Background technology
Quartz-crystal resonator is that in hyundai electronics and mechanics of communication, requisite frequency is selected and control core parts.Quartz-crystal resonator is all widely used in military and civilian product, as communication, navigation, household electrical appliances, computer and terminal equipment, various board, bluetooth, wireless mouse, U shield etc.Along with the development of microelectric technique, and integrated circuit is universal, SMD electronic devices and components are inexorable trends of development, and quartz-crystal resonator is a kind of components and parts that are not suitable for integrated morphology, but it is again indispensable Primary Component aspect stabilized frequency, therefore its chip type becomes the problem that people are concerned about.
In electronic applications, generally use electric resistance welding packaged quartz crystal resonator at present, ground lead terminal is put and is welded in base bottom before air-tight packaging, lead-in wire is through insulation spacer opening, make insulation spacer be placed in frame bottom, lead-in wire is bended in inserted shim groove to different directions respectively, be made into surface mount type quartz crystal resonator.Use the Main Function of pad to be: to prevent lead terminal and base bottom short circuit, electric resistance welding quartz crystal is formed to stable support simultaneously.But this surface mount type quartz crystal resonator manufacturing process complexity, production cost is high.
Utility model content
In order to solve above-mentioned quartz-crystal resonator manufacturing process complexity, the shortcoming that production cost is high, the utility model discloses the SMD quartz resonator of a kind of two lead terminal, and the utility model adopts following technical scheme to solve above-mentioned technical problem:
A kind of three pin surface mount type quartz crystal resonators, comprise pedestal, shell, silver electrode quartz plate and two lead terminals, described silver electrode quartz plate is arranged in the cavity housing of pedestal and shell formation, described lead terminal is L shaped, on described pedestal, also comprise glass insulator, described lead terminal passes described pedestal by described glass insulator; Described lead terminal one end is fixed on silver electrode quartz plate by conducting resinl, is parallel to pedestal also and preset clearance between pedestal after the bending of the described lead terminal other end; Also comprise ground lead terminal, described ground lead terminal soldering is in base bottom centre position.
Compared with prior art, the utlity model has following technique effect:
Adopt design of the present utility model, lead terminal can be stablized support quartz-crystal resonator after bending is processed, ensure that again between itself and pedestal, having definite gap has prevented circuit short circuit, without the Surface Mounting Technology that installs insulation board in base bottom surface additional and also can realize quartz-crystal resonator, reduce production cost, ensured the existing performance of quartz-crystal resonator when simplifying production technology; The utility model also comprises ground lead terminal simultaneously, has reduced static and the interference of other noises to quartz-crystal resonator by ground connection, has improved job stability and useful life.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but the utility model is not only confined to following examples.
As shown in Figure 1, a kind of three pin surface mount type quartz crystal resonators, comprise pedestal 10, shell 20, silver electrode quartz plate 30 and lead terminal 60, described silver electrode quartz plate 30 is arranged in the cavity housing that pedestal 10 and shell 20 form, described lead terminal 60 is L shaped, on described pedestal 10, also comprise glass insulator 50, described lead terminal passes described pedestal 10 by described glass insulator 50; Described lead terminal 60 one end are fixed on silver electrode quartz plate 30 by conducting resinl 40, be parallel to after described lead terminal 60 other end bendings pedestal 10 and and pedestal 10 between preset clearance.Pedestal 10 bottom surfaces are also welded with a ground lead terminal 60, and this lead terminal 60 is connected with circuit board ground path.The L shaped lead terminal 60 of bending has three kinds of diverse location relations in quartz-crystal resonator bottom surface: long limit heteropleural, minor face heteropleural, long limit homonymy, corresponding embodiment 1 respectively, embodiment 2, embodiment 3.
Adopt design of the present utility model, lead terminal can be stablized support quartz-crystal resonator after bending is processed, ensure that again between itself and pedestal, having definite gap has prevented circuit short circuit, without the Surface Mounting Technology that installs insulation board in base bottom surface additional and also can realize quartz-crystal resonator, reduce production cost, ensured the existing performance of quartz-crystal resonator when simplifying production technology; The utility model also comprises ground lead terminal simultaneously, has reduced static and the interference of other noises to quartz-crystal resonator by ground connection, has improved job stability and useful life.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
