Abstract

For locking the multipin plug or socket strip (14) which is to be connected to a radio set (10), a tong-shaped snap-on device (1) is proposed which retains the plug fixedly on the housing (10) when it is locked. The security device is easily detachable. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Sicherungsvorrichtung für eine Stecker- bzw. Buchsenleiste mit einem angeschlossenen flexiblen Kabel, wie z.B. aus EP-A- 48085 bekannt.The invention relates to a securing device for a plug or socket strip with a connected flexible cable, such as known from EP-A-48085.

Solche Sicherungsvorrichtungen sind insbesondere dann erforderlich, wenn das Gerät ortsbeweglich sein soll und häufiger Stekkerwechsel auf einfache Weise ermöglicht werden soll.Such safety devices are particularly necessary if the device is to be portable and frequent plug changes are to be made possible in a simple manner.

Der Erfindung liegt die Aufgabe zugrunde, für solche Fälle auf einfache Weise Abhilfe gegen unerwünschtes Lösen zu schaffen.The object of the invention is to provide a simple remedy for undesired loosening in such cases.

Gemäß der Erfindung wird diese Aufgabe gelöst, idem die Stecker- bzw. Buchsenleisten in ein im Profil U-förmig gebogenes Blechteil, das mit seinen Innenschenkel an den Längsseiten der Leiste anliegt, eingesetzt und mit ihm vorzugsweise schraubbar verbunden ist und an jedem Ende des Blechteils ein Scharnier vorgesehen ist, das je einen in Profil L-förmigen Haken trägt, der an seinem zum zugehörigen Steckerstück im Gerät hinweisenden Schenkelende einen Widerhaken hat, mit dem er in eine nutförmige Vertiefung am Gerät eingreift.According to the invention, this object is achieved in that the plug or socket strips are inserted into a sheet metal part which is bent in a U-shaped profile and rests with its inner legs on the long sides of the strip and is preferably screw-connected to it and at each end of the sheet metal part a hinge is provided, each carrying a profile L-shaped hook, which has a barb at its end pointing to the associated plug in the device, with which it engages in a groove-shaped recess on the device.

Vorteilhafte Ausgestaltungen der Erfindung finden sich in den Unteransprüchen.Advantageous embodiments of the invention can be found in the subclaims.

Nachstehend wird die Erfindung anhand eines in den Figuren dargestellten Ausführungsbeispiels näher erläutert.

Die Figur 1
zeigt den Teil eines Funkgerätes mit in Explosionsdarstellung gezeigtem anzuschließendem Stecker.
Die Figur 2
zeigt den Stecker mit Sicherungsvorrichtung.
Die Figur 3
zeigt die Sicherung im einzelnen.
Die Figur 4
zeigt schließlich die Sicherungsvorrichtung im eingeschnappten Zustand.
The invention is explained in more detail below on the basis of an exemplary embodiment shown in the figures.
Figure 1
shows the part of a radio with an exploded view of the connector to be connected.
Figure 2
shows the connector with safety device.
Figure 3

Figure 4
finally shows the safety device in the snapped state.

