Abstract

A sleeve has a handle and extensions to engage a fiber optic connector for insertion into and removal from high density adapters. The sleeve may have multiple connectors installed in a single sleeve and it may be removable. The sleeve has first and second extensions to engage the inner and outer housings, respectively, to insert and remove the fiber optic connector from an adapter.

Claims

1. A sleeve to be attached to an outer portion of a fiber optic connector to assist in installing and removing the fiber optic connector from an adapter comprising:

a body having an interior surface and an exterior surface, the interior surface defining a central opening extending between a front end and a back end, the central opening configured to receive at least a portion of the fiber optic connector;

at least one first extension extending from the body;

at least one second extension extending from the interior surface into the central opening, the at least one second extension disposed between the at least one first extension and the back end; and

an extended portion extending from a portion of the body away from the front end and beyond the back end.

2. The sleeve according to claim 1, wherein the at least one first extension is configured to engage an outer housing on the fiber optic connector and the at least one second extension is configured to engage an inner housing on the fiber optic connector.

3. The sleeve according to claim 1, the at least one first extension has a flat surface facing the back end of the sleeve to engage a forward facing surface of an outer housing on the fiber optic connector.

4. The sleeve according to claim 1, the at least one second extension has a flat surface facing the front end of the sleeve to engage a backward facing surface of an inner housing on the fiber optic connector.

5. The sleeve according to claim 1, wherein the body has an opening extending between the front end and back end along one side thereof.

6. The sleeve according to claim 1, wherein the extended portion is a generally round handle extending from the back end of the body.

7. The sleeve according to claim 1, wherein the extended portion is an extension of one side of the body.

8. The sleeve according to claim 1, wherein the at least one second extension extending from the interior surface comprises a raised surface disposed on an end of cantilevered member in a side wall of the body.

9. The sleeve according to claim 1, wherein the at least one first extension comprise at least two first extensions.

10. The sleeve according to claim 1, wherein the at least one second extension comprises at least two second extensions.

11. The sleeve according to claim 1, wherein the sleeve is removably attached to the fiber optic connector.

12. The sleeve according to claim 1, wherein the at least one first extension comprises at least four first extensions.

13. The sleeve according to claim 12, wherein two of the four first extensions comprise two tabs extending into an opening extending between the front end and back end along one side thereof and the other two of the first four first extensions comprise two raised portions extending from the interior surface of the body into the central opening.

14. The sleeve according to claim 1, wherein the sleeve sides forward and backward relative to the fiber optic connector.

15. The sleeve according to claim 1, wherein the at least one first extension engages the outer housing of the fiber optic connector when the sleeve is pulled in a backward direction.

16. The sleeve according to claim 1, wherein the at least one second extension engages the inner housing of the fiber optic connector when the sleeve is pushed in a forward direction.

17. A combination of a sleeve and a fiber optic connector, the fiber optic connector having an inner housing and an outer housing that are movable relative to one another, the sleeve being attached to the fiber optic connector and comprising:

a body having an interior surface and an exterior surface, the interior surface defining a central opening extending between a front end and a back end to receive the fiber optic connector;

at least one first extension extending from the body to engage the outer housing;

at least one second extension extending from the interior surface into the central opening to engage the inner housing, the at least one second extension disposed between the at least one first extension and the back end; and

an extended portion extending from a portion of the body away from the front end and beyond the back end.

18. A sleeve to install and remove multiple fiber optic connectors from a high density application, the sleeve comprising:

a body having a front end and a back end and at least two central openings extending therebetween, each of the central openings configured to removably receive a fiber optic connector therein, each of the central openings having an internal surface;

at least one first extension extending from the internal surface of each central opening to engage the outer housing;

at least one second extension extending from the interior surface of each central opening to engage the inner housing, the at least one second extensions disposed between the at least one first extension and the back end; and

an extended portion extending from a portion of the body away from the front end and beyond the back end to be used in installing and removing the fiber optic connector from an adapter.
