Patent ID: 8292675

Claim:
An electrical connector for insertion of a first plug along a mating direction, comprising: an insulative housing comprising an opening, a receiving cavity and at least one blocking member provided in the receiving cavity, said at least one blocking member comprising a guiding portion adjacent to the opening, and a resilient portion projecting more inwardly to the receiving cavity along a transverse direction, which is perpendicular to the mating direction, than the guiding portion, to thereby form a shoulder portion facing to the opening between the guiding portion and the resilient portion, said resilient portion being deformable sidewardly along the transverse direction; and a contact module assembled to the insulative housing, wherein said shoulder portion of the at least one blocking member is formed with a first corner and the first plug is formed with a second corner, the first corner of the shoulder portion being resisted against by the second corner of the first plug to deform the resilient portion sidewardly along the transverse direction, for permitting the first plug inserting into a final position within the receiving cavity, wherein there are a pair of said blocking members, said pair of blocking members and the insulative housing being formed into a whole, wherein said insulative housing comprises a pair of side walls, the guiding portion of each blocking member comprising a root portion connected with the side wall, and a platform between the root portion and the resilient portion, wherein said resilient portion is separated from the side wall to form a deforming space between the resilient portion and the side wall, said resilient portion being deformable in the deforming space, wherein said pair of platforms of the pair of blocking members have a first distance therebetween, a first width of the first plug being not larger than said first distance, and larger than a distance between said pair of resilient portions, said first plug sliding over the shoulder portions to the final portion via the corporation between the first and second corners, wherein said shoulder portions of the pair of blocking members block an insertion of a second plug having a second width larger than both the first width and the first distance.
