Abstract
The invention discloses a wire-covered transformer comprising at least two coil windings, wherein each coil winding comprises a magnetic core, a coil sheathed on the magnetic core, and an insulating tape covering the coil; and the coil is formed by winding a self-adhesion enamelled wire. The invention also discloses a method for manufacturing the wire-covered transformer. The invention omits the coil holder part, thereby effectively reducing the production cost of the transformer and solving the problem in designing the large-inductance-value transformers. The method has competitive advantages in the aspect of raw materials. The method for making the wire-covered transformer can greatly enhance the production efficiency, thereby enhancing the competitive strength of enterprises.
Description
Technical field
The present invention relates to transformer, relate in particular to transformer coil structure of a kind of line packet mode and preparation method thereof.
Background technology
Fast development along with China's electron trade, various new technologies are constantly upgraded in whole industry and are used, and as being most widely used transformer in the electron trade, also in transformation that is constantly realizing new technology and application, one group of coil of present transformer all is by coil holder, coil, magnetic core and adhesive tape four parts constitute, and the coil holder in the transformer plays an important role, those skilled in the art is constantly studying and improvement coil holder, as China Patent No. be: 2008200079935,2008202072663, the patent of the transformer wire frame structure improvement of 2008201249149 grades, purpose is in order constantly to overcome the shortcoming that existing transformer exists, go to strengthen Enterprises'Competitiveness, but it is many that its design has increased on cost, production technology is also more complicated, and production efficiency has also been reduced.Existing improvement research to transformer is not considered and how is effectively gone the problem that reduces cost and enhance productivity, design at some ADSL transformers, for ask for something than big inductance quantity, when the resistance of DCR copper has strict the restriction, use coil holder and just do not reach good effect, can not be on coil holder routing fuller.
Therefore, how realizing not only having improved transformer coli winding but also reduced its cost and enhance productivity is a technical problem that needs to be resolved hurrily in the industry.
Summary of the invention
The present invention will solve the technical problem that existing transformer device structure is complicated, cost is higher and production efficiency is not high, provides a kind of and not only can save production cost but also improve line packet mode transformer of its production efficiency and preparation method thereof.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of line packet mode transformer, comprise at least two coil windings, and wherein: described coil windings comprises magnetic core, be enclosed within the coil on this magnetic core and wrap in insulating tape three parts on this coil.
Wherein, described coil is by the Self-binding cord coiled.
Wherein, described Self-binding cord is a self-adhesive enameled wire.
Also disclose a kind of manufacture method of line packet mode transformer, it may further comprise the steps:
A, Self-binding cord is passed the alcohol of alcohol trough, make Self-binding cord be stained with alcohol;
B, with Self-binding cord on the roll of coil winding machine, and reserve a termination;
C, coil winding machine drive roll and rotate Self-binding cord winding the becoming coil that will speckle with alcohol;
D, the Self-binding cord that will wind coil one end are cut off, and are reserved another termination;
E, the coil that winds is taken off and wraps insulating tape from roll;
F, with the magnetic core string in coil obtains coil windings;
G, at least two above-mentioned coil windings are assembled into transformer.
Wherein, described Self-binding cord is a self-adhesive enameled wire.
Compared with prior art, coil windings in the line packet mode transformer of the present invention is made of to change into by coil, magnetic core and adhesive tape three parts original coil holder, coil, magnetic core and adhesive tape four parts and constitutes, saved the coil holder part, reduced the production cost of transformer effectively, solved the design challenges of big inductance quantity transformer (as: traditional E P07 transformer) simultaneously, on raw material, have more competitive advantage, the manufacture method of line packet mode transformer can be enhanced productivity greatly, thereby improves Enterprises'Competitiveness.

The schematic diagram that Fig. 2 is a coil of the present invention on the roll;
Fig. 3 is the schematic diagram after coil Self-binding cord of the present invention is cut off;
Fig. 4 is the schematic diagram that coil of the present invention takes off from roll;
Fig. 5 is the exploded view of coil windings of the present invention.
Embodiment
The coil windings of existing transformer is to be made of coil holder, coil, magnetic core and insulating tape four parts, and the present invention is made of coil 2, magnetic core 1 and insulating tape (not shown) three parts, as Fig. 1 a, Fig. 1 b and shown in Figure 5, thereby directly saved coil holder, save the production cost of power transformer product, on raw material, have more competitive advantage.
Line packet mode transformer of the present invention, comprise at least two coil windings, coil windings comprises magnetic core 1, be enclosed within the coil 2 on this magnetic core and wrap in insulating tape three parts on this coil, coil 2 is by Self-binding cord 3 coileds, make between line and the line and can cling mutually together, make the coil can be not loose, this Self-binding cord 3 can be self-adhesive enameled wire.Solve the technical barrier of big inductance quantity as traditional EP07 type transformer by improvement of the present invention, and reached preferable effect.
The manufacture method of line packet mode transformer: the Self-binding cord of using (as: self-adhesive enameled wire) is passed the alcohol of alcohol trough, make Self-binding cord be stained with alcohol, owing on the surface of Self-binding cord own chemical substance is arranged, toughness will become when this chemical substance runs into alcohol; Self-binding cord on the roll 4 of automatic coil winding machine, and is reserved a termination and is connected to be ready for use on power supply or load; Automatic coil winding machine drive roll 4 rotates the Self-binding cord winding that will speckle with alcohol becomes coil, and the size of coil can be controlled setting as required; The Self-binding cord of coil one end that winds is cut off, and reserved another termination in order to being used for being connected with power supply or load; Behind the coil wink-dry to be wound it is taken off and wraps insulating tape from roll; Ready magnetic core string in fixing coil, has just been obtained coil windings; At last with at least two above-mentioned coil windings by being assembled into transformer.Reduce cost as traditional EP07 type transformer the application of the invention method and also to improve simultaneously its production efficiency greatly; Need routing to expire the transformer of coil, adopt the very big effect of the present invention's performance, can glue mutually between line and the line just can be around coil that must be bigger.
Abovely the present invention is specifically described, but those skilled in the art can make numerous variations or variation to these execution modes these changes and change and to fall within the scope of protection of the invention in conjunction with better embodiment.
