Description

DISPOSITIF DE RACCORDEMENT PAR SERRAGE MéCANIQUE D'UN CABLE
OU D'UNE BARRE DE CONNEXION A UNE PLAGE DE CONTACT D'UN
APPAREIL ELECTRIQUE. DEVICE FOR MECHANICAL TIGHTENING OF A CABLE
OR OF A CONNECTION BAR TO A CONTACT RANGE OF A
ELECTRICAL APPLIANCE.

L'invention est relative à un dispositif de raccordement à serrage mécanique d'un conducteur de connexion extérieure à une plage de contact d'un appareil électrique à boitier moulé, et comprenant un étrier métallique muni d'un taraudage pour le passage d'une vis de serrage susceptible d'assurer un contact direct entre le conducteur de connexion et la plage, cette dernière faisant saillie du boîtier et étant percée d'un trou.The invention relates to a device for mechanically tightening a connection conductor external to a contact pad of an electrical appliance with molded housing, and comprising a metal stirrup provided with a thread for the passage of a clamping screw capable of ensuring direct contact between the connection conductor and the pad, the latter projecting from the housing and being pierced with a hole.

Un dispositif de raccordement connu du genre mentionné est décrit en détail dans le brevet français NO 2.032.056 de la demanderesse. Le-conducteur de connexion extérieure est constitué soit par un câble, soit par une barre méplate.A known connection device of the kind mentioned is described in detail in French patent No. 2,032,056 of the applicant. The external connection conductor consists either of a cable or of a flat bar.

L'étrier métallique sert uniquement lors du raccordement par câble, mais est inutilisé lors du raccordement par barre. Cette dernière est dotée d'un trou destiné à être superposé au trou de la plage de contact. Le serrage entre la plage et la barre méplate s'opère au moyen d'une simple vis de fixation coopérant soit avec un écrou auxiliaire, soit avec des filetages pratiqués dans l'un des trous. Le passage du raccordement par barre à celui par câble s'effectue par addition de l'étrier de serrage autour de la plage. Ce dispositif fait intervenir des pièces différentes en fonction du mode de raccordement choisi, ce qui augmente le coût de fabrication et complique le stockage.The metal bracket is only used when connecting by cable, but is not used when connecting by bar. The latter has a hole intended to be superimposed on the hole of the contact pad. The tightening between the track and the flat bar is effected by means of a simple fixing screw cooperating either with an auxiliary nut, or with threads made in one of the holes. The transition from the bar to the cable connection is made by adding the clamping bracket around the shelf. This device involves different parts depending on the connection method chosen, which increases the manufacturing cost and complicates storage.

La présente invention a pour but de remédier à ces inconvénients et de permettre la réalisation d'un dispositif de raccordement standard utilisant les mêmes pièces- indépen- damment du mode de raccordement choisi.The object of the present invention is to remedy these drawbacks and to allow the production of a standard connection device using the same parts, regardless of the connection mode chosen.

Le dispositif de raccordement selon l'invention est caractérisé par le fait que itétrier coopère avec la plage de contact pour constituer soit une cage de serrage destinée à entour la plage lors d'un raccordement par câble inséré entre le berceau inférieur de la cage et la face inférieure de la plage, la vis de serrage prenant appui sur une pièce intermédiaire disposée sur la face supérieure de la plage pour recouvrir le trou, soit un écrou accolé à la face inférieure de la plage lors d'un raccordement par barre, cette dernière étant serrée contre la face supérieure de la plage au moyen de la vis introduite dans ledit écrou dont le taraudage se trouve en regard du trou de la plage.The connection device according to the invention is characterized in that the itétrier cooperates with the contact pad to constitute either a clamping cage intended to surround the pad during a connection by cable inserted between the lower cradle of the cage and the underside of the pad, the clamping screw resting on an intermediate piece placed on the top face of the pad to cover the hole, i.e. a nut attached to the underside of the pad during a bar connection, the latter being tightened against the upper face of the pad by means of the screw inserted in said nut, the thread of which is located opposite the hole in the pad.

On remarque que le dispositif de raccordement comprend un ensemble de trois pièces métalliques distinctes, à savoir l'étrier, la vis et la pièce intermédiaire. Le passage d'un raccordement à l'autre s'opère par modification de l'association des mêmes pièces sans utilisation d'éléments auxiliaires.It is noted that the connection device comprises a set of three separate metal parts, namely the bracket, the screw and the intermediate part. The passage from one connection to the other takes place by modification of the association of the same parts without the use of auxiliary elements.

