Description

La présente invention concerne le domaine du raccordement d'appareils électriques basses tension et a plus particulièrement pour objet un connecteur débrochable pour blocs de jonction.The present invention relates to the field of connection of low-voltage electrical appliances and more particularly to a plug-in connector for terminal blocks.

Un connecteur débrochable pour bloc de jonction assure la connexion électrique entre un fil électrique conducteur et une prise du bloc de jonction reliée à une première portion de connexion.A withdrawable connector for a terminal block provides the electrical connection between a conductive electrical wire and a plug of the terminal block connected to a first connection portion.

Un connecteur débrochable peut ainsi être remplacé sur un bloc de jonction en fonction des caractéristiques du conducteur électrique à connecter, notamment en fonction de son diamètre.A plug-in connector can thus be replaced on a terminal block according to the characteristics of the electrical conductor to be connected, in particular according to its diameter.

Ainsi, il est connu de disposer d'un connecteur débrochable pour bloc de jonction comprenant :

  • un corps isolant,
  • une borne de connexion présentant un logement pour un fil électrique conducteur destiné à être inséré au travers une première ouverture du corps isolant selon une direction d'insertion du fil électrique conducteur dans le corps isolant, et
  • une prise de connexion comprenant une embase à partir de laquelle s'étendent deux branches élastiques de connexion destinées à assurer un contact électrique avec une prise complémentaire du bloc de jonction destinée à traverser une deuxième ouverture du corps isolant.
Thus, it is known to have a withdrawable connector for a terminal block comprising:
  • an insulating body,
  • a connection terminal having a housing for a conductive electrical wire for insertion through a first opening of the insulating body in a direction of insertion of the conductive electrical wire into the insulating body, and
  • a connection socket comprising a base from which extend two elastic connection branches intended to ensure electrical contact with a complementary terminal of the terminal block for passing through a second opening of the insulating body.

Cependant, la borne de connexion et la prise de connexion sont agencées dans le corps isolant du connecteur débrochable de façon indépendante.However, the connection terminal and the connection socket are arranged in the insulating body of the withdrawable connector independently.

En effet, la borne de connexion a uniquement pour fonction de créer un lien électrique avec le fil électrique conducteur.Indeed, the connection terminal is solely for the purpose of creating an electrical connection with the conductive electrical wire.

La prise de connexion a quant à elle uniquement pour fonction de créer un lien électrique avec la prise complémentaire du bloc de jonction.The connection socket only has the function of creating an electrical connection with the complementary socket of the terminal block.

La prise de connexion n'a aucune interaction mécanique avec le fil électrique conducteur qui reste à distance de celle-ci.The connection socket has no mechanical interaction with the conductive electrical wire which remains at a distance from it.

En outre, la borne de connexion exerce une pression de serrage sur une portion du fil électrique conducteur située à distance de son extrémité libre.In addition, the connection terminal exerts a clamping pressure on a portion of the conductive electrical wire located at a distance from its free end.

Par conséquent, le corps isolant comprend un logement spécifique pour recevoir cette extrémité du fil électrique conducteur ayant traversé la borne de connexion.Therefore, the insulating body includes a specific housing for receiving this end of the conductive electrical wire having passed through the connection terminal.

La présence de ce logement spécifique dans le corps isolant induit un dimensionnement minimal des dimensions du connecteur débrochable, en particulier de sa hauteur.The presence of this specific housing in the insulating body induces a minimum dimensioning of the dimensions of the plug-in connector, in particular its height.

Typiquement, un connecteur débrochable de l'état de la technique présente un encombrement hors tout d'au moins 40 mm.Typically, a plug-in connector of the state of the art has an overall footprint of at least 40 mm.

Dans certains cas, l'encombrement des connecteurs débrochables empêche l'insertion d'une rangée supplémentaire de blocs de connexion dans une armoire ou un coffret électrique.In some cases, the size of the withdrawable connectors prevents the insertion of an additional row of connection blocks in a cabinet or an electrical box.

DE 10 2004 045025 B3 divulgue les caractéristiques du préambule de la revendication 1. La présente invention a pour but de résoudre tout ou partie des inconvénients mentionnés ci-dessus. DE 10 2004 045025 B3 discloses the features of the preamble of claim 1. The present invention aims to solve all or part of the disadvantages mentioned above.

