Description

L'invention concerne un contacteur à commande électromécanique, du type comportant, dans un boítier fixe :

  • au moins une paire de conducteurs portant chacun un contact fixe ;
  • au moins un pont de contact apte à occuper une position de fermeture dans laquelle il établit une connexion électrique entre les contacts fixes, et une position d'ouverture dans laquelle il se trouve à distance desdits contacts fixes ;
  • un ressort de contact associé audit pont de contact pour exercer, en position de fermeture, une pression entre ledit pont et lesdits contacts fixes ;
  • un électro-aimant comprenant :
    • une bobine ;
    • une armature fixe associée à ladite bobine ;
    • une armature mobile, située en regard de l'armature fixe, et apte à prendre une position de repos dans laquelle elle est située à distance d'entrefer de l'armature fixe, et une position de travail dans laquelle elle se trouve plaquée contre l'armature fixe, l'armature mobile étant sollicitée vers sa position de repos par un ressort de rappel ;
  • un actionneur couplé de façon bidirectionnelle à ladite armature mobile, ledit actionneur comportant :
    • une première surface de butée regardant vers l'armature mobile ;
    • une deuxième surface de butée regardant vers l'opposé de l'armature mobile ;
ledit actionneur étant adapté à entraíner ledit pont de contact vers sa position d'ouverture :
  • au moyen de la première surface de butée si ledit pont de contact est du type « à fermeture », c'est-à-dire agencé pour connecter les contacts fixes en position de travail de l'armature mobile ;
  • au moyen de la deuxième surface de butée et à l'encontre du ressort de rappel si ledit pont de contact est du type « à ouverture », c'est-à-dire agencé pour connecter les contacts fixes en position de repos de l'armature mobile.
The invention relates to an electromechanically controlled contactor, of the type comprising, in a fixed box:
  • at least one pair of conductors each carrying a fixed contact;
  • at least one contact bridge capable of occupying a closed position in which it establishes an electrical connection between the fixed contacts, and an open position in which it is spaced from said fixed contacts;
  • a contact spring associated with said contact bridge for exerting, in the closed position, pressure between said bridge and said fixed contacts;
  • an electromagnet comprising:
    • a coil ;
    • a fixed armature associated with said coil;
    • a movable frame, located opposite the fixed frame, and capable of assuming a rest position in which it is located at an air gap distance from the fixed frame, and a working position in which it is pressed against the fixed frame, the movable frame being biased towards its rest position by a return spring;
  • an actuator coupled bidirectionally to said movable armature, said actuator comprising:
    • a first abutment surface looking towards the movable frame;
    • a second abutment surface looking towards the opposite of the movable frame;
said actuator being adapted to drive said contact bridge towards its open position:
  • by means of the first abutment surface if said contact bridge is of the "closing" type, that is to say arranged to connect the fixed contacts in the working position of the movable frame;
  • by means of the second abutment surface and against the return spring if said contact bridge is of the “opening” type, that is to say arranged to connect the fixed contacts in the rest position of the movable frame.

Un contacteur de ce type est connu du document FR-2 756 092 au nom de la demanderesse. A contactor of this type is known from document FR-2 756 092 in the name of the plaintiff.

Bien que les contacteurs connus de ce type donnent entière satisfaction, l'on souhaite leur apporter quelque amélioration.Although known contactors of this type are entirely satisfactory, we wish to bring them some improvement.

En effet, qu'ils soient du type « à fermeture » ou du type « à ouverture », les ponts de contact sont embarqués sur l'actionneur avec leur ressort de contact.Indeed, whether they are of the “closing” type or of the “opening” type, the contact bridges are on board the actuator with their spring contact.

Le ressort de contact d'un pont de contact à ouverture agit donc à l'encontre du ressort de rappel de l'armature mobile puisqu'il la pousse vers sa position de travail tandis que le ressort de rappel la pousse vers sa position de repos.The contact spring of an opening contact bridge therefore acts against the return spring of the movable frame since it pushes it towards its working position while the return spring pushes it towards its working position rest.

Ceci nuit d'une part au bon positionnement de l'armature mobile en position de repos, et peut entraíner d'autre part un dysfonctionnement du contacteur en cas d'usure prématurée du ressort de rappel, l'armature mobile ayant alors des difficultés à retrouver sa position de repos.On the one hand, this affects the correct positioning of the movable frame in rest position, and can also cause malfunction of the contactor in the event of premature wear of the return spring, the movable armature then having difficulty finding its rest position.

Le document FR-2 652 947 prévoit de constituer un appui fixe pour les ressorts de contact au moyen d'une plaquette montée fixement dans le boítier.Document FR-2 652 947 provides for providing fixed support for contact springs by means of a plate fixedly mounted in the housing.

Cette disposition, dont la mise en oeuvre est délicate, bouleverserait l'agencement interne d'un contacteur du type décrit ci-dessus.This provision, the implementation of which is delicate, would upset the internal arrangement of a contactor of the type described above.

L'invention vise à fournir un contacteur du type prémentionné, qui soit à la fois fiable et de mise en oeuvre aisée, et qui fonctionne aussi bien avec des ponts de contact du type « à ouverture » qu'avec des ponts de contact du type « à fermeture ».The invention aims to provide a contactor of the aforementioned type, which is at the reliable and easy to use, and works equally well with contact bridges of the "opening" type only with contact bridges of the type "Closing".

A cet effet, l'invention propose un contacteur à commande électromécanique du type précité, caractérisé en ce que :

  • le boítier présente une surface d'appui regardant vers ladite armature mobile ;
  • il existe, entre cette surface d'appui et ladite deuxième surface de butée de l'actionneur, un espace libre adapté à recevoir un dit ressort de contact, avec celui-ci en appui d'une part contre un pont de contact à ouverture, et d'autre part contre la surface d'appui du boítier.
To this end, the invention proposes an electromechanical control contactor of the aforementioned type, characterized in that:
  • the housing has a bearing surface looking towards said movable frame;
  • there is, between this bearing surface and said second stop surface of the actuator, a free space adapted to receive a said contact spring, with the latter bearing on the one hand against an opening contact bridge, and on the other hand against the bearing surface of the housing.

