Abstract

The blocks have inward spikes to perforate plastic coating and ensure electrical connection between wires. The device consists of a pair of jaws (3,4) which are intended to make a sandwich on either side of a wire mesh, the mesh being formed of two sets of wires (1; 2,2') in perpendicular directions. The inward facing surfaces of the jaws have channels (5,6a) to receive the wires of the mesh. At intervals along these channels there are inwardly directed points (7) which serve to perforate the insulating plastic covering on the wires and make electrical connection with the wire itself. The two jaws are held together by a bolt passing through the two components. The jaws and the points are made from a material which is a good electrical conductor.

Description

DISPOSITIF DE LIAISON EQUIPOTENTIELLE POUR PANNEAUX EN
TREILLIS DE FILS PLASTIFIES
La présente invention a trait aux panneaux en treillis formés de fils métalliques recouverts d'un revtement protecteur en matière plastique et notamment aux panneaux de ce type utilisés comme clôtures.EQUIPOTENTIAL CONNECTION DEVICE FOR PANELS IN
PLASTIC WIRE MESH
The present invention relates to lattice panels formed of metal wires covered with a protective coating of plastic material and in particular to panels of this type used as fences.

Ce type de panneau peut poser des problèmes lorsqu'il est nécessaire ou souhaitable, en particulier pour des raisons techniques ou de sécurité, de mettre les panneaux individuels à un mme potentiel électrique, notamment si l'on veut mettre à la terre par exemple une clôture de ce type. This type of panel can cause problems when it is necessary or desirable, in particular for technical or safety reasons, to put the individual panels at the same electrical potential, in particular if it is desired to ground for example a fence of this type.

Dans ce cas particulier, la mise à la terre de la clôture n'est pas évidente car les panneaux individuels sont isolés électriquement par le gainage de plastique entourant les fils du treillis. In this particular case, the earthing of the fence is not obvious since the individual panels are electrically insulated by the plastic sheathing surrounding the wires of the trellis.

L'invention vise précisément à résoudre ce problème en proposant des moyens simples permettant de réaliser une liaison équipotentielle entre deux panneaux, entre un panneau et un dispositif de mise à la terre, ou bien encore entre des fils d'un mme panneau. The invention aims precisely to solve this problem by proposing simple means enabling an equipotential connection to be made between two panels, between a panel and an earthing device, or even between wires of the same panel.

A cet effet, l'invention a pour objet un dispositif de liaison équipotentielle pour panneaux en treillis de fils plastifiés, caractérisé en ce qu'il est constitué de deux mâchoires susceptibles de prendre en sandwich au moins deux fils, respectivement de trame et de chaîne, d'un panneau, au droit de leur croisement, lesdites mâchoires comportant un moyen de serrage approprié et, sur leur face tournée vers les fils, des gorges de logement de ces derniers, munies d'aspérités susceptibles de perforer le revtement de plastique des fils lors du serrage des mâchoires, ces dernières ainsi que les aspérités étant réalisées en un matériau bon conducteur de l'électricité. To this end, the subject of the invention is an equipotential bonding device for lattice panels of plasticized wires, characterized in that it consists of two jaws capable of sandwiching at least two wires, of weft and warp respectively. , of a panel, in line with their crossing, said jaws comprising an appropriate clamping means and, on their face facing the wires, housing grooves of the latter, provided with roughness capable of perforating the plastic coating of the wires when tightening the jaws, the latter as well as the asperities being made of a material which is a good conductor of electricity.

Un tel dispositif assure ainsi la liaison électrique entre les deux fils du treillis. Such a device thus ensures the electrical connection between the two wires of the trellis.

Avantageusement, les mâchoires comportent plusieurs gorges pour accueillir deux fils de trame parallèles et deux fils de chaîne parallèles, appartenant au mme panneau ou à deux panneaux superposés, toutes les gorges ou une partie seulement comportant des aspérités. Advantageously, the jaws comprise several grooves for accommodating two parallel weft threads and two parallel warp threads, belonging to the same panel or to two superimposed panels, all of the grooves or only a part comprising asperities.

