Description

Système de liaison électrique avec un ressort à lames additionnel  Electrical connection system with additional leaf spring
La présente invention concerne un système de liaison électrique pour un appareil électrique tel qu'un bloc de jonction, le système comprenant un ressort à lames additionnel. The present invention relates to an electrical connection system for an electrical apparatus such as a terminal block, the system comprising an additional leaf spring.
Il est connu d'utiliser un bloc de jonction comprenant un système de liaison électrique permettant de raccorder électriquement un conducteur électrique et un rail de support.  It is known to use a terminal block comprising an electrical connection system for electrically connecting an electrical conductor and a support rail.
Ce type de bloc de jonction comprend également d'autres prises de raccordement de conducteurs électriques avec des barrettes conductrices comprises dans le corps du bloc.  This type of terminal block also comprises other electrical conductors connection plugs with conductive strips included in the body of the block.
Le nombre de prises implique une géométrie particulière du bloc de jonction pour ne pas dépasser le gabarit requis dans un coffret électrique. Notamment le dimensionnement du système de liaison électrique peut s'avérer délicat.  The number of sockets implies a particular geometry of the terminal block so as not to exceed the required size in an electrical box. In particular, the dimensioning of the electrical connection system can be difficult.
En effet, le système doit comprendre un certain nombre de pièces pour assurer un bon contact électrique entre le conducteur électrique et le rail de support.  Indeed, the system must include a number of parts to ensure good electrical contact between the electrical conductor and the support rail.
La présente invention vise à résoudre tout ou partie des inconvénients mentionnés ci-dessus.  The present invention aims to solve all or some of the disadvantages mentioned above.
A cet effet, la présente invention concerne un système de liaison électrique pour un appareil électrique tel qu'un bloc de jonction, le système de liaison électrique comprenant :  For this purpose, the present invention relates to an electrical connection system for an electrical apparatus such as a terminal block, the electrical connection system comprising:
une barrette conductrice présentant un emplacement de contact électrique agencé pour coopérer avec une portion conductrice d'un conducteur électrique en une position de liaison et une zone de coopération agencée pour coopérer avec une portion d'un rail de support en une position de coopération,  a conductive strip having an electrical contact location arranged to cooperate with a conductive portion of an electrical conductor at a connecting position and a cooperation zone arranged to cooperate with a portion of a support rail at a cooperation position,
un dispositif de serrage agencé pour maintenir la portion conductrice en position de liaison, tel qu'un ressort à lames comprenant une branche d'appui agencée pour être montée à la barrette conductrice et une branche de serrage agencée pour maintenir la portion conductrice en position de liaison,  a clamping device arranged to hold the conductive portion in the connecting position, such as a leaf spring comprising a support branch arranged to be mounted to the conductive strip and a clamping branch arranged to hold the conductive portion in the position of bond,
un dispositif de maintien agencé pour maintenir la position de coopération avec la portion du rail de support,  a holding device arranged to maintain the position of cooperation with the portion of the support rail,
le dispositif de maintien comprenant un ressort à lames additionnel pourvu d'une branche de d'appui additionnelle agencée pour être montée à la barrette conductrice et une branche de serrage additionnelle agencée pour coopérer avec la portion du rail de support en position de coopération. Cette disposition permet de concevoir un système de liaison électrique simple et fiable. En effet, le fait de disposer d'une barrette conductrice unique reliant électriquement le rail de support et le conducteur électrique permet une bonne liaison électrique tout en réduisant le nombre de pièces du système au minimum. the holding device comprising an additional leaf spring provided with an additional branch of support arranged to be mounted to the conductive bar and an additional clamping leg arranged to cooperate with the portion of the support rail in the cooperation position. This arrangement makes it possible to design a simple and reliable electrical connection system. Indeed, the fact of having a single conductive strip electrically connecting the support rail and the electrical conductor allows a good electrical connection while reducing the number of parts of the system to a minimum.
Des économies de matières peuvent être réalisées ainsi que la diminution des transformations des matériaux de bases utilisés lors de la fabrication de la barrette conductrice, du ressort à lames et du ressort à lames additionnel.  Materials savings can be realized as well as the reduction of the transformations of the base materials used in the manufacture of the conductive strip, the leaf spring and the additional leaf spring.
