Abstract

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.

First claim

What is claimed is:

1. A fiber optic connector, comprising:
a housing defining a central axis extending from a rear end of the housing to a front end of the housing, the housing including:
a main body supporting a ferrule positioned at the front end of the housing and adapted to terminate an optical fiber;
a catch protruding away from the main body; and
a release mechanism pivotally connected to the main body at a pivot joint positioned rearward of the catch, the release mechanism including:
fingers extending from the pivot joint;
a release bar extending from one of the fingers to the other of the fingers and positioned forward of the catch, the fingers and the release bar defining a window aligned with the catch along a reference line perpendicular to the central axis; and
an arm portion extending from the pivot joint, the release mechanism being configured such that pushing of the arm portion towards the central axis causes the fingers and the release bar to move away from the central axis.

2. The fiber optic connector of claim 1 ,
wherein the catch is positioned on a first side of the main body; and
wherein the release mechanism is positioned on the first side, the fiber optic connector further comprising, on a second side of the main body opposite the first side:
another catch protruding away from the main body; and
another release mechanism pivotally connected to the main body at another pivot joint positioned rearward of the another catch, the another release mechanism including:
other fingers extending from the another pivot joint;
another release bar extending from one of the another fingers to the other of the another fingers and positioned forward of the catch, the another fingers and the another release bar defining another window aligned with the another catch along the reference line; and

another arm portion extending from the another pivot joint, the another release mechanism being configured such that pushing of the another arm portion towards the central axis causes the other fingers and the another release bar to move away from the central axis.

3. The fiber optic connector of claim 1 , wherein the fingers are parallel to each other and the release bar is perpendicular to the fingers.

4. The fiber optic connector of claim 1 , wherein the arm portion includes a wing extending away from the main body and adapted to facilitate pivoting of the release mechanism.

5. 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.

6. 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.

7. The fiber optic connector of claim 1 , wherein the housing defines:
a forward plug region that receives the ferrule;
a tail region; and
an intermediate region between the plug region and the tail region, the pivot joint projecting from the intermediate region.

8. The fiber optic connector of claim 1 , wherein the fingers extend to the front end of the housing.

9. The fiber optic connector of claim 1 , wherein the fingers are not connected to each other forward of the release bar.

10. The fiber optic connector of claim 1 , wherein the fingers are angled toward the central axis as they extend forwardly.

11. The fiber optic connector of claim 1 , wherein the housing conforms to all TIA FOCIS 3 SC connector requirements.

12. The fiber optic connector of claim 1 , wherein the housing is a unitary housing.

13. The fiber optic connector of claim 1 , wherein the catch protrudes away from the main body perpendicularly to the central axis.
