Description

La présente invention concerne un contacteur électrique comprenant un boitier formé dans un matériau électriquement isolant et au moins une borne de connexion de type à pression incluant au moins une ouverture d'insertion délimitée par le boitier permettant d'insérer un conducteur électrique vers l'intérieur du boitier et un ressort de serrage monté dans le boitier pour maintenir le conducteur électrique après son insertion.The present invention relates to an electric contactor comprising a housing formed in an electrically insulating material and at least one pressure-type connection terminal including at least one insertion opening defined by the housing for inserting an electrical conductor inwards housing and a clamping spring mounted in the housing to hold the electrical conductor after insertion.

De manière connue, un contacteur électrique est un appareil électrique comprenant un boitier électriquement isolant renfermant une pluralité de contacts électriques variant chacun, par une commande externe notamment de type électrique, entre une configuration fermée établissant une connexion électrique et une configuration ouverte où la connexion électrique n'est pas établie. Un contacteur électrique comprend aussi une pluralité de bornes de connexion montées dans le boitier et des éléments permettant de fixer de manière démontable le boitier sur un support, par exemple un rail de support d'une armoire électrique.In a known manner, an electrical contactor is an electrical apparatus comprising an electrically insulating housing enclosing a plurality of electrical contacts each varying, by an external control particularly of electrical type, between a closed configuration establishing an electrical connection and an open configuration where the electrical connection is not established. An electric contactor also comprises a plurality of connection terminals mounted in the housing and elements for removably fixing the housing on a support, for example a support rail of an electrical cabinet.

Classiquement, les bornes de connexion d'un contacteur électrique permettent de raccorder électriquement au moins un conducteur électrique tel qu'un fil électrique. Le conducteur électrique ainsi raccordé par l'intermédiaire de l'une des bornes de connexion est destiné à être relié électriquement à un élément conducteur interne au contacteur, cet élément conducteur étant lui-même relié électriquement à une partie fixe de l'un des contacts électriques.Conventionally, the connection terminals of an electrical contactor make it possible to electrically connect at least one electrical conductor such as an electric wire. The electrical conductor thus connected via one of the connection terminals is intended to be electrically connected to a conductive element internal to the contactor, this conductive element being itself electrically connected to a fixed part of one of the contacts. electric.

Dans le domaine des contacteurs électriques, il existe classiquement trois types de borne de connexion :

  • les bornes de connexion assurant la retenue du conducteur électrique après une opération de vissage d'un organe de serrage,
  • les bornes de connexion comprenant un ressort qu'il convient d'ouvrir à l'aide d'un outil adapté pour la mise en place du conducteur électrique et qui se referme automatiquement après le retrait de cet outil,
  • les bornes de connexion de type à pression fonctionnant par enfichage direct, également connues dans le domaine concerné sous le terme « push-in » en terminologie anglo-saxonne.
In the field of electrical contactors, there are conventionally three types of connection terminal:
  • the connection terminals ensuring the retention of the electrical conductor after a screwing operation of a clamping member,
  • the connection terminals comprising a spring which should be opened with the aid of a tool adapted for setting up the electrical conductor and which closes automatically after the removal of this tool,
  • the pressure-type connection terminals operating by direct plugging, also known in the field concerned by the term "push-in" in English terminology.

Les deux premières catégories ci-dessous, bien que totalement efficaces, ne sont pas totalement satisfaisantes d'un point de vue pratique car il est nécessaire de manipuler un outil à la mise en place de chaque conducteur électrique. En outre, elles laissent subsister une possibilité que le conducteur électrique mis en place ne soit pas correctement raccordé en fonction de la manière dont l'opérateur manipule l'outil.The first two categories below, although totally effective, are not totally satisfactory from a practical point of view because it is necessary to manipulate a tool to the introduction of each electrical conductor. In addition, they leave a possibility that the installed electrical conductor is not properly connected depending on how the operator handles the tool.

C'est pourquoi, les bornes de connexion de type push-in sont intéressantes, car elles permettent notamment de s'affranchir de ces inconvénients.This is why the push-in connection terminals are interesting because they make it possible to overcome these disadvantages.

Dans le cas particulier des bornes de connexion de type à pression, chaque borne de connexion comprend un ressort de serrage agencé de sorte à s'ouvrir automatiquement sous l'action de l'insertion du conducteur électrique dans le ressort de serrage et à exercer ensuite, par rappel élastique de sa matière, un effort de pression sur le conducteur électrique après son insertion, cet effort de pression étant capable de maintenir le conducteur électrique dans un état bloqué axialement par le ressort de serrage.In the particular case of the pressure type connection terminals, each connection terminal comprises a clamping spring arranged so as to open automatically under the action of the insertion of the electrical conductor into the clamping spring and then to exert , by elastic return of its material, a pressure force on the electrical conductor after its insertion, this pressure force being able to maintain the electrical conductor in an axially locked state by the clamping spring.

