The invention discloses a stepped heat-shrinkable terminal. The terminal comprises a double-wall tube, inner walls of the double-wall tube are connected with hot-melt adhesive layers, the middle of the double-wall tube is provided with a bare terminal body, the inner walls at two ends of the double-wall tube are connected with slide rails arranged in symmetry, the slide rails are connected with slide plates in a sliding manner, first push plates are vertically welded at one sides, far from the bare terminal body, of the slide plates, sidewalls at one sides of the slide plates are provided withfirst channels along the length direction, sidewalls of two sides of the first channels are provided with first grooves, sidewalls of the first grooves are connected with telescoping rods, the otherends of the telescoping rods are connected with arc plates, and second push plates are vertically welded at sidewalls of one sides of the telescoping rods. According to the terminal, two ends of the terminal are respectively accessed to products of different wire sizes and are sealed and fixed, joints of wires can be rapidly and conveniently connected, the connection efficiency and quality can begreatly improved, and the practicality of the terminal is improved.
