Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß der Rastring durch einen metallischen Massering an der Tülle arretierbar ist, welcher in vorteilhafter Art und Weise gleichzeitig das Antennenelement der erfindungsgemäßen Antenne kapazitiv an Masse koppelt. Dieser kapazitive Masseanschluß der Antenne am Karosserieblech besitzt den Vorteil, daß hierdurch in besonders einfacher Art und Weise ohne Beschädigung des Karosserieblechs oder einer dieses überdekkenden Lackschicht eine gute Masseverbindung herstellbar ist.An advantageous development of the invention provides that the locking ring through a metallic earth ring can be locked on the spout, which is advantageous Way simultaneously the antenna element of the antenna according to the invention capacitively coupled to ground. This capacitive ground connection of the antenna on the body panel has the advantage that this makes it particularly simple and way without damaging the body panel or one that covers it Paint layer a good ground connection can be made.

Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, daß eine Abschirmung eines das Antennenelement der erfindungsgemäßen Antenne mit einem entsprechenden Sende- oder Empfangsgerät verbindenden Hochfrequenz-Kabels mittels eines aus Metall oder Kunststoff bestehenden Keils im Antennenelement befestigbar ist. Durch diese Vorgehensweise wird in vorteilhafter Art und Weise erreicht, daß das HF-Kabel ohne Löten oder Crimpen bei gleichzeitiger Zugentlastung besonders einfach befestigt werden kann. Another advantageous development of the invention provides that a shield one the antenna element of the antenna according to the invention with a Corresponding transmitting or receiving device connecting high-frequency cable by means of a wedge made of metal or plastic in the antenna element is attachable. This procedure advantageously and Way achieved that the RF cable without soldering or crimping at the same time Strain relief can be attached particularly easily.

Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, daß ein das Antennenelement umgebender und in die Tülle der erfindungsgemäßen Antenne einschiebbarer Isolationskörper mit auf seiner Außenfläche verlaufenden Spulenbahnen, die an ihren Enden in radial ins Innere dieses Isolationskörpers durchtretende Bohrungen übergehen, versehen ist. Diese erfindungsgemäße Maßnahme ermöglicht in vorteilhafter Art und Weise die Herstellung eines Sperrkreises mit gleichzeitiger Spulenbefestigung am Isolationskörper, ohne daß man gezwungen ist, den die Spule bildenden Draht am Antennenelement anzulöten oder zu crimpen.Another advantageous development of the invention provides that the antenna element surrounding and in the spout of the antenna according to the invention insertable insulation body with coil tracks running on its outer surface, the ends of which penetrate radially into the interior of this insulating body Pass holes, is provided.

Das in den Figuren 1 bis 6 dargestellte Ausführungsbeispiel einer einknüpfbaren Antenne, welche insbesondere als Kombiantenne für das D- oder E-Mobilfunknetz geeignet ist, gliedert sich prinzipiell in eine aus elastomerem Material bestehende Tülle 1, die in eine entsprechende Bohrung 2' eines Karosserieblechs 2 einsetzbar ist. In einem Innenraum 1' der hohlkegelförmig ausgeführten Tülle 1 ist ein Antennenelement 20 aufnehmbar, welches weiter unten noch näher beschrieben wird. Die Tülle 1 weist - in ebenfalls noch an und für sich bekannter Art und Weise - in ihrem unteren Bereich eine radial gerichtete Rastrille 3 auf, in der in eingesetztem Zustand der beschriebenen einknüpfbaren Antenne der Umfangsrand der Bohrung 2' des Karosserieblechs 2 aufnehmbar ist.The embodiment shown in Figures 1 to 6 of a linkable Antenna, which in particular as a combination antenna for the D or E mobile radio network is suitable, is basically divided into an elastomeric material existing spout 1, in a corresponding hole 2 'of a body panel 2 can be used. In an interior 1 'of the hollow cone Grommet 1 is an antenna element 20, which below is described in more detail. The spout 1 also - in still more known per se Way - in its lower area a radially directed locking groove 3rd on, in the inserted state of the insertable antenna described the peripheral edge of the bore 2 'of the body panel 2 can be received.

