Abstract

The invention relates to a casing element of a first equipment, said casing element being configured to house at least one electrical conductor configured to receive an electric current, said casing element being notable in that it comprises a pair of slots provided in a wall of the casing element, the pair of slots comprising a slot on either side of a reception area configured to house said electrical conductor, and said pair of slots being provided to allow the insertion of a part with a U-shaped section, comprising a base and two arms parallel to one another and orthogonal to the base, said arms being configured to be inserted in said slots on either side of said reception area, so that the part is able to guide a magnetic flux generated by an electric current circulating in said electrical conductor.

First claim

The invention claimed is:

1. An electric equipment comprising a casing element,
said casing element being configured to house at least one electrical conductor configured to receive an electric current,
said casing element comprising a pair of slots provided in a wall of the casing element, the pair of slots comprising a slot on either side of a reception area configured to house said electrical conductor, and said pair of slots being provided to allow the insertion of a part with a U-shaped section comprising a base and two arms parallel to one another and orthogonal to the base, said arms being configured to be inserted in said slots on either side of said reception area, so that the U-shaped part is able to guide a magnetic flux generated by an electric current circulating in said electrical conductor,
the electric equipment further comprising:
at least one U-shaped part made of a magnetic material, with a base and two arms parallel to one another and orthogonal to the base, said arms being inserted in said slots on either side of the reception area, said U-shaped part being configured to guide a magnetic flux generated by a current circulating in the electrical conductor housed in the reception area,
an electrical conductor mounted in the reception area, wherein the electrical conductor locks the U-shaped part,
wherein the wall forms an outer wall of the electric equipment and the electrical conductor comprises an end that forms an external electric terminal of the electric equipment and another end connected to an electric component included in said casing element, said U-shaped part being configured to guide a magnetic field produced by a current circulating in said electric conductor to perform a measurement of said current.

2. The electric equipment according to claim 1 , comprising a U-shaped opening provided in the wall between the slots of the pair of slots so as to form a tab, said tab comprising a protrusion and a degree of flexibility adapted to ensure a fixation clip function to hold the base of the U-shaped part inserted in the pair of slots.

3. The electric equipment according to claim 2 , comprising the casing element according to claim 2 , wherein the flexibility of the tab is configured to allow the release of the U-shaped part by pressure applied on said tab in a direction opposite to the base of the U-shaped part.

4. The electric equipment according to claim 3 , wherein the electrical conductor locks the U-shaped part by preventing the movement of the tab in a direction opposite to the base of the U-shaped part that is likely to cause the release of said U-shaped part.

5. The electric equipment according to claim 4 , wherein a portion of the electrical conductor provides the locking function of the U-shaped part, said portion corresponding to a surface of said electrical conductor parallel to the wall and coming to bear against the tab, preventing all movement of the tab in a direction orthogonal to said wall and opposite to the base of said U-shaped part.

6. The electric equipment according to claim 1 , comprising a sensor, in particular a Hall effect sensor, located between the arms of the U-shaped part so as to measure a current circulating in the electrical conductor from a magnetic field guided by the U shaped part.

7. The electric equipment according to claim 1 , comprising a printed circuit board mounted in said casing element, said sensor being mounted on the printed circuit board, and said printed circuit board comprising slots in which the arms of the U-shaped part are inserted.

8. The electric equipment according to claim 6 , wherein the printed circuit board is perpendicular to the wall, and the arms of the U-shaped part are introduced into the slots following a direction that is parallel to the plane of said printed circuit board.
