Description

CONNECTEUR ELECTRIQUE POUR DES CABLES ELECTRICAL CONNECTOR FOR CABLES
L'invention se rapporte à un connecteur électrique.The invention relates to an electrical connector.
Pour réaliser une connexion électrique entre deux extrémités de câble conducteur, il était classique de réaliser une épissure par entrelacement ou torsade des deux torons de câble conducteurs.To make an electrical connection between two ends of conductive cable, it was conventional to make a splicing by interlacing or twisting of the two strands of conductive cable.
Ensuite, il était nécessaire de recouvrir la partie torsadée et dénudée d'un revêtement isolant.Then it was necessary to cover the twisted and stripped part with an insulating coating.
Pour ce faire, on utilisait une bande souple en matériau isolant électriquement revêtue sur l'une de ses deux faces d'un adhésif. Cette solution longtemps utilisée n'est plus conforme aux normes de sécurité et il existe donc différentes méthodes.To do this, we used a flexible strip of electrically insulating material coated on one of its two faces with an adhesive. This solution, which has been used for a long time, no longer complies with security standards and there are therefore different methods.
Une première méthode consiste à remplacer la bande adhésive par une gaine thermo-rétractable.A first method consists in replacing the adhesive strip by a heat-shrinkable sheath.
Un tel dispositif n'offre malheureusement pas une sécurité suffisante notamment sur l'aspect de la résistance mécanique de la gaine.Unfortunately, such a device does not offer sufficient security, particularly with regard to the aspect of the mechanical strength of the sheath.
On connaît d'autres dispositifs qui consistent à prévoir, dans un boîtier isolant rigide, un logement contenant localement une pièce métallique conductrice qui s'étend sensiblement sur une distance équivalente à la longueur cumulée des extrémités dénudées des câbles conducteurs. On met en contact une extrémité dénudée du câble conducteur sur une extrémité de la pièce conductrice et on procède de la même façon avec l'autre conducteur de sorte que c'est la pièce conductrice qui assure la continuité électrique entre les deux câbles.Other devices are known which consist in providing, in a rigid insulating housing, a housing locally containing a conductive metal part which extends substantially over a distance equivalent to the cumulative length of the stripped ends of the conductive cables. A stripped end of the conductive cable is brought into contact with one end of the conductive part and the same procedure is carried out with the other conductor so that it is the conductive part which provides electrical continuity between the two cables.
Parfois, cette pièce conductrice se présente sous la forme d'un manchon déformable plastiquement pour permettre un sertissage ou sous la forme d'une vis.Sometimes this conductive part is in the form of a plastically deformable sleeve to allow crimping or in the form of a screw.
Différents problèmes se posent.Different problems arise.
En premier lieu, le matériau constituant la pièce conductrice est généralement un matériau différent de celui constituant le conducteur de sorte que cela génère des phénomènes qui, au cours du temps, nuisent au bon contact électrique.First, the material constituting the conductive part is generally a different material from that constituting the conductor so that this generates phenomena which, over time, affect good electrical contact.
Un autre problème résulte du fait également que la pièce conductrice ne permet pas de vérifier visuellement s'il existe effectivement un contact. On connaît un dispositif de connexion DE 197 40 456 construit pour une douille céramique conique dans laquelle on y positionne les âmes de deux connecteurs. Une des âmes est pourvue d'un alésage dans lequel pénètre l'autre âme. La forme conique assure un serrage. Sur cette douille conique, est prévue ensuite une protection isolante. Un tel assemblage n'est pas destiné au grand public et n'est valable que pour certains conducteurs.Another problem also results from the fact that the conductive part does not make it possible to visually check whether there is actually a contact. There is known a connection device DE 197 40 456 constructed for a conical ceramic socket in which the cores of two connectors are positioned there. One of the souls has a bore into which the other soul enters. The conical shape ensures tightening. An insulating protection is then provided on this conical sleeve. Such an assembly is not intended for the general public and is only valid for certain drivers.
L'invention se propose de notamment remédier aux inconvénients précitésThe invention proposes in particular to remedy the aforementioned drawbacks
A cet effet, l'invention a pour objet un connecteur électrique pour relier électriquement deux âmes conductrices de section prédéterminée d'un câble, comprenant un boîtier isolant rigide présentant un logement débouchant au moins indirectement dans deux faces opposées du boîtier, ce connecteur étant caractérisé en ce que le logement comprend :To this end, the subject of the invention is an electrical connector for electrically connecting two conductive cores of predetermined section of a cable, comprising a rigid insulating housing having a housing opening at least indirectly into two opposite faces of the housing, this connector being characterized in that the accommodation includes:
- une chambre médiane de dimension longitudinale et de section prédéterminées pour contenir côte à côte les âmes conductrices, - un moyen élastique qui, serrant les deux âmes conductrices l'une contre l'autre, est en matériau isolant électriquement,- a central chamber of longitudinal dimension and of predetermined section to contain the conductive cores side by side, - an elastic means which, clamping the two conductive cores against each other, is made of electrically insulating material,
- de part et d'autre de cette chambre médiane et débouchant dans cette dernière par un canal de section au moins égale à la section de l'âme conductrice qui le traverse, une chambre dite de verrouillage comprenant des moyens de verrouillage en translation du câble.- on either side of this median chamber and opening into the latter by a channel of section at least equal to the section of the conductive core which passes through it, a so-called locking chamber comprising means for locking in translation of the cable .
