FIELD OF THE INVENTION
The invention relates to a transformer structure, in particular to a transformer structure which meets the isolation requirement without threading a sleeve during winding.
BACKGROUND OF THE INVENTION
At present, the primary side or the secondary side of the transformer is not only implemented by a single winding but by a plurality of windings, so that when the transformer with the plurality of windings on a single side is used for leading out wires, an isolation sleeve is sleeved at a tail end of each winding to avoid wrong contact between the windings.
However, this method leads to the fact that in the development of transformers, the isolation sleeves need to be manually installed at the ends of each winding and cannot be implemented mechanically and automatically.
Furthermore, although CN 203760282U proposes a technical solution aiming at solving the afore mentioned problems, the wire frame disclosed in the patent is only partially isolated from the wire outlet part, and cannot be used in the case where a plurality of sub-windings connected in series exist in a single-sided winding.
In addition to the foregoing, there are other patents disclosing structures for isolating wires, such as those disclosed in TW M505046 and CN 101908411B, which do not address a specific isolation solution in the case of a plurality of sub-windings connected in series in a single-sided winding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The terms “first”, “second”, and the like, when used in connection with elements of the invention, are intended to distinguish one structure from another and are not intended to be limiting in any way whatsoever. The detailed description and technical contents of the present invention will now be described with reference to the drawings as follows:
Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the present invention provides a transformer 100 for performing winding without matching sleeve, which may be vertical or horizontal rather than limit to the horizontal as shown in the drawing of the present invention. The transformer 100 includes a transformer wire frame 10, an iron core 20 mounted on the transformer wire frame 10, a first winding unit 30, and a second winding unit 40. The transformer wire frame 10 comprises a winding part 11, a first wire outlet part 12 connected to one side of the winding part 11, and a second wire outlet part 13 connected to the other side of the winding part 11 which is not provided with the first wire outlet part 12. Further, the winding part 11 includes a substantially tubular structure so as to provide a portion of the iron core 20 therein. The winding part 11 includes a first baffle 111 close to the second wire outlet part 13 and at least a second baffle 112 distinguishing a winding area of the first winding unit 30 and the second winding unit 40. The first baffle 111 is different from the second baffle 112, the second baffle 112 is designed to surround the winding part 11, the first baffle 111 is only provided on a portion of the winding part 11 without surrounding the winding part 11. Further, the second wire outlet part 13 includes a first inclined surface 131 facing the winding part 11, a first partition plate 132 provided on the first inclined surface 131, and a first block 134 provided opposite to the first baffle 111 and a wire channel 133 is defined by the first block 134 together with the first baffle 111. Further, the first partition plate 132 divides the second wire outlet part 13 into a first winding area 135 and a second winding area 136, and the first baffle 111 is only provided corresponding to the first winding area 135. The first block 134 is located in the first winding area 135 to divide the first winding area 135 into an initial winding area 137 close to the second winding area 136 and a series winding area 138 in an opposite direction from the second winding area 136. Further, the second wire outlet part 13 includes a plurality of poles 139 provided in the initial winding area 137, the series winding area 138, and the second winding area 136, respectively.
