Description

Dispositif d' alarme antivol pour véhicule bâché ou lieux de stockage sous bâcheAntitheft alarm device for tarpaulins or undercover storage
La présente invention a pour objet un dispositif d'alarme antivol pour véhicule bâché ou lieux de stockage sous bâche .The present invention relates to a burglar alarm device for tarpaulin or storage places under canvas.
La présente invention concerne plus particulièrement le domaine de la sécurisation du transport de marchandises dans des camions ou wagons ferroviaires bâchés, ou de stockage et d'exposition de marchandises sous des chapiteaux par exemple. La présente invention peut toutefois s ' appliquer à la protection de véhicules particuliers de type comportant une capote .The present invention relates more particularly to the field of securing the transport of goods in sheeted railway trucks or wagons, or storage and display of goods under capitals for example. The present invention may, however, apply to the protection of particular vehicles of the type comprising a hood.
On connait déjà des dispositifs d'alarme pour véhicules bâchés comprenant une bâche sécurisée, qui comporte des moyens de détection de lacération, associés à une centrale d'alarme permettant d'émettre un signal avertisseur.We already know alarm devices for sheeted vehicles comprising a secured tarpaulin, which includes laceration detection means, associated with a central alarm for issuing a warning signal.
On connait ainsi des bâches constituées d'une toile en matière isolante parcourue par un conducteur linéaire formant un circuit électrique, la découpe de la toile, et donc dudit conducteur linéaire, provoquant la rupture dudit circuit électrique et le déclenchement d'une alarme.Thus, tarpaulins consisting of a web of insulating material traversed by a linear conductor forming an electrical circuit, the cut of the fabric, and thus of said linear conductor, causing the breaking of said electrical circuit and the triggering of an alarm are known.
Les inconvénients de tels dispositifs consistent essentiellement en ce qu'il est difficile après une effraction de réparer une telle toile, et que d'autre part il peut y avoir des risques de rupture accidentelle du circuit, sans pouvoir déceler l'emplacement de cette rupture, rendant ainsi la bâche inutilisable .The disadvantages of such devices consist essentially in that it is difficult after a break to repair such a fabric, and that on the other hand there may be risks of accidental rupture of the circuit, without being able to detect the location of this break thus rendering the tarpaulin unusable.
Les dispositifs d' alarme pour véhicules bâchés existants présentent également des points faibles au niveau des moyens de connexion entre la bâche sécurisée et la centrale d' alerte , et également entre le tracteur et la semi-remorque ou la remorque lorsqu'il y en a. La présente invention a pour but de proposer un dispositif d'alarme antivol pour véhicule bâché ou lieux bâché ou lieux de stockage sous bâche, du type comprenant une bâche sécurisée qui comporte des moyens de détection de lacération de stockage sous bâche , permettant de remédier aux divers inconvénients précités .The existing tarpaulin alarm devices also have weaknesses in the means of connection between the secured tarpaulin and the central warning system, and also between the tractor and the semi - trailer or the trailer when there is one. . The object of the present invention is to provide an anti-theft alarm device for a tarpaulin-covered vehicle or tarpaulin-covered storage areas, of the type comprising a secured tarpaulin which comprises means for detecting storage laceration in a tarpaulin, making it possible to remedy various aforementioned disadvantages.
Le dispositif d' alarme antivol pour véhicule relié à une centrale d' alarme permettant d' émettre un signal avertisseur par l'intermédiaire de moyens de liaison électrique, caractérisé en ce que ladite bâche consiste en un matériau multi couches et qui comprend deux couches de matériaux conducteurs électriquement, séparées par une couche d'un matériau isolant électriquement, laquelle couche présente des caractéristiques de faible adhésivité auxdites couches de matériaux conducteurs électriquement, et le matériau dont elle est faite présente des caractéristiques d'élasticité.The anti - theft alarm device for a vehicle connected to a control panel for issuing a warning signal by means of electrical connection means, characterized in that said cover consists of a multilayer material and which comprises two layers of electrically conductive materials, separated by a layer of electrically insulating material, which layer has low tack characteristics to said electrically conductive material layers, and the material of which it is made has elasticity characteristics.
La découpe de la bâche du dispositif d'alarme selon l'invention peut être réalisée au moyen d'un objet coupant en matériau conducteur électriquement, ou en matériau non conducteur électriquement .Cutting the cover of the alarm device according to the invention can be achieved by means of a cutting object of electrically conductive material, or of electrically non-conductive material.
