Description

Technical Field

[0001] The utility model relates to the field of crystal resonators, and more specifically, to a quartz crystal oscillator assembly. Background Art

[0002] Crystal resonators are made based on the principle that when the frequency of an electrical signal is equal to the natural frequency of a quartz crystal plate, a quartz crystal plate will resonate. Based on this characteristic, they are often used in LC oscillation circuits or filters. A crystal resonator includes a quartz crystal plate disposed inside and a crystal oscillator assembly that accommodates the quartz crystal plate. The crystal oscillator assembly is provided with a circuit structure that is used to provide an electrical signal to the two conductive electrodes of the quartz crystal plate to cause the quartz crystal plate to resonate.

[0003] In the prior art, some crystal oscillator assemblies are provided with conductive holes on the assembly base to enable conduction between the two sides of the assembly base, thereby realizing power supply to the two conductive electrodes of the quartz crystal piece. The conductive holes are usually provided below the conductive piece that contacts the two conductive electrodes of the quartz crystal piece. As the crystal resonator is used for a long time, the filler in the conductive holes will expand, thereby causing the sealing environment of the assembled quartz crystal piece to be destroyed, thereby reducing the service life of the crystal resonator.
