Patent attributes
An electrical connector includes an insulated housing and a plurality of contact loaded in the insulated housing. The insulated housing defines an uninterrupted longitudinal slot extending in a first direction and through a mating face in a second direction perpendicular to the first direction the slot having a first and a second inner side faces facing to each other. The first inner side defines a groove extending through the mating face in the second direction. Each contacts includes a retaining portion retained in the insulated housing, a contacting portion exposing in the slot and a tail portion. The contacting portions defines a mating orientation along which the contacting portions contact with corresponding contacts of a counter electrical connector intended to be inserted in the slot. The plurality of contacts includes a first group and a second group of contacts lined along the first side face of the slot at opposite sides of the groove, and a third group, a forth group and a fifth group of contacts lined along the second side face. The third group of contacts are aligned with the groove, the forth group of contacts faces to the first group of contacts and the fifth group of contacts faces to the second group of contacts in a third direction perpendicular to the first and second directions.
