Description

Technical Field

[0001] The utility model relates to the technical field of crystal oscillators, in particular to a pressure-resistant and waterproof device for a crystal oscillator. Background Art

[0002] A crystal oscillator is an electronic component in an electronic circuit. Some electronic devices require an AC signal with a highly stable frequency, but the LC oscillator has poor stability and is prone to frequency drift (i.e., the frequency of the generated AC signal is prone to change). A special component is used in the oscillator: a quartz crystal, which can generate a highly stable signal. This type of oscillator using a quartz crystal is called a crystal oscillator. Generally, a crystal oscillator consists of an outer shell and a quartz crystal inside it.

[0003] After searching, the application with patent number 202121237586.5 discloses a pressure-resistant and waterproof device for a crystal oscillator, including: a circuit board, two hemispherical covers and a crystal oscillator; the circuit board includes two oppositely arranged board surfaces; the two hemispherical covers are relatively buckled on the two board surfaces to form a closed space; the crystal oscillator is arranged between the circuit board and any hemispherical cover, and is fixedly connected to the circuit board. The present disclosure enables the crystal oscillator to be suitable for working environments with large external pressure and can be suitable for liquid working environments;

[0004] The above application document ensures the pressure resistance and waterproofness of the crystal oscillator through the external connection method. However, during the use of the existing oscillator, it is generally necessary to ensure the sealing and pressure resistance of the shell to prevent external liquid from entering and causing the circuit board and crystal to get damp. At the same time, the pressure deformation of the shell may also cause damage to the crystal and circuit board inside.

[0005] Therefore, we propose a pressure-resistant and waterproof device for a crystal oscillator. Utility Model Content
