Specifically, I praised the person and waited for the following research: the structure of the prior art is accommodated by the outer casing 3 200947776 from the upper side, and the lower side is lower than the lower side. [Invention] The production of the present invention Improvement. The piezoelectric transformer of the present invention occupies a mounting area electrical transformer, according to the present invention: the first piezoelectric state is mounted on the second piezoelectric body and is mounted on the first piezoelectric device and mounted on the electric one piezoelectric transformer After the mounting of the plurality of examples of the present invention, the piezoelectric piezoelectric transformer in the first piezoelectric transformer is mounted, and the size of the upper casing is set longer. Secondly, the installation area is slightly expanded. One of the objectives ^The further reduction of the mounting area of the horse or the inventor of the inventor, at least two sections of the needle street are installed in the range of the piezoelectric transformer in the lower stage (in the ampoule area) ) The purpose of the above-mentioned second stage is pressed into the above. A mode of providing a piezoelectric transformer device that includes a transformer in a first housing that houses a first piezoelectric body; and a transformer that houses the second piezoelectric body in the second housing, and In the state above the piezoelectric transformer, the mounting area projected on the circuit board via the first piezoelectric change substrate is in the range of the mounting area in the circuit board. In the piezoelectric transformer device of one aspect, even if the structure is such as two or more piezoelectric transformers, the mounting area or the mounting area of the second piezoelectric transformer in the second stage is not large in the mounting area or the mounting area of the transformer. . That is, the press-fit area is accommodated in one portion. Therefore, the mounting area of the piezoelectric transformer transformer restaurant is often minimized, but the installation of a high-density piezoelectric transformer such as 4 200947776 is realized. Preferably, the first and second housings have a defined shape that is common to each other. The shape is common between the plurality of piezoelectric transformers, so the mounting area of the piezoelectric transformer on the circuit substrate or the mounting area or the mounting area of the first piezoelectric transformer in the mounting substrate The state overlaps each other. Moreover, 'because the shape of the casing is normalized for all the piezoelectric transformers, even if the position of the casing is laminated, even if the sections are overlapped, the mounting area on the circuit board will not be more than one part of the casing. expand. The same is true for the case where a piezoelectric transformer is laminated after the third stage. Further, since it is not necessary to make the casing common to each other between the plurality of piezoelectric transformers, it is possible to reduce the manufacturing cost as compared with the case of individual design and manufacture. In the present invention, it is preferable that the electrical connection of a plurality of piezoelectric transformers is carried out by a configuration. That is, the first and second housings each have a projection formed by the side. © The first piezoelectric transformer has a first conductive member that penetrates the protruding portion of the first casing and extends in the up and down direction. The lower end portion of the first conductive member is formed by a first terminal connected to a wiring pattern of the circuit board. The upper end portion of the first conductive member is bent along the protruding portion and formed as a first connection to the second piezoelectric transformer. Passing the protrusion of the second casing and extending the lower end portion of the first conductive member is the second domain and the domain are common. The housing of the point is protruded from the top surface of the mounting portion. The second piezoelectric transformer has a second conductive member in a continuous direction. Up and down 200947776 The bottom surface of the protruding portion is bent and formed as a second mounting terminal connected to the terminal for connection of the first piezoelectric transformer. In a state where the second piezoelectric transformer is mounted on the first piezoelectric transformer, the second mounting terminal and the first connecting terminal are engaged with each other. As described above, between the first piezoelectric transformer and the second piezoelectric transformer, the first connection terminal and the second mounting terminal are each bent along the corresponding top surface and bottom surface. Therefore, when the second piezoelectric transformer is mounted on the first piezoelectric transformer, the first connection terminal and the second mounting terminal overlap each other in parallel in the same Φ plane. As a result, the joining operation of the first connection terminal and the second mounting terminal, for example, a soldering operation or a heat-curing conductive paste coating operation can be easily performed. In one aspect of the present invention, the first connection terminal and the second mounting terminal may be disposed by the side surfaces of the first and second housings, and the first connection may be performed. A space for joining work is ensured between the terminal and the second mounting terminal.

