Description

L'invention concerne le domaine technique des dispositifs de raccordement pour au moins un conducteur électrique mettant en oeuvre, pour l'immobilisation du conducteur raccordé, un ressort de connexion en boucle.The invention relates to the technical field of connection for at least one electrical conductor using, for immobilization of the connected conductor, a loop connection spring.

Dans le domaine ci-dessus, il est connu de mettre en oeuvre des blocs de jonction tels que ceux décrits par la demande DE-195 29 028 ou des blocs de raccordement pour circuits imprimés tels que décrits dans la demande DE-196 11 762, ou bien encore dans la demande DE-198 34 681.In the above field, it is known to implement terminal blocks such as those described in application DE-195 29 028 or connection blocks for printed circuits as described in the request DE-196 11 762, or even in application DE-198 34 681.

Selon ces différents documents, le dispositif de raccordement comprend un boítier isolant définissant au moins un logement de raccordement pour un conducteur électrique. Le dispositif comprend alors, dans chaque logement de raccordement :

  • une pièce d'interconnexion pourvue d'au moins une branche de raccordement,
  • un ressort de raccordement présentant une forme de boucle et comprenant successivement une branche d'appui disposée sur la branche de raccordement de la pièce d'interconnexion, un coude reliant la branche d'appui avec un dos de manoeuvre, et une branche de connexion prolongeant le dos de manoeuvre à l'opposé du coude, vers la branche d'appui et présentant une fenêtre de connexion destinée à recevoir le conducteur électrique pour le plaquer contre la pièce d'interconnexion,
les moyens de compression comprenant une came qui est adaptée dans le logement de raccordement pour être mobile en rotation entre un début de course correspondant à un état détendu du ressort et une fin de course correspondant à un état comprimé du ressort, qui est pourvue d'un levier de manoeuvre s'étendant en partie au moins à l'extérieur du boítier pour permettre une manoeuvre de la came entre le début et la fin de course et qui présente un chemin de came comprenant, d'une part, une zone, dite morte, dans laquelle la came peut pivoter à partir du début de course sans agir sur le ressort et, d'autre part, une zone, dite active, consécutive à la zone morte, dans laquelle la came assure une compression progressive du ressort au fur et à mesure de sa rotation vers la fin de course.According to these various documents, the connection device comprises an insulating housing defining at least one connection housing for an electrical conductor. The device then comprises, in each connection housing:
  • an interconnection piece provided with at least one connection branch,
  • a connection spring having a loop shape and successively comprising a support branch disposed on the connection branch of the interconnection piece, an elbow connecting the support branch with an operating back, and a connection branch extending the operating back opposite the elbow, towards the support branch and having a connection window intended to receive the electrical conductor to press it against the interconnection piece,
the compression means comprising a cam which is adapted in the connection housing to be movable in rotation between a start of travel corresponding to a relaxed state of the spring and an end of travel corresponding to a compressed state of the spring, which is provided with an operating lever extending at least partly outside the housing to allow an operation of the cam between the start and the end of the race and which has a cam path comprising, on the one hand, a zone, called dead, in which the cam can pivot from the start of the stroke without acting on the spring and, on the other hand, a zone, called active, consecutive to the dead zone, in which the cam ensures progressive compression of the spring as and as it rotates towards the end of the stroke.

De tels dispositifs donnent entière satisfaction, dans leur fonction de raccordement, électriquement fiable et mécaniquement résistant, d'un conducteur électrique. Toutefois, la conception même de la came ne permet pas d'assurer une position stable de la came, en particulier en début et fin de course.Such devices are entirely satisfactory in their function connection, electrically reliable and mechanically resistant, of a electrical conductor. However, the very design of the cam does not allow not to ensure a stable position of the cam, in particular at the beginning and end of race.

Il apparaít donc le besoin de disposer d'un nouveau type de dispositif de raccordement qui mette en oeuvre des moyens de compression du ressort qui ne nécessitent pas d'exercer un effort trop important pour comprimer le ressort et qui soient plus faciles d'utilisation que les systèmes à palonnier bistable selon l'art antérieur, tout en évitant des mouvements intempestifs de la came.It therefore appears the need to have a new type of connection device which implements means for compressing the springs that do not require exerting too much effort to compress the spring and are easier to use than bistable lifter according to the prior art, while avoiding movements untimely cam.

A cet effet, selon l'invention, le dispositif est essentiellement caractérisé en ce qu'il comprend des moyens de freinage de la rotation de la came en position de début de course et/ou de fin de course.To this end, according to the invention, the device is essentially characterized in that it comprises means for braking the rotation of the cam in start position and / or end position.

