Description

Innerhalb eines Kommunikationsendgerätes angeordneter Tonruf- wandler Ringing transducer arranged within a communication terminal
Die vorliegende Erfindung beinhaltet einen innerhalb eines aus zwei Gehäuseteilen bestehenden Kommunikationsendgerätes angeordneten Tonrufwandler. Die Befestigung eines Tonrufwand- lers innerhalb eines Kommunikationsendgerätes erfolgte bisher z. B. dadurch, daß der Tonrufwandler mit seinen Anschlüssen direkt auf eine Leiterplatte aufgesteckt und mit den An¬ schlußpunkten auf der Leiterplatte verlötet wurde. Da ein Tonrufwandler aufgrund seiner Abmessungen relativ viel Platz auf der Leiterplatte benötigt, stand dieser Raum unterhalb des Tonrufwandlers auf der Leiterplatte zum Einbringen ande¬ rer elektrischer oder elektronischer Bauteile nicht mehr zur Verfügung.The present invention includes a ringer arranged within a communication terminal consisting of two housing parts. The attachment of a ringer within a communication terminal has been done so far. B. in that the ringer was plugged with its connections directly onto a circuit board and soldered to the connection points on the circuit board. Since a ringing transducer requires a relatively large amount of space on the circuit board due to its dimensions, this space below the ringing transducer on the circuit board was no longer available for inserting other electrical or electronic components.
Weiterhin ist es bekannt, den Tonrufwandler mit einem der Ge¬ häuseteile zu verschrauben oder zu verrasten. Bei dieser Art der Befestigung war der Tonrufwandler nicht mehr Bestandteil einer auf einer Leiterplatte untergebrachten Baugruppe, son- dem von dieser Baugruppe losgelöst und lediglich mit seinen Anschlüssen mit der Baugruppe bzw. der Leiterplatte verbun¬ den.Furthermore, it is known to screw or lock the ringer to one of the housing parts. With this type of attachment, the ringer was no longer part of an assembly housed on a printed circuit board, but detached from this assembly and only connected with its connections to the assembly or the printed circuit board.
Da bei Massenprodukten immer eine möglichst rationelle Ferti¬ gung verfolgt wird, ist man bestrebt, den Tonruf andler in eine auf einer Leiterplatte untergebrachte Baugruppe zu inte¬ grieren, wobei der Platz unterhalb des Tonrufwandlers auf der Leiterplatte für weitere Bauelemente nutzbar sein soll.Since the most efficient production possible is always pursued in mass-produced products, efforts are made to integrate the ringer into a module housed on a circuit board, the space below the ringer converter on the circuit board should be usable for further components.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Tonrufwandler innerhalb eines Kommunikationsendgerätes lagerichtig so zu befestigen, daß der Montageaufwand so ge¬ ring wie möglich gehalten werden kann. Diese Aufgabe wird dadurch gelöst, daß der Tonrufwandler mit einem separaten Halter formschlüssig verbunden ist, wobei dieser Halter und zumindest eines der Gehäuseteile so ausge- bildet sind, daß der Halter zwischen den beiden Gehäuseteilen geklemmt und zentriert gehalten ist.The present invention is therefore based on the object of fastening a ringing transducer in the correct position within a communication terminal so that the assembly effort can be kept as low as possible. This object is achieved in that the ringer is positively connected to a separate holder, this holder and at least one of the housing parts being designed in such a way that the holder is clamped and held centered between the two housing parts.
