An embodiment of the present invention discloses a PCB board plug mechanism configured to implement hot plug of a PCB board, and including an output end that moves along a second direction when the input end moves. The second direction is at an angle with the first direction. The connector for connecting the to-be-plugged PCB board is disposed at the output end. In a process in which the output end moves along the second direction, the PCB board can be driven to perform a corresponding hot plug action.

The present invention relates to a heat dissipation system. The heat dissipation system includes: a chassis, configured to house single boards of an orthogonal architecture, where the single boards includes a vertically inserted board; a first fan group, installed inside a first air intake pipe in the upper front of the chassis and configured to guide air into the chassis; and an air guide cavity, installed inside the chassis and configured to transfer the air that is guided by the first fan group into the chassis to a component on the vertically inserted board to perform heat dissipation. With the heat dissipation system in embodiments of the present invention, air is separately supplied to a heat dissipation component on a vertically inserted board in a communications system device based on an orthogonal architecture.

Heat dissipation system

The present invention discloses a circuit board interconnection architecture, which includes at least one first plugboard and at least two second plugboards substantially perpendicular to the first plugboard, where at least one of the first plugboard and the second plugboards is provided with several slots; the first plugboard and the second plugboards are mated and electrically connected by using signal connectors on both sides of the slots. The circuit board interconnection architecture solves a fitting precision problem of the first plugboard and the second plugboards in orthogonal directions. Even though there is an assembly tolerance between the first plugboard and the second plugboards, the connectors still satisfy assembly precision requirements, which can also avoid overall deformation of a first circuit board and a second circuit board after the first plugboard and the second plugboards are interconnected and mated orthogonally.
