Set top box with protection mechanism

Abstract

The utility model relates to the technical field of set top boxes, in particular to a set top box with a protection mechanism, which comprises a protection shell, a protection cavity with an opening at one end is arranged in the protection shell, a PCB (printed circuit board) frame plate for mounting components is arranged in the protection cavity, and the protection mechanism is arranged outside the PCB frame plate. The protection mechanism comprises a plurality of buffer sleeves which are arranged outside the PCB frame plate and attached to the side wall of the protection cavity, and the opening of the protection cavity is provided with an installation assembly used for installing the PCB frame plate in the protection cavity. According to the set top box provided by the utility model, through the arrangement of the plurality of buffer sleeves covering the PCB frame plate, when the PCB frame plate vibrates in the protection cavity due to the fact that the protection shell falls off due to unexpected situations, the buffer sleeves can absorb part of vibration, so that the PCB frame plate is buffered, and the damage of components mounted on the PCB frame plate caused by vibration is reduced, and compared with an existing set top box, the set top box provided by the utility model has the advantages that the cost is reduced; according to the utility model, the protection mechanism can carry out buffer protection on components in the PCB frame plate, so that the damage of the components caused by falling is reduced.
