Abstract

The invention relates to an electric-type heating device 1, particularly intended to heat an air flow passing through a motor vehicle ventilation, heating and/or air-conditioning system, comprising:

• • a heating unit 2 consisting of a frame 4 wherein at least one heating element 5 is fitted,
  • a connector 3 intended to connect the heating element 5 to an electrical power supply from the vehicle, characterized in that the connector 3 comprises a first interface 30 intended to be connected to the heating element and a second interface 17 intended to be connected to the electrical power supply from the vehicle. Application to electric radiators for a motor vehicle.

Claims

1. Electric-type heating device (1), particularly intended to heat an air flow passing through a motor vehicle ventilation, heating and/or air-conditioning system, comprising:

a heating unit (2) consisting of a frame (4) wherein at least one heating element (5) is fitted,

a connector (3) intended to connect the heating element (5) to an electrical power supply from the vehicle, characterized in that the connector (3) comprises a first interface (30) intended to be connected to the heating element and a second interface (17) intended to be connected to the electrical power supply from the vehicle.

2. Heating device (1) according to claim 1, characterized in that the connector (3) comprises at least two electrical wires (29a-29e) connected on one side to the heating element (5) and on the other to the electrical power supply.

3. Heating device (1) according to any of claims 1 or 2, characterized in that the heating element (5) consists of two electrodes (21) between which two heat sinks (27) are fitted, the two heat sinks (27) encompassing at least one PTC-effect stone (28), said stone and the heat sinks being connected by bonding.

4. Heating device (1) according to claim 3, characterized in that at least one of the electrical wires (29a-29e) is connected in a non-removable manner to at least one of the electrodes (21) of the heating element (5).

5. Heating device (1) according to any of claims 1 to 4, characterized in that the second interface (17) cooperates in a non-removable manner with a source connector (42) electrically connected to the vehicle electrical power supply via a wiring harness.

6. Heating device according to any of claims 1 to 5, characterized in that the first interface (30) comprises at least one retention means (33, 34, 35, 36) to secure the connector (3) on the frame (4).

7. Heating device (1) according to any of claims 1 to 6, wherein the frame (4) comprises a housing (15), which receives in its internal volume the first interface (30), said first interface (30) and the heating unit (2) are standardized while the second interface (17) is adaptable to the shape of the source connector (42).

8. Method to assemble a heating device (1), said device comprising a heating unit (2) consisting of a frame (4) wherein at least one heating element (5) and one connector (3) intended to connect the heating element (5) to an electrical power supply from a vehicle are fitted, said method consisting of:

attaching the connector (3) to the frame (4) using retention means (33, 34, 35, 36),

connecting at least one electrical wire (29a-29e) of said connector (3) to the heating element (5).
