Abstract
The utility model discloses an amorphous strip winding magnetic core without a plastic protection box. The amorphous strip winding magnetic core without the plastic protection box comprises an amorphous winding strip. Resin is coated on the amorphous winding strip, insulated rubber tapes are wound outside the amorphous winding strip, and insulating paint is sprayed outside the insulated rubber tapes. By bonding and coating of the amorphous winding strip, the amorphous strip wound magnetic core does not need the plastic protection box, and therefore an occupied space of the magnetic core is reduced by about one third, a manufacture rate of related products is improved, copper loss and coil internal resistance are reduced by reducing coil winding length, heat-dissipation performance of the magnetic core is improved, and product power density is improved.
Description
Technical field
The utility model relates to the electrical engineering technical field, is specifically related to a kind of amorphous band coiling magnetic core that need not plastic protecting kit.
Background technology
Development along with modern industry, amorphous band coiling magnetic core is because it has numerous advantages such as high-strength tenacity, good magnetic and simple manufacturing process, scope and the occasion used are more and more many, such as amorphous transformer, pulsactor, Spike-killers, magnetic amplifier, Switching Power Supply etc.These equipment mostly require very high power density, namely under the same power condition, cube to minimize, and purpose amorphous band coiling magnetic core all need a plastic protecting kit, thereby have following shortcoming: increase the integrated transformers volume; The magnetic core heat dispersion is low; Waste copper cash, instrument transformer product increase the copper resistance, and transformer increases copper loss; Limited the amorphous magnetic core size.
Summary of the invention
For defective or the deficiency of prior art, the purpose of this utility model is to provide a kind of amorphous band coiling magnetic core that need not plastic protecting kit.With by to the bonding of band and coating, make the magnetic core of amorphous band coiling no longer need plastic protecting kit.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of amorphous band coiling magnetic core that need not plastic protecting kit; comprise the amorphous winding band, it is characterized in that, be coated with resin on the band of described amorphous winding band; the outside of described amorphous winding band is wound with insulating tape, and described insulating tape external spray has insulating varnish.
The amorphous band coiling magnetic core that need not plastic protecting kit of the present utility model passes through the bonding of band and applies, the magnetic core that amorphous band is reeled no longer needs plastic protecting kit, and then magnetic core is taken up space reduce about 1/3, improved simultaneously the manufacturing rate of Related product; Thereby the minimizing line holds line length and has reduced copper loss and the internal resistance of line bag; Improved the magnetic core heat dispersion, the product power density also is improved.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Embodiment
With reference to figure 1; the amorphous band coiling magnetic core that need not plastic protecting kit of the present utility model comprises the amorphous winding band, is coated with resin on the band of amorphous winding band; the outside of the amorphous winding band that is wound in is wound with insulating tape, and the insulating tape external spray has insulating varnish.The manufacture method of this magnetic core is as follows: soak amorphous band with resin first, make and be coated with resin on the band, wound core afterwards, then use the insulating tape of about 1/2 (external diameter-internal diameter) width to twine the closely also setting of amorphous band interlayer applying that the parcel magnetic core makes coiling, put it into again the high-temperature cabinet oven dry and make the wound core layers cementing; After the oven dry magnetic core is carried out shaping, then after again with high strength insulating varniss spraying or plastic, magnetic core surface and amorphous band are cut edge form thin smooth, the continuous insulating barrier of one deck.The amorphous magnetic core that makes is owing to use resin that the amorphous band coiling is partly closely bonded together, and the permanent protection that can play magnetic core makes the magnetic core stable performance, need not to re-use plastic protecting kit; And the magnetic core the smooth of the edge can not damage the enamelled wire coat of paint during coiling line bag.
This magnetic core insulating varnish coating thickness in preparation process is easy to control, the high coating of production efficiency is even, and an application can realize the application thickness of 0.1mm～0.5mm, and outward appearance is beautiful, and insulating barrier is thin and dielectric strength is high.Products obtained therefrom is suitable for the occasions such as small-sized and miniature amorphous transformer, pulsactor, Spike-killers, magnetic amplifier, Switching Power Supply to be used.
Claims (1)
1. amorphous band coiling magnetic core that need not plastic protecting kit; comprise amorphous winding band (1); it is characterized in that; be coated with epoxy-based lacquers on the band of described amorphous winding band (1); the outside of described amorphous winding band (1) is wound with insulating tape (2), and described insulating tape (2) external spray has insulating varnish (3).
