Description

L'invention concerne le raccordement de câble électrique isolé avec perforation d'isolant notamment le raccordement d'un conducteur dérivé sur un câble principal.The invention relates to the connection of insulated electrical cable with insulation perforation, in particular the connection of a branched conductor to a main cable.

On connaît des moyens de connexion ou de dérivation pour câbles électriques isolés par une couche de matière plastique où le contact entre le ou les conducteurs est établi par perforation forcée de la couche isolante au moyen d'un corps métallique conducteur extérieur au câble et comportant des aspérités appropriées capables de traverser la couche isolante du ou des câbles. Ces dispositifs comprennent généralement une cage ou étrier, éventuellement démontable, venant enserrer dans son intérieur le ou les câbles électriques à l'endroit où auront à s'exercer les efforts requis pour faire pénétrer les aspérités du corps métallique intermédiaire au travers de la couche isolante et établir ainsi la connexion. Il est demandé à ce corps intermédiaire conducteur dont la face en regard du câble est munie de dents souvent taillées dans sa masse, de jouer le double rôle, de moyen de percement de la couche isolante, de récepteur et transmetteur de la poussée mécanique nécessaire pour ce percement ainsi que de collecteur du courant électrique venant des diverses aspérités arrivées au contact du conducteur sous- jacent.Connection or branching means are known for electrical cables insulated by a layer of plastic material where the contact between the conductor (s) is established by forced perforation of the insulating layer by means of a conductive metal body external to the cable and comprising suitable asperities capable of passing through the insulating layer of the cable (s). These devices generally include a cage or stirrup, possibly removable, enclosing in its interior the electrical cable or cables at the place where the forces required to exert the roughness of the intermediate metallic body will have to penetrate through the insulating layer. and thus establish the connection. This intermediate conductive body, the opposite face of the cable is provided with teeth often cut in its mass, is asked to play the double role, of means of piercing the insulating layer, of receiver and transmitter of the mechanical thrust necessary for this piercing as well as the collector of the electric current coming from the various asperities arrived in contact with the underlying conductor.

Les dispositifs connus de connexion électrique par perforation d'isolant ne comportent pas un moyen simple de contrôle de la perforation de l'isolant. D'autre part l'étanchéité est mal ou pas assu rée.Known devices for electrical connection by perforation of insulation do not include a simple means of controlling the perforation of the insulation. On the other hand, the seal is poorly or not ensured.

Un but de l'invention est de fournir un dispositif de raccordement réalisant un contrôle de la course de perforation de l'isolant pour éviter la détérioration des brins du câble lors d'un serrage trop important de la vis de fixation et ceci quelle que soit la section du câble dans une gamme déterminée.An object of the invention is to provide a connection device carrying out a control of the perforation stroke of the insulation to avoid deterioration of the cable strands during excessive tightening of the fixing screw and this whatever the section of the cable in a determined range.

Un dispositif de raccordement selon les modes de réalisation décrits est isolé et étanche à l'eau quelle que soit la section du câble dans une gamme déterminée.A connection device according to the described embodiments is insulated and watertight regardless of the section of the cable in a determined range.

L'invention a pour objet un dispositif de raccordement de câble isolé par perforation d'isolant comportant des mâchoires munies de dents pour la perforation d'isolant comportant des mâchoires munies de dents pour la perforation d'isolant lors de la mise en place du câble dans le dispositif de raccordement, comme décrit selon le document de brevet FR-A-2 128 011, et caractérisé par le fait qu'il comporte deux parties en forme de mâchoire destinées à enserrer le câble et munies de moyens d'encliquetage venant s'accrocher l'un sur l'autre pour réaliser le positionnement du dispositif de raccordement sur le câble par simple encliquetage et des moyens de perforation d'isolant à serrage par vis et à course limitée pour réaliser la perforation de l'isolant du câble jusqu'au contact des dentures avec les brins conducteurs du câble.The invention relates to an insulated cable connection device by perforation of insulation comprising jaws provided with teeth for the perforation of insulation comprising jaws provided with teeth for perforation of insulation during the installation of the cable in the connection device, as described according to patent document FR-A-2 128 011, and characterized in that it comprises two jaw-shaped parts intended to grip the cable and provided with latching means coming from '' hook one on the other to achieve the positioning of the connection device on the cable by simple snap-fastening and insulation perforation means with screw tightening and limited stroke to perforate the insulation of the cable up to '' in contact with the teeth with the conductive strands of the cable.

