Abstract
The utility model relates to a transformer iron core, which belongs to the technical field of a transformer. The utility model is designed for the convenience of winding coils on a transformer iron core. The utility model is formed by that a long strip shape soft magnetic steel sheet 1 is wound. The cross section of the utility model is provided with a circular or an elliptic longitudinal end part. The utility model is characterized in that the shape of each ring around which the soft magnetic steel sheet is surrounded is in rectangular shape, four corners of the rectangular shape are rounded corners or chamferings.
Description
The utility model belongs to the transformer technology field, refers more particularly to the iron core of transformer.
The iron core of general transformer is to press from both sides mutually with the soft magnetism steel disc to build up certain thickness amalgamation and making then, in recent years having developed as application number again is the Wound core of reeling and forming with strip soft magnetism steel disc that 95203652,5 Chinese patent literature is introduced, usually its each circle soft magnetism steel disc is surrounded is shaped as circle or ellipse, lower in coiling coil timeliness rate.
The purpose of this utility model provides a kind of transformer core, the coil of can reeling thereon easily.
The purpose of this utility model is achieved in that
A kind of transformer core of being reeled and to be formed by strip soft magnetism steel disc, its cross section has circular or oval-shaped longitudinal end, it is characterized in that: its each circle soft magnetism steel disc is surrounded is shaped as rectangle, and four angles of rectangle are fillet or chamfering.
Be shaped as the rectangle with chamfering because its each circle soft magnetism steel disc surrounds, the coil of can reeling after cover on the straight line of this rectangle is with sleeve will make things convenient at curved section coiling coil.
Introduce an embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is a schematic top plan view of the present utility model.
Fig. 2 is one of A-A cutaway view of Fig. 1.
Fig. 3 be Fig. 1 the A-A cutaway view two.
Fig. 4 be Fig. 1 the A-A cutaway view three.
Above Fig. 2, Fig. 3, Fig. 4 are respectively the A-A cutaway views of embodiment 1, embodiment 2, embodiment 3, and they have identical schematic top plan view, i.e. Fig. 1.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of transformer core of reeling and forming of the utility model by strip soft magnetism steel disc 1, its cross section has circular or oval-shaped longitudinal end, it is characterized in that: its each circle soft magnetism steel disc is surrounded is shaped as rectangle, and four angles of rectangle are fillet or chamfering.
As shown in Figure 1 and Figure 2,1 one kinds of transformer cores of reeling and forming of embodiment by strip soft magnetism steel disc 1, its cross section is circular; Its each circle soft magnetism steel disc is surrounded is shaped as rectangle, and four angles of rectangle are fillet.
As Fig. 1, shown in Figure 3,2 one kinds of transformer cores of reeling and forming of embodiment by strip soft magnetism steel disc 1, its cross section is oval; Its each circle soft magnetism steel disc is surrounded is shaped as rectangle, and four angles of rectangle are fillet.
As Fig. 1, shown in Figure 4,3 one kinds of transformer cores of reeling and forming of embodiment by strip soft magnetism steel disc 1, its cross section is a shape of inserting a rectangle up and down between two semicircles; Its each circle soft magnetism steel disc is surrounded is shaped as rectangle, and four angles of rectangle are fillet.
