Abstract: A method for manufacturing a forged article, capable of improving the durability of a die for forging is provided. The method, includes forging a steel material, by using a die, by spraying or applying a water-soluble polymer lubricant containing 0.01 to 0.98 mass % of a water-soluble sulfate onto a working surface of the die, the die being made of a raw material having a constituent composition of by mass %, of 0.4 to 0.7% of C, 1.0% or less of Si, 1.0% or less of Mn, 4.0 to 6.0% of Cr, 2.0 to 4.0% of (Mo+½W), 0.5 to 2.5% of (V+Nb), 0 to 1.0% of Ni, 0 to 5.0% of Co, 0.02% or less of N, and a remnant composed of Fe and impurities, and having hardness of 55 to 60 HRC, and the die including a nitrided layer or a nitrosulfidized layer on the working surface thereof.

Abstract: A rib (54) of a sub-connector (30) is inserted into a groove (22) of a housing (10) if the sub-connector (30) is accommodated inside a correct accommodation concavity (11). A projected strip (77) of a wire cover (70) then is inserted into the groove (22) with the projected strip (77) and the rib (54) being side by side. Thus the wire cover (70) is prevented from being opened. The rib (54) may be inserted into the groove (22) if the sub-connector (30) is accommodated inside an incorrect accommodation concavity (11). But when an operation of mounting the wire cover (70) on the housing (10) in the above-described state is performed, the projected strip (77) interferes with the rib (54) inserted into the groove (22) to stop the mounting the wire cover (70) on the housing (10).

Abstract: Front ends of the locking strips (59) of the holder (50) are shifted from each other in a longitudinal direction thereof. Front ends of the locking part receiving parts (37) of a sub-housing (31) are located at different positions in a longitudinal direction thereof. When the holder (50) takes a normal mounting posture relative to the sub-housing (31), all of the locking parts (60) are fitted on the locking part receiving parts (37) corresponding thereto respectively after each of the locking strips (59) performs an elastic operation. Thereby the holder (50) is held by the sub-housing (31). When the holder (50) takes an incorrect mounting posture relative to the sub-housing (31), at least one of the locking parts (60) cannot be fitted on the locking part receiving parts (37) corresponding thereto. Thereby the holder (50) is separable from the sub-housing (31).

Abstract: A connector (10) has first and second housings (20, 40). The first housing (20) has a tubular hood (21) with opposite first and second surfaces and the second housing (40) can be fit in the tubular hood (21). A terminal fitting (80) and a retainer (60) are mounted in the second housing (40). A guide (29) projects from the second inner surface of the hood (21), and a striking part (27) projects from the first inner surface of the hood (21). The second housing (40) slides along the guide (29) in a process of fitting the second housing (40) in the hood (21) and is displaced toward the striking part (27). The retainer (60) projects from the second housing (40) prior to complete insertion and will strike against the striking part (27) to prevent the second housing (40) from fitting farther into the hood (21).

Abstract: A female housing (10) includes cam pins (14). A lever (70) is mounted on a male housing (30), and arms (73) of the lever (70) are formed with bearing portions (74) and cam grooves (71) engageable with the cam pins (14). An engaging groove (78) is formed adjacent to the cam groove (71) in each arm (73), and an engaging pin (17) is provided adjacent to each cam pin (14) on the female housing (10). The engaging grooves (78) can receive the engaging pins (17) during the rotation of the lever (70) and have inclination restricting surfaces (79) for restricting the inclination of the female housing (10) by sliding in contact with the engaging pins (17) as the lever (70) is rotated if the posture of the female housing (10) being connected is inclined relative to the female housing (30).

Abstract: If resilient locking pieces (26) are displaced together with side walls (21) in disengaging directions from locking portions (13) due to an external force acting on a wire cover (20), guide projections (28R) formed on the side walls (21) try to be displaced in the same directions as projecting directions of restricting projections (29). However, as the guide projections (28R) are displaced, the restricting projections (29) and guide portions (14) are engaged in larger areas. Accordingly, even if the resilient locking pieces (26) are disengaged from the locking portions (13), the detachment of the wire cover (20) from a housing (10) can be reliably prevented by the engagement of the restricting projections (29) and the guide portions (14).

Abstract: A grommet (30) has a wire pull-out part (32) that extends at an angle to a direction in which a female housing (10) fits to a mating male housing (90). Wires pulled out from the female housing (10) are inserted into the electric wire pull-out part (32). A locking hole (35) is formed on the grommet (30) near the wire pull-out part (32) and can be fit on a locking projection (11) on the female housing (10). A grommet cover (50) has a lid (51) that can be opened and closed. The lid (51) has a convex grommet-engaging portion (52) that engages the grommet (30) between the locking hole (35) and the wire pull-out part (32) when the lid part (51) is closed thus preventing a periphery of the locking hole (35) from deforming in a direction in which the wire pull-out part (32) shakes.

Abstract: A connector (F) has a main body (10) with an outer surface. Shafts (11) project from the outer surface and a retainer (12) projects from each shaft (11). A lever (20) has bearing holes (23) with notches (26) dimensioned to receive one of the retainers (12). The notches (26) align with the retainers (12) in a connection ending position of the lever (20) so that the lever (20) can be mounted rotationally on the main body (10) or removed from the main body (10). A resilient lock (14) presses the lever (20) parallel to the axis of the shafts (11) so that the retainers (12) engage edges of the bearing holes (23) to prevent detachment of the lever (20) from the shafts (11) in other rotational orientations.

Abstract: A grommet (40) is externally attached to a connector holder (20) mountable on a panel (P) while being introduced through a mount hole (H) in the panel (P). The connector holder (20) has a flange (34) for holding the grommet (40), and includes lock arms (32) for holding the connector holder (20) on the panel (P) by engaging the front edge of the mount hole (H). The lock arms (32) are inward from the flange (34). Operating notches (35) are formed in portions of the flange (34) corresponding to the lock arms (32). Thus, portions of the lock arms (32) projecting backward from the panel (P) can be operated from outside via is the grommet (40) to displace the lock arms (32) while disengaging them from the panel (P).

Abstract: A connector has a retainer (3) which is slidable on a connector housing (2) while maintaining a given relation of position to the housing (2). In this connector, the retainer (3) is provided on a face opposed to the housing (2) with a hook like bend guide rib (21) which extends in a width direction. The guide rib (21) is provided on an outer surface of its distal end with a down slant guide face (27) adapted to engage with the guide face (23). When the retainer is attached to the housing (2) in a retracted position, the guide faces (23, 27) are spaced away from each other. When the retainer (3) is slid to an advanced position on the housing (2), the guide faces (23, 27) engage with each other, thereby bringing the retainer (3) into the advanced position while preventing the retainer (3) from floating up.
