Description

La présente invention concerne les dispositifs de connexion électrique permettant de raccorder deux câbles à brins multiples, et notamment les câbles électriques utilisés dans la recherche géophysique.The present invention relates to electrical connection devices making it possible to connect two cables with multiple strands, and in particular the electrical cables used in geophysical research.

Les dispositifs de connexion de câbles pour recherche géophysique sont généralement constitués d'une paire de connecteurs hermaphrodites présentant chacun une face de connexion électrique qui est reliée à un câble à brins multiples. Chaque face de connexion comprend un groupe de conducteurs mâles et un groupe de conducteurs femelles. La réunion des deux faces de connexion établit la liaison électrique entre le câble relié à un connecteur et le câble relié à l'autre connecteur.Cable connection devices for geophysical research generally consist of a pair of hermaphrodite connectors each having an electrical connection face which is connected to a multi-strand cable. Each connection face includes a group of male conductors and a group of female conductors. The union of the two connection faces establishes the electrical connection between the cable connected to one connector and the cable connected to the other connector.

Etant donné que les lieux des terrains explorés en recherche géophysique sont extrêmement variés les dispositifs du genre précité doivent résister aussi bien aux conditions dues à la nature du sol (sable, boue, eau, neige, glace) qu'aux conditions atmosphériques (froid, chaleur, humidité, pluie) rencontrées dans ces lieux. Leur étanchéité doit donc être assurée vis-à-vis des facteurs énumérés précédemment. Celle-ci est réalisée généralement par un joint élastique qui est comprimé au moment de l'accouplement des connecteurs par la mise en oeuvre des moyens de verrouillage. Cette mise en oeuvre doit pouvoir être faite rapidement par un personnel non qualifié.Given that the locations of the terrains explored in geophysical research are extremely varied, the devices of the aforementioned kind must withstand both the conditions due to the nature of the soil (sand, mud, water, snow, ice) as well as atmospheric conditions (cold, heat, humidity, rain) encountered in these places. They must therefore be sealed against the factors listed above. This is generally carried out by an elastic seal which is compressed at the time of coupling of the connectors by the use of the locking means. This implementation must be able to be done quickly by unqualified personnel.

Les dispositifs de connexion électrique existant utilisés pour raccorder deux câbles électriques ne satisfont pas entièrement à ces conditions car ils présentent généralement au moins un des inconvénients suivants :

  • - difficulté de mise en oeuvre des moyens de verrouillage à basse température d'où la néces-. sité d'utiliser un outillage spécialisé ;
  • - grippage possible des moyens de verrouillage par suite de l'introduction de particules étrangères à l'intérieur de rainures de verrouillage, ce qui se répercute défavorablement au niveau de l'étanchéité ;
  • - moyen de verrouillage n'indiquant pas ou qu'imparfaitement la fin de course d'où risque de déverrouillage ou de défaut d'étanchéité.
The existing electrical connection devices used to connect two electrical cables do not fully satisfy these conditions because they generally have at least one of the following drawbacks:
  • - difficulty in implementing the locking means at low temperature, hence the need. sity to use specialized tools;
  • - Possible seizure of the locking means as a result of the introduction of foreign particles inside the locking grooves, which has an adverse effect on the seal;
  • - locking means that do not indicate or only imperfectly the end of travel, hence the risk of unlocking or leakage.

Un dispositif de l'art antérieur, décrit dans le brevet américain, US 3 745 511 comprend des moyens de connexion électrique pour le raccordement de câbles à brins multiples dans lequel des leviers de verrouillage sont montés sur les connecteurs femelle sur lesquels ils sont maintenus en place. Des anneaux de verrouillage sont solidaires respectivement de ces leviers. Chaque anneau de verrouillage comporte des rainures inclinées coopérant avec des ergots ; ces ergots formant des parties saillantes qui ne sont pas portés par le corps de connecteur.A device of the prior art, described in the American patent, US 3,745,511 comprises electrical connection means for the connection of multi-strand cables in which locking levers are mounted on the female connectors on which they are held in square. Locking rings are respectively secured to these levers. Each locking ring has inclined grooves cooperating with lugs; these lugs forming projecting parts which are not carried by the connector body.

