Description

Technisches GebietTechnical field

Die Erfindung befaßt sich mit der Ausbildung von Lötösenplatten von Lautsprechern, insbesondere mit der Verbindung von Lötösenplatte und Lautsprecher sowie mit der Sicherung von Lautsprecheranschlußkabeln.The invention is concerned with the formation of soldering eye plates of loudspeakers, in particular with the connection of soldering eye plates and loudspeakers, and with the securing of loudspeaker connection cables.

Stand der TechnikState of the art

Im allgemeinen erfolgt die Komplettierung von Lautsprechern dergestalt, daß die die Schwingspule des Lautsprechers kontaktierenden Lautsprecherlitzen von der Schwingspule zu einer am Lautsprecherkorb angesetzten Lötösenplatte geführt sind und dort mit in die Lötösenplatte eingesetzten Lötösen durch Lötung verbunden sind. Die Verbindung von Lötösenplatte und Lautsprecher ist gemäß dem Stand der Technik meist so realisiert, daß die Lötösenplatte mit dem Lautsprecherkorb mittels eines Niets verbunden ist. Diese Art der Verbindung ist aber im Hinblick auf eine rationale Fertigung nachteilig. Dies deshalb, weil vom Arbeitsablauf zunächst die Lötösenplatte von einem Werkzeug an dem Verbindungsort mit dem Korb gehalten werden muß und der Niet durch die Lötösenplatte und eine im Lautsprecherkorb angeordnete Öffung geführt werden muß bevor die Nietung ausgeführt wird.In general, the completion of loudspeakers takes place in such a way that the speaker strands contacting the voice coil of the speaker are guided from the voice coil to a soldering eye plate attached to the loudspeaker basket and are connected there by soldering to soldering eyes inserted into the soldering eye plate. The connection between the soldering eye plate and the loudspeaker is usually realized in accordance with the prior art in such a way that the soldering eye plate is connected to the loudspeaker basket by means of a rivet. This type of connection is disadvantageous in terms of rational production. This is because from the workflow, the soldering eye plate is first carried by a tool at the connection location the basket must be held and the rivet must be passed through the soldering eye plate and an opening arranged in the loudspeaker basket before the riveting is carried out.

Die Kontaktierung des Lautsprechers mit der Signalquelle ist meist so realisiert, daß eine Anschlußleitung mit den Lötösen verlötet ist. Auch ist es bekannt, die Lötösenplatte mit Steckzungen zu versehen, auf die Stecker, welche mit den Anschlußkörpern verbunden sind, aufgeschoben werden. Vor allem bei der Kontaktierung im erstgenannten Sinne, aber auch bei der Kontaktierung in der Steckverbindungstechnik kann es erforderlich sein, daß die Anschlußkabel gegen Zug entlastet sind. Dies gilt insbesondere dann, wenn die Lautsprecher bereits mit den verbundenen Anschlußkabeln zum Abnehmer geliefert werden, denn in diesem Falle kann nicht ausgeschlossen werden, daß die schweren Lautsprecher nicht doch an den Anschlußkabeln transportiert werden. Die Folge ist, daß bei dieser Behandlung der Lautsprecher die Anschlußkabel abreißen, wenn keine Zugentlastung vorhanden ist. Eine Möglichkeit Zugentlastung von Lautsprecheranschlußkabeln zu realisieren ist die Verwendung von sogenannten Kabelbindern, die beispielsweise das Anschlußkabel, nachdem es mit der Lötösenplatte verbunden ist, gegen das Magnetsystem pressen. Auch ist es bekannt, am Lautsprecherkorb eine vorstehende Lasche auszubilden, welche, wenn das Anschlußkabel zwischen Lasche und Lautsprecherkorb geführt ist, das Anschlußkabel gegen den Lautsprecherkorb drückt.The contacting of the loudspeaker with the signal source is usually realized in such a way that a connecting line is soldered to the soldering lugs. It is also known to provide the soldering eye plate with tongues onto which plugs which are connected to the connection bodies are pushed. Especially when contacting in the first sense, but also when making contact in the connector technology, it may be necessary that the connection cable is relieved against train. This applies in particular if the loudspeakers are already delivered to the customer with the connected connection cables, because in this case it cannot be ruled out that the heavy loudspeakers will not be transported on the connection cables. The result is that with this treatment of the loudspeakers, the connection cables tear off if there is no strain relief. One way of realizing strain relief for loudspeaker connection cables is the use of so-called cable ties which, for example, press the connection cable against the magnet system after it is connected to the soldering eye plate. It is also known to form a protruding tab on the loudspeaker basket, which, when the connecting cable is guided between the tab and the loudspeaker basket, presses the connecting cable against the loudspeaker basket.

