Description

Die Erfindung betrifft eine Geräte-Steckdose mit einem aus Isolierwerkstoff bestehenden Steckdosen-Sockel, der hinter zwei benachbarten Steckeröffnungen die stromführenden Strom- Kontakte und hinter einer weiteren Steckeröffnung einen Erdungskontakt trägt, sowie mit einem quer zur Steckrichtung gegen eine Rückstellkraft, wie eine Rückstellfeder, aus der Abdeckstellung in eine Freigabestellung bewegbar gelagerten Kontakt-Abdeckglied zum einsteckseitigen Abdecken der stromführenden Kontakte bei herausgezogenen Steckerstiften des zugehörigen Steckers.The invention relates to a device socket with a socket made of insulating material, which carries the current-carrying current contacts behind two adjacent plug openings and a ground contact behind a further plug opening, and with a transverse to the plug-in direction against a restoring force, such as a return spring the cover position in a release position movably mounted contact cover member for covering the plug-in side of the current-carrying contacts when the plug pins of the associated plug are pulled out.

Durch die US-A-3 865 456 ist eine Geräte-Steckdose bekanntgeworden, bei welcher das Abdeckglied an einer vom Steckdosen-Sockel gesonderten, blendenartigen Deckplatte vorgesehen und so ausgebildet ist, daß es, nach Einsetzen der kurzen, verjüngten Endabschnitte der Steckerstifte in die Öffnungen, durch eine Querbewegung des Steckers entgegen der Kraft der Rückstellfeder in die Freigabestellung verschoben werden muß, in welcher die Öffnungen mit den Steckeröffnungen des, als Steckdosen-Grundkörper vorgesehenen Sockels fluchten. Wann diese fluchtende Lage erreicht wird, kann nur durch Ertasten festgestellt werden, und hierzu muß während des genannten Verschiebens der Abdeckplatte mit Hilfe des Steckers ständig eine gegen den Sockel gerichtete Druckbelastung ausgeübt werden, um nämlich anhand des Nachgebens des Steckers in Steckrichtung festzustellen, daß nunmehr die Öffnungen mit den Steckeröffnungen in eine Deckungslage gelangt sind. Die Steckerstifte müssen also zunächst in eine mit den Steckeröffnungen nicht fluchtende Vorsteckstellung gebracht und dann unter Druckbelastung entlang der Frontfläche des Stecker-Sockels bis zu den Steckeröffnungen querbewegt werden, was zwangsläufig zu einer ganzen Reihe von nachteiligen Wirkungen führt.From US-A-3 865 456 a device socket has become known, in which the cover member is provided on a separate from the socket base, aperture-like cover plate and is designed so that it, after inserting the short, tapered end portions of the connector pins in the Openings must be moved by a transverse movement of the plug against the force of the return spring in the release position in which the openings are aligned with the plug openings of the base provided as a socket body. When this aligned position is reached can only be determined by palpation, and for this purpose a pressure load directed against the base must be constantly exerted during the said displacement of the cover plate with the aid of the plug, in order to determine that now that the plug is yielding the openings with the plug openings have reached a cover position. The connector pins must therefore first be brought into a pre-aligned position that is not aligned with the connector openings and then moved under pressure along the front surface of the connector base up to the connector openings, which inevitably leads to a whole series of disadvantageous effects.

Die Leichtgängigkeit der Abdeckplatte in den zu ihrer Lagerung vorgesehenen, V-förmigen Gleitnuten der Deckplatte neigt mit Sicherheit dazu, aus vielerlei Gründen beeinträchtigt zu sein. Bereits die bei Steckdosen häufig zu beobachtenden Verschmutzungen können schnell zum schwergängigen Festsetzen des Abdeckgliedes in den Gleitnuten führen. Auch das nicht sorgsame Ansetzen des Steckers an der Deckplatte kann zu Beschädigungen der Gleitführung für das Abdeckglied führen, da mit den Enden der Steckerstifte im Bereich der seitlichen Randzonen einer Fensteröffnung der Deckplatte auf die Teile der Gleitführung, nämlich sowohl auf die Deckplatte, als auch auf das Abdeckglied selbst, relativ hohe spezifische Flächendrücke ausgeübt werden können, die zu Verformungen und damit zu einer so starken Beeinträchtigung der Leichtgängigkeit des Abdeckgliedes führen, daß dieses sogar vollständig festsitzt oder nur mit äußerst hohen Querkräften noch zu verschieben ist.The smooth running of the cover plate in the V-shaped sliding grooves of the cover plate provided for its storage certainly tends to be impaired for many reasons. Even the soiling that can often be observed in sockets can quickly lead to the cover member becoming stuck in the slide grooves. Even the careless placement of the connector on the cover plate can damage the slide guide for the cover member, since with the ends of the connector pins in the area of the lateral edge zones of a window opening of the cover plate on the parts of the slide guide, namely both on the cover plate and on the cover member itself, relatively high specific surface pressures can be exerted, which lead to deformations and thus to such a great impairment of the smoothness of the cover member that it is even completely stuck or can only be shifted with extremely high transverse forces.

Des weiteren kann die Leichtgängigkeit des Abdeckgliedes dadurch wesentlich beeinträchtigt werden, daß es bei nicht gleichmäßiger Verschiebebelastung über beide Steckerstifte verkantet und dabei mit zwei durch es gebildeten Eckbereichen verformend und somit beschädigend in die Gleitnut eindringt, wodurch danach ein bestimmungsgemäßes Verschieben des Abdeckgliedes kaum mehr möglich erscheint. Des weiteren wird bei der bekannten Ausbildung die Deckplatte mit einer zentralen Schraube gegen den gehäuseförmigen Sockel gespannt und dadurch als Ganzes einer sie krümmenden Verformung ausgesetzt, in welche die Gleitführungen für das Abdeckglied so einbezogen sind, daß die Reibung zwischen dem Abdeckglied und der Blendenplatte bis zum völligen Festsitzen des Abdeckgliedes erhöht wird.Furthermore, the smoothness of the cover member can be significantly affected by the fact that it canting over both connector pins when the displacement load is not uniform and deforms with two corner regions formed by it and thus penetrates into the sliding groove, so that a proper displacement of the cover member then hardly seems possible . Furthermore, the cover plate is tensioned with a central screw against the housing-shaped base and thereby exposed as a whole to a curvature deformation in which the sliding guides for the cover member are included so that the friction between the cover member and the diaphragm plate up to complete tightness of the cover member is increased.

