Description

L'invention a trait à un jeu de connecteurs dont chacun est apte à raccorder un conducteur de câble à un couteau appartenant à un fusible ou à un barreau conducteur. L'invention a également trait à un procédé de fabrication d'un tel connecteur.The invention relates to a set of connectors each of which is capable of connecting a cable conductor to a knife belonging to a fuse or to a conducting bar. The invention also relates to a method of manufacturing such a connector.

Il est connu d'utiliser des connecteurs pour le raccordement de câbles amont et aval par l'intermédiaire d'un fusible ou d'un barreau conducteur dont les couteaux sont respectivement engagés dans des mâchoires prévues sur ces connecteurs. Il est connu, par exemple de FR-A-1 359 746 , FR-A-2 817 400 , FR-A-2 859 575 et FR-A-2 848 732 , de définir dans un connecteur un volume ou cage de réception de l'extrémité d'un câble à raccorder, alors qu'une vis de serrage est arrangée pour presser cette extrémité contre une denture de perforation de la gaine isolante. Dans ces connecteurs, les mâchoires sont définies pour recevoir chacune un couteau appartenant au fusible ou au barreau conducteur associé. Un connecteur de raccordement peut être intégré dans divers circuits électriques, au point que l'intensité qui le traverse peut être très variable, par exemple comprise entre 10 et 100 ampères (A). Les connecteurs actuels sont parfois différenciés en fonction de l'intensité maximale du courant censé les traverser, cette intensité étant plus souvent dénommée « intensité nominale ». Cette différenciation impose de prévoir des connecteurs avec des constructions différentes, ce qui majore le prix de revient d'un jeu de connecteurs susceptibles d'être utilisés dans des circuits où l'intensité du courant peut varier. Par ailleurs, en l'absence d'une telle différenciation des connecteurs, certains connecteurs sont surdimensionnés lorsqu'ils sont montés dans des circuits de faible ampérage ou risquent d'être insuffisamment dimensionnés lorsqu'ils sont montés dans des circuits de fort ampérage.It is known to use connectors for connecting upstream and downstream cables via a fuse or a conductive bar whose knives are respectively engaged in the jaws provided on these connectors. It is known, for example from FR-A-1,359,746 , FR-A-2,817,400 , FR-A-2,859,575 and FR-A-2,848,732 defining in a connector a receiving volume or cage of the end of a cable to be connected, while a clamping screw is arranged to press this end against a perforation toothing of the insulating sheath. In these connectors, the jaws are defined to each receive a knife belonging to the fuse or the associated driver bar. A connection connector can be integrated in various electrical circuits, to the point that the intensity that passes through it can be very variable, for example between 10 and 100 amperes (A). The current connectors are sometimes differentiated according to the maximum intensity of the current supposed to cross them, this intensity being more often called "nominal intensity". This differentiation requires the provision of connectors with different constructions, which increases the cost of a set of connectors that can be used in circuits where the intensity of the current can vary. Moreover, in the absence of such a differentiation of the connectors, some connectors are oversized when they are mounted in circuits of low amperage or may be insufficiently dimensioned when mounted in circuits of high amperage.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau jeu de connecteurs dont les différents connecteurs peuvent être choisis en fonction de l'ampérage prévu pour le circuit dans lequel ils sont destinés à être intégrés.It is these drawbacks that the invention intends to remedy more particularly by proposing a new set of connectors whose different connectors can be chosen according to the amperage provided for the circuit in which they are intended to be integrated.

A cet effet, l'invention concerne un jeu de connecteurs dont chaque connecteur est apte à raccorder un conducteur de câble à un couteau de fusible ou de barreau conducteur, chaque connecteur comprenant une cage de réception d'une extrémité de conducteur et une mâchoire de réception d'un couteau. La mâchoire de chaque connecteur est formée par une plaque de matériau électriquement conducteur, qui constitue une des branches de cette mâchoire, et une lame élastiquement déformable, qui constitue l'autre branche de cette mâchoire, alors que les propriétés de conduction électrique de la plaque sont variables d'un conducteur à l'autre, en fonction de l'intensité nominale du courant traversant ce connecteur.For this purpose, the invention relates to a set of connectors, each connector of which is capable of connecting a cable conductor to a fuse or conductor bar, each connector comprising a receiving cage of a conductor end and a jaw of receiving a knife. The jaw of each connector is formed by a plate of electrically conductive material, which constitutes one of the branches of this jaw, and an elastically deformable blade, which constitutes the other branch of this jaw, while the electrical conduction properties of the plate are variable from one conductor to another, depending on the rated current current flowing through this connector.