Eine derartige Befestigungsart ermöglicht eine problemlose und einfache Montage des Tonrufwandlers innerhalb des Kommu- nikationsendgerätes, da in diesem Fall lediglich der Tonruf- wandler in den separaten Halter eingebaut werden muß, wobei anschließend dieser den Tonrufwandler aufnehmende Halter auf¬ grund seiner Gestaltung und zumindest eines der Gehäuseteile zwischen den Gehäuseteilen geklemmt und zentriert gehalten wird. Hierzu bedarf es also keiner zusätzlichen Hilfsmittel in Form von Schrauben oder Klammern, so daß dieser Montage¬ schritt entfallen kann.Such a type of fastening enables problem-free and simple assembly of the ringing transducer within the communication terminal, since in this case only the ringing transducer has to be installed in the separate holder, after which the holder holding the ringing transducer due to its design and at least one of the Housing parts clamped between the housing parts and kept centered. No additional aids in the form of screws or clips are required for this, so that this assembly step can be omitted.
Gemäß einem bevorzugten Ausführungsbeispiel kann der separate Halter als ringförmiger Körper gestaltet sein und mit einem hochgezogenen Randbereich den Tonrufwandler teilweise um¬ schließen, wobei ferner am Halter Rasthaken vorgesehen sind, die am Tonrufwandler in Stegen angeordnete Durchbrüche hin- ' tergreifen, wobei ferner der Halter an seiner den Rasthaken abgewandten Ringfläche mehrere Abstandshalter besitzt und im Basisbereich mehrere in den Innenraum des Körpers hineinra¬ gende Federlappen aufweist, an denen der eingebrachte Tonruf- wandler zur Anlage gelangt.According to a preferred embodiment, the separate holder can be designed as an annular body and partially enclose the ringer with a raised edge region, furthermore latching hooks are provided on the holder which reach through openings arranged in webs on the ringer, and furthermore the holder Its ring surface facing away from the latching hook has a plurality of spacers and, in the base region, has a plurality of spring tabs projecting into the interior of the body, against which the inserted ringer transducer comes to rest.
Die Verbindung des Tonrufwandlers mit dem Halter kann somit in einfacher Weise mittels einer Rastverbindung erfolgen, wo¬ bei der Tonrufwandler mit einer seiner Flächen an den nachge¬ benden Federlappen zur Anlage gelangt. Ferner weist der Hal¬ ter an seiner den Rasthaken entgegengesetzten Ringfläche meh- rere Abstandshalter auf, die seine beabstandete Befestigung auf einer Baugruppen aufweisenden Leiterplatte gestatten, so daß die unterhalb des Tonrufwandler bzw. des Halters befind- liehe Fläche auf der Leiterplatte freibleibt und zum Aufbrin¬ gen weiterer elektrischer oder elektronischer Bauteile ver¬ wendet werden kann.The ringing transducer can thus be connected to the holder in a simple manner by means of a snap-in connection, the ringing transducer coming into contact with one of its surfaces on the resilient spring tab. Furthermore, on its ring surface opposite the latching hook, the holder has a plurality of spacers which permit its spaced fastening on a printed circuit board which has assemblies, so that those located below the ringing transducer or the holder The surface on the circuit board remains free and can be used to apply further electrical or electronic components.
Dabei können die Rasthaken innerhalb von im Randbereich des Halters angeordneten Ausschnitten vorgesehen sein und paral¬ lel zum Randbereich verlaufen. Die Ausschnitte dienen dabei zur Aufnahme der am Tonrufwandler vorgesehenen und die Durch¬ brüche enthaltenden Stege.The latching hooks can be provided within cutouts arranged in the edge region of the holder and can run parallel to the edge region. The cutouts serve to accommodate the webs provided on the ringer and containing the openings.
