  • Patent number: 8951459
    Abstract: A method is provided for producing a connector so that a terminal fitting is unlikely to move. A terminal fitting (20) is set in a molding die assembly that has a first die (60) and a second die (70). Resin then is injected to mold housing (40) including the terminal fitting (20) as an insert. A potting material (49) then is injected into a recess (45) in the housing (40) to produce a male connector. The first die (60) has a tab insertion hole (62) for fixing the terminal fitting (20), and the second die (70) has a gate (72) for injecting the resin. A cavity (81) is formed by placing the second die (70) on the first die (60) so that a projection (26) on the terminal fitting 20 is sandwiched between fitting pressing portions on the dies (60, 70).

  • Patent number: 8501298
    Abstract: A resin-molded article 10 is formed by injecting molten resin into a molding die from a gate (11). Ribs (61, 62, 63 and 64) having widths larger than that of a thin molded portion (27) in the form of a thin wall are connected one after another from the position of the gate (11) to the thin molded portion (27). Spaces in the molding die for forming the ribs (61, 62, 63 and 64) define a path for the flow of the molten resin and the molten resin injected from the gate (11) flows into a space for forming the thin molded portion (27) through this path at the time of molding the resin-molded article (10). Therefore, the resin can be filled sufficiently for the thin molded portion (27) in the form of a thin wall located distant from the gate (11).

  • Patent number: 8118583
    Abstract: A connector (20) is placed in a first die (50) so that an end of a wall (41) of the connector (20) closely contacts a recess (55) of the first die (50) to define a cutoff (58). The dies then are closed to define a filling space (60C) between a surface (62) of a second die (51) and an outer surface (46) of the wall (41). The outer surface (46) of the wall (41) is inclined moderately upward. Molten resin is directed into the filling space (60C) and presses the inclined outer surface (46) of the wall (41) so that an inner surface (47) of the bottom wall (41) is pressed against the recess (55) of the first die (50) and strongly held in close contact by a component of this pressing force. Thus, molten resin cannot intrude through the cutoff (58).

  • Patent number: 7488904
    Abstract: A sensor unit (1) has a metal plate (10), a resin molded portion (20) and an oil temperature sensor (2). Busbars (4) made of a metal are arranged in the resin molded portion (20). Since the busbars (4) are insert-molded while having the exposed ends (4A) thereof tightly held by a pair of forming dies, a distance between the exposed ends (4A) and the placing surface 10A is held constant. Further, gate marks (5D) of the oil temperature sensor (2) are accommodated in recesses (10B) of the placing surface (10) and engaging grooves (9) and engaging projections (26A) are engaged. Thus, the oil temperature sensor (2) can be held in a proper posture. Additionally, the oil temperature sensor (2) can be held on the placing surface (10A) by riveting the exposed end (4A) and a terminal (8) of the oil temperature sensor (2).

  • Patent number: 7445481
    Abstract: A filling recess (25) for a sealant ā€œsā€ is formed in a bottom of a fitting recess (22) and a boundary stepped surface (30) is formed around the filling recess (25) to define an annular area between the filling recess (25) and the outer peripheral edge of the boundary stepped surface (30). A detecting stepped surface (34) is formed around the upper edge of the filling recess (25) and is slightly lower than the boundary stepped surface (30). A filled amount of the sealant ā€œsā€ is proper if the detecting stepped surface (34) cannot be seen, but the boundary stepped surface (30) can be seen. The filled amount is too little if both stepped surfaces (34, 30) can be seen, and it is excessive if neither of the stepped surfaces (34, 30) can be seen.
