A connector soldered to a PCB has an insulating housing of which two opposite ends recessed to form a pair of fixing recesses, terminals mounted in the insulating housing having soldering portions projected out of a bottom of the insulating housing, a latch member and a positioning member. The latch member has a base slice inserted in the fixing recess. A top of the base plate extends sideward and then is bent downward to form a folded plate apart facing the base plate to define an interval therebetween. The positioning member movably mounted to the latch member has a base slice inserted in the interval and a soldering slice perpendicularly connected at a bottom of the base slice for being soldered with the PCB. The base slice of is capable of moving up-and-down in the interval to adjust the soldering slice to be level with the soldering portions.
