Filed:

Mar 21, 2016

Appl. No.:

15/076246

Inventors:

- Chicago IL, US
Mario G. Sepulveda - Newark CA, US
Jason Larson - San Lorenzo CA, US

Assignee:

Littelfuse, Inc. - Chicago IL

International Classification:

H01R 13/66

Abstract:

A circuit includes a connector having first and second mateable portions. Each portion includes at least two terminals configured to mechanically engage at least two terminals of the other portion. The two terminals within the first and second portions are arranged so that as the first and second portions are mated, a first terminal of the first portion and a first terminal of the second portions come into contact before respective second terminals of the first and second portions. The circuit also includes a polymeric positive temperature coefficient (PPTC) device with a first terminal in electrical communication with the first terminal of the first portion and a second terminal in electrical communication with the second terminal of the first portion. A power terminal is in electrical communication with the second terminal of the first portion and is configured to be connected to a power source. A load terminal is in electrical communication with the first and second terminals of the second portion and is configured to be connected to a load.

International Classification:

H01F 27/28
H02J 5/00
H02J 7/02
H01F 38/14

Abstract:

Printed circuit includes a substrate body having a plurality of substrate layers stacked along a Z-axis. Each substrate layer is substantially planar and extends along an XY plane. The X-, Y-, and Z-axes are mutually perpendicular. The printed circuit also includes a Z-field coil that is coupled to the substrate body and has a conductive trace that is parallel to the XY plane. The printed circuit also includes an X-field coil having conductive trace segments that are coupled to the substrate body and parallel to the XY plane. The X-field coil includes conductive paths that extend substantially parallel to the Z-axis. The conductive paths interconnect the trace segments. The Z-field coil and the X-field coil are configured to generate respective vector components of a magnetic field or have a voltage induced therein by a magnetic field.

International Classification:

H01R 12/79

Abstract:

Flexible printed circuit (FPC) connector includes a flex circuit having first and second side surfaces and a thickness extending between the first and second side surfaces. The flex circuit includes a plurality of stacked substrate layers. The FPC connector also includes a conductive pathway extending through the flex circuit and a substrate protrusion coupled to the second side surface and projecting a distance away from the second side surface. The substrate protrusion is formed from at least one dielectric layer. The FPC connector also includes a contact pad that is directly coupled to at least one of the substrate protrusion or the second side surface of the flex circuit. The contact pad is electrically coupled to the conductive pathway.

- Berwyn PA, US
Jason Larson - San Lorenzo CA, US

International Classification:

H02J 5/00

Abstract:

A power circuit for wirelessly communicating power to a receiving device includes one or more switches for coupling respective ends of different coils of a group of coils together to facilitate selectively connecting the coils in a series configuration, parallel configuration, or combination thereof. The circuit includes a controller configured to control a conduction state of each of the one or more switches, and power terminals in electrical communication with the coils through which a power signal flows.

International Classification:

H04B 5/00

Abstract:

A contactless connector includes an insulative housing having a mating interface configured to be coupled to a connector interface of an electronic device. The housing can be reversibly coupled to the connector interface in a first orientation or in a second orientation oriented 180 degrees relative to the first orientation. A communication circuit board is held within the housing that includes a first connector communication chip and a second connector communication chip configured to define wireless communication channels with corresponding device communication chips of the electronic device in either orientation. A sensor senses the orientation of the housing relative to the connector interface of the electronic device to determine if the housing is in the first orientation or in the second orientation. The mode of operation of the first and second connector communication chips is controlled based on the sensed orientation of the housing.

International Classification:

B60L 11/18

US Classification:

320109

Abstract:

An electric vehicle support equipment (EVSE) system that includes a nozzle () configured to couple to an electric vehicle, the nozzle including a first microcontroller (MCU). The EVSE also includes a charging circuit interrupt device (CCID) configured to couple to a power source, the CCID including a second MCU and a cable that is coupled between the CCID and the nozzle. The CCID is configured to receive a pilot signal from the electric vehicle, the pilot signal conveying pilot information, and overlay additional information onto the pilot signal.