Selon une forme de réalisation préférée, le levier est situé contre le boítier lorsque la came est en début de course, le ressort étant détendu. Ainsi, la zone morte définit une partie de la course de la came pendant laquelle il est possible de déplacer la came et le levier sans effort. Cette course morte permet alors d'éloigner le levier de manoeuvre du boítier, de manière à disposer d'une prise suffisante pour pouvoir exercer, avec confort et sans risque de blessure sur le levier, l'effort nécessaire à la compression du ressort par la came.According to a preferred embodiment, the lever is located against the housing when the cam is at the start of the stroke, the spring being relaxed. So, the dead zone defines part of the cam stroke during which it is effortlessly move the cam and lever. This dead race allows then move the operating lever away from the housing, so as to have a sufficient grip to be able to exercise, with comfort and without risk of injury on the lever, the force necessary for the compression of the spring by the cam.

Selon une autre caractéristique de l'invention, le chemin de came est adapté pour que la came soit dans une position stable en tout point de la zone active. Cette disposition de l'invention dispense alors un utilisateur du dispositif d'effectuer une compression complète du ressort à chaque opération de raccordement. En effet, dans certaines situations, selon la taille du conducteur électrique à raccorder, il n'est pas toujours nécessaire de comprimer complètement le ressort pour engager le conducteur dans la fenêtre de connexion du ressort.According to another characteristic of the invention, the cam path is adapted so that the cam is in a stable position at any point of the active area. This provision of the invention then exempts a user from the device for performing complete compression of the spring at each operation connection. Indeed, in certain situations, depending on the size of the electrical conductor to be connected, it is not always necessary to fully compress the spring to engage the conductor in the window spring connection.

Selon une autre caractéristique avantageuse de l'invention, la came présente au moins un canal de test offrant un accès au ressort de raccordement. De manière préférée mais non strictement nécessaire, le canal est adapté pour assurer au moins un accès au ressort de raccordement en position détendue du ressort correspondant au début de course de la came. Ainsi, il est possible d'amener, par le canal de test, un élément conducteur d'un dispositif de mesure au contact du ressort pour, par exemple, s'assurer de la présence ou non d'une tension électrique au niveau du ressort et donc de la pièce d'interconnexion. According to another advantageous characteristic of the invention, the cam has at least one test channel providing access to the spring connection. Preferably but not strictly necessary, the channel is adapted to ensure at least access to the connection spring in relaxed position of the spring corresponding to the start of the cam stroke. Thus, it is possible to bring, via the test channel, a conductive element of a measuring device in contact with the spring to, for example, ensure the presence or not of an electric tension at the level of the spring and therefore of the interconnection piece.

Selon une autre caractéristique de l'invention, la came pivote d'un demi tour entre le début et la fin de course. Cette disposition permet, lorsque la came présente un canal de test, d'utiliser pour les mesures le même canal, que la came soit en position de début de course ou en position de fin de course.According to another characteristic of the invention, the cam pivots by U-turn between the start and the end of the race. This provision allows, when the cam presents a test channel, to use for the measurements the same channel, as the cam either in the start position or in the end position.

Selon l'invention, le boítier et la came sont reliées par une liaison pivot qui peut être réalisée de toute manière appropriée, telle que par exemple sous la forme d'un axe traversant disposé à la fois dans un alésage de la came et deux alésages complémentaires du boítier. La came pourrait également présenter un alésage central destiné à venir s'engager d'un axe solidaire du boítier. Toutefois, selon une forme de réalisation préférée de l'invention, la came comprend deux pivots latéraux destinés à être engagés dans deux paliers complémentaires du boítier. Lorsque la liaison pivot de la came avec le boítier est réalisée de cette façon, les moyens de freinage comprennent alors au moins deux conformations complémentaires, aménagées respectivement sur un pivot et le palier correspondant. Les conformations complémentaires du pivot et du palier sont alors destinées à coopérer au moins en position de début de course de la came.According to the invention, the housing and the cam are connected by a connection pivot which can be carried out in any suitable manner, such as for example in the form of a through axis arranged both in a bore of the cam and two complementary bores of the housing. The cam could also present a central bore intended to come to engage an axis integral with the housing. However, according to a preferred embodiment of the invention, the cam includes two lateral pivots intended to be engaged in two complementary bearings of the case. When the pivot connection of the cam with the housing is made in this way, the braking means then comprise at least two complementary conformations, arranged respectively on a pivot and the corresponding bearing. The complementary conformations of the pivot and bearing are then intended to cooperate at least in the start position cam travel.

Selon une autre disposition de l'invention visant à simplifier les opérations de montage et d'assemblage du dispositif de raccordement, le boítier isolant comprend deux demi-corps dits avant et arrière. Le demi-corps avant délimite alors au moins un logement de raccordement et comprend une façade de raccordement dans laquelle est aménagé au moins un passage pour le conducteur à raccorder, et à l'opposé de la façade une ouverture pour le montage de la pièce d'interconnexion et du ressort ainsi que de la came.According to another provision of the invention aimed at simplifying the assembly and assembly of the connection device, the insulating housing comprises two half-bodies called front and rear. The half body before then delimits at least one connection housing and includes a connection facade in which at least one passage is arranged for the conductor to be connected, and opposite the facade an opening for the mounting the interconnection piece and the spring as well as the cam.

