Copper Braid For Electrical Contact
Products Description
The Copper Braid for Electrical Contact utilizes a pure copper braid structure, offering excellent conductivity and flexibility, adapting to the limited space required for relay installation. The outer white fiberglass insulating tube provides reliable insulation protection and is resistant to high temperatures and aging, suitable for the long-term operating temperature environment of the relay. The cylindrical braid structure ensures a uniform current transmission path, reducing losses during current transmission and improving relay efficiency.
As a key component in Copper Braid for Relay Applications, it handles low-impedance current carrying at rated current while utilizing the flexibility of the braided structure to absorb mechanical displacement and vibration during relay operation, preventing fatigue fracture caused by rigid connections.
Key Selling Points
High-Purity Copper Base Material
Utilizing T2 or higher grade copper wire for braiding, with a copper content ≥99.9%, ensuring excellent conductivity (≥100% IACS) and oxidation resistance, reducing contact resistance and temperature rise.
Cylindrical Braid Structure Advantages
Unlike conventional flat braids, the cylindrical cross-section of the Round Copper Braid facilitates passage through the relay yoke gap, improving space utilization. It also ensures uniform current distribution along the circumference, preventing overheating due to the skin effect at the edges.
Glass Fiber Insulation Protection
The white glass fiber sheath has a temperature resistance rating of H (180℃), possessing excellent flame retardancy, arc resistance, and mechanical abrasion resistance. It effectively isolates the live braid from the relay metal frame, enhancing the overall insulation safety margin.
Integrated Terminal Crimping Process
Precision cold-pressed terminals at both ends form a metallurgical bond with the Copper Stranded Wire braid, ensuring stable contact resistance and a pull-out force ≥50N, eliminating the risk of incomplete soldering or loosening.
Product Technical Advantages
Cross-sectional Resistance Consistency Control
Through closed-loop control of braiding tension and online resistance sampling, the DC resistance dispersion of each batch of Copper Braided Wire is ensured to be ≤3%, avoiding uneven temperature rise in relay batches due to individual differences.
Enhanced Insulation Sleeve Adhesion
A special silane coupling agent pretreatment process enhances the adhesion between the glass fiber sleeve and the Copper Stranded Wire surface, preventing sleeve slippage or detachment after high-temperature aging.
Dedicated Terminal Crimping Die
A dedicated crimping die is developed for relay terminal slots, with crimping height and width tolerances controlled within ±0.05mm, meeting the visual positioning accuracy requirements of automated insertion machines.
Cleanliness Control
The production process of Braided Flexible Wire adheres to IATF 16949 cleanroom standards. Copper wire is immediately braided and encapsulated after degreasing and descaling, preventing relay contact arc erosion caused by impurities.
Application Advantages
Reduced Relay Failures
Flexible Copper Wire for Latching Relay absorbs assembly tolerances, avoiding contact jamming caused by hard connections.
Simplified Customer Assembly
The white insulating tube of the Magnetic Latching Relay Copper Braid comes pre-installed, allowing customers to directly spot weld or screw it in, requiring no additional processing.
Extended Relay Life
Tests have shown that using this product increases the mechanical life of relays by 40% compared to hard copper busbars.
Suitable for Automated Production Lines
The round-coil form of the Round Copper Braid is suitable for automatic cutting machine feeding, improving the efficiency of relay assembly lines.
