Description

Die Erfindung betrifft einen Positionsschalter nach dem Oberbegriff von Anspruch 1.The invention relates to a position switch according to the preamble of claim 1.

Aus der Druckschrift DE 39 43 377 C1 ist ein Positionsschalter bekannt, der aus einem Gehäuse und einem mit diesem verbundenen Antriebskopf besteht. Das Gehäuse weist eine gegenüber dem Antriebskopf befindliche Einführöffnung für anzuschließende Anschlussleitungen sowie eine durch einen Deckel verschließbare, seitliche Montageöffnung auf. Vom Antriebskopf führt ein Betätigungsstößel in den Innenraum des Gehäuses. Im Gehäuse ist ein Kontaktträger gelagert, der durch den Betätigungsstößel in der durch diesen vorgegebenen Betätigungsrichtung verschoben wird. Der Kontaktträger trägt zwei Kontaktbrücken, die in Betätigungsrichtung hintereinander angeordnet sind. Jeder Kontaktbrücke sind zwei Festkontakte zugeordnet, die mit Schraubanschlüssen verbunden und im Innenraum paarweise an gegenüberliegenden, an die Montageöffnung sich anschließenden Seitenwänden gehalten sind. Vor dem Kontaktträger und den Schraubanschlüssen ist eine Schutzkappe gesetzt. Ein Nachteil dieses Positionsschalters besteht darin, dass sich das Anklemmen der Anschlussleitungen in dem klein bemessenen verbleibenden Innenraum schwierig gestaltet. Von weiterem Nachteil ist, dass beim Anklemmen der Anschlussleitungen die Leiterenden bei einem Kontaktpaar entgegen der Einführrichtung abzubiegen sind. Diese Nachteile sind besonders schwerwiegend bei Verwendung von Anschlussleitungen mit größeren Leitungsquerschnitten.From the document DE 39 43 377 C1, a position switch is known which consists of a Housing and connected to this drive head consists. The housing has an opposite of the drive head insertion opening for to be connected Connecting cables as well as a lid which can be closed by a lid Mounting opening on. From the drive head leads an actuating plunger into the interior of the housing. In the housing, a contact carrier is supported by the actuating plunger is shifted in the predetermined direction of actuation by this. The contact carrier carries two contact bridges, one behind the other in the direction of actuation are arranged. Each contact bridge is assigned two fixed contacts, which with Screw terminals connected and in the interior in pairs on opposite, are held on the mounting opening adjoining side walls. In front the contact carrier and the screw terminals a protective cap is set. One Disadvantage of this position switch is that the clamping of the connecting cables designed in the small-sized remaining interior difficult. Another disadvantage is that when connecting the connecting cables the Conductor ends are bent in a contact pair opposite to the insertion direction. These disadvantages are particularly serious when using connecting cables with larger cable cross-sections.

Durch die Montageöffnung 24 betrachtet befinden sich die Anschlussblöcke 54, 56 und die in diesen gelagerten Anschlussklemmen 70 in einer Reihe nebeneinander und senkrecht zur Betätigungsrichtung R. Durch diese Anordnung der Anschlussklemmen 70 sind diese zum Anklemmen der durch die Einführöffnung 22 eingeführten Anschlussleitungen leicht zugängig, wobei bereits angeklemmte Anschlussleitungen das Anklemmen der übrigen bzw. zusätzlicher Anschlussleitungen nicht behindern können.Viewed through the mounting opening 24 are the terminal blocks 54, 56th and the terminals 70 mounted in these are juxtaposed in a row and perpendicular to the direction of actuation R. By this arrangement of the terminals 70, these are for clamping the inserted through the insertion opening 22 Connecting cables easily accessible, with already attached connecting cables Do not obstruct the connection of the remaining or additional connecting cables can.

Die Anschlussblöcke 54 und 56 sind nach Fig. 1 jeweils mit einer zur Montageöffnung 24 zeigenden ersten Vorderfront 76 ausgestattet, die gegenüber der durch die Montageöffnung 24 gebildeten Ebene schräg verläuft. Die erste Vorderfront 76 verläuft in Betätigungsrichtung R mit zunehmendem Abstand von der Montageöffnung 24. Die ersten Vorderfronten 76 der Anschlussblöcke 54, 56 verlaufen in einer Ebene. Im eingebauten Zustand grenzt an die ersten Vorderfronten 76 der Anschlussblöcke 54 und 56 stufenlos eine zweite Vorderfront 78, welche das Innengehäuse 62 in Richtung zur Montageöffnung 24 begrenzt. Die zweite Vorderfront 78 ist konkav ausgebildet und verläuft in Betätigungsrichtung R mit zunehmendem Abstand zur Montageöffnung 24. Durch diese Ausbildung der Vorderfronten 76, 78 wird zweierlei bewirkt: Zum einen treten den Leiterenden beim Einführen der Anschlussleitungen durch die Einführöffnung 22 keine hemmenden Flächen oder Abstufungen entgegen. Statt dessen gleiten die Leiterenden über die erfindungsgemäß geformten Vorderfronten 78 und 76 und werden dabei leicht zur Montageöffnung 24 hin gebogen. Dadurch lassen sich die Leiterenden problemlos in die Anschlussklemmen 70 einführen. Zum anderen ist durch die beschriebene Ausbildung der Vorderfronten 76, 78 zwischen der Einführöffnung 22 und den Anschlussklemmen 70 ein großer Raum geschaffen worden. Dieser Raum erleichtert einerseits das Anklemmen der Anschlussleitungen und dient anderseits als Stauraum für die problemlose Unterbringung überschüssiger Leitungslängen.The terminal blocks 54 and 56 are shown in FIG. 1 each with a mounting hole 24 facing first front end 76 equipped opposite the through the mounting hole 24 formed plane obliquely. The first front panel 76 runs in Actuation direction R with increasing distance from the mounting hole 24. Die first front fronts 76 of the terminal blocks 54, 56 extend in a plane. Im installed Condition adjacent to the first front panels 76 of the terminal blocks 54 and 56 steplessly a second front panel 78, which the inner housing 62 in the direction of Mounting opening 24 limited. The second front panel 78 is concave and runs in the direction of actuation R with increasing distance to the mounting opening 24th This design of the front fronts 76, 78 has two effects: First enter the conductor ends during insertion of the connecting cables through the insertion opening 22 no inhibitory surfaces or gradations contrary. Instead, glide the conductor ends on the invention shaped front fronts 78 and 76 and be easily bent to the mounting hole 24 out. This can be the Insert conductor ends easily into the terminals 70. The other is by the described design of the front fronts 76, 78 between the insertion opening 22 and the terminals 70 a large space has been created. This On the one hand, space makes it easier to connect the connecting cables and on the other hand as storage space for the problem-free accommodation of excess line lengths.
