Abstract

The terminal (1) has a pressure piece (2) movably mounted between guiding units (21, 22) that are arranged along legs (11, 12). An end (3a) of an elastic element (3) e.g. parallel-guided springs (61, 62), is arranged on a base part (13) and another end (3b) is arranged on the pressure piece such that a compressive force is directed in a direction of an open end (14) of a U-shaped yoke (10) opposite to the base part. Two wings (31, 32) are arranged on the pressure piece, where the wings generate a digitally induced counterforce against the compressive force and compress the elastic element. The pressure piece comprises a sheet metal part having T-pieces, where the T-pieces and wings are designed as a coherent sheet metal part.

Description

Die Erfindung betrifft eine Schirmanschlussklemme mit einem einen ersten Schenkel, einen zweiten Schenkel und ein Basisteil aufweisenden U-förmigen Bügel, wobei ein elastisches Element derart zwischen dem ersten Schenkel und dem zweiten Schenkel angeordnet ist, dass auf ein Druckstück eine Druckkraft ausgeübt wird.The invention relates to a shield terminal with a first leg, a second leg and a base part having U-shaped bracket, wherein an elastic member is arranged between the first leg and the second leg, that a pressure force is exerted on a pressure piece.

Unter einer Schirmanschlussklemme im Sinne der Erfindung ist eine Klemmvorrichtung zu verstehen, mit welcher es möglich ist einen Kabelschirm von einem Kabel mit Signalleitungen an eine Schirmschiene zu klemmen und so einen möglichst impedanzarmen und niederohmigen Kontaktübergang von Schirmgeflecht über die Schirmanschlussklemme zu einer Schirmschiene zu ermöglichen.Under a Schirmanschlussklemme in the context of the invention is a clamping device to understand, with which it is possible to clamp a cable shield of a cable with signal lines to a shield rail and thus to enable a low-impedance and low impedance contact transition of shielding braid on the shield terminal to a shield rail.

Eine derartige Schirmanschlussklemme ist aus der europäischen Patentschrift EP 0 334 975 B1 bekannt. Bei der bekannten Schirmanschlussklemme ist es jedoch von Nachteil, dass für die Verbindung der Schirmklemme und der Schirmschiene ein aufwendiger Montageaufwand nötig ist.Such a shield terminal is known from the European patent EP 0 334 975 B1 known. In the known shield terminal, however, it is disadvantageous that a complex installation effort is required for the connection of the shield terminal and the shield rail.

Aus dem Gebrauchsmuster DE 298 95 977 U1 ist ein Anschlußelement für elektrische Leiter bekannt, das ein im wesentlichen L-förmig ausgebildet Druckstück 11 aufweist. Das Druckstück ist in einer Offenstellung des Anschlußelementes in einer Kipphalterung 17-18 lösbar arretiert. Zur Lösung der Arretierung der Kipphalterung gelangen die seitlich umgreifenden Führungs- und Haltelaschen 17 in einer Kippbewegung von den einspringenden Schultern 18 herunter, wodurch die Druckfeder 7 automatisch das Druckstück 11 nach unten preßt.From the utility model DE 298 95 977 U1 a connecting element for electrical conductors is known, which has a substantially L-shaped pressure piece 11. The pressure piece is releasably locked in an open position of the connecting element in a tilting bracket 17-18. To solve the locking of the tilting holder reach the laterally encompassing guide and retaining tabs 17 in a tilting movement of the re-entrant shoulders 18 down, whereby the compression spring 7 automatically presses the pressure piece 11 down.

Es ist daher die Aufgabe der vorliegenden Erfindung eine Schirmanschlussklemme bereitzustellen, bei welcher eine Montage eines Kabels mit einem Abschirmgeflecht an eine Schirmschiene erleichtert wird.It is therefore an object of the present invention to provide a shield terminal in which a mounting of a cable with a Abschirmgeflecht is facilitated to a shield rail.