Wie nun ebenfalls aus Figur 1 ersichtlich ist, weist die Tülle eine radial verlaufende Vorrastrille 4 auf, welche in Einsteckrichtung X der Antenne gesehen vor der als umlaufende Nut ausgebildeten Rastrille 3 liegt. Diese Vorrastrille 4 erlaubt es in vorteilhafter Art und Weise, die Tülle 1 in einem ersten Montageschritt des Montagevorgangs in der Karosseriebohrung 2`' des Karosserieblechs 2 provisorisch zu arretieren, um sie dann - wie in Figur 2 dargestellt - mittels eines entsprechenden Hilfswerkzeuges H (s. Fig. 2) oder gegebenenfalls - was aber nicht bevorzugt wird - durch einen entsprechenden Zug von außen von ihrer in Figur 1 dargestellten Vorrast-Position, in der der Umfangsrand der Karosseriebohrung 2' in die Vorrastrille 4 eintaucht, in die in Figur 2 dargestellte endgültige Rastposition zu drücken, in der der Umfangsrand der Karosseriebohrung 2' in der Rastrille 3 aufgenommen ist. Hierbei wird die Tülle 1 gegen den Widerstand der zwischen der Vorrastrille 4 und der Rastrille 3 angeordneten umlaufenden Flanke 5 der Tülle 1, welche - wie die gesamte Tülle - aus elastischem Material besteht, bewegt. Hierzu taucht das Hilfswerkzeug H in einen an der unteren Stirnfläche 10 vorgesehehen, axial ausgerichteten Ringschlitz 11 ein. Dieser Ringschlitz 11 dient in vorteilhafter Art und Weise nicht nur zum Einsetzen der Tülle 1. Vielmehr bewirkt er auch eine Erhöhung der Elastizität der Tülle in diesem Bereich infolge der dadurch bewirkten Reduktion des zu deformierenden Tüllenmaterials.As can now also be seen from FIG. 1, the spout has a radial one Vorrastrille 4, which seen in the insertion direction X of the antenna in front of formed as a circumferential groove locking groove 3. This pre-groove 4 allows it in an advantageous manner, the spout 1 in a first assembly step Provisional assembly process in the body bore 2 '' of the body panel 2 to lock, then - as shown in Figure 2 - by means of an appropriate Auxiliary tool H (see Fig. 2) or if necessary - but not is preferred - by a corresponding pull from the outside in FIG. 1 illustrated pre-locking position in which the peripheral edge of the body bore 2 ' immersed in the preliminary groove 4, in the final shown in Figure 2 To press the locking position in which the peripheral edge of the body bore 2 'in the Locking groove 3 is added. Here, the spout 1 against the resistance of the between the pre-groove 4 and the locking groove 3 arranged circumferential flank 5 of the spout 1, which - like the entire spout - consists of elastic material, emotional. For this purpose, the auxiliary tool H dips into one on the lower end face 10 provided, axially aligned ring slot 11. This ring slot 11 advantageously serves not only for inserting the spout 1. Rather it also causes an increase in the elasticity of the spout in this area as a result the resulting reduction in the sleeve material to be deformed.

Vorzugsweise weist der Ringschlitz 11 im Bereich der Rastrille 3 desweiteren einen Hohlraum 12 auf, der beim Eindrücken des Hilfswerkzeugs H in den Ringschlitz 11 gestreckt wird und außerdem die Wandstärke der Tülle 1 in diesem Bereich noch weiter reduziert, wodurch in vorteilhafter Art und Weise infolge des nochmals leichteren elastischen Deformierbarkeit der Tülle 1 der Montagevorgang der beschriebenen Antenne nochmals erleichtert wird.The ring slot 11 preferably also has one in the region of the locking groove 3 Cavity 12, which when pressing the auxiliary tool H into the ring slot 11 is stretched and also the wall thickness of the spout 1 in this area even further reduced, which advantageously due to the even easier elastic deformability of the spout 1 the assembly process the antenna described is further facilitated.

