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.
  • the antenna rod is connected to the antenna base by a screw connection.
  • handling is also cumbersome and complicated for the user.
  • the rod thread with which the antenna rod is attached to the antenna base can become dirty or damaged, so that the mountability is impaired and the contact resistance is increased.
  • the antenna rod base or a region of the antenna rod must additionally be cast in an elastic material, which further increases the manufacturing outlay.
  • 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 for User is easy to use.
  • a body of the antenna base consists of an elastic material, and the antenna rod is mechanically and electrically detachably connected to the antenna base with a snap connection.
  • the antenna rod it is possible to releasably connect the antenna rod to the antenna base without a screw connection, so that a very simple antenna structure with simple assembly results.
  • the elastic antenna area is integrated in the antenna base, so that additional manufacturing processes for the creation of the elastic antenna area, such as for example casting a part of the antenna rod into an elastic plastic, are unnecessary.
  • the snap-in connection according to the invention between the antenna rod and the antenna base it is possible to change the antenna rod quickly or to remove the antenna rod, for example, before driving through a washing system without installation tools. This is ensured by the fact that, in contrast to conventional rod antennas, there is no screw connection between the antenna base and the antenna rod. As a result, there is also no risk that the connection between the antenna rod and antenna base can be damaged, or that the functioning of the antenna suffers, for example, from contamination. This significantly extends the life of the vehicle antenna.
  • the body of the antenna base is made of polyurethane. This material is similar to rubber and very elastic.
  • a plug connector is provided for the releasable electrical connection of the antenna base and the antenna rod. This ensures a secure, detachable electrical connection without screws or other tools.
  • the antenna base body preferably has a recess for the pluggable reception of an antenna rod base. This makes it possible to insert the antenna rod base into the antenna base body in order in this way to connect the antenna base body and the antenna rod in a mechanically and electrically reliable detachable manner.
  • the outside diameter of the antenna rod base is larger than the inside diameter of the recess of the antenna base body.
  • the inside diameter of the antenna base which is made of elastic material, expands and encloses the antenna rod base tightly and securely. This gives the antenna rod a secure hold in the antenna base.
  • a connector part is integrated in the antenna base body.
  • the metallic connector part is preferably cast in the antenna base body and protected from the outside.
  • the recess of the antenna base body has a receiving part, into which a contact pin of the connector part protrudes axially symmetrically.
  • the receiving part preferably widens conically outwards. This results in an insertion bevel that ensures a centered insertion of the antenna rod foot into the recess.
  • the antenna base body preferably has an elastic latching element protruding into the recess.
  • the snap element can be an independent part that is cast in the elastic material of the antenna base, it is advantageous with regard to a simplified production method if the latching element is formed in one piece with the antenna base body.
  • a further advantageous embodiment of the invention in this context is to design the latching element as a flexible latching lip.
  • the lip is not squeezed between the latching part and the associated wall when inserted.
  • the flexible locking lip rather yields when the locking part is pressed in and when the antenna base is pulled out, and then returns to the desired position. Due to the dimension of the lip and the choice of the antenna base body material, the force for pushing and pulling the antenna rod base into or out of the antenna base body can be selected.
  • the flexible locking lip ensures that the antenna rod is securely inserted, locked and aligned.
  • An advantageous embodiment of the invention consists in that the antenna rod base has an essentially non-elastic latching part with a shape which is essentially complementary to the receiving part of the antenna base body. This ensures a secure, axially symmetrical insertion of the antenna rod into the antenna base with good alignment and a firm fit.
  • the antenna rod base preferably has a taper into which the latching element of the antenna base body releasably latches when the antenna rod is inserted.
  • the taper can also be designed as a groove, or form a shoulder that ensures a lock and still allows the antenna rod to be pulled out.
  • the elastic snap-in element projecting into the recess of the antenna base body securely engages behind the shoulder or an edge of the groove that is created, so that a secure hold of the antenna rod in the antenna base body is ensured.
  • the antenna rod base preferably has a round contact electrically connected to the antenna or the antenna core, the axial bore of which receives the contact pin of the antenna base which projects into the receiving part when the antenna rod is inserted. It is therefore easy to pull out or insert the antenna rod into the antenna base without tools.
  • the round contact is preferably a spring sleeve, which enables reliable, releasable contact.
  • the round contact is slotted.
  • the spring sleeve it is particularly advantageous to design the spring sleeve as a basket spring. This ensures permanent contact and the contact pin of the antenna base is easy to insert into the round contact.
