The utility model adopts the technical proposal that:

the utility model provides a hollow wire winding coil of toper, includes by interior to be a plurality of coil layers that the echelonment was arranged outside, a plurality of coil layer bottom aligns, and the coil appearance that a plurality of coil layers are constituteed is roughly the toper, and a plurality of coil layers are by single wire winding by interior to outside coiling in proper order and form.

Furthermore, the coil layer is four layers, namely a first coil layer, a second coil layer, a third coil layer and a fourth coil layer.

Furthermore, the first coil layer, the second coil layer, the third coil layer and the fourth coil layer are all in a hollow cylinder shape.

Furthermore, the winding wire end at the top of the second coil layer is obtained by pulling the winding wire end at the top of the first coil layer downwards through a certain angle along the winding direction.

Furthermore, the winding end at the top of the fourth coil layer is obtained by pulling the winding end at the top of the third coil layer downwards through a certain angle along the winding direction.

Further, the winding is a self-adhesive wire.

The utility model has the advantages that:

the multi-layer stepped coil is wound by adopting a single winding, so that each step forms a cone from top to bottom, the flowing of the potting material is facilitated when the shell is potted, no gap or bubble is formed in the gap, the potting quality is improved, and the problems that the top and the bottom of the cylindrical hollow coil are the same in size, the bubble in the potting gap is easily caused, and the product quality is influenced are solved;

the whole coil is wound by a single winding, the appearance is smooth and distinct, the performance is stable, and the fluctuation of product difference is small;

and self-adhesive wires are adopted for winding, so that the full-automatic winding machine is suitable for full-automatic winding, and the production difficulty is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-4, the present invention provides a tapered hollow winding coil, which comprises a plurality of coil layers arranged in a step shape from inside to outside, wherein the bottoms of the plurality of coil layers are aligned, the shape of the coil formed by the plurality of coil layers is substantially tapered, and the plurality of coil layers are formed by sequentially winding a self-adhesive wire from inside to outside; because the steps are arranged between the two adjacent coil layers, the connecting line of each step from top to bottom forms a cone, and when potting materials enter, the filling materials can be rapidly and uniformly distributed in the shell and are filled in the gap between the coil and the shell.

Specifically, the coil layer is four layers, namely a first coil layer 1, a second coil layer 2, a third coil layer 3 and a fourth coil layer 4; the first coil layer 1, the second coil layer 2, the third coil layer 3 and the fourth coil layer 4 are all hollow cylinders; first coil layer 1, second coil layer 2, third coil layer 3 and fourth coil layer 4 bottom flush, the toper coil bottom of constituteing is thickest, stability is best, between 2 tops on second coil layer and the 1 top on first coil layer, between 3 tops on third coil layer and the 2 layers of tops on second coil layer, the distance between 4 tops on fourth coil layer and the 3 layers of tops on third coil layer equals, make each step height equal, the encapsulating material distributes more evenly.

Furthermore, the winding end at the top of the layer 2 of the second coil is obtained by pulling the winding end at the top of the layer 1 of the first coil downwards along the winding direction by a certain angle; the winding end at the top of the 4 layers of the fourth coil is obtained by pulling the winding end at the top of the third coil layer 3 downwards along the winding direction by a certain angle;

the specific winding process of the conical coil is as follows:

during winding, the self-adhesive wire is tightly wound on the cylindrical first coil layer 1 from bottom to top;

after the first coil layer 1 is wound, a thread end at the top of the first coil layer is pulled downwards from the top by a certain angle along the winding direction, a certain distance is reserved between the thread end and the top of the first coil layer 1, and then a cylindrical second coil layer 2 is wound tightly;

the second coil layer 2 is wound until the bottom of the second coil layer is flush with the bottom of the first coil layer 1;

from the end of winding the second coil layer 2, a cylindrical third coil layer 3 is tightly wound from bottom to top until the end of winding the third coil layer 3, and a step is formed between the top of the third coil layer 3 and the top of the second coil layer 2;

the end of a thread at the top of the third coil layer 3 is pulled downwards from the top of the third coil layer by a certain angle along the winding direction, a certain distance is reserved between the end of the thread and the top of the third coil layer 3, and then the cylindrical fourth coil layer 4 is tightly wound until the bottom of the fourth coil layer 4 is flush with the bottoms of the first coil layer 1 and the second coil layer 2.

If more layers are needed, the conical hollow winding coils are formed by winding in sequence according to the mode.

According to the method, the multilayer stepped coil is wound by adopting a single winding, so that each step cluster forms a cone shape from top to bottom, the pouring of the potting material is facilitated when the shell is potted, gaps and bubbles are not formed in the gaps, the potting quality is improved, and the problems that the top and the bottom of the cylindrical hollow coil are the same in size, the potting gaps are easily caused, and the product quality is influenced are solved; the whole coil is wound by a single winding, the appearance is smooth and well-arranged, the performance is stable, and the fluctuation of product difference is small.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