Grâce à l'invention, les différents connecteurs d'un jeu de connecteurs peuvent être facilement adaptés à leur intensité nominale, par changement de la plaque formant l'une des branches de la mâchoire, les autres parties constitutives des différents connecteurs du jeu de connecteur pouvant être identiques d'un type de connecteur à l'autre.Thanks to the invention, the different connectors of a set of connectors can be easily adapted to their nominal intensity, by changing the plate forming one of the branches of the jaw, the other constituent parts of the various connectors of the connector set can be identical from one type of connector to another.

Selon des aspects avantageux mais non obligatoires de l'invention, un jeu de connecteurs peut incorporer une ou plusieurs des caractéristiques suivantes :

  • L'épaisseur moyenne de la plaque est variable d'un connecteur à l'autre, en fonction de l'intensité nominale précitée. Dans ce cas, cette épaisseur est avantageusement comprise entre 0,5 et 3,5 mm pour une intensité nominale comprise entre 10 et 100 A. En particulier, cette épaisseur moyenne peut être égale à 2 mm pour une intensité nominale de 60 A et 3 mm pour une densité nominale de 90 A.
  • Le matériau constitutif de la plaque est variable d'un connecteur à l'autre, en fonction de l'intensité nominale précitée.
  • Dans un jeu de connecteurs dont l'un est un connecteur de neutre, les propriétés de conduction électrique de la plaque du connecteur de neutre sont différentes des propriétés de conductions électriques des plaques des autres connecteurs. En particulier, l'épaisseur et/ou le matériau constitutif de la plaque du connecteur de neutre est/sont différente(s) de l'épaisseur et/ou du matériau constitutifs de la plaque des autres connecteurs.
  • L'épaisseur de la plaque est, pour certains connecteurs au moins, plus importante dans certaines zones de cette plaque que dans le reste de cette plaque.
  • Selon un premier mode de réalisation de l'invention, la plaque et la lame de chaque connecteur forment également ensemble la cage de réception d'une extrémité de conducteur.
  • Selon un deuxième mode de réalisation de l'invention, la plaque et la lame sont rapportées sur cette cage. Dans ce cas, la plaque peut être pourvue d'une partie dentée reçue à l'intérieur de la cage et destinée à perforer une gaine isolante d'une extrémité de conducteur.
According to advantageous but non-mandatory aspects of the invention, a set of connectors may incorporate one or more of the following features:
  • The average thickness of the plate varies from one connector to another, depending on the intensity aforementioned nominal. In this case, this thickness is advantageously between 0.5 and 3.5 mm for a nominal intensity of between 10 and 100 A. In particular, this average thickness may be equal to 2 mm for a nominal intensity of 60 A and 3 mm for a nominal density of 90 A.
  • The material constituting the plate is variable from one connector to the other, depending on the aforementioned nominal intensity.
  • In a set of connectors, one of which is a neutral connector, the electrical conduction properties of the neutral connector plate are different from the electrical conduction properties of the plates of the other connectors. In particular, the thickness and / or the constituent material of the plate of the neutral connector is / are different (s) from the thickness and / or material constituting the plate of the other connectors.
  • The thickness of the plate is, for some connectors at least, greater in certain areas of this plate than in the rest of this plate.
  • According to a first embodiment of the invention, the plate and the blade of each connector also together form the receiving cage of a conductor end.
  • According to a second embodiment of the invention, the plate and the blade are attached to this cage. In this case, the plate may be provided with a toothed portion received inside the cage and intended to perforate an insulating sheath of a conductor end.

L'invention concerne également un procédé de fabrication d'un connecteur du type des connecteurs mentionnés ci-dessus. Ce procédé est caractérisé en ce qu'il comprend des étapes consistant à :

  • sélectionner, en fonction de l'intensité nominale du connecteur, une plaque électriquement conductrice et
  • intégrer cette plaque à ce connecteur pour constituer l'une des branches de la mâchoire du connecteur.