La pièce intermédiaire est agencée pour servir de rondelle intercalée entre la tête de vis et la face supérieure de la barre de connexion. Elle présente notamment une forme d'équerre dont l'une des ailes sert d'appui à la vis en cas de raccordement par câble, et dont l'autre aile est percée d'un trou pour le passage de la vis en cas de raccordement par barre.The intermediate piece is arranged to serve as a washer interposed between the screw head and the upper face of the connection bar. It has in particular a square shape, one of the wings of which serves as a support for the screw in the case of cable connection, and the other wing of which is pierced with a hole for the passage of the screw in the event of connection. per bar.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre d'un mode de mise en oeuvre de l'invention, donné à titre d'exemple non limitatif et représenté au dessin annexé, dans lequel la figure 1 montre une vue en élévation du dispositif selon l'invention de raccordement d'un câble; la figure 2 est une vue en coupe selon la ligne II-II de la fig. 1; la figure 3 représente une vue identique à la fig. 1 d'un raccordeme t par barre; la figure 4 est une -vue en coupe selon la ligne IV-IV de la fig. 3.Other advantages and characteristics of the invention will emerge from the description which follows of an embodiment of the invention, given by way of nonlimiting example and represented in the appended drawing, in which FIG. 1 shows an elevational view of the device according to the invention for connecting a cable; Figure 2 is a sectional view along line II-II of FIG. 1; FIG. 3 represents a view identical to FIG. 1 of a connection per bar; Figure 4 is a sectional view along line IV-IV of FIG. 3.

Sur les figures, est représenté un dispositif de raccordement 10 mixted'unlcâble électrique 12 ou d'une barre de connexion 14 sur une plage de contact 1.. d'un appareil électrique à basse tension, notamment un disjoncteur à boîtier 18 en matériau isolant moulé. La plage de contact 16 fait saillie du boîtier 18 isolant et comporte un trou 20 de diamètre normalisé en ponction du calibre de l'appareil.In the figures, there is shown a connection device 10 mixted of an electrical cable 12 or of a connection bar 14 on a contact pad 1 .. of a low-voltage electrical appliance, in particular a case circuit breaker 18 made of insulating material mold. The contact pad 16 protrudes from the insulating housing 18 and includes a hole 20 of standardized diameter as a puncture of the gauge of the device.

Le dispositif de raccordement 10 est associé à la plage 1 dans un alvéole 22 extérieur du boîtier 18. L'alvéole 22 est délimité par deux rebords supérieur 24 et inférieur 26 et par deux flancs latéraux 30, 32, formés par des extensions du bolier 18 moulé. Le rebord 24 supérieur est do-té d'une ouverture 28 alignée verticalement avec le trou 20 de la plage de contact 16. L'entrée de l'alvéole 22 est limitée à sa base par deux butées 34, 36 rectangulaires solidaires du rebord inférieur 26 et symétriques par rapport au plan médian vertical de trace XX' (fig. 1 et-3).The connection device 10 is associated with the track 1 in a cell 22 outside the housing 18. The cell 22 is delimited by two upper 24 and lower 26 edges and by two lateral flanks 30, 32, formed by extensions of the bolier 18 mold. The upper edge 24 is do-ted with an opening 28 vertically aligned with the hole 20 of the contact pad 16. The entry of the cell 22 is limited at its base by two rectangular stops 34, 36 integral with the lower edge 26 and symmetrical with respect to the vertical median plane of trace XX '(fig. 1 and -3).

La plage 16 horizontale est agencée sensiblement à mi-hauteur de l'alvéole 22 et est séparée verticalement des butées 34, 36 par une distance d prédéterminée autorisant l'engagement du dispositif 10 sur la plage 16.The horizontal track 16 is arranged substantially at mid-height of the cell 22 and is vertically separated from the stops 34, 36 by a predetermined distance d allowing the engagement of the device 10 on the track 16.

Le dispositif de raccordement 10 comporte un ensemble de trois éléments métalliques distincts - un étrier 38 en forme de cage susceptible d'être enfile
ou accolé à la plage 16-selon le mode de raccordement
choisi, crest-à-dire par câble ou par barre, - une vis de serrage 40 destinée à être engagée dans un
taraudage 42 de l'étrier 38, - et une pièce 44 intermédiaire en forme d'équerre murtie
d'une ailc 44a non perforée, et d'une autre aile 44b
perpendieulaire à trou 46 don t le diamètre correspond à
celui de la plage 16.The connection device 10 comprises a set of three distinct metallic elements - a stirrup 38 in the form of a cage capable of being put on
or attached to the range 16-depending on the connection method
chosen, ie by cable or by bar, - a clamping screw 40 intended to be engaged in a
thread 42 of the stirrup 38, - and an intermediate piece 44 in the form of a wall bracket
an unperforated wing 44a, and another wing 44b
perpendicular to hole 46 don t the diameter corresponds to
that of beach 16.

