Description

Die Erfindung betrifft eine elektrische als Schutzkontaktsteckdose ausgebildete Doppelsteckdose mit einem gemeinsamen Sockel mit je zwei Steckkontakten für die Leiterpole sowie mit zwei etwa U-förmigen Schutzleiterkontakten mit Schutzkontaktfederbügeln für den Schutzleiter.The invention relates to an electrical socket designed as a protective contact Double socket with a common base with two plug contacts for each Conductor poles and two approximately U-shaped protective conductor contacts with protective contact spring clips for the protective conductor.

Elektrische Steckdosen, die als Einfach- oder Doppelsteckdose ausgebildet und jeweils mit Schutzkontaktfederbügeln versehen sind, sind allgemein bekannt. Bei Einfach-Steckdosen ist üblicherweise jeweils ein Sockel vorgesehen, in welchem die für den elektrischen Anschluß erforderlichen Anschlußklemmen ebenso untergebracht sind wie die Steckkontakte für die hierin eingreifenden Steckerstifte des jeweiligen Steckers. Außerdem nimmt der Sockel auch Schutzkontaktfederbügel auf, welche den eingesteckten Stecker jeweils seitlich federnd beaufschlagen und hierbei kontaktieren.Electrical sockets that are designed as single or double sockets and are each provided with protective contact spring clips are generally known. At Single sockets are usually provided with a base in each the terminals required for the electrical connection are also housed are like the plug contacts for the engaging pins of the respective plug. The base also takes protective contact spring clips on, which act on the inserted plug laterally and contact here.

Diese Federbügel dienen als sicherheitsrelevantes Bauteil und müssen daher sicher im Sockel verankert sein. Dabei ist zu berücksichtigen, daß die Schutzkontaktfederbügel exakt ausgerichtet sind. Dies führt bei der Herstellung von Schutzkontaktfederbügeln für Doppelsteckdosen zu Problemen und aufwendigen Maßnahmen, zum Beispiel Verschweißen der zwei Einzelkontaktfedern miteinander oder aufwendige Biegungen. Darüberhinaus entsteht bei den bekannten Schutzkontaktfederbügeln eine beträchtliche Menge an Abfall durch Verschnitt. These spring clips serve as a safety-relevant component and must therefore be safe be anchored in the base. It should be noted that the protective contact spring clip are exactly aligned. This leads to the manufacture of protective contact spring clips for double sockets to problems and complex measures, for example welding the two individual contact springs together or elaborate bends. In addition, the known protective contact spring clips are produced a significant amount of waste from waste.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Steckdose der eingangs genannten Art zu schaffen, deren elektrische Schutzleiterkontakte möglichst einfach hergestellt sind, wobei ein Minimum an Verschnitt resultiert, sowie ein Verfahren zu ihrer Herstellung anzugeben.Based on this prior art, it is an object of the invention to To create a socket of the type mentioned, whose electrical protective conductor contacts are made as simply as possible, resulting in a minimum of waste, and to specify a process for their production.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the characterizing features of Claim 1 solved. Further advantageous refinements and improvements the invention are the subject of the dependent claims.

Dementsprechend sind die beiden Schutzkontaktfederbügel einstückig miteinander verbunden, wobei die Federbügel jeweils frei von der jeweiligen Basis des U-förmigen Schutzleiterkontakts abgehen und so ohne gegenseitige Beeinflussung bleiben.Accordingly, the two protective contact spring clips are in one piece with one another connected, the spring clips each free from the respective base of the U-shaped Protective conductor contact come off and so without mutual interference stay.

Da die beiden Schutzleiterkontakte, wie angegeben, aus einem gemeinsamen Blechstreifen herausgearbeitet sind, können aufwendige Schweiß- oder Lötoperationen sowie die unerläßlichen Richtarbeiten zur Verbindung der einzelnen Schutzleiterkontakte entfallen.Since the two protective conductor contacts, as stated, come from a common Sheet metal strips are worked out, can be complex welding or soldering operations as well as the essential straightening work to connect the individual Protective conductor contacts are omitted.

