Abstract
The invention relates to a transformer, which comprises an iron core 1, at least two coils wound on the iron core 1, and leads 3 connected to the ends of the coils 2 and positioned outside the coils 2, wherein the two coils are formed by winding the same wire. As the coils without lead connectors are adopted, the transformer has the characteristics of high reliability, long service life and low cost.
Description
Technical field
The present invention relates to a kind of transformer, particularly a kind of transformer without pigtail splice.
Background technology
In the prior art, each coil is formed by a lead-in wire winding at least, and the two-winding transformer that is made of this coil has a plurality of pigtail splices, a plurality of pigtail splices must be interconnected.This structure has a plurality of pigtail splices and leading wire joint is connected technogenic influence possibility fracture, so that the transformer reliability is low, useful life short, and pigtail splice connects complex process, cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of transformer without pigtail splice.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of transformer, comprise iron core 1, winding at least two coils 2 on the described iron core 1, be connected with the end of described coil 2 be positioned at lead-in wire 3 outside the described coil 2, at least two coils 2 all are to form with the continuous winding of single line.
Preferably, described coil 2 is two.
Because technique scheme is used, the present invention compared with prior art has the following advantages: because the present invention adopts the continuous winding of same lead-in wire to become coil, can eliminate the impedance that is caused by pigtail splice, improve reliability and the useful life of transformer; In addition, need not the connecting lead wire joint, cost is lower.
Description of drawings
Accompanying drawing 1 is the front view of a kind of transformer of the present invention.
Accompanying drawing 2 is the end view of a kind of transformer of the present invention.
Accompanying drawing 3 is two coil-winding schematic diagrames of a kind of transformer of the present invention.
Accompanying drawing 4 is the schematic diagram of a kind of transformer of the present invention.
In the above accompanying drawing: 1, iron core; 2, coil; 3, lead-in wire.
Embodiment
Below in conjunction with accompanying drawing summary of the invention of the present invention is elaborated with a kind of preferred embodiment.
In conjunction with seeing figures.1.and.2, illustrated a kind of transformer, comprise iron core 1, winding at least two coils 2 on the described iron core 1, be connected with the end of described coil 2 be positioned at lead-in wire 3 outside the described coil 2, at least two coils 2 all are to form with the continuous winding of single line.
In conjunction with reference to Fig. 3 and shown in Figure 4, described coil 2 is two in a preferred embodiment, and the first coil has lead-in wire a end and a end ＇, and the second coil has lead-in wire b end and b ＇ end, and wherein a ＇ holds that to be connected with b ＇ be continuously connection.Can eliminate the impedance that is caused by pigtail splice like this, improve reliability and the useful life of transformer; In addition, need not the connecting lead wire joint, cost is lower.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (2)
