Description

L'invention concerne le raccordement d'un dispositif électrique à un câble acheminant un flux d'informations, le raccordement consistant en une mise en série du dispositif avec le câble qui est un bus d'information.The invention relates to the connection of an electrical device to a cable carrying an information flow, the connection consisting in putting the device in series with the cable which is an information bus.

Il est courant dans une liaison reliant plusieurs dispositifs en série, d'avoir besoin d'ajouter un dispositif supplémentaire en série, ce qui se fait généralement en coupant le câble à l'endroit désiré et en reliant le dispositif audit câble ; cette manière de procéder nécessite une mise hors service de tous les dispositifs pendant la durée du raccordement.It is common in a link connecting several devices in series, to need to add an additional device in series, which is generally done by cutting the cable at the desired location and connecting the device to said cable; this procedure requires that all devices be taken out of service for the duration of the connection.

De telles liaisons série sont couramment utilisées dans les réseaux locaux de transmissions sur bus, le bus étant généralement un câble constitué par une paire blindée, pour la protection contre les perturbations électriques extérieures.Such serial links are commonly used in local bus transmission networks, the bus generally being a cable constituted by a shielded pair, for protection against external electrical disturbances.

L'invention a pour but le raccordement d'un dispositif à un bus, pour sa mise en série avec ledit bus en n'importe quel endroit du bus sans provoquer de perturbation importante du flux d'informations transitant par le bus, donc sans mise hors service de la liaison.The object of the invention is to connect a device to a bus, for putting it in series with said bus at any point on the bus without causing significant disturbance of the flow of information passing through the bus, therefore without setting out of service of the link.

L'invention a pour objet une prise de raccordement pour câble selon la revendication 1.The subject of the invention is a cable connection socket according to claim 1.

L'invention sera bien comprise par la description qui va suivre d'une prise de raccordement illustrée par les figures annexées dans lequelles :

  • la figure 1 est un schéma de principe d'une prise de raccordement de l'invention,
  • la figure 2 est une vue schématique de dessus d'une prise de raccordement de l'invention,
  • la figure 3 est une vue schématique en élévation, avec arrachement partiel, d'une prise de raccordement,
  • la figure 4 représente une pièce de contact utilisée dans la prise de raccordement,
  • la figure 5 est une vue en perspective d'une prise de raccordement.
The invention will be better understood from the following description of a connection socket illustrated by the appended figures in which:
  • FIG. 1 is a block diagram of a connection socket of the invention,
  • FIG. 2 is a schematic top view of a connection socket of the invention,
  • FIG. 3 is a schematic elevation view, partially broken away, of a connection socket,
  • FIG. 4 represents a contact piece used in the connection socket,
  • Figure 5 is a perspective view of a connection socket.

La figure 1 est un schéma de principe d'une prise de raccordement de l'invention. Le câble 1 est une paire blindée avec drain, 2 et 3 étant les fils de la paire, 4 le drain, 5 une gaine métallique de blindage revêtue d'une gaine isolante 60. Une échancrure de longueur L est pratiquée à l'endroit du raccordement, la gaine isolante extérieure du câble et la gaine métallique 5 étant enlevées ; de chaque côté de l'échancrure la gaine extérieure est enlevée sur une petite longueur L1, de manière à dégager la gaine métallique 5.Figure 1 is a block diagram of a connection plug of the invention. The cable 1 is a shielded pair with drain, 2 and 3 being the wires of the pair, 4 the drain, 5 a metallic shielding sheath coated with an insulating sheath 60. A notch of length L is made at the location of the connection, the outer insulating sheath of the cable and the metallic sheath 5 being removed; on each side of the notch the outer sheath is removed over a short length L1, so as to release the metal sheath 5.

