Abstract

The invention discloses a high-vibration-resisting crystal oscillator based on the constant-temperature control, and belongs to the field of electron. The high-vibration-resisting crystal oscillator comprises a metal shielding shell, a vibration isolator which is fixed in the metal shielding shell, and an oscillating system which is arranged on the vibration isolator, wherein the oscillating system is electrically connected with the metal shielding shell. Through the structure, the defect of the existing crystal oscillator that the vibration resistance requirement can not be met under the situation that the size is small can be overcome, and the high-vibration-resisting crystal oscillator is not only small in size and simple in structure, but also strong in vibration resistance and suitable for being popularized to use.

Description

technical field [0001] The invention relates to a crystal oscillator, in particular to a high-vibration-resistant crystal oscillator based on constant temperature control. Background technique [0002] Crystal resonator refers to a quartz crystal resonator made of quartz material. Since the crystal resonator has piezoelectric effect and inverse piezoelectric effect, applying a certain voltage between the two electrodes of the crystal resonator will cause crystal resonance Due to the physical characteristics determined by the material of the crystal resonator itself, the crystal resonator has the characteristics of good frequency stability and is widely used in various electronic products. [0003] According to the piezoelectric effect of the crystal resonator, a crystal oscillator is made. The crystal oscillator is a crystal component that adds an IC to form an oscillation circuit on the basis of the crystal resonator. The crystal oscillator is widely used in various electro...
