I. Product Overview

This multi-step stepped electrode features high-quality conductive metal rod material, precision turned and integrated into one piece by CNC centerless grinding machine, with multi-step limiting steps, front plug-in stepped heads, and rear locking external threads formed in one go, without welding or secondary assembly. The finished product is bright nickel plated, with a dense plating layer effectively isolating air, preventing oxidation and discoloration of the base material, and maintaining a stable low contact resistance over a long period. The front multi-step stepped structure can be precisely mated with the matching sockets; the middle annular flange stepped surface controls the assembly depth accurately, ensuring consistency in batch assembly; the rear external thread facilitates the tight fixing of terminal blocks and wires, making it a stable power and signal output conductive component for various electrical equipment.

Available in a variety of raw materials such as brass, phosphor bronze, and stainless steel, the electrode diameter, total length, step layout, and thread specifications can be customized according to customer drawings and physical samples. Both small batch trials and long-term mass production supply can be undertaken, with full inspection and control of finished product dimensions and surface coatings.

Part Two: Core Highlights of Craftsmanship

1. CNC integrated turning and shaping, high coaxiality, smooth assembly
   The rod body, limit step, plug-in end, and tail thread are all precision machined as a whole, featuring excellent concentricity. The mating process with the matching socket is smooth without jamming, ensuring long-term assembly accuracy.
2. Multi-level stepped interlocking structure, increasing the conductive contact area
   Front-end multi-stage cylindrical stepped design, achieving foolproof precise connection, effectively increasing the conductive contact area, and reducing the risk of false connection and overheating under high current conditions.
3. Circular limit step, unified assembly insertion stroke
   Integrated circular steps serve as assembly reference, accurately limiting electrode insertion depth, preventing over-positioning assembly, and significantly reducing debugging workload in mass production.
4. Overall bright nickel plating treatment, anti-corrosion and anti-oxidation
   Uniformly bright nickel coating covers the entire surface, with complete plating at gaps and step positions, strong rust and oxidation resistance, suitable for long-term electrically connected environments indoors and under slight humidity.
