La présente invention concerne une cosse de masse destinée à un appareil muni d'au moins un élément en tôle, la cosse comprenant une plaque dite principale munie, d'un côté, de moyens pour y attacher un fil de masse, et une partie attachée à la plaque principale et formant avec elle une pince capable de serrer la dite tôle.The present invention relates to a ground terminal intended for an appliance provided with at least one sheet metal element, the terminal comprising a so-called main plate provided with a side, means for attaching a ground wire, and a part attached to the plate main and forming with it a clamp capable of clamping said sheet.

L'invention concerne en outre un appareil muni d'au moins un élément en tôle, ou bien un luminaire muni d'un réflecteur en tôle, ainsi qu'un procédé pour mettre en place une cosse de masse dans un tel appareil.The invention further relates to an apparatus provided with at least one sheet metal element, or a luminaire fitted with a sheet metal reflector, as well as a method for setting up a ground terminal in such a device.

Une cosse de masse selon le préambule ci-dessus est connue du document US 4,993,959 (Randolph). Selon ce document, la cosse comprend une plaque pliée en U de façon à former des parois opposées pour s'engager à force dans une tôle, avec un fil de connexion décalé par rapport à l'arrangement en U.A ground terminal according to the preamble above is known from the document US 4,993,959 (Randolph). According to this document, the terminal includes a U-folded plate of so as to form opposite walls to forcely engage in a sheet, with a wire connection offset from the U-shaped arrangement.

Un objet de l'invention est de simplifier la mise en place de la cosse.An object of the invention is to simplify the installation of the terminal.

A cet effet, la partie formant pince est une lame élastique dont le point d'attache à la plaque principale est situé d'un côté de cette plaque opposé à celui où sont situés les moyens pour assujettir un fil de masse.For this purpose, the clamp part is an elastic blade whose point of attachment to the main plate is located on one side of this plate opposite to that where the means for securing a ground wire.

De préférence, la lame élastique est découpée dans la plaque principale, et les moyens pour attacher un fil de masse sont des moyens de sertissage.Preferably, the elastic blade is cut from the main plate, and the means for attaching a ground wire are crimping means.

Avantageusement, la cosse comporte un crochet embouti dans la plaque principale du côté de cette plaque opposé à celui où sont situés les moyens pour assujettir un fil de masse, crochet pointant dans une direction opposée au côté où ces moyens sont situés.Advantageously, the terminal has a hook stamped in the main plate of the side of this plate opposite to that where the means for securing a wire are located mass, hook pointing in a direction opposite to the side where these means are located.

Dans un appareil, par exemple un luminaire, comprenant une tôle devant être reliée à la terre, la tôle comporte un orifice dans lequel est fixée une cosse de masse selon l'invention.In a device, for example a luminaire, comprising a sheet to be connected to the earth, the sheet has an orifice in which a ground terminal is fixed according to the invention.

De préférence, une dimension de l'orifice est pratiquement égale à la longueur de la lame élastique formant pince.Preferably, a dimension of the orifice is practically equal to the length of the elastic blade forming a clamp.

Pour mettre en place une cosse selon l'invention, on introduit la susdite partie formant pince dans un orifice de la tôle, et on engage la pince dans la tôle en tirant sur le fil de masse.To set up a terminal according to the invention, the above-mentioned part is introduced. clamp in an orifice of the sheet, and we engage the clamp in the sheet by pulling on the wire mass.

Ceci présente en outre l'avantage qu'en tirant, on ne risque pas de déformer la tôle, et que le montage peut s'effectuer sans outil.This also has the advantage that by pulling, there is no risk of deforming the sheet, and that assembly can be carried out without tools.

Ces aspects de l'invention ainsi que d'autres aspects plus détaillés apparaítront plus clairement grâce à la description suivante d'un mode de réalisation constituant un exemple non limitatif.These aspects of the invention as well as other more detailed aspects will appear more clearly through the following description of an embodiment constituting a nonlimiting example.

La figure 1 représente schématiquement en perspective une cosse de masse selon l'invention. Figure 1 shows schematically in perspective a ground terminal according the invention.

La figure 2 représente une cosse de masse selon l'invention, mise en place dans une tôle, vue en coupe.FIG. 2 represents a ground terminal according to the invention, placed in a sheet metal, section view.

La figure 3 représente schématiquement en coupe un luminaire muni d'une cosse de masse selon l'invention.Figure 3 shows schematically in section a luminaire provided with a terminal mass according to the invention.

