Abstract: A lever (24) is formed with a separating cam surface (30) and an escaping space (31) disposed in a region more distant from a rotary shaft (13) than the separating cam surface (30). The separating cam surface (30) presses cam projections (23) of a moving plate (18) in a direction away from the rotary shaft (13) to separate both housings (10, 40) in the process of rotating the lever (24) to an initial position with the both housings (10, 40) connected. The cam projections (23) are accommodated into the escaping space (31) while being separated from the separating cam surface (30) in the process of rotating the lever (24) from the initial position to a connection position with the both housings (10, 40) separated and the moving plate (18) located at a protection position.

Abstract: It is aimed to provide a connector capable of ensuring predetermined sealability. A connector is provided with a housing connectable to a mating housing, a seal to be mounted into the housing, and a moving member movable with respect to the housing. The seal has a sealing surface to be held in close contact with the mating housing. The moving member is arranged at a position facing the sealing surface of the seal before connection of the both housings.

Abstract: A split connector includes a housing (10) with an accommodating portion (12) and sub-connectors (20) are inserted into the accommodating portion (12). Terminal fittings (23) and retainers (30) are inserted into the sub-connectors (20). Guide recesses (14L, 14R) are formed on an inner surface of the accommodating portion (12) and extend along an inserting direction of the sub-connectors (20) into the accommodating portion (12). Guide projections (29L, 29R) are formed on outer surfaces of the sub-connectors (20) and fit into the guide recesses (14L, 14R) in an inserting process into the accommodating portion (12). Detecting projections (34L, 34R) on outer surfaces of the retainer (30) are configured not to fit into the guide recesses (14L, 14R) when the retainers (30) are at a partial locking position but fit into the guide recesses (14L, 14R) when the retainers (30) are at a full locking position.

An entrance preventing wall (26) extending obliquely backward in a cantilever manner from an upper wall (23) constituting the box-shaped portion (12) is formed in the box-shaped portion (12).

Abstract: A terminal fitting includes a terminal connection part and a crimping part. Paired front-side crimping pieces and a lower plate part constitute a wire barrel portion which contacts core wires exposed outside as a result of removal of coating disposed at an end portion of an electric wire and is crimped so as to surround the core wires. Paired rear-side crimping pieces and the lower plate part constitute an insulation barrel portion which contacts coating at the end portion of the electric wire and is crimped so as to surround the coating. At least one pair of the crimping pieces has a thin portion formed thinner than the lower plate part and contacting the electric wire end when the crimping pieces are crimped. The thin portion is formed at an intermediate portion of each crimping piece except for a peripheral portion.

Abstract: A terminal fitting has a base (11) for receiving a cylindrical sealing plug (70) mounted on an end of a wire (60) and crimping pieces (14F, 14R) projecting from opposite lateral edges of the base (11). The crimping pieces (14F, 14R) are crimped into connection at different positions of the outer circumferential surface of the sealing plug (70) in forward and backward directions. The base (11) is arranged Circumferentially along the lower half of the outer circumferential surface of the sealing plug (70) from its connected positions with the respective crimping pieces (14F, 14R) and includes receiving portions (16F, 16R) which have lateral edges (16E) facing the leading ends of the respective crimping pieces (14F, 14R) in circumferential direction and located at the upper half of the outer circumferential surface of the sealing plug (70).

Abstract: A connector housing (10) is formed with a mount hole (21) for a retainer (60), and the retainer (60) is inserted into the mount hole (21) to lock and retain terminal fittings (40) inserted into cavities (13). Partition walls (28) partitioning the cavities (13) adjacent in width direction in the connector housing (10) are provided with extended walls (28) projecting into the mount hole (21). The retainer (60) is provided with recesses (66) at positions corresponding to the extended walls (28). A creepage distance between the terminal fittings (40) adjacent with the partition wall (27) therebetween is made longer by the extended wall (28), whereby the short circuit of the adjacent terminal fittings (40) can be prevented.

Abstract: A female terminal fitting (10) is provided with a tubular main portion (30), into which a mating male tab (70) is inserted along an axial center A from the front. A resilient contact piece (80) extends back in the main portion (30) and has a free end slidable on an inner surface of the main portion (30). The inner surface of the main portion (30) includes a first slide surface (51) aligned for permitting displacement of the free end of the resilient contact piece (80) while maintaining a uniform distance to the axial center (A) of the main portion (30) and a second slide surface (52) for permitting displacement of the free end of the resilient contact piece (80) while increasing the distance to the axial center (A) of the main portion (30).

Abstract: A shielding shell (30) of a male housing (10M) and a shielding shell (30) of a female housing (10F) have the same shape, touching portions (35) of the shielding shells (30) are such that outer touching pieces (32) having contact points at the inner sides and inner touching pieces (31) having contact points at the outer sides are arranged in circumferential direction, and the inner touching pieces (31) of one shielding shell (30) and the outer touching pieces (32) of the other shielding shell (30) correspond to and come into contacting with each other in radial directions. Since the shielding shell (30) of the male housing (10M) and that of the female housing (10F) have the same shape, cost can be reduced.

Abstract: A frame (10) is provided with accommodating chambers (13) capable of accommodating auxiliary housings (20). A small housing (30) and a supplementary housing (40) also are provided. The housings (30, 40) are united by engaging a dovetail groove (33) and a dovetail projection (43) to form a united housing (50) that has an outer configuration common to the auxiliary housings (20). The auxiliary housing (20) and the united housing (50) can be selectively accommodated into the same accommodating chamber (13) of the frame (10). It is sufficient to prepare a single frame (10) regardless of whether the small housing (30) is used for a specific circuit. Thus, different arrangements can be dealt with inexpensively and efficiently.
