Description

Technical Field

[0001] This utility model relates to the field of alloy stranded wire technology, specifically to a corrosion-resistant silver-plated copper alloy stranded wire. Background Technology

[0002] Stranded wire is a wire made of multiple metal wires twisted together according to certain rules. By changing the number, diameter, twisting direction and pitch of the single wires, composite wires with specific mechanical properties, electrical conductivity or structural strength are formed. It is widely used in the power industry and other fields. Its core advantage is that by dispersing stress and optimizing the structure, it overcomes the defects of single wires such as easy breakage and poor flexibility. However, some problems still occur in the actual use of existing alloy stranded wires.

[0003] Based on this, a search on the patent website revealed that Chinese patent application number CN202221704410.0 discloses a medium-strength aluminum alloy stranded wire;

[0004] It is evident that the aforementioned patent applications have shortcomings: when existing alloy stranded wires are used, most alloy stranded wires have a relatively simple structure, which can easily cause damage when used in corrosive environments. Furthermore, the overall compressive strength of alloy stranded wires is poor, which greatly affects their normal use.

[0005] To address the aforementioned problems, a corrosion-resistant silver-plated copper alloy stranded wire is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a corrosion-resistant silver-plated copper alloy stranded wire. By using this device, the problems of existing alloy stranded wires, which are mostly simple in structure and easily damaged when used in corrosive environments, as well as having poor overall compressive strength, are solved.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant silver-plated copper alloy stranded wire, comprising an alloy stranded wire body and an inner stranded wire fixedly connected inside the alloy stranded wire body. The alloy stranded wire body has a corrosion-resistant structure inside, which protects the alloy stranded wire body. The corrosion-resistant structure includes a support frame fixedly connected inside the alloy stranded wire body, and an outer stranded wire is also fixedly connected inside the alloy stranded wire body.

[0008] Preferably, the inner stranded wire is fixedly connected to an inner corrosion-resistant layer, and three sets of the inner corrosion-resistant layer are provided, with conductive wires fixedly connected inside the inner corrosion-resistant layer.

[0009] The above-mentioned structural design features an inner corrosion-resistant layer that wraps around the conductive wires to form triple independent protection. This not only enhances the corrosion resistance of the conductive wires through the use of silver-copper alloy material, but also disperses the current load using multiple sets of designs, reducing the loss of a single set of conductive wires, while ensuring the stability of conductivity.

[0010] Preferably, the inner stranded wire is further fixedly connected to a pressure-resistant layer, which is fixedly connected to the outside of the inner corrosion-resistant layer.

[0011] With the above-mentioned structural design, the pressure-resistant layer is attached to the inner corrosion-resistant layer, which can directly withstand the external radial pressure and avoid the inner corrosion-resistant layer and conductive wire from breaking due to extrusion deformation. At the same time, its elastic material can buffer the impact and is suitable for high-pressure or vibration environments.

[0012] Preferably, a pressure-resistant ring is fixedly connected to the outer side of the support frame, and the pressure-resistant ring is in contact with the inner wall of the alloy stranded wire body.

[0013] With the above-mentioned structural design, the pressure-resistant ring is tightly fitted to the inner wall of the alloy stranded wire body to form a ring support structure, which evenly distributes the external pressure to the support frame, avoids excessive local stress that could cause the stranded wire to deform, and enhances the rigidity of the overall structure, making it suitable for high-tension installation scenarios.

[0014] Preferably, the support frame has an outer corrosion-resistant layer inside, the support frame is cross-shaped, and multiple sets of external twisted wires are provided.

[0015] With the above-mentioned structural design, the cross-shaped support frame divides the interior of the alloy stranded wire body into four independent areas, which not only provides stable support for the outer stranded wires, but also prevents external corrosive media from penetrating the central area through the internal and external corrosion-resistant layers; multiple sets of outer stranded wires are distributed in the cross gaps to improve the overall conductivity redundancy.

[0016] Preferably, the outer stranded wire is disposed on the outside of the support frame, and the outer stranded wire is in contact with the support frame and the inner wall of the alloy stranded wire body.

