Abstract
The utility model provides an iron core of a transformer. The iron core of the transformer comprises an E piece and an I piece. The total length of the E piece and the I piece is 28.2 mm, the total height of the E piece and the I piece is 23.5mm, the tongue width of the iron core is 9.4 mm, the side width of the iron core is 4.7mm, the opening length is 4.7 mm, the height of a window is 14.1mm, and the length of a foot is 18.8mm. The utility model further provides an iron core of a transformer. The iron core of the transformer comprises an E piece and an I piece, The total length of the E piece and the I piece is 35 mm, the total height of the E piece and the I piece is 29.2 mm, the tongue width of the iron core is 11.6 mm, the side width of the iron core is 5.85 mm, the opening length is 5.85 mm, the height of a window is 17.5mm, and the length of a foot is 23.35 mm. A punching piece of the iron core of the transformer is not folded and damaged, and the consumption amount of a varnished wire can be saved by about 30%.
Description
Technical field
The utility model relates to a kind of transformer core.
Background technology
The kind of transformer core has the change of doing iron core, oil to become iron core, core of reactor, orientation iron core, E shaped iron core, EI shaped iron core.Present EI shaped iron core
Overall length is that to be that 25mm or 29.5mm, tongue are wide be 4mm or 5mm, open shelves and be 21mm or 24.5mm for 6mm or 7.7mm, window are high for 17mm or 19.5mm, pin are long for 8mm or 9.6mm, hem width for 28mm or 35mm, height overall.And having lost about 15% of die-cut of existing EI shaped iron core iron core, the enamelled wire consumption is also larger.
The utility model content
Technical problem to be solved in the utility model is the larger problem of losing that solves die-cut of the iron core that exists in the prior art.
The utility model provides a kind of transformer core, comprises E sheet and I sheet, overall length 28.2mm, and height overall 23.5mm, the wide 9.4mm of tongue, hem width 4.7mm opens a grade 4.7mm, the high 14.1mm of window, the long 18.8mm of pin.
The utility model also provides a kind of transformer core, comprises E sheet and I sheet, overall length 35mm, and height overall 29.2mm, the wide 11.6mm of tongue, hem width 5.85mm opens a grade 5.85mm, the high 17.5mm of window, the long 23.35mm of pin.
Die-cut nothing of the utility model transformer core lost, the enamelled wire consumption can be saved about 30%.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the 1st, E sheet, the 2nd, I sheet;
A: overall length, B: height overall, C: tongue is wide, D: hem width, E: open shelves, F: window is high, G: pin is long.
Embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are elaborated.
As shown in Figure 1, the utility model provides two kinds of nonstandard iron cores.
A kind of transformer core comprises E sheet and I sheet, overall length A28.2mm, and height overall B23.5mm, the wide C9.4mm of tongue, hem width D4.7mm opens a grade E4.7mm, the high F14.1mm of window, the long G18.8mm of pin.
Another kind of transformer core comprises E sheet and I sheet, overall length A35mm, and height overall B29.2mm, the wide C11.6mm of tongue, hem width D5.85mm opens a grade E5.85mm, the high F17.5mm of window, the long G23.35mm of pin.
Die-cut nothing of these two kinds of nonstandard iron cores lost, and the enamelled wire consumption can be saved about 30%.
It should be noted last that, above embodiment is only unrestricted for the explanation the technical solution of the utility model, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the claim scope of the present utility model.