L'échancrure permet d'accéder aux deux fils 2 et 3, et au drain 4 en contact métallique et électrique avec l'intérieur de la gaine métallique 5. Le fil 2 est relié, dans un support 50, à des pièces de contact 6 et 7 et le fil 3 est relié à des pièces de contact 8 et 9. Un câble de dérivation 20, blindé, comportant quatre fils 21, 22, 23, 24 relie un dispositif électrique 30 à la prise de raccordement ; les fils 21 à 24 sont reliés aux pièces de contact 6 à 9, respectivement. Les pièces de contact 6 à 9 sont du type à cisaillement d'isolant, de sorte que les fils 2 et 3 du câble 1 ne sont pas coupés. La mise en série du dispositif 30 avec les fils 2, 3, se fait par coupure des fils 2 et 3 entre les pièces de contact 6 et 7 d'une part et 8 et 9 d'autre part. Cette coupure est effectuée à l'aide d'un dispositif de coupure 10 coulissant dans un logement, au moment de la mise en service du dispositif 30.The notch provides access to the two wires 2 and 3, and to the drain 4 in metallic and electrical contact with the interior of the metal sheath 5. The wire 2 is connected, in a support 50, to contact parts 6 and 7 and the wire 3 is connected to contact parts 8 and 9. A branch cable 20, shielded, comprising four wires 21, 22, 23, 24 connects an electrical device 30 to the connection socket; the wires 21 to 24 are connected to the contact pieces 6 to 9, respectively. The contact parts 6 to 9 are of the insulating shear type, so that the wires 2 and 3 of the cable 1 are not cut. The device 30 is placed in series with the wires 2, 3, by cutting the wires 2 and 3 between the contact parts 6 and 7 on the one hand and 8 and 9 on the other hand. This switching off is carried out using a switching device 10 sliding in a housing, when the device 30 is put into service.

La continuité du blindage interne du câble 1 est assurée par un blindage 11 reliant les extrémités 5a et 5b de la gaine métallique 5 de chaque côté de l'échancrure. De même les extrémités 5a et 5b sont reliées par des blindages 12 et 13 à la gaine métallique 19 du câble 20 qui est situé sur une sortie latérale du support.The continuity of the internal shielding of the cable 1 is ensured by a shielding 11 connecting the ends 5a and 5b of the metal sheath 5 on each side of the notch. Similarly the ends 5a and 5b are connected by shields 12 and 13 to the metal sheath 19 of the cable 20 which is located on a lateral outlet of the support.

Par sécurité de continuité de masse le drain 4 est relié au blindage 11 par les contacts 35 et 36 placés de part et d'autre du dispositif de coupure 10 qui n'agit en aucune façon sur cette liaison de continuité.For safety of earth continuity, the drain 4 is connected to the shield 11 by the contacts 35 and 36 placed on either side of the cut-off device 10 which in no way acts on this continuity link.

Lorsque les fils 2 et 3 sont coupés, le dispositif 30 étant alors en série, il est possible de rétablir la continuité desdits fils 2 et 3 à l'aide de cavaliers de court-circuit 17, 18 reliant des pièces de contact 6 et 7 d'un part et 8 et 9 d'autre part. Lorsque les cavaliers sont en place cela permet par exemple la suppression du dispositif 30, ou encore son remplacement.When the wires 2 and 3 are cut, the device 30 then being in series, it is possible to restore the continuity of the said wires 2 and 3 using short-circuit jumpers 17, 18 connecting contact parts 6 and 7 on the one hand and 8 and 9 on the other. When the jumpers are in place this allows for example the removal of the device 30, or even its replacement.

La figure 2 est une vue schématique de dessus et la figure 3 est une vue schématique en élévation, avec arrachement partiel, d'une prise de raccordement de l'invention. Dans ces figures les mêmes références que dans la figure 1 ont même signification.Figure 2 is a schematic top view and Figure 3 is a schematic elevational view, partially broken away, of a connector of the invention. In these figures the same references as in Figure 1 have the same meaning.

Deux presse-étoupe 14 et 15 assurent le maintien du câble 1 sur le support 50 et l'étanchéité des jonctions entre le câble et le support. Les fils 2 et 3 sont disposés dans des goulottes 25 et 27 du support, le drain 4 étant disposé dans une goulotte 26 dans laquelle il est maintenu par des pièces de contact 35 et 36. Le support 5 comporte un logement constitué par deux compartiments 28 et 29 dans lesquels coulisse le dispositif de coupure 10. Le compartiment 28 est situé entre les pièces de contact 6 et 7, et le compartiment 29 est situé entre les pièces de contact 8 et 9 ; ces compartiments sont situés de part et d'autre de la goulotte 26, donc séparés par ladite goulotte 26 dans laquelle est disposé le drain 4.Two cable glands 14 and 15 maintain the cable 1 on the support 50 and seal the junctions between the cable and the support. The wires 2 and 3 are arranged in troughs 25 and 27 of the support, the drain 4 being disposed in a trough 26 in which it is held by contact pieces 35 and 36. The support 5 comprises a housing constituted by two compartments 28 and 29 in which the cutting device 10 slides. The compartment 28 is located between the contact pieces 6 and 7, and the compartment 29 is located between the contact pieces 8 and 9; these compartments are located on either side of the chute 26, therefore separated by said chute 26 in which the drain 4 is arranged.

