The invention discloses a crystal oscillator damping device based on flexible reeds. First flexible reeds and second flexible reeds are arranged on four side faces of a crystal oscillator in a central symmetry mode respectively. Adjusting screw rods and adjusting nuts are connected with spiral pairs, and all other parts are connected through bolts. According to the crystal oscillator damping device, the damping function is achieved through the first flexible reeds and the second flexible reeds, the damping rigidity is adjusted through spiral mechanisms formed by the adjusting screw rods and the adjusting nuts, the first flexible reeds and the second flexible reeds are formed by machining high-elasticity impact-resistant spring steel, and a better damping effect can be achieved. Furthermore, the crystal oscillator damping device is compact in structure, rich in shapes of the flexible reeds, larger in design space, wide in applicability, good in damping performance, resistant to high temperature and low temperature, resistant to corrosion and not prone to aging, the rigidity is easy to adjust, and the device has wide application prospects and very high practicability.
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...
