Abstract

Embodiments of the present invention disclose a plug-in mechanism, a subrack including the plug-in mechanism, and a finished board, and relate to a power mechanism, so as to implement fast and reliable plug-in and plug-out by using a lever assistance effect, and a gearing effect of a parallelogram mechanism. The plug-in mechanism provided by an embodiment of the present invention is configured to be disposed between a sub-carrier frame and a parent carrier frame to implement plug-in and plug-out of the sub-carrier frame in the parent carrier frame, and the plug-in mechanism includes a driving part and a gearing part.

First claim

What is claimed is:

1. A plug-in mechanism configured to be disposed between a sub-carrier frame and a parent carrier frame to implement plug-in and plug-out of the sub-carrier frame relative to the parent carrier frame, the plug-in mechanism comprising:
an ejector lever; and
a gearing part comprising at least two parallel rotating connecting rods, wherein one end of each of the rotating connecting rods is fastened to the sub-carrier frame by a rotating shaft, two of the rotating connecting rods are adjacent and are connected at the other end by a translational connecting rod, at least one of the rotating connecting rods is connected to the ejector lever, and each of the rotating connecting rods is configured to removably connect to the parent carrier frame by a corresponding linkage structure, each linkage structure comprising a first groove that is open at one end and a linkage stud that is configured to slide into the open end of the first groove.

2. The plug-in mechanism according to claim 1 , wherein the linkage stud is disposed on the corresponding rotating connecting rod, and the first groove is provided on the parent carrier frame.

3. The plug-in mechanism according to claim 1 , further comprising a guide structure comprising a guide groove and a guide stud that is configured to slide into the guide groove, wherein an extension direction of the guide groove is perpendicular to an extension direction of the first groove.

4. The plug-in mechanism according to claim 3 , wherein:
the guide groove is provided on the parent carrier frame, and the guide stud is disposed on the sub-carrier frame; or
the guide groove is provided on the sub-carrier frame, and the guide stud is disposed on the parent carrier frame.

5. The plug-in mechanism according to claim 1 , further comprising a position-limit part disposed on the sub-carrier frame and configured to lock a position of the ejector lever after the sub-carrier frame is plugged in position.

6. A subrack, comprising:
a sub-carrier frame and a parent carrier frame; and
a plug-in mechanism disposed on two opposite sides of the sub-carrier frame and two corresponding sides of the parent carrier frame, the plug-in mechanism comprising:
an ejector lever, and
a gearing part comprising at least two parallel rotating connecting rods, wherein one end of each of the rotating connecting rods is fastened to the sub-carrier frame by a rotating shaft, two of the rotating connecting rods are adjacent and are connected at the other end by a translational connecting rod, at least one of the rotating connecting rods is connected to the ejector lever, and each of the rotating connecting rods is configured to removably connect to the parent carrier frame by a corresponding linkage structure, each linkage structure comprising a first groove that is open at one end and a linkage stud that is configured to slide into the open end of the first groove.

7. The subrack according to claim 6 , wherein the linkage stud is disposed on the corresponding rotating connecting rod, and the first groove is provided on the parent carrier frame.

8. The subrack according to claim 6 , further comprising a guide structure comprising a guide groove and a guide stud that is configured to slide into the guide groove, wherein an extension direction of the guide groove is perpendicular to an extension direction of the first groove.

9. The subrack according to claim 8 , wherein:
the guide groove is provided on the parent carrier frame, and the guide stud is disposed on the sub-carrier frame; or
the guide groove is provided on the sub-carrier frame, and the guide stud is disposed on the parent carrier frame.

10. The subrack according to claim 6 , further comprising a position-limit part disposed on the sub-carrier frame and configured to lock a position of the ejector lever after the sub-carrier frame is plugged in position.

11. The subrack according to claim 6 , wherein ejector levers of plug-in mechanisms on the two sides are connected by a connecting rod, so as to implement linkage between the plug-in mechanisms on the two sides.

12. A finished board, comprising:
a daughter board and a mainboard; and
a subrack comprising a sub-carrier frame and a parent carrier frame, wherein a plug-in mechanism is disposed on two opposite sides of the sub-carrier frame and two corresponding sides of the parent carrier frame, the plug-in mechanism comprising:
an ejector lever, and
a gearing part comprising at least two parallel rotating connecting rods, wherein one end of each of the rotating connecting rods is fastened to the sub-carrier frame by a rotating shaft, two of the rotating connecting rods are adjacent and are connected at the other end by a translational connecting rod, at least one of the rotating connecting rods is connected to the ejector lever, and each of the rotating connecting rods is configured to removably connect to the parent carrier frame by a corresponding linkage structure, each linkage structure comprising a first groove that is open at one end and a linkage stud that is configured to slide into the open end of the first groove;

wherein the daughter board and the mainboard are disposed in the sub-carrier frame and the parent carrier frame respectively, and plug-in and plug-out of the sub-carrier frame relative to the parent carrier frame implement connection and detachment between the daughter board and the mainboard.

13. The finished board according to claim 12 , wherein the linkage stud is disposed on the corresponding rotating connecting rod, and the first groove is provided on the parent carrier frame.

14. The finished board according to claim 12 , further comprising a guide structure comprising a guide groove and a guide stud that is configured to slide into the guide groove, wherein an extension direction of the guide groove is perpendicular to an extension direction of the first groove.

15. The finished board according to claim 14 , wherein:
the guide groove is provided on the parent carrier frame, and the guide stud is disposed on the sub-carrier frame; or
the guide groove is provided on the sub-carrier frame, and the guide stud is disposed on the parent carrier frame.

16. The finished board according to claim 12 , further comprising a position-limit part disposed on the sub-carrier frame and configured to lock a position of the ejector lever after the sub-carrier frame is plugged in position.

17. The finished board according to claim 12 , wherein a connector is disposed on the daughter board and the mainboard, and a free end of the connector disposed on the daughter board can be plug-connected to a free end of the connector disposed on the mainboard.
