Definitions
- the invention relates to a circuit breaker with a terminal comprising a clamping frame which is displaceable by turning a screw in a displacement direction, wherein the clamping frame comprises at least one side wall whose outer surface lies in a plane, and which defines a defined perpendicular to the direction of width an inner surface of a portion of a housing part of the circuit breaker has.
- FIG. 1 an interior perspective view of a circuit breaker according to the prior art
- FIG. 2 the view of the opened circuit breaker according to FIG. 1 from the side
- FIG. 3 the section III-III FIG. 2 with closed circuit breaker.
- a generally designated 10 circuit breaker comprises a first housing part 12 which in the 1 and 2 is shown open and in the representation according to FIG. 3 by a second housing part 14, which serves as a lid, is closed.
- a plurality of terminals is formed in circuit breakers.
- One of these terminals, namely a designated 16 in total terminal is in the 1 to 3 shown.
- the clamp 16 comprises a clamping frame 18, in which a screw 20 engages.
- the clamping frame 18 has an upper wall 22 with an opening for the screw 20, a lower wall 24 which includes a bent portion 25, and the upper wall 22 and the lower wall 24 are interconnected by side walls 26 and 28.
- the side walls 26 and 28 have plate-shaped sections. This means that in particular their outer surface is flat, ie lies in one plane.
- a terminal 30 protrudes.
- the clamp is used to press an electrical conductor, not shown in the FIG against the terminal 30.
- An electrical conductor is in particular via an in FIG. 1 half-visible opening 32 in the clamping frame 18 inserted, namely between the side walls 26 and 28 and between the lower wall 24 and the terminal 30.
- the screw 20 is supported on the terminal 30 from (not shown). When turning the screw 20, therefore, the clamping frame 18 moves relative to the unmoved screw in a direction of displacement, namely upwards. In this displacement of the clamping frame 18 thus reduces the distance between the bottom wall 24 and the terminal 30.
- a through the opening 32 between the side walls 28 and 26 of the clamping frame 18 inserted electrical conductor is finally clamped between the wall 24 and the terminal 30 and thereby firmly pressed against the terminal 30 so that the desired electrical contact is made. Due to the resulting resistance when clamping the electrical conductor further movement of the clamping frame 18 is prevented in the direction of displacement. Instead, it comes with a further rotation of the screw 20 to a rotation of the clamping frame until it rests against the terminal 30, which can prevent further rotation as a metal part.
- the clamping frame is in the twisted position in FIG. 3
- the side walls 26 and 28 are slightly tilted relative to the terminal 30. The problem here is that the side walls 26 and 28 press against the housing parts 12 and 14.
- respective portions 34 of the housing part 12 and 36 of the housing part 14, to which the side walls 28 and 26 point, are also designed to have a flat inner surface.
- the inner surface of the housing part 12 in the region of the portion 34 lies in the in FIG. 3 indicated plane E (which is perpendicular to the plane of the paper), and the inner surface of the portion 36 of the housing part 14 is located in the plane perpendicular to the plane extending plane E '.
- plane E which is perpendicular to the plane of the paper
- the inner surface of the portion 36 of the housing part 14 is located in the plane perpendicular to the plane extending plane E '.
- the inner surface of the portion of the housing part opposite a side wall of the clamping frame (seen over the same width as the side wall) is not completely in a single plane.
- the portion of the housing part is reshaped and that it should be reshaped so that upon rotation of the clamping frame, the side wall does not touch the housing part.
- a first width portion of the inner surface of the portion of the housing part to which the side wall faces, in a first plane, and a second width portion of the inner surface of the portion of the housing part lies in a second plane (in a plane of rotation perpendicular to the direction of displacement ) is tilted by a predetermined angle to the first plane.
- the predetermined angle can be between 2 ° and 10 °. Since the direction of rotation of the screw dictates how around the side walls 26 and 28 tilt, where a contact of the side walls would take place with the housing parts in a twisting, a part of the housing part may be removed, whereby the side walls then turn into space and especially do not press against the housing parts.
- a recess in the housing part is formed in a section of the portion of the housing part to which the side wall faces.
- the recess may be formed where otherwise the contact with the housing part would take place and on the other hand does not have to be formed there where no contact with the side wall with the housing part would occur anyway.
- the recess can basically be shaped as desired. For example, but it has an inner surface which lies in a plane which is parallel to a plane in which the remaining width portion of the housing part, to which the side wall faces.
- the inner surface of the recess is nothing more than the inner surface of the portion of the housing part displaced by a predetermined distance, this offset being limited by a predetermined distance to the area of a recess and not to the entire portion of the housing part (ie a wall of the housing part as a whole) must be extended.