Nach diesen eben genannten Maßnahmen erfolgt nun eine radiale und axiale Dichtung der Tülle 1 in der Karosseriebohrung 2' des Karosserieblechs 2, indem von der Stirnseite 10 der Tülle 1 her ein auf den Ringschlitz 11 und eventuell den Hohlraum 12 abgestimmter Rastring 13 eingeschoben und mit Hilfe eines Masserings 14 verriegelt wird, so daß die Tülle 1 nun nicht mehr von außen in die Bohrung 2' des Karosserieblechs 2 zurückgedrückt werden kann. Die Arretierung des Rastrings 13 in dem Ringschlitz 11 erfolgt hierbei in vorteilhafter Art und Weise durch ein in den Ringschlitz 11 ragendes Teil 14a des Masserings 14. Dieses Teil 14a hintergreift - wie am besten aus Figur 3 ersichtlich ist - eine am externen Rastring 13 angeordnete umlaufende Schulter 13' und arretiert derart den Rastring 13 an der Tülle 1 der Antenne. Eine derartige Konstruktion besitzt den Vorteil einer geringen Einbautiefe. After these measures just mentioned, there is now a radial and axial Seal the grommet 1 in the body bore 2 'of the body panel 2 by from the end face 10 of the spout 1 on the ring slot 11 and possibly the Cavity 12 coordinated locking ring 13 inserted and with the help of a mass ring 14 is locked so that the spout 1 is no longer from the outside in the bore 2 'of the body panel 2 can be pushed back. The locking of the Locking ring 13 in the ring slot 11 takes place in an advantageous manner by a part 14a of the mass ring 14 projecting into the ring slot 11 Part 14a engages behind - as can best be seen in FIG. 3 - on the external one Locking ring 13 arranged circumferential shoulder 13 'and thus locks the Locking ring 13 on the spout 1 of the antenna. Such a construction has the Advantage of a small installation depth.

Wie am besten aus Figur 4 ersichtlich ist, dient der Massering 14 nicht nur zur mechanischen Befestigung der Antenne in der Karosseriebohrung 2' des Karosserieblechs 2. Vielmehr wird durch den vorzugsweise aus Edelstahl bestehenden Masserings 14 eine kapazitive Ankopplung der Antenne an Masse erreicht. Hierzu ist zwischen dem elektrisch leitenden Karosserieblech 3 und zumindest einem Teil der Ringfläche 14' des Masserings 14 ein Dielektrikum angeordnet, welches vorzugsweise als Dielektrikum-Klebefolie, als Beschichtung oder als Lack, etc. auf dem Karosserieblech 2 und/oder der Ringfläche 14' des Masserings 14 ausgeführt ist. Desweiteren weist der Massering 14 zum kapazitiven Masseanschluß fächerartige Federsegmente 15a-15h in ringförmiger Anordnung auf, die ebenfalls vorzugsweise aus Edelstahl ausgeführt sind.As can best be seen from FIG. 4, the mass ring 14 is not only used for mechanical fastening of the antenna in the body bore 2 'of the body panel 2. Rather, it is made of stainless steel Masserings 14 achieved a capacitive coupling of the antenna to ground. For this is between the electrically conductive body panel 3 and at least one Part of the annular surface 14 'of the earth ring 14 arranged a dielectric, which preferably as a dielectric adhesive film, as a coating or as a varnish, etc. on the body panel 2 and / or the annular surface 14 'of the mass ring 14 is. Furthermore, the ground ring 14 has a capacitive ground connection fan-like spring segments 15a-15h in an annular arrangement, which also are preferably made of stainless steel.

In den Figuren 5 und 6 sind nun Details der Ausbildung des Antennenelements 20 dargestellt. Von Vorteil ist die am besten aus Figur 5 ersichtliche Fixierung eines die beschriebene Antenne mit einem entsprechenden Sende-/Empfangsgerät verbindenden Hochfrequenz-Kabels 30. Hierbei ist vorgesehen, daß eine Abschirmung 31 des HF-Kabels 30 mittels eines aus Metall oder Kunststoff ausgebildeten Keils 32 an ein Masseteil 21 des Antennenelements 20 gepreßt wird. Eine derartige Vorgehensweise besitzt nicht nur den Vorteil, daß ein sicherer Massekontakt und - bei einem metallischen Teil - annähernd keine Impedanzänderung an dieser Stelle auftritt. Vielmehr wird durch die beschriebene Konstruktion auch eine Zugentlastung für das HF-Kabel 30 ausgebildet. Von Vorteil ist weiterhin, daß die Abschirmung 31 des HF-Kabels 30 besonders einfach und ohne Crimpen mit dem Masseteil 21 des Antennenelements 20 verbunden werden kann.FIGS. 5 and 6 now show details of the design of the antenna element 20 shown. The fixation of one best seen in FIG. 5 is advantageous the antenna described with a corresponding transceiver connecting high-frequency cable 30. It is provided that a shield 31 of the HF cable 30 by means of a metal or plastic Wedge 32 is pressed to a mass part 21 of the antenna element 20. A Such an approach not only has the advantage that a safe ground contact and - for a metallic part - almost no change in impedance occurs at this point. Rather, the construction described also a strain relief for the RF cable 30 is formed. Another advantage is that the shield 31 of the RF cable 30 is particularly simple and without Crimping can be connected to the ground part 21 of the antenna element 20 can.

