A CONDUCTOR SLEEVE FOR CONNECTING POWER CABLES HAVING DIFFERENT CONDUCTORS, A CONDUCTOR SLEEVE FOR CONNECTING ALUMINUM CONDUCTOR POWER CABLE, A METHOD OF MANUFACTURING THE SAME, AND A JOINT BOX HAVING THE SAME

摘要

PURPOSE: A conductive sleeve for connecting power cables with different conductors, a middle connection box, or a terminal connection box, a conductor sleeve for connecting a power cable with an aluminum conductor, a manufacturing method thereof, and a connection box having the same are provided to improve corrosion resistance and mechanical intensity by forming the connection part of a conductive sleeve with a copper material. CONSTITUTION: The accommodating groove accepting a first conductor is formed in one side of a sleeve(230). A body(232) with a junction portion(232a) is formed in the other side of the sleeve. A welding unit(235b) is connected by welding the second conductor of an aluminum material. A first power cable and a second power cable include the first conductor and the second conductor of a copper material and the aluminum material. The conductive sleeve includes the welding unit which is connected to the second conductor and a second welding method. An insulation unit insulates the first and the second power cable. A protection pipe protects the outside of the insulation unit.
