| titleOfInvention | A waterproof construction for PCB board |
| abstract | The utility model discloses a waterproof structure for a PCB (printed circuit board), which comprises a frame body, wherein a plurality of threading pipes are arranged on the side wall of the frame body in a penetrating way, a circuit board is arranged inside the frame body, the bottom of the frame body is fixedly connected with a bottom plate through bolts, the top of the frame body is fixedly connected with a top plate through bolts, and the bottom plate and the top plate are both connected with the frame body in a sealing way; the utility model discloses in, through the framework, the bottom plate, the cooperation of roof, form a sealed chamber, thereby effectively prevent external moisture and dust and circuit board contact, in order to avoid the circuit board the condition of short circuit to appear, the conduction oil in the cavity can pass through the bottom plate simultaneously, the roof is with timely transmission to first fin and second fin of heat, carry out the heat exchange with the outside air by first fin and second fin, in order to play good heat dissipation cooling effect to the circuit board, avoid the circuit board to be in high temperature state for a long time, the normal work of circuit board has been guaranteed, avoid electronic component to burn out. |