Les trois éléments 33, 40, 44 constitutifs du dispositif de raccordement 10 sont standards, indépendamment du mode de raccordement par câble ou par barre, le passage d'un raccordement à l'autre s'opérant par simple modification de l'association des memes éléments sans utilisation de pièces additionnelles ou de structures différentes. La fenêtre de l'étrier 38 présente une dimension L1 extérieure supérieure à l'intervalle l transversal, ménagé entre les butées 3X, 36 de l'entrée inférieure de L'alvéole 22. La dimension intérieure de la fenêtre de l'étrier 35 est legerenent supérieure à la largeur de la plage de contact 1G pour autoriser l'insertion de l'étrier 38 autour de- la plage 16 lors d'un raccordement par câble.La profondeur
L2 de i'étrier 38 est inférieure à l'intervalle l et correspond sensiblement à la largeur de la plage de contact 16.The three elements 33, 40, 44 constituting the connection device 10 are standard, independently of the mode of connection by cable or by bar, the passage from one connection to the other taking place by simple modification of the association of the same elements without the use of additional parts or different structures. The stirrup window 38 has an outer dimension L1 greater than the transverse interval l, formed between the stops 3X, 36 of the lower inlet of the cell 22. The inner dimension of the stirrup window 35 is slightly greater than the width of the contact area 1G to allow the insertion of the stirrup 38 around the area 16 during a cable connection.
L2 of the stirrup 38 is less than the interval l and corresponds substantially to the width of the contact pad 16.

Le dispositif de raccordement 10 selon l'invention est mis en oeuvre de la maniere suivante :
Lors d'un raccordement par câble 12 (fig. 1 et 2) la pièce 44 intermédiaire est positionnée sur la face supérieure de la plage de contact 16 tel que l'aile 44a non perforée recouvre le trou 20 de la plage. L'ensemble étrier 38 et vis de serrage 40 est ensuite inséré sur la plage 16 à l'intérieur de l'alvéole 22 jusqu'a' une position d'alignement de la vis 40 avec ltouverture 25 du rebord supérieur 24. La distance d entre la face inférieure de la plage 16 et le plan horizontal formé par les épaulements des butées 34,36 zst supérieure à i'épaisseur de la paroi de l'étrier 38 pour permettre son insertion par translation selon le sens de la flèche F sur la plage 16. En position insérée sur la plaa-essltétrier 38 est sollicité vers le fond de l'alvéole 22 par dévissaqe de la vis 40. The connection device 10 according to the invention is implemented in the following manner:
During a cable connection 12 (fig. 1 and 2) the intermediate piece 44 is positioned on the upper face of the contact pad 16 such that the non-perforated wing 44a covers the hole 20 in the pad. The assembly of caliper 38 and clamping screw 40 is then inserted on the pad 16 inside the cell 22 until a position of alignment of the screw 40 with the opening 25 of the upper rim 24. The distance d between the underside of track 16 and the horizontal plane formed by the shoulders of the stops 34.36 zst greater than the thickness of the wall of the stirrup 38 to allow its insertion by translation in the direction of the arrow F on the track 16. In the inserted position on the pla-essltétrier 38 is biased towards the bottom of the cell 22 by unscrewing the screw 40.

La partie dénudée du câble 12 est ensuite engagée selon le sens de la flèche F dans l'espace ménagé entre le berceau inférieur de l'étrier 38 et la face inférieure de la plage de contact 16. Le vissage de la vis 40 au moyen d'un tournevis introduit dans l'ouverture 28 provoque la montée de l'étrier 38 et le serrage par contact direct du câble contre la plage 16 On remarque que l'étrier 38 est emprisonné dans l'alvéole 22 avant et après serrage de la vis 40 grâce à la présence des butées 34, 36. La pièce intermédiaire 44 reste fixe sur la plage durant l'opération de raccordement et sert uniquement de plaque d'appui à l'extrémité de la vis 40. The stripped part of the cable 12 is then engaged in the direction of the arrow F in the space provided between the lower cradle of the stirrup 38 and the lower face of the contact pad 16. The screwing of the screw 40 by means of 'a screwdriver inserted in the opening 28 causes the mounting of the stirrup 38 and the tightening by direct contact of the cable against the pad 16 It is noted that the stirrup 38 is trapped in the cavity 22 before and after tightening of the screw 40 by virtue of the presence of the stops 34, 36. The intermediate piece 44 remains fixed on the surface during the connection operation and serves only as a support plate at the end of the screw 40.

