Abstract

The moveable head (1), cut out from a flared profile hole (71) which enables it to rock laterally, is applied elastically against the cables (A,a) by means of the spring (60) associated with the clamping screw (6), thus allowing, prior to the penetration of their insulation, the positioning of the said cables by the operator with the aid of one hand only. <IMAGE>

Description

La présente invention a trait aux connecteurs unipolaires destinés au branchement d'une dérivation sur un câble principal d'alimentation élec­trique.The present invention relates to single-pole connectors for connecting a branch to a main power supply cable.

On sait qu'en vue de simplifier les opérations de branchement, on a pro­posé des connecteurs de dérivation qui ne nécessitent pas le dénudage préalable des deux câbles. A cet effet, le dispositif est pourvu de deux jeux de lames qui sont propres, sous l'effet de serrage de deux vis de manoeuvre, à perforer l'isolant pour venir au contact de l'âme métalli­que du câble correspondant. Mais on a proposé d'aller plus loin encore dans le domaine de la simplification de la pose, en remplaçant les deux vis de manoeuvre par une tête mobile unique dont la face tournée en di­rection des lames est creusée de deux dépressions pour prendre appui sur les deux câbles envisagés, ladite tête mobile étant commandée par une seule vis de serrage.We know that in order to simplify the connection operations, branch connectors have been proposed which do not require the prior stripping of the two cables. To this end, the device is provided with two sets of blades which are capable, under the tightening effect of two operating screws, of perforating the insulation to come into contact with the metallic core of the corresponding cable. However, it has been proposed to go even further in the field of simplification of the installation, by replacing the two maneuvering screws with a single movable head whose face turned towards the blades is hollowed out by two depressions to rest on the two cables envisaged, said movable head being controlled by a single clamping screw.

L'expérience a toutefois démontré que la simplification envisagée n'était pas réelle, en ce sens que l'engagement des deux câbles dans le connecteur, puis la manoeuvre de la vis de serrage, constituaient une manoeuvre qui restait délicate même pour un opérateur disposant de ses deux mains, et qui se révèlait totalement impossible à l'aide d'une seule main.However, experience has shown that the simplification envisaged was not real, in the sense that the engagement of the two cables in the connector, then the operation of the tightening screw, constituted an operation which remained delicate even for an operator having with both hands, and which was completely impossible with one hand.

C'est à cet inconvénient qu'entend principalement remédier la présente invention, laquelle a pour objet le connecteur unipolaire défini à la revendication 1. En fait l'invention consiste à associer à la tête mobile, susceptible de basculer latéralement dans un plan transversal aux lames de perforation renfermées par le corps isolant, des moyens élastiques qui tendent à la rappeler en permanence en appui contre la face en vis-à-vis du corps isolant.It is to this drawback that the present invention mainly intends to remedy, which relates to the single-pole connector defined in claim 1. In fact the invention consists in associating with the movable head, capable of tilting laterally in a plane transverse to perforation blades enclosed by the insulating body, elastic means which tend to return it permanently by pressing against the face facing the insulating body.

On conçoit dans ces conditions que le montage du connecteur sur le câble principal et sur le câble de dérivation ne pose plus aucun problème et est susceptible d'être réalisé sans difficulté même pour un monteur ne disposant pratiquement que d'une seule main, comme le cas arrive dans les travaux sur lignes aériennes.It is therefore understandable that mounting the connector on the main cable and on the branch cable no longer poses any problem and is capable of being carried out without difficulty even for an assembler having practically only one hand, such as the case occurs in works on overhead lines.

Le dessin annexé donné à simple titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une coupe axiale d'un connecteur suivant l'invention, représenté préalablement à la manoeuvre de la vis de serrage.
  • Fig. 2 montre en perspective, à l'état séparé, les différentes pièces constitutives du connecteur suivant fig. 1.
  • Fig. 3, 4 et 5 illustrent la pose de ce connecteur.
  • Fig. 6 est une coupe verticale représentant la perforation de l'isolant une fois que la vis de serrage a été complètement manoeu­vrée.
The appended drawing, given by way of example only, will allow a better understanding of the invention, the characteristics which it presents and the advantages it is likely to provide:
  • Fig. 1 is an axial section of a connector according to the invention, shown prior to the operation of the clamping screw.
  • Fig. 2 shows in perspective, in a separate state, the various component parts of the connector according to FIG. 1.
  • Fig. 3, 4 and 5 illustrate the installation of this connector.
  • Fig. 6 is a vertical section showing the perforation of the insulator once the clamping screw has been completely maneuvered.

