An anti-vibration shock type quartz crystal resonator

Abstract

The invention belongs to the field of electronic resonant components, and in particular relates to a vibration-shock resistant quartz crystal resonator. The present invention at least includes a base and a housing covered on the base, and the base is also provided with two positive lead posts and negative lead posts that penetrate the base and are insulated from each other, and the two lead posts are located on the same side of the quartz wafer. The equal heights on the two lead posts are arranged with jaw-shaped clamping parts for clamping and fixing the quartz wafer to form the horizontal suspension state of the quartz wafer; Corresponding inter-electrode electrical connection arrangements; relative to the fixed clamping end of the fixed lead column of the quartz wafer, a supporting part for supporting the suspended end is provided at the base where the suspended end is located. The present invention can realize its high-efficiency assembly purpose while ensuring its normal working performance, and its assembly efficiency and service life can be further improved.

Description

technical field [0001] The invention belongs to the field of electronic resonant components, and in particular relates to a vibration-shock resistant quartz crystal resonator. Background technique [0002] Quartz crystal resonator is a resonant element made by using the piezoelectric effect of quartz crystal. It can be used together with semiconductor devices and resistance-capacitance elements to form a quartz crystal oscillator. Under the action of an electric field, the quartz crystal produces stress and deformation inside the crystal, thereby generating mechanical vibration and obtaining a specific frequency; if the CPU is regarded as the human heart, the quartz crystal resonator is a cardiac pacemaker, so it is a modern electronic and communication device. It is an essential frequency selection and control core component in technology, and is widely used in various electronic products. [0003] Traditional quartz crystal resonator, its structure is all described in the...

Problems solved by technology

The disadvantages of this structure are: on the one hand, the installation of the quartz wafer only relies on the bonding and fixing of the conductive adhesive. Regardless of the aesthetics after bonding, it is still open to question how effective the fixing method solely relying on the conductive adhesive is.

More importantly, since the two ends of the quartz wafer are bonded and fixed, and the quartz wafer is easily deformed under the action of an electric field, under the action of the huge stress generated when the quartz wafer is deformed, phenomena such as wafer tearing and fracture often occur , thereby greatly shortening the life of the quartz crystal
