Gegenstand der Neuerung 1st eine Vorrichtung zur Zugentlastung von elektrischen Kabeln in einem aus zwei Halbschalen bestehenden Steckergehäuse. The subject of the innovation is a device for strain relief of electrical cables in a connector housing consisting of two half-shells.
Bei Steckern bzw. Steckerleisten, an die elektrische Leitungen geführt werden, ist as erforderlich, die elektrischen Leitungen am Stecker bzw. an der Steckerleiste zu befestigen, damit beim Ziehen des Steckers die elektrischen Leitungen durch übermäßige Zugbeanspruchungen nicht beschädigt werden. Die Zugentlastung In the case of plugs or connector strips to which electrical lines are routed, it is necessary to attach the electrical lines to the plug or to the connector strip so that the electrical lines are not damaged by excessive tensile stress when the plug is pulled. The strain relief
dient jedoch auch dem Schutz der angeschlossenen Kontakte, die
ansonsten bei Bewegungen der Leitungen beschädigt werden bzw.
die Kontaktgabe verschlechtert wird. Dafür ist es bekannt, das Kabel mit Leitungsschellen am Steckergehäuse zu fixieren. Diese
bekannte Vorrichtung hat jedoch den Nachteil, daß die Leitungsschellen relativ genau der Form und Größe des Kabels angepaßt
sein müssen. Bei verschiedenen Kabelgrößen, beispielsweise bei Flachband- oder Rundbandkabel,muß eine größere Anzahl von Kabelschellen
bereitgehalten werden. Es ist auch bekannt, das Kabel mit einem Bindgarn abzubinden bzw. das Aabel mit dem Bindgarn However, it also serves to protect the connected contacts, which would otherwise be damaged or damaged when the cables move.
the contact is worsened. To do this, it is known to fix the cable to the connector housing with cable clamps. However, this known device has the disadvantage that the cable clamps are adapted relatively precisely to the shape and size of the cable
must be. With different cable sizes, for example with ribbon or round ribbon cables, a larger number of cable clamps must be kept ready. It is also known to tie off the cable with a binding thread or the cable with the binding thread

Die Aufgabe wird gemäß der Neuerung dadurch gelöst, daß an der Innenseite der Halbschale des Steckers das Kabel auf einer gerieften Auflagefläche liegt, daß parallel zum Kabel in der Auflagefläche Schlitze ausgenommen sind, zwischen der.en das Kabel liegt, daß in die Schlitze ein an sich bekannter Kabelbinder gefädelt und um das Kabel gelegt ist und daß der zusammengezogene Kabelbinder das Kabel formschlüssig mit der Auflagefläche verbindet.The object is achieved according to the innovation in that at the Inside the half-shell of the plug, the cable lies on a grooved support surface that is parallel to the cable in the support surface Slots are excluded, between der.en the cable lies that a known cable tie is threaded into the slots and is placed around the cable and that the pulled-together cable tie connects the cable with the support surface in a form-fitting manner.
Die Neuerung hat den Vorteil, daß die Zugentlastung besonders einfach und kostengünstig mit einem an sich bekannten Kabelbinder erreicht wird. Der Kabelbinder besteht vorteilhaft aus elastischem Kunststoff und ist lösbar. Es wird eine besonders wirksame Zugentlastung erreicht, weil der Kabelbinder das Kabel formschlüssig mit der Auflagefläche verbindet. Die Zugentlastung wird bei allen Formen und Größen der Kabel, beispielsweise Flachband- oder ilundkabel, erreicht. Der Aufwand ist besonders gering, weil die geriefte Auflagefläche und die Schlitze bereits beim Spritzvorgang der Halbschalen des Steckergehäuses hergestellt werden und der Kabelbinder kostengünstig im Handel erhältlich ist. 20The innovation has the advantage that the strain relief is particularly simple and inexpensive with a cable tie known per se is achieved. The cable tie is advantageously made of elastic plastic and is detachable. It becomes a particularly effective strain relief achieved because the cable tie connects the cable positively to the support surface. The strain relief is common to all Shapes and sizes of the cables, for example flat or round cables, achieved. The effort is particularly low because the grooved contact surface and the slots are already used during the injection molding process the half-shells of the connector housing are made and the cable tie is inexpensive commercially available. 20th
Einzelheiten der Neuerung werden nachfolgend anhand eines in der Figur dargestellten vorteilhaften Ausführungsbeispiels erläutert.Details of the innovation are explained below with reference to an advantageous embodiment shown in the figure.
