Abstract

1. Socket strip with various pocket depths (13, 14) for plugs with different cross sections (8, 9), for example, earthing-pin plug, Euro flat plug etc. The pockets of different depths (13, 14) with engagements orifices (131, 132, 141, 142) for the plug pins (S 1, S 2) are arranged adjacently in the flat wall area of the socket strip (1). The pockets (13, 14) are matched to pairs of contact orifices (K 1, K 2) for the plug pins (S 1, S 2). The contact orifices (K 1, K 2) are located on spring-action contact strips (2, 3) inside the socket strip (1). The contact orifices (K 1, K 2) in the contact strips (2, 3) have U-form openings (K 11, K 21) offset 180 degrees alternately to correspond to the engagement orifices (131, 132, 141, 142) in the socket strip (1) and may be identified by the arrestors (4, 5, 6, 7) at the contact strips (2, 3) next to the adjacent or 180 degrees offset contact orifices (K 1, K 2). These arrestors prevent contact between neighbouring contact orifices (K 1, K 2) when the pins (S 1, S 2) of a plug (8, 9) ar inserted into the associated contact orifices (K 1, K 2).

Description

Die Erfindung betrifft eine Steckdosenleiste mit unterschiedlich gestalteten Vertiefungen für im Querschnitt unterschiedliche Steckerelemente wie Schutzkontakt-Stecker, Europa-Flachstecker und dgl., wobei die unterscniedlich gestalteten Vertiefungen mit ihren Eingriffsöffnungen für die Steckerstifte der Steckerelemente in ebenen Wandbereichen der Steckdosenleiste angeordnet sind und wobei den Vertiefungen im Abstand der Eingriffsöffnungen voneinander im Inneren der Steckdosenleiste federnde Metallschienen als Kontaktleisten mit einer Vielzahl von paarweise hintereinander angeordneten Kontaktöffnungen für die Steckerstifte der Steckerelemente zugeordnet sind.The invention relates to a power strip with differently designed recesses for different cross-section connector elements such as earthed plugs, European flat plug and the like at a distance from the engagement openings from one another in the interior of the power strip, resilient metal rails are assigned as contact strips with a plurality of contact openings arranged in pairs for the plug pins of the plug elements.

Aus dem.DE-GM 78 10 684 ist eine kombinierte Steckdosenleiste bekannt, die auch als Vielfachsteckdose bezeichnet wird. Diese Vielfachsteckdose kann in einem Gehäuseblock derart ausgebildet sein, daß die Vorderseite mit Vertiefungen für die Schutzkontakt-Stecker und die Rückseite .mit flach-rechteckigen Vertiefungen für die Europa-Flachstecker ausgelegt ist. Im Inneren des Gehäuseblockes sind sowohl der Vorderseite als auch der Rückseite jeweils gesonderte Kontaktleisten zugeordnet, was den Aufbau des Gehäuseblocks kompliziert. Außerdem wird der Gehäuseblock durch diese technische Notwendigkeit unhandlich.A combined power strip is known from DE-GM 78 10 684, which is also referred to as a multiple socket. This multiple socket can be designed in a housing block in such a way that the front is designed with recesses for the protective contact plug and the rear with flat rectangular recesses for the European flat plug. In the interior of the housing block, separate contact strips are assigned to both the front and the rear, which complicates the structure of the housing block. This technical necessity also makes the housing block unwieldy.

Aus der DE-OS 29 15 816 ist ferner eine elektrische Mehrfach-Steckdose bekannt, welche in jeweils einer einzigen Vertiefung Einsatzmöglichkeiten für Schutzkontakt-Stecker und für Europa-Flachstecker besitzt.From DE-OS 29 15 816 an electrical multiple socket is also known, which has possible uses for earthed plugs and for European flat plugs in a single recess.