Dans le but de remédier aux inconvénients des dispositifs antérieurs, la présente invention a pour objet un dispositif de connexion électrique pour le raccordement de câbles à brins multiples comprenant une paire de connecteurs hermaphrodites présentant chacun une face de connexion électrique composée d'un groupe de conducteurs de connexion mâles et d'un groupe de conducteurs de connexion femelles reliés à un câble à brins multiples, ces groupes étant montés de façon à pouvoir être connectés respectivement à des groupes de conducteurs de connexion femelles et mâles de la face de connexion électrique, reliée à un câble à brins multiples de l'autre connecteur hermaphrodite, chaque connecteur étant muni en outre de moyens de verrouillage mécanique pour assurer l'interconnexion électrique et mécanique des groupes de conducteurs engagés l'un dans l'autre, ainsi que la compression de moyens élastiques assurant l'étanchéité du dispositif à l'état verrouillé, les moyens de verrouillage de chaque connecteur comprenant un étrier de verrouillage monté sur le corps du connecteur de façon à pouvoir pivoter entre une position où les deux connecteurs sont déverrouillés et mobiles séparément, et une position où les deux connecteurs sont verrouillés, ce verrouillage s'effectuant par la rotation des étriers derrière des faces terminales respectivement des couvercles des connecteurs, rotation au cours de laquelle des parties saillantes sur les corps des deux connecteurs sont engagées dans des moyens prévus dans les étriers de verrouillage.In order to remedy the drawbacks of previous devices, the present invention relates to an electrical connection device for the connection of multiple-strand cables comprising a pair of hermaphrodite connectors each having an electrical connection face composed of a group of conductors of male connectors and of a group of female connection conductors connected to a multi-strand cable, these groups being mounted so that they can be connected respectively to groups of female and male connection conductors of the electrical connection face, connected to a multi-strand cable from the other hermaphroditic connector, each connector being further provided with mechanical locking means to ensure the electrical and mechanical interconnection of the groups of conductors engaged one inside the other, as well as the compression of elastic means ensuring the tightness of the device in the locked state, the locking means of each a connector comprising a locking bracket mounted on the body of the connector so as to be able to pivot between a position where the two connectors are unlocked and movable separately, and a position where the two connectors are locked, this locking being effected by the rotation of the stirrups behind terminal faces respectively of connector covers, rotation during which projecting parts on the bodies of the two connectors are engaged in means provided in the locking stirrups.

Les objets et caractéristiques de la présente invention apparaîtront plus clairement à la lecture de la description suivante d'exemples de réalisation, ladite description étant faite en relation avec les dessins ci-annexés dans lesquels :

  • La figure 1 représente une vue en perspective de la paire de connecteurs hermaphrodites qui compose un dispositif de connexion électrique selon la présente invention.
  • La figure 2 représente une vue d'un côté longitudinal du dispositif après l'assemblage de la paire de connecteurs hermaphrodites montrée par la figure 1. Pour faciliter la compréhension, un élément est montré verrouillé et l'autre en cours de verrouillage.
The objects and characteristics of the present invention will appear more clearly on reading the following description of exemplary embodiments, said description being made in relation to the attached drawings in which:
  • FIG. 1 represents a perspective view of the pair of hermaphrodite connectors which makes up an electrical connection device according to the present invention.
  • Figure 2 shows a view of a longitudinal side of the device after assembly of the pair of hermaphrodite connectors shown in Figure 1. To facilitate understanding, one element is shown locked and the other being locked.

Les connecteurs hermaphrodites 10 et 11, montrés par la figure 1 sont équivalents par leur fonction électrique et la forme de leur corps. Celui 10 en haut de la figure 1 est plus particulièrement vu de dos et celui 11 en bas de cette figure est vu par sa face 12 de connexion électrique.The hermaphroditic connectors 10 and 11, shown in FIG. 1 are equivalent by their electrical function and the shape of their body. The one 10 at the top of Figure 1 is more particularly seen from the back and the one 11 at the bottom of this figure is seen by its face 12 of electrical connection.

Les deux connecteurs 10 et 11, se trouvent dans la position où leur accouplement est possible par simple raccordement des deux faces 12 et 13 de connexion électrique. Chacune de ces faces 12 et 13 se compose d'un groupe 14 de conducteurs de connexion mâles (non représentés) qui est logé dans une alvéole 16 de forme cylindrique, et d'un groupe 15 de conducteurs de connexion femelles (non représentés) logé également dans une alvéole 17 de forme analogue à la précédente et qui est contiguë à celle-ci.The two connectors 10 and 11 are in the position where their coupling is possible by simple connection of the two faces 12 and 13 of electrical connection. Each of these faces 12 and 13 consists of a group 14 of male connection conductors (not shown) which is housed in a cell 16 of cylindrical shape, and of a group 15 of female connection conductors (not shown) housed also in a cell 17 of shape similar to the and which is contiguous to it.