Selon un autre aspect de l'invention, le dispositif de serrage est un dispositif équivalent au ressort à lames, ce dispositif étant agencé pour maintenir la portion conductrice en position de liaison avec la barrette conductrice.  According to another aspect of the invention, the clamping device is a device equivalent to the leaf spring, this device being arranged to maintain the conductive portion in the connecting position with the conductive strip.
Dans ce cas, le ressort à lames additionnel peut être qualifié de ressort à lames de maintien de la portion du rail de support. En effet dans ce cas, le qualificatif « additionnel » ne s'applique plus à ce ressort à lames.  In this case, the additional leaf spring can be called a leaf spring holding the portion of the support rail. Indeed in this case, the qualifier "additional" no longer applies to this leaf spring.
Selon cet autre aspect de l'invention, le dispositif de serrage est un dispositif de serrage à vis.  According to this other aspect of the invention, the clamping device is a screw clamping device.
Selon un aspect de l'invention, le ressort à lames et le ressort à lames additionnel sont identiques. Cette disposition permet de standardiser cette pièce, ce qui réduit le nombre de références et facilite la gestion des pièces lors de la fabrication du système de liaison électrique.  According to one aspect of the invention, the leaf spring and the additional leaf spring are identical. This arrangement makes it possible to standardize this part, which reduces the number of references and facilitates the management of the parts during the manufacture of the electrical connection system.
Selon un aspect de l'invention, la barrette conductrice présente une surface de contact longitudinale sur laquelle sont ménagés l'emplacement de contact électrique et la zone de coopération.  According to one aspect of the invention, the conductive strip has a longitudinal contact surface on which are formed the electrical contact location and the cooperation zone.
Cette disposition permet de réaliser une barrette conductrice présentant une géométrie simple, telle qu'une lame longitudinale pliée. La fabrication de la barrette conductrice en est ainsi facilitée.  This arrangement makes it possible to produce a conductive strip having a simple geometry, such as a folded longitudinal strip. The manufacture of the conductive strip is thus facilitated.
Selon un aspect de l'invention, la zone de coopération s'étend au moins en partie dans le même plan que le plan d'extension de l'emplacement de contact électrique.  According to one aspect of the invention, the cooperation zone extends at least in part in the same plane as the extension plane of the electrical contact location.
Selon un autre aspect de l'invention, la zone de coopération s'étend au moins en partie dans un plan transversal au plan d'extension de l'emplacement de contact électrique.  According to another aspect of the invention, the zone of cooperation extends at least in part in a plane transverse to the extension plane of the electrical contact location.
Cette disposition permet également une implantation simple de la barrette de liaison dans le bloc de jonction et ainsi de réaliser un gain de place par rapport à une barrette à laquelle sont ajoutés des dispositifs annexes de raccordement avec le rail de support et le conducteur électrique. La portion du rail de support et la portion conductrice du conducteur électrique peuvent ainsi être disposées aisément à proximité l'une de l'autre. This arrangement also allows a simple implementation of the connecting bar in the terminal block and thus to save space with respect to a bar to which are added additional devices for connection with the support rail and the electrical conductor. The portion of the support rail and the conductive portion of the electrical conductor can thus be arranged easily close to each other.
De préférence, l'emplacement de contact électrique s'étend de manière rectiligne selon un profil engendrant au moins une rainure. Cette disposition permet un meilleur maintien en position de la portion conductrice.  Preferably, the electrical contact location extends rectilinearly in a profile generating at least one groove. This arrangement allows better holding in position of the conductive portion.
Selon un aspect de l'invention, la zone de coopération comprend une première partie et une deuxième partie, la première partie étant apte à coopérer avec une première partie complémentaire de la portion du rail de support s'étendant selon un premier plan et la deuxième partie étant apte à coopérer avec une deuxième partie complémentaire de la portion du rail de support s'étendant selon un deuxième plan transversal au premier plan.  According to one aspect of the invention, the cooperation zone comprises a first portion and a second portion, the first portion being able to cooperate with a first complementary portion of the portion of the support rail extending in a first plane and the second part being adapted to cooperate with a second complementary portion of the portion of the support rail extending in a second plane transverse to the first plane.
Cette coopération selon deux parties transversales permet un bon positionnement respectif du rail de support et du système de liaison électrique en position de coopération.  This cooperation in two transverse parts allows a good respective positioning of the support rail and the electrical connection system in the cooperation position.
Le risque de mouvement intempestif en position de coopération et donc d'interruption de contact électrique entre le rail de support et la barrette conductrice est ainsi limité.  The risk of inadvertent movement in the cooperation position and therefore of electrical contact interruption between the support rail and the conductive strip is thus limited.
