The invention discloses a crystal oscillator vibration damping device based on flexible reeds. The first flexible reed and the second flexible reed are symmetrically arranged on the four sides of the crystal oscillator, and the adjusting screw and the adjusting nut are connected through a screw pair. All the other parts are connected by screws. The present invention realizes the damping function through the first flexible reed and the second flexible reed, and realizes the adjustment of the damping stiffness through the screw mechanism composed of the adjusting screw and the adjusting nut. The first flexible reed and the second flexible reed use high elasticity Made of impact-resistant spring steel, it can provide better vibration damping effect. In addition, the present invention has compact structure, rich configuration of flexible reeds, large design space, wide applicability, good vibration damping performance, easy adjustment of stiffness, high and low temperature resistance, corrosion resistance, not easy to aging, and has strong practicability and Broad application prospects.
Description
technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a crystal vibration damping device based on a flexible reed. Background technique [0002] Airborne, ship-borne, and vehicle-mounted electronic equipment require crystal oscillators to provide high-precision frequency references, and the vibration and shock of the substrate will greatly affect the reliability of the crystal oscillator, making its output electrical signal characteristics worse and phase noise increased. Therefore, it cannot meet the requirements of being a high-stable fundamental frequency signal; meanwhile, the acceleration sensitive direction of the crystal oscillator is also an important factor to be considered in the design of the vibration reduction device. The existing rubber ring damper is prone to aging, poor characteristics after vibration, and inconvenient adjustment. Therefore, it is necessary to redesign a crystal vibration dam...
