Abstract

The antenna comprises a tube-shaped flange (30) and a coupling (20) set at an angle of 90 degrees. The sleeve (10) continues upward and accommodates the wire (40), while the flange possesses a circumferential groove for catching in a recess, with a double undercut, in the housing. The flange is made with a slot for locating in the recess to prevent radial play, and the sleeve is made of flexible material.

Description

Die Erfindung bezieht sich auf eine universielle, abgewinkelte Stabantenne für Basisstationen und/oder Mobilteile schnurloser Telefonsysteme.The invention relates to a universal, angled rod antenna for base stations and / or mobile parts of cordless telephone systems.

Schnurlose Telefonsysteme bestehen aus einer Basisstation und ein oder mehreren zugeordneten Mobilteilen. Die zwischen Basisstation und Mobilteilen vorhandene Funkschnittstelle benötigt auf jeder Seite eine Antenne. Diese Antennen sind, zumindest an der Basisstation, schwenkbar angeordnet. Derartige Antennen wurden bislang der jeweiligen Gehäuseform angepaßt, so daß aus konstruktiver Sicht die Antennen bei jeder Modelländerung neu zu schaffen waren.Cordless telephone systems consist of a base station and one or more assigned handsets. The radio interface between the base station and handsets requires an antenna on each side. These antennas are pivotably arranged, at least at the base station. Such antennas have so far been adapted to the respective housing shape, so that from a constructional point of view the antennas had to be created anew with each model change.

Der Erfindung lag die Aufgabe zugrunde, eine drehbar gelagerte Antenne zu schaffen, die universiell für unterschiedliche Modellformen verwendbar ist, die leicht montierbar und demontierbar ist, die außerdem Varianten hinsichtlich der Länge des Antennendrahtes, die abhängig von der Sende- und Empfangsfrequenz ist, und der Formgebung gestattet.The invention had for its object to provide a rotatably mounted antenna that can be used universally for different model shapes, that is easy to assemble and disassemble, and also variants with regard to the length of the antenna wire, which is dependent on the transmission and reception frequency, and Shape allowed.

Diese Aufgabe ist durch die Erfindung gelöst, wie sie im ersten Schutzanspruch dargelegt ist. Weitere vorteilhafte Maßnahmen sind Gegenstand der Unteransprüche.This object is achieved by the invention as set out in the first claim for protection. Further advantageous measures are the subject of the subclaims.

Die Erfindung wird nachfolgend anhand einer aus vier Figuren bestehenden Zeichnung näher erläutert. In der Zeichnung zeigen die

Die abgewinkelte Stabantenne setzt sich aus einer elastischen Hülse 10 und einem rohrförmigen Flansch 30 mit winklig angesetzter Kupplung 20 zusammen. Die Hülse 10 weist eine Nut auf, durch die sie mittels einer Rastverbindung auf dem Flansch 30 befestigt wird. Durch den Flansch 30 wird der Antennendraht 40 in die Hülse 10 eingefädelt.The angled rod antenna is composed of an elastic sleeve 10 and a tubular flange 30 with an angled coupling 20. The sleeve 10 has a groove through which it is attached to the flange 30 by means of a snap connection. The antenna wire 40 is threaded into the sleeve 10 through the flange 30.

Die Antenne wird in einer Ausnehmung 60 eines Gehäuses 70 gelagert. Hierzu ist der Flansch 30 mit einer umlaufenden Nut 50 versehen. Die Ausnehmung 60 weist eine zweifache Hinterschneidung 80 auf, die beim Einrasten des Flansches 30 dessen Selbstzentrierung im Gehäuse 70 bewirkt. Der Flansch 30 ist an dem in das Gehäuse 70 rastenden rohrförmigen Teil in Längsrichtung mit einem Schlitz 90 versehen. Durch diesen Schlitz 90 wird der Flansch 30 unter radialer Spannung in der Ausnehmung 60 geführt. Damit ist ein radiales Lagerspiel vermieden und eine definierte Lagerreibung erzeugt.The antenna is stored in a recess 60 in a housing 70. For this purpose, the flange 30 is provided with a circumferential groove 50. The recess 60 has a double undercut 80 which, when the flange 30 engages, causes it to self-center in the housing 70. The flange 30 is provided with a slot 90 in the longitudinal direction on the tubular part which snaps into the housing 70. The flange 30 is guided through this slot 90 under radial tension in the recess 60. This avoids radial bearing play and generates a defined bearing friction.

Die universelle Verwendbarkeit des Flansches und die geringen Herstellungskosten für die Hülse ermöglichen wirtschaftliche Antennenvarianten. Der Antennenaufbau gestattet zudem durch Aufstecken verschiedenartiger Hülsen die Antenne der Formgebung des Gerätes anzupassen.The universal usability of the flange and the low manufacturing costs for the sleeve enable economical antenna variants. The antenna structure also allows the antenna to be adapted to the shape of the device by attaching different types of sleeves.

Durch die einfache Demontage durch Abziehen der Hülse vom Flansch können die Einzelteile leichter einer Werkstoffrückgewinnung zugeführt werden.By simply disassembling the sleeve from the flange, the individual parts can be more easily recycled.