Ferner können in den Endbereichen der Abstandshalter Klemm¬ dome vorgesehen sein, die auf ihrem Umfang angeordnete und in ihrer Längsrichtung verlaufende Rippen besitzen, wobei die Klemmdome in Bohrungen einer Leiterplatte einsteckbar sind. Der Durchmesser der mit den Rippen versehenen Klemmdome ist dabei etwas größer als die lichte Weite der in der Leiter¬ platte vorgesehenen Bohrungen, so daß beim Einstecken der Klemmdome in die Bohrungen eine leichte Verformung der Rippen erfolgt und ein Preßsitz der Halterung auf der Leiterplatte erzielt wird. Eine endgültige Festlegung des den Tonrufwand¬ ler aufnehmenden Halters in dem Kommunikationsendgerät wird dadurch erreicht, daß ein Gehäuseteil zur Aufnahme der Lei¬ terplatte mit dem aufgesteckten und gehalterten Tonrufwandler ' dient, während das andere Gehäuseteil im zusammengebauten Zu- stand des Kommunikationsendgerätes eine in der Fluchtlinie mit dem in der Halterung befindlichen Tonrufwandler liegende ringförmige und dem Durchmesser des Tonrufwandlers in etwa entsprechende Aufnahme besitzt, die in ihrem Innenraum meh¬ rere Anschlagrippen besitzt. Im zusammengefügten Zustand der beiden Gehäuseteile erfolgt eine Zentrierung des TonrufWand¬ lers durch die am Gehäuseteil vorgesehene ringförmige und den Tonrufwandler außen umfassende Aufnahme. Diese Aufnahme be¬ sitzt in ihrem Innenraum mehrere Anschlagrippen, die an der den Federlappen abgewandten Fläche des Tonrufwandlers zur An- läge gelangen. Dabei werden die Federlappen am Halter leicht verformt und die Rastverbindung zwischen dem Tonrufwandler und dem Halter entlastet, so daß dadurch geringfügige Ferti- gungstoleranzen bei der Herstellung der Gehäuseteile bzw. des Halters in einfacher Weise ausgeglichen werden können. Der Halter wird somit zwischen der Leiterplatte, mit der er über die Klemmdome seiner Abstandshalter und der ringförmigen Auf- nähme am anderen Gehäuseteil, die mit den Anschlagrippen auf den Tonrufwandler drückt, lagerichtig geklemmt gehalten, ohne daß es zusätzlicher Befestigungsteile bedarf.Furthermore, in the end regions of the spacers, clamping domes can be provided which have ribs arranged on their circumference and running in their longitudinal direction, the clamping domes being insertable into bores in a printed circuit board. The diameter of the clamping domes provided with the ribs is somewhat larger than the inside width of the bores provided in the printed circuit board, so that when the clamping domes are inserted into the bores there is a slight deformation of the ribs and an interference fit of the holder on the printed circuit board is achieved . A final fixing of the holder receiving the tone call transducer in the communication terminal is achieved in that one housing part serves to receive the circuit board with the attached and held tone call transducer, while the other housing part in the assembled state of the communication terminal is in the line of alignment with the ringing transducer located in the holder, which is in the form of a ring and approximately corresponds to the diameter of the ringing transducer and has a plurality of stop ribs in its interior. In the assembled state of the two housing parts, the ringing transducer is centered by the annular receptacle provided on the housing part and encompassing the ringing transducer on the outside. In its interior, this receptacle has a plurality of stop ribs which come to rest on the surface of the ringing transducer facing away from the spring tab. The spring tabs on the holder are slightly deformed and the locking connection between the ringing transducer and the holder is relieved, so that slight tolerances in the manufacture of the housing parts or the holder can be compensated in a simple manner. The holder is thus held in the correct position between the circuit board with which it is clamped via the clamping domes of its spacers and the ring-shaped receptacle on the other housing part, which presses on the ringing transducer with the stop ribs, without additional fastening parts being required.
Die Erfindung soll im folgenden anhand eines Ausführungsbei- spiels näher erläutert werden.The invention will be explained in more detail below on the basis of an exemplary embodiment.

