Abstract
A multi-fiber, fiber optic connector may include a reversible keying arrangement for determining the orientation for plugging the connector into an adapter to thereby allow for a change in polarity of the connection to be made on site. The connector housing may be configured to engage with a removable key that may be engaged with the housing in at least two different locations to provide the plug-in orientation, or the housing may have slidably displaceable keys movable between multiple positions on the housing.
Claims (24)
1. A fiber optic connector for mating with an adapter, the fiber optic connector comprising:
a connector housing having a longitudinal axis, the housing having a housing front end and a housing rear end spaced apart from the front end in a rear direction along the longitudinal axis, the housing comprising an exterior portion extending circumferentially about a space with respect to the longitudinal axis, the exterior portion including a top side wall and a bottom side wall, the connector housing being configured to receive a multi-fiber ferrule in the space between the top side wall and the bottom side wall, the top side wall comprising a groove along the longitudinal axis; and
a key configured to be received in a keyway of a mating adapter, the key having a top side and a bottom side;
a tongue disposed on the bottom side of the key, the tongue being configured to be received in the groove such that the key is externally positioned on the top wall; and
a retainer rearward of a location where the tongue is received in the groove, the retainer configured to engage the connector housing to retain the tongue and the key on the top side wall of the connector housing.
2. The fiber optic connector as set forth in claim 1 , wherein the groove has an open axial end.
3. The fiber optic connector as set forth in claim 2 , wherein the tongue is configured to be received in the groove by insertion along the longitudinal axis into the open axial end whereby the tongue slides in the groove.
4. The fiber optic connector as set forth in claim 3 , wherein the key has a key front end portion and a key rear end portion spaced apart along the longitudinal axis, the retainer being adjacent the key rear end portion.
5. The fiber optic connector as set forth in claim 3 , wherein the connector has a height extending from the bottom side wall to the top side wall and wherein the retainer is at a different level along the height than the tongue.
6. The fiber optic connector as set forth in claim 3 , where the retainer is releasable from the connector housing to allow for removal of the tongue and the key from the top side wall of the connector housing.
7. The fiber optic connector as set forth in claim 3 , wherein the connector housing comprises a protrusion on the top side wall, the retainer being configured to engage the protrusion.
8. The fiber optic connector as set forth in claim 3 , wherein the retainer is spaced apart from at least a portion of the tongue in the rear direction.
9. The fiber optic connector as set forth in claim 3 , wherein the key, the tongue, and the retainer are formed form a single piece of material.
10. The fiber optic connector as set forth in claim 3 , wherein the retainer comprises opposing lateral tabs defining a first width and the connector housing includes a pair of projections adjacent the groove, the pair of projections separated by an opening having a second width, the first width being greater than the second width.
11. The fiber optic connector as set forth claim 10 , wherein the fiber optic connector is configured so that as the tongue slides along the groove from the open axial end, the opposing lateral tabs pass through the opening in a first longitudinal direction.
12. The fiber optic connector as set forth claim 11 , wherein the fiber optic connector is further configured so that the opposing lateral tabs engage the pair of projections when the tongue is urged to slide in a second longitudinal direction opposite the first longitudinal direction in relation to the connector housing to resist withdrawal of the tongue from the groove, whereby the opposing lateral tabs and the pair of projections releasably retain the tongue and the key on the top side wall of the connector housing.
13. The fiber optic connector as set forth in claim 12 , wherein the tongue is dovetail-shaped.
14. The fiber optic connector as set forth in claim 13 , wherein the key is wider than the tongue.
15. The fiber optic connector as set forth in claim 13 , wherein the key and the tongue are formed from a single piece of material.
16. The fiber optic connector as set forth in claim 13 , wherein the top side wall has a top surface and the bottom side of the key slides against the top surface as the tongue slides in the groove.
17. The fiber optic connector as set forth in claim 1 , wherein the tongue is dovetail-shaped.
18. The fiber optic connector as set forth in claim 1 , wherein the key is wider than the tongue.
19. The fiber optic connector as set forth in claim 1 , wherein the key and the tongue are formed from a single piece of material.
20. The fiber optic connector as set forth in claim 1 , wherein the fiber optic connector is an MPO connector.
