Definitions

  • the invention relates to a connector, for a multicore cable intended for the transmission of weak currents and electromagnetically shielded, which is intended to ensure the wired connection of equipment in series on the cable, the latter comprising at least one pair of insulated wires and electromagnetic shielding, of the metal sheath type to which a conductive drain is possibly associated and electrically connected.
  • the creation of local multiple station networks uses in particular information transmission links in digital form, the transmission medium of which consists of a common multiconductor cable, most often an electromagnetically shielded cable comprising two insulated wires.
  • a plurality of equipments for example of processors and / or compatible terminals are then connected together in series via the common cable along which they are distributed.
  • the trend is to be able to deliver network cabling comprising the common cable along which are mounted and connected all the individual connectors and the branch cables making it possible to connect the equipment to be served to the cable, via the connectors.
  • the branch cables of such cables are sometimes themselves connected to components of the equipment served, for example to the transceiver units of this equipment which are then housed in appropriate boxes.
  • Such cabling thus equipped is capable of being stored on reels for their transport and each cabling is unwound and directly installed on site, the connection operations being thus greatly reduced.
  • all the equipment is not necessarily put into service upon installation, it is not useless for the connectors to be able to be mounted on the cables without necessarily being inserted in series on the link, when the equipment to be served is not in place, since the electrical connection in series would then be likely to be interrupted at the connector and / or the connection cable concerned. It is also important that connectors can be added later.
  • the invention as defined by claim 1 therefore provides a connector for a multiconductor cable intended for the transmission of low currents and electromagnetically shielded, which is provided for ensuring the wired connection of equipment in series on the cable, this connector being arranged to have a simple and reliable assembly and connection, to allow the storage of the branch cable that it serves with the main cable, after assembly and at least partial connection, to withstand the forces associated with the installation along the path of the common cable and to optionally allow mounting and connection at any point of a common cable already equipped or installed.
  • EP-A-0 400 521 which belongs to the state of the art according to art. 54 (3) EPC and which describes a similar but not identical branch connector.
  • Document US-A-4 284 316 describes an insulation displacement connection block.
  • the block has grooves to accommodate wires to be connected and conductive elements which cut the insulation from the wires when pressed.
  • Figure 1 shows an electrical diagram of the connector allowing the serial connection of equipment by through conductive wires on an electromagnetically shielded multiconductor cable.
  • Figure 2 shows a schematic top view of the lower part of a connector according to the invention, wired.
  • Figure 3 shows an exploded perspective view of the connector according to the invention.
  • Figure 4 shows a schematic top view of the lower part of the connector.
  • Figure 5 shows a longitudinal section along v-V of the assembled connector.
  • Figures 6 to 9 respectively show an example of a connecting part in front view, left, from above and in perspective.
  • FIG. 10 shows a block for connecting parts and a connector connection cover, in perspective and seen from above, with the shielding blade and in parallel with the connecting parts.
  • Figure 11 shows the connection piece support block, in perspective and seen from below.
  • Figure 12 shows the connector connection cover, in perspective and seen from below, with the shielding blade.
  • Figure 13 shows the connector slider in exploded perspective and seen from above.
  • Figure 14 shows the connector slide, without cutting blades, in perspective and seen from below.
  • the connector 1 schematically presented in FIG. 1 is intended to allow the connection in series of a low current equipment, not shown, for example a computer terminal, to a first cable 2, multiconductor and electromagnetically shielded, by means of wires conductors most often belonging to a second cable 3, the first cable, often called bus, then being intended to connect the equipment considered to other identical or compatible equipment, for the exchange of information transmitted in the form of digital signals.
  • the cables are electromagnetically shielded.
  • the first cable used to connect the equipment served usually comprises at least two conductive wires 2A, electrically isolated, for the transmission of signals and an electromagnetic shielding 2B which sheaths them, the assembly itself being sheathed by at least one or more insulating layers.
  • the first cable is composed of a pair of conductive wires insulated from each other and commonly housed in a metal shielding sheath.
  • This sheath is preferably associated with a drain 2C intended to serve as a ground conductor at the level of the possible connectors, as can be seen in FIG. 2; this ground conductor is for example constituted by a multi-strand metal wire placed parallel to the two insulated wires in the sheath which encloses them and with which it is electrically in contact along the cable.
  • the ground conductor 2C is used here to ensure the electrical continuity of the shielding sheath 2B, when the cable 2 must be opened for the installation of a connector 1, the latter involving the elimination of a portion of the shielding sheath and the 2D insulating sheathing which covers it to access the 2A wires transmitting the signals.
  • the connector 1 is capable of receiving other cables, in particular if the shielding of these comprises a part comparable to a multiconductor wire at the level of an opening made in the cable, in a chosen location along this cable, for the installation of a connector.
  • the second cable 3 is likely to be a cable as defined above or more conventionally a cable in which the insulated conducting wires, here referenced 3A or 3A ′, are housed under a shielding sheath 3B, without drain, in particular when this second cable is only connected at its ends, the shielding sheath itself being covered with at least one 3D insulator.