The exposure is stabilized by ^ ^ ^ ^ , and the bonding workability between the first connection terminal and the second mounting terminal is improved. 6 200947776 More specific surface protrudes from the bottom surface of the upper body, the first piezoelectrically deformed second housing, in this case, the guiding portion - due to the positioning and the second mounting, the workability and the first and second It is formed on the mounting terminal and the secondary side electrode. One of the mounting end electrodes 'the other electric body is not connected, and one of the two of the protruding portion electric parts is used for the second mounting at this time. The guiding portion is the first housing. square. Further, it is a form in which the protruding portion is at least from the lower side. According to this, in the state where the second piezoelectric transformer is mounted on the ejector, the housing is guided by the guide portion by the projection. The second housing is positioned while the second piezoelectric transformer is loaded with the protruding portion while the first piezoelectric transformer is being pressed. Further, since the guide portion also contacts the protruding portion, the second piezoelectric transformer is not improved at the time of the joining operation of the first connection terminal. In one aspect of the invention, it is preferred that the projections and the conductive body cutters are each provided with four locations. In two of the protruding portions of the first portion of the first housing, the first connection terminals are respectively connected to the other two of the two protruding portions of the piezoelectric body, one of the two The first connection terminal and the first connection terminal connected to the piezoelectric body are connected to the first connection terminal and the first connection terminal 〇 in the second piezoelectric transformer for two places formed in the second housing The second mounting terminals are respectively connected to the primary side electrodes. The other second mounting terminals among the four protruding portions are not connected to the piezoelectric body, and the other terminal thereof is connected to the secondary side electrode of the piezoelectric body. Mounting the top two shells of the second piezoelectric transformer on the first piezoelectric transformer is carried on the inducer, and the terminal will be biased in the first side of the device and the four sides of the pressurization Shape 7 200947776 ": the first mounting terminal for the second piezoelectric transformer connected to the secondary side electrode of the piezoelectric body and the first one for the first piezoelectric transformer not connected to the piezoelectric body The connection terminal is joined. Further, the second: the electric transformer 'and the first-f mount terminal that is not connected to the secondary side electrode of the piezoelectric body and the second-stage connection to the piezoelectric body for the first-piezoelectric transformer The first connection of one of the side electrodes is joined by the terminal. In one aspect of the present invention, how to install the plurality of piezoelectric transformers and how to perform the electrical connection of the piezoelectric transformers that are not directly mounted on the circuit board becomes In the prior art, the piezoelectric transformer of the upper side is formed with an arm-shaped terminal branch portion on the side surface of the casing, and a secondary side terminal is disposed at the lower portion thereof. Second time The configuration in which the terminal is directly mounted on the circuit board is employed. However, in this case, 'the piezoelectric transformer on the upper side is separated from the structure of the inter-piezoelectric transformer on the lower side, and the piezoelectrics are respectively required to be respectively on the lower side and the upper side. The transformer is mounted on the circuit board 'only in this way man-hours. This point 'in a preferred aspect of the invention, the shape of the casing is common between a plurality of piezoelectric transformers It is basically not feasible to directly mount the second piezoelectric transformer on the circuit substrate, so a structure in which the terminal of the second piezoelectric transformer is joined to the terminal of the first piezoelectric transformer is used. Accordingly, the piezoelectric transformer device is mounted. When the whole circuit board is used, the terminal used is only the terminal of the first piezoelectric transformer, so that only the working time is reduced, and 'by pre-bonding each other between the first piezoelectric transformer and the second piezoelectric transformer The terminal, the overall structure of the piezoelectric transformer device becomes sturdy, and the stability during installation work can be improved. 8 200947776 Moreover, the first and the flute - the Gyula gas has a Depending on the position of the confirmation, it is preferred that the indication direction is better. As in the above * at Hjfc η ι , the electric current has the primary side electrode and the secondary side electrode, which need to be correctly aligned. :& Temple 1 - The position of the human side electrode and the secondary side electrode, two piezoelectric transformers are assembled, and the α θ is a device, but the piezoelectric body is a structure that is housed in the casing, so assembly is performed.