- the predetermined distance may be between 0.1 mm and 0.5 mm.
- FIG. 4 generally designated 40 circuit breaker has substantially the same features as the circuit breaker 10 FIG. 1 on.
- the circuit breaker 40 is different from the circuit breaker 10 FIG. 1 by the configuration of the inner surface of the portions 34 and 36 of the housing parts 12 and 14:
- the portions 34 and 36 are those portions of the housing parts 12 and 14, to which the side walls 28 and 26 respectively. While according to FIG. 3 the inner surface of these portions 34 and 36 are each in a plane E and E ', this is no longer the case in the embodiment according to the invention. Rather, a width portion 42 of the portion 34 is to be distinguished from a width portion 44.
- the inner surface of the width portion 42 lies in a plane E1 (which is perpendicular to the paper plane of FIG.
- the inner surface of the width portion 44 lies in a plane perpendicular to the paper plane of FIG. 6 extending plane E2, which is rotated with respect to the plane E1 by an angle ⁇ of about 3 ° to 5 °.
- a kink 46 Between the width sections 42 and 44 is to a certain extent a kink 46.
- the presence of this kink 46 distinguishes the embodiments according to the 1 to 3 of the embodiments according to the FIGS. 4 to 6 , The course of the kink 46 is in particular in FIG. 5 clearly visible.
- a kink 48 corresponding kink 46 is also available at the inner surface of the portion 36 of the housing part 14, to which the side wall 26 points.
- This kink 48 separates a width portion 50 of the portion whose inner surface lies in a plane E1 'of a width portion 54, the inner surface lies in a plane E2'.
- the planes E1 and E1 'on the one hand and the planes E2 and E2' on the other hand are parallel to each other, so that the planes E1 'and E2' are also rotated by an angle ⁇ .
- this condition is not necessary for the operation of the invention. Rather, it is important that, unlike in the prior art according to FIG.
- a simple recess 54 in the housing part 12 and a recess 56 in the housing part 14 may be sufficient to prevent the side walls 28 and 26 housing parts 12 , thereby touch.
- the recesses 54 and 56 may be designed so that in the region of the recess, the housing part 12 has an inner surface which lies in a plane E4, which is parallel to a plane E3, in which the remaining portion of the housing part 12, to which the side wall 28 points lies.
- sections of the housing part 14 which lie in a plane E3 '(outside the recess 56, but opposite the side wall 26) or E4' (in the region of the recess 56).
- the housing parts 12 and 14 By a specific shape of the housing parts 12 and 14 is ensured according to the invention that only in the places material is eliminated, where it is necessary for a rotation of the side walls 26 and 28, if they are not to exert forces on the housing parts 12 and 14. In the remaining area the housing parts 12 and 14, ie in particular in the remaining region of the sections 34 and 36, to which the side walls 28 and 26, the wall thickness of the housing parts 12 and 14 remain thicker. This ensures sufficient stability. The housing parts 12 and 14 are thus weakened only in a small area, and their manufacturability and functionality is not affected. Rather, the problem of the exertion of forces by the side walls 26 and 28 is eliminated.

Abstract
Description
Die Erfindung betrifft einen Leitungsschutzschalter mit einer Klemme, die einen Klemmrahmen umfasst, der durch Drehen einer Schraube in eine Verschieberichtung verschiebbar ist, wobei der Klemmrahmen zumindest eine Seitenwand umfasst, deren Außenoberfläche in einer Ebene liegt, und die über eine senkrecht zur Verschieberichtung definierte Breite zu einer Innenoberfläche eines Abschnitts eines Gehäuseteils des Leitungsschutzschalters weist.The invention relates to a circuit breaker with a terminal comprising a clamping frame which is displaceable by turning a screw in a displacement direction, wherein the clamping frame comprises at least one side wall whose outer surface lies in a plane, and which defines a defined perpendicular to the direction of width an inner surface of a portion of a housing part of the circuit breaker has.
Ein solcher Leitungsschutzschalter ist allgemein bekannt und in den
Ein im Ganzen mit 10 bezeichneter Leitungsschutzschalter gemäß dem Stand der Technik umfasst ein erstes Gehäuseteil 12, das in den
In den Klemmrahmen 18 ragt ein Anschluss 30 hinein. Die Klemme dient dazu, einen in den FIG nicht gezeigten elektrischen Leiter gegen den Anschluss 30 zu drücken. Ein elektrischer Leiter ist insbesondere über eine in
Somit nimmt man bisher in Kauf, dass die Seitenwände 26 und 28 beim Drehen des Klemmrahmens 18 die Gehäuseteile 14 bzw. 12 berühren. Bei diesem Berühren wird eine Kraft auf die Gehäuseteile 12 und 14 ausgeübt, welche in
Es ist Aufgabe der Erfindung, einen Leitungsschutzschalter der eingangs genannten Art dahingehend weiterzubilden, dass ein Auseinanderklaffen verhindert wird, insbesondere dass beim Festklemmen eines elektrischen Leiters in dem Klemmrahmen an dem Anschluss keine Kräfte auf Gehäuseteile ausgeübt werden.It is an object of the invention to develop a circuit breaker of the type mentioned in that a gaping apart is prevented, in particular that when clamping an electrical conductor in the clamping frame at the port no forces are exerted on housing parts.
