Description

Technical Field

[0001] This utility model belongs to the field of crystal oscillator technology, and in particular relates to a matching placement structure for a crystal oscillator. Background Technology

[0002] A crystal oscillator is an electronic oscillator circuit that utilizes the piezoelectric effect of a quartz crystal to generate a stable frequency signal. Based on different implementation technologies, crystal oscillators can be divided into two main categories: active crystal oscillators and passive crystal oscillators. Active crystal oscillators integrate a complete oscillation circuit and amplifier circuit, directly outputting a stable frequency signal without external circuitry. Active crystal oscillators typically have higher frequency stability and lower phase noise, making them suitable for applications requiring high frequency accuracy. Passive crystal oscillators require an external circuit to provide the excitation signal and amplifier circuitry to achieve oscillation. Passive crystal oscillators are relatively inexpensive, but their frequency stability and phase noise performance may not be as good as active crystal oscillators. Due to their high frequency stability, low power consumption, and excellent anti-interference capabilities, crystal oscillators are widely used in various electronic devices. The placement of a crystal oscillator mainly involves its installation and connection in the circuit, as well as its coordination with external circuits. Crystal oscillators are usually used in conjunction with amplifiers and feedback networks to form a stable oscillation circuit.

[0003] The problem with existing technology is that when the crystal oscillator malfunctions or its performance degrades, the inconveniently disassembled casing increases the difficulty of inspection and replacement. Maintenance personnel may need to spend more time and effort to disassemble the casing, and may even have to replace the entire module because it cannot be disassembled, which increases maintenance costs. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a matching placement structure for a crystal oscillator, which has the advantage of facilitating the disassembly of the crystal oscillator housing. This solves the problem that when the crystal oscillator malfunctions or its performance degrades, the inconveniently disassembled housing increases the difficulty of inspection and replacement, and maintenance personnel may need to spend more time and effort to disassemble the housing, or even have to replace the entire module because it cannot be disassembled, thus increasing maintenance costs.

[0005] This utility model is implemented as follows: a crystal oscillator placement structure includes a crystal oscillator and a housing. The crystal oscillator is disposed inside the housing. The housing is divided into a base and a cover. The base is disposed at the bottom of the crystal oscillator. A slot is provided on the top of the base. The cover is inserted into the slot. After the cover and the base are assembled, the crystal oscillator is encapsulated inside. A connection hole is provided on the right side of the cover.

[0006] As a preferred embodiment of this utility model, a protective ring is fixedly connected to the top of the base. The protective ring is disposed on the outer surface of the bottom of the crystal oscillator. By setting the protective ring, the crystal oscillator can be restricted and stably confined to the top of the base to prevent it from moving.

[0007] As a preferred embodiment of this utility model, two dovetail frames are fixedly connected to both the left and right sides of the protective ring, and two dovetail blocks are fixedly connected to both the left and right sides inside the shell cover, with the dovetail blocks corresponding to the dovetail frames. The dovetail blocks are inserted into the outside of the dovetail frames. By setting the dovetail frames and dovetail blocks, the shell cover can be inserted into the dovetail frames on the top of the base through the dovetail blocks when it is assembled with the base, thereby preventing the shell cover from shaking after assembly.

[0008] As a preferred embodiment of this utility model, the left and right sides of the shell cover are provided with limiting grooves, and the left and right sides of the top of the base are fixedly connected with connecting boxes, and the positions of the connecting boxes and the limiting grooves are corresponding. By setting the limiting grooves and connecting boxes, the shell cover can be snapped into place by the connecting boxes on the top of the base, thereby improving the stability of the shell cover after assembly.

[0009] As a preferred embodiment of this utility model, the connecting box has an internal cavity, and a plug-in component is provided inside the cavity. By providing the plug-in component, the shell cover can be plugged into the connecting box, thereby improving the stability of the shell cover.

[0010] In a preferred embodiment of this invention, the plug-in assembly includes a movable plate, two plugs, two compression springs, and two limiting rods. The movable plate is disposed inside the cavity. The two plugs are fixedly connected to the side of the movable plate near the cover, and the other side of the plugs extends through and into the interior of the limiting groove. The two compression springs are fixedly connected to the side of the movable plate away from the plugs, and the other side of the compression springs is fixedly connected to the inner wall of the cavity. The two limiting rods are respectively disposed at the top and bottom of the movable plate, and both sides of the limiting rods are fixedly connected to the inner wall of the cavity. The movable plate is slidably connected to the surface of the limiting rods. By providing the plug-in assembly, after the connecting box contacts the surface of the cover, the plugs can be retracted by the compression of the cover. After encountering the limiting groove, the plugs can be inserted into the limiting groove by the rebound of the compression springs, thereby positioning the cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem that when the crystal oscillator malfunctions or its performance degrades, the inconveniently disassembled outer shell increases the difficulty of inspection and replacement. Maintenance personnel may need to spend more time and effort to disassemble the outer shell, and may even have to replace the entire module because it cannot be disassembled, thus increasing maintenance costs.

