Embodiment Construction

[0024] The piezoelectric transformer according to the present invention will be described below with reference to the accompanying drawings.

[0025] Figure 3-5 are perspective views of piezoelectric transformers having different structures according to embodiments of the present invention, respectively.

[0026] exist Figure 3-5 The piezoelectric transformer represented by the reference numeral 30 mainly includes: a rectangular parallelepiped piezoelectric element 31, which has two opposite rectangular main surfaces, that is, the first and second surfaces, and four side surfaces, that is, the first and second surfaces. Connected third to sixth faces. The piezoelectric element 30 also includes an input electrode 32 formed on the first of two equal surface portions longitudinally divided on the first surface of the piezoelectric element 31, ie, the left or right surface portion. An output electrode 33 is formed on the second surface portion of the first surface of the piez...

Abstract

The invention discloses a piezoelectric transformer with a node identification pattern, the node identification pattern is used to identify each node for visual identification, and the input electrode and the output electrode are electrically connected to the outside at these nodes, so that it can be welded by manual wire It is easy to electrically connect the input electrode and the output electrode to the outside during the process. And it enables the wire bonding process to be carried out automatically without considering the size of the piezoelectric element. The piezoelectric transformer includes: a piezoelectric element, an input electrode, an output electrode, and a ground electrode, and the electrodes are printed on the piezoelectric element, and the piezoelectric transformer also includes a plurality of node identification patterns surrounding the input electrode, the output electrode, and the ground electrode. The center of the electrode extends radially and is separated from the center of the electrode by a desired radial distance, and each node identification pattern is formed by removing a portion of the electrode corresponding to the node identification pattern.

Description

technical field [0001] The present invention relates to a piezoelectric transformer used as a high-voltage DC generating device, and in particular to a piezoelectric transformer with a node identification pattern, the above-mentioned node identification pattern is used to identify each node for visual identification, and input The electrodes and the output electrodes are electrically connected to the outside, so that the input electrodes and the output electrodes can be easily electrically connected to the outside. Background technique [0002] Currently, the utilization rate of piezoelectric transformers as high-voltage DC generating devices is increasing at a high rate compared with coil transformers because they have the following characteristics compared with those of coil transformers: small size, high efficiency, high electrical insulation, Non-flammable. [0003] Piezoelectric transformers are mainly used in devices such as notebook computers, PDAs (Personal Digital ...
