Detailed description of relevant the utility model and technology contents, with the conjunction with figs. explanation as follows, yet appended accompanying drawing is not to be used to limit to the utility model only as illustrative purposes.
Please refer to Fig. 1 to Fig. 6, the utility model provides a kind of transformation module with composite type drum stand, transformer 1 wherein (being designated hereinafter simply as " transformer 1 "), and it comprises: a base 10, a plurality of drum stand 20, a plurality of secondary coiling group 30, and twocore 40.
In the transformer 1 of the utility model; The all visual actual needs of the position of first pin 112 and second pin 113 and quantity is adjusted; The also visual actual needs of the position of first conduit 122 and second conduit 123 and quantity is adjusted; So be merely an embodiment shown in the figure, be not in order to limitation the utility model, as long as being arranged on the base 10, first pin 112 and second pin 113 be arranged on the drum stand 20.
A plurality of drum stands 20 are disposed in the base 10, and each drum stand 20 roughly is annular and has the hollow bulb 22 of through hole 111 of an annular wire casing 21 and the corresponding base 10 of the outer rim of being arranged at; More particularly; The side of each drum stand 20 roughly be the H type and have second splint 23 and 23 '; Hollow bulb 22 is a manhole; So second splint 23,23 ' and the circular outer wall of hollow bulb 22 between just surround above-mentioned annular wire casing 21, lead 200 can be wound in this annular wire casing 21.One end of each drum stand 20 second splint 23,23 ' on be respectively equipped with a breach 24, lead 200 penetrates a breach 24 and is wound on the annular wire casing 21 and passes to form with other positions through another breach 24 and electrically connect.
Each drum stand 20 on its at least one surface (also promptly: form a plurality of salient points 25 clamping plate 23); These a plurality of salient points 25 are around these hollow bulb 22 arranged spaced and preferably for evenly distributing; These a plurality of salient points 25 protrude from this clamping plate 23 1 segment distances; Its role is to make adjacent two drum stands 20 when configuration, can produce a gap each other, this gap is the usefulness of using for the cross-ventilation heat radiation.Drum stand 20 can be by processing such as non-conductive materials such as plastic cement, also can be by processing such as conductive material such as metals.Can attach an insulating trip 13 on the dual side-edge of base 10 inside, for example industry Mylar tape commonly used.
A plurality of secondary coiling groups 30 are disposed between adjacent two drum stands 20, and each secondary coiling group 30 is roughly a C type conducting strip and constitutes, and it has the perforation 31 corresponding to the hollow bulb 22 of drum stand 20.One end bending forming of secondary coiling group 30 has two tabs 32, is fastened in order to bending on the base plate 11 of base 10 in order to the location.Can know from Fig. 2 and to find out that the tabs 32 of each secondary coiling group 30 can be designed to different length, be placed on so that stagger on the lateral margin of base 10.
What specify is, as can beappreciated from fig. 1, and in drum stand 20 is disposed at base 10 and secondary coiling group 30 when inserting between adjacent two drum stands 20 at interval respectively; The salient point 25 of each drum stand 20 all takes shape in phase the same side; Be on the surface of clamping plate 23 down in Fig. 1, thus, the salient point 25 of drum stand 20 can make against living secondary coiling group 30 and produce a gap between drum stand 20 and the secondary coiling group 30; Though the salient point 25 of the drum stand 20 of below is not against secondary coiling group 30; But still, producing a gap between drum stand 20 and the base plate 11 so still can make against living base plate 11, these gaps all help the cross-ventilation heat radiation.
In the utility model, drum stand 20 is in order to as primary side coiling group, and secondary coiling group 30 is in order to as secondary side winding.Though in Fig. 1, drum stand 20 is interconnected with secondary coiling group 30, well imagines; As long as lead connects correct; These a plurality of drum stands 20 also can adjacent one another arely dispose, and these a plurality of secondary drum stands 30 also can adjacent one another arely dispose, and not necessarily need configuration interlaced with each other.Therefore; The utility model utilizes a plurality of drum stands 20 and the composite type of secondary coiling group 30 to design, and first pin 112 and second pin 113 are not set on the drum stand 20, so can on size and transformation conversion ratio, produce the changeable design of suitable elasticity; The drum stand that does not need specialized designs different size as prior art; The special again lead winding that twines the different numbers of turn more can significantly reduce manufacturing cost, closely promotes production efficiency.
Each magnetic core 40 roughly is the E font and processes (being generally iron magnetic core) for the magnetic material; And also can be core structures such as ATQ type, EE type, ER type, ERI type, ECI type, RM type, EQ type, PQ type, PJ type or PM type; It has a main floor 41 and vertical extent in two side wings 42 of these main floor 41 2 sides; Form a magnetic axis 43 on the main floor 41; The external diameter of this magnetic axis 43 is slightly less than through hole 111, hollow bulb 22 and 31 the internal diameter of boring a hole, thus this twocore 40 can be respectively from the hollow bulb 22 of the through hole 111 of the base of cross-under up and down 10 of Fig. 1, these a plurality of drum stands 20, and the perforation 31 of these a plurality of secondary coiling groups 30 and making up.
What specify is; Two side wings 42 of each magnetic core 40 are to be coated on two side plates 12 of base 10; Thus; On the direction of two side wings 42 that are parallel to base 10 2 side plates 12 and magnetic core 40, do not receive stopping of other plate bodys; So as shown in Figure 6, cross-ventilation can be along the direction of two side plates 12 that are parallel to base 10 and the gap through being produced because of salient point 25 between drum stand 20 and the secondary coiling group 30, and the heat that by this lead winding of drum stand 20 is produced dissipates to transformer 1 outside smoothly.
In addition; Though in Fig. 1, showing drum stand 20 and secondary coiling group 30 is to be the vertical stacking configuration and to form one " rectilinear " transformer 1; But well imagine; Drum stand 20 and secondary coiling group 30 are to be the horizontal cross configuration and to form one " horizontal " transformer 1, and first pin 112 is got final product with the 113 corresponding bendings of second pin down.
With reference to figure 7, the transformation module 2 of the utility model, it has: above-mentioned transformer 1, a temperature-sensitive sticker 50, an and radiator fan 60.Temperature-sensitive sticker 50 is arranged in first conduit 122 of this transformer 1 to monitor the temperature of this transformer 1, and it is outer so that this transformer 1 is dispelled the heat that radiator fan 60 is arranged at this transformer 1.More particularly; Radiator fan 60 can be arranged on a side of transformer 1 and be parallel to two side plates of base 10; Thus, the air-flow that radiator fan 60 is blown out, gap smoothly through being produced because of salient point 25 between drum stand 20 and the secondary coiling group 30; The heat that by this lead winding of drum stand 20 is produced dissipates to transformer 1 outside smoothly, and produces splendid radiating effect.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
