Definitions

  • the invention relates to a connector antenna, in particular for motor vehicles, which has a spout made of elastomeric material, which in its lower Area with a circumferential locking groove for receiving a peripheral edge of a Opening of a surface supporting the antenna is provided and in the an antenna element the antenna is receivable.
  • Such a plug-in antenna is from DE-40 37 712 C2 and from DE-40 05 029 C2 known.
  • DE 40 37 712 C2 also discloses one capacitive ground coupling of the antenna.
  • the disadvantage of this is that the assembly process the antenna in a body hole of a body panel Motor vehicle not by a single mechanic from the interior of this Motor vehicle is feasible.
  • the spout in its lower Front face has an axially directed, annular recess into which the lockable locking ring can be inserted into the lower end face of the grommet is.
  • the measures according to the invention advantageously achieve that now the assembly of the attachable antenna according to the invention can be carried out without the mechanic having to force the Support of a second person to operate or during the assembly process the interior of the body of the antenna with the invention to leave equipped motor vehicle.
  • An advantageous development of the invention provides that the locking ring through a metallic earth ring can be locked on the spout, which is advantageous Way simultaneously the antenna element of the antenna according to the invention capacitively coupled to ground.
  • This capacitive ground connection of the antenna on the body panel has the advantage that this makes it particularly simple and way without damaging the body panel or one that covers it Paint layer a good ground connection can be made.
  • a shield one the antenna element of the antenna according to the invention with a Corresponding transmitting or receiving device connecting high-frequency cable by means of a wedge made of metal or plastic in the antenna element is attachable. This procedure advantageously and Way achieved that the RF cable without soldering or crimping at the same time Strain relief can be attached particularly easily.
  • Another advantageous development of the invention provides that the antenna element surrounding and in the spout of the antenna according to the invention insertable insulation body with coil tracks running on its outer surface, the ends of which penetrate radially into the interior of this insulating body Pass holes, is provided.
  • This measure according to the invention enables the production of a blocking circuit in an advantageous manner simultaneous coil attachment to the insulation body without being forced is to solder or close the wire forming the coil to the antenna element crimp.
  • FIG. 1 to 6 of a linkable Antenna which in particular as a combination antenna for the D or E mobile radio network is suitable, is basically divided into an elastomeric material existing spout 1, in a corresponding hole 2 'of a body panel 2 can be used.
  • an antenna element 20 which below is described in more detail.
  • the spout 1 also - in still more known per se Way - in its lower area a radially directed locking groove 3rd on, in the inserted state of the insertable antenna described the peripheral edge of the bore 2 'of the body panel 2 can be received.
  • the spout has a radial one Vorrastrille 4, which seen in the insertion direction X of the antenna in front of formed as a circumferential groove locking groove 3.
  • This pre-groove 4 allows it in an advantageous manner, the spout 1 in a first assembly step Provisional assembly process in the body bore 2 '' of the body panel 2 to lock, then - as shown in Figure 2 - by means of an appropriate Auxiliary tool H (see Fig. 2) or if necessary - but not is preferred - by a corresponding pull from the outside in FIG.
  • the ring slot 11 preferably also has one in the region of the locking groove 3 Cavity 12, which when pressing the auxiliary tool H into the ring slot 11 is stretched and also the wall thickness of the spout 1 in this area even further reduced, which advantageously due to the even easier elastic deformability of the spout 1 the assembly process the antenna described is further facilitated.
  • the mass ring 14 is not only used for mechanical fastening of the antenna in the body bore 2 'of the body panel 2. Rather, it is made of stainless steel Masserings 14 achieved a capacitive coupling of the antenna to ground. For this is between the electrically conductive body panel 3 and at least one Part of the annular surface 14 'of the earth ring 14 arranged a dielectric, which preferably as a dielectric adhesive film, as a coating or as a varnish, etc. on the body panel 2 and / or the annular surface 14 'of the mass ring 14 is. Furthermore, the ground ring 14 has a capacitive ground connection fan-like spring segments 15a-15h in an annular arrangement, which also are preferably made of stainless steel.
  • FIGS. 5 and 6 now show details of the design of the antenna element 20 shown.
  • the fixation of one best seen in FIG. 5 is advantageous the antenna described with a corresponding transceiver connecting high-frequency cable 30.
  • a shield 31 of the HF cable 30 by means of a metal or plastic Wedge 32 is pressed to a mass part 21 of the antenna element 20.
  • a Such an approach not only has the advantage that a safe ground contact and - for a metallic part - almost no change in impedance occurs at this point. Rather, the construction described also a strain relief for the RF cable 30 is formed.
  • Another advantage is that the shield 31 of the RF cable 30 is particularly simple and without Crimping can be connected to the ground part 21 of the antenna element 20 can.
  • FIG. 6 shows a particularly simple way of producing and Mounting a blocking circuit on the antenna element 20 of the described Antenna shown.
  • a helical serving as a coil track extending groove 25 arranged on an upper part 20a of antenna element 20 surrounding insulation body 23 .
  • the helical groove 25 goes to hers both ends in a radially extending bore 26, 26 ', which of the outside of the insulation body 23 up to which the antenna element 20 receiving interior 23 'is sufficient.
  • this blocking circuit is in a first blocking circuit assembly step forming the coil of the blocking circuit Wire 27 through the upper bore 26 so far into the interior 23 'of the Insulating 23 inserted that a slight insertion of an upper Radiator 20a of the antenna element 20 in the interior 23 'of the insulating body 23 a clamping of the wire 27 between the outer surface 20 'of the antenna element 20 and the inner surface 23a of the insulating body 23 is reached and such a reliable contact between the wire 27 and the antenna element 20 is manufactured.
  • the wire 27 is wound along the helical groove 25 forming the coil path and thereafter cut to length by the at the bottom of the Coil path located radially into the interior 23 'of the one forming the coil core Insulating body 23 entering further opening 26 'and inserted through Pushing in another radiator element 20b of the antenna element 20 to become.
  • the antenna described is not only characterized in that it can be manufactured particularly easily. Much more Furthermore, the construction described enables the antenna from a single person from the interior of a vehicle body, without assistance an assistant, can be assembled.
