La présente invention concerne un appareil électrique comprenant au moins une borne de raccordement à ressort.The present invention relates to an electrical apparatus comprising at least one spring connection terminal.

Ce type d'appareil électrique comporte de façon connue un corps en matériau isolant présentant une face arrière comprenant des moyens de fixation sur un support, une face avant opposée à la face arrière. Chaque borne de raccordement à ressort est logée dans le corps en matériau isolant et comprend :

  • une pièce de connexion, reliée à une barrette conductrice, permettant d'assurer la connexion d'au moins un fil conducteur avec des composants électriques,
  • au moins un ressort de serrage destiné à maintenir l'extrémité d'un fil conducteur en contact avec la pièce de connexion.
This type of electrical apparatus comprises in known manner a body of insulating material having a rear face comprising means for fixing on a support, a front face opposite to the rear face. Each spring connection terminal is housed in the body of insulating material and comprises:
  • a connection piece, connected to a conductive strip, making it possible to connect at least one conductive wire to electrical components,
  • at least one clamping spring for holding the end of a lead wire in contact with the connection piece.

De plus, le corps en matériau isolant comprend au moins une ouverture de raccordement avant ménagée sur la face avant de l'appareil électrique et permettant l'introduction du fil conducteur dans un premier logement ménagé dans la borne de raccordement.In addition, the body of insulating material comprises at least one front connection opening formed on the front face of the electrical apparatus and allowing the introduction of the conductive wire into a first housing formed in the connection terminal.

En particulier, le document DE 10-2005 016534 décrit un tel type d'appareil.In particular, the document DE 10-2005 016534 describes such a type of apparatus.

Lorsqu'un opérateur souhaite réaliser le raccordement de deux appareils électriques du type précité, il utilise généralement un organe de liaison électrique comprenant deux fiches conductrices destinées respectivement à être insérées dans une borne de raccordement de l'un des appareils électriques par l'intermédiaire des ouvertures de raccordement ménagées sur les faces avant des appareils.When an operator wishes to make the connection of two electrical appliances of the aforementioned type, he generally uses an electrical connection member comprising two conductive plugs respectively intended to be inserted into a connection terminal of one of the electrical appliances via the intermediaries. connection openings on the front of the devices.

De ce fait, il n'est plus possible d'utiliser ces bornes pour le raccordement de fils conducteurs sur l'appareil.Therefore, it is no longer possible to use these terminals for the connection of conductors son on the device.

En outre, puisque le raccordement des deux appareils est réalisé à l'aide d'un organe de liaison électrique positionné sur les faces avant des appareils, il en résulte un important encombrement de l'ensemble.In addition, since the connection of the two devices is achieved by means of an electrical connection member positioned on the front faces of the apparatus, the result is a large overall size of the assembly.

Le problème technique à la base de l'invention consiste donc à fournir un appareil électrique permettant un raccordement de deux appareils électriques sans empêcher l'utilisation des bornes de raccordement de ces derniers pour le raccordement de fils conducteurs, tout en limitant l'encombrement en hauteur de l'ensemble.The technical problem underlying the invention is therefore to provide an electrical apparatus for connecting two electrical appliances without preventing the use of the connection terminals thereof for connecting conductive wires, while limiting the overall dimensions. height of the whole.

A cet effet, la présente invention concerne un appareil électrique destiné à être fixé sur un rail support du type précité, caractérisé en ce que la pièce de connexion comprend un second logement destiné à recevoir une fiche conductrice d'un autre appareil électrique ou d'un organe de liaison électrique, ce second logement étant situé en regard d'une ouverture de raccordement latérale ménagée dans une face latérale du corps en matériau isolant, s'étendant transversalement entre les faces avant et arrière.For this purpose, the present invention relates to an electrical apparatus intended to be fixed on a support rail of the aforementioned type, characterized in that the connection piece comprises a second housing for receiving a conductive plug of another electrical apparatus or an electrical connection member, this second housing being situated opposite a lateral connection opening formed in a lateral face of the body insulating material, extending transversely between the front and rear faces.

Ainsi, puisque la pièce de connexion comporte un second logement situé en regard d'une ouverture de raccordement ménagée dans une face latérale du corps isolant, il est possible de réaliser un raccordement latéral de deux appareils électriques par l'intermédiaire d'un organe de liaison électrique adapté comportant sur ses deux faces latérales opposées, une fiche conductrice présentant une forme complémentaire du second logement de la pièce de connexion de chaque appareil électrique à raccorder.Thus, since the connecting piece comprises a second housing located opposite a connection opening formed in a side face of the insulating body, it is possible to make a lateral connection of two electrical devices via a control member. adapted electrical connection comprising on its two opposite lateral faces, a conductive plug having a shape complementary to the second housing of the connection piece of each electrical appliance to be connected.