Les groupes de conducteurs d'un connecteur sont chaque fois raccordés de la manière désirée aux brins de l'un des câbles 18 et 19 à brins multiples qui doivent être raccordés par ce dispositif. Les conducteurs mâles et femelles sont complémentaires, c'est-à-dire que les conducteurs mâles et femelles d'un connecteur peuvent être accouplés respectivement aux conducteurs femelles et mâles de l'autre connecteur.The groups of conductors of a connector are each connected in the desired manner to the strands of one of the cables 18 and 19 with multiple strands which are to be connected by this device. The male and female conductors are complementary, that is to say that the male and female conductors of one connector can be coupled respectively to the female and male conductors of the other connector.

Le passage des brins d'un câble et leur raccordement aux conducteurs de connexion logés dans les alvéoles 16 et 17 se fait dans un compartiment (non visible) aménagé entre une paroi 20 supportant les deux alvéoles 16 et 17 et une paroi extérieure 21 ou dorsale du connecteur. Cette paroi 21 est de préférence celle d'un couvercle protégeant l'ensemble des liaisons électriques internes établies avec le câble. Ce dernier, par exemple le câble 18 est raccordé à travers un manchon 23 cylindrique qui est solidaire d'une partie terminale 28 du corps du connecteur 11.The passage of the strands of a cable and their connection to the connection conductors housed in the cells 16 and 17 takes place in a compartment (not visible) arranged between a wall 20 supporting the two cells 16 and 17 and an outer wall 21 or back of the connector. This wall 21 is preferably that of a cover protecting all of the internal electrical connections established with the cable. The latter, for example the cable 18 is connected through a cylindrical sleeve 23 which is integral with an end portion 28 of the body of the connector 11.

L'axe de ce manchon 23 est aligné sur les centres successifs des deux alvéoles 16 et 17 et confondu avec l'axe de symétrie longitudinal du connecteur.The axis of this sleeve 23 is aligned with the successive centers of the two cells 16 and 17 and coincides with the longitudinal axis of symmetry of the connector.

Sur chaque corps de connecteur est monté un étrier de verrouillage 24, en forme de U, qui peut pivoter par ses deux bras 25 et 26 parallèles entre eux sur un axe transversal 27 fixé à la paroi 21 du couvercle et qui est perpendiculaire à l'axe de symétrie longitudinal du corps du connecteur. Cet axe transversal 27 est de préférence situé près du côté terminal 28 du corps du connecteur qui est solidaire du manchon 23.On each connector body is mounted a locking bracket 24, U-shaped, which can pivot by its two arms 25 and 26 parallel to each other on a transverse axis 27 fixed to the wall 21 of the cover and which is perpendicular to the longitudinal axis of symmetry of the connector body. This transverse axis 27 is preferably located near the terminal side 28 of the body of the connector which is integral with the sleeve 23.

L'étrier de verrouillage 22 ou 24 peut pivoter entre une position où les deux connecteurs 10 et 11 sont déverrouillés et mobiles séparément et une position où ils sont verrouillés. Le verrouillage s'effectue par l'engagement de parties saillantes 30 et 31 externes des corps des deux. connecteurs 10 et 11, dans des crans 34 prévus sur chaque pièce 32 qui est attachée rigidement aux extrémités des deux bras de chaque étrier 22 et 24.The locking bracket 22 or 24 can pivot between a position where the two connectors 10 and 11 are unlocked and movable separately and a position where they are locked. Locking is effected by the engagement of external projecting parts 30 and 31 of the bodies of both. connectors 10 and 11, in notches 34 provided on each part 32 which is rigidly attached to the ends of the two arms of each stirrup 22 and 24.

