Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained on the premise of not making creative work, broadly falls into the scope of protection of the invention.
As depicted in figs. 1 and 2, the piezoelectric ceramic ring conductor connecting structure of the ultrasonic transducer that the embodiment of the present invention provides,
Including interior connection ring 2 and outer connection ring 4, described outer connection ring 4 covers and the outside silver layer of piezoelectric ceramic ring 1 of fitting is arranged, institute
State interior connection ring 2 to cover and the inner side silver layer of described piezoelectric ceramic ring 1 of fitting is arranged, and described outer connection ring 4 and interior connection ring
Equal 2 the most at least stretch out a wire bond pad 6, and described wire bond pad 61 is equipped with wire connection hole, and this wire connects knot
Structure, solving that silver layer is caducous inside existing piezoelectric ceramic ring while, makes wire and piezoelectric ceramics in the case of without welding
Ring is stably connected with.
Preferably, as depicted in figs. 1 and 2, interior connection is equipped with two wire bond pad on ring 2 and outer connection ring 4 outside
6, and four wire bond pad 6 stagger setting, when needs multiple transducing unit serial or parallel connection works, facilitate the extraction of wire
And connect.
Further, interior connection ring 2 is open circulus, and the lateral perimeter of this interior connection ring 2 is more than piezoelectric ceramics
The inner side girth of ring, when aliging in the open end of interior connection ring 2, interior connection ring 2 produces prestressing force, makes interior connection ring 2 comprehensive
More it is adjacent to the inner side silver layer of piezoelectric ceramic ring 1, and prevents interior connection ring 2 from coming off from piezoelectric ceramic ring 2, make inner side silver layer obtain
To well protection.
As shown in Figure 3 be under normality in connect ring 2 structure, one of them open end is pressed on another open end, puts
Put in piezoelectric ceramic ring 1, make the alignment of two open end arrange by external force.
Owing to piezoelectric ceramic ring 1 material is more crisp, in order to avoid piezoelectric ceramic ring 1 crushes, consider installation and interior connection
The stability maintenance of ring 2, it is preferable that the lateral perimeter of interior connection ring 2 is 0.2-with the difference of the inner side girth of piezoelectric ceramic ring 1
0.8mm, within the range, the convenient interior ring 2 that connects is installed, and the prestressing force produced enough makes interior connection ring 2 be stably fixed to
The inner side of ceramic ring 1, it is highly preferred that the difference of the inner side girth of the lateral perimeter of interior connection ring and piezoelectric ceramic ring is 0.5mm.
In order to preferably protect the outside silver layer of piezoelectric ceramic ring 1, and do not affect outside silver layer electric conductivity, make outer company
The outside silver layer of T-Ring 4 and piezoelectric ceramic ring 1 is close to arrange, it is preferable that as depicted in figs. 1 and 2, connects the outside of ring 4 outside
It is provided with winding layer 5, it is preferable that winding layer 5 is formed by uniform winding such as indium steel wire, titanium steel silk or wolfram steel silks.
Wherein, the thermal coefficient of expansion of indium steel wire is little, best results, in piezoelectric ceramic ring 1 and outer conducting ring generation thermal expansion
Time, under the effect of indium steel wire, outer conducting ring 4 still can keep the outside silver layer laminating with piezoelectric ceramic ring 1 to arrange.
Preferably, outer connection ring and interior connection ring all use the beryllium-bronze material of high conductivity to make.
Further, also setting up elastic insulated protection ring 3 in the inner side of interior connection ring 2, this elastic insulated protection ring 3 is whole
Connect the inner side of ring 2 in covering, internally connect ring and play the effect supporting protection, prevent interior connection ring from coming off further.
As it is shown in figure 1, for easy for installation and support interior connection ring 2, elastic insulated protection ring 3 is open ring-type knot
Structure, and when mounted, stagger with the interior open end being connected ring 2 setting in the open end of spring insulating protection ring 3, it is preferable that both
Open end couple positioned opposite.
Wherein, the material of elastic insulated protection ring 3 be preferably polyethylene, polypropylene, polystyrene resin, polyimides,
Merlon or politef, have suitable elastic effect more preferable.
When above-mentioned conductor connecting structure is assembled on piezoelectric ceramic ring by the embodiment of the present invention, first by piezoelectric ceramic ring
1 steadily places, and the interior connection ring 2 under normality is placed into the inner side of piezoelectric ceramic ring 1, now, as it is shown on figure 3, described interior company
The open end of T-Ring 2 is staggered overlaying state, and one of them open end does not contacts with the inner side silver layer of piezoelectric ceramic ring 1；
Then power is applied with inner side silver layer to the open end of the interior connection ring 2 not contacted so that it is with described piezoelectric ceramic ring 1
The contact of inner side silver layer, now as it is shown in figure 1, two open ends docking of interior connection ring 2, interior connection ring 2 and piezoelectric ceramic ring 1
Inner side silver layer fit tightly；
Then, by elastic insulated protection ring 3 it is placed on inside described interior connection ring 2, under the effect of elastic force, described elasticity
Insulating protection ring 3 is close to described interior connection ring 2；
Being set in outside described piezoelectric ceramic ring 1 by outer connection ring 4 entirety again, described outer connection ring 4 is adjacent to piezoelectric ceramics
The outside silver layer of ring 1；
The last outside connecting ring 4 outside is uniformly arranged winding layer 5, so that outer conducting layer 4 is close to outside piezoelectric ceramic ring 1
Side silver layer.
It should be noted that each sequence of steps above-mentioned is only more preferably order, its order can the most suitably be adjusted
Whole, outer connection ring 4 such as can be first installed, then winding layer 5 be set, in installing the most successively, connect ring 2 and elastic insulated
Protection ring 3.
In sum, the piezoelectric ceramic ring conductor connecting structure of the ultrasonic transducer that the present invention provides, solving existing pressure
The while that silver layer being caducous inside electroceramics ring, wire is made to be stably connected with piezoelectric ceramic ring in the case of without welding, and
And utilize relatively simple structure to provide protection for silver layer, and utilize prestressing force make interior connection ring and outer connection ring respectively with
The inside and outside silver layer laminating of piezoelectric ceramic ring is arranged so that it is still have good electric conductivity.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent；
And these amendment or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
