Abstract

The U-clamp 2 equipped with its clamping screw 20 is provided so as to slide in relation to the base 1 which includes a sole-plate 10 having two sets of teeth 11. When the U-clamp 2 is in the retracted position, the end of the conductor to be connected can be easily applied against the sole-plate 10, while the axial movement of this same U-clamp performs the axial engagement of the aforementioned end.

Description

La présente invention a trait aux connecteurs éLectriques destinés à assurer le branchement des câbles d'alimentation dans Les boites de jonction et autres appareillages, et elLe concerne plus particuLiere- ment les connecteurs qui sont agencés de façon à ce que la liaison soit effectuée par perforation de La gaine isolante usuelle des conducteurs, en évitant de La sorte L'opération préalabLe de dénudage. The present invention relates to electrical connectors intended to ensure the connection of power cables in junction boxes and other equipment, and it relates more particularly to connectors which are arranged so that the connection is effected by perforation of the usual insulating sheath of the conductors, thereby avoiding the prior stripping operation.

On sait que les connecteurs de ce type comprennent généralement un étrier qui est propre à recevoir axialement L'extrémité du cabLe éiec- trique isolé à raccorder. Cet trier est équipé d'une vis de serrage à l'opposé de laqueLle la paroi interne présente une surface dentée, de façon à ce que L'application à force du câble contre ladite surface sous
L'effet de la vis précitée provoque la perforation de La gaine isolante et l'ancrage des dents dans L'âme métallique du conducteur ou câble.It is known that connectors of this type generally comprise a bracket which is suitable for receiving axially the end of the insulated electrical cabinet to be connected. This sorter is equipped with a clamping screw opposite the lacquer. The internal wall has a toothed surface, so that the force application of the cable against said surface under
The effect of the aforementioned screw causes the perforation of the insulating sheath and the anchoring of the teeth in the metallic core of the conductor or cable.

Ce système donne pleine satisfaction sur le plan de la qualité de
La connexion électrique obtenue ; par contre sa mise en oeuvre pratique se révèle délicate Lorsque Le branchement à effectuer concerne des câbles multiconducteurs de relativement gros diamètre. En pareil cas en effet, la rigidité axiale des conducteurs élémentaires gêne la mise en place successive de ceux-ci à l'intérieur de chacun des étriers du dispositif de raccordement.This system gives full satisfaction in terms of the quality of
The electrical connection obtained; on the other hand, its practical implementation proves to be difficult when the connection to be made relates to relatively large diameter multiconductor cables. In such a case, in fact, the axial rigidity of the elementary conductors hinders the successive positioning of these inside each of the stirrups of the connection device.

C'est à cet inconvénient qu'entend notamment remédier la présente invention, Laquelle consiste principalement à dissocier l'étrier muni de sa vis de serrage et La surface dentée, afin que Ledit étrier soit susceptible de coulisser par rapport à Ladite surface en vue de faciliter. It is to this drawback that the present invention intends to remedy in particular, which mainly consists in dissociating the stirrup provided with its clamping screw and the toothed surface, so that said stirrup is capable of sliding relative to said surface in order to facilitate.

L'engagement du conducteur électrique à brancher.The commitment of the electrical conductor to connect.

Le dessin annexé, donné à 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 vue en perspective montrant un connecteur à perforation d'isolant établi conformément à l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it has and the advantages which it is likely to provide.
Fig. 1 is a perspective view showing an insulation piercing connector established in accordance with the invention.

Fig. 2 est une coupe Longitudinale iLLustrant un mode de mise en oeuvre de L'invention pour la réalisation d'une boite de jonction à fusibles. Fig. 2 is a longitudinal section illustrating an embodiment of the invention for producing a fuse junction box.

Fig. 3 est une vue en plan à plus petite échelle représentant
L'intérieur de la boite envisagée
Le connecteur suivant fig. 1 comprend essentiellement une embase 1 à section en forme de U et un étrier 2 engagé à coulissement longitudinal sur Ladite embase 1.Fig. 3 is a plan view on a smaller scale representing
The interior of the box
The following connector fig. 1 essentially comprises a base 1 with a U-shaped section and a stirrup 2 engaged in longitudinal sliding on said base 1.

