Description
(1) technical field
The utility model relates to a kind of electronic component, refers in particular to a kind of magnetic material element.
(2) background technology
Utilize the inductance, transformer etc. of the production of I shape element to have a wide range of applications in modern enterprise, rapidoprint commonly used has: ferrite, magnetic core etc.The general two ends of I shape magnetic core profile are big, and middle little, two end sections and middle interconnecting piece cross section are circle, and connecting portion can wind the line in the middle of it.The shortcoming of this design is: owing to limit by profile, during the press process of conducting powder end, can't carry out one-time formed operation.After major obstacle was compacting, the circular arc evagination of middle interconnecting piece part can't the demoulding.In view of this reason, the processing method of I shape magnetic core generally has following three kinds of methods:
First kind:
The mill cutting method: first a kind of rod core of compacting, then according to the actual size specification requirement, be processed into the little I-shaped structure in big centre, two ends with methods such as green compact or product utilization mill processing or Vehicle Processing or line cut out, as shown in Figure 1.But this technological process complexity, manual operations is many, and the product precision of producing is lower, and presentation quality is relatively poor, is difficult to reach quality standards; Production cycle while is long, and manufacturing cost and waste of raw materials increase, and are confined to the ferrite sintered body magnetic element.Can not adopt the method for the bonding magnetic element,, increase magnetic element loss because the bonding magnetic element is machined or the line cutting time can produce internal stress; Because the intensity of bonding magnetic element is not very strong, so grinding, also be easy to produce during the cutting of Vehicle Processing or line and scrap.
Second kind:
Combined method: as shown in Figure 2, produce a cylinder bar magnet according to the local specification requirement of product, two cylinder thin slices bigger than cylinder bar magnet sectional area carry out bonding forming with cylinder bar magnet and cylinder thin slice again, and this method can be used in various materials.Though this way has reduced waste of material,, cause cost of labor to increase because operation is loaded down with trivial details; Consider from the product quality aspect,, can produce a large amount of noises and dispersion loss so inevitably because the abutting edge can form air gap.So poor-performing of product.
The third:
Injection moulding: though this technology can one-shot forming goes out the magnetic element of I-shape construction, even the more complicated magnetic element of structure. but the raw material that this technology is used moulding as: magnetic requires very high, granularity must be the magnetic below 20um, for ferrite sintered body, also to carry out technologies such as degreasing, sintering, because green strength extreme difference after less relatively, the degreasing of compact density, so very easily produce waste products such as distortion, cracking, accent piece in the Ferrite Material high-temperature sintering process, be difficult to the control product quality, and the production cost height.Though can not need technologies such as degreasing, sintering for the bonding magnetic element, but it must add a large amount of resins as bonding agent, so compact density is less relatively, the magnetic spaced apart is excessive, and the magnetic core internal air gap is much larger than the powder compaction product, therefore magnetic property is relatively poor, and production efficiency is also lower.
So above several method all can not fundamentally solve the quality parameter and the production cost of I-shaped magnetic element.
(3) utility model content
The utility model will solve the technical problem that existing magnetic material element can't a powder pressing forming, provide a kind of can one time powder compaction, precision height, stay in grade, moulding I shape magnetic material element that cost is low.
For solving the problems of the technologies described above, the utility model adopts a kind of magnetic material element, comprise two ends panel and middle interconnecting piece, two end cross-sectional areas are respectively greater than the sectional area of middle interconnecting piece, the two ends panel is square, the cross section of middle interconnecting piece is a track and field runway shape or square, and the straight line in the cross section of middle interconnecting piece is parallel with the limit of two ends panel.
Further, middle joint pin is a track and field runway shape, and length of side of the major diameter in connecting portion cross section and both ends of the surface is contour in the middle of it, and the minor axis in middle interconnecting piece cross section is less than the length of side of both ends of the surface.
Further, middle joint pin be square in the middle of it length of side of two length of sides in connecting portion cross section and both ends of the surface contour, other two length of sides in middle interconnecting piece cross section are less than the length of side of both ends of the surface.
After adopting said structure, the both ends of the surface of this magnetic material element are square, the cross section of middle interconnecting piece is a track and field runway shape or square, the sectional area of both ends of the surface is respectively greater than the sectional area of middle interconnecting piece, the big structure in little two ends in the middle of forming, the middle interconnecting piece sectional area equates simultaneously, and therefore being fit to therebetween, section evenly winds the line.Because the cross section of middle interconnecting piece is a track and field runway shape or square, its short diameter is less than the length of side of both ends of the surface, and from a side, the side view of this element still is I shape.Because the major diameter of middle interconnecting piece cross section and the length of side of both ends of the surface are contour, therefore from the another side, this cross section and both ends of the surface that middle interconnecting piece contains long diameter project into square, simultaneously this cross section have two limits respectively with by be positioned on the limit, upper surface a bit and the straight line that a bit is connected coincidence on limit, lower surface, middle interconnecting piece have two limits respectively with the both ends of the surface limit on 2 straight lines that are connected overlap, form two straight lines.
Advantage of the present utility model is, because each parts does not all have step from vertical view, is convenient to the vertical direction demoulding, therefore can carry out the powder compaction one-shot forming.According to the magnetic material element that such die production is come out, magnetic material is evenly distributed, regular shape and precision height.Simultaneously production process is simplified greatly, can produce in enormous quantities, and not need to carry out loaded down with trivial details manual operations as processing cutting or bonding baking.And do not have air gap, magnetic property is better, and no waste material has also greatly been saved the cost of raw material and cost of labor.
