Abstract
The utility model relates to a segmentation electrode type circular ring-shaped vibration generator which is a core part of a tangential polarizing piezoelectric transducer of a splicing ceramics class. The utility model uses an electrode without a metal sandwich to lead out a segmentation electrode, and a conventional method that an electrode is led out by a metal foil sandwich is changed. Thereby, the utility model simplifies assembly technique, enhances yield and improves the effective electromechanical coupling characteristic of products.
Description
The utility model belongs to the structure of piezoelectric ceramic transducer oscillator.
Cutting apart electric pole type annular oscillator, is the core component of amalgamation ceramic-like shear-polarization PZT (piezoelectric transducer).Up to now, cutting apart drawing of electrode about oscillator, all is the mode that adopts the channeling conduct of interlayer electrode structure.As data Harrs.U.S.Pat.No.3,142,032 is described, promptly with metal forming or net, sticks between the electrode of per two amalgamation assemblies splicing, utilizes metal sandwich to solve the way of electrode guiding from gluing the part that extends out in the seam.Do no doubt to make the machine work of amalgamation ceramic component simpler like this, can transmit bigger electric current; Yet but make troubles, can cause the piece level to increase especially, cause obvious increasing, show that the effective electro-mechanical couple factor that makes oscillator descends the vibrating body isolation effect to assembling.The existence of metal sandwich simultaneously increases the difference of the coefficient of expansion between sticking seam level, and consequent thermal stress also can be brought harm to the stable of adhesive strength and oscillator electromechanical properties.Also to point out,, cause the consequence that to save because the insulating effect of glue-line often makes circuit interruption.This is the problem that is easy to occur when contact pressure is little in piecing together sticking process.If use the conductive adhesive agent, can bring the problem of adhesive strength fragility again.
The purpose of this utility model is to overcome the adverse effect that the electrode deriving structure that contains metal sandwich brings for assembly technology, result of use, to simplify assembly technology, improve rate of finished products, stablize electric property, to improve electromechanical coupling characteristics.
The utility model proposes a kind of electrode deriving structure that does not have metal sandwich.It is as the piezoelectric ceramic of piecing together sticking face by the silver electrode layer, carry out local expose and realize.Method is the designated edge place at all bar electrode surfaces, is provided with the chamfering of appropriate depth, thereby is piecing together on the ring, forms one by one by the triangle wire bonds groove that silver layer is arranged and be connected with the sticking face silver layer of assembly.The chamfering degree of depth and gradient are principle can hold bonding wire.Chamfering root requirement garden slips over to be crossed, and to overcome the silver electrode layer breaking phenomena takes place at the crest line place.
Fig. 1 and Fig. 2 are structure charts of the present utility model.
Specific embodiment of the utility model is provided by Fig. 1 and Fig. 2.
(1) Fig. 1 is the situation of big (bar cross-sectional line size is greater than 8 millimeters) of amalgamation piezoelectric element 1.This moment, groove 2 was arranged on the end face of amalgamation oscillator, and lead-in wire distributes by radiation pattern along sticking seam.For or tube wall thicker cause electrode distance uniformity relatively poor situation bigger, can be regulated with electrode distance the chamfering gradient, to avoid making localizing electrode apart from narrow problem takes place because of existing of chamfering because of the amalgamation angle.
When groove 2 was solded into lead, bonding wire 3 was intervally arranged by positive and negative polarity, one side more respectively from groove 2 to drawing separately.Packed layer 4 and cover layer 7 are done with the High Temperature Curing Epoxy Resin System glue that contains 50% glass fibre in weld groove space and of living in along face.7 insulating effects of cover layer, layer thickness control is at 1～2 millimeter.Bonding wire 3 along the circumferential direction welds on insulating barrier 7 respectively by polarity, forms the ring type lead-in wire 5,6 of two parallel connections.After picking out, do solid seal 11 with above-mentioned insulating cement again.If when laying cable socket or cable joint 9, can solid Feng Shiyi piece together plant into.Split collar cylindrical ceramic surface is along the circumferential direction strained with the leached glass fiber epoxy glue and to be twined a thin hoop layer 8 to solve the enhancing of oscillator.
When the amalgamation element is medium size (the bar cross-sectional line is of a size of 5～8 millimeters), when special size restrictions because of the oscillator wall thickness is difficult to arrange simultaneously two circle lead-in wires on an end face, then take positive and negative electrode is drawn from two end faces respectively the way that at one end gathers at last.It and aforesaid difference are that bar all is processed with chamfering at two, are that every each face of only processing simultaneously and make two processing staggers mutually.
(2) Fig. 2 is the situation of amalgamation piezoelectric element 1 less (bar cross-sectional line size is less than 5 millimeters).This moment, groove 2 was arranged on outer round surface, and lead-in wire is pressed the bus pattern along sticking seam and distributed.Can guide an end face into or guide two end faces respectively into along groove bonding wire 3 by polarity.When bonding wire collected in two end faces, then the cover layer 7 of each end face, ring type lead-in wire 5 or 6, solid seal 11 were all handled by (1) situation.When bonding wire collects in an end face, increase an insulating barrier 10, with ring type lead-in wire 5,6 by up and down every gathering into folds, can not put to good use in one plane.For reducing the caused electromechanical properties loss in groove space, need fill with the material with certain elasticity and hot expansibility, its packed layer 4, cover layer 7, insulating barrier 10, solid seal 11 form by the High temp. epoxy resins adhesive curing that contains 50% glass fibre.Split collar cylindrical ceramic surface is along the circumferential direction strained the hoop layer that winding one approaches with the leached glass fiber epoxy glue, can play the effect of guard electrode, has added deviated stress to piecing together circulating application again.
The kind electrode deriving structure, in deep water low-frequency high-power transmitting transducer, acoustic release instruction sound source, ignite acoustic apparatus under water, try out the shallow aspects such as instrument transmitting transducer of cuing open. The result shows the problem that does not take place to reduce the mechanical-electric coupling performance or affect the element polarization, the phenomenon that electricity opens circuit do not occur. Yet, bring great convenience to assembly technology, make electric stability, reliability obtain reinforcement, effective electromechanical coupling characteristics is improved.
