Description

Technical Field

[0001] This invention relates to the field of conductor technology, specifically to an aluminum-nickel welded sheet. Background Technology

[0002] Existing aluminum rigid connectors generally employ electroplating for surface treatment. This process is complex, involving multiple pretreatment, coating deposition, and post-treatment steps. Each step requires precise control of parameters such as temperature, concentration, and time. Deviations in any step can directly lead to uneven coating, insufficient adhesion, or surface defects, significantly reducing the product's pass rate and increasing scrap rates. This increases raw material and energy consumption, ultimately raising overall manufacturing costs and weakening the company's market competitiveness. Furthermore, electroplating relies on plating solutions containing heavy metal ions and harmful chemicals. The production process inevitably generates large amounts of toxic wastewater and harmful gases. These pollutants, once discharged, directly pollute water bodies and the atmosphere, disrupting the ecological balance and threatening human health. They also lead to a chain reaction of soil acidification and biodiversity loss. This environmental pollution not only violates the core principle of green manufacturing, which is to achieve efficient production by reducing resource consumption and waste emissions, but also contradicts the concept of sustainable development. It exacerbates resource waste and ecological degradation, forcing the industry to face increasingly stringent environmental regulations. This limits the expansion potential of aluminum rigid connectors in modern industrial applications and hinders the entire manufacturing industry's transformation towards an environmentally friendly model. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an aluminum-welded nickel sheet, which solves the problems of complex electroplating processes, low yield rates, and high production costs associated with existing aluminum rigid connectors. At the same time, the resulting heavy metal pollution seriously threatens the ecological environment and violates the concepts of green manufacturing and sustainable development.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: An aluminum-welded nickel sheet includes: an aluminum busbar with an insulating layer on its outer surface; a central bending zone in the middle of the aluminum busbar, the central bending zone being integrally bent from the aluminum busbar; aluminum ports at both ends of the aluminum busbar, the aluminum ports being formed by bending outwards from the ends of the aluminum busbar and connecting to the aluminum busbar at a right angle; a connecting side groove being provided at the connection between the aluminum busbar and the aluminum ports; and pure nickel strips being attached to the outer surfaces of both aluminum ports, the pure nickel strips being fixedly connected to the aluminum ports by hot-press welding.

[0005] Preferably, the pure nickel strip is disposed on the outer surface of the aluminum port.

[0006] Preferably, the connecting side slot is configured as an arc-shaped slot structure, and the connecting side slot is configured to extend through the thickness direction of the aluminum busbar.

[0007] Preferably, the central bending area is configured as a circular arc transition structure, and the central bending area is located at the middle position along the length of the aluminum busbar.

[0008] Preferably, the insulating layer is disposed on the outer surface of the aluminum busbar, and the insulating layer forms an opening structure at the two aluminum ports.

[0009] Preferably, the two aluminum ports are respectively located at both ends of the aluminum busbar, and the two aluminum ports are arranged in a centrally symmetrical manner with respect to the aluminum busbar.

[0010] Preferably, the side of the pure nickel strip closest to the insulating layer is located inside the insulating layer, and both the pure nickel strip and the aluminum port are provided with connection holes.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides an aluminum-welded nickel sheet, which has the following beneficial effects: 1. This aluminum-welded nickel sheet utilizes pure nickel strips to directly cover the outer surface of the aluminum end through hot-press welding, replacing the traditional electroplating process. This avoids complex processes such as multiple chemical pretreatments, plating solution deposition, and post-treatment, thereby significantly improving the product processing qualification rate and production stability. At the same time, it completely eliminates the emission of heavy metal wastewater, harmful gases, and chemical pollutants generated during the electroplating process, achieving clean production from the source. This meets the requirements of green manufacturing and sustainable development, effectively reduces the environmental pollution burden, and circumvents increasingly stringent environmental regulations.

[0012] 2. This aluminum-welded nickel sheet utilizes the central arc transition bending area formed by the integral bending of the aluminum strip, giving the conductor a three-dimensional spatial shape and good elastic buffering characteristics. When subjected to external impact or vibration, it can effectively absorb and disperse stress, significantly reducing the risk of excessive bending, fatigue fracture or permanent structural deformation of the aluminum material, thereby improving the overall mechanical reliability and service life of the connector.

