Title:
DIRECTLY-HEATING OVEN CONTROLLED CRYSTAL OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2017/015834
Kind Code:
A1
Abstract:
The present invention relates to the technical field of quartz crystal oscillators, and particularly, to a directly-heating oven controlled crystal oscillator. In the present invention, the surface of a wafer is provided with wires, two ends of each wire are respectively connected to one end of a support column located inside a mounting space, and the other end of the support column located outside the mounting space is connected to a wafer pin. Accordingly the wires on the surface of the wafer are connected to an external circuit by means of the support columns and the wafer pins, and the wires emit heat to heat the wafer after the wires are electrified by the external circuit. In the directly-heating oven controlled crystal oscillator provided in the present invention, an extra wafer heating component does not need to be assembled inside the crystal oscillator, the wafer can be heated just by arranging the wires on the surface of the wafer one time, in addition, because the wires heat the wafer in a direct-contact manner, waste of heating power consumption is avoided, and heating power consumption of the wafer is reduced on the whole.
