Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically an improved cable winding structure for producing cable products. Background Technology

[0002] In cable production, the winding process is a crucial step in ensuring stable cable performance and improving production efficiency. Traditional winding methods typically use a single material, which to some extent limits the cable's performance and application range.

[0003] The existing technology lacks a new winding method to adapt to the winding requirements of different applications and improve cable performance. Utility Model Content

[0004] To address the problems existing in the background art, this utility model provides an improved cable winding structure, which enhances the cable's structural stability, cable service life, and shielding stability.

[0005] The purpose of this invention is to provide an improved cable winding structure, which is produced using a braiding machine. One or more spindles of fiber filaments are fixed in the reverse spindle of the winding wire to achieve winding for different applications, thereby improving the performance and applicability of the cable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The technical solution adopted in this utility model is:

[0008] Including the cable body;

[0009] This includes a main winding wire wrapped around the outside of the cable body to form a shielding layer;

[0010] It includes a layer of metal foil wrapped around the main winding wire as an inner layer;

[0011] This includes one or two filaments of fiber wound in a reverse-spindle manner around the metal foil as an outer layer.

[0012] This forms a winding structure of "metal foil + single-layer fixed winding" or "metal foil + double-layer fixed winding" to fix the cable winding shielding structure and further improve the cable's shielding performance and structural stability.

[0013] The winding rotation direction of one or two spindles of fiber is opposite to that of the main winding filament.

[0014] The single or double fiber filaments are used for mounting the reverse spindle of the winding yarn on the braiding machine.

[0015] The metal foil is one of copper foil, aluminum foil, or metal strip.

[0016] The fiber filaments are made of either nylon or bulletproof yarn.

[0017] The main winding wire is one of the following: copper wire, tin-plated copper wire, alloy wire, and copper foil wire.

[0018] The beneficial effects of this utility model are:

[0019] This invention utilizes four spindles of fiber filaments mounted on a braiding machine to achieve winding of different materials, thereby improving the performance and applicability of the cable. Furthermore, by selecting different winding methods, the specific needs of various cable products can be met.

[0020] The innovation of this utility model is reflected in the following aspects:

[0021] Material combination innovation: Breaking through the limitations of traditional single-material winding, one or more spindles of fiber filaments 4 (such as nylon filaments, bulletproof filaments, etc.) are installed in the reverse spindle of the winding wire, and used in combination with metal winding wires (copper wire, tinned copper wire, alloy wire, copper foil wire, etc.). The fiber filaments 4 play a fixing role, and when combined with different types of metal winding wires, different performance improvements are achieved, broadening the performance range and application scenarios of cables.

[0022] Innovative winding methods: Multiple winding methods are available, including 3-layer metal foil + single-layer fixed winding and 3-layer metal foil + double-layer fixed winding. Different winding methods can meet the specific needs of different cable products. For example, double-layer fixed winding further enhances structural stability compared to single-layer fixed winding; 3-layer metal foil + single or double-layer fixed winding improves cable shielding performance on the original basis. The 3-layer metal foil can be made of copper foil, aluminum foil, metal tape, etc., enriching the selection of winding materials and enhancing product adaptability.

[0023] Overall performance improvement innovation: By installing four spindles of fiber filaments on the braiding machine to achieve winding of different materials, combined with diversified winding methods, the performance and applicability of the cable are ultimately improved, solving the problem that traditional winding methods limit the performance and application range of cables, and meeting the needs of cables in more different scenarios.

[0026] Figure 2This is a structural schematic diagram of Embodiment 2 of the present invention.

[0027] In the diagram: 1. Cable body; 2. Main winding wire; 3. Metal foil; 4. Fiber filament. Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The implementation of this utility model is as follows:

[0030] Example 1:

[0031] Includes cable body 1;

[0032] This includes a layer of tinned copper wire wound around the outside of the cable body 1 to form a shielding layer;

[0033] This includes an inner layer of aluminum foil wrapped around a tin-plated copper wire;

[0034] This includes a nylon filament wound in a reverse-rotation manner around an aluminum foil as an outer layer, with the winding rotation direction of the nylon filament being opposite to that of the main winding filament 2.

[0035] This forms a "metal foil 3 + single-layer fixed winding" winding structure to fix the cable winding shielding structure.

[0036] In specific implementation, the improved cable winding structure is prepared in the following manner, including the following steps:

[0037] a) Prepare the braiding machine and install one or more spindles of fiber filament 4 as a fixation in the reverse spindle of the winding yarn;

[0038] b) Select the appropriate winding wire according to the type of material to be wound. The winding wire includes copper wire, tin-plated copper wire, alloy wire, and copper foil wire.

[0039] c) Select one of the following winding methods according to the cable's usage requirements:

[0040] 1. Metal foil 3+ single-layer fixed winding;

[0041] After the cable is wound with the main winding wire 2 and covered with metal foil 3, a spindle of fiber filament 4 is installed in the reverse spindle of the winding wire to fix the cable winding shielding structure and improve the cable shielding performance.

[0042] 2. Metal foil 3+ double-layer fixed winding;

[0043] After the cable is wound with the main winding wire 2 and covered with metal foil 3, two spindles of fiber filament 4 are installed in the reverse spindle of the cable winding wire to further improve the shielding performance and structural stability of the cable.

[0044] d) The winding yarn is wound by a braiding machine to form a winding shield.

[0045] This embodiment underwent three tests totaling four months. The test results were as follows: after the first torsion test of 500,000 cycles, the winding structure was found to be unchanged after dissecting the cable; after the second bending test of 500,000 cycles, the winding structure was found to be unchanged after dissecting the cable; and after the third cable chain test of 500,000 cycles, the winding structure was found to be unchanged after dissecting the cable.

[0046] Example 2:

[0047] Includes cable body 1;

[0048] This includes a layer of copper foil wire wrapped around the outside of the cable body 1 to form a shielding layer;

[0049] It includes a layer of metal cloth wrapped inside the copper foil wire as an inner layer;

[0050] This includes two spindles of bulletproof wire wound in a reverse-rotation manner around the metal strip, serving as the outer layer. The winding rotation direction of the two spindles of bulletproof wire is opposite to that of the main winding wire 2.

[0051] This forms a "metal tape 3+ double-layer fixed winding" winding structure, which improves the shielding performance and structural stability of the cable.

[0052] The preparation process in this embodiment is the same as in embodiment 1. After three tests totaling four months, the test results were as follows: after the first torsion test of 1 million times, the winding structure was found to be unchanged after dissecting the cable; after the second bending test of 1 million times, the winding structure was found to be unchanged after dissecting the cable; and after the third cable chain test of 1 million times, the winding structure was found to be unchanged after dissecting the cable.

[0053] Comparative example: Conventional non-fixed winding

[0054] Includes cable body 1;

[0055] This includes a layer of tinned copper wire wrapped around the outside of the cable body 1, which serves as a shielding layer.

[0056] This comparative example underwent three tests. The test results were as follows: after the first torsion test of 500,000 cycles, the cable was dissected and the winding wire position was found to be disordered and the structure changed. After the second bending test of 500,000 cycles, the cable was dissected and the winding wire position was found to be disordered and the structure changed. After the third cable chain test of 500,000 cycles, the cable was dissected and the winding wire position was found to be disordered and the structure changed.