Entsprechend einer bevorzugten Ausführungsform der Erfindung sind die beiden Schutzkontaktfederbügel durch einen einstückig angeformten Steg miteinander verbunden, wobei vorteilhafterweise der die beiden U-förmigen Schutzleiterkontakte miteinander verbindende Steg an deren Basis angeformt ist.According to a preferred embodiment of the invention, the two are Earthing contact spring clip by means of a web integrally formed with one another connected, advantageously the two U-shaped protective conductor contacts connecting web is integrally formed on the base.

Bei einem fertig geformten Doppel-Schutzleiterkontakt entsprechend der Erfindung sind die beiden einzelnen aus dem gemeinsamen Blechstreifen herausgestanzten und gebogenen Schutzleiterkontakte derart zueinander versetzt, daß der verbindende Steg S-förmig gekrümmt ist, wobei seine freien Enden jeweils an der Basis eines Schutzleiterkontakts anschließen. Dabei entspricht die Länge des verbindenden Steges etwa der Breite der Basis eines Schutzleiterkontakts.With a fully formed double protective conductor contact according to the invention are the two individual punched out of the common sheet metal strip and bent protective conductor contacts so offset that the connecting Web is S-shaped, its free ends each at the base of a protective conductor contact. The length of the connecting corresponds Ridges approximately the width of the base of a protective conductor contact.

Ein erfindungsgemäßes Verfahren zur Herstellung einer elektrischen Doppelsteckdose mit Schutzleiterkontakten nach einem der vorherigen Ansprüche mit einem gemeinsamen Sockel mit je zwei Steckkontakten für die Leiterpole sowie mit zwei etwa U-förmigen Schutzkontaktfederbügeln für den Schutzleiter ist dadurch gekennzeichnet, daß die beiden Schutzkontaktfederbügel als Stanz-Biege-Preß-Teil gemeinsam aus einem einzigen Blechstreifen hergestellt werden. Hierbei sind die nachfolgenden Arbeitsschritte in der angegebenen Reihenfolge vorgesehen.A method according to the invention for producing an electrical double socket with protective conductor contacts according to one of the preceding claims with a common base with two plug contacts each for the conductor poles and two about U-shaped protective contact spring clips for the protective conductor is characterized that the two protective contact spring clips as a punch-bend-press part can be produced together from a single sheet metal strip. Here are the subsequent steps in the order given.

In einem ersten Schritt wird aus dem für die Herstellung des Schutzleiterkontakts vorgesehenen Blechstreifen ein Rohling herausgestanzt. Dabei befindet sich die Basis des einen später U-förmigen Schutzleiterkontakts in einer ersten Ebene während die Basis des anderen später U-förmigen Schutzleiterkontakts in einer zweiten Ebene parallel versetzt zu der ersten Ebene verläuft. Ferner sind beide gleichzeitig aus demselben Blechstreifen gestanzten Rohlinge durch einen Steg miteinander verbunden.In a first step, it is used to produce the protective conductor contact provided blank sheet metal punched out a blank. Here is the Basis of the later U-shaped protective conductor contact on a first level while the base of the other later U-shaped protective conductor contact in one second level runs parallel to the first level. Furthermore, both are blanks simultaneously punched from the same sheet of metal through a web connected with each other.

Dieser Doppel-Rohling weist bereits die Profilierung der späteren Schutzkontaktfederbügel auf. Beim Stanzvorgang wird nämlich die Endkontur der Schutzkontaktfederbügel erzeugt, wobei in den Zwischenräumen zwischen den späteren Bügeln das dort nicht benötigte Material herausgeschnitten und entfernt wird.This double blank already has the profile of the later protective contact spring clip on. During the punching process, the end contour of the protective contact spring clip becomes generated, being in the spaces between the later temples the material not required there is cut out and removed.

Anschließend erhalten die Schutzkontaktfederbügel ihre endgültige Formgebung, indem sie in eine U- Form gebogen werden. Bis hierher ähneln die Fertigungsschritte der herkömmlichen Fertigung eines Einzel- Schutzleiterkontakts.The protective contact spring clips then receive their final shape, by bending them into a U shape. Up to this point, the manufacturing steps are similar the conventional manufacture of a single protective conductor contact.