Da die Anschlußkabel flexibel sind, ist es leicht einzusehen, daß die Realisierung der Zugentlastung gemäß dem Stand der Technik nur mit unverhältnismäßig großem Aufwand automatisierbar ist. Aus diesem Grunde wird die Zugentlastung auch meist in Handarbeit realisiert, nachdem die Verbindung des Anschlußkabels mit der Lötösenplatte ausgeführt ist.Since the connection cables are flexible, it is easy to see that the implementation of the strain relief according to the prior art is only disproportionately large Effort can be automated. For this reason, the strain relief is mostly realized by hand after the connection cable has been connected to the soldering eye plate.

Daher liegt der Erfindung die Aufgabe zugrunde, für Lautsprecherkörbe mit Lötösenplatten eine Zugentlastung für Lautsprecheranschlußkabel anzugeben, die in einfacher Weise automatisierbar hergestellt werden kann.The invention is therefore based on the object of specifying a strain relief for loudspeaker connection cables for loudspeaker baskets with soldering eye plates, which strain relief can be produced in a simple, automated manner.

Darstellung der ErfindungPresentation of the invention

Diese Aufgabe wird mit den Merkmalen gemäß Anspruch 1 gelöst.
Dadurch, daß der Sperriegel die Rasthaken der Lötösenplatte, welche hinter den Vorsprüngen des Lautsprecherkorbes verrastet sind, lagefixiert, wird ein Ausweichen der Rasthaken selbt bei Wirkung erheblicher Zugkräfte auf die Lötösenplatte ausgeschlossen, so daß die Lötösenplatte nicht mehr vom Lautsprecherkorb zerstörungsfrei getrennt werden kann.
Wird - wie angegeben - das von der Lötösenplatte zur Signalquelle führende Anschlußkabel zwischen der Lötösenplatte und dem Sperriegel eingequetscht, wird gleichzeitig auch eine Zugentlastung geschaffen, welche in sehr einfacher Weise automatisiert werden kann. Dies ist darauf zurückzuführen, daß durch die Kontaktierung des Anschlußkabels mit den Lötösen dieses ohnehin im Bereich der Lötösenplatte gehalten werden muß, so daß ohne erneutes Ergreifen des Kabels dieses allein durch das Aufstecken des Sperriegels in zugentlastender Weise gegen die Lötösenplatte gedrückt wird.
This object is achieved with the features according to claim 1.
Because the locking bolt fixes the locking hooks of the soldering eye plate, which are locked behind the projections of the loudspeaker basket, evasion of the locking hooks is ruled out even when considerable tensile forces are exerted on the soldering eye plate, so that the soldering eye plate can no longer be separated from the loudspeaker basket without being destroyed.
If - as stated - the connecting cable leading from the soldering eye plate to the signal source is squeezed between the soldering eye plate and the locking bolt, a strain relief is also created, which can be automated in a very simple manner. This is due to the fact that the contacting of the connecting cable with the soldering lugs has to be held in the area of the soldering eye plate anyway, so that the cable is pressed against the soldering eye plate in a strain-relieving manner simply by plugging in the locking bolt without having to grip the cable again.

Sind gemäß Anspruch 2 die Vorsprünge, hinter welchen die Rasthaken der Lötösenplatte im Verbindungsfalle von Lautsprecherkorb und Lötösenplatte verrastet sind, in zumindest einem der Stege des Lautsprecherkorbs angeordnet, so können diese Vorsprünge ohne zusätzlichen Arbeitsaufwand bei der Herstellung des Lautsprecherkorbes mit ausgebildet werden.If, according to claim 2, the projections, behind which the latching hooks of the soldering eye plate are locked in the connection case of the loudspeaker basket and the soldering eyelet plate, are arranged in at least one of the webs of the loudspeaker basket, these projections can be formed without additional work in the manufacture of the loudspeaker basket.