Unabhängig davon, welcher der zahlreichen möglichen Faktoren zur Schwergängigkeit bzw. zum Festsetzen des Abdeckgliedes führt, ergibt sich, daß die ohnehin nur mit äußerst kurzen, nämlich der Dicke des Abdeckgliedes entsprechenden Endabschnitten in die Öffnungen eingreifenden Steckerstifte während der Querbewegung des Abdeckgliedes leicht und daher des öfteren aus diesen Öffnungen abrutschen können, was zu einem schnellen Beschädigen bzw. Abschaben der zugehörigen Begrenzungen der Öffnungen führt, so daß bereits nach kürzester Zeit ein formschlüssiger Eingriff der Steckerstifte in die Öffnungen zum Zwecke des Verschiebens des Abdeckgliedes nicht mehr möglich ist. Gleichzeitig schaben die Endflächen der Steckerstifte wegen des für die bestimmungsgemäße Verwendung erforderlichen Anpreßdruckes an der Vorderfläche des Steckdosen-Sockels, bis sie die Steckeröffnungen erreicht haben, was sowohl zu einer kratzenden Beschädigung der Vorderfläche des Steckdosen-Sockels führt als auch die vorderen Enden der Steckerstifte mit der Zeit beschädigen kann.Regardless of which of the numerous possible factors leads to stiffness or fixing of the cover member, it follows that the plug pins engaging in the openings anyway with extremely short end sections, which correspond to the thickness of the cover member, are light and therefore of the same during the transverse movement of the cover member can often slip out of these openings, which leads to rapid damage or scraping of the associated boundaries of the openings, so that after a very short time a positive engagement of the connector pins in the openings for the purpose of moving the cover member is no longer possible. At the same time, the end surfaces of the plug pins scrape on the front surface of the socket base because of the contact pressure required for the intended use until they have reached the plug openings, which both leads to scratching damage to the front surface of the socket base and also to the front ends of the plug pins that can damage time.

Darüberhinaus sind die über den Stecker, insbesondere bei Schwergängigkeit des Abdeckgliedes, auf das Abdeckglied zu übertragenden Querkräfte geeignet, die Verankerung der Steckerstifte in dem Stecker zumindest allmählich zu lockern, was zu wesentlichen Beeinträchtigungen der elektrischen Sicherheit führen kann. Schließlich ist es auch so, daß, wenn die Steckerstifte beim Querverschieben des Abdeckgliedes in die Bereiche der Steckeröffnungen gelangen, diese Steckerstifte aufgrund ihrer bestimmungsgemäßen Anpreßbelastung schlagartig über die zugehörigen Randbegrenzungen der Steckeröffnungen gleiten und hierbei ein Ausbrechen dieser Randbegrenzungen hervorrufen können, zumal Steckdosen-Sockel in der Regel aus einem relativ spröden Isolationswerkstoff bestehen.In addition, the transverse forces to be transmitted to the cover member via the plug, particularly if the cover member is difficult to loosen, are at least gradually loosening the anchoring of the plug pins in the plug, which can lead to significant impairments in electrical safety. Finally, it is also the case that when the connector pins get into the areas of the connector openings when the cover member is moved laterally, these connector pins suddenly slide over the associated edge limits of the connector openings due to their intended contact pressure and can cause these edge limits to break out, especially since the socket base in usually consist of a relatively brittle insulation material.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Geräte-Steckdose zu schaffen, die ein einfaches und schonendes Einführen des zugehörigen Steckers gewährleistet.In contrast, the invention has for its object to provide a device socket that easy and gentle insertion of associated connector guaranteed.

Zur Lösung dieser Aufgabe ist bei einer Geräte-Steckdose der eingangs beschriebenen Art erfindungsgemäß vorgesehen, daß das Abdeckglied zur Überführung in die Freigabestellung mit wenigstens einer in Abdeckstellung im Bereich der zugehörigen Steckeröffnung liegenden schrägen Auflauffläche für mindestens einen Steckerstift versehen und an dem die Kontakte tragenden Sockel gelagert ist.To solve this problem it is provided according to the invention in a device socket of the type described at the outset that the cover member for transfer to the release position is provided with at least one oblique ramp surface in the cover position in the area of the associated plug opening for at least one plug pin and on the base carrying the contacts is stored.

Dadurch kann der Stecker bereits beim Ansetzen an die Steckdose in seiner bestimmungsgemäß gegenüber den Steckeröffnungen ausgerichteten Lage gehalten werden, wonach er lediglich durch Belastung in Längsrichtung seiner Steckerstifte in seine Einstecklage findet. Da das Abdeckglied unmittelbar am Steckdosen-Sockel verschiebbar gelagert ist, der im Gegensatz zu Steckdosen-Deckplatten eine hohe Formstabilität aufweist, ergibt sich auch bei kompakter Ausbildung eine wesentlich präzisere Lagerung, so daß die Leichtgängigkeit des Abdeckgliedes kaum beeinträchtigt werden kann, zumal die Gleitlagerung nicht durch das Festziehen einer Befestigungsschraube unter Spannung gesetzt werden kann.As a result, the plug can already be held in its intended position in relation to the plug openings when it is attached to the socket, after which it only finds its insertion position by loading in the longitudinal direction of its plug pins. Since the cover member is slidably mounted directly on the socket base, which, in contrast to socket cover plates, has a high dimensional stability, there is a much more precise storage even with a compact design, so that the smoothness of the cover member can hardly be impaired, especially since the plain bearing does not can be put under tension by tightening a fastening screw.

Nach einer Weiterbildung der Erfindung ist die Auflauffläche einem voreilenden Steckerstift zugeordnet und liegt sie insbesondere in Abdeckstellung vor dem Erdungskontakt. Dabei können vorzugsweise die Steckeröffnungen am Boden einer Versenkung für die Aufnahme eines Isolierträgers des Steckers derart vorgesehen sein, daß die Versenkung vor Erreichen der stromführenden Kontakte durch die zugehörigen Steckerstifte von dem Isolierträger nach außen geschlossen ist. Die Anordnung ist dabei zweckmäßig so getroffen, daß die Versenkung durch den lsolierträger nach außen bereits bei Erreichen des Erdungskontaktes durch den zugehörigen Steckerstift geschlossen ist, so daß eine besonders hohe elektrische Sicherheit erreicht wird.According to a further development of the invention, the run-up surface is assigned to a leading plug pin and lies in particular in the cover position in front of the ground contact. In this case, the plug openings can preferably be provided on the bottom of a countersink for receiving an insulating carrier of the plug such that the countersink is closed to the outside by the insulating carrier before the current-carrying contacts are reached by the associated plug pins. The arrangement is expediently such that the recess is closed to the outside by the insulating support when the ground contact is reached by the associated plug pin, so that particularly high electrical safety is achieved.

