The gap filling body 2 and the encapsulation skin layer 1 are integrally formed. The encapsulation skin layer 1 is an insulation layer. The Litz wire combination is at least two Litz wire bodies 3 twisted with each other. Each of the Litz wire bodies 3 is a structure in which a plurality of wire cores 5 are twisted into one body.

[0026] In some specific embodiments, as shown in Figure 3 , the Litz wire combination is two Litz wire bodies 3 twisted with each other. The two Litz wire bodies 3 twisted with each other are one embodiment. The Litz wire combination can also be more than two Litz wire bodies 3 twisted with each other, such as three or four Litz wire bodies 3 twisted into a Litz wire combination.

[0027] Specifically, the plurality of Litz wire bodies 3 twisted with each other are structures obtained by uniformly twisting through a twisting machine according to a preset twisting density.

[0028] Specifically, the gap filling body 2 and the encapsulation skin layer 1 are a seamless encapsulation structure formed by extrusion hot pressing or a heat-shrinkable sleeve composite. The seamless encapsulation structure wraps the side surface of the Litz wire combination in the length direction, thereby fixing each knot 4 of the Litz wire combination.

[0029] In some specific embodiments, the multiple Litz wire bodies 3 are first uniformly twisted at a predetermined twisting density by a twisting machine, then a gap filling body 2 with viscosity and fluidity is coated on the surface of the Litz wire assembly, the gap filling body 2 covers all the inter-wire gaps, when the gap filling body 2 is not completely solidified, the encapsulation skin layer 1 is extruded to cover the surface layer of the gap filling body 2, and finally the gap filling body 2 and the encapsulation skin layer 1 are fused into a single encapsulation body by hot pressing. The single seamless encapsulation structure formed by extrusion and hot pressing is preferred, or a double-layer heat-shrinkable sleeve principle can be used, the innermost layer is the gap filling body 2 with a low melting point, and the outer layer is the encapsulation skin layer 1. When heated and shrunk, the gap filling body 2 in the inner layer melts and penetrates into the inter-wire gaps of the Litz wire assembly, and the encapsulation skin layer 1 in the outer layer shrinks and is shaped and combined with the gap filling body 2 into a single seamless encapsulation structure.

[0030] Specifically, the gap filling body 2 completely fills the gaps between the multiple Litz wire bodies 3 twisted with each other.

[0031] Specifically, the Litz wire assembly is located in the inner center of the encapsulation skin layer 1, and the length extension direction of the Litz wire assembly is consistent with the length extension direction of the encapsulation skin layer 1.

[0032] Specifically, the encapsulation skin layer 1 is a plastic body or a silica gel body.

[0033] Specifically, the two ends of the Litz wire assembly are flush with the two ends of the encapsulation skin layer 1, and the two ends of the encapsulation skin layer 1 are flush with the two ends of the gap filling body 2.

[0034] Specifically, the twisting direction of the Litz wire assembly is clockwise or counterclockwise.

[0035] Specifically, the Litz wire body 3 is a structure of an enameled wire.

[0036] Specifically, there are at least 2000 wire cores 5 in each Litz wire body 3.

[0037] In summary, the Litz wire assembly of this new Litz wire encapsulation structure is obtained by uniformly twisting according to a predetermined twisting density by a twisting machine, so that the problem of uneven twisting density caused by manual operation affecting the appearance can be avoided, and at the same time, the twisting machine can directly produce a Litz wire assembly with a precise length, thereby avoiding material waste, realizing standardized mass production, and greatly improving work efficiency. In addition, the seamless encapsulation structure formed by the encapsulation skin layer 1 and the gap filling body 2 tightly wraps the Litz wire body 3, so that each twist 4 of the multiple Litz wire bodies 3 is fixed, preventing the twist 4 from loosening and causing the multiple Litz wire bodies 3 to become parallel, ensuring that the electromagnetic shielding effect is durable and reliable. In addition, the encapsulated Litz wire body 3 can be directly used in the form of a finished product, which is convenient to operate and has strong practicality.
