Fiber optic connector with unitary housing and fiber optic connector assembly
Fiber optic connectors, including SC connectors having a unitary housing that supports a ferrule and also allows for disengagement and release of the connector from, e.g., an adapter. The unitary housing includes a pair of release arms pivotal relative to a main body of the unitary housing, where pivoting of the release arms enables engagement and disengagement of corresponding latch arms in an adapter, for example.
1. A fiber optic connector, comprising:
a unitary housing having a main body defining a central axis and supporting a ferrule adapted to terminate an optical fiber, the unitary housing including a pair of opposing sides, each of the pair of opposing sides defining a protruding catch, the unitary housing further comprising a release arm pivotally coupled to each of the opposing sides of the main body, the release arms being configured such that when the unitary housing is inserted in a fiber optic adapter, applying a force on each release arm towards the central axis pushes a latching arm of the fiber optic adapter away from the central axis.
2. The fiber optic connector of claim 1 , wherein each of the release arms includes an integral release bar that pivots with the release arm.
3. The fiber optic connector of claim 2 , wherein each of the release arms includes a pair of substantially parallel fingers, and wherein the release bar extends between the two substantially parallel fingers.
4. The fiber optic connector of claim 3 , wherein the fingers and the release bar on each side of the unitary housing define a window surrounding the protruding catch.
5. The fiber optic connector of claim 1 , further comprising a pivoting joint between each release arm and the corresponding side of the main body of the unitary housing, wherein each of the release arms is pivotal about one of the pivoting joints between a latching position and a release position.
6. The fiber optic connector of claim 1 , wherein each of the release arms includes a wing extending away from the main body of the housing and adapted to facilitate pivoting of the release arm.
7. The fiber optic connector of claim 1 , wherein the main body supports a spring for axially biasing the ferrule within the main body along the central axis.
8. The fiber optic connector of claim 1 , wherein the fiber optic connector does not include a spring for axially biasing the ferrule along the central axis.
9. The fiber optic connector of claim 1 , wherein a ferrule hub of the ferrule engages a flexibly resilient flange within a cavity defined by the main body.
10. The fiber optic connector of claim 1 , wherein the unitary housing defines:
a forward plug region defining a plug cavity;
a tail region through which the optical fiber is inserted into the housing and about which can be secured a strain relief boot; and
an intermediate region between the plug region and the tail region, the intermediate region defining an internal cavity.
11. The fiber optic connector of claim 10 , wherein the intermediate region is a splice region defining the internal cavity within the unitary housing for supporting a splice.
12. The fiber optic connector of claim 1 , wherein the unitary housing does not support a splice.
13. The fiber optic connector of claim 10 , wherein the tail region includes an integral hollow tail axially extending from a back of the main body along the central axis, the integral hollow tail being adapted to couple to the strain relief boot.
14. The fiber optic connector of claim 13 , wherein the integral hollow tail includes a crimping tab pressable into an interior hollow space of the integral hollow tail.
15. The fiber optic connector of claim 1 , wherein the fiber optic connector is a TIA FOCIS 3-compliant SC connector.
16. An assembly including a TIA FOCIS 3-compliant SC adapter and a fiber optic connector according to claim 1 ,
wherein the protruding catches releasably engage a pair of latch arms of the SC adapter.
17. The assembly of claim 16 , wherein the release arms are adapted to pivot to push apart the latch arms of the SC adapter away from the central axis to disengage the latch arms from the protruding catches.
18. The assembly of claim 16 , wherein the adapter comprises a main body defining first and second connector sockets each adapted to receive a housing of a connector.
19. The assembly of claim 16 , wherein the adapter is supported in optical distribution equipment.
20. A method of removing a fiber optic connector from optical distribution equipment, comprising:
applying force to a pair of release arms of the fiber optic connector to pivot the release arms about pivot joints of a unitary housing that includes the release arms and also supports a fiber optic ferrule, the force being applied towards a central axis of the fiber optic connector, the applied force causing release bars of the unitary housing to push latching arms of the optical distribution equipment away from the central axis.
21. The method of claim 20 , further comprising pulling, subsequent to the applied force, the unitary housing out of the optical distribution equipment.
22. The method of claim 20 , wherein the applied force causes protrusions of latching arms of the optical distribution equipment to disengage protruding catches of the fiber optic connector.
23. The method of claim 20 , wherein the optical distribution equipment is a TIA FOCIS 3-compliant SC adapter.
24. The method of claim 20 , wherein the fiber optic connector is TIA FOCIS 3-compliant SC connector.
