Plug-in mechanism, subrack including plug-in mechanism, and finished board

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, and the plug-in mechanism comprising, a driving part comprising an ejector lever, and
• a gearing part comprising at least two mutually-parallel rotating connecting rods, one end of each of the rotating connecting rods is fastened onto the sub-carrier frame by using a rotating shaft, two of the rotating connecting rods that are adjacent are connected at the other end by using a translational connecting rod, the rotating connecting rod located on one side is connected to the ejector lever, and at least one of the rotating connecting rods is connected to the parent carrier frame by using a linkage structure.

A finished board, comprising:

• a daughter board and a mainboard;
• 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, and the plug-in mechanism comprises:
• a driving parting an ejector lever, and
• a gearing part comprising at least two mutually-parallel rotating connecting rods, one end of each of the rotating connecting rods is fastened onto the sub-carrier frame by using a rotating shaft, two of the rotating connecting rods that are adjacent are connected at the other end by using a translational connecting rod, the rotating connecting rod located on one side is connected to the ejector lever, and at least one of the rotating connecting rods is connected to the parent carrier frame by using a linkage structure;
• and
• wherein the daughter board and the mainboard are disposed in a sub-carrier frame and a parent carrier frame respectively, and plug-in and plug-out of the sub-carrier frame in the parent carrier frame implement connection and detachment between the daughter board and the mainboard.
