Definitions

  • the present invention relates to a vehicle antenna automobile likely to receive an active impedance adapter as well as an active impedance adapter assembly for such antenna.
  • the strand of an antenna must have a certain length suitable for this reception; when he is desirable, for implantation reasons, to limit the length of the antenna strand, an active impedance adapter is used antenna, i.e. an impedance adapter supplied with electrical power, the role of which is to reinforce the signal received by the antenna to compensate for this reduction in length; indeed, a too long antenna is not without problems: difficulties of maneuvering in individual garages with generally low ceilings, difficulties during automatic vehicle washing operations, whistling at high speed, or other.
  • the antenna strand is generally supported by a base; so far the active antenna impedance adapter is in a independent box placed near the radio receiver or the base, or inside the base itself; such a provision, which requires a particular assembly, is bulky and inconvenient when the antenna is intended to equip a motor vehicle.
  • the active impedance adapter When the active impedance adapter is inside the base, it it is necessary that it has a height suitable for receiving it; a such height then leads to a base that is too high when it is not decided to add an active impedance adapter to the antenna; in in addition, the base being placed outside the passenger compartment of the vehicle, the active impedance adapter is subjected to thermal stresses that are detrimental to him.
  • the object of the present invention is to avoid the drawbacks above and for object an antenna capable of receiving a Space-saving active impedance adapter, associated with the base classic antenna.
  • an active antenna impedance adapter consisting of a plate in the form of a flat washer, one of the faces of the plate carrying an annular conductive outlet track coming in support against the annular core part and the other face carrying a track conductive input ring on which the means comes to bear contact, the face of the plate which carries the entry track bearing also the electrical means of adaptation of an adaptation circuit electrically powered by a power supply terminal carried by said plate, the output track being connected to the circuit output terminal adaptation through a metallized hole through the plate, a ground terminal of said adaptation circuit being electrically connected to the annular mass element of the nozzle.
  • the element integral with the male element is an insulating ring carried by the base, and the centering surface of the insulating annular part is a cylindrical recess formed in the insulating annular piece.
  • the centering surface of the annular part insulating is an annular spacer which is pressed against the face inside of the annular core part and which cooperates with the element male.
  • the annular spacer came from molding with the insulating annular piece; the annular spacer has a axial annular extension on which the annular part is centered lady.
  • the annular mass element consists an annular grounding piece and an annular piece of mass.
  • the male element of the organ connection is a threaded rod secured to the base, and the female element is a nut carrying the contact means and screwed onto the rod.
  • the male element of the connecting member is the threaded rod of a head screw and the female element is a tapping that comprises the base, the contact means being formed by the head of the screw.
  • the contact means rests directly on the part ring finger.
  • the active adapter is placed in a case consisting of a cylindrical skirt held by clipping by the element mass annular tip; the adapter ground terminal active is connected to ground by a pin secured to the housing.
  • the case is closed by a cover.
  • the base carries clipping pins for clipping the base on the edges of an opening of the element body.
  • the insulating annular piece carries at least a baluster; the baluster is adapted to be received in a chimney provided in the base, the chimney having ribs or beads to increase the retention effect of the clipping pins on the body element.
  • the present invention also relates to a set consisting of an active adapter, a housing, a protector and a cover, these components being as used in the antenna having the characteristics mentioned above.
  • an antenna base 30 for a motor vehicle such a known base is generally made up of a part hollow molded plastic material defined by a shaped wall general frustoconical developed from a base in general form ellipse surrounded at its lower part by a sealing lip in support on a bodywork element 40; at the top of the base 30, a metal pin, for example made of brass, not shown, internally threaded, is intended to receive the threaded end externally from an antenna strand; this metal pin is in contact electric with a metal support covered by plastic of the base 30 and comprising a male element in the form of a threaded rod 31 intended to receive a female element in the form of a tightening nut 32; at its exit from the base 30, the threaded rod 31 is surrounded by material plastic constituting an insulating ring 42; when the base 30 is placed on the bodywork element 40, the insulating ring 42 passes through a opening 41 of the bodywork element 40; a paw

  • Such a tip 20 is known and of the kind which is described, for example, in FR-A-2 563 946.
  • the assembly of the assembly is carried out in the manner next.
  • such a tip 20 is arranged so as to allow the addition, if desired, of an active adapter impedance; in the case of an adaptation of the antenna signal, it is essential that the annular core piece 24 of the end piece 20 does not touch not the threaded rod 31, in which case the adaptation circuit would be short-circuited ; to avoid that manufacturing tolerances do not lead centering the end piece 20, by cooperation of the insulator 42 of the base 30 with the cylindrical recess 44 of the annular part insulating 23, insufficient from this point of view, the central hole 29 of the part annular core 24 is provided large enough for this contact be avoided for sure.

  • the plate 10 is intended to be threaded on the threaded rod 31 of the base 30; therefore, the insulating part of the printed circuit double-sided has a suitable central opening 19 having a diameter slightly greater than that of the threaded rod 31; for some reasons which will appear more clearly below, the exit track 12 of annular shape has its small diameter which is larger than that of the central opening 19, while the small diameter of the entry track 14, also of annular shape, is at most equal to the diameter of said central opening 19.

  • the insulating annular piece 223 also differs from the annular part 123 in that the centering surface is produced by a axial annular extension 169 on which the part is centered annular core 224, the external face of the extension 169 flush with the external face of the annular core piece 224; so this is the thickness radial of the extension 169 which physically defines the space isolation between the threaded rod 131 and the annular core piece 224.
  • the assembly when assembled and mounted, is axially compact under bodywork element 140, which fits well behind a vehicle where the space available inside the vehicle between the roof of the vehicle and the interior trim is more reduced than at the front; for this reason also, the supply wire 76 is mounted transversely to the wafer 100, as illustrated in dashed lines in Figure 6.
  • 145 clip pins are provided on the edge of the insulator 142 of the base 130 for momentary clipping thereof on the edges of the opening 141 of the bodywork element 140; since inside the vehicle, it is then possible to mount the sub-assembly constituted by the end piece 120, the housing 150, the plate 100 and the protector 170 on the base by inserting the balusters 139 in the chimneys 138 of base 130; longitudinal ribs 147 are provided inside the chimneys 138, in line with the insulation 142, the balusters 139 thus being momentarily held by tightening elastic of the material, and it is possible to let go of the subset, present and screw the screw 151; the introduction of the balusters 139 in the chimneys 138 swells, due to the ribs 147, the material of the insulation 142, which reinforces the holding effect of the clips 145 on the bodywork element 140.
  • each bead 247 is at straight a picot 145; the beads 247 play the same role, described above, than that of the balusters 139; chimneys 138 can also have a slightly conical shape, as visible on the figure 8.
