Description

Technical Field

[0001] The utility model relates to the technical field of quartz crystal resonators, in particular to a columnar low-frequency quartz crystal resonator. Background Art

[0002] Quartz crystal is a good insulator of electricity, with a resistivity of more than 1000000MΩ.cm. Its chemical properties are extremely stable. It is insoluble in water and acids such as hydrochloric acid, nitric acid, and sulfuric acid at room temperature, and is only soluble in hydrofluoric acid. When heated, quartz crystal can dissolve in alkaline solution. During the use of quartz crystal, the quartz crystal resonator can use the piezoelectric effect of quartz crystal to generate high-precision oscillation frequency. It is an important frequency component for stabilizing and selecting frequency. However, when the quartz crystal inside the quartz crystal resonator is connected and fixed to the pin, the quartz crystal will vibrate. When the amplitude is too large, the quartz crystal may be damaged.

[0003] In order to reduce the amplitude of a quartz crystal, a utility model with patent publication number CN218868206U discloses a quartz crystal resonator, which can easily fix the quartz wafer by providing a fixing structure. When in use, the quartz wafer will be fixed inside a columnar shell, and the quartz wafer will be connected between the second pin and the first pin. The support rod can connect the first pin and the second pin to the quartz wafer together, and the fixing block can fix the support rod. The limiting groove is stuck on the outside of the fixing column and the support rod can be supported inside the columnar shell. The support rod passes through the limiting hole inside the quartz wafer so that the quartz wafer can be fixed inside the columnar shell, which can prevent the quartz wafer from having an excessive amplitude. Although it is convenient to reduce the amplitude of the quartz wafer, it is not convenient to adjust the amplitude frequency of the quartz wafer according to actual needs, and has high limitations during use.