Wege zum Ausführen der ErfindungWays of Carrying Out the Invention

Die Erfindung soll nun anhand der Figuren näher erläutert werden.The invention will now be explained in more detail with reference to the figures.

Die in Figur 1 gezeigte Draufsicht zeigt eine Lötösenplatte 10, die mit einem Steg 11 eines Lautsprecherkorbes 12 verbunden ist. Der Querschnitt des Steges 11 ist in dem Bereich, in dem die Lötösenplatte 10 aufgesetzt ist, verengt ausgebildet. Wie die Figur 2 deutlich hervorhebt, ist die Lötösenplatte mit dem Steg 11 verrastet. Dazu sind an der Seite der Lötösenplatte 10, welche dem Steg 11 zugewandt ist, Rasthaken 13 ausgebildet, die, wenn die Lötösenplatte 10 mit dem Steg 11 verbunden ist, hinter den vom Stegprofil gebildeten Vorsprüngen 14 verrastet sind. Die Länge (L) der Rasthaken 13 entspricht der Länge des verengten Stegprofils. Dadurch ist sichergestellt, daß die Lötösenplatte 10 auch in den Pfeilrichtungen (P) unverschiebbar mit dem Steg 11 verbunden ist (Figur 1).The top view shown in FIG. 1 shows a soldering eye plate 10 which is connected to a web 11 of a loudspeaker basket 12. The cross section of the web 11 is narrowed in the area in which the soldering eye plate 10 is placed. As FIG. 2 clearly emphasizes, the soldering eye plate is locked with the web 11. For this purpose, latching hooks 13 are formed on the side of the solder eyelet plate 10 which faces the web 11 and, when the solder eyelet plate 10 is connected to the web 11, are locked behind the projections 14 formed by the web profile. The length (L) of the locking hook 13 corresponds to the length of the narrowed web profile. This ensures that the soldering eye plate 10 is connected to the web 11 so that it cannot move in the direction of the arrow (P) (FIG. 1).

Seitlich an der Lötösenplatte 10 sind die Lötösen 15 angesetzt. An diesen Lötösen 15 erfolgt später die Kontaktierung der Lautsprecherlitzen und der Anschlußkabel (nicht dargestellt). Beiderseits der Rasthaken 13 sind Öffnungen 16 in die Lötösenplatte 10 eingelassen. Diese Öffnungen 16 dienen dazu, die Schenkel 17 des Sperriegels 18 aufzunehmen.The soldering eyes 15 are attached to the side of the soldering eye plate 10. The speaker wires and the connecting cables (not shown) are later contacted at these soldering lugs 15. Openings 16 are let into the soldering eye plate 10 on both sides of the latching hooks 13. These openings 16 serve to receive the legs 17 of the locking bolt 18.

Diese Situation ist in Figur 3 näher dargestellt. Der Sperriegel 18 ist mit seinen beiden Schenkeln 17 in die Öffnungen 16 eingeschoben. Die Schenkel 17 sind ebenfalls rasthakenförmig ausgebildet und sind, wenn der Sperriegel 18 mit der Lötösenplatte 10 verbunden ist, an der Unterseite der Lötösenplatte 10 mit dieser verrastet. Die Baulänge der Schenkel 17 ist so bemessen, daß sie in etwa der Länge der Rasthaken 13 der Lötösenplatte 10 entspricht. Die Enden der Rasthaken 13 weisen auf der den Schenkeln 17 zugewandten Seite Ausformungen 19 auf, an denen die Schenkel 17, wenn sie ihre Endlage in der Lötösenplatte 10 gefunden haben, anliegen. Dies stellt sicher, daß bei Zugeinwirkungen (Z) beispielsweise auf die Lötösenplatte 10 die Rasthaken 13 nicht in Pfeilrichtung (R) ausweichen können und die Lötösenplatte 10 freigeben.This situation is shown in more detail in Figure 3. The locking bolt 18 is inserted with its two legs 17 into the openings 16. The legs 17 are also designed in the form of catch hooks and, when the locking bar 18 is connected to the soldering eye plate 10, are latched to the underside of the soldering eye plate 10. The overall length of the legs 17 is dimensioned such that it corresponds approximately to the length of the latching hook 13 of the soldering eye plate 10. The ends of the locking hooks 13 have, on the side facing the legs 17, formations 19 against which the legs 17 bear when they have found their end position in the soldering eye plate 10. This ensures that in the event of tensile influences (Z), for example on the soldering eye plate 10, the latching hooks 13 cannot deflect in the direction of the arrow (R) and release the soldering eye plate 10.