Der in den Figuren dargestellte Halter 1 dient zur Aufnahme des Tonrufwandlers 2 und ist im wesentlichen ringförmig ge¬ staltet. Sein hochgezogener Randbereich 3 weist zwei sich ge¬ genüberliegende Ausschnitte 4 auf. Innerhalb dieser Aus- schnitte 4 ist jeweils ein parallel zum Randbereich 3 verlau¬ fender Rasthaken 5 vorgesehen, der einstückig mit dem Halter 1 verbunden ist. Ferner besitzt der Halter 1 im Basisbereich 3 in dem Innenraum des ringförmigen Körpers hineinragende Fe¬ derlappen 6.FIG. 7 shows a housing part serving to fix the ringer in a perspective view rotated by 180 °. The holder 1 shown in the figures is used to hold the ringing transducer 2 and is essentially ring-shaped. Its raised edge area 3 has two mutually opposite cutouts 4. Within these cutouts 4 there is in each case a latching hook 5 running parallel to the edge region 3, which is connected in one piece to the holder 1. Furthermore, the holder 1 in the base region 3 has spring tabs 6 projecting into the interior of the annular body.
Wie die Figur 2 zeigt, sind auf der Unterseite des ringförmi¬ gen Körpers drei Abstandshalter 7 einstückig mit dem Halter 1 verbunden. Zwei dieser Abstandshalter 7 besitzen in ihrem freien Endbereich Klemmdome 8, auf deren Verwendungszweck später eingegangen werden soll. Diese Klemmdome sind, wie die Figur 3 erkennen läßt, mit mehreren Rippen 9 dreieckförmigen Querschnitts auf ihrem Umfang versehen, wobei die Rippen in ihrer Längsrichtung verlaufen.As FIG. 2 shows, three spacers 7 are integrally connected to the holder 1 on the underside of the ring-shaped body. Two of these spacers 7 have clamping domes 8 in their free end area, the purpose of which will be discussed later. As can be seen in FIG. 3, these clamping domes are provided with a plurality of ribs 9 of triangular cross-section on their circumference, the ribs running in their longitudinal direction.
Figur 4 zeigt den Tonrufwandler 2 vor seinem Einbringen in den Halter 1. Dabei ist die Einsteckrichtung durch den Pfeil A angedeutet. Zu seiner Arretierung innerhalb des Halters 1 besitzt der Tonrufwandler 2 zwei sich gegenüberliegende und ' einstückig mit ihm verbundene Stege 10, die mit Durchbrüchen 11 versehen sind. Beim Einbringen des Tonrufwandlers in den Halter hintergreifen die Rasthaken 5 am Halter 1 diese Durch¬ brüche 11 an dem Tonrufwandler. In diesem Zustand liegen die Federlappen 6 unter leichter Vorspannung an dem in der Bild¬ ebene unten befindlichen Bodenbereich des Tonrufwandlers 2 an.FIG. 4 shows the ringer 2 before it is inserted into the holder 1. The direction of insertion is indicated by the arrow A. To lock it in the holder 1, the ringer 2 has two opposite and 'integrally connected to it webs 10 which are provided with openings 11. When the ringer is inserted into the holder, the latching hooks 5 on the holder 1 engage these openings 11 on the ringer. In this state, the spring tabs 6 bear against the bottom area of the ringing transducer 2, which is located at the bottom in the image plane, with a slight prestress.
