While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein.

Description of the preferred embodiments section
Example 1:
referring to fig. 1 to 4, the present embodiment provides a wire core suitable for a high-speed high-frequency cable, including a conductor 11 and an insulating medium layer 12 wrapped on the conductor 11. The insulating medium layer 12 is internally and uniformly provided with a plurality of holes 121 parallel to the axis of the conductor 11 around the conductor 11, and a supporting structure 122 is formed between adjacent holes 121.
In any cross section of the wire core, the cross sections of the holes 121 are identical in shape and are in axisymmetric patterns, and the symmetry axis L of the cross section of each hole 121 intersects with the circle center O of the cross section of the conductor 11.
A plurality of holes 121 parallel to the axis of the conductor 11 are uniformly formed around the conductor 11 in the insulating dielectric layer 12, and supporting structures 122 are formed between the adjacent holes 121, and the supporting structures 122 are uniformly distributed around the conductor 11, so that the structural stability of the insulating dielectric layer 12 can be maintained when the wire core is stressed, and the dielectric constant of the insulating dielectric layer 12 can be maintained stable. The cross-sectional shapes of the holes 121 are the same, and the symmetry axes L intersect with the center O (or axis) of the cross-section of the conductor 11, so that the symmetry axis L of each hole 121 is also the symmetry axis of the wire core, so that the holes 121 are uniformly distributed around the whole conductor 11, and the dielectric constants in all directions are ensured to be consistent. On the other hand, the combination of the holes 121 and the supporting structure 122 not only increases the toughness of the insulating dielectric layer 12 so that it is not easily broken when being stretched, bent or even pressed, but also reduces the weight of the core and the dielectric constant. And moreover, the symmetrical structure of the wire core ensures the accuracy of the die, is favorable for improving the processing accuracy, and is more suitable for high-frequency and high-speed transmission cables with fine structures.
In practical application, the cross section of the hole 121 may be in a symmetrical pattern such as a circle, an ellipse, or an equilateral polygon, and the symmetry axis L thereof intersects with the center O of the conductor 11, so that each hole 11 is distributed around the whole core in a symmetrical circumference, and the dielectric constants in all directions are ensured to be consistent.
In some possible solutions, referring to fig. 1, in any cross section of the wire core, the cross section of each hole 121 is isosceles triangle, and each isosceles triangle is an inverse triangle, and the cross section of the support structure 122 is columnar.
In this embodiment, the reverse triangle means an isosceles triangle whose apex angle is directed to the axis of the conductor 11, and the forward triangle means an isosceles triangle whose apex angle is directed opposite to the apex angle of the reverse triangle.
In practical applications, please continue to refer to fig. 1, the cross section of the conductor 11 is a circular cross section, and the vertical line from the top to the bottom of each reverse triangle (i.e. the symmetry axis L) intersects with the center O of the circular cross section of the conductor 11; the center points S1 are uniformly distributed on the circumference of the concentric circles of the circular cross section of the conductor 11, i.e., the distances from the center point S1 to the center point O of each reverse triangle are equal.
In practice, the support structure 122 has a cylindrical cross-sectional shape, and the width of one end thereof away from the conductor 11 is smaller than the width of the other end thereof.
In practical applications, the isosceles triangles may be equilateral triangles; or the waist triangles may have only two sides equal and the angle of the apex angle is greater than the angle of the base angle, for example, the apex angle may be set at 70, where the base angle is 55. The angle of the top angle is designed to be larger than the angle of the bottom angle, so that the support structure is favorable for forming a columnar structure with a small outer end and a large inner end, the support effect is better, the cross section of the hole 11 is prevented from being too narrow, and the machining precision of the wire core is further improved.