Le retrait d'un conducteur électrique s'effectue généralement par l'intermédiaire d'un outil allongé de type tournevis inséré dans une lumière ménagée dans le boitier jusqu'à permettre d'écarter le ressort afin de libérer le conducteur électrique de l'effort de pression et permettre son retrait hors de la borne de connexion.The withdrawal of an electrical conductor is generally effected by means of an elongated tool such as a screwdriver inserted into a slot in the housing until the spring can be moved aside to release the electrical conductor from the effort pressure and allow it to be removed from the connection terminal.

Ces solutions ne donnent pas une entière satisfaction car cela s'avère peu pratique de devoir obligatoirement manipuler un outil, et ce à chaque conducteur électrique à retirer. En outre ces solutions restent difficiles à implémenter dans des situations où il est recherché un caractère compact du contacteur électrique.These solutions do not give complete satisfaction because it is impractical to have to handle a tool, and each electrical conductor to remove. In addition, these solutions remain difficult to implement in situations where the compact nature of the electric switch is sought.

Le but de la présente invention est de répondre à tout ou partie des inconvénients présentés ci-avant.The object of the present invention is to meet all or some of the disadvantages presented above.

Ce but peut être atteint grâce à la fourniture d'un contacteur électrique comprenant un boitier formé dans un matériau électriquement isolant et au moins une borne de connexion de type à pression incluant d'une part au moins une ouverture d'insertion délimitée par le boitier permettant d'insérer un conducteur électrique vers l'intérieur du boitier, d'autre part un ressort de serrage monté dans le boitier et apte à occuper une configuration active où une branche de serrage du ressort de serrage peut librement se déplacer sous l'effet de l'insertion à force du conducteur électrique entre le boitier et la branche de serrage au niveau de l'ouverture d'insertion, depuis une position naturelle de fermeture, vers une position d'ouverture partielle de la branche de serrage dans laquelle elle assure un contact mécanique et électrique entre le conducteur électrique inséré et une barrette conductrice montée dans le boitier et une retenue du conducteur électrique, dans lequel le contacteur électrique comprend au moins un bouton poussoir destiné à l'actionnement du ressort de serrage.This object can be achieved by providing an electric contactor comprising a housing formed of an electrically insulating material and at least one pressure type connection terminal including on the one hand at least one insertion opening defined by the housing. to insert an electrical conductor towards the inside of the housing, on the other hand a clamping spring mounted in the housing and able to occupy an active configuration where a tightening leg of the clamping spring can freely move under the effect of the force insertion of the electrical conductor between the housing and the clamping branch at the level of the insertion opening, from a natural closing position, to a partial opening position of the clamping branch in which it provides a mechanical and electrical contact between the inserted electrical conductor and a conducting bar mounted in the housing and a electrical conductor restraint, wherein the electrical contactor comprises at least one pushbutton for actuating the clamping spring.

Le bouton poussoir peut notamment être monté dans le boitier de sorte à être déplacé, sous l'effet d'une force extérieure d'appui, d'une position relevée dans laquelle le bouton poussoir autorise le ressort de serrage à occuper sa configuration active vers une position abaissée vers l'intérieur du boitier dans laquelle une surface d'appui du bouton poussoir presse sur le ressort de serrage d'une manière plaçant le ressort de serrage dans une configuration inactive où sa branche de serrage occupe une position d'ouverture totale dans laquelle le conducteur électrique peut librement être retiré hors de la borne de connexion vers l'extérieur du boitier.The push button may in particular be mounted in the box so as to be displaced, under the effect of an external bearing force, of a raised position in which the push button authorizes the clamping spring to occupy its active configuration towards a lowered position towards the inside of the housing in which a bearing surface of the push button presses on the clamping spring in a manner placing the clamping spring in an inactive configuration where its clamping branch occupies a fully open position wherein the electrical conductor can freely be removed from the connection terminal to the outside of the housing.

