Description

Technical Field

[0001] This utility model belongs to the field of resonator technology, and in particular relates to a base for a quartz crystal resonator. Background Technology

[0002] A quartz crystal resonator is an electronic component that utilizes the piezoelectric effect of a quartz crystal to generate a stable frequency. It is widely used in clock signal generation, frequency control, and other applications. Its core is a quartz crystal slice cut to a specific shape. Applying a voltage generates mechanical vibration, forming a high-precision oscillation frequency. It consists of a housing and a base. The housing's main function is to seal and protect the crystal slice from moisture, oxidation, and dust contamination. Therefore, current resonator designs do not consider heat dissipation. However, if used at high power, excessively high temperatures inside the housing can lead to accelerated thermal aging of the crystal slice and system clock synchronization issues. Utility Model Content

[0003] The purpose of this invention is to provide a base for a quartz crystal resonator to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A base for a quartz crystal resonator includes: a housing and a base, wherein a heat-conducting plate is provided in the middle of the bottom of the housing, and the bottom of the housing is connected to the upper part of the base; a heat-conducting plate is provided in the middle of the upper part of the base, the heat-conducting plate is in contact with the heat-conducting plate, the base is hollow inside and a heat exchange device is provided on the base.

[0006] As a further improvement of this utility model, the heat exchange device includes a plurality of heat dissipation holes disposed on the outer wall of the base.

[0007] As a further improvement of this utility model, a plurality of the heat dissipation holes are arranged circumferentially along the base.

[0008] As a further improvement of this utility model, the heat exchange device includes a refrigeration unit disposed inside the base.

[0009] As a further improvement of this utility model, the heat-conducting sheet one and the heat-conducting sheet two are made of copper foil.

[0010] As a further improvement of this utility model, the outer shell is provided with a crystal plate and a shock-absorbing spring damper. The bottom of the shock-absorbing spring damper is connected to the bottom of the outer shell, and the crystal plate is provided on the upper part.

[0011] As a further improvement of this utility model, the outer shell includes a housing and a top cover located on the upper part of the housing. The upper part of the housing is provided with a groove, and the lower part of the top cover is provided with a boss that cooperates with the groove. The boss is fastened in the groove, and the circumference of the boss is provided with an annular sealing strip.

[0012] As a further improvement of this utility model, it also includes pins that are connected to the interior of the housing and pass through the bottom of the housing and the base.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] This invention incorporates two heat-conducting plates with high thermal conductivity on the outer shell and the base. These plates transfer the high temperature inside the outer shell to the base and the low temperature inside the base to the outer shell, facilitating heat exchange and dissipating heat from the outer shell. This effectively reduces the internal temperature of the outer shell, mitigating the problem of accelerated thermal aging of the crystal chip caused by overheating. Consequently, it improves the reliability and stability of the resonator and reduces clock synchronization issues caused by temperature changes, ensuring accurate system operation.
