Abstract: A rectangular tube (10) of a terminal fitting (T) includes a lid plate (16) extending substantially at a right angle from the extending end of a right side plate (15) and formed with a locking hole (20) extending over the entire width. A front plate (19F) is cantilevered from the right side plate (15) and arranged before the locking hole (20). A rear plate (19R) is cantilevered from the right side plate independently of the front plate (19F) and is behind and adjacent to the locking hole (20). A retracted portion (21) is formed over the entire width at the rear plate (19R), retracted inwardly of the rectangular tube (10) from the front plate (19F) to provide a height difference within the range of an engagement margin with a locking projection (34) and capable of facing a rear end of the locking projection (34).

The connector (10) includes a housing (20), a lock arm (40) provided displaceably relative to the outer surface of the housing (20) and adapted to hold a mating housing and the housing (20) in a connected state. Couplings (51) connect the lock arm (40) and the housing (20) and have front and rear curved surfaces (57F, 57R). Front steps (54F) extend continuously forward from the end edge (58F) of the front curved surfaces (57F) closer to the rear curved surfaces (57R). Rear steps (54R) extend continuously back from end edges of the rear curved surfaces (57R) closer to the front curved surfaces (57F). Pairs of curved portions (59F, 59R) facing forward and back are provided at opposite ends of the curved surfaces (57F, 57R) in directions crossing the curving directions.

Abstract: A connector has a female terminal (20) with stabilizers (30) that contact restricting surfaces (64) of an edge of a terminal accommodating hole (51) at a side opposite to a side where insertion paths (60) are provided, thereby preventing any further insertion of the female terminal (20) when a female terminal (20) is inserted in a posture vertically inverted from a proper posture. Posture displacing portions (65) are provided on the restricting surfaces (64) of the terminal accommodating hole (51) and engage the stabilizers (30) of the female terminal (20) inserted in the inverted posture to displace extending postures of the stabilizers (30) to increase engaging margins with the restricting surfaces (64).

Abstract: A female terminal has left and right stabilizers (30) extending from one surface of a rectangular tubular main portion (21). The stabilizers (30) are formed at predetermined distances in from opposite left and right lateral edges of the surface of the main portion (21) toward a widthwise center and assume oblique postures so that both extending ends gradually come closer to each other. The extending ends of the both stabilizers (30) are located within a circumscribed circle (X) of the main portion (21), C-surfaces (35A) are formed on corner portions of the outer lateral edges of extending end surfaces (31) of the both stabilizers (30) and R-surfaces (37A) are formed on lateral edges (36) of the C-surfaces (35A) on base end sides of the stabilizers (30).

Abstract: A grinding machine is provided with first and second grinding wheels selectively used in dependence on the steps of machining operations. The second grinding wheel is grooved so that at least one oblique groove vertically crosses a contact surface on which a grinding surface of the second grinding wheel contacts with a workpiece, and thus, is capable of releasing a dynamic pressure in coolant generated between the grinding surface and the workpiece since coolant supplied from over the contact surface flows out from both of the upper and lower sides of the contact surface through the at least one oblique groove. Since it does not occur that fluctuations in the dynamic pressure generated in coolant cause the distance between the second grinding wheel and the workpiece to be varied, the accuracy in grinding the workpiece with the second grinding wheel can be enhanced.

Abstract: A rough grinding process grinds the workpiece W supported by the supporting device by the rough grinding wheel until remaining a removed amount for finish grinding being preset, and then finish grinds the removed amount while the workpiece W is continuously supported by the supporting device. The removed amount for finish grinding is set based on at least one of thermal displacement of the multifunction grinding machine and changing amount of grinding force based on the rough grinding wheel. A profile remaining the removed amount for finish grinding is a profile not depending on a profile of the rough grinding wheel.

Abstract: A circular or non-circular workpiece is ground in a plurality of grinding steps, including a final finish grinding step. A grinding wheel is caused to effect profile generation movement in synchronism with rotation of the workpiece and in accordance with profile data derived from the target shape of the workpiece. In each grinding step, the grinding wheel is advanced in such a manner that the grinding wheel causes cut-in movement within a predetermined cut-in angle defined on the workpiece. After completion of the final finish grinding step, the grinding wheel is retracted over a predetermined back-off angle defined on the workpiece. The retraction is effected in accordance with composite data obtained through combining the profile data and back-off data. The back-off angle is greater than the cut-in angle employed during the final finish grinding step.