A cet effet, la présente invention a pour objet un connecteur débrochable tel que décrit précédemment caractérisé en ce qu'il comprend un passage pour le fil électrique conducteur reliant le premier logement de la borne de connexion et un deuxième logement formé dans l'embase de la prise de connexion.For this purpose, the present invention relates to a withdrawable connector as described above characterized in that it comprises a passage for the conductive electrical wire connecting the first housing of the connection terminal and a second housing formed in the base of the connection socket.

Cette disposition permet de réduire l'encombrement du connecteur débrochable en affectant à l'embase de la prise de connexion la double fonction de maintien des branches élastiques de connexion et de logement pour le fil électrique conducteur.This arrangement makes it possible to reduce the size of the plug-in connector by assigning to the base of the connection plug the dual function of holding the elastic connection and housing legs for the conductive electrical wire.

Selon un aspect de l'invention, le passage est réalisé dans le corps isolant.According to one aspect of the invention, the passage is made in the insulating body.

C'est ainsi que par exemple l'absence de portions du corps isolant entre le premier logement de la borne de connexion et le deuxième logement formé dans l'embase de la prise de connexion peut permettre de former un passage pour le fil électrique conducteur. Le deuxième logement est disposé dans l'alignement du premier logement selon la direction d'insertion du fil électrique conducteur.Thus, for example, the absence of portions of the insulating body between the first housing of the connection terminal and the second housing formed in the base of the connection socket may make it possible to form a passage for the conductive electrical wire. The second housing is disposed in alignment with the first housing in the direction of insertion of the conductive electrical wire.

Cette disposition permet de faciliter l'accès du fil électrique conducteur au deuxième logement.This arrangement makes it easier to access the conductive electrical wire to the second housing.

Selon un aspect de l'invention, l'embase de la prise de connexion présente un profil en forme de U.According to one aspect of the invention, the base of the connection socket has a U-shaped profile.

Cette disposition permet de créer aisément l'embase de la prise de connexion en prolongeant les deux branches élastiques de connexion à partir des deux branches de la forme en U. La borne de connexion est du type ressort à lame.This arrangement makes it possible to easily create the base of the connection socket by extending the two elastic connection branches from the two branches of the U-shape. The connection terminal is of the leaf spring type.

Cette disposition permet de faciliter l'insertion du fil électrique conducteur dans la borne de connexion. La borne de connexion du type ressort à lame comprend une partie conductrice, ladite partie conductrice et la prise de connexion étant formées en une seule pièce.This arrangement makes it easier to insert the conductive electrical wire into the connection terminal. The spring-type connection terminal comprises a conductive portion, said conductive portion and the connection socket being formed in one piece.

Cette disposition permet de faciliter l'assemblage du connecteur débrochable tout en optimisant les coûts de fabrication. La partie conductrice comprend une première portion présentant une ouverture disposée en regard de la première ouverture du corps isolant.This arrangement makes it easier to assemble the plug-in connector while optimizing manufacturing costs. The conductive portion comprises a first portion having an opening disposed facing the first opening of the insulating body.

La présence d'une ouverture permet de disposer la première portion transversalement à la direction d'extension du fil électrique conducteur tout en le laissant passer. Ainsi il n'est pas nécessaire de prévoir une première portion contournant le fil électrique conducteur. Cette disposition permet donc de réaliser une partie conductrice compacte et ainsi de réaliser un gain de place et de matière.The presence of an opening makes it possible to arrange the first portion transversely to the extension direction of the conductive electric wire while allowing it to pass. Thus it is not necessary to provide a first portion bypassing the conductive electrical wire. This arrangement therefore makes it possible to produce a compact conductive part and thus to save space and material.

Selon un aspect de l'invention, la partie conductrice comprend une deuxième portion et un coude reliant la première portion à la deuxième portion.According to one aspect of the invention, the conductive portion comprises a second portion and an elbow connecting the first portion to the second portion.

Selon un aspect de l'invention, la deuxième portion est pleine et s'étend dans un plan sensiblement parallèle à la direction d'insertion du fil électrique conducteur.According to one aspect of the invention, the second portion is solid and extends in a plane substantially parallel to the direction of insertion of the conductive electrical wire.

Selon un aspect de l'invention, la première portion s'étend sensiblement dans un plan incliné par rapport à un plan transversal à la direction d'insertion du fil conducteur électrique.According to one aspect of the invention, the first portion extends substantially in a plane inclined relative to a plane transverse to the direction of insertion of the electrical conductor wire.

