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 fixing elements to a support and houses an electromagnet and a movable contact carrier, the electromagnet comprising a coil, a fixed armature and a movable armature capable of displacing the contact carrier, the body including 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 recalled that the power terminals of the body are connected by power conducting parts to fixed power contacts, separable from movable contacts carried by the contact carrier, and located in a main wiring plane. The control terminals are connected to terminals of the solenoid coil and are located in a control wiring plane.

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 arranged at the front or rear of the body. It is useful to specify that the term "front" refers to the side of the body through which a tool is accessed at the power terminals, the main wiring plan being at the front of the body, and the term "rear" means the side of the body with 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 boîtier 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 solenoid coil is housed at the rear of the body, the control wiring plane is also logically and logically arranged at the rear of the arc case which constitutes the essential 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 may be added to the front of the body, the terminals of this additive defining a control wiring plane disposed in front of the main wiring plane.

Le câblage de commande est différencié du câblage de puissance, mais son implantation ne peut pas être modifiée sans entraîner de changement du boîtier 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 enclosure. In addition, it is disadvantageous that the addition of power terminals of different types to these contactors can be operated only provided to provide as many 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 boîtier d'arc.In other current coil contactors, the control wiring plan is merged with the main wiring plan. The partitioning necessary on the one hand between the various power terminals and on the other hand between the control terminals and the adjacent power terminals is provided by partitions 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 if it is desired to have a power connection with elastic terminals rather than 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 de contrôle d'autre part.The purpose of the present invention is to facilitate, in a rear coil layout contactor, the differentiation between the power wiring on the one hand and the control and control wiring 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 rear coil contactors adapted 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 et de contrôle est disposé à l'avant du plan de câblage de puissance. 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 control and control wiring plane is disposed at the front of the power wiring plane. The control terminals are located 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 boîtier 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 perpendicularly to the control and power wiring planes. The connecting conductors advantageously extend in spaces such as grooves, formed between an inner 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 at the inside the body.

Quand il est prévu des contacts de contrôle, le corps du contacteur loge des contacts fixes de contrôle et présente 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 contactor body houses fixed control contacts and has control terminals connected to these fixed contacts, the control terminals being located in a wiring plane coinciding with the control wiring plan. . The control terminals are preferably housed with the control terminals in a common control / control terminal block located at the front of the contactor body 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 boîtier d'arc qui abrite le porte-contacts mobile.The body of the contactor can comprise at the rear a base which allows the attachment to a support and the housing of the fixed elements of the electromagnet and at the front a power terminal block which houses the power terminals, the base and the terminal block an outer casing forming an arc housing which houses the movable contact carrier.

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 multipole electromechanical contactor shown has a body, i.e., an outer casing, 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 usual elements 11 for attachment to a support and houses the bulk 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.

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 main wiring plane PA to insure the insertion of cables leading to a power source and a load, to power the power lines. 13; furthermore, in the front part 10a there are control terminals B defining a control wiring plane PB situated in front of the plane PA, for the insertion of cables connected to a control circuit, these terminals being connected to the inside of the contactor coil 21 of the electromagnet 20.

Plus en détail, le corps ou boîtier 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 of insulating material generally parallelepiped shaped bowl; this base constitutes the bulk of the aforementioned rear part 10b and is therefore provided with the fixing 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 boîtier 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.
