Description

Die Erfindung betrifft einen elektrischen Steckverbinder, bestehend aus einem Sockelteil für den Einbau in eine Gehäusewand und einem Verbinderteil mit rückwärtig daran angeordnetem Prüfadapter, das Schraubwinkel zur Verschraubung mit Anlageschultern im Sockelteil aufweist, sowie mit Rastelementen am Sockel- und Verbinderteil, die beim Einsetzen des Verbinderteiles von der der Steckseite abgewandten Innenseite her in das Sockelteil schnappend im Sinne einer Vorfixierung des Verbinderteiles am Sockelteil eingreifen, sowie ferner mit an den Schmalseiten des Verbinderteiles vorgesehenen Schutzkontaktwinkeln.The invention relates to an electrical connector consisting of a base part for installation in a housing wall and a connector part with a test adapter arranged thereon at the rear, which has screw angles for screwing to contact shoulders in the base part, and with latching elements on the base and connector part, which occur when the connector part is inserted from the inside facing away from the plug side, snap into the base part in the sense of pre-fixing the connector part on the base part, and furthermore with protective contact angles provided on the narrow sides of the connector part.

Derartige bekannte elektrische Steckverbinder (DE-A-3 620 719) ermöglichen das zu bevorzugende Einbringen des Verbinderteiles samt Prüfadapter in das auf die Außenseite eines zuvor in die Wand eines Gehäuses, beispielsweise eines Schaltschrankes, montierten Sockelteiles von innen her, und zwar nur durch eine einzelne Person, da es bei diesem Einbringen von innen her aufgrund der Vorfixierung durch die Rastelemente für den Monteur möglich ist, nach Vorfixierung beispielsweise um den Schrank herum zu dessen Außenseite zu gehen, um von dort dann das Verbinderteil und das Sockelteil endgültig fest miteinander zu verschrauben.Known electrical connectors of this type (DE-A-3 620 719) enable the preferred introduction of the connector part together with the test adapter into the base part from the inside, previously mounted on the outside of a wall in a housing, for example a control cabinet, and only by one individual person, since it is possible for the fitter to move from the inside due to the pre-fixation by the locking elements, after pre-fixation, for example, to go around the cabinet to the outside and then finally screw the connector part and the base part firmly together .

Bei dem bekannten elektrischen Steckverbinder sind die Rastelemente einerseits durch auf den beiden Längsinnenwänden des Sockelteiles vorgesehene Keilnoppen sowie andererseits durch auf den Längsseiten des Verbinderteiles angeordnete Rippen gebildet, die beim Einbringen von innen her schnappend über die Keilnoppen gepreßt werden. Infolge dieser Ausgestaltung der Rastelemente für die Vorfixierung ist es praktisch nicht mehr oder nur mit großem Kraftaufwand unter Zerstörungsgefahr möglich, das Verbinderteil in einem Bedarfsfall, beispielsweise bei Irrtum, wieder aus dem Sockelteil herauszunehmen.In the known electrical connector, the latching elements are formed, on the one hand, by wedge knobs provided on the two longitudinal inner walls of the base part and, on the other hand, by ribs arranged on the longitudinal sides of the connector part, which are snap-fitted when inserted from the inside over the wedge knobs. As a result of this configuration of the latching elements for the pre-fixation, it is practically no longer possible or only with great effort and risk of destruction to remove the connector part from the base part if necessary, for example in the event of an error.

Aus der DE-A-1 756 472 ist ferner eine elektrische Steckverbindung bestehend aus einem Kupplungs- und einem Steckerteil bekannt, bei der dem Kupplungsteil Federbeinrasthaken zugeordnet sind, mit denen das Kupplungsteil, wenn es in das Steckerteil eingesteckt ist, zusätzlich an einer Einbauwand durch Verrasten mechanisch gesichert werden kann, wobei das Steckerteil seinerseits an dieser Einbauwand befestigt ist.From DE-A-1 756 472 an electrical plug connection consisting of a coupling and a plug part is also known, in which the coupling part is assigned strut hooks with which the coupling part, when it is plugged into the plug part, additionally through a built-in wall Locking can be secured mechanically, the plug part in turn being attached to this installation wall.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen elektrischen Steckverbinder der gattungsgemäßen Art zu schaffen, bei dem das Verbinderteil mit geringem baulichen Aufwand im Bedarfsfall leicht und ohne Zuhilfenahme von Werkzeugen aus seiner Vorfixierungslage im Sockelteil wieder ausgerastet werden kann.The present invention has for its object to provide an electrical connector of the generic type, in which the connector part can be easily disengaged from its prefixed position in the base part with little construction effort if necessary and without the use of tools.

