Abstract
The utility model discloses a kind of notched transformer coil outlet structure, comprise lead division, kink and connecting portion, described kink two ends connect lead division and connecting portion respectively, and described kink and connecting portion are made up of multilayer copper foil; Lead division bottom is set to the arcwall face with the radian fitted with coil simultaneously, and offers breach.Kink of the present utility model and connecting portion are made up of multilayer copper foil, Copper Foil be easy to bending, solve the unpliant problem of traditional copper bar, by the bending of kink, can reduce outlet structure beyond coil part take up room, make its scope of application wider; Meanwhile, lead division and coil fit, and ensure meet the coil shape rule that coiling goes out technique for coiling and make current density be in OK range; Lead division arranges breach can save material usage, reduces costs.
Description
Technical field
The utility model relates to field transformer, particularly relates to the outlet structure of transformer coil.
Background technology
Traditional transformer coil outlet row, by copper bar bending and forming, because copper bar not easily bends, makes the part beyond coil occupy very large space, when space is restricted, cannot adopt this kind of outlet row.
In addition, traditional outlet row is owing to not easily bending, and be not bent into the radian of fitting with coil with coil welding portion, the coil shape causing coiling to go out is irregular.Meanwhile, traditional outlet row directly superposes welding with coiling or paillon foil, and its cross section increases, and current density reduces, and causes waste of material.
Utility model content
Therefore, in order to solve the problems of the technologies described above, the utility model provides a kind of outlet structure of novel transformer coil.
The technical scheme that the utility model adopts is:
A kind of notched transformer coil outlet structure, comprise lead division, kink and connecting portion, described kink two ends connect lead division and connecting portion respectively, described kink and connecting portion are made up of multilayer copper foil, described lead division is set to the arcwall face with the radian fitted with coil, and lead division offers breach.
As the further improvement of technique scheme, described lead division is made up of multilayer copper foil, and lead division, kink and connecting portion are wholely set.
As the further improvement of technique scheme, described lead division also can be made up of copper bar, and lead division welds mutually with kink.
As the further improvement of technique scheme, described connecting portion is provided with through hole, through hole is used for bolt combination connecting lead wire copper bar.
The beneficial effects of the utility model are:
Kink of the present utility model and connecting portion are made up of multilayer copper foil, Copper Foil be easy to bending, solve the unpliant problem of traditional copper bar, by the bending of kink, can reduce outlet structure beyond coil part take up room, make its scope of application wider; Meanwhile, lead division and coil fit, and ensure meet the coil shape rule that coiling goes out technique for coiling and make current density be in OK range; Lead division arranges breach can save material usage, reduces costs.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model first embodiment;
Fig. 2 is the structural representation of the utility model second embodiment.
Drawing reference numeral illustrates: 1 (1 '), lead division; 2, kink; 3, connecting portion; 4, through hole; 5, breach.
Embodiment
As the embodiment one that Fig. 1 provides for the utility model, a kind of notched transformer coil outlet structure, comprises lead division 1, kink 2 and connecting portion 3, and lead division 1 is positioned at coil and welds with coiling paillon foil, and kink 2 and connecting portion 3 are positioned at outside coil.In the present embodiment, lead division 1, kink 2 and connecting portion 3 are wholely set, and are made up of multilayer copper foil.Be positioned at kink 2 outside coil and connecting portion 3 is Copper Foil, be easy to bending, outlet structure the taking up room of part beyond coil can be reduced, and when being connected with lead-in wire copper bar, a buffering area can be formed herein.Lead division 1 for welding with coil is set to the arcwall face with the radian fitted with coil, and offer breach 5, the degree of depth of breach 5 is preferably the half of lead division 1 width, but this can increase or reduce, guarantee that the welding position of coiling paillon foil and lead division 1 is enough and superpose cross section to flow through current density suitable.Connecting portion 3 is provided with through hole 4, through hole 4 for bolt combination connecting lead wire copper bar, when connecting portion 3 and lead-in wire copper bar adopt be welded to connect time, also can cancel through hole 4.
As the embodiment two that Fig. 2 provides for the utility model, comprise lead division 1 ', kink 2 and connecting portion 3, lead division 1 ' is made up of copper bar, kink 2 and connecting portion 3 are all made up of multilayer copper foil, lead division 1 ' and kink 2 weld mutually, lead division 1 ' is bent into the arcwall face fitted with coil, and offers breach 5, and connecting portion 3 is also provided with through hole 4.
Above concrete structure and sized data illustrate preferred embodiment of the present utility model, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