Tel que représenté sur les figures 1 à 5, le dispositif de raccordement de câble comprend un boîtier étanche en deux parties 11, 12 qui peuvent être solidarisées par un jonc 10. La partie inférieure 11 renferme une mâchoire fixe 13 comportant une denture fixe 14 ; la partie supérieure 12 renferme une mâchoire mobile 15 qui renferme une denture mobile 16 déplaçable à l'intérieur de la mâchoire 15 au moyen d'une vis 17 comportant une tête de vis 18 recouverte d'un bouchon isolant 19.As shown in Figures 1 to 5, the cable connection device comprises a sealed housing in two parts 11, 12 which can be secured by a rod 10. The lower part 11 contains a fixed jaw 13 having a fixed toothing 14; the upper part 12 contains a movable jaw 15 which encloses a movable toothing 16 movable inside the jaw 15 by means of a screw 17 comprising a screw head 18 covered with an insulating plug 19.

La mâchoire mobile 15 est munie de deux bras 21, 22 dont l'extrémité 23 crantée est destinée à venir s'accrocher dans des crans 24 de la mâchoire fixe 13. La denture mobile 16 est munie de bras latéraux 25, 26 destinés à coulisser le long du corps de la denture fixe 14 lors du serrage de la vis 17.The movable jaw 15 is provided with two arms 21, 22, the notched end 23 of which is intended to hang in notches 24 of the fixed jaw 13. The movable teeth 16 are provided with lateral arms 25, 26 intended to slide along the body of the fixed toothing 14 when the screw 17 is tightened.

Les deux dentures 14 et 16 sont placées sur le câble principal 27 et pénètrent dans l'isolant 28 du câble lors du serrage de la vis 17, (voir fig. 4).The two teeth 14 and 16 are placed on the main cable 27 and penetrate into the insulator 28 of the cable when the screw 17 is tightened (see fig. 4).

La course du serrage de la vis 17 est limitée par deux butées 29, 30 portées respectivement par les bras 21, 22 de la mâchoire mobile 15 et par la denture mobile 16 qui servent de butées de fin de course.The tightening stroke of the screw 17 is limited by two stops 29, 30 carried respectively by the arms 21, 22 of the movable jaw 15 and by the movable teeth 16 which serve as end of stroke stops.

L'étanchéité du boîtier sur le câble 27 est assurée par des languettes 31, 32 de la partie supérieure qui viennent s'imbriquer dans une languette 33 de la partie inférieure 11. Les languettes sont terminées par des lèvres 34 qui s'appuient sur l'isolant du câble (fig. 5). Le conducteur dérivé 35 est placé dans un logement 36 ménagé dans la mâchoire fixe 13 et serré par une vis 37 portant une tête 38 protégée par un bouchon isolant 39. L'étanchéité du conducteur dérivé 35 est assurée par un capuchon perforé 41, la lèvre 42 sur le bord de la perforation s'appuyant sur l'isolant du conducteur.The tightness of the housing on the cable 27 is ensured by tongues 31, 32 of the upper part which are nested in a tongue 33 of the lower part 11. The tongues are terminated by lips 34 which rest on the cable insulator (fig. 5). The derivative conductor 35 is placed in a housing 36 formed in the fixed jaw 13 and tightened by a screw 37 carrying a head 38 protected by an insulating plug 39. The sealing of the derivative conductor 35 is ensured by a perforated cap 41, the lip 42 on the edge of the perforation resting on the conductor insulation.

Le boîtier est réalisé en matière plastique isolante par exemple en polyamide ou en PVC. Les pièces métalliques pour différentes raisons d'ordre mécanique et électrique sont réalisées dans un matériau ayant de bonnes aptitudes électriques et mécaniques par exemple en alliage d'aluminium auquel on fera subir un traitement thermo-chimique pour lui conférer une plus grande dureté mécanique. L'originalité du boîtier réside dans le système d'étanchéité autour du câble principal quelle que soit sa section. La forme arrondie et en cloison double des languettes d'étanchéité sur chacune des parties convient à différentes sections de câbles par exemple entre 16 et 70 mm2.The housing is made of insulating plastic, for example polyamide or PVC. The metal parts for different mechanical and electrical reasons are made of a material having good electrical and mechanical properties, for example aluminum alloy which will be subjected to a thermochemical treatment to give it greater mechanical hardness. The originality of the case lies in the sealing system around the main cable regardless of its section. The rounded, double-walled shape of the sealing tabs on each of the parts is suitable for different cable sections, for example between 16 and 70 mm 2 .

Les bouchons isolants recouvrant les têtes de vis permettant de rendre le dispositif de raccordement totalement isolé et de ce fait d'entreprendre une installation sous tension électrique.The insulating plugs covering the screw heads make it possible to make the connection device completely insulated and therefore to undertake an installation under electric voltage.

