Anti-vibration impact type quartz crystal resonator

Abstract

The invention belongs to the field of electronic resonant elements, and particularly relates to an anti-vibration impact type quartz crystal resonator. The anti-vibration impact type quartz crystal resonator at least comprises a base and a shell covering on the base. The base is also provided with a positive lead post and a negative lead post, which penetrate through the base and are insulating to each other. Both the positive lead post and the negative lead pose are arranged at the same side of a quartz crystal wafer. Jaw-shaped clamping parts for clamping and fixing the quartz crystal wafer are arranged on the positive lead post and the negative lead post at the same height so as to enable the quartz crystal wafer to be at a horizontal suspension state. The jaw-shaped clamping parts at corresponding lead posts are respectively electrically connected with corresponding electrodes on the quartz crystal wafer. Relative to a fixing clamping end of the fixing lead post of the quartz crystal wafer, a support part for supporting a suspension end is arranged on the base where the suspension end is. While guaranteeing the normal working performance, the anti-vibration impact type quartz crystal resonator can achieve the purpose of efficient assemble, and both the assemble efficiency and service life of the resonator 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
