Quartz tuning-fork resonator

Abstract

The invention relates to a quartz tuning fork resonator, which comprises quartz wafers, a housing, a tin solder wire, a Kovar ring, a lead, a glass bead and tuning fork arms. The quartz tuning fork resonator is characterized in that the entire housing is made of nickel silver; an entire tuning fork is arranged in the housing; the quartz wafers are uniformly distributed on the two tuning form arms respectively; the middle connection section of the tuning form arms has a semi-arc shape; the tin solder wire is inlaid in the center position on the bottom of the tuning fork; and the lead is connected with the lower end of the solder tin wire. The Kovar ring is arranged between the bottom of the tuning form and the glass bead therebelow; the glass bead is sheathed in the Kovar ring; the side surface of the Kovar ring is tightly attached with the housing; and the lead connected with the tin solder wire is extracted out of the housing sequentially through the Kovar ring and the glass bead. The quartz tuning fork resonator has the advantages that: the vibration sections are combined with each other without influencing each other; the adoption of the quartz wafers can enhance the stability and the anti-vibration performance and prolong the service life of the entire resonator; and the resonator has lower vibration frequency, enhanced impact resistance, smaller size and larger power consumption.

Description

Technical field [0001] The invention relates to a resonator, in particular to a quartz tuning fork resonator. Background technique [0002] The microscopic composition of the quartz wafer refers to the arrangement of oxygen and silicon atoms intertwined with each other. The general quartz wafer is called crystal, which has important application value. It has a piezoelectric effect. Under the action of alternating force, the two components of quartz Each surface produces alternating charges; under the action of an alternating electric field, the quartz wafer produces deformation and vibration, and the mechanical stress piezoelectric crystal produces electric polarization called the piezoelectric positive effect, and the crystal deformation in the electric field is called the inverse effect, and the elasticity of the quartz wafer The amplitude of the oscillation is consistent with the magnitude of the AC voltage generated in the crystal. In the existing similar products of the tuni...
