La présente invention concerne un dispositif de pro-tection mécanique des connecteurs électr:iques d'ensembles electroniques de puissancc rc~roiclis par un hyclrocarbure fluorc et notamment clcs dispositifs disposés à bord de matériels ~erroviaires ou routicrsO
On sait que les enceintes contenarlt un hydrocarbure fluoré, dans le but de reEroidir des semiconducteurs de puissance et leurs accessoires disposés à l'interieur de l'enceinte, pos-sèdent des connecteurs exterieurs sur le couvercle de l'enceinte.
~usqu'à présent, ces connecteurs électriques exposés a l'air libre, soit sur la toiture du véhicule,soit sous caisse, etaient soumis à toutes les perturba-tions atmospheriques, pluie, neige ou poussières. Cette disposition a pour inconvenient de susciter dans ces conditions, un amorçage electrique entre les connecteurs et la masse.
Le dispositif selon la présente invention remédie à
cet inconvénient. En effet, il assure une protection accrue et permet le nettoyage au jet d'eau de l'ensemble sans crainte de court-circuit. -La presente invention propose, en combinaison~
- une enceinte contenant des ensembles electroniques ~ de puissance refroidis par un hydrocarbure, ; - un support sous-jacent à l'enceinte et portant des rails guide, l'enceinte etant située sur les rails guide et mobile par rapport au support, ; - un couvercle posé sur une extrémité de l'enceinte, - des connecteurs électriques multiple, chacun des connecteurs incluant une portion femelle passant a travers ledit couvercle, - une boîte ~ borne incluant un pla-teau isolant fixe situe face au couvert et espacé de ce dernier, les connecteurs électriques comprenant une partie mâle passant à travers le B ~

The present invention relates to a device for pro-mechanical detection of electrical connectors of assemblies power electronics rc ~ roiclis by a fluorocarbon and in particular all the devices on board equipment ~ rail or routicrsO
We know that the enclosures contain a hydrocarbon fluorinated, in order to cool power semiconductors and their accessories arranged inside the enclosure, pos-have external connectors on the enclosure cover.
~ Until now, these electrical connectors exposed to air free, either on the roof of the vehicle or under the body, were subject to all atmospheric disturbances, rain, snow or dust. This provision has the disadvantage of causing under these conditions, an electrical ignition between the connectors and the mass.
The device according to the present invention remedies this disadvantage. Indeed, it provides increased protection and allows cleaning with water jet without fear short circuit. -The present invention proposes, in combination ~
- an enclosure containing electronic assemblies ~ power cooled by a hydrocarbon, ; - a support underlying the enclosure and bearing guide rails, the enclosure being located on the guide and mobile rails in relation to the support, ; - a cover placed on one end of the enclosure, - multiple electrical connectors, each of connectors including a female portion passing through said lid, - a terminal box including a fixed insulating plate located opposite the cover and spaced from it, the connectors electrical including a male part passing through the B ~

Referring to the attached diagrams 1 to 3 we will describe below an example of implementation of the first sente invention, example gives by way of illustration and by no means limiting. The same elements represented on several of these figures relate to all those ~ the same references.
Figure 1 shows a top view partially cut from two speakers plugged into a bolte ~ terminals as well as their supports.

Un couvercle 5 de l'enceinte 1 en matière isolante comporte des connecteurs tels que 6 dont le role est de conduire les diverses especes de courant (alternatif, continu, pulse) vers les ensem-` bles electroniques ou en provenance de ceux-ci. Les connecteurs tels que 6 sont relies a des bornes telles que 7 disposees sur ; un plateau isolant 8 appartenant a une boîte ~ bornes 9 etanche. ~-2, the base of which is capable of sliding in rails 3 and 4.
