Abstract

A power connector includes an insulated housing and at least one electrical terminal assembly. The insulated housing has at least one terminal receiving hole. The at least one electrical terminal assembly is inserted in the at least one terminal receiving hole. Each electrical terminal assembly has an inner terminal, and an outer terminal. Each inner terminal has a connecting section, and an elastic section connected to the connecting section. Each outer terminal has a conductive portion, a leg portion arranged at one end of the conductive portion, and a curve portion arranged between the conductive portion and the leg portion. The leg portion is exposed outside of the insulated housing. The connecting section of the inner terminal is fixedly connected to the conductive portion of the outer terminal. The present disclosure further has an electrical terminal assembly.
