Abstract: A DC power output insert connector assembly of a power supply includes: a fixed base; insert connectors coupled with the fixed base, each including terminal slots; and conducting plates, each including at least one conducting terminal and a connecting terminal extended from an end of the conducting terminal, and the conducting plate is coupled with the fixed base and the insert connector, such that the conducting terminal is installed into the terminal slot and the connecting terminal is exposed from the fixed base. With the assembly of the fixed base and the insert connectors, and the conducting plate, the DC power output insert connector can be manufactured easily, and the manufacturing time and cost can be lowered. The invention also waives the soldering operation to comply with the environmental protection requirements, so as to lower the manufacturing and assembling costs and improve the competitiveness of the product.