Eine besonders raumsparende und störungsunanfällige Bauweise, bei welcher die Steckdose gleiche äußere Abmessungen bzw. Form behalten kann, ergibt sich, wenn das quer zur Steckrichtung bewegbar gelagerte Abdeckglied zwischen einer die Steckeröffnungen aufweisenden Wandung des Sockels und den Kontakten im wesentlichen verdeckt angeordnet und vorzugsweise zwischen einem die Kontakte tragenden und einem die Versenkung bildenden Sockelteil angeordnet, insbesondere in einer, Gleitflächen bildenden Vertiefung in der Rückseite des vorderen Sockelteiles anschlagbegrenzt verschiebbar gelagert ist. Dadurch ist das Abdeckglied einschließlich seiner Lagerung sehr gut vor Verschmutzungen geschützt und sogar bei ggf. bereits teilweise beschädigtem Steckdosen-Sockel noch voll wirksam. Des weiteren ergibt sich bei einfacher Herstellbarkeit eine einfache Gleitlagerung ohne zusätzliche Lagerteile. Auch ist durch die beschriebene Ausbildung auf einfache Weise eine durchgehend einstückige Ausbildung des Abdeckgliedes und damit eine weitere wesentliche Verringerung der Störungsanfälligkeit möglich.A particularly space-saving and failure-prone design, in which the socket can retain the same external dimensions or shape, is obtained if the cover member, which is mounted transversely to the plugging direction, is arranged essentially concealed between a wall of the base having the plug openings and the contacts, and preferably between one the contacts carrying and a recess forming the base part is arranged, in particular in a, forming sliding surfaces recess in the back of the front base part is slidably mounted. As a result, the cover member, including its storage, is very well protected against dirt and is still fully effective even if the socket base is already partially damaged. Furthermore, a simple slide bearing without additional bearing parts results with simple manufacturability. The design described also makes it possible in a simple manner to provide a continuous, one-piece design of the cover member and thus a further substantial reduction in susceptibility to failure.

Nach einer weiteren Ausbildung der Erfindung ist die Auflauffläche an einem verdickten Abschnitt des Abdeckgliedes vorgesehen, der vorzugsweise durch einen Steg an der Vorderseite des Abdeckgliedes gebildet sowie in einem die zugehörige Steckeröffnung einschließenden Schlitz des Sockels geführt ist. Dadurch kann trotz relativ dünner und damit gewichts- sowie raumsparender Ausbildung des Abdeckgliedes zur Erzielung günstiger Kräfteverhältnisse eine verhältnismäßig flach geneigte Auflauffläche vorgesehen werden. Durch den verdickten Abschnitt ist das Abdeckglied zusätzlich gegenüber dem Steckdosen-Sockel geführt, und es ist jederzeit optisch leicht erkennbar, daß das Abdeckglied in Abdeckstellung steht. Das plattenförmige Abdeckglied läßt sich auch bei schwacher Dimensionierung und geringem Gewicht mit hoher Stabilität, insbesondere mit hoher Bruchfestigkeit und hoher Stoßfestigkeit ausstatten. Ferner läßt sich das so ausgebildete Abdeckglied, insbesondere bei rechteckiger Plattenform, auf einfache Weise mit zwei seitlichen Kantenflächen einfach lagern und gegen seitliches Verschieben sichern, ohne daß hierfür gesonderte weitere Lagermittel erforderlich sind. Vorteilhaft ist das Abdeckglied parallel zur Plattenebene bzw. zu den kürzeren Plattenkanten verschiebbar gelagert ; auch kann es stattdessen oder zusätzlich hierzu rechtwinklig zur gemeinsamen Axialebene der Stromkontakte verschiebbar gelagert sein ; auch der Erdungskontakt kann in dieser Axialebene, nämlich zwischen den Stromkontakten, liegen.According to a further embodiment of the invention, the run-up surface is provided on a thickened section of the cover member, which is preferably formed by a web on the front side of the cover member and is guided in a slot in the base including the associated plug opening. In this way, despite the relatively thin and thus weight-saving and space-saving design of the cover member, a relatively flat inclined contact surface can be provided to achieve favorable force relationships. Through the thickened section, the cover member is additionally guided relative to the socket base, and it is easy to see at any time that the cover member is in the cover position. The plate-shaped cover member can be equipped with high stability, in particular with high breaking strength and high impact resistance, even with weak dimensions and low weight. Furthermore, the cover member formed in this way, in particular in the case of a rectangular plate shape, can be easily stored with two lateral edge surfaces and secured against lateral displacement without the need for separate additional storage means. The cover member is advantageously mounted to be displaceable parallel to the plane of the plate or to the shorter plate edges; instead, or in addition thereto, it can also be displaceably mounted at right angles to the common axial plane of the current contacts; the grounding contact can also lie in this axial plane, namely between the current contacts.

Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Ausbildung liegt darin, daß das Abdeckglied praktisch nur mit dem passenden Stecker in die Freigabestellung überführt werden kann. Dies ist insbesondere der Fall, wenn die Auflauffläche des Abdeckgliedes im Querschnitt wenigstens annähernd an den zugehörigen Steckerstift angepaßt, insbesondere rinnenförmig ausgebildet und vorzugsweise am zugehörigen Ende des -Steges des Abdeckgliedes vorgesehen ist, wodurch auch eine verbesserte Führung sowie eine Verringerung der spezifischen Flächenpressung erreicht werden kann.Another significant advantage of the design according to the invention is that the cover member can practically only be moved into the release position with the appropriate plug. This is particularly the case if the contact surface of the cover member is at least approximately matched in cross-section to the associated plug pin, in particular is formed in a channel shape and is preferably provided at the associated end of the web of the cover member, which also leads to improved guidance and a reduction in the specific surface pressure can.

Das Abdeckglied kann auch bei verhältnismäßig klein dimensionierter Steckdose verhältnismäßig und vor allem hinreichend massiv ausgebildet werden, wenn es in der Freigabestellung aus dem Sockel mit einer Randzone vorsteht, wodurch auch eine sehr einfache Montage des Abdeckgliedes durch Einschieben von der Außenseite des Steckdosen-Sockels her möglich ist. Ferner kann dadurch die wegen ihrer Wärmefestigkeit bevorzugt metallische Rückstellfeder an die Außenseite des Sockels verlegt werden, so daß auch bei einem eventuellen Federbruch keine Gefahr besteht, daß Teile der Feder in leitenden Kontakt mit stromführenden Teilen der Steckdose gelangen können. Bei einer einfachen Ausbildung ist die vorgespannte Rückstellfeder, wie eine Blattfeder, im Bereich der genannten Randzone, insbesondere an der demgegenüber wenigstens teilweise vorstehenden Endfläche des Steges, abgestützt.The cover member can be formed relatively and above all sufficiently solid even with a relatively small-sized socket if it protrudes from the base with an edge zone in the release position, which also makes very simple assembly of the cover member possible by pushing in from the outside of the socket base is. Furthermore, because of its heat resistance, the preferably metallic return spring can be moved to the outside of the base, so that even if the spring breaks, there is no danger that parts of the spring can come into conductive contact with live parts of the socket. In the case of a simple design, the prestressed return spring, such as a leaf spring, is supported in the region of the edge zone mentioned, in particular on the end face of the web which at least partially protrudes.