Die Aufgabe wird durch einen Leitungsschutzschalter mit den Merkmalen gemäß Patentanspruch 1 gelöst.The object is achieved by a circuit breaker with the features of claim 1.
Erfindungsgemäß liegt die Innenoberfläche des einer Seitenwand des Klemmrahmens gegenüberliegenden Abschnitts des Gehäuseteils (gesehen über dieselbe Breite wie die Seitenwand) nicht vollständig in einer einzigen Ebene.According to the invention, the inner surface of the portion of the housing part opposite a side wall of the clamping frame (seen over the same width as the side wall) is not completely in a single plane.
Anstatt also gemäß ursprünglichen Konzepten einfach den Abstand zwischen Seitenwand und gegenüberliegendem Abschnitt des Gehäuseteils zu vergrößern, wird der Abschnitt des Gehäuseteils umgeformt und zwar soll er genau so umgeformt sein, dass bei einem Verdrehen des Klemmrahmens die Seitenwand das Gehäuseteil nicht berührt.So instead of simply enlarging the distance between the side wall and opposite portion of the housing part according to the original concepts, the portion of the housing part is reshaped and that it should be reshaped so that upon rotation of the clamping frame, the side wall does not touch the housing part.
Bei einer ersten Ausführungsform liegt ein erster Breitenabschnitt der Innenoberfläche des Abschnitts des Gehäuseteils, zu dem die Seitenwand weist, in einer ersten Ebene, und ein zweiter Breitenabschnitt der Innenoberfläche des Abschnitts des Gehäuseteils liegt in einer zweiten Ebene, die (in einer Drehebene senkrecht zur Verschieberichtung) um einen vorbestimmten Winkel zur ersten Ebene verkippt ist.In a first embodiment, a first width portion of the inner surface of the portion of the housing part to which the side wall faces, in a first plane, and a second width portion of the inner surface of the portion of the housing part lies in a second plane (in a plane of rotation perpendicular to the direction of displacement ) is tilted by a predetermined angle to the first plane.
Der vorbestimmte Winkel kann zwischen 2° und 10° liegen. Da die Drehrichtung der Schraube vorgibt, wie herum sich die Seitenwände 26 und 28 verkippen, kann dort, wo eine Berührung der Seitenwände mit den Gehäuseteilen bei einem Verdrehen stattfinden würde, ein Teil des Gehäuseteils weggenommen sein, wodurch sich die Seitenwände dann ins Leere hineinverdrehen und insbesondere nicht gegen die Gehäuseteile drücken.The predetermined angle can be between 2 ° and 10 °. Since the direction of rotation of the screw dictates how around the
Bei einer alternativen Ausführungsform ist in einem Teilabschnitt des Abschnitts des Gehäuseteils, zu dem die Seitenwand weist, eine Aussparung in dem Gehäuseteil ausgebildet.In an alternative embodiment, a recess in the housing part is formed in a section of the portion of the housing part to which the side wall faces.
Die Aussparung kann dort gebildet sein, wo sonst die Berührung mit dem Gehäuseteil stattfinden würde und muss andererseits dort nicht ausgebildet sein, wo ohnehin keine Berührung mit der Seitenwand mit dem Gehäuseteil auftreten würde.The recess may be formed where otherwise the contact with the housing part would take place and on the other hand does not have to be formed there where no contact with the side wall with the housing part would occur anyway.
