Copper Braided Wire
Products Description
Copper braided wire is made of multiple strands of bare copper wire or tin-plated copper wire, precisely braided in multiple passes to form a mesh structure, possessing excellent flexibility and constant conductivity.
It plays the following key roles within a latching relay:
As part of the coil's conductive circuit, it maintains low impedance characteristics, improving the relay's holding efficiency ratio.
As a flexible compensating connector, it resists micro-displacements caused by mechanical vibration and changes in the coil's magnetic field.
In high-frequency operating scenarios, it achieves continuous and stable current transmission, extending the overall lifespan of the relay.
It avoids the problems of easy breakage and fatigue associated with traditional single-wire or solid-wire structures.
This is a professional connection component designed for high-reliability relay systems, significantly enhancing overall system consistency and long-term lifespan performance.
Main Functions: Four Core Missions Beyond Conductivity
Low Impedance Energy Path
Provides a near-zero-loss current path for the instantaneous start-up of the relay coil. Its excellent conductivity and large cross-sectional area design ensure rapid and efficient energy transfer, which is the fundamental guarantee for the relay's stable and rapid state switching.
Signal Fidelity Transmission
In complex relay modules integrating control or feedback signals, the braided wire structure effectively suppresses high-frequency noise and electromagnetic interference (EMI), ensuring the purity and integrity of control signals and preventing false triggering.
Mechanical Stress Buffering and Isolation
This is its core advantage over traditional wires. The flat copper braided wire acts like a precision mechanical spring, effectively absorbing and buffering vibrations and impacts from the external environment, as well as the mechanical stress from the relay itself during operation, protecting the solder joints and internal coil from damage and greatly extending the relay's mechanical life.
Core Component for Thermal Management
Although latching relays have low power consumption, the coil still generates heat during switching. The excellent thermal conductivity of copper, combined with the larger surface area of the twisted copper wire, can quickly conduct and dissipate heat from the core area of the coil, avoiding material ageing or performance drift caused by local overheating.
Precision Manufacturing Process: Guarantee of Quality
Oxygen-Free Copper Wire Braiding Technology
We use high-purity oxygen-free copper wire with a diameter of 0.10mm-0.15mm, forming a mesh structure through a precision braiding process. The diameter tolerance of each twisted copper wire is controlled within ±0.01mm, ensuring the uniformity of the braided structure and the consistency of conductivity, providing a stable electrical connection for latching relays.
Professional Tin Plating Process
We employ advanced chemical tin plating technology to ensure a uniform plating layer with strong adhesion. The tin plating layer thickness is controlled between 0.5-1.0μm, ensuring both oxidation resistance and conductivity. The tin-plated copper braided wire maintains stable performance within a temperature range of -40℃ to +125℃, adapting to various industrial environments.
Strict Quality Control System
From raw material procurement to finished copper stranded wire delivery, we implement the ISO 9001 quality management system. Each batch of products undergoes testing for 12 key indicators, including resistivity, flexibility, and corrosion resistance, ensuring stable and reliable product quality that meets industrial application requirements.