Dans le premier cas, l'objet coupant permet de fermer le circuit entre les deux couches de matériaux conducteurs électriquement, et l'alarme est déclenchée.In the first case, the cutting object closes the circuit between the two layers of electrically conductive materials, and the alarm is triggered.
Dans le second cas l'objet non conducteur électriquement est moins tranchant, il permet de découper la toile et les deux couches de matériau conducteur électriquement, tandis que l'élasticité de la couche de matériau isolant rend cette dernière difficilement tranchable, ce qui provoque, du fait également de sa faible adhésivité aux couches de matériaux conducteurs électriquement, son déplacement entre lesdites couches, et provoque la mise en contact de ces dernières, et la fermeture du circuit. On notera qu'on peut également observé ce résultat avec un objet coupant en matériau conducteur. Après une effraction, la réparation de la bâche est réalisée en recréant la couche isolante entre les couches en matériaux conducteurs électriquement avant de reconstituer l'étanchéité de 1 ' ensemble .In the second case the electrically nonconductive object is less sharp, it allows to cut the fabric and the two layers of electrically conductive material, while the elasticity of the layer of insulating material makes the latter difficultly tranchable, which causes, also because of its low adhesiveness to electrically conductive material layers, its movement between said layers, and causes the contacting of the latter, and the closing of the circuit. It will be noted that this result can also be observed with a cutting object made of conductive material. After a break-in, the covering is repaired by recreating the insulating layer between the electrically conductive material layers before reconstituting the tightness of the assembly.
Selon une caractéristique additionnelle du dispositif d' alarme antivol selon l'invention, les couches en matériaux conducteurs électriquement consistent en des feuilles de métal, tel que du cuivre ou de l' aluminium.According to an additional characteristic of the antitheft alarm device according to the invention, the electrically conductive material layers consist of metal sheets, such as copper or aluminum.
Selon une autre caractéristique additionnelle du dispositif d'alarme antivol selon l'invention, les couches en matériaux conducteurs électriquement consistent en des treillis à mailles fines , tissés avec des fils de métal , tel que du cuivre .According to another additional characteristic of the antitheft alarm device according to the invention, the electrically conductive material layers consist of fine mesh meshes, woven with metal wires, such as copper.
Selon une autre caractéristique additionnelle du dispositif d'alarme antivol selon l'invention, l'une des couches en matériaux conducteurs électriquement consiste en un treillis à mailles fines, tissés avec des fils de métal, tel que du cuivre, tandis que l ' autre consiste une feuille de métal , tel que du cuivre ou de l' aluminium.According to another additional characteristic of the antitheft alarm device according to the invention, one of the electrically conductive material layers consists of a fine-mesh trellis, woven with metal wires, such as copper, while the other consists of a sheet of metal, such as copper or aluminum.
Quel que soit le mode de réalisation de la bâche du dispositif d'alarme selon l'invention, ledit dispositif est inefficace si il est possible de déconnecter la bâche et la centrale d'alarme.Whatever the embodiment of the cover of the alarm device according to the invention, said device is ineffective if it is possible to disconnect the cover and the control panel.
Aussi, selon une autre caractéristique additionnelle du dispositif selon l'invention, les moyens de liaison électrique qui relient la bâche à la centrale d'alarme consistent d'une part en des câbles comprenant, outre des fils électriques conducteurs , une gaine extérieure multicouches à savoir deux couches conductrices séparées par une couche isolante et faisant partie d'un circuit relié à la centrale d'alarme, et d'autre part, connectés auxdits fils électriques conducteurs, des moyens de connexion par embrochage comprenant des moyens aptes à permettre la fermeture du circuit en cas de débrochage . Selon une autre caractéristique additionnelle du dispositif d'alarme antivol selon l'invention, les moyens de connexion comportent deux prises , une prise mâle et une femelle , ladite prise femelle comportant des contacts distincts, ainsi que des moyens mobiles aptes à relier lesdits contacts lorsque ladite prise femelle n'est pas accouplée à ladite prise mâle, laquelle comporte des fiches aptes, lors de l'accouplement, d'une part à déplacer lesdits moyens mobiles afin de rompre la liaison entre lesdits contacts , et se connecter auxdits contacts .Also, according to another additional feature of the device according to the invention, the electrical connection means which connect the cover to the alarm center consist on the one hand in cables comprising, in addition to conducting electrical wires, a multilayer outer sheath to namely, two conductive layers separated by an insulating layer and forming part of a circuit connected to the alarm center, and secondly, connected to said conductive electrical wires, plug-in connection means comprising means capable of enabling the closure of the circuit in case of unplugging. According to another additional characteristic of the anti-theft alarm device according to the invention, the connection means comprise two sockets, a plug and a socket, said socket having separate contacts, as well as mobile means able to connect said contacts when said socket is not coupled to said plug, which has suitable plugs, during coupling, on the one hand to move said movable means to break the connection between said contacts, and connect to said contacts.
