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
The present invention relates to a kind of resonator, relate in particular to a kind of quartz tuning-fork resonator.
Background technology
Quartz wafer is meant on microcosmic is formed that the atom of oxygen and silicon is implicative of each other to arrange alternately and forms, and general quartz wafer is called and is commonly called as crystal, has important use to be worth, and it has piezoelectric effect, and under the alternating force effect, two quartzy faces produce the electric charge of alternations; Under the effect of alternating electric field, quartz wafer produces deformation vibration, the mechanical stress piezoelectric crystal produces electric polarization the piezoelectricity positive-effect, and deformation is back wash effect in electric field for crystalline solid, and the alternating voltage size that produces in the elastic oscillation amplitude of quartz wafer and the crystal matches.The resonator that adopts the tuning fork mode is in existing like product, because that the prong oscillating component at its two ends influences each other is bigger, the poor impact resistance of product, useful life are short; In addition, it is bigger also to exist volume, the defective that power consumption is high.
Summary of the invention
The purpose of this invention is to provide a kind of quartz tuning-fork resonator, with the deficiency that influences each other between the element that overcomes existing product, resistance to impact is relatively poor, power consumption is more, useful life is short.
The objective of the invention is to be achieved through the following technical solutions:
A kind of quartz tuning-fork resonator, comprise quartz wafer, shell, solder stick, kovar ring, lead-in wire, bead and two prongs, described shell is made by the packfong material, described prong places the inside of shell, be respectively equipped with equally distributed quartz wafer on described two prongs, the middle junction of two prongs is a half-circle-arc shape; The center of the tuning fork bottom of prong bottom is embedded with solder stick, and the lower end of welding wire connects lead-in wire; Be provided with kovar ring between the bead of tuning fork bottom and downside, bead is placed in the kovar ring, and shell is close in the side of kovar ring; The lead-in wire that is connected with solder stick passes kovar ring and bead successively and leads to the outside of shell.
The beneficial effect of quartz tuning-fork resonator of the present invention is: oscillating component is combined to be independent of each other separately, can satisfy the needs of user to frequency; Adopt quartz wafer to make that the stability of whole resonator strengthens, the vibrationproof performance is good, useful life is strong; The resistance to impact that vibration frequency is lower, strengthened product has smaller volume, power consumption is more.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the cross-sectional view of the described quartz tuning-fork resonator of the embodiment of the invention.
Among the figure:
