Abstract
The utility model provides a miniature ultrasonic sensor and relates to the electromechanic sense technic. The utility model changes the volume and thickness of the case appropriately, chooses definite materials and unique structure, improves the sensitivity-frequency characteristic electric wire and makes frequency band wider. The utility model has the advantages of small size, light weight and easy fabrication. The utility model meets various requirements of sensor block within the range of 20 khz-50 khz in the industry, the military, the civil, etc.
Description
A kind of miniature ultrasonic wave sensor relates to the pickoff technology.
The miniature ultrasonic wave sensor is being brought into play more and more important effect in different fields at present, it is narrow that but normally used this series products exists frequency band, the Circuit Matching poor stability, volume is big, and quality heavily waits shortcoming, in 20KH～50KH frequency range, problem is particularly outstanding, the high 12mm of such transducer of the U.S. for example, the thick 2.5～33.5mm of housing, heavy 12.5g has limited its production and the application in every field greatly.
It is little that the utility model aims to provide a kind of volume, light weight, and structure is special, and can improve the miniature ultrasonic wave sensor of sensitivity and broadening frequency characteristic scope.
In using according to reality to the different requirements of the frequency characteristic scope of transducer, the size and the thickness of appropriate change ultrasonic sensor housing, broadening the frequency characteristic scope of transducer, enable to satisfy the needs that for example in 20KH～50KH scope, use in particular frequency range, select certain nickel plating or zinc-plated for use, its housing of material such as silver-plated, and do to divide other to be connected with housing and leading foot piezoelectric ceramic vibrator, remedied because the problem that the sensitivity that smaller volume is brought descends, it is big that the change of housing size and thickness has meanwhile solved the existing volume of normally used transducer again, and quality heavily waits problem.
The utility model can be widely used in industry, military affairs, the field such as civilian, satisfies in 20KH～50KH frequency range the various requirement to transducer.
Shown in Figure 1 is structural representation of the present utility model.
Shown in Figure 2 is sensitivity one frequency characteristic figure of the present utility model.
Here provide an embodiment of the present utility model.
At one end the inner top of the circular punching out hat shell of the flat-top of opening (1) is pasted a slice piezoelectric ceramic vibrator (2), with elastic adhesive (5) shell is fixed on the bottom (4) of two leading foots (6) (7) at its edge of opening, high h3.8 ± the 1mm of housing (1), the thickness of housing (1) and piezoelectric ceramic vibrator (2) is 0.3 ± 0.1mm, housing diameter D is 11 ± 2mm, the only heavy 1g of quality, be suitable for resonance frequency 20KH～50KH, draw a lead-in wire (3) and be connected with the lateral surface of piezoelectric ceramic vibrator (2) at the place, the inner of leading foot (6), and draw a lead-in wire (8) and directly is connected with housing (1) medial surface of transducer at the place, the inner of leading foot (7).
Sensor housing (1) can use the nickel-clad iron leather material to make, and materials such as also available tin plate or silver-plated iron sheet are made.
Sensor housing (1) can be made into the circular punching out cap of the flat-top shape of an end opening, also can be made into other shapes.
Claims (2)
1, a kind of miniature ultrasonic wave sensor, relate to the pickoff technology, the utility model is by housing (1), piezoelectric ceramic vibrator (2), bottom (4), lead-in wire (3) (8), elastic adhesive (5), leading foot (6) (7) is formed, it is characterized in that: the volume that dwindles housing, the thickness of attenuate housing, make the high h3.8 ± 1.0mm of housing (1), the thickness of housing (1) and piezoelectric ceramic vibrator (2) is 0.3 ± 0.1mm, housing diameter D is 11 ± 2mm, lead-in wire (3) connects the inner of leading foot (6) and the lateral surface of piezoelectric ceramic vibrator (2), lead-in wire (8) connects the inner of leading foot (7) and the inboard of housing (1), and housing (1) becomes with the nickel-clad iron leather.
2, transducer according to claim 1 is characterized in that available galvanized iron sheet of housing (1) or silver-plated iron sheet make.
