Description
Technical field
The present invention relates to crystal oscillator technology, particularly relate to a kind of technology of plum blossom shock-absorbing type antidetonation constant-temperature crystal oscillator.
Background technology
High frequency crystal oscillator is the critical component in electronic equipment, and it is widely used in, in the equipment such as navigation, communication, radar, measuring instrument, being called as " heart " of this class of electronic devices as reference frequency source (reference source).
As shown in Figure 4, traditional crystal oscillator is mainly made up of oscillating circuit board 22 and crystal resonator 25, and each pin of crystal resonator 22 is all directly fixed on oscillating circuit board 25.
When traditional crystal oscillator is worked in vibration environment, the external force such as the vibration that external environment condition produces, centrifugal and impact can be directly transferred on crystal resonator by oscillating circuit board, thereby can cause frequency stability (the being phase noise) variation of crystal resonator.
Summary of the invention
For the defect existing in above-mentioned prior art, technical problem to be solved by this invention is to provide the plum blossom shock-absorbing type antidetonation constant-temperature crystal oscillator that a kind of frequency stability is high.
In order to solve the problems of the technologies described above, a kind of plum blossom shock-absorbing type antidetonation constant-temperature crystal oscillator provided by the present invention, comprise crystal resonator, and be equipped with the oscillating circuit board of oscillating circuit, described crystal resonator is fixed on oscillating circuit board, and be electrically connected with the oscillating circuit on oscillating circuit board, it is characterized in that: also comprise case, fixed head, and at least three have flexible arc line shaped damping steel wire;
Described case and oscillating circuit board are affixed, and cover cap lives crystal resonator, and described fixed head and case are separated from each other;
Each damping steel wire is set as colored shape around case axial symmetry cloth, and the arc top of each damping steel wire is all affixed with fixed head, and the both ends of each damping steel wire are all affixed with case.
Further, on described crystal resonator, be fixed with balancing weight.
Plum blossom shock-absorbing type antidetonation constant-temperature crystal oscillator provided by the invention, case and oscillating circuit board are affixed, and case is arranged on fixed head by the many colored shape shock-damping structures with flexible arc line shaped damping steel wire composition, the external force acting on fixed head can significantly decay after spending shape shock-damping structure buffering, can effectively reduce the impact of external vibration on crystal resonator, its frequency stability will be far above traditional crystal oscillator.

Embodiment
Below in conjunction with brief description of the drawings, embodiments of the invention are described in further detail, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof, all should list protection scope of the present invention in.
As shown in Figure 1-Figure 3, a kind of plum blossom shock-absorbing type antidetonation constant-temperature crystal oscillator that the embodiment of the present invention provides, comprise crystal resonator 5, and be equipped with the oscillating circuit board 2 of oscillating circuit, described crystal resonator 5 is fixed on oscillating circuit board 2, and be electrically connected with the oscillating circuit on oscillating circuit board, it is characterized in that: also comprise case 6, fixed head 1, and four have flexible arc line shaped damping steel wire 3;
Described case 6 is affixed with oscillating circuit board 2, and cover cap lives crystal resonator 5, and described fixed head 1 is separated from each other with case 6;
Each damping steel wire 3 is set as colored shape around case 6 axial symmetry cloth, and the arc top of each damping steel wire 3 is all affixed with fixed head 1, and the both ends of each damping steel wire 3 are all affixed with case 6.
In the embodiment of the present invention, on described crystal resonator 5, be fixed with balancing weight 4, the weight of crystal resonator 5 one sides is increased to some extent, can promote damping, buffering effect.
The embodiment of the present invention is applicable to being arranged on the electronic equipment of needs reference frequency source and uses, when installation, fixed head is directly fixed on electronic equipment, and all unsettled settings of case and oscillating circuit board, making to conduct by electronic equipment the external force of coming can only act directly on fixed head, while work in vibration environment, the external force acting on fixed head conducts to by fixed head the colored shape shock-damping structure that each damping steel wire forms, after flower shape shock-damping structure buffering, conduct to oscillating circuit board and crystal resonator again, External Force Acting while conducting to crystal resonator is significantly decayed by flower shape shock-damping structure, thereby less on the impact of crystal resonator, the frequency stability of crystal resonator is also relatively high.
The traditional crystal oscillator that the embodiment of the present invention is compared same frequency in frequency stability improves significantly, taking the crystal oscillator of 10MHz frequency as example, under the acceleration environment of 1g sine wave, the stationary value of frequency is at 0.2ppb/g, and the frequency stability value of traditional crystal oscillator is at 1ppb/g.