Un tel contacteur électrique présente l'avantage d'être compact et permettre de retirer de manière fiable, aisée et pratique, un conducteur électrique hors de la borne de connexion qui le retient. Il suffit d'exercer une poussée sur le bouton poussoir jusqu'à placer le ressort de serrage dans la configuration inactive. Il est même possible de configurer le contacteur électrique de sorte que l'actionnement d'un seul bouton poussoir puisse commander l'ouverture de plusieurs ressorts en même temps, ce qui simplifie encore plus la gestion des conducteurs électriques et renforce encore plus l'ergonomie pour l'utilisateur. En fonction de l'organisation de chaque bouton poussoir, il peut avantageusement être possible d'exercer cette poussée directement par le doigt de l'utilisateur, s'affranchissant alors de toute nécessité à recourir à un outil tel qu'un tournevis.Such an electric contactor has the advantage of being compact and allow to reliably, easily and conveniently remove an electrical conductor from the connection terminal which holds it. Simply push the push button until the clamp spring is in the inactive configuration. It is even possible to configure the electric contactor so that the actuation of a single push button can control the opening of several springs at the same time, which further simplifies the management of electrical conductors and further enhances the ergonomics for the user. Depending on the organization of each push button, it may advantageously be possible to exert this thrust directly by the finger of the user, then free from any need to use a tool such as a screwdriver.

Le contacteur électrique peut également répondre aux caractéristiques techniques présentées ci-après, prises isolément ou en combinaison.The electric contactor can also meet the technical characteristics presented below, taken separately or in combination.

Dans la position relevée, le bouton poussoir fait saillie par rapport au boitier.In the raised position, the push button protrudes from the housing.

Cette disposition présente l'avantage que le bouton poussoir peut être actionné soit manuellement, soit par l'intermédiaire d'un outil de type tournevis.This arrangement has the advantage that the push button can be operated either manually or by means of a screwdriver type tool.

Dans la position relevée, le bouton poussoir est affleurant par rapport au boitier.In the raised position, the push button is flush with the housing.

Cette disposition présente l'avantage que le bouton poussoir ne peut être actionné que par l'intermédiaire d'un outil de type tournevis, évitant les appuis manuels involontaires sur le bouton poussoir.This arrangement has the advantage that the push button can be operated only by means of a screwdriver-type tool, avoiding inadvertent manual pressing on the push button.

Une empreinte creuse est ménagée dans une face supérieure du bouton poussoir accessible depuis l'extérieur, ladite empreinte creuse étant adaptée à l'introduction d'une pointe de tournevis.A hollow cavity is formed in an upper face of the push button accessible from the outside, said hollow cavity being adapted to the introduction of a screwdriver tip.

Le contacteur électrique comprend au moins deux ressorts de serrage distincts et le bouton poussoir est configuré de sorte à pouvoir coopérer avec un seul ressort de serrage parmi lesdits au moins deux ressorts de serrage.The electrical contactor comprises at least two separate clamping springs and the pushbutton is configured so as to cooperate with a single clamping spring among said at least two clamping springs.

Le contacteur électrique comprend au moins deux ressorts de serrage distincts et le bouton poussoir est configuré de sorte à pouvoir coopérer avec lesdits au moins deux ressorts de serrage, de manière à les placer simultanément dans leurs configurations inactives lorsque le bouton poussoir occupe sa position abaissée et à les placer simultanément dans leurs configurations actives lorsque le bouton poussoir occupe sa position relevée.The electrical contactor comprises at least two separate clamping springs and the pushbutton is configured so as to cooperate with said at least two clamping springs, so as to place them simultaneously in their inactive configurations when the pushbutton is in its lowered position and to place them simultaneously in their active configurations when the push button is in its raised position.

Le boitier et le bouton poussoir délimitent respectivement des premiers éléments et des seconds éléments d'un même mécanisme de blocage, complémentaires et aptes à coopérer entre eux de sorte que le mécanisme de blocage assure un blocage positif du bouton poussoir dans sa position abaissée.The housing and the push button delimit respectively first elements and second elements of the same locking mechanism, complementary and capable of cooperating with each other so that the locking mechanism ensures a positive blocking of the push button in its lowered position.

Le mécanisme de blocage est configuré de sorte que le déblocage du bouton poussoir, pour autoriser son déplacement vers la position relevée, résulte d'un mouvement de basculement du bouton poussoir selon un axe perpendiculaire à la trajectoire de déplacement du bouton poussoir durant le passage de la position relevée vers la position abaissée, ledit mouvement de basculement étant obtenu sous l'effet d'une force extérieure de basculement appliquée au bouton poussoir.The locking mechanism is configured so that the release of the push button, to allow its movement to the raised position, results from a tilting movement of the push button along an axis perpendicular to the path of movement of the push button during the passage of the position raised towards the lowered position, said tilting movement being obtained under the effect of an external tilting force applied to the push button.

Le déplacement du bouton poussoir de la position abaissée vers la position relevée est réalisé par l'action du ressort de serrage durant son retour vers sa configuration active.The movement of the pushbutton from the lowered position to the raised position is achieved by the action of the clamping spring during its return to its active configuration.