Die erfindungsgemäße Lösung besteht darin, daß die Rastelemente für die Vorfixierung durch jeweils an den beiden Schmalseiten des Verbinderteiles angeordnete Federbeinrasthaken sowie entsprechend an dem Sockelteil vorgesehene Gegenraststücke gebildet sind und die Federbeinrasthaken einstückig mit Halterungsstegen ausgebildet sind, die auf den Schutzkontaktwinkeln befestigt sind.The solution according to the invention is that the latching elements for the pre-fixation are formed by strut snap hooks arranged on each of the two narrow sides of the connector part and counter-latching pieces correspondingly provided on the base part, and the strut snap hooks are formed in one piece with mounting webs which are fastened to the protective contact angles.

Derartige Federbeinrasthaken bilden ein leicht zu betätigendes elastisches System. Es genügt im Bedarfsfall, von Hand auf die Federbeinrasthaken im Sinne ihrer Entriegelung zu drücken, um die Haken aus dem Gegenraststück freizubekommen. Die Federbeinrasthaken liegen dabei durch ihre Anordnung auf den beiden Schmalseiten des Verbinderteiles auch insgesamt äußerst griffgünstig und können daher auch für die Handhabung des Verbinderteiles mit angeordnetem Prüfadapter insgesamt dienen. Da die vorhandenen seitlichen Schutzkontaktwinkel des Verbinderteiles zur Befestigung der Federbeinrasthaken mit Hilfe der daran einstückig angeordneten Halterungsstege benutzt werden, ist auch ein denkbar einfacher konstruktiver Aufbau erreicht. Zweckmäßig sind dabei ferner an den Halterungsstegen Clipse angeformt, mit denen die Halterungsstege auf die Schutzkontaktwinkel aufgeclipst werden können.Such strut locking hooks form an easy-to-operate elastic system. If necessary, it is sufficient to press the spring strut hooks by hand in the sense of their unlocking in order to free the hooks from the counter-locking piece. Due to their arrangement on the two narrow sides of the connector part, the suspension strut locking hooks are also extremely easy to reach overall and can therefore also serve as a whole for handling the connector part with an arranged test adapter. Since the existing lateral protective contact angles of the connector part are used to fasten the strut locking hooks with the aid of the mounting webs which are arranged thereon in one piece, a very simple construction is also achieved. In this case, clips are also expedient on the mounting webs integrally formed, with which the mounting webs can be clipped onto the protective contact angle.

