Detector capable of preventing overpressure

The detection device capable of preventing overpressure is used for detecting the container of one conducting module to circuit board. The detection device includes the first testing board, at least one conducting pin, the second testing board, at least one elastic element and the third testing board. The first testing board has one first surface, one second surface and one through hole penetrating the first surface and the second surface; the conducting pin is set on the first surface and penetrates the second testing board set on the first surface; and the elastic element has one end set on the second testing board and the other end set on the third testing board set inside the through hole.
