  • Patent number: 11081817
    Abstract: A connector (1) includes a housing (2) and first and second terminals (31, 32). One end of each terminal (31, 32) is inserted into the housing (2) and the other end thereof projects from the housing (2). Each terminal (31, 32) includes a base (33) projecting from the housing (2) and a connecting portion (34) that is wider than the base (33) toward both sides in a (Y) direction.

  • Patent number: 9024490
    Abstract: A central power supply member (S) for supplying power to windings of a stator of a motor has ring-shaped busbars (10) each including a power supply terminal (20) and connecting terminals (30) laminated and accommodated in a synthetic resin holder (50) while being insulated from each other. Power-supply side terminals (91) drawn out from a power supply are placed on the power supply terminals (20) of the busbars (10) and connected by tightening bolts (95). The holder (50) has terminal blocks (55) on which the power supply terminals (20) are placed and in which nuts (65) to be engaged with the bolts 95 are mounted with the rotation thereof prevented. Insertion grooves (88) as rotation preventing portions are formed in the rear surfaces of the terminal blocks (55) and receive bulges (27) formed on the lateral edges of vertical plates (22) of the power supply terminals (20).

  • Patent number: 8602821
    Abstract: A connector (10) has a capacitor (20) connected to a ground-side terminal (32) formed by press-working a metal base material in the form of a flat plate and is accommodated in a housing (50) made of synthetic resin. A connecting head (38) is provided on the ground-side terminal (32) and is thinner than the base material. The connecting head (38) is connected to a ground-side electrode (21B) provided on the capacitor (20) by soldering. A resiliently deformable neck (39) on the ground-side terminal (32) is narrower than the connecting head (38) and extends from the connecting head (38). A molded portion (53) is provided in the housing (50) to integrally cover the ground-side electrode (21B) of the capacitor (20) and the connecting head (38) of the ground-side terminal (32).

  • Patent number: 8550844
    Abstract: A waterproof (10) is provided with a capacitor (40); two busbars (35) connected via the capacitor (40). Each busbar (35) includes tabs (36), a coupling (37) connecting the tabs (36), and a connecting portion (38) connected to an electrode of the capacitor (40). A housing (11) houses the busbars (35) and the capacitor (40) and is open only in one direction. The housing (11) holds the terminal fittings inserted through an opening (12) of the housing (11) to be connected to the tabs (36) of the busbars (35). A seal (50) is press-fit into the housing (11) through the opening (12) and has through holes (51) through which the wires are closely inserted. A holder (60) having wire insertion holes (63) corresponding to the through holes (51) is mounted to cover the opening (12) of the housing (11) to retain and hold the seal (50).

  • Patent number: 8235743
    Abstract: A locking piece (51) posturing like a cantilever is disposed on a periphery of a connector (20) by extending the locking piece (51) forward from a rear side thereof along a direction in which the connector (20) is inserted into a mounting hole (12) of a bracket (10). A locking projection (55) which elastically locks a to-be-locked plate (13) formed at an upper side of the locking piece (51) by bending the bracket (10) rearward from an edge of the mounting hole (12) is formed by striking a part of the locking piece (51). When a force acts on the connector (20) in a removal direction, a tensile load acts on the locking piece (51). Therefore the locking piece (51) hardly deforms. Thereby it is possible to prevent the connector (20) from slipping off the bracket (10).

  • Patent number: 7189101
    Abstract: Solenoid valves (20) are mounted in a valve body (30) placed in a casing (C). An intermediate connector (10) is provided with valve fittings (15), and connectors (22) of the respective solenoid valves (20) are fittable into the valve fittings (15) at once as the intermediate connector (10) is assembled. The solenoid valves (20) are displaceable horizontally relative to brackets (40) on the valve body (30). During assembly, first positioning pins (16) on the intermediate connector (10) are inserted into first positioning recesses (31) in the valve body (30) and second positioning pins (25) on the connectors (22) are inserted into second positioning recesses (17) in the valve fittings (15). Thus, the connectors (22) are positioned in postures for fitting into the valve fittings (15).