Der elektrische Steckverbinder hat ein Sockelteil 1, das auf der Außenwand eines Gehäuses, beispielsweise eines Schaltschrankes, im Bereich eines Durchbruches durch die Wand befestigt wird, wozu es mit Schraubflanschen 1a versehen ist. Der elektrische Steckverbinder beinhaltet ferner ein Verbinderteil 2 mit einem daran rückwärtig angeordneten Prüfadapter 2a. Das Verbinderteil 2 mit dem Prüfadapter 2a werden, wie in Figur 1 illustriert, bezogen auf die Gehäusewand von rückwärts, d.h. von der der Steckseite abgewandten Innenseite her, in das Sockelteil eingesetzt und daran befestigt. Für die definitive Befestigung von Verbinderteil 2 und Sockelteil 1 sind dazu an dem Verbinderteil 2 Schraubwinkel 3 vorgesehen, die mittels Schrauben 4 an Anlageschultern 5 im Sockelteil 1 angeschraubt werden können. Um diese Montagegänge von nur einer Person durchführen lassen zu können, ist zwischen dem Sockelteil 1 und dem Verbinderteil 2 eine Rastverbindung für eine Vorfixierung vorgesehen, die es der Person nach dem Einstecken des Verbinderteiles 2 in das Sockelteil 1 von rückwärts bzw. innen ermöglicht, auf die Vorderseite der Gehäusewand, beispielsweise eines Schaltschrankes, zu gehen, um dort die definitive Verschraubung durchzuführen. Um diese Vorfixierung im Bedarfsfall auch leichtgängig und ohne Werkzeug wieder lösen zu können, sind als ein Elementensatz der zusammenwirkenden Rastelemente nun an dem Verbinderteil 2 auf dessen beiden Schmalseiten Federbeinrasthaken 6 vorgesehen, für die in den entsprechenden schmalen Seiten des Innenwandbereiches des Sockelteiles 1 Gegenraststücke 7 vorgesehen sind, die von den Hakenabschnitten am unteren freien Ende der Federbeinrasthaken 6 federnd schnappend im Sinne der Vorfixierung hintergriffen werden.The electrical connector has a base part 1, which is fastened on the outer wall of a housing, for example a control cabinet, in the region of an opening through the wall, for which purpose it is provided with screw flanges 1a. The electrical connector further includes a connector part 2 with a test adapter 2a arranged thereon at the rear. As illustrated in FIG. 1, the connector part 2 with the test adapter 2a is inserted into the base part and fastened to the base part from the rear, ie from the inside facing away from the plug side. For the definitive fastening of connector part 2 and base part 1, screw angles 3 are provided on the connector part 2, which can be screwed onto the shoulders 5 in the base part 1 by means of screws 4. In order to allow these assembly operations to be carried out by just one person, a snap-in connection is provided for a pre-fixation between the base part 1 and the connector part 2, which enables the person after inserting the connector part 2 into the base part 1 from the rear or inside to go to the front of the housing wall, for example of a control cabinet, in order to carry out the final screwing there. In order to be able to release this pre-fixation easily and without tools if necessary, spring strut snap hooks 6 are now provided as a set of elements of the cooperating snap elements on the connector part 2 on its two narrow sides, for which counter locking pieces 7 are provided in the corresponding narrow sides of the inner wall area of the base part 1 are which are snapped behind by the hook sections at the lower free end of the strut locking hook 6 in the sense of pre-fixing.

Die Federbeinrasthaken 6 sind im Bedarfsfall problemlos und griffbequem von Hand zusammenzudrücken, d. h. in Richtung auf das Verbinderteil 2 zu zu bewegen, wodurch die Rastverbindung gelöst wird. Da die Federbeinrasthaken aufgrund ihrer Lage an den beiden Schmalseiten des Verbinderteiles insgesamt besonders griffgünstig liegen, können sie insgesamt auch zur Handhabung des Verbinderteiles als solchem benutzt werden. Sie sind zweckmäßig an ihrer Außenseite mit einer ergonomisch geformten Griffmulde 8 versehen, die im Sinne eines sicheren Greifens in ihrem Grund geriffelt sein kann.The suspension strut hooks 6 can be easily and conveniently pressed together by hand when needed, i.e. H. to move towards the connector part 2, whereby the locking connection is released. Since the strut locking hooks are particularly easy to reach due to their position on the two narrow sides of the connector part, they can also be used as a whole for handling the connector part. They are expediently provided on the outside with an ergonomically shaped recessed grip 8, which can be corrugated in the base in the sense of a secure grip.

In zweckmäßiger, da konstruktiv einfacher Ausgestaltung werden die an den Schmalseiten des Verbinderteiles 2 vorhandenen Schutzkontaktwinkel 9 für die Anbringung und Festlegung der Federbeinrasthaken benutzt. Hierzu sind die Federbeinrasthaken 6 einstückig mit Halterungsstegen 10 geformt, an die ihrerseits abschnittsweise Clipse 11 angeformt sind, die schnappend über einen Abschnitt der Schutzkontaktwinkel 9 geclipst werden können, wie in Figur 3 gezeigt. Ferner ist an den Halterungsstegen 10, nach außen zum Federbeinrasthaken 8 weisend, ein Anschlag 12 angeformt, der dem Schutz des Federbeinrathakens 8 vor zu starken Zusammendrückung dient.In an expedient, structurally simple configuration, the protective contact angles 9 present on the narrow sides of the connector part 2 are used for the attachment and fixing of the strut locking hooks. For this purpose, the strut locking hooks 6 are formed in one piece with mounting webs 10, to which, in turn, sections 11 are integrally formed, which can be snapped onto a section of the protective contact angle 9, as shown in FIG. 3. Furthermore, a stop 12 is formed on the mounting webs 10, pointing outward toward the strut locking hook 8, which serves to protect the strut hook 8 against excessive compression.
