In einer weiteren sehr vorteilhaften Ausführungsform der Erfindung weist die Wand der Schmalseite des Gehäuses an den Längsseiten der ersten Gehäuseöffnung erste Führungsmittel auf. An den Längsseiten des zweiten Schenkels des Klemmenabdeckteils sind' zweite Führungsmitteln vorgesehen. Die ersten und zweiten Führungsmittel wirken zur Führung des Klemmenabdeckteils zusammen. Dabei können vorteilhafterweise die ersten Führungsmittel längserstreckte Nuten und die zweiten Führungsmittel Schnapphaken sein. Der Vorteil dieser Ausgestaltungsform liegt darin, dass das Klemmenabdeckteil bei geschlossenem Gehäuse von außen in den Klemmraum eingeführt werden kann und dabei auf die Klemmschraube und die erste Gehäuseöffnung aufklipsbar ist.In a further very advantageous embodiment of the invention, the wall of the narrow side of the housing has first guide means on the longitudinal sides of the first housing opening. On the longitudinal sides of the second leg of the terminal cover part 'second guide means are provided. The first and second guide means cooperate to guide the terminal cover member. Advantageously, the first guide means may be longitudinally extending grooves and the second guide means may be snap hooks. The advantage of this embodiment is that the terminal cover can be inserted from the outside into the terminal space with the housing closed and can be clipped onto the clamping screw and the first housing opening.

Durch die führende Wechselwirkung der ersten mit den zweiten Führungsmitteln ist das Klemmenabdeckteil dann nach dem Einführen in dem Klemmraum längsverschieblich gehalten.Due to the leading interaction of the first and the second guide means, the terminal cover part is then held longitudinally displaceable after insertion into the clamping space.

Eine alternative, auch sehr vorteilhafte Ausführungsform der Erfindung sieht vor, dass das Klemmenabdeckteil eine L-Form aufweist, mit einem ersten Schenkel, der eine ringförmige Durchbrechung aufweist. Die Durchbrechung ist bei der Montage des Klemmenabdeckteils von der Klemmschraube im Bereich ihres Klemmendes durchgriffen. In einer vorteilhaften Ausgestaltung ist der erste Schenkel mit der ringförmigen Durchbrechung mit einer Nut am Klemmende der Klemmschraube gekoppelt. Ein Vorteil dieser Ausgestaltungsform liegt darin, dass das Klemmenabdeckteil damit unverlierbar mit der Klemmschraube verbunden ist.An alternative, also very advantageous embodiment of the invention provides that the terminal cover part has an L-shape, with a first leg having an annular opening. The opening is penetrated during assembly of the terminal cover of the clamping screw in the region of its terminal end. In an advantageous embodiment, the first leg is coupled to the annular opening with a groove at the terminal end of the clamping screw. An advantage of this embodiment is that the terminal cover is thus captive connected to the clamping screw.

In einer besonders vorteilhaften Ausführungsform kann die Klemmschraube dabei eine kopffreie Bolzenschraube sein. Denn da das Klemmenabdeckteil an dem Klemmende der Klemmenschraube angebracht ist, ist die Ausgestaltung des Betätigungsendes der Klemmenschraube für die vorliegende Erfindung nicht von Bedeutung. Die Verwendung einer kopffreien Bolzenschraube bietet allerdings den Vorteil, dass diese sehr tief und vollständig in den Klemmkörper eingeschraubt werden kann und darüber hinaus als sehr preiswertes Massenteil zur Verfügung steht.In a particularly advantageous embodiment, the clamping screw can be a head-free bolt screw. Because the terminal cover part is attached to the terminal end of the terminal screw, the configuration of the operation end of the terminal screw is not important to the present invention. However, the use of a head-free bolt provides the advantage that it can be very deeply and completely screwed into the clamp body and is also available as a very inexpensive mass part available.

Weiterhin vorteilhaft ist eine Ausführungsform eines erfindungsgemäßen Installationsschaltgerätes, bei dem das Klemmenabdeckteil wenigstens teilweise in dem Klemmenaufnahmeraum zwischen dem Klemmkörper und der Innenseite der Schmalseitenwandung geführt ist. Es kann dabei vorteilhafterweise mit seinem zweiten Schenkel in dem Klemmenaufnahmeraum zwischen dem Klemmkörper und der Innenseite der Schmalseitenwandung geführt sein. Auf diese Weise ist das Klemmenabdeckteil Platz sparend im Gehäuseinneren untergebracht und durch unbeabsichtigte Beschädigung von der Außenseite her geschützt.Also advantageous is an embodiment of a service switching device according to the invention, in which the terminal cover is guided at least partially in the terminal receiving space between the clamping body and the inside of the narrow side wall. It may advantageously be performed with its second leg in the terminal receiving space between the clamping body and the inside of the narrow side wall. In this way, the terminal cover is space-saving housed inside the housing and protected by accidental damage from the outside.