Ce ressort de contact est ainsi indépendant de l'actionneur, de sorte qu'il n'agit pas à l'encontre du ressort de rappel en position de repos de l'armature mobile.This contact spring is thus independent of the actuator, so that it does not act against the return spring in rest position of the armature mobile.

Le contacteur est ainsi plus rapide, plus précis et plus fiable'. The contactor is thus faster, more precise and more reliable '.

Selon un mode de réalisation, l'actionneur comporte un bloc porte contact comportant au moins un compartiment susceptible de recevoir un pont de contact à fermeture.According to one embodiment, the actuator comprises a contact holder block comprising at least one compartment capable of receiving a closing contact.

Ce compartiment est délimité longitudinalement par deux faces transversales en regard, dont l'une forme ladite première surface de butée, tandis que l'autre forme une surface d'appui pour le ressort du pont de contact de sorte que l'ensemble pont de contact - ressort se trouve embarqué dans ledit bloc porte contact.This compartment is delimited longitudinally by two faces transverse facing, one of which forms said first abutment surface, while the other forms a bearing surface for the spring of the contact bridge so that the contact bridge - spring assembly is embedded in said contact holder block.

Le compartiment est par exemple fermé, du côté de ladite surface d'appui du boítier, par une cloison présentant deux faces opposées dont l'une, tournée vers l'intérieur du compartiment, forme la première surface de butée, tandis que l'autre forme la deuxième surface de butée.The compartment is for example closed, on the side of said bearing surface of the housing, by a partition having two opposite faces, one of which is turned towards the inside of the compartment, forms the first abutment surface, while the other forms the second abutment surface.

En outre, le bloc porte contact peut comporter un deuxième compartiment superposé au premier et séparé de lui par ladite cloison, ce deuxième compartiment étant susceptible de recevoir un pont de contact à ouverture.In addition, the contact block can include a second compartment superimposed on the first and separated from it by said partition, this second compartment capable of receiving an opening contact bridge.

Ce deuxième compartiment peut être séparé de ladite surface d'appui du boítier par une paroi dans laquelle est pratiqué un trou traversant formant un passage pour le ressort du pont de contact à ouverture.This second compartment can be separated from said bearing surface of the housing by a wall in which a through hole is formed forming a passage for the opening contact bridge spring.

De préférence, ce ressort présente, hors contrainte, un pas d'hélice dont la valeur est supérieure à celle de l'épaisseur de la paroi dans laquelle est pratiqué le trou traversant.Preferably, this spring has, without constraint, a propeller pitch of which the value is greater than that of the thickness of the wall in which is practiced the through hole.

Selon un autre mode de réalisation, l'actionneur comporte un bloc porte contact comportant au moins un compartiment susceptible de recevoir un pont de contact à fermeture ou un pont de contact à ouverture.According to another embodiment, the actuator comprises a door block contact comprising at least one compartment capable of receiving a bridge closing contact or opening contact bridge.

Ce compartiment est par exemple délimité longitudinalement par deux faces opposées dont l'une forme ladite première surface de butée et l'autre forme ladite deuxième surface de butée, ledit compartiment étant séparé de ladite surface d'appui du boítier par une paroi dont une face, tournée vers l'intérieur du compartiment, forme ladite première surface d'appui, et dans laquelle est pratiqué un trou traversant formant un passage pour le ressort du pont de contact à ouverture.This compartment is for example delimited longitudinally by two opposite faces, one of which forms said first abutment surface and the other forms said second abutment surface, said compartment being separated from said bearing surface of the housing by a wall including one face, facing inside the compartment, forms said first bearing surface, and in which is made a through hole forming a passage for the spring of the opening contact bridge.

Par exemple, l'actionneur est à section en forme de U encadrant l'armature fixe, et comporte une base transversale formant ledit bloc porte contact, ainsi que deux branches longitudinales en regard, saillant du bloc porte contact, et fixée chacune par une extrémité à ladite armature mobile.For example, the actuator has a U-shaped section framing the fixed frame, and has a transverse base forming said door block contact, as well as two facing longitudinal branches, projecting from the door unit contact, and each fixed by one end to said movable frame.

Par ailleurs, et selon un mode de réalisation, le ressort de rappel est situé entre le bloc porte contact et le boítier, sur lesquels il prend appui.Furthermore, and according to one embodiment, the return spring is located between the contact block and the housing, on which it is supported.

De préférence, le ressort de rappel prend appui sur la surface d'appui du boítier.Preferably, the return spring bears on the bearing surface of the housing.

Par exemple, le ressort de rappel est d'une part inséré dans un puits du bloc porte contact, et d'autre part emmanché sur un téton saillant du boítier.For example, the return spring is on the one hand inserted into a well of the contact holder block, and on the other fitted onto a protruding stud of the housing.

Selon un mode de réalisation, ce puits se trouve entre deux porte contact du bloc porte contact, chaque porte contact comportant au moins un compartiment tel que décrit ci-dessus.According to one embodiment, this well is located between two contact carriers of the contact holder block, each contact holder comprising at least one compartment as described above.

Sur les figures est représenté un contacteur 1 à commande électromécanique du type conçu notamment pour connecter au réseau de distribution électrique un appareil électrique (non représenté).In the figures is shown a control switch 1 electromechanical of the type designed in particular to connect to the electrical distribution an electrical appliance (not shown).

Le contacteur 1 comporte un boítier 2 dans lequel est logé un électro-aimant 3 dont l'alimentation pilote le fonctionnement de l'appareil électrique.The contactor 1 comprises a housing 2 in which is housed an electromagnet 3, the power supply of which controls the operation of the electrical appliance.

