Definitions
- the invention relates to an antenna for automobiles with the features specified in the preamble of claim 1.
- Such an antenna is commercially available. It has a foot section with an obliquely upward-pointing rod-shaped radiator for radio reception. Means for fastening the foot part on the roof of the body of an automobile are provided on the underside of the foot part.
- the bodywork has a bore into which a short extension provided on the underside of the foot part is inserted.
- a high-frequency line starting from the lower end of the radiator also ends in the known antenna.
- an angle plug is pushed onto the extension from below and the body panel is clamped between the underside of the foot section and the angle plug.
- the typical frequency ranges are: 70 to 110 MHz in the FM range, 450 to 465 MHz for mobile phones in the C network, 890 to 960 MHz for mobile phones in the D network, 1780 to 1920 MHz for mobile phones in the E network, 1570 to 580 MHz for GPS antennas)
- the present invention has for its object to provide an easy to install, sensitive in different frequency ranges or arrangement of antennas that have a common base from which one or more, in particular up to three high-frequency lines for different frequency ranges emerge.
- These high-frequency lines are said to be able to be passed through one and the same hole, which is also used to fasten the antenna to the automobile, and then to be guided along the underside of the body panel, so that the antenna or arrangement of antennas is attached to the roof of the automobile and the high-frequency cables can be laid between the body panel and the interior roof lining (headlining) without having to change the headlining and without being visible on the headlining.
- the antenna foot part from which one, two or three high-frequency lines can lead out, is to the diameter of the same hole in the body panel is specified, can be attached. In a specific application, there is a requirement to make this possible on a 10 mm diameter bore. It should also be possible to provide on the high-frequency lines emerging from the foot part connectors or couplers of connectors that are mounted on the high-frequency lines before the foot part is mounted on the roof of the automobile on the body, so that the RF lines at Installation of the antenna base on the body can be connected immediately to the ends of further high-frequency lines that are installed in the interior of the vehicle and provided near the hole in the body panel, which are already provided with matching couplers or plugs.
- the antenna is easy to install. First of all, the high-frequency lines emerging from the foot part through the inner sleeve, which may already be provided with plugs or couplers, are pushed one after the other through the hole in the body, which is expediently a circular hole. Then the extension designed as a longitudinally protected sleeve is inserted into the hole and the base part of the antenna is placed on the body panel.
- Antenna attached to the body part of the automobile.
- the inner and outer sleeves can therefore be of such a small diameter that, although they can accommodate all of the cables, it would not be possible to push all the cables provided with couplers or plugs through the outer sleeve.
- plugs or couplers can be installed on the cables leading out of the foot section before the foot section is attached to the body.
- the outer sleeve holds the cables in their bent position and, in conjunction with the clamping devices, also ensures that the antenna is firmly seated on the body.
- ⁇ Thanks to the intended mounting and routing of the high-frequency lines emerging from the foot section, these do not exert any pressure on the headlining when the antenna is mounted on the roof of an automobile, so that they do not become apparent in it.
- the type of attachment is suitable for base parts of antennas from which only one cable leads out, as well as for base parts from which several cables lead out.
- the type of attachment is suitable for one to three high-frequency cables even if there is a hole in the body of only 10 mm in diameter.
- the antenna can be easily dismantled at any time.
- the invention can be applied to an antenna whose radiator is designed only for radio reception.
- the invention is preferably applied to multi-range antennas, in particular to antennas, the radiator of which is a combination radiator for two frequency ranges and in the foot part of which there is a channel from which two high-frequency lines for signals with frequencies in the two frequency ranges start.
- the inner sleeve can be provided with an external thread and a nut matching the external thread can be provided for attaching the outer sleeve to the inner sleeve, by tightening the outer sleeve against the underside of the body panel is pressed. It is more advantageous to provide the inner sleeve with an internal thread and to attach the outer sleeve to the inner sleeve by means of a screw turned into the internal thread, the head of the screw pressing the sleeve against the underside of the body panel. It is particularly advantageous if the screw is captively and captively caught at the lower end of the outer sleeve. This makes it much easier to attach the outer sleeve to the underside of the body panel, because the screw and the sleeve are connected and cannot be lost individually.
- a sliding washer can be provided between the lower end of the outer sleeve and the head of the screw or between the lower end of the outer sleeve and the nut.
- a metallic ring provided with tapered projections is preferably provided between the upper end of the outer sleeve and the base part, the projections of which are pressed against the underside of the body panel in the installed position. Ground contact rings that perform this task are known in automobile antennas.
- the ring with the tapering projections is an integral part of the outer sleeve, be it that the ring is welded or clamped to the sleeve, be it that the outer sleeve is at its upper end - De is formed with a flange as an integral part of the sleeve, which has pointed projections directed towards the body panel. If the ground contact ring is part of the outer sleeve, it cannot be lost during assembly, so that assembly is indeed child's play.
- the high-frequency cables running out of the side of the slots can ensure that the slots in the two sleeves overlap each other.
- This is particularly easy using a tongue and groove, and from the point of view of the anti-rotation device it is in principle irrelevant whether the groove in the inner sleeve and the tongue in the outer sleeve or the groove in the outer sleeve and the tongue on the inner one Sleeve is provided.
- the groove is in the inner sleeve and the tongue is on the inside of the outer sleeve, because in this way the inner sleeve can best be fitted into a predetermined hole in the body panel.