Selon une autre caractéristique additionnelle du dispositif d'alarme antivol selon l'invention, les couches conductrices des câbles sont connectées aux fils électriques conducteur, en sorte de ne former qu'un seul circuit.According to another additional characteristic of the antitheft alarm device according to the invention, the conductive layers of the cables are connected to the conductive electrical wires, so as to form only one circuit.
Les avantages et les caractéristiques du dispositif d' alarme antivol selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente plusieurs modes de réalisation non limitatifs .The advantages and characteristics of the antitheft alarm device according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents several non-limiting embodiments thereof.

- les figures 5a, 5b et 5c représentent des vues schématiques d'un autre mode de réalisation de moyens de connexion d'un dispositif d'alarme selon l'invention, dans différentes phases d'utilisation.- Figures 5a, 5b and 5c show schematic views of another embodiment of connection means of an alarm device according to the invention, in different phases of use.
En référence à la figure 1, on peut voir une partie d'une bâche 1 d'un dispositif d'alarme selon l'invention. Cette bâche 1 consiste en un matériau multicouches , comprenant deux toiles 10 et 11 constituant les faces externes de la bâche 1 et réalisées à partir de matériau utilisés habituellement, chacune recouverte du côté interne d'une feuille, respectivement 12 et 13, de matériau conducteur électriquement tel que du cuivre ou de l'aluminium, lesquelles feuilles 12 et 13 sont séparées par une couche 14 d'un matériau non conducteur électriquement, qui les maintient isolées l'une de l'autre.With reference to FIG. 1, one can see a part of a cover 1 of an alarm device according to the invention. This sheet 1 consists of a multilayer material, comprising two webs 10 and 11 constituting the outer faces of the sheet 1 and made from material usually used, each covered on the inner side of a sheet, respectively 12 and 13, of conductive material. electrically such as copper or aluminum, which sheets 12 and 13 are separated by a layer 14 of electrically non-conductive material, which keeps them isolated from each other.
La couche 14 est faite, par exemple, de polychlorure de vinyle, de polypropylène ou de polyéthylène, en sorte de présenter des caractéristiques d'élasticité, et de faible adhésivité aux feuilles 12 et 13.The layer 14 is made, for example, of polyvinyl chloride, polypropylene or polyethylene, so as to have characteristics of elasticity, and low adhesiveness to the sheets 12 and 13.
Les deux feuilles 12 et 13 font partie d'un circuit électrique relié à une centrale d'alarme permettant d'émettre un signal avertisseur en cas de la réalisation d'une liaison entre les deux feuilles 12 et 13.The two sheets 12 and 13 form part of an electrical circuit connected to an alarm center making it possible to emit a warning signal in the event of the connection being made between the two sheets 12 and 13.
En référence maintenant à la figure 2 , on peut voir une partie d'une variante 2 d'une bâche d'un dispositif d'alarme selon 1' invention .Referring now to Figure 2, we can see a portion of a variant 2 of a tarpaulin of an alarm device 1 according to the invention.
Cette bâche 2 consiste également en un matériau multicouches, qui comprend deux toiles 20 et 21 constituant les faces externes de la bâche 2 , chacune recouverte du côté interne d' un treillis , respectivement 22 et 23, à mailles fines, tissé avec des fils de métal, tel que du cuivre ou de l'aluminium, tandis qu'une couche 24 de matériau non conducteur électriquement est intercalée entre les deux treillis 22 et 23, et les maintient isolés l'un de l' autre .This sheet 2 also consists of a multilayer material, which comprises two webs 20 and 21 constituting the outer faces of the sheet 2, each covered on the inner side of a lattice, respectively 22 and 23, fine mesh, woven with metal son, such as copper or aluminum, while a layer 24 of electrically nonconductive material is interposed between the two lattices 22 and 23, and maintains isolated from each other.
