Description

Technical Field

[0001] This utility model relates to the field of crystal resonator technology, specifically a stable quartz crystal resonator. Background Technology

[0002] A quartz crystal resonator is an electronic component that utilizes the piezoelectric effect of quartz crystals to generate high-precision oscillation frequencies. It is a passive component, primarily composed of a quartz crystal wafer, a base, a housing, silver paste, and silver. Based on the lead configuration, it can be divided into through-hole and surface-mount types. The working principle of a quartz crystal resonator is based on the piezoelectric effect. It involves cutting a quartz crystal into different shapes at specific azimuth angles, coating two opposite surfaces with silver layers as electrodes, soldering leads as pins, and finally encapsulating it in a housing. When the frequency of the applied alternating voltage equals the natural vibration frequency of the quartz crystal, resonance occurs, producing a resonant phenomenon. This resonance phenomenon allows the quartz crystal resonator to provide a stable and high-precision oscillation frequency. Quartz crystal resonators are mainly used in frequency control and frequency selection circuits.

[0003] Some existing resonators are fixed to the base by adhesive bonding. This connection method is susceptible to external forces, which can cause gaps at the connection point, resulting in pin deformation and damage. This, in turn, affects the connection between the pins and external components and signal transmission, thus impacting the frequency control performance of the crystal resonator during use. In addition, quartz crystals are prone to failure due to temperature and force during long-term use, requiring replacement. Existing packaging methods, which integrate the internal crystal and components, make it difficult to quickly disassemble and install the outer shell, affecting overall replacement work and ease of use. Therefore, we propose a stable quartz crystal resonator to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a stable quartz crystal resonator that solves the problems of existing quartz crystal resonators being difficult to disassemble, replace, and install quickly during use, and the connection positions being prone to loosening, which affects the working effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a stable quartz crystal resonator, comprising a housing structure. The housing structure includes a casing with a mounting hole on its top and a cover plate mounted on the top. A quartz crystal resonator structure is installed inside the casing. The quartz crystal resonator structure includes a quartz crystal wafer with electrodes on both sides. Pins are connected to the electrodes, and a base is fitted around the pins. Fixing components are mounted on both sides of the base. Each fixing component includes a mounting frame with mounting seats connected to both sides. A circular groove is installed inside the mounting frame, and a fixing block is movably mounted inside the circular groove.

[0007] By setting a quick-release housing connection method, the housing is connected to the cover plate and internal components through the mounting holes on the top of the housing and the cooperation of screws and retaining rings. This makes it easy to regularly maintain and replace the quartz crystal, extending the overall service life of the resonator, and making the disassembly and installation of the quartz crystal resonator more convenient.

[0008] Furthermore, mounting holes are evenly distributed around the top of the housing, extending into the interior of the housing. A screw is movably fitted inside the mounting hole, extending to the top of the housing and fixedly connected to a nut.

[0009] Furthermore, each screw is movably fitted with a fixing ring, which is movably connected to the top of the cover plate. The cover plate is movably installed at the same size as the top of the housing, and the bottom of the housing is movably connected to the top of the base in the quartz crystal resonator structure.

[0010] Furthermore, both sides of the bottom of the base are movably sleeved with the top of the pins. The pins include two sets, and electrodes are symmetrically welded to the outside of the pins. A quartz crystal is movably installed in the middle of the electrodes. The pins extend to the outside of the bottom surface of the housing. An insulating sleeve is movably sleeved on the outside of the pins. The outside of the insulating sleeve is movably sleeved with the base. The top of the base has symmetrical through holes on both sides. The through holes are adapted to fit the insulating sleeve. The insulating sleeve extends to the bottom of the base. Both sides of the outside of the base are movably installed with the fixing bracket in the fixing assembly.

[0011] The mounting components are installed on both sides of the base via mounting brackets. The fit between the circular groove and the mounting block strengthens the connection between the internal quartz crystal resonator structure and the base, thereby ensuring the stable oscillation of the quartz crystal wafer, electrodes, and pins during operation and achieving overall stability.

[0012] Furthermore, mounting bases are fixedly connected to both sides of the outer side of the fixing frame. The top of the mounting base has an opening, which is movably connected to the outer surface of the base by fixing bolts. A circular groove is fixedly installed at the center of the inner side of the fixing frame. Grooves are symmetrically opened on both sides of the outer side of the circular groove. The grooves are movably adapted to the fixing block. A connecting rod is fixedly installed at the center of the top of the fixing block.

[0013] Furthermore, the outer sides of the housing are provided with round holes, the inner walls of the round holes are movably connected to the outside of the connecting rod, and a movable cover is fixedly installed on the top of the connecting rod, the movable cover being installed on the outside of the housing.

[0014] This utility model has the following beneficial effects:

[0015] (1) This utility model: By setting a quick-release housing connection method, the housing is connected to the cover plate and internal components through the mounting hole on the top of the housing and the cooperation of the screw and the fixing ring.