  • An amplifier and / or a coil for antenna extension is provided in the antenna base for high-frequency adaptation of the antenna.
  • 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.
  • a particularly advantageous embodiment of the invention is that the elastic body of the antenna base in a body hole can be clipped on. This makes it possible to attach the antenna base to the body in the simplest way without additional tools. This embodiment is particularly advantageous in particular because sealing is guaranteed without additional sealing measures or sealing elements.
  • an antenna base 1 made of an elastic material is attached 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 seals the bore 3 of the body panel 2 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 with a screw or nut 19 with its oblique ends for mass contact to 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 the connection area shown in FIG. 1 between the antenna base 1 and the antenna rod 8 in an enlarged representation. Parts that correspond to those of FIG. 1 are given the same reference numerals in FIG. 2 as in FIG. 1 and are not explained again.
  • the recess 7 of the antenna base 1 is divided in the illustrated embodiment into the conical recess part 11, a cylindrical recess part 21 with a larger diameter and a cylindrical recess part 22 with a smaller diameter. Between the conical recess part 11 and the cylindrical recess part 21 with a larger diameter there is a latching element 23 which protrudes in a ring into the recess 7 of the antenna base 1.
  • the snap element 23 is formed in one piece with the antenna base 1 in the exemplary embodiment shown and thus consists of the elastic material of the antenna base 1, for example of polyurethane.
  • the elastic latching element 23 is shaped in the form of a flexible lip.
  • the connector part 12 protrudes axially symmetrically into the conical recess part 11 of the antenna base 1 in the form of a contact pin.
  • the latching part 10 is fastened to the antenna rod base 9 of the antenna rod 8, in which a round contact 24 is arranged axially symmetrically as a connector part for the antenna rod 8.
  • the round contact 24 is electrically connected to a sleeve 25, which is connected, for example via a soldered connection 26, to a conductive core 27 of a glass fiber antenna rod 8.
  • the conical locking part 10 of the antenna rod base 9 slides into the recess, the recess part 22 having a smaller diameter being widened by the conical locking part 10.
  • the locking part 10 then slides further through the cylindrical recess part 21 with a larger diameter, which corresponds approximately to the largest diameter of the conical locking part 10, and displaces or bends the elastic locking element 23 so that the locking part 10 of the antenna rod base 9, from the insertion slope of the conically tapered recess part 11 guided axially symmetrically, comes to rest in the recess part 11.
  • the connector part 12 of the antenna base 1 slides through an opening 28 into the round contact 24 and establishes the electrical connection between the antenna base 1 and the antenna rod 8.
  • the elastic latching element 23 which is a flexible lip in the example shown, slides inward again behind a shoulder 29 formed by the conical latching part 10 and locks the antenna rod base 9 and thus the antenna rod 8 in this position.
  • the elastic latching element 23 designed as a flexible lip is bent upward by the shoulder 29 of the latching part 10 and the latching part 10 can slide past it outwards.
  • the elastic locking element 23 Due to the insertion bevel formed by the conical locking part 10, the elastic locking element 23 is not squeezed between the locking part 10 and the outer wall of the recess part 7, the locking element 23 can rather evade both when the locking part 10 is pressed and when it is pulled out, and then back into the Decrease target position.
  • the push-in and pull-out force can be selected by appropriate choice of the material from which the snap-in element 23 is made and / or by the corresponding shape and dimensions of the snap-in element 23.
  • the elastic locking element 23 is designed in the embodiment shown in FIG. 3 so that it is not designed as a uniformly thick flexible lip, as in the embodiment shown in FIG. 2, but with a bevel 31, so that the inside diameter of the locking element 23 of gradually decreasing from the outside to the inside.
  • the latching part 10 When pushed in or pulled out The latching part 10 therefore does not bend over in the latching element 23 shown in FIG. 3, but merely displaces it outwards.
  • FIG. 4 shows an alternative embodiment of the antenna rod 8 in the form of a stainless steel antenna. Elements and parts which correspond to those of the previous figures are again provided with the same reference symbols in FIG. 4 as in the previous figures.
  • the round contact 24 is elongated as a sleeve in which the end of the steel rod 8 facing away from the connecting end of the latching part 10 is inserted.
  • the round contact 24 is preferably a spring sleeve, in particular a spring cage.
  • the electrical contact between the antenna rod 8 and antenna base 1 can be guaranteed even better and safer.