La couche 24 est constituée également d'un matériau des caractéristiques d'élasticité, et de faible adhésivité aux treillis 22 et 23.The layer 24 is also made of a material of the characteristics of elasticity, and low adhesiveness to the lattices 22 and 23.
Les deux treillis 22 et 23 font partie d'un circuit électrique relié à une centrale d'alarme permettant d'émettre un signal avertisseur en cas de la réalisation d'une liaison entre les deux treillis 22 et 23.The two lattices 22 and 23 form part of an electrical circuit connected to an alarm center making it possible to emit a warning signal in the event of the connection being made between the two lattices 22 and 23.
Ainsi, lors d'une tentative d'effraction par découpe de la bâche 1 ou 2, avec un objet coupant, réalisé en matériau conducteur d'électriquement, celui-ci en entrant en contact simultanément avec les deux feuilles 12 et 13, ou les deux treillis 22 et 23, établit le contact et déclenche l'alarme.Thus, during an attempt to break the sheet 1 or 2 by cutting, with a cutting object, made of electrically conductive material, the latter by coming into contact simultaneously with the two sheets 12 and 13, or the two lattices 22 and 23, establishes the contact and triggers the alarm.
Si l'objet tranchant n'est pas conducteur électriquement, il ne permet pas d'établir le contact entre les deux feuilles 12 et 13, ou les deux treillis 22 et 23. Par contre il est obligatoirement moins coupant qu'un objet conducteur électriquement, et les caractéristiques de la couche 14 ou 24, à savoir d'une part son élasticité qui la rend moins facilement tranchable, et d'autre part sa faible adhésivité aux feuilles 12 et 13, ou aux treillis 22 et 23, qui en facilite la désolidarisation, permettent son arrachement partiel d'entre les feuilles 12 et 13, ou les treillis 22 et 23, et la fermeture du circuit par la mise en contact des feuilles 12 et 13, ou des treillis 22 et 23.If the cutting object is not electrically conductive, it does not make it possible to establish contact between the two sheets 12 and 13, or the two lattices 22 and 23. By cons it is necessarily less cutting than an electrically conductive object , and the characteristics of the layer 14 or 24, namely on the one hand its elasticity which makes it less easily sliced, and on the other hand its low adhesiveness to the sheets 12 and 13, or the lattices 22 and 23, which facilitates the uncoupling, allow its partial tearing of between the sheets 12 and 13, or the lattices 22 and 23, and the closure of the circuit by contacting the sheets 12 and 13, or lattices 22 and 23.
En référence maintenant aux figures 3a, 3b, 3c, 4a, 4b et 4c, et 5a, 5b et 5c, on peut voir trois modes de réalisation de moyens de connexion permettant de relier la bâche 1 ou 2 à une centrale d'alarme.Referring now to FIGS. 3a, 3b, 3c, 4a, 4b and 4c, and 5a, 5b and 5c, three embodiments of the means can be seen. connection to connect the cover 1 or 2 to a central alarm.
La bâche 1 ou 2 est liée à la centrale d'alarme au travers de moyens de liaison tels que des câbles 3 , et de moyens de connexion, et quel que soit le mode de réalisation de ces derniers, les câbles 3 comportent deux fils conducteurs 30 etThe cover 1 or 2 is connected to the alarm center through connection means such as cables 3, and connection means, and whatever the embodiment of the latter, the cables 3 comprise two son drivers 30 and
31, gainés de couches coaxiales, à savoir essentiellement deux couches 32 et 33 réalisées en un matériau conducteur électriquement, séparées par une couche 34 d'un matériau isolant non conducteur électriquement, l'ensemble étant disposé dans une enveloppe 35 en matériau non conducteur électriquement.31, sheathed coaxial layers, namely essentially two layers 32 and 33 made of an electrically conductive material, separated by a layer 34 of an electrically non-conductive insulating material, the assembly being disposed in an envelope 35 of electrically non-conductive material .