Le boítier 2 comprend un corps de boítier 4 destiné à être fixé de manière amovible sur un rail d'une armoire électrique (non représentés) au moyen d'un système d'accrochage composé d'une paire de griffes 5, 6 en regard, dont l'une 5 au moins est coulissante, et est sollicitée vers l'autre 6 par un ressort de rappel 7. Le boítier 2 comprend en outre un couvercle 8 qui surmonte le corps de boítier 4 en étant à la fois emboíté et encliqueté dans celui-ci. Le couvercle 8 est en forme de chapeau et présente un nez 9 destiné à être engagé dans la fenêtre d'un plastron (non représenté) de l'armoire électrique, pour ménager un accès au moins visuel au contacteur 1.The housing 2 comprises a housing body 4 intended to be fixed so removable on a rail of an electrical cabinet (not shown) by means of a hanging system composed of a pair of claws 5, 6 facing each other, one of which 5 at least is sliding, and is biased towards the other 6 by a return spring 7. The housing 2 further comprises a cover 8 which surmounts the housing body 4 being both fitted and snapped into it. The cover 8 is in hat shape and has a nose 9 intended to be engaged in the window a faceplate (not shown) of the electrical cabinet, to provide access to the less visible to contactor 1.

L'électro-aimant 3 comprend d'une part, une partie fixe 10 incluant une bobine 11 supportée par une carcasse 12 fixée au boítier 2 ainsi qu'une armature fixe 13 associée à la bobine 11, et, d'autre part, une armature mobile 14 située en regard de l'armature fixe 13.The electromagnet 3 comprises on the one hand, a fixed part 10 including a coil 11 supported by a carcass 12 fixed to the housing 2 and a fixed armature 13 associated with the coil 11, and, on the other hand, a movable armature 14 located opposite the fixed frame 13.

L'armature mobile 14 est apte à prendre une position de repos (figures 2, 3, 6, 8, 9, 12, 14) dans laquelle elle est écartée de l'armature fixe 13 en étant située à distance d'entrefer de celle-ci, et une position de travail (figures 4, 5, 7, 10, 11, 13) dans laquelle elle se trouve plaquée contre l'armature fixe 13. L'armature mobile 14 est sollicitée vers sa position de repos par un ressort de rappel 15 qui prend appui contre le corps de boítier 4.The movable frame 14 is able to assume a rest position (FIGS. 2, 3, 6, 8, 9, 12, 14) in which it is separated from the fixed frame 13 by being located at an air gap therefrom, and a working position (FIGS. 4, 5, 7, 10, 11, 13) in which it is pressed against the fixed frame 13. The movable armature 14 is biased towards its rest position by a spring reminder 15 which bears against the housing body 4.

En position de repos, l'armature mobile 14 se trouve escamotée dans le nez 9 du couvercle 8, qui forme ainsi un logement pour la recevoir (figures 2, 8).In the rest position, the movable armature 14 is retracted into the nose 9 of cover 8, which thus forms a housing for receiving it (FIGS. 2, 8).

Un actionneur 16 se trouve couplé à l'armature mobile 14 pour entraíner un pont de contact 17, 17' apte à établir une liaison électrique entre un premier et un deuxième conducteurs 18, 19, montés dans le corps de boítier 4, et situés en regard.An actuator 16 is coupled to the movable frame 14 to drive a contact bridge 17, 17 ′ capable of establishing an electrical connection between a first and a second conductor 18, 19, mounted in the housing body 4, and located opposite.

Tel qu'il apparaít sur la figure 1, le contacteur 1, du type bipolaire, comprend deux premiers conducteurs 18 et deux deuxièmes conducteurs 19.As it appears in FIG. 1, the contactor 1, of the bipolar type, comprises two first conductors 18 and two second conductors 19.

Pour sa connexion au réseau électrique, le contacteur 1 comporte deux premières bornes de puissance 20 disposées d'un même côté du boítier 2, et dont l'une est destinée à raccorder l'un des premiers conducteurs 18 à un pôle du réseau, tandis que l'autre est destinée à raccorder l'autre premier conducteur 18 à un autre pôle du réseau.For its connection to the electrical network, the contactor 1 comprises two first power terminals 20 disposed on the same side of the housing 2, and one of which is intended to connect one of the first conductors 18 to a pole of the network, while the other is intended to connect the other first conductor 18 to another pole of the network.

Deux deuxièmes bornes de puissance 21 sont également prévues pour raccorder de la même manière les deuxièmes conducteurs 19 à l'appareil électrique.Two second power terminals 21 are also provided for similarly connect the second conductors 19 to the device electric.

Tel qu'il apparaít sur la figure 1, chaque borne de puissance 20, 21 est agencée pour pincer un fil électrique dénudé du réseau électrique.As it appears in Figure 1, each power terminal 20, 21 is arranged to pinch a bare electrical wire from the electrical network.

A cet effet, chaque borne 20, 21 comporte un élément de connexion mobile 22 monté coulissant dans le corps de boítier 4, le coulissement de cet élément 22 étant commandé par une vis de serrage 23 engagée dans un trou 24 du couvercle 8, et qui, prenant appui sur le conducteur 18, 19, provoque par sa rotation le pincement du fil dénudé entre l'élément de connexion 22 et le conducteur 18, 19, sur lequel est engagé l'élément de connexion 22.For this purpose, each terminal 20, 21 has a connection element mobile 22 slidably mounted in the housing body 4, the sliding of this element 22 being controlled by a clamping screw 23 engaged in a hole 24 of the cover 8, and which, bearing on the conductor 18, 19, causes by its rotation the pinching of the bare wire between the connection element 22 and the conductor 18, 19, on which the connection element 22 is engaged.

