Abstract: An electrical connector for use with a circuit board mainly comprises an insulative housing having a bottom wall which integrally defines therein a receiving portion consisting of a first cavity and a second cavity. A board locking means received within the receiving portion of the housing, includes a base which is integrally formed with a plurality of first attachment portions for retaining the base in the second cavity in a basic status. A pair of retention portions extend downward from the base for elastically latching with the circuit board. A pair of spaced extensive arms each extending downward from the base, integrally form thereon a second attachment portion for retention within the first cavity thereby orienting and retaining the board locking means in the receiving portion of the housing in an enhancement status. A second space further separates the extensive arms from the retention portions thereby reducing a mutual effect in the spatial relationship therebetween.