Hier sind neben den Öffnungen für den Einsatz der Steckerstifte eines Schutzkontakt-Steckers jeweils nach beiden Seiten neben diesen Öffnungen weitere öffnungen für die Aufnahme der Steckerstifte von Europa-Flachsteckern vorhanden. So können in jeder Vertiefung entweder ein Schutzkontakt-Stecker oder zwei nebeneinander angeordnete Europa-Flachstecker angeordnet werden.In addition to the openings for the use of the plug pins of a protective contact plug, there are further openings on both sides next to these openings for receiving the plug pins of European flat plugs. Either a protective contact plug or two European flat plugs arranged side by side can be arranged in each recess.

Diese Mehrfach-Steckdose hat den Nachteil, daß der Schutzkontakt-Stecker aus der zugeordneten Vertiefung entnommen werden muß, wenn ein oder zwei Europa-Flachstecker an seine Stelle treten sollen.This multiple socket has the disadvantage that the protective contact plug must be removed from the associated recess if one or two European flat plugs are to take its place.

Aus der DE-OS 28 16 729 ist noch ein elektrisches Mehrfach-Steckverbindungsstück bekannt geworden, welches zum Einsetzen von zweipoligen Flachsteckern in Schutzkontakt-Steckdosen ausgelegt ist. Dieses Steckverbindungsstück kann als Übergangsstück bezeichnet werden, durch welches Schutzkontakt-Steckdosen zum Einsetzen von Europa-Flachsteckern geeignet werden. Auch hier können lediglich anstelle eines Schutzkontakt-Steckers über das Verbindungsstück einer oder zwei Europa-Flachstecker eingesetzt werden.From DE-OS 28 16 729 an electrical multiple connector has become known, which is designed for inserting two-pole tabs into protective contact sockets. This connector can be described as a transition piece, through which earthed sockets are suitable for inserting European flat plugs. Here too, only one or two European flat plugs can be used instead of a protective contact plug via the connecting piece.

Gegenüber diesem Stand der Technik hat sich die Erfindung die.Aufgabe gestellt, eine Steckdosenleiste zu sehaffen, bei der unterschiedliche Steckerelemente wechselseitig versetzt mit ihren Steckerstiften in die Kontaktöffnungen der paarig nebeneinander angeordneten Kontaktleisten eingesetzt werden können, ohne daß beim Einsatz des einen Steckerelementes das andere entfernt werden müßte, ohne daß im Innenraum der Steckdosenleiste zwei paarig hintereinander angeordnete Kontaktleisten verwendet werden müßten und ohne daß die in die Kontaktleisten eingeführten Steckerstifte eines Steckerelementes aus ihrem Klemmsitz in der Kontaktleiste gelöst werden müßten, wenn an die Stelle des einen Steckerelementes, z.B. des Schutzkontakt-Steckers, ein anderes Steckerelement, z.B. ein Europa-Flachstecker eingesetzt werden soll. Erfindungsgemäß wird dazu vorgeschlagen, daß die Kontaktöffnungen der Kontaktleisten abwechselnd mit ihren aufgekelchten Eingriffsbereichen den jeweils um 180° versetzten Eingriffsöffnungen der Steckdosenleiste in der Anzahl entsprechend der Steckergestaltung zugeordnet sind, und daß an den Kontaktleisten im Bereich der Kontaktöffnungen gegenüberliegend oder um 1800 versetzt, Sperrzungen vorgesehen sind, welche ein Auffedern benachbarter Kontaktöffnungen beim Einführen der Steckerstifte eines Steckerelementes in die zugeordneten Kontaktöffnungen verhindern.Compared to this prior art, the invention has set itself the task of providing a power strip in which different plug elements can be inserted with their plug pins alternately offset into the contact openings of the contact strips arranged in pairs next to one another, without removing the other when using one plug element would have to be without two contact strips arranged in pairs in the interior of the power strip would have to be used and without the plug pins of a plug element inserted into the contact strips having to be released from their clamp seat in the contact strip if another plug element, for example a European flat plug, is to be used in place of the one plug element, for example the protective contact plug . According to the invention it is proposed to the fact that the contact openings of the contact strips to each offset by 180 ° engaging holes of the socket strip alternately with their aufgekelchten engaging portions assigned in the number corresponding to the connector design, and in that added to the contact strips in the contact openings opposite or 180 0, locking tabs are provided which prevent springing open of adjacent contact openings when inserting the plug pins of a plug element into the associated contact openings.