Chaque borne de puissance 20, 21 est montée dans le corps de boítier 4 en regard d'une fenêtre 25 pratiquée dans celui-ci pour le passage du fil dénudé correspondant du réseau électrique.Each power terminal 20, 21 is mounted in the housing body 4 next to a window 25 made therein for the passage of the bare wire electrical network correspondent.

Afin de détromper l'utilisateur du contacteur 1 lors de la connexion de celui-ci au réseau ou à l'appareil électrique, l'élément de connexion 22 présente une saillie 26 formant un volet susceptible d'obturer la fenêtre 25 lors du coulissement de l'élément 22 (figure 2). In order to confuse the user of contactor 1 when connecting this to the network or to the electrical device, the connection element 22 has a projection 26 forming a flap capable of closing the window 25 during sliding of element 22 (FIG. 2).

Le contacteur 1 comprend en outre deux bornes de commande 27 pour le raccordement de la bobine à un circuit de commande d'alimentation de celle-ci.The contactor 1 further comprises two control terminals 27 for the connection of the coil to a supply control circuit thereof.

Chaque premier conducteur 18 présente une partie extrême 28 dont le bout porte ou forme un contact fixe 29, tandis que chaque deuxième conducteur 19 présente une partie extrême 30 disposée en regard de la partie extrême 28 du premier conducteur 18, cette partie extrême 30 portant ou formant également un contact fixe 31.Each first conductor 18 has an end portion 28, the door end or forms a fixed contact 29, while each second conductor 19 has an end portion 30 disposed opposite the end portion 28 of the first conductor 18, this end portion 30 also carrying or forming a fixed contact 31.

Chaque pont de contact 17, 17' se présente quand à lui sous la forme d'une lamelle conductrice dont les bouts portent ou forment un contact mobile 32, 33 susceptible d'être appliqué contre un contact fixe 29, 31 pour relier entre eux les conducteurs 18, 19.Each contact bridge 17, 17 'is in the form of a conductive strip whose ends carry or form a movable contact 32, 33 can be applied against a fixed contact 29, 31 to connect between them the conductors 18, 19.

Le pont de contact 17, 17' est apte à occuper une position de fermeture dans laquelle il établit une connexion électrique entre les contacts fixes 29, 31 par l'intermédiaire, respectivement, des contacts mobiles 32, 33, et une position d'ouverture dans laquelle il se trouve à distance des conducteurs 18, 19, ces contacts mobiles 32, 33 étant alors écartés des contacts fixes 29, 31.The contact bridge 17, 17 'is able to occupy a closed position in which it establishes an electrical connection between the fixed contacts 29, 31 via, respectively, movable contacts 32, 33, and a position opening in which it is remote from the conductors 18, 19, these movable contacts 32, 33 then being spaced from the fixed contacts 29, 31.

Les positions du pont de contact 17, 17' sont commandées par l'électro-aimant 3, et plus spécifiquement par le mouvement de l'armature mobile 14.The positions of the contact bridge 17, 17 'are controlled by the electromagnet 3, and more specifically by the movement of the movable armature 14.

On distingue deux modes de fonctionnement du contacteur 1, à savoir un mode de fonctionnement dit « à fermeture », et un mode de fonctionnement dit « à ouverture ».There are two operating modes of contactor 1, namely a operating mode called "closing", and operating mode called "Open".

Dans le mode de fonctionnement du type à fermeture, le pont de contact 17 est agencé pour occuper sa position de fermeture, c'est-à-dire connecter les contacts fixes 29, 31, en position de travail de l'armature mobile 14, tel qu'il apparaít sur les figures 4 et 5, ainsi que sur la figure 7. Un tel pont de contact 17 est dit du type « à fermeture ».In the closing type operating mode, the contact bridge 17 is arranged to occupy its closed position, that is to say connect the fixed contacts 29, 31, in the working position of the movable armature 14, as it appears in Figures 4 and 5, as well as in Figure 7. Such a contact bridge 17 is said to be of the "closing" type.

En position de repos de l'armature mobile 14, le pont de contact 17 occupe sa position d'ouverture, tel qu'il apparaít sur les figures 2 et 3, ainsi que sur la figure 6.In the rest position of the movable armature 14, the contact bridge 17 occupies its open position, as it appears in Figures 2 and 3, as well as in figure 6.

En position de travail de l'armature mobile 14, le pont de contact 17 occupe sa position de fermeture, tel qu'il apparaít sur les figures 4, 5, ainsi que sur la figure 7. In the working position of the movable armature 14, the contact bridge 17 occupies its closed position, as it appears in FIGS. 4, 5, as well as in figure 7.

Dans le mode de fonctionnement à ouverture, le pont de contact, référencé 17' à des fins de clarté, est agencé pour occuper sa position de fermeture, c'est-à-dire pour connecter les contacts fixes 29, 31, en position de repos de l'armature mobile 14, tel qu'il apparaít sur les figures 8 et 9, ainsi que sur la figure 12. Un tel pont de contact 17' est dit du type « à ouverture ».In the opening operating mode, the contact bridge, referenced 17 'for clarity, is arranged to occupy its position of closing, that is to say to connect the fixed contacts 29, 31, in the position of rest of the movable armature 14, as it appears in FIGS. 8 and 9, as well as in FIG. 12. Such a contact bridge 17 ′ is said to be of the “opening” type.

En position de travail de l'armature mobile 14, le pont de contact 17' occupe sa position d'ouverture, tel qu'il apparaít sur les figures 10 et 11, ainsi que sur la figure 13.In the working position of the movable armature 14, the contact bridge 17 ' occupies its open position, as it appears in Figures 10 and 11, as well as in Figure 13.

Le contacteur 1 est agencé pour fonctionner tant à l'ouverture qu'à la fermeture, tel qu'il ressort de ce qui va suivre.The contactor 1 is arranged to operate both when opening and when closure, as shown in what follows.

