Abstract

An optical fiber connector assembly comprises at least one connector having a latching arm for coupling to an adapter, and a remote release tab having a protrusion configured to cooperate with the adapter to depress said latching arm when the remote release tab is pulled relative to the adapter. The optical fiber connector assembly may further be configured to have a deformable region at one end of the pull tab operatively connector to the latch arm assembly for releasing the connector from the adapter.

Claims

1. An optical fiber connector comprising:

a housing, body and coupling portion;

a latch located on a surface of the housing, wherein the latch has at least one latch cutout position on a surface of the latch configured to engage a corresponding adapter opening for securing the connector within the adapter; and

a remote release tab extending lengthwise from a first end portion adjacent to the housing to a free second end portion, the remote release tab comprising a deformable region between the first and second end portions, the deformable region being connected to the latch, the deformable region being configured to deform when the second end portion is pulled away from the first end portion such that the deformation of the deformable region deflects the latch for releasing the at least one latch cutout position from the corresponding adapter opening.

2. The optical fiber connector of claim 1, wherein a push force is exerted on the connector upon insertion of said connector into an adapter, the latch cutout engages an adapter opening to secure the connector within the adapter.

3. The optical fiber connector as set forth in claim 1, wherein the deformable region comprises a first segment and a second segment located between the first segment and the second end portion of the remote release tab, the first and second segments being connected to one another by a joint.

4. The optical fiber connector as set forth in claim 3, wherein the first segment rotates about the joint when the second end portion is pulled away from the first end portion.

5. The optical fiber connector as set forth in claim 4, wherein the first segment and the second segment have an included angle therebetween that decreases when the first segment rotates about the joint.

6. The optical fiber connector as set forth in claim 5, wherein the included angle is greater than 180°

when the remote release tab is positioned so that the latch cutout position can engage the corresponding adapter opening and the included angle is less than or equal to 180°

when the second end portion of the remote release tab is pulled away from the first end portion such that the deformable region deflects the latch for releasing the latch from the adapter.

7. The optical fiber connector as set forth in claim 1, wherein the first end portion of the remote release tab extends transverse to a lengthwise axis of the connector.

8. The optical fiber connector as set forth in claim 7, wherein at least one segment of the deformable region extends transverse to the first end portion.

9. The optical fiber connector as set forth in claim 1, wherein the first end portion of the remote release tab is anchored on the housing.

11. The optical fiber connector as set forth in claim 3, wherein the deformable region comprises a first segment and a second segment located between the first segment and the second end portion of the remote release tab, the first and second segments being connected to one another by a joint.

12. The optical fiber connector as set forth in claim 11, wherein the first segment rotates about the joint when the second end portion is pulled away from the first end portion.

13. The optical fiber connector as set forth in claim 12, wherein the first segment and the second segment have an included angle therebetween that decreases when the first segment rotates about the joint.

14. The optical fiber connector as set forth in claim 13, wherein the included angle is greater than 180°

when the remote release tab is positioned so that the latch can engage the adapter and the included angle is less than or equal to 180°

when the second end portion of the remote release tab is pulled away from the first end portion such that the deformable region deflects the latch for releasing the latch from the adapter.

15. The optical fiber connector as set forth in claim 3, wherein the first end portion of the remote release tab extends transverse to a lengthwise axis of the connector.

16. The optical fiber connector as set forth in claim 15, wherein at least one segment of the deformable region extends transverse to the first end portion.

17. The optical fiber connector as set forth in claim 3, wherein the first end portion of the remote release tab is anchored on the housing.

10. An optical fiber connector comprising:

a housing, body and coupling portion; and

a latch located on a surface of the housing wherein the latch is configured to engage a corresponding adapter for securing the connector within the adapter, and

a remote release tab extending lengthwise from a first end portion adjacent to the housing to a free second end portion, the remote release tab comprising a deformable region between the first and second end portions, the deformable region being connected to the latch, the deformable region being configured to deform when the second end portion is pulled away from the first end portion such that the deformation of the deformable region deflects the latch for releasing the latch from the adapter.
