Abstract
The invention relates to an accelerometer grounding structure. According to the accelerometer grounding structure, the areas of left and right boss gold-plated areas on a swing sheet are extended so as to be in conductive connection with front surface and back surface boss gold-plated areas through conduction gold-plated areas; the swing sheet is placed on the end surface of an excitation ring on a torquer; two windows on the swing sheet are respectively aligned with two through holes on the torquer; grounding binding posts are welded and fixed on the boss gold-plated areas on the swing sheet by leads; the back surface boss gold-plated area is in contact with the excitation ring on the torquer; and the other ends of the grounding binding posts are in ground signal connection with a hybrid integrated circuit. According to the accelerometer grounding structure of the invention, the operation difficulty of workers is reduced, and the production efficiency is improved.
Description
technical field [0001] The patent of the present invention relates to an electrical grounding structure of an accelerometer, especially a grounding structure suitable for a quartz flexible accelerometer head. Background technique [0002] The working principle of the quartz flexible accelerometer is: use the force feedback principle to obtain a current proportional to the input acceleration, and obtain the input acceleration information by sampling the current. The structural composition of the quartz flexible accelerometer includes two parts: a hybrid integrated circuit and a meter head. The hybrid integrated circuit is the electrical structure part, and the meter is the mechanical structure part. The design requires that the electric signal of the accelerometer electrical structure and the mechanical structure part need to share the ground. The mechanical structure mainly includes the torque device and the pendulum assembly structure. The torquer structure is an importa...