  • the figure 10 is a view similar to the figure 9 and shows another connector belonging to the same set of connectors.

Le coffret 1 représenté aux figures 1 et 2 est prévu pour le raccordement de quatre conducteurs A1 à A4 appartenant à un câble amont A avec quatre conducteurs B1 à B4 appartenant à un câble aval B, les conducteurs A1 et B1 véhiculant le neutre, alors les conducteurs A2 à A4 et B2 à B4 véhiculent les trois phases d'un courant électrique triphasé.

Le barreau 2 et les fusibles 3, 3' et 3" sont chacun pourvus de couteaux 21 et 22, respectivement 31 et 32, destinés à être chacun engagés dans une mâchoire formée par un connecteur amont ou aval.The box 1 represented in figures 1 and 2 is provided for the connection of four conductors A 1 to A 4 belonging to an upstream cable A with four conductors B 1 to B 4 belonging to a downstream cable B, the conductors A 1 and B 1 conveying the neutral, then the conductors A 2 A 4 and B 2 to B 4 convey the three phases of a three-phase electric current. A conductor bar 2 is provided to ensure the continuity of the circuit of the conductors A 1 and B 1 , while three fuses 3, 3 'and 3 "are provided to ensure the continuity of the phase conductors circuit The bar 2 and the fuses 3, 3 'and 3 "are each provided with knives 21 and 22, respectively 31 and 32, each intended to be engaged in a jaw formed by an upstream or downstream connector.

Les connecteurs 10 utilisés pour raccorder les extrémités des conducteurs au barreau 2 ou aux fusibles 3, 3' et 3" sont montés sur deux rangées parallèles entre elles. Plus précisément, quatre connecteurs amont 10 sont disposés selon une première rangée R1 située en partie haute du coffret 1 parallèlement à sa face supérieure 101, alors que quatre connecteurs aval 10 sont disposés selon une seconde rangée R2 parallèle à la première et située en dessous de celle-ci.The connectors used to connect the ends of the conductors to the bar 2 or to the fuses 3, 3 'and 3 "are mounted in two rows parallel to each other, more precisely four upstream connectors 10 are arranged in a first row R 1 located in part. high of the cabinet 1 parallel to its upper face 101, while four downstream connectors 10 are arranged in a second row R 2 parallel to the first and located below it.

Les connecteurs utilisés dans les rangées R1 et R2 sont similaires. Chaque connecteur 10 comporte des pièces métalliques visibles aux figures 4 à 8 et qui comprennent une plaque coudée 11 comprenant deux parties 111 et 112 globalement parallèles reliées par une zone 113 dans laquelle sont prévus deux coudes 114 et 115. Une autre zone coudée 116 relie la partie plane 112 à une partie 117 dans laquelle une denture 118 est ménagée en rabattant les bords découpés de la partie 117. Cette denture permet de perforer la gaine isolante entourant l'extrémité d'un conducteur.The connectors used in rows R 1 and R 2 are similar. Each connector 10 comprises metal parts visible to Figures 4 to 8 and which comprise a bent plate 11 comprising two generally parallel parts 111 and 112 connected by a zone 113 in which two bends 114 and 115 are provided. Another bent zone 116 connects the flat part 112 to a part 117 in which a toothing 118 is arranged by folding the cut edges of the portion 117. This toothing perforate the insulating sheath surrounding the end of a conductor.

La plaque 11 est réalisée en cuivre. Elle pourrait également être réalisée en aluminium, en laiton, ou dans tout autre alliage électriquement conducteur.The plate 11 is made of copper. It could also be made of aluminum, brass, or any other electrically conductive alloy.

Une lame élastique 12, en acier à ressort ou dans un autre matériau élastique, est rapportée sur la plaque 11 et comprend deux voiles 121 et 122 globalement parallèles reliés par un voile 123 perpendiculaire à ces deux voiles et parallèle à la partie 112 de la plaque 11. Un voile 124 parallèle au voile 123 est relié par une zone de transition inclinée 125 à une partie globalement plane 126.An elastic blade 12 made of spring steel or of another elastic material is attached to the plate 11 and comprises two generally parallel webs 121 and 122 connected by a web 123 perpendicular to these two webs and parallel to the part 112 of the plate 11. A web 124 parallel to the web 123 is connected by an inclined transition zone 125 to a generally flat portion 126.