L'actionneur 16 présente une section en forme de U et comprend une base transversale formant un bloc porte contact 34 dont saillent deux branches parallèles en regard 35 qui présentent chacune une extrémité 36 engagée sur le bout d'une tige 37 transversale passant dans un alésage de l'armature mobile 14, de sorte que l'actionneur 16 se trouve couplé à l'armature mobile 14.The actuator 16 has a U-shaped section and includes a transverse base forming a contact carrier block 34 of which project two branches opposite parallels 35 which each have one end 36 engaged on the end of a transverse rod 37 passing through a bore of the movable frame 14, so that the actuator 16 is coupled to the movable armature 14.

Le bloc porte contact 34 comprend deux porte contact 38 jumelés situés sensiblement dans le prolongement des branches 35.The contact holder block 34 includes two paired contact holders 38 located substantially in the extension of the branches 35.

Chaque porte contact 38 comprend deux compartiments superposés, à savoir un compartiment supérieur 39 adapté à recevoir un pont de contact 17 du type à fermeture, ainsi qu'un compartiment inférieur 40 adapté à recevoir un pont de contact 17' du type à ouverture.Each contact carrier 38 comprises two superimposed compartments, know an upper compartment 39 adapted to receive a contact bridge 17 of the closing type, as well as a lower compartment 40 adapted to receive a bridge contact type 17 'of the opening type.

Le compartiment supérieur 39 et le compartiment inférieur 40 sont séparés l'un de l'autre par une cloison 41 présentant deux faces opposées formant respectivement une première surface de butée 42 regardant vers l'armature mobile 14, et une deuxième surface de butée 43 regardant vers l'opposé.The upper compartment 39 and the lower compartment 40 are separated from each other by a partition 41 having two opposite faces respectively forming a first abutment surface 42 looking towards the movable frame 14, and a second abutment surface 43 looking towards the opposite.

Le compartiment supérieur 39 est délimité longitudinalement d'une part par la première surface de butée 42, d'autre part par une face transversale 44 en regard de celle-ci, et, transversalement, par deux parois supérieures 75, longitudinales, en regard.The upper compartment 39 is delimited longitudinally on the one hand by the first abutment surface 42, on the other hand by a transverse face 44 in look of it, and, transversely, by two upper walls 75, longitudinal, opposite.

En mode de fonctionnement à fermeture, un pont de contact 17 du type à fermeture se trouve inséré dans le compartiment supérieur 39 en étant sollicité vers sa position de fermeture par un ressort de contact 45 fonctionnant à la compression, qui lui est associé, et qui prend appui d'une part sur le pont de contact 17, et d'autre part contre la face transversale 44, de sorte que l'ensemble pont de contact 17- ressort 45 se trouve embarqué dans le bloc porte contact 34.In closing operating mode, a contact bridge 17 of the type closure is inserted in the upper compartment 39 when requested towards its closed position by a contact spring 45 operating at the compression, which is associated with it, and which rests on the one hand on the bridge of contact 17, and on the other hand against the transverse face 44, so that the assembly contact bridge 17- spring 45 is embedded in the contact holder block 34.

Afin d'éviter tout débattement du ressort de contact 45, son extrémité située du côté de la face transversale 44 est emmanchée sur un téton 76 saillant de celle-ci, tandis que son extrémité opposée est logée dans une réserve en creux 77 ménagée dans le pont de contact 17, en s'y trouvant maintenue par l'intermédiaire des parois supérieures 75.In order to avoid any movement of the contact spring 45, its end located on the side of the transverse face 44 is fitted onto a protruding stud 76 of it, while its opposite end is housed in a reserve in hollow 77 formed in the contact bridge 17, while being held there by through the upper walls 75.

Accompagnant l'armature mobile 14, le bloc porte contact 34 se déplace longitudinalement dans un espace 46 ménagé entre, d'une part l'électro-aimant 3, plus particulièrement l'armature fixe 13, et d'autre part une paroi de fond 47 du corps de boítier 4.Accompanying the movable frame 14, the contact block 34 moves longitudinally in a space 46 formed between, on the one hand the electromagnet 3, more particularly the fixed frame 13, and on the other hand a bottom wall 47 of the body 4.

En position de travail de l'armature mobile 14, tel qu'il apparaít sur les figures 4, 5, 7, le pont de contact 17 se trouve plaqué contre les conducteurs 18,19 et maintenu dans cette position par l'intermédiaire du ressort de contact 45 qui se trouve comprimé entre le pont de contact 17 et la face 44.In the working position of the movable frame 14, as it appears on the Figures 4, 5, 7, the contact bridge 17 is pressed against the conductors 18.19 and held in this position by means of the contact spring 45 which is compressed between the contact bridge 17 and the face 44.

Lorsque l'armature mobile 14 reprend sa position de repos, vers laquelle elle est sollicitée par le ressort de rappel 15, le pont de contact 17 se trouve décollé du conducteur 18, 19 en étant entraíné vers sa position d'ouverture par l'actionneur 16, au moyen de la première surface de butée 42, contre laquelle se trouve plaqué le pont de contact 17 par la détente du ressort de contact 45 (figures 2, 3, 6).When the movable armature 14 returns to its rest position, towards which it is stressed by the return spring 15, the contact bridge 17 is located detached from the conductor 18, 19 while being driven towards its open position by the actuator 16, by means of the first abutment surface 42, against which is is placed against the contact bridge 17 by the trigger of the contact spring 45 (Figures 2, 3, 6).

Le compartiment inférieur 40 est quant à lui délimité longitudinalement, d'une part par la cloison 41, et d'autre part par une paroi 48 sensiblement parallèle à la cloison 41, formant une extrémité libre de l'actionneur 16, et séparant le compartiment inférieur 40 de la paroi de fond 47. Le compartiment inférieur 40 est délimité transversalement par deux parois inférieures 78, longitudinales, en regard.The lower compartment 40 is delimited longitudinally, on the one hand by the partition 41, and on the other hand by a wall 48 substantially parallel to the partition 41, forming a free end of the actuator 16, and separating the lower compartment 40 from the bottom wall 47. The compartment lower 40 is delimited transversely by two lower walls 78, longitudinal, opposite.

