Explore our flagship ODM compression connectors, micro-pitch board-to-board headers, energy storage terminals, and liquid connection assemblies engineered for high-density applications.
Electrical compression connectors serve as critical junctions in high-voltage power transmission, industrial power conversion, battery energy storage systems (BESS), and aerospace electrical wiring systems (EWIS). Achieving low contact resistance, high thermal stabilization, and long-term mechanical reliability requires deep material domain expertise and controlled plastic deformation physics.
Micro-asperities on contact surfaces restrict current passage, generating localized resistance. Our compression fittings utilize engineered crimp geometry to achieve gas-tight cold welds, reducing contact resistance below micro-ohm thresholds and preventing micro-fretting corrosion.
Operated across severe thermal ranges (-55°C to +150°C), traditional copper lugs suffer stress relaxation. We utilize high-yield C1100 ETP copper and Beryllium Copper alloys, treated with specialized annealing steps to maintain continuous elastic clamping force.
When joining dissimilar metals (such as copper connectors to aluminum busbars), galvanic potential causes rapid oxidation. Dynalink’s specialized electroplating (matte tin, silver, or gold over nickel barrier) prevents electrolytic corrosion and oxide build-up.

As power electronics shift toward higher energy density, wide-bandgap semiconductors (SiC and GaN), and extreme miniaturization, electrical connection systems must adapt to stricter parameters.
Modern PCB designs demand higher power transmission in smaller footprints. Trends favor sub-1.0mm pitch connectors (e.g., 0.50mm and 0.80mm pitch series) capable of carrying high current without inducing thermal degradation on circuit boards.
To reduce cable harness complexity, automotive and robotics OEMs are adopting hybrid compression connectors that integrate high-voltage power pins alongside high-speed differential signal lines within a single shielded housing.
Global regulations (EU RoHS 3, REACH SVHC, WEEE) require completely lead-free bronze/copper formulas and eco-friendly electroplating processes. Dynalink leads this transition by offering 100% compliant metal alloys.
