Abstract

A support of an electronic unit, configured to be integrated into a housing to support a first electronic unit and to allow electrical connection between the first electronic unit and a second electronic unit situated opposite, via at least one electrical connection element. The support includes: an open cavity for receiving the first electronic unit; a hollow column into which the at least one electrical connection element is inserted, the hollow column extending from the open cavity and being configured to communicate with the open cavity at a first end of the hollow column; and a channel including an end communicating with the bottom of the open cavity and another end communicating with a lateral wall of the hollow column.

First claim

The invention claimed is:

1. A support of an electronic unit, configured to be integrated into a housing to support a first electronic unit and to allow electrical connection between the first electronic unit and a second electronic unit situated opposite, via at least one electrical connection element, the support comprising:
an open cavity for receiving the first electronic unit;
a hollow column into which the at least one electrical connection element is inserted, the hollow column extending from the open cavity and being configured to communicate with the open cavity at a first end of the hollow column; and
a channel comprising an end communicating with a bottom of the open cavity and another end communicating with a lateral wall of the hollow column,
wherein the support of the electronic unit receives an insulating material that embeds the first electronic unit, and
wherein the hollow column is filled with the insulating material by way of the channel, the channel forming a filling element for the hollow column.

2. The support of an electronic unit according to claim 1 , in which the channel has a ramp shape.

3. The support of an electronic unit according to claim 1 , in which the channel has a helical general shape.

4. The support of an electronic unit according to claim 1 , the first electronic unit being connected electrically to a plurality of second electronic units, the support comprising:
a plurality of hollow columns, each hollow column extending from the open cavity and being configured to communicate with the open cavity at the first end of the hollow column, each hollow column being intended to receive the at least one electrical connection element for connecting each of the plurality of the plurality of second electronic units with the first electronic unit; and
a plurality of channels respectively of each hollow column, each channel comprising an end communicating with the bottom of the open cavity and another end communicating respectively with a lateral wall of each hollow column.

5. The support of an electronic unit according to claim 1 , in which the support of the first electronic unit has a general horseshoe shape.

6. The support of an electronic unit according to claim 1 , forming the support of an electronic control unit, integrated into an electric machine housing, to support the electronic control unit and to allow electrical connection between the electronic control unit and an electronic power unit situated opposite, via the at least one electrical connection element.

7. The support of the electronic unit according to claim 1 , wherein the electronic unit is an electronic board.

8. An electrical device for supplying an electric machine, comprising:
the at least one electrical connection element intended to electrically connect the at least two electronic units; and
the support of one from among the at least two electronic units according to claim 1 , wherein the at least two electronic units are situated opposite one another.

9. An electric machine for automotive vehicle, comprising at least one electrical device according to claim 8 .
