Description

La présente invention concerne un dispositif de serrage de conducteur destiné à équiper une borne de serrage d'appareil basse tension.The present invention relates to a conductor clamping device for equipping a low voltage device clamping terminal.

Afin de réaliser le contact électrique entre l'extrémité d'un conducteur électrique et un élément conducteur d'un appareil basse tension, et en particulier avec la barrette de liaison d'un bloc de jonction, il est connu d'utiliser des bornes de raccordement par serrage. Le document US-A-2002/155750 divulgue les caractéristiques du préambule de la revendication 1.In order to make the electrical contact between the end of an electrical conductor and a conductive element of a low-voltage device, and in particular with the connecting strip of a terminal block, it is known to use terminals of clamping connection. The document US-2002/155750 discloses the features of the preamble of claim 1.

Il est en particulier avantageux de réaliser des bornes de serrage dans laquelle un conducteur peut être introduit en vue d'un raccordement, sans nécessité d'utiliser un outil pour écarter un ressort de serrage.In particular, it is advantageous to provide clamping terminals in which a conductor can be inserted for connection, without the need to use a tool to move a clamping spring.

Pour enlever le conducteur de la borne de serrage, un outil est en général utilisé pour écarter le ressort de serrage.To remove the conductor from the clamping terminal, a tool is usually used to move the clamping spring away.

La raideur du ressort de serrage élastique doit être adaptée pour permettre à la fois de maintenir le conducteur au contact de la barrette de liaison et d'introduire le conducteur à l'encontre de la force élastique.The stiffness of the resilient clamping spring must be adapted to both keep the conductor in contact with the connecting bar and introduce the conductor against the elastic force.

Il est connu d'utiliser une borne de serrage comportant un dispositif dans lequel la barrette est fixée ou maintenue en position par serrage, le dispositif comprenant plusieurs éléments constitutifs différents sont utilisés, notamment des éléments constitutifs d'une cage de logement du conducteur et un ressort.It is known to use a clamping terminal comprising a device in which the bar is fixed or held in position by clamping, the device comprising several different constituent elements are used, in particular elements constituting a driver's accommodation cage and a spring.

Cette multiplicité d'éléments complique le montage d'une telle borne, ainsi que sa fabrication.This multiplicity of elements complicates the assembly of such a terminal, as well as its manufacture.

D'autre part, la largeur de l'organe élastique est contrainte par les dimensions de la cage. En conséquence, il est nécessaire, pour obtenir la raideur souhaitée du ressort dans un encombrement acceptable, d'utiliser des matériaux différents pour l'organe élastique et pour la cage.On the other hand, the width of the elastic member is constrained by the dimensions of the cage. Consequently, it is necessary to obtain the desired stiffness of the spring in an acceptable space, to use different materials for the elastic member and for the cage.

Dans le cas où il est choisi de réaliser l'ensemble du dispositif d'une seule pièce, le ressort ne peut pas présenter la raideur souhaitée.In the case where it is chosen to make the entire device in one piece, the spring can not have the desired stiffness.

La présente invention a pour objet de fournir un dispositif de serrage pour une borne de serrage dont le montage et la fabrication sont simplifiés, tout en permettant d'obtenir les caractéristiques de raideur recherchées.The present invention aims to provide a clamping device for a clamping terminal whose assembly and manufacture are simplified, while providing the desired stiffness characteristics.

A cet effet la présente invention a pour objet un dispositif de serrage pour une borne de raccordement par serrage d'un fil conducteur à une barrette de liaison conductrice, comprenant :

