[0020] The special-shaped insulated wire provided by the utility model is explained and illustrated in detail below in conjunction with the drawings of the specification.

[0021] This embodiment specifically discloses a special-shaped insulated wire, such as Figure 1 As shown, it includes a conductor 1 and an insulating layer 2 covering the outer surface of the conductor 1, such as Figure 1 and 2As shown, the cross section of the conductor 1 is flat D-shaped, including a straight segment 11, a first arc segment 12 above the straight segment 11, and a second arc segment 13 connecting the ends of the straight segment 11 and the first arc segment 12 on the same side. The lengths of the straight segment 11 and the first arc segment 12 can be set according to the use occasion and specific requirements, the first arc segment 12 is a circular arc or an elliptical arc, and the second arc segment 13 is a circular arc or an elliptical arc. The shapes of the first arc segment 12 and the second arc segment 13 can also be set according to the use occasion and specific requirements to meet the needs of different occasions.

[0022] like Figure 2 As shown, the radius R1 of the first arc segment 12 is the same as the straight line length B between the two end points of the first arc segment 12. The straight line length B between the two end points of the first arc segment 12 is the same as the length of the first straight line segment 11, that is, the two ends of the first arc segment 12 are respectively aligned with the two ends of the first straight line segment 11. The relationship between the straight line length B between the two end points of the first arc segment 12 and the vertical distance t from the highest point of the first arc segment 12 to the straight line segment 11 is: 4≤B / t≤15, which defines the length-to-height ratio of the special-shaped insulated wire, and the specific size can be adjusted within this range according to the use occasion and specific requirements.

[0023] The relationship between the radius R2 of the second arc segment 13 and the vertical distance t from the highest point of the first arc segment 12 to the straight segment 11 is: t / 4≤R2<t / 2, which limits the shape and size of the second arc segment 13. The shape and size of the second arc segment 13 can also be adjusted within this range according to the application scenario and specific requirements.

[0024] Figure 2 The conductor 1 of the cross-sectional shape shown is smaller in volume and weight than a rectangular structure of the same length and height and a circular structure of the same length (the length of the conductor 1 in this embodiment is taken as the diameter of the circular structure), and has faster heat dissipation. The length of the conductor 1 refers to the distance between the highest points of the arcs of the two second arc segments 13, and the height of the conductor is the vertical distance t from the highest point of the first arc segment 12 to the straight segment 11. Moreover, the small cross-section and high resistance make it have excellent electromagnetic compatibility, which can effectively reduce the generation of interfering electromagnetic waves and the interference to the surrounding environment. At the same time, the flat structure is also convenient for winding, making the weight and volume of the electrical components smaller, which not only ensures the contact area between the wires during winding, but also ensures the heat dissipation performance.

[0025] In some embodiments, the conductor 1 is any one of gold, silver, copper and their alloys, that is, the conductor 1 is gold, silver, copper, gold alloy, silver alloy or copper alloy. The insulating layer 2 is an insulating paint film, and the insulating layer 2 is a polyurethane layer (PU), a polyetherimide layer (PEI), a polyimide layer (PI), a polyamide-imide layer (PAI), a polyetheretherketone layer (PEEK) or a thermoplastic polyimide layer (TPI). It adopts an organic paint with excellent high temperature and pressure resistance, good anti-leakage and durability, and good heat resistance and chemical resistance. And it has good self-adhesion, which helps to improve the tightness between the stacked special-shaped insulated wires, thereby improving the performance of the coil formed by the stacked winding of the special-shaped insulated wires. The cross-sectional shape design of the conductor 1 can satisfy the uniform coating of the paint liquid to form an insulating paint film.

[0026] The method for manufacturing the special-shaped insulated wire in the embodiment of the present application is as follows: 1. The conductor 1 is formed by rolling and passing through a mold. Figure 2 2. After the bare wire is formed, the insulating layer 2 is coated to obtain Figure 1 Special-shaped insulated wire shown.

[0027] The special-shaped insulated wires of the embodiments of the present application can be used in the ship field for the circuit winding of electrical components such as the ship's main engine, auxiliary engine, auxiliary equipment and navigation instruments; in the aerospace field for the winding of engine coils and control systems; in the power field for the circuit winding of various electrical components. The shape and size of the special-shaped insulated wires can be designed within the above range according to the use environment and specific requirements, and can meet the needs of different occasions.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and simple improvement made to the essential content of the present invention shall be included in the protection scope of the present invention.