Le voile 121 est engagé sous la partie 117 de la plaque 11, alors qu'une ouverture 127 est prévue dans la zone courbe de transition entre les voiles 121 et 123, cette ouverture 127 recevant l'extrémité 119 de la partie 117, ce qui permet un verrouillage des parties inférieures respectives de la plaque 11 et de la lame 12 l'une sur l'autre, le voile 121 recouvrant la partie 117.The web 121 is engaged under the part 117 of the plate 11, while an opening 127 is provided in the transition curve zone between the webs 121 and 123, this opening 127 receiving the end 119 of the part 117, which allows a locking of the respective lower portions of the plate 11 and the blade 12 one on the other, the web 121 covering the portion 117.

Le voile 124 de la lame 11 est en appui surfacique sur la partie 112 de la plaque et est immobilisé contre celle-ci par un boulon 13. Ainsi, il est formé une cage 14 délimitée par les parties 112, 117, 123 et 122 des pièces 11 et 12, cette cage 14 étant destinée à recevoir l'extrémité d'un conducteur de câble A1 à B4 ou B1 à B4. Par ailleurs, à partir de la zone 125, la partie 126 de la lame 12 s'étend à distance de la partie 111 de la plaque 11, ces parties 111 et 126 constituant respectivement les branches 151 et 152 d'une mâchoire 15 de réception d'un des couteaux 21, 22, 31 ou 32.The web 124 of the blade 11 is in surface abutment on the part 112 of the plate and is immobilized thereon by a bolt 13. Thus, a cage 14 is formed delimited by the parts 112, 117, 123 and 122 of the plates. parts 11 and 12, this cage 14 being intended to receive the end of a cable conductor A 1 to B 4 or B 1 to B 4 . Furthermore, from the zone 125, the portion 126 of the blade 12 extends away from the portion 111 of the plate 11, these portions 111 and 126 respectively constituting the branches 151 and 152 of a receiving jaw 15 of one of the knives 21, 22, 31 or 32.

Une vis de serrage 16 est montée dans un crevé taraudé 122a ménagé dans le voile 122. En variante, le crevé taraudé 122a peut être remplacé par un insert taraudé fixé dans un orifice traversant le voile 122.A clamping screw 16 is mounted in a threaded puncture 122a formed in the web 122. In a variant, the threaded puncture 122a can be replaced by a threaded insert fixed in an orifice passing through the web 122.

Ainsi, il est possible d'introduire, dans la cage 14 d'un connecteur 10 représenté à la figure 3, l'extrémité E2 du conducteur A2 en déplaçant cette extrémité dans le sens de la flèche F1 aux figures 3 et 4, c'est-à-dire en pénétrant dans le volume intérieur V14 de la cage 14 par le côté C1 de cette cage visible à la figure 5, qui sera considéré dans ce qui suit comme un premier côté de cette cage 14. De la même manière, et comme représenté au bas de la figure 3, il est possible d'introduire l'extrémité E'2 du conducteur B2 dans la cage 14 d'un second connecteur 10 par le côté C2 visible pour le connecteur représenté en partie inférieure de la figure 4 et qui sera considéré dans ce qui suit comme le second côté de la cage 14 du second connecteur. Le mouvement d'introduction de l'extrémité E'2 dans la cage 14 correspondante est représenté par la flèche F2 aux figures 3 et 4. Le côté C2 de la cage 14 n'est pas visible à la figure 5.Thus, it is possible to introduce into the cage 14 a connector 10 represented in FIG. figure 3 , the end E 2 of the conductor A 2 by moving this end in the direction of the arrow F 1 to Figures 3 and 4 , that is to say by penetrating the internal volume V 14 of the cage 14 by the side C 1 of this cage visible at the figure 5 , which will be considered in the following as a first side of this cage 14. In the same way, and as represented at the bottom of the figure 3 it is possible to introduce the end E ' 2 of the conductor B 2 into the cage 14 of a second connector 10 by the side C 2 visible for the connector shown in the lower part of the figure 4 and which will be considered in the following as the second side of the cage 14 of the second connector. The insertion movement of the end E ' 2 in the corresponding cage 14 is represented by the arrow F 2 to Figures 3 and 4 . The C 2 side of the cage 14 is not visible at the figure 5 .