As shown in Fig. 3 and Fig. 3, the guide rails 16 welded to the secondary side electrode 12b are welded in a state of being bundled on the upper end portion 20d of one of the conductive members 2''. A, 鲆 鲆 。. For the secondary side electrode 丨2b, the conductive wire 16 is welded to the mounting end 9 cores I, and the spreading terminal 20c may be used. Further, the piezoelectric transformer 100 of the lower stage is also a so-called empty terminal in which the conductive member 22 of the other side of the square anvil and the piezoelectric ceramic 12 are electrically connected. Here, as shown in Figure 〖 and Figure 2 thousand. The next section of the electric transformers] in the upper section of the wish to change the _ opposite to the surface. That is, if the upper β conductive members 20 and 22 are disposed on both sides, the two electrification inks _ and 2 are overlapped in the square of the casing u. . The conductive member of the segment is on the surface: the conductive member 22 of the upper segment is located on the side of the lower member (1) of the lower member (1). In the side surface, the conductive structure of the upper stage [improvement of assembly workability] Next, the above-mentioned (4) assembly operation of the piezoelectric transformer 20 0 for pressing the thunder is described in the above paragraph. Fig. 5 is a front view of the entire piezoelectric transformer device. Further, in Fig. 5, a two-person side electrode j 2b is illustrated as Fig. 4 . The direction of the face. 5 to [guide portion] 2, the casing 14 is integrally formed with a projection guide eud in advance at four places on the top surface thereof. For example, the guide portion 14d is located above the projections ua at the same plane as the respective side faces of the casing 14, and protrudes upward from the top surface of the casing U to a certain height. Further, in the illustrated example, the length of the longitudinal direction guiding portion 14d of the casing 14 is equal to the width of the protruding portion 14a, but is not particularly limited thereto. On the other hand, the lower end portion of each of the projections 14a protrudes from the bottom surface of the casing 14 only to a certain extent below. Therefore, as shown in Fig. 2 and Fig. 5, if the piezoelectric transformer m〇0 of the upper stage is placed above the piezoelectric transformer 200947776 1 00 of the lower stage, the lower end portion of the protruding portion i4a of the upper stage is guided along the lower stage. The sides of the lead portions 14d are guided, and the casings 4 are positioned relative to each other. Further, at this time, the connection terminals 18b, 18b, 2B, 22b and the mounting terminals Me, 18c, 22c, and 20c are vertically overlapped with each other as described above, and the piezoelectric transformer 2 of the upper stage is placed in the lower stage. Above the piezoelectric transformer 100, this time becomes the state in which the lower end portion of the protruding portion 14a contacts the respective guiding portions 14d, and the piezoelectric transformer of the upper stage can be stably placed. Thereby, the joining operation of the connection terminals 18b, 18b, 2()b, 22b and the mounting terminals i8c, 18c, 22c, and 20c, for example, welding or the application of the thermosetting conductive paste can be effectively performed. [Space for Bonding Work] Further, as shown in FIGS. 3 and 4, the respective conductive members 18, 18, 20, and 22 are disposed at positions spaced apart from the both side faces of the casing 14 by a certain degree. This point is also the same for the piezoelectric transformer 100 of the lower stage. In this way, since the space for the bonding work is ensured between the side surfaces of the casing 14 and the connection terminals 18b, 18b, 20b, and 22b and the mounting terminals 18c, 18c, 22c, and 20c, the piezoelectric transformer device is used. The joining work of the connection terminals 18b, 18b, 20b, and 22b and the mounting terminals 18c, 18c, 22c, and 20c can be performed extremely easily in the manufacturing process. [Electrical connection of the piezoelectric transformer of the upper stage] In the piezoelectric transformer 200 of the upper stage, the primary side electrodes 1 2a of the two different polarities are connected to the connection terminals of the piezoelectric transformer 100 of the lower stage through the mounting terminals 18c, respectively. 