Selon un aspect de l'invention, la branche d'appui s'étend dans un plan transversal au plan d'extension de la branche d'appui additionnelle.  According to one aspect of the invention, the support branch extends in a plane transverse to the extension plane of the additional support branch.
Cette disposition permet de concevoir un bloc de jonction dans lequel la direction d'insertion du conducteur électrique peut être adaptée selon les contraintes géométriques.  This arrangement makes it possible to design a terminal block in which the direction of insertion of the electrical conductor can be adapted according to the geometric constraints.
Selon un aspect de l'invention, la barrette conductrice présente une ouverture de passage pour l'insertion de la portion conductrice en position de liaison.  According to one aspect of the invention, the conductive strip has a passage opening for insertion of the conductive portion in the connecting position.
Cette disposition permet la réalisation de la barrette conductrice en une seule pièce ne présentant pas de point de faiblesse car le courant peut toujours être transmis en quantité suffisante par les deux branches latérales engendrées par l'ouverture.  This arrangement allows the realization of the conductive strip in one piece having no point of weakness because the current can always be transmitted in sufficient quantities by the two side branches generated by the opening.
Selon un aspect de l'invention, la barrette conductrice comprend une première partie et une deuxième partie, la première partie étant en regard de la deuxième partie.  According to one aspect of the invention, the conductive strip comprises a first portion and a second portion, the first portion being opposite the second portion.
Cette disposition permet de réaliser un système de liaison électrique compact. Cette disposition permet en outre d'adapter la position du ressort à lames et du ressort à lames additionnel selon les contraintes géométriques dues à la forme du bloc de jonction. Selon un aspect de l'invention, la barrette conductrice présente une forme générale en U. This arrangement allows for a compact electrical connection system. This arrangement also makes it possible to adapt the position of the leaf spring and the additional leaf spring according to the geometrical constraints due to the shape of the terminal block. According to one aspect of the invention, the conductive strip has a generally U-shaped shape.
Cette disposition permet de réaliser la barrette conductrice à partir d'une lame rectiligne qui est ensuite pliée. Cette disposition permet une économie de matière car une tôle de base découpée en lames rectilignes engendre peu de chute, c'est-à-dire de perte de matière.  This arrangement makes it possible to produce the conductive strip from a straight strip which is then folded. This arrangement allows a saving of material because a base plate cut into straight blades causes little drop, that is to say loss of material.
Selon un aspect de l'invention, la branche d'appui additionnelle s'étend dans le prolongement de la deuxième partie de la barrette conductrice, la zone de coopération étant ménagée dans la première partie de la barrette conductrice.  According to one aspect of the invention, the additional support branch extends in the extension of the second portion of the conductive strip, the cooperation zone being formed in the first part of the conductive strip.
Cette disposition permet de réaliser une pince de maintien en position de la portion du rail de support avec la zone de coopération et la branche de serrage additionnelle.  This arrangement makes it possible to produce a holding clip in position of the portion of the support rail with the zone of cooperation and the additional clamping leg.
Ainsi la portion du rail de support est maintenue en position de coopération de manière efficace.  Thus the portion of the support rail is held in cooperation position effectively.
Selon un aspect de l'invention, la barrette conductrice est constituée d'une lame conductrice pliée.  According to one aspect of the invention, the conductive strip consists of a folded conductive blade.
La fabrication de la barrette conductrice est aisée puisqu'elle est réalisée à partir d'une tôle découpée qui est ensuite pliée pour conférer à la barrette conductrice sa forme finale.  The manufacture of the conductive strip is easy since it is made from a cut sheet which is then folded to give the conductive strip its final shape.
Selon un aspect de l'invention, la barrette conductrice est constituée d'une lame conductrice.  According to one aspect of the invention, the conductive strip consists of a conductive blade.
Cette disposition facilite la fabrication de la barrette conductrice car elle provient d'une lame plane qui est ensuite transformée. La fabrication en série de cette pièce conductrice unique permet donc de gagner en temps de production et de réduire les coûts de transformation par rapport à un système comprenant plusieurs pièces conductrices.  This arrangement facilitates the manufacture of the conductive strip because it comes from a flat blade which is then transformed. The mass production of this single conductive part thus makes it possible to save production time and reduce the cost of transformation compared to a system comprising several conductive parts.
