Abstract

An optical connector holding two or more LC-type optical ferrules is provided. A plural of optical connectors are ganged together into when insert into an adapter. To remove the connectors together or individually a removal tool is attachable to one or more of the connectors. The removal tool has a plural of release arms that in first position can release the fiber optic connector from the adapter receptacle. Release aim in a second position prevents the fiber optic connector from being released from the adapter receptacle. The removal tool is moved distally to actuate or retain the fiber optic connectors within their corresponding adapter receptacle.

First claim

The invention claimed is:

1. A removal tool for simultaneously releasing a plurality of fiber optic connectors from an adapter receptacle, each fiber optic connector further comprises a push/pull tab, each push/pull tab having a proximal end portion and an opposite distal end portion configured to be spaced apart from the adapter receptacle by a greater distance than the proximal end portion when the fiber optic connectors are mated with the adapter receptacle, each push/pull tab having a recess at the distal end portion thereof, the removal tool comprising:
a housing having a proximal end portion and a distal end portion spaced apart along a first axis and a first side portion and a second side portion spaced apart along a second axis, the proximal end portion being spaced apart from the distal end portion in a distal-to-proximal direction along the first axis, the housing comprising one or more release arms, the one or more release arms comprising one or more release arm protrusions and the one or more release arms being deflectable relative to at least one of the proximal end portion and the distal end portion of the housing,
wherein the housing is configured to be loaded onto the distal end portions of the push/pull tabs of the plurality of fiber optic connectors by movement relative to the plurality of fiber optic connectors in the distal-to-proximal direction so that the one or more release arm protrusions are accepted in the recesses of the push/pull tabs of the plurality of fiber optic connectors at the same time for locking the removal tool with the plurality of fiber optic connectors,
wherein the plurality of fiber optic connectors are spaced apart along the second axis when the one or more release arm protrusions are accepted in the recesses of the push/pull tabs of the plurality of fiber optic connectors at the same time;
wherein when the one or more release arm protrusions are accepted in the recesses of the push/pull tabs of the plurality of fiber optic connectors at the same time, the removal tool can be selectively operated to:
release the plurality of fiber optic connectors from the adapter receptacle by displacing the removal tool distally; and
disconnect from the plurality of the fiber optic connectors upon deflecting the one or more release arms

wherein each of the one or more release arms has a distal end portion and a proximal end portion spaced apart along the first axis, wherein each release arm is cantilevered from the distal end portion of the housing such that the distal end portion of each release arm adjoins the distal end portion of the housing.

2. The removal tool assembly for releasing one or more fiber optic connectors from an adapter receptacle according to claim 1 , wherein the housing is formed from a single piece of material.

3. A combination comprising the removal tool of claim 1 and a plurality of fiber optic connectors, each fiber optic connector comprising a push/pull tab, each push/pull tab having a recess at a distal end thereof configured to accept the one or more release arm protrusions to operatively couple the removal tool to the plurality of fiber optic connectors.

4. The removal tool assembly for releasing one or more fiber optic connectors from an adapter receptacle according to claim 1 , wherein the housing comprises a wall and the one or more release arms comprises a plurality of release arms formed on the wall at a plurality of spaced apart locations along the second axis.

5. The removal tool assembly as set forth in claim 1 , wherein the proximal end portion of each release arm is spaced apart from the proximal end portion of the housing by a gap extending along the first axis.