18b. At this time, by making the polarities of the primary side electrodes 1 2a coincide with each other in the upper and lower stages, the input sides of the two voltages 16 200947776 electric transformers 100 and 200 can be formed side by side. Further, as shown in FIG. 5, the piezoelectric transformer 200 of the upper stage is connected to the connection terminal 22b of the lower stage by the connection terminal 20c which is the left side in FIG. 5 through the secondary side electrode 1 2b, and becomes the lower stage. The mounting terminal 22a of the empty terminal connects the mounting terminal 20c to the circuit board. Accordingly, the piezoelectric transformer 200 of the upper stage can be easily mounted on the circuit board without using a particularly long terminal. [Indication of Direction] 〇 Further, a marker part 14e is integrally formed on the housing 14 at one end face, for example, viewed in the longitudinal direction. The indicator portion i4e is a symbol for aligning the directions of the electric transformers 100, 200 when they are assembled. Since the indicator portion 14e is formed to protrude from a position that can be easily visually recognized from the outside, for example, the assembly operator may assemble the piezoelectric transformers 100 and 200 of the upper and lower stages while aligning the direction of the indicator portion 14e. According to this, a simple operation error, for example, the failure of joining the primary side electrode 1 2a and the secondary side electrode i 2b is reliably prevented. Since the piezoelectric transformer device according to the above-described embodiment is common in the shape of the casing 14 between the plurality of piezoelectric transformers 100 and 200, the following advantages are obtained: (1) Design and manufacturing process of the casing 14. For example, molds and the like are common, but the man-hours spent on designing and manufacturing are suppressed, and the reduction in manufacturing cost is realized. (2) Even if the overlapping piezoelectric 辔 gg 〇 „ „ ^ transformer is 100, 200 into a plurality of sections constitutes a piezoelectric transformer device, the overall area of the Anlu and the combination of the secret will not increase Up to one part is pressed at a higher density with the 200947776 pressors 100, 200. Therefore, the circuit board is piezoelectrically mounted. Moreover, the improvement of the casing 14 is made, for example, the protrusion 1 4 a or In the work space or the like, the workability of assembly work or welding of the lightning-damage transformers 100 and 200 is improved, and the production efficiency of the piezoelectric anti-pressure device is greatly improved. The present invention is not limited to μ. The above-described embodiment can be implemented by various modifications. For example, a piezoelectric ceramic ridge! The shape of the silicon tile is not limited to those shown in the drawings, and may be other shapes. Further, the shape of the portion _ ^ the body 14 may be combined with the piezoelectric shape. The outer shape of the ceramic D 12 is suitably deformed. In one embodiment, the heat is used in the case of using the common shape of the red and the shape of the housing 14 between the piezoelectric transformers 100 and 200 in the upper and lower stages. The housing can also be, for example, for the piezoelectric deformation of the lower section The case 1 4 having the same shape as that of the VL is used, and the mounting area or the mounting area when the piezoelectric transformer 2 上 of the upper stage is projected on the circuit board may be smaller than the case 14 . Even in this case, the mounting area of the piezoelectric transformer device in the circuit board is set by the piezoelectric transformer 2 of the upper stage and the mounting area of the piezoelectric transformer 丨0〇 of the lower stage or the range of the mounting area. In the first embodiment, the piezoelectric transformer device has three or more piezoelectric transformers. In one embodiment, the piezoelectric transformer device may have three or more piezoelectric transformers. Although the piezoelectric transformers 100 and 200 on the upper and lower sides insulate the secondary side electrodes 12b from each other, the secondary side electrodes 12b may be connected. In one embodiment, the identification portion 14e is a case of a projection shape of 200947776. It may also be in the shape of a depression. Moreover, the finger-indicating portion in the direction may be marked on the outer surface of the casing 14 by printing or laser printing or the like.