  • une partie formant un logement de conducteur, comprenant au moins une ouverture vers le haut destinée à recevoir au moins un fil conducteur à raccorder, ainsi que la barrette de liaison conductrice,
  • un ressort de serrage destiné à maintenir en position le fil conducteur introduit dans la partie formant logement contre la barrette de liaison en appliquant une force élastique, le ressort de serrage comportant une première branche de liaison formée par un prolongement d'une partie d'une paroi délimitant la partie formant logement, reliée par un coude à une seconde branche de serrage présentant une extrémité libre de serrage,
caractérisé en ce que le coude entre la première branche de liaison et la seconde branche de serrage est situé au moins en partie du côté opposé à l'ouverture du logement, par rapport au plan de la partie d'une paroi délimitant la partie formant logement dont la première branche de liaison forme le prolongement,
et en ce que l'ouverture destinée à recevoir au moins un fil conducteur est située du coté opposé de la partie de paroi délimitant la partie formant logement, par rapport à la branche de serrage.To this end, the subject of the present invention is a clamping device for a connection terminal by clamping a conductive wire to a conductive connection bar, comprising:
  • a portion forming a conductor housing, comprising at least one upward opening for receiving at least one conductive wire to be connected, and the conductive connecting bar,
  • a clamping spring for holding in position the lead wire introduced into the housing portion against the link bar by applying an elastic force, the clamping spring having a first connecting leg formed by an extension of a portion of a wall defining the housing portion, connected by a bend to a second clamping branch having a clamping free end,
characterized in that the bend between the first connecting leg and the second clamping leg is situated at least partly on the opposite side to the opening of the housing, relative to the plane of the part of a wall delimiting the housing part. whose first link is the extension,
and in that the opening for receiving at least one conductive wire is located on the opposite side of the wall portion defining the housing portion relative to the clamping leg.

Ces dispositions permettent de réaliser une fabrication et un montage simple. D'autre part, le ressort s'étendant pour partie à l'extérieur de la partie de logement n'est pas contraint par les dimensions de celle-ci. La disposition en arrière de l'ouverture permet d'obtenir une meilleure raideur du ressort.These arrangements allow for simple manufacturing and assembly. On the other hand, the spring extending partly outside the housing portion is not constrained by the dimensions thereof. The disposition behind the opening makes it possible to obtain a better stiffness of the spring.

Selon un mode de réalisation, la partie formant logement comporte une cage de logement comportant une paroi latérale délimitant au moins une ouverture vers le haut.According to one embodiment, the housing portion comprises a housing housing having a side wall defining at least one opening upwards.

Avantageusement, la partie de logement comporte une portion d'appui située dans le prolongement d'une seconde partie de paroi de la cage opposée à la première partie de paroi dont le prolongement forme le ressort de serrage.Advantageously, the housing portion comprises a bearing portion located in the extension of a second wall portion of the cage opposite to the first wall portion whose extension forms the clamping spring.

Selon un mode de réalisation, une ouverture est ménagée dans la portion d'appui.According to one embodiment, an opening is formed in the support portion.

Avantageusement, l'extrémité libre de la branche de serrage du ressort de serrage est située dans l'ouverture en position de repos du ressort.Advantageously, the free end of the tightening leg of the clamping spring is located in the opening in the rest position of the spring.

Selon un mode de réalisation, le ressort de serrage comporte au moins une portion présentant une largeur supérieure à celle de la cage.According to one embodiment, the clamping spring comprises at least one portion having a width greater than that of the cage.

Avantageusement, le ressort comporte au moins deux portions de largeurs différentes.Advantageously, the spring comprises at least two portions of different widths.

Selon un mode de réalisation, le dispositif est formé d'une seule pièce, par pliage.According to one embodiment, the device is formed in one piece, by folding.

Avantageusement, le dispositif est réalisé à partir d'un matériau découpé comprenant une première bande destinée à former la partie de logement et une deuxième partie sensiblement transversale à la première destinée à former le ressort par cintrage et pliage.Advantageously, the device is made from a cut material comprising a first strip intended to form the housing portion and a second portion substantially transverse to the first intended to form the spring by bending and folding.

Selon un mode de réalisation, une cage est formée par le pliage d'une bande de matériau présentant deux portions de formes complémentaires destinées à être logées l'une dans l'autre.According to one embodiment, a cage is formed by folding a strip of material having two portions of complementary shapes intended to be housed one inside the other.

La présente invention a également pour objet un appareil basse tension comportant un dispositif de serrage tel que décrit ci-dessus.The present invention also relates to a low voltage device comprising a clamping device as described above.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif, un mode de réalisation d'un dispositif selon l'invention.In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing, representing by way of nonlimiting example, an embodiment of a device according to the invention.

La figure 6 est une vue en perspective du dispositif de figure 1 et d'une partie d'appareil basse tension destinée à l'accueillir.The figure 6 is a perspective view of the device figure 1 and a portion of low voltage apparatus for accommodating it.