Die Aufgabe wird für die eingangs genannten Schirmanschlussklemme dadurch gelöst, dass der erste Schenkel ein längs des ersten Schenkels angeordnetes erstes Führungsmittel und der zweite Schenkel ein längs des zweiten Schenkels angeordnetes zweites Führungsmittel aufweist, wobei das Druckstück zwischen dem ersten und zweiten Führungsmittel bewegbar gelagert ist, mit einem am Druckstück angeordneten ersten Flügel und zweiten Flügel, wobei die Flügel ausgestaltet sind um mit den Fingern einer menschlichen Hand eine Gegenkraft entgegen der Druckkraft zu erzeugen und damit das elastische Element zusammen zu drücken. Als Kraft ist hier eine vektorielle Größe mit Richtung und Betrag zu verstehen, wenn hier im Sinne der Erfindung von einer Richtung im Bezug auf die Kraft gesprochen wird, so ist dies bezogen auf die Richtungskomponente der angesprochenen Kraft unter der Berücksichtigung das Kräfte eine vektorielle Größe sind.The object is achieved for the above-mentioned shield connection terminal in that the first leg has a first guide means arranged along the first leg and the second leg has a second guide means arranged along the second leg, wherein the pressure piece is movably mounted between the first and second guide means, with a first wing and second wing arranged on the pressure piece, wherein the wings are designed to generate with the fingers of a human hand a counterforce against the pressure force and thus to press the elastic element together. As a force is here to understand a vectorial magnitude with direction and magnitude, if it is spoken in the sense of the invention of a direction in relation to the force, so this is based on the directional component of the mentioned force, taking into account the forces are a vectorial size ,

Bei dieser Art von Schirmanschlussklemmen ist es von Vorteil, dass sich in dem U-förmigen Bügel ein gleitend gelagertes Druckstück befindet, dass durch ein elastisches Element mit beispielsweise einer Feder mit einer konstanten Kraft nach unten gedrückt wird, wobei es durch die U-förmige Ausgestaltung des Bügels möglich ist in den durch das U gebildeten Raum ein oder mehrere Kabel einzulegen, wobei bei den Kabeln das Schirmgeflecht bereits offen liegt. Das elastische Element sorgt nun dafür, dass über das Druckstück das Kabel mit seinem Schirmgeflecht in Richtung des offenen Endes gedrückt wird, wobei bei Anklemmen an einer Schirmschiene diese an dem offenen Ende angeordnet ist.In this type of shielding terminals, it is advantageous that in the U-shaped bracket is a slidingly mounted pressure piece that is pressed by an elastic member with, for example, a spring with a constant force down, it by the U-shaped configuration the bracket is possible to insert one or more cables in the space formed by the U, wherein in the cables, the braid is already open. The elastic element now ensures that the cable is pressed with its braided shield in the direction of the open end via the pressure piece, wherein when clamped to a shield rail, this is arranged at the open end.

Im Gegensatz zu den aus dem Stand der Technik bekannten Schirmanschlussklemmen ist es bei dieser Schirmanschlussklemme durch den ersten Flügel und den zweiten Flügel, welche man auch als zwei Griffe bezeichnen könnte, möglich mit einer Einhandbedienung auf das elastische Element eine Gegenkraft zu erzeugen, so dass die eingelegten Kabel in den durch das U gebildeten Raum Platz finden und gleichzeitig die Schirmanschlussklemme montiert werden kann und nach Loslassen des ersten und zweiten Flügels die Druckkraft derart auf das Druckstück wirkt, dass die Kabel eingeklemmt werden. Vorteilhafter Weise sind die Flügel in einer durch den U-förmigen Bügel gebildeten Durchtrittsöffnung angeordnet.In contrast to the shield terminals known from the prior art, it is possible in this shield connection terminal by the first wing and the second wing, which could also be referred to as two handles, with a one-handed operation on the elastic element to generate a counterforce, so that the inserted cable in the space formed by the U space and at the same time the shield terminal can be mounted and after releasing the first and second wing, the pressure force acts on the pressure piece so that the cables are clamped. Advantageously, the wings are arranged in a passage formed by the U-shaped bracket.

Für eine leichte Montage an einer Schirmschiene ist es vorteilhaft, wenn an den Schenkeln an dem den Basisteil gegenüber liegenden offenen Ende des Bügels je ein Arm rechtwinklig zur Druckkraft angeordnet ist und der Arm derart ausgestaltet ist, dass sich zwischen dem offenen Ende des Bügels und einer Längsseite des Arms ein Zwischenraum zur Aufnahme einer Schirmschiene bildet. Durch das Zurückziehen des elastischen Elementes mit einer menschlichen Hand, wobei dies durch eine 3-Finger-Bedienung geschehen kann, wobei der Daumen auf das Basisteil drückt, der Zeigefinger sich einen Flügel greift und der Mittelfinger sich einen anderen Flügel greift, wird der Zwischenraum gebildet und kann so durch Aufschieben der Schirmanschlussklemme auf eine Schirmschiene die Schirmschiene aufnehmen.For easy mounting to a shield rail, it is advantageous if each arm is arranged at right angles to the pressure force on the legs at the base part opposite the open end of the bracket and the arm is designed such that between the open end of the bracket and a Longitudinal side of the arm forms a space for receiving a shield rail. By retracting the elastic member with a human hand, which can be done by a 3-finger operation, with the thumb presses on the base member, the index finger engages a wing and the middle finger engages another wing, the gap is formed and can thus absorb the shield rail by sliding the shield connection terminal onto a shield rail.

