Definitions

  • the invention relates to a housing antenna arrangement according to the preamble of claim 1.
  • a housing antenna arrangement is proposed, the realization of which is based on a pressure contact between the metal the antenna housing and the associated electronic circuit for operating the antenna housing is based as a housing antenna using resilient elements.
  • the housing antenna arrangement according to the invention enables the cost and time-saving automatic mass production of electrical or electronic devices with such a housing antenna arrangement.
  • the housing antenna arrangement according to the invention allows non-destructive disassembly of relevant devices, since no structural connection such as a direct soldering or gluing is present.
  • housing antenna arrangement according to the invention can be used in the case of devices in which, for design reasons, no visible screw connections are permitted.
  • the fixation of the resilient elements either on the metallic antenna housing or on the said carrier can be accomplished, for example, by soldering.
  • the resilient elements are fixed on said carrier, in a particularly advantageous embodiment of the invention find the metallic antenna housing at locations where the resilient elements contact the antenna housing resiliently provided independent contact elements that are particularly good electrical conductivity.
  • a particularly good electrically conductive connection between the antenna housing and the said electronic circuit is important for a particularly well-functioning housing antenna.
  • the resilient contact elements are designed as SMD contact springs. They are inexpensive and allow a small design of relevant devices.
  • the electrical connection distance of points of contact with the metallic antenna housing and the electronic circuit is chosen as short as possible. This avoids the introduction of unwanted inductances.

  • Embodiment of Figure 2 and Figure 6 shows an electrical assembly and an antenna housing respectively according to the invention for the exemplary embodiment of Figure 2, wherein the electrical assembly is mounted in the antenna housing.
  • like parts are given the same reference numerals in the figures.
  • FIG. 1 shows a first housing antenna arrangement 1 and FIG. 2 shows a second housing antenna arrangement 2.
  • Both housing antenna arrangements 1 and 2 have a metallic antenna housing 3 and an electronic circuit 4 for operating the antenna housing 3 as a housing antenna.
  • the electronic circuit 4 is mounted on a support 5.
  • the carrier 5 is a printed circuit board in detail.
  • the electronic circuit 4 and the carrier 5 or the printed circuit board together form an electrical component.
  • an electrical assembly 5 further circuits are mounted on the carrier, but in the present context play no role and omitted for simplicity in the present embodiments and are not otherwise mentioned.
  • the electrical assembly and thus in particular also the electronic circuit 4 are placed inside the antenna housing 3.
  • the carrier 5 has connection lines for the supply and discharge lines of electrical signals from and to the electronic circuit 4, which are likewise not shown in greater detail in the figures.

  • FIGS. 3 to 6 the elements explained in connection with FIGS. 1 and 2 and provided with reference numerals can at least partly be seen again from another perspective. It should be mentioned in particular in connection with FIG. 6 that the separate contact elements 8 present there in the antenna housing 3, with which the covertly shown resilient elements 7 contact resiliently from the carrier 5, are not explicitly indicated. The resilient elements 7 are therefore shown concealed in FIG. 6 because the carrier 5 is mounted over the antenna housing 3 in the head.
