Abstract

The inventive system for preventing a connection screw from screwing itself in is configured in the form of a fork comprising two resilient ribs (4). Said ribs (4) are integrated into the connection bed (3) and are oriented in such a way that they receive the connection screw (2) of a plug-in connection centrally in their opening.

Description

Beschreibungdescription
Eindrehsicherung gegen selbständiges Eindrehen einer AnschlußschraubeProtection against screwing in against the independent screwing in of a connecting screw
Die Erfindung bezieht sich auf eine Eindrehsicherung gegen selbständiges Eindrehen einer Anschlußschraube.The invention relates to a screw-in protection against independent screwing in of a connecting screw.
In der Regel wird dem Kunden ein elektrisches Gerät, z.B. ein Schütz, mit geöffneten Anschlüssen, d.h. mit ausgeschraubten Anschlußschrauben, angeliefert. Durch Erschütterung bzw. Vibrationen während des Transports können sich die Anschlußschrauben selbständig eindrehen. Dieses selbständige Eindrehen soll verhindert werden.As a rule, an electrical device, e.g. a contactor with open connections, i.e. with unscrewed connection screws, delivered. Shock or vibration during transport can cause the connection screws to tighten themselves. This independent screwing in should be prevented.
Bisher sind als Eindrehsicherungen Lösungen bekannt, bei denen durch Reibung das Eindrehmoment erhöht wird. Hierzu werden beispielsweise Rippen vorgesehen, in die sich das Gewinde schneidet oder die am Schraubenkopf reiben. Alternativ werden auch federnde Lappen eingesetzt, die zwischen dem Gewinde und der Aufnahmebohrung für das Gewinde geklemmt werden. Bei anderen Lösungen wird der Schraubenkopf durch Verrastung festgehalten. Eine weitere Möglichkeit besteht darin, die Geräte "über Kopf" zu transportieren, so daß Erschütterungen bzw. Vibrationen ein Ausdrehen der Schrauben bewirken.So far, solutions have been known as anti-screwing devices in which the screwing-in torque is increased by friction. For this purpose, ribs are provided, for example, into which the thread cuts or which rub against the screw head. Alternatively, resilient tabs are used, which are clamped between the thread and the mounting hole for the thread. In other solutions, the screw head is held in place by locking. Another possibility is to transport the devices "overhead" so that shocks or vibrations cause the screws to be unscrewed.
Wird der aus einem Schaltstück mit Anschlußschraube bestehende komplette Anschluß bei der Montage mit eingedrehter Anschlußschraube in ein Anschlußbett eingeschoben, scheiden Lappen aus, die zwischen Gewinde und Aufnahmebohrung für dieIf the complete connection consisting of a contact piece with connecting screw is inserted into a connecting bed during assembly with the screwed-in connecting screw, rags are ruled out, which are between the thread and the mounting hole for the
Anschlußschraube geklemmt werden. Diese sind nur möglich, wenn zuerst das Schalt- bzw. Anschlußstück montiert wird und dann die Anschlußschraube in eine Schraubrichtung zugeführt wird. Rippen, in die sich das Gewinde schneidet, sind ungünstig, da sich das Gewinde bereits beim ersten Ausschrauben in die Rippen schneidet und daher das Eindrehmoment nicht mehr im erforderlichen Maß erhöht wird. Außerdem kann sich eine An- schlußschraube mit Zapfen relativ weit Eindrehen, bevor das Gewinde auf solche Rippen, die erst unterhalb des Gewindedurchzugs beginnen können, trifft.Terminal screw are clamped. These are only possible if the switching or connecting piece is first installed and then the connecting screw is fed in one screwing direction. Ribs into which the thread cuts are unfavorable, since the thread cuts into the ribs the first time they are unscrewed and therefore the tightening torque is no longer increased to the required extent. In addition, a connecting screw with a pin can be screwed in relatively far before the thread hits such ribs, which can only begin below the thread passage.