Selon un aspect de l'invention, la borne de connexion du type ressort à lame comprend un ressort à lame comportant une branche d'appui et une branche de serrage reliées par une coude.According to one aspect of the invention, the connection terminal of the leaf spring type comprises a leaf spring having a bearing leg and a clamping leg connected by a bend.

Cette disposition permet un gain de place supplémentaire dans le corps isolant du connecteur débrochable.This arrangement allows additional space saving in the insulating body of the plug-in connector.

Selon un aspect de l'invention, la branche d'appui prend appui sur un premier bord de l'ouverture de la première portion et dans lequel la branche de serrage est destinée à serrer le fil électrique conducteur contre un deuxième bord de l'ouverture de la première portion opposé au premier bord et contre la deuxième portion de la borne de connexion.According to one aspect of the invention, the support branch bears on a first edge of the opening of the first portion and wherein the clamping branch is intended to clamp the conductive electric wire against a second edge of the opening the first portion opposite the first edge and against the second portion of the connection terminal.

L'ouverture est destinée non seulement au passage du fil électrique conducteur mais est également destinée à servir de support au ressort à lames. Cette disposition permet donc un gain de place et de matière en réalisant un agencement compact de la borne de connexion. Le corps isolant comprend une portion disposée entre les deux branches élastiques de connexion et de manière adjacente au deuxième logement.The opening is intended not only for the passage of the conductive electrical wire but is also intended to serve as a support for the leaf spring. This arrangement therefore saves space and material by providing a compact arrangement of the connection terminal. The insulating body comprises a portion disposed between the two elastic connection legs and adjacent to the second housing.

Cette disposition permet de créer une butée de manière à empêcher le fil électrique conducteur d'interférer lors de l'insertion de la prise de connexion du connecteur débrochable dans la prise de connexion complémentaire du bloc de jonction.This arrangement makes it possible to create a stop so as to prevent the conductive electrical wire from interfering during the insertion of the connection socket of the withdrawable connector into the complementary connection socket of the terminal block.

Selon un aspect de l'invention, le connecteur débrochable présente un encombrement hors tout de moins de 35 mm.According to one aspect of the invention, the plug-in connector has an overall size of less than 35 mm.

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 connecteur débrochable selon l'invention.In any case, the invention will be better understood from the description which follows, with reference to the appended schematic drawing showing, by way of non-limiting example, a plug-in connector according to the invention.

La première portion 12 présente une ouverture 13 disposée en regard de la première ouverture 3 du corps isolant 2.The first portion 12 has an opening 13 disposed opposite the first opening 3 of the insulating body 2.

En outre, la première portion 12 s'étend sensiblement dans un plan incliné par rapport à un plan transversal à la direction D d'insertion du fil électrique conducteur C.In addition, the first portion 12 extends substantially in a plane inclined relative to a plane transverse to the insertion direction D of the conductive electrical wire C.

La deuxième portion 14 est pleine et s'étend sensiblement dans un plan sensiblement parallèle à la direction D d'insertion du fil électrique conducteur C.The second portion 14 is solid and extends substantially in a plane substantially parallel to the insertion direction D of the conductive electrical wire C.

La première portion 12 et la deuxième portion 14 sont réalisées dans un matériau conducteur d'électricité.The first portion 12 and the second portion 14 are made of an electrically conductive material.

En outre, le ressort à lame 16 de la borne de connexion 10 comprend une première branche d'appui 17 prenant appui sur un premier bord de l'ouverture 13 de la première portion 12 et une branche de serrage 18 mobile destinée à serrer le fil électrique conducteur C contre un deuxième bord de l'ouverture 13 de la première portion 12 opposé au premier bord et contre la deuxième portion 14 de la borne de connexion 10.In addition, the leaf spring 16 of the connection terminal 10 comprises a first support branch 17 bearing on a first edge of the opening 13 of the first portion 12 and a movable clamping leg 18 for tightening the wire electrical conductor C against a second edge of the opening 13 of the first portion 12 opposite the first edge and against the second portion 14 of the connection terminal 10.

La branche d'appui 17 et la branche de serrage 18 sont reliées par un coude 19.The support branch 17 and the clamping branch 18 are connected by a bend 19.