Die Aussparung kann grundsätzlich beliebig geformt sein. Zum Beispiel aber hat sie eine Innenoberfläche, die in einer Ebene liegt, welche zu einer Ebene parallel ist, in der der restliche Breitenabschnitt des Gehäuseteils liegt, zu dem die Seitenwand weist. In diesem Falle ist die Innenoberfläche der Aussparung nichts anderes als die um einen vorbestimmten Abstand versetzte Innenoberfläche des Abschnitts des Gehäuseteils, wobei diese Versetzung um einen vorbestimmten Abstand eben auf den Bereich einer Aussparung beschränkt ist und nicht auf den gesamten Abschnitt des Gehäuseteils (also eine Wand des Gehäuseteils als Ganzes) ausgedehnt sein muss. Der vorbestimmte Abstand kann zwischen 0,1 mm und 0,5 mm liegen. Im Unterschied zu der genannten Ausführungsform bei der das gesamte Gehäuseteil zu der Seitenwand beabstandet ist, kann es möglich sein, den Abstand von 0,5 mm im Bereich einer Aussparung bereitzustellen, wenn der restliche Abschnitt des Gehäuseteils ausreichend stabil ist. Oben waren ja Stabilitätsgründe dafür genannt worden, dass ein Abstand von 0,5 mm nicht unbedingt eingehalten werden kann, wenn eine Vielzahl von Klemmen in einem Leitungsschutzschalter bereitgestellt ist.The recess can basically be shaped as desired. For example, but it has an inner surface which lies in a plane which is parallel to a plane in which the remaining width portion of the housing part, to which the side wall faces. In this case, the inner surface of the recess is nothing more than the inner surface of the portion of the housing part displaced by a predetermined distance, this offset being limited by a predetermined distance to the area of a recess and not to the entire portion of the housing part (ie a wall of the housing part as a whole) must be extended. The predetermined distance may be between 0.1 mm and 0.5 mm. In contrast to the said embodiment in which the entire housing part is spaced from the side wall, it may be possible to provide the spacing of 0.5 mm in the region of a recess when the remaining portion of the housing part is sufficiently stable. Stability reasons have been mentioned above for the fact that a distance of 0.5 mm can not necessarily be maintained if a plurality of terminals is provided in a circuit breaker.

Ein in
Eine der Knickstelle 46 entsprechende Knickstelle 48 gibt es auch bei der Innenoberfläche des Abschnitts 36 des Gehäuseteils 14, zu welchem die Seitenwand 26 weist. Diese Knickstelle 48 trennt einen Breitenabschnitt 50 des Abschnitts, dessen Innenoberfläche in einer Ebene E1' liegt, von einem Breitenabschnitt 54, dessen Innenoberfläche in einer Ebene E2' liegt. Bevorzugt ist vorgesehen, dass die Ebenen E1 und E1' einerseits und die Ebenen E2 und E2' andererseits zueinander parallel sind, so dass die Ebenen E1' und E2' ebenfalls um einen Winkel α gegenüber verdreht sind. Diese Bedingung ist jedoch für das Funktionieren der Erfindung nicht notwendig. Von Bedeutung ist vielmehr, dass anders als im Stand der Technik gemäß
Da es nur auf den Bereich ankommt, in den die Seitenwände 26 und 28 hineinschwenken, kann auch eine einfache Aussparung 54 im Gehäuseteil 12 und eine Aussparung 56 im Gehäuseteil 14 genügen, um zu verhindern, dass die Seitenwände 28 bzw. 26 Gehäuseteile 12 bzw. 14 berühren. Die Aussparungen 54 und 56 können so gestaltet sein, dass im Bereich der Aussparung das Gehäuseteil 12 eine Innenoberfläche hat, welche in einer Ebene E4 liegt, welche zu einer Ebene E3 parallel ist, in der der restliche Abschnitt des Gehäuseteils 12, zu dem die Seitenwand 28 weist, liegt. Entsprechendes gilt für Teilabschnitte des Gehäuseteils 14, welche in einer Ebene E3' (außerhalb der Aussparung 56, aber gegenüber der Seitenwand 26) bzw. E4' (im Bereich der Aussparung 56) liegen.Since it only depends on the area in which the
Durch eine spezifische Formgebung der Gehäuseteile 12 und 14 ist erfindungsgemäß gewährleistet, dass nur an den Stellen Material beseitigt wird, an denen es für ein Verdrehen der Seitenwände 26 und 28 notwendig ist, wenn diese keine Kräfte auf die Gehäuseteile 12 und 14 ausüben sollen. Im übrigen Bereich der Gehäuseteile 12 und 14, d. h. insbesondere im übrigen Bereich der Abschnitte 34 und 36, zu denen die Seitenwände 28 bzw. 26 weisen, kann die Wandstärke der Gehäuseteile 12 und 14 dicker bleiben. Damit ist eine ausreichende Stabilität gewährleistet. Die Gehäuseteile 12 und 14 sind also nur in einem kleinen Bereich geschwächt, und ihre Herstellbarkeit und Funktionsfähigkeit ist nicht beeinträchtigt. Vielmehr wird das Problem der Ausübung von Kräften durch die Seitenwände 26 und 28 beseitigt.By a specific shape of the