On note X14 l'axe médian de la cage 14 d'un connecteur 10. L'extrémité d'un conducteur de câble introduit dans une telle cage 14 s'étend globalement selon cet axe, quel que soit son côté d'introduction.X 14 is the middle axis of the cage 14 of a connector 10. The end of a cable conductor introduced into such a cage 14 extends generally along this axis, regardless of its insertion side.

On note X15 un axe longitudinal médian de la mâchoire 15, c'est-à-dire un axe selon lequel est orienté un couteau 21 ou 22 du barreau 2 ou un couteau 31 ou 32 d'un des fusibles 3, 3' ou 3" introduit dans cette mâchoire.X 15 is a median longitudinal axis of the jaw 15, that is to say an axis in which is oriented a knife 21 or 22 of the bar 2 or a knife 31 or 32 of a fuse 3, 3 'or 3 "introduced into this jaw.

Comme il ressort plus particulièrement des figures 3 et 4, il est possible de monter deux connecteurs 10 en alignant sensiblement leurs mâchoires 15 respectives de telle sorte que leurs axes X15 respectifs sont confondus mais en retournant l'un des connecteurs 10 par rapport à l'autre, de telle sorte que le côté C1 de la mâchoire 14 de l'un de ces connecteurs fait face à la partie inférieure 103 du coffret 1 par laquelle arrivent les câbles A et B, alors que le côté C2 de la cage 14 de l'autre connecteur fait face à cette même partie inférieure 103. Un tel montage tire parti du fait qu'il est possible d'introduire dans la cage 14 d'un connecteur 10 conforme à l'invention l'extrémité d'un conducteur de câble par l'un ou l'autre de ses côtés C1 ou C2.As is clear from the Figures 3 and 4 It is possible to mount two connectors 10 substantially aligning their respective jaws 15 so that their axes are coincident respective X 15 but by returning one of the connectors 10 relative to each other, so that the C side 1 of the jaw 14 of one of these connectors faces the lower portion 103 of the box 1 through which the cables A and B arrive, while the C 2 side of the cage 14 of the other connector faces this same lower part 103. Such an assembly takes advantage of the fact that it is possible to introduce into the cage 14 of a connector 10 according to the invention the end of a cable conductor by one or the other of its sides C 1 or C 2 .

Comme il ressort plus particulièrement de la figure 3, une enveloppe isolante 18 est rapportée autour des parties métalliques de chaque connecteur 10, ce qui permet d'isoler celles-ci de l'extérieur.As is clear from the figure 3 , an insulating casing 18 is attached around the metal parts of each connector 10, which allows to isolate them from the outside.

Une patte 19 est immobilisée par le boulon 13 sur la plaque 11 de chaque connecteur 10. La patte 19 comprend deux parties 191 et 192 globalement perpendiculaires. La partie 191 est plaquée contre la partie 111 de la plaque 11 par le boulon 13, alors que la partie 192 est percée d'un orifice 193 traversé par la tige d'une vis 194 destinée à former une prise mâle ou interface de branchement provisoire sur le connecteur 10.A tab 19 is immobilized by the bolt 13 on the plate 11 of each connector 10. The tab 19 comprises two parts 191 and 192 generally perpendicular. The portion 191 is pressed against the portion 111 of the plate 11 by the bolt 13, while the portion 192 is pierced with an orifice 193 traversed by the rod of a screw 194 intended to form a plug or temporary connection interface on the connector 10.

En variante, le boulon 13 peut être remplacé par d'autres modes d'assemblage, par exemple un sertissage.Alternatively, the bolt 13 may be replaced by other assembly methods, for example crimping.

