Eight-channel high-reliability CTP light source module

The utility model provides an eight-channel high-reliability CTP light source module. The eight-channel high-reliability CTP light source module comprises an eight-channel card inserting circuit board, eight laser devices, eight optical fibers, a heat dissipation aluminum sheet, eight optical fiber adapters, a cooling fin, a plastic strip, an upper plate and a passing opening plate. The cooling fin is fixedly connected with the corresponding position of the eight-channel card inserting circuit board, the heat dissipation aluminum sheet is aligned to the eight-channel card inserting circuit board and then screwed down through screws, and the cooling fin and the eight laser devices are fixed; the eight laser devices correspond to one ends of the eight optical fibers one to one, the other ends of the optical fibers are tightly pressed into slits of the optical fiber adapters, the optical fiber adapters are installed on the passing opening plate, the passing opening plate and the cooling fin are fixed, the plastic strip is placed between the cooling fin and the upper plate, and a light source module shell is formed by the upper plate and the passing opening plate. The eight-channel high-reliability CTP light source module has the advantages of being good in heat dissipating effect, high in working efficiency, low in cost and high in reliability.
