Definitions

  • a connector for flat cable including parallel spaced apart elongate conductors in a dielectric sheath comprises a body including two relatively movable parts defining therebetween a channel adapted to receive the flat cable.
  • the parts include sets of spaced apart parallel grooves and ribs, the ribs of one part facing the grooves of the other and vice versa, with conducting teeth disposed in the grooves of both parts and one additional conducting tooth protruding from a rib.
  • the teeth of one part are electrically interconnected and those of the other part are individually connected to output contacts. When the parts are brought together, the teeth penetrate the sheath of the cable and contact respective conductors, one set of alternate conductors being connected together and to one grounding contact and the other alternate conductors being individually connected to respective contacts.
  • the invention relates to connectors for flat cable of the type including a plurality of spaced apart parallel conductors within a flexible dielectric sheath.
  • the present invention aims to provide a connector for flat cable which can be adapted directly either onto a printed circuit for example, enabling an automatic cabling of the grounded conductors between themselves and towards the output, requiring no stripping, nor a particular precision of the spacing between the conductors of the cable, and enabling interface components to be interconnected without intermediary cabling.
  • a connector for flat cable of the type including a plurality of parallel spaced apart elongate conductors within a flexible dielectric sheath, comprising a dielectric body including two parts defining therebetween a channel adapted to receive a flat cable, the parts being movable relative to one another between a first position in which a flat cable can be introduced into the channel and a second position in which a flat cable in the channel is gripped between the parts, each part carrying a row of spaced apart electrically conducting teeth adapted when the parts are moved from the first position to the second position to pierce the dielectric sheath of a flat cable gripped therein and come into contact with the conductors, a pair of teeth of the two parts being aligned so as to come into contact with a common conductor and the other teeth being non-aligned with the teeth of the opposite part so as to each come into contact with a respective one of the conductors, the teeth of one part being electrically interconnected together and the teeth of the other part being
  • FIG. 1 is a schematic cross-section of a flat cable to be connected
  • FIGS. 2 and 3 are schematic explanatory diagrams of a connector according to the invention prior to and after setting up a connection;
  • FIG. 4 is a cross-section taken along line IV-IV of FIGS. 7 of a specific embodiment of a connector according to the invention.
  • FIG. 5 is an elevational view looking from the righthand side of FIG. 4;
  • FIG. 6 is an elevational view looking from the lefthand side of FIG. 4.
  • FIG. 7 is a partial cross-section taken along line VI-VI of FIG. 4.
  • the flat cable shown in FIG. 1 includes a plurality of parallel spaced apart elongate electrical conductors l and 2 within a flexible dielectric sheath 3, the five conductors 1 being intended to be active and the seven conductors 2 being intended to be passive, i.e., grounded.
  • the active and passive conductors are disposed alternately, with the exception of two passive conductors 4 and 5 placed side by side at one edge of the cable.
  • the connector according to the invention is schematically shown in FIGS. 2 and 3.
  • the connector comprises a case 6 and a mobile part 7 slidably mounted inside the case 6.
  • the case 6 and the mobile part 7 include sets of facing parallel apart grooves and ribs, the ribs of the case 6 facing the grooves 7a of the part 7, and the ribs of the part 7 facing the grooves 6a of case 6.
  • the part 7 has a transverse conducting plate 20 provided with pointed teeth 21 protruding in the grooves 7a and one particular pointed tooth 22 extending beyond the other teeth and protruding from a rib.
  • the case 6 includes conducting parts 24 and 25 insulated from one another and provided with pointed teeth protruding in the grooves 6a.
  • the conducting parts 24 and 25 are individually connected to contacts 8 accessible from outside the case 6.
  • the other passive conductors 2 and 4 are pressed in the grooves 7a where they come to meet the teeth 21 of the conducting plate 20, so that all of the passive conductors are electrically connected to the conducting part 25 through the point 22, the conductor 5, and the tooth of part 25. Of course, in operation, the part 25 is grounded.
  • FIGS. 2 and 3 A specific embodiment of the connector schematically shown in FIGS. 2 and 3 will now be described with reference to FIGS. 4 to 7.
  • a substantially rectangular case is formed of two parts 6 and 10 in which a wedge-like mobile part 7 is longitudinally slidably movable and can be moved by means of a screw 9.
  • a cover 11, which can be clipped onto a rear end of part 6, includes orifices l2 and 13 adapted to face electrical output contacts 8 of the connector.
  • a guide channel 14 of rectangular section adapted to receive an end of a flat cable.
  • the outer portion of the channel 14 leads to an elongate opening chamfered at 15 and 16 so as to facilitate the introduction of a cable, this outer portion of the channel 14 being disposed parallel to the general direction of elongation of the case 6 and to the axis of screw 9.
  • An inner portion of channel 14 is disposed obliquely to the general direction of elongation of case 6 and is defined between sets of facing parallel spaced apart grooves and ribs, the grooves 6a of part 6 being disposed opposite the ribs of part 7, and vice-versa, and the width of each groove and rib being equal to the spacing between adjacent conductors of the flat cable.
  • the grooves 6a and 7a are tapered at 6b and 7b to smoothly join with the outer portion of channel 14, so that a flat cable can be easily inserted along the channel, the part of the cable in the oblique portion bearing against the outer surfaces of the facing ribs.
  • the part 7 carries a transversal conducting metal plate 20, disposed parallel to the base of the outer portion of channel 14, provided with a set of teeth 21 each protruding in a groove 7a and one particular tooth 22, longer than the others, protruding from a rib and facing a groove 6a.
  • the number of teeth of plate is equal to the number of conductors of the flat cable which are to be grounded, namely seven in the illustrated example.
  • the part 6 of the case has a shoulder 23 in which planar conducting plates 24 are disposed perpendicular to the base of the outer portion of channel 14 and parallel to the axis of movement of part 7, and being of a number equal to the number of conductors of the cable which are to be active, namely five in this example.
  • a sixth conducting plate 24, identical to the plates 24, is disposed parallel to the plates 24.
  • the plates 24 and 25 each have two cutting teeth 26 and 27 protruding in the grooves 6a, these teeth having cutting ends spaced apart on either side of the plane of plate 20.
  • the conducting plates 24 and 25 are electrically insulated from one another and are individually electrically connected to an equal number of contacts, for example clips such as 8, accessible from the exterior of the case through openings 12 of the cover 11. If the connecting pins of a circuit or plug adapted to be plugged into the connector have a smaller section than that of the pins 28 shown, as is the case for example with a printed circuit, the openings 13 may be used. To do this, the cover 11 is removed, turned by 180 and fitted back on, the extension 29 coming to engage the clips 8 and thus reducing the gripping space in the clips 8, the pins being guided by a channel 30 provided between extensions 29 and the lower arm of clips 8.
