Abstract

Described herein is a system that includes a sled and a data storage device positioned within the sled. The sled includes a base, an electrical connector positioned within and movable relative to the base, and a locking mechanism. The locking mechanism is positioned within the base and movable, relative to the base and the electrical connector, between a locked position and a unlocked position. In the locked position, the locking mechanism restricts movement of the electrical connector in at least one degree of freedom relative to the base. In the unlocked position, the locking mechanism does not restrict movement of the electrical connector in the at least one degree of freedom relative to the base. The data storage device is co-movably coupled to the electrical connector.

First claim

What is claimed is:

1. A system, comprising:
a sled comprising:
a base,
an electrical connector positioned within and movable relative to the base; and
a locking mechanism positioned within the base and movable, relative to the base and the electrical connector, between a locked position and an unlocked position, wherein in the locked position the locking mechanism restricts movement of the electrical connector in at least one degree of freedom relative to the base, and in the unlocked position the locking mechanism does not restrict movement of the electrical connector in the at least one degree of freedom relative to the base; and

a data storage device positioned within the base and co-movably coupled to the electrical connector.

2. The system according to claim 1 , further comprising a cover configured to open and close, wherein the locking mechanism moves relative to the base between the locked position when the cover is open and the unlocked position when the cover is closed.

3. The system according to claim 1 , wherein the electrical connector comprises one of a printed circuit board, a flex printed circuit board, or a cable.

4. The system according to claim 1 , wherein the sled further comprises a biasing element configured to bias the locking mechanism into the locked position.

5. The system according to claim 4 , wherein the biasing element comprises a spring coupled to the locking mechanism at a first end of the spring and coupled to the base at a second end of the spring.

6. The system according to claim 1 , wherein:
the locking mechanism comprises a locking feature; and
the locking feature restricts movement of a tab of the electrical connector in at least one degree of freedom when the locking mechanism is in the locked position and wherein the locking feature does not restrict movement of the tab of the electrical connector in the at least one degree of freedom when the locking mechanism is in the unlocked position.

7. The system according to claim 1 , further comprising an enclosure, configured to store the sled and comprising an engagement element, wherein as the sled is positioned in the enclosure, the engagement element of the enclosure extends through the base and engages the locking mechanism to move the locking mechanism into the unlocked position.

8. The system according to claim 1 , wherein:
the sled further comprises an anchor configured to moveably retain the locking mechanism to the base; and
the locking mechanism further comprises an elongated slot and wherein the anchor and elongated slot are configured to restrict movement of the locking mechanism to a single direction.

9. The system according to claim 1 , wherein the electrical connector is fixed to a printed circuit board.

10. The system according to claim 1 , wherein the electrical connector comprises a printed circuit board, and wherein the printed circuit board is resiliently flexible to allow movement of the printed circuit board relative to the base.

11. The system according to claim 1 , wherein:
the electrical connector comprises a printed circuit board comprising a plurality of connector engagement features;
a connector engagement feature of the plurality of connector engagement features comprises a tab;
the sled further comprises a plurality of locking mechanisms; and
a locking mechanism of the plurality of locking mechanisms is configured to engage the tab of the connector engagement feature of the plurality of connector engagement features.

12. A sled comprising:
a base;
an electrical connector positioned within and movable relative to the base; and
a locking mechanism positioned within the base and movable, relative to the base and the electrical connector, between a locked position and a unlocked position, wherein in the locked position the locking mechanism restricts movement of the electrical connector in at least one degree of freedom relative to the base, and in the unlocked position the locking mechanism does not restrict movement of the electrical connector in the at least one degree of freedom relative to the base.

13. The sled according to claim 12 , further comprising a cover configured to open and close, wherein the locking mechanism moves relative to the base between the locked position when the cover is open and the unlocked position when the cover is closed.

14. The sled according to claim 12 , wherein the electrical connector comprises a printed circuit board, and wherein the printed circuit board is resiliently flexible to allow movement of the printed circuit board relative to the base.

15. The sled according to claim 12 , further comprising a biasing element configured to bias the locking mechanism into the locked position.

16. The sled according to claim 15 , wherein the biasing element comprises a spring coupled to the locking mechanism at a first end of the spring and coupled to the base at a second end of the spring.

17. The sled according to claim 12 , wherein the electrical connector is fixed to a printed circuit board.

18. The sled according to claim 12 , further comprising a cover configured to open and close, wherein the locking mechanism comprises a push tab, and wherein the sled further comprises a mechanical coupling between the cover and the push tab, the mechanical coupling configured to move the locking mechanism to the unlocked position when the cover is closed.

19. The sled according to claim 12 , wherein the locking mechanism comprises a hook, wherein the hook restricts movement of a tab of the electrical connector in at least one degree of freedom when the locking mechanism is in the locked position and wherein the hook does not restrict movement of the tab of the electrical connector in the at least one degree of freedom when the locking mechanism is in the unlocked position.

20. A method of constraining an electrical connector in at least one degree of freedom, the method comprising:
providing a sled comprising:
a base;
an electrical connector positioned within and movable relative to the base; and
a locking mechanism positioned within the base and movable,

relative to the base and the electrical connector, between a locked position and an unlocked position;
moving the locking mechanism to the locked position to restrict movement of the electrical connector in at least one degree of freedom relative to the base; and
moving the locking mechanism to the unlocked position to not restrict movement of the electrical connector in the at least one degree of freedom relative to the base.
