Abstract

A fiber optic connector assembly is mated with a bracket on a printed circuit board at one end and inserted into a backplane adapter that is adjacent a backplane. In particular a spring push in slidingly attached to the bracket and also to the housing of the fiber optic connector assembly. The housing of the fiber optic connector assembly insertable into the backplane adapter using passive alignment features. A fiber optic ferrule in the fiber optic connector assembly is biased in a forward direction by a spring in the spring push. At the same time the spring allows for movement of the spring push within the housing to allow for movement of the printed circuit board relative to the backplane adapter.

First claim

We claim:

1. A backplane adapter for a pair of fiber optic connectors, each of the pair of fiber optic connectors having a fiber optic connector housing, the backplane adapter comprising:
a main body with an outer stop surface configured to engage a stop portion of a fiber optic connector housing, the main body being rectangular and having a top and a bottom separated by two opposite side walls to define an opening in the main body for accepting the pair of fiber optic connectors; and
an alignment passageway within the main body of the backplane adapter to receive an alignment feature on the fiber optic connector housing, the alignment passageway having a length that is longer than a length of the alignment feature, the stop portion of the fiber optic connector housing engaging the outer stop surface before a front end of the alignment feature engages an internal portion of the backplane adapter,
wherein the alignment passageway has a different width on the top than on the bottom inside the opening.

2. The backplane adapter according to claim 1 , further comprising at least one alignment step passageway to receive at least one alignment step on the fiber optic connector housing.

3. The backplane adapter according to claim 1 , wherein the alignment passageway is present adjacent a top and/or a bottom of the main body and within an opening of the main body.

4. The backplane adapter according to claim 1 , wherein the backplane adapter is free of any latching mechanism to receive the fiber optic connector housing.

5. A backplane having the backplane adapter according to claim 1 along with an at least one additional backplane adapter.

6. The backplane adapter according to claim 1 , wherein at least one of the pair of fiber optic connectors is an MXC® brand fiber optic connector.

7. A backplane for mating a plurality of fiber optic connectors, the backplane comprising:
a first side facing a printed circuit board and adjacent thereto;
a second side opposite the first side; and
at least one cutout to receive at least one backplane adapter thereat,
wherein the at least one backplane adapter has a main body, the main body being rectangular and having a top and a bottom separated by two opposite side walls to define an opening in the main body for accepting the pair of fiber optic connectors and positioned such that a portion of the main body is on the first side and another portion of the main body is on the second side, the portion of the main body facing the printed circuit board further comprising:
an outer stop surface configured to engage a stop portion on a fiber optic connector housing of a fiber optic connector operably coupled to the printed circuit board,
an alignment passageway within the main body of the backplane adapter to receive an alignment feature on the fiber optic connector housing, the alignment passageway having a length that is longer than a length of the alignment feature and the alignment passageway has a different width on the top than on the bottom inside the opening, and
wherein the stop portion of the fiber optic connector housing engaging the outer stop surface before a front end of the alignment feature engages an internal portion of the backplane adapter.

8. The backplane according to claim 7 , wherein the at least one backplane adapter further comprises:
at least one step alignment step passageway to receive at least one alignment step on the fiber optic connector housing.

9. The backplane according to claim 7 , wherein the alignment passageway is present adjacent a top and/or a bottom of the main body and within an opening of the main body of the at least one backplane adapter.

10. The backplane according to claim 7 , wherein the at least one backplane adapter is free of any latching mechanism to receive the fiber optic connector housing.

11. The backplane according to claim 7 , wherein the at least one backplane adapter further comprises:
an alignment arm stop in an opening in the at least one backplane adapter, the at least one outer connector stop facing a direction opposite that of the stop surface of the fiber optic connector.

12. A backplane adapter for a pair of fiber optic connectors, each of the pair of fiber optic connectors having a fiber optic connector housing, the backplane adapter comprising:
a main body with an outer stop surface configured to engage a stop portion of a fiber optic connector housing from a printed circuit board side of a backplane holding the backplane adapter; and
an alignment passageway within the main body of the backplane adapter to receive an alignment feature on the fiber optic connector housing, the alignment passageway having a length that is longer than a length of the alignment feature, the stop portion of the fiber optic connector housing engaging the outer stop surface before a front end of the alignment feature engages an internal portion of the backplane adapter,
wherein the alignment passageway has a different width on a top than on a bottom inside an opening in the main body for accepting the pair of fiber optic connectors.

13. A backplane having the backplane adapter according to claim 12 along with an at least one additional backplane adapter.

14. The backplane adapter according to claim 12 , wherein at least one of the pair of fiber optic connectors is an MXCC® brand fiber optic connector.

15. The backplane adapter according to claim 12 , wherein the at least one backplane adapter further comprises:
at least one step alignment step passageway to receive at least one alignment step on the fiber optic connector housing.

16. The backplane adapter according to claim 12 , wherein the alignment passageway is present adjacent a top and/or a bottom of the main body and within the opening of the main body of the at least one backplane adapter.
