Technical field

The present invention relates to a kind of electronic devices and components, particularly belong to a kind of Minitype quartz-crystal resonator.

Background technology

Based on the continuous renewal of product in the electron trade, the miniaturization of electronic devices and components, microminiaturized requirement are proposed constantly.But determine owing to consist of the modular construction of quartz-crystal resonator, in processing and production technology, need to reserve enough size and space, so that the size of above-mentioned parts itself can not be accomplished very little, and then cause the miniaturization of quartz-crystal resonator integral body that great difficulty is arranged, can not satisfy the miniaturization that modern electronic product proposes, microminiaturized requirement.

Summary of the invention

The object of the present invention is to provide a kind of novel small crystal resonator, further dwindle small product size to reach, save material, satisfy miniaturization of electronic products, microminiaturized purpose.

Small crystal resonator provided by the present invention, comprise substrate, insulator, wire, quartz wafer and shell, insulator is placed in the on-chip insulator placement hole, wire passes the wire perforation on the insulator, and wire termination connects quartz wafer, and substrate top is coated with shell, it is characterized in that, be provided with an insulator placement hole on the described substrate, correspondingly, be provided with two wire perforation on the described insulator.

Small crystal resonator provided by the present invention, when assembling is used, insulator is placed in the on-chip insulator placement hole, and two wires pass respectively two wires perforation on the insulator, and sealing is fixed as the crystal resonator pedestal through sintering process fusing insulator.Because the variation of insulator and substrate structure, simplified the difficulty of whole assembling, processing, therefore, the physical dimension of product and installation dimension have all obtained further dwindling, greatly reduce the volume of raw-material consumption and product, have compact conformation, economize on resources, improve the good effect of properties of product.
