I. Product Overview

This conductive contact piece is made by high-elastic phosphor bronze strip material through continuous mold multi-process stamping and bending, with a bottom annular base equipped with positioning clips, which can securely lock in the plastic base to prevent rotation and detachment; several elastic conductive claw pieces extend upwards, relying on the material's own elasticity to clamp the contact points, achieving continuous and stable electrical conduction. The finished product is electroplated with precious metal coating, significantly reducing contact resistance while isolating air to prevent oxidation and discoloration; it maintains its elasticity after tens of thousands of insertion and extraction cycles, serving as the core conductive connection hardware for various small electronic components.

A variety of elastic base materials such as beryllium copper, stainless steel, and brass are available. The ring size, claw quantity, and bending shape can be precisely replicated according to customer drawings or physical samples in a 1:1 ratio; new product samples are verified for elasticity and conductivity, and upon meeting standards, mass production commences with full-process detection and control of elasticity, dimensions, and plating.

Chapter Two: Core Highlights of Craftsmanship

1. Continuous die-casting forming, uniform batch precision
   The entire structure is formed, cut, and bent in one go without segmented welding. All products have minimal elasticity and dimensional deviations, suitable for assembly with automated equipment.
2. Multi-claw elastic holding structure, stable contact with vibration resistance
   Multiple independent claw contacts synchronize, single-point wear does not affect overall conduction; no power interruption or loose connection occurs in vehicle or equipment vibration environments.
3. Ring belt clip limiting base, assembled without slippage
   The outer ring positioning protrusions securely lock the plastic cavity, preventing the contact parts from circumferential rotation and axial ejection, ensuring the assembly position remains firm and unchanged over long-term use.
4. Global polishing + electroplating treatment, excellent conductivity and rust prevention
   The inner wall of the shotshell and the gap of the claw blade are fully coated, which not only ensures an extremely low contact resistance but also resists moisture and oxidation, extending the service life.