Le demi-corps arrière est par ailleurs destiné à être adapté sur le demi-corps avant pour fermer le logement de raccordement et immobiliser au moins la pièce d'interconnexion, le ressort de raccordement et la came.The rear half-body is also intended to be adapted on the front half body to close the connection housing and immobilize at minus the interconnection piece, the connection spring and the cam.

Ce mode de réalisation du boítier isolant permet, de manière fort avantageuse, de mettre en place les différentes pièces constitutives du dispositif par l'arrière du boítier avant, puis de venir fermer ce dernier au moyen du demi-corps arrière qui immobilise alors les constituants du dispositif dans le boítier isolant.This embodiment of the insulating housing allows, in a strong way advantageous, to set up the various component parts of the device from the back of the front case, then close it by means of the rear half-body which then immobilizes the components of the device in the insulating housing.

Afin de faciliter encore les opérations de montage de la came, le demi-corps avant définit deux demi-paliers de réception des pivots de la came, chaque demi-palier étant ouvert vers l'arrière et comprenant une partie semi-cylindrique prolongée, à l'opposé d'un espace de réception pour le ressort, par une butée d'appui sensiblement plane et tangente à la partie cylindrique. Le demi-corps arrière définit alors deux demi-paliers complémentaires des demi-paliers du demi-corps avant pour former les deux paliers de réception des pivots de la came.To further facilitate the mounting operations of the cam, the front half-body defines two half-bearings for receiving the cam pivots, each half-bearing being open towards the rear and comprising a semi-cylindrical part extended, opposite a receiving space for the spring, by a substantially planar abutment tangent to the cylindrical part. The rear half-body then defines two complementary half-bearings of the half-bearings of the front half-body to form the two landing stages for cam pivots.

Dans le même sens, afin de permettre une mise en place de la pièce d'interconnexion dans le logement de raccordement par l'arrière du demi-boítier avant, la branche de raccordement de la pièce d'interconnexion est sensiblement plane et présente une largeur supérieure à la largeur du reste de la pièce d'interconnexion. Le boítier isolant définit alors deux butées latérales de reprise des efforts exercés sur la branche de raccordement par le ressort de raccordement lors de sa compression.In the same direction, in order to allow the establishment of the interconnection piece in the connection housing from the rear of the half-housing front, the connecting branch of the interconnection piece is substantially flat and has a width greater than the width of the rest of the interconnection piece. The insulating housing then defines two lateral stops of resumption of the forces exerted on the branch of connection by the spring of connection during compression.

Selon une forme préférée de réalisation, les butées de reprise sont formées par des ailes du demi-corps arrière destinées à venir s'engager contre la branche du raccordement lors de l'assemblage des deux demi-corps constitutifs du boítier isolant.According to a preferred embodiment, the recovery stops are formed by wings of the rear half-body intended to engage against the branch of the connection when assembling the two half-bodies components of the insulating housing.

Le dispositif de raccordement, selon l'invention, peut constituer différents types de dispositifs tels que par exemple un boítier d'interconnexion. A cet effet, la pièce d'interconnexion peut être équipée de plusieurs systèmes de raccordement à ressort ou de système de connexion d'éléments conducteurs divers.The connection device according to the invention can constitute different types of devices such as for example an interconnection box. For this purpose, the interconnection piece can be equipped with several systems spring connection or element connection system miscellaneous drivers.

Selon une forme de réalisation préférée et non strictement nécessaire, le dispositif de raccordement est destiné à permettre le raccordement rapide de conducteurs électriques tels que des câbles électriques à un circuit imprimé. La pièce d'interconnexion comprend alors un picot s'étendant à l'extérieur du boítier pour le raccordement au circuit imprimé.According to a preferred embodiment and not strictly necessary, the connection device is intended to allow the quick connection of electrical conductors such as cables electrical to a printed circuit. The interconnection piece then includes a pin extending outside the housing for connection to the printed circuit.

Selon une forme préférée de réalisation, le picot s'étend sensiblement perpendiculairement à la branche de raccordement et se trouve relié à la branche de raccordement, par une branche de liaison qui s'étend à partir de la branche de raccordement en étant tout d'abord repliée contre la branche de raccordement, puis en s'éloignant de la branche de raccordement pour définir une butée pour un câble électrique engagé dans le logement de raccordement.According to a preferred embodiment, the spike extends substantially perpendicular to the connecting branch and is located connected to the connecting branch, by a connecting branch which extends to from the connecting branch being first folded against the branch, then away from the branch to define a stop for an electric cable engaged in the housing of connection.