Mit der erfindungsgemäßen Steckdosenleiste, die nur noch ein einziges Paar von Kontaktleisten in ihrem Innenraum besitzt, lassen sich Steckerstifte von unterschiedlich gestalteten Steckerelementen wechselseitig um 180° versetzt einsetzen, die ihren Klemmsitz in der Kontaktleiste auch dann behalten, wenn die Steckerstifte der einzelnen Steckerelemente unterschiedliche Dicken aufweisen. Das Problem des Herausfallens der Steckerstifte des einen Steckerelementes beim Einsetzen der Steckerstifte eines benachbarten Steckerelementes, wobei dieses Einsetzen um 180° versetzt, erfolgt, wird über die Erfindung durch die Sperrzungen im Bereich der Kontaktöffnungen gelöst. Diese Sperrzungen verhindern das Aufdrücken der Kontaktleisten mit der Folge der Vergrößerung benachbarter Kontaktöffnungen, so daß die dort bereits sitzenden Stekkerstifte unbehelligt in ihrem Klemmsitz gehaltert bleiben, obwohl in benachbarten Kontaktöffnungen weitere Steckerstifte in Klemmsitz gebracht werden.With the power strip according to the invention, which only has a single pair of contact strips in its interior, plug pins of differently designed plug elements can be used mutually offset by 180 °, which retain their press fit in the contact strip even if the plug pins of the individual plug elements have different thicknesses exhibit. The problem of the connector pins falling out of one connector element when inserting the connector pins of an adjacent connector element, this insertion being offset by 180 °, is solved by the invention through the locking tongues in the area of the contact openings. These locking tongues prevent the contact strips from being pressed open, with the consequence of the enlargement of adjacent contact openings, so that the plug pins already seated there remain undisturbed in their press fit ben, although additional connector pins are clamped in adjacent contact openings.

Mit der erfindungsgemäßen Lösung der Anordnung eines Kontaktleistenpaares innerhalb der Steckdosenleiste und der im Körper der Steckdosenleiste um 180° versetzten Eingriff$vertiefungen.für die Steckerelemente läßt sich vorteilhaft auch der Nachteil des bekannten Standes der Technik lösen, bei dem nämlich erst das eine Steckerelement entfernt werden mußte, bevor Steckerelemente anderer Gestaltung an dessen Platz eingesetzt werden konnten.With the solution according to the invention of the arrangement of a contact strip pair within the socket strip and the engagement $ offset in the body of the socket strip by 180 °, the disadvantage of the known prior art can advantageously be solved for the plug elements, in which only the one plug element is removed had to be used before plug elements of a different design could be used in its place.

Die erfindungsgemäße Steckdosenleiste kann von einem Paar gegenüberliegender Eingriffsvertiefungen als Leiste unendlich lang mit unendlich vielen gegenüberliegenden Paaren von Eingriffsvertiefungen gestaltet sein. In einem Beispielsfall liegen drei Eingriffsvertiefungen für Schutzkontakt-Stecker sechs Eingriffsvertiefungen für Europa-Flachstecker gegenüber. Das Schutzkontaktleisten-Paar im Inneren der erfindungsgemäßen Steckdosenleiste ist mit seinen Kontaktöffnungen an diese unterschiedliche Anzahl gegenüberliegender Eingriffsvertiefungen für die verschiedenartigen Steckerelemente angepaßt. So liegen den Durchgriffsöffnungen für die Stekkerstifte der einzelnen Steckerelemente gegenüber immer gerade die aufgekelchten Bereiche für den Eingriff der Steckerstifte in die Kontaktöffnungen der Kontaktleisten.The power strip according to the invention can be designed as a bar of infinitely long length with an infinite number of opposing pairs of engagement recesses from a pair of opposite engagement recesses. In one example case, three engagement recesses for protective contact plugs are opposite six engagement recesses for European flat plugs. The pair of protective contact strips in the interior of the power strip according to the invention is adapted with its contact openings to this different number of opposing engagement recesses for the different plug elements. Thus, the passage openings for the plug pins of the individual connector elements are always opposite the gated areas for the engagement of the connector pins in the contact openings of the contact strips.

