Abstract
The utility model discloses a foil coil winding terminal copper bar, which comprises a copper bar, interlayer insulation, a welding wire and conductive foil materials. The welding wire is arranged on the copper bar, the conductive foil materials are connected with the welding wire, and the interlayer insulation is arranged between adjacent conductive foil materials. The section of the copper bar increases gradually from the lower end to the upper end. The conductive foil materials can be copper foil or aluminum foil. The lower end section of the winding terminal copper bar is smaller than the upper end section, the requirement that current increases in linear mode from bottom to top is met, and simultaneously winding terminal copper bar materials are saved by about 30%, thereby reducing weight of the coil and cost.
Description
Technical field
The utility model relates to the winding protruding head copper bar in a kind of transformer, and specifically a kind of foil coil is lifted one's head copper bar.
Background technology
Foil coil adopts Copper Foil or aluminium foil coiling on special-purpose paper tinsel formula coil winding machine to form, and its structure is similar with the laminar winding, but every layer be a circle, and layer insulation is turn insulation.Elder generation is the Copper Foil (or aluminium foil) and the copper bar firm welding of lifting one's head during the foil coil coiling; Be fixed on and begin coiling on the winding former lifting one's head copper bar then, layer insulation, end insulation and Copper Foil (or aluminium foil) coiling simultaneously, coiling is after the number of turn of regulation; Cut off Copper Foil, weld tail head copper bar and get final product.
The extensive copper bar structure of lifting one's head that adopts of transformer production producer is seen Fig. 2 at present, wherein, the 21st, copper bar, the 22nd, layer insulation, the 23rd, bonding wire, the 24th, conduction foil.This copper bar structure is to select the copper bar of corresponding specification according to the size of coil current, copper bar and Copper Foil (or aluminium foil) axially drawn by the relative position welding is good, and be uniform owing to the electric current that flows through Copper Foil distributes in Copper Foil; Shown in arrow among Fig. 2; So lift one's head in the copper bar electric current to down and on be linear and increase, that is to say that the electric current that the copper bar lower end flows through of lifting one's head is little; The electric current that more upwards flows through is big more, and the copper bar of lifting one's head bears total current in Copper Foil (or aluminium foil) upper end surface.And the cross section of copper bar of lifting one's head of adopting at present is a rectangle, and it is identical with the lower surface promptly to lift one's head the upper surface of copper bar, and this copper bar structure of lifting one's head has increased raw-material use amount, has improved cost of manufacture.
Summary of the invention
To lift one's head the raw material use amount that copper bar exists big in order to overcome existing foil coil, and the problem that cost of manufacture is high, the purpose of the utility model provide a kind of foil coil and lift one's head copper bar, and this foil coil is lifted one's head copper bar and reduced coil weight, has reduced cost; And simple in structure, be easy to processing.
The purpose of the utility model realizes through following technical scheme:
A kind of foil coil is lifted one's head copper bar, comprises copper bar, layer insulation, bonding wire and conduction foil, and bonding wire is arranged on the copper bar, and the conduction foil is connected with bonding wire, between the adjacent conductive foil layer, is provided with layer insulation; It is characterized in that: the cross section of said copper bar is progressively increased to the upper end by the lower end.
In the utility model, said conduction foil can be Copper Foil or aluminium foil.Said copper bar comprises the wire connecting portion on top and the bonding wire connecting portion of lower part, and the wire connecting portion cross section on top is a rectangle, and the bonding wire connecting portion cross section of lower part is the big oblique angle triangle in little upper end, lower end.The cross section of said copper bar is progressively increased to the upper end by the lower end, and with electric current to down and on be linear increase suitable.
The utility model is little according to lifting one's head the electric current that the copper bar lower end flows through, and the electric current that more upwards flows through is big more, and the copper bar of lifting one's head bears circuital characteristics in Copper Foil (or aluminium foil) upper end surface, and the section ratio upper end that is designed to lift one's head the copper bar lower end is smaller.
Compared with prior art, the utility model lift one's head under the copper bar end section little go up end section satisfied greatly electric current to down and on be to be the linear needs that increase; Saved that to lift one's head the copper bar material about 30%, reduced coil weight, reduced cost; And the utility model simple in structure, be easy to processing, get final product by existing technology during coil winding, need not increase new tooling device.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 be adopt at present extensively lift one's head the copper bar structural representation.
Embodiment
The described foil coil of a kind of the utility model is lifted one's head copper bar, sees Fig. 1, and this is lifted one's head copper bar and comprises copper bar 1, layer insulation 2, bonding wire 3 and conduction foil 4, and bonding wire 3 is arranged on the copper bar 1, and conduction foil 4 is connected with bonding wire 3, and the foil 4 that conducts electricity can be Copper Foil or aluminium foil.Be provided with layer insulation 2 at adjacent conductive foil 4 interlayers; The cross section of copper bar 1 is progressively increased to the upper end by the lower end.Copper bar 1 comprises the wire connecting portion 11 on top and the bonding wire connecting portion 12 of lower part, and wire connecting portion 11 cross sections on top are rectangle, and the top and bottom in cross section are equally big; Bonding wire connecting portion 12 cross sections of lower part are the big oblique angle triangle in little upper end, lower end, and the cross section of copper bar is progressively increased to the upper end by the lower end, and with electric current to down and on be linear increase suitable.
The little end section that goes up of end section is big under the utility model, satisfy electric current to down and on saved that to lift one's head the copper bar material about 30% when being to be the linear needs that increase, reduced coil weight, reduced cost.