Selon une autre caractéristique de l'invention, le boítier comprend un canal de mesure offrant un accès à la pièce d'interconnexion.According to another characteristic of the invention, the housing comprises a measurement channel providing access to the interconnection piece.

Selon encore une autre caractéristique de l'invention, la branche de raccordement de la pièce d'interconnexion présente, à l'opposé de son extrémité libre, une fenêtre d'interconnexion et le boítier possède un canal d'interconnexion pour la mise en place d'une fiche d'interconnexion dans la fenêtre d'interconnexion.According to yet another characteristic of the invention, the branch of connection of the interconnection piece present, opposite its free end, an interconnection window and the box has a channel for the installation of an interconnection plug in the interconnection window.

Figure 12 is a perspective of an interconnection piece put used in the context of the connection device according to the invention illustrated in Figure 11.

Les figures 13 et 14 sont des coupes analogues respectivement aux figures 2 et 3 montrant une variante de réalisation d'un dispositif de raccordement conforme à l'invention.Figures 13 and 14 are similar sections respectively in Figures 2 and 3 showing an alternative embodiment of a connection according to the invention.

Un dispositif de raccordement selon l'invention, tel que désigné dans son ensemble par la référence 1 à la figure 1, comprend un boítier isolant 2 définissant au moins un et, selon l'exemple illustré, trois logements 3, 4, 5 pour le raccordement des conducteurs électriques à raison d'au moins un par logement.A connection device according to the invention, as designated as a whole by the reference 1 in Figure 1, includes an insulating housing 2 defining at least one and, according to the example illustrated, three housings 3, 4, 5 for the connection of electrical conductors at the rate of at least one per housing.

Comme le montrent les figures 2 et 3, le dispositif de raccordement 1 comprend, dans chaque logement, une pièce d'interconnexion 6 pourvue d'au moins une branche de raccordement 7. Selon l'exemple illustré, le dispositif de raccordement 1 est conçu pour être adapté sur un circuit imprimé. Ainsi, chaque pièce d'interconnexion 6 comprend un picot 8 sensiblement perpendiculaire à la branche 7 et destiné à faire saillie à l'extérieur du boítier pour venir s'insérer dans un orifice complémentaire du circuit imprimé non représenté.As shown in Figures 2 and 3, the connection device 1 includes, in each housing, an interconnection piece 6 provided at least one connecting branch 7. According to the example illustrated, the connection device 1 is designed to be adapted on a printed circuit. Thus, each interconnection piece 6 comprises a pin 8 substantially perpendicular to the branch 7 and intended to protrude outside the housing to fit into a complementary hole in the printed circuit not represented.

Le dispositif comprend également, dans chaque logement, un ressort de raccordement 9 qui présente une forme de boucle. Le ressort 9 comprend successivement une branche d'appui 10 disposée sur ou contre la branche de raccordement 7, un coude 11 reliant la branche d'appui 10 à un dos de manoeuvre 12. Le ressort 9 comprend enfin une branche de connexion 13 prolongeant le dos de manoeuvre 12 à l'opposé du coude 11 et vers la branche d'appui 10. La branche de connexion 13 présente en outre une ouverture ou fenêtre de connexion 14 destinée à recevoir un conducteur électrique 15 tel qu'illustré en trait mixte à la figure 3. De manière connue en soi, le ressort 9 est destiné à plaquer le conducteur 15 contre la pièce d'interconnexion 6 et plus particulièrement contre la face de la branche de raccordement 7 située à l'opposé de la branche d'appui 10 du ressort 9.The device also includes, in each housing, a connecting spring 9 which has a loop shape. Spring 9 successively comprises a support branch 10 disposed on or against the connection branch 7, an elbow 11 connecting the support branch 10 to a operating back 12. The spring 9 finally comprises a connection branch 13 extending the operating back 12 opposite the elbow 11 and towards the support branch 10. The connection branch 13 also has a opening or connection window 14 intended to receive a conductor electric 15 as illustrated in phantom in Figure 3. In a manner known in itself, the spring 9 is intended to press the conductor 15 against the workpiece interconnection 6 and more particularly against the face of the branch of connection 7 located opposite the support branch 10 of the spring 9.

Le dispositif de raccordement 1 comprend en outre, en relation avec chaque logement de raccordement, des moyens de compression 16 du ressort 9 pour dégager l'ouverture de connexion 14 et autoriser l'introduction du conducteur 15 comme le montre la figure 3.The connection device 1 further comprises, in relation with each connection housing, compression means 16 of the spring 9 to clear the connection opening 14 and authorize the introduction of the conductor 15 as shown in Figure 3.

