Specific embodiment
Embodiment: two conducting wires are mutually welded in intersection
Welded type motor winding terminal portion connecting structure shown in Figure 2, two to extend out out of two winding slot of core lead
Line 1,2 after the circumferential opposite bending of iron core is primary, mutually weld by the end that they intersect.When welding, the end periphery of a conducting wire
It is whole or local mutually welded between the end periphery whole or part of another conducting wire.
Referring to Fig. 3-6, the end 11 of conducting wire 1 is mutually welded with the end 21 of conducting wire 2 in the binding face of iron core diametrically.
Referring to Fig. 7-10, mutually welded between 11 end face of end of conducting wire 1 and 21 side of end of conducting wire 2, meanwhile, conducting wire 2
21 end face of end and 11 side of end of conducting wire 1 between mutually weld.
Referring to Fig. 6,10, to form insulating space 3 between two conducting wires, the end 21 of conducting wire 2 is after radial direction bending
It is mutually welded after radial direction bending with the end of conducting wire 2 end for welding (Fig. 6) or conducting wire 1 with 11 phase of end of conducting wire 1
(Figure 10).
Referring to Figure 11,12,21 end face of end and side of 11 end face of end of conducting wire 1 and a part of side and conducting wire 2
A part between mutually weld.
Referring to Figure 13,14, mutually welded between 11 end face of end of conducting wire 1 and 21 side of end of conducting wire 2, and two conducting wires
Between to form insulating space 3, the end that the end of two conducting wires is intersected after radial direction is bent simultaneously is mutually welded.
When the part for stretching out iron core to conducting wire is turned one's head, conducting wire is stirred in the side of iron core circumferential direction by tooling of turning one's head, is made
The end of conductive line bends to two conducting wires for needing gradient, and connecting needs overlaps, and forms shape as seen in figures 3-6
State passes through electric resistance welding or supersonic welding or other any Welders that can make to form metal connection between two binding faces of conducting wire
Skill welds together two wire terminations.Can certainly use electric welding Laser Welding or other it is any can be by two metals
The welding procedure that the gap of part is welded together welds together the adjacent edges of conducting wire referring to Fig. 7-14, the welding
It can be a solder joint and be also possible to the solder joint above one by one.
Moreover, for Fig. 3-14, when the conducting wire to stretching winding slot of core is turned one's head so that conducting wire is circumferentially bent in iron core
When, it is only necessary to tooling of turning one's head applies external force to side of the conducting wire in iron core circumferential direction.Thus when conducting wire is turned one's head, by
Only one position of conducting wire mutually welded shown in Fig. 3-14 carries out bending (except the bending of conducting wire sloping portion), therefore,
Shaping resistance of turning one's head only has conventional half, and the stress for tooling of turning one's head only has conventional half, so being easier to form and guarantee
Quality.
Embodiment: two conducting wires, two section vertical with winding slot of core mutually weld
Referring to welded type motor winding terminal portion connecting structure shown in Figure 15-18, two to extend out out of two winding slot of core
Root conducting wire 1,2 after the circumferential opposite bending of iron core twice or repeatedly, weld by their wire terminations 11 vertical with winding slot of core, 12 phases
It connects.Two wire terminations 11,12 are parallel to each other in the plane for being parallel to iron core end face.When welding, referring to Figure 16,18, conducting wire 1
End 11 and the end 21 of conducting wire 2 mutually welded in the binding face of iron core diametrically, and the end 21 of conducting wire 2 is in radial direction
It is welded after bending with 11 phase of end of conducting wire 1.By electric resistance welding or supersonic welding or other it is any can make two, conducting wire fitting
The welding procedure that metal connection is formed between face, two wire terminations are welded together.
In this way, compared with the existing technology, the conducting wire in this patent does not need not needing list there are additional retained part yet
Only welding portion parallel with winding slot of core, the structure shorten electric motor winding end size, and conductor length shortens, and both reduce
The resistance of machine winding improves electric efficiency, while reducing the length of machine winding again, have good realistic meaning and
It is advanced.
