Abstract
The invention discloses a conductor overlap welding end socket, which comprises a conductor, wherein the specification of the conductor is a*b, the thickness direction of a conductor endpoint is in a single arc shape with the radius r, the width direction is in a double-arc shape with the radius R, wherein r=a, and R=b/2. The conductor overlap welding end socket disclosed by the invention has a reasonable process structure, the welding quality of a coil tends to be stable, the short circuit resistance capacity of the coil is improved, and local discharge of a product is reduced.
Description
Technical field
The present invention relates to a kind of wire bonds and process, relate in particular to the wire bonds termination.
Background technology
Transformer coil is the core of transformer circuit part, in order to guarantee the reliability service of transformer, it should use under nominal working conditions for a long time, be able to take again the effect such as overcurrent, overvoltage and the corresponding electromagnetic force of the generations such as short circuit, thunderbolt, switching manipulation, unlikely generation insulation breakdown, overheated, distortion or destroy, so coil is as the parts of the most critical of transformer, it should have enough dielectric strengths, mechanical strength, temperature capacity and good radiating condition.To carry out wire bonds in the coil winding process, wire bonds is mainly used in the wire gauge change, interleaved coil is entangled with unit wire bonds, the full transposition of compound wire self etc., the quality of wire bonds has a strong impact on mass of coil, if wire bonds is insecure, may cause wire break, resistance bigger than normal, degradation quality problems under the anti-short circuit capability, the termination is processed not thorough, can cause partial discharge.
Summary of the invention
Technical problem to be solved by this invention is the partial discharge problem for wire bonds place in the prior art.
For solving this technical problem, the invention provides a kind of wire overlap welding termination, comprise wire, this wire gauge is a * b, and the thickness direction of described wire end points is the single-arc shaped of radius r, and Width is two arcs of radius R, r=a wherein, R=b/2.
Beneficial effect: process structure of the present invention is reasonable, and the coil welding quality is tended towards stability, and has improved the coil anti-short circuit capability, reduces the product partial discharge.
Description of drawings
Fig. 1 is structural representation front view of the present invention;
Fig. 2 is structural representation vertical view of the present invention;
Fig. 3 is Welding Structure schematic diagram of the present invention.
Among the figure: 1 wire.
Embodiment
Below in conjunction with drawings and Examples the present invention is done specific descriptions.
Figure 1 shows that structural representation front view of the present invention.
Figure 2 shows that structural representation vertical view of the present invention.
The present invention includes wire 1, this wire gauge is a * b, and wherein a is the thickness of wire; B is the width of wire.
The thickness direction of described wire end points is the single-arc shaped of radius r, and Width is two arcs of radius R, r=a wherein, R=b/2.
The present invention realizes by following steps: the wire bonds termination divests insulation: 40～60mm; Conducting wire end is repaiied the file unidirectional circular arc of r=a (as shown in Figure 1); Conducting wire end is cut into R=b/2(as shown in Figure 2 with specific purpose tool with the termination).
Adopt welding procedure of the present invention:
Wire overlap joint: the wire lap of splice is L=(1～1.5) b(as shown in Figure 3).
Welding: compress wire and determine the welding position with welding gun, weld tabs is put between wire, start hold-down cylinder and compress wire,
Start arc welding gun switch and weld, trip switch after weld tabs melts after the ruddiness on the wire disappears by the time, is unclamped hold-down cylinder, is taken away welding gun.
After welding treatment: remove overlap, burr and the wedge angle of weld with file, the emery cloth sanding; Weld is cleaned out, removed the insulating barrier of carbonization; Place the insulating board with the 0.5mm thickness of the width such as wire in the solder joint top and bottom, wrap up to specific thickness with the crimped paper half lap again; With tooth spectroscopy wire sealing run, become fillet around the weld seam, without any wedge angle point, guarantee that welding is well.
Process structure of the present invention is reasonable, and the coil welding quality is tended towards stability, and has improved the coil anti-short circuit capability, reduces the product partial discharge.
The above-mentioned embodiment of the present invention just illustrates, and is not only, all within the scope of the present invention or the change that is equal in the scope of the present invention all surrounded by the present invention.
Claims (1)
1. a wire overlap welding termination comprises wire, and this wire gauge is a * b, it is characterized in that: the thickness direction of described wire end points is the single-arc shaped of radius r, and Width is two arcs of radius R, r=a wherein, R=b/2.
