The invention discloses a ground signal input device for a space electric field detecting sensor. A shell sleeves the outer side of the space electric field detecting sensor. Conductive rubber is fixedly arranged in the shell, and the conductive rubber and the space electric field detecting sensor are lapped. A signal line is also comprised. One end of the signal line is connected to the conductive rubber through a conductive piece, and the other end is led to the outside of the shell through a hole arranged on the shell. The invention discloses the ground signal input device for the space electric field detecting sensor, the structural design is scientific and reasonable, the ground signal input at the space electric field detecting sensor can be realized, and the surface state of the sensor is not destroyed. At the same time, the shielding effect to a space interference signal in a sensor ground test can be realized, and the testing precision is improved.
Description
technical field [0001] The invention relates to the technical field of space environment detection, in particular to a ground signal input device for a space electric field detection sensor. Background technique [0002] The space electric field detection sensor uses the method that the surface of the sensor senses the potential of the space plasma environment where it is located to achieve the purpose of electric field measurement. When testing the performance of the sensor on the ground, it is necessary to apply a standard signal on the surface of the sensor. The surface of the sensor is a sensitive part, so the use of metal hard contact will affect the state of the sensor surface and cause weak damage to the surface. It is necessary to use a soft conductive material to contact the surface of the sensor; and because the sensor The surface is exposed to the air, and the space interference signal should be shielded to improve the test accuracy. [0003] In the document "ICE...
