Abstract
The utility model discloses a quartz-crystal resonator comprising an outer-shell, wherein a quartz wafer with an inlaid silver electrode and a quartz plate holder fixed on a pedestal which are arranged in the outer-shell, the quartz plate holder is a symmetrical vertical metal plate, a V-shaped groove is arranged on the top of the quartz plate holder, the quartz wafer is inserted in the V-shaped groove vertically, the silver electrode enchased in the quartz wafer is connected with the quartz plate holder through a conducting adhesive point, and the structure of the quartz plate holder is curved-typed. As using the above structure, the symmetrical vertical quartz plate holder makes the quartz wafer keep the vertical structure instead of prior procumbent structure, thereby assembly is convenient, the rate of finished products is improved and the performance of productions of a same batch is uniform. The quartz crystal plane parallels the force direction and can not be damaged easily when receiving impact, meanwhile both sides of the quartz wafer are relative equilibrium, and the quartz-crystal resonator can be suitable for bigger temperature differential range and work stably in worse operating environment.
Description
Technical field
The utility model relates to a kind of quartz-crystal resonator.
Background technology
Quartz oscillator is the oscillator of high accuracy and high stability, be widely used in all kinds of oscillating circuits such as colour TV, computer, remote controller, and be used for frequency generator in the communication system, provide reference signal for the data processing equipment clocking with for particular system.Its basic comprising roughly is: downcut thin slice from a quartz crystal by certain azimuth, the coating silver layer respectively welds a lead-in wire and receives on the pin as electrode on each electrode on its two corresponding surfaces, adds package casing and constitutes.Fig. 1 is shown in Figure 2, is existing quartz-crystal resonator structure.This quartz-crystal resonator is on the streamline of manufacturing, and the operator need control the quartz wafer that studs with silver electrode in the assembly line general and be tiled on the chip support.Then two end points of chip support are compressed, make quartz wafer fix.Quartz wafer is tiled in the easy deviation in position on the chip support, causes with a collection of properties of product disunity.Simultaneously the last operation that compresses quartz wafer is easy to the quartz wafer of fragility is damaged, and makes decrease in yield.The position of Gu Ding quartz wafer makes the quartz-crystal resonator internal structure very unstable like this, though assemble the chlamydate protection in back, in case fall, wherein Cui Ruo quartz wafer plane is vertically stressed, quite easily fracture.Under simultaneously such structure, the space that the quartz wafer two sides is kept is asymmetric, and the working temperature of quartz-crystal resonator is restricted, and service behaviour is also unstable.
Summary of the invention
It is unified that the technical problems to be solved in the utility model provides a kind of same batch products performance, the rate of finished products height, and shock resistance, and operating temperature range is big, the quartz oscillator of stable work in work.
For reaching described purpose, a kind of quartz-crystal resonator of the utility model, comprise shell, stud with the quartz wafer of silver electrode in being provided with in the shell and be fixed on chip support on the pedestal, described chip support is the upright metallic sheet of symmetry, the chip support top has the V-type groove, and described quartz wafer uprightly is inserted in the described V-type groove.
Preferably, the described silver electrode that is embedded in the quartz wafer is connected with chip support by adhesive dots.Such structure is guaranteeing that constitutionally stable while between quartz wafer and the chip support also makes between quartz wafer and the chip support conduction good.
Preferably, described crystal cartridge is bent type structure.Such structure can further be alleviated the injury that accidental shock brings quartz wafer.
Owing to adopted above structure, the upright chip support of symmetry makes quartz wafer change tiling structure for many years, and becomes rising structure, is convenient to install, and has improved rate of finished products.The performance of unified batch products is comparatively unified.When being subjected to impacting, be subjected to force direction to be parallel to the quartz crystal plane, be difficult for suffering damage.Quartz wafer two sides relative equilibrium can adapt to bigger temperature range simultaneously, still can steady operation in worse operational environment.

Embodiment
As shown in Figure 3, Figure 4, a kind of quartz-crystal resonator of the utility model, comprise shell 1, stud with the quartz wafer 2 of silver electrode 21 in being provided with in the shell 1 and be fixed on chip support 3 on the pedestal 4, described chip support 3 is the upright metallic sheet of symmetry, chip support 3 tops have V-type groove 31, and described quartz wafer 2 uprightly is inserted in the described V-type groove 31.
On the streamline of manufacturing, the operator only need control assembly line will in stud with silver electrode 21 quartz wafer 2 be inserted in the V-type groove 31 of the chip support 3 that is fixed on the pedestal 4, go up adhesive dots 5 again and just can put shell 1 manufacturing and finish.With respect to existing flush system quartz-crystal resonator, needn't worry that there is deviation the position that quartz wafer 2 is placed, also reduced the process that chip support 3 tops are compressed, make same batch products performance unified, rate of finished products also is improved.Because quartz wafer 2 uprightly is inserted in the V-type groove 31, has not only improved the impact resistance of quartz wafer 2, and make that two space of planes of quartz wafer 2 are symmetrical relatively, increased the operating temperature range of quartz-crystal resonator greatly.
Described crystal cartridge 3 is bent type structure.When quartz-crystal resonator falls accidentally, can further give the leeway of quartz wafer 2 bufferings, improve the impact resistance of quartz-crystal resonator.
Above specific embodiment is for explanation of the present utility model, rather than for qualification of the present utility model.Change and distortion that those skilled in the art make according to the utility model only otherwise break away from spirit of the present utility model, all should belong to protection range of the present utility model.
