Abstract

This electric switching device ( 2 ) comprises a first module ( 4 ), including a first support ( 42 ) on which a circuit breaker ( 44 ) is mounted, and at least one second module ( 6 ), including a second support ( 62 ) on which an electric component ( 64 ) is mounted that is able to be associated with the circuit breaker. In particular in order to facilitate the maintenance of this switching device, the latter includes guiding means ( 81 and 82 ) that are able to guide the first and second supports relative to one another between a disassembled configuration, in which at least one of the first and second modules is disengageable from the guiding means independently of the other, and an assembled configuration, in which the circuit breaker and the electric component are in a relative connection position and are able to be electrically connected to or disconnected from one another.

First claim

The invention claimed is:

1. An electric switching device, embedded in a railway vehicle, comprising:
a first module including a first support on which a circuit breaker is mounted,
at least one second module including a second support, which is separate from the first support, and an electric component being mounted on said second support and being configured to be associated with the circuit breaker, and
a guide, comprising complementary shapes, configured to guide the first and second supports relative to one another between a disassembled configuration, in which at least either one of the first module and the at least one second module is disengageable from the guide independently of each other, and an assembled configuration, in which the circuit breaker and the electric component of said at least one second module are connectable to one another,
wherein said at least one second module includes a controller, which is configured to control the electric component mounted on the second support of the at least one second module,
wherein in the assembled configuration, the circuit breaker and the electric component are in a relative connection position and are-electrically connectable and disconnectable to one another by action of the controller.

2. The device according to claim 1 , wherein the guide is configured to guide in translation, along an axis, the first and second supports between the assembled configuration of the first and second supports and the disassembled configuration of the first and second supports.

3. The device according to claim 2 , wherein the guide is arranged in the first and second supports.

4. The device according to claim 1 , wherein the first and second supports include a mechanical assembly that is configured to reversibly assemble the first and second supports to one another in the assembled configuration.

5. The device according to claim 4 , wherein the assembly comprises a first part borne by the first support and a second part borne by the second support, the first and second parts cooperating by shape complementarity when the first and second supports are in the assembled configuration.

6. The device according to claim 5 , wherein one of the first and second parts of the assembly is a male element, wherein another of the first and second parts of the assembly is a female element, and wherein the male element penetrates the female element when the first and second supports go from the disassembled configuration to the assembled configuration.

7. The device according to claim 1 , wherein the device includes a fastener configured to fasten the first and second supports reversibly to the guide when the first and second supports are in the assembled configuration.

8. The device according to claim 1 , wherein the first support is a plate having a first face on which the circuit breaker is mounted and a second face, which is opposite the first face of the plate of the first support and on which a circuit controller is mounted to control the circuit breaker, wherein the second support is a plate having a first face on which the electric component is mounted and a second face, which is opposite the first face of the plate of the second support and on which the controller is mounted to control the electric component, and wherein the first face of the plate of the first support and the first face of the plate of the second support face a same side when the first and second supports are in the assembled configuration.

9. The device according to claim 8 , wherein the first face of the plate of the first support and the first face of the plate of the second support are flush when the first and second supports are in the assembled configuration.

10. The device according to claim 8 , wherein the circuit breaker includes a first connector, wherein the electric component includes a second connector, wherein the first and second connectors are electrically connectable to one another when the first and second supports are in the assembled configuration, and wherein the first and second connectors connect to one another under an action of at least either one of the controller and the circuit controller when the first and second supports are in the assembled configuration.

11. The device according to claim 1 , wherein the circuit breaker includes a first connector, wherein the electric component includes a second connector, which is controlled by the controller of said electric component, and wherein the first and second connectors are electrically connectable to one another when the first and second supports are in the assembled configuration.

12. The device according to claim 11 , wherein:
the guide comprising a pair of rails, and
each rail comprising a rim which cooperate with the complemental shapes arranged on the first and second supports.

13. A railway vehicle, including:
an aisle,
a high-voltage box, accessible via the aisle, and
the electric switching device according to claim 1 ,
wherein the electric switching device is installed in the high-voltage box when the first and second supports are in the assembled configuration, at least one of the first and second modules of the device being dimensioned to be moved in the aisle when the first and second supports are in the disassembled configuration.