Die Figur zeigt einen Leitungsstecker für Flachband- oder Rundkabei. Der Leitungsstecker besteht aus den beiden aus Kunststoff bestehenden Halbschalen 1 und 2 des Steckergehäuses und der aufsetzbaren Steckkontaktleiste 3. Die Halbschalen haben eine seitliche öffnung, an der das Kabel eingeführt wird und an der sich die geriefte Auflagefläche 4 befindet. Am Beginn, am Ende und in der Mitte der Auflagefläche ist jeweils ein Schlitz 5, 6 und 7 in der Halbschale ausgenommen. Durch die Schlitze wird der aus elastischem Kunststoff bestehende Kabelbinder 8 eingefädelt. Dabei werden für das Flachbandkabel 9 die Schlitze 5 und 7 und für das Rundkabel 10 die Schlitze 5 und 6 oder 6 und 7 verwendet. Der Kabelbinder wird um das Kabel gelegt und festgezogen. Dadurch wird eine fcrmschlüssige Verbindung des Kabels mit der gerieften Auflagefläche 4 erreicht. Der Kabelbinder ist lösbar ausgebildet. Es können auch mehrere Kabel nebeneinander oder übereinander durchThe figure shows a cable connector for flat or round cables. The cable connector consists of the two plastic half-shells 1 and 2 of the connector housing and the attachable Plug-in contact strip 3. The half-shells have a side opening into which the cable is inserted and where the the grooved support surface 4 is located. At the beginning, at the end and in the middle of the support surface is a slot 5, 6 and 7 except in the half-shell. The cable tie 8 made of elastic plastic is threaded through the slots. Included the slots 5 and 7 are used for the ribbon cable 9 and the slots 5 and 6 or 6 and 7 are used for the round cable 10. The cable tie is placed around the cable and tightened. This creates an interlocking connection between the cable and the grooved Support surface 4 reached. The cable tie is detachable. You can also run several cables side by side or on top of each other

den Kabelbinder festgezogen werden. Die Kanten 11 der Schlitze, an denen der Kabelbinder anliegt, sind abgeschrägt bzw. abgerundet, damit ein großer Biegeradius des Kabelbinders erreicht wird und der Kabelbinder am Kabel fest anliegt. Es entstehen dadurch keine Zwischenräume zwischen Kabel und Kabelbinder. Nach dem Festziehen des Kabelbinders wird das vorstehende Ende abgetrennt und die zweite Halbschale auf die erste Halbschale aufgedrückt bzw. zusammengeschraubt.the cable tie must be tightened. The edges 11 of the slots on which the cable tie rests are beveled or rounded, so that a large bending radius of the cable tie is achieved and the cable tie rests firmly on the cable. It arises from it no gaps between cables and cable ties. After tightening the cable tie, the protruding end is cut off and the second half-shell pressed onto the first half-shell or screwed together.
Im dargestellten Ausführungsbeispiel sind die beiden Halbschalen gleich ausgebildet. Jede Halbschale hat zwei Offnungen, so daß wahlweise das Kabel auf der einen oder anderen Seite in den Stecker eingeführt werden kann. Der zweite nicht benutzte Eingang wird durch ein Plättchen 12 oder das Typenschild abgedeckt. Dadurch, daß die Halbschalen gleich ausgebildet sind, befinden sich die Auflagefläche und die Schlitze gegengleich auf der anderen Seite der Halbschale 2. Beim Einführen des Kabels von der anderen Seite her wird der Kabelbinder durch die Schlitze in der Halbschale 2 eingefädelt und festgezogen.In the illustrated embodiment, the two half-shells are designed the same. Each half-shell has two openings so that optionally the cable can be inserted into the connector on one side or the other. The second unused input is covered by a plate 12 or the nameplate. Due to the fact that the half-shells are formed the same, are the Support surface and the slots are opposite to each other on the other side of the half-shell 2. When inserting the cable from the other side the cable tie is threaded through the slots in the half-shell 2 and tightened.
