Abstract

The invention provides a transformer or inductor winding structure. The transformer or inductor winding structure is that a primary or secondary coil is composed of a plurality of winding units; each winding unit is a flat coil which has the same shape and densely coiled in the same plane; the flat coil is annular or of a rectangular shape with a hole; insulating layer materials are arranged between the winding units; each winding unit a top-bottom double-flat coil which is electrically connected in the same spiral direction. According to the scheme, the transformer or inductor winding structure has the advantages that the preparation efficiency of a transformer or an inductor is greatly increased, the consistency and transformer quality are ensured, the coupling coefficients of the transformer coils are increased, and as a result, the transformer efficiency is increased.

Description

A kind of transformer or inductor winding structure

One, technical field

The present invention relates to a kind of transformer or inductor winding structure.

Two, background technology

Winding construction in traditional transformer and inductance manually uses coil winding machine and rapidoprint to complete successively in certain sequence, and processing cost increases day by day, and efficiency is lower; Be coiling owing to being people again, its consistency is difficult to ensure.

But prior art has developed novel transformer: as CN2012102277490 provides a kind of integrated circuit transformer, integrated circuit transformer is arranged on substrate.Integrated circuit transformer comprises: First Line round metal pattern, comprises inner round portion and outer perimeter section; Second coiled type metal pattern, laterally between inner round portion and outer perimeter section; Dielectric layer, is arranged on First Line round metal pattern and the second coiled type metal pattern; First through hole, is formed through dielectric layer, and is electrically connected to First Line round metal pattern and the second coiled type metal pattern one of them; First reroutes pattern, is arranged on dielectric layer, is electrically connected to the first through hole and extends along the first through hole, wherein first to reroute pattern covers First Line round metal pattern and the second coiled type metal pattern at least partially at least partially.But the product of said structure can not be applicable to current mode transformer or inductor winding product.

Three, summary of the invention

The present invention seeks to, propose a kind of transformer or inductor winding structure, greatly can improve the preparation efficiency of transformer or inductance, ensure the quality of consistency and transformer; Strengthen the coupling coefficient between transformer coil, thus improve transformer efficiency.

Technical scheme of the present invention is: a kind of transformer or inductor winding structure, and simple or secondary coil is made up of some winding elements, each winding element be same plane that shape is identical close around planar coil, planar coil is annular or rectangle with holes; Between winding element, there is insulating barrier.

Further, each winding element is upper and lower two planar coil, and two planar coil is the same hand of spiral of electrical connection up and down.

Further, two planar coil unit is respectively by simple and secondary coil crossing stack.

The electric connecting joint that two connector lugs of each winding element all have convex-concave to join.

The connector lug of all original grade coil windings is distributed in a side of transformer or inductance component, and the connector lug of all secondary coils is distributed in the another side of transformer or inductance component.Then line is very convenient.The coil of certain employing enamelled wire is the most common.

The winding element structure that two planar coil is formed up and down is shown in Fig. 3.

The invention has the beneficial effects as follows: propose a kind of transformer or inductor winding structure, greatly can improve the preparation efficiency of transformer or inductance, ensure the quality of consistency and transformer; Strengthen the coupling coefficient between transformer coil, thus improve transformer efficiency.Adopt and first use the different winding of automation equipment coiling, one-body molded, again different winding " is imbedded multilayer printed board " (with glass mat lamination successively between group) by set order, complete the winding construction of whole device, ensure consistency, the reliability of product, improve make efficiency, meet and produce in enormous quantities, reduce cost of manufacture.

Accompanying drawing illustrates:

Fig. 1 is double-winding structure stereogram in the embodiment of the present invention;

Fig. 2 is another kind of double-winding structure schematic diagram;

Double winding unit superimposed (taking apart) structural representation in Fig. 3.

Embodiment

See accompanying drawing 1,2, by the technique of self-adhesion, each winding element 1 (is comprised double winding cellular construction, Fig. 1,2 is all like this) coiling sizing, namely use same plane that winding equipment coiling shape is identical close around planar coil 1, again some winding elements " are imbedded multilayer printed board, completely cut off and melting of heating (epoxy resin or PET resin are all operable insulating resins) at winding element compartment with the insulating barriers such as similar glass mat (insulating barrier of insulation film or liquid embedding) 2.Make gap location uniform filling glass fibre or/and insulating resin material, reach mutually insulated, ensure insulating reliability, these can be completed by tool fixture automation, thus reach the structural integrity of product and reliable consistency, improve make efficiency.In Fig. 3, double winding unit is superimposed takes rear structural representation apart.Double winding unit is that real bottle structure ensures again insulation in fact.Simple and connector lug that is secondary coil winding is distributed in the different directions (left or right limit) of transformer or inductance; The electric connecting joint that two connector lugs of coil (adopt enamelled wire coiling) itself all have convex-concave to join; Simply connect.

Especially insulating barrier 2 is the shape identical with planar coil plane.

Each winding element is upper and lower two planar coil 1-1,1-2, and two planar coil is the same hand of spiral of electrical connection up and down; The winding element structure that two planar coil is formed up and down is shown in Fig. 3, can be that identical two planar coils such as following martingale then becomes Fig. 3 structure: one of them plate coil upset plane, and is electrically connected by the line end being positioned at central authorities.Can certainly coiling time Fig. 3 structure.

Each winding element wire diameter and the number of turn all can be prepared arbitrarily according to the design parameter of transformer.

Simple and secondary coil winding element crossing stack.Insulating barrier is had between simple and secondary coil winding element.The connector lug of all simple (or secondary) coil windings is distributed in a direction (other direction) of transformer or inductance component; Then connector lug line is very convenient, forms simple and whole winding that is secondary coil.The coil of certain employing enamelled wire is the most common.Simple and secondary coil winding element is enclosed within magnetic core or permeability magnetic material again, forms transformer or inductance; Also can be air core inductor.