Grâce à la structure des connecteurs de l'invention, il est possible de monter ceux-ci sur l'extrémité des conducteurs A1, B1, A2, B2 etc. avant de les immobiliser sur la paroi arrière 102 du coffret 1. Les connecteurs 10 sont enfilés, par leurs côtés C1 ou C2, sur les extrémités des conducteurs de câble selon qu'il s'agit de conducteurs amont ou de conducteurs aval, comme indiqué ci-dessus. Lorsqu'un connecteur a été enfilé sur un conducteur, il est alors possible de fixer ce connecteur sur la paroi 102 du coffret 1, puis de serrer la vis 16 pour immobiliser l'extrémité du conducteur dans la cage 14 du connecteur en question. Les connecteurs amont et aval étant en place, il est alors possible d'insérer dans leurs mâchoires 15 les couteaux du barreau conducteur ou d'un fusible.Thanks to the structure of the connectors of the invention, it is possible to mount them on the end of the conductors A 1 , B 1 , A 2 , B 2 etc. before immobilizing them on the rear wall 102 of the box 1. The connectors 10 are threaded, by their sides C 1 or C 2 , on the ends of the cable conductors according to whether they are upstream conductors or downstream conductors, as indicated above. When a connector has been threaded on a conductor, it is then possible to fix this connector on the wall 102 of the box 1, then to tighten the screw 16 to immobilize the end of the conductor in the cage 14 of the connector in question. The upstream and downstream connectors being in place, it is then possible to insert in their jaws 15 the knives of the conductor bar or fuse.

L'épaisseur e11 de la plaque 11 est sensiblement constante sur ses parties 111, 112 et 113. Cette épaisseur constitue l'épaisseur moyenne de la plaque 11. Elle est fixée en fonction de l'ampérage maximum prévu pour transiter dans le fusible 3. En d'autres termes, les propriétés de conduction électrique de la plaque 11, entre sa partie 111 qui forme la branche 151 de la mâchoire 15 et sa partie 117 pourvue de la denture 118, sont dépendantes de l'épaisseur e11 qui détermine la section d'écoulement du courant électrique à travers la plaque 11.The thickness e 11 of the plate 11 is substantially constant on its parts 111, 112 and 113. This thickness constitutes the average thickness of the plate 11. It is fixed according to the maximum amperage expected to pass through the fuse 3 In other words, the electrical conduction properties of the plate 11, between its part 111 which forms the branch 151 of the jaw 15 and its part 117 provided with the toothing 118, are dependent on the thickness e 11 which determines the flow section of the electric current through the plate 11.

Comme il ressort plus particulièrement de la comparaison des figures 5 et 7, cette épaisseur e11 peut varier entre les différents connecteurs du jeu de connecteurs auquel appartiennent les connecteurs des figures 4 à 6. Plus précisément, dans le cas d'un connecteur 10 représenté aux figures 5 et 6 destiné à être traversé par un courant maximum de 60 A, c'est-à-dire associé à un fusible 3 limitant le courant à 60 A, l'épaisseur e11 peut être choisie égale 2 mm, alors que, dans le cas d'un connecteur 10' représenté à la figure 7 et destiné à être traversé par un courant pouvant aller jusqu'à 90 A, l'épaisseur e11 peut être reportée à 3 mm.As is apparent in particular from the comparison of figures 5 and 7 this thickness e 11 can vary between the different connectors of the set of connectors to which the connectors of the Figures 4 to 6 . More specifically, in the case of a connector 10 shown in FIGS. Figures 5 and 6 intended to be traversed by a maximum current of 60 A, that is to say associated with a fuse 3 limiting the current to 60 A, the thickness e 11 may be chosen equal to 2 mm, whereas in the case of a connector 10 'shown in FIG. figure 7 and intended to be traversed by a current of up to 90 A, the thickness e 11 can be increased to 3 mm.

Il est ainsi possible de prévoir un jeu de connecteurs 10 de types différents pouvant être montés à l'intérieur d'un coffret du type du coffret 1 et dont les plaques 11 ont des propriétés de conduction électrique variable, en fonction de l'intensité nominale de chacun de ces connecteurs.It is thus possible to provide a set of connectors 10 of different types that can be mounted to the inside of a cabinet of the type of cabinet 1 and whose plates 11 have variable electrical conduction properties, depending on the rated current of each of these connectors.

En pratique, l'épaisseur e11 est comprise entre 0,5 et 3,5 mm pour des connecteurs 10 et 10' d'intensité nominale comprise entre 10 et 100 A.In practice, the thickness e 11 is between 0.5 and 3.5 mm for connectors 10 and 10 'of nominal intensity between 10 and 100 A.