La prise de raccordement comporte également un couvercle 51 et une semelle 52 isolants, et dont les parties en regard du support sont métallisées. Le couvercle 51 et le support 50 sont assemblés à l'aide de vis 40 qui se vissent dans des trous 42 du support, la semelle étant fixée par des vis 41 sur le support 50.The connection socket also comprises a cover 51 and an insulating sole 52, the parts of which facing the support are metallized. The cover 51 and the support 50 are assembled by means of screws 40 which are screwed into holes 42 in the support, the sole being fixed by screws 41 on the support 50.

Le dispositif de coupure 10, représenté en perspective figure 5, est en matière isolante ; il comporte deux branches 43, 44, chaque branche coulissant dans un compartiment et ayant une extrémité en forme de U dont les extrémités 45, 46 constituent deux couteaux qui coulissent le long des parois des compartiments perpendiculairement au fil à couper.The breaking device 10, shown in perspective in FIG. 5, is made of insulating material; it has two branches 43, 44, each branch sliding in a compartment and having a U-shaped end whose ends 45, 46 constitute two knives which slide along the walls of the compartments perpendicular to the wire to be cut.

Dans un compartiment ces deux couteaux viennent, en position basse, couper une portion 39 du fil comprise entre deux parois opposées du compartiment.In a compartment these two knives come, in the low position, to cut a portion 39 of the wire between two opposite walls of the compartment.

Dans la figure 3 le dispositif de coupure 10 est représenté en position basse, la position haute étant représentée en traits interrompus.In FIG. 3, the cut-off device 10 is shown in the low position, the high position being shown in broken lines.

Les pièces de contact 6, 7, 8 et 9 sont par exemple des pièces de contact doubles, comme représenté figure 4 ; les pièces de contact 35 et 36 des drains sont des pièces de contact du type à deux fourches opposées, comme cela est connu, soit encore des pièces de contacts doubles comme les pièces de contact 6, 7, 8, 9, afin d'être reliées électriquement à la métallisation interne du support, de la semelle et du couvercle, pour assurer la continuité de masse du câble 1.
La pièce de contact est en forme de double U avec une base 53 commune.The contact pieces 6, 7, 8 and 9 are for example double contact pieces, as shown in FIG. 4; the contact pieces 35 and 36 of the drains are contact pieces of the type with two opposite forks, as is known, or again double contact pieces like the contact pieces 6, 7, 8, 9, in order to be electrically connected to the internal metallization of the support, the sole and the cover, to ensure the earth continuity of the cable 1.
The contact part is in the form of a double U with a common base 53.

Un premier U est constitué par les branche A et B et un deuxième U est constitué par les branches C et D. Les branches A et B sont situées d'un côté de la base 53, et les branches C et D sont situées de l'autre côté de ladite base, les branches A et B étant à 90° des branches C et D. Chaque branche comporte une fente F pour cisaillement d'isolant, comme cela est bien connu. La pièce de contact permet le raccordement de deux fils isolés 3 et 23 ; le fil 3 étant inséré dans les branches A et B, son conducteur 54 vient en contact avec les bords des fentes F de ces branches ; le fil 23 étant inséré dans les branches C et D, son conducteur 55 vient en contact avec les bords des fentes F de ces branches. Les fils 3 et 23 sont perpendiculaires entre eux. Les pièces de contact 6, 7, 8 et 9 étant des pièces de contact doubles comme représenté figure 4, permettent le raccordement des câbles 1 et 20, figure 1, ces câbles étant perpendiculaires entre eux.A first U is constituted by the branches A and B and a second U is constituted by the branches C and D. The branches A and B are located on one side of the base 53, and the branches C and D are located from l on the other side of said base, the branches A and B being at 90 ° from the branches C and D. Each branch has a slot F for shearing insulation, as is well known. The contact piece allows the connection of two insulated wires 3 and 23; the wire 3 being inserted in the branches A and B, its conductor 54 comes into contact with the edges of the slots F of these branches; the wire 23 being inserted in the branches C and D, its conductor 55 comes into contact with the edges of the slots F of these branches. The wires 3 and 23 are perpendicular to each other. The contact pieces 6, 7, 8 and 9 being double contact pieces as shown in Figure 4, allow the connection of cables 1 and 20, Figure 1, these cables being perpendicular to each other.