Ce raccordement latéral des deux appareils électriques permet de laisser libre accès aux ouvertures de raccordement ménagées sur les faces avant des appareils électriques, ce qui permet donc l'utilisation des bornes de raccordement de chaque appareil pour le raccordement de fils conducteurs.This lateral connection of the two electrical devices allows free access to the connection openings provided on the front faces of the electrical appliances, which thus allows the use of the connection terminals of each device for the connection of conducting wires.

En outre, ce raccordement latéral permet de limiter l'encombrement en hauteur de l'ensemble.In addition, this lateral connection limits the overall height of the assembly.

Avantageusement, la pièce de connexion est constituée par un organe conducteur fixé sur la barrette conductrice.Advantageously, the connecting piece is constituted by a conductive member fixed on the conductive strip.

Selon une autre caractéristique de l'invention, le second logement est délimité d'une part par un évidement ménagé dans la pièce de connexion, et d'autre part par la barrette conductrice.According to another characteristic of the invention, the second housing is delimited on the one hand by a recess in the connection piece, and on the other hand by the conductive bar.

De préférence, la pièce de connexion présente une forme générale du U dont la base est fixée sur la barrette conductrice.Preferably, the connecting piece has a general shape of the U whose base is fixed on the conductive strip.

La présente invention concerne également un ensemble électrique comprenant un appareil électrique selon l'invention et un organe de liaison électrique comprenant sur au moins l'une de ces faces au moins une fiche conductrice présentant une forme complémentaire du second logement de la pièce de connexion et destinée à être insérée dans ce dernier par l'intermédiaire de l'ouverture de raccordement ménagée dans une face latérale du corps en matériau isolant.The present invention also relates to an electrical assembly comprising an electrical apparatus according to the invention and an electrical connection member comprising on at least one of these faces at least one conductive plug having a shape complementary to the second housing of the connecting piece and intended to be inserted into the latter through the connection opening formed in a side face of the body of insulating material.

Avantageusement, l'organe de liaison électrique comporte un corps en matériau isolant comprenant deux faces latérales opposées sensiblement parallèles, chaque face latérale du corps isolant comportant au moins une fiche conductrice présentant une forme complémentaire du second logement de la pièce de connexion.Advantageously, the electrical connection member comprises a body of insulating material comprising two substantially parallel opposite side faces, each lateral face of the insulating body comprising at least one plug conductive having a shape complementary to the second housing of the connection piece.

De préférence, chaque fiche conductrice comporte une barrette conductrice et une lame élastique.Preferably, each conductive plug comprises a conductive bar and an elastic blade.

Figures 5 et 6 sont des vues en perspective de la borne de raccordement de la figure 4.Figures 5 and 6 are perspective views of the connection terminal of Figure 4.

La figure 1 représente un appareil électrique 2 destiné à être fixé sur un rail support 3. Selon le mode de réalisation représenté aux figures, l'appareil électrique 2 est un contacteur électrique.FIG. 1 represents an electrical apparatus 2 intended to be fixed on a support rail 3. According to the embodiment represented in the figures, the electrical apparatus 2 is an electric contactor.

L'appareil électrique 2 comporte un corps en matériau isolant 4 présentant une face arrière 5 comprenant des moyens de fixation 6 sur le rail support 3, une face avant 7 opposée à la face arrière, et des faces latérales 8, 9 sensiblement parallèles et perpendiculaires aux faces avant et arrière.The electrical apparatus 2 comprises a body of insulating material 4 having a rear face 5 comprising fixing means 6 on the support rail 3, a front face 7 opposite to the rear face, and side faces 8, 9 substantially parallel and perpendicular. front and back faces.

L'appareil électrique 2 comprend deux bornes de raccordement à ressort logées dans le corps en matériau isolant 4, respectivement à proximité des faces latérales.The electrical apparatus 2 comprises two spring-loaded connection terminals housed in the body of insulating material 4, respectively close to the lateral faces.

Comme montré aux figures 4 à 6, chaque borne de raccordement comprend :

  • une pièce de connexion 11 constituée par un organe conducteur présentant une forme générale de U dont la base est soudée sur une barrette conductrice 12,
  • deux ressorts de serrage 13 fixés entre les branches de l'organe conducteur et destinés à maintenir chacun l'extrémité d'un fil conducteur en contact avec la pièce de connexion.
As shown in FIGS. 4 to 6, each connection terminal comprises:
  • a connection piece 11 constituted by a conductive member having a generally U-shaped whose base is welded to a conductive strip 12,
  • two clamping springs 13 fixed between the branches of the conductive member and for holding each end of a conductive wire in contact with the connecting piece.

La pièce de connexion 11 permet donc d'assurer la connexion de deux fils conducteurs avec des composants électriques reliés à la barrette conductrice 12.The connection piece 11 thus makes it possible to connect two conductive wires with electrical components connected to the conductive strip 12.

