Definitions

  • the present invention relates to a connector for shielded flat cable, that is to say, a cable of flattened rectangular section comprising in an insulating matrix a plurality of conductive tapes of flattened section arranged in parallel in one or more rows between two layers. conductive forming ground planes and extending over most of the width of the cable.
  • Such cables can be used in many applications where it is necessary to ensure effective shielding of the conductors of a cable against the external environment, as much to avoid disturbing the external environment by parasitic signals in from the cable only to protect the cable conductors from extraneous signals from the outside.
  • Such shielded cables must naturally be able to be connected to structural elements such as for example printed circuits and the present invention specifically relates to a connector making it possible to ensure such a connection while preserving the continuity of the shielding effect between the cable and the structure to be connected.
  • the connector according to the invention is essentially characterized by the fact that it comprises a plug and a receptacle capable of being joined by locking means, the plug comprising an insulating body provided with recesses for receiving and retaining the cable conductors , a cover cap whose at least the inner wall is conductive surrounding said body, recesses being provided between said cover and the plug body for receiving the conductive sheets forming the ground plane of said cable, the base comprising an insulating body capable to be engaged in said plug and comprising contacts capable of coming into contact with the conductors of the cable housed in said plug, said base body comprising over at least part of its length a conductive envelope capable of coming into contact with the wall inside of the plug body cover.
  • the ends of the plies forming the ground plane of the cable housed in the plug are folded back on themselves, the elastic support being effected in the folded area.
  • the envelope can advantageously have one or more projecting parts such as tabs cut out of the envelope and which are compressed when the plug is engaged on the base.
  • Elastic support elements such as leaf springs can also advantageously be provided in the plug body for resiliently pressing the cable conductors held in the plug body against the contacts of the base when the plug is engaged on the 'base to form the connector.
  • This cable generally designated by 1 comprises in an insulating matrix 2 conductive tapes of flattened section 3, fourteen in number in the example illustrated, arranged in two rows between two conductive shielding plies 4, 5 which extend practically over any the width of the cable.
  • FIGS. 2 to 5 illustrate a connector according to the invention intended to receive a flat cable with two rows of conductive tapes such as that of FIG. 1.
  • the connector consists of a plug generally designated by 6 (Figure 2) and a socket 7 illustrated in Figure 3.
  • the plug 6 comprises an insulating body 8 intended to receive the conductive tapes 3 of the cable, the body 8 being covered by a cover 9, conductive or preferably made of a plastic material provided on its inner wall 10 with a metallic coating.
  • the cable is introduced through an end opening 11 of the cover of the plug and its insulating matrix is sectioned parallel to the main faces of the cable so as to separate the shielding plies 4 and 5 and the conductors 3.
  • the conductors 3 which, as can be seen in FIG. 3, are stripped over part of their length, penetrate the body of the plug and are then folded back from a cusp of a wall 12 of the insulating body of the conductor, the stripped part extending in a recess 13 produced between the wall 12 and the inner wall 10 of the cover, the non-stripped end of the conductors 3 being engaged in recesses in the form of a slot 14 in the body of the hood.
  • the stripped parts of the conductors 3 are pushed outwards by leaf springs 15 bearing on the walls 12.
  • the shielding plies 4 and 5 of the cable not exposed on one of their faces are introduced into the orifice 11 of the cover in a recess 16 of substantially L-shaped section formed between the cover and the body 8 of the plug, the end of each of the layers 4 and 5 being folded back on itself from a cusp.
  • elastic members are provided such as leaf springs 17 or elastomer support parts 18 housed in body cavities of sheet.
  • the base 7 illustrated in FIG. 3 comprises an insulating body 19 capable of being engaged in the recesses 13 of the plug body and containing contacts 20 capable of coming, as illustrated in FIG. 3, in contact with the conductors 3 of the cable .
  • the base body 19 comprises at least on its main faces and over a part of its height, from the free end of the contacts 20, a conductive casing 21 fixed on projections 22 of the body 19, the casing 21 having cut tabs 23 projecting outwards and capable of being pressed elastically against the internal wall 10 of the cover of the plug when the latter is engaged on the base as illustrated in FIG. 4.
  • the immobilization of the connector elements is ensured by snap-fastening, as can be seen in FIG. 5, by engagement of pawls 24 projecting externally from the cover 9 of the plug in the holes 25 provided for this purpose in the wall of the base.
  • FIG. 4 which illustrates the connection of a cable such as that of FIG. 1 to a printed circuit board C via a connector according to the invention produced by assembling a base according to FIG. 3 and a plug according to FIG. 2, an electrical continuity of ground planes is obtained between the cable and the printed circuit board ensuring perfect shielding with respect to outside.
  • the plies 4 and 5 of the cable are in contact with the conductive inner wall 10 of the cover, then the continuity of the ground plane is ensured by means of the conductive envelope 21 of the base, the ends of which 21 ′ are as seen in Figure 4 plugged into the printed circuit board C.
