Technical field
The present invention relates to quartz oscillator field, particularly a kind of H types temperature compensating type quartz oscillator.
Background technology
Quartz-crystal resonator is referred to as crystal oscillator, and it is utilized made of the quartz crystal slice with piezo-electric effect.It is this
Quartz crystal slice can produce mechanical oscillation when being acted on by applied alternating field, when the frequency and quartz crystal of alternating electric field
When intrinsic frequency is identical, stable frequency will be exported.
Temperature compensating type quartz oscillator is that temperature-compensated chip and quartz-crystal resonator are encapsulated in one by one kind
The quartz oscillator risen.The H type temperature compensating type quartz oscillator temperature-compensated chips are encapsulated in quartz crystal
Together, the frequency accuracy in whole temperature province is improved, is usually used in communication and intelligence system.
The content of the invention
A kind of the shortcomings that it is an object of the invention to overcome prior art, there is provided H types temperature compensating type quartz crystal vibration
Device.
The purpose of the present invention is achieved through the following technical solutions：A kind of H types temperature compensating type quartz oscillator, bag
Include base of ceramic, quartz crystal, temperature-compensated chip, the upper surface of described base of ceramic offers main groove, recessed in master
Trench bottom opens up fluted, one step of formation in groove, step of the quartz crystal one end by glue point installed in main groove
On, quartz crystal is obliquely installed, and offers auxiliary groove in the lower surface of base of ceramic, temperature-compensating core is placed with auxiliary groove
Piece, temperature-compensated chip are placed in the upper surface of auxiliary groove, are provided with below temperature-compensated chip for protecting temperature-compensating
The packed layer of chip.
Specifically, conductive pole, one end of conductive pole are installed on the base of ceramic between described main groove and auxiliary groove
It is connected with quartz crystal, the other end of conductive pole is connected with temperature-compensated chip.
Specifically, by being welded to connect between described conductive pole and temperature-compensated chip.
Specifically, it is provided with seal cover board on described main groove.
Beneficial effects of the present invention are as follows：Quartz crystal and temperature-compensated chip are encapsulated in less thickness range
Together, the only thin ceramics of phase alternating floor are made between quartz wafer and compensation chips, ceramics have good heat conductivility, such stone
Temperature consistency between English chip and temperature compensation chip is very good, is advantageous to lift the whole warm area of temperature compensating crystal oscillator
Frequency accuracy.
Brief description of the drawings
