Description

Connector assembly and vehicle

Technical Field

The disclosure relates to the technical field of vehicles, and in particular relates to a connector assembly and a vehicle.

Background

The FAKRA connector is an important component for signal transmission between vehicle-mounted multimedia devices and is mainly applied to the field of vehicle intelligent domain controllers. The FAKRA connector of the prior art is typically housed inside a controller, which inevitably has some play between the FAKRA connector and the housing of the controller due to tolerances during part production and assembly.

When the vehicle domain controller is subjected to functional test or has static electricity release in the running environment, static electricity easily enters the controller through an assembly gap between the FAKRA connector and the metal shell of the controller, and a central needle contacting the FAKRA connector enters a circuit board to influence radio frequency signals, so that certain potential safety hazards are easily brought when the automatic driving or auxiliary driving function of the vehicle is started.