Les couches 32 et 33 sont connectées électriquement à la centrale d'alarme, et de préférence aux fils conducteurs, respectivement 30 et 31, au travers de pattes de connexion, respectivement 36 et 37, et font parties du même circuit électrique, en sorte que le sectionnement du câble 3 mette en contact les deux couches 32 et 33, provoquant ainsi la fermeture du circuit et le déclenchement de l'alarme.The layers 32 and 33 are electrically connected to the alarm control panel, and preferably to the conductive wires, respectively 30 and 31, through connection tabs, respectively 36 and 37, and are part of the same electrical circuit, so that the cutting of the cable 3 brings into contact the two layers 32 and 33, thus causing the closure of the circuit and the triggering of the alarm.
Les moyens de connexion représentés sur les figures 3a, 3b, 3c et 4a, 4b et 4c, sont destinés à permettre de connecter et/ou déconnecter une bâche 1 ou 2 de la centrale d' alarme , soit lors de l'arrimage ou le désarrimage d'une semi-remorque au tracteur, soit lors de l'arrimage ou le désarrimage d'une remorque.The connection means shown in Figures 3a, 3b, 3c and 4a, 4b and 4c, are intended to allow to connect and / or disconnect a cover 1 or 2 of the central alarm, either during docking or the unstacking a tractor-trailer, either when securing or unstacking a trailer.
Ces moyens de connexion sont conçus aptes à interdire une déconnexion frauduleuse .These connection means are designed to prohibit a fraudulent disconnection.
Ainsi, on peut voir sur les figures 3a, 3b et 3c, que les moyens de connexion consistent en un ensemble 4 de deux prises , une prise mâle 5 et une prise femelle 6, branchées chacune à l'extrémité d'un câble 3. La prise mâle 5 comporte deux fiches parallèles 50 et 51 montées dans un corps 52, reliées chacune à un fil conducteur, respectivement 30 et 31, et entre ces deux fiches 50 et 51 parallèlement à celle-ci, un doigt 53 en matériau non conducteur électriquement, et plus long que les fiches 50 et 51.Thus, it can be seen in FIGS. 3a, 3b and 3c that the connection means consist of an assembly 4 of two sockets, a plug 5 and a socket 6, each connected to the end of a cable 3. The plug 5 comprises two parallel plugs 50 and 51 mounted in a body 52, each connected to a conductor wire, respectively 30 and 31, and between these two plugs 50 and 51 parallel thereto, a finger 53 of non-conductive material electrically, and longer than the plugs 50 and 51.
La prise femelle 6 comprend deux douilles parallèles 60 et 61, en matériau conducteur, disposées dans un corps creux 62 et destinées chacune à recevoir l'une des fiches 50 ou 51. Le corps 62 comporte également un conduit 63, parallèle aux douilles 60 et 61, disposés en celles-ci et destiné à loger le doigt 53.The socket 6 comprises two parallel bushes 60 and 61, made of conductive material, arranged in a hollow body 62 and each intended to receive one of the plugs 50 or 51. The body 62 also comprises a duct 63, parallel to the bushes 60 and 61, arranged in them and intended to house the finger 53.
La douille 60, respectivement 61, comporte du côté en regard du conduit 63 , une lumière 64 , respectivement 65 , tandis que le conduit 63 comporte en regard de la lumière 64, une lumière 66, et en regard de la lumière 65 , une lumière 67.The bushing 60, respectively 61, has on the opposite side of the duct 63, a light 64, respectively 65, whereas the duct 63 comprises, facing the light 64, a light 66, and facing the light 65, a light 67.
D'autre part, le corps creux 62 renferme deux lames ressort 68 et 69 à chacune desquelles est relié un fil conducteur 30, 31.On the other hand, the hollow body 62 encloses two spring blades 68 and 69 to each of which is connected a conductive wire 30, 31.
Comme on peut le voir de manière plus précise sur la figure 3a, les lames 68 et 69 sont configurées pour, au repos, venir au contact l'une de l'autre dans le conduit 63 en passant par, respectivement, les lumières 66 et 67.As can be seen more precisely in FIG. 3a, the blades 68 and 69 are configured, at rest, to come into contact with each other in the duct 63 via, respectively, the lights 66 and 67.