In einem dritten Verfahrensschritt werden die durch einen Steg miteinander verbundenen Schutzleiterkontakte aufeinander ausgerichtet, indem die Basis des einen U-förmigen Schutzkontaktfederbügels in die Ebene des anderen Schutzkontaktfederbügels parallel versetzt wird. Hierdurch erhält der die beiden Schutzkontaktfederbügel verbindende Verbindungssteg seine charakteristische S-Form.In a third process step, the are connected to each other by a web Protective conductor contacts aligned with each other by the base of one U-shaped protective contact spring clip in the plane of the other protective contact spring clip is offset in parallel. This gives the two protective contact spring clips connecting bridge has its characteristic S-shape.

Im Hinblick auf eine kompakte Gestaltung ist der Sockel der Doppelsteckdose ebenfalls kompakt gestaltet, das heißt, er erstreckt sich nicht über die gesamte Länge, die üblicherweise zwei benachbart angeordnete Steckdosen erreichen, sondern er ist kürzer vorgesehen. Die üblicherweise mittig angeordneten Steckkontakte für die Steckerstifte sind dementsprechend jeweils randnah an den Enden angeordnet. Hierdurch bedingt weicht die Gestaltung der Basis jeder der beiden Schutzleiterkontakte der Doppelsteckdose von der üblichen Gestaltung für Schutzleiterkontakte von Einzelsteckdosen insofern ab, als jede Basis des U-förmigen Schutzleiterkontakts nach außen hin stufenförmig gekröpft ist. Während die Basis zunächst auf dem Niveau der Sockeloberkante verläuft, weist sie bei Erreichen des zugeordneten Endes des Sockels einen stufenförmigen Versatz nach oben auf.In terms of a compact design, the base of the double socket also compact, which means that it does not extend over the entire area Length that usually reaches two adjacent sockets, it is intended to be shorter. The usually centrally located plug contacts for the connector pins are accordingly close to the edges at the ends arranged. As a result, the design of the base of each of the two differs Protective conductor contacts of the double socket of the usual design for protective conductor contacts from individual sockets in that each base of the U-shaped Protective conductor contact is cranked step-like towards the outside. While the base initially runs at the level of the upper edge of the base, it points when the associated end of the base up a step-shaped offset.

Diese und weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.These and other advantageous refinements and developments of the invention are marked in the subclaims.

In Fig. 1 ist eine Schrägansicht eines Doppel-Schutzleiterkontakts 10 gemäß der Erfindung dargestellt, der aus zwei Einzel- Schutzleiterkontakten 12, 14 gebildet ist, welche mittels eines Steges 16 miteinander verbunden sind.In Fig. 1 is an oblique view of a double protective conductor contact 10 according to the Invention shown, which is formed from two individual protective conductor contacts 12, 14, which are connected to one another by means of a web 16.

Anhand der in Fig. gezeigten Darstellung ist die enge benachbarte Anordnung der beiden Einzel- Schutzleiterkontakte 12, 14 gut zu erkennen. Jeder der beiden Einzel- Schutzleiterkontakte 12, 14 besitzt eine Basis 18, an welcher der Steg 16 jeweils anschließt, sowie jeweils zwei Schutzkontaktfederbügel 20, 22. Based on the representation shown in Fig. The close adjacent arrangement of the two individual protective conductor contacts 12, 14 can be clearly seen. Each of the two individual protective conductor contacts 12, 14 has a base 18 on which the web 16 is in each case connects, as well as two protective contact spring clips 20, 22.

Die mittig aneinander angrenzenden Schutzkontaktfederbügel 20 sind annähernd rechtwinklig von der zugeordneten Basis 18 abgewinkelt und entsprechen in ihrer Formgebung herkömmlichen Schutzkontaktfederbügeln, wie sie üblicherweise bei Einzelsteckdosen paarweise zum Einsatz kommen.The protective contact spring clips 20, which adjoin one another in the center, are approximate angled at right angles from the associated base 18 and correspond in their Shaping conventional protective contact spring clips, as is usually the case with Single sockets are used in pairs.

