Abstract
The utility model provides a working electrode capable of preventing soldering tin from adhering to an electrode and belongs to the technical field of the piezoelectric ceramic resonators. The working electrode comprises an atomized transduction sheet and an energy trap electrode and is characterized in that the circular energy trap electrode is disposed on one surface of the atomized transduction sheet. A protruding sheet which extends outwards is disposed on the outer edge of the energy trap electrode. Isolation strip areas are respectively arranged on the rear portion of the protruding sheet. A welding strip area which can stick to the soldering pin is arranged on the front portion of the protruding sheet. The welding strip area is electrically connected with the protruding sheet extending out of the outer edge of the energy trap electrode through a conductive wire strop with the width of 1.0-2.0 millimeters. As the isolation strip areas are arranged between the welding strip area and the protruding sheet extending out of the outer edge of the energy trap electrode, and the welding strip area is electrically connected with the protruding sheet through the conductive wire strop with the width of 1.0-2.0 millimeters. Fundamentally, the soldering tin is prevented from adhering to the electrode, and consequently resonance characteristics of the transduction sheet cannot be affected.
Description
Technical field
the utility model is a kind of work electrode that is used for ultrasonic atomization transducing sheet, is a kind of work electrode of avoiding the tin top electrode specifically, belongs to the piezoelectric ceramics resonator technical field.
Background technology
ultrasonic atomizatio transducing sheet is one type of piezoelectric energy-conversion device that is used for atomizing humidifying performance, and its essence is a powerful piezoelectric ceramics resonator.Piezoelectric ceramics resonator is made up of the exciting electrode of piezoelectric ceramic substrate and two sides coated conductor material jointly, and according to the difference of use occasion, piezoelectric ceramics resonator can be selected the different working pattern, like face profile shear mode and flexible degree of the shaking pattern of thickness etc.The operating frequency commonly used of ultrasonic atomizatio transducing sheet generally more than 1700KHz, needs to adopt the thickness extension vibration mode formula.Atomizing transducing sheet has very big equivalent inductance; It is again the operating load of atomizer except that the operating frequency of decision-making circuit simultaneously, in order to guarantee concentrating of energy output to greatest extent; The electrode design of atomizing transducing sheet has adopted the mode of ability trap electrode; The pattern of two sides coated conductor material differs bigger, and one side adopts the full electrode pattern with substrate overall size basically identical, and one side adopts the small electrode pattern of size much smaller than sizes of substrate.In addition, in order to guarantee that with being electrically connected of external circuit the part zone of small electrode can be used as welding zone.The traditional electrode pattern of atomizing transducing sheet generally is circle; Having got the sub-fraction zone at the edge of circle then uses as welding zone; Demonstration through a large amount of practices; There is certain drawback in this method, and the solder joint of welding zone has influenced the resonance characteristic of transducing sheet to a great extent, causes the operating characteristic variation.
Summary of the invention
The purpose of the utility model is: a kind of work electrode of avoiding the tin top electrode is provided,
make it both guarantee the needed ability of transducing sheet work trap electrode, have avoided the influence of welding zone to transducing sheet resonance characteristic again.
are for solving its technical problem; The technical scheme that the utility model adopts is: the work electrode of the tin the avoided top electrode of designing; Comprise atomize transducing sheet and ability trap electrode, its feature is: 1. the one side at atomizing transducing sheet is provided with circular ability trap electrode, on the outer edge of this ability trap electrode, is provided with outward extending lug; Respectively be provided with a not isolation zone of weldbonding tin at the rear portion of lug, be provided with the welding zone of an ability weldbonding tin in the front portion of lug; Between weld zone and the lug that draws in the outside, be that the conductive line of 1.0-2.0mm is communicated with through a width; 2. the width of wherein isolating zone is 0.30-0.50mm.
the utility model has the advantages that: because of the isolation strip that is provided with certain width between the lug of drawing of weld zone and ability trap electrode; And be that the conductive line of 1.0-2.0mm is communicated with through a width; Fundamentally avoided the tin top electrode in the welding process, can not influence the resonance characteristic of transducing sheet like this because of the tin top electrode.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the structural representation vertical view of the utility model;
are conductive line 4., and 5. atomizing transducing sheet is 6. isolated zone.
Embodiment
With reference to accompanying drawing: the one side of original atomizing transducing sheet 5 be provided with circular can trap electrode 1; On the outer edge of this ability trap electrode, be provided with outward extending lug 2; Respectively be provided with a not isolation zone 6 of weldbonding tin at the rear portion of lug, be provided with the welding zone 3 of an ability weldbonding tin in the front portion of lug; Between weld zone and the lug that draws in the outside, be that the conductive line 4 of 1.0-2.0mm is communicated with through a width; The width of wherein isolating zone 6 is 0.30-0.50mm.During making, the half tone that the first step is used according to design producing silk screen printing shown in Figure 1; Second step adopted silk-screen printing technique that above-mentioned electrode pattern is printed onto on the piezoelectric substrate, and burning infiltration goes out electrode pattern under the high temperature of 700-850 degree; The 3rd step adopted the mode of manual welding to accomplish welding in the position, weld zone, confirmed the improvement situation of isolation strip to the tin top electrode.