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents:
- figure 1 : le connecteur ouvert vu en perspective, - figures 2 et 3 : le connecteur vu en coupe,- Figure 1: the open connector seen in perspective, - Figures 2 and 3: the connector seen in section,
- figure 4 : une variante du connecteur en coupe,- Figure 4: a variant of the connector in section,
- figure 5 : une vue en perspective d'une partie de la variante de la figure 4.- Figure 5: a perspective view of part of the variant of Figure 4.
En se reportant au dessin, on voit un connecteur 1 électrique. Par connecteur 1 électrique, on comprendra une pièce destinée à relier électriquement deux âmes 2 conductrices d'un câble électrique en vue d'assurer la continuité électrique entre les deux câbles. Le câble électrique comprend une âme 2 conductrice recouverte d'une gaine 3 isolante assurant la protection électrique.Referring to the drawing, we see an electrical connector 1. By electrical connector 1 is understood a part intended to electrically connect two conductive cores 2 of an electrical cable in order to ensure electrical continuity between the two cables. The electric cable comprises a conductive core 2 covered with an insulating sheath 3 providing electrical protection.
Classiquement, le connecteur 1 comprend un boîtier 4 isolant rigide présentant un logement débouchant au moins indirectement dans deux faces 5, 6 opposées du boîtier.Conventionally, the connector 1 comprises a rigid insulating housing 4 having a housing opening at least indirectly into two opposite faces 5, 6 of the housing.
Ces faces opposées présentent donc des lumières 7, 8 permettant le passage des câbles pour le raccordement électrique des extrémités dénudées desdits câbles.These opposite faces therefore have openings 7, 8 allowing the passage of the cables for the electrical connection of the stripped ends of said cables.
Selon une caractéristique le logement comprend : - une chambre 9 médiane de dimension longitudinale et de section prédéterminées pour contenir côte à côte les âmes 2 conductrices,According to one characteristic, the housing comprises: a median chamber 9 of longitudinal dimension and of predetermined section to contain side by side the conductive cores 2,
- un moyen 10 élastique qui, serrant les deux âmes conductrices l'une contre l'autre, est en matériau isolant électriquement,an elastic means which, pressing the two conductive cores together, is made of electrically insulating material,
- de part et d'autre de cette chambre 9 médiane et débouchant dans cette dernière par un canal 1 1 de section au moins égale à la section de l'âme conductrice qui le traverse, une chambre 12 dite de verrouillage comprenant des moyens 13 de verrouillage en translation du câble.- On either side of this median chamber 9 and opening into the latter through a channel 11 of section at least equal to the section of the conductive core which passes through it, a so-called locking chamber 12 comprising means 13 for cable translational locking.
Dans une forme de réalisation, c'est la dimension transversale de la chambre médiane par rapport à la somme des sections des âmes conductrices qui réalise le moyen 10 élastique de serrage des âmes.In one embodiment, it is the transverse dimension of the middle chamber relative to the sum of the sections of the conductive cores which provides the elastic means for clamping the cores.
La section de la chambre 9 médiane est par exemple sensiblement égale ou légèrement inférieure à la somme des sections des âmes conductrices ou somme des diamètres des âmes de sorte qu'il y a un effet de serrage. Les deux parties forment les mâchoires d'une pince. Dans une variante de réalisation, au moins localement la face interne de la chambre médiane peut être couverte d'un matériau souple qui plaque les âmes conductrices l'une contre l'autre.The section of the middle chamber 9 is for example substantially equal to or slightly less than the sum of the sections of the conductive cores or the sum of the diameters of the cores so that there is a clamping effect. The two parts form the jaws of a clamp. In an alternative embodiment, at least locally the internal face of the middle chamber can be covered with a flexible material which presses the conductive cores one against the other.
Avantageusement, le boîtier 4 présente au droit de la chambre 9 médiane une fenêtre 14 permettant de visualiser le contact entre les âmes conductrices. Cette fenêtre 14 est constituée par une simple découpe ou encore par une matière translucide ou transparente.Advantageously, the casing 4 has, to the right of the middle chamber 9, a window 14 allowing the contact between the conductive cores to be viewed. This window 14 is formed by a simple cutout or by a translucent or transparent material.