Les moyens de compression 16 comprennent une came 20 qui est adaptée dans le logement de raccordement du boítier 1 pour être mobile en rotation entre une position de début de course D, telle qu'illustrée à la figure 2, dans laquelle le ressort 9 est détendu ou n'est pas sollicité par la came 20 et une position de fin de course F, telle qu'illustrée à la figure 3, dans laquelle le ressort 9 est comprimé. La came 20 est pourvue d'un levier de manoeuvre 21 qui s'étend, en partie au moins, à l'extérieur du boítier pour permettre un déplacement de la came 20 entre ses positions de début D et de fin F de course.The compression means 16 comprise a cam 20 which is adapted in the connection housing of the housing 1 to be mobile in rotation between a start position D, as illustrated in FIG. 2, in which the spring 9 is relaxed or is not stressed by the cam 20 and an end position F, as illustrated in FIG. 3, in which the spring 9 is compressed. The cam 20 is provided with an operating lever 21 which extends, at least in part, outside the housing to allow a displacement of the cam 20 between its start D and end F positions of race.

Afin de réduire autant que faire se peut l'encombrement du dispositif 1, le levier 21 est adapté sur la came 20 de manière à être plaqué contre le boítier 2 en position de début de course D, correspondant à l'état détendu du ressort 9.In order to reduce as much as possible the size of the device 1, the lever 21 is adapted on the cam 20 so as to be pressed against the housing 2 in the start-of-travel position D, corresponding to the state relaxed spring 9.

Afin de permettre un dégagement du levier 21 pour faciliter sa préhension en début de course, la came 20 présente un chemin de came 24 qui comprend, d'une part, une zone dite morte 25 dans laquelle la came 20 peut pivoter à partir du début de course D sans agir sur le ressort 9 et, d'autre part, une zone active 26 consécutive à la zone morte 25 dans laquelle la came 20 assure une compression progressive du ressort 9 au fur et à mesure de sa rotation vers la fin de course D. La zone morte 25 peut alors être le résultat soit d'un profil de came particulier, soit d'un jeu prédéterminé existant entre la came 20 et le dos 11 du ressort 9 en début de course. La présence de la zone morte 25 du chemin de came 24 présente l'avantage de permettre un dégagement du levier 21 par rapport au boítier isolant 2 sans avoir à appliquer d'effort particulier sur le levier 21 pour ensuite commander la rotation de la came 20 au moyen du levier 21.In order to allow release of the lever 21 to facilitate its gripping at the start of the stroke, the cam 20 has a cam path 24 which comprises, on the one hand, a so-called dead zone 25 in which the cam 20 can pivot from the start of stroke D without acting on the spring 9 and, on the other share, an active zone 26 consecutive to the dead zone 25 in which the cam 20 ensures progressive compression of the spring 9 as it is rotation towards the end of travel D. The dead zone 25 can then be the result either a particular cam profile, or a predetermined clearance existing between the cam 20 and the back 11 of the spring 9 at the start of the race. The presence of the dead zone 25 of the cam track 24 has the advantage of allowing clearance of the lever 21 relative to the insulating housing 2 without having to apply any force particular on the lever 21 to then control the rotation of the cam 20 at lever 21.

Selon une caractéristique préférée mais non strictement nécessaire de l'invention, le chemin de came 24 est conçu pour que la came 20 soit dans une position stable en tout point de la zone active 26. Cette disposition de l'invention permet d'assurer une compression du ressort par l'application, sur le levier 21, d'un effort progressif sans à-coup. De plus, dans la mesure où la came 20 est stable en tout point de sa course le long de la partie active 26 du chemin de came 24, il est possible de maintenir le ressort 9, en position partiellement comprimée, sans action sur le levier 21. Cette possibilité est particulièrement intéressante lorsque par exemple les dimensions du conducteur électrique à raccorder ne nécessitent pas un dégagement complet de la fenêtre de connexion 14.According to a preferred characteristic but not strictly necessary of the invention, the cam path 24 is designed so that the cam 20 is in a stable position at any point in the active area 26. This arrangement of the invention allows compression of the spring by application, on the lever 21, of a progressive effortlessly. In addition, since the cam 20 is stable at all points of its travel along the active part 26 of the cam track 24, it is possible to keep the spring 9 in position partially compressed, without action on lever 21. This possibility is particularly interesting when for example the dimensions of the electrical conductor to be connected does not require complete clearance of the connection window 14.

Selon l'invention, la came 20 et le levier 21 ainsi que la liaison pivot, entre le boítier 2 et la came 20, peuvent être réalisés de toutes façons appropriées. Toutefois, selon une forme préférée de réalisation de l'invention, la came 20 comprend deux pivots latéraux 30 s'étendant de part et d'autre de la came 20 comme le montrent les figures 4 à 6. Chaque pivot 30 présente une forme sensiblement cylindrique de révolution d'axe X-X'. Les pivots 30 de la came 20 sont alors destinés à être engagés dans deux paliers complémentaires du boítier.According to the invention, the cam 20 and the lever 21 as well as the connection pivot, between the housing 2 and the cam 20, can be made anyway appropriate. However, according to a preferred embodiment of the invention, the cam 20 comprises two lateral pivots 30 extending on either side of the cam 20 as shown in Figures 4 to 6. Each pivot 30 has a substantially cylindrical shape of revolution of axis XX '. Pivots 30 of the cam 20 are then intended to be engaged in two bearings complementary to the case.

