Definitions

  • the present invention relates to an antenna base intended to support an antenna strand for a motor vehicle, said base having a nut carried by a support provided with unidirectional mounting means.
  • an antenna strand used in particular for the operation of a radio telephone and / or a radio set, on board the motor vehicle, is electrically connected, via a base, to the antenna cable (s), the base being deposited on a bodywork element of the vehicle at the opening provided therein, while the antenna cable extends from the 'other side of the bodywork element relative to the antenna strand.
  • the base consists of a hollow piece of molded plastic material carrying a metal fixing pin intended to receive the antenna strand and a metal support secured to the hollow piece, said support comprising a cylindrical skirt bearing externally a thread receiving a tightening nut.
  • the object of the present invention is to solve this problem, by making such mounting particularly easy.
  • a base of the above type is characterized in that the tightening nut is a captive nut carried by a nut support provided with one-way mounting means cooperating with the external thread of the cylindrical skirt of said support.
  • said support carries unidirectional holding means of said support on a bodywork element of the vehicle, the directions in which the holding means and the mounting means are operational being the same but in opposite directions; preferably, the holding means are means of elastic clip housed in a groove formed on the outer surface of a positioning zone of said support which extends along the cylindrical skirt; the positioning zone is placed in line with the bodywork element which has an opening through which the positioning zone passes, the positioning zone and the opening having sections which correspond, apart from the assembly clearance; according to a preferred embodiment, the section of the positioning zone and that of the opening of the bodywork element are rectangular; the holding means extend along two parallel sides of the opening in two parallel grooves in the positioning zone; the positioning zone carries a keying pin extending axially in a keying notch formed on an edge of the opening of the bodywork element.
  • the mounting means consist of an inner lip ring arranged axially between a transverse bearing surface of the nut support and the captive nut; the body element is metallic and a metal ground washer with claws is disposed axially between the body element and the nut support also provided in metal.
  • the nut support is provided with a central chimney and a gutter with U-section arranged transversely with respect to the chimney into which it opens, the chimney and the gutter defining an L-shaped passage for the cable.
  • the chimney extending in the support and in the cylindrical skirt along their axis and the gutter crossing a longitudinal notch provided in the wall of the skirt; a radially elastic cylindrical ring is disposed between the support and the chimney; a cover closes the gutter.
  • the nut support is integral with a housing intended to receive electrical means associated with the antenna; when the chimney is closed by a cover, preferably the cover also closes the housing.
  • Electrical insulation means are arranged around the antenna cable inside the chimney and the gutter.
  • the figures show a base intended for mounting an antenna strand, not shown, on a bodywork element 19 of a motor vehicle.
  • the base consists of a hollow part 11 molded in plastic material defined by a wall 2 of generally frustoconical shape developed from a base 3 in general shape of ellipse surrounded at its lower part by a sealing lip 4 bearing on the bodywork element 19.
  • the wall 2 is extended by a boss 5 of frustoconical external shape now by overmolding a metal fixing pin 9, for example made of brass; pin 9 is internally threaded and is intended to receive an externally threaded end of the antenna strand not shown, axis 6 the pin 9 and the boss 5 being inclined towards the rear of the motor vehicle.
  • a metal fixing pin 9 for example made of brass
  • pin 9 is internally threaded and is intended to receive an externally threaded end of the antenna strand not shown, axis 6 the pin 9 and the boss 5 being inclined towards the rear of the motor vehicle.
  • the hollow piece 11 of plastic material covers a support 12 made of metal, for example of zamak, having a transverse face 8 opposite the external face of the bodywork element 19; the support 12 is extended upwards to the vicinity of the frustoconical boss 5 so that it surrounds the fixing pin 9 over a large part of its height to constitute an electrical shielding, an insulating material 44 electrically insulating the fixing pin 9 relative to the metal support 12.
  • the metal support 12 comprises a cylindrical skirt 13 externally carrying a thread 14 receiving a tightening nut 15.
