Staubschutzverschlußplättchen an KabelverschraubungenDust protection plate on cable glands

Die Anmeldung bezieht sich auf den lösbaren Verschluß der Kabeleinführtmgaöf fnung an vormontierten Kabelverschraubungen. Der Staubschutzverschluß verhindert das Eindringen von Wasser, Staub und Fremdkörpern in Maschinen und Geräte vor der Kabelmontage.The application relates to the releasable closure of the cable entry mechanism Opening on pre-assembled cable glands. The dust cover prevents the ingress of water and dust and foreign bodies in machines and devices prior to cable assembly.

Die bekannte Art der Verschließung von Kabeleinführungsöffnungen erfolgte bisher mit Verschlußschrauben gemäß DIN 46 320, allgemein als Blindstopfen bezeichnet. Diese Verschlußschrauben müssen zur Montage der Kabelverschraubung^ demontiert werden. Dadurch entstehen zusätzliche Montage- und Materialkosten.The known way of closing cable entry openings was previously carried out with screw plugs in accordance with DIN 46 320, generally referred to as blind plugs. These screw plugs must to assemble the cable gland ^ must be dismantled. Through this there are additional assembly and material costs.

Der Erfindung liegt die Aufgabe zugrunde, die Montagefreundlichkeit zu erhöhen und gleichzeitig die Kosten zu senken. Dies läßt sich erfindungsgemäß dadurch erreichen, daß die Verschlußschraube entfällt und an ihrer Stelle die Kabelverschraubung derart vorzumontieren ist, daß die Kabeleinführungsöffnung zwischen Druckschraube und Zwischenstutzen durch das Staubschutzverschlußplättchen verschlossen wird. Bei der Kabelmontage drückt das einzuführende Kabel das Verschlußplättchen aus der festen Halterung, d.h. in einem Arbeitsgang werden das Kabel eingeführt und der Verschluß gelöst. Das Verschlußplättchen liegt in den Herstellungskosten so niedrig, daß es bei der Montagekostenkalkulation fast unberücksichtigt bleiben kann.The invention is based on the problem of ease of assembly increase while reducing costs. This can be achieved according to the invention in that the locking screw omitted and in its place the cable gland is to be pre-assembled in such a way that the cable entry opening between the pressure screw and the intermediate stub is closed by the dust protection closure plate. When installing the cable, this is pressing Cable to be inserted remove the locking plate from the fixed holder, i.e. the cable is inserted in one operation and the lock released. The closure plate is so low in the manufacturing costs that it is in the assembly cost calculation can almost be disregarded.

Kennzeichen der Erfindung sind, daß das dünne Staubschutzverschlußplättchen aus einem weichelastischen Werkstoff hergestellt ist. Festigkeit, Dehnung und Rauhigkeit der Oberfläche des Werkstoffes sind so eingestellt, daß das Plättchen durch das einzuführende Kabel nicht durchstoßen, sondern aus der Einspannung verdrängt wird. Diese Materialeigenschaften werden beispielsweise von besonderen weichelastischen Polyurerthanrschäumen erfüllt.Characteristics of the invention are that the thin dust protection closure plate is made of a soft elastic material. Strength, elongation and roughness of the surface of the material are set so that the plate does not pierce through the cable to be inserted, but from the Restraint is displaced. These material properties are for example from special flexible polyurethane foams Fulfills.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung
dargestellt. Darin zeigen:In the drawing is an embodiment of the invention
shown. Show in it:

Fig. 1 eine Vorderansicht und die Draufsicht des Staubschutzverschlußplättchens Fig. 1 is a front view and a plan view of the dustproof shutter plate

Fig. 2 eine Kabelverschraubung im Halbschnitt mit zwischen
Druckschraube und Zwischenstutzen eingespanntem
Staubschutzverschlußplättchen.Fig. 2 is a cable gland in half section with between
Pressure screw and intermediate socket clamped
Dust protection cover plate.

Das in dem Ausführungsbeispiel dargestellte Staubschutzverschlußplättchen (1) nach Fig. 1 besteht aus weichelastischem Kunststoff. Fig. 2 zeigt eine Kabelverschraubung (2), welche an einem Gehäuseteil (3) befestigt ist. Zwischen dea Verschraubungsteilen Druckschraube (k) und Zwischenstutzen (5) ist das Staubschußverschlußplättchen (i) unverlierbar eingespannt und verschließt damit die
Kabeleinführungsöffnung (6). Bei Kabeleinführung in den Pfeilrichtungen (7) wird das Staubschutzverschlußplättchen aus dem
ringförmigen Einspannbund (8) gedrückt, ohne daß eine Lockerung
der Verbindung zwischen Druckschraube (k) und Zwischenstutzen (5) eintritt.The dust protection closure plate (1) shown in the embodiment according to FIG. 1 consists of flexible plastic. Fig. 2 shows a cable gland (2) which is attached to a housing part (3). Between union parts dea pressure screw (k) and the intermediate piece (5) the excess dust closure plate (i) is clamped captively and closes so that the
Cable entry opening (6). When the cable is inserted in the directions of the arrows (7), the dust protection cap is removed from the
annular clamping collar (8) pressed without loosening
the connection between the pressure screw (k) and the intermediate socket (5) occurs.

Claims (3)