Dans le mode de fonctionnement à ouverture du contacteur 1, un pont de contact 17' à ouverture se trouve inséré dans le compartiment inférieur 40.In the operating mode with contactor 1 opening, a bridge contact 17 'with opening is inserted in the lower compartment 40.

En position de repos de l'armature mobile 14, tel qu'il apparaít sur les figures 8, 9, 12, le pont de contact 17' se trouve collé contre les conducteurs 18, 19 en étant maintenu dans cette position par un ressort de contact 49 à compression qui prend appui d'une part sur le pont de contact 17', et d'autre part sur une surface d'appui 50 de la paroi de fond 47 du corps de boítier 4, tournée vers l'armature mobile 14.In the rest position of the movable frame 14, as it appears on the FIGS. 8, 9, 12, the contact bridge 17 ′ is glued against the conductors 18, 19 while being held in this position by a contact spring 49 to compression which is supported on the one hand on the contact bridge 17 ', and on the other hand on a bearing surface 50 of the bottom wall 47 of the housing body 4, turned to the movable frame 14.

Afin de permettre cette disposition, il existe entre la deuxième surface de butée 43 et cette surface d'appui 50 un espace adapté à recevoir le ressort de contact 49.In order to allow this arrangement, there is between the second surface of stop 43 and this bearing surface 50 a space adapted to receive the spring contact 49.

Il est ainsi pratiqué dans la paroi 48 du compartiment inférieur 40, un trou traversant 51 dans lequel est engagé le ressort de contact 49, de sorte que celui-ci ne se trouve pas embarqué dans le bloc porte contact 34, mais est indépendant de ce dernier.It is thus made in the wall 48 of the lower compartment 40, a hole through 51 in which is engaged the contact spring 49, so that this is not on board the contact holder block 34, but is independent of the latter.

Ainsi, en position de repos, l'armature mobile 14 ne se trouve sollicitée vers cette position que par son ressort de rappel 15.Thus, in the rest position, the movable armature 14 is not stressed towards this position only by its return spring 15.

Lorsque l'armature mobile 14 passe dans sa position de travail, tel qu'il apparaít sur les figures 10, 11, 13, l'actionneur 16 entraíne le pont de contact 17' vers sa position d'ouverture à l'encontre de son ressort de contact 49, au moyen de la deuxième surface de butée 43 et à l'encontre du ressort de rappel 15.When the movable armature 14 passes into its working position, as it appears in Figures 10, 11, 13, the actuator 16 drives the contact bridge 17 ' towards its open position against its contact spring 49, by means of the second abutment surface 43 and against the return spring 15.

La paroi 48 permet notamment de rigidifier le bloc porte contact 34, tandis que le trou traversant 51, qui présente ici un diamètre légèrement supérieur à celui du ressort 49, permet d'éviter toute flexion et tout échappement intempestif de celui-ci.The wall 48 makes it possible in particular to stiffen the contact holder block 34, while that the through hole 51, which here has a diameter slightly greater than that of the spring 49, makes it possible to avoid any bending and any untimely escape of it.

Et, afin d'éviter tout débattement du ressort de contact 49, son extrémité située du côté de la paroi de fond 47 est emmanchée sur un pion 52 saillant de la paroi de fond 47 du corps de boítier 4 (figures 8, 9), tandis que son extrémité opposée est logée dans la réserve en creux 77 ménagée dans le pont de contact 17', en s'y trouvant maintenue par l'intermédiaire des parois inférieures 78.And, in order to avoid any movement of the contact spring 49, its end located on the side of the bottom wall 47 is fitted on a pin 52 projecting from the bottom wall 47 of the housing body 4 (Figures 8, 9), while its end opposite is housed in recess 77 formed in the contact bridge 17 ', while being held there by means of the lower walls 78.

Par ailleurs, le ressort 49 présente, hors contrainte, un pas d'hélice, c'est-à-dire une distance entre deux spires successives, de valeur inférieure à celle de l'épaisseur de la cloison 48, de sorte à éviter tout risque d'engagement du ressort 49 avec la cloison 48 entre deux spires successives.Furthermore, the spring 49 has, without stress, a propeller pitch, that is to say a distance between two successive turns, of value less than that of the thickness of the partition 48, so as to avoid any risk of engagement of the spring 49 with the partition 48 between two successive turns.

L'on décrit à présent l'électro-aimant 3 de manière plus détaillée.The electromagnet 3 will now be described in more detail.

La carcasse 12 est à section sensiblement en forme de I, et comprend un socle 54 ainsi qu'un plateau 55 reliés par une âme centrale 56 creuse autour de laquelle est enroulée la bobine 11 qui se trouve emprisonnée entre le socle 54 et le plateau 55.The carcass 12 is of substantially I-shaped section, and comprises a base 54 and a plate 55 connected by a central core 56 hollow around which is wound the coil 11 which is trapped between the base 54 and the plate 55.

Chaque armature 13, 14 présente une section en forme de E, et présente deux branches d'extrémité 57 encadrant la bobine 11 et sa carcasse 12, ainsi qu'une branche centrale 58 engagée à l'intérieur de l'âme 56.Each frame 13, 14 has an E-shaped section, and has two end branches 57 framing the coil 11 and its carcass 12, thus that a central branch 58 engaged inside the core 56.

La carcasse 12 comporte quatre pieds 59 qui saillent du socle 54 en direction de la paroi de fond 47 du corps de boítier 4.The carcass 12 has four feet 59 which project from the base 54 in direction of the bottom wall 47 of the housing body 4.

