New description: [New technical field] This creation is about a kind of transformer, and especially for a multi-function transformer with inductance and voltage transformation function at the same time. [Prior Art] FIG. 1 is a schematic diagram of a conventional transformer. Please refer to the figure. After the first production of the coil type transformer 100 in 1885, it has been more than a century since then. It has been widely used for a long time and has many improvements. Many different types have been designed, but its principle of action. Still consistent. The transformer 100 mainly uses the principle of electric energy and magnetic energy conversion induction to wind two sets of coils 110, 120 on a common core i3, and is connected to a power source (AC) 140. Usually, the coil 110 connected to the end of the power source 14 is referred to as a primary side coil or a primary coil, and the coil 120 connected to the load terminal R is turned into a secondary side coil or a secondary coil. When the coil 11 is connected to the AC power source, the current passing through the coil affects the magnetic flux change of the magnetic core 130, and the coil 120 at the other end generates another alternating current of the same frequency due to the induced electromotive force. Faraday's Law (Faraday, s Law) illustrates the relationship between the induced electromotive force and the magnetic flux and the number of turns in the coil. In an ideal case, the magnetic flux of each turn of the coil is the same, so the induced voltage is proportional to the number of turns of the coil. If the number of turns of the coil 120 (N2) is greater than the number of turns of the coil 11 (N1), the transformer is boosted. A stet-up transformer, and vice versa, a step-down transformer.

The body 212 has a uniform hole 212a extending through a first direction D1, and the partitioning plate 214 is sleeved along the first direction D1 of the body 212. The body 212 is corresponding to a plurality of partitions 216 and a placement space 218. The I-shaped magnetic core 220 is inserted into the placement space 218 of the body 212 along a second direction D2, wherein the first direction D1 is perpendicular to the second direction D2. Each of the E-shaped cores 230 has three ends 232, 234, 236, and the intermediate end 236 is engaged by the two sides of the bobbin 210 into the through holes 212a. The first coil 240 is disposed in a portion of the separation region 216, and the second coils 250a, 250b are disposed in the two separation regions 216, and the second coil 250a is disposed adjacent to one of the first coils 240 in a different separation region 216. . In view of the above, the I-shaped magnetic core 220 may be an integrally formed elongated magnetic core, but may be a combination of a plurality of strip-shaped or block-shaped magnetic cores, which is determined according to actual needs. In addition, the above-mentioned bobbin 210 may further include two L-shaped partitions 219 ′ located outside the partitioning plate 214 and each of the L-shaped partitions 219 has a first portion 219 a and a second portion 219 b perpendicular to each other and the setting An opening 219c of the first portion 219a, wherein the opening 219c is in communication with the through hole 212a.

For example, the partition plate 214 and the L-shaped partition plate 219 are directly formed on the body 212, thereby further saving labor assembly costs. Fig. 4 is a view showing the relative positional relationship between the e-shaped core and the I-shaped core of the multi-function transformer of Fig. 3. As can be seen from FIG. 2, FIG. 3 and FIG. 4, when the multi-function transformer 200 is assembled, the two ends 232, 236 of the e-shaped core 230 located on the opposite outer side are located outside the body 212 and the L-shaped partition 219, and two The ends 232, 234, 236 of the E-shaped magnetic cores 230 face each other and the I-shaped magnetic cores 220 are located opposite the two magnetic cores 230. In addition, since the multi-function transformer 2 is one of the components on the circuit board (not shown), the multi-function transformer 200 may further include the second portion 21 disposed in the L-shaped partition 219 for the purpose of effective functioning. % of the plurality of pins 260, and each of the pins 26A is correspondingly connected to the first coil 24A or the second coils 250a, 250b, and when the multi-function transformer 2 is assembled on the circuit board, the multi-function transformer 200 Its pins are 26 〇 to be electrically connected to the board.

Of course, the stitch 260 can also be disposed on the partition plate 214 according to actual needs. The greater the number of pins 260, the more the assembly stability of the multi-function transformer 2 placed on the circuit board can be increased, and the electrical stability of the multi-function transformer 200 and the board can be improved. °° M404541 Please continue to refer to FIG. 2, FIG. 3 and FIG. 4 simultaneously, since the I-shaped magnetic core 220 is in contact with the ends 232, 234, 236 of the E-shaped magnetic core 230 located on the right side in FIG. 4 to form a magnetic path, and When energized, a transformer variator T is formed together with two adjacent first coils 240 and second coils 250a wound thereon. It should be particularly noted that there is a gap G between the intermediate end 234 of the e-shaped magnetic core 230 on the left side in FIG. 4 and the I-shaped magnetic core 220, so as to be located on the opposite left side of the E-shaped magnetic core 230 and I when energized. The magnetic core 220 and the second coil 250b together form an inductance I. The size of this gap G affects the energy stored in the inductor. Incidentally, the position and the number of the first coils 24A and the second coils 250a and 250b in this embodiment are for illustrative purposes only, in fact, the first coil 240 and the second coils 25〇a, 25〇b The setting position and the number can be changed according to the requirements, and are not limited to the contents of the embodiment, and only one of the first coils 240 and the second coil 250a are disposed adjacent to each other to provide the function of the transformer, and the other The two coils 250b are separately provided and matched with the gap G between the magnets 230 and the I-shaped cores 220 to achieve the purpose of providing the inductance work =. As can be seen from the above, the multi-function transformer 200 of the present embodiment integrates the inductor I and the transformer T by the design of the structure, so that the functions of the transformer and the inductor can be simultaneously provided. In addition, the use of the second coil 250b can be omitted without requiring an inductive function. In the present embodiment, the second coil 250a and the second coil 25〇b are represented by different numbers to indicate that the two=turns are not completely the same, for example, the number of coils of the second coil 25〇a and the second coil 25% is different or Is the wire diameter not _. Alternatively, the two sets of second coils 25, such as 9 M404541 250b, may also have the same number of coils and wire diameters to treat the two sets of second coils 250a, 250b as one coil group 'one as the transformer T once.
