Description

Technical Field

[0001] The utility model relates to the technical field of quartz crystal processing, in particular to a quartz crystal resonator. Background Art

[0002] Quartz crystals can be made into quartz crystal resonators by using their piezoelectric resonance characteristics. In a resonator, a quartz crystal is cut into a specific shape and size, and an alternating voltage is applied to its two electrodes. When the frequency of the applied voltage is the same as the natural frequency of the crystal, the crystal begins to vibrate, and the frequency of the vibration is the same as the frequency of the applied voltage. Quartz crystal resonators are often used in electronic devices to generate stable oscillation signals. For example, in clock circuits, frequency synthesizers, and oscillators, by adjusting the size and shape of the crystal, its natural frequency can be changed, thereby achieving control of the frequency of the oscillation signal.

[0003] When working, the existing quartz crystal resonator needs to realize the vibration of the crystal plate through the mutual cooperation of electrodes to complete the required mechanical vibration. However, strong mechanical vibration or impact may cause physical deformation of the quartz crystal and the electrode connection, thereby affecting the stability of its resonant frequency. Therefore, a reliable and stable quartz crystal resonator is needed. Utility Model Content

The protective shell is provided with a mounting plate that is close to the top of the damping shock absorber, and the mounting plate is penetrated by multiple mounting bolts that are threadedly connected to the damping shock absorber, so as to facilitate the installation and disassembly operations of the protective shell, and the cooperation of the damping shock absorber can buffer the vibration generated by the device.

[0007] As an improvement, the outer wall of the protective shell is provided with a waterproof groove matching the left electrode and the right electrode. The setting of the waterproof groove facilitates the installation and removal of the left electrode and the right electrode, and the waterproof material reduces the risk of electrode damage.

The connecting wire passes through the first limiting sleeve, the buckle and the second limiting sleeve in sequence and is connected to the right electrode. While the buckle is used to limit and fix the connecting wire, the connecting wire is limited at both ends of the buckle by the first limiting sleeve and the second limiting sleeve to avoid falling due to shaking and reduce the risk of damage to the connecting wire due to vibration.
