  • Patent number: 6558183
    Abstract: A plug connector (1) includes a casing (10), a mating portion (30) retained by the casing for mating with a mating connector, a pair of lock members (61) and a pair of release buttons (62). The lock members are fixed in the casing. The lock members each include a resilient lock arm (611). A pawl (612) extends from an end of each lock arm for engaging with a corresponding part of the mating connector. The release buttons are separately made and are pivotally mounted in the casing. The release buttons each include an actuating protrusion (622) for engaging with the lock arm of the lock member. The release button is operable to deflect the lock arm by the actuating protrusion for disengaging the pawl from the corresponding part of the mating connector.
