The tensile strength of the terminal mainly depends on the contact pressure between the terminal and the wire. The contact pressure is mainly provided by the elastic deformation and plastic deformation of the terminal and the wire. An important factor that determines the elastic deformation and plastic deformation of the terminal and the wire is the crimping height. .
The smaller the contact height, the greater the pressing force, the greater the elastic-plastic deformation of the terminals and wires, the greater the contact force, and the greater the tensile strength. The higher the pressing height, the smaller the pressing force, the smaller the elastic-plastic deformation of terminals and wires, the smaller the contact force, and the smaller the pulling force.