Le boitier et le bouton poussoir délimitent respectivement des premiers éléments et des seconds éléments d'un même système de retenue, complémentaires et aptes à coopérer par encliquetage entre eux de sorte que le système de retenue assure une retenue du bouton poussoir dans sa position relevée pour éviter une sortie du bouton poussoir vers l'extérieur du boitier.The housing and the push button delimit respectively first elements and second elements of the same retaining system, complementary and able to cooperate by snapping between them so that the retaining system ensures a retention of the push button in its raised position to avoid an exit of the push button towards the outside of the box.

Le boitier et le bouton poussoir délimitent respectivement des premiers éléments et des seconds éléments d'un même système de guidage en translation, complémentaires et aptes à coopérer entre eux de sorte que le passage de la position relevée vers la position abaissée, et réciproquement, se pratique par un coulissement du bouton poussoir par rapport au boitier.The box and the push button delimit respectively first elements and second elements of the same translational guide system, complementary and capable of cooperating with each other so that the passage from the raised position to the lowered position, and vice versa, practice by sliding the push button relative to the housing.

Enfin, les Figures 10 et 11 illustrent, en coupe longitudinale partielle, le contacteur électrique de la Figure 1 respectivement dans la position relevée et dans la position abaissée de l'un des boutons poussoirs.Finally, Figures 10 and 11 illustrate, in partial longitudinal section, the electrical contactor of the Figure 1 respectively in the raised position and in the lowered position of one of the push buttons.

En référence aux Figures 1 à 11 annexées telles que présentées sommairement ci-dessus, l'invention concerne essentiellement un contacteur électrique 10 comprenant un boitier 11 formé dans un matériau électriquement isolant.With reference to Figures 1 to 11 appended hereto as summarily presented above, the invention essentially relates to an electric contactor 10 comprising a housing 11 formed of an electrically insulating material.

Sur les Figures, on voit que le boitier 11 comprend des éléments de fixation 12 aménagés sur sa face arrière, permettant de fixer, par exemple par encliquetage, le boitier 11 sur un rail de fixation d'une armoire électrique.In the figures, we see that the housing 11 comprises fastening elements 12 arranged on its rear face, for fixing, for example by snapping, the housing 11 on a mounting rail of an electrical cabinet.

Le boitier 11 se compose d'une embase 11a qui porte, sur une face arrière, les éléments de fixation 12 et d'un couvercle 11b venant se monter de manière démontable sur une face avant de l'embase 11a.The housing 11 consists of a base 11a which carries, on a rear face, the fastening elements 12 and a cover 11b to be removably mounted on a front face of the base 11a.

En référence à la Figure 7, le contacteur électrique 10 comprend une pluralité de contacts électriques ayant chacun une partie mobile 13a et une partie fixe 13b et variant chacun, par une commande externe notamment de type électrique, entre une configuration fermée établissant un contact électrique entre la partie mobile 13a et la partie fixe 13b et une configuration ouverte où ce contact électrique entre les parties 13a, 13b n'est pas établi. A titre d'exemple, la partie mobile 13a des contacts électriques est solidaire d'une armature mobile 13c apte à se déplacer dans un sens sous l'effet d'un champ magnétique imposé par exemple par une bobine et dans le sens inverse sous l'effet d'un mécanisme de rappel 13d. Tous ces éléments sont montés dans l'embase 11a.With reference to the Figure 7 , the electrical contactor 10 comprises a plurality of electrical contacts each having a movable portion 13a and a fixed portion 13b and each varying, by an external control particularly of electrical type, between a closed configuration establishing an electrical contact between the movable portion 13a and the fixed part 13b and an open configuration where this electrical contact between parts 13a, 13b is not established. For example, the movable portion 13a of the electrical contacts is secured to a movable armature 13c able to move in one direction under the effect of a magnetic field imposed for example by a coil and in the opposite direction under effect of a return mechanism 13d. All these elements are mounted in the base 11a.

Le contacteur électrique 10 comprend également une pluralité de bornes de connexion, chacune étant de type « à pression » de sorte à fonctionner par enfichage direct, également connues dans le domaine concerné sous le terme « push-in » en terminologie anglo-saxonne. Chaque borne de connexion inclut d'une part au moins une ouverture d'insertion 14 délimitée par le couvercle 11b du boitier 11 permettant d'insérer un conducteur électrique (par exemple un fil électrique) vers l'intérieur du boitier 11, d'autre part un ressort de serrage 15 monté dans l'embase 11a du boitier 11.The electrical contactor 10 also comprises a plurality of connection terminals, each of which is of the "pressure" type so as to operate by direct plugging, also known in the field concerned by the term "push-in" in English terminology. Each connection terminal includes on the one hand at least one insertion opening 14 delimited by the cover 11b of the housing 11 for inserting an electrical conductor (for example an electrical wire) towards the inside of the housing 11, on the other hand part of a clamping spring 15 mounted in the base 11a of the housing 11.

