Abstract
The utility model relates to a quartz resonator base spring piece which belongs to the technical field of quartz resonator structures, and is a component of a quartz resonator and is characterized by changing the hollow metal spring piece of the existing U-shaped groove (9) into a spring piece with an arc groove or long groove (10), namely the arc groove or the long groove is arranged on the metal spring piece; and the arc grooves or the long grooves of a group of spring pieces which are positioned at the same quartz resonator are bilaterally symmetrical. As for the quartz resonator base spring piece, the existing U-shaped groove is changed into arc or long groove, which leads the spring piece not to vibrate with a circuit board easily by reduction of the flexibility of the spring piece, thereby greatly reducing the generation probability of vibration noise and reducing the influence of noise signals on the work circuit.

The common processing method of quartz resonator is elder generation's silver electrode on the evaporation of quartz plate two sides; be placed on then on the pedestal metal spring sheet; two ends use silver conductive adhesive behind hot setting quartz plate and the reliable circuit of the fixing formation of reed to be connected; again encapsulating shell on the pedestal metal base plate, with the structure division in the seal protection cavity.When quartz resonator was worked, the resonant electrical signals that quartz plate produced was connected with external circuit with lead-in wire by metal spring leaf, used insulator to fix between metal lead wire and the base plate, played insulating effect.
Form in the member at quartz resonator, metal spring leaf directly contacts with quartz plate, have and support and the circuit interconnect function, the pedestal metal spring leaf that in industry extensively adopts has adopted the design of " U type groove " hollow out at present, make metal spring leaf have certain elasticity, to reduce the electrical characteristics influence of stress that the outside applies, as shown in Figure 4 to quartz resonator.But use the quartz resonator of this " U type groove " hollow out design metal spring sheet to be welded on when working on the circuit board, under certain condition, quartz resonator hollow out metal spring sheet easily and circuit board vibrate together, make quartz resonator generation vibration and noise signals, influence the operate as normal of circuit.
Three, summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned " U type groove " hollow out metal spring sheet exists, provide a kind of and can reduce elasticity, be not easy to produce vibration, thereby significantly reduce vibration noise, reduce quartz resonator pedestal spring leaf the operating circuit influence with circuit board.
A kind of quartz resonator pedestal spring leaf of the present utility model, assembly for quartz resonator, quartz resonator comprises that the upper end is provided with the metal base plate 1 of metal shell 8, metal lead wire 3 passes metal base plate 1, and it is fixed by the inner set insulator of metal base plate 14, the upper end that metal lead wire 3 passes metal base plate 1 is connected with metal spring sheet 2, metal spring sheet 2 is connected with the quartz plate 7 that the upper and lower surface on top applies silver electrode 6 by silver conductive adhesive 5, special character is the hollow out metal spring sheet of original U type groove 9 is changed into the reed of band arc shaped groove or elongate slot 10, be that the metal spring sheet is provided with arc shaped groove or elongate slot 10, the perforated area of arc shaped groove or elongate slot 10 dwindles, to reduce the elasticity of metal spring sheet 2; The arc shaped groove or the elongate slot 10 that are arranged in one group of spring leaf of same quartz resonator are left-right symmetric (shown in Fig. 8,9), to keep balance;
Above-mentioned arc shaped groove or elongate slot 10 are on the pad 11 and the metal spring sheet between its homonymy quartz plate silver conductive adhesive 5 of metal lead wire 3, thereby shorten moment between the quartz plate strong point and the spring leaf greatly and (shown in Fig. 4,5, contrast L2＜L1), reduce moment to reduce the elasticity of metal spring sheet 2.
For further enlarging accommodation, above-mentioned arc shaped groove or elongate slot 10 can also be the type groove of other regular shapes;
Be further to enlarge accommodation, above-mentioned arc shaped groove or elongate slot 10 can also be on the metal spring sheets between the free end 12 of the solder joint 11 of metal lead wire 3 and metal spring sheet.
A kind of quartz resonator pedestal of the utility model spring leaf, changing existing U type groove shape is arc shaped groove or elongate slot shape, by reducing the elasticity of spring leaf, make spring leaf be not easy to produce vibration with circuit board, thereby significantly reduced the probability that vibration noise produces, reduced the influence of noise signal operating circuit.