An Steckerelementen ist in die erfindungsgemäße Steckdosenleiste bei entsprechender Anpassung jedes auf dem Markt befindliche Steckerelement einsetzbar. So entfällt beispielsweise in verschiedenen Ländern der beim Schutzkontakt-Stecker übliche, nach außen ragende Schutzkontakt.Any plug element on the market can be inserted into the socket strip according to the invention on plug elements with appropriate adaptation. In various countries, for example, the outward-reaching protective contact that is common for protective contact plugs is no longer required.

Dem gegenüber wird ein dritter Steckerstift mit einer im Inneren der Steckdosenleiste zusätzlich angeordneten Schutzkontaktschiene in Verbindung gebracht. Hier muß dann in den Boden der Vertiefung der erfindungsgemäßen Steckdosenleiste lediglich eine dritte öffnung für den Durchgriff des Schutzkontakt-Steckerstiftes eingebracht und innerhalb der Steckdosenleiste eine Kontaktleiste für die Erdung zusätzlich angeordnet werden. Je nach Einsatzland können hier runde, flache, rechteckige usw. Schutzkontakt-Steckerstifte zum Einsatz kommen. Die zusätzliche Öffnung in der Vertiefung der Steckdosenleiste kann an diese Figurationen angepaßt werden. Zusätzlich können bei allen Vertiefungen für die Steckerelemente die marktüblichen Kindersicherungen angebracht werden.In contrast, a third connector pin is connected to a protective contact rail additionally arranged in the interior of the power strip. Here then only a third opening for the penetration of the protective contact plug pin must be introduced into the bottom of the recess of the power strip according to the invention and a contact strip for grounding must additionally be arranged within the power strip. Depending on the country of use, round, flat, rectangular, etc. earthing contact plug pins can be used. The additional opening in the recess of the power strip can be adapted to these figurations. In addition, the usual child safety devices can be attached to all recesses for the connector elements.

Vorteilhaft ragen die Sperrzungen von der Basis der Steckdosenleiste auf, während die Kontaktleisten mit den Kontaktöffnungen von den Sperrzungen im Inneren der Steckdosenleiste klemmend gehaltert sind. Die Sperrzungen gemäß der Erfindung greifen zweckmäßigerweise an Außenbereichen jeweils benachbarter Kontaktöffnungen an. Außerdem besteht die Möglichkeit, daß die Sperrzungen jeweils von außen an den Verbindungsbereichen der Kontaktschienen zwischen zwei benachbarten Kontaktöffnungen angreifen. Die Kontaktschienen selbst können in den Verbindungsbereichen zwischen zwei benachbarten Kontaktöffnungen um 90° abgekröpft sein. Dadurch wird das Auffederungsbestreben der Kontaktschienen beim Einführen von Steckerstiften zum Nachteil benachbarter Kontaktöffnungen noch weiter reduziert.The locking tongues advantageously protrude from the base of the power strip, while the contact strips with the contact openings are held by the locking tongues in the interior of the power strip. The locking tongues according to the invention expediently attack on outer areas of adjacent contact openings. There is also the possibility that the locking tongues each engage from the outside on the connection areas of the contact rails between two adjacent contact openings. The contact rails themselves can be bent by 90 ° in the connection areas between two adjacent contact openings. This further reduces the tendency of the contact rails to spring open when inserting plug pins to the disadvantage of adjacent contact openings.

