Description

La présente invention concerne un contacteur électromécanique comportant un corps qui est doté d'éléments de fixation à un support et loge un électroaimant et un porte-contacts mobile, l'électroaimant comprenant une bobine, une armature fixe et une armature mobile apte à déplacer le porte-contacts, le corps comprenant des bornes de puissance et des bornes de commande.The present invention relates to an electromechanical contactor comprising a body which is provided with fasteners to a support and houses an electromagnet and a movable contact carrier, the electromagnet comprising a coil, a fixed armature and a movable armature adapted to move the contact carrier, the body comprising power terminals and control terminals.

Il convient de rappeler que les bornes de puissance du corps sont reliées par des pièces conductrices de puissance à des contacts de puissance fixes, séparables de contacts mobiles portés par le porte-contacts, et situées dans un plan de câblage principal. Les bornes de commande sont reliées à des bornes de la bobine de l'électroaimant et sont situées dans un plan de câblage de commande.It should be remembered that the power terminals of the body are connected by power conducting parts to fixed, separable power contacts movable contacts carried by the contact carrier, and located in a wiring plan main. The control terminals are connected to terminals of the coil of the electromagnet and are located in a control wiring plan.

On sait que, selon la configuration souhaitée, l'électroaimant du contacteur peut être disposé à l'avant ou à l'arrière du corps. Il est utile de préciser que le terme "avant" désigne le côté du corps par lequel on accède avec un outil aux bornes de puissance, le plan de câblage principal étant donc à l'avant du corps, et que le terme "arrière" désigne le côté du corps doté des éléments de fixation.It is known that, depending on the desired configuration, the electromagnet of the contactor can be placed in front of or behind the body. It is useful to specify that the term "before" means the side of the body through which a tool is accessed through power, the main wiring plan being at the front of the body, and the "back" refers to the side of the body with the fasteners.

Dans certains contacteurs actuels où la bobine de l'électroaimant est logée à l'arrière du corps, le plan de câblage de commande est également disposé, en conséquence et de manière logique, à l'arrière du boítier d'arc qui constitue l'essentiel du corps et forme en même temps un socle de fixation du contacteur par vissage ou encliquetage sur un support tel qu'un profilé ou une platine. Un additif de contrôle peut être rajouté à l'avant du corps, les bornes de cet additif définissant un plan de câblage de contrôle disposé à l'avant du plan de câblage principal.In some current contactors where the coil of the electromagnet is housed at the back of the body, the control wiring plan is also arranged, accordingly and logically, at the back of the arc housing which is essential the body and at the same time forms a base for fixing the contactor by screwing or snap on a support such as a profile or a plate. A control additive can be added to the front of the body, the boundaries of this additive defining a control wiring plan located at the front of the main wiring plan.

Le câblage de commande est différencié du câblage de puissance, mais son implantation ne peut pas être modifiée sans entraíner de changement du boítier d'arc. De plus, il est désavantageux que l'adjonction de bornes de puissance de types différents à ces contacteurs ne puisse s'opérer qu'à la condition de prévoir autant de corps différents.The control wiring is differentiated from the power wiring, but its implementation can not be changed without changing the arc housing. Moreover, it is disadvantageous that the addition of power terminals of types different to these contactors can only operate on the condition of providing as much of different bodies.

Dans d'autres contacteurs actuels à bobine arrière, le plan de câblage de commande est confondu avec le plan de câblage principal. Le cloisonnement nécessaire d'une part entre les diverses bornes de puissance et d'autre part entre les bornes de commande et les bornes de puissance voisines est assuré par des cloisons prévues sur le boítier d'arc.In other current coil contactors, the control wiring plan is confused with the main wiring plan. The necessary partitioning on the one hand between the various power terminals and on the other hand between control terminals and adjacent power terminals is provided by bulkheads provided on the arc housing.