Dans une variante de réalisation, au moins une partie du boîtier qui est généralement en deux parties est transparente. Le moyen 13 de verrouillage en translation contenu dans la chambre de verrouillage comprend par exemple des pointes ou ergots répartis sur la surface interne de la chambre et qui pénètrent dans la gaine isolante recouvrant l'âme conductrice. La dimension des pointes à savoir la longueur sera de préférence déterminée pour ne pas percer en totalité la gaine isolante recouvrant l'âme conductrice.In an alternative embodiment, at least a part of the housing which is generally in two parts is transparent. The means 13 for locking in translation contained in the locking chamber comprises for example spikes or pins distributed over the internal surface of the chamber and which penetrate into the insulating sheath covering the conductive core. The dimension of the tips, namely the length, will preferably be determined so as not to completely pierce the insulating sheath covering the conductive core.
On peut également prévoir un serrage élastique ou encore un anneau serré autour de la gaine. On évitera cependant l'usage de pièces annexes.One can also provide an elastic clamping or a ring tight around the sheath. However, the use of additional parts should be avoided.
On préserve ainsi l'intégrité de l'âme conductrice et donc les risques d'oxydation.This preserves the integrity of the conductive core and therefore the risks of oxidation.
On évite par ailleurs les phénomènes liés aux vibrations ou aux différents coefficients de dilatation des matériaux métalliques utilisés auparavant qui entraînaient généralement le desserrage des vis.We also avoid the phenomena related to vibrations or to the different expansion coefficients of metallic materials used before which generally led to the loosening of the screws.
Cet anneau sera bien évidemment non métallique et donc en matériau isolant.This ring will obviously be non-metallic and therefore made of insulating material.
Ces divers éléments permettent un recyclage plus aisé.These various elements allow easier recycling.
Dans l'exemple représenté, les deux parties du boîtier sont séparables et présentent donc des moyens 15 d'assemblage. Le plan de jonction des deux parties se situe dans un plan parallèle à l'axe longitudinal.In the example shown, the two parts of the housing are separable and therefore have assembly means 15. The junction plane of the two parts lies in a plane parallel to the longitudinal axis.
Au lieu de cette solution en deux parties distinctes, on peut prévoir la présence sur l'un des cotés du connecteur d'une charnière 16 reliant les deux parties et sur l'autre coté de moyen d'assemblage, par exemple, par emboîtement.Instead of this solution in two separate parts, one can provide for the presence on one of the sides of the connector of a hinge 16 connecting the two parts and on the other side of the assembly means, for example, by interlocking.
Ces moyens d'assemblage sont :These assembly means are:
- soit démontables par exemple par déformation élastique,- either removable, for example by elastic deformation,
- soit non démontables et entraînant donc la rupture de ces moyens d'assemblage. Les dimensions transversales des chambres sont bien évidemment déterminées en fonction des caractéristiques des câbles conducteurs et notamment des sections de câbles. Le connecteur peut être adapté pour relier des câbles de sections différentes de chaque coté du connecteur.- Either not removable and therefore causing the rupture of these assembly means. The transverse dimensions of the chambers are obviously determined as a function of the characteristics of the conductive cables and in particular of the cable sections. The connector can be adapted to connect cables of different sections on each side of the connector.
Un tel connecteur peut relier deux câbles électriques disposés bout à bout mais également quatre conducteurs voire plus. On multiplie alors les chambres médianes et les chambres de verrouillage qui seront alors disposées parallèlement à l'axe longitudinal du connecteur.Such a connector can connect two electrical cables arranged end to end but also four or more conductors. The middle chambers and the locking chambers are then multiplied, which will then be arranged parallel to the longitudinal axis of the connector.
Dans une variante de réalisation, telle que le connecteur comprend au moins deux chambres médianes et donc deux connecteurs unipolaires côte à côte, les chambres médianes peuvent communiquer entre elles par un canal 1 15 dit de communication permettant de croiser les câbles ou de raccorder les deux extrémités d'un câble à deux âmes conductrices.In an alternative embodiment, such that the connector comprises at least two median chambers and therefore two unipolar connectors side by side, the median chambers can communicate with each other by a so-called communication channel 1 15 making it possible to cross the cables or to connect the two ends of a cable with two conductive cores.
Les axes des canaux 1 15 seront inclinés par exemple de 45° par rapport à l'axe longitudinal de la chambre pour faciliter la mise en place du conducteur et éviter des changements de directions trop brutaux nécessitant de plier les âmes conductrices et de générer des contraintes mécaniques néfastes.The axes of the channels 1 15 will be inclined for example by 45 ° relative to the longitudinal axis of the chamber to facilitate the positioning of the conductor and avoid too sudden changes of directions requiring bending the conductive cores and generating stresses harmful mechanics.
