The invention relates to a tuning fork type quartz-crystal resonator which comprises an enclosure with an opening at one end, a U-shaped quartz wafer and a base for sealing the opening of the enclosure, wherein the enclosure is formed by stamping copper-nickel-zinc alloy; one end of the enclosure is closed, and the other end of the enclosure is an open cylinder; and an outer circumferential nickel layer and an inner circumferential nickel layer are arranged on the outer circumferential surface and the inner circumferential surface of the enclosure respectively. The tuning fork type quartz-crystal resonator provided by the invention is reasonable in structure, easy to produce, lower in cost and stable in quality; and the enclosure in sleeve joint has high air tightness and does not burst easily.
Description
Technical field
The present invention relates to a kind of tuning fork-type quartz crystal resonator, belong to technical field of electronic components.
Background technology
The tuning fork-type quartz crystal resonator of prior art comprises the shell of an end opening, U-shaped quartz wafer and the pedestal that seals for the opening with shell, its lead-in wire is welded and fixed with the installing electrodes on U-shaped quartz wafer surface, the tuning-fork-type quartz wafer is positioned in the shell, pedestal is installed in the aperture position of shell, and the tuning-fork-type quartz wafer is sealed in the shell.But the tuning fork-type quartz crystal resonator unreasonable structure of prior art be not easy to produce, thereby cost is higher, and there is some problems in quality stability
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructure, be easy to produce, cost is lower, the shell of steady quality, socket has good air-tightness and be difficult for the tuning fork-type quartz crystal resonator of spalling.
Technical scheme of the present invention is: a kind of tuning fork-type quartz crystal resonator comprises the shell of an end opening, U-shaped quartz wafer and the pedestal that seals for the opening with shell; Described shell is stamped to form by packfong; Shell shape is end sealing, and the other end is the cylinder of opening; On the outer peripheral face of shell He on the inner peripheral surface outer peripheral face nickel dam and inner peripheral surface nickel dam are arranged respectively.
Further technical scheme is:
Described tuning fork-type quartz crystal resonator, its outer peripheral face nickel dam and the inner peripheral surface nickel dam nickel dam for electroplating.
