Description

Technical Field

[0001] The utility model belongs to the field of quartz crystal resonators, and in particular relates to a vibration testing device for a crystal oscillator assembly. Background Art

[0002] A quartz crystal oscillator, or crystal oscillator for short, is made based on the principle that when the frequency of an electrical signal is equal to the natural frequency of the quartz crystal, a quartz crystal will resonate. Based on this characteristic, it is often used in LC oscillation circuits or filters. At the same time, because the crystal oscillator has the characteristics of small size and high stability, the manufacturing process of the crystal oscillator is very demanding. Therefore, after the crystal oscillator is manufactured, a vibration test is required on the crystal oscillator assembly to detect whether the performance of the crystal oscillator assembly can meet the standards after the vibration.

[0003] In the process of vibration testing of a crystal oscillator assembly, a clamp is usually required to fix the crystal oscillator assembly. After the vibration process is completed, the crystal oscillator is taken out and tested. The existing clamp usually only places the crystal oscillator assembly in two upper and lower clamps, and then connects the two clamps with a number of screws to fix the crystal oscillator assembly. However, this fixing method requires manual screwing, which increases the detection time and labor costs. It may be difficult to ensure the fixing effect of the crystal oscillator assembly by other methods. Therefore, a clamp for vibration testing that is simple to operate and has a good fixing effect is needed. The utility model solves this technical problem. Utility Model Content
