Area array type combined infrared sensor

The invention discloses an area array type combined infrared sensor, and particularly relates to the field of sensors, the area array type combined infrared sensor comprises a protective shell, an insertion hole is formed in the center of the protective shell, a central positioning rod is inserted into the insertion hole, and one end, penetrating through the insertion hole, of the central positioning rod is fixedly connected with an area array type infrared sensing frame. According to the embodiment, the mounting column is inserted into the limiting curved rod along the interior of the limiting curved rod, the mounting head is firstly in a compressed state along the inner wall of the thermodetector temperature measuring frame through the auxiliary spring at the moment, when the mounting head moves to the auxiliary hole, the mounting head is recovered to the original position through the spring recovery of the auxiliary spring, and the mounting head is inserted into the auxiliary hole. The installation head ca