Bei Funkgeräten werden häufig sogenannte D-Substecker verwendet, bei denen eine größere Anzahl von Steckerstiften mit entsprechenden Buchsenleisten und vice versa mit dem Gerät verbunden werden müssen. Besonders für transportablen Betrieb ist dabei eine Sicherung des Steckers gegen Herausfallen auch bei starken Erschütterungen erforderlich. Die mehrpolige Stecker- bzw. Buchsenleiste 14 wird hierzu am Blechteil 1 mittels Schrauben 15 verbunden, das für den eigentlichen Stecker einen Durchbruch 19 hat. Das Blechteil ist im Profil U-förmig mit schalen Längsschenkeln 20. Diese Längsschenkel liegen an den Seitenwänden des Steckergehäuses 16 an. Für die Schrauben 15 sind beidseits des Gehäuses in Längsrichtung betrachtet Gewindelöcher 6 im Blechteil 1 vorgesehen. Die Schenkelenden in Längsrichtung betrachtet sind zu Ösen 7 geformt. Zwischen diese Ösen ist kippbar je ein L-förmiger Haken 2 eingelegt und zwar so, daß der eine Schenkel 3a außerhalb des Blechs zu liegen kommt. Der Verbindungsbereich der Schenkel 4 ist mit einer Bohrung oder einem Durchbruch 8 versehen, durch den über die Ösen ein Bolzen 5 gedrückt ist, so daß ein Scharnier entsteht. Die äußeren Schenkel 3 umschließen das Gerät 10 selbst und haben am Ende als Niederhaken 9 ausgebildete Abkantungen. Diese Abkantungen greifen im Befestigungsfall in nutförmige Vertiefungen 21 ein. Um die Arretierung zu verbessern, ist zwischen die Schenkel 3, 3a, die etwa rechtwinkelig (vorzugsweise etwas größer als 90°) zueinander stehen, eine flexible Zunge 11 schräg stehend angeordnet. Diese Zunge soll beim Aufdrücken auf die Seitenwand 22 des Gerätes dafür sorgen, daß die Widerhaken 9 fest in die Nut 21 gedrückt werden. Sie ist dazu gegen den Schenkel 3a und das Gerät hin leicht geneigt. Die Zunge 11 hat am Ende wieder eine hakenförmige Abkantung 12 mittels derer sie letztendlich an der Seitenwand oder einer Vertiefung darin drückt. Am Schenkel 3 ist eine zusätzliche Versteifungsrippe 13 angebracht.So-called D-sub plugs are often used in radio devices, in which a large number of plug pins must be connected to the corresponding socket strips and vice versa with the device. In particular for transportable operation, the plug must be secured against falling out even in the event of strong vibrations. For this purpose, the multipole plug or socket strip 14 is connected to the sheet metal part 1 by means of screws 15, which has an opening 19 for the actual plug. The sheet metal part is U-shaped in profile with shell-shaped longitudinal legs 20. These longitudinal legs abut the side walls of the connector housing 16. For the screws 15, threaded holes 6 are provided in the sheet metal part 1 on both sides of the housing in the longitudinal direction. The leg ends, viewed in the longitudinal direction, are shaped into eyelets 7. Between these eyelets, an L-shaped hook 2 is inserted in such a way that one leg 3a comes to rest outside the sheet. The connecting area of the legs 4 is provided with a bore or an opening 8 through which a bolt 5 is pressed over the eyelets, so that a hinge is formed. The outer legs 3 enclose the device 10 itself and, at the end, have folds 9 designed as a hook. These folds engage in groove-shaped depressions 21 in the case of attachment. In order to improve the locking, a flexible tongue 11 is arranged at an angle between the legs 3, 3a, which are approximately at right angles (preferably somewhat larger than 90 °) to one another. This tongue should ensure when pressed onto the side wall 22 of the device that the barbs 9 are pressed firmly into the groove 21. It is slightly inclined towards the leg 3a and the device. At the end, the tongue 11 again has a hook-shaped fold 12 by means of which it ultimately presses against the side wall or a recess therein. An additional stiffening rib 13 is attached to the leg 3.

Wird in Arretierungsstellung gegen die Außenschenkel 3a in Richtung Stecker gedrückt, so löst sich die Verbindung und der Stecker kann abgezogen werden. Stecker und Sicherung bilden so eine Einheit.If, in the locking position, the outer leg 3a is pressed in the direction of the plug, the connection is released and the plug can be removed. The plug and fuse form one unit.

Das Steckergehäuse 16 hat eine Zugentlastung 18 für die Kabel 17.The plug housing 16 has a strain relief 18 for the cables 17th

Es ist auf diese Weise eine einfache Steckersicherung verwirklicht, die auch jederzeit nachträglich an solchen Stekkergehäusen montiert werden kann, wozu nur zwei Rändelschrauben 15 notwendig sind.In this way, a simple plug lock is implemented, which can also be retrofitted to such plug housings at any time, for which purpose only two knurled screws 15 are necessary.