  • the nut 15 is carried by a nut support 16 having a cylindrical wall 38, surrounding the cylindrical skirt 13 of the metal support 12 and the end of which supports the nut 15 in the manner of a captive nut: to do this, the wall 38 of the nut support 16 is provided at its end with a circular rim 57 for centering extended along lugs 46, for example three legs 46 arranged at one hundred and eighty degrees, folded down in a circular groove 45 formed at the periphery of the nut 15; thus, the nut 15 is integral with the nut support 16 while being able to rotate relative to it.
  • the circular groove 45 is inclined in the direction shown in the figure, that is to say that the bottom of the groove 45 is closer to the transverse face outer of the nut than is the entry of the groove: thanks to this arrangement, it is enough to push the nut 15 towards the nut support 16 so that automatically by cooperation with the inner edge lower inclined groove 45 the legs 46 are folded into the groove 45 and hold the nut 15 axially while allowing it to be able to rotate relative to the nut support 16. It is also possible, of course, to fold the legs 46 in the groove 45 conventionally using a folding tool, the groove 45 in this case not necessarily being inclined.
  • the nut support 16 is provided with mounting means 17 consisting of a ring, for example made of plastic, having on its inner surface an elastic conical lip 25 directed towards the lower end of the wall 38 of the nut support 16; the ring 17 is housed inside the cylindrical wall 38 of the nut support 16 and held axially by cooperation, on one side, with a transverse bearing surface 26 defined by a radial recess 43 of the interior surface of the wall 38 and, on the other side, with the upper end face of the nut 15; the diameter of the inner cylindrical surface of the ring 17 is such that, when the ring 17 is threaded on the cylindrical skirt 13 of the support 12, only its inner lip 25 interferes with the external thread 14 of the skirt 13; taking into account the direction of inclination of said lip 25, the mounting of the ring 17 on the skirt 13 is unidirectional: the ring 17 is movable upward relative to the skirt 13 but is retained in the opposite direction by cooperation of the lip 25 with thread 14; the nut support 16 - nut 15 - ring 17 assembly
  • the base For mounting the base on the bodywork element 19, the latter has an opening 22 of rectangular shape having a notch 24 on one of its sides; the support 12 has a positioning zone 21 which extends perpendicularly from the support face 8 of the support 12 and which extends along the cylindrical skirt 13; the outer surface of the positioning zone 21 has a section equal, apart from the mounting clearance, to that of the opening 22 of the bodywork element 19, including the notch 24 which thus receives a pin 23 extending axially carried by the positioning zone 21: the notch 24 and the pin 23 therefore constitute a notch and a keying pin making it possible to ensure that when the base is mounted on the bodywork element, the axis 6 of the pin 9 and the boss 5 is inclined well towards the rear of the vehicle.
  • a resilient metal washer 27 called mass is placed on the upper surface of the nut support 16 and surrounds the positioning zone 21; it has a central recess 48 of also rectangular shape corresponding to the section of the positioning zone 21; on two parallel sides of the recess 48 are provided notches 49 for the passage of the coding pin 23; the washer 27 has an axis of symmetry parallel to said two parallel sides where the notches 49 are provided: this arrangement gives to the washer 27 two positions, one hundred and eighty degrees from each other, according to which it can be mounted, which makes assembly easier; according to these said two parallel sides, the washer 27 is provided with elastic tabs 47, bent at ninety degrees, intended to be received in slots 54 presented by the nut support 16 for holding the washer 27 on said support d 'nut 16; at its periphery, the washer 27 carries claws 28 inclined on either side of the mean plane of the washer 27; these claws 28 are intended to ensure good electrical contact between the metal part of the bodywork element 19 and the nut support 16 which is thus connected to ground.
  • the nut support 16 is also provided with a central chimney 29 carried by a gutter 30 with a U-section arranged transversely with respect to the central chimney 29 into which it opens; the central chimney 29 is received in a bore 7 extending along the axis of the cylindrical skirt 13 by opening, on one side, inside said skirt 13 and, on the other side, inside the housing of the support 12 which receives the insulator 44; a notch 31 radially crossing the wall of the skirt 13 and that of the positioning zone 21 allows the passage of the gutter 30; a radially elastic cylindrical ring 33 is interposed between the chimney 29 and the bore 7; this ring 33 makes it possible to participate, by friction, in maintaining the nut support 16 relative to the support 12, before tightening the nut 15, thus helping in this function the mounting means 17 in the form of a ring.
