Background The crystal oscillator is used as a core electronic element for generating accurate frequency signals, is widely applied to the fields of communication equipment, industrial control modules, automobile electronic systems, aerospace instruments and the like, the running precision of downstream electronic equipment is directly determined by the stability of output frequency, and in the application scenes of continuous or impact vibration of vehicles, engineering machinery, rail transit and the like, the vibration resistance of the crystal oscillator is a key technical index for guaranteeing the long-term stable operation of the crystal oscillator, so that the crystal oscillator with a reliable vibration-resistant structure becomes one of the core requirements of the fields. In the prior art, the basic structure of a crystal oscillator generally comprises a mounting base for bearing an integral part, a crystal element of a core frequency generation unit and pins for realizing electric connection, and in order to cope with vibration environment, various basic anti-vibration design schemes have been developed in the industry, wherein in the early stage, elastic buffer pieces (such as rubber pads and silica gel sheets) made of single materials are paved between the mounting base and the crystal element, part of vibration energy is absorbed through deformation of the elastic materials, along with the upgrading of the requirements, a simple metal spring or an elastic sheet is added at the periphery of the crystal element in part of improvement schemes, the buffer capacity of the spring for horizontal vibration is enhanced by utilizing the expansion and contraction characteristics of the spring, and in addition, the rigidity of the base itself is improved by thickening the side wall of the mounting base or adopting alloy materials so as to reduce the transmission of external vibration to the crystal element. However, the prior schemes still have obvious technical defects in practical application, and are difficult to meet the use requirements of high-reliability scenes, namely, firstly, from the perspective of shock resistance comprehensiveness, a single elastic buffer piece or a simple spring structure is designed for vibration in a certain specific direction, the omnibearing protection of horizontal, vertical and oblique multidimensional vibration of a crystal element cannot be realized, when complex multidirectional vibration is encountered, the uncouffered vibration energy easily causes damage of the internal structure of the crystal element or drop of a pin welding spot, further causes faults such as frequency drift and signal interruption, and seriously influences the operation stability of equipment; In addition, in some schemes, the crystal element is bonded with the mounting base by adopting glue or is connected by adopting a non-detachable buckle, when the crystal element breaks down and needs to be maintained and replaced, the mounting base or the crystal element needs to be destroyed to complete disassembly, the operation is complex, the maintenance cost is high, and the requirement on convenience of equipment later maintenance is difficult to adapt. In summary, the vibration-resistant design of the existing crystal oscillator has obvious short plates in terms of protection dimension, pin suitability and disassembly and maintenance, and cannot fully meet the comprehensive requirements of high stability, high reliability and easy maintenance of the crystal oscillator in a vibration environment, so that the research and development of a crystal oscillator structure with omnibearing vibration resistance, capability of stably supporting pins and convenience in disassembly and maintenance becomes a technical problem to be solved in the field.
