Description

technical field [0001] The invention relates to the field of crystal oscillator devices, in particular to a crystal oscillator with an efficient heat dissipation effect. Background technique [0002] Some electronic devices require AC signals with a highly stable frequency, but the LC oscillator has poor stability and the frequency is easy to drift (that is, the frequency of the generated AC signal is easy to change). A special component—quartz crystal is used in the oscillator, which can generate Highly stable signal, this type of oscillator using a quartz crystal is called a crystal oscillator. [0003] The traditional constant temperature crystal oscillator usually fixes the crystal resonator directly on the printed circuit board, or pastes it on the printed circuit board through thermal adhesive, or places a pad between the crystal resonator and the printed circuit board. layer metal sheet, and finally use the heating block arranged near the crystal resonator or near th...

Problems solved by technology

[0004] The object of the present invention is to provide a crystal oscillator with high-efficiency heat dissipation effect. When the user first uses it, the crystal oscillator is connected to the PCB board, and the pins of the crystal oscillator are fixed through the pin holes reserved on the PCB board. The heat dissipation silicon grease is applied in the hollow groove of the board, which can prevent excessive heat generated by daily use and absorb the heat generated by it. The bottom grooves on both sides can accelerate the frequency of gas exchange. The water pipe can actively absorb the heat generated, and the coolant in the pipe can reduce the temperature of the water pipe, and then absorb the external temperature through the water pipe to achieve the effect of rapid cooling. The temperature sensor installed in the outer cover can display the internal temperature change , it is convenient for the user to lower the temperature to the specified temperature during use, which is convenient for the user to detect. At the same time, the user can also heat the inside of the outer cover through the heating resistor at the top of the inner side of the cover to maintain a constant temperature. The user can put the pin After being fixed at the specified position, the snap ring is set on the threaded structure, and when the pin is fixed, it can play a buffering effect, and then the pin is fixed to improve the structural stability, so as to solve the problem proposed in the above background technology. The existing heating block heats the crystal resonator unevenly, and sometimes the crystal is subjected to thermal stress due to uneven heating, which instead increases the sensitivity of the crystal to the ambient temperature, which in turn affects the output frequency jitter of the crystal oscillator Characteristics and frequency stability issues
