DC High Voltage Row Header

A DC High Voltage Row Header is a specialized connector designed to safely handle high-voltage DC currents, commonly used in electric vehicles, battery systems, and industrial power electronics.OverviewDC high voltage row headers are connectors that provide secure, reliable connections for high-voltage DC circuits. They are designed to handle voltages ranging from several hundred volts up to 100 kV in some specialized applications, with current ratings typically from tens to hundreds of amperes depending on the design and application . These headers are critical in systems such as battery packs, DC/DC converters, and hybrid or electric vehicle powertrains .Key FeaturesVoltage and Current Ratings: High-voltage headers are rated for safe operation at high DC voltages, often up to 100 kV for specialized connectors, with current capacities from 30A to 350A depending on the connector type .Safety and Insulation: Many high-voltage headers feature recessed or shielded contacts to prevent accidental contact and reduce the risk of electrical shock. PTFE insulation and oil-tight versions are available for harsh environments .Mechanical Design: These connectors often include screw interlocks, clip locks, or friction-lock systems to ensure secure mating and prevent accidental disconnection . Some designs allow for multiple mounting options, including feedthrough, surface, or panel mounting.Material and Durability: Silver-plated or gold-plated contacts, nickel-plated housings, and robust cable glands provide low-resistance connections and long-term reliability .Customization: Manufacturers like Rosenberger and TE Connectivity offer custom solutions for battery modules, Y-splitters, busbars, and cell module connectors, allowing precise adaptation to vehicle or industrial architectures .ApplicationsElectric and Hybrid Vehicles: Connecting battery modules, DC/DC converters, and high-voltage power electronics .Industrial Power Systems: High-voltage DC distribution, charging stations, and energy storage systems.Laboratory and Instrumentation: High-voltage testing setups and nuclear instrumentation modules using SHV or MHV connectors .Manufacturers and OptionsTE Connectivity: Offers a broad line of high-voltage connectors and headers for hybrid and electric vehicles, emphasizing safety, efficiency, and reliability .Rosenberger: Provides custom high-voltage components, including cell module connectors, Y-splitters, and busbars, optimized for low-loss performance and long-term reliability .Hivolt: Supplies standard high-voltage connectors for up to 100 kV DC, including single and multi-pin designs, with options for shielded cables and hermetic sealing .Design ConsiderationsWhen selecting a DC high voltage row header, consider:Maximum operating voltage and currentEnvironmental conditions (temperature, moisture, vibration)Safety features (recessed contacts, interlocks, insulation)Compatibility with cable sizes and mounting requirementsRegulatory and agency approvals for automotive or industrial use These connectors are essential for ensuring safe, efficient, and reliable high-voltage DC connections in demanding applications.
