Background technology
Quartz-crystal resonator is the piezoelectric device made from piezoelectric quartz (promptly quartzy), and it not only has high stability physical and chemical performance, and the elastic vibration loss is minimum.Compare with other electronic devices and components, piezoelectric quartz crystal also has very high frequency stability and high Q value, the important components and parts that make it become stabilized frequency and select frequency.Along with the extensive use of digitizer, market is also more and more higher to chip type, miniaturization, high frequency stability and some specific (special) requirements of crystal element and device.For example its encapsulation specification of UM-1, UM-5 is many at 8.0x3.5x8.05mm with more than the 8.0x3.5x6.0mm, in the frequency range 8.0MHz--200MHz in quartz-crystal resonator UM series.Requiring under above-mentioned operating frequency range and the specification, vertical being vertically mounted on the base seat support of the general employing of AT cut type quartz wafer, this operating frequency range and specification do not satisfy the requirement of communication apparatus to the components and parts microminiaturization; Though if adopt SMD SMD type specification to reduce but its operation frequency performance index does not reach some set point again and cost is higher.Therefore a kind of operation frequency performance index that can satisfy its needs need be designed and developed and microminiaturized requirement of components and parts and lower-cost quartz-crystal resonator can be in communication apparatus, satisfied again.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists in the above-mentioned AT cut type quartz-crystal resonator UM series, designs a kind ofly can satisfy its operation frequency performance index and can satisfy in communication apparatus again that components and parts are microminiaturized to be required and lower-cost a kind of miniature quartz crystal resonator.
The technical scheme that the utility model solves is:
A kind of miniature quartz crystal resonator, comprise package casing 1, pedestal 2, pin 5, reed 6, quartz wafer 3, quartz wafer 3 is arranged in package casing 1, the opening portion of package casing 1 and 2 airtight linking to each other of pedestal, pin 5 links to each other with pedestal 2, it is characterized in that quartz wafer is being installed on the installed surface of reed 6 with horizontal type level of strip, reed 6 is set to mesa structure and is connected with the pin 5 that passes pedestal 2 and fixes on it, and the electrode on the quartz wafer 3 is fixed on the installed surface of reed 6 by conducting resinl.
The quartz wafer 3 that it is characterized in that strip on the installed surface of reed 6 and the vertical range between the pedestal 2 less than 0.8 millimeter, thereby the height of UM type crystal is reduced to below 3.5 millimeters by minimum 6 millimeters.
Still to be strip quartz plate 3 change the silver level into by the vertical installation of UM type wafer to its feature installs.
Its feature still be pin 5 can be lead type also can be SMD.
Remedied the defective of the technical specification of package dimension in the 1.8-3.5mm scope in quartz-crystal resonator UM series by above technological improvement, alternative package dimension is at 8x4.5x1.7mm (SMD) and 7x5x1mm, the properties of product of 6x3.5x1mm (SMD) specification; Its cost of comparing with the quartz-crystal resonator components and parts of SMD (SMD) of constructed parameter has reduced by 50%, the production domesticization of raw material round Realization; Its product can be widely used in miniature communication apparatus such as mobile phone, miniature walkie-talkie, in the equipment such as micro memory such as USB flash disk, MP3, bluetooth earphone.
