Conductive terminal and electrical connector
A conductive terminal and an electrical connector are disclosed. The conductive terminal comprises a mating portion positioned at a front end, a tail portion for connecting a conductive wire and a fixed portion connected between the mating portion and the tail portion. Wherein the fixed portion comprises a bottom wall, two side walls bent upwardly respectively from two sides of the bottom wall, a lock tang obliquely extending rearwardly and upwardly from the middle of the bottom wall and two stopping protrusions protruding inwardly from the two side walls, the two stopping protrusions abut against the lock tang so as to prevent the lock tang from being improperly deformed due to a force applied. The present invention can assure that the conductive terminal is firmly fixed in insulative body of the electrical connector.
