectors in coaxial alignment.
6. A fiber optic coupling according to claim 1 , wherein the coupling housing defines a mounting flange outwardly protruding from each of the right wall and the left wall.
7. A fiber optic coupling according to claim 1 , wherein the sleeve mount is configured such that the ferrule sleeve is inserted into the sleeve mount in a direction along the longitudinal axis.
8. A fiber optic coupling according to claim 1 , wherein at least one of the first portion and the second portion of the sleeve mount defines flexible arms defined around the axial bore of the sleeve mount for receiving a ferrule sleeve, the flexible arms configured to flex out radially to receive the ferrule sleeve into the axial bore.
9. A fiber optic coupling according to claim 8 , wherein the at least one portion defines three of the flexible arms.
10. A fiber optic coupling according to claim 8 , wherein the flexible arms extend in a direction from the center portion of the sleeve mount toward at least one of the first end and the second end of the sleeve mount.
11. A fiber optic coupling according to claim 10 , wherein the inwardly extending fingers are positioned on the flexible arms.
12. A fiber optic coupling according to claim 1 , wherein the top wall of the coupling housing defines a keying groove at each of the first and second ends thereof configured to intermate with complementary keying tongues of the first and second fiber optic connectors to orient the first and second fiber optic connectors in a correct orientation.
13. A fiber optic coupling according to claim 1 , wherein the sleeve mount includes two latching hooks extending from the center portion of the sleeve mount toward the first end of the coupling housing and two latching hooks extending from the center portion of the sleeve mount toward the second end of the coupling housing, wherein the latching hooks extending toward the first end of the coupling housing are positioned on opposite sides of the axial bore and are configured to flex toward and away from each other to releasably latch the first fiber optic connector to the fiber optic coupling and the latching hooks extending toward the second end of the coupling housing are positioned on opposite sides of the axial bore and are configured to flex toward and away from each other to releasably latch the second fiber optic connector to the fiber optic coupling.
14. A fiber optic coupling according to claim 13 , wherein the latching hooks include inwardly extending portions configured to engage the first and second fiber optic connectors.
