Definitions

  • the invention relates to a vehicle antenna with an antenna base that can be mounted on the vehicle body and an antenna rod.
  • Such a vehicle antenna is known from DE-Al-32 05 750.
  • the antenna base of this conventional vehicle antenna is made of a rigid, rigid insulating material. It is attached to the body via a screw connection.
  • the receiver connection cable is also screwed to the antenna base.
  • Such an antenna base construction is cumbersome and complex both in terms of manufacturing and assembly costs. To seal the antenna base against the body part, additional elements for sealing are required, which further increase the effort for assembly.
  • the invention is therefore based on the object of providing a vehicle antenna which is simple in terms of structure, production processes and assembly, has a long service life and is functionally reliable and easy to handle for the user.
  • the object is achieved in that a detachable connector is provided for the electrical connection of the antenna base with a receiver connection cable. This makes mounting the antenna on the body much easier. Replacing the antenna base therefore only requires removing or plugging in the connector part provided on the receiver connection cable without screwing measures. Since the high-frequency cable is not screwed on it is not necessary to hold the antenna base when installing the antenna base.
  • a further simplification of antenna assembly can be achieved with an embodiment in which the connector outer conductor comes into contact with a body part when the connecting cable connector is plugged onto the antenna base. This means that a ground washer and screwing are not required.
  • the connecting cable connector has an elastic, conductive ground sleeve connected to the connecting cable outer conductor, which is pressed onto a body part when the connecting cable connector is plugged onto the antenna base. This results in reliable ground contacting only by plugging in the connector without additional assembly effort.
  • the connecting cable connector has at least one elastic snap-in projection which snaps into the body bore.
  • a secure hold of the connecting cable connector can only be achieved by plugging it onto the antenna base.
  • Either a plurality of locking projections arranged over the circumference of the body bore, or a locking projection extending over the entire circumference can be provided.
  • the at least one locking projection is preferably provided on a plastic cover of the connecting cable connector. The plastic cover thereby protects the connecting cable connector against dirt and water ingress.
  • the at least one latching projection has a latching lever is particularly advantageous. Because of this, it is on easily possible to bend the snap-in projection by hand without a tool and to remove the connecting cable connector from the body bore. The maintenance and assembly effort when changing the antenna or checking the electrical connections is therefore extremely simple.
  • a metal bracket or a trough with a recess or a bore is provided for clipping in the connecting cable connector and / or for making ground contact. Apart from the fact that the metal bracket or the trough gives the connection cable connector a secure hold, a small installation depth for the antenna can be achieved.
  • the antenna base has a contact sleeve for inserting one end of the antenna base contact. In this way, the assembly of the vehicle antenna is further simplified.
  • the contact sleeve preferably has an elastic, inwardly projecting projection which, when the antenna foot contact is inserted, engages in a recess, which can be an annular groove, for example.
  • a body of the antenna base consists of an elastic material and the body of the antenna base can be clipped into a body hole.
  • This measure according to the invention is particularly advantageous in particular because because sealing is guaranteed without additional sealing measures or sealing elements. Bores in the body for attaching vehicle antennas are particularly at risk of corrosion, so that in the conventional installation of vehicle antennas in body bores, complex additional measures for sealing were necessary.
  • an amplifier and / or a coil for antenna extension is preferably provided in the antenna base.
  • the amplifier and / or the coil is or are preferably cast in the elastic material of the antenna base, which results in simple manufacture and the penetration of liquid to the circuit parts is reliably prevented.
  • an antenna base 1 made of an elastic material is fastened to a body panel 2 which has a bore 3.
  • the antenna base 1 has at the lower end a tapered antenna base part 5 which is provided with a bevel 4 on the circumference and which is clipped into the bore 3 of the body panel 2 via the bevel 4.
  • the edge 6 of the bore 3 of the body panel 2 is clipped by the elastic material of the antenna base 1 or the antenna base part 5, so that the antenna base 1 itself the hole 3 of the body panel 2 seals securely.
  • antenna rod 8 In a recess 7 of the antenna base 1 there is an antenna rod 8, the antenna rod base 9 of which has a non-elastic latching part 10 which lies in a recess part 11 of the recess 7 of the antenna base 1 which has a complementary shape.
  • a connector part 12 in the form of a plug contact protrudes into an axial bore of the locking part 10 and forms the electrical connection between the antenna rod 8 and an antenna base connection 13, which in the exemplary embodiment shown comprises an extension coil 14.
