The utility model relates to a
high frequency quartz crystal oscillator belongs to
quartz crystal oscillator technical field, this
high frequency quartz crystal oscillator, include: the base of oscillator and set up above its oscillator shell, through with the parameter mark body of oscillator surface places in the inner recess shell inner wall in protection subassembly, can make parameter mark
body surface lower than oscillator shell plane, avoid in
processing parameter mark body and tool direct contact, set up arc chamfer simultaneously, still can make the oscillator prevent
stress concentration when being impacted, not only has improved the overall strength of inner recess shell, still can guarantee the protection effect of inner recess shell to parameter mark body, through with the parameter mark body of inner recess shell and inside setting up modularization design, on one hand can reduce the process and step of oscillator shell
processing, simultaneously still can be convenient for personnel to remove and shift same type parameter mark body when the subsequent maintenance of oscillator, not only has saved the cost, still can improve the adaptability of product.
