Abstract:
An inductivecharging system includes an electronic device (100) having an enclosure (102), and an internal inductive charging assembly (120) positioned within the enclosure. The internal inductive charging assembly includes a receive inductive coil (122) positioned within the enclosure. The system also includes a charger (300) in electrical communication with the internal inductive charging assembly of the electronic device. The charger includes a transmit inductive coil (304) aligned with the receive inductive coil. The transmit inductive coil is configured to be in electrical communication with the receive inductive coil. Additionally, the system includes an inductive coupling assembly (400) positioned between the electronic device and the charger. The inductive coupling assembly includes a field-directing component (404a) configured to be in electrical communication with the transmit inductive coil, and/or the receive inductive coil of the internal inductive charging assembly of the electronic device.
Abstract:
A method for connecting or terminating wires to a printed circuit is disclosed. The method includes applying layers, such as a first layer and a second layer, to the printed circuit. The first layer is applied over several active components on the printed circuit, and provides a sealant against ingress of contaminants in the active components. The second layer is a rigid layer applied over the first layer. When the printed circuit is placed in a fixture, a metallic element, such as a thermode or hot bar, presses against the wires to hold the wires against several terminals on the printed circuit. The metallic element is heated to melt solder between the wires and the terminals. The second layer is configured to resist compressive forces from the metallic element and the fixture, such that the printed circuit and the active components are not damaged during the connection process.
Abstract:
A dual orientation plug connector having a tab portion with first and second opposing exterior surfaces that are substantially identical, parallel and opposite each other. Each exterior surface may have a plurality of electrical contacts. A substantially u-shaped metallic band surrounds a portion of the periphery of the plug connector. A contact assembly having an upper contact carrier, intermediate conductive plate and lower contact carrier may be disposed within the tab portion of the plug connector. A circuit assembly may be disposed within a body portion of the plug connector and electrically coupled to the plurality of electrical contacts.
Abstract:
A plug connector module that includes a metal frame having a base portion, an insertion end and a cavity that extends from the base portion into the insertion end. The insertion end is configured to be inserted into a cavity of a corresponding receptacle connector. A substrate extends through the base portion of the frame and into the insertion end and has a plurality of contact bonding pads at one end positioned within the frame, a plurality of conductor bonding pads at the opposing end and at least one ground pad contact between the contact bonding pads and conductor bonding pads. A first plurality of external contacts is positioned in a first opening and bonded to some of the plurality of contact bonding pads on the substrate and a second plurality of contacts positioned within a second opening and bonded to some of the contact bonding pads on the substrate.
Abstract:
A high-speed electrical connector (100) employs a plurality of electrical contacts (120(1)..120(8)) held together by a dielectric frame (205). The contacts (120(1)..120(8)) are soldered a substrate (215) within the connector (100). A gasket (218) is compressed between the dielectric frame (205) and the substrate (215)and configured to block the flow of an overmold material between the dielectric frame (205) and the substrate (215) such that voids (250) are formed between the contacts (120(1)..120(8)). The dielectric frame (205) and the overmold (230) may be made from materials containing silica aerogel. The voids (250) and the aerogel materials result in reduced parasitic capacitance between the contacts (120(1)..120(8)) enabling higher data transfer speeds.
Abstract:
Embodiments can provide reversible or dual orientation USB plug connectors for mating with standard USB receptacle connectors, e.g., a standard Type A USB receptacle connector. Accordingly, the present invention may be compatible with any current or future electronic device that includes a standard USB receptacle connector. USB plug connectors according to the present invention can have a 180 degree symmetrical, double orientation design, which enables the plug connector to be inserted into a corresponding receptacle connector in either of two intuitive orientations. Some embodiments of the present invention may be used with or require a non-standard USB receptacle connector. Thus, embodiments of the present invention may reduce the potential for USB connector damage and user frustration during the incorrect insertion of a USB plug connector into a corresponding USB receptacle connector of an electronic device.
Abstract:
This application relates to magnetically actuated electrical connectors. The electrical connectors includes movable magnetic elements that move in response to an externally applied magnetic field. In some embodiments, the electrical connectors includes recessed contacts that move from a recessed position to an engaged position in response to an externally applied magnetic field associated with an electronic device to which the connector is designed to be coupled. In some embodiments, the external magnetic field has a particular polarity pattern configured to draw contacts associated with a matching polarity pattern out of the recessed position.