La mise en place du dispositif de raccordement sur un câble s'effectue de la façon suivante :The installation of the connection device on a cable is carried out as follows:

Le conducteur dérivé 35 étant installé dans son logement et serré, le câble principal 27 est introduit dans le demi-boîtier supérieur 12, le demi-boîtier inférieur 11 est ensuite introduit dans le demi-boîtier supérieur 12, les deux mâchoires 13 et 15 sont guidées par les deux demi-boîtiers. Une pression exercée sur les deux demi-boîtiers réalise l'encliquetage des deux mâchoires 13 et 15 par leurs crans 23, 24 grâce au fléchissement des bras 21, 22 jusqu'à la mise en butée des dents de perforation 14, 16 sur l'isolant du câble principal.The branch conductor 35 being installed in its housing and tightened, the main cable 27 is introduced into the upper half-case 12, the lower half-case 11 is then introduced into the upper half-case 12, the two jaws 13 and 15 are guided by the two half-housings. A pressure exerted on the two half-housings engages the two jaws 13 and 15 by their notches 23, 24 thanks to the flexing of the arms 21, 22 until the abutment teeth 14, 16 are brought into abutment on the main cable insulator.

Sous la poussée de la vis 17, les dents de perforation transpercent l'isolant du câble pour venir en contact avec les brins du câble.Under the thrust of screw 17, the perforation teeth pierce the cable insulation to come into contact with the strands of the cable.

La course de serrage est constante grâce aux butées 29, 30 quelle que soit la section du câble et la valeur du couple de serrage. Ceci réduit le risque de détérioration des brins du câble.The tightening stroke is constant thanks to the stops 29, 30 regardless of the cable section and the value of the tightening torque. This reduces the risk of damage to the cable strands.

La forme arrondie et en double cloison des lèvres du boîtier sous l'effet de la poussée transmise par la vis, exerce une pression sur l'isolant du câble réalisant ainsi l'étanchéité.The rounded shape and double partition of the lips of the housing under the effect of the thrust transmitted by the screw, exerts pressure on the insulation of the cable thus achieving sealing.

Les crantages 23, 24 des mâchoires 13 et 15 permettent de pallier les différences de section des conducteurs.The notches 23, 24 of the jaws 13 and 15 make it possible to compensate for the differences in cross section of the conductors.

Les figures 6 et 7 représentent deux variantes de dispositif de raccordement de câble à un conducteur dérivé dans le cas d'un câble à trois conducteurs séparés 41, 42, 43 isolés chacun par un isolant 28, étant entendu qu'un tel dispositif peut être utilisé pour plus de conducteurs. Un dispositif de raccordement est placé sur chaque conducteur séparé. Le conducteur dérivé est placé dans un logement 46 ménagé à l'intérieur de la denture mobile 16.Figures 6 and 7 show two variants of cable connection device to a branched conductor in the case of a cable with three separate conductors 41, 42, 43 each insulated by an insulator 28, it being understood that such a device can be used for more drivers. A connection device is placed on each separate conductor. The derivative conductor is placed in a housing 46 formed inside the movable teeth 16.

Le serrage du conducteur dérivé 35 est obtenu par une vis 47 placée à l'intérieur de la vis de serrage du câble principal 17 qui est réalisée sous la forme de cylindre creux, ou par une vis 47 fixée sur la denture mobile 16.The clamping of the derivative conductor 35 is obtained by a screw 47 placed inside the clamping screw of the main cable 17 which is produced in the form of a hollow cylinder, or by a screw 47 fixed on the movable teeth 16.

Dans le cas de la figure 6 la position des pattes d'encliquetage 23, 24 est inversée par rapport au cas des figures 3 à 5 et 7.In the case of FIG. 6, the position of the latching lugs 23, 24 is reversed compared to the case of FIGS. 3 to 5 and 7.

La mise en œuvre de l'invention permet d'obtenir un dispositif de raccordement de câble électrique entièrement isolé pour le travail sous tension électrique et étanche à l'eau, avec un système d'encliquetage facilitant son montage et permettant son utilisation pour une grande gamme de câbles de sections différentes, et avec perforation d'isolant à valeur constante par limitation du déplacement de la mâchoire mobile.The implementation of the invention makes it possible to obtain a fully insulated electric cable connection device for working under electric voltage and waterproof, with a snap-in system facilitating its assembly and allowing its use for a large range of cables of different sections, and with insulation perforation at constant value by limiting the movement of the movable jaw.
