摘要: The invention discloses a safety inspection detector and a goods safety inspection system. The safety inspection detector at least comprises a circuit board, a first housing, a second housing, a detection module and a connecting interface. The detection module and the connecting interface are mounted on the circuit board. The first housing is pressed and connected to a first surface of the circuit board, and the second housing is pressed and connected to a second surface of the circuit board. The first housing and the second housing can hermetically wrap the detection module and electronic devices on the circuit board, but bypass the connecting interface to realize leading-out and connection with related interconnected cables by utilizing the connecting interface. The housings can be used for sealing and protecting sensitive electronic devices in the detector, thus being moisture proof and preventing interference.

摘要: The present application relates to a dual energy detector and a radiation inspection system. The dual energy detector comprises: a detector module mount and a plurality of detector modules. The detector module includes a higher energy detector array and a lower energy detector array, which are juxtaposedly provided on said detector module mount to be independently irradiated. The present application may simplify the arrangement of the photodiodes and printed circuit boards to which the higher and lower energy detector arrays are connected, such that necessary thickness dimension of the detector module mount is reduced, thereby facilitating the installation and use of the dual energy detector of the present application. On the other hand, the radiation beam in the present application may be independently irradiated to the higher and lower energy detector arrays juxtaposed to each other, which reduces to certain extent the mutual restriction during selection of the higher and lower energy detector arrays.
