Abstract: A screwable vehicle antenna has a threaded part and a head part, which adjoins an end region of the threaded part. The threaded part and the head part both are made of electrically non-conductive material. At least one antenna radiator is arranged at least within part of the head part. A metal disk made of electrically conductive material is arranged on the head part and is used as a reflector or a ground plane. An HF electrical connector is provided, which is arranged on and fastened to a region of the head part remote from the threaded part, and the antenna radiator can be electrically connected to a plug of the HF electrical connector.

Abstract: A telematics device includes a housing, and first and second circuit boards. An electronic control unit of the telematics device is arranged on the first circuit board. At least one antenna of the telematics device is arranged on the second circuit board. The first circuit board and the second circuit board are arranged together in the housing. The first circuit board and the second circuit board are coupled by means of at least one electrical connecting element.

Abstract: An electrical connector assembly has a male and female connector. The male connector has electrical contacts in a housing for conducting AC or DC current. The female connector also includes a housing with electrical contacts to electrically couple with the male electrical contacts. The electrical contacts are coupled between a power source and a rechargeable power user, such as batteries in an electric vehicle. A mechanism to terminate power of the rechargeable power user is coupled with the system to prohibit use of the rechargeable power user during charging.

Abstract: An electrical connector assembly has a male connector and a female connector. The male connector has electrical contacts for conducting AC or DC current. The female connector includes electrical contacts for coupling with the male electrical contacts for conducting the AC or DC current. A mechanism to eliminate current arcing during disconnection of the male and female connectors is coupled with at least one of the male or female connectors.

Abstract: An electrical connector assembly has a male and female connector. The male connector has a housing with electrical contacts to conduct AC or DC current. The female connector also includes a housing to couple with the male housing. The female housing includes electrical contacts to electrically couple with the male electrical contacts. A latch mechanism is associated with the male or female connector housing to releasably couple the male and female connectors together. A lock mechanism is coupled with the latch mechanism to prohibit unauthorized disconnection of the male and female connectors in a coupled position.
