Beschreibungdescription
Die Erfindung betrifft eine einknüpfbare Antenne, insbesondere für Kraftfahrzeu¬ ge, die eine Tülle aus elastomerem Material aufweist, welche in ihrem unteren Bereich mit einer umlaufenden Rastrille zur Aufnahme eines Umfangsrandes ei¬ ner Öffnung einer die Antenne tragenden Fläche versehen ist und in der ein An¬ tennenelement der Antenne aufnehmbare ist.The invention relates to a snap-in antenna, in particular for motor vehicles, which has a grommet made of elastomeric material, which is provided in its lower region with a circumferential locking groove for receiving a peripheral edge of an opening of a surface supporting the antenna, and in which a connector ¬ antenna element is receivable.
Eine derartige einknüpfbare Antenne ist aus der DE-4037712 C2 und aus der DE-4005 029 C2 bekannt. Die DE 4037 712 C2 offenbart darüber hinaus eine kapazitive Masseankopplung der Antenne. Nachteilig daran ist, daß der Monta¬ gevorgang der Antenne in einer Karosseriebohrung eines Karosserieblechs eines Kraftfahrzeuges nicht von einem einzigen Mechaniker vom Innenraum dieses Kraftfahrzeuges aus durchführbar ist. Es ist daher Aufgabe der Erfindung, eine einknüpfbare Antenne der eingangs ge¬ nannten Art derart weiterzuentwickeln, daß die Montage erleichter wird.Such a plug-in antenna is known from DE-4037712 C2 and from DE-4005 029 C2. DE 4037 712 C2 also discloses a capacitive ground coupling of the antenna. The disadvantage of this is that the assembly process of the antenna in a body hole in a body panel of a motor vehicle cannot be carried out by a single mechanic from the interior of this motor vehicle. It is therefore an object of the invention to further develop a plug-in antenna of the type mentioned at the outset in such a way that assembly is made easier.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Tülle in ihrer unte¬ ren Stirnfläche eine axial gerichtete, ringförmige Ausnehmung aufweist, in die von der unteren Stirnfläche der Tülle her ein an dieser arretierbarer Rastring ein¬ schiebbar ist.This object is achieved according to the invention in that the spout has an axially directed, annular recess in its lower end face, into which a locking ring which can be locked at this end can be inserted from the lower end face of the spout.
Durch die erfindungsgemäßen Maßnahmen wird in vorteilhafter Art und Weise er¬ reicht, daß nunmehr die Montage der erfindungsgemäßen einknüpfbaren Anten¬ ne durchgeführt werden kann, ohne daß der Mechaniker gezwungen ist, sich der Unterstützung einer zweiten Person zu bedienen oder während des Montgevor- gangs den Innenraum der Karosserie des mit der erfindungsgemäßen Antenne auszurüstenden Kraftfahrzeugs zu verlassen.The measures according to the invention advantageously achieve that the assembly of the antenna according to the invention that can be connected can now be carried out without the mechanic being forced to use the support of a second person or during the assembly process Leaving the interior of the body of the motor vehicle to be equipped with the antenna according to the invention.
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 Anten¬ ne 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 überdek- kenden Lackschicht eine gute Masseverbindung herstellbar ist.An advantageous further development of the invention provides that the locking ring can be locked on the grommet by a metallic earth ring, which at the same time advantageously capacitively couples the antenna element of the antenna according to the invention to ground. This capacitive ground connection of the antenna to the body panel has the advantage that a good ground connection can be established in a particularly simple manner without damaging the body panel or a paint layer covering it.
Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, daß eine Abschir¬ mung eines das Antennenelement der erfindungsgemäßen Antenne mit einem entsprechenden Sende- oder Empfangsgerät verbindenden Hochfrequenz-Ka¬ bels mittels eines aus Metall oder Kunststoff bestehenden Keils im Antennenele- ment 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. Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, daß ein das An¬ tennenelement umgebender und in die Tülle der erfindungsgemäßen Antenne einschiebbarer Isolationskörper mit auf seiner Außenfläche verlaufenden Spulen¬ bahnen, die an ihren Enden in radial ins Innere dieses Isolationskörpers durchtre- tende Bohrungen übergehen, versehen ist. Diese erfindungsgemäße Maßnahme ermöglicht in vorteilhafter Art und Weise die Herstellung eines Sperrkreises mit gleichzeitiger Spulenbefestigung am Isoiationskörper, ohne daß man gezwungen ist, den die Spule bildenden Draht am Antennenelement anzulöten oder zu crimpen.A further advantageous development of the invention provides that a shielding of a high-frequency cable connecting the antenna element of the antenna according to the invention to a corresponding transmitting or receiving device can be fastened in the antenna element by means of a wedge made of metal or plastic. This procedure advantageously ensures that the HF cable can be attached in a particularly simple manner without soldering or crimping and with simultaneous strain relief. A further advantageous development of the invention provides that an insulation body surrounding the antenna element and insertable into the grommet of the antenna according to the invention with coil tracks running on its outer surface, which at their ends merge into bores penetrating radially into the interior of this insulation body. is provided. This measure according to the invention advantageously enables the production of a blocking circuit with simultaneous coil attachment to the insulation body without being forced to solder or crimp the wire forming the coil to the antenna element.

Das in den Figuren 1 bis 6 dargestellte Ausführungsbeispiel einer eiπkπüpfbaren Antenne, welche insbesondere als Kombiantenne für das D- oder E-Mobil- funknetz geeignet ist, gliedert sich prinzipiell in eine aus elastomerem Material bestehende Tülle 1 , die in eine entsprechende Bohrung 2' eines Karosse- rieblechs 2 einsetzbar ist. In einem Innenraum 1' der hohlkegelförmig ausgeführ¬ ten 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 be¬ kannter 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 exemplary embodiment shown in FIGS. 1 to 6 of an insertable antenna, which is particularly suitable as a combination antenna for the D or E mobile radio network, is in principle divided into a spout 1 made of elastomeric material, which fits into a corresponding bore 2 'of a Body panel 2 can be used. An antenna element 20, which will be described in more detail below, can be received in an interior 1 'of the hollow-conical nozzle 1. The grommet 1 also has a radially directed latching groove 3 in its lower area, which is also known per se and in which the circumferential edge of the bore 2 'of the body panel 2 can be received in the inserted state of the insertable antenna described .
Wie nun ebenfalls aus Figur 1 ersichtlich ist, weist die Tülle eine radial verlaufen¬ de 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 proviso¬ risch zu arretieren, um sie dann - wie in Figur 2 dargestellt - mittels eines ent¬ sprechenden 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 grommet has a radially extending pre-notch 4, which, seen in the insertion direction X of the antenna, lies in front of the detent groove 3 which is designed as a circumferential groove. This preliminary groove 4 advantageously allows the grommet 1 to be provisionally locked in the body bore 2 ″ of the body panel 2 in a first assembly step of the assembly process, in order then - as shown in FIG. 2 - by means of an appropriate auxiliary tool H (see FIG. 2) or possibly - but this is not preferred - by a corresponding pull from the outside from its pre-locking position shown in FIG Figure 2 shown final To press the locking position in which the peripheral edge of the body bore 2 'is received in the locking groove 3. Here, the spout 1 is moved against the resistance of the circumferential flank 5 of the spout 1 arranged between the pre-groove 4 and the detent groove 3, which - like the entire spout - consists of elastic material. For this purpose, the auxiliary tool H is immersed in an axially aligned annular slot 11 provided on the lower end face 10. This ring slot 11 advantageously serves not only to insert the spout 1. Rather, it also causes an increase in the elasticity of the spout in this area as a result of the reduction in the spout material to be deformed thereby.
Vorzugsweise weist der Ringschlitz 11 im Bereich der Rastrille 3 desweiteren ei¬ nen Hohlraum 12 auf, der beim Eindrücken des Hilfswerkzeugs H in den Ring¬ schlitz 11 gestreckt wird und außerdem die Wandstärke der Tülle 1 in diesem Be¬ reich noch weiter reduziert, wodurch in vorteilhafter Art und Weise infolge des nochmals leichteren elastischen Deformierbarkeit der Tülle 1 der Montagevor- gang der beschriebenen Antenne nochmals erleichtert wird.The ring slot 11 preferably also has a cavity 12 in the area of the locking groove 3, which is stretched when the auxiliary tool H is pressed into the ring slot 11 and also further reduces the wall thickness of the spout 1 in this area, which means that advantageously, the assembly process of the antenna described is further facilitated due to the even easier elastic deformability of the grommet 1.
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 Masse- rings 14 verriegelt wird, so daß die Tülle 1 nun nicht mehr von außen in die Boh¬ rung 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 denAfter these measures just mentioned, a radial and axial seal of the spout 1 in the body bore 2 'of the body panel 2 now takes place by inserting a locking ring 13 matched to the ring slot 11 and possibly the cavity 12 from the end face 10 of the spout 1 and with the aid a mass ring 14 is locked so that the grommet 1 can no longer be pressed from the outside into the bore 2 'of the body panel 2. The locking ring 13 is locked in the ring slot 11 in an advantageous manner by a part 14a of the earth ring 14 projecting into the ring slot 11. This part 14a engages - as can best be seen in FIG. 3 - a circumferential one arranged on the external locking ring 13 Shoulder 13 'and locked in such a way
Rastring 13 an der Tülle 1 der Antenne. Eine derartige Konstruktion besitzt den Vorteil einer geringen Einbautiefe. Wie am besten aus Figur 4 ersichtlich ist, dient der Massering 14 nicht nur zur mechanischen Befestigung der Antenne in der Karosseriebohrung 2' des Karos¬ serieblechs 2. Vielmehr wird durch den vorzugsweise aus Edelstahl bestehenden Masserings 14 eine kapazitive Ankopplung der Antenne an Masse erreicht. Hier- zu 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 aus¬ geführt ist. Desweiteren weist der Massering 14 zum kapazitiven Masseanschluß fächerartige Federsegmente 15a-15h in ringförmiger Anordnung auf, die eben¬ falls vorzugsweise aus Edelstahl ausgeführt sind.Locking ring 13 on the spout 1 of the antenna. Such a construction has the advantage of a small installation depth. As can best be seen from FIG. 4, the earth ring 14 serves not only for mechanically fastening the antenna in the body bore 2 'of the body panel 2. Rather, the earth ring 14, which is preferably made of stainless steel, achieves a capacitive coupling of the antenna to ground. For this purpose, a dielectric is arranged between the electrically conductive body sheet 3 and at least part of the ring surface 14 ′ of the mass ring 14, which dielectric is preferably used as a dielectric adhesive film, as a coating or as a varnish, etc. on the body sheet 2 and / or the ring surface 14 'of the mass ring 14 is executed. Furthermore, for the capacitive ground connection, the earth ring 14 has fan-like spring segments 15a-15h in an annular arrangement, which are also 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 ei¬ nes die beschriebene Antenne mit einem entsprechenden Sende-/Empfangsgerät verbindenden Hochfrequenz-Kabels 30. Hierbei ist vorgesehen, daß eine Ab¬ schirmung 31 des HF-Kabels 30 mittels eines aus Metall oder Kunststoff ausge¬ bildeten Keils 32 an ein Masseteil 21 des Antennenelements 20 gepreßt wird. Ei¬ ne derartige Vorgehensweise besitzt nicht nur den Vorteil, daß ein sicherer Mas¬ sekontakt und - bei einem metallischen Teil - annähernd keine Impedanzäπde- rung an dieser Stelle auftritt. Vielmehr wird durch die beschriebene Konstruktion auch eine Zugentlastung für das HF-Kabel 30 ausgebildet. Von Vorteil ist weiter¬ hin, 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. The fixation of the described antenna, which can best be seen in FIG. 5, is advantageous. The high-frequency cable 30 connects this with a corresponding transceiver. It is provided that a shield 31 of the HF cable 30 is made of metal or Plastic wedge 32 is pressed against a mass part 21 of the antenna element 20. Such a procedure not only has the advantage that a safe ground contact and - in the case of a metallic part - almost no change in impedance occurs at this point. Rather, the construction described also provides a strain relief for the HF cable 30. Another advantage is that the shield 31 of the HF cable 30 can be connected to the ground part 21 of the antenna element 20 in a particularly simple manner and without crimping.