Die beiden Schenkel 17 des Sperriegels 18 sind über das Zwischenstück 20 miteinander verbunden. In dem in Figur 3 gezeigten Ausführungsbeispiel liegt dieses Zwischenstück 20, wenn der Sperriegel 18 seine Endposition in der Lötösenplatte 10 gefunden hat, direkt auf der Lötösenplatte 10 auf. Etwa mittig im Zwischenstück 20 ist ein Schlitz 21 eingelassen, in welchem das Anschlußkabel 22 eingelegt ist. Die Höhe des Schlitzes 21 ist so bemessen, daß bei eingelegtem Anschlußkabel 22, dieses Kabel 22 von dem Zwischenstück 20 gegen die Lötösenplatte 10 gedrückt wird, wenn der Sperriegel 18 seine Endposition in der Lötösenplatte 10 gefunden hat. Hierdurch wird eine wirksame Zugentlastung des Anschlußkabels 22 im Bereich der Lötösenplatte 10 erreicht.The two legs 17 of the locking bolt 18 are connected to one another via the intermediate piece 20. In the embodiment shown in Figure 3, this intermediate piece 20, when the locking bar 18 has found its end position in the soldering eye plate 10, directly on the Soldering eye plate 10 on. A slot 21, in which the connecting cable 22 is inserted, is let into the middle of the intermediate piece 20. The height of the slot 21 is dimensioned such that when the connecting cable 22 is inserted, this cable 22 is pressed by the intermediate piece 20 against the soldering eye plate 10 when the locking bar 18 has found its end position in the soldering eye plate 10. In this way, an effective strain relief of the connecting cable 22 is achieved in the area of the soldering eye plate 10.

Es sei darauf hingewiesen, daß der in Figur 3 gezeigte Sperriegel 18 auch ohne eingelegtes Anschlußkabel 22 verwendet werden kann. In diesem Fall hat der Sperriegel 18 nur die Funktion, die Lagefixierung der Rasthaken 13 am Steg 11 sicherzustellen.It should be pointed out that the locking bolt 18 shown in FIG. 3 can also be used without an inserted connecting cable 22. In this case, the locking bolt 18 only has the function of ensuring that the locking hooks 13 are fixed in position on the web 11.

In Figur 4 ist eine gegenüber Figur 3 abgeänderte Formgebung der Lötösenplatte 10 mit eingestecktem und verrastetem Sperriegel 18 gezeigt.FIG. 4 shows a modified shape of the soldering eye plate 10 with respect to FIG. 3, with the locking bolt 18 inserted and locked.