Die außenliegenden Schutzkontaktfederbügel 22 sind stufig ausgebildet und zwar derart, daß ein erster Bereich 24 des Schutzkontaktfederbügels 22 sich ebenfalls etwa rechtwinklig von der Basis erstreckt. Etwa auf halber Höhe bezogen auf den mittig angeordneten Schutzkontaktfederbügel 20 ist ein zweiter Abschnitt 26 des Schutzkontaktfederbügels 22 horizontal nach außen geführt. Die Länge dieses horizontalen Abschnitts 26 addiert sich zur Länge der Basis 18 und entspricht mit dieser gemeinsam etwa dem Durchmesser eines in die Steckdose einzuführenden, hier nicht dargestellten Steckers. An den zweiten Abschnitt schließt sich ein dritter Abschnitt 28 an, der wiederum parallel versetzt zum ersten Abschnitt, rechtwinklig von der Basis 18 weggerichtet ist.The external protective contact spring clips 22 are designed in stages, namely such that a first region 24 of the protective contact spring clip 22 is also located extends approximately at right angles from the base. About halfway up the centrally arranged protective contact spring clip 20 is a second section 26 of the Earthing contact spring clip 22 guided horizontally outwards. The length of this horizontal Section 26 adds to the length of the base 18 and corresponds to this together about the diameter of a plug to be inserted into the socket connector not shown here. The third section is followed by a third Section 28 on, which in turn offset parallel to the first section, at right angles is directed away from the base 18.

Die freien Enden der Schutzkontaktfederbügel 20, 22 der beiden Einzel-Schutzleiterkontakte 12, 14 sind in üblicher Weise gestaltet, das heißt mit zu geschlossenen Ösen umgebogenen Kontaktfahnen 30 versehen.The free ends of the protective contact spring clips 20, 22 of the two individual protective conductor contacts 12, 14 are designed in the usual way, that is, with too closed Provide eyelets bent contact tabs 30.

In Fig. 2 ist ein Rohling 11 eines erfindungsgemäßen Schutzleiterkontakts in Draufsicht gezeigt, unmittelbar nach dem Ausstanzen aus einem entsprechenden Blechabschnitt. In diesem Stadium erstrecken sich noch alle später abgewinkelten Schutzkontaktfederbügel 20, 22 und Abschnitte 24, 26, 28 einschließlich der Kontaktfahnen 30 in einer gemeinsamen Ebene mit der Basis 18 und dem Verbindungssteg 16.2 shows a blank 11 of a protective conductor contact according to the invention in Top view shown, immediately after punching out a corresponding one Sheet metal section. At this stage, all later angled ones extend Earthing contact spring clip 20, 22 and sections 24, 26, 28 including the contact tabs 30 in a common plane with the base 18 and the connecting web 16.

In Fig. 3 weist der Rohling 11 gemäß Fig. 2 bereits abgewinkelte Schutzkontaktfederbügel 20, 22 auf. Gegenüber dem in Fig. gezeigten Fertigstadium befinden sich die beiden Einzel- Schutzleiterkontakte 12, 14 noch in jeweils unterschiedlichen Ebenen, das heißt die beiden Schutzleiterkontakte 12, 14 müssen noch, wie in Fig. 4 dargestellt, in eine gemeinsame Ebene versetzt werden. Da die übrigen Merkmale jeweils denen in den Figuren 1 und 2 entsprechen, sind diese ohne weitere Erklärung mit den entsprechenden Bezugsziffern versehen. In FIG. 3, the blank 11 according to FIG. 2 already has an angled protective contact spring clip 20, 22 on. Compared to the finished stage shown in FIG the two individual protective conductor contacts 12, 14 each in different Levels, i.e. the two protective conductor contacts 12, 14 must still, as in Fig. 4, are placed in a common plane. Because the other features correspond to those in Figures 1 and 2, these are without further explanation provided with the corresponding reference numbers.

In Fig. 5 ist eine Seitenansicht einer Variante eines Doppel-Schutzleiterkontakts 32 dargestellt, bei welcher die Schutzkontaktfederbügel 20, 22 an ihren freien Enden nicht mit geschlossen Kontaktösen sondern mit halboffenen Kontaktbügeln 34 versehen sind. Diese Formgebung erfordert einen geringeren Fertigungsaufwand ohne Nachteil für die Schutzleiterkontaktierung. Ferner wird aus dieser Darstellung die stufige Ausgestaltung der Basis 18 beziehungsweise der äußeren Schutzkontaktfederbügel 22 deutlich.5 is a side view of a variant of a double protective conductor contact 32 shown, in which the protective contact spring clips 20, 22 at their free ends not with closed contact eyelets but with semi-open contact clips 34 are. This shape requires less manufacturing effort without Disadvantage for the protective conductor contact. Furthermore, from this representation step configuration of the base 18 or the outer protective contact spring clip 22 clearly.
