Abstract: A female terminal fitting (1) includes a tubular portion (14) to receive a rod-like mating terminal (30). Three contact points are on an inner surface of the tubular portion and achieve point contact with an outer surface of the mating terminal (30). One or more resilient contact pieces (18) resiliently contact the mating terminal (30). The contact points (15) are disposed side by side in an outer circumferential direction of the mating terminal (30) when viewed along a center axis (31) of the mating terminal (30). The contact point in the middle is shifted along the center axis (31) with respect to the contact points on both sides in the outer circumferential direction. The resilient contact pieces (18) resiliently contact the mating terminal (30) between the contact points on both sides and the contact point in the middle in the direction of the center axis (31).

Abstract: An insulating cover that is attached to a terminal block having at least two bus bars and a terminal block-side insulating wall that is provided between the two bus bars. The insulating cover includes a cover-side insulating wall in which a first wall surface faces a first wall surface of the terminal block-side insulating wall; and a connecting wall that strikes the terminal block-side insulating wall and restricts attachment when attempting to attach the insulating cover such that a second wall surface of the cover-side insulating wall faces a second wall surface of the terminal block-side insulating wall.

The front projection (40F) disposed in front of the first contact point includes a front contact point (41F) provided on a projecting end part thereof and a front bead (42F) having a slope approaching the second wall as the slope extends rearward from the front contact point (41F). The rear projecting portion (40R) disposed behind the first contact point includes a rear contact point (40R) on a projecting end part thereof and a rear bead (42R) having a slope approaching the second wall as the slope extends forward from the rear contact point (41R).

Abstract: A device connector (10) is mounted into a mounting hole (C1) on a case (C) of a device in a vehicle, and includes terminals (50) connected to wires (W). A synthetic resin housing (30) includes a wire introducing portion (32) and a fitting portion (31). The wire introducing portion (32) receives the wires (W) and the terminals (50) while the fitting portion (31) fits into the mounting hole (C1). A metal shield shell (60) accommodates the wire introducing portion (32) and includes a lower shell (62) for covering the entire outer circumferential surface of the wire introducing portion (32). A seal ring (72) fits on an outer surface of the wire introducing portion (32) and seals between the lower shell (62) and the wire introducing portion (32). Water drainage holes (77) vertically penetrate a stepped portion (69) of the lower shell (62) above the seal ring (72).
