Abstract

A conductive component structure of electrical wire connection device is more securely assembled with the conductive wire to enhance the electro-conduction performance. The conductive component includes a main body in the form of a plate body, a restriction body connected on the main body and an aid unit (or elastic unit) assembled with the restriction body. The restriction body has a base section, a first arm and a second arm connected with the base section and free sections connected with the first and second arms. The aid unit (or elastic unit) provides greater elastic holding action force for the restriction body. When the conductive wire is plugged into the case into contact with the conductive component, the rear end of the conductive wire is at least securely pressed between the first and second arms of the restriction body without deflecting or swinging due to external force.