Selon un mode de réalisation représenté sur les figures 1 à 6, un dispositif de serrage 2 pour une borne de raccordement par serrage d'un fil conducteur à une barrette de liaison conductrice 4, comprend une partie formant logement 5 destinée à recevoir le conducteur à raccorder comportant :

  • une cage 6 comportant une paroi latérale de section sensiblement rectangulaire ouverte vers le haut,
  • une portion d'appui 7 dépassant de la cage, dans le prolongement de celle-ci.
According to an embodiment shown on the Figures 1 to 6 , a clamping device 2 for a connection terminal by clamping a conductive wire to a conductive connection strip 4, comprises a housing portion 5 intended to receive the conductor to be connected, comprising:
  • a cage 6 having a lateral wall of substantially rectangular section open upwards,
  • a bearing portion 7 protruding from the cage, in the extension thereof.

La portion d'appui comprend :

  • une première face dans le prolongement d'une première face plane d'appui 8 de la cage 6, et
  • deux parois latérales constituant un prolongement partiel de deux faces latérales adjacentes 9, 10 à la première face plane 8.
The support portion includes:
  • a first face in the extension of a first flat bearing face 8 of the cage 6, and
  • two side walls constituting a partial extension of two adjacent lateral faces 9, 10 to the first plane face 8.

La partie formant logement 5 est destinée à recevoir également la barrette de liaison 4, qui est disposée contre la première face plane d'appui 8 de la paroi 6 de la partie de logement 5.The housing portion 5 is also intended to receive the connecting bar 4, which is arranged against the first flat bearing face 8 of the wall 6 of the housing part 5.

Une ouverture 12 est ménagée dans la face d'appui 8 au niveau de la portion d'appui 7.An opening 12 is formed in the bearing face 8 at the level of the bearing portion 7.

Le dispositif comporte également un ressort de serrage 13 destiné à maintenir en position à l'encontre de sa force élastique un conducteur introduit dans la partie de logement 5.The device also comprises a clamping spring 13 intended to maintain in position against its elastic force a conductor introduced into the housing part 5.

Le ressort de serrage 13 est constitué par un prolongement d'une seconde face plane 14 de la paroi de la partie de logement 5, située à l'opposé de la première face plane 8.The clamping spring 13 is constituted by an extension of a second plane face 14 of the wall of the housing part 5, located opposite the first planar face 8.

Ce ressort de serrage 13 comporte :

  • une première branche de liaison 15 reliée par une première extrémité à la seconde face 14 de la partie de logement 5, formant le prolongement de celle-ci,
  • un coude 16, relié à la seconde extrémité de la première branche de liaison 15, et
  • une seconde branche de serrage 17, reliée au coude 16 par sa première extrémité et présentant une seconde extrémité libre 18 de serrage.
This clamping spring 13 comprises:
  • a first connecting branch 15 connected by a first end to the second face 14 of the housing part 5, forming the extension thereof,
  • a bend 16 connected to the second end of the first connecting branch 15, and
  • a second clamping branch 17, connected to the bend 16 at its first end and having a second free end 18 for clamping.

Le coude 16 entre la première branche de liaison et la seconde branche de serrage est situé du côté opposé à l'ouverture du logement, par rapport au plan A de la seconde face plane 14.The bend 16 between the first connecting branch and the second clamping branch is located on the opposite side to the opening of the housing, with respect to the plane A of the second plane face 14.

L'ouverture de la partie formant logement 5 vers le haut, destinée à recevoir au moins un fil conducteur, est située du côté opposé de la seconde face 14, par rapport à la branche de serrage 17.The opening of the housing portion 5 upwards, intended to receive at least one conductive wire, is located on the opposite side of the second face 14, with respect to the clamping branch 17.

L'extrémité de serrage 18 est destinée à maintenir en position un conducteur introduit dans la partie de logement 5 contre la barrette de liaison 4.The clamping end 18 is intended to hold in position a conductor inserted into the housing part 5 against the connecting bar 4.

Cette disposition permet d'augmenter la précontrainte du ressort par rapport à la position occupée lorsque la barrette est en position dans le logement, l'inclinaison de la branche de serrage du ressort par rapport à la barrette servant de surface d'appui étant augmentée.This arrangement makes it possible to increase the prestressing of the spring with respect to the position occupied when the bar is in position in the housing, the inclination of the clamping leg of the spring relative to the bar serving as a bearing surface being increased.

Ainsi, la raideur du ressort est augmentée.Thus, the stiffness of the spring is increased.

