Abstract

The present invention relates to the field of electronic components. Disclosed is a miniaturized SMD crystal oscillator, comprising a housing and a quartz crystal arranged in the housing. The housing is also internally provided with a control circuit board and a switching circuit board. A bottom plate is arranged at the bottom of the housing. The bottom plate is connected to the housing. Long pins and short pins are arranged on the bottom plate. The long pins are electrically connected to the switching circuit board. The long pins are electrically connected to the control circuit board. The short pins are electrically connected to the switching circuit board. The bottom plate and the housing form a closed cavity. The quartz crystal, the control circuit board and the switching circuit board are arranged in the closed cavity. The own size of the SMD crystal oscillator is reduced to make it miniaturized. Moreover, the air tightness of the crystal oscillator is also ensured, and the service life of the crystal oscillator is prolonged.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a miniaturized SMD crystal oscillator. Background technique [0002] In order to adapt to the miniaturization of the volume of various electronic products, improve space utilization and unify the process, SMD crystal oscillators have gradually replaced traditional plug-in crystal oscillators. Existing crystal oscillators are directly connected to the PCB through metal or plastic shells using adhesives or welding. This method cannot guarantee the airtightness of the product. In a humid environment, the moisture will penetrate into the product and corrode the components to cause the product to fail, seriously affecting the reliability and service life of the product. Contents of the invention [0003] The object of the present invention is to provide a miniaturized SMD crystal oscillator, which ensures the airtightness of the crystal oscillator and improves the service life ...
