Connection terminal, circuit board assembly and vehicle

The utility model discloses a connecting terminal, a circuit board assembly and a vehicle. The connecting terminal comprises a terminal main body and a pin, the pin is connected with the terminal main body, the pin and the terminal main body are arranged along the length direction of the connecting terminal, the pin comprises a barb structure, the barb structure is distributed along the width direction of the connecting terminal, the barb structure comprises an elastic connecting part and a guide abutting part, and the elastic connecting part is configured to be connected with the guide abutting part and the pin. Thus, in the process that the pins are installed on the PCB, the PCB can abut against the guiding abutting parts to compress the elastic connecting parts to overcome the elasticity of the elastic connecting parts to retract, the pins can stretch into the conductive holes of the PCB, the elastic connecting parts recover after the pins stretch out of the other side so that the guiding abutting parts can expand, and fixing of the connecting terminals and the PCB is achieved.
