Description

L'invention concerne un connecteur de raccordement d'un conducteur de câble à un couteau de fusible ou de barreau conducteur.The invention relates to a connector for connecting a cable conductor to a fuse knife or conducting bar.

Une pluralité de tels connecteurs équipent un coffret de raccordement de câbles amont et aval par l'intermédiaire d'un fusible ou d'un barreau conducteur.A plurality of such connectors equip an upstream and downstream cable connection box via a fuse or a conductive bar.

Le document de brevet WO 2007/085746 décrit un tel connecteur représenté sur la figure 1 en coupe transversale.The patent document WO 2007/085746 describes such a connector shown on the figure 1 in cross section.

Selon ce document, le connecteur 10 comprend une cage 14 de réception d'une extrémité de conducteur et une mâchoire 15 de réception d'un couteau, la mâchoire du connecteur étant formée par une plaque 11 de matériau électriquement conducteur, qui constitue une des branches 151 de la mâchoire, et une lame 12 élastiquement déformable qui constitue l'autre branche 152 de la mâchoire.According to this document, the connector 10 comprises a cage 14 for receiving a conductor end and a jaw 15 for receiving a knife, the jaw of the connector being formed by a plate 11 of electrically conductive material, which constitutes one of the branches 151 of the jaw, and an elastically deformable blade 12 which constitutes the other branch 152 of the jaw.

La mâchoire 15 est donc 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.The jaw 15 is thus 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.

La plaque 11 et la lame 12 sont rapportées sur la cage 14 réalisée dans un profilé d'aluminium. Par ailleurs, la plaque 11 est pourvue d'une partie dentée 117 reçue à l'intérieur de la cage 14 et destinée à perforer une gaine isolante d'une extrémité de conducteur, par serrage d'une vis de serrage 16 vissée dans un taraudage traversant 141 ménagé dans un voile supérieur 142 de la cage 14.The plate 11 and the blade 12 are attached to the cage 14 made of an aluminum profile. Furthermore, the plate 11 is provided with a toothed portion 117 received inside the cage 14 and intended to perforate an insulating sheath of a conductor end, by tightening a clamping screw 16 screwed into a tapping. through 141 formed in an upper web 142 of the cage 14.

Une vis 13 est engagée dans un taraudage 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.A screw 13 is engaged in a tapping of the cage 14 and makes it possible to press the plate 11 and the blade 12 against each other and against the cage 14. The screw 13 also makes it possible to press against the plate 11 a tab 19 which supports a screw 194 forming an organ of temporary connection.

La partie 117 de la plaque 11 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 11 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.

Un tel agencement de connecteur comporte un nombre relativement important de pièces qu'il est nécessaire de fixer ensemble par une vis. La gestion du stockage des pièces et sa fabrication sont donc relativement complexes et il en résulte qu'il est relativement coûteux.Such a connector arrangement has a relatively large number of parts that need to be fastened together by a screw. The management of the storage of parts and its manufacture are therefore relatively complex and as a result it is relatively expensive.

L'invention résout ce problème en proposant un connecteur constitué d'un nombre de pièces réduit tout en étant de fabrication simple.The invention solves this problem by proposing a connector consisting of a reduced number of parts while being simple to manufacture.

Pour ce faire, l'invention propose un connecteur de raccordement d'un conducteur de câble à un couteau de fusible ou de barreau conducteur et comprenant une cage de réception d'une extrémité de conducteur et une mâchoire de réception d'un couteau, de section en U, la mâchoire du connecteur étant formée uniquement par une plaque de matériau électriquement conducteur, qui constitue une des branches du U de la mâchoire et est solidaire de ladite cage par la base dudit U, et une lame élastiquement déformable qui constitue l'autre branche du U de la mâchoire, ladite lame élastiquement déformable étant constituée d'une pièce indépendante fixée, caractérisé en ce que ladite cage et ladite plaque sont constituées d'une seule pièce dans un profilé de matériau électriquement conducteur, et en ce que ce profilé comporte une rainure disposé dans la base dudit U et recevant un bord de fixation de ladite lame élastiquement déformable.To do this, the invention proposes a connector for connecting a cable conductor to a fuse knife or conductor bar and comprising a receiving cage of a conductor end and a jaw for receiving a knife, U-shaped section, the jaw of the connector being formed solely by a plate of electrically conductive material, which constitutes one of the branches of the U of the jaw and is integral with said cage by the base of said U, and an elastically deformable blade which constitutes the another branch of the U of the jaw, said elastically deformable blade consisting of a fixed independent part, characterized in that said cage and said plate are constituted in one piece in a section of electrically conductive material, and in that profile comprises a groove disposed in the base of said U and receiving a fixing edge of said elastically deformable blade.

Selon un mode de réalisation préféré, ladite rainure est parallèle au bord libre de ladite plaque et est disposée dans la base dudit U.According to a preferred embodiment, said groove is parallel at the free edge of said plate and is disposed in the base of said U.

Dans ce cas, de préférence, ledit bord de fixation de ladite lame élastiquement déformable comporte une languette découpée et inclinée dans le sens longitudinal de ladite rainure.In this case, preferably, said fixing edge of said elastically deformable blade comprises a tongue cut and inclined in the longitudinal direction of said groove.

