Abstract
The invention relates to a wound coil. The wound coil in a spiral shape having an inner wall and an outer wall is formed by winding a rectangular-sectioned flat conductor. The peripheral surface of the conductor is composed of two opposing narrow faces and two opposing wide faces. One wide face and one narrow face which are adjacent to each other share a long edge; the other edge of the wide face, adjacent to the long edge, is a wide edge; the other edge of the narrow face, adjacent to the long edge, is a narrow edge; the wide edge is longer than the narrow edge. The narrow faces form the inner and outer walls of the spiral coil. The wide faces are perpendicular to the axis of the spiral coil. The wound coil has the advantages that winding tightness of the coil is increased, flux leakage is reduced, availability of the coil is improved, and voltage and current are stabilized; in addition, radial mechanical strength of the coil is increased, and overload capacity of the coil is improved.
Description
Technical field
The present invention relates to a kind of coil, relate to particularly a kind of coiling.
Background technology
Coil is often referred to ringwise wire winding, is widely used in the devices such as motor, inductance, transformer and loop aerial.For example, transformer is a kind of static device, for electric energy transmitting, and utilizes electromagnetic induction principle a kind of electric current of grade to be become to electric current and the voltage of another grade of same frequency between two or more coils with voltage transitions.Coil is the most basic parts of transformer, is divided into the different numbers of turn.Because the one turn voltage of different coils is the same, need to make coil have the different numbers of turn to reach different voltage.
Granted publication number discloses a kind of coil for the Chinese invention patent of CN102044330B, one side of the winding of the winding of the coiling end side of the winding consisted of many wires and coiling top side reels towards outer circumferential side from inner circumferential side, and the opposing party draws from inner circumferential side towards outer circumferential side, described many wires longitudinally stacked state are reeled together, at the cross section of the winding of the winding of described coiling end side and described coiling top side, make these many wires overlapping and intersect along the state of laterally setting level.Such coil can reduce the height of cross section significantly, forms the height identical with other zones.Yet the metal wire cross section that this coil is used is rounded, utilizes the circular metal coil of wire larger around the coil gap formed, and causes the leakage field phenomenon more serious.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of coiling of effective minimizing leakage field.
For achieving the above object, the technical solution adopted in the present invention is: a kind of coiling, the flat conductor that is rectangle by cross section turns to hollow and has a helical form of inner and outer wall around an axis, the outer peripheral face of described flat conductor is comprised of two relative broadside side narrow flank side surface relative with two, wherein an adjacent described broadside side and a described narrow flank side surface has a common long side, in the broadside side, another side adjacent with described long side is its wide side, in described narrow flank side surface, another side adjacent with described long side is its narrow side, the length of described wide side is greater than the length of described narrow side, it is characterized in that: described narrow flank side surface forms the inner and outer wall of described spiral helicine coil, described broadside side is vertical with the axis of described spiral helicine coil.
Optimally, rounded, the ellipse or square of described coil section.
Further, described coil is for being greater than 2 circles.
Because technique scheme is used, the present invention compared with prior art has following advantages: coiling of the present invention, adopt the flat metal wire to turn to the helical form with inner and outer wall, and the narrow flank side surface of flat metal wire forms the inner and outer wall of spiral helicine coil, the broadside side is vertical with the axis of coil, can improve the tightness degree of coil winding on the one hand, reduce the coil leakage field, improve coil service efficiency burning voltage and electric current; Improve on the other hand the radial mechanical strength of coil, improved its overload capacity.
The accompanying drawing explanation
Accompanying drawing 1 is coiling front view of the present invention;
The A-A cutaway view that accompanying drawing 2 is accompanying drawing 1;
Accompanying drawing 3 is coiling left view of the present invention;
Wherein: 1, broadside side; 2, narrow flank side surface.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated.
Coiling as shown in Figure 1 to Figure 3, have the inner and outer wall be parallel to each other, and by flat conductor, around an axis, turns to the cored screw shape.The cross section of flat conductor is rectangle, its outer peripheral face is connected around forming in twos by four sides, wherein two relative sides are broadside side 1, two other is narrow flank side surface 2, broadside side 1 is the rectangle surrounded by wide side a and long side c, narrow flank side surface 2 is the rectangles that surrounded by narrow side b and long side c, broadside side 1 and narrow flank side surface 2 have common long side c, and the length of wide side a is greater than the length of narrow side b, narrow flank side surface 2 forms the inner and outer wall of spiral coil, and broadside side 1 is vertical with the axis of spiral coil.Because the length of wide side a is greater than the length of narrow side b, increased the radial mechanical strength of coil, improve its overload capacity; And the every turn-to-turn arrangement of coil closely, forms the inner and outer wall of spiral coil, can reduce the coil leakage field, reduces the use of insulating material, thereby reduce costs.
In use, can be according to the difformity of iron core, the difform coil of coiling.In the present embodiment, hollow circle body 3 cross sections are rounded.In addition, because the one turn voltage of different coils is the same, coil can be arranged to the purpose that the different numbers of turn reaches regulation voltage, be widely used in the fields such as transformer, in the present embodiment, the hollow circle body number of turn is optimized for and is greater than 2 circles.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
