Abstract
The utility model discloses a novel constant-temperature crystal oscillator having a built-in temperature compensating function. The structure of the constant-temperature crystal oscillator comprises a TCXO, heating sources 2, a TM temperature inductor 3, a PCB circuit 4, a housing 5 and a base 6; the TCXO is a component which allows a mainly function of oscillation to be realized; the housing 5 and the base 6 are sealed outside the OCTCXO by utilizing cold pressure welding; and the TCXO, the heating sources 2 and the TM temperature inductor 3 are welded on the PCB circuit 4 inside the OCTCXO. The OCTCXO is advantageous in that: 1) the TCXO always works in a constant-temperature enclosed environment, a frequency change brought by temperature is greatly reduced, and stability is improved; and 2) a main vibration circuit also employs the TCXO, and the constant-temperature crystal oscillator employing the TCXO is greatly lowered in cost compared by a constant-temperature crystal oscillator employing an OCXO.
Description
Technical field
The utility model relates to a kind of OCTCXO, particularly relate to quartz oscillator.Belong to technical field of electronic components.
Background technology
Quartz oscillator belongs to high precision electro sub-element, and in the development of quartz oscillator, main flow is designed with VCXO, TCXO, OCXO.Wherein, VCXO frequency-temperature stability is the poorest; TCXO has intermediate frequency-temperature stability; OCXO has good frequency-temperature stability.But OCXO cost is too high; TCXO cost is low, but sometimes in technical indicator, can not meet customer requirement.Urgently release a Novel quartz crystal oscillator, make it simultaneously cheaply, improve frequency-temperature stability.
Summary of the invention
The utility model proposes a kind of OCTCXO, its object is intended to overcome the existing above-mentioned defect of prior art.
Technical solution of the present utility model: its structure comprises components and parts TCXO, heating source, TM temperature inductor, PCB circuit, shell and the pedestal of realizing main oscillation functions, its housing and pedestal are used cold welding to be sealed in the outside of OCTCXO, and the components and parts TCXOTCXO of OCTCXO inside, heating source, TM temperature inductor are welded on PCB circuit.
Advantage of the present utility model: 1) TCXO always works in the closed environment of steady temperature, significantly reduces the frequency change that temperature is brought, and has improved stability; 2) the main circuit that shakes is still used TCXO, and OCXO has significantly reduced cost relatively.
Accompanying drawing explanation
Fig. 1 is the schematic layout pattern of a kind of OCTCXO.
In figure, 1 is TCXO, the 2nd, and heating source, the 3rd, temperature inductor TM, the 4th, PCB circuit, the 5th, shell, the 6th. pedestal.
Embodiment
Contrast accompanying drawing, a kind of OCTCXO, its structure comprises TCXO, heating source 2, TM temperature inductor 3, PCB circuit 4, shell 5 and pedestal 6, and its housing 5 and pedestal 6 are used cold welding to be sealed in outside, and inside is welded on TCXO, heating source 2, TM temperature inductor 3 on PCB circuit 4.
During normal power-up operation, TM temperature inductor 3 converts temperature information to the changing value of resistance, the changing value of resistance converts the variation of electric current to by PCB circuit 4, be used for controlling heating source 2] operating state, under the control of TM temperature inductor 3, heating source 2 is worked always until internal temperature reaches predefined value, PCB circuit 4] middle bridge balance, heating source 2 quits work; To temperature, slightly fall, heating source 2 is task again, and interior environment temperature is constant in predefined value.Meanwhile, TCXO normally works.