Because the triangle structure stability is strongest, therefore, when the cross section of hole 121 is isosceles triangle, when the sinle silk receives external force such as extrusion bending, can have higher compressive strength to triangle-shaped is more easy to rebound after external force disappears. The symmetry axis of each isosceles triangle is also the symmetry axis of the wire core, and the whole wire core is of a symmetrical circumference structure, so that the dielectric constants in all directions can be guaranteed to be consistent, the dielectric constant can be reduced to 1.1 from original 2.3, after the dielectric constant is reduced, the transmission rate is faster, and the rate can be increased from 32G to 64G. In addition, the vertex angle of the reverse triangle is arranged to point to the hole of the circle center of the lead, so that the stress of the position of the vertex angle is more concentrated when the wire core is bent, the adhesive force of the insulating medium layer attached to the conductor is further improved, and the protection effect obtained when the wire core is subjected to external force is better.
In some possible solutions, referring to fig. 2, each isosceles triangle is a regular triangle, the distance from the center point S2 of each regular triangle to the center O is equal, and the cross-sectional shape of the support structure 122 is columnar.
In practical application, as shown in fig. 2, the vertical line from the vertex to the base of each forward triangle (i.e., the symmetry axis L) intersects with the center O of the circular cross section of the conductor 11; the center points S2 are uniformly distributed on the circumference of the concentric circles of the circular cross section of the conductor 11, i.e., the distances from the center point S2 of each of the forward triangles to the center O are equal.
In practical applications, when the cross section of each hole 11 is in the shape of a regular triangle or a reverse triangle, the number of holes 121 provided around the conductor 11 may be an odd number, such as 9, 11 or 13; an even number, such as 8, 10 or 12, is also possible. When the number of the holes 121 is an even number, the holes 121 may be uniformly and symmetrically distributed around the conductor 11.
In some possible implementations, referring to fig. 3, the isosceles triangle includes a forward triangle and a reverse triangle, and the forward triangle and the reverse triangle are spaced apart.
With continued reference to fig. 3, the distances from the center point S1 of each reverse triangle to the center point O are equal, the distances from the center point S2 of each forward triangle to the center point O are also equal, and the distances from the center point S1 of each reverse triangle to the center point O are greater than the distances from the center point S2 of each forward triangle to the center point, so that the vertex angle of each reverse triangle is flush or substantially flush with the edge of each forward triangle, interference between each forward triangle and the adjacent reverse triangle is avoided, and breakage of the wire core caused by too thin position of the support structure 122 close to the conductor 11 is avoided.
In practical applications, as shown in fig. 3, the number of the forward triangles and the reverse triangles is equal, and may be an even number, for example, 6 for each of the forward triangles and the reverse triangles, and total 12 holes. The two support structures 122 on both sides of each regular triangle are in a group, uniformly and symmetrically distributed around the conductor 11, and the sides L1 and L2 of the two support structures 122 are parallel to each other. Therefore, the whole wire core is in a symmetrical circumferential structure, the dielectric constants in all directions are ensured to be consistent, and the flexibility of the wire core is improved.
In some possible embodiments, referring to fig. 4, the core further includes an outer coating 13 that is wrapped around the insulating dielectric layer 12.
In some possible implementations, the material of the conductor 11 includes zinc-plated copper or tin-plated copper. The insulating medium layer 12 can be made by foaming process, and the material of the insulating medium layer comprises polypropylene PP, perfluoroethylene propylene copolymer FEP, polyethylene PE, soluble polytetrafluoroethylene PFA or polytetrafluoroethylene PTFE. The material of the outer coating layer comprises polyvinyl chloride PVC, thermoplastic rubber TPE, polyurethane PU, ethylene-tetrafluoroethylene copolymer ETFE, soluble polytetrafluoroethylene PFA, polypropylene PP, polyethylene PE, crosslinked polyethylene XLEP or chlorinated polyethylene CPE and the like.
In some possible solutions, the core is applied in a high-frequency high-speed cable of fine structure, the conductor 11 having a diameter of 0.16 to 0.2mm; the diameter of the insulating medium layer 12 is 0.32-0.4mm; the isosceles triangle of the cross section of the hole has a side length of 0.02mm.
In practical application, the wire diameter and the impedance of the wire core 10 can be selected according to practical situations.
