Claim 1

A USB electrical connector, comprising: an insulative seat body having a planar top wall and a protrusion projecting upwardly from said top wall; a plurality of terminals mounted on said seat body; and a metal shell snugly receiving said seat body and having a front open end for insertion of said seat body, and a planar top wall which has an opening adjacent to said front open end to interlock with said protrusion, a slit that extends from said front open end to said opening along a line parallel to the direction of insertion of said seat body to communicate with said opening, and two opposite resilient anchor plate portions that extend between said front open end and said opening on two opposite sides of said slit, said anchor plate portions being flexible to prevent permanent deformation of said metal shell due to pushing by said protrusion when said seat body is inserted into said metal shell; and wherein, said planar top wall of said metal shell further has two opposite edges extending in the direction of insertion of said seat body and bounding said opening, each of said anchor plate portions having an elongated cut communicating with and extending forwardly from said opening toward said front open end along a line extending from an adjacent one of said edges, and a neck extending between said cut and said front open end.