Il en résulte que les câblages de puissance et de commande ne sont pas suffisamment différenciés et que, si l'on souhaite disposer d'une connectique de puissance à bornes élastiques plutôt qu'à bornes à vis, il faut là aussi prévoir des corps de contacteur différents.As a result, the power and control wiring are not sufficiently differentiated and that, if one wishes to have a power connection with elastic terminals rather than with screw terminals, it is also necessary to provide different contactor.

La présente invention a pour but de faciliter, dans un contacteur à implantation de bobine arrière, la différenciation entre le câblage de puissance d'une part, le câblage de commande et le cas échéant de contrôle d'autre part.The present invention aims to facilitate, in a contactor with implantation of rear coil, the differentiation between the power wiring on the one hand, the wiring of control and if necessary of control on the other hand.

Elle a pour autre but de simplifier la réalisation d'une gamme de contacteurs à bobine arrière aptes à être dotés de bornes de connexion de puissance de types différents.Its other purpose is to simplify the production of a range of coil contactors rear terminals to be equipped with power connection terminals of different types.

Selon l'invention, l'électroaimant est disposé à l'arrière du corps et le plan de câblage de commande est disposé à l'avant du plan de câblage de puissance. De préférence, les bornes de commande sont disposées dans un bornier de commande situé à l'avant du corps du contacteur.According to the invention, the electromagnet is disposed at the rear of the body and the wiring plan The control panel is disposed at the front of the power wiring plane. Of preferably, the control terminals are arranged in a control terminal block located at the front of the contactor body.

Des conducteurs de liaison raccordant des bornes de la bobine, logée dans une partie arrière du corps, aux bornes de commande, logées dans une partie avant du corps, s'étendent perpendiculairement aux plans de câblage de commande et de puissance. Les conducteurs de liaison s'étendent avantageusement dans des espaces tels que des rainures, ménagés entre une face interne du corps du contacteur et une face externe d'un boítier d'arc qui contient le porte-contacts mobile et qui est disposé à l'intérieur du corps.Connecting conductors connecting terminals of the coil, housed in a rear part of the body, to the control terminals, housed in a front part of the body, extend perpendicular to control wiring planes and power. The connecting conductors advantageously extend into spaces such as grooves formed between an internal face of the body of the contactor and an outer face of an arc housing which contains the movable contact carrier and which is arranged inside the body.

Quand il est prévu des contacts de contrôle, le corps du contacteur peut loger des contacts fixes de contrôle et présenter des bornes de contrôle reliées à ces contacts fixes, les bornes de contrôle étant situées dans un plan de câblage confondu avec le plan de câblage de commande. Les bornes de contrôle sont de préférence logées avec les bornes de commande dans un bornier commun de commande/contrôle situé à l'avant du corps du contacteur et assemblé à celui-ci. When control contacts are provided, the body of the contactor can house fixed control contacts and present control terminals connected to these contacts the control terminals being located in a combined wiring plan with the control wiring plan. Control terminals are preferably housed with the control terminals in a common control / control terminal block located at the front of the body of the contactor and assembled to it.

Le corps du contacteur peut comprendre à l'arrière un socle qui permet la fixation à un support et le logement des éléments fixes de l'électroaimant et à l'avant un bornier de puissance qui loge les bornes de puissance, le socle et le bornier de puissance formant une enveloppe externe coiffant un boítier d'arc qui abrite le porte-contacts mobile.The body of the contactor can include at the back a base that allows the attachment to a support and the housing of the fixed elements of the electromagnet and at the front a terminal block of power that houses the power terminals, the base and the terminal block forming an outer casing covering an arc housing which houses the contact carrier mobile.