Selon une forme préférée de réalisation du dispositif conforme à l'invention, le boítier 2 comprend deux demi-boítiers respectivement avant 35 et arrière 36 tels que plus particulièrement illustrés aux figures 6 et 7. Selon l'exemple illustré, le demi-corps avant 35, qui limite les trois logements de raccordement 3, 4 et 5, comprend une façade de raccordement 37 dans laquelle est aménagé, pour chaque logement, un passage 38 pour le conducteur à raccorder 15. Le demi-corps avant 35 présente par ailleurs, à l'opposé de la façade 37, une ouverture 39 pour le montage, dans chacun des logements 3 à 5, de la pièce d'interconnexion 6 et du ressort 9 ainsi que de la came 20. A cet égard, le demi-corps avant 35 comprend, dans les parois latérales de chacun des logements, deux demi-paliers 40 de réception des pivots 30 de la came. Selon l'exemple illustré, chaque demi-palier 40 comprend une partie semi-cylindrique 41, ouverte vers l'arrière du demi-corps 35 et prolongée, à l'opposé de l'espace de réception du ressort 9, par une butée d'appui 42 sensiblement plane et tangente à la partie semi-cylindrique 41.According to a preferred embodiment of the device according to the invention, the housing 2 comprises two half-housings respectively before 35 and rear 36 as more particularly illustrated in FIGS. 6 and 7. According to the example illustrated, the front half-body 35, which limits the three housings of connection 3, 4 and 5, includes a connection front 37 in which is fitted, for each dwelling, a passage 38 for the conductor to be connected 15. The front half-body 35 also has, at opposite of the facade 37, an opening 39 for mounting, in each of the housings 3 to 5, the interconnection piece 6 and the spring 9 as well as the cam 20. In this respect, the front half-body 35 comprises, in the walls side of each of the housings, two half-bearings 40 for receiving cam pivots 30. According to the example illustrated, each half-bearing 40 comprises a semi-cylindrical part 41, open towards the rear of the half-body 35 and extended, opposite the space for receiving the spring 9, by a stop support 42 substantially planar and tangent to the semi-cylindrical part 41.

Par ailleurs, le demi-corps arrière 36 est destiné à être adapté sur le demi-corps avant 35, de manière à fermer chaque logement de raccordement et comprend des empreintes 45, 46 pour immobilier notamment la pièce d'interconnexion 26 et le ressort 9. De plus, le demi-corps arrière 36 comprend, pour chaque logement, deux demi-paliers 47 complémentaires des demi-paliers 40 du demi-corps avant 35 pour former les deux paliers de réception des pivots de la came 20.Furthermore, the rear half-body 36 is intended to be adapted to the front half-body 35, so as to close each housing of connection and includes footprints 45, 46 for real estate in particular the interconnection piece 26 and the spring 9. In addition, the rear half-body 36 includes, for each accommodation, two half-bearings 47 complementary to the half-bearings 40 of the front half-body 35 to form the two bearings of reception of the cam pivots 20.

L'assemblage du dispositif de raccordement 1 selon l'invention s'effectue alors en plaçant les pivots 30 de la came dans les deux demi-paliers 40 du demi-corps avant 35, en disposant le ressort 9 et la pièce d'interconnexion 6 sur le demi-corps arrière 36 et puis en engageant le demi-corps arrière 36 dans le demi-corps avant 35 de manière à refermer les logements de réception 3 à 5 qui auront tous été équipés de la même manière.The assembly of the connection device 1 according to the invention is then carried out by placing the pivots 30 of the cam in the two half-bearings 40 of the front half-body 35, by arranging the spring 9 and the part interconnection 6 on the rear half-body 36 and then engaging the half-body rear 36 in the front half-body 35 so as to close the reception rooms 3 to 5 which will all have been equipped in the same way.

Selon l'invention, afin de permettre un tel montage tout en offrant une bonne résistance aux efforts de compression du ressort 9, la branche de raccordement 7 de la pièce d'interconnexion 6 est sensiblement plane et présente une largeur supérieure à celle du reste de la pièce d'interconnexion, comme le montrent les figures 8 et 9. Ainsi, la branche de raccordement comprend deux ailes latérales 50 qui sont destinées à venir en appui sur deux butées latérales 51 aménagées dans chacun des logements de raccordement du boítier isolant 2. Les butées 51 assurent alors une reprise des efforts exercés par le ressort de raccordement 9 lors de sa compression contre la branche de raccordement 7 par la came 20.According to the invention, in order to allow such mounting while providing good resistance to the compression forces of the spring 9, the branch of connection 7 of the interconnection piece 6 is substantially flat and has a width greater than that of the rest of the interconnection piece, as shown in Figures 8 and 9. Thus, the connecting branch comprises two lateral wings 50 which are intended to come to bear on two lateral stops 51 arranged in each of the connection housings of the insulating housing 2. The stops 51 then ensure a recovery of forces exerted by the connecting spring 9 during its compression against the connecting branch 7 by cam 20.

