  • Patent number: 11322888
    Abstract: A lever (24) is formed with a separating cam surface (30) and an escaping space (31) disposed in a region more distant from a rotary shaft (13) than the separating cam surface (30). The separating cam surface (30) presses cam projections (23) of a moving plate (18) in a direction away from the rotary shaft (13) to separate both housings (10, 40) in the process of rotating the lever (24) to an initial position with the both housings (10, 40) connected. The cam projections (23) are accommodated into the escaping space (31) while being separated from the separating cam surface (30) in the process of rotating the lever (24) from the initial position to a connection position with the both housings (10, 40) separated and the moving plate (18) located at a protection position.

  • Patent number: 11088488
    Abstract: A moving plate (12) for protecting tips of male tabs (15) is mounted into a receptacle (18). The moving plate (12) includes a peripheral wall (36) in the form of a rectangular frame, and the peripheral wall (36) includes long sides (43) and short sides (44). Projections (50) are provided on both sides across a center in a longitudinal direction on an outer surface of each long side (43). Recesses (31) shaped to correspond to the respective projections (50) and to be fit to the projections (50) are provided at positions corresponding to the projections (50) on an inner surface of the receptacle (18). Each of the projections (50) has a one-sided dovetail shape projecting toward a central side in the longitudinal direction, but not protruding toward an end side in the longitudinal direction.

  • Patent number: 10644445
    Abstract: A lever-type connector has a lever (24) with a cam groove (28) curved to approach a center of rotation (13) of the lever (24) from an entrance (28E) to a back side. Rotation of the lever (24) from an initial position to a connection position causes cam projections (23) of a moving plate (18) to displace in the cam groove (28) and to approach the center of rotation (13) of the lever (24) while sliding in contact with a cam pin (41) of a female housing (40). The cam projections (23) displace in an escaping space (31) of the lever (24) without changing a positional relationship with respect to the center of rotation (13) of the lever (24) as the lever (24) is rotated from the initial position to the connection position in a state out of contact with the cam pin (41).

  • Patent number: 10644446
    Abstract: A female housing (40) is formed with a cam pin (41) having a projecting dimension larger than cam projections (23) of a moving plate (18), and a lever (24) is formed with a cam groove (28) for accommodating the cam projections (23) and the cam pin (41) in the process of connecting/separating both housings (10, 40). An escaping space (31) communicates with the cam groove (28) and is configured to restrict entrance of the cam pin (41) by being shallower than the cam groove (28). In the process of rotating the lever (24) from an initial position to a connection position in a state where the housings (10, 40) are separated and the moving plate (18) is at a protecting position, the cam projections (23) are accommodated into the escaping space (31) while being kept out of contact with the lever (24).

  • Patent number: 10340728
    Abstract: A temperature detector detects a temperature of a battery. A charging unit charges the battery. A power reception coil receives a first electric power transmitted in a contactless manner from a power transmission coil of a contactless charging device. A supplying unit supplies the charging unit with a second electric power on the basis of the first electric power. A setting unit sets a supply current to be supplied from the supplying unit to the charging unit. A determination unit determines whether the battery is continuously charged. The setting unit sets the supply current to a value larger than a settable minimum value regardless of the temperature of the battery when the charging unit starts charging the battery on the basis of the second electric power, and reduces the supply current as the temperature is higher when the determination unit determines that the battery is continuously charged.

  • Patent number: 10069321
    Abstract: A delayed power-on function for an electronic device is disclosed. A charging unit charges a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value and with a current larger than the pre-charge current when the voltage of the rechargeable battery is greater than the voltage threshold value. A controller can disable power-on when the voltage of the rechargeable battery is less than the voltage threshold value. A user may also be notified when power-on is disabled.
