Abstract: An electrical connector comprises a dielectric housing, a number of terminals received in the housing, an insulative spacer and a retainer supportingly attached to the spacer. The terminals each comprise a base, an engaging end forwardly extending from the base, a neck rearwardly extending from the base, and a shoulder intermediate the neck and a leg for mating with a circuit board. The spacer includes a number of uniformly spaced apart dividers, each divider defining a pair of channels at rear corners thereof whereby defining a pair of rearwardly facing abutment walls. The dividers are interposed between the necks of adjacent terminals thereby the abutment walls bear against the shoulders of the terminals for preventing their forward movements.
