Abstract: A heating device for a vehicle is described. The heating device includes a heater core and a housing assembly. The housing assembly includes a housing configured with a protruded portion, a first terminal, and a second terminal. The first terminal is configured on the protruded portion of the housing and adapted to be connected with a first bus bar. The second terminal is configured on a first end of the housing and adapted to be connected with a second bus bar. The first bus bar and the second bus bar are connected to the heater core to provide an electrical connectivity to the heater core. The first terminal and the second terminal are laterally offset to each other, and are at least partially on opposite sides of a reference line coinciding with an edge of a printed circuit board received in the housing.