De manière générale, le ressort de serrage 15 est agencé de sorte à s'ouvrir automatiquement sous l'action de l'insertion du conducteur électrique dans le ressort de serrage 15 et à exercer ensuite, par rappel élastique de sa matière, un effort de pression sur le conducteur électrique après son enfichage, cet effort de pression étant capable de maintenir le conducteur électrique dans un état bloqué axialement par le ressort de serrage 15. Notamment, les ressorts de serrage 15 sont montés dans l'embase 11a du boitier 11.In general, the clamping spring 15 is arranged so as to open automatically under the action of the insertion of the electrical conductor in the clamping spring 15 and to then exert, by elastic return of its material, an effort of pressure on the electrical conductor after its insertion, this pressure force being able to maintain the electrical conductor in an axially locked state by the clamping spring 15. In particular, the clamping springs 15 are mounted in the base 11a of the housing 11.

Plus précisément, le ressort de serrage 15 est apte à occuper une configuration active (Figure 10) où une branche de serrage 15a du ressort de serrage 15 peut librement se déplacer sous l'effet de l'insertion à force du conducteur électrique entre le boitier 11 et la branche de serrage 15a au niveau de l'ouverture d'insertion 14, depuis une position naturelle de fermeture (visible sur la Figure 10), vers une position d'ouverture partielle (non représentée) de la branche de serrage 15a dans laquelle elle assure un contact mécanique et électrique entre le conducteur électrique inséré et une barrette conductrice 16 montée dans l'embase 11a du boitier 11 et une retenue du conducteur électrique. Typiquement, la partie fixe 13b des contacts électriques est solidaire de la barrette conductrice 16.More specifically, the clamping spring 15 is able to occupy an active configuration ( Figure 10 ) where a clamping limb 15a of the clamping spring 15 can freely move under the effect of the insertion of the electrical conductor between the housing 11 and the clamping branch 15a at the insertion opening 14, from a natural closing position (visible on the Figure 10 ), towards a partial opening position (not shown) of the clamping branch 15a in which it provides a mechanical and electrical contact between the inserted electrical conductor and a conductive strip 16 mounted in the base 11a of the housing 11 and a restraint of the electrical conductor. Typically, the fixed portion 13b of the electrical contacts is integral with the conductive strip 16.

Par exemple, chaque ressort de contact 15 adopte la forme générale d'une lame élastique qui délimite, outre la branche de serrage 15a, une branche de maintien 15b qui vient en appui constant contre le boitier 11 afin de maintenir le ressort de serrage 15 en position dans le boitier 11 durant les changements de position de la branche de serrage 15a. La branche de serrage 15a est raccordée à la branche de maintien 15b par un coude de raccordement élastique 15c.For example, each contact spring 15 adopts the general shape of a resilient blade which delimits, in addition to the clamping branch 15a, a holding branch 15b which bears against the housing 11 in a constant manner so as to hold the clamping spring 15 in position. position in the housing 11 during changes in position of the clamping branch 15a. The clamping branch 15a is connected to the holding arm 15b by an elastic connection bend 15c.

De manière avantageuse, comme expliqué précédemment, le contacteur électrique 10 comprend au moins un bouton poussoir 17 destiné à l'actionnement du ressort de serrage 15.Advantageously, as explained above, the electric contactor 10 comprises at least one push button 17 for actuating the clamping spring 15.

Notamment, chacun des boutons poussoirs 17 est monté dans le boitier 11 de sorte à être déplacé, sous l'effet d'une force extérieure d'appui, d'une position relevée dans laquelle le bouton poussoir 17 autorise le ressort de serrage 15 à occuper sa configuration active vers une position abaissée vers l'intérieur du boitier 11 dans laquelle une surface d'appui 17a du bouton poussoir 17 presse sur le ressort de serrage 15 d'une manière plaçant le ressort de serrage 15 dans une configuration inactive (visible sur les Figures 7 et 11) où sa branche de serrage 15a occupe une position d'ouverture totale dans laquelle le conducteur électrique peut librement être retiré hors de la borne de connexion vers l'extérieur du boitier 11. Notamment, les boutons poussoirs 17 sont montés dans le couvercle 11b du boitier 11 à un emplacement leur permettant de coopérer de la manière expliquée dans ce document avec les ressorts de serrage 15 montés, quant à eux, dans l'embase 11a du boitier 11.In particular, each of the push buttons 17 is mounted in the housing 11 so as to be displaced, under the effect of an external bearing force, of a raised position in which the push button 17 allows the clamping spring 15 to occupy its active configuration to a lowered position towards the inside of the housing 11 in which a bearing surface 17a of the push button 17 presses on the clamping spring 15 in a manner that places the clamping spring 15 in an inactive configuration (visible on the Figures 7 and 11 ) where its clamping branch 15a occupies a fully open position in which the electrical conductor can freely be removed from the connection terminal to the outside of the housing 11. In particular, the push buttons 17 are mounted in the cover 11b of the housing 11 at a location allowing them to cooperate in the manner explained in this document with the clamping springs 15 mounted, in turn, in the base 11a of the housing 11.

