Description
Technical field
The utility model relates to a kind of crystal oscillator, particularly a kind of SMD quartz crystal resonator.
Background technology
The traditional quartz-crystal resonator of China is mainly produced by labour-intensive, and its efficiency is low, profit is meagre and production technology does not have substantive breakthroughs, and its size is comparatively large, is mainly used on the low precision electronic products such as toy for children, game machine, television set.
Known attachment quartz-crystal resonator its there is baroque shortcoming, and cost is higher.As the miniaturization along with terminal electronic product, all require miniaturization to components and parts used, the miniaturization of quartz-crystal resonator is also the inexorable trend of development.Current SMD quartz resonator adopts conducting resinl that the spring leaf of the quartz wafer and pedestal that are coated with electrode is bonded together, and add that insulation spacer is made in bottom, complex structure, cost is high.
Utility model content
The purpose of this utility model provides to solve above-mentioned the deficiencies in the prior art a kind of SMD quartz crystal resonator that a kind of volume is little, cost is low.
To achieve these goals, a kind of SMD quartz crystal resonator designed by the utility model, comprise crystal resonator, it is characterized in that: the upper cover that described crystal resonator mainly comprises pedestal and is placed on pedestal, oscillator, metal electrode, wafer and conductive silicon, wafer is placed on pedestal, conductive silicon is placed on oscillator, metal electrode is placed in the upper surface of wafer and is connected with conductive silicon, oscillator is placed between pedestal and wafer, what this pedestal has placement stem draws hole, oscillator is placed in and draws upper end surface, hole, described upper cover and pedestal are sealed by sealing layer of resin between the two, above-mentioned stem one end is placed in be fixed through pedestal and above-mentioned oscillator, the stem end of this end is provided with circular ring plate.
Preferably, described upper cover is that metal material is stamped to form.
A kind of SMD quartz crystal resonator that the utility model obtains, adopt circular ring plate, add the raising bonding strength of wafer and lead-in wire, reach and improve the vibration resistance of product and the object of frequency stability, save raw material, reduce manufacturing cost, there is good economic benefit, described substrate and upper cover are tightly connected by sealing layer of resin, and sealing effectiveness is very good.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: pedestal 1, upper cover 2, wafer 3, conductive silicon 4, metal electrode 5, stem 6, sealing layer of resin 7, oscillator 41, circular ring plate 61.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1, a kind of SMD quartz crystal resonator that the utility model provides, comprise crystal resonator, described crystal resonator mainly comprises pedestal 1 and is placed in the upper cover 2 on pedestal, oscillator 41, metal electrode 5, wafer 3 and conductive silicon 4, wafer 3 is placed on pedestal 1, conductive silicon 4 is placed on oscillator 41, metal electrode 5 is placed in the upper surface of wafer 3 and is connected with conductive silicon 4, oscillator 41 is placed between pedestal 1 and wafer 3, what this pedestal 1 has placement stem 6 draws hole, oscillator 41 is placed in and draws upper end surface, hole, described upper cover 2 is sealed by sealing layer of resin 7 between the two with pedestal 1, above-mentioned stem 6 one end is placed in be fixed through pedestal and above-mentioned oscillator 41, the stem end of this end is provided with circular ring plate 61.
Preferably, described upper cover 2 is stamped to form for metal material.
A kind of SMD quartz crystal resonator that the utility model obtains is described further, adopt circular ring plate or also can take to come directly towards surface and increase twill, the measures such as step, namely design without spring leaf, add the raising bonding strength of wafer and lead-in wire, market miniature requirement can be met, reach and improve the vibration resistance of product and the object of frequency stability, decrease the welding sequence of spring leaf and lead-in wire simultaneously, save raw material, reduce manufacturing cost, there is good economic benefit, described substrate and upper cover are tightly connected by sealing layer of resin, sealing effectiveness is very good, make the frequency of resonator more reliable and more stable.
For utility model person of an ordinary skill in the technical field; under the prerequisite not departing from utility model design; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that claims of being submitted to by utility model are determined.
