Electric heating device with electrode housing station

An air-conditioning unit comprising:

• a heating device comprising:
• a heating body supplied with current via a distribution unit to heat an airflow passing through said heating body, the heating body comprising an alignment of tubes containing heating elements flowed through by said current and electrodes located on either side of the heating elements for their supply of electric current,
• said distribution unit comprising a docking station for the electrodes, said docking station having a plurality of receptacles accommodating the electrodes and in which there are means for mechanically and electrically connecting the electrodes to the distribution unit,
• wherein said means for mechanically and electrically connecting the electrodes to the distribution unit consists of switches that are positioned in the receptacles and fixed to an electronic current supply board belonging to the distribution unit;
• the docking station further comprising:
• a lower face facing the electronic current supply board, and
• an upper face facing the tubes;
• and
• wherein each switch has a first electrical connection face for connection to the electronic board, provided with at least one pin able to be soldered to the board, and a second electrical connection face for connection to the electrode, provided with a female coupling into which a male coupling of the electrode is inserted.

A method for mechanically and electrically connecting electrodes of a heating device comprising:

• a heating body supplied with current via a distribution unit to heat an airflow passing through said heating body, the heating body comprising an alignment of tubes containing heating elements flowed through by said current and electrodes located on either side of the heating elements for their supply of electric current,
• said distribution unit comprising a docking station for the electrodes, said docking station having a plurality of receptacles accommodating the electrodes and in which there are means for mechanically and electrically connecting the electrodes to the distribution unit,
• wherein said means for mechanically and electrically connecting the electrodes to the distribution unit consists of switches that are positioned in the receptacles and fixed to an electronic current supply board belonging to the distribution unit;
• and
• the docking station further comprising:
• a lower face facing the electronic current supply board, and
• an upper face facing the tubes,
• wherein each switch has a first electrical connection face for connection to the electronic board, provided with at least one pin able to be soldered to the board, and a second electrical connection face for connection to the electrode, provided with a female coupling into which a male coupling of the electrode is inserted;
• the method comprising:
• positioning the docking station so as to bear on an electronic board;
• inserting the switches into successive orifices provided for this purpose in the docking station, and then into the electronic board until they are held in position;
• soldering the switches to the electronic board;
• and
• simultaneously threading all of the electrodes of the heating body into the corresponding switches in a single translational movement of the heating body with respect to the distribution unit.
