Description

Technical Field

[0001] The utility model relates to the technical field of industrial electric wires and cables, and particularly to a rope-type super-flexible cable conductor. Background Art

[0002] In order to improve the structural stability of the cable conductor in the prior art, copper and aluminum are usually used as the main materials to be processed into metal wires and stranded (as shown in the appendix). Figure 3 However, this also reduces the flexibility of the conductor. Due to the rigidity, there is a large force between the conductor metal wires. When the cable is bent and twisted, this force will also affect the service life of the cable.

[0003] As the requirements for the flexibility of the cable in the equipment manufacturing industry are getting higher, and the usage scenarios of flexible cables have higher requirements for flexibility, the stranding method in the prior art cannot meet the requirements.

[0004] Therefore, for the above reasons, the utility model designs a rope-type super-flexible cable conductor, which adopts the large-pitch bunching conductor process to improve the flexibility level of the cable, greatly reduces the force between the conductor single wires and the force between the insulation and the conductor, ensures the flexibility of the conductor, reduces the friction loss between the single wires inside the conductor, and extends the service life of the cable. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a rope-type super-flexible cable conductor, which adopts the large-pitch bunching conductor process to improve the flexibility level of the cable, greatly reduces the force between the conductor single wires and the force between the insulation and the conductor, ensures the flexibility of the conductor, reduces the friction loss between the single wires inside the conductor, and extends the service life of the cable.

[0006] To achieve the above purpose, the utility model provides a rope-type super-flexible cable conductor, which includes large-pitch bunching copper wires, annealed copper mesh belts, annealed copper wire braided layers, copper belts and invisible holes. The innermost layer of the cable conductor is large-pitch bunching copper wires, the outer layer of the large-pitch bunching copper wires is annealed copper mesh belts, the outer layer of the annealed copper mesh belts is annealed copper wire braided layers, and the annealed copper wire braided layers are composed of a number of regularly arranged invisible holes on the copper belts.

[0007] The annealed copper mesh belts are invisible hole annealed copper mesh belts.

[0008] The annealed copper wire braided layers are multi-layer rope annealed copper wire braided layers.

[0009] The copper wires in the large-pitch bunching copper wires are high-purity soft copper wires specially used for the electrical industry.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the present utility model, the conductor uses soft copper wire specifically for the electrical industry with high purity. The conductor has good electrical conductivity and tensile strength, is suitable for installation by users in small spaces, has good flexibility, and increases the service life of the product. The flexible copper wire undergoes nitrogen-filled annealing to obtain toughness exceeding that of common copper wires. During the nitrogen-filled annealing process, part of the cuprous oxide in the copper material is reduced, and at the same time, the surface strength of the copper wire is improved.

[0012] In the present utility model, the use of large-pitch bunching of copper wires reduces the force between single wires of the conductor and the force between the insulation and the conductor, ensuring the flexibility of the conductor. Among them, the flexible copper wire mesh wrapping is to wrap the bunched copper wires with a flexible copper wire mesh into a stable cable conductor, and the flexible copper wire mesh is a copper mesh belt with invisible holes. The present utility model also adopts a multi-layer rope-type annealed copper wire braid layer, making full use of the structural stability and flexibility of the rope-type braiding process.

[0013] The cable made by the present utility model is suitable for the power distribution systems of equipment such as robots, robotic arms, and mobile drag chains. It has good flexibility, integrated functions, is convenient for installation and maintenance, and has a low application cost. The laying and installation of this product are convenient. Through the intensive design of functions, the procurement cost of users is reduced, meeting the needs of modern intelligent production and life. Description of the Drawings

[0019] Now, the present utility model will be further described in conjunction with the drawings.

[0020] Refer to Figures 1-2 , the present utility model provides a rope-type super-flexible cable conductor, including large-pitch bunched copper wire 1, annealed copper mesh belt 2, annealed copper wire braid layer 3, copper strip 301, and invisible hole 5. The innermost layer of the cable conductor is large-pitch bunched copper wire 1, the outer layer of large-pitch bunched copper wire 1 is annealed copper mesh belt 2, the outer layer of annealed copper mesh belt 2 is annealed copper wire braid layer 3, and the annealed copper wire braid layer 3 is composed of a number of regularly arranged invisible holes 5 provided on copper strip 301.

[0021] The annealed copper mesh belt 2 is an invisible hole annealed copper mesh belt. The invisible holes 5 form tiny knife marks on the copper belt 301, thereby improving the flexibility of the copper belt.

[0022] The annealed copper wire braided layer 3 is a multi-layer rope annealed copper wire braided layer.