Egalement, une économie de matière est réalisée car une tôle de base peut engendrer un nombre important de lames, les chutes de matière étant réduites.  Also, a saving of material is achieved because a base plate can generate a large number of blades, falling material is reduced.
Selon un aspect de l'invention, la lame conductrice est comprise dans un contour rectangulaire.  According to one aspect of the invention, the conductive blade is included in a rectangular contour.
En effet, puisque la lame est un rectangle, il est aisé de trouver une disposition des découpes à réaliser sur la tôle de base pour minimiser les chutes et produire le plus de barrettes conductrices.  Indeed, since the blade is a rectangle, it is easy to find an arrangement of cuts to be made on the base plate to minimize falls and produce the most conductive bars.
Selon un aspect de l'invention, la barrette conductrice comprend un enfoncement adapté pour l'emboitement à force d'une partie de fixation de la branche d'appui et/ou comprend un enfoncement additionnel adapté pour remboitement à force d'une partie de fixation additionnelle de la branche d'appui additionnelle. According to one aspect of the invention, the conductive strip comprises a recess adapted for the fitting of a fixing portion of the support branch by force and / or comprises an additional recess adapted for reinforcement by means of an additional fixing part of the additional support branch.
Cette disposition permet un montage simple et fiable du ressort à lames et/ou du ressort à lames additionnel sur la barrette conductrice. La fabrication du système de liaison électrique en est ainsi simplifiée.  This arrangement allows a simple and reliable mounting of the leaf spring and / or the additional leaf spring on the conductor bar. The manufacture of the electrical connection system is thus simplified.
Selon un aspect de l'invention, l'enfoncement est réalisé par une découpe de la lame conductrice. L'enfoncement est ainsi réalisé lors de la découpe de la lame conductrice, ce qui limite le temps de fabrication.  According to one aspect of the invention, the depression is achieved by cutting the conductive blade. Depression is thus achieved during the cutting of the conductive blade, which limits the manufacturing time.
De préférence, la découpe engendre une ouverture traversante dans la barrette conductrice.  Preferably, the cut generates a through opening in the conductive strip.
La présente invention concerne également un bloc de jonction comprenant un corps isolant dans lequel est ménagé un système de liaison électrique tel que décrit précédemment.  The present invention also relates to a terminal block comprising an insulating body in which is provided an electrical connection system as described above.
Selon un aspect de l'invention, le corps isolant comprend une portion de support de la branche d'appui et/ou une portion de support additionnelle de la branche d'appui additionnelle.  According to one aspect of the invention, the insulating body comprises a support portion of the support branch and / or an additional support portion of the additional support branch.
Cette disposition permet d'assurer le blocage de la branche d'appui lors de la sollicitation de la branche de serrage et de même pour la branche d'appui additionnelle et la portion de support additionnelle.  This arrangement makes it possible to ensure the blocking of the support branch during the loading of the clamping branch and also for the additional support branch and the additional support portion.
De toute façon l'invention sera bien comprise à l'aide de la description qui suit en référence aux dessins schématiques annexés représentant, à titre d'exemple non limitatif, une forme d'exécution de ce système de liaison électrique.  In any case the invention will be better understood with the aid of the description which follows with reference to the attached schematic drawings showing, by way of non-limiting example, an embodiment of this electrical connection system.

Comme illustré aux figures 1 à 8, un appareil électrique 1 tel qu'un bloc de jonction 3 comprend un corps isolant 5 et un système de liaison électrique 7, le système de liaison électrique 7 étant ménagé dans le corps isolant 5. As illustrated in FIGS. 1 to 8, an electrical apparatus 1 such as a junction block 3 comprises an insulating body 5 and an electrical connection system 7, the electrical connection system 7 being formed in the insulating body 5.
Le bloc de jonction 3 comprend des prises 9 pour des conducteurs électriques. Deux prises 9 sont reliées par une barre de liaison 11 pour établir un contact électrique entre deux conducteurs correspondants.  The terminal block 3 includes sockets 9 for electrical conductors. Two jacks 9 are connected by a connecting rod 11 to establish an electrical contact between two corresponding conductors.
Le bloc de jonction 3 présente également une prise 9' pour un conducteur électrique 13 destiné à être connecté électriquement à un rail de support 15 sur lequel est fixé de manière amovible le bloc de jonction 3.  The terminal block 3 also has a socket 9 'for an electrical conductor 13 intended to be electrically connected to a support rail 15 on which is removably attached the terminal block 3.
