Abstract

A new fiber optic connector provides a very small form factor with reduced size. The fiber optic connector may comprise a single-body housing having a front end and rear end in a longitudinal direction, two ferrules accommodated in the housing and protruding from the front end of the housing, a back housing positioned adjacent to the rear end of the housing, two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward, and a boot assembly connected to the rear end of the housing. The housing comprises a latch arm extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter.

Claims (16)

1. A fiber optic connector with reduced size, comprising:

a single-body housing having a front end and rear end in a longitudinal direction, and including a top wall and a bottom wall extending from the front end to the rear end;

two ferrules accommodated in the housing and protruding from the front end of the housing, and the two ferrules spaced from each other in a direction extending between the top wall and the bottom wall;

a back housing positioned adjacent to the rear end of the housing;

two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward; and

a boot assembly connected to the rear end of the housing,

wherein the fiber optic connector comprises a latch arm connecting to the top wall and extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter, and

wherein the back housing includes upper and lower wings projecting from the back housing.

2. The fiber optic connector of claim 1 , wherein each of the two ferrules includes an indentation.

3. The fiber optic connector of claim 1 , wherein each of the two ferrules has a diameter of about 1.25 mm.

4. The fiber optic connector of claim 1 , wherein the housing includes two openings adjacent to the front end, and two openings are configured to hold the two ferrules.

5. The fiber optic connector of claim 1 , wherein the back housing is configured to be received in the housing.

6. The fiber optic connector of claim 5 , wherein the upper and lower wings are configured to snap into the housing to prevent the withdrawal of the back housing from the housing.

7. The fiber optic connector of claim 1 , wherein the back housing includes upper and lower posts.

8. The fiber optic connector of claim 1 , wherein the latch arm includes a connection end to the housing and a free end spaced a distance from the housing, and an intermediate catch is provided between the connection end and free end.

9. The fiber optic connector of claim 8 , wherein the intermediate catch includes a ramp surface and a substantially vertical surface.