De manière préférée, les butées 51 sont formées par des ailes du demi-corps arrière 36 destinées à être engagées contre la branche de raccordement après assemblage des deux demi-corps 35, 36 constitutifs du boítier isolant 2.Preferably, the stops 51 are formed by wings of the rear half-body 36 intended to be engaged against the branch of connection after assembly of the two half-bodies 35, 36 constituting the insulating housing 2.

Par ailleurs, il doit être remarqué que dans la mesure où la came 20 possède, à partir de sa position initiale D, une course morte, la came 20 et le levier 21 sont susceptibles d'osciller librement au voisinage de cette position D sous l'effet de vibrations, par exemple. Afin d'empêcher de tels mouvements, l'invention propose, selon une caractéristique essentielle, de mettre en oeuvre, en tant que moyens de freinage, au niveau d'au moins un pivot 30 et de son palier correspondant, du moins deux conformations 53, 54 destinées à coopérer au moins en position de début de course D pour freiner les mouvements de la came 20. Selon l'exemple illustré, il est aménagé au fond des demi-paliers 40 une nervure 53, de part et d'autre de laquelle viennent se placer deux picots 54 aménagés à l'extrémité de chaque pivot 30. Ainsi, en début de rotation de la came 20, les picots 54 viennent en butée sur la nervure 53, de sorte qu'il est nécessaire d'appliquer un léger effort pour faire pivoter la came. De plus, selon l'exemple illustré, les picots 54 et les nervures 53 assurent cette même fonction de freinage en position de fin de course F.Furthermore, it should be noted that since the cam 20 has, from its initial position D, a dead stroke, the cam 20 and the lever 21 are liable to oscillate freely in the vicinity of this position D under the effect of vibrations, for example. In order to prevent such movements, the invention proposes, according to an essential characteristic, to implement, as braking means, at at least one pivot 30 and its corresponding bearing, at least two conformations 53, 54 intended for cooperate at least in the start-of-travel position D to brake the movements of the cam 20. According to the example illustrated, it is arranged at the bottom half-bearings 40 a rib 53, on either side of which come place two pins 54 arranged at the end of each pivot 30. Thus, in start of rotation of the cam 20, the pins 54 abut on the rib 53, so it is necessary to apply a slight force to rotate the cam. In addition, according to the example illustrated, the pins 54 and the ribs 53 perform the same braking function in end position F

Selon une caractéristique avantageuse de l'invention, la came 20 présente en outre un canal de test 55 permettant d'accéder au ressort 9 au moyen par exemple d'une fiche conductrice d'un dispositif de test. De plus, comme, selon l'exemple illustré, la came 20 passe de sa position de début de course D à sa position de fin de course F par une rotation d'un demi-tour, le même canal de test 55 permet d'effectuer des mesures tant en position détendue du ressort 9 qu'en position comprimée de ce dernier, comme le montrent respectivement les figures 2 et 3.According to an advantageous characteristic of the invention, the cam 20 also has a test channel 55 providing access to the spring 9 at the for example by means of a conductive plug of a test device. Moreover, as, according to the example illustrated, the cam 20 passes from its start position stroke D to its end position F by a rotation of half a turn, the same test channel 55 allows measurements to be taken both in position relaxed spring 9 in the compressed position of the latter, as the show figures 2 and 3 respectively.

Toutefois, dans la mesure où le matériau constitutif du ressort de connexion 9 ne présente pas toujours des propriétés conductrices optimales, il peut apparaítre souhaitable d'effectuer les mesures au niveau de la pièce d'interconnexion.However, insofar as the material constituting the spring of connection 9 does not always have optimal conductive properties, it may appear desirable to perform measurements at room level interconnection.

Ainsi, la figure 10 illustre une variante de réalisation du dispositif conforme à l'invention, selon laquelle le boítier isolant 2 présente un canal 56 d'accès à la pièce d'interconnexion 6, au moyen par exemple d'une fiche conductrice d'un appareil de mesure. Selon l'exemple illustré, ce canal de mesure 56 est aménagé dans le demi-corps arrière 36.Thus, Figure 10 illustrates an alternative embodiment of the device according to the invention, according to which the insulating housing 2 has a channel 56 of access to the interconnection piece 6, for example by means of a plug conductor of a measuring device. According to the example illustrated, this channel of measure 56 is fitted in the rear half-body 36.

