Abstract
The utility model is related to quartz-crystal resonator technical fields, more particularly, to a kind of microminiature high-frequency quartz crystal resonator, including gold-plated pedestal, crystal shell, lead on built-in crystal base is provided on the gold-plated pedestal, lead is fixedly connected with built-in crystal plate electrode by conducting resinl on the pedestal, and lead passes through plastic insulation gasket to form crystal outer pin under pedestal；The crystal shell is encapsulated in internal formation high vacuum, and keep sealing with gold-plated pedestal using interference fit.The utility model packaging efficiency is high, equipment investment is few, it is excellent to connect electric conductivity, quartz plate and pedestal lead coating are fixed in conductive glue connection, prevent pedestal lead coating tin layers trickling after by temperature from generating loose contact, while pedestal lead Gold plated Layer can be wrapped up effectively when pedestal lead tin coating melts, ensure crystal resonator steady operation.
Description
Technical field
The utility model is related to quartz-crystal resonator technical field, especially a kind of microminiature high frequency Quartz crystal resonant
Device.
Background technology
SMD crystal is process using base of ceramic at present, at least up to ten million members of equipment investment, 1 sealed in unit 1,000,000
Member or so produces 1,000,000 per month, and equipment investment is big, product processing cost is very high.The utility model uses gold-plated pedestal and shell
Interference fit, it is possible to reduce equipment investment is transformed, it is possible to produce in original 49s, cylinder crystal Equipment Foundations；It can
To produce direct plugging-in or SMD type quartz-crystal resonator.
Utility model content
The purpose of this utility model is to overcome above-mentioned technical disadvantages, provide a kind of microminiature high frequency Quartz crystal resonant
Device.
The utility model solve the technical solution that uses of technical problem for：A kind of microminiature high-frequency quartz crystal resonator,
Including gold-plated pedestal, crystal shell, lead on built-in crystal base is provided on the gold-plated pedestal, lead leads on the pedestal
It crosses conducting resinl and is fixedly connected with built-in crystal plate electrode, lead passes through plastic insulation gasket to form crystal outer pin under pedestal.
The crystal shell is encapsulated in internal formation high vacuum, and keep sealing with gold-plated pedestal using interference fit.
Described two outer pins of crystal may be inserted into wiring board installation.
Advantageous effect is possessed by the utility model：
The utility model packaging efficiency is high, and equipment investment is few, and connection electric conductivity is excellent, and quartz plate is fixed in conductive glue connection
With pedestal lead coating, prevent pedestal lead coating tin layers trickling after by temperature from generating loose contact, while pedestal lead Gold plated Layer
It can effectively be wrapped up when pedestal lead tin coating melts, ensure crystal resonator steady operation.
Description of the drawings
Fig. 1 is the internal structure chart of the utility model.
Specific embodiment
The utility model is described below below in conjunction with the accompanying drawings.
As shown in the figure, the utility model includes gold-plated pedestal 5, crystal shell 1, it is provided on the gold-plated pedestal 5 built-in
Lead 7 on crystal base, lead 7 is fixedly connected with built-in crystal plate electrode 4 by conducting resinl 2 on the pedestal, lead under pedestal
Crystal outer pin 3 is formed across plastic insulation gasket；The crystal shell 1 is encapsulated in interior with gold-plated pedestal 5 using interference fit
Portion forms high vacuum, and keeps sealing, and can greatly improve production efficiency in this way；Described two outer pins 3 of crystal can insert
Enter wiring board installation.When being subjected to 240 DEG C to 260 DEG C of high temperature using the quartz-crystal resonator of the utility model, even if in crystal
Crystal lead on coating fusing and outmost Gold plated Layer will not melt, so as to prevent scolding tin trickling cause conducting resinl with
The loose contact of lead on pedestal meets leadless temperature-resistant requirement, realizes attachment metaplasia production.
