Abstract: A recess (67) is formed in a connection surface of a housing. A nut (52) is inserted into the recess (67) and fixed to the housing in a state exposed on the connection surface. A sealing material is introduced into the recess (67), and the outer peripheral surface of the nut (52) is coated with the sealing material. The recess (67) of the housing includes a first surface (71) arranged to face the outer peripheral surface of the nut (52) while forming an introduction space (74) for the sealing material between itself and the outer peripheral surface of the nut (52), a second surface (72) arranged to project radially outwardly from the opening edge of the first surface (71) and a third surface (73) arranged from the outer end of the second surface (72) to the connection surface in a direction crossing a projecting direction of the second surface (72).

Abstract: A connector includes a support (14) made of synthetic resin and constituting a first housing (10), a bolt (20) rotatably penetrating through the support (14), a seal ring (29) mounted between the supporting portion (14) and a head (22) of a bolt (20), a metal nut (36) embedded in the front surface of a second housing (30) and connecting the two housings (10, 30) by being threadably engaged with the bolt (20), and a stopper for preventing a threaded movement of the bolt (20) by bringing the metal parts into contact.

Abstract: A quick connector capable of surely confirming that a pipe body is engaged by a retainer when an elastically-deformable claw of the retainer and an elastically-deformable claw of a checker are adjacently arranged in an axial direction. Checker-axis direction elastically-deformable claws have distal-end sides formed flexibly deformable in the axial direction, maintain a state of being engaged by a second engagement portion of a retainer body by having deflective deformation regulated by a retainer diameter-expanding elastically-deformable claw in a state in which the retainer diameter-expanding elastically-deformable claw is expanded diametrically, and regulate sliding from a first position with respect to the retainer body toward a set radial direction by being engaged by the second engagement portion of the retainer body.

Abstract: Catches (37) project from a female housing (11) and end surfaces of a seal (12) define pressing surfaces (32). The pressing surfaces (32) are pressed to push the seal (12) to a mount position in the process of mounting the seal (12) into the female housing (11), and the seal (12) resiliently moves past the catching pieces (37) and engages with the catches (37) at the mount position. The pressing surfaces (32) of the seal (12) are arranged at positions overlapping the catches (37) in projecting directions of the catching pieces (37) when the seal (12) is mounted into the female housing (11).

The resin filler pipe, which is to be provided on a fuel supply port side, is composed of an alloy material which comprises a sea phase, an island phase dispersed in the sea phase and a sea-island compatibilizing layer present between the sea phase and the island phase. The sea phase comprises a higher-acid-modification-ratio high-density polyethylene resin (A), a lower-acid-modification-ratio high-density polyethylene resin (B), and an unmodified high-density polyethylene resin (C). The island phase comprises a polyamide resin (D). The proportion of the higher-acid-modification-ratio high-density polyethylene resin (A) is 2 to 19 wt % based on the total weight of the components (A) to (D).

Abstract: A horizontal connector (10A) is configured for mounting on a circuit board (90) so that a connecting direction with a mating connector is parallel to the surface of the circuit board (90). A vertical connector (10B) is configured for mounting on the circuit board (90) so that a connecting direction with a mating connector is normal to the surface of the circuit board (90). Board connecting portions (35A, 35B) of terminal fittings (30A, 30B) to be inserted into connection holes (91) and mounting holes (16A, 16B) of mounting portions (12A, 12B) to be mounted to fixing holes (92) are arranged at the same positions for both the horizontal connector (10A) and vertical connector (10B). Therefore, the circuit board (90) can be commonly used for both horizontal connector (10A) and vertical connector (10B).

Abstract: A base wall (21) of a connector housing (20) is formed with through holes (25), into which terminal fittings (60) are insertable. The inner surface of each through hole (25) includes an inclined portion (26) narrowed toward the rear side from the front surface of the base wall (21) and arranged at a position corresponding to projections (71) for guiding the terminal fitting (60), a straight portion (28) located behind the inclined portion (26), extending in an inserting direction toward the rear surface of the base wall (21) and having a press-in area for press-in portions (67), and restricting portions (27) defining steps together with the straight portion (28), extending from a taper end of the inclined portion (26) to the steps (35) and tightly holding rear parts of the projections (71) while preventing loose movements.

Abstract: Locking projections (31) formed on resiliently deformable resilient arms (30) hold a lever (20) at an initial position by engaging locking recesses (18). Resilient escaping portions (19), on which the locking projections (31) slide in the process of rotating the lever (20) between an assembled position and the initial position, are resiliently deformable in directions away from the locking projections (31). Upon rotating the lever (20) from the assembled position to the initial position after the lever (20) is assembled with a first housing (10), both the resilient arms (30) and the resilient escaping portions (19) are resiliently deformed. Thus, as compared with the case where only the resilient arms (30) are resiliently deformed, degrees of resilient deformation of the resilient arms (30) are reduced, wherefore deformations of the locking projections (31) to be crushed can be suppressed.

Abstract: A bending machine having: a punch and a die for bending a sheet-shaped work; pressurizing means which pressurizes the work in a space between the punch and the die by vertically moving a ram; inputting means (23) which inputs die information on the punch and the die, material information on the work and bending information; a database (25) which stores data on a pressure per unit length required for bending the work; calculating means (29) which calculates a pressure necessary for the pressurizing means based on various information inputted from the inputting means (23) and on the data on the pressure stored in the database (25); and controlling means (31) which controls the pressurizing means based on a result of calculation by the calculating means (29).

Abstract: A lever (60) of a connector can be rotated towards a connection side, and a moving plate (80) is pressed by cam pins (35) of the female connector housing (30) to reach an advanced position. As the lever (60) is rotated toward a separation side, first and second engaging portions (88), (89) are directly or indirectly engaged with separation cam surfaces (64D) of the cam grooves (64) to move the moving plate (80) to a retracted position. The moving plate (80) is not engaged with connection cam surfaces (64C) of the cam grooves (64), and the first and second engaging portions (88, 89) are provided at the outer edges of the openings of fitting recesses (85) of the moving plate (80) deviated from sides corresponding to the connection cam surfaces (64C) of the cam grooves (64).

The inner surface of each through hole (25) includes an inclined portion (26) narrowed toward the rear side from the front surface of the base wall (21) and arranged at a position corresponding to projections (71) for guiding the terminal fitting (60), a straight portion (28) located behind the inclined portion (26), extending in an inserting direction toward the rear surface of the base wall (21) and having a press-in area for press-in portions (67), and restricting portions (27) defining steps together with the straight portion (28), extending from a taper end of the inclined portion (26) to the steps (35) and tightly holding rear parts of the projections (71) while preventing loose movements thereof.

Abstract: A moving plate (40) is formed such that a wall (42) projects forward from a plate-like main body (41). Since the wall (42) surrounds only tabs (31C) located near the center of a receptacle (12) and crosses the inside of the receptacle (12) instead of extending along the inner periphery of the receptacle (12). Accordingly, even if an attempt is made to insert a female connector (50) in an oblique posture into the receptacle (12), the female connector (50) cannot be inserted deeply into the receptacle (12) due to interference with the wall (42), and the damage of the tabs (31A, 31B) and (31C) by the female connector (50) can be prevented.
