CN203456247U - Novel copper bar winding - Google Patents

Abstract

The utility model relates to a novel copper bar winding. The novel copper bar winding comprises a copper bar, and is characterized in that the copper bar is a downward multi-section bent copper bar after expansion, the copper bar is wound into a cylinder, the upper surface and the lower surface are flush, a cushion block is arranged between every two turns of the copper bar, the cushion blocks are connected through stays, and a winding tap is guided out of the copper bar. After the whole copper bar is wound, the appearance is aesthetic, the processability in manufacturing is good, heat dissipation conditions are good, the mechanical strength is high, the material cost is saved, a sheathing process is simple and the welding of a lead is not required.

Description

Novel copper bar winding

Technical field

The utility model belongs to the low voltage heavy current transformer winding for the heating of various industrial treatment stoves, particularly a kind of Novel copper bar winding.

Background technology

Existing low voltage heavy current transformer winding, all the two cake formula structures that adopt multiple conducting wires coiling, between each two cake, parallel connection is welded on same copper bar, welding procedure is complicated, easily produce defect, cause between cake short circuit or open circuit, whole transformer profile is not attractive in appearance yet simultaneously, and transformer material consumption is also many.

Summary of the invention

The purpose of this utility model will solve the problems referred to above that prior art exists, and provides a kind of anufacturability good, and transformer material consumption is few, the Novel copper bar winding of good looking appearance.

The utility model is achieved in that

A Novel copper bar winding, has a copper bar, and its special character is: after described copper bar launches, be downward multistage bending-like, it is concordant that copper bar turns to cylindric and upper and lower surface, between every two circle copper bars, cushion block is set, between cushion block, by stay, connects, at copper bar up-drawing, go out Winding tap.

The beneficial effects of the utility model are: after whole copper bar coiling, and good looking appearance, anufacturability is good, and radiating condition is good, and mechanical strength is high, saves material cost, and suit technique is simple, does not need wire bonds.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that copper bar launches schematic diagram.

Embodiment

This Novel copper bar winding, has a copper bar 1, after described copper bar 1 launches, is multistage downward bending shape, after copper bar 1 coiling, upper and lower surface is concordant, between every two circle copper bars 1, cushion block 2 is set, between cushion block 2, by the stay 3 penetrating, connects, at the two ends of copper bar a, x, draw Winding tap 4.

Claims (1)

1. a Novel copper bar winding, has a copper bar, it is characterized in that: after described copper bar launches, be downward multistage bending-like, it is concordant that copper bar turns to cylindric and upper and lower surface, between every two circle copper bars, cushion block is set, between cushion block, by stay, connects, at copper bar up-drawing, go out Winding tap.
