Abstract
The utility model relates to a resin packaged quartz crystal resonator with novel waterproof materials, which comprises a ceramic base and an upper metal cover. A quartz chip with a silver electrode is arranged inside the ceramic base, the silver electrode of the quartz chip is bonded to an internal electrode of the ceramic base via conductive adhesive, the internal electrode is connected with an external electrode of the ceramic base via a circuit, the ceramic base is in the shape of a flat plate, the upper metal cover is in the shape of a rectangular box, the opening edge of the upper metal cover is coated with resin used for packaging, the ceramic base and the upper metal cover are sealed by the resin for packaging, and sealed periphery of the upper metal cover is coated with ultraviolet optical cement. Resin used for drying and disposed inside the ceramic base originally is changed into ultraviolet optical cement coated on the outside of a crystal so as to resist water, thereby increasing waterproof effect, realizing higher quality stability of the crystal, and implementing the quartz crystal resonant or with low cost, small volume, high-frequency precision and high stability.
Description
Technical field
The utility model relates to quartz-crystal resonator, particularly relates to a kind of new waterproof material resin-encapsulated quartz-crystal resonator.
Background technology
Quick growth along with consumption electronic products (as mobile computer, digital camera, mobile phone, IC smart card etc.), in order to cater to the market demand, low-cost product is the very important ring that dominates the market, but the problem of stability decreases takes place in lower cost materials easily, the crystal oscillator of therefore low-cost, high stability also is to need the big key element that overcomes in design.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new waterproof material resin-encapsulated quartz-crystal resonator, satisfies the application demand in consumption electronic products market.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of new waterproof material resin-encapsulated quartz-crystal resonator is provided, comprise base of ceramic and metal top cover, described base of ceramic inside is equipped with a quartz chip that has a silver electrode, and the silver electrode of sticking together described quartz chip with conducting resinl is to described base of ceramic internal electrode, described internal electrode circuit is connecting described base of ceramic outer electrode, and described base of ceramic is a tabular; Described metal top cover is the rectangular box shape; Coating encapsulation resin on the described metal top cover edge of opening; Described encapsulation with resin with described base of ceramic and described metal top cover involution; The peripheral coating in described metal top cover involution place ultraviolet optical cement.
The volume of described quartz-crystal resonator is 5.0 * 3.2 * 1.0mm or 3.2 * 2.5 * 0.7mm or 2.5 * 2.0 * 0.6mm or 2.0 * 1.6 * 0.45mm.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model use ultraviolet optical cement is coated the quartz-crystal resonator outside and is come waterproof, replace the drying resin that is put in quartz-crystal resonator inside originally, significantly improve waterproof effect, realize the quartz-crystal resonator of low cost, small size, high freuqency accuracy, high stability.
Description of drawings
Fig. 1 is a quartz-crystal resonator structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Execution mode of the present utility model relates to a kind of new waterproof material resin-encapsulated quartz-crystal resonator, comprise base of ceramic 2 and metal top cover 1, described base of ceramic 2 inside are equipped with a quartz chip 3 that has a silver electrode, and the silver electrode of sticking together described quartz chip 3 with conducting resinl 4 is to described base of ceramic 2 internal electrodes, described internal electrode circuit is connecting described base of ceramic 2 outer electrodes, and described base of ceramic 2 is a tabular; Described metal top cover 1 is the rectangular box shape; Coating encapsulation resin 5 on described metal top cover 1 edge of opening; Described encapsulation uses resin 5 with described base of ceramic 2 and described metal top cover 1 involution; The peripheral coating in described metal top cover 1 involution place ultraviolet optical cement 6.The volume of described quartz-crystal resonator is 5.0 * 3.2 * 1.0mm or 3.2 * 2.5 * 0.7mm or 2.5 * 2.0 * 0.6mm or 2.0 * 1.6 * 0.45mm.
Be not difficult to find, the utility model provides a kind of microminiaturized quartz-crystal resonator, on the waterproof material of originally ceramic resin encapsulation crystal, improved, with the drying resin that used originally in quartz-crystal resonator inside, change the ultraviolet optical cement of use into and carry out waterproof in the quartz-crystal resonator outside, improve waterproof effect, allow quartz-crystal resonator reach higher steady quality degree, realized the quartz-crystal resonator of low cost, small size, high freuqency accuracy, high stability.