[0017] With the above-mentioned structural design, the tight contact between the outer stranded wire and the support frame and the inner wall of the main body not only prevents the wire from shaking and wearing due to the rigidity of the support frame, but also forms a dual-circuit design of "inner stranded wire + outer stranded wire". When the inner stranded wire fails, the circuit can be quickly switched to the outer stranded wire to ensure the continuity of the circuit.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This application proposes a corrosion-resistant silver-plated copper alloy stranded wire, which solves the problems of existing alloy stranded wires, which are mostly simple in structure and easily damaged in corrosive environments. Furthermore, the overall compressive strength of alloy stranded wires is poor, greatly affecting their normal use. In this application, the alloy stranded wire body can be installed in a designated position. When exposed to corrosive fluids, the outer corrosion-resistant layer on the support frame and the inner corrosion-resistant layer inside the inner stranded wire protect both the inner stranded wire and the alloy stranded wire body. The inner corrosion-resistant layer is composed of a silver-copper alloy, providing highly efficient corrosion resistance, while the outer corrosion-resistant layer is composed of a nickel-based alloy, effectively preventing damage to the alloy stranded wire body during use. The support frame and compressive strength layers significantly improve the compressive strength of the alloy stranded wire body, enabling its use in high-pressure environments. This enhances the corrosion resistance of the alloy stranded wire body and improves the overall performance of the device.

[0020] 2. This application proposes a corrosion-resistant silver-plated copper alloy stranded wire, which solves the problem that existing alloy stranded wires often transmit power through a single cable, and cannot provide emergency power transmission when the cable is damaged. During use, the inner stranded wires inside the alloy stranded wire body can maintain circuit continuity, and when the inner stranded wires are damaged, the outer stranded wires inside the alloy stranded wire body can disconnect the circuit. This allows the alloy stranded wire body to still function even when the inner stranded wires are damaged, thus improving the overall performance of the alloy stranded wire body.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example 1:

[0032] To address the problems of existing alloy stranded wires, which are often structurally simple and prone to damage in corrosive environments, and whose overall compressive strength is poor, significantly affecting their normal use, this embodiment discloses the following technical solution, specifically as follows: Figures 1-5As shown, an inner corrosion-resistant layer 111 is fixedly connected inside the inner stranded wire 11, and three sets of the inner corrosion-resistant layer 111 are provided. A conductive wire 112 is fixedly connected inside the inner corrosion-resistant layer 111. A pressure-resistant layer 113 is also fixedly connected inside the inner stranded wire 11, and the pressure-resistant layer 113 is fixedly connected to the outside of the inner corrosion-resistant layer 111. A pressure-resistant ring 121 is fixedly connected to the outside of the support frame 12. The pressure-resistant ring 121 is in contact with the inner wall of the alloy stranded wire body 1. An outer corrosion-resistant layer 122 is provided inside the support frame 12. The support frame 12 is cross-shaped. When in use, the alloy stranded wire body 1 can be installed in a designated position first. When affected by external corrosive fluids, the support... The outer corrosion-resistant layer 122 on the frame 12 and the inner corrosion-resistant layer 111 inside the inner stranded wire 11 can protect the inner stranded wire 11 and the alloy stranded wire body 1. The inner corrosion-resistant layer 111 is composed of silver-copper alloy, which can achieve a highly efficient corrosion resistance effect. At the same time, the outer corrosion-resistant layer 122 is composed of nickel-based alloy, which can effectively prevent damage to the alloy stranded wire body 1 during use. In addition, the setting of the support frame 12 and the pressure-resistant layer 113 greatly improves the pressure resistance of the alloy stranded wire body 1, enabling it to be used in high-pressure environments. This achieves the effect of improving the corrosion resistance of the alloy stranded wire body 1 and improving the performance of the device.

[0033] Example 2:

[0034] To address the issue that existing alloy stranded wires, which typically transmit power via a single cable and cannot provide emergency power when the cable is damaged, disclose the following technical solution: Figure 3 As shown, multiple sets of external twisted wires 13 are provided. The external twisted wires 13 are located on the outside of the support frame 12 and are in contact with the support frame 12 and the inner wall of the alloy stranded wire body 1. During use, the circuit can be connected through the internal twisted wires 11 inside the alloy stranded wire body 1. When the internal twisted wires 11 are damaged, the circuit can be switched on or off through the external twisted wires 13 inside the alloy stranded wire body 1. This enables the alloy stranded wire body 1 to still be used even when the internal twisted wires 11 are damaged, thus improving the performance of the alloy stranded wire body 1.
