Abstract

It the utility model is related to a kind of coil of high frequency transformer, it includes coil rack, the coil rack is made of the tap holder of middle reel and two, copper wire is wound with the outside of the reel, the both ends of copper wire are tap, tap is clipped on tap holder, copper wire winding forms the armature winding and secondary windings of transformer afterwards on a bobbin, armature winding and secondary windings are wound on a bobbin by the way of Double-wire parallel wound, in addition the outside of every copper wire is coated with insulating tape, and the oblique outside for being wrapped in copper wire of insulating tape, copper wire is coated completely, only tap is leaked out, so as to which copper line surface is wound insulating layer.The coil of this high frequency transformer simplifies wire winding, removes layer insulation processing from, reduces labour cost, and makes coil-winding convenient, has beautified coil appearance, has improved the coupling strength and voltage efficiency of transmission of transformer.

Description

The coil of high frequency transformer
Technical field
It the utility model is related to a kind of coil of high frequency transformer.
Background technology
During transformer wound around coil, because often having safety requirements, cost limitation and multiple outputs between coil and coil Coil etc., in many cases each coil separate coiling, therefore, leakage field is inevitable.It is primary and secondary and coil turn is more Level interval it is bigger, window width is narrower, and leakage inductance is bigger, thus the number of turn, structure, riding position and core structure have to leakage field it is important Influence.
The mode of transformer Double-wire parallel wound can ensure that coil has good magnetic coupling at present, compared to more traditional master, The mode of auxiliary winding layer insulation, although Double-wire parallel wound can not eliminate whole leakage inductances, can greatly reduce leakage inductance, improve transformation The performance of device.
, will be around but transformer needs to add insulating layer between armature winding and secondary windings in winding technique at present The layer of group is spaced apart reinforcement insulation, and it also requires with multiply silk-covered wire come coiling, irising out line side online also needs to set Insulating sleeve, so just causes winding process complicated, inefficient, and the coupling strength of transformer can be caused to reduce, electricity Efficiency of transmission is pressed to reduce.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided one kind removes layer insulation processing from, and coiling is convenient, beautiful Change coil appearance, improve the coil of the coupling strength of transformer and the high frequency transformer of voltage efficiency of transmission.
What the purpose of this utility model was realized in:
A kind of coil of high frequency transformer, it includes coil rack, and the coil rack is by middle reel and two Tap holder composition, be wound with copper wire on the outside of the reel, the both ends of copper wire are tap, and tap is clipped in tap holder On, copper wire winding forms the armature winding and secondary windings of transformer afterwards on a bobbin, and armature winding and secondary windings use The mode of Double-wire parallel wound is wound on a bobbin, and the outside of every copper wire is coated with insulating tape in addition, and insulating tape is oblique The outside of copper wire is wrapped in, copper wire is coated completely, only leaks out tap, so that copper line surface is wound insulating layer.
Compared with prior art, the beneficial effects of the utility model are:
The coil of this high frequency transformer simplifies wire winding, removes layer insulation processing from, reduces labour cost, and And make coil-winding convenient, beautify coil appearance, improve the coupling strength and voltage efficiency of transmission of transformer.
Brief description of the drawings
Fig. 1 is the structure diagram of the coil of the utility model high frequency transformer.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is the enlarged drawing of copper wire in Fig. 1.
Wherein:Coil rack 1, reel 1.1, tap holder 1.2, copper wire 2, tap 3, insulating tape 4.
Embodiment
As shown in Figure 1 to Figure 4, a kind of coil of high frequency transformer is the utility model is related to, it includes coil rack 1, the line Ring framework 1 is made of the tap holder 1.2 of middle reel 1.1 and two, and the outside of the reel 1.1 is wound with copper wire 2, the both ends of copper wire 2 are tap 3, and tap 3 is clipped on tap holder 1.2, and copper wire 2 forms transformation after being wrapped on reel 1.1 The armature winding and secondary windings of device, armature winding and secondary windings are wrapped on reel 1.1 by the way of Double-wire parallel wound, In addition the outside of every copper wire 2 is coated with insulating tape 4, and the oblique outside for being wrapped in copper wire 2 of insulating tape 4, and copper wire 2 is complete Full cladding, only leaks out tap 3, so that 2 surface wrap of copper wire is formed insulating layer, so just keep away eliminate layer insulation and Turn-to-turn insulation processing, simplifies the wire winding of coil, and coiling is convenient, beautifies coil appearance, improves the magnetic of transformer Stiffness of coupling and voltage efficiency of transmission.