A titre d'exemple, le bouton poussoir 17 de droite sur la Figure 7 et celui de la Figure 10 occupent chacun sa position relevée, ce qui a pour effet d'autoriser le ressort de serrage 15 avec lequel il coopère d'occuper sa configuration active.For example, the push button 17 on the right on the Figure 7 and that of the Figure 10 each occupy its raised position, which has the effect of allowing the clamping spring 15 with which it cooperates to occupy its active configuration.

A l'inverse, le bouton poussoir 17 de gauche sur la Figure 7 et celui de la Figure 11 occupent chacun sa position abaissée, ce qui a pour conséquence de placer le ressort de serrage 15 avec lequel il coopère dans sa configuration inactive.Conversely, the push button 17 on the left on the Figure 7 and that of the Figure 11 each occupies its lowered position, which has the effect of placing the clamping spring 15 with which it cooperates in its inactive configuration.

Le boitier 11 et le bouton poussoir 17 délimitent respectivement des premiers éléments 20a et des seconds éléments 20b d'un même système de guidage en translation, complémentaires et aptes à coopérer entre eux de sorte que le passage de la position relevée vers la position abaissée, et réciproquement, se pratique par un coulissement du bouton poussoir 17 par rapport au boitier 11. Par exemple, les seconds éléments 20b se présentent sous la forme d'une nervure en saillie par rapport au reste du corps du bouton poussoir 17. Les premiers éléments 20a peuvent se présenter sous la forme d'une lumière ménagée dans l'épaisseur du couvercle 11b dans laquelle vient s'insérer le bouton poussoir 17 à coulissement et munie, sur l'une de ses faces, d'une rainure dans laquelle pénètre et coulisse la nervure solidaire du bouton poussoir 17.The housing 11 and the push button 17 delimit respectively first elements 20a and second elements 20b of the same translational guide system, complementary and capable of cooperating with each other so that the passage from the raised position to the lowered position, and reciprocally, is practiced by a sliding of the pushbutton 17 relative to the housing 11. For example, the second elements 20b are in the form of a rib projecting from the rest of the body of the pushbutton 17. The first elements 20a may be in the form of a lumen formed in the thickness of the cover 11b in which is inserted the push button 17 to slide and provided on one of its faces, a groove into which penetrates and slides the rib integral with the push button 17.

La surface d'appui 17a est globalement inclinée à la manière d'un pan incliné par rapport à la direction de coulissement du bouton poussoir 17, d'une manière permettant de provoquer un écartement progressif de la branche de serrage 15a durant le coulissement du bouton poussoir 17 vers sa position abaissée.The bearing surface 17a is generally inclined in the manner of an inclined face with respect to the direction of sliding of the push button 17, in a manner to cause a progressive separation of the clamping branch 15a during the sliding of the button push 17 to its lowered position.

En référence à toutes les Figures à l'exception de la Figure 8, il est notamment possible de configurer le contacteur électrique 10, par une adaptation correspondante de la hauteur H1 du bouton poussoir 17 de sorte que dans la position relevée, le bouton poussoir 17 fasse saillie par rapport au boitier 11, c'est-à-dire qu'il dépasse par rapport au couvercle 11b. Par conséquent, le passage du ressort de serrage 15 vers la configuration inactive peut se faire soit par un appui sur le bouton poussoir 17 par un outil extérieur 18 (comme par exemple un tournevis comme c'est le cas sur la Figure 9), soit par un appui manuel, jusqu'à la position abaisée.With reference to all Figures except the Figure 8 , it is in particular possible to configure the electric switch 10, by a corresponding adaptation of the height H1 of the push button 17 so that in the raised position, the push button 17 protrudes relative to the housing 11, that is to say say that it exceeds relative to the lid 11b. Therefore, the passage of the clamping spring 15 to the inactive configuration can be done either by pressing the push button 17 by an external tool 18 (such as a screwdriver as is the case on the Figure 9 ), or by manual support, to the lowered position.

