I. Product Overview

This elastic output electrode is made of high-quality H62 brass strip, formed by continuous mold stamping and bending into one piece. The side of the base plate is stamped with anti-slip teeth, with one end bent to form an L-shaped elastic contact arm; the base plane can be welded or embedded into the internal plastic shell, where the teeth pattern securelyocclusion the inner wall of the plastic, preventing the electrode from rotating and falling off. The bending spring relies on its own elasticity to continuously press on the contact point, ensuring stable current transmission. The finished product is electroplated with gold, with a dense precious metal coating on the surface to isolate air and moisture, completely avoiding oxidation of the copper material, which would cause increased contact resistance and heat generation during electrical conduction, suitable for long-term electrical conduction conditions of various rechargeable devices and portable electronic power supplies.

High elasticity base materials such as phosphor bronze and beryllium copper can be selected as required. Sheet sizes, bending radii, and sawtooth arrangements can be 1:1 replicated from customer drawings or physical samples. New product samples are tested for elasticity and conductivity. After all indicators meet the standards, mass production is initiated, with full inspection and control of elasticity, coating thickness, andAppearance dimensions upon shipment.

II. Core Highlights of Craftsmanship

1. Continuous mold integrated stamping and bending, long-lasting elastic life
   The entire structure is cut, notched, pressed, and bent into shape in one step without any splicing or welding. The stress at the bending points is fully released, and the elasticity remains stable and firm after tens of thousands of compressions and rebounds.
2. Side-tooth interlocking structure, embedded plastic never comes loose
   The baselines are injection-molded with teeth around the edges, pre-buried to a certain depth, and securely engaged with the plastic, which prevents rotation and extraction under load, achieving a much higher assembly firmness than smooth flat electrodes.
3. L-shaped elastic cantilever design, adaptive fit contact point
   Bent spring strips feature moderate buffering allowance, capable of adapting to minute contact tolerances, maintaining tight fit in equipment vibration environments, and preventing power interruption and loose connection faults.
4. Full-surface gold plating, dual protection of conductivity and rust prevention
   The front and back of the splinters and the edges of the gaps are fully covered with gold plating, featuring extremely low contact resistance, resistance to salt mist and oxidation, and stable operation in humid environments.