Um ein Verrutschen des Armes an der Schirmschiene zu verhindern, ist an dem Ende des Arms ein Widerlager angeordnet.In order to prevent slippage of the arm on the shield rail, an abutment is arranged at the end of the arm.

In einer vorteilhaften Ausgestaltung wird für das elastische Element eine Ausführung mit zwei parallel geführten Federn verwendet.In an advantageous embodiment, an embodiment with two parallel springs is used for the elastic element.

Eine weitere bevorzugte Ausgestaltungsvariante sieht vor, dass das Druckstück als ein Blechteil mit T-Stücken ausgestaltet ist und die T-Stücke in denen als Längsschlitzen ausgestalteten Führungsmittel geführt werden.A further preferred embodiment variant provides that the pressure piece is designed as a sheet metal part with T-pieces and the T-pieces are guided in which designed as a longitudinal slots guide means.

Für eine Fertigung einer derartigen Schirmanschlussklemme ist es von Vorteil wenn das Druckstück, die Flügel und die T-Stücke als ein zusammenhängendes Blechteil ausgestaltet sind.For a production of such a shield terminal, it is advantageous if the pressure piece, the wings and the T-pieces are designed as a continuous sheet metal part.

FIG. 2
from FIG. 1 known shielding terminal with a shielding rail shown.

Gemäß der FIG 1 weist eine Schirmanschlussklemme 1 einen U-förmigen Bügel 10 mit einem ersten Schenkel 11, einem zweiten Schenkel 12 und einen Basisteil 13 auf. Ein elastisches Element 3, insbesondere eine erste Feder 61 und eine zweite Feder 62, sorgen für das Erzeugen einer Druckkraft F. Das elastische Element 3 ist derart zwischen dem ersten Schenkel 11 und dem zweiten Schenkel 12 angeordnet, dass die Druckkraft F auf ein Druckstück 2 ausgeübt wird. Der erste Schenkel 11 weist ein längs des ersten Schenkels 11 angeordnetes erstes Führungsmittel 21 auf, und der zweite Schenkel 12 weist ein längs des zweiten Schenkels 12 angeordnetes zweites Führungsmittel 22 auf, wobei die Führungsmittel 21,22 als Längsschlitze in den Schenkeln 11,12 angeordnet sind. In diesen Längsschlitzen kann das Druckstück 2 mit einem am Druckstück 2 angeordnetem ersten T-Stück 71 und zweiten T-Stück 72 gleitend gelagert werden und ist somit gegen ein Verrutschen gesichert. Ein erstes Ende 3a des elastischen Elementes 3 ist an einer Innenseite des Basisteils 13 angeordnet und ein zweites Ende 3b des elastischen Elementes ist an einer Innenseite des Druckstücks 2 angeordnet, wobei diese Anordnung ermöglicht, dass die Druckkraft F in Richtung eines dem Basisteil 13 gegenüber liegenden offenen Ende des Bügels 10 gerichtet ist.According to the FIG. 1 For example, a shield connection terminal 1 has a U-shaped bracket 10 with a first leg 11, a second leg 12 and a base part 13. An elastic element 3, in particular a first spring 61 and a second spring 62, provide for the generation of a compressive force F. The elastic element 3 is arranged between the first leg 11 and the second leg 12 in such a way that the pressure force F acts on a pressure piece 2 is exercised. The first leg 11 has a first guide means 21 arranged along the first leg 11, and the second leg 12 has a second guide means 22 arranged along the second leg 12, wherein the guide means 21, 22 are arranged as longitudinal slots in the legs 11, 12 are. In these longitudinal slots, the pressure piece 2 with a pressure piece 2 arranged on the first tee 71 and second tee 72 are slidably mounted and is thus secured against slipping. A first end 3a of the elastic member 3 is disposed on an inner side of the base member 13, and a second end 3b of the elastic member is disposed on an inner side of the pressure member 2, this arrangement allowing the pressing force F to be toward a base member 13 open end of the bracket 10 is directed.

