[0001] The utility model provides a compact double-slot constant temperature crystal oscillator, belonging to the technical field related to crystal oscillators. Background Art

[0002] Quartz crystal resonator is abbreviated as quartz crystal or crystal oscillator. It is an electronic component that uses the piezoelectric effect of quartz crystal (also known as crystal) to generate high-precision oscillation frequency. It is a passive component. The component is mainly composed of quartz wafer, base, shell, silver glue, silver and other components. The full name of crystal oscillator is crystal oscillator, which refers to a thin slice (referred to as wafer) cut from a quartz crystal at a certain azimuth angle. Quartz crystal resonator is referred to as quartz crystal or crystal, crystal oscillator; and the crystal component with IC added inside the package to form an oscillation circuit is called crystal oscillator. Its products are generally packaged in metal shells, and some are packaged in glass shells, ceramics or plastics.

[0003] Based on the above, the inventors found that:

[0004] In the prior art, there is a phenomenon that the crystal oscillator cannot dissipate heat when the heat sink of the heat dissipation component is damaged or aged, which increases the sensitivity of the crystal to the ambient temperature, thereby affecting the frequency jitter characteristics and frequency stability of the crystal oscillator output, resulting in unstable performance.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a compact double-slot constant temperature crystal oscillator is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the traditional crystal oscillator cannot dissipate heat when the heat conducting sheet is damaged or aged, which leads to unstable crystal performance.

[0007] In order to solve the above problems, the utility model proposes a technical solution: a compact double-slot constant temperature crystal oscillator, including a shell, a PCB board, a crystal oscillator body, a data processing system, a temperature sensor, a sensor, and a controller. The crystal oscillator body is placed in the shell, and a heat dissipation component is arranged in the shell, and the heat dissipation component includes a cover plate, a breathable net, a frame, and a lifting component. The shell is provided with a groove and the frame is placed in the groove. The four corners on the inner side of the shell are respectively provided with placement grooves, and the placement grooves are connected to the grooves.

[0008] Furthermore, the frame is a square structure and four sides of the frame are respectively provided with through grooves, the breathable net is embedded in the through grooves and fixedly connected to the inner wall thereof, the frame is placed at the lower end of the cover plate and fixedly connected thereto, and the cover plate covers the shell.

[0009] Furthermore, two moving blocks 1 and two moving blocks 2 are respectively arranged at the four inner corners of the frame, the two moving blocks 1 are located at diagonal positions of the shell, and the two moving blocks 2 are located at another diagonal position of the shell.

[0010] Furthermore, the moving block 1 and the moving block 2 are both L-shaped structures and are placed in the placement groove, and the moving block 1 is movably connected in the placement groove.

[0013] Due to the adoption of the above-mentioned technical scheme, the beneficial effects of the compact double-slot constant temperature crystal oscillator of the utility model are as follows: through the setting of the heat dissipation component, the starting motor indirectly drives the frame and the air permeable net to move out of the groove, so that the cover body is at a distance from the shell, and the heat inside the shell is discharged from the air permeable net, so that it can assist the heat dissipation component matched with the crystal oscillator body to dissipate heat, thereby ensuring the stability of the crystal performance, so that it can be better used.

[0027] The principle of the compact double-slot constant temperature crystal oscillator of the utility model is:

[0028] The PCB board, temperature sensor, sensor, and controller are all placed in the shell. The dual-slot constant temperature function is realized through the PCB. The temperature sensor senses the temperature and transmits the temperature value to the data processing system. The temperature limit value is set. When the value exceeds the limit value, it is transmitted to the controller through the sensor. When the temperature exceeds the limit value, the controller controls the motor to turn on. When the temperature is lower than the limit value, the controller controls the motor to turn off. The above can be achieved through the existing technology, so the utility model does not make a detailed description.

[0029] When in use, the motor drives the threaded rod and the moving block 2 upward or downward, so that the moving plate 1 moves in the placement slot, the frame moves in the groove, the air-permeable net is moved out of the groove, and the heat inside the shell is discharged through the air-permeable net. Figure 2 As shown by the arrows, the two lifting components ultimately achieve the technical goal of moving the cover body upward or downward. When the cover body is covered on the shell, the interior of the shell is in a sealed state.

[0030] The utility model can assist the heat dissipation component matched with the crystal oscillator body to dissipate heat through the arrangement of the heat dissipation component, thereby ensuring the stability of the crystal performance.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
