Description
Stecker mit Zugentlastung. Für längsgeteilte elektrische Stecker, deren Griffkörper aus zwei gleichartigen isolierenden Hälften besteht, die lösbar zusammenge schraubt sind, sind Zugentlastungsvorrich- tungen für die einzuführende Leitungs schnur in Form zweiteiliger Schellen bekannt, welche entweder lose im Innern des Stecker körpers liegen, oder in ihm durch Einpressen oder Verschrauben befestigt sind.
Während sich das lose Einlegen der Schelle als unpraktisch erwiesen hat, da man beim Öffnen des Steckers, das heisst beim Auseinanderschrauben der Griffkörperhälften, die Schelle leicht verliert, ist die andere Art der Befestigung, zum Beispiel durch Ver schraubung oder Einpressen, in der Herstel lung zu teuer.
Um nun die Zugentlastungsscbelle bei ge öffnetem Stecker auch ohne besondere Be festigungselemente gegen das Verlieren zu schützen, wird gemäss der Erfindung die eine Hälfte der Schelle mit zwei Lappen versehen, die federnd in den Steckerkörper eingreifen.
In der Zeichnung ist ein Ausführungsbei spiel für die Zugerrtlastungsvor#richtung eines längsgeteilten Steckers dargestellt. Fig. 1 zeigt einen Schnitt durch eine Steckerhälfte mit dieser Zugentlastungsschelle in Seiten ansicht. Darin bezeichnet 1 den isolierenden Griffkörper des Steckers 3 und 4 die beiden Teile der Zugentlastungsschelle; 5 sind die beiden Schrauben, mit denen die Schelle zu sammengezogen wird, während 2 die Lappen sind, welche federnd in entsprechende Aus sparungen 6 des Steckerkörpers 1 eingreifen und die Schelle vor dem Verlieren schützen. Die Aussparungen, in die die Schrauben 5 hineinragen, sind mit 7 bezeichnet.
Die Schelle kann aus Metall oder Isolierstoff bestehen.
Plug with strain relief. For longitudinally split electrical plugs, the grip body of which consists of two similar insulating halves that are detachably screwed together, strain relief devices for the cable to be inserted are known in the form of two-part clamps, which either lie loosely inside the plug body, or are pressed into it or screwing.
While loosely inserting the clamp has proven to be impractical, as the clamp is easily lost when the connector is opened, i.e. when the handle halves are screwed apart, the other type of fastening, for example by screwing or pressing in, is in the manufacturing process too expensive.
In order to protect the strain relief clamp from being lost even without special fastening elements when the connector is open, one half of the clamp is provided with two tabs that engage resiliently in the connector body.
The drawing shows an exemplary embodiment for the tensioning device of a longitudinally split plug. Fig. 1 shows a section through a connector half with this strain relief in side view. Therein 1 denotes the insulating grip body of the plug 3 and 4 the two parts of the strain relief clamp; 5 are the two screws with which the clamp is pulled together, while 2 are the flaps, which resiliently engage in corresponding recesses from 6 of the plug body 1 and protect the clamp from being lost. The recesses into which the screws 5 protrude are denoted by 7.
The clamp can be made of metal or insulating material.
