Abstract
The invention discloses an unframed transformer, which comprises a magnetic core, a winding and an insulating rubber tape. The magnetic core consists of two magnets. The butt joint surface of the outer sides of the two magnets is fixed by colloid. The winding is wound on middle cylindrical surfaces of the two magnets. The insulating rubber tape is wound on the surface of the winding.
Description
Technical field
The present invention relates to a kind of unframed transformer and processing method thereof.
Background technology
Now in the power electronic technology, transformer is used in a large number, and how efficient and rational the transformer that utilizes most important for properties of product.In transformer, window area has determined the utilance of magnet, the window utilance is subjected to magnet shape, the coiling specification, restrictions such as skeleton size, sometimes often because the coiling of selected transformer and designing requirement is pounded several poorly severally pounds even one pound and have to select for use larger sized transformer, this all is a kind of waste on still being space availability ratio from cost.Skeleton is as the device that a kind of magnet supports and winding is finalized the design, in theory to the electromagnetic property of device without any effect, but taken certain window area, reduced the coiling area of winding.
Summary of the invention
The invention provides unframed transformer and processing method thereof, improved the window utilance of transformer.
The present invention is achieved in that a kind of unframed transformer, it is characterized in that comprising: magnetic core, winding, insulating tape.
Magnetic core is to be made of two magnets.The outside interface of two magnets is fixed with colloid.Winding technique is on the middle cylinder of two magnets.Insulating tape is wrapped in the surface of winding.
A kind of processing method of unframed transformer is characterized in that may further comprise the steps:
(a) with colloid magnetic core is fixed, magnetic core is to be made of two magnets;
(b) at the center pillar lateral surface pad upper thin sheet of two magnets;
(c) winding and insulating tape are wound on the center pillar of two magnets that are lined with thin plate;
(d) extract thin plate out.
Be fixed together with the outside interface of colloid two magnets.Web width equates with the center pillar lateral surface width of magnet.Insulating tape is wrapped in the winding surface.
Employing the invention provides unframed transformer and processing method thereof, and is simple in structure, easy to operate, improved the window utilance of transformer.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.Fig. 1 is the structural representation that the skeleton transformer is arranged, and Fig. 2 is the structural representation of unframed transformer, and Fig. 3 is a transformer magnet structure schematic diagram of the present invention.As can be seen from Figure, unframed transformer is made of magnetic core, winding and insulating tape.Magnetic core is to be made of two magnets, and the outside interface of two magnets is fixed with colloid.Winding technique is on the middle cylinder of two magnets, and insulating tape is wrapped in the winding surface.
Fig. 4 is a processing method schematic diagram of the present invention, as shown in the figure, its processing method is as follows, at first fixes the outside interface of two magnets with colloid, two thin plates on the two lateral surface pads before and after two magnet center pillars then, the width of thin plate equates with the width of cylinder in the magnet.Winding technique is on the center pillar of two magnets that are lined with thin plate, and insulating tape is wrapped in the surface of winding, treat winding technique typing at last after, extract thin plate out.For easy to process, can on thin plate, add a little handle, be convenient to extract out thin plate.