[0013] 3. This aluminum-welded nickel sheet utilizes a structure in which the aluminum end is bent outward at a right angle and a through-type arc-shaped connection side slot is set in the transition area. This structure not only allows for flexible changes in the connection direction to adapt to various installation layouts, but also effectively reduces stress concentration at the bend through local thinning and stress release design, preventing cracks, warping or fatigue failure in the connection area, and ensuring the structural integrity and electrical contact stability for long-term use.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-5An aluminum-welded nickel sheet includes: an aluminum busbar 1, with an insulating layer 2 disposed on the outer surface of the aluminum busbar 1. The aluminum busbar 1 serves as the main conductive component of the entire structure, used to carry current transmission and as the base for the installation of other structures. The insulating layer 2 covers the outer surface of the aluminum busbar 1, providing electrical isolation between the aluminum busbar 1 and the external structure during installation and use. This reduces interference from external conductive structures and prevents accidental contact with conductive components. A central bending area 3 is provided in the middle of the aluminum busbar 1. The central bending area 3 is formed by bending the aluminum busbar 1 integrally. By forming a bending structure in the middle of the aluminum busbar 1, a three-dimensional spatial shape is created at this location. Compared to a straight structure, this increases the overall structural toughness and provides elastic buffering when subjected to external forces, reducing the likelihood of bending deformation or structural damage to the aluminum busbar 1 under stress. Aluminum ports 4 are provided at both ends of the aluminum busbar 1. The aluminum ports 4 are formed by bending the ends of the aluminum busbar 1 outwards and connecting to the aluminum busbar 1 at right angles. The aluminum ports 4 are formed by bending, creating independent connection areas at the ends for connection with other conductive components. After aluminum port 4 and aluminum busbar 1 are arranged at a right angle, the conductor connection direction can be changed, allowing the entire conductor structure to adapt to electrical connection requirements in different directions. A connection-side slot 5 is provided at the connection between aluminum busbar 1 and aluminum port 4. The connection-side slot 5 is located in the transition area between aluminum busbar 1 and aluminum port 4, forming a locally thinned structure in this area. During bending or under stress, some stress can be released, thereby reducing the possibility of deformation or cracking at the connection point. By setting the connection-side slot 5 structure, a more stable transition structure can also be formed in the bending area. Pure nickel strips 6 are attached to the outer surfaces of both aluminum ports 4, covering the outer surfaces of aluminum ports 4, forming a nickel layer coverage structure in the port area, thereby forming a stable conductive contact layer on the surface of aluminum port 4. Since nickel material has good oxidation resistance, it can reduce the problem of surface oxidation of aluminum port 4 during long-term use. The pure nickel strip 6 is fixedly connected to aluminum port 4 by hot-press welding. The hot-press welding method forms a stable bonding structure between the pure nickel strip 6 and aluminum port 4, allowing the pure nickel strip 6 to be firmly attached to the surface of aluminum port 4. The connection structure formed by hot-press welding can reduce the contact gap between two metals, thus forming a more stable conductive connection structure between them.

[0018] A pure nickel strip 6 is disposed on the outer surface of the aluminum port 4. After the pure nickel strip 6 is disposed on the outer surface of the aluminum port 4, a metal covering structure is formed in the port area, thereby forming a stable contact interface when the area comes into contact with external conductive components. This structure can reduce the area of ​​the aluminum port 4 directly exposed to the air. The connecting side slot 5 is set as an arc-shaped slot structure. The arc-shaped structure can form a smooth transition contour at the bottom of the slot, thereby reducing the formation of sharp corner structures at the edge of the slot. The arc-shaped slot structure can reduce local stress concentration. The connecting side slot 5 is set through the thickness direction of the aluminum busbar 1. When the slot penetrates the thickness of the aluminum busbar 1, the slot structure forms a through structure, thereby forming a clear structural separation area in the connection transition area. This through-structure allows the bending area to form a certain structural buffer space when under stress. The central bending area 3 is set as an arc transition structure, which can avoid sharp corners at the bend, thereby reducing the possibility of cracks in the material during bending. This structure can also make the bending area form a more uniform stress distribution when under stress. The central bending area 3 is located in the middle of the length direction of the aluminum busbar 1. Setting the central bending area 3 in the middle of the aluminum busbar 1 can keep the structure at both ends of the aluminum busbar 1 symmetrical, so that the entire conductor structure maintains a stable layout during installation. This structure also facilitates the installation and connection of conductors between different devices. The insulation layer 2 is covered and set on the outer surface of the aluminum busbar 1. After the insulation layer 2 is covered, it forms electrical isolation between the main body of the aluminum busbar 1 and the external structure, thereby reducing the safety risks caused by exposed conductors. This structure can also reduce the direct contact between the aluminum busbar 1 and external metal parts. The insulation layer 2 forms an opening structure at the two aluminum ports 4. By forming an opening at the port, the aluminum port 4 area is kept exposed, thereby facilitating welding or connection operations in this area. This structure ensures that the insulation layer 2 does not interfere with the connection of the aluminum ports 4. The two aluminum ports 4 are respectively located at both ends of the aluminum busbar 1. Positioning the ports at both ends of the aluminum busbar 1 creates a two-end connection for the entire conductor structure, allowing for connection to different conductive structures. This structure facilitates series connection between conductors. The two aluminum ports 4 are centrally symmetrical with respect to the aluminum busbar 1. The pure nickel strip 6, located inside the insulation layer 2, is partially embedded within it. This embedding of the pure nickel strip 6 within the insulation layer 2 creates a covering relationship, reducing the area of ​​the pure nickel strip 6's directly exposed edge. This structure allows the pure nickel strip 6 to maintain a more stable installation at the aluminum ports 4. Both the pure nickel strip 6 and the aluminum ports 4 have connection holes, allowing external fasteners to pass through these holes, thus securing the aluminum ports 4 to the external structure.
