Abstract
The invention discloses a high-overload resistant quartz crystal element comprising a base (1), a bracket (2), a contact spring ring (3), a crystal wafer (4), upper and lower silver electrode films (5) and a shell (6). The bracket (2) is arranged on the base (1) and connected with the base (1). The crystal wafer (4) is arranged in the bracket (2), the edge of the crystal wafer (4) is in three-point contact with the bracket (2), the crystal wafer (4) and the bracket (2) are fixed, the contact spring ring (3) is welded on a lead post of the base (1) and connected with the upper and lower silver electrode films (5), and the base (1) is connected with the shell (6). The high-overload resistant quartz crystal element is an overload resistant quartz crystal element with the overload resistant accelerated speed of 20000g and has the advantages of high stability and safe, reliable and small product structure and is suitable for mass production within a wide temperature range. Because of high stability and reliability, the high-overload resistant quartz crystal element is suitable for being used in special occasions such as artillery, an unmanned aerial vehicle and the like. The high-overload resistant quartz crystal element has high structure sealing strength and can be used for well controlling the moisture content inside a product.
Description
Technical field
The present invention relates to a kind of quartz crystal unit, is a kind of anti high overload quartz crystal unit, is applicable under the high acceleration condition to do frequency source, tracking target and clock device in unmanned plane navigation, the cannon weaponry guidance system.
Background technology
At present, quartz crystal unit has been widely used in technical fields such as communication, Aeronautics and Astronautics, electronic technology and Device and Meters.Mainly be used as the clock or the standard frequency source of these complete machines; The quartz crystal unit that in cannon guidance, guiding are guided as signal source, plays a crucial role proposes special requirement; (3000g～the quartz crystal unit structure adopts spring or spring leaf to do the fixing of crystal cartridge 50000g) and at present promptly to quartz crystal unit the anti high overload impact capacity will to be arranged; The quartz crystal unit anti-overload ability of this structure fabrication is lower, generally can only reach the level of tens g to the acceleration of hundreds of g.Quartz crystal unit to required usefulness in unmanned plane navigation and the cannon guidance then requires acceleration (the unidirectional disposable impact of single shaft) will reach several ten thousand g; Therefore the quartz crystal unit structure of using in the market can't satisfy the requirement of complete machine antagonism high acceleration; Organizational equipment all will lean on import to solve, and abroad China weapons aspect is restricted always.
Summary of the invention
The technical problem that the present invention will solve provides a kind of anti high overload quartz crystal unit; Providing a kind of directly pastes crystal wafer and is fixed in the base on the carriage; Have the anti high overload acceleration and reach the overload-resistant quartz crystal unit of 20000g, have high stability, reliable, the miniaturization of product structure.Be applicable to that work is produced in batches under the wide temperature (60 ℃～100 ℃).
The present invention constitutes like this: it is by base, carriage, contact spring circle, crystal wafer, silver electrode film, shell six parts constitute up and down.Be provided with carriage above the base, carriage is evenly distributed on the base with bikini, and carriage is connected with base.Crystal wafer is inserted in the carriage, and the crystal wafer edge contacts with 3 on carriage, and is fixedly connected with carriage.Crystal wafer is a wafer design, and top and bottom are the silver electrode film.The contact spring coil is connected with the stem of base, contacts spring coil and is fixedly connected with silver electrode film up and down again.Base, shell are circular configuration, and two weldering muscle are arranged on the base, and base is connected encapsulation with shell.
Advantage of the present invention is:
1. the present invention directly is bonded in crystal wafer in the base on the carriage.Therefore the electrical property of quartz crystal unit and the activity of self have not only been solved; Improved simultaneously the intensity of anti high overload (impact acceleration) again; Can realize high stable, the high reliability of performance up to several ten thousand g, satisfy cannon, unmanned plane etc. and use in special (high acceleration) occasion.The shock test report sees attached list 1.
2. the present invention adopts shell and base metallic resistance sealing dress, and sealing structure intensity is high.Under technology guarantees, product internal steam content (is superior to 5000 * 10
-6) better controlled arranged.Frequency stability is superior in-60 ℃～100 ℃ temperature ranges ± and 40 * 10
-6, high low temperature frequency stabilization examining report sees attached list 2.
3. the present invention is designed to round structure, and manufacture craft is ripe, is convenient to produce in batches.
