Abstract: A magnetic alignment assembly can be incorporated into an electronic device to facilitate alignment with another device. The magnetic alignment assembly can include a main magnet (e.g., a square or rectangular magnet) having a magnetic dipole in an axial direction and a ring magnet coaxial with the main magnet. The ring magnet can be smaller than the main magnet. The ring magnet can be positioned between the main magnet and an interface surface.

Abstract: A transmitter coil module for inclusion in an accessory device can include a transmitter coil capable of operating at either of two different operating frequencies. The low frequency can be in a range from about 300 kHz to about 400 kHz, and the high frequency can be in a range from about 1 MHz to about 2 MHz. To provide efficient charging at both frequencies, the transmitter coil can be formed from a compound, or multi-stranded, wire. A control module can also be provided that is external to the transmitter coil module The control module can include, for example, a printed circuit board having control circuitry to generate alternating current in the transmitter coil at either the high frequency or the low frequency.

Abstract: In a wireless charging system, a transmitter coil of a wireless charger device and a receiver coil of a portable electronic device can operate at either of two different operating frequencies. The low frequency can be in a range from about 300 kHz to about 400 kHz, and the high frequency can be in a range from about 1 MHz to about 2 MHz. To provide efficient charging at both frequencies, the transmitter and receiver coils can be formed from a compound, or multi-stranded, wire.

Abstract: Board-to-board connectors are disclosed. The board to board connectors include a plurality of external connection structures, and a plurality of receptacle contacts. Each receptacle contact may be coupled to a corresponding external connection structure. Each receptacle contact may include an opening for receiving a plug contact for a corresponding plug side board-to-board connector, and an engaging feature where at least a portion of the engaging feature extends into a portion of the opening. The opening may have a receptacle alignment feature designed to correspond with a plug alignment feature on the plug side board-to-board connector.

Abstract: An electrical connector housing has a housing body and a U-shaped lever that is connected to the housing body in a manner that the U-shaped lever can both pivot and slide relative to the housing body. The U-shaped lever engages a mounting structure so that the U-shaped lever pivots from a pre-engaged position to an engaged, extended position in order to draw a female electrical terminal into secure connection with a male electrical terminal and, simultaneously therewith, the housing body is drawn into sealing contact with the mounting structure. From the engaged, extended position, the U-shaped lever slidably moves to an engaged, retracted position relative to the housing body. The electrical connector housing and the mounting structure constitute an electrical connector assembly.

Abstract: A female terminal assembly includes a core terminal part and a generally U-shaped clip part. The core terminal part is fabricated from an electrically-conductive material and includes a generally U-shaped channel member. The generally-U-shaped channel member defines a generally U-shaped channel extending therethough and an opening into the generally U-shaped channel by a pair of side members interconnected together by a base member. The generally U-shaped clip part is fabricated from a stiff yet resilient material and includes a generally U-shaped clip part channel member defining a generally U-shaped clip part channel. The generally U-shaped clip part is sized to substantially cover the generally U-shaped channel member and is operative to apply opposing compression forces to generally the pair of side members of the U-shaped channel member urging the pair of side members towards each other and into the generally U-shaped channel.

Abstract: An electrical connector includes a shield cover forming a shield cover cavity that receives a grounding assembly and a terminal mounting block. A conduit is integrally connected to the shield cover and receives at least one cable assembly therethrough for connection to the terminal mounting block. The grounding assembly disposed between the conduit and terminal mounting block clamps an exposed wire shielding portion of the at least one cable assembly for electrically grounding the same upon fastening the electrical connector to an electrically-conductive support surface. An O-ring-like cable seal seals the at least one cable assembly in the conduit. An O-ring-like shield cover seal extends externally of and circumferentially about the shield cover to seal the electrical connector when the electrical connector is received in a barrier wall recess formed by a barrier wall structure. The electrical connector and the barrier wall structure form an electrical connector assembly.
