Antenne für schnurlose Telefone
5Antenna for cordless phones

Antennen müssen mehrere Funktionen erfüllen, zum einen sollen sie flexibel und mechanisch hoch belastbar sein, zum anderen dürfen nur geringe Verluste durch Dämpfung auftreten. Außerdem muß sie Möglichkeiten zu ihrer mechanischen Befestigung aufweisen. Konventionelle Antennen bestehen aus einer Vielzahl von Teilen, die z. B. durch Kleben und Rasten miteinander verbunden sind. Zu ihrer Befestigung im Gehäuse eines Gerätes werden Schrauben oder Klemmen verwendet.Antennas must fulfill several functions: firstly, they must be flexible and able to withstand high mechanical loads, and secondly, they must only have minimal losses due to attenuation. They must also have options for mechanical fastening. Conventional antennas consist of a large number of parts that are connected to one another, for example by gluing or snapping. Screws or clamps are used to fasten them in the housing of a device.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Antenne für schnurlose Telefone aufzuzeigen, die einmal aus möglichst wenigen Teilen besteht und die zum anderen so gestaltet ist, daß sie eine einfache Festlegung innerhalb des schnurlosen Telefons gestattet.The present invention is therefore based on the object of demonstrating an antenna for cordless telephones which, on the one hand, consists of as few parts as possible and, on the other hand, is designed in such a way that it allows easy attachment within the cordless telephone.
Diese Aufgabe wird dadurch gelöst, daß die Antenne durch einen aus einer mit Kunststoff teilweise umspritzten Drahtwendel bestehenden Kern sowie durch eine auf diesem Kern aufschiebbare Hülle gebildet ist, wobei an der Hülle Halteelemente zur Festlegung der Antenne vorgesehen sind.This object is achieved in that the antenna is formed by a core consisting of a wire coil partially coated with plastic and by a sheath that can be pushed onto this core, with holding elements being provided on the sheath for securing the antenna.
Durch eine derartige Gestaltung der Antenne kann einmal die Anzahl der Teile erheblich reduziert werden, wobei die verbleibenden zwei Teile so gestaltet sein können, daß ein zusätzliches Befestigen mittels Klebe- oder Rastmittel nicht erforderlich ist. Durch eine entsprechende Gestaltung der Hülle kann weiterhin eine problemlose Befestigung der Antenne innerhalb des schnurlosen Telefons erreicht werden. Zur Befestigung der Antenne innerhalb des schnurlosen Telefons kann z.B. die Hülle aus einem zylinderförmigen und an einem Ende geschlossenen Körper und einem damit verbundenen Flansch bestehen, wobei der Flansch an seiner dem zylinderförmigen Kör-By designing the antenna in this way, the number of parts can be reduced considerably, whereby the remaining two parts can be designed in such a way that additional fastening by means of adhesive or locking means is not necessary. By designing the casing accordingly, the antenna can also be easily fastened inside the cordless telephone. To fasten the antenna inside the cordless telephone, the casing can, for example, consist of a cylindrical body that is closed at one end and a flange connected to it, whereby the flange is connected to the cylindrical body at its end.
per abgewandten Fläche zueinanderweisende, winkelförmige Ansätze besitzt. Durch eine derartige Gestaltung können die am Flansch vorgesehenen und zueinanderweisenden Ansätze in eine konturmäßig entsprechende Aufnahme eingreifen, so daß eine auch mittels eines Automaten durchführbare Befestigung der Antenne erfolgen kann. Um eine zwangsläufige Zentrierung des Kerns in bezug auf die Hülle zu erreichen, kann der Kern einen konisch gestalteten Endbereich besitzen, der mit einer ihm formmäßig angepaßten und im Bereich des Flansches vorgesehenen konischen Aufnahme zusammenarbeitet.per opposite surface has angular projections facing each other. With such a design, the projections provided on the flange and facing each other can engage in a correspondingly contoured receptacle, so that the antenna can be attached using a machine. In order to achieve a forced centering of the core in relation to the shell, the core can have a conical end region that works together with a conical receptacle that is adapted to its shape and provided in the area of the flange.
Die Erfindung soll im folgenden anhand eines Ausführungsbeispiels näher erläutert werden.The invention will be explained in more detail below using an embodiment.
Es zeigtIt shows
Figur 1 die Drahtwendel der Antenne in einer perspektivischen Ansicht,Figure 1 the wire coil of the antenna in a perspective view,
Figur 2 die umspritzte Drahtwendel vor dem Einbringen in die Hülle in einer perspektivischen Ansicht,Figure 2 shows the overmolded wire coil before insertion into the casing in a perspective view,
Figur 3 die zusammengebaute, teilweise geschnittene Antenne in einer perspektivischen Ansicht.Figure 3 shows the assembled, partially sectioned antenna in a perspective view.
Die in Figur 1 gezeigte und auf eine vorgegebene Frequenz abgestimmte Drahtwendel 1 besteht aus einer Mehrzahl von zueinander gleichmäßig beabstandeten Windungen 2. Ein freies Ende 3 der Drahtwendel 1 ist mehrfach abgewinkelt und dient zur elektrischen Verbindung der Antenne mit dem z. B. auf einer Leiterplatte in einem schnurlosen Telefon angeordneten Hochfrequenzteil .The wire coil 1 shown in Figure 1 and tuned to a given frequency consists of a plurality of turns 2 that are evenly spaced from one another. A free end 3 of the wire coil 1 is angled several times and serves to electrically connect the antenna to the high-frequency part arranged, for example, on a circuit board in a cordless telephone.
Wie aus der Figur 2 zu ersehen ist, besteht die Antenne 4 aus einem Kern 5 und einer den Kern 5 umfassenden Hülle 6. Der Kern wird durch die mit einem elastischen Kunststoff umspritzte Drahtwendel 1 gebildet. Durch Umspritzen der Draht-As can be seen from Figure 2, the antenna 4 consists of a core 5 and a sheath 6 that surrounds the core 5. The core is formed by the wire coil 1 that is overmolded with an elastic plastic. By overmold- ing the wire

5Coil 1 with plastic ensures that the distance between the turns always remains constant. The end area 7 of the core 5 serves to hold the free wire coil end 3 and is conical in shape.

Die Hülle 6 weist einen zylinderförmigen und an einem Ende geschlossenen Körper 8 sowie einen mit ihm verbundenen Flansch 9 auf. Am Flansch 9 sind zueinanderweisende winkelförmige Ansätze 10 vorgesehen, die zur Befestigung der Antenne an der hier nicht dargestellten Leiterplatte dienen. Die Hülle 6 ist im Bereich des Flansches 9 konisch zulaufend gestaltet. The casing 6 has a cylindrical body 8 that is closed at one end and a flange 9 connected to it. Angled projections 10 that point towards one another are provided on the flange 9 and are used to attach the antenna to the circuit board (not shown here). The casing 6 is designed to taper conically in the area of the flange 9.
Wie aus der Figur 3 zu ersehen ist, erfolgt beim Zusammenbau der Antenne, d. h. beim Einbringen des Kerns 5 in die Hülle 6 eine Zentrierung der beiden Teile zueinander aufgrund der konischen Gestaltung des Kerns 5 und der Hülle 6.As can be seen from Figure 3, when the antenna is assembled, i.e. when the core 5 is inserted into the casing 6, the two parts are centered relative to one another due to the conical design of the core 5 and the casing 6.
