Latching Relay Copper Braid

Design Advantages

High Customization Capability: We can flexibly customize the braided layer length, cross-sectional area, terminal type, and shape according to your relay's internal space, current rating, and bending radius requirements, perfectly fitting your design.

Integrated Solutions: We can provide finished assemblies with insulating sleeves (heat shrink tubing, silicone tubing) and can even pre-assemble them with other components to provide you with ready-to-use modules.

Materials Science and Structural Advantages: Ingenious Construction from Micro to Macro

1. The Core Value of High-Purity Oxygen-Free Copper:

Material Depth: We rigorously select high-purity oxygen-free copper as our raw material. Its extremely low oxygen content (<0.001%) ensures that the Pure Copper Braid will not suffer from "hydrogen slag" during subsequent processing and use-that is, micro-cracks caused by the reduction of copper oxide in a reducing atmosphere. This guarantees extremely high conductivity (≥100% IACS) and long-term ductility and toughness, laying the molecular foundation for the product's long lifespan.

2. The Structural Philosophy of Multi-Strand Ultra-Fine Wire Braiding:

Structural Depth: Compared to using coarse Bare Copper Braid, we intertwine hundreds or even thousands of ultra-fine, soft copper wires into bundles using a precision braiding machine. This design brings fundamental advantages:

Extremely Large Specific Surface Area: Under the same current-carrying capacity, the braided structure has a surface area several orders of magnitude larger than solid conductors, which facilitates heat dissipation and effectively reduces temperature rise.

Exceptional Flexibility: The tiny gaps between the filaments allow them to slide against each other, enabling the overall structure to withstand tens of thousands, even millions, of high-frequency bends without hardening cracks.

Superior Fatigue Resistance: Stress is evenly distributed across each Copper Braid for Latching Relay, avoiding single-point stress concentration, resulting in a fatigue life far exceeding that of solid conductors and stranded wires.

3. Customized End-End Treatment Technology:

Structural Depth: The flexibility of the braided layer itself must be combined with reliable end-end connections. We offer a variety of end-to-end treatment solutions, including precision squaring, ultrasonic welding, brazing, and tin plating. By precisely controlling pressure, temperature, and time parameters, we ensure that the conductivity and tensile strength of the end-end connection area are close to that of the Flexible Copper Wire for Latching Relay layer itself, forming a perfect transition from flexibility to rigidity and eliminating the weakest link in the system.
