Patent ID: 8226432

Claim:
A Serial Advanced Technology Attachment (SATA) electrical connector for mating with a complementary electrical connector which has an insulator defining a lateral slot with two opposed sides, one of which is formed with a longitudinal guiding slot perpendicularly communicated with the lateral slot and is arranged with a plurality of first-type terminals and a plurality of second-type terminals located beside the longitudinal guiding slot, the SATA electrical connector comprising: a mating insulator having a base, a lateral rib protruding from a base surface of the base, a plurality of first-type mating terminal holes and a plurality of second-type mating terminal holes formed on the base, and a plurality of first-type mating terminal slots and a plurality of second-type mating terminal slots formed along the outer circumferential side of the lateral rib, wherein the lateral rib forms an outer circumferential side with two opposed ends terminated beside the lateral rib and matches with the lateral slot of the complementary electrical connector; a plurality of first-type mating terminals each having a flat portion which is inserted into the corresponding first-type mating terminal hole to protrude beyond the corresponding first-type mating terminal slot; and a plurality of second-type mating terminals each having a flat portion which is inserted into the corresponding second-type mating terminal hole to protrude beyond the corresponding second-type mating terminal slot, wherein a distance between the flat portions of the adjacent first-type mating terminals protruding beyond the corresponding first-type mating terminal slots is different from a distance between the flat portions of the adjacent second-type mating terminals protruding beyond the corresponding second-type mating terminal slots.
