Description
technical field [0001] The invention belongs to the technical field of space remote sensing, and in particular relates to a double-cavity isolation electromagnetic shielding structure of an electric control box of a space remote sensor. Background technique [0002] In addition to the structural performance of the space remote sensor electric control box, it must have high specific rigidity to realize the load on the circuit board and electronic devices. Another important performance is to have high electromagnetic shielding performance to ensure that the electric control box is not affected. The interference of the external electromagnetic environment does not affect the external electronic equipment. For the electric control box of the space remote sensor, due to its non-repairability and high reliability requirements, the electromagnetic shielding performance of the electric control box is highly required. The circuit of the electric control box is complicated, and there...