Le connecteur représenté en fig. 1 comprend un corps isolant 1 qui, comme montré en fig. 2, se présente sous la forme d'un cadre à profil rectangulaire, fermé vers le haut par une paroi plane 10, solidaire d'une cheminée axiale creuse 11. On observera que la paroi 10 est décou­pée de deux jeux d'ouvertures 12 et 13, la surface de la section des premières étant supérieure à celle des secondes.The connector shown in fig. 1 comprises an insulating body 1 which, as shown in FIG. 2, is in the form of a rectangular profile frame, closed upwards by a flat wall 10, secured to a hollow axial chimney 11. It will be observed that the wall 10 is cut from two sets of openings 12 and 13, the surface of the section of the former being greater than that of the latter.

Dans ce corps 1 est destiné à venir se loger un joint 2 en une matière synthétique souple. Ce joint 2 comporte une ouverture centrale 20 et deux jeux de deux bossages 21 et 22 aptes à venir s'engager à l'inté­rieur des ouvertures 12 et 13 du corps 1. Il convient de noter que la partie supérieure des bossages 21 et 22 est ouverte à son sommet et présente un profil cintré à concavité ouverte vers le haut ; dans ces bossages sont engagées les lames 30, respectivement 31, d'un perforateur métallique 3 découpé en son centre d'une ouverture 32, et propre à être introduit à l'intérieur du joint 2.In this body 1 is intended to accommodate a seal 2 made of a flexible synthetic material. This seal 2 has a central opening 20 and two sets of two bosses 21 and 22 capable of coming to engage inside the openings 12 and 13 of the body 1. It should be noted that the upper part of the bosses 21 and 22 is open at its top and has a curved profile with a concavity open upwards; in these bosses are engaged the blades 30, respectively 31, of a metal perforator 3 cut in its center of an opening 32, and suitable for being inserted inside the joint 2.

Le joint 2 et le perforateur 3 sont maintenus en place par une plaquette d'appui 4 dans la partie centrale de laquelle est prévu un bossage tubulaire 40 propre à s'engager de manière étanche dans les ouvertures 32 et 20 et à l'intérieur de la base de la cheminée 11. Cette plaquette 4 est maintenue en place par un écrou 5 percé d'un taraudage 50 agencé de manière à coopérer avec la base d'une vis de serrage 6 (fig. 1) associée à un ressort 60 à profil conique et à une rondelle d'appui 61.The seal 2 and the perforator 3 are held in place by a support plate 4 in the central part of which is provided a tubular boss 40 capable of sealingly engaging in the openings 32 and 20 and inside the base of the chimney 11. This plate 4 is held in place by a nut 5 pierced by a thread 50 arranged so as to cooperate with the base of a clamping screw 6 (fig. 1) associated with a spring 60 to conical profile and a support washer 61.

A l'ensemble 1-2-3-4-5 ainsi constitué est associée une tête mobile ou mâchoire 7 pourvue d'oreilles latérales 70 et découpée d'une lumière 71. On observera (voir fig. 1) que cette lumière 71 présente en section verticale un profil évasé en forme de trapèze dont la petite base com­porte une longueur légèrement supérieure au côté de la cheminée 11. On notera par ailleurs que la face inférieure de la tête 7 est creusée de deux dépressions 72 à profil en arc de cercle.With the assembly 1-2-3-4-5 thus formed is associated a movable head or jaw 7 provided with lateral ears 70 and cut out with a light 71. It will be observed (see fig. 1) that this light 71 has in vertical section a flared profile in the shape of a trapezium whose small base has a length slightly greater than the side of the chimney 11. It will also be noted that the underside of the head 7 is hollowed out by two depressions 72 with a circular arc profile .

Le corps 1 est complété par un capot inférieur 8 dont la partie centrale comporte un puits 80 qui est destiné à former cache pour l'extrémité inférieure de la vis 6 et dont le bord supérieur ouvert est adapté à venir s'encliqueter élastiquement dans une cavité ménagée dans la face inférieure de l'écrou 5. Ce capot 8 présente deux dépressions 81 orien­tées suivant l'axe des oreilles latérales 70 de la tête mobile 7, afin de former appuis ergonomiques pour les doigts de l'utilisateur.The body 1 is completed by a lower cover 8, the central part of which comprises a well 80 which is intended to form a cover for the lower end of the screw 6 and the open upper edge of which is adapted to snap elastically into a cavity formed in the underside of the nut 5. This cover 8 has two depressions 81 oriented along the axis of the lateral ears 70 of the movable head 7, in order to form ergonomic supports for the fingers of the user.

Pour exposer le mode de montage d'un tel connecteur, on se reportera aux fig. 3, 4 et 5.To explain the method of mounting such a connector, reference is made to FIGS. 3, 4 and 5.