Am Schraubenkopf reibende Rippen und Verrastungen, die den Schraubenkopf aufnehmen, sind bei relativ tief in der Abdeckkappe eines elektrischen Geräts liegenden Anschlußschrauben nur möglich, wenn ausschließlich mit nichtisolierten Schraubendrehern ein- bzw. ausgeschraubt wird, da die Rippen bzw. Verrastungen die Öffnung für den Schraubendreher zu sehr ver- engen.On the screw head, rubbing ribs and catches, which receive the screw head, are only possible with connection screws located relatively deep in the cover cap of an electrical device if screwing or unscrewing is only done with non-insulated screwdrivers, since the ribs or catches open the opening for the screwdriver too narrow.
Der Erfindung liegt die Aufgabe zugrunde, eine Eindrehsicherung der oben genannten Art zu schaffen, die bei ausgeschraubter Anschlußschraube zuverlässig das selbständige Ein- drehen verhindert, die ein Einschieben des kompletten Anschlusses aus Schaltstück und Anschlußschraube ermöglicht und die beim Ausschrauben die Anschlußschraube nicht beschädigt wird.The invention has for its object to provide an anti-twist device of the type mentioned above, which reliably prevents the screwing in independently when the connecting screw is unscrewed, which enables the complete connection comprising the contact piece and the connecting screw to be inserted and which does not damage the connecting screw when unscrewing.
Die Aufgabe wird dadurch gelöst, daß zwei federnde Rippen in Form einer Gabel vorgesehen sind, die so ausgerichtet ist, daß sie in ihrer Öffnung die Anschlußschraube mittig aufnimmt .The object is achieved in that two resilient ribs are provided in the form of a fork, which is aligned so that it receives the connecting screw centrally in its opening.
Die Gabel ist vorteilhafter Weise derart ausgeführt, daß sie sich bei der Montage eines aus der Anschlußschraube und einem Anschlußstück bestehenden kompletten Anschlusses scherenför- mig öffnet. Weiterhin ist es vorteilhaft, wenn der Abstand der Rippen zueinander kleiner als der Gewindekerndurchmesser bzw. der Zapfendurchmesser einer Anschlußschraube mit Zapfen ist.The fork is advantageously designed in such a way that it opens in a scissor shape when a complete connection consisting of the connecting screw and a connecting piece is installed. It is also advantageous if the spacing of the ribs from one another is smaller than the thread core diameter or the pin diameter of a connecting screw with pin.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained below with reference to a drawing. Show it:
FIG 1 eine perspektivische Ansicht eines in ein Anschlußbett eingeschobenen Anschlusses mit ausgeschraubter Anschlußschraube,1 shows a perspective view of a connector inserted into a connector bed with the connector screw unscrewed,
FIG 2 eine Schnittdarstellung des Anschlusses gemäß FIG 1, FIG 3 eine Unteransicht des Anschlusses gemäß FIG 1 und 2, FIG 4 eine perspektivische Ansicht eines in ein Anschlußbett eingeschobenen Anschlusses mit eingeschraubter Anschlußschraube,2 shows a sectional view of the connection according to FIG. 1, FIG. 3 shows a bottom view of the connection according to FIGS. 1 and 2, FIG. 4 shows a perspective view of a connection inserted into a connection bed with a screwed connection screw,
FIG 5 eine seitliche Schnittansicht des Anschlusses gemäß5 shows a side sectional view of the connection according to
FIG 4 und FIG 6 eine Unteransicht des Anschlusses gemäß FIG 4 und 5.4 and 6 show a bottom view of the connection according to FIGS. 4 and 5.
