  • Patent number: 7134886
    Abstract: L-shaped terminal fittings (11A, 11B) have terminal connecting portions (12) at one end. The terminal connecting portions (12) are pressed into upper and lower stages of a housing (20) for connection with a mating terminal. Narrower board connecting portions (13) are at the opposite ends of the terminal fittings (11A, 11B) and have mounting portions (16) to be soldered to a PCB (40). The terminal connecting portions (12) of the upper stage align respectively with the terminal connecting portions (12) of the lower stage. However, the board connecting portions (13) in the upper and lower stages are offset laterally with respect to longitudinal axes (X) of the terminal connecting portions (12). Additionally, all of the board connecting portions (13) of the terminal fittings (11A, 11B) are arrayed in one row equally spaced from the housing (20).

  • Patent number: 7125291
    Abstract: Receiving portions (26, 27) for partial locking and full locking are formed on walls of a retainer mount hole (24) in a housing (10). The receiving portions (27) for full locking are before the receiving portions (26) for partial locking with respect to an inserting direction of a retainer (30). Resiliently deformable holding arms (35A, 35B) for partial locking and full locking are cantilevered on the retainer (30), and locking sections (41, 42) resiliently engageable with the corresponding receiving portions (26, 27) are formed at the free ends of the holding arms (35A, 35B). The holding arms (35A) for full locking extend in the inserting direction of the retainer (30) from their supported ends to their free ends, whereas the holding arms (35B) for partial locking extend in a direction opposite from the inserting direction of the retainer (30) from their supported ends to their free ends.

  • Patent number: 7118417
    Abstract: A female housing (40) has a lock arm (40) with an arm main body (43) that cantilevers back from the front of the female housing (40). A lock (46) is formed on the arm main body (43). An unlocking portion (44) is at the rear end of the arm main body (43) and extends normal to the arm main body (43). Arm portions (55) project obliquely downward from the opposite sides of the unlocking portion (44), and are coupled to protection walls (52) to sandwich the unlocking portion (44). Two restricting walls (55) project from the upper ends of the protection walls (52) at positions behind the arm portions (50) and higher than the arm portions (50) and face each other. The restricting walls (55) prevent an operator's finger from touching the arm portions (50).

  • Patent number: 7033205
    Abstract: Collision preventing projections (50) are provided on an outer surface of a female housing (20) and will contact an opening of a receptacle (11) of a male housing (10) if a main portion (21) of the female housing (20) is inserted into a receptacle (11) in an oblique posture. Thus, the collision preventing projections (50) ensure that the main portion (21) and male terminals (12) are spaced apart when the main portion (21) is pushed into the receptacle (11) in this oblique posture.

  • Patent number: 7011541
    Abstract: A female housing (20) is provided with a lock arm (30) for holding a mating male connector (M) in a connected state. The lock arm (30) is comprised of an arm (31) extending along forward and backward directions and an actuator (32) extending along a width direction. The arm (31) is resiliently deformed with a support (33) as a supporting point and has a lock (34) engageable with the male connector (M). The arm (31) is displaced in unlocking direction by pressing the actuator (32). Two couplings (35) coupled to the female housing (20) are provided at opposite sides of the actuator (32). The couplings (35) are inclined up towards a widthwise middle (32a) of the actuator (32).

  • Patent number: 7008254
    Abstract: A female housing (20) made of a synthetic resin is formed with cavities (22) for accommodating female terminal fittings (21), and locks (24) engageable with the female terminal fittings (21) to retain them are provided in the cavities (22). Each lock (24) projects from an outer surface (20a, 20b) of the female housing (20) during resilient deformation. A lock arm (40) for holding a mating male connector (M) in a connected state is mounted on the female housing (20). The lock arm (40) is made of metal and includes a press-in portion (42) that can be pressed into press-in grooves (30) of the female housing (20). The lock arm (40) is arranged to face the locks (240) and can be retracted into deformation spaces (330) for the locks (240) during the resilient deformation.

  • Publication number: 20050260883
    Abstract: Male connectors (10) are accommodated in an ECU casing C, and connect with female connectors (20) connected with ends of wires (Wa). The male and female connectors (10, 20) are locked together by engaging a lock (45) on a lock arm (40) of the female connector (20) with an engaging portion (47) of the male connector (10). The fracture strength of the engaging portion (47) of the male connector (10) exceeds the fracture strength of the lock (45) of the female connector (20). Thus, an excessive force acting to separate the locked connectors (10, 20) will fracture the lock (45) of the female connector (20) first to cancel the locked state. This avoids fracturing the engaging portion (47) of the male connector (10).

  • Patent number: 6935905
    Abstract: A connector includes a housing (130) with a cavity (131) and a lock (133) that is resiliently deformable along a deformation direction (DD). A terminal fitting (110) is insertable into and withdrawable from the cavity (131) along inserting and withdrawing directions (IWD) and is configured to be locked by the lock (133). A jig (160) can be slid linearly into a jig insertion space (148) between the terminal fitting (110) and the lock (133) for disengaging the lock (133) from the terminal fitting (110).

  • Patent number: 6835106
    Abstract: A female connector has a housing (6) in which terminal fittings can be accommodated. A retainer (12) can be engaged lightly with the housing (6) at a partial locking position. The retainer (12) also can be engaged more deeply at a full locking position where the retainer (12) locks the terminal fittings. Housing ribs (7B) project from an outer surface (25) of the housing (6), and retainer ribs (27) project from the retainer (12) and extend along the extension of the housing ribs (7B). The retainer ribs (27) project beyond the housing ribs (7B) when the retainer (12) is at the partial locking position.