Lorsqu'une liaison de mise à la terre est envisagée, les mâchoires sont munies d'un moyen approprié de connexion électrique par exemple à une tresse ou une barrette d'un circuit de mise à la terre. When an earthing connection is envisaged, the jaws are provided with an appropriate means of electrical connection, for example to a braid or a bar of an earthing circuit.

* Figure 1 is a partial view of two superimposed trellis panels

Sur les figures 1 et 2, on a représenté partiellement un fil de trame 1 et un fil de chaîne 2 d'un premier panneau en treillis constitué de fils ronds, métalliques recouverts d'une gaine protectrice de matière plastique. FIGS. 1 and 2 partially show a weft thread 1 and a warp thread 2 of a first lattice panel made up of round, metallic threads covered with a protective sheath of plastic.

Un tel panneau est un panneau du commerce. One such panel is a commercial panel.

En 1'et 2'respectivement sont représentés un fil de trame et un fil de chaîne d'un second panneau, identique au premier et superposé à lui, les fils de trame 1,1'étant dans un mme plan, cependant que les fils de chaîne 2, 2'sont (figure 2) disposés de part et d'autre des fils de trame. In 1 and 2 respectively are shown a weft thread and a warp thread of a second panel, identical to the first and superimposed on it, the weft threads 1,1 'being in the same plane, while the threads warp 2, 2 'are (Figure 2) arranged on either side of the weft son.

Le dispositif de l'invention comprend deux mâchoires 3 et 4 assemblables de façon à emprisonner, dans le mode de réalisation représenté, quatre croisements de fils. The device of the invention comprises two jaws 3 and 4 which can be assembled so as to trap, in the embodiment shown, four crossings of wires.

A cet effet, la face interne de chaque mâchoire 3,4, de forme générale parallélépipédique, est munie (figures 2 à 7) d'une première gorge 5 à fond hémi-cylindrique pour accueillir un fil de chaîne (2 ou 2') de l'un des panneaux et d'une paire de gorges parallèles 6a et 6b de forme cylindrique pour accueillir les deux fils de trame 1 et 1'des deux panneaux. To this end, the internal face of each jaw 3,4, of generally parallelepipedal shape, is provided (FIGS. 2 to 7) with a first groove 5 with a semi-cylindrical bottom to accommodate a warp thread (2 or 2 ′) of one of the panels and of a pair of parallel grooves 6a and 6b of cylindrical shape to accommodate the two weft threads 1 and 1 of the two panels.

Dans le mode de réalisation illustré, seules les gorges 6a et 6b sont munies sur leur fond d'aspérités en forme de picots 7 dirigés vers le centre du fil reçu dans la gorge. In the illustrated embodiment, only the grooves 6a and 6b are provided on their bottom with asperities in the form of spikes 7 directed towards the center of the wire received in the groove.

La gorge 5 pourrait bien entendu tre également munie de tels picots 7. The groove 5 could of course also be provided with such pins 7.

Les mâchoires 3,4 sont munies en leur centre d'un passage pour la réception d'un système de fixation-serrage, par exemple un boulon et un écrou, la mâchoire 3 comportant par exemple (figures 5 à 7) un perçage cylindrique 8 débouchant, côté extérieur, sur un chambrage hexagonal 9 pour recevoir la tte d'un boulon. The jaws 3,4 are provided in their center with a passage for the reception of a fixing-tightening system, for example a bolt and a nut, the jaw 3 comprising for example (FIGS. 5 to 7) a cylindrical bore 8 opening, on the outside, on a hexagonal recess 9 to receive the head of a bolt.

Les mâchoires 3,4, y compris les picots 7, sont en un mme matériau métallique bon conducteur de l'électricité. The jaws 3,4, including the pins 7, are made of the same metallic material which is a good conductor of electricity.

