Abstract

Fiber optic connectors and connectorized fiber optic cables include connector housings having locking portions defined on the connector housing that allow the connector housing to be selectively coupled to a corresponding push-button securing member of a multiport assembly. Methods for selectively connecting a fiber optic connector to, and disconnecting the fiber optic connector from the multiport assemblies allow for connector housings to be forcibly and nondestructively removed from the multiport assembly.

First claim

What is claimed is:

1. A multiport assembly comprising:
a shell defining a cavity positioned within the shell;
a plurality of optical adapters positioned within the cavity of the shell, the optical adapters structurally configured to receive, align, and optically couple dissimilar optical connectors;
a plurality of optical connection ports comprising respective connection port passageways permitting external optical connectors to access the plurality of optical adapters positioned within the cavity of the shell, the connection port passageways comprising respective connector insertion paths; and
a plurality of push-button securing members associated with respective ones of the connection port passageways, wherein
each push-button securing member is biased in an engaged position, in which a locking portion of the push-button securing member is positioned within a corresponding connector insertion path, and is selectively positionable into and out of a disengaged position, in which the locking portion of the push-button securing member is positioned outside the corresponding connector insertion path, and
the locking portion of each push-button securing member is configured to permit forcible nondestructive disengagement of an external optical connector from the locking portion of the push-button securing member upon application of a force on the external optical connector in a direction along an axis extending along the corresponding connector insertion path.

2. The multiport assembly of claim 1 , further comprising a plurality of resilient members each engaged with a corresponding push-button securing member, wherein the plurality of resilient members each bias the corresponding push-button securing member into the engaged position.

3. The multiport assembly of claim 2 , wherein each of the plurality of resilient members has a spring constant of between 10 newtons per millimeter and 50 newtons per millimeter.

4. The multiport assembly of claim 2 , wherein the plurality of push-button securing members are each moved to the disengaged position upon the application of the force on the external optical connector exceeding a predetermined threshold between 20 newtons and 500 newtons.

5. The multiport assembly of claim 4 , wherein the plurality of push-button securing members are each moved to the disengaged position under a force exceeding a predetermined threshold between 5 newtons and 50 newtons applied to the push-button securing member in a direction that is transverse to the axis extending along the corresponding connector insertion path.

6. The multiport assembly of claim 2 , wherein each of the plurality of resilient members has a free length of between 3 millimeters and 20 millimeters.

7. The multiport assembly of claim 2 , wherein each of the plurality of resilient members has a free length of at least 0.75 millimeters.

8. The multiport assembly of claim 1 , wherein each of the plurality of push-button securing members comprise a bore extending through the push-button securing member.

9. The multiport assembly of claim 8 , wherein the locking portion of each of the plurality of push-button securing members comprise a connector engagement face positioned on the bore and oriented transverse to the corresponding connector insertion path.

10. The multiport assembly of claim 9 , wherein the connector engagement face of each of the plurality of push-button securing members is positioned within the corresponding connector insertion path when the push-button securing member is in the engaged position, and the connector engagement face is spaced apart from the corresponding connector insertion path when the push-button securing member is in the disengaged position.

11. The multiport assembly of claim 10 , wherein the each of the plurality of push-button securing members is moved to the disengaged position upon the application of the force on the external optical connector exceeding a predetermined threshold between 20 newtons and 500 newtons.

12. The multiport assembly of claim 10 , wherein the bore defines an inner perimeter, and the connector engagement face extends inward from the inner perimeter of the bore.

13. The multiport assembly of claim 12 , wherein:
the connector engagement face of each of the plurality of push-button securing members comprises an inner end and an outer end positioned outward of the inner end; and
the push-button securing member further comprises a ramp positioned on the bore, the ramp extending between the inner perimeter of the bore and the inner end of the connector engagement face.

14. The multiport assembly of claim 13 , wherein:
the plurality of optical connection ports are positioned at a front end of the multiport assembly and the multiport assembly comprises a rear end positioned opposite the front end; and
the ramp is positioned forward of the connector engagement face.

15. The multiport assembly of claim 12 , wherein the connector engagement face of each of the plurality of push-button securing members defines a plane that is perpendicular to the corresponding connector insertion path.

16. The multiport assembly of claim 12 , wherein the plurality of optical connection ports are positioned at a front end of the multiport assembly and the multiport assembly comprises a rear end positioned opposite the front end, and wherein the connector engagement face of each of the plurality of push-button securing members comprises an inner end and an outer end positioned outward of the inner end, and wherein the outer end is positioned closer to the rear end of the multiport assembly than the inner end.

17. The multiport assembly of claim 16 , wherein the connector engagement face of each of the plurality of push-button securing members defines a plane that intersects the corresponding connector insertion path at an angle that is less than 30 degrees from perpendicular.

18. The multiport assembly of claim 1 , wherein each of the plurality of push-button securing members is selectively deformable between the engaged position and the disengaged position.

19. The multiport assembly of claim 1 , wherein the locking portion of each of the plurality of push-button securing members comprise a pair of opposing arms, wherein the pair of opposing arms are selectively deformable outward from the corresponding connector insertion path to reposition the push-button securing member between the engaged position and the disengaged position.

20. The multiport assembly of claim 19 , wherein each of the plurality of push-button securing members further comprise tabs positioned on and extending outward from the pair of opposing arms.

21. The multiport assembly of claim 1 , wherein the shell comprises an upward-facing top surface and the plurality of optical connection ports are positioned on an outward-facing front end of the shell, and the multiport assembly further comprises a plurality of scallops each associated with one of the plurality of connection ports and including a cut-out extending into the outward-facing front end and the top surface.

22. The multiport assembly of claim 1 , wherein adjacent optical connection ports of the plurality of optical connection ports are spaced apart from one another by less than 13 millimeters evaluated between a central axis extending through corresponding adjacent connector insertion paths.

23. A method for selectively connecting a fiber optic connector to a multiport assembly, the method comprising:
inserting a co