Une autre façon de faire varier ces propriétés de conduction électrique peut être utilisée en conjonction ou à la place de la variation de l'épaisseur de la plaque 11. Elle consiste à jouer sur la nature du matériau constitutif de cette plaque, en particulier sur la composition d'un alliage dans lequel est formée cette plaque.Another way of varying these electrical conduction properties can be used in conjunction with or in place of the variation of the thickness of the plate 11. It consists in playing on the nature of the material constituting this plate, in particular on the composition of an alloy in which this plate is formed.

Dans un jeu de connecteurs conforme à l'invention, on peut tirer parti du fait que le courant transitant par les connecteurs de neutre, c'est-à-dire le courant transitant entre les conducteurs A1 et B1, est sensiblement inférieur au courant transitant par les conducteurs de phase, en particulier dans le cas d'une installation triphasée. Ainsi, la plaque 11 d'un connecteur 10" destiné à être relié à un câble de neutre peut avoir une épaisseur e11 notablement plus faible que celle des plaques des conducteurs de phase, comme représenté à la figure 8.In a set of connectors according to the invention, it can be taken advantage of the fact that the current flowing through the neutral connectors, that is to say the current flowing between the conductors A 1 and B 1 , is substantially less than current flowing through the phase conductors, in particular in the case of a three-phase installation. Thus, the plate 11 of a connector 10 "intended to be connected to a neutral cable may have a thickness e 11 which is considerably smaller than that of the plates of the phase conductors, as represented in FIG. figure 8 .

Il convient de relever ici que les parties des connecteurs 10, 10' et 10" autres que les plaques 11 sont identiques, ce qui est favorable en termes de fabrication.It should be noted here that the parts of the connectors 10, 10 'and 10 "other than the plates 11 are identical, which is favorable in terms of manufacture.

Dans le second mode de réalisation de l'invention représenté aux figures 9 et 10, les éléments analogues à ceux du premier mode de réalisation portent des références identiques. Les connecteurs 10 et 10' de ce second jeu de connecteurs comprennent chacun une plaque 11 et une lame élastique 12. La plaque 11 a globalement la même forme que la plaque correspondante des connecteurs du premier mode de réalisation. Une mâchoire 15 est définie entre deux branches 151 et 152 formées respectivement par une partie 111 de la plaque 11 et une partie 126 de la lame 12. Une cage 14 réalisée dans un profilé d'aluminium est prévue pour recevoir l'extrémité d'un conducteur de câble.In the second embodiment of the invention shown in Figures 9 and 10 elements similar to those of the first embodiment bear identical references. The connectors 10 and 10 'of this second set of connectors each comprise a plate 11 and an elastic blade 12. The plate 11 has generally the same shape as the corresponding plate of the connectors of the first embodiment. A jaw 15 is defined between two branches 151 and 152 formed respectively by a portion 111 of the plate 11 and a portion 126 of the blade 12. A cage 14 made of an aluminum profile is provided to receive the end of a cable conductor.

On note X14 l'axe central de cette cage et X15 l'axe central de la mâchoire 15. Une vis 16 est.vissée dans un taraudage traversant 141 ménagé dans un voile supérieur 142 de la cage 14. Une vis 13 est engagée dans un taraudage non réprésenté de la cage 14 et permet de plaquer, l'une contre l'autre et contre la cage 14, la plaque 11 et la lame 12. La vis 13 permet également de plaquer contre la plaque 11 une patte 19 qui supporte une vis 194 formant un organe de raccordement provisoire, comme dans le premier mode de réalisation.X 14 is the central axis of this cage and X 15 the central axis of the jaw 15. A screw 16 is screwed into a through thread 141 formed in an upper web 142 of the cage 14. A screw 13 is engaged in an unrepresented tapping of the cage 14 and makes it possible to press one against the other and against the cage 14, the plate 11 and the blade 12. The screw 13 also makes it possible to press against the plate 11 a tab 19 which supports a screw 194 forming a temporary connection member, as in the first embodiment.

