Description

Technical Field

[0001] The utility model relates to the technical field of crystal oscillators, in particular to a vibration-resistant crystal oscillator vibration phase noise test fixture. Background Art

[0002] Some electronic devices require highly stable AC signals, but LC oscillators have poor stability and are prone to frequency drift. A special component, quartz crystal, is used in the oscillator to generate a highly stable signal. This oscillator using quartz crystal is called a crystal oscillator. The crystal oscillator test fixture in the prior art usually uses bolts to fix the crystal oscillator body.

[0003] However, the prior art lacks the function of detachable fixing. In actual use, since the crystal oscillator is not easy to be disassembled when fixed, the manual disassembly of the mounting bolts is cumbersome and the work steps are cumbersome, resulting in low work efficiency.

[0004] Furthermore, the prior art lacks a protective function. In actual use, since the crystal oscillator body is relatively fragile, the crystal oscillator body needs to be protected during testing. The prior art cannot protect the crystal oscillator during testing, resulting in limitations in the prior art. Utility Model Content
