Protection frame for CPCI architecture satellite communication hardware platform daughter board

The invention discloses a protection frame for a CPCI architecture satellite communication hardware platform daughter board, and the protection frame comprises a frame main body which is shaped like adustpan and is used for fixing the daughter board. The frame main body is provided with a U-shaped frame for accommodating the daughter board, and the installation surface of the frame main body is also provided with an installation column which enables the back of the daughter board and the surface of the installation surface to be separated by a small distance, thereby facilitating the heat dissipation. In addition, the frame is also provided with an opening which is used for the passing of a lateral interface of the daughter board, which facilitates the plugging of the interface when the daughter board is in use. Therefore, the frame can greatly improve the structural strength of the daughter board, and protects the daughter board from being inclined and loosened in a use and transportation process. 本发明公开了种CPC
