Description

La présente invention concerne de manière générale les connecteurs électriques pour appareillage électrique à rapporter dans une goulotte de cheminement de conducteurs électriques, tel qu'une prise de courants forts ou faibles, un interrupteur, une prise de télévision, un porte-fusible et un voyant lumineux.The present invention generally relates to electrical connectors for electrical equipment to report in a trunking of electrical conductors, such as a strong or weak currents, a switch, a TV socket, a fuse holder and a light luminous.

Elle concerne plus particulièrement un connecteur électrique pour un appareillage électrique comprenant une partie avant fonctionnelle et une partie arrière logeant des lames métalliques de connexion électrique.It relates more particularly to an electrical connector for an electrical equipment comprising a functional front portion and a rear portion housing metal connection blades.

Un tel appareillage électrique peut constituer avantageusement un appareillage modulaire pouvant être associé à un autre appareillage électrique complémentaire de façon à constituer une réglette d'appareillages électriques.Such electrical equipment may advantageously be a modular apparatus that can be associated with another complementary electrical apparatus so as to constitute a strip of electrical equipment.

La présente invention concerne également un système électrique comprenant, d'une part, un appareillage électrique à rapporter dans une goulotte, et, d'autre part, un tel connecteur électrique.The present invention also relates to an electrical system comprising, on the one hand, an electrical equipment to report in a chute, and, on the other hand, such an electrical connector.

On connaît déjà du document FR 2 727 801 un appareillage électrique modulaire qui comprend, pour son alimentation en courant électrique, un bornier apte à être positionné sur une face d'extrémité dudit appareillage électrique.Already known from FR 2,727,801 is a modular electrical apparatus which comprises, for its power supply, a terminal block adapted to be positioned on an end face of said electrical equipment.

Ce bornier comporte une face avant supérieure fermée afin d'interdire tout accès à l'intérieur du bornier lorsque celui-ci est installé, et une face arrière inférieure fermée.This terminal has a closed upper front face to prevent access to the inside of the terminal block when it is installed, and a lower rear face closed.

Il comporte en outre un support de contact comprenant, à une extrémité, des moyens de fixation des conducteurs électriques à raccorder à l'appareillage électrique. Ces moyens de fixation sont par exemple des plots à vis.It further comprises a contact support comprising, at one end, means for fixing the electrical conductors to be connected to the electrical equipment. These fixing means are for example screw pads.

Ces plots à vis sont solidarisés à des lames conductrices placées à l'extrémité opposée du support de contact du bornier. Ces lames conductrices sont destinées à venir au contact des extrémités des lames métalliques de connexion électrique de l'appareillage électrique, lorsque le bornier est accouplé à ce dernier par une de ses faces d'extrémité.These screw pads are secured to conductive blades placed at the opposite end of the contact support of the terminal block. These conductive blades are intended to come into contact with the ends of the metal blades for electrical connection of the electrical equipment, when the terminal block is coupled to the latter by one of its end faces.

Outre le fait que le connecteur électrique précité est relativement complexe, il est positionné dans la goulotte au même niveau que l'appareillage électrique auquel il est raccordé dans l'alignement de celui-ci. Il est donc nécessaire de prévoir, dans un tel connecteur électrique, des aménagements pour interdire l'accès à ses moyens de connexion électrique. En outre, il prend une certaine place dans la goulotte, place qui devient non disponible pour la mise en place d'un autre appareillage électrique dans celle-ci.In addition to the fact that the aforementioned electrical connector is relatively complex, it is positioned in the chute at the same level as the electrical equipment to which it is connected in alignment thereof. It is therefore necessary to provide, in such an electrical connector, arrangements to prohibit access to its electrical connection means. In addition, he takes a certain place in the chute, a place that becomes unavailable for the installation of another electrical equipment in it.

On connaît également du document FR 2 691 846 un appareillage électrique comprenant une partie avant adaptée à recevoir une fiche de raccordement électrique et une partie arrière dotée de pièces de contact femelles adaptées à recevoir les broches de ladite fiche et à se connecter à un câble du réseau d'alimentation électrique.Document FR 2 691 846 also discloses an electrical apparatus comprising a front part adapted to receive an electrical connection plug and a rear part provided with female contact pieces adapted to receive the pins of said plug and to connect to a cable of the power supply network.

Selon ce document, la partie arrière de cet appareillage électrique comporte des contacts métalliques autodénudants en nombre égal au nombre de conducteurs du réseau d'alimentation électrique, pour connecter ledit appareillage électrique au réseau d'alimentation électrique.According to this document, the rear part of this electrical equipment comprises insulation displacement metal contacts in a number equal to the number of conductors of the power supply network, for connecting said electrical equipment to the power supply network.

Cet appareillage électrique comporte également un cache en matériau isolant pouvant s'emboîter sur sa partie arrière, ce cache comportant des guides disposés en correspondance avec les contacts métalliques autodénudants de la partie arrière du corps de l'appareillage électrique et adaptés à recevoir les conducteurs électriques du réseau d'alimentation électrique pour les positionner en face des fentes desdits contacts métalliques autodénudants et les faire pénétrer dans lesdites fentes lors de l'emboîtement dudit cache sur la partie arrière du corps de l'appareillage électrique.This electrical apparatus also comprises a cover of insulating material which can be fitted on its rear part, this cover comprising guides arranged in correspondence with the metal insulation displacement contacts of the rear part of the body of the electrical equipment and adapted to receive the electrical conductors. the power supply network to position them in front of the slots of said insulation displacement metal contacts and make them penetrate into said slots during the nesting of said cover on the rear part of the body of the electrical equipment.

