Abstract: A male connector (10) is mounted to a case (C) of a device and includes a bolt (B) with a tightening portion (B1) to be engaged by a tool for screwing the bolt into a bolt hole (C2). A shield (20) includes an insertion hole (22) for receiving the bolt (B) and a bolt cap (40) covers the tightening portion (B1). A seat (21) is provided adjacent the insertion hole (22) and is sandwiched by an edge of the bolt hole (C2) and the tightening portion (B1) in the axial direction. A flange (B12) projects out from the tightening portion (B1). A mounting recess (D) is formed between the flange (B12) and the seat (21).

Abstract: A male connector (10) has a male terminal fitting (20) mounted in a male housing (10A). The male housing (10A) has tube (11) surrounding the male terminal fitting (20). The tube (11) is spaced out from a conductive part (23) of the male terminal fitting (20) by a distance so that a finger cannot be inserted between the tube (11) and the male terminal fitting (20). A fit-on part (31) of a female connector (30) can be inserted between the tube (11) and the male terminal fitting (20) so that a female terminal fitting (34) can contact the conductive part (23) of the male terminal fitting (20). An insulating coating (26) is formed on a front end of the male terminal fitting (20) by molding a resin to prevent shocks.

An inner surface of the cavity (13) has an erroneous insertion prevention part (22A) that engages the locking strip (37B) when the terminal fitting (30) is inserted into the cavity (13) in a posture erroneous in an orientation about an axis thereof, thus preventing erroneous insertion of the terminal fitting (30) into the cavity (13).

Abstract: A waterproof connector has an equipment-side housing (52) with a hood (55) and an wire-side housing (22) with tubular fit-on parts (24) and an interlocking fit-on part (25) that can fit in the hood (55). A rubber ring (33) is fit around an outer peripheral surface of the cylindrical fit-on parts (24) and the interlocking fit-on part (25) to seal a gap between an inner peripheral surface of the hood (55) and an outer peripheral surface of the tubular fit-on parts (24) and the interlocking fit-on part (25). A sealing surface (55A) is formed on the inner peripheral surface of the hood part (55) and closely contacts an entire outer periphery of the rubber ring (33). Air release grooves (66) are formed on portions of the inner peripheral surface of the hood (55) forward of the sealing surface (55A).

Abstract: A connector has first and second housings (10A, 30A) that can be fit together along a fit-on direction. A female terminal (14) is mounted in a cavity (12) of a first housing (10A). A lance (19) is formed inside the first housing (10A) and locks the female terminal (14) in the cavity (12). The lance (19) can deform elastically in the flexibility allowance space (22) to unlock the female terminal (14). A retainer projection (34) is provided in a second housing (30A) and projects along a fit-in direction of the first and second housings (10A, 30A). The retainer projection (34) penetrates into the flexibility allowance space (22) as the first and second housings (10A, 30A) are fit together to prevent the lance (19) from flexing in an unlocking direction.
