Connector terminals, EMI shielding, stamped, and over-molded busbars are essential components in power electronic devices. NN Inc.’s manufacturing capabilities enable us to provide the precision components required for power inverters, DC/DC converters, on-board chargers, induction motors, power distribution, wire harnesses, and accessory modules.
Explore a spectrum of devices that use components that NN manufactures.
Power inverters are used to convert high-voltage DC to 3-phase AC power needed to drive AC induction and traction motors. NN can manufacture the custom EMI connector shields, high-voltage terminals, and over-molded bus bars required in AC/DC inverters.
DC/DC converters play a critical role in adjusting the voltage level from the high-voltage battery to the required levels for various components in electric vehicles and energy storage systems. NN offers manufacturing expertise in producing essential components such as bus bars, connector terminals, and shields necessary for the efficient operation of these converters.
On-board chargers convert AC power from a level 1 or 2 EV charger to the high-voltage DC required to charge the battery pack. NN can manufacture the bus bars, connector terminals, and shields.
High-voltage battery packs store power for EVs or energy storage installations using either cylindrical, prismatic, or pouch formats. NN can manufacture the bus bars, collector plates, and connectors for all battery formats.
Induction and Traction Motors are part of EV powertrains, utilizing AC power to propel electric vehicles. NN can manufacture bus bars, connectors terminals, and shields.
Power distribution is a part of the battery pack or individual devices used to manage power in electrical systems. NN can manufacture custom EMI connector shields, high-voltage terminals, bus bars, and over-molded bus bars.
Wire harnesses consist of shielded and unshielded cables with connectors to connect all devices in an electrical system. NN can manufacture custom EMI connector shields and high-voltage terminals.
Accessory modules are secondary devices that use high-voltage DC to heat or cool the EV cabin and battery packs. NN can manufacture custom EMI connector shields, high-voltage terminals, and over-molded bus bars.
In the high-voltage electrical industry, NN Inc. specializes in crafting essential components such as stamped connector shields, stamped terminals, and busbars. These key parts, fabricated from diverse materials and utilizing a variety of finishes, ensure the safe and efficient flow of electricity in various systems.
Stamped terminals play a vital role as integral components of high-voltage connectors, enabling the efficient flow of electricity between the device and the cable. NN possesses extensive knowledge and capability to produce both male and female terminals. Our expertise extends from simple terminal tabs to more complex box and circular terminals. We offer stamping services for terminals in steel, aluminum, and copper, with options for full plating, selective plating, or no plating.
Stamped box EMI shields are vital components in shielded electrical systems, particularly for high-voltage connectors. These shields play a crucial role in reducing electromagnetic interference at connection points, safeguarding critical electronics from emissions. They facilitate the interface between shielded cables and electrical devices, ensuring the flow of electric current remains shielded. NN offers manufacturing of stamped shields in copper or steel, available with plating or un-plating options.
Stamped bus bars play a critical role in facilitating the efficient flow of electricity throughout systems. They are utilized in various devices to distribute high-voltage electricity, particularly in tight spaces where the use of wires and connectors is impractical. Additionally, over-molded bus bars provide further versatility and functionality in such applications.
NN Inc. possesses extensive engineering experience in precision machining, stamping, and injection molding, making us well-suited for the manufacturing of terminals, shielding, busbars, and molded components used in electric vehicles and charging infrastructure.