Le retrait du fil électrique conducteur C du corps isolant 2 peut être réalisé en appliquant une contrainte sur la branche de serrage 18 du ressort à lame 16 à l'aide d'un outil inséré au travers la troisième ouverture 5.The removal of the conductive electrical wire C from the insulating body 2 can be achieved by applying a stress on the clamping branch 18 of the leaf spring 16 by means of a tool inserted through the third opening 5.

La borne de connexion 10 forme ainsi un logement 8 pour le fil électrique conducteur C introduit dans le corps isolant 2 au travers la première ouverture 3.The connection terminal 10 thus forms a housing 8 for the conductive electrical wire C introduced into the insulating body 2 through the first opening 3.

Dans l'exemple proposé, ce logement 8 peut être défini comme étant une zone de l'espace située sensiblement entre les deux plans dans lesquels s'étendent sensiblement la première portion 12 et la deuxième portion 14 de la partie conductrice 11 de la borne de connexion 10 et un plan sensiblement transversal à la direction d'insertion D du fil électrique conducteur C dans le corps isolant 2 dans lequel s'inscrit l'extrémité libre de la première portion 12 de la partie conductrice 11 de la borne de connexion 10.In the example proposed, this housing 8 can be defined as being an area of the space located substantially between the two planes in which substantially the first portion 12 and the second portion 14 of the conductive portion 11 of the terminal of connection 10 and a plane substantially transverse to the insertion direction D of the conductive electrical wire C in the insulating body 2 in which the free end of the first portion 12 of the conductive portion 11 of the connection terminal 10 is inscribed.

La prise de connexion 20 comprend quant à elle une embase 21 présentant un profil en forme de U présentant une base 21a et deux branches 21b, 21c.The connection socket 20 comprises a base 21 having a U-shaped profile having a base 21a and two branches 21b, 21c.

Les branches 21b, 21c de la forme en U de l'embase 21 s'étendent sensiblement selon une direction transversale à la direction D d'insertion du fil électrique conducteur C dans le corps isolant 2 et selon deux plans sensiblement parallèles au plan dans lequel s'étend la deuxième portion 14 de la partie conductrice 11 de la borne de connexion 10.The branches 21b, 21c of the U-shape of the base 21 extend substantially in a direction transverse to the insertion direction D of the conductive electrical wire C in the insulating body 2 and in two planes substantially parallel to the plane in which extends the second portion 14 of the conductive portion 11 of the connection terminal 10.

En outre, dans l'exemple présenté la deuxième portion 14 de la partie conductrice 11 de la borne de connexion 10 est directement reliée à un bord latéral d'une des branches 21b de l'embase 21 en forme de U en regard de la borne de connexion 10.In addition, in the example shown, the second portion 14 of the conductive portion 11 of the connection terminal 10 is directly connected to a lateral edge of one of the branches 21b of the U-shaped base 21 opposite the terminal connection 10.

De plus, cette branche 21b de l'embase 21 et la deuxième portion 14 de la partie conductrice 11 de la borne de connexion 10 s'étendent dans un même plan.In addition, this branch 21b of the base 21 and the second portion 14 of the conductive portion 11 of the connection terminal 10 extend in the same plane.

Enfin, la prise de connexion 20 comprend deux branches élastiques de connexion 22a, 22b s'étendant chacune à partir d'un des deux bords des branches 21b, 21c de l'embase 21 en forme de U opposés aux deux bords en regard de la borne de connexion 10.Finally, the connection socket 20 comprises two elastic connecting arms 22a, 22b each extending from one of the two edges of the branches 21b, 21c of the U-shaped base 21 opposite the two edges facing the connection terminal 10.

Ces deux branches de connexion élastiques 22a, 22b forment une prise femelle et sont destinées à assurer un contact électrique avec une prise mâle du bloc de jonction (non illustré) destiné à être inséré entre les deux branches de connexion élastiques 22a, 22b au travers la deuxième ouverture 4 du corps isolant 2.These two elastic connection branches 22a, 22b form a socket and are intended to provide electrical contact with a male plug of the terminal block (not shown) intended to be inserted between the two elastic connection branches 22a, 22b through the second opening 4 of the insulating body 2.

Dans l'exemple présenté, et comme cela apparait la figure 2, la prise de connexion 20 comprenant l'embase 21 et les deux branches de connexion élastiques 21a, 21b sont formés en une seule pièce avec la partie conductrice 11 de la borne de connexion 10 comprenant la première portion 12 et la deuxième portion 14.In the example presented, and as it appears figure 2 , the connection socket 20 comprising the base 21 and the two elastic connection branches 21a, 21b are formed in one piece with the conductive portion 11 of the connection terminal 10 comprising the first portion 12 and the second portion 14.