    • Le contacteur électromécanique multipolaire représenté comporte un corps, c'est-à-dire une enveloppe externe, 10 présentant une partie avant 10a et une partie arrière 10b. La partie avant 10a loge des bornes de puissance A, des bornes de commande B et des bornes de contrôle C. La partie arrière 10b est dotée d'éléments usuels 11 de fixation à un support et loge l'essentiel d'un électroaimant 20. Le corps 10 inclut des lignes de courant de puissance 12 à double coupure ; ces lignes 12 présentent des pièces conductrices fixes 13 portant des contacts de puissance fixes 14, ainsi que des contacts de puissance mobiles 15 situés sur des ponts de contact 16. Les ponts mobiles de contact 16 sont logés dans un porte-contacts 17 déplaçable en fonction de la sollicitation de la bobine 21 de l'électroaimant 20. The multipolar electromechanical contactor shown comprises a body, that is to say an outer casing 10 having a front portion 10a and a rear portion 10b. The front portion 10a houses power terminals A, control terminals B and control terminals C. The rear portion 10b is provided with elements used to attach to a support and houses the essential of an electromagnet 20. The body 10 includes double cut power power lines 12; these lines 12 have fixed conductive parts 13 carrying fixed power contacts 14, as well as movable power contacts 15 located on contact bridges 16. The movable movable bridges 16 are housed in a displaceable contact holder 17 depending on the solicitation of the coil 21 of the electromagnet 20.

    Dans la partie avant 10a du corps 10, les bornes de puissance A sont situées dans un plan de câblage principal PA pour assurer l'insertion de câbles conduisant à une source d'alimentation et à une charge, pour mettre sous tension les lignes de courant 13 ; de plus, dans la partie avant 10a sont situées des bornes de commande B définissant un plan de câblage de commande PB situé à l'avant du plan PA, pour l'insertion de câbles reliés à un circuit de commande, ces bornes étant reliées à l'intérieur du contacteur à la bobine 21 de l'électroaimant 20. Dans la partie avant 10a sont enfin situées des bornes de contrôle C définissant un plan de câblage PC situé à l'avant du plan PA et par exemple confondu avec le plan PB, ces bornes étant reliées par des câbles ou un bus à un circuit de contrôle, signalisation, ou analogue.In the front portion 10a of the body 10, the power terminals A are located in a PA main wiring plan to ensure the insertion of cables leading to a power source and at a load, to power up the power lines 13; moreover, in the front part 10a there are control terminals B defining a control wiring plane PB located at the front of the plane PA, for insertion of cables connected to a control circuit, these terminals being connected to the inside of the contactor to the coil 21 of the electromagnet 20. In the front part 10a are finally located control terminals C defining a PC wiring plan located at the front of the plane PA and for example confused with the plane PB, these terminals being connected by cables or a bus to a control circuit, signaling, or similar.

    Plus en détail, le corps ou boítier 10 du contacteur comprend un socle 30 en matière isolante à forme générale de cuvette parallélépipédique ; ce socle constitue l'essentiel de la partie arrière précitée 10b et il est donc doté des éléments de fixation 11 et loge la bobine 21 de l'électroaimant 20, ainsi que l'armature fixe 22 en E avec l'âme du E disposée verticalement.In more detail, the body or housing 10 of the contactor comprises a base 30 made of insulation with a general shape of parallelepipedic bowl; this base constitutes the bulk of the aforementioned rear part 10b and it is therefore provided with the fastening elements 11 and houses the coil 21 of the electromagnet 20, as well as the fixed armature 22 in E with the soul of the E arranged vertically.

    Dans le corps 10 est situé un boítier d'arc 40 en matière isolante appropriée logeant une partie de l'armature mobile 23 en E de l'électroaimant 20 et le porte-contacts 17. Le porte-contacts 17 (voir figures 4, 5 et 7) loge les ponts de contact 16 portant chacun les deux contacts mobiles 15 du pôle respectif. En regard des contacts mobiles sont situés des contacts fixes 14 respectifs, reliés par les pièces conductrices 13 aux bornes de puissance A, les pièces 13 étant à cet effet munies de plages de fixation taraudées 13a. Le porte-contacts 17 comprend une partie arrière 17a logeant les ponts de puissance 16 et une partie avant 17b logeant des contacts mobiles de contrôle 18 destinés à coopérer avec des contacts fixes de contrôle 19 comme on le verra plus loin.

