Description

Technical Field

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

[0002] In many electronic systems, such as communication equipment and computer clock circuits, the frequency accuracy of signals is crucial. If the frequency of a quartz crystal resonator deviates, it can cause errors in the modulation, demodulation, and synchronization processes of the signal, thereby affecting the performance of the entire system.

[0003] Existing quartz crystal resonators mostly employ a metal casing assembly structure, making their temperature prone to drop in low-temperature environments. The physical properties of quartz crystals are closely related to temperature; at low temperatures, parameters such as the elastic constant, density, and dielectric constant of the quartz crystal change. These changes lead to alterations in the resonant frequency of the quartz crystal. For example, as the temperature decreases, the elastic modulus of the quartz crystal may increase, causing a change in the crystal's vibration velocity, thereby altering its resonant frequency and resulting in inaccurate output signals. Therefore, this application designs a miniature quartz crystal resonator to address these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small quartz crystal resonator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a small quartz crystal resonator, comprising a protective cover and a base plate, wherein the protective cover is snapped onto the base plate, a mounting plate is glued to the lower end of the base plate, a limiting mounting seat is provided at the upper end of the base plate, and a limiting mounting component is provided on the limiting mounting seat.

[0006] Preferably, the upper end of the base plate is symmetrically provided with limiting buckles for engaging the protective cover, and the limiting buckles are inverted L-shaped straight plate structures.

[0007] Preferably, the limiting installation assembly includes an installation enclosure and an electric heating wire horizontally disposed on the installation enclosure, a resonator horizontally mounted in the middle of the installation enclosure, and a heat-insulating and conductive film horizontally mounted at the top of the installation enclosure.

[0008] Preferably, the limiting mounting base has a slot for inserting into and adhesively fixing the installation enclosure, and the inner wall of the protective cover has several shock-absorbing springs at equal intervals for abutting and supporting the installation enclosure.

[0009] Preferably, a raised retaining ring is glued to the mounting plate, and a shock-absorbing pad for matching the raised retaining ring is protruding from the lower end surface of the base plate.

[0010] Preferably, the lower end of the resonator is provided with multiple leads extending to the upper surface of the mounting plate at equal intervals.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the combination of shock-absorbing springs and anti-vibration pads provides a stable anti-vibration effect for the quartz crystal resonator, thereby improving the vibration stability of the device and realizing the function of stable support and protection for the quartz crystal resonator. Furthermore, the combination of electric heating wire and heat-insulating conductive film to prevent heat loss facilitates further increase in the operating temperature of the quartz crystal resonator, thus enabling the function of maintaining the operating temperature at low temperatures. The heat-insulating conductive film also reduces the heating effect of the external low-temperature environment on the electric heating wire. Ultimately, this solves the problem of inaccurate output signals caused by changes in the operating frequency of existing quartz crystal resonators in low-temperature environments.

[0020] Example: See Figure 1-5 This utility model discloses a small quartz crystal resonator, comprising a protective shell cover 1 and a base plate 2. The protective shell cover 1 is snapped onto the base plate 2. A mounting plate 3 is glued to the lower end of the base plate 2, and a limiting mounting seat 5 is provided at the upper end of the base plate 2. The limiting mounting seat 5 is provided with a limiting mounting assembly. Through the arrangement of the base plate 2 and the mounting plate 3, the resonator can be installed more stably. The upper end of the base plate 2 is symmetrically provided with limiting buckles 4 for snapping onto the protective shell cover 1. The limiting buckles 4 are inverted L-shaped straight plate structures. Through the setting of the limiting buckles 4, the protective shell cover 1 can squeeze the limiting buckles 4, causing deformation on the limiting buckles 4, thereby pressing the protective shell cover 1 into the limiting buckles 4 for fixation. The limiting mounting assembly includes a mounting baffle 9 and an electric heating wire 6 horizontally provided on the mounting baffle 9. The resonator is horizontally mounted in the middle of the mounting baffle 9. A heat-insulating and conductive film 8 is horizontally installed at the top.

The limiting mounting base 5 has a slot 10 for inserting into the mounting enclosure 9 for adhesive fixation. Several shock-absorbing springs 7 are equidistantly arranged on the inner wall of the protective shell cover 1 to abut and support the mounting enclosure 9. The shock-absorbing springs 7 can cooperate with the mounting enclosure 9 to reduce the transmission of vibration to the resonator. A raised retaining ring 12 is glued on the mounting plate 3. The lower end surface of the base plate 2 is provided with a shock-absorbing pad 11 for cooperating with the raised retaining ring 12. The shock-absorbing pad 11 can improve the vibration resistance of the resonator. Multiple leads 13 are equidistantly arranged at the lower end of the resonator, extending to the upper end surface of the mounting plate 3. The leads 13 can better connect the resonator for signal transmission.

[0021] Working principle: When using this utility model, firstly, the resonator is snapped into the mounting enclosure 9. The heat-insulating conductive film 8 at the top of the mounting enclosure 9 can better improve the heating effect of the electric heating wire 6. The electric heating wire 6 on the mounting enclosure 9 can heat the installation area of ​​the resonator, thereby maintaining the stability of the resonator's working temperature. Next, the mounting enclosure 9 is inserted into the slot 10 with fixing adhesive and glued in place. Then, the protective shell cover 1 with shock-absorbing spring 7 is installed in the limit buckle 4. Finally, the anti-vibration pad 11 is glued to the bottom end face of the base plate 2, and the base plate 2 is installed and fixed on the mounting plate 3. The use of the device is then completed.