Zur einfachen und sicheren Lagerung ist die vorzugsweise bogenförmig gekrümmte Rückstellfeder mit beiden Enden in Schlitzen des Sockels gelagert und etwa in der Mitte zwischen ihren Enden am Abdeckglied abgestützt sowie insbesondere mit einer aufgerichteten, das Abdeckglied hintergreifenden Lasche gesichert, wodurch auch eine einfachere Montage der Rückstellfeder gewährleistet ist. Zweckmäßig befindet sich die Rückstellfeder bei montierter Steckdose an der Unterseite von deren Sockel, so daß bei einem eventuellen Federbruch die Bruchteile der Rückstellfeder sich vom Sockel lösend nach unten fallen und nicht in die Steckdose ein- oder zu deren Anschlußklemmen vordringen können.For simple and safe storage, the preferably arc-shaped return spring is supported with both ends in slots in the base and is supported approximately in the middle between its ends on the cover member and in particular secured with an upright tab that engages behind the cover member, which also ensures easier assembly of the return spring is. The return spring is expediently located on the underside of its base when the socket is mounted, so that in the event of a spring breakage, the fractions of the return spring come loose from the base and cannot penetrate into the socket or penetrate into its connecting terminals.

Das Abdeckglied kann in seiner Abdeckstellung vor allem dann genau festgelegt sein, wenn es in dieser Stellung anschlagbegrenzt ist, wobei vorzugsweise die zugehörige Außenkante des Abdeckgliedes an der gegenüberliegenden Begrenzungsfläche der die Gleitflächen bildenden Vertiefung des Sockels anliegt, so daß keine gesonderten Anschlagglieder erforderlich sind und die Auflauffläche in der Abdecklage gegenüber der zugehörigen Steckeröffnung stets dieselbe Lage einnimmt.The cover member can be precisely fixed in its cover position especially when it is stop-limited in this position, the associated outer edge of the cover member preferably abutting the opposite boundary surface of the depression of the base forming the sliding surfaces, so that no separate stop members are required and Run-up surface in the cover position opposite the associated plug opening always occupies the same position.

In weiterer Ausgestaltung der Erfindung besteht das, insbesondere durchgehend einstückig ausgebildete Abdeckglied wenigstens im Bereich der Kontakte im wesentlichen aus dem gleichen Isolierwerkstoff wie der Sockel, vorzugsweise aus Keramikwerkstoff, wobei es insbesondere mindestens an der Auflauffläche durch eine Lasurschicht oder dgl. als reibungsarme Gleitfläche ausgebildet ist, so daß zum Überführen in die Freigabestellung nur geringe Kräfte aufgebracht werden müssen. Besonders zweckmäßig ist es, das Abdeckglied als durchgehend einstückigen, monolithischen Teil auszubilden, so daß für die erfindungsgemäße Ausbildung noch weniger Teile benötigt werden als für eine gleichartige Steckdose mit Blindstecker.In a further embodiment of the invention, the cover member, which is formed in particular in one piece, at least in the area of the contacts, consists essentially of the same insulating material as the base, preferably of ceramic material, wherein it is in particular formed at least on the contact surface by a glaze layer or the like as a low-friction sliding surface , so that only small forces have to be applied to transfer to the release position. It is particularly expedient to design the cover member as a one-piece, monolithic part, so that even fewer parts are required for the inventive design than for a similar socket with a dummy plug.

Es hat sich überraschend gezeigt, daß es durch die erfindungsgemäße Ausbildung möglich ist, das Abdeckglied-mit relativ hoher Genauigkeit aus dem ansonsten verhältnismäßig schwer formbaren Steatit herzustellen.It has surprisingly been found that the design according to the invention makes it possible to manufacture the cover member with relatively high accuracy from the otherwise relatively difficult to form steatite.

Durch die erfindungsgemäße Ausbildung wird ferner der wesentliche Vorteil erreicht, daß das Abdeckglied in der Abdecklage nicht nur die stromführenden Kontakte, sondern auch den Erdungskontakt abdeckt, so daß auch letzterer vor den beschriebenen schädlichen Einflüssen geschützt ist. Eventuell durch die Steckeröffnung bis zum Abdeckglied vordringende Reinigungs-oder Schmutzsubstanzen können dadurch, daß das Abdeckglied aus dem Sockel herausgeführt ist, selbsttätig wieder aus dem Sockel gelangen, so daß ein allmähliches Zusetzen der Gleitflächen für das Abdeckglied nicht zu befürchten ist.The design according to the invention also achieves the essential advantage that the cover member not only covers the current-carrying contacts but also the grounding contact in the cover position, so that the latter is also protected from the harmful influences described. Possibly cleaning or dirt substances penetrating through the plug opening to the cover member can automatically come out of the base again by the cover member being led out of the base, so that a gradual clogging of the sliding surfaces for the cover member is not to be feared.

Durch die beschriebenen Vorteile eignet sich die erfindungsgemäße Steckdose insbesondere für den Innenraum eines Backofens, wo sie außer als elektrischer Anschluß auch unmittelbar als Halterung für einen Grillheizkörper oder dgl. eingesetzt werden kann.Due to the advantages described, the socket according to the invention is particularly suitable for the interior of an oven, where it can also be used directly as a holder for a grill heater or the like in addition to an electrical connection.