The coil 21 has an insulating casing 24 carrying the coil 25 and provided with two coil terminals 26 to be connected to the control terminals B. The said connection is effected by means of respective conductive strips 27 oriented substantially perpendicular to the front face of the contactor, these strips being housed in transverse grooves 28 provided on the outside of the housing of arc 40.

    Le boítier d'arc 40 a une forme étagée, à savoir un étage définissant le plan de câblage PA, consacré à la liaison contacts de puissance - bornes de puissance et coiffé par un bornier de puissance 50, et un étage définissant le plan de câblage PB,PC, consacré à la liaison contacts de contrôle/commande -bornes de contrôle/commande et coiffé par un bornier de contrôle/commande 60. Le boítier d'arc 40 est constitué par assemblage de deux demi-boítiers 40a,40b selon un plan horizontal qui peut être le plan médian Q du contacteur ou un plan parallèle à Q. Chaque demi-boítier 40a,40b comprend des cloisons internes 41 destinées à assurer un isolement convenable entre les contacts de puissance des divers pôles, mais est par contre dépourvu de cloisons externes d'isolement entre les bornes de puissance ; chaque demi-boítier comporte des guidages et rainures 42 permettant de mettre en place et positionner des cloisons d'isolement inter-bornes 51 prévues dans le bornier de puissance 50. A l'avant du boítier d'arc 40 sont prévus des éléments de forme 44 permettant l'accrochage d'un additif frontal au contacteur.The arc housing 40 has a stepped shape, namely a floor defining the wiring plane PA, dedicated to the connection of power contacts - power terminals and capped by a power terminal block 50, and a stage defining the wiring plan PB, PC, dedicated to the connection of control / command contacts - control / control terminals and capped by a control terminal / control 60. The arc housing 40 is constituted by assembling two half-housings 40a, 40b in a horizontal plane which can be the median plane Q of the contactor or a plane parallel to Q. Each half-housing 40a, 40b includes internal partitions 41 to ensure proper isolation between the power contacts of the various poles but is However, there are no external isolation walls between the power terminals ; each half-housing comprises guides and grooves 42 making it possible to set up and position inter-terminal isolating partitions 51 in the power terminal block 50. At the front of the arc housing 40 are provided elements form 44 for attachment of a front additive to the contactor.

    Comme on le voit figure 3, et accessoirement figures 6,7, chaque cloison 51 présente une partie arrière 51 a qui pénètre dans une rainure 42a correspondante située derrière les plages de fixation 13 adjacentes ; la cloison 51 offre aussi une partie en retrait 51 b qui pénètre dans une rainure 42b correspondante située au niveau de la pièce active (vis-étrier, cage élastique,..) de la borne de puissance A. La partie de la cloison située vers le plan médian Q du contacteur comprend deux glissières 51c qui coopèrent avec des rainures horizontales 42c (voir aussi figures 9,10). On constate que les rainures 42a,42b,42c déterminent, avec les éléments associés des cloisons 51, des chicanes augmentant la distance d'isolement entre pièces conductrices de puissance. Le bornier de puissance présente une paroi 52 de plan Q' parallèle au plan médian Q du contacteur et servant de plan de base pour la borne.As seen in Figure 3, and incidentally Figures 6,7, each partition 51 presents a rear portion 51a which penetrates into a corresponding groove 42a located behind the adjacent attachment pads 13; the partition 51 also offers a recessed portion 51b that enters a corresponding groove 42b located at level of the active part (screw-stirrup, elastic cage, ..) of the power terminal A. The part of the bulkhead located towards the median plane Q of the contactor comprises two slides 51c which cooperate with horizontal grooves 42c (see also figures 9,10). It is found that the grooves 42a, 42b, 42c determine, with the elements associated partitions 51, baffles increasing the isolation distance between power conducting parts. The power terminal block has a wall 52 plane Q 'parallel to the median plane Q of the contactor and serving as a basic plane for the terminal.