L'embase 21 de la prise de connexion 20 forme un deuxième logement 9 en plus du premier logement 8 pour le fil électrique conducteur C introduit dans le corps isolant 2 au travers la première ouverture 3.The base 21 of the connection socket 20 forms a second housing 9 in addition to the first housing 8 for the conductive electrical wire C introduced into the insulating body 2 through the first opening 3.

Dans l'exemple présenté, ce deuxième logement 9 peut être défini comme étant une zone de l'espace située sensiblement entre les deux branches 21b, 21c de l'embase 21 en forme de U de la prise de connexion 20.In the example presented, this second housing 9 can be defined as being an area of the space situated substantially between the two branches 21b, 21c of the U-shaped base 21 of the connection socket 20.

De même, dans l'exemple présenté le deuxième logement 9 est disposé dans l'alignement du premier logement 8 pour le fil électrique conducteur C de la borne de connexion 10 selon la direction d'insertion D du fil électrique conducteur C.Similarly, in the example shown the second housing 9 is disposed in alignment with the first housing 8 for the conductive wire C of the connection terminal 10 in the direction of insertion D of the electrical conductor wire C.

En outre, le connecteur débrochable 1 comprend un passage 6 entre le premier logement 8 et le deuxième logement 9 afin de permettre à l'extrémité C' du fil électrique conducteur C d'atteindre le deuxième logement 9 après avoir traversé le premier logement 8.In addition, the detachable connector 1 comprises a passage 6 between the first housing 8 and the second housing 9 in order to allow the end C 'of the conductive electrical wire C to reach the second housing 9 after having passed through the first housing 8.

Ce passage 6 résulte de l'absence de portions de la borne de connexion 10 et/ou de la prise de connexion 20 et/ou du corps isolant 2 entre le premier logement 8 et le deuxième logement 9.This passage 6 results from the absence of portions of the connection terminal 10 and / or the connection socket 20 and / or the insulating body 2 between the first housing 8 and the second housing 9.

Enfin, le corps isolant 2 comprend une portion 7 disposée entre les deux branches de connexion élastiques 22a, 22b et de manière adjacente au deuxième logement 9 de manière à empêcher l'extrémité C' du fil électrique conducteur C d'atteindre la prise de connexion 20.Finally, the insulating body 2 comprises a portion 7 disposed between the two elastic connection branches 22a, 22b and adjacent to the second housing 9 so as to prevent the end C 'of the conductive electrical wire C from reaching the connection socket 20.

Le connecteur débrochable 1 présente un encombrement hors tout ou hauteur de moins de 35 mm contre un encombrement d'au moins 40 mm pour un connecteur débrochable de l'état de la technique.The detachable connector 1 has an overall size or height of less than 35 mm against a footprint of at least 40 mm for a plug-in connector of the state of the art.

Ce gain de place, dû à la présence du deuxième logement 9, permet de réduire l'écart entre les rails supports des blocs de jonction et par conséquent permet d'augmenter le nombre de blocs pouvant équiper une armoire ou un coffret électrique.This space saving, due to the presence of the second housing 9, reduces the gap between the support rails of the terminal blocks and therefore increases the number of blocks that can equip a cabinet or an electrical box.

Bien que l'invention ait été décrite en liaison avec des exemples particuliers de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons.Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it includes all the technical equivalents of the means described and their combinations.

C'est ainsi que dans un mode de réalisation non illustré, le deuxième logement 9 n'est pas disposé directement dans l'alignement du premier logement 8 selon la direction d'insertion D du fil électrique conducteur C mais est légèrement décalé par rapport à celui-ci.Thus, in a non-illustrated embodiment, the second housing 9 is not arranged directly in alignment with the first housing 8 in the direction of insertion D of the conductive electrical wire C but is slightly offset with respect to this one.

Dans un tel mode de réalisation, le fil électrique conducteur C traverse le premier logement 8 puis est guidé vers le deuxième logement 9 au travers le passage 6 en glissant le long de la deuxième portion 14 de la partie conductrice 11 de la borne de connexion 10.In such an embodiment, the conductive electrical wire C passes through the first housing 8 and is guided towards the second housing 9 through the passage 6 by sliding along the second portion 14 of the conductive portion 11 of the connection terminal 10 .