  • the connector 1 is intended to allow the connection in series on the cable 2 of an equipment to be served, which implies the use of two pairs of conductive wires between the connector and the equipment, as seen in Figure 1, these two pairs of wires 3A and 3A 'most often belonging to the same cable 3, in the shielding sheath 3B from which they are placed.
  • the connector 1 provides for the introduction of the second cable 3 in parallel with the first cable 2 which passes right through the connector, as can be seen in FIG. 2. This avoids the total cutting of the first cable at the connectors and in particular to ensure uninterrupted ground continuity along this first cable, via the shielding sheath 2B and, in the embodiment presented, the ground conductor 2C.
  • the introduction of the second cable 3 into the connector 1 parallel to the first cable 2, here arranged longitudinally, offers the additional advantage of facilitating storage on a reel of a first cable equipped with connectors provided with their second cables and possibly with space-saving elements belonging to the equipment served, not shown here.
  • the connector 1 therefore comprises a support block 5 on which the connection pieces 6 are positioned, allowing the different wires 3A, 3A ′ to be connected in pairs to the wires 2A respectively on either side of a central zone where the wires 2A will be interrupted to allow the serialization of the equipment to be served.
  • the ground conductor 2C of the cable 2 passes centrally through the support block 5 without being interrupted, while the corresponding shielding sheath 2B is annularly cut as well as the sheathing which covers it, at the location chosen for the connector 1, so to give access to the wires 2A and consequently to the ground conductor 2C.
  • the cutting of an annular portion of cable 2 which surrounds the shielding sheath 2B, with a view to eliminating this portion, is carried out for example using a cutting tool capable of alternately splitting peripherally or longitudinally the external insulating sheathing of the cable.
  • the shielding sheaths 2B, 3B which are also cut peripherally are shown folded down on the insulating sheathing of the cables of which they are part to form conductive rings intended to come to rest on corresponding surfaces 8 of the bottom of the housing 9 in which the support block 5 is housed - see Figure 3 -.
  • Conductive flanges 10 immobilize the bottom of the housing 9 on the cable 2 at the two ends of this housing and on the cable 3, the electrical conduction between the flanges and the bottom of the housing 9 which is electrically conductor being provided by the fixing screws 11, an electrical continuity is thus established between the shielding sheaths 2B and 3B as well as with the bottom of the housing by means of the flanges and screws.
  • the shielding sheath 2B is cut with the 3D insulating sheathing which covers it, at the same level as it, on either side of the area where the wires 2A and the ground conductor 2C are released for the connection to be made via the connector 1, the flanges 10 coming to grip the cable 2 on its 2D insulating sheath and the cable 3 on its braid 3B. This in fact simplifies the assembly process.
  • Figures 3 and 5 show all the components of the connector according to the invention which also includes a cutting arrangement intended to be positioned in the central area of interruption of the wires 2A and constituted by a cutting slide 13 cooperating with the support block 5 and with a connection cover 12 which is placed here on this support block.
  • the assembly thus formed is enclosed in the housing formed by the bottom of the housing 9 and a complementary cover 14.
  • the bottom 9 and the cover 14 of the housing are fitted one on the other and here fixed by means of screws 15, the heads of which open onto the cover and are secured in columns 16 projecting from the bottom 9.
  • the housing 9,14 is sealed by a set of seals, such as 17,18 shown here respectively positioned in a groove 19 in the plane seal between the bottom and the cover of the box and at the three cable entries 2 and 3 in this box - see figures 3,4 and 5 -.
  • the support block 5 detailed in FIGS. 4, 5, 10 and 12, has an upper plate provided with grooves for the wires 2A, 3A, 3A ′ and for the earth conductor 2C. This is housed in a central groove 20C on either side of which are placed two lateral grooves 20A where the two wires 2A of the first cable are housed respectively.
  • These lateral grooves 20A each have a central cavity 21, these cavities are arranged on either side of the central groove under the grooved plate and are intended to receive one end of one of the wires 2A after it has been cut by the 'one of the two knives 22 - Figure 13 - that comprises the slide 13 as well as this knife and the slide part which carries it.
  • Two pairs of grooves 23A and 23A ′ which are blind, unlike the through grooves 20A and 20C, open at one end of the support block 5 parallel to the other grooves; they are each intended to receive one end of one of the wires 3A, 3A ′ to be connected to a wire 2A.
  • These grooves each terminate next to a groove provided for one of the wires 2A, the two grooves 23A terminating on either side of the assembly formed by the grooves 20A, 20C on the other side of the cavities 21 relative to the grooves 23A ′ which also terminate on either side of the assembly formed by the grooves 20A, 20C.
  • connection piece 6 is used to electrically connect each of the wires 3A, 3A ′ to one or the other of the wires 2A, each connection piece 6 is positioned on the one hand at the bottom of a groove 20A and on the other leaves at the blind end of the adjacent groove 23A or 23A ′, here overlapping the border separating these two grooves.
  • connection pieces 6 are identical and are positioned symmetrically both with respect to the central groove 20C and transversely to it.
