ABSTRACT:
The present invention is to provide a thin type vacuum chamber device, wherein two hollow slabs are fastened by a claw fastener to form a thin type simple structure that can maintain a high vacuum state, and wherein the air inside the chamber is pumped out to attain a vacuum state with a high pressure suction activity. The thin-chamber design of the present invention can decrease the number of the components and reduce the cost. The special assembly design of the vacuum chamber of the present invention can effectively decrease the length of the transmission cable and thus can reduce signal attenuation and noise interference. The present invention has the advantage of convenient operation and is very suitable to a two-dimensional infrared sensor.