Conformément à l'invention, dans le jeu de connecteurs dont deux sont représentés aux figures 9 et 10, l'épaisseur e11 de la plaque 11 est plus importante pour le connecteur 10' de la figure 10 que pour le connecteur 10 de la figure 9, le connecteur 10 de la figure 10 étant prévu pour laisser passer un courant d'ampérage plus important que celui de la figure 9.According to the invention, in the set of connectors, two of which are represented in Figures 9 and 10 , the thickness e 11 of the plate 11 is greater for the connector 10 'of the figure 10 that for the connector 10 of the figure 9 , connector 10 of the figure 10 being designed to pass a higher amperage current than that of the figure 9 .

La partie 117 de la plaque 111 qui est pourvue de la denture 118 pénètre à l'intérieur de la cage 14 par une ouverture 144. Ainsi, la conduction du courant a lieu à travers la plaque 11, sans interruption, entre un couteau installé dans la mâchoire 15 et l'extrémité d'un câble conducteur installée dans la cage 14 et dont la gaine a été perforée par la denture 118.The portion 117 of the plate 111 which is provided with the toothing 118 penetrates inside the cage 14 through an opening 144. Thus, the conduction of the current takes place through the plate 11, without interruption, between a knife installed in the jaw 15 and the end of a conductive cable installed in the cage 14 and whose sheath has been perforated by the toothing 118.

L'invention est particulièrement avantageuse en ce sens que, mises à part les plaques 11, les autres composants des types de connecteurs 10 adaptés à différents ampérages demeurent les mêmes d'un type de connecteur à l'autre, au sein d'un même jeu de connecteurs. Ceci permet de faire évoluer rapidement et d'adapter la fabrication des connecteurs en fonction des besoins, c'est-à-dire en fonction de l'ampérage à faire passer dans chaque connecteur.The invention is particularly advantageous in that, apart from the plates 11, the other components of the connector types 10 adapted to different amperages remain the same from one type of connector to another, within a single set of connectors. This makes it possible to rapidly evolve and adapt the manufacture of connectors according to the needs, that is to say according to the amperage to be passed in each connector.

Ainsi, lors de la fabrication d'un connecteur 10, 10' ou 10", on peut sélectionner la plaque 11, en fonction de l'intensité nominale du connecteur en cours de fabrication, sur la base des propriétés de conduction électrique de cette plaque. En particulier, en peut prévoir de disposer, pour la fabrication de différents connecteurs 10, 10' etc..., de plaques 11 d'épaisseur moyenne e11 de valeurs différentes et de sélectionner la plaque d'épaisseur correspondant à l'intensité nominale prévue pour un connecteur en cours de fabrication.Thus, during the manufacture of a connector 10, 10 'or 10 ", it is possible to select the plate 11, as a function of the nominal intensity of the connector being manufactured, on the basis of the electrical conduction properties of this plate. In particular, it may be possible to have, for the manufacture of different connectors 10, 10 'etc ..., plates 11 of average thickness e 11 of different values and to select the thickness plate corresponding to the intensity nominal rating for a connector being manufactured.

En variante, des plaques réalisées dans des matériaux différents peuvent être à disposition, l'une d'entre elles étant sélectionnée en fonction de l'intensité nominale prévue pour le connecteur 10 en cours de fabrication.Alternatively, plates made of different materials may be available, one of them being selected according to the rated current for the connector 10 during manufacture.

Selon une variante de l'invention qui n'est pas représentée sur les figures, la plaque 11 est pourvue, en une ou plusieurs zones localisées, d'une surépaisseur permettant d'absorber un échauffement localisé plus important, cet échauffement résultant de l'écoulement du courant. Dans ce cas également, l'épaisseur moyenne de la plaque 11 peut varier en fonction de l'ampérage nominal des connecteurs.According to a variant of the invention which is not shown in the figures, the plate 11 is provided, in one or more localized areas, with an extra thickness to absorb a larger localized heating, this heating resulting from the flow of the current. In this case too, the average thickness of the plate 11 may vary depending on the nominal amperage of the connectors.

L'invention a été représentée avec des jeux de connecteurs dont les plaques 11 ont deux ou trois épaisseurs distinctes au sein d'un même jeu. Elle s'applique également à tout jeu de connecteurs comprenant des connecteurs dont les épaisseurs ont plus de deux valeurs.The invention has been represented with sets of connectors whose plates 11 have two or three different thicknesses within the same set. It also applies to any set of connectors comprising connectors whose thicknesses have more than two values. .