Ce dernier comprend quant à lui quatre pattes 60, disposées en regard des pieds 59. Les pattes 60 saillent de la paroi de fond 47 avec laquelle ils sont venus de matière, en direction de la carcasse 12.The latter includes four legs 60, arranged opposite feet 59. The legs 60 project from the bottom wall 47 with which they are coming from material, towards the carcass 12.

La partie extrême 30, 31 de chaque conducteur 18, 19 se trouve immobilisée en étant serrée, à proximité du contact fixe 29, 31, entre une première mâchoire appartenant au boítier 2 et formée par l'une des pattes 60, et une deuxième mâchoire appartenant à la carcasse 12, et formée par le pied 59 correspondant.The extreme part 30, 31 of each conductor 18, 19 is located immobilized by being clamped, near the fixed contact 29, 31, between a first jaw belonging to the housing 2 and formed by one of the legs 60, and a second jaw belonging to the carcass 12, and formed by the foot 59 corresponding.

L'assemblage de la carcasse 12 au corps de boítier 4 et le serrage des parties extrêmes 28, 30 des conducteurs 18, 19 sont assurés par deux vis 61.The assembly of the carcass 12 to the housing body 4 and the tightening of end portions 28, 30 of the conductors 18, 19 are secured by two screws 61.

Chaque vis 61 est insérée dans un trou traversant 62 pratiqué dans la paroi de fond 47 du corps de boítier 4, et formant un passage pour la vis 61, celle-ci étant par ailleurs engagée dans un alésage fileté 63 du socle 54, situé en regard du trou traversant 62 et coaxial avec celui-ci.Each screw 61 is inserted into a through hole 62 made in the bottom wall 47 of the housing body 4, and forming a passage for the screw 61, the latter being also engaged in a threaded bore 63 of the base 54, located in look of the through hole 62 and coaxial with it.

Afin d'assurer le guidage de la vis lors de l'assemblage de la carcasse 12 au corps de boítier 4, le trou traversant 62 est pratiqué dans une cheminée 64 saillant de la paroi de fond 47 vers la carcasse 12.To guide the screw during assembly of the carcass 12 to the housing body 4, the through hole 62 is made in a chimney 64 projecting from the bottom wall 47 towards the carcass 12.

L'alésage 63 est quant à lui pratiqué dans un fût 65 saillant du socle 54 vers la paroi de fond 47, en regard de la cheminée 64.The bore 63 is made in a barrel 65 projecting from the base 54 towards the bottom wall 47, facing the chimney 64.

Lorsque la carcasse 12 se trouve assemblée au corps de boítier 4, les parties extrêmes 28, 30 des conducteurs 18, 19 étant disposées entre les mâchoires 59, 60, il existe entre le corps de boítier 4 et la carcasse 12, au niveau de la vis 61, un jeu J apte à permettre le serrage des parties extrêmes 28, 30 entre les mâchoires 59, 60 au moyen des vis 61. When the carcass 12 is assembled to the housing body 4, the end portions 28, 30 of the conductors 18, 19 being arranged between the jaws 59, 60, there are between the housing body 4 and the carcass 12, at level of the screw 61, a clearance J suitable for allowing the tightening of the end parts 28, 30 between the jaws 59, 60 by means of the screws 61.

Ici, le jeu J est la distance qui sépare la cheminée 64 du fût 65 lorsque l'assemblage de la carcasse 12 au corps de boítier 4 est réalisé, au moins avant que ne soit réalisé le serrage des conducteurs 18, 19.Here, the clearance J is the distance which separates the chimney 64 from the barrel 65 when assembly of the carcass 12 to the housing body 4 is carried out, at least before that the conductors 18, 19 are not tightened.

En outre, afin de maintenir sur les vis 61 une tension permettant d'éviter leur desserrage, la paroi de fond 47 présente une capacité à fléchir lors du serrage des vis 61, en direction de la carcasse 12.In addition, in order to maintain a tension on the screws 61 making it possible to avoid their loosening, the bottom wall 47 has a capacity to flex during tightening the screws 61, towards the carcass 12.

Ainsi, par son élasticité propre, la paroi de fond 47 exerce sur les vis 61 une traction qui freine leur libre rotation.Thus, by its own elasticity, the bottom wall 47 exerts on the screws 61 a traction which slows down their free rotation.

Lorsque le serrage des conducteurs 18, 19 est réalisé, le jeu J peut s'annuler, notamment par flexion de la paroi de fond 47, la cheminée 64 et le fût 65 venant alors en contact. On évite ainsi un serrage trop fort des vis 61, qui pourrait endommager, voire briser le corps de boítier 4.When the conductors 18, 19 are tightened, the clearance J can cancel each other out, in particular by bending the bottom wall 47, the chimney 64 and the barrel 65 then coming into contact. This prevents excessive tightening of the screws 61, which could damage or even break the housing body 4.

Par ailleurs, l'actionneur 16 est guidé dans son mouvement par des rainures prévues à cet effet dans le corps de boítier, tandis qu'il est sollicité vers la position de repos par le ressort de rappel 15 qui se trouve comprimé, dans l'espace 46, entre le bloc porte contact 34 et la paroi de fond 47 du corps de boítier 4.Furthermore, the actuator 16 is guided in its movement by grooves provided for this purpose in the housing body, while it is biased towards the rest position by the return spring 15 which is compressed, in the space 46, between the contact carrier block 34 and the bottom wall 47 of the body housing 4.

Afin d'assurer son guidage, le ressort de rappel 15 est d'une part inséré dans l'alésage d'un puits cylindrique 66 réalisé dans le bloc porte contact 34 et situé entre les porte contact 38.To ensure its guidance, the return spring 15 is firstly inserted in the bore of a cylindrical well 66 produced in the contact holder block 34 and located between contact holders 38.