En position prt au serrage des mâchoires 3,4 (figure 4), les picots 7 ont leur pointe en contact avec la gaine plastique (non représentée) enveloppant les fils 1,1'et les faces internes en regard 3a et 4a (figure 2) des mâchoires sont à distance, en sorte qu'au serrage des mâchoires, les picots 7 puissent traverser les gaines plastiques et leurs pointes s'écraser contre les fils métalliques, assurant ainsi un parfait contact électrique entre les fils et les mâchoires, elles-mmes reliées électriquement, via le dispositif de boulonnage (non représenté) et/ou par le contact physique direct des faces en regard 3a, 4a desdites mâchoires. In the ready position for clamping the jaws 3,4 (FIG. 4), the pins 7 have their tips in contact with the plastic sheath (not shown) enveloping the wires 1,1 ′ and the facing internal faces 3a and 4a (FIG. 2 ) the jaws are at a distance, so that when the jaws are tightened, the pins 7 can pass through the plastic sheaths and their tips crush against the metal wires, thus ensuring perfect electrical contact between the wires and the jaws, same electrically connected, via the bolting device (not shown) and / or by direct physical contact with the facing faces 3a, 4a of said jaws.

Ainsi, une liaison équipotentielle est réalisée entre les fils 1 et 1'des deux panneaux.  Thus, an equipotential bonding is carried out between the wires 1 and 1 of the two panels.

Les mâchoires 3 et 4 du mode de réalisation représenté sont identiques et placées tte-bche. The jaws 3 and 4 of the embodiment shown are identical and placed head to tail.

Si les gorges 5 sont également munies de picots 7, la liaison équipotentielle sera assurée entre les fils 1,1', 2 et 2'. If the grooves 5 are also provided with pins 7, the equipotential bonding will be ensured between the wires 1,1 ′, 2 and 2 ′.

Les fils 1,1'et 2,2'peuvent appartenir à un mme panneau, auquel cas les deux mâchoires comporteront deux gorges de réception de deux fils de trame (ou de chaine), mais seulement l'une comportera deux gorges de réception de deux fils de chaîne (ou de trame), les fils de trame étant d'un mme côté des fils de chaîne. The wires 1,1 ′ and 2,2 ′ can belong to the same panel, in which case the two jaws will have two grooves for receiving two weft (or warp) wires, but only one will have two grooves for receiving two warp (or weft) threads, the weft threads being on the same side of the warp threads.

Les mâchoires 3,4 peuvent couvrir un plus grand nombre de croisements de fils appartenant à un mme panneau ou à deux panneaux superposés. The jaws 3, 4 can cover a greater number of crossings of wires belonging to the same panel or to two superimposed panels.

Dans le cas d'un seul panneau, les mâchoires peuvent n'intéresser qu'un seul croisement en sorte de ne relier équipotentiellement qu'une seule paire de fils, de trame et chaîne. In the case of a single panel, the jaws may be of interest for only one crossing so as to equipotentially connect only one pair of wires, weft and warp.

Bien entendu, dans tous les cas, la paire de mâchoires 3,4 peut tre équipée pour tre reliée à un dispositif de mise à la terre, par exemple à une tresse ou barrette de circuit de terre. Of course, in all cases, the pair of jaws 3, 4 can be equipped to be connected to an earthing device, for example to a braid or bar of an earth circuit.

Plusieurs paires de mâchoires 3,4 peuvent tre disposées sur un mme panneau ou paire de panneaux superposés pour multiplier le nombre de connexion entre fils. Several pairs of jaws 3, 4 can be placed on the same panel or pair of superposed panels to multiply the number of connections between wires.

Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les formes et dimensions des mâchoires 3,4, les nombre, forme et dimensions des gorges 5,6 réceptrices de fils, la nature des aspérités, picots 7 ou analogues ménagés dans tout ou partie desdites gorges, les moyens de serrage des mâchoires, ainsi que les moyens de liaison de ces dernières à un circuit électrique externe, de mise à la terre ou autre.  Finally, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all the variants thereof, in particular as regards the shapes and dimensions of the jaws 3, 4, the numbers, shape and dimensions of the grooves 5,6 receiving the wires, the nature of the asperities, pins 7 or the like formed in all or part of the said grooves, the means for clamping the jaws, as well as the means for connecting the latter to an external electrical circuit, grounding or other.
