Abstract

The antenna connector (7) of a car radio set is inserted into a plastic rectangular box (2), for security, in which box the cable guide is also located and which has an S-shaped plastic snap element (3) on each of its two longitudinal ends, which element engages over an edge (6) on the set by means of a long limb (4) having a mating hook (5). <IMAGE>

Description

Die Erfidnungbezieht sich auf eine Arretiervorrichtung für ei­nen Stecker insbesondere einen Koaxialstecker in einem Gerät der Nachrichtentechnik.The invention relates to a locking device for a connector, in particular a coaxial connector in a telecommunications device.

Bei solchen Nachrichtengeräten, insbesondere für den Mobilfunk, wird gefordert, daß vor allem Koaxialantennenstecker gegen Her­ausfallen bei Erschütterungen im Betrieb gesichert werden.In such communication devices, especially for mobile radio, it is required that especially coaxial antenna plugs are secured against falling out during vibrations during operation.

Der Erfindung liegt die Aufgabe zugrunde, hierfür eine günstige Lösung anzugeben.The invention has for its object to provide a cheap solution for this.

Erfindungsgemäß wird dies dadurch erreicht, daß der Stecker in einen länglichen Kunststoffquader eingesetzt ist, der an sei­nen beiden Längsenden je ein im Querschnitt S-förmig gebogenes Schnappelement trägt, dessen gegen das Gerät zu weisender Schen­kel über die Steckebene hinaus verlängert ist und am Ende mit einem Widerhaken versehen ist, mit dem er im Arretierungsfall hinter eine überhöhte Kante am Gerät greift und den Stecker festhält.According to the invention this is achieved in that the plug is inserted into an elongated plastic cuboid, which carries at its two longitudinal ends a snap element which is bent in an S-shaped cross-section, the leg of which pointing towards the device is extended beyond the plug-in level and ends with a Barb is provided, with which it engages behind a raised edge on the device in the event of locking and holds the plug.

Weitere vorteilhafte Ausbildungen der Erfindungfinden sich in den Unteransprüchen.Further advantageous developments of the invention can be found in the subclaims.

Nachstehend wird die Erfindung anhand eines in der Figur darge­stellten Ausführungsbeispiels naher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the figure.

Die Figur zeigt ein solches Funkgerät 1, das mit einem Antennen­stecker in Form einer Buchse 12 versehen ist. In diese Buchse wird ein Antennenstecker 7 eingesteckt, der in einem längli­chen Kunststoffquader 2 eingebettet ist. Der Stecker wird vor­zugsweise mit Spiel in einen Durchbruch des Quaders einge­setzt und durch einen Federring auf der Steckseite gesichert.The figure shows such a radio 1, which is provided with an antenna plug in the form of a socket 12. An antenna plug 7 is inserted into this socket and is embedded in an elongated plastic cuboid 2. The plug is preferably inserted with play into an opening in the cuboid and secured by a spring ring on the plug side.

An den Längsenden dieses Kunststoffquaders ist je ein S-förmig gebogenes Schnappelement 3 vorgesehen. Dieses S-förmige Schnapp­element hat auf der Geräteseite einen seit über die Steckebene hinaus verlängerten Schenkel 4, der am Ende mit einem Widerha­ken 5 versehen ist. Der Widerhaken hat frontseitig eine gefaste Kante, so daß er beim Aufstecken des Kunststoffkorpers auf das Gerät 1 über eine Kante 6 am Gerät gleiten kann und danach hin­ter diese Kante greift. Der Stecker ist auf diese Weise gegen Herausfallen gesichert. Der Bereich um die Kante kann natürlich auch als Nut ausgebildet sein.An S-shaped snap element 3 is provided on the longitudinal ends of this plastic cuboid. This S-shaped snap element has on the device side a leg 4 which has been extended beyond the plug-in level and which is provided at the end with a barb 5. The barb has a chamfered edge on the front so that when the plastic body is attached to the device 1 it can slide over an edge 6 on the device and then reaches behind this edge. In this way, the plug is secured against falling out. The area around the edge can of course also be designed as a groove.

Zur Aufhebung der Arretierung hat der längere Schenkel 4 in Abzugsrichtung außen einen geriffelten Bereich 14, der als Handgriff dient. Wird auf diese Bereiche gegen innen zu ge­drückt, so biegt sich der Innenbogen 11 des S-Körpers durch und die Widerhaken springen aus der Fassung, weil sich die­ses Ende des längeren Schenkels nach außen neigt. Es ist da­durch auf einfache Weise eine Entriegelung möglich.To release the lock, the longer leg 4 has a corrugated area 14 in the pull-off direction, which serves as a handle. If you press towards these areas inwards, the inner arch 11 of the S-body bends and the barbs jump out of the socket because this end of the longer leg tilts outwards. Unlocking is thus possible in a simple manner.

Um gleichzeitig das Antennenkabel 8 gegen Zug und Beschädigung am Stecker zu entlasten, ist es zunächst in einer Längsrille 13 des Kunststoffkörpers geführt. Gegen das Ausführungsende zu ist es mit einer Schelle 9 gesichert, die im einfachsten Fall aus einem angegossenen Kunststofflappen besteht, der gegen das Kabel zu abgebogen und durch Einschnappen oder mittels ei­ner zusätzlichen Schraube 10 gegen Lösen gesichert wird.In order to simultaneously relieve the antenna cable 8 against tension and damage to the plug, it is first guided in a longitudinal groove 13 in the plastic body. Towards the end of the execution it is secured with a clamp 9, which in the simplest case consists of a molded-on plastic tab which is bent against the cable and secured by snapping or by means of an additional screw 10 against loosening.