L'embase 1, qu'on peut supposer etre réalisée en aluminium, en cui vre ou en un alliage à base d'aluminium ou de cuivre, se prolonge vers l'avant sous la forme d'une semelle longitudinale 10 pourvue de deux rangées parallèles de dents il tournées vers Le haut. A L'opposé de cette semelle 10, l'embase 1 est solidaire d'un dos oblique 12 lui-même pro longé par une plaquette verticale 13, découpée et conformée pour définir deux mâchoires 14 réunies par un anneau élastique 15. The base 1, which can be assumed to be made of aluminum, copper or an alloy based on aluminum or copper, extends forward in the form of a longitudinal sole 10 provided with two rows teeth parallel there facing upwards. Opposite this sole 10, the base 1 is secured to an oblique back 12 itself extended by a vertical plate 13, cut and shaped to define two jaws 14 joined by an elastic ring 15.

La partie inférieure de L'étrier 2 est profilée de façon à être guidée à jeu réduit contre L'embase 1 et la semelle 10. Sa paroi supérieure est taraudée pour recevoir une vis de serrage 20, préférabLement du type à limitation du couple, comme représenté en 21. The lower part of the stirrup 2 is profiled so as to be guided with reduced clearance against the base 1 and the sole 10. Its upper wall is tapped to receive a clamping screw 20, preferably of the type with torque limitation, as shown in 21.

En fig. 2, on a supposé que le connecteur suivant fig. 1 était destiné au branchement d'une cartouche fusible 3. Le dos 12 prend appui contre un bossage 40 prévu en saillie sur le fond 4 d'une boîte de jonction, et est fixé en place de toute manière appropriée, par exemple à l'aide de vis telles que 41. In fig. 2, it has been assumed that the following connector in fig. 1 was intended for the connection of a fuse cartridge 3. The back 12 bears against a boss 40 provided projecting from the bottom 4 of a junction box, and is fixed in place in any suitable manner, for example at the using screws such as 41.

Pour opérer le banchement du conducteur d'alimentation 5 sur
L'embase 1, on commence par appliquer son extrémité contre la semelle 10 ; cette mise en place ne présente aucune difficulté du fait que
L'étrier 2 se trouve à la position reculée représentée en 2' et que quel le que soit leur rigidité dans le sens axial, les conducteurs usuels sont toujours susceptibles d'être aisément fléchis dans La sens latéral.To connect the supply conductor 5 to
The base 1, we start by applying its end against the sole 10; this installation does not present any difficulty since
The stirrup 2 is in the remote position shown in 2 'and that whatever their rigidity in the axial direction, the usual conductors are always likely to be easily bent in the lateral direction.

Une fois l'extrémité du conducteur 5 ainsi disposée au-dessus de la semelle 10, l'étrier 2 est déplacé axialement de manière à venir au-dessus de la semelle 10 en chevauchant ainsi l'extrémité précitee ;
La manoeuvre de la vis 20 au serrage jusqu'à rupture de la tête double 21 assure bien l'application à force du conducteur 5 contre la semelle 10 dont les dents 11 viennent perforer la gaine isolante dudit conducteur et s'ancrer contre L'âme métallique de celui-ci.Once the end of the conductor 5 is thus disposed above the sole 10, the stirrup 2 is moved axially so as to come above the sole 10, thus overlapping the abovementioned end;
The operation of the screw 20 when tightened until the double head 21 breaks properly ensures that the conductor 5 is force applied against the sole 10 whose teeth 11 puncture the insulating sheath of said conductor and anchor against the core metallic of it.

