Abstract
Description
La présente invention a pour objet un conducteur électrique destiné, en particulier mais non exclusivement, à constituer une clôture notamment pour l'élevage de ltescargot. The present invention relates to an electrical conductor intended, in particular but not exclusively, to constitute a fence in particular for the breeding of ltescargot.
On a utilisé dans les débuts de l'éclairage électrique des filaments de carbone à l'intérieur d'ampoules sous vide, mais ce corps a été rapidement remplacé par des filaments électriques dont les propriétés conductrices sont très supérieures. In the early days of electric lighting, carbon filaments were used inside vacuum interrupts, but this body was quickly replaced by electric filaments whose conductive properties are much superior.
La présente invention a pour but la réalisation de conducteurs électriques qui soient chimiquement inertes. The object of the present invention is to produce electrical conductors which are chemically inert.
En effet, dans le cas de clôtures électriques pour l'élevage d'escargot, l'atmosphère est nécessairement très humide, le degré hygrométrique atteignant couramment 100 % pendant plus de 12 heures par jour. Avec les conducteurs métalliques traditionnels, il se produit donc un effet d'électrolyse qui se traduit par une oxydation rapide des conducteurs constituant les clôtures de type connu.Indeed, in the case of electric fences for snail farming, the atmosphere is necessarily very humid, the humidity level commonly reaching 100% for more than 12 hours per day. With traditional metal conductors, there is therefore an electrolysis effect which results in rapid oxidation of the conductors constituting the fences of known type.
Selon la présente invention, le conducteur électrique est caractérisé en ce qu'il consiste en du carbone noyé dans une matière synthétique. According to the present invention, the electrical conductor is characterized in that it consists of carbon embedded in a synthetic material.
Le carbone, s'il présente une inertie chimique totale et ne s'oxyde pas en milieu humide, présente en effet l'inconvénient d'être très fragile. Carbon, if it has total chemical inertness and does not oxidize in a humid environment, has the disadvantage of being very fragile.
Or, pour constituer des clôtures électriques, il est nécessaire de conformer le/ou les conducteurs en parallèle autour de l'endroit à protéger. However, to constitute electric fences, it is necessary to conform the / or the conductors in parallel around the place to be protected.
De préférence, le carbone est chargé dans une matière plastique connue sous le nom de RILSAN (marque déposée) fabriquée par ATO CHIMIE. Preferably, the carbon is loaded in a plastic material known under the name of RILSAN (registered trademark) manufactured by ATO CHIMIE.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre d'un mode de réalisation particulier, donné uniquement à titre d'exemple non limitatif, en regard des figures qui représentent
- la fig. 1 une vue d'une partie d'un conducteur selon l'invention
- les fig. 2, 3 et 4 une clôture électrique réalisée avec de tels conducteurs. Other characteristics and advantages of the invention will appear during the description which follows of a particular embodiment, given solely by way of nonlimiting example, with reference to the figures which represent
- fig. 1 a view of part of a conductor according to the invention
- figs. 2, 3 and 4 an electric fence made with such conductors.
Sur la fig. 1, le conducteur est plat et est constitué par une feuille 1 de RILSAN du type SR 100 par exemple chargé à 30 % de fibres de carbone. In fig. 1, the conductor is flat and consists of a sheet 1 of RILSAN of the SR 100 type, for example loaded with 30% carbon fibers.
I1 s'est toutefois avéré au cours de diverses expériences réalisées que la conductibilité d'un tel conducteur était insuffisante. However, it has been found in various experiments that the conductivity of such a conductor is insufficient.
Selon une caractéristique de l'invention, on noie à l'intérieur du RILSAN un fil métallique 2,par exemple en acier inoxydable de 5/10e de mm, lors de la réalisation du conducteur. According to a characteristic of the invention, a metallic wire 2 is drowned inside the RILSAN 2, for example made of stainless steel 5 / 10ths of a mm, during the production of the conductor.
Dans le cas où le feuillard est destiné à constituer une clôture électrique telle que celle qui est représentée sur les figures 2, 3 et 4, l'épaisseur est par exemple de lmm pour une largeur de 5mm. Les conducteurs 1 sont par exemple disposés en parallèle sur une paroi 3 de manière à constituer deux paires de conducteurs qui sont soumises à l'action d'un courant alternatif de 3 à 12 volts par exemple. In the case where the strip is intended to constitute an electric fence such as that which is represented in FIGS. 2, 3 and 4, the thickness is for example 1 mm for a width of 5 mm. The conductors 1 are for example arranged in parallel on a wall 3 so as to constitute two pairs of conductors which are subjected to the action of an alternating current of 3 to 12 volts for example.
En effet, dans le cas d'élevage d'escargots, on a constaté qu'une seule paire de conducteurs ne constituait pas une dissuasion absolue. Indeed, in the case of snail farming, it has been found that a single pair of conductors does not constitute an absolute deterrent.
Les conducteurs 1 sont fixés sur la paroi 3 au moyen d'un adhésif par exemple. The conductors 1 are fixed to the wall 3 by means of an adhesive for example.
Sur la figure 4, la clôture électrique est disposée à la partie supérieure d'un bac d'élevage d'escargots 4 qui est représenté en vue partiellement coupée. In Figure 4, the electric fence is arranged at the top of a snail breeding tank 4 which is shown in partially cut view.
I1 va de soi que des modifications peuvent être apportées au mode de réalisation qui vient d'être décrit, notamment par substitution de moyens techniques équivalents, sans sortir pour celà du cadre de la présente invention. It goes without saying that modifications can be made to the embodiment which has just been described, in particular by substitution of equivalent technical means, without departing from the scope of the present invention.
