Camera module with high reliability

The invention relates to a high-reliability camera module which comprises a shell, a lens assembly and a connecting assembly which are arranged on the shell and a PCB assembly arranged in an inner cavity of the shell, the PCB assembly is located below the lens assembly, and one end of the connecting assembly penetrates through the shell and is connected with the PCB assembly; an opening is formed in one side of the shell, a side cover plate is fixedly connected to the opening, and the opening is sealed by the side cover plate. According to the invention, the shell adopts a structure with a window on the side surface, so that the upper shell and the lower shell of the shell at a Z-direction stress position are integrated, and the mechanical reliability risk is reduced; moreover, the PCB assembly does not need to be fixed by a screw, and the risk of warping and deformation of the PCB due to the pretightening force of the screw can be effectively improved, so that the risk that the resolution of the camera modul