Lors d'un raccordement par barre 14 de connexion extérieure (fig. 3 et 4), l'étrier 38 subit une rotation de 90 degrés autour d'un axe vertical et est introduit par translation (flèche F) dans l'entrée rétrécie de l'alvéole 22 ménagée entre les butées 34, 36. L'étrier 38 est ainsi logé dans le compartiment inférieur de l'alvéole 22 entre la face inférieure de la plage 16 et le rebord 26 inférieur du boltier 18, et son taraudage 42 est situé à proximité et dans l'alignement vertical du trou 20 de la plage de contact 16.When connected by bar 14 of external connection (fig. 3 and 4), the bracket 38 undergoes a rotation of 90 degrees around a vertical axis and is introduced by translation (arrow F) in the narrowed entry of the cell 22 formed between the stops 34, 36. The stirrup 38 is thus housed in the lower compartment of the cell 22 between the lower face of the pad 16 and the lower flange 26 of the boltier 18, and its thread 42 is located near and in the vertical alignment of the hole 20 of the contact pad 16.

A l'opposé de l'étrier 38, la barre 1-4 de connexion, munie d'un trou 50 pour le passage de la vis 40, prend appui sur la face supérieure de la plage 16, alors que l'aile 44b perforée de la pièce intermédiaire 44 est insérée entre la barre 14 et la tête de vis 40. Les trois trous 20,50, 46 respectifs de la plage 16 de la barre 14 et de la pièce 44 sont alignés selon l'axe vertical XX' et traversés par la vis de serrage 40 dont le vissage dans le taraudage 42 de l'étrier 38 fixe assure le contact direct entre la barre de connexion 14 et la plage 16 correspondante La plage 16 et la barre 14 sont pris en sandwich entre la pièce intermédiaire 44 Jouant le rôle de rondelle, et l'étrier 38 servant d'écrou fixe à la vis 40.Opposite the stirrup 38, the connection bar 1-4, provided with a hole 50 for the passage of the screw 40, bears on the upper face of the track 16, while the wing 44b is perforated of the intermediate piece 44 is inserted between the bar 14 and the screw head 40. The three respective holes 20, 50, 46 of the area 16 of the bar 14 and of the piece 44 are aligned along the vertical axis XX 'and crossed by the clamping screw 40, the screwing in the tapping 42 of the fixed bracket 38 ensures direct contact between the connection bar 14 and the corresponding pad 16 The pad 16 and the bar 14 are sandwiched between the intermediate piece 44 Acting as a washer, and the bracket 38 serving as a fixed nut for the screw 40.

La modification du positionnement de l'étrier 38 et de la pièce intermédiaire 44 dans l'alvéole 22 permet de passer facilement d'un mode de raccordement à l'autre en utili ant la même vis de serrage 40. La pièce intermédiaire 44 en L peut présenter une structure quelcorque, comprenant une première zone d'appui de l'extrémité de la vis 40 lors du raccordement par câble, et une deuxième zone dotée d'un trou de passage de la vis 40 lors du raccordement par barre.The modification of the positioning of the stirrup 38 and of the intermediate piece 44 in the socket 22 makes it possible to easily switch from one connection mode to the other by using the same clamping screw 40. The intermediate piece 44 in L may have any structure, comprising a first support area of the end of the screw 40 when connecting by cable, and a second area provided with a through hole for the screw 40 when connecting by bar.

L'invention n' est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit et repre senté au dessin annexé, mais elle s'étend bien au contraire à toute variante restant dans le cadre des équivalences électrotechniques, notamment celle dans laquelle l'aile 44a non perforée de la pièce intermédiaire 44 est équipée d'un tenon qui s'insère et emplit dans sa quasi-totalité le trou 20 de la plage 16 lors du raccordement par cabale. The invention is of course in no way limited to the embodiment more particularly described and represented in the appended drawing, but it extends on the contrary to any variant remaining within the framework of electrotechnical equivalences, in particular that in which the 'wing 44a non-perforated intermediate piece 44 is equipped with a pin which is inserted and fills in almost all of the hole 20 of the range 16 during connection by cabal.
