Abstract

A current switch arranged between a first power line segment and a second power line segment, including: a first switch element, including a main contact and a secondary contact rigidly connected to the main contact, mounted so as to be mobile on the first power line segment so as to follow a separating travel between a closed position and an open position and a second switch element mounted so as to be freely mobile on the second power line segment and forced towards a rest position by elastic loading.

First claim

The invention claimed is:

1. A current switch arranged between a first power line segment and a second power line segment, comprising:
a first switch element comprising a main contact and a secondary contact rigidly connected to the main contact, mounted so as to be mobile on the first power line segment so as to follow a separating travel between a closed position and an open position, the main contact being arranged so as to:
be in electrical contact with the second power line segment when said first switch element is between said closed position and an intermediate opening state between said closed position and said open position,

no longer be in electrical contact with the second power line segment when said first switch element is between said intermediate opening state and said open position; and
a second switch element mounted so as to be mobile on the second power line segment and forced towards a rest position by elastic loading;
wherein the secondary contact of the first switch element is designed to:
cooperate with the second switch element so as to move the second switch element against said elastic loading in a first portion of said separating travel from the closed position to a release state between said intermediate opening state and said open position,
not interfere with the second switch element in a second portion of said separating travel between said release state and the open position, so that the second switch element is then brought back to the rest position by said elastic loading;
and wherein the second switch element and the secondary contact of the first switch element are arranged between two panels made of insulating material.

2. The switch according to claim 1 , wherein the second switch element is mounted so as to pivot on the second segment of the line, about a first pivoting axis.

3. The switch according to claim 1 , wherein the first switch element is mounted so as to pivot on the first power line segment, about a second pivoting axis.

4. The switch according to claim 2 , wherein the first switch element is mounted so as to pivot on the first power line segment, about a second pivoting axis, and wherein the first pivoting axis is parallel to the second pivoting axis.

5. The switch according to claim 4 , wherein the second switch element comprises a blade extending along a general plane that is substantially perpendicular to the first pivoting axis and a pin protruding from the blade parallel to the first pivoting axis and designed to cooperate with the secondary contact of the first switch element.

6. The switch according to claim 5 , wherein the secondary contact of the first switch element extends along a general plane that is substantially perpendicular to the first pivoting axis, the secondary contact having a first cam edge designed to cooperate with said pin through cam effect during said separating travel.

7. The switch according to claim 6 , wherein the blade of the second switch element extends between a first end close to the first pivoting axis and a second, free end, said pin being arranged close to said second end of the blade, and wherein the secondary contact of the first switch element extends between a first end close to the second pivoting axis and a second, free end, said cam edge being arranged close to said second end of the secondary contact.

8. The switch according to claim 7 , wherein the first switch element is also designed to move from said open position to the closed position along a closing travel,
and wherein the secondary contact has a second cam edge, designed to cooperate with said pin through cam effect during said closing travel, so as to temporarily move the second switch element away from the rest position during the passage of said secondary contact.

9. The switch according to claim 8 , wherein the second cam edge and/or a segment of the pin intended to come into contact with the second cam edge is electrically insulating.

10. The switch according to claim 7 , wherein the two electrically insulating panels extend perpendicular to the first pivoting axis, the two electrically insulating panels covering at least the second end of the first blade and the second end of the secondary contact when the first switch element is in the release state.

11. The switch according to claim 1 , wherein the first switch element is controlled by an actuator.

12. The switch according to claim 1 , wherein one from among the first power line segment and the second power line segment is connected to a voltage source, and the other from among the first power line segment and the second power line segment extends to a point of consumption.