On peut prévoir entre deux chambres médianes côte à côte, une chambre 1 16 dite intermédiaire ayant les mêmes fonctions que la chambre médiane à savoir un moyen de serrage ou d'application des âmes l'une contre l'autre.It is possible to provide, between two median chambers side by side, a so-called intermediate chamber 1 16 having the same functions as the median chamber, namely a means for clamping or applying the cores against each other.
Vu de dessus, un tel connecteur pour deux câbles avec chambre intermédiaire aura une apparence de H.Seen from above, such a connector for two cables with an intermediate chamber will have an appearance of H.
De préférence, chaque connecteur aura une section externe approximativement circulaire comme le sont généralement les câbles électriques.Preferably, each connector will have an approximately circular external section as are generally the electric cables.
Avantageusement, la face externe du connecteur comprend des moyens d'association démontables avec un autre connecteur. Par exemple, on peut prévoir des moyens d'emboîtement, tels une empreinte recevant un plot ou encore un assemblage par glissière.Advantageously, the external face of the connector comprises removable association means with another connector. For example, it is possible to provide nesting means, such as an imprint receiving a stud or even a slide assembly.
Dans le cas d'un connecteur en H, les moyens d'emboîtement seront de préférence localisés au niveau de l'enveloppe délimitant la chambre intermédiaire. De préférence, la matière utilisée pour constituer le connecteur est bien évidemment une matière ayant des propriétés d'isolation électrique mais également des propriétés ignifuges. La liaison de conducteurs électriques peut ainsi se faire sans outil ce qui est très intéressant.In the case of an H connector, the fitting means will preferably be located at the level of the envelope delimiting the intermediate chamber. Preferably, the material used to form the connector is obviously a material having electrical insulation properties but also flame retardant properties. The connection of electrical conductors can thus be done without tools, which is very interesting.
Outre la visualisation du contact effectif entre les âmes, ces fenêtres permettent de visualiser le montage et notamment s'il y a ou non croisement des âmes conductrices.In addition to viewing the actual contact between the cores, these windows allow you to view the assembly and in particular whether or not there is a crossing of the conductive cores.
Un tel dispositif, réalisable en une seule opération d'injection et/ou moulage, présente un faible coût de production.Such a device, which can be produced in a single injection and / or molding operation, has a low production cost.
La taille et/ou volume du connecteur sont réduits et permettent de l'utiliser lorsqu'il y a peu d'espaces disponibles. II est à noter que, dans une variante de réalisation, une partie A de la paroi délimitant une chambre de verrouillage est indépendante du reste du connecteur de manière à pouvoir être rabattue indépendamment du reste B de la paroi.The size and / or volume of the connector are reduced and allow it to be used when there is little space available. It should be noted that, in an alternative embodiment, a part A of the wall delimiting a locking chamber is independent of the rest of the connector so as to be able to be folded down independently of the rest B of the wall.
Un tel connecteur peut donc être mis en attente sur un câble conducteur, les parties dénudées restant accessibles au monteur pour terminer la connexion.Such a connector can therefore be put on hold on a conductive cable, the stripped parts remaining accessible to the fitter to complete the connection.
Le boîtier isolant sera par exemple pourvu de trous 200 pour y engager des vis de fixation.The insulating housing will for example be provided with holes 200 for engaging fixing screws therein.
Au moins la chambre de verrouillage sera, sur ses bords latéraux, équipée de courtes 300 parois en saillie par rapport au plan de joint pour augmenter momentanément la profondeur de la cavité.At least the locking chamber will be, on its lateral edges, equipped with short 300 walls projecting from the joint plane to temporarily increase the depth of the cavity.
Comme on peut le voir sur les figures 4 et 5, les moyens d'assemblage des deux parties du connecteur comprennent d'un côté un élément formant à la fois une charnière 16 et un moyen de verrouillage.As can be seen in Figures 4 and 5, the means for assembling the two parts of the connector comprise on one side an element forming both a hinge 16 and a locking means.
Il s'agit dans cet exemple d'une lame courbée à l'une de ses extrémités pour s'accrocher sur un axe de pivotement que présente l'autre partie.In this example, it is a blade curved at one of its ends to hang on a pivot axis that the other part has.
A distance du crochet de cette lame 100, est prévu un ergot 1 10 qui vient s'engager dans des empreintes que porte cette partie.At a distance from the hook of this blade 100, a lug 1 10 is provided which engages in the imprints which this part carries.
Le moyen de verrouillage de l'autre côté du connecteur consiste en une lame droite portant également un ergot. On note que la chambre médiane est pourvue de rainures 500 transversales pour améliorer la pression sur les âmes conductrices. The locking means on the other side of the connector consists of a straight blade also carrying a lug. Note that the middle chamber is provided with transverse grooves 500 to improve the pressure on the conductive cores.