Wie die Figuren 1 bis 7 zeigen, besteht eine erfindungsgemäße, als Grill-Steckdose ausgebildete Geräte-Steckdose, die für den Anschluß von unterschiedlichen Grillheizkörpern oder anderen, im Haushalt bzw, im Backofen zu verwendenden Geräten, wie Grill-Motoren, Umluft-Gebläsen oder dgl., vorgesehen sein kann, im wesentlichen aus einem zweiteiligen Sockel 1 aus Isolierwerkstoff, der als Gehäuse ausgebildet ist. Zwischen den beiden Sockelteilen 2, 3 des Sockels 1 ist ein Abdeckglied 4 verschiebbar gelagert. In dem Sockel 1 sind stromführende Kontakte 5 sowie ein Erdungskontakt 6 vorgesehen, und die beiden Sockelteile 2, 3 sind durch zwei hohle Nieten 8 zusammengehalten. Das Abdeckglied ist durch eine Rückstellfeder 7 zu seiner Abdecklage hin federbelastet. Ausgenommen die stromführenden Kontakte 5 mit den nicht näher dargestellten Anschlußgliedern bzw. -klemmen für die zugehörigen Stromleitungen und ausgenommen die Nieten 8, besteht die Steckdose somit lediglich aus vier einstückigen Bauteilen. Der vordere, als Gehäuseteil ausgebildete Sockelteil 2, der hintere, als Gehäuseteil ausgebildete Sockelteil 3 und/oder das Abdeckglied 4 bestehen zweckmäßig aus einem harten Isolierwerkstoff, beispielsweise Steatit.As FIGS. 1 to 7 show, there is a device socket according to the invention, designed as a grill socket, which is used for connecting different grill radiators or other devices to be used in the household or in the oven, such as grill motors, forced-air fans or Like., Can be provided essentially from a two-part base 1 made of insulating material, which is designed as a housing. A cover member 4 is slidably mounted between the two base parts 2, 3 of the base 1. Current-carrying contacts 5 and a grounding contact 6 are provided in the base 1, and the two base parts 2, 3 are held together by two hollow rivets 8. The cover member is spring-loaded by a return spring 7 towards its cover position. Except for the current-carrying contacts 5 with the connecting members or terminals for the associated power lines, not shown, and except for the rivets 8, the socket thus consists of only four one-piece components. The front base part 2, which is designed as a housing part, the rear base part 3, which is designed as a housing part, and / or the cover member 4 expediently consist of a hard insulating material, for example steatite.

Der vordere Sockelteil 2 weist eine in Einbaulage in aller Regel vertikale Wandung 9 auf, welche an der Vorderseite von einem Flanschansatz 10 derart überragt wird, daß die Vorderseite der Wandung 9 die Bodenfläche einer Versenkung 11 bildet, deren Umrißform in Vorderansicht langrund mit horizontaler Längserstreckung ist. Gegen die Rückseite der Wandung 9 ist mit den Nieten 8 der weniger hohe hintere Sockelteil 3 gespannt, in dem drei nebeneinander liegende Öffnungen 12 für die Aufnahme der metallischen Kontakte 5 und des Erdungskontaktes 6 vorgesehen sind. Fluchtend zu jedem der Kontakte 5 und zum Erdungskontakt 6 ist in der Wandung 9 eine Steckeröffnung 13, 14 in Form eines Durchbruches vorgesehen, wobei die Mittelachsen der Steckeröffnungen 13, 14 in einer gemeinsamen, zur Wandung 9 rechtwinkligen Axialebene 15 liegen, die gleichzeitig die Längsmittelebene der Versenkung 11 ist und in Einbaulage horizontal liegt.The front base part 2 has in the installed position, as a rule, vertical wall 9, which is surmounted at the front by a flange shoulder 10 in such a way that the front of the wall 9 forms the bottom surface of a countersink 11, the outline shape of which is long in the front view with a horizontal longitudinal extension . Against the rear of the wall 9 is clamped with the rivets 8 the less high rear base part 3, in which three adjacent openings 12 for receiving the metallic contacts 5 and the grounding contact 6 are provided hen are. Aligned with each of the contacts 5 and the grounding contact 6, a plug opening 13, 14 in the form of an opening is provided in the wall 9, the central axes of the plug openings 13, 14 lying in a common axial plane 15 perpendicular to the wall 9, which at the same time is the longitudinal center plane the recess 11 is and is horizontal in the installed position.

Die drei Steckeröffnungen 13, 14 haben gleiche Abstände voneinander, wobei die beiden äußeren, den stromführenden Kontakten 5 zugeordneten Steckeröffnungen 13 zylindrisch sind. Die dem Erdungskontakt 6 zugehörige Steckeröffnung 14 ist durch das Ende eines nutartigen Schlitzes 16 gebildet, welcher die Wandung 9 bis zu einer, vorzugsweise bis zur unteren Längsbegrenzung der Versenkung 11 durchsetzt. Der Schlitz 16 ist im Flanschansatz 10 als konstant breite, zur Rückseite des vorderen Sockelteiles 2 offene Nut fortgesetzt. Diese Nut durchsetzt die zugehörige, quer bzw. rechtwinklig zu ihrer Längsrichtung liegende Außenfläche 17 des vorderen Sockelteiles 2. ZurVorderseite der Wandung 9 hin sind die Steckeröffnungen 13, 14 zum leichten Einführen des Steckers trichterartig erweitert. Die Steckrichtung Pfeil 18 der Steckdose liegt parallel zu den Steckeröffnungen 13, 14 und damit rechtwinklig zur Wandung 9.The three plug openings 13, 14 have the same spacing from one another, the two outer plug openings 13 assigned to the current-carrying contacts 5 being cylindrical. The plug opening 14 associated with the grounding contact 6 is formed by the end of a groove-like slot 16 which penetrates the wall 9 up to one, preferably up to the lower longitudinal limit of the recess 11. The slot 16 is continued in the flange shoulder 10 as a constantly wide groove open to the rear of the front base part 2. This groove passes through the associated outer surface 17 of the front base part 2 lying transversely or at right angles to its longitudinal direction. Towards the front of the wall 9, the plug openings 13, 14 are funnel-shaped for easy insertion of the plug. The plug direction arrow 18 of the socket is parallel to the plug openings 13, 14 and thus at right angles to the wall 9.

In der ansonsten nahezu über seine ganze Höhe durchgehend ebenen Rückseite des vorderen Sockelteiles 2, an welcher der hintere Sockelteil 3 anliegt, ist eine in Ansicht annähernd rechteckige Vertiefung 19 vorgesehen ; deren ebene und zur Rückseite parallele Bodenwandung ist von den Steckeröffnungen 13, 14 durchsetzt. Die Vertiefung 19 reicht etwa von den Steckeröffnungen 13, 14 bis zur Außenfläche 17 des vorderen Sockelteiles 2. Die seitlichen Begrenzungsflächen 20 der Vertiefung 19 liegen parallel zueinander und in Ansicht auf die Steckeröffnungen 13, 14 seitlich außerhalb der voneinander abgekehrten Außenbegrenzungen der beiden äußeren Steckeröffnungen 13. Die der Außenfläche 17 gegenüberliegende Begrenzungsfläche 21 der Vertiefung 19 liegt parallel zur Axialebene 15, etwa derart, daß sie in Ansicht gemäß Fig. 1 die Steckeröffnungen 13,14 an der von der Außenfläche 17 abgekehrten Seite tangential berührt.In the otherwise almost continuous entire back of the front base part 2, against which the rear base part 3 rests, an approximately rectangular recess 19 is provided in view; the flat and parallel to the rear bottom wall is penetrated by the plug openings 13, 14. The recess 19 extends approximately from the plug openings 13, 14 to the outer surface 17 of the front base part 2. The lateral boundary surfaces 20 of the recess 19 are parallel to one another and, in view of the plug openings 13, 14, laterally outside the mutually facing outer boundaries of the two outer plug openings 13 The boundary surface 21 of the recess 19 opposite the outer surface 17 lies parallel to the axial plane 15, approximately such that in the view according to FIG. 1 it touches the plug openings 13, 14 tangentially on the side facing away from the outer surface 17.

