The invention relates to a quick connector for configuring a cable terminal. A contact end of a metal conductive connection block is in conductive connection with the connection terminal of a cable; an insulation protection shell is arranged on the outer side of the portion, except the contact end, on the metal conductive connection block. A compression block is arranged at the contact end of themetal conductive connection block and closely connected with the connection terminal by wrenching a hexagon socket screw. By means of the quick connector, a quick connection scheme can be quickly, safely and efficiently provided for electrical equipment and lines, quick access of an emergency power supply car is easy, and more time can be gained for emergency maintenance of the electrical equipment and lines.