  • the chimney 29 and the gutter 30 are intended for the angled mounting of an antenna cable 42; indeed, as is known, most antenna installations on board a vehicle require that the antenna cable 42 extend, inside the vehicle body, along the element of body 19 to join, directly or indirectly, the radio device and / or telephone with which the vehicle is equipped.
  • the antenna cable 42 is connected to a connector 242 for its connection to the antenna cable itself.
  • the stripped end of the antenna cable reveals the metallic core 53 of the cable 42 which is electrically connected, by welding or crimping, to a metallic socket 51 adapted to receive a pin.
  • insulation means 36 are provided between the spindle 50, the socket 51 and the cable 42, on the one hand, and the chimney 29, on the other hand; similarly, other insulation means 37 are provided between the cable 42 and the gutter 30;
  • the insulation means 36-37 may be two cylindrical elements, one of which has the axis of the chimney 29 and the other of which has an axis perpendicular to the previous one; they can also be produced in the form of two L-shaped half-shells with a semicircular section, connected according to a joint plane corresponding to the plane formed by the two above axes, that is to say parallel to the plan of figure 6.
  • one-way holding means 18 consist of elastic clipping means produced in the form of lip bars 55 housed in grooves 20 of trapezoidal section extending on either side of the positioning zone 21 parallel to the side of the opening 22 which bears the keying notch 24; on the side of this notch, the groove 20 passes through the coding pin 23; the elastic lips 55 of the holding means 18 bear on the inner face of the bodywork element 19 to axially retain the support 12.
  • This sub-assembly is then mounted from below the body element 19 on the support 12, the chimney 29 and its elastic ring 33 taking place in the bore 7, and the mounting means 17 around the cylindrical skirt 13 by cooperating unidirectionally with the thread 14. It is then very easy to screw the nut 15, for example by means of a pneumatic screwdriver.
  • the nut support 16 can extend parallel to the bodywork element 19 in the form of a housing 34, as shown in Figures 1 to 3; thus, this assembly 10 may include an electrical supply by means of a supply cable 40, with or without connector, electrical means 35, for using the antenna for the operation of both a radio and a radio.
  • the cable 42 is for example intended for the operation of the radiotelephone to the antenna of which it is connected via the connector 242 and another cable via a connector 41 allows the operation of the radio station, the electrical means 35 comprising a duplexer;
  • the nut support 16 can be simple in shape and only be used for mounting an antenna intended for the sole operation of a radio, as shown schematically in Figures 8 and 9 described briefly below; it is also possible to incorporate into said nut support 16 amplification means for this radio antenna supplied with electrical energy by a power cable 40, as shown in the diagram in FIG.
  • the same hollow part 11 comprising the same support 12 and the same pin 9 can be associated with different nut supports 16 for the operation of an antenna for a radio set, with or without amplification, or for a radio and a radio telephone, see for a radio telephone only; of course, it is also possible, whatever the desired configuration, to provide the same base support as described with reference to Figures 1 to 7 using only the (or the corresponding output (s): it is thus possible to configure an installation having a radio station alone, a radio station with an amplifier or else a radio station and a radio telephone with a single antenna thanks to a duplexer; to avoid assembly errors, connectors 41 and 242 can be of different colors, or one can be a male connector while the other is a female connector.
  • the power cable 40 and the connector 41 are placed on one side relative to the assembly 10, while the connector 242 is placed on the opposite side; in a variant not shown, the power cable 40 and the connectors 41 and 242 are all three placed on the same side with respect to the assembly 10.
  • FIGS. 8 and 9 show the variant mentioned above, where only the mounting assembly of the base is shown; elements similar to those described in connection with the variant according to FIGS. 1 to 7 bear the same reference increased by 100 and will therefore not be described further; the variant of FIGS. 8 and 9 being specific for mounting an antenna intended for the sole operation of a radio, the nut support 116 is simpler than the nut support 16 described above; note that the nut support 116 carries a connector 160 for connection of the cable 142 to the actual antenna cable for connection to the radio station.