En fig. 3, l'extrémité inférieure de la vis 6 est juste engagée dans le taraudage 50 de l'écrou 5, de telle sorte que le ressort 60 n'est pas comprimé. Néanmoins, ce ressort 60 exerce une pression élastique non négligeable sur la tête 7 qui est ainsi maintenue appliquée contre les bossages 21 et 22 du joint 2. L'opérateur peut ainsi exercer sur l'une des oreilles 70 (flèche F1) une pression dirigée vers le corps 1 ; par suite de la conformation de la lumière 71, cette tête 7 bascule, de telle sorte que le câble principal A est susceptible, à l'aide d'une seule main, d'être introduit latératlement entre la dépression 72 de ladite tête et le jeu de bossages 21. Dès que la pression sur l'oreille 70 envisagée est relâchée, la tête 7 revient à sa position initiale sous l'effet du ressort 60, si bien que le dispositif est dès lors supporté par le câble principal A, sans que l'opérateur ait à intervenir manuel­lement.In fig. 3, the lower end of the screw 6 is just engaged in the internal thread 50 of the nut 5, so that the spring 60 is not compressed. However, this spring 60 exerts a significant elastic pressure on the head 7 which is thus kept applied against the bosses 21 and 22 of the seal 2. The operator can thus exert on one of the ears 70 (arrow F1) a directed pressure towards body 1; as a result of the conformation of the light 71, this head 7 rocks, so that the main cable A is capable, with the help of one hand, of being introduced laterally between the depression 72 of said head and the set of bosses 21. As soon as the pressure on the ear 70 envisaged is released, the head 7 returns to its initial position under the effect of the spring 60, so that the device is therefore supported by the main cable A, without that the operator has to intervene manually.

Le câble de la dérivation a peut être assujetti au dispositif de la même manière, c'est-à-dire (cf. fig. 4) en exerçant une pression (flèche F2) sur l'oreille 70 opposée. L'intervention ne soulève donc aucune diffi­culté, étant observé que la fixation de ce câble a est également suscep­tible d'être effectuée préalablement au branchement du câble principal A.The bypass cable a can be secured to the device in the same way, that is to say (see fig. 4) by exerting pressure (arrow F2) on the opposite ear 70. The intervention therefore does not raise any difficulty, it being observed that the fixing of this cable a is also likely to be carried out prior to the connection of the main cable. AT.

En tout état de cause, le dispositif se présente finalement à la manière illustrée en fig. 5 ; la tête 7 repose élastiquement sur les deux câbles A et a qui sont eux-mêmes appliqués contre les bossages 22. Il suffit alors de procéder au serrage de la vis 6, avantageusement pourvue d'une tête de manoeuvre 62 du type à limitation du couple par rupture. Cette rupture intervient en fin de serrage, c'est-à-dire lorsque le ressort 61 est complètement comprimé et que la base de cette tête 62 est au contact de la paroi supérieure de la tête 7. Par suite de l'effort axial ainsi exercé, les bossages 21 et 22 du joint 2 se sont écrasés en découvrant les deux jeux de lames 30 et 31 dont les bords acérés viennent percer l'isolant des câbles A et a et s'ancrer dans l'âme métallique de ceux-ci en établissant de la sorte la connexion (voir fig. 6).In any event, the device is finally presented in the manner illustrated in FIG. 5; the head 7 rests elastically on the two cables A and a which are themselves applied against the bosses 22. It then suffices to tighten the screw 6, advantageously provided with an operating head 62 of the type with torque limitation by rupture. This rupture occurs at the end of tightening, that is to say when the spring 61 is completely compressed and the base of this head 62 is in contact with the upper wall of the head 7. As a result of the axial force thus exerted, the bosses 21 and 22 of the joint 2 are crushed by revealing the two sets of blades 30 and 31 whose sharp edges pierce the insulation of the cables A and a and anchor in the metallic core of these thus establishing the connection (see fig. 6).

L'installation du connecteur est complétée en assujettissant sur l'ex­trémité du câble de dérivation a un capuchon borgne 14 (voir fig. 2 et 6) réuni par un bras souple 15 à un bouton latéral 16 du corps 1, ledit capuchon étant jusqu'alors retenu en attente contre le capot 8 à l'aide d'une patte de fixation 82.The installation of the connector is completed by subjecting the end of the branch cable has a blind end cap 14 (see fig. 2 and 6) joined by a flexible arm 15 to a side button 16 of the body 1, said cap being up then retained on hold against the cover 8 using a fixing lug 82.

L'étanchéité de la connexion est totale. Les opérations de branchement sont simplifiées au maximum et peuvent à la limite être effectuées d'une seule main ; le branchement est susceptible d'intervenir sans danger alors que le câble principal A est sous tension.The tightness of the connection is complete. The connection operations are simplified as much as possible and can ultimately be carried out with one hand; the connection is likely to occur without danger while the main cable A is energized.
