Abstract: A connector housing is provided capable of reliably preventing a terminal fitting from being inserted and accommodated in a vertically inverted posture into a cavity. A connector housing includes a cavity capable of accommodating a terminal fitting provided with a projection on an outer side surface of a terminal main body portion in the form of a rectangular tube. The cavity includes a main body accommodating portion into which the terminal main body portion is to be accommodated and a groove portion into which the projection is insertable and movable forward when the terminal fitting is inserted in a proper posture into the cavity. A guiding portion for angularly displacing the terminal main body portion by coming into contact with the projection when the terminal fitting is inserted in a vertically inverted posture into the cavity is provided on a side of the cavity before the main body accommodating portion.

Abstract: A connector includes a first housing (10) with a terminal accommodating portion (11) surrounded by a peripheral wall (17), a second housing (60) connectable to the first housing (10), and a detector (40) to detect a connected state of the housings (10, 60) based on whether the detector (40) moves from an initial position to a detection position in a space between the terminal accommodating portion (11) and the peripheral wall (17). An opening (22) extends circumferentially in a part of the peripheral wall (17) and exposes the detector (40). Deformation regulating portions (23, 53) are formed on the peripheral wall (17) and the detector member (40) and permit movements of the detector (40) between the initial position and the detection position and regulate deformation of the peripheral wall (17) to enlarge an opening width of the opening (22) by being fit to each other.

Abstract: A lever-type connector includes a housing (10) connectable to a mating housing, and a lever (60) mounted on the housing (10) rotatably between an initial position and a connection position. The housing (10) includes a fixing portion (21) to be fixed to a fixing surface (91) and reinforcing portions (24) integrally coupled to the fixing portion (21) and configured to reinforce the fixing portion (21). The reinforcing portions (24) additionally have a function as a stopper for regulating the rotation of the lever (60) in a direction opposite to a direction toward the connection position by contact with the lever (60) at the initial position.

Abstract: In the process of inserting a terminal fitting (90) into a cavity (20) of a housing (10), a stabilizer (95) enters a guiding groove (31) and an inserting operation of the terminal fitting (90) is guided. The front end of the guiding groove (31) defines a closed end part (32). When a retainer (60) is mounted into the housing (10), locking portions (66) are inserted into communication holes (33) and locked to the closed end parts (32) of the guiding grooves (31), thereby preventing the retainer (60) from coming out of the housing (10).

Abstract: A lever-type connector has a housing (20) and a linking wall (25) projects from the housing (20) to define a stop for a mating housing (90). A seal ring (70) is mounted adjacent to the linking wall (25) to provide sealing between the housing (20) and the mating housing (90). A lever (60) includes a coupling (61) and arm plates (62) to define a U-shape. The lever (60) is mounted from an outer side to straddle the housing (20). The linking wall (25) is arranged at a position facing the arm plates (62) from inner sides of the arm plates (62). Cam grooves (64) are provided in the arm plates (62) and function as confirmation windows through which the seal ring (70) is visible to confirm whether sealing is ensured.

Abstract: A seal (40) includes an annular portion (41) to be fit externally on a housing main body (11) and resiliently sandwiched between the housing main body (11) and a receptacle (71) when two housings (10, 70) are connected and projections (42) protruding radially out after projecting back from the annular portion (41) and configured such that protruding parts thereof resiliently contact the tip of the receptacle (71) when the two housings (10, 70) are connected. The housing (10) includes deformation guides (24) configured to deform the seal (40) such that a radially outward protruding amount of the projections (42) gradually increases by sliding on the projections (42) in the process of moving the annular portion (41) externally fit on the housing main body (11) toward a proper mounted position.

Abstract: A lever-type connector has a housing (20) and shafts (33) project from opposite side surfaces of the housing (20). Outward deformation preventing walls (35) define open inner spaces (37) on sides of the shafts (33). A U-shaped lever (60) has a coupling (61) and two arm plates (62). The arm plates (62) are mounted on the shafts (33) for rotation between an initial position and a connection position. Each arm plate (62) includes a thin portion (66) and a thick portion (68). The thin portions (66) of the arm plates (62) deform out due to interference with the shafts (33) and enter the inner spaces (37) of the outward deformation preventing walls (35) of the housing (20) at the assembled position. The thick portions (67) of the arm plates (62) enter the inner spaces (37) of the outward deformation preventing walls (35) when moving toward the connection position.

Abstract: A connector has a slider (60) with a base (61) extending along a width direction and to be inserted below a lock arm (17). Two arms (62) project from opposite widthwise ends of the base (61). A coupling (63) couples projecting end parts of the arms (62) and faces an upper surface side of the lock arm (17). A deflectable initial position holding portion (76) is provided on the base (61) and is configured to regulate a movement of the slider (60) to a connection position by resiliently locking an initial position holding receiving portion (25) of a housing main body (11) at an initial position. A connection position holding portion (64) is provided on the coupling (63) and is configured to regulate a detachment of the slider (60) by contacting a connection position holding receiving portion (23) of the lock arm (17) at the connection position.

Abstract: A connection detector (40) has two connection detection function portions (41) individually corresponding to two lock arms (30) and joined by a detecting portion (45). The connection detector (40) is held at an initial position when a male connector (M) and a housing (20) are not connected properly and can move to a detection position when the male connector (M) and the housing (20) are connected properly. The detecting portion (45) is formed with a lock (48) that restricts a movement of the connection detector (40) at the initial position toward a side opposite to the detection position to be separated from the housing by being locked to a stopper (24) of the housing (20).

Abstract: First and second stabilizers (26, 27) project on a main body (11) of a terminal fitting (10) while being spaced apart in a direction intersecting with a front-back direction. The first stabilizer (26) has a front end extending steeply in a direction substantially perpendicular to the front-back direction and the second stabilizer (33) has a front end part inclined to recede. A front end of the second stabilizer (33) is more forward than the first stabilizer (26) so that the front end of the second stabilizer contacts a facing wall surface of a connector housing (60) before the first stabilizer (26) when an insertion posture is incorrect.

Abstract: A connection detector (40) has two connection detection function portions (41) individually corresponding to two lock arms (30) and joined by a detecting portion (45). The connection detector (40) is held at an initial position when a male connector (M) and a housing (20) are not connected properly and can move to a detection position when the male connector (M) and the housing (20) are connected properly. The detecting portion (45) is formed with a lock (48) that restricts a movement of the connection detector (40) at the initial position toward a side opposite to the detection position to be separated from the housing by being locked to a stopper (24) of the housing (20).

Abstract: A lever-type connector has a housing (20) and shafts (33) project from opposite side surfaces of the housing (20). Outward deformation preventing walls (35) define open inner spaces (37) on sides of the shafts (33). A U-shaped lever (60) has a coupling (61) and two arm plates (62). The arm plates (62) are mounted on the shafts (33) for rotation between an initial position and a connection position. Each arm plate (62) includes a thin portion (66) and a thick portion (68). The thin portions (66) of the arm plates (62) deform out due to interference with the shafts (33) and enter the inner spaces (37) of the outward deformation preventing walls (35) of the housing (20) at the assembled position. The thick portions (67) of the arm plates (62) enter the inner spaces (37) of the outward deformation preventing walls (35) when moving toward the connection position.
