Abstract

An optical connector adapter for connecting optical connectors comprising a frame adapted to be mounted to a printed circuit board; and at least one adapter housing movably mounted in a receiving area of the frame. The optical connector adapter is independently floatable along a Z-axis relative to the frame. The adapter housing is sized and shaped to receive at least two optical connectors therein and individually fixedly connect the optical connectors to the adapter housing. The optical connectors are received in opposite directions into the adapter housing and connect to each other inside the adapter housing.

Claims

1. An optical connector adapter for connecting optical connectors, the adapter comprising:

a frame adapted to be mounted to a printed circuit board; and

at least one adapter housing movably mounted in a receiving area of the frame, the adapter housing including at least one spring on a surface of the adapter housing adapted to be received in a spring receiving area of the frame, wherein the spring is adapted to spring load the adapter housing on the frame; and

wherein the adapter housing is adapted to receive at least two optical connectors therein and individually fixedly connect the optical connectors to the adapter housing, and wherein the optical connectors are received in opposite directions into the adapter housing and connect to each other inside the adapter housing.

2. An adapter as in claim 1 wherein the adapter comprises a plurality of the adapter housings located in the receiving area and separately movable relative to each other.

3. An adapter as in claim 2 wherein the adapter housings are located adjacent each other.

4. An adapter as in claim 1 further comprising at least one spring between portions of the frame and the at least one housing for biasing the at least one housing in a first direction relative to the frame.

5. An adapter as in claim 4 wherein the adapter comprises two of the springs for each of the housings, the springs being located at opposite sides of each housing.

6. An adapter as in claim 4 wherein the at least one spring comprises a leaf spring.

7. An adapter as in claim 4 wherein the at least one spring comprises a coil spring.

8. An adapter as in claim 4 further comprising at least one retainer connected to the frame, the at least one retainer having a portion located in a path of a portion of the at least one adapter housing for limiting movement of the adapter housing in the first direction.

9. An adapter as in claim 8 wherein the adapter comprises two of the retainers located on opposite sides of the at least one adapter housing.

10. An adapter as in claim 9 wherein each retainer contacts more than one of the adapter housings.

11. The adapter as in claim 1 wherein the adapter housing further comprises at least one projection on an exterior surface of the adapter housing, the projection adapted to provide a supporting surface against which the spring is biased when the spring receiving area of the frame is pressed against the spring when the adapter housing is movably mounted in the receiving area.

12. The adapter as in claim 1 wherein each adapter housing is adapted to move relative to each other and relative to the frame.

13. An adapter as in claim 1 wherein a movement of the adapter housing is in a Z-axis float relative to the printed circuit board.

14. An adapter as in claim 1 wherein the at least one adapter housing is movably mounted longitudinally relative to the frame.

15. An adapter as in claim 1 wherein the spring is adapted to spring load the adapter housing on the frame in a Z-axis float.

16. An adapter as in claim 1 wherein the spring is adapted to spring load the adapted housing on the frame in a horizontal plane.

17. An optical connector adapter for connecting optical connectors, the adapter comprising:

a frame adapted to be mounted to a printed circuit board;

at least one adapter housing movably mounted in a receiving area of the frame;

at least one retainer connected to the frame for preventing the adapter housing from exiting the receiving area out of a first side of the frame; and

at least one spring between the frame and the adapter housing biasing the adapter housing in a first direction towards the first side, wherein the adapter housing is movable relative to the frame in a second opposite direction with resilient deflection of the spring.

18. An adapter as in claim 17 wherein the adapter comprises a plurality of the adapter housings located in the receiving area and separately movable relative to each other.

19. An adapter as in claim 18 wherein the adapter housings are located adjacent each other.

20. An adapter as in claim 17 wherein the adapter comprises two of the springs for each of the housings located at opposite sides of each housing.

21. An adapter as in claim 17 wherein the at least one spring comprises a leaf spring.

22. An adapter as in claim 17 wherein the at least one spring comprises a coil spring.

23. An adapter as in claim 17 wherein the adapter comprises two of the retainers located on opposite sides of the at least one adapter housing.

24. An adapter as in claim 23 wherein each retainer contacts more than one of the adapter housings.

25. A method of assembling an optical connector adapter for connecting optical connectors on a backplane member, the method comprising steps of:

inserting a plurality of adapter housings into at least one receiving area of an adapter frame, the frame being adapted to be mounted to the backplane member, and the adapter housings each being adapted to removably connect two of the optical connectors thereto in opposite directions;

locating springs between the adapter housings and the adapter frame, wherein the adapter housings are movably mounted to the adapter frame and biased by the springs in a first direction relative to the adapter frame; and

connecting at least one retainer to the adapter frame to prevent the adapter housings from exiting the receiving area in the first direction.

26. In an assembly comprising a gang adapter block and a plurality of fiber optic adapters connected to the gang adapter block, wherein the improvement comprises:

each of the plurality of fiber optic adapters being independently floatable along a Z-axis relative to the gang adapter block.
