Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-2, embodiment 1 of the present invention provides an iron core for an alpha coil, which comprises the following three-layer structure from top to bottom: the multi-connected alpha coil is formed by connecting a plurality of wire cakes 5 (namely small coils) in series, a plurality of copper sheets 4 and a plurality of wire cakes 5 are generally arranged on the first central column 11 of the first E-shaped plate 1 in a stacking interval state during assembly, the plurality of copper sheets 4 and the plurality of wire cakes 5 are also arranged on the second central column 21 of the second E-shaped plate 2 in a stacking interval state, the overall height of the second central column 21 is generally smaller than the overall height of the first central column 11, therefore, the number of the wire cakes 5 and the copper sheets 4 on the second central column 21 is less than that of the first central column (the number is not absolute, and can be adjusted according to actual requirements), and after the plurality of the wire cakes 5 on the first central column 11 are connected in series, the plurality of the wire cakes 5 on the second central column 21 are connected with the second central column 21 in series, so that all the plurality of the wire cakes 5 are connected in series.
Wait that all line cake 5 and copper sheet 4 all assemble the back, laminate the laminating together from top to bottom with second E template 2 and first E template 1 again, opening direction between them all up, opening opposite direction setting with two E templates is not like prior art, just so can not appear line cake 5 or copper sheet 4 and pop out the center pillar position when the assembly, so that do not well fix a position the center pillar on two E templates, do not need artifical manual messenger to push down copper sheet 4 and coil, first center pillar 11 on the first E template 1 assembled and second center pillar 21 on the second E template 2 are located same vertical axis, at last the bottom surface of I template 3 and the plane of opening direction place of second E template 2 are in the same place tightly hugged closely together, just so formed a complete iron core structure.
It should be noted that, in this embodiment, the height of the first center pillar 11 is consistent with the depth of the groove on the first E-shaped board 1, the height of the second center pillar 21 is consistent with the depth of the groove on the second E-shaped board 2, and the height of the first center pillar 11 on the first E-shaped board 1 is also consistent with the height of the stacked plurality of wire cakes 5 and the plurality of copper sheets 4, and the height of the second center pillar 21 on the second E-shaped board 2 is consistent with the height of the stacked two copper sheets 4 and one wire cake 5, so that after the three of the first E-shaped board 1, the second E-shaped board 2 and the I-shaped board 3 are vertically bonded together, the top surface of the first center pillar 11 will contact with the bottom surface of the second E-shaped board 2, so that the plurality of wire cakes 5 and the plurality of copper sheets are firmly pressed on the first center pillar 11, the connection is tighter, and by the same principle, the top surface of the second center pillar 21 will contact with the bottom surface of the I-shaped board 3, so that the two copper sheets 4 and one coil are firmly pressed on the second center pillar 21.
As shown in fig. 3 and 4, the difference between the embodiment 2 and the embodiment 1 lies in that the two sides of the bottom of the second E-shaped plate 2 and the I-shaped plate 3 are both provided with a clamping groove 601, so that the bottom surfaces of the second E-shaped plate 2 and the I-shaped plate 3 form a "convex" structure, and the width of the part protruding in the "convex" structure is the same as the width of the groove on the first E-shaped plate 1 and the second E-shaped plate 2, so that during assembly, only the clamping grooves 601 on the two sides of the bottom of the second E-shaped plate 2 are required to be clamped with the first E-shaped plate 1, and the clamping grooves 601 on the two sides of the bottom of the I-shaped plate 3 are required to be clamped with the second E-shaped plate 2, so that the protruding parts of the two bottoms of the two parts are respectively embedded into the grooves on the first E-shaped plate 1 and the second E-shaped plate 2, and thus the connection between the first E-shaped plate 1, the second E-shaped plate 2 and the I-shaped plate 3 is more stable, and the position deviation does not occur, and the upper and lower butt joint position of the center pillar is more accurate.
However, it should be noted that the above-mentioned arrangement in embodiment 2 needs to deepen the overall depth of the grooves on the first E-shaped board 1 and the second E-shaped board 2, at this time, the height of the first center pillar 11 on the first E-shaped board 1 needs to be smaller than the depth of the groove on the first E-shaped board 1, the height of the second center pillar 21 on the second E-shaped board 2 needs to be smaller than the depth of the groove on the second E-shaped board 2, and when assembling, the top surface of the first center pillar 11 contacts the bottom surface of the second E-shaped board 2, and the top surface of the second center pillar 21 contacts the bottom surface of the I-shaped board 3, which has the same function and effect as the above-mentioned embodiment 1.
It should be added that the height of the first center pillar 11 and the second center pillar 21 in the above embodiment is determined by the number of the wire cakes 5 and the copper sheets 4, the number of the wire cakes 5 on the first center pillar 11 and the second center pillar 21 can be 2, 3, 4 or more, generally not more than 10, the number of the copper sheets 4 can be one more than that of the wire cakes 5, that is, if the wire cakes 5 are n, the number of the copper sheets 4 is n +1 (where n is a positive integer greater than or equal to 1), the number of the copper sheets 4 can also be consistent with the number of the wire cakes 5, that is, if the wire cakes 5 are n, the number of the copper sheets 4 is also n (where n is a positive integer greater than or equal to 1), and the number can be adjusted according to the actual design requirements, and is not limited to the number designed in this embodiment.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