The first winding unit 30 is arranged on the winding part 11 and a line of the first winding unit 30 penetrates through the first wire outlet part 12. On the other hand, referring to FIG. 5, the second winding unit 40 includes a first winding segment 401, a second winding segment 402, and a third winding segment 403. The first winding segment 401 enters from the initial winding area 137 and winds on the winding part 11 through the wire channel 133. The second winding segment 402 is connected with the first winding segment 401, and enters the series winding area 138. The third winding segment 403 is connected with the second winding segment 402, and a line of the third winding segment 403 penetrates into the series winding area 138 without contacting with the wire channel 133 to wind around the winding part 11 and then protrude from the second winding area 136. Further, the second winding unit 40 is implemented by a metal wire in succession, that is, the first winding segment 401, the second winding segment 402, and the third winding segment 403 are continuous segments. One end of the metal wire is wound on one of the plurality of poles 139 which is located in the initial winding area 137, and then enters the winding part 11 through the wire channel 133 to be wound on the winding part 11 in a predetermined number of turns, for example, the predetermined number of turns are two turns, which is referred to as the first winding segment 401 in the present invention. Next, the metal wire passes through one side of the first baffle 111 which is opposite the second winding area 136, and extends toward the series winding area 138 to be wound around one of the plurality of poles 139 which is located in the series winding area 138 to form the second winding segment 402. Thereafter, the metal wire further extends from the series winding area 138 toward the winding part 11, at the time the metal wire is directly extended toward the winding part 11 without contacting with the wire channel 133, and the metal wire is further wound on the winding part 11 in a desired number of turns, for example, the predetermined number of turns are two turns as referred to herein. Finally, the metal wire protrudes from the second winding area 136 to form the third winding segment 403 which is laminated over the first winding segment 401. Further, the first winding segment 401 and the second winding segment 402 form a first sub-winding unit, and the third winding segment 403 form a second sub-winding unit in series with the first sub-winding unit. The first sub-winding unit and the second sub-winding unit form the second winding unit 40 of the present invention. Accordingly, in the winding process of the second winding unit 40 of the present invention, the first winding segment 401 and the third winding segment 403 are separated by the first baffle 111 and the first block 134, so that a sleeve is not required to separate the segments which will be contacted when the second winding unit 40 is wound, that is, the winding process of the second winding unit 40 will be subtracted from a portion where the sleeve is mounted, and thus the winding of the second winding unit 40 can be carried out mechanically and automatically.
Referring to FIG. 2, FIG. 3, FIG. 4 and FIG. 5, in one embodiment, the second wire outlet part 13 includes a first wiring trough 140 provided on the first inclined surface 131 where is opposite to the initial winding area 137, and the first wiring trough 140 provides the first winding segment 401 to be wound along a surface thereof so as to avoid other segments. In addition, in one embodiment, the winding part 11 includes a second block 113 connected with the first partition plate 132, and the second block 113 includes a connection portion 114 connected to the first partition plate 132 and a nose portion 115 which extends from the connection portion 114 and protrudes toward the second winding area 136. In one embodiment, a thickness of the second block 113 is increased from the nose portion 115 toward the connection portion 114. Further, the winding part 11 includes a central axis 116, one side of the first baffle 111 facing the central axis 116 includes a first distance 117 with the central axis 116, and one side of the second block 113 facing the central axis 116 includes a second distance 118 with the central axis 116.
Referring to FIG. 4, in one embodiment, the second wire outlet part 13 includes two first retaining walls 141 located on two sides of the first inclined surface 131, one of the two first retaining walls 141 located within the first winding area 135 and the first block 134 together define a wire channel 142 to provide the metal wire passing through the series winding area 138. The wire channel 142 is provided to specifically limit a position of the metal wire during the winding.
Referring to FIG. 4, in addition that the second wire outlet part 13 is provided with a wire isolation structure, the first wire outlet part 12 is also designed with a wire isolation structure for winding. In one embodiment, the first wire outlet part 12 includes a second inclined surface 121 facing the winding part 11, a second partition plate 122 provided on the second inclined surface 121, and a second wiring trough 123 provided on one side of the second inclined surface 121 close to the winding part 11. Further, the second partition plate 122 divides the first wire outlet part 12 into a third winding area 124 and a fourth winding area 125, and one side of the second partition plate 122 is formed with a first wire supporting notch 126 where is facing the winding part 11. Also, the second wiring trough 123 is only located in the third winding area 124. Further, the first wire outlet part 12 includes a third partition plate 127 provided in the third winding area 124, and the third partition plate 127 and the second partition plate 122 are located at two sides of the second wiring trough 123, respectively. In addition, the first wire outlet part 12 includes a fourth partition plate 128 disposed between the second partition plate 122 and the third partition plate 127, and the fourth partition plate 128 is parallel to the second partition plate 122. One side of the fourth partition plate 128 is formed with a second wire supporting notch 129 where is facing the winding part 11 and the fourth partition plate 128 is not disposed inside the second wiring trough 123. In one embodiment, the first wire outlet part 12 includes two second retaining walls 120 on two sides of the second inclined surface 121. Accordingly, when the first winding unit 30 is wound, the step of mounting the sleeve is also eliminated, so that the transformer 100 can be automatically wound.
