Problems solved by technology

When assembling the transducer, in order to realize the electrical connection of the piezoelectric ceramic sheet group, it is usually necessary to use electrode sheets or soldering sheets. Among them, the patent application number 2013203070825 discloses a piezoelectric ceramic sheet group. The components that constitute the positive electrode of the piezoelectric ceramic sheet group and the components that constitute the negative electrode of the piezoelectric ceramic sheet group that are electrically connected (both have the same structure), although the components that constitute the positive electrode of the piezoelectric ceramic sheet group or the components that constitute the negative electrode of the piezoelectric ceramic sheet group The electrical connection of the piezoelectric ceramic sheet group can be well realized, but the components that constitute the positive electrode of the piezoelectric ceramic sheet group or the components that constitute the negative electrode of the piezoelectric ceramic sheet group are affected by the structure. When connecting the power line (connecting line), It is necessary to weld the power line (connection line) to it with solder by manual welding, and the manual welding method not only cannot guarantee the reliability of the solder joints (higher skill requirements for welding personnel), but also Difficult to automate welding production

Abstract

The invention relates to a soldering lug used in an ultrasonic dental descaler. The soldering lug comprises a first connecting plate, a second connecting plate, a third connecting plate and a fourth connecting plate, wherein the first connecting plate and the second connecting plate are connected with the third connecting plate; the first connecting plate and the second connecting plate are positioned on the same side of the third connecting plate; one end of the fourth connecting plate is connected with the third connecting plate; and the soldering lug is made of a cupronickel material. The ultrasonic dental descaler comprises a piezoelectric ceramic ultrasonic transducer and two soldering lugs, wherein the two soldering lugs sleeve a crystal driving electrode on the piezoelectric ceramic ultrasonic transducer and are used for guiding out the crystal driving electrode; each soldering lug is connected with a connecting wire; and each connecting wire is connected with the corresponding soldering lug in an electric resistance welding mode. The ultrasonic dental descaler has the beneficial effects that automated welding is easy to realize, the diameter of a packing structure of the piezoelectric ceramic ultrasonic transducer can be small, and the problem that ignition of an injection molding layer fails easily in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of dental medical instruments, in particular to a welding sheet and an ultrasonic scaler containing the same. Background technique [0002] There are usually four piezoelectric ceramic wafers in the piezoelectric ceramic sheet group in the ultrasonic transducer used in the existing ultrasonic dental scaler, and the end faces of the same polarity of two adjacent piezoelectric ceramic wafers abut against each other when placed. . When assembling the transducer, in order to realize the electrical connection of the piezoelectric ceramic plate group, it is usually necessary to use an electrode plate or a welding plate. The part that constitutes the positive electrode of the piezoelectric ceramic sheet group and the part that constitutes the negative electrode of the piezoelectric ceramic sheet group (both have the same structure) are electrically connected. The electrical connection of the piezoelectric ceramic sheet gro...
