Abstract

The invention relates to: 1) A male safety plug element (2 contacts and a pin) making it possible to prevent any unauthorised connection; the presence of the central pin A prevents the insertion of the plug into any conventional socket; 2) A socket having three holes, two of which are for the electrical contacts and one for safety purposes (connection authorisation).

Description

DESCRIPTION
La présente invention concerne un système utilisable pour faire des montages en électricité et en électronique dans les Etablissements scolaires en s'assurant un maximum de sécurité.DESCRIPTION
The present invention relates to a system usable for making electrical and electronic assemblies in educational establishments while ensuring maximum security.

Ce systeme est dénommé " FICHE DE SECURITE
Actuellement de nombreux montages, soit d'électricité, soit d'électronique, sont réalisés dans les écoles au moyen de fiches qui se branchent sur des boitiers possédant des douilles bananes. Il statère que ces fiches peuvent également se mettre dans une prise de courant classique (écartement de 19 mm entre les trous), droù risque d'accident.This system is called "SAFETY DATA SHEET
Currently many assemblies, either of electricity, or of electronics, are carried out in the schools by means of plugs which are connected on boxes having banana sockets. It states that these plugs can also be put in a standard socket (19 mm spacing between the holes), where there is a risk of accident.

La nouvelle forme donnée à cette fiche permet d'éliminer ce risque, c'est l'objet de cette invention. The new form given to this sheet eliminates this risk, it is the object of this invention.

Cette nouvelle forme consiste simplement en la réalisation d'une fiche de sécurité dont on aura placé entre les fiches un ergot central dont la longueur est suffisante, de sorte qu'en cas d'essais d'introduction de la fiche dans une prise classique, cet ergot empêche l'introduction. This new form simply consists in the production of a safety card, a central lug of which the length is sufficient between the cards, so that in the event of attempts to introduce the card into a conventional socket, this lug prevents introduction.

Par contre, cette fiche est concue pour entrer dans des boitiers à trois trous, le contact se faisant sur les deux douilles latérales. Le principe couvert par cette invention est ce plot central entre les douilles, quelque que soit la forme du plot (carré, rond, etc...). On the other hand, this plug is designed to enter three-hole boxes, the contact being made on the two side sockets. The principle covered by this invention is this central stud between the sockets, whatever the shape of the stud (square, round, etc.).

La figure 1 présente le plot sans douilles, l'élément (A) au centre garantie la sécurité des utilisateurs. Figure 1 shows the stud without sockets, the element (A) in the center guarantees user safety.

La figure 2 présente le plot complet avec ses deux douilles (B et B') pour le contact électrique. Figure 2 shows the complete block with its two sockets (B and B ') for the electrical contact.

La figure 3 présente le plot monté en éclaté. Figure 3 shows the exploded mounted stud.

La figure 4 présente un exemple d'enfichage dans une partie femelle à trois trous, C et C' : trous avec douilles pour le contact électrique,
D : trou pour le plot de sécurité (A) FIG. 4 shows an example of plugging into a female part with three holes, C and C ': holes with sockets for the electrical contact,
D: hole for the safety stud (A)

Claims (3)

REVENDICATIONS 1) Dispositif de fiche électrique ou électronique ( fig. 4 ) pourvue d'un plot central ( À ) en plus des 2 contacts habituels ( B et B' ) assurant à l'utilisateur le maximum de sécurité dans ses branchements. 1) Electrical or electronic plug device (fig. 4) provided with a central stud (A) in addition to the 2 usual contacts (B and B ') ensuring the user maximum security in his connections. 2) Dispositif selon la revendication 1 empêchant tout branchement dans une prise classique, non pourvue d'un trou supplémentaire D ( fig. 4 ) autorisant le contact. 2) Device according to claim 1 preventing any connection in a conventional socket, not provided with an additional hole D (fig. 4) allowing contact. 3) Dispositif selon la revendication 2 caractérisé par le fait que les contacts électriques ne peuvent avoir lieu que si le plot central A a la possibilité d'entrer dans un logement prévu à cet effet ( D ).  3) Device according to claim 2 characterized in that the electrical contacts can only take place if the central block A has the possibility of entering a housing provided for this purpose (D).
