Description

Technical Field

[0001] The utility model relates to the field of electronic resonant components, in particular to an impact-resistant and earthquake-resistant crystal resonator. Background Art

[0002] A crystal resonator is a resonant component made by using the piezoelectric effect of a quartz crystal. When used together with semiconductor devices and resistor-capacitor components, a quartz crystal oscillator can be formed. Under the action of an electric field, stress is generated inside the crystal, causing deformation and thus generating mechanical vibration to obtain a specific frequency. If the CPU is regarded as the human heart, the quartz crystal resonator is the heart pacemaker. Therefore, it is an essential core component for frequency selection and control in modern electronics and communication technologies and is widely used in various electronic products.

[0003] At present, a crystal resonator utilizes the piezoelectric effect and resonant characteristics of a quartz crystal to generate a stable electromagnetic oscillation through a feedback loop. When a voltage is applied to the quartz crystal, the crystal wafer will generate mechanical oscillation due to the piezoelectric effect. This oscillation will form an electric field in the crystal wafer, generating reverse charges. These reverse charges will in turn affect the oscillation of the crystal wafer, forming a closed oscillation loop, and finally performing external connection work through the action of the pins.

[0004] There are certain deficiencies in the current crystal resonator. First, in the prior art, when connecting the quartz crystal inside the housing, most of them directly connect the pins to the quartz crystal, and then the pins are connected to and led out from the base through insulators. After being impacted, it is easy to cause damage and detachment of the quartz crystal, resulting in the failure of the entire resonator. Moreover, in the current crystal resonator, there is an insulator between the externally connected pins and the base. When the pins are impacted, the connection between the pins and the base is prone to breakage, which will cause damage to the resonator and bring unnecessary trouble to subsequent work. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an impact-resistant and earthquake-resistant crystal resonator, aiming to improve the problems that the existing crystal cannot resist earthquakes and the connection between the pins and the base is prone to breakage.

[0007] As a further description of the above technical solution: One side of the second spring is fixedly connected to the side wall of the intermediate block, and the bottom of the telescopic rod is fixedly connected to the top of the intermediate block;

[0013] As a further description of the above technical solution: The crystal chip and the support plate are arranged inside the housing, and the pins are symmetrically arranged at the bottom of the base.

[0014] The present utility model has the following beneficial effects:
