Description

Die zum Gebrauchsmuster anzumeldende einteilige, eindrückbare und durch Verschraubung festsetzbare Kabelzugentlastung dient dazu, das durch das Gehäuseteil zum Aggregat führende Kabel am Gehäuse oder an innen liegenden Bauteilen gegen Herausziehen und Hineinschieben zu sichern.The one-piece, push-in cable strain relief to be registered for the utility model, which can be fixed by screwing, serves to secure the cable leading through the housing part to the unit on the housing or on internal components against being pulled out and pushed in.

Es gibt bereits für diesen Anwendungszweck eine Reihe von Elementen, die jedoch zumeist mehrteilig sind und durch Schraubelemente gesondert befestigt werden müssen. Der Vorzug des von uns entwickelten Teiles liegt in seiner einfachen Montagemöglichkeit, seiner Universalität bezüglich der Kabeldurchmesser und der Tatsache, dass nur ein einziges Element montiert zu werden braucht.There are already a number of elements for this purpose, but most of them are made up of several parts and have to be fastened separately using screw elements. The advantage of the part developed by us lies in its simple installation option, its universality with regard to the cable diameter and the fact that only a single element needs to be installed.

Claims

Our protection claims are broken down as follows:

a) One-piece, push-in cable strain relief that can be fixed by screwing, which is characterized in that the ring-shaped, internally threaded upper part (Fig. 3) is connected to the externally threaded cable clamping part (Fig. 2) and by tightening the thread by means of the upper part in the spreading frame (Fig. 1) sitting in between is pulled in, causing the cable to be clamped and the entire part (Fig. 4) to be fixed by spreading the spreading frame (Fig. 1).

b) Also characterized in that a longitudinal web is placed on the spreading foot (4 pieces in total) in the expansion frame (Fig. 1), which prevents twisting of the cable clamping part (Fig. 2) when the thread is tightened.

c) Characterized in that the ring-shaped upper part (Fig. 3) is provided on its outer diameter with evenly distributed knobs or surfaces, which are used to attach the wrench and shear off at a certain tightening torque and thus prevent over-turning of the inner thread.

d) Characterized in that there is a knob on the outer part of the splayfoot which engages in a corresponding recess of the sheet metal bore provided for the partial receptacle and prevents the entire part from rotating.

e) This is indicated by the fact that all three parts (Fig. 4) form a unit upon delivery. f) Characterized in that this cable strain relief as a unit can consist of both thermoplastic and thermosetting plastics in its individual components or individual parts of this overall part can consist of different materials of the two product groups.
