1. Field of the Invention
The present invention relates to an electrical connector, and more particularly to an electrical connector having metal shell with a retaining tab creating an interengagment between the metal shell and the housing retaining tab formed by the metal shell.
2. Description of the Related Art
U.S. Pat. No. 8,021,187 issued to Tagawa et al. on Sep. 20, 2011, discloses an electrical connector mating with a cable assembly for transmitting LVDS (Low-Voltage Differential Signaling) signal. The electrical connector includes an insulative housing, a plurality of terminals retained in the insulative housing and a metal shell covering on the housing. The terminals are arranged in a longitudinal direction in which the insulative housing extending. Each of the terminals has a retaining portion, a contacting portion extending from one end of the retaining portion in a mating direction perpendicular to the longitudinal direction and a soldering portion extending out of the insulative housing from another end of the retaining portion. The metal shell includes a body portion surrounding the insulative housing and a plurality of engaging holes extending from end edge of the body portion. The insulative housing has a plurality of engaging projections provided on an opening end edge thereof and inserting into the engaging hole.
The insulating housing and the metal shell are interlocked to each other in the longitudinal direction and a vertical direction orthogonal to the mating direction by inserting the engaging projection into the engaging hole so that rigidity is largely increased. The anchoring mechanism of the insulating housing and the metal shell do not project inside the insulating housing so that it is possible to reduce the height and make pitches fine. However, when the metal shell is mounted on the insulative housing, the engaging holes and the engaging projections are not easily disposed arranged in alignment with each other.
Therefore, an improved electrical connector is desired to overcome the disadvantages of the related arts.
