Specific embodiment

Illustrate this practical invention with reference to the accompanying drawing.

Referring to Fig. 1, the coil is existing loop construction schematic diagram, conducting wire is wrapped on plug by coil winding machine, Then plug is extracted out, coil completes, and there are an obvious drawbacks for existing coil, that is, after plug detaches, coil 1 The position of upper original plug can leave a gap 11, since micro motor is sufficiently thin, therefore it is required that coil is also thin enough, also Have, the conducting wire of micro motor is extremely fine, so plug cannot be too thin, the thickness of plug will not generally be less than 0.5mm at present, and micro- The arrangement body thickness of type motor coil also 2.5mm.Therefore the former plug space 11 on coil 1 cannot make full use of, coil Magnetism it is related with winding the number of turns of conducting wire, winding the number of turns it is more, magnetism it is stronger, if the plug space is made full use of, not Change is existing will to increase winding the number of turns of conducting wire in the case of altitude, increases its magnetism.

Referring to Fig. 2, extrusion forming is carried out to coil 1 if to make full use of former plug space 11, then, coil squeezes Former plug space 11 can be to upper and lower two sides extension 12 after pressure, and therefore, the conducting wire in coil just becomes irregular, and insulating layer is weak Place generates the case where puncture short.

Its process further comprises:

A1: providing plug, and the section of the plug is thin ends and thick middle；

A2: conducting wire is wound on plug by coil winding machine；To wire-heated while winding, make the insulating layer of conducting wire Softening, the insulating layer after softening, can mutual adhesions in winding process under the premise of not being destroyed；

A3: after the completion of winding, plug is separated with coil；

A4: being finally put into extrusion forming in jig for the coil after separation, the plug position profile after molding, on primary coil Thin ends and thick middle space is extruded, and seamless unoccupied place adhesion between the coil after being extruded.

Being wound into conducting wire on plug further by coil winding machine includes: repeatedly to wind conducting wire, and plug winding Height is greater than the height being required in advance；It further includes: line after being extruded that plug locational space on primary coil, which is extruded, Circle height is in the height being required in advance.The present invention provides pressing steps, so that the open ended coil winding of identical height The number of turns greatly promotes, and then increases its magnetism.

In general, the thickness of the plug of the coil will not be less than 1mm, and coil integral thickness after extruding is not higher than 3mm.The thin ends and thick middle space of plug position profile on primary coil is squeezed into threadiness.It is thick among the section of the plug Both ends are thin, and the thin ends and thick middle space of the plug position profile on primary coil is extruded, and between the coil after being extruded Seamless unoccupied place adhesion is not present space waste, greatly improves the utilization rate in space.

Fig. 3-7 is please referred to, the present invention is illustrated so that coil height is 2.5mm as an example.

According to coil design requirements, coil finished product height is 2.5mm, since plug 21 is with a thickness of 0.5mm, according to coil The height of sub- finished product is 2.5mm, and during coil extrusion forming, coil can extend around, therefore, according to its finished product face Product calculates, and coil winding height is 3.0mm, and conducting wire 13 is wound on the plug 21 that section is olive-type on coil winding machine 2, Conducting wire 13 is heated in the winding process of conducting wire, which is that guiding line blows hot wind, makes the exhausted of conducting wire 13 Edge layer softens, and in the winding process of conducting wire 13, sticks together between conducting wire and conducting wire, and according to design requirement, coil is twined To reach 3.0mm around thickness, after reaching winding requirement, existing coil 1 is separated from plug 21, the space after the plug 21 separation Then coil 1 is put into the shaping area 311 of the first jig 31 for olive shape space 13, the second jig 32 pushes, and is being squeezed into Position-limiting action is played when type, then, outside of the third jig 33 by shaping area 311, ecto-entad extruding, first, second, third It is heating plate that jig, which carries heating device or jig itself, and air port 312 can also be arranged on jig, past by air port 312 Hot wind is sent in shaping area 311, also can achieve the effect of softening wire insulation, during extrusion forming, due to jig With heating function, therefore, the insulating layer of coil 1 can soften, it is easier to form, when third jig 33 is expressed to coil When subscribing 2.5mm, stop squeezing, at this moment former olive shape plug space 13 is squeezed completely, finished product coil 5 after molding, due to, Plug section of the invention is olive-type, therefore it, is not in such as attached drawing 2 during extrusion forming that intermediate high two sides are low On the distorting event that occurs of coil, the conductor adhesion up and down in original olive shape plug space 13 after extruding, is in a straight line, up and down There is no gap between conducting wire.

The smelting tool of generation can be buying existing smelting tool, can also be independent newly developed, it is only necessary to achieve the effect that it is above-mentioned, Protection scope of the present invention should all be fallen into.

A kind of structure of motor coil, including coil body, the thin ends and thick middle space quilt in plug position on coil It squeezes, and seamless unoccupied place adhesion between the coil after being extruded.The thin ends and thick middle space in plug position on primary coil It is squeezed into threadiness.Coil integral thickness after being extruded is not higher than 3mm.Referring to Fig. 6, the figure is that this coil is applied to certain production Demonstration example in product, the finished product coil 5 after extrusion forming are assembled into motor case 4, are equipped between shell 4 and finished product coil 5 Magnet 41 is equipped with rotor 42 between two finished product coils.Our experiments show that corresponding motor performance has obtained good promotion.

So this practical invention is disclosed as above with embodiment, and so it is not limited to this practical invention, any affiliated neck Has usually intellectual in domain, in the spirit and scope for not departing from this practical invention, when can make some changes and embellishment, all Answer the protection scope of this practical invention.