La figure 5 est une vue schématique en perspective d'une prise de raccordement, montrant le dispositif de coupure 10 avant son introduction dans la prise, le couvercle 51 comportant une ouverture 57 à cet effet. Ce dispositif de coupure 10 comporte deux harpons tels que 56, un par branche 43, 44 du dispositif de coupure ; ces harpons sont situés du part et d'autre du dispositif de coupure et coopèrent avec le couvercle 51 en position basse, pour le maintien du dispositif de coupure dans cette position. La sortie de la prise, câble 20, se fait latéralement sur le côté de celle-ci ; un manchon isolé 58 assure le maintien et l'étanchéité du départ du câble 20.Figure 5 is a schematic perspective view of a connection socket, showing the cut-off device 10 before its introduction into the socket, the cover 51 having an opening 57 for this purpose. This cutting device 10 comprises two harpoons such as 56, one per branch 43, 44 of the cutting device; these harpoons are located on either side of the cut-off device and cooperate with the cover 51 in the low position, to maintain the cut-off device in this position. The outlet of the socket, cable 20, is made laterally on the side thereof; an insulated sleeve 58 maintains and seals the start of the cable 20.

La mise en place de la prise de raccordement de l'invention se fait de la manière suivante :

  • une échancrure est pratiquée dans le câble 1, à l'endroit désiré ;
  • les fils 2 et 3 et le drain 4 sont placés dans les goulottes 25, 26, 27 du support 50, au dessus des pièces de contact, 6, 7, 8, 9, 35 et 36,
  • les presse-étoupe 14 et 15 sont mis en place et le couvercle 51 est vissé sur le support 50 ; lors de la fixation, le couvercle presse sur les fils 2 et 3 et sur le drain 4 qui sont ainsi insérés dans les fentes F des pièces de contact.
  • Le dispositif de coupure 10 est introduit dans l'ouverture 57 du couvercle 51, et reste en position haute ; dans cette position les fils 2 et 3 ne sont pas coupés.
The establishment of the connection socket of the invention is done as follows:
  • a notch is made in the cable 1, at the desired location;
  • the wires 2 and 3 and the drain 4 are placed in the troughs 25, 26, 27 of the support 50, above the contact parts, 6, 7, 8, 9, 35 and 36,
  • the cable glands 14 and 15 are put in place and the cover 51 is screwed onto the support 50; during fixing, the cover presses on the wires 2 and 3 and on the drain 4 which are thus inserted into the slots F of the contact parts.
  • The cut-off device 10 is inserted into the opening 57 of the cover 51, and remains in the high position; in this position the wires 2 and 3 are not cut.

Le raccordement avec le dispositif 30 s'effectue semelle 52 retirée ; les fils 21, 22, 23, 24 du câble de dérivation 20, figure 1, sont introduits dans les branches inférieures des pièces de contact 6, 7, 8, 9, puis la semelle est vissée sur le support ; lors de la fixation de la semelle les fils 21 à 24 sont insérés dans les fentes des branches inférieures des pièces de contact.The connection with the device 30 takes place with the sole 52 removed; the wires 21, 22, 23, 24 of the branch cable 20, FIG. 1, are introduced into the lower branches of the contact parts 6, 7, 8, 9, then the sole is screwed onto the support; when fixing the sole, the wires 21 to 24 are inserted into the slots of the lower branches of the contact parts.

Le dispositif de coupure 10 est alors enfoncé, et prend la position basse ; les fils 2 et 3 sont coupés et le dispositif 30 est mis en série avec les fils 2 et 3 du câble 1.The cut-off device 10 is then pushed in, and takes the low position; the wires 2 and 3 are cut and the device 30 is placed in series with the wires 2 and 3 of the cable 1.

Il est également possible de monter d'abord la dérivation, c'est-à-dire le câble 20 sur la prise et d'effectuer ensuite le raccordement du câble 1, comme indiqué ci-dessus, la mise en service du dispositif 20, c'est-à-dire sa mise en série avec le câble se faisant en enfonçant le dispositif de coupure 10 après fixation du couvercle 51 sur le support 50. Les métallisation du support, du couvercle et de la semelle, en contact avec les gaines métalliques du câble 1 et du câble de dérivation 20 assurent la protection électromagnétique de la prise de raccordement.It is also possible to first mount the bypass, that is to say the cable 20 on the socket and then carry out the connection of the cable 1, as indicated above, the commissioning of the device 20, that is to say it is placed in series with the cable by pushing in the cutting device 10 after fixing the cover 51 on the support 50. The metallization of the support, the cover and the sole, in contact with the sheaths of the cable 1 and the branch cable 20 ensure the electromagnetic protection of the connection socket.

La proéminence du dispositif de coupure 10 indique visuellement si la dérivation est opérationnelle (10 enfoncé et vérouillé en position basse) ou non (10 proéminent et verrouillé en position haute).The prominence of the cut-off device 10 visually indicates whether the bypass is operational (10 pushed in and locked in the low position) or not (10 prominent and locked in the high position).