Mit der erfindungsgemäßen Steckdosenleiste wird durch die Verwendung nur eines einzigen Kontaktschienenpaares im Inneren dieser Leiste bei gleichzeitigen Eingriffsmöglichkeiten verschiedener Steckerelemente von zwei Seiten u.a. das Problem gelöst, daß eine Steckdosenleiste bekannter Dicke ohne weitere Verdickungen für den Einsatz unterschiedlicher Steckerelemente von zwei Seiten zur Verfügung steht. Ferner können die Vertiefungen der erfindungsgemäßen Steckdosenleiste durchgehend besetzt sein, ohne daß die Gefahr besteht, daß bei der Einführung eines Steckerelementes mit dickeren Steckerstiften benachbarte, um 180° versetzt eingesetzte Stekkerelemente mit beispielsweise dünneren Steckerstiften aus ihrer Klemmhalterung in den Kontaktöffnungen der Kontaktleisten durch Auffedern herausfallen.With the power strip according to the invention, the use of only a single pair of contact rails inside this bar with simultaneous intervention options of different connector elements from two sides solved, among other things, the problem that a socket strip of known thickness is available without further thickening for the use of different connector elements from two sides. Furthermore, the recesses of the power strip according to the invention can be occupied all the time without the risk that when a plug element with thicker plug pins is inserted, adjacent plug elements inserted with a 180 ° offset, for example with thinner plug pins, fall out of their clamp holder in the contact openings of the contact strips by springs.

Die in Fig. 1 gezeigte Steckdosenleiste 1 besteht aus den beiden Formteilen 11, 12. Die Formteile 11, 12 können beliebig in ihren Außenkonturen gestaltet sein. Die Formteile 11, 12 sind über Verschlußbügel 17 am Formteil 11 und Verschlußhaken 18 am Formteil 12 unlösbar miteinander verrastet. Dies bringt den Vorteil, daß die erfindungsgemäße Steckdosenleiste 1 ohne Zerstörung nicht mehr geöffnet werden kann.The socket strip 1 shown in Fig. 1 consists of the two molded parts 11, 12. The molded parts 11, 12 can be designed as desired in their outer contours. The molded parts 11, 12 are non-releasably locked together by means of a locking bracket 17 on the molded part 11 and a locking hook 18 on the molded part 12. This has the advantage that the power strip 1 according to the invention can no longer be opened without being destroyed.

Im Inneren der Steckdosenleiste 1 sind die Kontaktbügel 2, 3 mit ihren Kontaktöffnungen K 1, K 2 angeordnet. Die Kontaktöffnungen K 1 sind mit ihrer Aufkelchung K 11 zu den Durchgriffsöffnungen 131, 132 für die nicht gezeigten Steckerstifte der in der Vertiefung 13 eingesetzten Steckerelemente gerichtet. Die Kontaktöffnungen K 1 liegen an den Sperrzungen 5, 6 an, welche ein Auffedern beim Einsetzen der Steckerelemente in Richtung der Sperrzungen 5, 6 verhindern.In the interior of the power strip 1, the contact bracket 2, 3 are arranged with their contact openings K 1, K 2. The contact openings K 1 are directed with their convolutions K 11 to the through openings 131, 132 for the plug pins, not shown, of the plug elements used in the recess 13. The contact openings K 1 rest on the locking tongues 5, 6, which prevent springing open when the plug elements are inserted in the direction of the locking tongues 5, 6.

Die benachbarte Kontaktöffnung K 2 der Kontaktschienen 2, 3 ist mit ihrer Öffnung, d.h. mit dem aufgekelchten Bereich K 21 um 180° versetzt zur Aufkelchung K 11 der Kontaktöffnung K 1 gerichtet. Die Aufkelchung K 21 liegt gegenüber den Durchgriffsöffnungen 141, 142 der Eingriffsvertiefung 14 für das zugeordnete Steckerelement. Dieses nicht gezeigte Steckerelement ist ein Schutzkontakt-stecker, wobei der Schutzkontakt durch den Schlitz 19 in der Wand der Vertiefung 14 aus dem Inneren der Steckdosenleiste ragt. Die Vertiefung 14 trägt an ihrer Wand noch die Führung 16 für die Führungsfedern an dem Schutzkontaktstecker.The adjacent contact opening K 2 of the contact rails 2, 3 is with its opening, i.e. with the gated area K 21 offset by 180 ° to the cone K 11 of the contact opening K 1. The cone-out K 21 lies opposite the through openings 141, 142 of the engagement recess 14 for the associated plug element.
