Technical field

The utility model relates to a kind of transformer E core lamination.

Background technology

At present, known miniature transformer E sections core is to have E type lamination and I type lamination stack system to form.The Sheet Metal Forming Technology comparative maturity of I type lamination wherein, and the low problem of Sheet Metal Forming Technology ubiquity stock utilization of E type lamination.According to the difference along flanging between limit flanging, workpiece and structural waste material sum in the E type lamination blanking sample layout, the stock utilization of miniature transformer E sections core lamination is between 60.4%～75.8%.

The utility model content

The purpose of this utility model is the low problem of stock utilization at miniature transformer E sections core, provides a kind of stock utilization high miniature transformer E sections core lamination.

For achieving the above object, the utility model adopts following technical scheme: miniature transformer E sections core lamination, it is made up of a U type lamination, the 2nd U type lamination and I type lamination, wherein one side combination at grade of one side of a U type lamination and the 2nd U type lamination, form E type lamination, the end combinations of holding, the open side of sealing described E type lamination are erected with two of the described E type lamination outside respectively in the two ends of I type lamination.

Further, two perpendicular ends of the one U type lamination are a long limit and a minor face, two perpendicular ends of the 2nd U type lamination also are a long limit and a minor face, the minor face combination at grade of the minor face of the one U type lamination and the 2nd U type lamination, form E type lamination, the two ends of I type lamination respectively with the end combination on the long limit of described E type lamination, the open side of sealing described E type lamination.

As a kind of execution mode of the present utility model, the width of the perpendicular end of a U type lamination one is identical with distance between the 2nd U type lamination two perpendicular end medial surfaces, and it is identical that the width of the 2nd U type lamination one perpendicular end and a U type lamination two erect the distance of holding between the medial surfaces.

As another kind of execution mode of the present utility model, the width of a U type lamination one perpendicular end is less than the distance between the 2nd U type lamination two perpendicular end medial surfaces, and the width of the 2nd U type lamination one perpendicular end is less than the distance between a U type lamination two perpendicular end medial surfaces.

The beneficial effects of the utility model are that the combination by a U type lamination, the 2nd U type lamination and I type lamination has improved stock utilization, has reduced waste material.