Cette connexion électrique est établie par le système de liaison électrique 9 comme détaillé ci-après. Le conducteur électrique 13 présente à une extrémité une portion conductrice 13' par exemple un embout métallique.  This electrical connection is established by the electrical connection system 9 as detailed below. The electrical conductor 13 has at one end a conductive portion 13 'for example a metal tip.
L'embout métallique est agencé pour être inséré dans un canal d'insertion 17 de la prise 9' où il est maintenu en position par le système de liaison électrique 7.  The metal tip is arranged to be inserted into an insertion channel 17 of the socket 9 'where it is held in position by the electrical connection system 7.
La prise 9' comprend en outre un canal de manœuvre 19 dans lequel un utilisateur peut introduire un outil de type tournevis pour le retrait du conducteur électrique 13.  The socket 9 'further comprises an operating channel 19 in which a user can introduce a screwdriver type tool for removing the electrical conductor 13.
Comme illustré aux figures 1 à 8, le système de liaison électrique 7 comprend une barrette conductrice 21 agencée pour transmettre un courant entre la portion conductrice 13' du conducteur électrique 13 et une portion 15' du rail de support 15.  As illustrated in FIGS. 1 to 8, the electrical connection system 7 comprises a conductive strip 21 arranged to transmit a current between the conductive portion 13 'of the electrical conductor 13 and a portion 15' of the support rail 15.
Le rail de support 15 a ainsi une double fonction puisqu'il permet la fixation du bloc de jonction 3 et il est aussi utilisé pour être raccordé électriquement au conducteur électrique 16. Le système de liaison électrique 7 comprend également un dispositif de serrage 22 de type ressort à lames 23 agencé pour maintenir la portion conductrice 13' en une position de liaison avec la barrette conductrice 21 comme illustré aux figures 1, 2, 7, 8. The support rail 15 thus has a dual function since it allows the fixing of the terminal block 3 and is also used to be electrically connected to the electrical conductor 16. The electrical connection system 7 also comprises a clamping device 22 of leaf spring type 23 arranged to hold the conductive portion 13 'at a position of connection with the conductive strip 21 as illustrated in FIGS. 1, 2, 7, 8.
Selon d'autres alternatives non détaillées, tout autre type de dispositif de serrage 22 pourrait être utilisé pourvu que le dispositif de serrage 22 soit agencé pour maintenir la portion conductrice 13' en une position de liaison avec la barrette conductrice 21. Un dispositif de serrage 22 à vis pourrait par exemple être utilisé.  According to other non-detailed alternatives, any other type of clamping device 22 could be used provided that the clamping device 22 is arranged to hold the conductive portion 13 'in a position of connection with the conductive bar 21. A clamping device 22 to screw could for example be used.
Le ressort à lames 23 comprend une branche d'appui 23' agencée pour être montée à la barrette conductrice 21. Pour ce faire la barrette conductrice 21 présente un enfoncement 25 ou une ouverture traversante issue d'une découpe adaptée pour l'emboitement à force d'une partie de fixation 27 de la branche d'appui 23'.  The leaf spring 23 comprises a bearing branch 23 'arranged to be mounted on the conductive bar 21. To do this, the conductive strip 21 has a recess 25 or a through opening resulting from a cutout adapted for the interlocking force. a fixing portion 27 of the support branch 23 '.
Le ressort à lames 23 comprend également un branche de serrage 23" jointe part une articulation 23"' à la branche d'appui 23'. La branche de serrage 23" est agencée pour maintenir la portion conductrice 13' en position de liaison.  The leaf spring 23 also comprises a clamping leg 23 "joined by a joint 23" 'to the support leg 23'. The clamping leg 23 "is arranged to hold the conductive portion 13 'in the connecting position.
En effet la branche d'appui 23' est fixe par rapport à la barrette conductrice 21 et l'articulation 23"' impose une contrainte sur la portion conductrice 13' par l'intermédiaire de la branche de serrage 23".  Indeed the support branch 23 'is fixed relative to the conductive bar 21 and the hinge 23 "' imposes a stress on the conductive portion 13 'via the clamping leg 23".
Le canal de manœuvre 19 est disposé de manière à permettre le déplacement de la branche de serrage 23" pour le retrait du conducteur électrique 13.  The maneuvering channel 19 is arranged so as to allow the displacement of the clamping branch 23 "for the withdrawal of the electrical conductor 13.