L'écartement des deux bras 25 et 26 est déterminé pour qu'en position de verrouillage ils longent le corps du connecteur sur lequel ils sont montés. Une poignée 35, qui relie les deux bras et qui permet d'actionner l'étrier de verrouillage, est dans ce cas rabattue derrière une face terminale 29 du connecteur qui se trouve à l'opposé de la face terminale 28 à laquelle est raccordé le câble relié au connecteur.The spacing of the two arms 25 and 26 is determined so that in the locked position they run along the body of the connector on which they are mounted. A handle 35, which connects the two arms and which makes it possible to actuate the locking stirrup, is in this case folded down behind an end face 29 of the connector which is located opposite the end face 28 to which the connector is connected. cable connected to the connector.

Les parties saillantes 30 et 31 sont constituées de préférence par des extrémités d'une tige 36 qui est disposée du côté de . la face 12 de connexion, transversalement au sens axial longitudinal, et du côté terminal 29 opposé à celui 28 raccordé au câble.The protrusions 30 and 31 preferably consist of ends of a rod 36 which is arranged on the side of. the connection face 12, transversely to the longitudinal axial direction, and on the terminal side 29 opposite to that 28 connected to the cable.

Les extrémités de la tige 36 sont portées par deux montants 37 et 38 qui sont solidaires d'un support 39 plat vissé à la paroi 20 portant les deux alvéoles 16 et 17.The ends of the rod 36 are carried by two uprights 37 and 38 which are integral with a flat support 39 screwed to the wall 20 carrying the two cells 16 and 17.

A chaque extrémité des bras des étriers 22 et 24 de verrouillage est fixée rigidement une pièce plate 32 qui présente une forme de secteur de cercle, ce qui permet de faire porter par celle-ci aussi bien des moyens de pivotement 40 montés sur l'axe transversal 27 que d'y pratiquer une gorge 33 circulaire centrée sur les moyens de pivotement 40 et dont un bord interne comporte le cran 34.At each end of the arms of the locking stirrups 22 and 24 is rigidly fixed a flat part 32 which has the shape of a sector of a circle, which makes it possible to carry therewith both pivot means 40 mounted on the axis transverse 27 than practicing there a circular groove 33 centered on the pivoting means 40 and an internal edge of which comprises the notch 34.

Les gorges 33 sont réalisées, par exemple en étant un peu plus larges que les parties saillantes correspondantes 30 et 31, de manière telle que les bords des gorges 33 contribuent à une assistance au verrouillage et au -déverrouillage du connecteur. Cette assistance a lieu par coopération entre les parties saillantes 30 et 31 et un bord des gorges 33 qui forme came lors du verrouillage des connecteurs et l'autre bord lors du déverrouillage de ceux-ci. On bénéficie ainsi d'un effet de bras de levier extrêmement utile. On notera à cet égard que la force d'insertion et de désolidarisation des connecteurs géophysiques peut atteindre plusieurs dizaines de daN.The grooves 33 are made, for example by being a little wider than the corresponding projecting parts 30 and 31, so that the edges of the grooves 33 contribute to assistance in locking and unlocking the connector. This assistance takes place by cooperation between the projecting parts 30 and 31 and one edge of the grooves 33 which forms a cam when the connectors are locked and the other edge when the connectors are unlocked. This provides an extremely useful leverage effect. It will be noted in this regard that the force of insertion and separation of the geophysical connectors can reach several tens of daN.

Les moyens de pivotement 40 du secteur 32 comprennent de préférence un perçage dans l'angle de rotation du secteur et des moyens usuels pour le maintenir sur l'axe 27, tels que vis ou encore un aplatissement de l'extrémité de l'axe 27 au dehors du perçage.The pivot means 40 of the sector 32 preferably comprise a bore in the angle of rotation of the sector and usual means for holding it on the axis 27, such as a screw or even a flattening of the end of the axis 27 outside the hole.

Les deux bords longitudinaux du corps d'un connecteur sont parallèles à son axe de symétrie longitudinal. A leurs deux extrémités s'élève chaque fois une paroi 44, qui s'arrête au voisinage de l'alvéole 16 qui lui est contiguë, et de hauteur inférieure à celle-ci. Dans chaque paroi est prévue une encoche 41 destinée à supporter les extrémités 30 et 31 de la tige 36 qui y sont introduites au moment de l'accouplement des deux faces 12 et 13 de connexion électrique.The two longitudinal edges of the body of a connector are parallel to its longitudinal axis of symmetry. At their two ends rises each time a wall 44, which stops in the vicinity of the cell 16 which is contiguous to it, and of height less than the latter. In each wall is provided a notch 41 intended to support the ends 30 and 31 of the rod 36 which are introduced therein at the time of the coupling of the two faces 12 and 13 of electrical connection.