Un tel système d'appareillage électrique et de connecteur électrique est relativement complexe et difficile à mettre en oeuvre dans une goulotte, sans l'intervention d'une pince spéciale pour aider à la mise en place du cache sur la partie arrière de l'appareillage électrique, afin d'insérer lesdits conducteurs que le cache porte dans les fentes des contacts métalliques autodénudants dudit appareillage électrique.Such a system of electrical equipment and electrical connector is relatively complex and difficult to implement in a chute, without the intervention of a special clamp to help the establishment of the cover on the rear part of the apparatus electrical, so as to insert said conductors that the cover carries in the slots of the insulation displacement metal contacts of said electrical equipment.

Enfin, on connaît un connecteur électrique du type "vampire" pour appareillage électrique à bornes à vis, qui comprend un boîtier isolant logeant une lame de connexion comportant, d'un côté du boîtier, une paire de contacts métalliques autodénudants pour le raccordement à un conducteur électrique circulant dans une goulotte, et, de l'autre côté du boîtier, des contacts métalliques pour le branchement d'une cosse reliée à un fil électrique connecté à une des bornes dudit appareillage électrique.Finally, there is known a "vampire" type electrical connector for electrical equipment with screw terminals, which comprises an insulating housing housing a connecting blade comprising, on one side of the housing, a pair of insulation displacement metal contacts for connection to a terminal. electrical conductor circulating in a chute, and on the other side of the housing, metal contacts for the connection of a terminal connected to an electrical wire connected to one of the terminals of said electrical equipment.

L'inconvénient principal d'un tel connecteur électrique est qu'il nécessite un précâblage de l'appareillage électrique avec le fil électrique muni de la cosse de branchement audit connecteur.The main disadvantage of such an electrical connector is that it requires a prewiring of the electrical equipment with the electrical wire provided with the connection lug to said connector.

Par rapport à l'état de la technique précité, la présente invention propose un nouveau connecteur électrique pour un appareillage électrique comprenant une partie avant fonctionnelle et une partie arrière logeant des lames métalliques de connexion électrique, qui est simple à mettre en oeuvre dans la goulotte pour raccorder électriquement l'appareillage électrique en question au réseau d'alimentation électrique.Compared to the prior art, the present invention proposes a new electrical connector for electrical equipment comprising a functional front portion and a rear portion housing metal connection blades, which is simple to implement in the chute for electrically connecting the electrical equipment in question to the power supply network.

Plus particulièrement, la présente invention propose un connecteur électrique du type de celui défini en introduction, caractérisé en ce qu'il comprend un boîtier isolant logeant au moins une lame de connexion comportant, d'un côté du boîtier, une paire de contacts métalliques autodénudants pour le raccordement d'un conducteur électrique circulant dans ladite goulotte, et, de l'autre côté du boîtier, au moins un contact métallique destiné à être inséré dans la partie arrière de l'appareillage électrique, via un orifice prévu dans sa paroi de fond, pour venir en prise avec une des lames métalliques de connexion électrique dudit appareillage électrique.More particularly, the present invention provides an electrical connector of the type defined in the introduction, characterized in that it comprises an insulating housing housing at least one connecting blade having, on one side of the housing, a pair of self-cutting metal contacts for the connection of an electrical conductor flowing in said chute, and, on the other side of the housing, at least one metal contact to be inserted in the rear part of the electrical equipment, via an orifice provided in its wall of bottom, to engage with one of the metal blades of electrical connection of said electrical equipment.

Ainsi, selon l'invention, le connecteur électrique est avantageusement positionné sur la face arrière de l'appareillage électrique à rapporter sur le socle d'une goulotte, il devient donc difficilement accessible lorsqu'il est mis en place sur l'appareillage électrique placé dans la goulotte et prend aucune place supplémentaire dans le sens longitudinal de ladite goulotte, place pouvant être réservée à la mise en place d'un autre appareillage électrique du même type.Thus, according to the invention, the electrical connector is advantageously positioned on the rear face of the electrical equipment to be reported on the base of a chute, so it becomes difficult to access when it is put in place on the electrical equipment placed in the chute and takes no additional place in the longitudinal direction of said chute, place that can be reserved for the establishment of another electrical equipment of the same type.

En outre, le connecteur électrique, selon l'invention, comportant les contacts métalliques autodénudants, est facilement mis en place sur des conducteurs électriques circulant déjà dans la goulotte et permet alors de réaliser un repiquage sur un réseau électrique existant.In addition, the electrical connector according to the invention, comprising the insulation displacement metal contacts, is easily put in place on electrical conductors already circulating in the chute and then makes it possible to perform a subculture on an existing electrical network.

La prise directe de chaque lame de connexion du connecteur électrique conforme à l'invention, sur chaque lame métalliques de connexion électrique de l'appareillage électrique, évite un précâblage de ce dernier.The direct connection of each connecting blade of the electrical connector according to the invention, on each metal blade electrical connection of the electrical equipment, avoids a prewiring of the latter.

Selon une caractéristique avantageuse du connecteur électrique selon l'invention, chaque lame de connexion est agencée de sorte que la paire de contacts métalliques autodénudants et ledit contact métallique s'étendent selon la même direction dans des sens opposés.According to an advantageous characteristic of the electrical connector according to the invention, each connecting blade is arranged so that the pair of insulation displacement metal contacts and said metal contact extend in the same direction in opposite directions.