Par ailleurs, selon l'exemple de la figure 10, le dispositif de raccordement 1 est adapté pour permettre une interconnexion entre des logements de raccordement adjacents.Furthermore, according to the example of FIG. 10, the device for connection 1 is adapted to allow interconnection between adjacent connection housings.

A cet effet, la branche de raccordement de chaque pièce d'interconnexion 6, disposée dans les logements de raccordement, présente, à l'opposé de son extrémité libre, une fenêtre d'interconnexion 57. Le boítier isolant 2 présente alors un canal d'interconnexion 58 pour la mise en place d'une fiche d'interconnexion 59 dans la fenêtre d'interconnexion, comme cela est illustré à la figure 10.For this purpose, the connecting branch of each room interconnection 6, arranged in the connection housings, present, at opposite its free end, an interconnection window 57. The housing insulator 2 then has an interconnection channel 58 for the establishment an interconnection plug 59 in the interconnection window, like this is illustrated in Figure 10.

Les figures 11 et 12 illustrent une forme particulière de réalisation du dispositif de raccordement de la figure 10 selon laquelle le picot 8 s'étend sensiblement perpendiculairement à la branche de raccordement 7 et se trouve relié à la branche de raccordement par une branche de liaison 60 qui s'étend à partir de la branche de raccordement en étant tout d'abord repliée contre la branche de raccordement 7 puis en s'éloignant de la branche de raccordement 7 pour définir, comme le montre la figure 11, une butée 61 pour un conducteur électrique engagé dans le logement de raccordement.Figures 11 and 12 illustrate a particular embodiment of the connection device of FIG. 10 according to which the pin 8 extends substantially perpendicular to the connecting branch 7 and is located connected to the connecting branch by a connecting branch 60 which extends to from the connecting branch being first folded against the connecting branch 7 then moving away from the connecting branch 7 to define, as shown in FIG. 11, a stop 61 for a conductor electric engaged in the connection housing.

Les figures 13 et 14 illustrent une autre forme de réalisation, du dispositif de raccordement conforme à l'invention, selon laquelle le levier 21 comprend des moyens 60 pour la mise en place d'un outil destiné à permettre une manoeuvre du levier 21 et de la came 20 à partir de la position de début de course D.Figures 13 and 14 illustrate another embodiment of the connection device according to the invention, according to which the lever 21 includes means 60 for the installation of a tool intended to allow an operation of the lever 21 and of the cam 20 from the start position of race D.

Selon l'exemple illustré, les moyens 60 comprennent un logement ouvert ou une rainure 61, aménagée au niveau de l'extrémité libre 62 du levier 21, de manière à être situé dans le prolongement du dos 63 du levier 21 et accessible lorsque le levier 21 est en position de début de course D.According to the example illustrated, the means 60 comprise a housing open or a groove 61, arranged at the free end 62 of the lever 21, so as to be located in the extension of the back 63 of the lever 21 and accessible when the lever 21 is in the start of travel position D.

Ainsi, il est possible d'introduire, dans le logement 61, la lame 65 d'un tournevis 66 qui forme alors un bras de levier pour faire pivoter la came 20 dans le sens de la flèche F1. Cette disposition de l'invention permet alors de disposer d'un bras de levier plus important pour amorcer la rotation de la came 20 et la compression du ressort 9.Thus, it is possible to introduce, into the housing 61, the blade 65 a screwdriver 66 which then forms a lever arm to rotate the cam 20 in the direction of arrow F1. This arrangement of the invention then makes it possible to have a larger lever arm to initiate the rotation of the cam 20 and the compression of the spring 9.

Lorsque cette compression est amorcée, il est ensuite possible de retirer le tournevis 66 et d'achever la rotation de la came 20 au moyen du seul levier 21 pour le placer en position de fin de course F telle qu'illustrée plus particulièrement à la figure 14.When this compression is initiated, it is then possible to remove the screwdriver 66 and complete the rotation of the cam 20 by means of the single lever 21 to place it in the end position F as shown more particularly in Figure 14.

Selon les exemples décrits précédemment, le dispositif de raccordement constitue un système destiné à être adapté sur un circuit imprimé. Toutefois, le dispositif de raccordement, selon l'invention, pourrait constituer un tout autre système tel que par exemple mais non exclusivement un connecteur enfichable ou encore un bloc de jonction et de raccordement.According to the examples described above, the device for connection constitutes a system intended to be adapted on a circuit printed. However, the connection device according to the invention could constitute a completely different system such as for example but not exclusively a plug connector or a terminal block and connection.

Bien entendu, l'invention n'est pas limitée aux exemples décrits ci-dessus et diverses modifications peuvent y être apportées sans sortir de son cadre.Of course, the invention is not limited to the examples described above and various modifications can be made without leaving its frame.
