Abstract
The utility model discloses a high frequency transformer which comprises a magnetic core, a primary winding and a secondary winding. Insulation adhesive tape is arranged between the primary winding and the secondary winding. One end of the insulation adhesive tape exceeds the edge of the primary winding. The high-frequency transformer has the advantages of being good in insulation effect, simple in operation and less in consumed time.
Description
Technical field
The utility model belongs to a kind of switching mode power supply transformer, especially relates to a kind of high frequency transformer.
Background technology
Along with the development of power electronic technology, Switching Power Supply relies on the feature of its high frequency to be widely used in various electronics, electric equipment, among stored-program control exchange, communication, electric power checkout equipment power supply and control appliance power supply.As the high frequency transformer of Switching Power Supply core component, its technical development is also extremely important.Therefore, from design and production technology two aspects, to improve high frequency transformer very urgent.As shown in Figure 1, armature winding 2 is close to magnetic core 1 coiling, after armature winding 2 coilings complete in order to guarantee the insulating requirements between primary and secondary, when armature winding 1 and secondary winding intersection, often by cover Teflon sleeve pipe 5, insulate, put after Teflon sleeve pipe 5 coiling insulating tape again, last coiling secondary winding, shortcoming is: bad operation in technique, after armature winding coiling completes by fluorine actor playing a supporting role pipe box on armature winding; And easily cause winding out-of-flatness, and then affect the coiling of last layer winding; In addition increase man-hour, and then high frequency transformer cost is increased.
Utility model content
The purpose of this utility model is to provide a kind of insulation effect good, the simple and coiling few high frequency transformer consuming time of technique for coiling process.
According to Yi Ge of the present utility model aspect, a kind of high frequency transformer is provided, comprise magnetic core, armature winding and secondary winding, between armature winding and secondary winding, be provided with insulating tape, one end of insulating tape exceeds the edge of armature winding.Owing to being provided with insulating tape, thereby be convenient to the insulation between armature winding and secondary winding; One end of insulating tape exceeds the edge of armature winding, being convenient to insulating tape insulate to the edge of armature winding, thereby, avoided at armature winding and the secondary group of sheathed Teflon sleeve pipe of infall, make high frequency transformer technique for coiling of the present utility model simplify and reduce coiling time loss, improved the evenness of whole high frequency transformer coiling simultaneously.
In some embodiments, magnetic core can be " work " font, and magnetic core comprises winding section, and winding section is the middle part of " work " font, thereby is convenient to armature winding and the coiling of secondary winding on magnetic core.
In some embodiments, armature winding matches with winding section, and the first end of insulating tape exceeds winding section.Thereby the first end of being convenient to the first insulating tape is coated the edge of armature winding.
In some embodiments, the first end of insulating tape is for the secondary winding of coated armature winding and secondary winding infall.Thereby, can be directly by the first end turnover of insulating tape after armature winding coiling completes, for the secondary winding of coated armature winding and secondary winding infall, handled easily, saves time.
In some embodiments, insulating tape is epoxy adhesive tape.Because epoxy adhesive tape has anti-welding, anti-puncture, matter is thin, dielectric strength is high, heatproof degree reaches 150 ℃ and anti-flaming, its HI-POT(high Potential, i.e. high voltage) more than 5KV, for the electric insulation between armature winding and secondary winding.
Accompanying drawing explanation
Fig. 1 is the structural representation of armature winding in background technology of the present utility model;
Fig. 2 is the structural representation of a kind of execution mode of high frequency transformer of the present utility model;
Fig. 3 is the structural representation of the armature winding of high frequency transformer of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 2 and Fig. 3.High frequency transformer of the present utility model, comprises magnetic core 1, armature winding 2 and secondary winding 3, between armature winding 2 and secondary winding 3, is provided with insulating tape 4, and one end of insulating tape 4 exceeds the edge of armature winding 2.Insulating tape 4 is epoxy adhesive tape.
Magnetic core 1 is " work " font, and magnetic core 1 comprises that 11， winding section 11, winding section is for the middle part of " work " font.Armature winding 2 matches with winding section 11, and the first end 41 of insulating tape 4 exceeds winding section 11.
The first end 41 of insulating tape 4 is the secondary winding 3 with secondary winding 3 infalls for coated armature winding 2.
High frequency transformer of the present utility model in the process of coiling, first coiling armature winding 2, armature winding 2 is close to winding section 11 coilings; After armature winding 2 coilings complete, insulating tape 4 is close to armature winding 2; Then secondary winding 3 is close to insulating tape 4 coilings, after secondary winding 3 coilings complete, by the first end of insulating tape 4 41 reflexeds, the edge of secondary winding 3 is coated, 4 pairs of armature windings 2 of insulating tape and secondary winding 3 carry out electric insulation.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