In die Vertiefung 19 ist das im wesentlichen rechteckig plattenförmige Abdeckglied 4 eingesetzt, dessen vier Ecken abgerundet sind und dessen Dicke etwa gleich der Tiefe der Vertiefung 19 ist. Die Länge des Abdeckgliedes 4 ist um das notwendige Bewegungsspiel kleiner als der Abstand zwischen den seitlichen Begrenzungsflächen 20 der Vertiefung 19, so daß es mit seinen seitlichen Plattenkanten 22 an den Begrenzungsflächen 20 geführt werden kann. Die Höhe des Abdeckgliedes 4 entspricht etwa dem Abstand zwischen der Begrenzungsfläche 21 und der Außenfläche 17. Die der Begrenzungsfläche 21 gegenüberliegende bzw. benachbarte Außenkante 23 des Abdeckgliedes 4 liegt parallel zur Begrenzungsfläche 21.The substantially rectangular plate-shaped cover member 4 is inserted into the recess 19, the four corners of which are rounded and the thickness of which is approximately equal to the depth of the recess 19. The length of the cover member 4 is smaller than the distance between the lateral boundary surfaces 20 of the recess 19 by the necessary play, so that it can be guided with its lateral plate edges 22 on the boundary surfaces 20. The height of the cover member 4 corresponds approximately to the distance between the boundary surface 21 and the outer surface 17. The outer edge 23 of the cover member 4 opposite or adjacent to the boundary surface 21 is parallel to the boundary surface 21.

In der Mitte seiner Länge ist das ansonsten plattenförmige Abdeckglied 4 durch einen über seine Vorderfläche vorstehenden mittleren, im Querschnitt rechteckigen Steg 24 verdickt. Der Steg 24 steht über die Vorderfläche des Abdeckgliedes 4 etwa um die Dicke vor, welche die Wandung 9 im Bereich der Stecköffnungen 13, 14 hat. Der Steg 24, der annähernd über die Höhe des Abdeckgliedes 4 durchgeht und über dessen untere Längskante geringfügig vorsteht, ist an den Schlitz 16 derart angepaßt, daß er in diesen Schlitz mit dem notwendigen Bewegungsspiel eingreift.In the middle of its length, the otherwise plate-shaped cover member 4 is thickened by a central web 24, which is rectangular in cross-section and projects beyond its front surface. The web 24 protrudes over the front surface of the cover member 4 by approximately the thickness which the wall 9 has in the region of the plug openings 13, 14. The web 24, which passes approximately over the height of the cover member 4 and protrudes slightly over its lower longitudinal edge, is adapted to the slot 16 such that it engages in this slot with the necessary play.

Das Abdeckglied 4 ist rechtwinklig zur Axialebene 15 in den Pfeilrichtungen 25 und 26 im Sockel 1 und damit gegenüber den Stecköffnungen 13, 14 verschiebbar. In dem zur längsseitigen Außenkante 23 benachbarten Endbereich ist der Steg 24 mit einer schrägen Auflauffläche 27 versehen, welche mit der Axialebene 15 einen sich zur Vorderseite der Wandung 9 öffnenden Winkel von etwa 45° einschließt. Die Auflauffläche 27 geht kontinuierlich und ebenengleich in eine Anfasung 28 über, welche an der Vorderseite des Abdeckgliedes 4 entlang der Außenkante 23 vorgesehen ist.The cover member 4 can be displaced at right angles to the axial plane 15 in the arrow directions 25 and 26 in the base 1 and thus relative to the plug openings 13, 14. In the end region adjacent to the longitudinal outer edge 23, the web 24 is provided with an oblique run-up surface 27 which, with the axial plane 15, encloses an angle of approximately 45 ° which opens towards the front of the wall 9. The run-up surface 27 merges continuously and at the same level into a chamfer 28 which is provided on the front of the cover member 4 along the outer edge 23.

Über die Außenfläche 17 stehen zwei Ansätze 29 des vorderen Sockelteiles 2 vor, die in Ansicht gemäß Fig. 1 beiderseits der Vertiefung 19 liegen und deren einander zugekehrte Innenflächen Fortsetzungen der seitlichen Begrenzungsflächen 20 der Vertiefung 19 bilden können. In diesen Ansätzen 29 ist jeweils ein taschenförmiger Schlitz 30 vorgesehen, der nur zur Vorderseite und zur Innenseite des jeweiligen Ansatzes 29 hin offen ist. In die Schlitze 30 der mit der Vorderseite und der Rückseite der Wandung 9 fluchtenden Ansätze 29 ist die im entspannten Zustand bogenförmig gekrümmte Rückstellfeder 7 mit ihren Enden eingesetzt. Zwischen diesen Enden liegt die Rückstellfeder 7 mit ihrer im entspannten Zustand konvexen Krümmungsseite an der von der Aufläuffläche 27 .abgekehrten Endfläche 31 des Steges 24 außerhalb des Sockels 1 mit Vorspannung an. Durch die Rückstellfeder 7 wird das Abdeckglied 4 derart in den Sockel 1 gedrückt, daß es mit seiner im Querschnitt abgerundeten oder beiderseits angefasten Außenkante 23 an der Begrenzungsfläche 21 der Vertiefung 19 anschlagbegrenzt anliegt und hierbei sowohl die Steckeröffnungen 13 von der Rückseite der Wandung 9 her durch den Plattenkörper als auch die Stecköffnung 14 durch den Steg 24 verschlossen und somit die Kontakte 5 und der Erdungskontakt 6 zur Vorderseite der Steckdose hin isoliert abgeschirmt sind.Above the outer surface 17 are two projections 29 of the front base part 2 which, in the view according to FIG. 1, lie on both sides of the recess 19 and whose mutually facing inner surfaces can form continuations of the lateral boundary surfaces 20 of the recess 19. In these lugs 29 there is a pocket-shaped slot 30, which is only open to the front and to the inside of the respective lug 29. In the slots 30 of the lugs 29 aligned with the front and the rear of the wall 9, the restoring spring 7, which is curved in the relaxed state, is inserted with its ends. Between these ends, the return spring 7 rests with its convex side in the relaxed state on the end surface 31 of the web 24 facing away from the run-up surface 27 outside the base 1 with prestress. By the return spring 7, the cover member 4 is pressed into the base 1 in such a way that its outer edge 23, which is rounded in cross-section or chamfered on both sides, bears against the limiting surface 21 of the recess 19 and thereby both the plug openings 13 from the rear of the wall 9 the plate body and the plug opening 14 are closed by the web 24 and thus the contacts 5 and the ground contact 6 are shielded from the front of the socket.

