Latch assembly for an optoelectronic module

1. A module, comprising:

a housing; and

a latch assembly at least partially positioned within the housing and having first and second associated states, and the latch assembly comprising:

an actuation sleeve having a first position that corresponds with the first state, and a second position that corresponds with the second state; and

first and second latch arms operably disposed with respect to the actuation sleeve so that respective first and second cam arrangements are defined where the latch arms are configured to rotate responsive to linear motion of the actuation sleeve, the latch arms partially extending from the housing when the actuation sleeve is in the first position, and the latch arms being substantially retracted within the housing when the actuation sleeve is in the second position.

2. The module as recited in claim 1 , wherein the actuation sleeve is configured and arranged for substantially linear motion with respect to the housing.

3. The module as recited in claim 1 , wherein:

the actuation sleeve defines first and second guides; and

the first and second latch arms each define a follower engaged with a respective guide.

4. The module as recited in claim 1 , wherein the module substantially complies with the X2 MSA.

5. The module as recited in claim 1 , wherein the actuation sleeve defines a pair of openings, each of the openings being substantially aligned with a corresponding receptacle of the module.

6. The module as recited in claim 5 , wherein when:

the actuation sleeve is in a retracted position, the latch arms are in an extended position; and

the actuation sleeve is in an extended position, the latch arms are in a retracted position.

7. The module as recited in claim 1 , wherein the actuation sleeve and the latch arms each comprise a monolithic element.

8. An optoelectronic module, comprising:

a housing; and

a latch assembly at least partially positioned within the housing and having first and second associated states, and the latch assembly comprising:

an actuation sleeve that defines first and second guides, and the actuation sleeve having a first position that corresponds with the first state, and a second position that corresponds with the second state; and

first and second latch arms that are interchangeable with each other, each of which defines a follower operably disposed with regard to a respective guide defined by the actuation sleeve, the latch arms being configured to rotate with respect to the actuation sleeve such that when the actuation sleeve is in the first position, the latch arms at least partially extend from the housing, and when the actuation sleeve is in the second position, the latch arms are substantially retracted within the housing.

9. The optoelectronic module as recited in claim 8 , further comprising:

first and second OSAs; and

a printed circuit board to which the first and second OSAs are connected, the first and second OSAs and printed circuit board being at least partially disposed within the housing.

10. The optoelectronic module as recited in claim 8 , wherein the latch assembly further includes first and second springs, each of the springs serving to bias a corresponding latch arm toward an extended latch arm position, each of the springs further serving to allow the corresponding latch arm to rotate into a retracted latch arm position when the bias imposed by the springs is overcome.

11. The optoelectronic module as recited in claim 8 , wherein the guides defined by the actuation sleeve each have a guide surface with a generally triangular shape, each of the guide surfaces being at least partially bounded by a respective guide ridge.

12. The optoelectronic module as recited in claim 8 , wherein each of the latch arms is pivotably engaged with the housing.

13. The optoelectronic module as recited in claim 8 , wherein the housing defines a pair of latch arm cavities within which respective latch arms are positioned.

14. The optoelectronic module as recited in claim 13 , wherein a cover of the housing comprises a pair of retaining elements, a portion of each of the retaining elements being received in a respective latch arm cavity.

15. A module, comprising:

a housing; and

a latch assembly at least partially positioned within the housing, and the latch assembly comprising:

an actuation sleeve slidingly engaged with the housing;

first and second latch arms operably disposed with respect to the actuation sleeve such that extension of the actuation sleeve away from the housing corresponds with rotation of the latch arms to a position where the latch arms are substantially retracted within the housing; and

first and second springs that bias the first and second latch arms, respectively, toward the position where the latch arms partially extend from the housing.

16. The module as recited in claim 15 , wherein the module is substantially compliant with the X2 MSA.

17. The module as recited in claim 15 , wherein:

the actuation sleeve defines first and second guides; and

the first and second latch arms each include a follower operably disposed with regard to a respective guide.

18. The module as recited in claim 15 , wherein the actuation sleeve and the first and second latch arms collectively define a pair of cam arrangements.

19. The module as recited in claim 15 , wherein the actuation sleeve and each of the latch arms comprise monolithic components.

20. The module as recited in claim 15 , wherein a latch arm and a spring are disposed in each of a pair of latch arm cavities defined by the housing.