Par contre en référence à la Figure 8, il peut être envisagé de configurer le contacteur électrique 10, toujours en adaptant la hauteur du bouton poussoir 17 en conséquence, d'une manière telle que dans la position relevée, le bouton poussoir 17 soit affleurant par rapport au boitier 11. C'est la raison pour laquelle, sur la Figure 8, le bouton poussoir 17 présente une hauteur H2 inférieure à celle H1 des boutons poussoirs 17 présentés sur les autres Figures. Le passage du ressort de serrage 15 vers la configuration inactive peut alors se faire uniquement par un appui sur le bouton poussoir 17 par l'outil extérieur 18 jusqu'à la position abaissée, la zone d'appui sur le bouton poussoir 17 accessible à la main étant trop petite, lorsqu'il est affleurant, pour permettre un appui direct par le doigt.On the other hand, with reference to Figure 8 , it may be envisaged to configure the electric switch 10, always by adjusting the height of the push button 17 accordingly, so that in the raised position, the push button 17 is flush with respect to the housing 11. It is the reason why, on the Figure 8 , the push button 17 has a height H2 less than that H1 push buttons 17 shown in the other Figures. The passage of the clamping spring 15 to the inactive configuration can then be done only by pressing the push button 17 by the outer tool 18 to the lowered position, the support zone on the push button 17 accessible to the hand is too small, when flush, to allow direct support by the finger.

Pour faciliter la manipulation du bouton poussoir 17, une empreinte creuse 19 est ménagée dans une face supérieure du bouton poussoir 17 accessible depuis l'extérieur, cette empreinte creuse 19 étant adaptée à l'introduction d'une pointe de tournevis. Toutefois, comme le montre la Figure 6, une telle empreinte creuse 19 reste facultative.To facilitate the manipulation of the push button 17, a hollow cavity 19 is formed in an upper face of the push button 17 accessible from the outside, this hollow cavity 19 being adapted to the introduction of a screwdriver tip. However, as shown in Figure 6 such a hollow imprint 19 remains optional.

Le contacteur électrique 10 peut notamment comprendre au moins deux ressorts de serrage 15 distincts. Une première possibilité consiste à associer un unique bouton poussoir 17 à un unique ressort de serrage 15, permettant un actionnement sélectif des différents ressorts de serrage 15. Dans ce cas, chaque bouton poussoir 17 est configuré de sorte à pouvoir coopérer avec un seul ressort de serrage 15. En référence à la Figure 5 par contre, une deuxième possibilité alternative qui permet de diminuer le nombre de pièces consiste à prévoir que le bouton poussoir 17 soit configuré de sorte à pouvoir coopérer avec lesdits au moins deux ressorts de serrage 15, de manière à les placer simultanément dans leurs configurations inactives lorsque le bouton poussoir 17 occupe sa position abaissée et à les autoriser simultanément à occuper leurs configurations actives lorsque le bouton poussoir 17 occupe sa position relevée.The electrical contactor 10 may in particular comprise at least two separate clamping springs 15. A first possibility consists of associating a single push button 17 with a single clamping spring 15, allowing selective actuation of the different clamping springs 15. In this case, each push button 17 is configured so as to cooperate with a single spring of 15. With reference to Figure 5 on the other hand, a second alternative possibility that makes it possible to reduce the number of parts consists in providing that the push button 17 is configured so as to be able to cooperate with the said at least two clamping springs 15, so as to place them simultaneously in their inactive configurations when the push button 17 is in its lowered position and simultaneously allow them to occupy their active configurations when the push button 17 is in its raised position.