Le corps isolant 5 présente une portion de support 29 de la branche d'appui 23' ayant pour fonction de bloquer la branche d'appui 23' lors du déplacement de la branche de serrage 23".  The insulating body 5 has a support portion 29 of the support branch 23 'whose function is to block the support arm 23' during the movement of the clamping branch 23 ".
La barrette conductrice 21 présente une portion extrême pliée 31 engendrant une première partie 33' d'une zone de coopération 35 ou avancée de coopération 33 et une deuxième partie 37' de la zone de coopération 35 ou butée de coopération 37.  The conductive strip 21 has a folded end portion 31 generating a first portion 33 'of a cooperation zone 35 or advanced cooperation 33 and a second portion 37' of the cooperation zone 35 or stop cooperation 37.
Cette première partie 33' de la barrette conductrice 21 est agencée pour coopérer avec une première partie complémentaire 39 du rail de support 15 s'étendant selon un premier plan 39'.  This first portion 33 'of the conductive strip 21 is arranged to cooperate with a first complementary portion 39 of the support rail 15 extending in a first plane 39'.
Cette deuxième partie 37' de la barrette de conductrice 21 est agencée pour coopérer avec une deuxième partie complémentaire 41 du rail de support 15 s'étendant selon un deuxième plan 4 transversal au premier plan 39'. La barrette conductrice 21 présente également une surface de contact longitudinale 43 sur lequel sont ménagés un emplacement de contact électrique 45 avec la portion conductrice 13' en position de liaison, l'avancée de coopération 33 et la butée de coopération 37. This second portion 37 'of the conductor bar 21 is arranged to cooperate with a second complementary portion 41 of the support rail 15 extending along a second plane 4 transverse to the first plane 39'. The conductive strip 21 also has a longitudinal contact surface 43 on which are formed an electrical contact location 45 with the conductive portion 13 'in the connection position, the cooperation advance 33 and the cooperation stop 37.
L'emplacement de contact électrique 45 s'étend de manière rectiligne selon un profil engendrant une ou plusieurs rainures pour un meilleur maintien de la portion conductrice 13' en position de liaison.  The electrical contact location 45 extends rectilinearly in a profile generating one or more grooves for better maintenance of the conductive portion 13 'in the connecting position.
La barrette conductrice 21 présente en outre une ouverture de passage 47 pour l'insertion de la portion conductrice 13' en position de liaison. Cette ouverture de passage 47 résulte par exemple d'une découpe effectuée avant pliage de la barrette conductrice 21.  The conductive strip 21 further has a passage opening 47 for the insertion of the conductive portion 13 'in the connecting position. This passage opening 47 results for example from a cut made before folding of the conductive bar 21.
Le système de liaison électrique 7 comprend également un dispositif de maintien 49 agencé pour maintenir le rail de support 15 en une position de coopération avec la barrette conductrice 21.  The electrical connection system 7 also comprises a holding device 49 arranged to hold the support rail 15 in a position of cooperation with the conductive bar 21.
La coopération se fait par contact, ce qui permet une transmission du courant entre la barrette conductrice 21 et le rail de support 15.  The cooperation is by contact, which allows a current transmission between the conductive strip 21 and the support rail 15.
La barrette conductrice 21 comprend une première partie 51 et une deuxième partie 53 au moins partiellement en regard de la première partie 51.  The conductive strip 21 comprises a first part 51 and a second part 53 at least partially opposite the first part 51.
La première partie 51 comprend la surface de contact longitudinale 43 et la deuxième partie 53 coopère avec le dispositif de maintien 49. Le fait de disposer de ces deux parties 51, 53 permet de réaliser un système de liaison électrique 7 compact et/ou de s'adapter à des contraintes géométriques imposées au bloc de jonction 3.  The first part 51 comprises the longitudinal contact surface 43 and the second part 53 cooperates with the holding device 49. Having these two parts 51, 53 makes it possible to produce a compact electrical connection system 7 and / or to adapt to geometrical constraints imposed on the terminal block 3.
La barrette conductrice 21 peut ainsi être obtenue par une découpe dans une tôle de base puis par pliage.  The conductive strip 21 can thus be obtained by cutting in a base plate and then by folding.