In Figur 6 ist nun eine besonders einfache Art und Weise zur Herstellung und Montage eines Sperrkreises auf dem Antennenelement 20 der beschriebenen Antenne dargestellt. Auf einem den oberen Teil 20a des Antennenelements 20 umgebenden Isolationskörpers 23 ist eine als Spulenbahn dienende, wendelförmig verlaufende Nut 25 angeordnet. Die wendelförmige Nut 25 geht an ihren beiden Enden in jeweils eine radial verlaufende Bohrung 26, 26' über, welche von der Außenseite des Isolationskörpers 23 bis zu dessen das Antennenelement 20 aufnehmenden Innenraum 23' reicht. Zur Herstellung dieses Sperrkreises wird in einem ersten Sperrkreis-Montageschritt ein die Spule des Sperrkreises ausbildender Draht 27 durch die obere Bohrung 26 derart weit in das Innere 23' des Isolierkörpers 23 gesteckt, daß durch ein geringfügiges Einschieben eines oberen Strahlers 20a des Antennenelements 20 in den Innenraum 23' des Isolierkörpers 23 eine Klemmung des Drahtes 27 zwischen der Außenfläche 20' des Antennenelements 20 und der Innenfläche 23a des Isolationskörpers 23 erreicht und derart ein zuverlässiger Kontakt zwischen dem Draht 27 und dem Antennenelement 20 hergestellt wird. Nachdem der Draht 27 derart an seinem vorderen Ende fixiert wurde, wird in dem darauffolgenden Sperrkreis-Montageschritt der Draht 27 entlang der die Spulenbahn bildenden wendelförmigen Nut 25 gewickelt und danach entsprechend abgelängt, um durch die am unteren Ende der Spulenbahn befindliche, radial bis in den Innenraum 23' des den Spulenkem bildenden Isolationskörpers 23 tretende weitere Öffnung 26' gesteckt und durch ein Einschieben eines weiteren Strahlerelements 20b des Antennenelements 20 eingepreßt zu werden.FIG. 6 shows a particularly simple way of producing and Mounting a blocking circuit on the antenna element 20 of the described Antenna shown. On an upper part 20a of antenna element 20 surrounding insulation body 23 is a helical serving as a coil track extending groove 25 arranged. The helical groove 25 goes to hers both ends in a radially extending bore 26, 26 ', which of the outside of the insulation body 23 up to which the antenna element 20 receiving interior 23 'is sufficient. To create this blocking circuit is in a first blocking circuit assembly step forming the coil of the blocking circuit Wire 27 through the upper bore 26 so far into the interior 23 'of the Insulating 23 inserted that a slight insertion of an upper Radiator 20a of the antenna element 20 in the interior 23 'of the insulating body 23 a clamping of the wire 27 between the outer surface 20 'of the antenna element 20 and the inner surface 23a of the insulating body 23 is reached and such a reliable contact between the wire 27 and the antenna element 20 is manufactured. After the wire 27 is so on its front End has been fixed in the subsequent blocking circuit assembly step the wire 27 is wound along the helical groove 25 forming the coil path and thereafter cut to length by the at the bottom of the Coil path located radially into the interior 23 'of the one forming the coil core Insulating body 23 entering further opening 26 'and inserted through Pushing in another radiator element 20b of the antenna element 20 to become.

Zusammenfassend ist festzustellen, daß sich die beschriebene Antenne nicht nur dadurch auszeichnet, daß sie besonders einfach hergestellt werden kann. Vielmehr ermöglicht es der beschriebene Aufbau desweiteren, daß die Antenne von einer einzigen Person vom Innenraum einer Fahrzeugkarosserie her, ohne Zuhilfenahme einer Hilfskraft, montiert werden kann.In summary, it should be noted that the antenna described is not only characterized in that it can be manufactured particularly easily. Much more Furthermore, the construction described enables the antenna from a single person from the interior of a vehicle body, without assistance an assistant, can be assembled.