    Il convient d'observer que le bornier de puissance 50 peut être adapté à des types de connectique différents sans que le boítier d'arc ne doive être modifié. Il est indiqué à titre d'exemple sur les figures 9 et 10 l'adjonction au boítier d'arc d'un bornier 50-1 à bornes élastiques A1 et respectivement d'un bornier 50-2 à bornes à vis A2. Comme on le voit sur les figures 3, 9 et 10, l'espace 53 dévolu à la partie active ou déplaçable de la borne A entre la paroi 52 et la paroi extérieure adjacente 54 de plan Q" du bornier a un volume variable en hauteur (direction Y) et en profondeur (direction X) alors que le boítier d'arc reste identique. Le bornier présente des ouvertures frontales 55 permettant l'accès d'un outil de manoeuvre des bornes et des ouvertures supérieures ou inférieures 56 situées dans le plan de câblage PA et servant à l'introduction de câbles de puissance, les ouvertures 55,56 débouchant dans l'espace 53. Un espace de décompression 57 est formé entre la paroi 52 du bornier et une paroi parallèle 43, dotée de trous d'évent, du boítier d'arc. Le bornier 50 offre à l'avant une fenêtre 58 traversée par la partie avant du boítier d'arc 40.It should be noted that the power terminal block 50 can be adapted to types different connectors without the arc housing should be changed. It is indicated by way of example in FIGS. 9 and 10, the addition to the arc box of a terminal block 50-1 with elastic terminals A1 and respectively with a terminal block 50-2 with screw terminals A2. As can be seen in FIGS. 3, 9 and 10, the space 53 devolved to the active part or movable from the terminal A between the wall 52 and the adjacent outer wall 54 of plane Q "of the terminal block has a variable volume in height (Y direction) and in depth (X direction) while the arc housing remains the same. The terminal block has openings 55 allowing access to a terminal operating tool and upper or lower openings 56 located in the PA wiring plane and serving to the introduction of power cables, the openings 55,56 opening into space 53. A decompression space 57 is formed between the wall 52 of the terminal block and a parallel wall 43, provided with vent holes, the arc housing. Terminal block 50 offers at the front a window 58 crossed by the front portion of the arc housing 40.

    Un bornier de commande/contrôle 60 est assemblé à l'avant du corps de contacteur, ce bornier présentant des ouvertures frontales 61 permettant l'accès d'un outil de manoeuvre des bornes et des ouvertures supérieures ou inférieures 62 situées dans le plan de câblage PB,PC et servant à l'introduction de câbles de commande et de contrôle. Le bornier 60 a un gabarit qui permet de l'encastrer dans la fenêtre 58 du bornier de puissance 50 et il est doté d'une ouverture frontale 63 de passage pour la partie avant du boítier d'arc 40.A control / control terminal block 60 is assembled at the front of the contactor body, this terminal block having front openings 61 allowing access to a tool operating the terminals and upper or lower openings 62 located in the wiring diagram PB, PC and used for the introduction of control cables and control. The terminal block 60 has a template that allows it to be embedded in the window 58 of the power terminal block 50 and has a front opening 63 passage for the front part of the arc housing 40.

    Il convient de remarquer que le corps du contacteur est constitué par l'assemblage du bornier de puissance et du socle, de sorte que ces deux éléments forment la paraison externe du contacteur et enveloppent complètement le boítier d'arc. Le bornier de puissance 50 est fixé par tous moyens usuels au socle 30 et le bornier de commande/contrôle 60 est fixé par tous moyens usuels au bornier 50 et/ou au boítier d'arc 40.It should be noted that the body of the contactor is constituted by the assembly of the power terminal block and the base, so that these two elements form the external parison of the contactor and completely envelop the housing arc.