Avantageusement, le boitier 11 et le bouton poussoir 17 délimitent respectivement des premiers éléments 21a et des seconds éléments 21b d'un même mécanisme de blocage, complémentaires et aptes à coopérer entre eux de sorte que le mécanisme de blocage assure un blocage positif du bouton poussoir 17 dans sa position abaissée. Par « blocage positif », on entend que le blocage est garanti tant qu'aucune action n'est spécifiquement appliquée par l'utilisateur pour assurer le déblocage. Cette fonction peut être aisément obtenue par des principes d'arc-boutement, des principes d'encliquetage, ou des principes de fonctionnement à la manière d'un stylo à bille rétractable. A titre d'exemple, les premiers éléments 21a du mécanisme de blocage se présentent sous la forme d'un cran de retenue ayant une face d'appui inclinée, solidaire du couvercle 11b, et apte à être outrepassé par un ergot d'encliquetage formant les seconds éléments 21b du mécanisme de blocage, cet ergot d'encliquetage ayant également une face d'appui inclinée. La Figure 10 montre la situation où l'ergot d'encliquetage est situé au-dessus, vu dans la direction de coulissement du bouton poussoir 17, du cran de retenue. A l'inverse, la figure 11 montre la situation où l'ergot d'encliquetage est situé en-dessous du cran de retenue, après que leurs faces d'appui inclinées respectives aient coulissé l'une sur l'autre pour provoquer un basculement d'ensemble du bouton poussoir 17 autorisant que l'ergot d'encliquetage outrepasse le cran de retenue jusque dans la situation de blocage positif.Advantageously, the housing 11 and the push button 17 delimit respectively first elements 21a and second elements 21b of the same locking mechanism, complementary and able to cooperate with each other so that the locking mechanism ensures a positive blocking of the push button 17 in its lowered position. By "positive blocking" is meant that the blocking is guaranteed as long as no action is specifically applied by the user to ensure the unlocking. This function can be easily achieved by bracing principles, latching principles, or operating principles in the manner of a retractable ballpoint pen. For example, the first elements 21a of the locking mechanism are in the form of a retaining notch having an inclined bearing face, integral with the cover 11b, and adapted to be overridden by a detent pin forming the second elements 21b of the locking mechanism, this detent pin also having an inclined bearing face. The Figure 10 shows the situation where the detent pin is located above, seen in the sliding direction of the push button 17, the retaining catch. Conversely, the figure 11 shows the situation where the snap lug is located below the retaining catch, after their respective inclined bearing faces have slid one over the other to cause an overall tilting of the push button 17 allowing that the detent pin extends beyond the retaining catch into the positive locking situation.

Le mécanisme de blocage peut être configuré de sorte que le déblocage du bouton poussoir 17, pour autoriser son déplacement vers la position relevée, résulte d'un mouvement de basculement du bouton poussoir 17 selon un axe perpendiculaire à la trajectoire de déplacement du bouton poussoir 17 durant le passage de la position relevée vers la position abaissée, ce mouvement de basculement du bouton poussoir 17 étant obtenu sous l'effet d'une force extérieure de basculement appliquée au bouton poussoir 17 par l'utilisateur. Depuis la situation de la Figure 11, le basculement a pour effet de libérer l'ergot d'encliquetage par rapport au cran de retenue, afin d'autoriser le bouton poussoir à revenir à la situation de la Figure 10.The locking mechanism can be configured so that the release of the push button 17, to allow its movement to the raised position, results from a tilting movement of the pushbutton 17 along an axis perpendicular to the path of movement of the pushbutton 17 during the transition from the raised position to the lowered position, this tilting movement of the push button 17 is obtained under the effect of an external tilting force applied to the push button 17 by the user. Since the situation of Figure 11 , the tilting has the effect of releasing the snap lug relative to the retaining catch, to allow the push button to return to the situation of the Figure 10 .

Le déplacement du bouton poussoir 17 de la position abaissée vers la position relevée est réalisé par l'action du ressort de serrage 15 durant son retour vers sa configuration active. Alternativement, il pourrait éventuellement être prévu un mécanisme de rappel du bouton poussoir 17 vers sa position relevée distinct du ressort de serrage 15.The movement of the pushbutton 17 from the lowered position to the raised position is achieved by the action of the clamping spring 15 during its return to its active configuration. Alternatively, it could optionally be provided a return mechanism of the push button 17 to its raised position separate from the clamping spring 15.

Selon un mode de réalisation sécuritaire et pratique, le boitier 11 et le bouton poussoir 17 délimitent respectivement des premiers éléments 22a et des seconds éléments 22b d'un même système de retenue, complémentaires et aptes à coopérer par encliquetage entre eux de sorte que le système de retenue assure une retenue du bouton poussoir 17 dans sa position relevée pour éviter une sortie du bouton poussoir 17 vers l'extérieur du boitier 11. A titre d'exemple simple et efficace, rendant le bouton poussoir 17 imperdable, les premiers éléments 22a sont constitués par un godron transversal solidaire du couvercle 11b, apte à coopérer par enclenchement avec une fente solidaire du bouton poussoir 17, cette fente visible sur les Figures 4, 10 et 11 étant constitutive des seconds éléments 22b du système de retenue.According to a safe and practical embodiment, the housing 11 and the push button 17 delimit respectively first elements 22a and second elements 22b of the same retaining system, complementary and able to cooperate by snapping between them so that the system retaining means ensures a retention of the pushbutton 17 in its raised position to avoid an output of the pushbutton 17 towards the outside of the housing 11. As a simple and effective example, making the pushbutton 17 captive, the first elements 22a are constituted by a transverse godron secured to the cover 11b, adapted to cooperate by engagement with a slot integral with the push button 17, this slot visible on the Figures 4 , 10 and 11 being constituent of the second elements 22b of the retaining system.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation représentés et décrits ci-avant, mais en couvre au contraire toutes les variantes.Of course, the invention is not limited to the embodiments shown and described above, but covers all variants.
