Abstract
A crystal resonator comprises a pedestal, two spring pieces, a piezoid, and a case cover. The pedestal is of a square shape. The center of the pedestal is provided with two through holes. The periphery of an upper portion of the pedestal is provided with a groove. The spring pieces are downwardly provided with pins. The pins pass through the two through holes of the pedestal. The spring pieces are positioned above an upper end face of the pedestal. Insulators are provided between the spring pieces and the pedestal. End faces of the spring pieces are provided with U-shaped grooves. The piezoid is arranged on the two spring pieces. The case cover is covered on the two spring pieces and the piezoid. A lower edge of the case cover is connected with the pedestal. According to the utility model, the original oval-shaped pedestal is changed into the square-shaped pedestal, the processing is convenient, the positioning is easy, and the size is small; and in addition, the previous using method after a lead is flattened is changed, the lead is used on a product in a surface-mounting method, a circuit board does not need changing, and convenience is brought to use.
Description
Technical field
The utility model relates to the crystal resonator for communication field.
Background technology
At present, being used for the quartz resonator of communication field, a large amount of what use is ceramic packaging series SMD product.Because ceramic difficulty of processing is large, gold-plated cost is high, has brought difficulty for the resonator processing technology, and the process equipment investment is large etc.Therefore, present resonator product brings a high price, and especially the quartz resonator product of China all by external import pottery SMD pedestal, has restricted product and the added value of product of quartz resonator in China basically greatly.
Summary of the invention
The purpose of this utility model is to design a kind of crystal resonator, and is easy to process, locates easily, and size is little.
For achieving the above object, the technical solution of the utility model is:
Crystal resonator, it comprises, pedestal, it is tetragonal structure, and central authorities offer two through holes, and pedestal top periphery is offered groove; Two flat spring sheets, spring leaf is divided into pin, and pin passes two through holes of base pieces, and spring leaf is positioned at top, pedestal upper surface, establishes insulator between spring leaf and the pedestal; The spring leaf end face is offered U-lag; Quartz wafer is arranged on the two flat spring sheets; Cap covers on two flat spring sheets and the quartz wafer, and the cap lower edge is connected with pedestal.
Further, described spring leaf one epitaxial lateral overgrowth is stretched upwards bending again, extension upwards bends and extends again, forms step structure.
Again, described pedestal top circumferential groove upper surface central authorities establish a circle convex tendon.
In addition, be connected by electric resistance welding between cap described in the utility model and the pedestal.
Described pedestal, cap are metal material.
The beneficial effects of the utility model
The utility model is improved to square with original oval-shaped pedestal, and is easy to process, locates easily, and size is little.
The utility model spring leaf is offered U-lag, increases its elasticity, and makes the quartz wafer Stress Release on it, after the quartz wafer energising microvibration is arranged, and guarantees the stability of quartz wafer self frequency with chip architecture of the spring.The attenuation of the utility model pedestal inner flange size, the earth pressure release of operation soldering and sealing behind the assurance product, the course of processing.
The utility model has changed the mode of using after lead-in wire flattens in the past, uses the paster mode instead and is used for product, need not to change wiring board, the convenient use.
Be solidified as a whole by insulator high temperature sintering after the mould assembling between the pedestal matrix of metal material and the pin, quartz wafer and surface be through being connected after by the conducting resinl hot setting between the pedestal matrix of gold-plated processing, is connected by electric resistance welding between the cap that is similarly metal material and the pedestal matrix.
Compared with prior art, the utility model is the resonator of metallic packaging, is further improved in insulation, and its size is dwindled greatly, improved the impact resistance of product, it has the identical technical parameter of ceramic packaging SMD, can form series with the base of ceramic of external import, because its version is consistent with the principle of 49S, processing technology is similar to 49S, so reduced the difficulty of processing of quartz resonator product, reduced cost of manufacture, the process equipment investment is reduced greatly.

Embodiment
Referring to Fig. 1, Fig. 2, crystal resonator of the present utility model, it comprises, pedestal 1, it is tetragonal structure, and central authorities offer two through holes 11,12, and pedestal top periphery is offered groove 13; Two flat spring sheets 2,2 ', spring leaf 2,2 ' is divided into pin 3,3 ', pin 3,3 ' passes two through holes 11 of base pieces, 12, spring leaf 2,2 ' is positioned at pedestal 1 upper surface top, spring leaf 2,2 ' and pedestal 1 between establish insulator 4; Spring leaf 2,2 ' end face are offered U-lag 21,21 '; Quartz wafer 5 is arranged on the two flat spring sheets 2,2 '; Cap 6, cover at two flat spring sheets 2,2 ' and quartz wafer 5 on, cap 6 lower edges 61 are connected with pedestal 1.
Further, described spring leaf 2,2 ' one epitaxial lateral overgrowth are stretched upwards bending again, extension upwards bends and extends again, forms step structure.
Again, described pedestal 1 top circumferential groove 13 upper surface central authorities establish a circle convex tendon 131.
In addition, be connected by electric resistance welding between cap 6 described in the utility model and the pedestal 1.
The utility model is improved to square with original oval-shaped pedestal, and is easy to process, locates easily, and size is little.The U-lag of the utility model spring leaf increases elasticity.Wafer, shell fragment discharge wafer stress, after the wafer energising microvibration are arranged, and guarantee the stability of wafer self frequency with chip architecture of the spring.Pedestal, the attenuation of inner flange size, the earth pressure release of operation soldering and sealing behind the assurance product, the course of processing.The utility model has changed the mode of using after lead-in wire flattens in the past, uses the paster mode instead and is used for product, need not to change wiring board, the convenient use.
