Abstract
The utility model discloses a quartz resonator which comprises a substrate, wherein an upper groove for pasting a quartz crystal wafer and a lower groove for pasting a thermistor are respectively formed on the front side and back side of the substrate and are not communicated with each other; an inner electrode connected with a crystal wafer pin is arranged in the upper groove and positioned at two opposite corners of the upper groove along the diagonal line of the upper groove; a supporting part is arranged at each of another two opposite corners of the upper groove; a middle electrode connected with a thermistor pin is arranged in the lower groove; and the long edge of the lower groove is perpendicular to that of the upper groove. The lower groove is rotated around a certain angle on a plane in which the lower groove is formed; the long edge of the lower groove is perpendicular to that of the upper groove; and the middle electrode is arranged along the direction of the long edge of the lower groove, so that the middle electrode in the lower groove is staggered from the inner electrode in the upper groove, and interference is avoided.
Description
Technical field
The utility model relates to quartz resonator, relates in particular to a kind of SMD quartz resonator.
Background technology
SMD quartz resonator core position is exactly piezolectric crystal unit (quartz wafer) and temperature-sensing element (device) (thermistor), and mounting base is as one of of paramount importance component parts wherein, and manufacturing and designing of it is just particularly important.
Have upper groove that mounts quartz wafer and the low groove that mounts thermistor in the substrate of existing SMD quartz resonator; Upper groove, low groove are all opened the front at substrate; Low groove below upper groove and upper and lower groove be connected, be provided with the interior electrode that links to each other in order to the wafer pin in a side of upper groove, be provided with the support portion at opposite side; In low groove, be provided with the middle electrode that links to each other in order to thermistor pin electrode, the long limit of upper groove is parallel to the long limit of low groove; The problem that exists has: the mutual pollution that when overall package, can produce wafer and thermistor; And; In use, find resonator job insecurity sometimes, trace it to its cause; Be because upper and lower groove is provided with along same direction, so quartz wafer and thermistor can produce each other and resonate and interference.
Summary of the invention
The utility model is to the deficiency that exists in the above-mentioned prior art, provide a kind of can when encapsulation, avoid producing between wafer and the thermistor pollute, and reduce between quartz wafer and the thermistor quartz resonator of mutual interference mutually in use.
The technical scheme of the utility model is achieved in that
Quartz resonator includes substrate, is provided with the upper groove that is used to mount quartz wafer in the front of substrate; Be provided with the low groove that is used to mount thermistor at the back side of substrate, upper groove and low groove are not connected, and the shape of upper groove and low groove is rectangle; The residing plane parallel of upper groove is in the residing plane of low groove; In upper groove, be provided with the interior electrode of connecting wafer pin, described interior electrode is made up of first positive electrode, first negative electrode, and described first positive and negative electrode is arranged on the place, two diagonal angles of upper groove along the upper groove diagonal; Two other place, diagonal angle at upper groove respectively is provided with a support portion; In low groove, be provided with the middle electrode that connects the thermistor pin, described middle electrode is made up of second positive electrode, second negative electrode, and the long limit of said low groove is perpendicular to the long limit of upper groove; Middle electrode is the long side direction setting along low groove, and low groove is arranged on the center of substrate back.
Adopted the beneficial effect of the utility model of technique scheme to be:
The upper and lower groove of the utility model is opened the front and back at substrate respectively, avoids wafer and thermistor to pollute possible generation between the two; And the utility model has reversed certain angle with low groove on its residing plane; Make the top of the long limit of low groove perpendicular to upper groove; And the middle electrode in the low groove is the long side direction setting along low groove, and the interior electrode of upper groove is the diagonal setting along upper groove, staggers thereby make the interior electrode of middle electrode and the upper groove of low groove that direction is set; Prevent to produce resonance and interference; Through practical proof, adopted the structure of the utility model, the quartz resonator job stability had had raising more in the past.
