  • Patent number: 8894444
    Abstract: A coaxial electrical connector having a shorter height and improved retention strength against mating and removal with a simple structure is provided. A connector mounting portion P1 is formed as a recess or a through hole in a printed wiring board P, and the connector is mounted such that its insulating housing 11 is inserted into this connector mounting portion P1 of the printed wiring board P, so that the height of the connector is reduced. Load applied when a counterpart electrical connector 20 is mated with or removed from the connector is stably supported by the insulating housing 11 via a connector holding portion 11c, so that components such as conductive contacts are prevented from deformation, and solder joints are prevented from peeling.

  • Patent number: 8636542
    Abstract: Coaxial connector comprising a signal contact member having a connecting terminal portion and a contacting terminal portion, a grounding contact member having an annular engaging portion for engaging with an outer contact member of a mating coaxial connector and a shell portion extending from the annular engaging portion to be connected with an outer conductor of a coaxial cable, and a housing for supporting the signal contact member and the grounding contact member. The connecting terminal portion of the signal contact member is positioned at the outside of the annular engaging portion of the grounding contact member to be connected with a core conductor of the coaxial cable and the contacting terminal portion of the signal contact member is positioned at the inside of the annular engaging portion of the grounding contact member for coming into contact with a central contact member of the mating coaxial connector.
