Patent ID: 8133070

Claim:
A SATA (Serial Advanced Technology Attachment) electrical connector comprising: an insulator having a lateral rib protruding from a base surface of the insulator to laterally form two opposed free ends beside the lateral rib, and a longitudinal guiding portion extending outside the lateral rib from an outer side formed on an outer circumference of the lateral rib to form a free end opposite to the lateral rib; a signal terminal group having a plurality of signal terminals, a flat portion of each signal terminal being inserted into a signal terminal hole of the insulator; a power supply terminal group having a plurality of power supply terminals, a flat portion of each power supply terminal being inserted into a power supply terminal hole of the insulator; a cable having a first wire group and a second wire group, wires of the first wire group and the second wire group being respectively connected to the signal terminals and the power supply terminals; and a metallic housing clasped to a base of the insulator, wherein the flat portions of the signal terminals protrude beyond signal terminal slots formed on the outer side of the lateral rib, and the flat portions of the power supply terminal protrude beyond power supply slots formed on the outer side of the lateral rib, wherein the guiding portion is located between the signal terminal group and the power supply terminal group.
