Abstract
The utility model relates to transformer technology field, especially a kind of miniature transformer.It comprises skeleton, be arranged on magnetic core on skeleton, be wound in armature winding and secondary winding on skeleton and magnetic core, described skeleton comprises elementary sidepiece and the secondary sidepiece that is separately positioned on magnetic core both sides, described armature winding is drawn by the bottom of elementary sidepiece, and described secondary winding is by the Base top contact of secondary sidepiece; The bottom outside of described secondary sidepiece is provided with barricade.The end of a thread of armature winding of the present utility model and secondary winding is drawn respectively from different directions, has also facilitated the installation of transformer in the insulation distance of having widened between primary and secondary; Meanwhile, the barricade adding by subsides, can prevent that electricity from getting over from the gap between winding edge and skeleton and the problem that occurs puncturing, effectively suppresses the generation of arcing phenomenon, thereby improves the security performance of transformer; It is simple in structure, volume is little, has very strong practicality.
Description
Technical field
The utility model relates to transformer technology field, especially a kind of miniature transformer being applied on charger.
Background technology
At present, the electronic product that uses in life is more and more, and corresponding, these electronic products all need to be equipped with corresponding charger, with guarantee electronic product have electric weight for, so the use of charger is very frequently.Transformer is as the core component in charger, and its quality has vital impact to the performance of charger; Because the volume of transformer of charger in prior art is large, insulation distance is little, causes the volume of charger further to reduce, transformer insulated performance and interference free performance are poor; Meanwhile, existing transformer easily produces arcing phenomenon, has reduced the security performance of transformer.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of simple in structure, volume is little, insulation effect good, safe, antijamming capability is strong miniature transformer.
To achieve these goals, the utility model adopts following technical scheme:
A kind of miniature transformer, it comprises skeleton, be arranged on magnetic core on skeleton, be wound in armature winding and secondary winding on skeleton and magnetic core, described skeleton comprises elementary sidepiece and the secondary sidepiece that is separately positioned on magnetic core both sides, described armature winding is drawn by the bottom of elementary sidepiece, and described secondary winding is by the Base top contact of secondary sidepiece; The bottom outside of described secondary sidepiece is provided with barricade.
Preferably, the material of described barricade is adhesive tape, and the thickness of described barricade is 2mm.
Preferably, respectively offer five pin bores on described elementary sidepiece and secondary sidepiece, the spacing between the spacing between the pin bores of described elementary sidepiece and the pin bores of secondary sidepiece is 2.5 ± 0.1mm.
Preferably, on input the end of a thread of described secondary winding and output the end of a thread, be provided with sleeve pipe.
Preferably, the length of described skeleton, width and be highly all less than or equal to 14.5mm.
Owing to having adopted such scheme, the end of a thread of armature winding of the present utility model and secondary winding is drawn respectively from different directions, has also facilitated the installation of transformer in the insulation distance of having widened between primary and secondary; Meanwhile, the barricade adding by subsides, can prevent that electricity from getting over from the gap between winding edge and skeleton and the problem that occurs puncturing, effectively suppresses the generation of arcing phenomenon, thereby improves the security performance of transformer; It is simple in structure, volume is little, has very strong practicality.
Accompanying drawing explanation
Fig. 1 be the utility model embodiment face planar structure schematic diagram;
Fig. 2 is the right view plane structural representation of the utility model embodiment;
Fig. 3 be the utility model embodiment look up planar structure schematic diagram;
Fig. 4 is the schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the miniature transformer of the present embodiment, it comprises length, width and is highly all less than or equal to the skeleton 1 of 14.5mm, be arranged on magnetic core on skeleton 1, be wound in armature winding and secondary winding N3 on skeleton 1 and magnetic core, armature winding comprises fixedly winding N5 and adjustable winding N1, N2, N4; Wherein, skeleton 1 comprises elementary sidepiece 2 and the secondary sidepiece 3 that is separately positioned on magnetic core both sides, on elementary sidepiece 2 and secondary sidepiece 3, respectively offer five pin bores (for ease of differentiating, be labeled as respectively 1-5 and 6-10), the spacing between the pin bores (6-10) of the spacing between the pin bores of elementary sidepiece 2 (1-5) and secondary sidepiece 3 is 2.5 ± 0.1mm; Fixedly input the end of a thread of winding N5 and output the end of a thread are drawn by pin bores (4 and 5), input the end of a thread of adjustable winding N1, N2, N4 and output the end of a thread are drawn by the bottom of pin bores (1 and 2), input the end of a thread A of secondary winding N3 and output the end of a thread B be by the Base top contact of pin bores (6 and 10), is set with the sleeve pipe 4 of different colours on input the end of a thread A of secondary winding N3 and output the end of a thread B simultaneously; With this, guaranteeing that transformer has under the feature of micro volume, has widened the insulation distance between primary and secondary.
Meanwhile, in the bottom outside of secondary sidepiece 2, be also provided with barricade 5, the material of barricade 5 is that adhesive tape, thickness are 2mm; According to actual conditions, barricade 5 can be adopted the bottom that is fixed in the method for paste secondary sidepiece 2, the problem that can prevent electricity from getting over from the gap between winding edge and skeleton and occur puncturing, effectively suppresses the generation of arcing phenomenon, thereby improves the security performance of transformer.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