Sur la figure 3b, lors du rapprochement des prises mâle 5 et femelle 6 , on peut voir que dans un premier temps , avant introduction des fiches 50 et 51 dans les douilles 60 et 61, le doigt 53 pénètre dans le conduit 63 et écarte les lames 68 et 69, rompant ainsi la connexion électrique qui les lie, tout en les repoussant dans douilles 60 et 61 en passant par les lumières 64 et 66.In FIG. 3b, when the male and female receptacles 6 are brought together, it can be seen that, in a first step, before the plugs 50 and 51 are inserted into the sockets 60 and 61, the finger 53 enters the conduit 63 and discards the blades 68 and 69, thus breaking the electrical connection that binds them, while pushing them back into sockets 60 and 61 through the lights 64 and 66.
Sur la figure 3c, on peut voir qu'après leur introduction complète dans les douilles 60 et 61, les fiches 50 et 51 se trouvent au contact, respectivement, des lames 68 et 69, assurant ainsi la connexion entre les deux câbles 3.In FIG. 3c, it can be seen that after their complete introduction into sockets 60 and 61, plugs 50 and 51 in contact with, respectively, blades 68 and 69, thus ensuring the connection between the two cables 3.
Un tel dispositif permet d' assurer la fermeture du circuit lors du débranchement des deux prises 5 et 6.Such a device makes it possible to close the circuit when disconnecting the two sockets 5 and 6.
En référence maintenant aux figures 4a, 4b et 4c, on peut voir un autre mode de réalisation des moyens de connexion, lesquels consistent en un ensemble 7 de deux prises , une prise mâle 8 et une prise femelle 9, branchées chacune à l'extrémité d'un câble 3.Referring now to FIGS. 4a, 4b and 4c, another embodiment of the connection means can be seen, which consist of an assembly 7 of two sockets, a plug 8 and a socket 9, each connected to the end a cable 3.
La prise mâle 8 comporte deux fiches parallèles 80 et 81 montées dans un corps 82, reliées chacune à un fil conducteur, respectivement 30 et 31.The plug 8 has two parallel plugs 80 and 81 mounted in a body 82, each connected to a lead wire, respectively 30 and 31.
La prise femelle 9 comprend deux conduits parallèles 90 et 91, disposées dans un corps creux 92 et destinés chacun à recevoir l'une des fiches 80 ou 81, les conduits 90 et 91 étant débouchés et d'une longueur inférieure à celle des fiches 80 ou 81. Le corps 92 renferme également deux lames ressort 93 et 94 , chacune reliée un fil conducteur 30 et 31, et comportant une extrémité libre, respectivement 95 et 96, passant devant un conduit, respectivement 90 et 91, pour venir s'appliquer en rappel, contre un plot central 97 en matériau conducteur électriquement, apte à réaliser la fermeture du circuit.The socket 9 comprises two parallel ducts 90 and 91 disposed in a hollow body 92 and each intended to receive one of the plugs 80 or 81, the ducts 90 and 91 being open and of a length less than that of the plugs 80 or 81. The body 92 also contains two spring blades 93 and 94, each connected to a conductive wire 30 and 31, and having a free end, respectively 95 and 96, passing in front of a conduit, respectively 90 and 91, to come to apply as a reminder, against a central stud 97 of electrically conductive material, suitable for closing the circuit.
On comprendra, en regardant les figures 4b et 4c, que l'introduction des fiches 80 et 81 dans les conduits 90 et 91 a pour but d'écarter les extrémités libres 95 et 96 des lames 93 et 94, du plot central 97 et ainsi de rompre le circuit, et de réaliser la connexion entre les fiches 80 et 81 et les lames 93 et 94.It will be understood, with reference to FIGS. 4b and 4c, that the insertion of the plugs 80 and 81 into the ducts 90 and 91 is intended to separate the free ends 95 and 96 of the blades 93 and 94, the central stud 97 and thus to break the circuit, and to make the connection between the pins 80 and 81 and the blades 93 and 94.
En référence maintenant aux figures 5a, 5b et 5c, on peut voir une autre variante, où le circuit du câble 3 n'est pas connecté au fils 30 et 31, mais constitue un circuit parallèle, et comporte à cet effet, pour chacune des prises, des moyens de brochage 38 et 39 connectés aux de pattes de connexion, respectivement 36 et 37. With reference now to FIGS. 5a, 5b and 5c, another variant can be seen, in which the circuit of the cable 3 is not connected to the son 30 and 31, but constitutes a parallel circuit, and for this purpose has, for each of the jacks, broaching means 38 and 39 connected to connection lugs, respectively 36 and 37.