In Figur 1 ist in einer perspektivischen Schnittdarstellung ein Anschluß aus einem Anschlußstück 1 und einer Anschlußschraube 2 gezeigt, der in ein Anschlußbett 3 eines elektrischen Geräts, z.B. eines Schützes, eingeschoben ist. Unterhalb des eingeschobenen Anschlußstücks 1 ist im Anschlußbett 3 eine Gabel aus zwei federnden Rippen 4 angeformt, die entgegengesetzt der Montagerichtung der Anschlußschraube 2 gemäß Pfeil 5 hervorstehen. Die hier ausgeschraubte, als Kombischraube 2 mit einem Zapfen 6 ausgeführte Anschlußschraube liegt mit dem Zapfen 6 auf den Rippen 4 auf und wird dadurch am selbständigen Eindrehen gehindert. Um dies zu gewährleisten, ist der Abstand der Rippen 4 zueinander kleiner als der Zapfendurchmesser oder der Gewindekerndurchmesser bei einer Anschlußschraube 2 ohne Zapfen 6. Figur 2 zeigt das Anschlußbett 3 mit eingeschobenem Anschluß und ausgeschraubter Kombischraube 2 in einer seitlichen Schnittdarstellung .FIG. 1 shows a perspective sectional view of a connection consisting of a connection piece 1 and a connection screw 2, which is inserted into a connection bed 3 of an electrical device, for example a contactor. Below the inserted connecting piece 1, a fork is formed from two resilient ribs 4 in the connecting bed 3, which protrude in the opposite direction to the mounting direction of the connecting screw 2 according to arrow 5. The screwed here, designed as a combination screw 2 with a pin 6 is located with the pin 6 on the ribs 4 and is thereby prevented from independently turning. In order to ensure this, the spacing of the ribs 4 from one another is smaller than the pin diameter or the thread core diameter in the case of a connecting screw 2 without pin 6. Figure 2 shows the connection bed 3 with inserted connection and unscrewed combination screw 2 in a side sectional view.
In Figur 3 ist eine zugehörige Unteransicht dargestellt.An associated bottom view is shown in FIG.
Figur 4 , 5 und 6 zeigen den in das Anschlußbett 3 eingeschobenen Anschluß mit eingeschraubter Kombischraube 2 in verschiedenen Darstellungen. Beim Einschub des kompletten An- Schluß öffnet sich die Gabel mit den beiden federnden Rippen 4 scherenförmig, so daß die Rippen 4 nicht beschädigt werden. Hierzu ist die Gabel so ausgerichtet, daß sie in ihrer Öffnung die Anschlußschraube 2 mittig aufnimmt. Besonders vorteilhaft ist es, wenn die beiden Rippen 4 mehr als den halben Schraubendurchmesser überdecken.Figures 4, 5 and 6 show the connection inserted in the connection bed 3 with the screwed-in combination screw 2 in different representations. When the complete connection is inserted, the fork with the two resilient ribs 4 opens in a scissor-like manner so that the ribs 4 are not damaged. For this purpose, the fork is aligned so that it receives the connecting screw 2 in the center of its opening. It is particularly advantageous if the two ribs 4 cover more than half the screw diameter.
Beim Ausschrauben schneidet sich das Gewinde der Anschlußschraube 2 kaum in die Rippen 4, da die Kräfte durch Verbie- gung der Rippen 4 relativ gering sind. Nach dem Ausschrauben der Anschlußschraube 2 geht die Gabel fast vollständig wieder in ihre Ausgangsstellung zurück. Die Gabel hält die Anschlußschraube 2 bereits bei Berührung durch den Zapfen 6 bei ausgeschraubter Anschlußschraube 2, so daß diese nicht erst um die Zapfenlänge aus dem Gewinde herausschauen muß. When unscrewing, the thread of the connecting screw 2 hardly cuts into the ribs 4, since the forces due to bending of the ribs 4 are relatively low. After unscrewing the connecting screw 2, the fork almost completely returns to its starting position. The fork holds the connecting screw 2 when it is touched by the pin 6 when the connecting screw 2 is unscrewed, so that it does not have to look out of the thread by the pin length.