Il suffit alors de procéder à la mise en place. d'une cartouche fusible qui peut être insérée entre les mors 14 d'un côté ou de l'autre, comme représenté par les tracés 3 et 3'
Fig. 3 illustre les manoeuvres pour le branchement, à l'aide de connecteurs à perforation d'isolant établis conformément à l'invention, d'un câble 5 à quatre conducteurs pour l'alimentation d'un appareillage quelconque. Les quatre embases 1 avec leur étrier 2 sont fixées paralle- lement les unes aux autres contre le fond 4 de la boite de jonction, comme décrit en référence à fig. 1.It then suffices to proceed with the installation. a fuse cartridge which can be inserted between the jaws 14 on one side or the other, as shown by the lines 3 and 3 '
Fig. 3 illustrates the maneuvers for the connection, using insulation piercing connectors established in accordance with the invention, of a cable 5 with four conductors for supplying any equipment. The four bases 1 with their stirrup 2 are fixed parallel to each other against the bottom 4 of the junction box, as described with reference to FIG. 1.

Pour le connecteur le plus à gauche en fig. 3, le branchement n'est pas encore effectué. Comme indiqué ci-dessus, L'opérateur doit déformer
Le conducteur 50 envisagé pour l'amener au-dessus de la semelle 10,
Laquelle est complètement découverte puisque son étrier 2 se trouve à La position reculée. Cette première manoeuvre a été supposée effectuée pour ce qui est du deuxième connecteur à partir de la gauche et L'on comprend qu'il suffit à L'opérateur de faire coulisser axialement L'étrier 2 pour l'amener à la position avancée ilLustrée pour ce qui concerne l-e trai sième connecteur 50, et de procéder au serrage de la vis 20 jusqu'à rupture de la tête double 21. Le branchement est complété par mise en place des cartouches fusibles 3, comme illustré pour ce qui est du connecteur le plus à droite en fig. 3.Préalablement à La mise en place du capot de fermeture 6, le câble 5 est fixé à L'entrée de La boite de jonction, moyennant manoeuvre des vis 70 qui assurent la fixation du collier usuel 7.For the leftmost connector in fig. 3, the connection has not yet been made. As indicated above, The operator must deform
The conductor 50 envisaged to bring it above the sole 10,
Which is completely uncovered since its stirrup 2 is in the remote position. This first maneuver was supposed to have been carried out with regard to the second connector from the left and it is understood that it suffices for the operator to slide the caliper 2 axially to bring it to the advanced position ilLustrée pour as regards the third connector 50, and to tighten the screw 20 until the double head 21 breaks. The connection is completed by fitting the fuse cartridges 3, as illustrated with regard to the connector more to the right in fig. 3. Prior to the installation of the closure cover 6, the cable 5 is fixed to the inlet of the junction box, by means of the operation of the screws 70 which secure the usual collar 7.

On comprend sans peine que queLle que soit la rigidité axiale des conducteurs 50, Leur mise en place par flexion latérale au-dessus des semelles 10 ne présente aucune difficulté, alors que dans les connecteurs classiques équipés d'un étrier rigidement fixé à l'embase, ce même engagement est beaucoup plus malaisé. On observera qu'en vue de simplifier encore la manoeuvre en ce qui concerne les conducteurs 50 latéraux, on peut avantageusement réaliser des connecteurs dans lesquels la semelle 2 et L'embase 1 sont orientées obliquement par rapport à l'axe des mâchoires 14, L'angle d'obliquité pouvant varier entre 1 et 300. It is easy to understand that whatever the axial rigidity of the conductors 50, their positioning by lateral bending above the soles 10 presents no difficulty, whereas in conventional connectors equipped with a stirrup rigidly fixed to the base , this same commitment is much more difficult. It will be observed that, in order to further simplify the operation with regard to the lateral conductors 50, it is advantageously possible to produce connectors in which the sole 2 and the base 1 are oriented obliquely relative to the axis of the jaws 14, L obliqueness angle can vary between 1 and 300.

La retenue provisoire des étrier 2 à la position reculée peut être assurée de toute manière appropriée, par exemple par simple friction contre le fond 4. Provisional retention of the stirrups 2 in the retracted position can be ensured in any suitable manner, for example by simple friction against the bottom 4.

IL doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'eLLe ne limite nullement Le domaine de L'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
