Abstract

A system for multiple connection of switchgear devices comprising a first connection plane comprising at least one plug-in socket designed to receive a switchgear device pluggable in a plug-in direction. Said system comprises a second protection plane comprising a removable cover provided with at least one opening for the control means of said switchgear device to pass through. The removable cover comprises at least a first pressing area designed to press against a second pressing area of at least one switchgear device, pressing of the first pressing area on the second pressing area at the time the removable cover is positioned providing a holding force of said at least one switchgear device.

Claims

1. System for multiple connection of switchgear devices for protection of a current line, system comprising:

a first connection plane comprising at least one plug-in socket designed to receive a switchgear device engaging in a plug-in direction;

a second protection plane comprising a removable cover provided with at least one opening for the control means of said switchgear device to pass through;

said removable cover comprising at least a first pressing area designed to

press against a second pressing area of at least one switchgear device, connection system comprising at least one intermediate buffer part positioned between said at least first and second pressing areas, the intermediate buffer part enabling a uniform distribution of a holding force over the whole set of switchgear devices at the time the removable cover is positioned on said at least one switchgear device in the plug-in socket.

2. Multiple connection system according to claim 1, wherein the intermediate buffer part is positioned on said at least first pressing area or on said at least second pressing area.

3. Multiple connection system according to claim 1, wherein said at least one intermediate buffer part is made from deformable material.

4. Multiple connection system according to claim 1, wherein said holding force comprises a main component directed in the plug-in direction.

5. Multiple connection system according to claim 1, wherein said at least first pressing area is located on the periphery of each opening of the removable cover.

6. Multiple connection system according to claim 5, wherein the periphery of each opening is of cylindrical shape and is designed to engage on a tapered shape of the second pressing area of a switchgear device to achieve progressive application of the holding force.

7. Multiple connection system according to claim 6, wherein the intermediate buffer part comprises a deformable O-ring.

8. Multiple connection system according to claim 1, wherein said at least one plug-in socket is connected to a power connector via at least one conductor comprising printed circuit tracks arranged on the first connection plane, said connector being connected to said printed circuit tracks.

9. Switchgear device designed to be connected to a plug-in socket of a multiple connection system according to claim 6, comprising a second pressing area of tapered shape, said tapered shape being designed to press against the cylindrical first pressing area of the removable cover.
