Definitions
- the invention relates to an electric power strip, comprising a housing, a movable lid and a lever-like handle inserted on the lid and a pivotally mounted on the lid, a handle part exhibiting release element.
- Out DE 29605800 U1 is a load switch bar with a hinged at its lid release element in the form of a flap known, are arranged on the turn hook-shaped extensions, which limit the length of the lid arranged on the slots.
- the flap is provided with a handle part.
- a first pair of levers is pivotally connected, which carries a handle.
- a second pair of levers is connected to the lid via a pin pair guided in the oblong holes.
- the blockage against the removal of the lid is realized as follows: In the operating position, the flap is folded down, whereby the freedom of movement of the pin is limited and consequently the withdrawal of the lid connected to the handle is prevented from the housing.
- the operation of the blockade always requires a tedious unlocking and locking of the release element, so the flap.
- the release element is rotatable arranged opposite to a lying transverse to the longitudinal direction of the load switching strip axis of rotation.
- EP 0 563 530 A1 a load switch bar with a housing and switch cover with a plate-shaped fuse element known.
- the securing element has projections which engage in special recesses of the housing.
- EP-A-0802551 discloses a power switch strip according to the preamble of claim 1.
- the object of the invention is to develop an electric power strip with a simplified operation of the blockage against the removal of the lid.
- spatulate refers to the shape of a flat element, such as cut flat iron or medical flat spatula. Such a flat element may be rounded at least at one end.
- the release element may have at least one continuous, preferably in the middle region opening into which a arranged on the partition wall pin or bolt engages, so that the release element is pivotally connected to the pin.
- the release element may have stop elements which abut when pivoted in the transverse direction against corresponding, arranged on the cover stop elements and thereby limit the pivoting movement.
- the said stop elements of the release element are preferably arranged on a handy handle part.
- the release element can have at least one further stop element, which is arranged on an end opposite the grip part.
- the stop member may be flattened and rounded so that it can slide over corresponding guide surfaces within the lid or housing. The adjustment of the release element thus takes place in a plane which is defined by the transverse partition wall of the lid.
- the gripping part of the release element can preferably be arranged in a transverse direction, ie transversely to the longitudinal axis of the Lids, within an opening incorporated in the lid slidably disposed along a curved line.
- the opening is preferably a slot opening.
- the release element is provided with at least one positioning element which can interlock with a seat element located in the cover.
- the toothing of the positioning elements with the Siztiatan improves the positional stability of the release element.
- the release element has two stable working positions, i. after the adjustment, the release element remains in the selected position without having to be supported and without having to carry out additional steps with the aid of the handle or the lever during removal of the complete lid from the apparatus.
- Another advantage is that prior to the onset of the complete lid in the housing no adjustment of the release element is required because unimpeded insertion of the complete lid in the housing of the circuit breaker is possible in any position of the release element.
- bottom and top used in the figure description refer to those in Fig. 1 shown vertically erected disconnector, the lower part 1 here “down” and the lid 3 "up” is.
- an electrical load switch bar also called disconnector.
- the load switch bar 100 comprises the complete lower part 1 with a housing 2 arranged thereon and the complete lid 3.
- the complete lid 3 (cf. Fig. 2 to 4 ) consists of a cover element 4, a handle 5, a sheet-to-spatula-shaped release element 6 and three transparent windows. 7
- the cover element 4 has a central web 28 and two mutually mirror-symmetrically arranged, downwardly disposed side parts 8, which are each provided with a laterally projecting pin 9 arranged thereon collar 10.
- the pins 9 are arranged mirror-symmetrically to one another on the longitudinal sides of the lid 4.
- the in Fig. 1 and 9 shown handle 5 has two side parts 13 with it incorporated, obliquely extending, elongated cutouts 12, into which the said pins 9 engage. Furthermore, 5 inwardly projecting, engaging in openings 11 pins 14 are introduced to the side parts 13 of the handle.
- the pins 14 are each provided with a collar 15th Mistake.
- first positioning elements 16 (see. Fig. 3 ) arranged in an open position of the load switch bar 100 in the in Fig. 9 shown openings 17 engage in the side parts 13 of the handle 5 and thereby the handle 5 in this open position (see. Fig. 12 ) hold.
- first guide rails 18 and second guide rails 19 are arranged.
- the guide rails 18, 19 are to the laterally arranged in the housing 2 guides 20 (see. Fig. 10 ) adapted to be displaceable therein.
- the first guide rails 18 each have an opening 21 which are compatible with the outwardly projecting positioning elements 22 of the handle 5. In the closed position or parking position of the circuit breaker, the positioning elements 22 engage in the openings 21, whereby the handle 5 is held in the closed position.
