Abstract
The invention discloses a pouring-type transformer wire wound low-voltage coil leading-out head structure. The structure comprises a coil and epoxy resin, a starting end copper bar and a terminal end copper bar, wherein the starting end copper bar is welded with a wire starting end of the coil; the terminal end copper bar is welded with a wire terminal end of the coil; and the epoxy resin is poured on the peripheries of the starting end copper bar and the terminal end copper bar. By using the pouring-type transformer wire wound low-voltage coil leading-out head structure, the problem that an insulation wrap treatment is troublesome, the insulation distance is difficult to control and a fault is easy to cause because the wire wound low-voltage coil in the prior art has the leading-out head structure led out from the wire directly is solved; and by welding the starting end copper bar and the terminal end copper bar when the coil is wound, and molding by pouring in vacuum along with a mould, the leading-out part of the coil has high consistency, high insulating intensity and high reliability, and a drying process after assembling does not need to be performed, so that the cost is saved.
Description
Technical field
The present invention relates to a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure, belonged to the transformer technology field.
Background technology
At present, when producing transformer, for low-voltage coil that can not or be inconvenient to use the foil coiling; All adopt the wire rod coiling; As shown in Figure 1, all be the leading-out end structure that adopts this line 7 directly to draw with the low-voltage coil of wire rod coiling, welding lead terminal board externally after the assembling.This leading-out end structure outward appearance is comparatively ugly, and also trouble is handled in the insulation wrapping, and insulation distance also is difficult to control, breaks down easily.Protection during welding, cooling measure are also more hard to manage, the coil epoxy is burnt or ftracture, and welding slag or other foreign matters are fallen into also not easy to clean.Go damp drying also pretty troublesome after the welding.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure, makes that the low-voltage coil of wire rod coiling is specious, and technology is simple and safe and reliable, and is also cost-saved.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure; Comprise coil, epoxy resin, also comprise the copper bar of starting, an end copper bar, the said copper bar of starting rises around head with the wire rod of said coil and welds mutually; A said end copper bar welds with the wire rod end head of said coil mutually, and said poured with epoxy resin is in the periphery of said start a copper bar and an end copper bar.
Aforesaid a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure, it is characterized in that: said wire rod is started and before coil winding, is welded mutually with the said copper bar of starting.
Aforesaid a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure is characterized in that: said wire rod end head adopts quarter bend to draw the back and welds mutually with a said end copper bar.
Aforesaid a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure is characterized in that: the said copper bar of starting is in aggregates with an end copper bar and coil cast.
The invention has the beneficial effects as follows:
Just will rise during 1, through coil winding, an end copper bar weld, and with mould vacuum pouring moulding, makes the high conformity at winding protruding head position, dielectric strength is high, sound construction, good looking appearance, technology is simple, safety, reliability height.
2, the coil itself before the cast just needs dried, thereby through adopting above technical scheme, the drying process after need not assembling has been practiced thrift cost, has shortened the production duration.

Fig. 2 is a cast-type wire rod coiling low-voltage coil structural representation of the present invention;
Fig. 3 is a cast-type wire rod coiling low-voltage coil leading-out end part-structure sketch map of the present invention.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figures 2 and 3, a kind of cast-type transformer wire coiling low-voltage coil leading-out end structure comprises coil 6, epoxy resin 3; Also comprise the copper bar 1 of starting, an end copper bar 2, make corresponding die cavity, and the position of on core rod, starting mills certain thickness (thickness by the copper bar 1 of starting is fixed) at the leading-out end position of mould; Be used for placing the copper bar 1 of starting; Wire rod rise around 4 with start copper bar 1 welding and bandaging, filled up grid, then coiling 6 on request.After coil 6 coilings are good; Draw at the wire rod of coil 6 end 5, welds with an end copper bar 2, and end head insulation wrapping and reinforced insulation are separated; The coil of handling well is adorned mould, preliminary drying drying, vacuum pouring, curing, the demoulding; Come out the rising of coil, end head of the demoulding is copper bar and draws, and carries out the copper bar connection on request during follow-up assembling and gets final product operations such as the welding after need not assembling, drying.
The wire rod of coil 6 is started and 4 before coil winding, is welded with the copper bar 1 of starting, and wire rod is started 4 contact more fully with the copper bar 1 of starting, and insulation processing is more convenient, reliable.
Last 5 in the wire rod of coil 6 adopts quarter bends to draw the back and welds with an end copper bar 2, and it is more abundant that last 5 in wire rod is contacted with an end copper bar 2, and insulation processing is more convenient, reliable.
In sum; A kind of cast-type transformer wire coiling low-voltage coil leading-out end structure provided by the invention; Just will rise during through coil winding, an end copper bar weld, and with mould vacuum pouring moulding, makes that high conformity, dielectric strength height, the reliability at winding protruding head position are high; Drying process after need not assembling has been practiced thrift cost.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range by appending claims and equivalent circle thereof.
