Claim Text:
1. An electrical connector comprising: an insulative housing including a pair of longitudinal walls and a pair of transverse walls to commonly define therein an elongated plug-receiving cavity along a longitudinal direction, each of said longitudinal walls defining an interior surface facing toward the plug-receiving cavity in a transverse direction perpendicular to said longitudinal direction, said plug-receiving cavity upwardly communicating to an exterior in a vertical direction perpendicular to both said longitudinal direction and said transverse direction; two rows of contacts disposed in the housing with contacting sections extending along the vertical direction on the corresponding interior surfaces, respectively, each of said contacting sections defining a candy-cane configuration viewed in the longitudinal direction with an upper portion defining an upside-down U-shaped configuration straddling an upper ledge of each of the longitudinal walls with a tip region exposed upon an exterior surface of the corresponding longitudinal wall; and each of said contacting sections defining a thickness, along said transverse direction, of which a portion is hidden under the interior surface and the exterior surface of the corresponding longitudinal wall; wherein each of said longitudinal walls defines a plurality of grooves, in the corresponding interior surface, each of said grooves located between two corresponding contacting sections of the corresponding adjacent two contacts; wherein two opposite side edges of the contacting section of each of said contacts, which are partially exposed upon the corresponding interior surface and to the exterior, face respectively toward the neighboring grooves in generally the longitudinal direction; wherein each of said grooves defines a cross-sectional recessed structure along an extension direction; wherein each of said grooves, having a uniform depth, extends along the interior surface from the upper ledge of each of the longitudinal walls and terminates at a bottom surface of the plug receiving cavity; wherein the exposed side edges of the contacting section extend along the interior surface from the upper ledge of each of the longitudinal walls and terminate at said bottom surface of the plug receiving cavity.