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, wendeiför¬ mig verlaufende Nut 25 angeordnet. Die wendeiförmige 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 ausbil- dender Draht 27 durch die obere Bohrung 26 derart weit in das Innere 23' des Isolierkörpers 23 gesteckt, daß durch ein geringfügiges Einschieben eines obe¬ ren Strahlers 20a des Antennenelements 20 in den Innenraum 23' des Isolierkör¬ pers 23 eine Klemmung des Drahtes 27 zwischen der Außenfläche 20' des An¬ tennenelements 20 und der Innenfläche 23a des Isolationskörpers 23 erreicht und derart ein zuverlässiger Kontakt zwischen dem Draht 27 und dem Anten¬ nenelement 20 hergestellt wird. Nachdem der Draht 27 derart an seinem vorde¬ ren Ende fixiert wurde, wird in dem darauffolgenden Sperrkreis-Montageschritt der Draht 27 entlang der die Spulenbahn bildenden wendeiförmigen Nut 25 ge¬ wickelt und danach entsprechend abgelängt, um durch die am unteren Ende der Spulenbahn befindliche, radial bis in den Innenraum 23' des den Spulenkern bil¬ denden Isolationskörpers 23 tretende weitere Öffnung 26' gesteckt und durch ein Einschieben eines weiteren Strahlerelements 20b des Antennenelements 20 ein¬ gepreßt zu werden.FIG. 6 shows a particularly simple way of producing and installing a blocking circuit on the antenna element 20 of the antenna described. Arranged on an insulating body 23 surrounding the upper part 20a of the antenna element 20 is a groove 25 which serves as a coil path and extends in a helical shape. The helical groove 25 goes to hers both ends in a radially extending bore 26, 26 ', which extends from the outside of the insulation body 23 to the interior 23' receiving the antenna element 20. To produce this blocking circuit, in a first blocking circuit assembly step, a wire 27 forming the coil of the blocking circuit is inserted through the upper bore 26 into the interior 23 'of the insulating body 23 to such an extent that by slightly inserting an upper radiator 20a Antenna element 20 in the interior 23 'of the insulating body 23 achieves 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 and thus reliable contact between the wire 27 and the antenna element 20 will be produced. After the wire 27 has been fixed at its front end in this way, in the subsequent blocking circuit assembly step, the wire 27 is wound along the helical groove 25 forming the coil path and then cut to length to pass through the groove located at the lower end of the coil path. to be inserted radially into the interior 23 'of the insulation body 23 forming the coil core 23 and to be pressed in by inserting a further radiator element 20b of the antenna element 20.
Zusammenfassend ist festzustellen, daß sich die beschriebene Antenne nicht nur dadurch auszeichnet, daß sie besonders einfach hergestellt werden kann. Viel¬ mehr ermöglicht es der beschriebene Aufbau desweiteren, daß die Antenne von einer einzigen Person vom Innenraum einer Fahrzeugkarosserie her, ohne Zuhil¬ fenahme einer Hilfskraft, montiert werden kann. In summary, it can be stated that the antenna described is not only distinguished by the fact that it can be manufactured particularly easily. Rather, the structure described further enables the antenna to be installed by a single person from the interior of a vehicle body, without the aid of an assistant.
