Abstract: An electrical connector assembly has a lower connector (3) and an upper connector (4), the lower and upper connectors having a latch device. The latch device of the upper connector includes a pair of resilient arms (42) at lateral sides thereof with a shoulder portion at an lower end of each resilient arm. The latch device of the lower connector includes a pair of locking arms (32) located correspond with the resilient arms, a pair of locking tips (324) being formed at a top end of each locking arm (32), and a pair of push bars (34) formed as part of an insulative housing of the lower connector and disposed to an outside of the locking arms. In use, the locking tips (324) of the lower connector lock with and form a grounding path with the shoulder portions of the upper connector. Each resilient arm includes a pair of outer resilient plates (421) extending outwardly and a central resilient plate (422) extending inwardly.

Abstract: An electrical connector (10) for engaging with a flexible printed circuit (FPC) comprises an insulative housing (20) defining a central slot (22) therein for insertion of the FPC, a plurality of terminals (30) received within the central slot, and an actuator (40). The insulative housing forms a T-shaped securing portion (26) thereon. The actuator includes a base (42), and an inserting beam (44) and a reinforcing beam (46) respectively depending from the base. The inserting beam and the reinforcing beam are parallel to each other. The actuator defines a T-shaped securing channel (46a), for engaging with the T-shaped securing portion of the housing. The actuator further forms two V-shaped ribs (48) between the base and the reinforcing beam, for reinforcing the mechanical strength of the actuator. When the actuator is inserted into the central slot of the housing, the inserting beam firmly pushes the pre-inserted the FPC against the terminals in the central slot of the housing.
