  • the connector further has a tightly formed pin with an external thread, so that both the guide pin and the connector part must be screwed separately into the tool part and removed from there again, resulting in an increased workload.
  • the antenna coil is inserted in a shoulder of the bore of the connection part. This is also unfavorable because the attachment between these two Due to the massive design of the connection part, components can ultimately only be made by soldering.
  • the invention is therefore based on the object to avoid these disadvantages and to provide a rod antenna and a method for the production, in which the reception of the antenna is improved, and the cost of production can be reduced.
  • the receiving region of the connecting part is formed as a sleeve in which the antenna coil is fixed. Due to the configuration of the receiving region of the connection part as a sleeve, the antenna coil can be well guided and it can be provided any attachment of the antenna coil.
  • the antenna coil can, for. B. by inserting and stamping the sleeve, by inserting and soldering or by screwing the antenna coil into the sleeve. It is not absolutely necessary that an internal thread for the antenna coil is provided in the sleeve. It is sufficient that the dimensions of the sleeve and the antenna coil are coordinated so that the outer circumference of the antenna coil is screwed under tension in the sleeve.
  • the antenna coil is designed as a helical spring made of spring steel, wherein the conductivity for the electrical RF function can be improved by copper plating the surface of the coil spring.
  • the sleeve of the connection region is advantageously carried out so long that the high-frequency telephone function of the rod antenna can be realized with this region in addition to the pure attachment function for the antenna coil.
  • the AM / FM function is realized by the part of the coil spring projecting freely from the sleeve. Ideally, this can be dispensed with a coil for decoupling the frequency ranges.
  • a suitable coil will be provided to transmit the high-frequency telephone function Inserted connection part on the antenna coil or the coil spring and connected in this position with the sleeve and coil spring, preferably soldered, is.
  • the coil can also be designed and inserted between the connection part and the antenna coil, preferably with approximately the same diameter as the antenna coil. In particular, when using the antenna coil as a spiral spring this can have over its length areas with different slopes in order to optimize the electrical function of the antenna coil and / or minimize the Materialaufvvand.
  • connection part is advantageously made of brass and nickel-plated to make good contact with the antenna coil and possibly the coil and the antenna base.
  • connection part and / or the sleeve is produced by means of a forming process, in particular extrusion, embossing or rolling.
  • connection part preferably has a known central opening.
  • this opening in which the sleeve facing away from the area, an internal thread can be provided, with which the connection part can be screwed with a threaded pins of the antenna base.
  • a threaded pin can also be screwed into the internal thread of the connection part and screwed to the antenna base.
  • the connection part may also have a fitting path along the central opening, in particular in the region facing away from the sleeve, in which a threaded pin is pressed, which then serves as a screw for connection to the antenna base.
  • the proposed internal thread in the connecting part can receive, at least during manufacture, the external thread of a mandrel which projects through the opening of the connecting part and at least part of an opening in the antenna helix, wherein the protruding part of the external thread of the mandrel can be screwed into the tool part.
  • the mandrel may advantageously be made slightly tapered towards its free end in order to achieve easy removal after encapsulation with encasing material.
  • a material is proposed, which remains elastic after cooling and consists of thermoplastic material, for. B. Santoprene.
  • the central opening in the connecting part can have a sealing region in the direction of the sleeve following the fitting path or the internal thread, which, together with the cross section of the mandrel, is designed such that no covering material passes through this sealing region during production.
  • the proposed features overall a very simple construction of the rod antenna is possible because they can be made with suitable strength of the coil spring without a mandrel. It is also a simple production of the rod antenna possible, since it can be produced without further aids, even solderless. It is also an optimal design possible, with no retaining holes and seams in the sheath material are needed. With only one variant, an AM / FM and a telephone function is possible. For the rod antenna, only one basic version is required for the antenna base with female or male threaded pin. It can be achieved any bending stiffness and good recovery behavior.
  • the antenna coil is fixed to the sleeve of the connection part, that the connection part is fastened to the tool part, that the tool part with a one- or multi-part tool counterpart, with its inner shape outer contour of the rod antenna corresponds, connected is that the sheath material is injected into the tool and that the rod antenna is formed.
  • a mandrel in the central opening of the connection part and in the antenna coil or a part of the antenna coil can be inserted and connected to the connector, in which case the remaining threaded portion of the mandrel can be used simultaneously for securing the mandrel and the connector to the tool part.
  • a counter-extension pin arranged in extension of the mandrel can be provided on the tool counterpart, which is fixed with the mandrel before the injection of the casing material and that the counter-holding pin is retracted in the Nachbuchphase of the casing material for closing the opening of the counter-holding pin.
  • a fixation of the retaining pin on the mandrel is possible in that the retaining pin engages in an end-side recess of the mandrel.
  • 1 denotes a connection part, on which a designated 2 sleeve is formed.
  • a designated 3 spiral spring is used, which is slightly pressed in the sleeve.
  • the connecting part 1 has on the end facing away from the sleeve usually an internal thread 4, with which the antenna rod can be connected to an antenna foot, not shown attached to the vehicle.
  • the antenna base has mating thread mating parts to the connecting part 1, which can be designed both in the manner of a nut and in the manner of a screw.
  • the internal thread 4 of the connecting part 1 can, as shown in Figure 5, record a threaded pin 5, which then protrudes from the connector part 1 and can be screwed to the antenna.
  • a pin be formed, which carries an external thread.
  • the AM / FM function is usually taken over by the protruding from the sleeve 2 coil spring 3.
  • the sleeve 2 in turn can also take over the high-frequency telephone function of the rod antenna in addition to its attachment function. If this is not sufficient, then, as shown in Figures 2 and 8, following the sleeve 2 with the same diameter as the coil spring 3 or around the coil spring, arranged around a coil 6 and electrically connected to the sleeve.
  • the connecting part 1, the coil spring 3 and possibly the coil 6 are attached as a finished component to a tool part 7 ( Figures 3 and 8).
  • a tool counterpart part 8 is mounted and connected to the tool part 7.
  • the cavity formed by the connection part 1, the coil spring 3 and possibly the coil 6 and the inner shape of the tool counterpart part 8 and the tool part 7 is filled with a covering material 9, wherein the covering material is injected. It is preferably made of thermoplastic material which remains elastic after cooling, but assumes a solid substance.
  • a designated 10 mandrel is pushed through the central opening in the connection part 1 and in the cavity of the coil spring 3 and connected to the tool part 7, preferably screwed before applying the sheath material, so that this mandrel 10 significantly improves the stability of the coil spring 3.
  • the mandrel 10 has at its end a threaded part which can be screwed into the internal thread 4 of the connection part 1 and into the tool part 7.
  • the spiral spring 3 can have regions with different pitches over its length in order to optimize the electrical function of the rod antenna.
  • the connector 1 is first screwed onto the mandrel, then, if the phone function is intended, the coil 6 is pushed and then applied the coil spring 3 and coil 6 and the coil spring 3 soldered to the connector part 1. If it is a soft coil spring 3, it can be slipped over the coil spring 3, the coil 6 and the sleeve 2 of the connection part 1, a shrink tube and shrunk by heating and thus tensioned to give the components a higher stability.
  • the mandrel 10 has according to Figure 8 at its free end on a deflection, which can be brought into operative connection with a counter-holding pin 11, so that the end of the mandrel 10 can be further stabilized during the injection of the casing material. Then, when the sheath material is still under pressure, immediately after injection, the detent pin 11 is displaced away from the mandrel 10 so that the opening in the sheath material closes.