Der der Steckdose zugehörige, in den Figuren 2, 3 und 7 strichpunktiert angedeutete Stecker 32 weist drei den Stecköffnungen 13, 14 zugehörige. zueinander parallele und in einer gemeinsamen Axialebene liegende Steckerstifte 33, 34 auf, von welchen der dem Erdungskontakt 6 zugehörige mittlere Steckerstift 34 geringfügig länger als die beiden anderen gleichlangen Steckerstifte 33 für die stromführenden Kontakte 5 ist. Die Steckerstifte 33, 34 sind an einem Isolierträger 35 angeordnet, dessen Umriß - in Steckrichtung Pfeil 18 gesehen - nur geringfügig kleiner als die Versenkung 11 und dessen Erstreckung in Steckrichtung Pfeil 18 geringfügig größer als die Tiefe der Versenkung 11 ist.The plug 32 belonging to the socket, indicated by dash-dotted lines in FIGS. 2, 3 and 7, has three plug openings 13, 14 belonging to it. parallel to one another and lying in a common axial plane on connector pins 33, 34, of which the middle connector pin 34 associated with the grounding contact 6 is slightly longer than the two other connector pins 33 of the same length for the current-carrying contacts 5. The plugs Pins 33, 34 are arranged on an insulating support 35, the outline of which - seen in the direction of insertion arrow 18 - is only slightly smaller than the recess 11 and its extension in the direction of insertion arrow 18 is slightly greater than the depth of the recess 11.

An der von den Steckerstiften 33, 34 abgekehrten Seite des Isolierträgers 35 ist eine über den Umriß des Isolierträgers 35 vorstehende Tragplatte 36 befestigt, die elektrisch leitend mit dem Steckerstift 34 verbunden und gegenüber den Steckerstiften 33 isoliert angeordnet ist. Die Tragplatte 36 trägt die Enden eines Grillheizkörpers 37, welcher durch Einstecken des Steckers 32 in die Steckdose sowohl elektrisch angeschlossen als auch mechanisch gehaltert wird. Die Steckdose ihrerseits wird mit dem Flanschansatz 10 derart befestigt, daß nur der Flanschansatz frei liegt.On the side of the insulating carrier 35 facing away from the connector pins 33, 34, a support plate 36 protruding beyond the outline of the insulating carrier 35 is fastened, which is connected in an electrically conductive manner to the connector pin 34 and is insulated from the connector pins 33. The support plate 36 carries the ends of a grill heater 37, which is both electrically connected and mechanically held by inserting the plug 32 into the socket. The socket in turn is fastened with the flange extension 10 such that only the flange extension is exposed.

Wird der Stecker 32 in die Steckdose eingeführt, so gelangt zuerst die kugelkalottenförmig abgerundete oder kegelstumpfförmig verjüngte Endfläche des mittleren Steckerstiftes 34 in Berührung mit der Auflauffläche 27, während die Enden der Steckerstifte 33 noch im Abstand von dem Abdeckglied 4 liegen. Beim Anpressen des mittleren Steckerstiftes 34 gegen die Auflauffläche 27 des Abdeckgliedes 4 wird dieses entgegen der Kraft der Rückstellfeder 7 in Richtung Pfeil 25 nach unten gedrückt, bis die Umfangsfläche des mittleren Steckerstiftes 34 gemäß Fig. 7 auf die Außenkante 23 des Abdeckgliedes 4 gelangt ist; auch hierbei liegen die Steckerstifte 33 noch im Abstand von dem Abdeckglied 4, und zwar gemäß Fig. 7 etwa an den äußeren Enden der zugehörigen Stecköffnungen 13. In dieser Lage ist der Abstand zwischen dem Isolierträger 35 und der Vorderseite des Flanschansatzes 10 bereits so gering, daß mit einem Finger nicht mehr in die Versenkung 11 gegriffen werden kann.If the plug 32 is inserted into the socket, the spherical cap-shaped or frustoconically tapered end surface of the middle plug pin 34 first comes into contact with the run-up surface 27, while the ends of the plug pins 33 are still at a distance from the cover member 4. When pressing the middle plug pin 34 against the run-up surface 27 of the cover member 4, the latter is pressed downward in the direction of arrow 25 against the force of the return spring 7 until the peripheral surface of the middle plug pin 34 according to FIG. 7 has reached the outer edge 23 of the cover member 4; here, too, the connector pins 33 are still at a distance from the cover member 4, specifically according to FIG. 7 at the outer ends of the associated plug openings 13. In this position, the distance between the insulating support 35 and the front of the flange extension 10 is already so small, that can no longer be reached with a finger in the recess 11.

Bei weiterem Einschieben kommt zuerst der Steckerstift 34 in Berührung mit dem Erdungskontakt 6, wobei bereits in dieser Lage die Vorderfläche des lsolierträgers 35 schließend vor der vorderen offenen Seite der Versenkung 11 liegt hierbei gelangen die Steckerstifte 33 ggf. ebenfalls in Berührung mit dem Abdeckglied 4, und zwar im Bereich der Anfasung 28, so daß sie ggf. das Abdeckglied '4 entgegen der Kraft der Rückstellfeder 7 noch um ein kleines Stück zurückschieben können, um zu den stromführenden Kontakten 5 vorzudringen. Mit letzteren kommen die Steckerstifte 33 erst in Kontakt, wenn der Isolierträger 35 bereits in die Versenkung 11 eingreift und damit die Steckerstifte 33 über ihre gesamte Länge nach außen hermetisch abgeschirmt sind. Wird danach der Stecker 32 wieder herausgezogen, so springt das Abdeckglied 4 unter der Kraft der Rückstellfeder 7 in Richtung Pfeil 26 in seine beschriebene Abdeckstellung zurück.With further insertion, the plug pin 34 comes into contact with the ground contact 6, the front surface of the insulating support 35 closing in front of the front open side of the recess 11 already in this position, the plug pins 33 possibly also come into contact with the cover member 4, specifically in the area of the chamfer 28, so that, if necessary, they can still push the cover member 4 a small distance against the force of the return spring 7 in order to advance to the current-carrying contacts 5. The connector pins 33 only come into contact with the latter when the insulating carrier 35 already engages in the recess 11 and the connector pins 33 are thus hermetically shielded from the outside over their entire length. If the plug 32 is then pulled out again, the cover member 4 springs back under the force of the return spring 7 in the direction of arrow 26 into its cover position described.

