Abstract

Embodiments disclosed herein include fiber optic connectors that include a tray that translates from a retracted position to an extended position along with cable assemblies using the connector and methods for making the same. In one embodiment, the connector includes a housing, a fiber optic body having an optical interface with at least one optical channel, at least one optical fiber in optical communication with the at least one optical channel of the optical interface, a tray that is movable between a first position that retracts the tray into the housing and a second position where the tray extends from the housing, wherein the fiber optic body is essentially stationary with respect to the tray, and an actuator for moving the tray between the first position and the second position.

First claim

We claim:

1. A fiber optic connector, comprising:
a housing;
a fiber optic body having an optical interface with at least one optical channel;
at least one optical fiber in optical communication with the at least one optical channel of the optical interface, the at least one optical fiber being attached to the fiber optic body;
a tray that is movable between a first position that retracts the tray into the housing and a second position where the tray extends from the housing, wherein the fiber optic body is fixed at a position inside the housing independent of the tray being located at the first position or the second position;
at least one alignment member that translates with the tray when moved from the second position to the first position;
at least one rail attached to the tray; and
an actuator for moving the tray between the first position and the second position.

2. The fiber optic connector of claim 1 , wherein the optical interface is accessible at a front end of the housing when the tray is in the first position.

3. The fiber optic connector of claim 1 , further including one or more electrical conductors.

4. The fiber optic connector of claim 3 , wherein the electrical conductors include a stationary portion and a movable portion.

5. The fiber optic connector of claim 4 , wherein the movable portion of the electrical conductors move with the tray between the first position and the second position and the optical interface does not move with the tray.

6. The fiber optic connector of claim 1 , wherein the tray has an open side at an engagement end.

7. The fiber optic connector of claim 1 , wherein the tray has one or more windows for receiving the actuator and allowing movement of the actuator.

8. The fiber optic connector of claim 1 , further including a second actuator on opposite sides of the housing.

9. The fiber optic connector of claim 1 , wherein the optical interface includes an integrated lens, a discrete lens or the at least one optical fiber.

10. The fiber optic connector of claim 1 , wherein the at least one alignment member includes one or more alignment pins being attached to the tray.

11. The fiber optic connector of claim 1 , wherein one or more components of the fiber optic connector provide coarse alignment for the optical interface before one or more guide pins engage.

12. The fiber optic connector of claim 1 , wherein the fiber optic connector is a portion of a cable assembly.

13. A fiber optic connector, comprising:
a housing;
a fiber optic body having an optical interface with at least one optical channel;
at least one optical fiber in optical communication with the at least one optical channel of the optical interface, the at least one optical fiber being attached to the fiber optic body;
a tray that is movable between a first position that retracts the tray into the housing and a second position where the tray extends from the housing, wherein the fiber optic body is fixed at a position inside the housing independent of the tray being located at the first position or the second position, wherein the optical interface is accessible at a front end of the housing when the tray is in the first position;
one or more electrical conductors, wherein the electrical conductors include a stationary portion and a movable portion, and the movable portion of the electrical conductors move with the tray between the first position and the second position and the optical interface and the stationary portion of the electrical conductors do not move with the tray;
at least one alignment member that translates with the tray when moved from the second position to the first position;
at least one rail attached to the tray; and
an actuator for moving the tray between the first position and the second position.

14. The fiber optic connector of claim 13 , wherein the tray has an open side at an engagement end.

15. The fiber optic connector of claim 13 , wherein the tray has one or more windows for receiving the actuator and allowing movement of the actuator.

16. The fiber optic connector of claim 13 , further including a second actuator on opposite sides of the housing.

17. The fiber optic connector of claim 13 , wherein the optical interface includes an integrated lens, a discrete lens or the at least one optical fiber.

18. The fiber optic connector of claim 13 , wherein the at least one alignment member includes one or more alignment pins being attached to the tray.

19. The fiber optic connector of claim 13 , wherein one or more components of the fiber optic connector provide coarse alignment for the optical interface before one or more guide pins engage.

20. The fiber optic connector of claim 13 , wherein the fiber optic connector is a portion of a cable assembly.