Comme représenté à la figure 2, le corps en matériau isolant 4 comprend quatre ouvertures de raccordement avant 14 et quatre ouvertures d'actionnement 15 ménagées sur la face avant 7 de l'appareil électrique, les ouvertures de raccordement et d'actionnement étant associées par paire à un ressort de serrage 13.As shown in Figure 2, the body of insulating material 4 comprises four front connection openings 14 and four actuating openings 15 formed on the front face 7 of the electrical apparatus, the connection and actuating openings being associated by pair with a clamping spring 13.

Il doit être noté que chaque ouverture de raccordement 14 permet l'introduction d'un fil conducteur dans un logement ménagé dans le ressort de serrage correspondant tandis que chaque ouverture d'actionnement 15 permet l'introduction de la pointe d'un outil d'actionnement 16 entre les branches de la pièce de connexion 11 de manière à actionner le ressort de serrage correspondant.It should be noted that each connection opening 14 allows the introduction of a conductive wire into a housing formed in the corresponding clamping spring while each actuating opening 15 allows the introduction of the tip of a tool. actuation 16 between the branches of the connecting piece 11 so as to actuate the corresponding clamping spring.

Comme cela est montré à la figure 5, lorsque la pointe d'un outil d'actionnement 16 est introduite dans une ouverture d'actionnement 15, elle coopère avec une paroi du ressort de serrage correspondant 13 de manière à positionner un logement 17 ménagé à l'extrémité libre du ressort en regard avec l'ouverture de raccordement correspondante 14.As shown in FIG. 5, when the tip of an actuating tool 16 is inserted into an actuating aperture 15, it cooperates with a wall of the corresponding clamping spring 13 so as to position a housing 17 arranged at the free end of the spring opposite the corresponding connection opening 14.

Dans cette position du ressort de serrage, il est possible d'introduire un fil conducteur dans le logement 17 du ressort. Lorsque l'outil d'actionnement 16 est retiré hors du corps en matériau isolant 4, le ressort tend à reprendre sa position de repos et donc comprime le fil conducteur contre la pièce de connexion 11.In this position of the clamping spring, it is possible to introduce a conductive wire into the housing 17 of the spring. When the actuating tool 16 is removed from the body of insulating material 4, the spring tends to resume its rest position and thus compresses the conductive wire against the connection piece 11.

Comme montré sur la figure 3, une ouverture de raccordement latérale 18 est ménagée dans la face latérale 8 du corps en matériau isolant 4. Cette ouverture de raccordement 18 est située en regard d'un logement 19 de forme complémentaire ménagé dans la pièce de connexion 11.As shown in Figure 3, a lateral connection opening 18 is formed in the side face 8 of the body of insulating material 4. This connection opening 18 is located opposite a housing 19 of complementary shape in the connection piece. 11.

Comme plus particulièrement représenté aux figures 4 et 6, le logement 19 est délimité d'une part par un évidement 20 ménagé dans la pièce de connexion sensiblement au niveau de la base du U, et d'autre part par la barrette conductrice 12.As more particularly shown in FIGS. 4 and 6, the housing 19 is delimited on the one hand by a recess 20 formed in the connection piece substantially at the base of the U, and on the other hand by the conductive bar 12.

Ce logement 19 est destiné à recevoir une fiche conductrice d'un organe de liaison électrique ou d'un autre appareil électrique.This housing 19 is intended to receive a conductive plug of an electrical connection member or other electrical device.

La figure 1 représente le raccordement d'un organe de liaison électrique 21 avec l'appareil électrique 2.FIG. 1 represents the connection of an electrical connection member 21 with the electrical apparatus 2.

L'organe de liaison électrique 21 comprend un corps en matériau isolant 22 comprenant deux faces latérales opposées sensiblement parallèles, chaque face latérale du corps isolant comportant une fiche conductrice 23 présentant une forme complémentaire du logement 19 ménagé dans la pièce de connexion 11 et destinée à être insérée dans ce dernier par l'intermédiaire de l'ouverture de raccordement 18 ménagée dans la face latérale 8 du corps en matériau isolant 4.The electrical connection member 21 comprises a body of insulating material 22 comprising two substantially parallel opposite side faces, each lateral face of the insulating body comprising a conductive plug 23 having a shape complementary to the housing 19 formed in the connecting piece 11 and intended for be inserted into the latter through the connection opening 18 formed in the side face 8 of the body of insulating material 4.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cet appareil électrique, décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation. C'est ainsi notamment que le nombre de bornes de raccordement, d'ouvertures de raccordement avant et latérale, et d'ouvertures d'actionnement pourrait être différent. En outre la pièce de connexion et la barrette conductrice peuvent être réalisées en une seule pièce.As goes without saying, the invention is not limited to the sole embodiment of this electrical apparatus, described above as an example, it encompasses all the variants. In particular, the number of connection terminals, front and side connection openings, and actuating openings could be different. In addition, the connecting piece and the conductive strip may be made in one piece.