[0023] The copper wires in the large-pitch bundled copper wires 1 are high-purity soft copper wires specially used in the electrical industry.

[0024] Working principle:

[0025] The preparation process of the utility model is:

[0026] Copper wire preparation:

[0027] S1, copper wire drawing for electrical industry;

[0028] S2, copper wire nitrogen filling annealing;

[0029] Large pitch bunching:

[0030] S3, the annealed copper wire passes through the wire splitting die and the forming die;

[0031] S4, annealing copper wire tension adjustment;

[0032] S5, copper wires are drawn into bundles;

[0033] Invisible hole copper mesh tape wrapping:

[0034] S6, large pitch bundled copper wire wrapping and shaping;

[0035] S7, super flexible conductor packaged on a tray;

[0036] Annealed flexible copper wire multi-layer covered braided into a rope-type cable conductor:

[0037] S8, the semi-finished conductor wrapped with the invisible hole copper mesh tape passes through the tungsten steel mold for shaping;

[0038] S9, the conductor semi-finished product is made of annealed flexible copper wire to weave multiple layers of rope-type braiding.

[0039] The copper wire of the conductor in this utility model adopts the copper stranded conductor for electrical use that meets the IEC60228:2004 "Conductor of Insulated Cable" standard, which ensures the product's good conductivity, electromagnetic signal transmission performance and convenient installation operation. The conductor has good tensile strength, is suitable for installation by users in small spaces, has good flexibility, and increases the service life of the product;

[0040] The flexible copper wires in the large-pitch bundled copper wires 1 are subjected to nitrogen-charged annealing to obtain toughness exceeding that of common copper wires. During the nitrogen-charged annealing process, part of the cuprous oxide in the copper material is reduced, and at the same time, the strength of the copper wire surface is improved. The significance of nitrogen-charged annealing is to avoid the oxidation of the copper material caused by the contact of the copper wire with oxygen.

[0041] The large-pitch bundling of flexible copper wires reduces the force between the single conductor wires and the force between the insulation and the conductor, ensuring the flexibility of the conductor.

[0042] The key point of large-pitch bundling is to ensure that the tension of each single conductor wire is consistent, avoiding the arching of single wires and causing inconsistent internal forces in the conductor. In addition to adjusting the single-wire tension, the flexible copper wires must be evenly distributed when passing through the wire-dividing template to ensure the roundness of large-pitch bundling. The subsequent shaping die should be reasonably selected to avoid excessive stress on the bundled copper wires and causing extrusion deformation.

[0043] The flexible copper mesh wrapping is to wrap the bundled copper wires with a flexible copper mesh to form a stable cable conductor. The flexible copper mesh is a copper mesh belt with invisible holes. The copper mesh belt with invisible holes is formed by rolling a copper strip on a super-flat processing roller shaft with a precision roller-type tool, making the copper strip form tiny knife marks, thereby improving the flexibility of the copper strip. When the flexible copper mesh is deformed under force, it will not generate a large force on the internal copper wires, thus ensuring the flexibility and shape stability of the conductor.

[0044] According to the rope braiding process, annealed flexible copper wires are used to braid multiple layers of copper wire braiding layers on the surface of the conductor semi-finished product wrapped with a flexible invisible copper mesh. The structural stability and flexibility of the rope-type braiding process are fully utilized to ensure the flexibility of the conductor while ensuring the structural stability of the conductor, so that the product will not break during the continuous movement and bending of the equipment. According to needs, the number of braiding layers can be one layer or multiple layers.

[0045] The technical parameters of the present utility model are as follows:

[0046] The bending radius is:

[0047] Under moving working conditions: the minimum cable outer diameter × 3;

[0048] Under fixed working conditions: the minimum cable outer diameter × 1;

[0049] The torsion range: max. ±360° / m;

[0050] The effective bending times: 500,000 times;

[0051] The present utility model has a long service life, is safe and reliable in use, is convenient to install, has good mechanical properties such as wear resistance, impact resistance, and tear resistance, and has good bending resistance, and can still normally conduct current after 500,000 times of moving bending.

[0052] The above is only the preferred embodiment of the present utility model, which is only used to help understand the method and its core idea of the present application. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.

[0053] As a whole, the present utility model solves the problem in the prior art that the cable made of stranded metal wires has excessive stiffness and insufficient flexibility, thus affecting the service life and application scenarios. By adopting a large pitch bunching process, a super flexible cable conductor is designed, which minimizes the force between the single wires of the conductor and the force between the insulation and the conductor, ensures the flexibility of the conductor, reduces the frictional loss between the single wires inside the conductor, and extends the service life of the cable.