[0013] 2. By setting up a plug-in assembly, the plug can be retracted by the squeezing of the shell cover after the connecting box comes into contact with the surface of the shell cover. After encountering the limiting groove, the plug can be inserted into the limiting groove by the rebound of the compression spring, thereby positioning the shell cover. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown in the figure, the present invention provides a crystal oscillator placement structure, including a crystal oscillator 1 and a housing 2. The crystal oscillator 1 is disposed inside the housing 2. The housing 2 is divided into a base 201 and a cover 202. The base 201 is disposed at the bottom of the crystal oscillator 1. A slot 3 is provided on the top of the base 201. The cover 202 is inserted into the slot 3. After the cover 202 and the base 201 are assembled, the crystal oscillator 1 is encapsulated inside. A connection hole 4 is provided on the right side of the cover 202.

[0022] refer to Figure 1 A protective ring 5 is fixedly connected to the top of the base 201, and the protective ring 5 is set on the outer surface of the bottom of the crystal oscillator 1.

[0023] By adopting the above solution, the crystal oscillator 1 can be restricted by setting the protective ring 5, and the crystal oscillator 1 can be stably restricted to the top of the base 201 to prevent it from moving.

[0024] refer to Figure 1 and Figure 3 Two dovetail frames 6 are fixedly connected to both the left and right sides of the protective ring 5. Two dovetail blocks 7 are fixedly connected to both the left and right sides inside the shell cover 202. The dovetail blocks 7 correspond to the dovetail frames 6 and are inserted into the outside of the dovetail frames 6.

[0025] The above solution is adopted: by setting the dovetail frame 6 and the dovetail block 7, the dovetail block 7 can be inserted into the dovetail frame 6 on the top of the base 201 when the cover 202 is assembled with the base 201, thereby preventing the cover 202 from shaking after assembly.

[0026] refer to Figure 3 Limiting grooves 8 are provided on both the left and right sides of the cover 202, and connecting boxes 9 are fixedly connected to both the left and right sides of the top of the base 201, and the positions of the connecting boxes 9 and the limiting grooves 8 are corresponding.

[0027] The above solution is adopted: by setting the limiting groove 8 and the connecting box 9, the shell cover 202 can be snapped into place by the connecting box 9 on the top of the base 201, thereby improving the stability of the shell cover 202 after assembly.

[0028] refer to Figure 4 The connection box 9 has a cavity 10 inside, and the cavity 10 is equipped with a plug-in component 11.

[0029] By adopting the above solution, by setting the plug-in component 11, the shell cover 202 can be plugged into the connecting box 9, thereby improving the stability of the shell cover 202.

[0030] refer to Figure 3 and Figure 4The plug-in assembly 11 includes a movable plate 1101, two plugs 1102, two compression springs 1103, and two limiting rods 1104. The movable plate 1101 is disposed inside the cavity 10. The two plugs 1102 are fixedly connected to the side of the movable plate 1101 near the cover 202, and the other side of the plugs 1102 extends through and into the interior of the limiting groove 8. The two compression springs 1103 are fixedly connected to the side of the movable plate 1101 away from the plugs 1102, and the other side of the compression springs 1103 is fixedly connected to the inner wall of the cavity 10. The two limiting rods 1104 are respectively disposed at the top and bottom of the movable plate 1101, and both sides of the limiting rods 1104 are fixedly connected to the inner wall of the cavity 10. The movable plate 1101 is slidably connected to the surface of the limiting rods 1104.

[0031] Using the above solution: by setting the plug-in assembly 11, after the connecting box 9 comes into contact with the surface of the cover 202, the plug 1102 can be retracted by the squeezing of the cover 202. After encountering the limiting groove 8, the plug 1102 can be inserted into the limiting groove 8 by the rebound of the compression spring 1103, thereby positioning the cover 202.

[0032] The working principle of this utility model:

[0033] In use, the crystal oscillator 1 is placed inside the protective ring 5 on the top of the base 201. Then, the side of the shell cover 202 with the connection hole 4 is aligned with the side of the crystal oscillator 1 with the wiring terminal. The shell cover 202 is then assembled with the base 201. At this time, the dovetail block 7 inside the shell cover 202 is inserted into the dovetail frame 6 on the surface of the protective ring 5. Then, the bottom of the shell cover 202 is inserted into the slot 3 on the top of the base 201. When the insertion is completed, the surface of the shell cover 202 contacts the insertion post 1102 inside the connecting box 9 and presses it, thereby moving the insertion post 1102 and the moving plate 1101 into the cavity 10 and pressing the compression spring 1103. After the shell cover 202 is assembled, the insertion post 1102 is inserted into the limiting groove 8 on the surface of the shell cover 202 by the rebound force of the compression spring 1103, thus completing the assembly of the shell 2.

[0034] In summary, the proposed crystal oscillator's integrated design, through the coordinated use of the crystal oscillator 1, housing 2, base 201, housing cover 202, slot 3, connecting hole 4, protective ring 5, dovetail frame 6, dovetail block 7, limiting groove 8, connecting box 9, cavity 10, plug-in assembly 11, moving plate 1101, insertion post 1102, compression spring 1103, and limiting rod 1104, solves the problem that when the crystal oscillator malfunctions or its performance degrades, the inconveniently disassembled housing increases the difficulty of inspection and replacement. Maintenance personnel may need to spend more time and effort to disassemble the housing, and may even have to replace the entire module due to the inability to disassemble it, thus increasing maintenance costs.
