An electrical connector (1) includes a terminal module (32), a metallic shield (31) surrounding the terminal module, an outer dielectric cover (10) surrounding a major portion of the shield and a pair of a latching mechanism (50) attached to the cover. The terminal module includes a mating portion having a number of conductive terminals exposed therein. The shield includes a resilient latching beam (20) having a driving portion (22) and an outwardly latching portion (21). The latching mechanism includes a button (40) for deflecting the driving portion inwardly to urge the latching portion inwardly toward the mating portion, and a spring (46) and a spring assembled to the button and abutting against the shield for providing enough release strength to push the button to a normal position.