La figure 2 montre le dispositif selon l'invention où l'un 24 des étriers est en position de verrouillage et l'autre étrier 2 dans une position précédant le verrouillage.Figure 2 shows the device according to the invention where one 24 of the stirrups is in the locking position and the other stirrup 2 in a position preceding the locking.

Avant l'accouplement des deux faces 12 et 13, les bras des étriers 22 et 24 sont dirigés vers l'extérieur de leur couvercle 21. Au cours de celui-ci, on place en même temps les extrémités saillantes 30 et 31 des tiges 36 dans les encoches 41 respectives de chaque connecteur. Puis les étriers 22 et 24 sont pivotés de manière à engager les extrémités 30 et 31 saillantes des tiges 36 d'un connecteur successivement dans les gorges 33 et le cas échéant les crans 34 respectifs de l'étrier de l'autre connecteur. En fin de verrouillage, les poignées 35 de chaque étrier sont rabattues dans le sens de la flèche F derrière la face terminale du couvercle 21. Une indication précise sur l'état de verrouillage du dispositif est fournie par la position des extrémités 30 et 31 saillantes dans les crans 34 respectifs.Before the coupling of the two faces 12 and 13, the arms of the stirrups 22 and 24 are directed towards the outside of their cover 21. During this, the projecting ends 30 and 31 of the rods 36 are placed at the same time in the respective slots 41 of each connector. Then the stirrups 22 and 24 are pivoted so as to engage the projecting ends 30 and 31 of the rods 36 of a connector successively in the grooves 33 and if necessary the respective notches 34 of the stirrup of the other connector. At the end of locking, the handles 35 of each stirrup are folded in the direction of arrow F behind the end face of the cover 21. A precise indication of the locking state of the device is provided by the position of the projecting ends 30 and 31 in the respective notches 34.

Du fait du montage symétrique de ces deux ensembles à étrier, le verrouillage simultané des deux étriers 22 et 24, chacun étant dans une main de l'opérateur, entraîne en outre par la coopération entre les quatre gorges 33 et les parties saillantes correspondantes 30 et 31 un guidage linéaire progressif des deux connecteurs lors de leur verrouillage et de leur déverrouillage.Due to the symmetrical mounting of these two stirrup assemblies, the simultaneous locking of the two stirrups 22 and 24, each being in one hand of the operator, further results by the cooperation between the four grooves 33 and the corresponding projecting parts 30 and 31 a guide progressive linear of the two connectors when they are locked and unlocked.

Pour assurer l'étanchéité du dispositif ainsi verrouillé, un joint interfacial élastique (non représenté) est interposé préalablement entre le bord circulaire de l'alvéole 17 du connecteur 11 et le pourtour du groupe logé dans l'alvéole 16 de l'autre connecteur 10. Ce joint étant ainsi comprimé exerce une force opposée à la force de compression, d'où une poussée tendant à maintenir les extrémités saillantes 30 et 31 des tiges 36 d'un connecteur dans les crans 34 respectifs de l'étrier de l'autre connecteur.To seal the device thus locked, an elastic interfacial seal (not shown) is interposed beforehand between the circular edge of the socket 17 of the connector 11 and the periphery of the group housed in the socket 16 of the other connector 10 This joint being thus compressed exerts a force opposite to the compression force, from where a push tending to maintain the projecting ends 30 and 31 of the rods 36 of a connector in the respective notches 34 of the stirrup of the other connector.

Le dispositif de connexion électrique ainsi réalisée peut être nettoyé facilement. L'ensemble du corps du dispositif est de préférence moulé dans une matière plastique robuste, par contre les tiges 36 et les étriers qui sont fortement sollicités sont réalisés en métal.The electrical connection device thus produced can be easily cleaned. The entire body of the device is preferably molded in a robust plastic material, on the other hand the rods 36 and the stirrups which are highly stressed are made of metal.

Le dispositif peut être pourvu en outre de contacts 43 électriques permettant d'établir une connexion téléphonique par câble. Ces contacts peuvent par exemple traverser la paroi de son couvercle 21 et être reliées aux brins d'un câble.The device can also be provided with electrical contacts 43 making it possible to establish a telephone connection by cable. These contacts can for example pass through the wall of its cover 21 and be connected to the strands of a cable.
