Laminated Copper Foil Shunt
Products Description
At its core, the Laminated Copper Foil Shunt-a flexible connection utilizing copper foil diffusion welding-distinguishes itself from traditional braided flexible connectors. Its defining feature lies in an integrated manufacturing process involving the stacking of multiple layers of copper foil bonded via diffusion welding. This design harmonizes exceptional electrical conductivity, flexible adaptability, and structural stability, making it widely suitable for meeting the current shunting and connection requirements of various high-voltage, high-current electrical devices. Its primary value lies in its ability to facilitate precise current shunting and signal detection while simultaneously utilizing its flexible structure to absorb vibrations, thermal deformations, and installation misalignments occurring during equipment operation, thereby preventing stress concentration at the connection points.
Core Advantages
Precise Shunting
Utilizing a stacked structure of multiple ultra-thin copper foil layers-where both the thickness and number of layers can be precisely engineered to meet specific shunting requirements-and integrated via a diffusion bonding process for Copper Foil Connector, this design ensures that current shunting ratios are accurate and controllable, free from significant deviation. This provides the equipment's control system with reliable current detection signals, thereby preventing equipment malfunctions caused by inaccurate current shunting.
Flexible Adaptability
The Copper Foil Flexible Storage Energy Battery Busbar exhibits exceptional flexibility and toughness, allowing for multi-angle and small-radius bending. This enables it to accommodate installation tolerances and displacement caused by thermal expansion and contraction. Furthermore, it effectively absorbs vibrations generated during equipment operation, preventing stress concentration at connection points that could lead to fractures or desoldering-thereby resolving the critical issue of poor adaptability inherent in traditional rigid shunting components.
Stable Conductivity
Crafted from oxygen-free copper foil, the Copper Flexible BusBars for Lithium Battery material boasts superior electrical conductivity. The diffusion bonding process fuses the multiple copper foil layers into a monolithic structure devoid of contact gaps, resulting in extremely low contact resistance. This effectively minimizes current transmission losses and prevents localized overheating, ensuring the stability of both current transmission and shunting processes; moreover, the conductive performance remains undiminished even after prolonged use.
Design Advantages
Graded Thickness Transition Zone
Facilitates a smooth transition from the fully bonded state at the diffusion-welded terminal end to the flexible state of the central section. By precisely controlling the temperature gradient within the heating zone, a partially bonded transition zone-spanning 5 to 15 mm in length-is created. This design eliminates abrupt discontinuities in stiffness between the welded and non-welded sections, thereby ensuring a uniform distribution of bending stresses for Copper Foil Multi-Layer Welding Busbar.
Staggered Layer Arrangement
For flexible connectors exceeding 40 mm in width, the foil laminates are divided into 2 to 3 groups, with each group offset by 0.5 to 1.0 mm relative to the others. This arrangement prevents the edges of all laminates from aligning within a single plane, thereby effectively mitigating stress concentration at the edges of Copper Laminated Flexible Connectors.
Pre-Arched Design
For installation scenarios requiring the absorption of axial compressive forces, the flexible connector is pre-formed into an arched shape. This design ensures that the connector possesses a predetermined amount of initial deformation upon installation, thereby further reducing the reaction forces exerted back upon the Copper Foil Connector.
