Patent number: 9186973Abstract: Provided is a connector component that allows easily performing coupling of connectors with each other. In a connector component (a vehicle-side electrical connector) according to an embodiment of the present invention, a vehicle-side connector is mounted on a base bracket via mounting members formed of rubber, elastic deformation of the mounting members permits a relative positional displacement of the base bracket and the vehicle-side connector in a compressing direction (Z-direction) as well as a relative positional displacement in a sliding direction (a direction in an X-Y plane). Therefore, even when there is a positional displacement and/or inclination between the vehicle-side electrical connector and a battery-side electrical connector and a relative positional displacement in the sliding direction has occurred, self-correction is performed by elastic deformation of the mounting members.Type: GrantFiled: March 13, 2012Date of Patent: November 17, 2015Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Mamoru Hozumi, Yoshio Ojima, Takahiro Fukagawa, Takashi Murase
