Description

Technical Field

[0001] The utility model relates to the technical field related to drawn copper wires, in particular to a high-strength copper wire that prevents drawn wires from breaking. Background Art

[0002] Copper wire is usually used for conducting electricity. In order to enhance its performance, high-strength copper wire is needed for output. However, the existing high-strength copper wire that prevents wire drawing from breaking still has certain defects when used, such as;

[0003] For example, a high-strength, high-conductivity composite copper wire with a publication number of CN218420881U has a layer of oxygen-free copper concentrically coated on the surface of the copper alloy core wire. The composite copper wire is a composite copper wire in which the copper alloy core wire and the oxygen-free copper layer are electroplated. The oxygen-free copper layer of the composite copper wire accounts for 15-20% of the volume ratio of the copper alloy core wire. The high-strength, high-conductivity composite copper wire uses the oxygen-free copper layer, i.e., pure copper, which has excellent conductivity and signal transmission performance; at the same time, it has the mechanical properties of the copper alloy core wire, and the cost is low. It replaces the original pure copper wire, greatly reducing the manufacturing cost of the cable, and it is a high-strength, high-conductivity composite copper wire, and all indicators are higher than the relevant product standards.

[0004] However, this high-strength, high-conductivity composite copper wire still has the following disadvantages in actual use:

[0005] A layer of oxygen-free copper is concentrically coated on the surface of the copper alloy core wire for protection. In actual use, oxygen-free copper is usually more expensive due to its high purity and excellent performance. Therefore, the overall production will increase the manufacturing cost of the cable. In addition, the mechanical strength of oxygen-free copper is relatively low, so it may not provide sufficient mechanical protection. The whole is easily affected by the external environment, which reduces the overall service life. In addition, the overall structural stability is insufficient and it is prone to damage.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original high-strength copper wire that prevents wire drawing and breakage. Therefore, we proposed that the high-strength copper wire that prevents wire drawing and breakage can solve the above problems well. Utility Model Content

[0007] The utility model aims to provide a high-strength copper wire that is resistant to wire drawing and breakage, so as to solve the problem proposed in the above-mentioned background technology that a layer of oxygen-free copper is concentrically coated on the surface of a copper alloy core wire in the current market for protection. In actual use, the price of oxygen-free copper is usually high due to its high purity and excellent performance, so the overall production will increase the manufacturing cost of the cable, and the mechanical strength of oxygen-free copper is relatively low, so it may not provide sufficient mechanical protection, and the whole is easily affected by the external environment, which reduces the overall service life, and the overall structural stability is insufficient, which is easy to be damaged.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength copper wire that prevents wire drawing from breaking, comprising a copper core provided;

The rubber material of the rubber layer is an electrically insulating material, so the rubber layer can effectively isolate the electric field between the copper core and the external environment, preventing electrons and charges from escaping through the surface of the material, thereby improving the overall service life.

[0013] Preferably, a filling layer is installed on the inside of the protective layer, and the filling layer is made of polypropylene rope, which can effectively fill the gaps inside the protective layer. The filling layer is made of polypropylene rope, which has good flexibility and can effectively fill the gaps inside the protective layer, thereby improving the overall roundness and structural stability, facilitating the improvement of the overall strength, and reducing the breakage problem caused by low overall strength.

[0014] Preferably, an arc groove is provided at one end of the filling layer, and a reinforcing column is installed inside the arc groove. The arc groove provided on the filling layer facilitates the fitting and installation of the reinforcing column and the connection by glue, so that the whole interior is supported by the reinforcing column, reducing the problem of easy breakage after the whole is bent and improving the service life of the whole.

[0015] Preferably, an arc block is installed inside the filling layer, and the arc block is made of nylon material, which has good mechanical strength and stability.

[0016] Preferably, a mounting groove is provided inside the arc block, and the mounting groove is adapted to the internal structure of the copper wire.