- the release element 6 has the shape of a provided with a handle portion 30 spatula 23 (see. FIGS. 6, 7 and 8th ), which at its handle portion 30 opposite end 49 a Stop element 41 carries.
- the stop element 41 is flattened and has two laterally arranged curves 52, 53, of which the rounding 52 form a sliding surface 43 and the rounding 53 form a sliding surface 45. Accordingly, the end 49 of the spatula 23 is rounded on both sides.
- a through opening 27 is arranged, into which a at a partition wall 24 (see. Fig. 5 ) of the lid member 4 arranged pin 25 is brought into latching engagement, as is the Fig. 13 can be seen.
- This connection allows a pivoting of the release element 6 in the transverse direction Q (see. Fig. 8 and it 14) relative to the lid member 4 along a in Fig. 8 schematically indicated arc line 51, in a plane E (see. Fig. 14 ) defined by said partition wall 24.
- the axis of rotation 47 (cf. Fig. 6 and 13 ) of the mounted release element 6 is arranged parallel to a longitudinal axis 48 of the cover element 4.
- the arcuate line 51 is described by a radius R whose center lies on the pin 25 or on the axis of rotation 47.
- the pin 25 has a collar 26 which prevents the pin 25 from being released from the opening 27 of the release element 6.
- the pin 25 and the collar 26 is divided into two parts (see. Fig. 5 ) to facilitate the engagement in the opening 27 by spring force.
- a rectangular opening 29 is arranged in the form of a Langlochöffnng in which the handle portion 30 of the release element 6 is accessible and along said arc 51 (see. Fig. 8 ) can be performed.
- the handle member 30 itself consists of a slightly concave central web 54 and two vertically projecting Side walls 31, 33 which in web-shaped stop members 32, 34 (see. FIGS. 6, 7 and 8th ) leak.
- the concavity of the central web 54 is ergonomically adapted to the thumb or fingers of the operator.
- an arrow 55 (see. FIGS. 6, 7 and 15 ), which in the present case shows the direction of release of the blockage.
- stop elements 35, 39 are introduced (see, in particular Fig. 8 ), which restrict the pivoting movement of the release element 6.
- a maximum pivoting of the release element 6 (see. Fig. 8 ) abut the two lying on the handle portion 30 stop members 32, 34 (either to the left or to the right) against the arranged in the opening 29 stop members 35, 39.
- On the handle portion 30 is still another, lying between the stop members 32, 34 and plane-parallel a flat side 50 of the spatula 23 arranged wall portion 36 (see. Fig. 6 ), on which in turn a positioning element 37 is introduced.
- the stop element 32 leans against the stop element 39, which is arranged in the rectangular opening 29 of the cover element 4.
- the positioning element 37 meshes with a likewise arranged in the rectangular opening 29 of the lid member 4 seat member 38 (see. Fig. 5 ), whereby an automatic displacement of the release element 6 is prevented.
- the other stop element 34 leans against the stop element 35 located in the rectangular opening 29.
- the positioning element 37 meshes with this position with a second seat member 40 (see. Fig. 5 ), which is also located in the rectangular opening 29 of the lid member 4, whereby an automatic displacement of the release element 6 is prevented.
- the arranged on the spatula 23 of the release element 6 stop element 41 comes after opening or parking the circuit breaker with a housing 2 located in another, in Fig. 13 shown stop element 42 in contact, whereby a removal of the complete lid 3 is prevented from the housing 2.
- the handle portion 30 of the release element 6 In order to remove the complete cover 3 from the housing 2, the handle portion 30 of the release element 6 should be as far as possible to the right, ie in the direction of arrow, to be moved. In this position, it comes to the displacement of the stop element 41 of the release element 6 behind the stop element 42 in the housing 2. The lid can be lifted. When re-inserting the complete lid 3 in the housing 2 for the purpose of closing or parking the disconnector, the handle portion 30 of the release element 6 may be in any position. After placing the lid, the release element 6 returns to the in Fig. 1 shown starting position.

Bekannt sind ebenfalls Konstruktionslösungen von Leistensicherheits-trennschaltern, bei denen am Deckel ein Element verschiebbar befestigt ist, das nach der Trennung die Bewegung eines Verbindungs-hebels einschränkt und das Herausnehmen des Deckels unmöglich macht.Also known are design solutions of breaker safety disconnectors in which an element is slidably mounted on the lid, which limits the movement of a connecting lever after separation and makes the removal of the lid impossible.
Die Aufgabe der Erfindung ist, eine elektrische Lastschaltleiste mit einer vereinfachten Bedienung der Blockade gegen das Herausnehmen des Deckels zu entwickeln.The object of the invention is to develop an electric power strip with a simplified operation of the blockage against the removal of the lid.
