Abstract
The invention proposes a crystal oscillator using an airbag for shock absorption. The airbag is disposed between the crystal oscillator and a housing. Because of the resilience of the airbag, friction of air inside the airbag can consume the energy of oscillation. The airbag can thus isolate oscillation than a spring or rubber and achieve better shock absorption effect. Such a crystal oscillator using the airbag for shock absorption can be applied to electronic devices like an aircraft, a ground motion vehicle and revolving equipment in various oscillation occasions.
Description
Technical field

Background technology
Crystal oscillator application at present is the most universal, but owing to crystal oscillator has effect of acceleration, in the case of having acceleration, crystal oscillator output performance deteriorates, and has had a strong impact on the performance of electronic equipment.In order to reduce the impact of acceleration, it is developed multiple shock-dampening method.As patent " for communication in moving and the constant-temperature crystal oscillator of trailer-mounted radar " (application number: CN201220054584.7) proposes to use spring isolation vibration, patent " a kind of crystal oscillator damping device " (application number: CN20130218199.0) to propose to use cushion pad isolation vibration.But what these dampings used is all elastomeric material, there is resonance point.When frequency of vibration is close to resonant frequency, not only shake the most suppressed, be exaggerated on the contrary.Under wideband spectrum is vibrated, due to frequency of vibration width, resonance point is difficult to avoid.Therefore damping effect is undesirable.
Summary of the invention
In order to more preferably reach damping effect, the present invention proposes a kind of crystal oscillator using bag restraint.Air bag is arranged between crystal oscillator and housing.Owing to air bag has elasticity, in air bag, the friction of gas can consume vibrational energy, therefore can preferably isolate vibration than spring and rubber, reach more preferable damping effect.
The technical scheme is that crystal oscillator is mainly made up of housing, cap, air bag, internal crystal oscillator, lead-out terminal.Housing is square shell, uses metal material Milling Process to make, is above provided with lead-out terminal；Cap is arranged on housing, and making is a closed area inside agitator；Air bag is made up of with thin mold materials metal column, and thin-film material have employed deformable structure, is respectively fitted over up and down on metal column；Having pore or air inlet and gas outlet, air inlet and gas outlet to be fitted with one-way cock on air bag, when air bag pressurized, air inlet open, gas outlet is closed；When air bag tension, gas outlet is opened, inlet close；One metal column of air bag is fixed on housing, and crystal oscillator is then fixed on another metal column.Lead-out terminal can be radio frequency (RF) coaxial connector, insulator, feedthrough capacitor or ground terminal, it is achieved the function that internal crystal oscillation signal is drawn.
When housing is given a shock, air bag is given vent to anger by air inlet and is absorbed the energy of vibrations, the vibrations of absorbing external so that the internal actual vibrations born of crystal oscillator are greatly lowered, and the most still can keep internal crystal oscillator output frequency degree of stability in acceptable accuracy rating.
The advantage of this invention is make use of the cushioning ability of air bag, owing to air bag consumes vibration energy, resonance free point, the vibrations of some frequency will not be amplified, all can obtain good damping effect, be with a wide range of applications in whole frequency range.