De préférence, ladite rainure du profilé a une section en L correspondante à la forme dudit bord de fixation de la lame élastiquement déformable.Preferably, said groove of the profile has an L-shaped section corresponding to the shape of said fixing edge of the elastically deformable blade.

Avantageusement, ladite cage comporte une partie dentée réalisée dans ledit profilé et destinée à perforer une gaine isolante d'une extrémité de conducteur.Advantageously, said cage comprises a toothed portion formed in said profile and intended to perforate an insulating sheath of a conductor end.

Comme selon l'art antérieur, selon l'invention, un connecteur de raccordement d'un conducteur de câble à un couteau de fusible ou de barreau conducteur comprend une cage 214 de réception d'une extrémité de conducteur et une mâchoire de réception d'un couteau, de section en U, la mâchoire du connecteur étant formée par une plaque 211 de matériau électriquement conducteur, qui constitue une des branches du U de la mâchoire, et une lame élastiquement déformable 212 constituée d'une pièce indépendante fixée.As according to the prior art, according to the invention, a connector for connecting a cable conductor to a fuse knife or conductor bar comprises a receiving cage 214 of a conductor end and a receiving jaw of a knife, of U-shaped section, the jaw of the connector being formed by a plate 211 of electrically conductive material, which constitutes one of the branches of the U of the jaw, and an elastically deformable blade 212 consisting of a fixed independent part.

Selon l'invention et comme représenté sur la figure 2, la cage 214 et la plaque 211 sont constituées d'une seule pièce dans un profilé 200 de matériau électriquement conducteur, de préférence en aluminium, et ce profilé comporte une rainure 201 disposé dans la base dudit U et recevant un bord de fixation de la lame élastiquement déformable.According to the invention and as shown on the figure 2 , the cage 214 and the plate 211 consist of a single piece in a profile 200 of electrically conductive material, preferably aluminum, and this profile comprises a groove 201 disposed in the base of said U and receiving a fixing edge of the elastically deformable blade.

Cette rainure 201 est parallèle au bord libre de ladite plaque 211 et est disposée dans la base dudit U.This groove 201 is parallel to the free edge of said plate 211 and is disposed in the base of said U.

Par ailleurs, la cage 214 comporte une partie dentée 218 réalisée dans le profilé 200 et destinée à perforer une gaine isolante d'une extrémité de conducteur.Furthermore, the cage 214 comprises a toothed portion 218 made in the section 200 and intended to perforate an insulating sheath of a conductor end.

La lame élastiquement déformable 212, de préférence en acier inoxydable, est quant à elle représentée sur le figures 3A et 3B.The elastically deformable blade 212, preferably made of stainless steel, is represented on the Figures 3A and 3B .

Le bord de fixation de cette lame 212 destiné à être reçu dans la rainure 201 du profilé 200 présente une bande 203 pliée perpendiculairement à la surface de la lame 212 qui comporte une languette 204 découpée et inclinée dans le sens longitudinal de cette bande. En revenant sur la figure 2, la rainure 201 du profilé 200 a donc une section en L correspondante à la forme du bord de fixation 203 de la lame élastiquement déformable 212.The fixing edge of this blade 212 intended to be received in the groove 201 of the section 200 has a band 203 folded perpendicularly to the surface of the blade 212 which has a tab 204 cut and inclined in the longitudinal direction of this strip. Returning to the figure 2 , the groove 201 of the profile 200 thus has an L-shaped section corresponding to the shape of the attachment edge 203 of the elastically deformable blade 212.

Le connecteur 210 selon l'invention tel que représenté sur les figures 4 et 5 est fabriqué selon le procédé suivant.The connector 210 according to the invention as represented on the figures 4 and 5 is manufactured according to the following method.

Ce procédé consiste à introduire par coulissement longitudinal le bord de fixation 203 de la lame élastiquement déformable dans la rainure 201 du profilé 200 au moyen d'une presse, la languette 204 assurant par déformation la fixation définitive de la lame élastiquement déformable 212 sur le profilé 200.This method consists in introducing by longitudinal sliding the fixing edge 203 of the elastically deformable blade in the groove 201 of the profile 200 by means of a press, the tab 204 ensuring by deformation the final fixing of the elastically deformable blade 212 on the profile 200.

A titre d'exemple, la rainure 201 comporte une branche horizontale d'une largeur d'environ 7 mm et d'une hauteur d'environ 2 mm et la lame élastiquement déformable 211 a une épaisseur d'environ 1 mm, la languette 204 faisant saillie du plan du bord de fixation 203 sur une hauteur d'environ 2 mm.For example, the groove 201 comprises a horizontal branch of a width of about 7 mm and a height of about 2 mm and the elastically deformable blade 211 has a thickness of about 1 mm, the tongue 204 protruding from the plane of the fixing edge 203 to a height of about 2 mm.

Une fois ces deux parties assemblées, le connecteur 210 est équipé d'une vis de serrage 216 vissée dans un taraudage traversant 241 ménagé dans un voile supérieur 242 de la cage 214 et installé dans un boîtier 250, comme illustré sur la figure 5.Once these two parts are assembled, the connector 210 is equipped with a clamping screw 216 screwed into a through thread 241 formed in an upper web 242 of the cage 214 and installed in a housing 250, as shown in FIG. figure 5 .
