Damping component, crystal oscillation device, frequency synthesizer and electronic device

Abstract

The invention relates to a metal rubber crystal oscillator damping device. A crystal oscillator is mounted on a bracket; four connecting screw rods with adjustable rigidity and damping are connected with a bottom plate at four corners of the bracket; each connecting screw rod with the adjustable rigidity and damping consists of an adjusting guide pillar, cylindrical metal rubber, a rigid sleeve and a locking sheet, wherein the adjusting guide pillar penetrates through the cylindrical metal rubber, the rigid sleeve and the bracket and is in threaded connection with the locking sheet; a groove is formed in the middle of the bracket; the crystal oscillator is placed in the groove; bosses are arranged on the four corners and are fixedly connected with the rigid sleeves; the cylindrical metal rubber parts are embedded into the rigid sleeves. The device has the advantages that the structure is simple and portable, the installation is convenient, the rigidity and the damping are adjustable, three-dimensional vibration damping performance is excellent, the endurance performance is good, the high temperature resistance, the low temperature resistance and the corrosion resistance are realized, the aging cannot be easily caused, and the like; the practicability is stronger, and the application prospects are wide.

Description

technical field [0001] The invention belongs to the field of vibration reduction, and in particular relates to a vibration reduction component, a crystal oscillator, a frequency synthesizer and electronic equipment. Background technique [0002] Crystal oscillator is the core component of electronic equipment, which can generate the reference oscillation frequency as the reference signal of the electronic equipment. When the electronic equipment needs to use multiple signals, a frequency synthesizer can be used to add, subtract, multiply, and Divide by four arithmetic operations to obtain a series of frequency signals with a certain degree of stability and precision. [0003] In actual work, the vibration of the carrier of the electronic equipment and the vibration caused by the internal components of the electronic equipment will be transmitted to the crystal oscillator, thereby reducing the stability of the oscillation frequency generated by the crystal oscillator, causing...

Problems solved by technology

[0004] In order to reduce the vibration impact of the crystal oscillator, in the prior art, the steel wire rope damping device is often used to damp the crystal oscillator. However, the steel wire rope damping device can only have a vibration damping effect in a single direction, although in general It can meet the requirements of electronic i