[0027] Please see Figures 1-5 As shown, this utility model is a stable quartz crystal resonator, including a housing structure 1, which includes a housing 101. The top of the housing 101 has a mounting hole 102, and a cover plate 103 is installed on the top of the housing 101. A quartz crystal resonator structure 2 is installed inside the housing 101. The quartz crystal resonator structure 2 includes a quartz crystal 201, with electrodes 202 on both sides of the quartz crystal 201. The electrodes 202 are connected to pins 203, and a base 204 is sleeved on the outside of the pins 203. Fixing components 3 are installed on both sides of the base 204. The fixing components 3 include a fixing frame 301, with mounting seats 303 connected to both sides of the fixing frame 301. A circular groove 302 is installed inside the fixing frame 301, and a fixing block 304 is movably installed inside the circular groove 302.

[0028] By setting a quick-release housing 101 connection method, the housing 101 is connected to the cover plate 103 and internal components through the mounting hole 102 on the top of the housing 101, the screw 104 and the fixing ring, making it easy to regularly maintain and replace the quartz crystal 201, extending the overall service life of the resonator, and making the disassembly and installation of the quartz crystal resonator more convenient.

[0029] Mounting holes 102 are evenly provided around the top of the housing 101. The mounting holes 102 extend into the interior of the housing 101. A screw 104 is movably fitted inside the mounting holes 102. The screw 104 extends to the top of the housing 101 and is fixedly connected to the nut 105. Through the movable connection between the housing 101 and the cover plate 103, the housing 101 and the internal components can be quickly disassembled and installed.

[0030] Each screw 104 is movably fitted with a fixing ring, which is movably connected to the top of the cover plate 103. The cover plate 103 is movably installed at the same size as the top of the housing 101. The bottom of the housing 101 is movably connected to the top of the base 204 in the quartz crystal resonator structure 2. By setting the fixing ring, the tightness of the connection between the cover plate 103 and the housing 101 is strengthened, forming a sealed space.

[0031] The base 204 has two bottom sides that are movably connected to the top of the pins 203. The pins 203 include two sets. Electrodes 202 are symmetrically welded to the outside of the pins 203. A quartz crystal 201 is movably installed in the middle of the electrode 202. The pins 203 extend to the outside of the bottom surface of the housing 101. Insulating sleeves 205 are movably fitted to the outside of the pins 203. The outside of the insulating sleeves 205 is movably connected to the base 204. The base 204 has two symmetrical through holes on the top sides. The through holes are adapted to fit the insulating sleeves 205. The insulating sleeves 205 extend to the bottom of the base 204. The base 204 has two outer sides that are movably installed to the fixing brackets 301 in the fixing assembly 3.

[0032] The fixing component 3 is installed on both sides of the base 204 through the fixing bracket 301. With the engagement of the circular groove 302 and the fixing block 304, the internal quartz crystal resonator structure 2 is strengthened and tightly connected to the base 204, thereby ensuring the oscillation stability of the quartz crystal 201, electrode 202 and pin 203 during operation, thus achieving overall stability.

[0033] Mounting seats 303 are fixedly connected to both sides of the fixed frame 301. The top of the mounting seat 303 has an opening, which is movably connected to the outer surface of the base 204 by fixing bolts. A circular groove 302 is fixedly installed in the center of the fixed frame 301. The circular groove 302 has symmetrical grooves on both sides of its outer side. The grooves are movably adapted to the fixing block 304. A connecting rod 305 is fixedly installed in the center of the top of the fixing block 304. Through the cooperation of the mounting seats 303 and the fixing bolts, the fixed frame 301 is connected to the outside of the base 204, which facilitates the installation of the fixing block 304.

[0034] Both sides of the outer side of the housing 101 are provided with round holes. The inner wall of the round holes is movably connected to the outside of the connecting rod 305. A movable cover 306 is fixedly installed on the top of the connecting rod 305. The movable cover 306 is installed on the outside of the housing 101. By controlling the connecting rod 305 and the movable cover 306, the opening and closing state of the fixed block 304 and the inside of the round groove 302 is achieved, thereby realizing the effect of fixing the internal components.

[0035] Working principle: During use, the housing 101 engages with the screw 104 through the mounting holes 102 distributed around its perimeter to press and fix the cover plate 103, forming a sealed cavity. The floating design of the fixing ring ensures even pressure distribution on the cover plate 103, preventing uneven stress on the crystal. The movable connection between the housing 101 and the cover plate 103 allows for quick installation and removal of the housing 101, cover plate 103, and quartz crystal resonator structure 2, facilitating replacement. The quartz crystal 201 is soldered to the pins 203 via electrodes 202 on both sides. The pins 203 pass through the insulating sleeve 205 of the base 204 for electrical isolation. The fixing bracket 301... The mounting base 303 is connected to the base 204 by the fixing bolts. The fixing block 304 in the inner circular groove 302 can slide along the groove to absorb external mechanical stress. When subjected to external impact, the fixing block 304 slides in the circular groove 302. The welding process of the electrode 202 and the pin 203 avoids stress concentration and ensures the stability of electrical signal transmission. The external circuit applies an alternating electric field to the electrode 202 through the pin 203 to excite the piezoelectric effect of the quartz crystal 201 and generate a stable resonant frequency. The fixing component 3 is set up and the base 204 and the internal component are connected and fixed to enhance the stability of the internal component, thereby improving the oscillation stability effect.
