Abstract:
An electrical assembly (200) configured to be fixed in a housing of an electrical connector includes an electrical package (204) disposed on a substrate (202) and electrically connected to the substrate. The electrical assembly also includes a conductor (211) terminated to the substrate at a spaced apart location from the electrical package to provide at least one of power or control signals to the substrate. A terminating segment (218) of the conductor is thermally coupled to the electrical package to receive heat generated at the electrical package and dissipate the heat through the conductor away from the electrical package.
Abstract:
An input device may include: (a) a connector that recognizes a connection of an external device; (b) a switch located at an upper end portion of the connector and that connects an electrical signal when a physical input of a threshold pressure or more is pressed; (c) a substrate connected to a connection terminal of the switch and mounted at a surface in which the switch is not located; and/or (d) a key base that presses the switch.
Abstract:
An electrical connector mountable on a printed circuit board. In one embodiment, the electrical connector comprises an insulative housing comprising one or more electronic components, a plurality of electrical conductors in signal communication with the electronic components and adapted to interface with a plug and a plurality of terminals in signal communication with the one or more electronic components. In one aspect, the plurality of terminals are adapted to interface with one or more externally mounted electronic components on the printed circuit board thereby filtering signals passing between the electrical conductors and the printed circuit board, with the externally mounted electronic components mounted within the footprint of the electrical connector. Methods of manufacture for the aforementioned electrical connector and business methods are also disclosed.

Abstract:
The invention relates to an electric charger for an accumulator or a battery or the like, which is adapted for rapid charging during an on-period and comprises for this purpose control means for starting and ending the on-period. The charger is provided with a circuit for converting a supply voltage to a charging current for the battery, and further with a heat-absorbing member in heat-conducting coupling with at least an electrical component of the circuit to be protected against overheating. The control means are adapted such that the on-period cannot be restarted during an off-period following the on-period. The electric charger can hereby comprise a heat-absorbing member with a relatively low heat loss, this saving space and cost.
Abstract:
At least one electronic element (12) is ultrasonically welded to a printed circuit board (10) to create the electronic circuit. Proper alignment between terminals of a conductive circuit pattern (14) on the circuit board and terminal units (20) on the connecting surface of the electronic element is ensured by a variety of techniques: (i) small protuberances (22) on the terminal units, (ii) raised section (26) on the bottom surface of the terminal units placed to engage indented portions of the board, and (iii) corresponding posts (36) (on the electronic elements) and holes (41) (formed on the circuit board). The ultrasonic welding of the element to the printed circuit board is typically conducted at a frequency range between 25-30 megahertz which produces a vibration which grinds the terminal units of the electronic element to the terminals of the circuit pattern while also welding the element and circuit board together. Electronic circuits formed in accordance with the inventive concept disclosed herein can be comprised of stacked or interlocking combinations of weldable electronic elements. Such structures can improve rigidity and vary spacial relationships of electronic circuits.
Abstract:
A modular connector (10) housing of relatively short length and having a coupling feature, such as a tab (14) at one end and a recess (12) atthe other end, is connected with other similar connector housings. A filler material (22) having a melting point lower than that of the particular soldering method chosen is then inserted into the portion where two housings are joined thereby forming a relatively rigid long connector housing assemblage (11). A hot-melt adhesive preform (28) is then placed on the bottom of the connector housing (10) with the entire connector housing assembly aligned with and attached to a printed circuit board (24). The hot-melt adhesive (28) bonds the connector housing (10) to the substrate (24) while the filler material (22) melts away from the filler openings (16), allowing the short incremental housing lengths to move relatively free with respect to each other.
