Abstract
The utility model relates to a lead structure of a transformer foil-type winding, which comprises a coil (1), a copper foil (2) and a copper bar (3), wherein the copper bar (3) is welded with the copper foil (2), and a welding surface (3.1) between the copper bar (3) and the copper foil (2) is a right triangle. After adopting the structure, the welding surface between the copper bar and the copper foil is the right triangle, thus reducing the size of the welding surface between the copper bar and the copper foil, and further decreasing the copper consumption of the copper bar, saving materials and reducing the cost.
Description
Technical field:
The utility model relates to the power transformer field, specifically is a kind of pin configuration of transformer foil formula winding.
Background technology:
In the prior art, the lead end of transformer foil formula winding adopts copper bar to weld out header structure, generally is the Copper Foil welding of adopting whole copper bar and paper tinsel formula winding leads end, and solder side covers the Copper Foil of whole lead end, and the copper material consumption is big, waste material, and cost is higher.
The utility model content:
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, provides a kind of economical with materials, the pin configuration of lower-cost transformer foil formula winding.
Technical solution of the present utility model is, a kind of pin configuration of transformer foil formula winding is provided, and it comprises coiling, Copper Foil, copper bar, described copper bar and Copper Foil welding, and described copper bar is a right-angled triangle with the solder side that Copper Foil welds.
After adopting said structure, the utlity model has following advantage:
The solder side of copper bar and Copper Foil is a right-angled triangle, has reduced the size of copper bar and Copper Foil solder side, thereby the amount of copper consuming of copper bar is reduced, economical with materials, and cost reduces.
As improvement, the length of the long right-angle side of described right-angled triangle is half of coil lead end Copper Foil length, adopts this structure, when the processing copper bar, can process two copper bars simultaneously, has so both saved material, and processing is convenient again.
Description of drawings:
Accompanying drawing 1 is the structural representation of the pin configuration of the utility model transformer foil formula winding;
Accompanying drawing 2 is schematic diagrames that copper bar takes off 180 ° of back upsets among Fig. 1;
Accompanying drawing 3 is a kind of improved structural representations of the pin configuration of the utility model transformer foil formula winding.
As shown in the figure: 1, coil, 2, Copper Foil, 3, copper bar, 3.1, solder side.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the pin configuration of the utility model transformer foil formula winding, it comprises coiling 1, Copper Foil 2, copper bar 3, described copper bar 3 is right-angled triangle with Copper Foil 2 welding, described copper bar 3 with the solder side 3.1 of Copper Foil 2 welding.
As improvement, as shown in Figure 3, the length of the long right-angle side of described right-angled triangle is half of coil 1 lead end Copper Foil 2 length, promptly shown in the area size of right-angled triangle be half of area of coil 1 lead end Copper Foil 2.
After adopting said structure, the solder side of copper bar and Copper Foil is a right-angled triangle, has reduced the size of copper bar and Copper Foil solder side, promptly can reduce the size of copper bar, thereby the amount of copper consuming of copper bar is reduced, economical with materials, and cost reduces.
Claims (2)
1. the pin configuration of a transformer foil formula winding, it comprises coiling (1), Copper Foil (2), copper bar (3), described copper bar (3) and Copper Foil (2) welding is characterized in that: described copper bar (3) is a right-angled triangle with the solder side (3.1) of Copper Foil (2) welding.
2. the pin configuration of transformer foil formula winding according to claim 1 is characterized in that: the length of the long right-angle side of described right-angled triangle is half of coil (1) lead end Copper Foil (2) length.
