A connection terminal technology for aluminum wires that solves four challenges!
The "Convex Serration" is a crimp terminal for aluminum wires that achieves a good connection by having the convex parts peel off the coating. By embedding the convex parts into the aluminum material, it isolates the areas with high stress from other less stressed areas. This concentrates stress in a closed region, maintaining the repulsive force (internal stress) at the contact boundary and preventing stress relaxation (cold flow). 【Features】 ■ A square pyramid shape with equal lengths on all four sides ■ Protruding serrations with an angle of inclination between 45 and 75 degrees ■ Multiple independent areas continuously formed surrounded by four protrusions *For more details, please download the PDF or feel free to contact us.

basic information
**Solutions to Four Challenges** ■ Electrolytic Corrosion - Prevents electrolytic corrosion by crimping aluminum wire to a strain rate that reaches the complete plastic region, forming a Sn-plated terminal and alloy layer. ■ Oxide Coating - Destroys the oxide film by providing protruding serrations at the crimped part of the terminal. - Achievable by forming multiple protruding shapes in a square pyramid configuration. ■ Strength Reduction - Prevents a decrease in tensile strength by providing protruding serrations inside the terminal to limit deformation to the necessary minimum amount. ■ Stress Relaxation - Prevents stress relaxation by providing protruding serrations at the crimped part of the terminal, which isolates areas of high stress from those of low stress, concentrating stress in the confined area. *For more details, please download the PDF or feel free to contact us.*