Die Lötösenplatte 10 weist einen Dorn auf, der durch eine Öffnung im Steg 11 eingeschoben ist. Dieser Dorn erleichtert das lagegenaue Verbinden von Lötösenplatte 10 und Steg 11. Sobald die Lötösenplatte 10 auf dem Steg 11 aufliegt (wie in Figur 4 dargestellt), verrasten die an der Lötösenplatte 10 angeordneten Rasthaken 13 hinter den durch den Steg 11 gebildeten Vorsprüngen 14. Ist sodann die Verbindung des Anschlußkabels 22 mit den Lötösen (in Figur 4 nicht dargestellt) hergestellt, kann das Anschlußkabel 22 dabei auf dem Auflagebett 23 aufgelegt sein. Dies ist besonders vorteilhaft, weil damit zum Verbinden das Anschlußkabel 22 mit kurzem Abstand zu den Lötösen (in Figur 4 nicht dargestellt) gehaltert werden kann. Nach Beendigung des Lötvorgangs wird dann der Sperriegel 18 auf die Lötösenplatte 10 aufgeschoben und verrastet. Dazu werden die glatten Schenkel 17 des Sperriegels 18 durch die Öffnungen 16 der Lötösenplatte 10 geschoben. Im Gegensatz zu der Ausbildung gemäß Figur 3 sind in Figur 4 die Schenkel 17 des Sperriegels 18 glattwandig ausgebildet. Diese glattwandigen Schenkel 17 haben in dem in Figur 4 dargestellten Ausführungsbeispiel allein die Aufgabe, die Rasthaken 13 an den Ausformungen 19 lagezufixieren, so daß ein Ausrasten der Rasthaken 13 unter Zugeinwirkung ausgeschlossen ist. Die Verbindung von Lötösenplatte 10 und Sperriegel 18 erfolgt über die eigenständig am Sperriegel 18 ausgebildeten Rasthaken 24 (gestrichelt dargestellt). Diese Rasthaken 24 verrasten hinter an der Lötösenplatte 10 angeordneten Nase 25, sobald der Sperriegel 18 seine Endposition auf der Lötösenplatte 10 gefunden hat. Im Kopf des Sperriegels 18 ist ein Stempel 26 angeordnet. Dieser Stempel 26 drückt, wenn die Rasthaken 24 hinter den Nasen 25 eingeklinkt sind, auf das auf der Auflageplatte 23 aufliegende Anschlußkabel 22. Damit ist eine einfach ausführbare und wirksame Zugentlastung für das Kabel 22 hergestellt.The soldering eye plate 10 has a mandrel which is inserted through an opening in the web 11. This mandrel facilitates the precise connection of the soldering eye plate 10 and the web 11. As soon as the soldering eye plate 10 rests on the web 11 (as shown in FIG. 4), the latching hooks 13 arranged on the soldering eye plate 10 snap behind the projections 14 formed by the web 11 then the connection of the connection cable 22 with the soldering lugs (not shown in FIG. 4) is established, the connection cable 22 can be placed on the support bed 23. This is particularly advantageous because it allows the connection cable 22 to be held at a short distance from the soldering lugs (not shown in FIG. 4) for connection. After completing the soldering process, the Locking bolt 18 pushed onto the soldering eye plate 10 and locked. For this purpose, the smooth legs 17 of the locking bolt 18 are pushed through the openings 16 of the soldering eye plate 10. In contrast to the embodiment according to FIG. 3, the legs 17 of the locking bolt 18 are smooth-walled in FIG. In the exemplary embodiment shown in FIG. 4, these smooth-walled legs 17 have the sole task of fixing the locking hooks 13 to the formations 19, so that the locking hooks 13 cannot be disengaged under the action of a pull. The connection of the soldering eye plate 10 and the locking bar 18 takes place via the locking hooks 24 which are formed independently on the locking bar 18 (shown in broken lines). These latching hooks 24 latch behind the nose 25 arranged on the soldering eye plate 10 as soon as the locking bar 18 has found its end position on the soldering eye plate 10. A stamp 26 is arranged in the head of the locking bolt 18. This stamp 26 presses, when the latching hooks 24 are latched behind the lugs 25, onto the connection cable 22 resting on the support plate 23. This provides a simple and effective strain relief for the cable 22.

In Figur 5 ist ein Einbaubeispiel für eine Lötösenplatte 10 mit aufgesetztem Sperriegel 18 gemäß Figur 4 gezeigt. Die Lötösenplatte 10 und der Sperriegel 18 sind als Einheit seitlich an einem Steg 11 des Lautsprecherkorbes 12 angesetzt. Deutlich ist aus Figur 5 entnehmbar, daß das Anschlußkabel 22 durch die besondere Formgebung der Lötösenplatte 10 und des Sperriegels 18 in meanderförmiger Weise zwischen den beiden zuvorbenannten Bauteilen eingeklemmt ist. Durch diese Art der Ausgestaltung von Lötösenplatte 10 und Sperriegel 18 ist eine besonders wirksame Zugentlastung des Anschlußkabels 22 realisiert.FIG. 5 shows an installation example for a soldering eye plate 10 with a locking bolt 18 according to FIG. 4 attached. The soldering eye plate 10 and the locking bar 18 are laterally attached as a unit to a web 11 of the speaker basket 12. It can be clearly seen from FIG. 5 that the connecting cable 22 is clamped in a meandering manner between the two aforementioned components due to the special shape of the soldering eye plate 10 and the locking bolt 18. This type of design of the soldering eye plate 10 and the locking bolt 18 provides a particularly effective strain relief for the connecting cable 22.
