Abstract

The utility model discloses an amorphous nanocystalline magnet ring which comprises a magnet ring body (1) and an insulation protection casing (2). The magnet ring body (1) is in a trace shape and made of amorphous nanocrystalline. A wire of a direct-current filter penetrates through the magnet ring (1) to be used as a magnet ring single turn, and inductance can be increased by increasing the number of the magnet ring bodies (1). The amorphous nanocrystalline magnet ring can effectively reduce the height of the filter so as to reduce manufacture cost of the filter, save space and be wide in application. Simultaneously the amorphous nanocrystalline magnet ring is made of amorphous nanocrystalline, so that common mode interference of equipment can be effectively restrained.

Description

A kind of amorphous nano-crystalline magnet ring

Technical field

The utility model relates to anti-interference magnet ring technical field, refers to especially a kind of amorphous nano-crystalline magnet ring.

Background technology

Not only other electronic equipment normal operations of severe jamming of the electromagnetic wave of electronic equipment radiation and leakage cause functions of the equipments disorder, error of transmission, also threaten human health and safety, endanger very large.Therefore, the electromagnetic interference of reduction electronic equipment has been the problem that must consider.Suppressing electromagnetic interference with magnet ring is economical and convenient and effective method has been widely used in various military or civilian subsets.

In powerful device, mostly equipment connects filter by copper bar, so the factors such as the size of copper bar, creepage distance, electric clearance have determined the size of magnet ring internal diameter.In the prior art, in order to meet the needs of production, often the height of magnet ring is higher, causes the filter height also to increase thereupon, has not only increased the manufacturing cost of filter, and has been not suitable for being applied in to highly conditional place.

The utility model content

The technical problem that the utility model solves is to overcome in the prior art because the height of magnet ring causes the defectives such as the high and magnet ring range of application of filter manufacturing cost is limited, and a kind of amorphous nano-crystalline magnet ring is provided.

For overcoming above-mentioned technical problem, a kind of amorphous nano-crystalline magnet ring that the utility model provides comprises, magnet ring, insulation protective case.Magnet ring be shaped as racetrack, made by amorphous ﹠ nanocrystalline.In DC filter, the quantity of magnet ring is directly proportional with inductance value, if increase inductance value, the quantity that only needs to increase magnet ring gets final product.Because magnet ring is that amorphous nano-crystalline is made, this material is conductor, so the outside need add the insulation protective case, the insulation protective case is made by polybutylene terephthalate (PBT).In the utility model, the outer ring length of described magnet ring is 104mm, and outer ring width is 61mm; Interior ring length 64mm, inner ring width 41mm; Highly be 30mm.

In summary it can be seen that the beneficial effect of a kind of amorphous nano-crystalline magnet ring provided by the utility model is:

1, adopts the racetrack design, greatly reduce the height of filter, thereby reduced the cost of manufacture of filter, save the space, be widely used.

2, the magnet ring material is amorphous nano-crystalline, and this soft magnetic material has preferably inhibitory action to common mode disturbances, and in addition, inductance and electric capacity consist of filter network, have further strengthened inhibitory action.

Description of drawings

Fig. 1 is the plane structure chart of a kind of amorphous nano-crystalline magnet ring of the utility model;

Fig. 2 is the stereogram of a kind of amorphous nano-crystalline magnet ring of the utility model.

Among the figure: 1 magnet ring, 2 insulation protective cases.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.

Below be a kind of embodiment of the present utility model, shown in Figure 2 such as Fig. 1, a kind of amorphous nano-crystalline magnet ring that provides comprises magnet ring 1 and insulation protective case 2.In powerful device, equipment adopts copper bar to be connected with filter mostly, the internal diameter of magnet ring 1 depends on the size of copper bar, the factor such as creepage distance and electric clearance, in order to satisfy need of production, can reduce again the height of magnet ring, so the shape of magnet ring described in the utility model 1 adopts the racetrack design.Magnet ring 1 adopts amorphous nano-crystalline to make, and the magnet ring 1 of being made by this material can produce good inhibitory action to the common mode disturbances of equipment; Itself and filter network acting in conjunction can produce better inhibitory action to common mode disturbances.Because amorphous nano-crystalline is conductor, so the outside need add insulating sleeve 2, it is made by polybutylene terephthalate (PBT).In DC filter, the quantity of magnet ring 1 is directly proportional with inductance value, if will increase inductance value, the quantity that only needs to increase magnet ring 1 gets final product.The preferred 104mm of outer ring length of magnet ring 1, the preferred 61mm of outer ring width; The preferred 84mm of interior ring length, the preferred 41m of inner ring width; Highly preferred 30mm.

Those of ordinary skill in the field are to be understood that: the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
