Abstract
Description
Technical Field
[0001] This utility model relates to the field of profiled conductor technology, specifically a profiled conductor structure that is easy to manufacture. Background Technology
[0002] Conductors are typically made of stranded round single wires. To reduce the conductor's outer diameter and improve its stability, roundness, and smoothness, a compaction stranding method is used. However, the compaction process deforms the single wire, reducing its strength and causing work hardening, which increases the resistivity of the single wire and consequently, the conductor's resistance. The solution is to use a profiled stranded conductor structure instead of the compacted round wire stranding structure. Profiled wires can be drawn into the designed shape during the drawing process and do not require compaction during stranding, thus avoiding the work hardening problem that increases resistance. Furthermore, profiled stranded conductors have a higher overall fill factor than compacted round wire conductors; for the same nominal cross-section, profiled stranded conductors have a smaller outer diameter and lower cost. However, compared to round single wires, profiled wires are more prone to directional deviation during stranding, which can lead to substandard conductor resistance or uneven surface finish, causing quality problems such as partial discharge. Therefore, production efficiency is lower compared to round single wire stranded conductors. Utility Model Content
[0003] The purpose of this invention is to provide a profiled conductor structure that is easy to manufacture, thereby overcoming the shortcomings of the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a profiled conductor structure that is easy to manufacture, comprising:
[0005] The wire core has an elliptical cross-sectional shape and each wire core has a major axis A and a minor axis B.
[0006] A shaped wire assembly is disposed outside the wire core. The shaped wire assembly is composed of several first shaped wires and second shaped wires spliced together. A groove is provided on one side of the waistline of the first shaped wire and the second shaped wire, and a protrusion is provided on the other side of the waistline of the first shaped wire and the second shaped wire.
[0007] The first type of wire is located at the short axis B of the wire core, and the second type of wire is located at the long axis A of the wire core.
[0008] Preferably, the included angle between the waistlines on both sides of the first profile 2 and the second profile 3 is set to 45 degrees.
[0009] Preferably, the bottom edge of the first profile is provided with a first adapting surface, which is adapted to the outer surface corresponding to the short axis B of the wire core.
[0010] Preferably, the bottom edge of the second profile is provided with a second fitting surface, which is fitted to the outer surface corresponding to the long axis A of the wire core.
[0011] Preferably, the cross-sectional shape of the profile component is set to a hollow ellipse.
[0012] Preferably, the outer surface of the profile assembly is provided with an insulating protective layer.
[0013] In the above technical solution, the present invention provides a shaped conductor structure that is easy to produce. The shaped wire in the stranded conductor is trapezoidal. To solve the problem that the direction of the single wire is easily deflected during the stranding process of the frame stranding machine, which reduces the production speed, corresponding grooves and protrusions are set at the waist line positions on both sides to ensure that adjacent shaped wires are connected to each other. After the wire is drawn, the shaped wire is not easily deformed. When stranding, the shaped wires are more firmly joined together and will not deflect or shift. The structure is stable, the conductor surface is smoother and rounder, and the gap between the surfaces of each layer is smaller. Therefore, the production efficiency of the shaped conductor is greatly improved, and the probability of conductor defects is reduced. Moreover, the shaped wire and the wire core are not easily deflected, and the structure is stable after stranding. Attached Figure Description

[0020] Please see Figure 1-3 The present invention provides a readily manufactured profiled conductor structure, comprising:
[0021] The wire core 1 has an elliptical cross-sectional shape and each wire core 1 has a major axis A and a minor axis B.
[0022] A shaped wire assembly is disposed outside the wire core 1. The shaped wire assembly is composed of several first shaped wires 2 and second shaped wires 3 spliced together. A groove 5 is provided on one side of the waistline of the first shaped wires 2 and second shaped wires 3, and a protrusion 6 is provided on the other side of the waistline of the first shaped wires 2 and second shaped wires 3.
[0023] The first type of wire 2 is located at the short axis B of the wire core 1, and the second type of wire 3 is located at the long axis A of the wire core 1.
[0024] The cross-sectional shape of the first type 2 and the second type 3 is set as a trapezoidal structure. This avoids the problem of the single wire direction easily deflecting and reducing the production speed during the stranding process of the frame stranding machine. By setting corresponding grooves 5 and protrusions 6 on the waist lines on both sides of the first type 2 and the second type 3, the adjacent first type 2 and the second type 3 are connected to each other during the stranding process. This structure is not easy to deform after drawing, and the strands are more stable during stranding. The first type 2 and the second type 3 will not deflect or shift, the structure is stable, the conductor surface is smoother and rounder, and the gap between the surfaces of each layer is smaller. Therefore, the production efficiency of the conductor is greatly improved and the probability of defects is reduced. In addition, the first type 2 and the second type 3 are elliptically attached to the wire core 1, so the first type 2 and the second type 3 are not easy to deflect to the wire core 1, and the structure is stable after stranding.
[0025] The included angle between the waistlines on both sides of the first profile 2 and the second profile 3 is set to 45 degrees.
[0026] The first type of wire 2 and the second type of wire 3 can be evenly distributed outside the core 1, and the first type of wire 2 and the second type of wire 3 can be mass-produced.
[0027] The bottom edge of the first type of wire 2 is provided with a first fitting surface 8, which is fitted to the outer surface corresponding to the short axis B of the wire core 1. The first type of wire 2 and the wire core 1 have a specific fitting surface to ensure accurate fitting between the first type of wire 2 and the wire core 1.
[0028] The bottom edge of the second type of wire 3 is provided with a second fitting surface 7, which is fitted to the outer surface corresponding to the long axis A of the wire core.
[0029] The second type of wire 3 and the wire core 1 have a specific mating surface to ensure accurate mating between the second type of wire 3 and the wire core 1.
[0030] The cross-sectional shape of the profile assembly is set to a hollow ellipse. The elliptical design ensures that the profile assembly and the core 1 are not easily deflected.
[0031] The profile assembly is provided with an insulating protective layer on its exterior. The insulating protective layer serves to isolate the interior from the exterior, thus providing insulation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
