As the crimped piece of hard metal is strongly pressed against the stranded wire conductor by a strong crimping force, the twist configuration of the stranded wire group collapses, and the stranded wire group is plastically deformed by the crimping force, reducing mechanical properties. However, it may be damaged or disconnected, resulting in loss of electrical continuity.