Der erste Flügel 31 und der zweite Flügel 32 sind in einer durch den U-förmigen Bügel 10 gebildeten Durchtrittsöffnung 30 angeordnet.The first wing 31 and the second wing 32 are arranged in a passage opening 30 formed by the U-shaped bracket 10.

Um das Aufschieben, Stecken oder Klemmen auf eine Schirmschiene 51 zu erleichtern, ist an den dem Basisteil 13 gegenüberliegenden offenen Ende 14 des Bügels 10 ein erster Arm 41 und ein zweiter Arm 42 rechtwinklig zur Druckkraft F angeordnet. Dabei ist der erste Arm 41 sowie der zweite Arm 42 derart ausgestaltet, dass sich zwischen dem offenen Ende 14 des Bügels 10 und einer ersten Längsseite 41a des ersten Arms 41 und einer zweiten Längsseite 42a des Arms 42 ein Zwischenraum 50 zur Aufnahme einer Schirmschiene 51 bildet.In order to facilitate the pushing, plugging or clamping on a shield rail 51, a first arm 41 and a second arm 42 is arranged at right angles to the pressing force F at the base part 13 opposite the open end 14 of the bracket 10. In this case, the first arm 41 and the second arm 42 are configured such that between the open end 14 of the bracket 10 and a first longitudinal side 41a of the first arm 41 and a second longitudinal side 42a of the arm 42 forms a gap 50 for receiving a shield rail 51 ,

Um das Erzeugen einer Gegenkraft G zu symbolisieren, stelle man sich eine Einhandbedienung der Schirmanschlussklemme 1 mit einer Hand vor. Dabei drückt der Daumen von oben auf die Schirmanschlussklemme 1, so dass der Daumen auf dem Basisteil 13 liegt und der Zeigefinger greift unter den ersten Flügel 31 und der Mittelfinger der menschlichen Hand greift dabei unter den zweiten Flügel 32 und durch Druck auf den Daumen bzw. durch Zug der beiden Finger wird das elastische Element 3 durch die Gegenkraft G entgegen seiner Druckkraft F bewegt und der Zwischenraum 50 kann somit frei gemacht werden.To symbolize the generation of a counter force G, imagine a one-handed operation of the shield connection terminal 1 with one hand. The thumb presses from above on the shield terminal 1, so that the thumb lies on the base part 13 and the index finger engages under the first wing 31 and the middle finger of the human hand engages under the second wing 32 and by pressing the thumb or by pulling the two fingers, the elastic element 3 is moved by the counter force G against its compressive force F and the gap 50 can thus be made free.

Gemäß der FIG 2 ist eine auf eine Schirmschiene 51 montierte Schirmanschlussklemme 1 dargestellt. Sämtliche Einzelteile und Merkmale der Schirmanschlussklemme 1 entsprechen der Schirmanschlussklemme 1 aus der FIG 1, lediglich in der perspektivischen Darstellung ist die Schirmanschlussklemme 1 um 90° gedreht. In der Darstellung gemäß FIG 2 befinden sich noch keine in die Schirmanschlussklemme 1 geführten Kabel, aber wenn die Gegenkraft G über den ersten Flügel 31 und den zweiten Flügel 32 mit Druck auf das Basisteil 13 erzeugt wird, verschiebt sich das Druckstück 2 nach oben und zwischen dem Druckstück 2 und der Schirmschiene 51 können Kabel mit ihrem Schirmgeflecht eingefügt werden und durch Loslassen des ersten Flügels 31 und des zweiten Flügels 32 lässt die Druckkraft F das Druckstück 2 auf das Schirmgeflecht der Kabel drücken, welche somit sicher eingeklemmt sind.According to the FIG. 2 a shield terminal 1 mounted on a shield rail 51 is shown. All items and features of the shield terminal 1 correspond to the shield terminal 1 of the FIG. 1 , only in the perspective view, the shield terminal 1 is rotated by 90 °. In the illustration according to FIG. 2 There are still no guided in the shield terminal 1 cable, but when the counterforce G is generated via the first wing 31 and the second wing 32 with pressure on the base member 13, the pressure piece 2 shifts upward and between the pressure piece 2 and the shield rail 51 cables can be inserted with their braid and by releasing the first wing 31 and the second wing 32 can the compressive force F push the pressure piece 2 on the screen braid of the cables, which are thus securely clamped.