Le ressort de rappel 15 est d'autre part emmanché sur un téton 53 formant une butée pour le ressort 15, et saillant de la paroi de fond 47 avec laquelle il est venu de matière.The return spring 15 is on the other hand fitted onto a stud 53 forming a stop for the spring 15, and projecting from the bottom wall 47 with which it came from.

Le contacteur 1 comporte d'autres éléments constitutifs, que l'on décrit succinctement à présent.The contactor 1 comprises other constituent elements, which are described succinctly now.

Il est prévu, entre autres, une platine 67 encliquetée dans le corps de boítier 4, sur laquelle est monté coulissant un poussoir 68 mobile entre trois positions stables, à savoir une position de fonctionnement automatique, une position de fonctionnent forcé, ainsi qu'une position de mise hors service.Among other things, there is provided a plate 67 snapped into the body of case 4, on which is slidably mounted a pusher 68 movable between three stable positions, i.e. an automatic operating position, a forced operation position, as well as a deactivation position.

La platine 67 forme également un guide pour un levier 69 dont une extrémité est emmanchée sur la tige 37, tandis que l'autre extrémité forme un voyant 70 escamotable susceptible d'apparaítre ou de disparaítre, suivant la position de l'armature mobile 14, en regard d'une fenêtre 71 obturée par un volet 72 permettant un accès au poussoir 68.The plate 67 also forms a guide for a lever 69, one of which end is fitted onto rod 37, while the other end forms a retractable indicator 70 capable of appearing or disappearing, depending on the position of the movable frame 14, opposite a window 71 closed by a flap 72 allowing access to the pusher 68.

Par ailleurs, le socle 54 de la carcasse 12 présente, entre deux pieds 59 adjacents situés d'un même côté du socle 54, un logement 73 dans lequel est introduite l'armature fixe 13.Furthermore, the base 54 of the carcass 12 has, between two feet 59 adjacent located on the same side of the base 54, a housing 73 in which is introduced the fixed frame 13.

Ce logement 73 présente une surface de butée 74 transversale étendue entre les pieds 59, regardant vers la paroi de fond 47 du corps de boítier 4, et contre laquelle est plaquée l'armature fixe 13 en position de travail de l'armature 14.This housing 73 has an extended transverse abutment surface 74 between the feet 59, looking towards the bottom wall 47 of the housing body 4, and against which the fixed frame 13 is pressed in the working position of the frame 14.

Par contre, en position de repos de cette dernière, il existe un jeu entre l'armature fixe 13 et cette surface de butée 73, tandis que le bloc porte contact 34 se trouve plaqué contre une nervure 79 du socle 54 (figures 6, 15 notamment).On the other hand, in the latter's rest position, there is a clearance between the fixed armature 13 and this abutment surface 73, while the contact-carrying block 34 is pressed against a rib 79 of the base 54 (Figures 6, 15 especially).

Selon une première variante de réalisation non illustrée, chaque porte contact 38 comprend un unique compartiment du type du compartiment inférieur 40 décrit ci-dessus et adapté à recevoir aussi bien un pont de contact du type à fermeture qu'un pont de contact du type à ouverture.According to a first alternative embodiment not shown, each door contact 38 includes a single compartment of the lower compartment type 40 described above and adapted to receive both a contact bridge of the type to closing than an opening type contact bridge.

Dans ce cas, la première surface de butée 42 est portée par la paroi 48 du compartiment, tandis que la deuxième surface de butée 43 est formée par une face transversale supérieure du compartiment, en regard de la première surface de butée 42.In this case, the first abutment surface 42 is carried by the wall 48 of the compartment, while the second abutment surface 43 is formed by an upper transverse face of the compartment, opposite the first abutment surface 42.

Par ailleurs, il est possible, selon la configuration du contacteur 1, de n'employer qu'une seule vis de serrage 61, ou d'en employer un nombre strictement supérieur à deux.Furthermore, it is possible, depending on the configuration of the contactor 1, to use only one clamping screw 61, or use a number strictly greater than two.

En outre, afin de simplifier la fabrication du contacteur 1, il peut être avantageux de réaliser le filetage de l'alésage 63 lors de l'assemblage, au moyen de la vis 61 elle-même, cette dernière exerçant alors une fonction supplémentaire de taraud.In addition, in order to simplify the manufacture of the contactor 1, it can be advantageous to produce the thread of the bore 63 during assembly, at by means of the screw 61 itself, the latter then exercising a function additional tap.

Et, selon une deuxième variante de réalisation non représentée, il est également possible de remplacer les vis 61 par d'autres moyens de serrage analogues permettant d'aboutir au même résultat. On pourra notamment employer des rivets ou des clous. And, according to a second variant embodiment not shown, it is also possible to replace screws 61 by other tightening means analogues to achieve the same result. We can in particular use rivets or nails.

Selon une troisième variante de réalisation, les conducteurs se trouvent immobilisés en étant serrés entre les mâchoires 59, 60, ailleurs qu'au niveau de leurs extrémités, selon la configuration du contacteur, la forme ou la disposition des conducteurs.According to a third alternative embodiment, the conductors are found immobilized by being clamped between the jaws 59, 60, elsewhere than at their ends, depending on the configuration of the contactor, shape or arrangement conductors.

Selon une quatrième variante non représentée, le contacteur est multipolaire, par exemple du type quadripolaire, le bloc porte contact comprenant à cet effet deux paires de porte contact, l'une de ces paires fonctionnant par exemple à l'ouverture, tandis que l'autre de ces paires fonctionne à la fermeture.According to a fourth variant not shown, the contactor is multipolar, for example of the quadrupole type, the contact block comprising for this purpose two pairs of contact carriers, one of these pairs operating by example on opening, while the other of these pairs works on closing.

Il est bien entendu possible de combiner entre elles les différentes variantes sans sortir du cadre de l'invention.It is of course possible to combine the different variants without departing from the scope of the invention.