L'extrémité de serrage 18 du ressort est située en position de repos du ressort dans l'ouverture 12 de la portion d'appui 7.The clamping end 18 of the spring is located in the rest position of the spring in the opening 12 of the bearing portion 7.

Cette disposition permet également d'augmenter la raideur du ressort.This arrangement also increases the stiffness of the spring.

Il est à signaler également que le ressort de serrage comporte un bossage 19 dirigé vers l'extérieur du ressort 13, et permettant de former une butée pour le tournevis ou autre outil destiné à repousser le ressort en vue de ressortir le conducteur raccordé grâce au dispositif 2.It should also be noted that the clamping spring comprises a boss 19 directed towards the outside of the spring 13, and making it possible to form a stop for the screwdriver or other tool intended to push the spring in order to pull out the connected conductor thanks to the device 2.

La branche de serrage 17 du ressort comporte deux portions 20 et 22 séparées par le bossage 19, la seconde portion 22 située à proximité de l'extrémité 18 présentant sur sa partie terminale une largeur restreinte permettant de loger l'extrémité de serrage 18 entre les faces latérales 9, 10 de la portion d'appui 7.The clamping branch 17 of the spring comprises two portions 20 and 22 separated by the boss 19, the second portion 22 located near the end 18 having on its end portion a restricted width for accommodating the clamping end 18 between the side faces 9, 10 of the bearing portion 7.

La disposition selon laquelle le ressort est formé dans le prolongement d'une face de la partie de logement, et ainsi selon laquelle le ressort, à l'exception de la partie terminale, est située à l'extérieure de la partie de logement, permet de réaliser un ressort dont la largeur est plus importante, car celle-ci n'est pas limitée par la largeur de la partie de logement. Il est ainsi possible facilement d'obtenir la raideur voulue pour le ressort, sans utiliser un matériau spécifique.The provision that the spring is formed in the extension of a face of the housing portion, and thus that the spring, with the exception of the end portion, is located outside the housing portion, allows to make a spring whose width is greater, because it is not limited by the width of the housing portion. It is thus easily possible to obtain the desired stiffness for the spring, without using a specific material.

Des rétrécissements 23, 24 situés à la base de la branche de liaison, au niveau de la liaison avec la seconde face plane de la partie de logement, permettent de s'affranchir de contraintes de pliage du matériau.Narrowing 23, 24 located at the base of the connecting branch, at the level of the connection with the second planar face of the housing portion, make it possible to overcome the folding constraints of the material.

Ainsi que représenté sur la figure 5, le dispositif 2 est réalisé d'une seule pièce à partir d'un matériau en forme de plaque. La portion constituant la cage est formée d'une bande 25 comportant à chacune de ses extrémités respectivement une patte en forme de trapèze 26 et un logement de forme complémentaire 27, afin de pouvoir constituer, par pliage, une fermeture par complémentarité de forme.As shown on the figure 5 , the device 2 is made in one piece from a plate-shaped material. The portion constituting the cage is formed of a strip 25 having at each of its ends respectively a trapezoid-shaped lug 26 and a complementary shaped housing 27, in order to be able to constitute, by folding, a closure by complementary shape.

On distingue également les parties destinées à former la portion d'appui 7 et le ressort de serrage 9, formant des prolongements latéraux de la bande 25.There are also the parts intended to form the bearing portion 7 and the clamping spring 9, forming lateral extensions of the band 25.

La figure 6 représente une partie du corps isolant d'un appareil basse tension 28, comportant un logement 29 destiné à recevoir un dispositif 2, ainsi qu'une barrette de liaison 4.The figure 6 represents a part of the insulating body of a low voltage device 28, comprising a housing 29 intended to receive a device 2, as well as a connecting bar 4.

Le corps de l'appareil comporte une ouverture d'introduction de conducteur 30 et une ouverture 32 d'introduction d'un outil 33, utilisé pour retirer le conducteur de la borne ainsi formée.The body of the apparatus comprises a conductor insertion opening 30 and an insertion opening 32 of a tool 33, used to remove the conductor from the terminal thus formed.

Comme il va se soi, l'invention ne se limite pas à la forme de réalisation préférentielle décrite ci-dessus, à titre d'exemples non limitatif ; elle en embrasse au contraire toutes les variantes dans le cadre des revendications ci-après.As is self-evident, the invention is not limited to the preferred embodiment described above, by way of non-limiting examples; it encompasses all the variants in the context of the claims below.
