Definitions

  • the invention relates to an antenna, in particular for motor vehicles, having an antenna base which is fastened to the motor vehicle and has a threaded element, which is electrically connected to electrical / electronic devices in the motor vehicle, and with an antenna rod, which has a threaded counter element is electrically connected to a receiving coil, wherein the threaded counter-element and the receiving spiral are at least partially disposed in an elastic Umspritzmaterial.
  • a generic antenna is known from US 6,271, 804 B1. This document describes both the attachment of the antenna to the motor vehicle, as well as the antenna element and a manufacturing method.
  • a receiving spiral is provided which is fastened at its end adjacent to the vehicle on a connecting piece serving as a threaded counterpart element.
  • the receiving coil is at least adjacent to the connector, wound more tightly to produce a better grip on the connector.
  • an embossing or another fastening of the receiving spiral must be made to the connecting piece.
  • the connector which has several paragraphs and a threaded piece, is expensive to manufacture. The preparation of such an antenna is a total of consuming and expensive, both with respect to the processing of the connector and the special shape of the receiving coil and its attachment to the connector. Furthermore, the assembly is labor-intensive and therefore expensive also from the workload.
  • the invention is therefore based on the object to provide an antenna, in particular an antenna rod, is available, which is simple and inexpensive to manufacture and also has good signal properties.
  • the object of the invention is achieved in that the threaded counter-element is designed as a threaded spring and is embedded in Umspritzmaterial.
  • a threaded spring is considerably simpler and less expensive than the prior art connector, while still allowing easy connection to the receiving coil and the antenna socket.
  • the threaded spring has at least one end of a Verwarêts Kunststoff projecting into the Umspritzmaterial. This creates a close connection of the encapsulation material with the threaded spring, so that it finds a secure fit in the encapsulation material.
  • the threaded spring may consist of a wire having a circular or a square, in particular diamond-shaped cross-section. If a wire with a round, circular cross-section is used, the thread element must be adapted to this shape. But if a quadrangular, in particular diamond-shaped cross-section is selected, then the threaded spring can be designed to match a threaded element which is designed as a nut or as a screw with a metric thread. If the threaded spring is used as a screw, it is proposed that the end of the threaded spring projects beyond the antenna rod and can be screwed to a threaded element of the antenna base designed as a threaded nut is.
  • the shape and configuration of the threaded spring offers the possibility of providing a radial and / or axial deformation in order to produce a higher screwing and in particular a higher release torque relative to the screw or nut of the threaded element, so that the antenna rod is securely fastened to the antenna socket.
  • the threaded spring also allows a good attachment of the receiving spiral, wherein it is proposed that the receiving spiral is screwed with radial bias on or in the threaded spring. This results in a good attachment and electrical connection of the receiving coil with the threaded spring, which is increased even if the receiving spiral is so encapsulated from the outside or injected from the inside that it is permanently fixed firmly in the spiral groove of the threaded spring.
  • a good support of the threaded spring and the receiving spiral results from the fact that the threaded spring and / or the receiving spiral at least partially ejected in the interior with an elastic plastic material before encapsulation are or filled with an elastic support rod.
  • the receiving coil can also be arranged on a guide rod and preferably fixed there, wherein the guide rod is fixed in or on the end region of the threaded force fit, eg by means of press fit.
  • the receiving spiral can be clamped between the end region of the threaded spring and the guide rod, resulting in a good electrical contact and a good attachment of the thread spiral.
  • the Umspritzwerkmaschine has a centering mandrel for fixing the threaded spring, the guide sleeve and the receiving spiral to each other, so that during the injection process no displacement of the parts to each other and a lack of contact or a lack of attachment occurs.
  • the threaded spring is, as already mentioned, able to absorb a large part of the deflections that an antenna rod is to allow.
  • the threaded spring is formed by selecting its length and / or the wire thickness and / or the wire material so that the flexibility of the antenna rod is mainly in the area of the thread spring.

  • the antenna base 2 has a preferably made of plastic base housing 3, in which a threaded element denoted by 4 is embedded, which is formed in Figures 1, 2 and 4 as a screw, while it is designed in Figure 3 as a mother.
  • the antenna rod 1 has overmolded material 5, whose outer shape, starting from the antenna base 2, is tapered.
  • a support or guide rod designated by 6 is arranged within the encapsulation material 5, around which a receiving spiral designated by 7 is arranged.
  • the support or guide rod has a shoulder with which it is non-positively inserted in a threaded spring 8.
  • the heel of the support or guide rod 6 may have a thread with which it can be screwed into the threaded spring 8.
  • the threaded spring 8 is wound so that the wire of the threaded spring 8 is disposed adjacent to each other.
  • the cross section of the wire of the threaded spring 8 is designed trapezoidal, so that the threaded spring can serve depending on the design as a screw or nut and indeed so that it corresponds to the metric dimensions of threads.
  • the receiving spiral 7 is, as shown in Figures 1 to 3, in its threaded spring 8 facing area wound on this, so that there is a good electrical and mechanical connection of the receiving spiral 7 with the threaded spring 8.
  • the end of the threaded spring facing the antenna base is hook-shaped and embedded in the encapsulation material 5, resulting in a good hold of the threaded spring 8 in the encapsulation material 5, in particular for rotational forces.
  • the opposite end of the threaded spring 8 has an extension which is also embedded in the encapsulation material 5.
  • a guide sleeve 10 is provided around the receiving spiral 7, at least in the end region, which surrounds an extension of a support rod or guide rod 6, which is inserted into the threaded spring 8 with an extension.
  • Reference numeral 11 denotes the bent or angled ends of the threaded spring eighth
  • the encapsulation material 5 or the antenna rod 1 has annular sealing lips on the end facing the antenna base 2 in order to prevent dirt and moisture from penetrating between the antenna rod 1 and the antenna base 2.