In der Figur 5 ist die Befestigung des in den Halter 1 einge¬ brachten Tonrufwandlers 2 auf einer Leiterplatte 12 darge¬ stellt. Da diese in einem Fernsprechgerät zum Einsatz gelan- gende Leiterplatte 12 eine Baugruppe 13 besitzt, in deren Randbereich der Tonrufwandler aus Platzgründen untergebracht werden muß, sind am Tonrufwandler 2 Abstandshalter 7 angeord- net, die jeweils eine derartige Länge besitzen, daß der Ton¬ rufwandler 2 mit einem Teil seiner Fläche den Randbereich der Baugruppe geringfügig überragt oder auf ihm zu liegen kommt. Zur Fixierung des Halters 1 mit dem Tonrufwandler 2 auf der Leiterplatte 12 weist diese zwei Bohrungen 14 auf, in die je¬ weils die Klemmdome 8 der Abstandshalter 7 des Halters 1 ein¬ gedrückt werden. Dabei verformen sich die an den Klemmdomen 8 angeformten Rippen 9 geringfügig, so daß ein sicherer Pre߬ sitz des jeweiligen Klemmdomes 8 innerhalb der Bohrung 14 ge- währleistet ist. Der dritte keinen Klemmdom aufweisende Ab¬ standshalter 7 liegt dabei mit seinem freien Endbereich auf der Oberfläche der Leiterplatte 12 auf.FIG. 5 shows the attachment of the ringer 2 inserted into the holder 1 on a printed circuit board 12. Since this circuit board 12 used in a telephone set has an assembly 13 in the edge region of which the ringer must be accommodated for reasons of space, 2 spacers 7 are arranged on the ringer. net, each of such a length that the Ton¬ call transducer 2 with a part of its surface slightly overhangs the edge area of the assembly or comes to rest on it. To fix the holder 1 with the ringing transducer 2 on the printed circuit board 12, the latter has two bores 14 into which the clamping domes 8 of the spacers 7 of the holder 1 are pressed. The ribs 9 formed on the clamping domes 8 deform slightly, so that a secure press fit of the respective clamping domes 8 within the bore 14 is ensured. The third spacer 7, which does not have a clamping dome, lies with its free end region on the surface of the printed circuit board 12.
In den Figuren 6 und 7 ist die endgültige Lagesicherung des Halters mit dem Tonrufwandler zwischen den Gehäuseteilen 15 und 16 eines Fernsprechgerätes, z . B. eines schnurlosen Tele¬ fons gezeigt. Dabei nimmt das Gehäuseteil 15 die Leiterplatte 12 mit dem Halter 1 auf, während das Gehäuseteil 16 auf das Gehäuseteil 15 aufgesetzt und mit diesem verbunden wird.In Figures 6 and 7, the final position securing of the holder with the ringer between the housing parts 15 and 16 of a telephone set, for. B. a cordless phone is shown. The housing part 15 receives the printed circuit board 12 with the holder 1, while the housing part 16 is placed on the housing part 15 and connected to it.
Figur 7 gibt das Gehäuseteil 16 in einer um 180° gedrehten Lage wieder. Dieses Gehäuseteil 16 weist eine mit dem Halter 1 und dem eingebrachten Tonrufwandler 2 im zusammengebauten Zustand des Fernsprechgerätes in einer Fluchtlinie liegende ringförmige Aufnahme 17 auf, die zumindest zwei in ihrem In¬ nenbereich angeordnete Anschlagrippen besitzt. Im zusammenge¬ fügten Zustand der beiden Gehäuseteile 15 und 16 drücken die Anschlagrippen auf die in der Bildebene oben liegende Ober¬ fläche des Tonrufwandlers 2. Dadurch geben wieder die Feder- läppen 6 am Halter nach, so daß die Rasthaken des Halters 1 entlastet werden. Aufgrund der Fasung 19 der in der Bildebene oben liegenden Oberfläche des Tonrufwandlers wird dieser in¬ nerhalb der ringförmigen Aufnahme am Gehäuseteil 16 sicher geführt und zentriert. FIG. 7 shows the housing part 16 in a position rotated by 180 °. This housing part 16 has an annular receptacle 17 which is in alignment with the holder 1 and the inserted ringer 2 in the assembled state of the telephone set and which has at least two stop ribs arranged in its inner region. When the two housing parts 15 and 16 are in the assembled state, the stop ribs press on the surface of the ringing transducer 2 located above in the picture plane. As a result, the spring lugs 6 on the holder give in again, so that the latching hooks of the holder 1 are relieved. Due to the chamfer 19 of the surface of the ringing transducer lying at the top in the image plane, it is securely guided and centered within the annular receptacle on the housing part 16.
