Abstract
The utility model relates to a piezoelectric ring of an ultrasonic transducer, which comprises a piezoelectric ring body. The utility model is characterized in that the inner ring surface and the outer ring surface of the piezoelectric ring body are respectively fixed with a covering layer which is composed of a copper ring and an aluminium ring, wherein, the copper ring and the aluminium ring which are positioned on the same ring surface are arranged in parallel and are closely contacted. The piezoelectric ring of an ultrasonic transducer of the utility model can be reliably connected with a lead wire, can enhance the performance of the ultrasonic transducer, and can extend the service life of the transducer.
Description
Technical field
The utility model relates to a kind of parts of ultrasonic transducer, especially a kind of ultrasonic transducer piezoelectric ring.
Background technology
Existing a kind of ultrasonic transducer piezoelectric ring mainly is made of the piezoelectric ring ring body, outer surface at the piezoelectric ring ring body has one deck silver coating, when being connected, normally directly inside and outside the two poles of the earth lead-in wire directly is welded on the silver coating of piezoelectric ring ring body, then outsourcing epoxy resin with external circuit.When big or working time of too high or operating current is long when the working media temperature of transducer, epoxy resin is aging gradually, splits and comes off under the high vibration of piezoelectric ring, afterwards, the silver layer at lead solder-joint place is also just tired gradually and come off, and causes the damage of transducer.Therefore, above-mentioned existing product exists defective.
The utility model content
The purpose of this utility model provides the long ultrasonic transducer piezoelectric ring of a kind of working life.
Ultrasonic transducer piezoelectric ring of the present utility model has the piezoelectric ring ring body, it is characterized in that being set with the clad that is made of a copper ring and an aluminium ring respectively at the inner ring surface and the outer ring surface of piezoelectric ring ring body, the copper ring that is positioned at same anchor ring is set up in parallel and closely contacts with the aluminium ring.In the utility model, can be by mode such as compacting, copper ring and aluminium ring be fixed on the piezoelectric ring ring body and constitute above-mentioned clad.When joining, inside and outside the two poles of the earth lead-in wire can be welded on respectively on the copper ring of inside and outside anchor ring with external circuit.Like this, because lead-in wire and solder joint place are with a kind of metal, promptly being metallic copper, is easy and firm in welding.Because copper, the endurance ratio of aluminium ring when high temperature, high power work is much larger than epoxy resin, the corresponding performance that can improve ultrasonic transducer prolongs service life of transducer.Simultaneously, the copper ring of same anchor ring is set up in parallel and closely contacts with the aluminium ring, being equivalent to the two conduction connects, increased conductive area thus, reduced contact impedance, and give the piezoelectric ring ring body and go up certain even prestressing force at sound wave transmit direction (ring body radially), this also can improve the vibration state of piezoelectric ring, prolongs the service life of piezoelectric ring.In addition, the velocity of sound of copper, these two kinds of materials of aluminium is very high, and density is less, and its characteristic acoustic impedance is very little, can play good transaudient effect, and the piezoelectric ring clad that is made of these two kinds of materials can improve the efficient of ultrasonic transducer.In the utility model, the conductance of the copper material of formation copper ring is greater than aluminium, and be easy to and wire bonds, and the acoustic characteristic impedance of the aluminium of formation aluminium ring is less than copper material, therefore, on the same anchor ring (inner ring surface or outer ring surface) of ring body, be set up in parallel copper ring and aluminium ring simultaneously, will help bringing into play speciality separately, further improve the performance of product.Because being provided with of copper ring mainly is the welding of being convenient to external lead wire,, can allow the exposed area of aluminium ring greater than the exposed area of copper ring therefore concrete when making product of the present utility model.Simultaneously, both can allow the copper ring of the copper ring of outer ring surface and inner ring surface be positioned at the same end of ring body simultaneously, and also can allow the two lay respectively at the two ends of ring body.Certainly, from being convenient to weld and arrange the angle consideration of lead-in wire, be good to adopt a kind of mode in back especially.
Therefore, compared with the aforementioned existing similar products, ultrasonic transducer piezoelectric ring of the present utility model can be connected with lead-in wire reliably, and can improve the performance of ultrasonic transducer, prolongs the service life of transducer, thereby has market prospects preferably.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Description of drawings
Fig. 1 is the structural representation of ultrasonic transducer piezoelectric ring among the embodiment.
The specific embodiment
As shown in Figure 1, ultrasonic transducer piezoelectric ring in the present embodiment has piezoelectric ring ring body 1, it is characterized in that being set with the clad that is made of a copper ring and an aluminium ring respectively at the inner ring surface and the outer ring surface of piezoelectric ring ring body 1, the copper ring that is positioned at same anchor ring is set up in parallel and closely contacts with the aluminium ring.In the present embodiment, the clad of inner ring surface is made of copper ring 2 and aluminium ring 3, and the clad of outer ring surface is made of copper ring 4 and aluminium ring 5; The copper ring 2 of inner ring surface closely contacts with aluminium ring 3, and the copper ring 4 of outer ring surface closely contacts with aluminium ring 5.In addition, in the product that present embodiment provides, the exposed area of the aluminium ring on the same anchor ring is greater than the exposed area of copper ring, and promptly the exposed area of aluminium ring 3 is greater than the exposed area of copper ring 2, and the exposed area of aluminium ring 5 is greater than the exposed area of copper ring 4.Simultaneously, the copper ring 2 that is arranged at the copper ring 4 of outer ring surface and is arranged at inner ring surface lays respectively at the two ends of ring body 1.
Claims (3)
1, a kind of ultrasonic transducer piezoelectric ring, has the piezoelectric ring ring body, it is characterized in that being set with the clad that is made of a copper ring and an aluminium ring respectively at the inner ring surface and the outer ring surface of piezoelectric ring ring body, the copper ring that is positioned at same anchor ring is set up in parallel and closely contacts with the aluminium ring.