La cosse de masse représentée sur la figure 1 comprend une plaque 8 dite principale munie, du côté indiqué par la flèche 12, de moyens pour y attacher un fil de masse, ici des moyens de sertissage 7.The ground terminal shown in FIG. 1 comprises a so-called main plate 8 provided, on the side indicated by arrow 12, with means for attaching a ground wire to it, here crimping means 7.

Une partie 9 est attachée à la plaque principale et forme avec elle une pince. La partie formant pince est une lame élastique 9 dont le point d'attache à la plaque principale est situé du côté 14 de cette plaque, opposé à celui (flèche 12) où sont situés les moyens 7 pour assujettir un fil de masse. La lame élastique 9 est plus petite que la plaque principale 8 et est découpée dans la plaque principale.A part 9 is attached to the main plate and forms with it a clamp. The part forming a clamp is an elastic blade 9 whose point of attachment to the main plate is located on the side 14 of this plate, opposite to that (arrow 12) where the means 7 are located to secure a ground wire. The elastic blade 9 is smaller than the plate main 8 and is cut from the main plate.

Des cosses sont de préférence livrées en bande, à partir de laquelle une machine automatique, connue en soi, sertit le fil de masse sur la cosse et sépare la cosse de ses voisines, ce qui laisse des traces d'éléments 13A, 13B, qui reliaient les cosses les unes aux autres avant la découpe.Lugs are preferably supplied in strips, from which a machine automatic, known per se, crimps the ground wire on the terminal and separates the terminal from its neighboring, leaving traces of elements 13A, 13B, which connected the terminals to others before cutting.

La plaque principale comporte un crochet 15 embouti du côté de cette plaque opposé à celui où sont situés les moyens 7 pour assujettir un fil de masse, crochet 15 pointant dans une direction opposée au côté où ces moyens sont situés, c'est-à-dire vers l'élément 13B.The main plate has a hook 15 stamped on the side of this opposite plate to that where the means 7 are located for securing a ground wire, hook 15 pointing in a direction opposite to the side where these means are located, i.e. towards item 13B.

Sur la figure 2, où les mêmes éléments portent les mêmes références, la cosse est représentée mise en place sur une tôle 10, et munie d'un fil de connexion 5, serti dans les pattes 7. Un orifice 6 est ménagé dans la tôle 10, au travers duquel la lame 9 est passée. La dimension de cet orifice, dans la direction de la longueur de la cosse, est pratiquement égale à la longueur de la lame élastique formant pince. Un crochet 11, embouti dans la lame 9, assure un meilleur contact et maintient la cosse en place. Le crochet 15 empêche aussi la cosse de se déplacer dans le sens qui pourrait la faire échapper hors de l'orifice.In Figure 2, where the same elements have the same references, the terminal is shown placed on a sheet 10, and provided with a connection wire 5, crimped in the legs 7. An orifice 6 is formed in the sheet metal 10, through which the blade 9 is past. The dimension of this opening, in the direction of the length of the terminal, is practically equal to the length of the elastic blade forming a clamp. A hook 11, stamped in the blade 9, ensures better contact and keeps the terminal in place. The hook 15 also prevents the terminal from moving in the direction that could make it escape out of the orifice.

Le luminaire de la figure 3 est muni d'un boítier 1 en tôle, d'un réflecteur 2 en tôle, par exemple une tôle d'aluminium de 0,4 mm d'épaisseur, et d'une lampe 3. Un orifice 6 est prévu dans la tôle du réflecteur 2 pour y introduire la lame d'une cosse de masse 4. Pour mettre en place cette cosse de masse, on introduit la lame 9 dans l'orifice 6 de la tôle, et on engage la pince de la cosse dans la tôle en tirant sur le fil de masse 5, ici en tirant vers le haut. N'importe quel autre appareil, muni d'une tôle devant être reliée à la terre, pourrait être équipé d'une cosse de masse de la même manière.The luminaire of FIG. 3 is provided with a box 1 made of sheet metal, a reflector 2 made of sheet metal, for example an aluminum sheet 0.4 mm thick, and a lamp 3. A hole 6 is provided in the sheet of reflector 2 to introduce the blade of a ground lug 4 into it. To install this ground terminal, the blade 9 is introduced into the orifice 6 of the sheet, and we engage the clamp of the terminal in the sheet by pulling on the ground wire 5, here in pulling up. Any other device with a sheet to be connected to the earth, could be fitted with a ground lug in the same way.