- two tongue and groove pairs are provided in a non-diagonal arrangement. This combines optimal security against rotation with a clear definition of the orientation of the outer sleeve on the inner sleeve.
- Embodiments of the invention are shown in the accompanying drawings. The same or corresponding parts are denoted in the exemplary embodiments with the same reference numerals.
- FIG. 1 is a vertical section (longitudinal section) through an antenna according to the invention in the installed position,
- FIGS. 2-4 show, in a longitudinal section through the extension of the base part of the antenna, three successive phases in the assembly of the base part on a body panel,
- FIG. 5 shows a perspective view of the base part of a modified antenna with the outer sleeve removed
- FIG. 6 shows an enlarged perspective illustration of the foot part from FIG. 5 with the outer sleeve removed and bent high-frequency lines
- Figure 7 shows in a representation corresponding to Figure 6, the foot part with laterally led out high-frequency lines and with the outer sleeve attached to the inner sleeve.
- the antenna shown in Figure 1 has a foot part 1, which has a base plate 2 made of metal and a hood 3 made of plastic, into which the base plate 2 is inserted so that the edge of the hood 3 protrudes slightly downwards over the base plate 2 .
- the contour of the edge of the hood 3 is adapted to the contour of the body panel 4 on which the antenna is to be attached, so that in the installed position of the antenna the edge of the hood 3 lies on the body panel from which the base plate 2 has a little distance .
- a first elastomeric seal 5 is provided on the underside of the base plate 2, which is supported on the underside of the base plate 2 and bears against the edge of the hood 3 in a relaxed state over the edge of the hood 3 protrudes and is compressed when the foot part 1 is fastened on the body panel 4.
- an arrangement 7 comprising a GPS antenna and an associated amplifier
- an arrangement 8 comprising an amplifier and a crossover for signals which come from a rod-shaped combination radiator 9 , which is used to receive radio signals and signals from a telephone network.
- the combination radiator 9 is provided at its lower end with a threaded extension with which it is screwed into a threaded bushing 11 (FIG. 5) in an extension 10 of the hood 3.
- a line 12 leads from the threaded bushing to the arrangement 8, from whose turnout two high-frequency cables 13 and 14 originate.
- Another high-frequency cable 15 extends from the amplifier in the arrangement 7.
- the high-frequency cables 13, 14 and 15 lead into an inner sleeve 16, which is designed as an extension of the base plate 2.
- the inner sleeve 16 has a downwardly open, axially parallel slot 17 through which the RF cables 13, 14 and 15 are led out to the side.
- the inner sleeve 16 is provided with an internal thread 18 into which a screw 19 is turned.
- the screw 19 serves to press an outer sleeve 20, which is provided at its upper end with a flange 21 and can be pushed over the inner sleeve 16, against the underside of the body panel 4.
- the outer sleeve 20 has an upwardly open axially parallel slot 23, which in the installed position covers the slot 17 over a part of its length.
- couplers 27 are - preferably still in the manufacturer's factory - at the ends of the HF cables 13, 14 and 15 which are led out of the inner sleeve 16 and which are expediently coaxial cables , 28 and 29 attached.
- the HF cables 13, 14 and 15 are first inserted through the bore 30 provided for assembly in the body panel 4, followed by the inner sleeve 16. If the assembly is to be carried out on the roof of an automobile, the bore 30 is located Expediently over a roof strut 31, so that the RF cables 13, 14 and 15 can be continued in the automobile along the roof strut 31 (FIG. 2).
- the HF cables 13, 14 and 15 are first guided laterally into the slot 17 and pulled up against the body panel 4, as a result of which the HF cables are bent approximately at a right angle. So that they do not fall down again, they can now be connected to plugs which are located near the bore 30 at the ends of further high-frequency lines. However, these are not shown in the drawings.
- the outer sleeve 20 is then pushed over the inner sleeve 16 and fastened by screwing the screw 19 into the internal thread of the inner sleeve 16 , whereby the outer sleeve 20 with its flange 21 is pressed firmly against the underside of the body panel 4 (see FIG. 4).
- Figures 5 to 7 show a practical embodiment of a base part 1 of an antenna of the type shown in Figures 1 to 4, wherein the rod-shaped radiator is not yet screwed into the foot part 1.
- the threaded bushing 11 provided for this purpose is located in the extension 10 of the hood.
- Figure 5 shows the foot part 1 before the insertion of the RF cables 13, 14 and 15, which are bundled by bands 33 and 34.
- the HF cables first lead longitudinally out of the inner sleeve 16 and are thus passed through a hole in the body panel 4. Then, as shown in FIG. 6, but without showing the body panel, they are inserted into slot 17 and pulled up.
- the screw 19 is captively attached to the outer sleeve 20, e.g. by crimping the outer sleeve 20.
- a ground contact ring 37 is fastened, which has tapering projections 38 which are pressed against the body panel 4 when the screw 19 is firmly tightened and have good ground contact between the body panel and the outer sleeve 20 and thus also with the inner sleeve 16 and the base plate 2.
- FIG. 6 also shows a second seal 39 which is glued to the base plate 2 and surrounds the inner sleeve 16.
- a mandrel 40 (see FIG. 5) which extends downward from the base plate 2 and serves to engage in a further hole in the body panel.
- the mandrel 40 ensures that the foot part 1 on the body panel 4 cannot be rotated.
