Definitions

  • the present invention relates to a multi-channel electrical connector without an electromagnetic barrier between the channels.
  • each channel being constituted by a coaxial contact element comprising a central conductor and an external conductor, means for connection to a printed circuit board and an electrically conductive rod connecting the central conductor of the contact element coaxial with said connection means.
  • these partitions constitute an obstacle to the miniaturization of the connector, which must necessarily comprise n ⁇ 1 partitions for n rods, hence a certain bulk.
  • the present invention aims to provide a multi-channel electrical connector which in particular does not have the drawbacks mentioned above.
  • the present invention relates to a multi-way electrical connector, in which each channel is constituted by a coaxial contact element comprising a central conductor and an external conductor, means for connection to a printed circuit board and an electrically conductive rod connecting the conductor central of the contact element coaxial with said connection means, characterized in that the conductive rods are housed in a housing which defines a continuous interior space, delimited by at least one ground plane, each conductive rod being disposed near at least one of said ground planes and being separated from the neighboring conductive rod or rods by a distance greater than the distance which separates it from its ground plane.
  • the connector according to the invention has the advantage of being able to be miniaturized in large proportions while being of a relatively low cost price.
  • the conductive rods are housed in a dielectric medium whose dielectric constant is determined so that, taking into account the diameter of each rod and the distance which separates this rod from its plane or planes mass, the impedance of each channel has a desired value.
  • the connector comprises a second dielectric medium of different dielectric constant which separates the first dielectric medium from the ground plane (s).
  • the conductive rods can be placed in a first dielectric medium consisting of air and bear against a layer of plastic material applied to the ground plane, this layer of plastic material constituting a second dielectric medium.
  • the housing is preferably made of an electrically conductive material and plays the role of shielding from the outside.
  • a single ground plane preferably formed by a wall of the housing, and in the vicinity of which the conductive rods are arranged.
  • two parallel ground planes are provided, preferably constituted by two walls of the housing and between which the conductive rods are arranged.
  • a printed circuit board 1 on which is mounted a connector 2 comprising a metal support 3 in the shape of an L, the lower branch 4 of which is secured to the plate 1 and has holes 5 provided with insulating sheaths 6 through which the ends of two bent conductive rods 7 engage.
  • the metal support 3 and the ends of the conductive rods 7 are fixed to the printed circuit board 1 by conventional means, in particular by welding.
  • Each conductive rod 7 is connected to the central conductor 8 of a coaxial contact element 9 whose external conductor 10 is welded to the upper branch 11 of the metal support 3.
  • a metal cover 12 of parallelepiped shape, having an open bottom and front face, is removably mounted on the metal support 3 by fixing means, not shown, to constitute a housing within the meaning of the invention.
  • This housing defines a continuous interior space in which the two conductive rods 7 are housed.
  • the two conductive rods 7 are placed between these two ground planes.
  • the conductive rods 7 are spaced from each other by a distance D equal to 4 mm.
  • the conductive rods 7 are located near one of the walls 14 of the metal cover.
  • the distance between the conductive rods 7 of the other wall 13 of the metal cover is large enough that the influence on the conductive rods 7 of this other wall 13 can be considered negligible, or even zero, from the electromagnetic point of view.
  • the cover 12 fulfills a shielding function vis-à-vis the outside, as in the previous embodiment.
  • a second dielectric material 15 consisting of a layer of PTFE (polytetrafluoroethylene ), whose dielectric constant K2 is 2.
  • the impedance Z of each electrical line is approximately 50 ⁇ :
  • the second dielectric medium 15 provides an advantage concerning the manufacture of the housing 12 by constituting a shim which makes it possible to position the conductive rods 7 at a desired distance from the ground plane 14 by applying them against this layer 15.
  • the connector 2 ′ comprises a metal housing 3 ′ which has, in a plane parallel to the printed circuit 1, a U-shaped section visible in FIG. 5.
  • the housing 3 In its front part 16, which forms the base of the U in FIG. 5, the housing 3 'is full and has two bores 17 in which the external conductors 10 engage, which are welded or force-fitted into the bores 17.
  • the housing 3 ' In its rear part 18, which forms the two branches of the U in FIG. 5, the housing 3 'has two parallel flat walls 13', 14 '.
  • the rear end 19 of the housing 3 ' is open.
  • the two conductive rods 7 are overmolded in a block of dielectric material 15 ′ made for example of polyimide.
  • the dimensions of the block 15 ' correspond substantially to the internal dimensions of the space between the walls 13' and 14 'of the housing 3'.
  • the block 15 ' is intended to be inserted into the housing 3' between its two parallel walls 13 'and 14', as seen in FIG. 5.
  • Each conductive rod 7 engages inside the corresponding external conductor 10 and its end 8 'directed towards the front part 18 of the housing constitutes the central conductor of a coaxial contact 9' thus produced.
  • the rear face 19 of the housing can be closed off by an electrically conductive plate, not shown, intended to constitute an electromagnetic shield against the exterior of the housing.