In den Figuren 8 bis 11 sind für einander entsprechende Teile die gleichen Bezugszeichen wie in den Figuren 1 bis 7, jedoch mit dem Index « a verwendet.In FIGS. 8 to 11, the same reference numerals as in FIGS. 1 to 7, but with the index “a, are used for corresponding parts.

Bei der in den Figuren 8 bis 11 gegenüber den Figuren 1 bis 7 vergrößert dargestellten Geräte-Steckdose ist die Auflauffläche 27a des Abdeckgliedes 4a im Querschnitt an den zugehörigen Teil des Querschnittes des zugehörigen Steckerstiftes 34a des Steckers 32a angepaßt und daher im dargestellten Ausführungsbeispiel im Querschnitt konkav ausgerundet rinnenförmig. Diese rinnenförmige Auflauffläche 27a ist geringfügig schmaler als der Steg 24a, so daß die Seitenbegrenzungen der Auflauffläche 27a mit geringem Abstand von den Seitenflächen des Steges 24a liegen. Durch diese Ausbildung kann ein noch leichtgängigeres Gleiten des Steckerstiftes 34a beim Einstecken des Steckers 32a in die Steckdose erzielt werden.In the case of the device socket shown in FIGS. 8 to 11, enlarged compared to FIGS. 1 to 7, the run-up surface 27a of the cover member 4a is adapted in cross section to the associated part of the cross section of the associated plug pin 34a of the plug 32a and is therefore concave in cross section in the exemplary embodiment shown rounded trough-shaped. This channel-shaped run-up surface 27a is slightly narrower than the web 24a, so that the side boundaries of the run-up surface 27a lie at a short distance from the side surfaces of the web 24a. This configuration enables the plug pin 34a to slide even more smoothly when the plug 32a is inserted into the socket.

Die der Endfläche 31a zugehörige Außenbegrenzung 38 des Abdeckgliedes 4a schließt beiderseits des Steges 24a unmittelbar an dessen Endfläche 31a an und verläuft von diesem Anschluß jeweils spitzwinklig zur Außenkante 23a, derart, daß die beiden beiderseits des Steges 24a liegenden Abschnitte der Außenbegrenzung 38a unter einem stumpfen Winkel von nur geringfügig weniger als 180° zueinander liegen. In der Abdeckstellung schließt die Endfläche 31a bündig bzw. ebenengleich mit der Außenfläche 17a des Sockels 1a ab, wobei jedoch die Anordnung so getroffen ist, daß die Rückstellfeder 7a wenigstens geringfügig in die das Abdeckglied 4a aufnehmende Gehäuseöffnung eintreten kann.The outer boundary 38 of the cover member 4a associated with the end face 31a directly adjoins the end face 31a on both sides of the web 24a and extends from this connection at an acute angle to the outer edge 23a, such that the two sections of the outer boundary 38a lying on both sides of the web 24a are at an obtuse angle of only slightly less than 180 ° to each other. In the cover position, the end surface 31a is flush or level with the outer surface 17a of the base 1a, but the arrangement is such that the return spring 7a can at least slightly enter the housing opening receiving the cover member 4a.

Die Rückstellfeder 7a ist an einer Längskante mit einem winkelförmigen, einteilig mit ihr ausgebildeten Ansatz 39 versehen, dessen freier Schenkel eine aufgerichtete Lasche 40 bildet. Bei in eine Ebene gedrückter Rückstellfeder 7a liegt der andere Schenkel des Ansatzes 39 in der Ebene der Rückstellfeder und die gleich breite Lasche 40 rechtwinklig hierzu. Bei entspannter Rückstellfeder 7a steht die gegenüber dem Steg 24a nur geringfügig schmalere Lasche 40 über die konvexe Krümmungsseite der Rückstellfeder vor. Der Abstand zwischen der Lasche 40 und der gegenüberliegenden Längskante der Rückstellfeder 7a ist nur geringfügig kleiner als die Dicke des Abdeckgliedes 4a im Bereich des Steges 24a. In montiertem Zustand hintergreift die Rücksteilfeder 7a das Abdeckglied 4a an dessen Rückseite, wobei der Ansatz 39 an der Endfläche 31a anliegt. In der Vorderfläche des hinteren Sockelteiles 3a, die zur Führung der Rückseite des Abdeckgliedes 4a dient, ist eine an der Unterseite offene Tasche 41 als Aufnahmeöffnung für die Lasche 40 in der Abdeckstellung des Abdeckgliedes 4a vorgesehen. Dadurch ist die Rückstellfeder 7a in der Abdeckstellung der Steckdose zusätzlich geschützt.The return spring 7a is provided on one longitudinal edge with an angular projection 39, which is formed in one piece with it, the free leg of which forms an erected tab 40. When the return spring 7a is pressed into a plane, the other leg of the extension 39 lies in the plane of the return spring and the tab 40 of the same width is at right angles thereto. When the return spring 7a is relaxed, the tab 40, which is only slightly narrower than the web 24a, projects beyond the convex curvature side of the return spring. The distance between the tab 40 and the opposite longitudinal edge of the return spring 7a is only slightly smaller than the thickness of the cover member 4a in the region of the web 24a. In the assembled state, the rear part spring 7a engages behind the cover member 4a on its rear side, the shoulder 39 abutting the end face 31a. In the front surface of the rear base part 3a, which serves to guide the rear of the cover member 4a, a pocket 41 open on the underside is provided as a receiving opening for the tab 40 in the cover position of the cover member 4a. As a result, the return spring 7a is additionally protected in the cover position of the socket.

In Fig. 8 ist des weiteren einer der Kontakte, nämlich der Erdungskontakt 6a, erkennbar, der in der Öffnung 12a des hinteren Sockelteiles 3a liegt und im wesentlichen durch eine mit einer Federklammer 42 versehene Klemmbuchse gebildet ist, die an der Oberseite des Sockels 1a eine von außen frei zugängliche Anschlußklemme 43 aufweist.In Fig. 8, one of the contacts, namely the ground contact 6a, can be seen, which lies in the opening 12a of the rear base part 3a and is essentially formed by a spring bushing 42 which is provided on the top of the base 1a Terminal 43 freely accessible from the outside.