  • Each piece 6 comprises two connection units, parallel, each capable of receiving an insulated wire in two slots 6A for stripping and holding wire, as seen in FIGS. 7 and 8.
  • the part 6 is produced by cutting and folding from a strip of conductive strip.
  • One of the connection units intended to be housed in one of the grooves 20A comprises a longitudinal base 6B extending on either side of the connection unit under which it is placed.
  • One of the two ends 6C of each base is positioned at the edge of the cavity 21 which opens in the groove 20A at the bottom of which the base is housed as seen in FIG. 4; each end 6C adjoining a cavity 21, forms one of the two cutting blades used for slicing the wire 2A contained in the groove where the cavity opens, during the placing in series on a cable 2 of an equipment served by the connector 1 considered.
  • connection units the slots 6A of which are formed, according to a conventional arrangement, by oblique folding and one towards the other of trapezoidal extensions 6D; initially parallel, they are joined by a bridging 6E which here overlaps the border separating two adjacent grooves 20A and 23A or 23A ′ at the level of a positioning notch 25 - see FIG. 10 -.
  • connection pieces The insertion of the wires 2A, 3A and 3A ′, into the slots 6A of the connection pieces is intended to be carried out preferably with the aid of a tool making it possible to obtain placement under optimal conditions that are easily reproducible, in particular if connections are made at the factory, possibly automatically using machines.
  • a tool of the type described in international application PCT / FR87 / 00837 and in European application 0265321, is preferably used and the cover 12 includes fixing means similar to those provided in the requests mentioned above for a connection tool, similar to that described in these requests.
  • the cover 12 has as many orifices 26 for inserting and positioning the tool as there are connection units, that is to say two orifices 26 per part 6, each overhanging the two slots of the connection unit to which it is assigned.
  • the complementary cover 12 is secured on the support block 5 on which it rests and fits, the securing being ensured for example by a system of fastening tabs 27 carried by the complementary cover and latching onto lateral projections 28 of the support block and by the penetration of two positioning studs 34 of the cover into complementary housings 35 of the support block -figures 10 and 11 -.
  • the orifices 26 are rectangular and are each provided with a rectangular projection 29 at the center of which the orifice 26 opens. The latter through which comes into translation an insertion blade of rectangular section of the tool.
  • the end of this tool which carries the movable insertion blade comes at least partially to cover the rectangular projection 29, the orifice 26 of which internally has hooking flanges 30, here longitudinal, - Figures 5 and 10 -, for elements fixing mobile which are carried by the tool and which are able to penetrate into the orifice 26 before the insertion blade to hang on the flanges 30 in immobilizing the tool with respect to the cover 12 - support block 5 assembly, during actuation of the insertion blade, during the connection of a wire.
  • the movable fastening elements of the tool are for example constituted by two flexible blades secured to the end of the tool where the insertion blade slides on either side of this insertion blade with which they project. Each of the two blades ends in a bead, so that the two bead-bearing ends are pressed against each other when the insertion blade is retracted, which allows their insertion into an orifice 26.
  • the outlet of the insertion blade by sliding between the two blades forming the movable fixing means causes the beads to spread under the flanges in the orifice 26 and prevents the tool from being withdrawn until the insertion blade has been retracted again, by an appropriate mechanism which it is not justified to describe here.
  • the insertion blade is for example longitudinally grooved to pass between the edges of the extensions 6D which determine each of the two slots 6A of a connection unit, it comes by longitudinal sliding to penetrate into an orifice and to penetrate into the two slots 6A that it overhangs by pressing transversely on the conductor previously positioned in the corresponding groove of the support block 5, perpendicular to the two slots which it overhangs.

  • the connection of equipment in series on the cable 2 via the cable 3 involves cutting the wires 2A at the level of the cavities 21.
  • a cutting slide 13 is positioned above the conductors 2A at the level of the cavities 21, in which it penetrates by cutting each of the wires at a point and driving one of the two ends of each of the two wires cut into one of the cavities 21 in order to separate it definitively from the end, formed by the cut, with which it was previously continuous.
  • the slide 13 comprises a support body 31 made of molded insulating material, which is capable of sliding in a guide 32, here of rectangular section formed in the cover 12 above the cavities 21 when the cover 12 is in place on the support block 5 - Figures 5.11, 13 and 14.

  • Each cutting blade 22B has a cutting edge 22C which touches a cutting end 6C and runs along the wall of the cavity 21 which is located perpendicularly under the groove 20A to the right of this cutting end when the connection piece which includes this end 6C is in place.
  • Each cutting blade 22B extends laterally beyond its cutting edge 22C by a guide rib 22D, the end 22E of which is folded backwards to facilitate engagement of the cutting blade 22B against the cutting end 6C corresponding to the introduction of the extension which carries this blade in the cavity 21 bordered by said cutting end.
  • Each extension 31B of the carrier body 31 has a guide wall which extends it and is situated practically in the same plane as the face of the cutting blade 22B which cooperates with the corresponding cutting end 6C, when the connector 1 is assembled.