  • the lower end of the antenna foot connection 13 projects into a connection base 15 for the receiver connection cable 16.
  • the outer conductor 17 of the receiver connection cable 16 is connected to a conductive element 18, which is pressed in a conventional manner via a screw or nut 19 with its oblique ends for mass contacting the inner surface of the body panel 2.
  • the inner conductor of the receiver connection cable 16 is in electrical contact via the connection with the antenna base connection 13 of the antenna base 1.
  • FIG. 2 shows an embodiment for a detachable plug connector 41 for the electrical connection of the antenna base to the receiver connecting cable 16. Details of FIG. 2 are shown in different representations in FIGS. 3 and 4. The components and elements shown in FIGS. 2 to 4, which correspond to those of FIG. 1, are provided with the same reference numerals as in FIG. 1.
  • the detachable connector 41 which is designed as a latchable cable connection for automatic assembly, comprises a plastic cover 42, a plug contact 43, and an electrically conductive ground sleeve 44. At the edge of the plastic cover 42 are formed obliquely outward, elastic snap-in projections 45, and have a locking lug 46, as best seen in FIG. 6, which shows a special embodiment of the plastic cover 41 with the snap-in projection 45 in an enlarged partial view.
  • FIG. 6 shows a special embodiment of the plastic cover 41 with the snap-in projection 45 in an enlarged partial view.
  • the edge 6 of the bore 3 in the body panel 2 from Material of the antenna base 1 comprises after the antenna base 1 has been clipped into the bore 3 of the body panel 2 using the bevel 4 of the lower antenna base part 5.
  • the lower end of the antenna base connection 13 is inserted into a contact sleeve 46 which is concentrically surrounded at a distance by a shielding sleeve 47 anchored in the material of the antenna base 1.
  • the space between the contact sleeve 46 and the shielding sleeve 47 is filled with the material from which the antenna base 1 is made.
  • an electrically conductive trough or a metal bracket 48 is arranged axially symmetrically to the contact sleeve 46 and is electrically connected to the body panel 2, for example by welding.
  • the electrically conductive trough or the metal bracket 48 have a bore or recess 49 which is concentric with the contact sleeve 46 and into which the connecting cable connector is inserted, so that its plug contact 43 is connected to the inner conductor of the receiver connecting cable 16 in order to connect the antenna.
  • the latching projection 45 engages with its latching lug 46 behind the trough or behind the metal bracket 48, so that the connecting cable connector 41 is held firmly and securely or is locked.
  • the ground sleeve 44 has the shape shown in FIG. 5 as a stamped part.
  • the connecting lug 51 is bent around the outer conductor 17 for contacting, as can be seen most clearly from FIG. 3.
  • the ground sleeve 44 essentially has the shape shown in FIG. 2 in cross section; d. H. it is essentially cup-shaped with an outer diameter selected in such a way that it can be arranged inside the plastic cover 42.
  • the upper ends 53 of the ground sleeve 44 are slightly bent outwards, so that the shielding bushing 47 of the antenna base 1, which - as can best be seen from FIG. 7 - is bent inwards at its end when the connecting cable connector 41 is plugged in slides into the interior of the ground sleeve 44 and thereby presses the edges of the ground sleeve 44 outwards.
  • the side walls of the plastic cover 42 have slots 54 through which the ground claws 55 of the ground sleeve 44 project radially outwards.
  • the connecting cable plug connector 41 When the connecting cable plug connector 41 is pushed onto the shielding bushing 47, this pushes the ground claws 55 outwards due to its appropriately selected diameter.
  • the ground claws 55 come into contact with the edge of the bore 49 in the metal bracket 48 and in this way make a secure ground contact between the outer conductor 17 of the receiver connection cable 16 and between the shielding bushing 47 and the metal bracket 48 or the body panel 2 via the ground sleeve 44 .
  • the snap-in projection 45 has a removal lever 56 projecting outwards. With the aid of this dismantling lever 56, it is possible in a simple manner without any tools, simply by bending the elastic snap-in projection 45 in the radial direction towards the plastic cover 42 and thus removing the entire connector 41 from the body panel.
  • FIG. 7 A special embodiment of a contact sleeve 46 and the end of the antenna base connection 13 is shown in FIG. 7.
  • an antenna foot contact 59 has a concave groove 57, into which a nose 58 engages when the antenna foot contact 59 is inserted into the contact sleeve 46 and which is bent inward and elastic from the slotted contact sleeve 46. In this way, the antenna foot contact 59 is locked in a simple manner in the contact sleeve 46.