Comme illustré aux figures 1 à 6, la barrette conductrice peut présenter une forme générale en U. La première partie 51 la deuxième partie 53 sont chacune ménagée dans une branche différente du U.  As illustrated in FIGS. 1 to 6, the conductive strip may have a generally U-shaped shape. The first part 51 and the second part 53 are each formed in a different branch of the U.
La forme générale en U de la barrette conductrice 21 est obtenue à partir d'une lame conductrice découpée dans une tôle de base. La lame est comprise dans un contour rectangulaire ce qui permet une économie de matière en limitant les chutes lors de la découpe. Lors de la découpe les ouvertures traversantes sont aussi créées.  The general U shape of the conductive strip 21 is obtained from a conductive strip cut from a base plate. The blade is included in a rectangular contour which allows a saving of material by limiting the falls during cutting. When cutting through openings are also created.
Alternativement, il est possible comme illustré aux figures 7 et 8 de prévoir une barrette conductrice 21 avant pliage comprenant plusieurs portions transversales reliées les unes aux autres pour engendrer une liaison latérale 55 après pliage. Cette disposition permet de maintenir une section importante pour une bonne transmission du courant une fois la barrette conductrice 21 pliée. La barrette conductrice 21 une fois pliée présente également une bonne solidité et ne risque pas d'être déformée lors du montage dans le bloc de jonction 3. Alternatively, it is possible as illustrated in Figures 7 and 8 to provide a conductive strip 21 before folding comprising a plurality of transverse portions connected to each other to generate a lateral connection 55 after folding. This arrangement makes it possible to maintain a large section for good power transmission once the conductive strip 21 is folded. The conductive strip 21 when folded also has good strength and is not likely to be deformed during assembly in the terminal block 3.
Le dispositif de maintien comprend un ressort à lames additionnel 57. Ce ressort à lames additionnel 57 peut être similaire au ressort à lames maintenant la portion conductrice 13' en position de liaison.  The holding device comprises an additional leaf spring 57. This additional leaf spring 57 may be similar to the leaf spring maintaining the conductive portion 13 'in the connecting position.
Cette disposition permet une standardisation de cette pièce et l'utilisation d'une référence en moins pour la gestion de pièces par le fabricant, le dispositif de maintien 49 étant identique au ressort à lames 23.  This arrangement allows a standardization of this part and the use of a reference less for the management of parts by the manufacturer, the holding device 49 being identical to the leaf spring 23.
Le ressort à lames additionnel 57 comprend une branche d'appui additionnelle 57' pourvue d'une partie de fixation additionnelle 60 agencée pour être fixée à un enfoncement additionnel 59 de la barrette conductrice 21 de manière similaire au ressort à lames 23 de la portion conductrice 13'.  The additional leaf spring 57 comprises an additional support leg 57 'provided with an additional attachment portion 60 arranged to be attached to an additional depression 59 of the conductive bar 21 in a manner similar to the leaf spring 23 of the conductive portion. 13 '.
La branche d'appui 57' s'étend dans le prolongement de la deuxième partie 53 de la barrette conductrice 21. Cette disposition permet également de réduire la taille et donc la matière nécessaire à la fabrication de la barrette conductrice 21.  The support leg 57 'extends in the extension of the second portion 53 of the conductive bar 21. This arrangement also reduces the size and therefore the material required for the manufacture of the conductive bar 21.
Le ressort à lames additionnel 57 comprend également une branche de serrage additionnelle 57" agencée pour coopérer avec la portion 15' du rail de support 15 en position de coopération.  The additional leaf spring 57 also comprises an additional clamping leg 57 "arranged to cooperate with the portion 15 'of the support rail 15 in the cooperation position.
De la même manière que le ressort à lames 23, le ressort à lames additionnel 57 comprend une articulation 57"'. Ainsi la branche de serrage additionnelle 57" maintien la portion 15' du rail de support 15 en position de coopération.  In the same way as the leaf spring 23, the additional leaf spring 57 comprises a hinge 57 "'Thus the additional clamping leg 57" holds the portion 15' of the support rail 15 in the cooperation position.
Le système de liaison électrique 7 obtenu comprend donc peu de pièces, est compact et est apte à respecter des contraintes géométriques de manque de place pour son intégration dans le bloc de jonction.  The electrical connection system 7 obtained therefore has few parts, is compact and is able to meet geometric constraints of space for its integration in the terminal block.
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce système de liaison électrique, décrit ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation.  As goes without saying, the invention is not limited to the sole embodiment of this electrical connection system, described above as an example, it encompasses all the variants.