Diese Aufgabe ist durch eine elektrische Lastschaltleiste nach Anspruch 1 gelöst.This object is achieved by an electric power switch strip according to claim 1.
Der Begriff "spatelförmig" bezieht sich auf die Form eines Flachelementes, wie abgelängtes Flacheisen oder ärztlicher Flachspatel. Ein solches Flachelement kann an wenigstens einem Ende abgerundet sein.The term "spatulate" refers to the shape of a flat element, such as cut flat iron or medical flat spatula. Such a flat element may be rounded at least at one end.
Das Löseelement kann wenigstens eine durchgehende, vorzugsweise im mittlerem Bereich liegende Öffnung aufweisen, in die ein an der Trennwand angeordneter Stift oder Bolzen einrastet, so das das Löseelement schwenkbar am Stift verbunden ist.The release element may have at least one continuous, preferably in the middle region opening into which a arranged on the partition wall pin or bolt engages, so that the release element is pivotally connected to the pin.
Darüber hinaus kann das Löseelement Anschlagelemente aufweisen, die bei Verschwenkung in Querrrichtung gegen entsprechende, am Deckel angeordnete Anschlagelemente stoßen und dadurch die Schwenkbewegung einschränken. Die besagten Anschlagelemente des Löseelementes sind vorzugsweise an einem handlichen Griffteil angeordnet.In addition, the release element may have stop elements which abut when pivoted in the transverse direction against corresponding, arranged on the cover stop elements and thereby limit the pivoting movement. The said stop elements of the release element are preferably arranged on a handy handle part.
Ferner kann das Löseelement wenigstens ein weiteres Anschlagelement aufweisen, das an einem dem Griffteil gegenüber liegenden Ende angeordnet ist. Das Anschlagelement kann abgeflacht und abgerundet sein, so dass über entsprechende Leitflächen innerhalb des Deckels oder des Gehäuses gleiten kann. Die Verstellung des Löseelementes erfolgt also in einer Ebene, die durch die quer liegende Trennwand des Deckels definiert ist.Furthermore, the release element can have at least one further stop element, which is arranged on an end opposite the grip part. The stop member may be flattened and rounded so that it can slide over corresponding guide surfaces within the lid or housing. The adjustment of the release element thus takes place in a plane which is defined by the transverse partition wall of the lid.
Bei der Lastschaltleiste kann vorzugsweise das Griffteil des Löseelementes in einer Querrichtung, d. h. quer zur Längsachse des Deckels, innerhalb einer am Deckel eingearbeiteten Öffnung verschiebbar entlang einer Bogenlinie angeordnet sein. Die Öffnung ist vorzugsweise eine Langlochöffnung.In the case of the load-switching strip, the gripping part of the release element can preferably be arranged in a transverse direction, ie transversely to the longitudinal axis of the Lids, within an opening incorporated in the lid slidably disposed along a curved line. The opening is preferably a slot opening.
Vorteilhaft ist, wenn das Löselement mit wenigstens einem Positionierungselement versehen ist, das sich mit einem im Deckel befindlichen Sitzelement verzahnen kann. Die Verzahnung der Positionierungselemente mit den Siztelementen verbessert die Lagestabilität des Löseelementes.It is advantageous if the release element is provided with at least one positioning element which can interlock with a seat element located in the cover. The toothing of the positioning elements with the Siztelementen improves the positional stability of the release element.
Von Vorteil ist eine vereinfachte Bedienung der Deckelblockade im Vergleich zu bekannten Lösungen. Das Löseelement hat zwei stabile Arbeitsstellungen, d.h. nach der Verstellung verbleibt das Löseelement in der gewählten Position ohne dass es gestützt werden muss und ohne dass während des Herausnehmens des kompletten Deckels aus dem Apparat zusätzliche Schritte mit Hilfe des Handgriffs bzw. des Hebels durchgeführt werden müssen.An advantage is a simplified operation of the lid blockage in comparison to known solutions. The release element has two stable working positions, i. after the adjustment, the release element remains in the selected position without having to be supported and without having to carry out additional steps with the aid of the handle or the lever during removal of the complete lid from the apparatus.
Ein weiterer Vorteil besteht darin, dass vor dem Einsetzen des kompletten Deckels in das Gehäuse keine Verstellung des Löseelements erforderlich ist, denn ein ungehindertes Einsetzen des kompletten Deckels in das Gehäuse des Trennschalters ist bei beliebiger Position des Löseelements möglich.Another advantage is that prior to the onset of the complete lid in the housing no adjustment of the release element is required because unimpeded insertion of the complete lid in the housing of the circuit breaker is possible in any position of the release element.