Bezüglich der Klemmenschraube sieht eine sehr vorteilhafte Ausführungsform vor, dass diese an dem Klemmende eine umlaufende Nut aufweist, in der das Klemmenäbdeckteil verrastbar ist. Eine solche umlaufende Nut kann auch in bereits vorgefertigte Schrauben während der Fertigung eingebracht werden.With regard to the terminal screw, a very advantageous embodiment provides that it has a circumferential groove at the terminal end, in which the terminal cover part can be latched. Such a circumferential groove can also be introduced into already prefabricated screws during manufacture.

Eine weitere vorteilhafte Ausführungsform bezüglich der Klemmenschraube sieht vor, dass diese an dem Klemmende einen Koppelabsatz aufweist, mit dem das Klemmenabdeckteil mitnehmbar gekoppelt werden kann. Eine Form des Koppelns kann dabei in einem Aufklipsen bestehen.A further advantageous embodiment with respect to the terminal screw provides that it has a coupling paragraph at the terminal end, with which the terminal cover can be mitnehmbar coupled. A form of coupling may consist of clipping on.

Weiterhin kann an dem Koppelabsatz eine Druckplatte zum Andrücken des Anschlussleiters oder der Sammelschiene gegen die Stromschiene angebracht sein. Die Druckplatte dient im Zusammenwirken mit dem Koppelabsatz in diesem Fall zum Erzeugen der Nut, auf die das Klemmenabdeckteil aufgeklipst werden kann.Furthermore, a pressure plate for pressing the connecting conductor or the busbar against the busbar may be attached to the coupling paragraph. The pressure plate is used in cooperation with the coupling paragraph in this case to generate the groove on which the terminal cover can be clipped.

In einer besonders vorteilhaften Ausführungsform ist die Druckplatte an dem Klemmende der Klemmenschraube drehbar geführt. Wenn nämlich zwischen der Druckplatte und der Stromschiene ein Anschlussleiter eingesetzt werden soll, dann könnte sich der Anschlussleiter beim Zudrehen der Klemmenschraube verdrehen; dies kann verhindert werden, wenn die Druckplatte drehbar an der Klemmenschraube geführt ist.In a particularly advantageous embodiment, the pressure plate is rotatably guided at the clamping end of the clamping screw. Namely, if a connection conductor is to be used between the pressure plate and the busbar, then the connection conductor could twist when the clamping screw is screwed in; This can be prevented if the pressure plate is rotatably guided on the terminal screw.

Die Ausführung mit der Druckplatte erlaubt auch, den ersten Schenkel des L-förmigen Klemmenabdeckteils ringförmig auszuführen und ihn mit der inneren Ausnehmung des Rings über den Koppelabsatz zu führen. Mit dem Aufsetzen und befestigen der Druckplatte wird dann eine Verliersicherheit des Klemmenabdeckteils erreicht. Eine bevorzugte Art der Befestigung der Druckplatte auf dem Koppelabsatz ist dabei das Nieten.The pressure plate design also allows the first leg of the L-shaped terminal cover member to be annular and guide it to the inner recess of the ring over the coupling shoulder. With the placement and attach the pressure plate then a loss of security of the terminal cover is achieved. A preferred way of securing the pressure plate on the coupling heel is riveting.

Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments and improvements of the invention and further advantages can be taken from the further subclaims.

In den Figuren sind gleiche oder gleichwirkende Bauteile oder Elemente jeweils mit den gleichen Bezugsziffern versehen, auch wenn sie bei verschiedenen Ausführungsvarianten in leicht abgewandelter Form gestaltet sind.In the figures, the same or equivalent components or elements are each provided with the same reference numerals, even if they are designed in different embodiments in a slightly modified form.

Die Figur 1 zeigt schematisch eine Teilansicht eines Installationsschaltgerätes 1 mit einer vorderen Frontseite 2, einer hinteren Frontseite 3, einer der Frontseite gegenüberliegenden Befestigungsseite 4, einer die vordere und die hintere Frontseite verbindenden vorderen Schmalseite 5, einer die hintere Frontseite 3 und die Befestigungsseite 4 verbindenden hinteren Schmalseite 6 und zwei Breitseiten 7, von denen nur eine in der Figur 1 sichtbar ist.The FIG. 1 schematically shows a partial view of a service switching device 1 with a front front 2, a rear front 3, a front side opposite mounting side 4, a front and the rear front connecting front narrow side 5, the rear front 3 and the mounting side 4 connecting the rear narrow side. 6 and two broadsides 7, of which only one in the FIG. 1 is visible.

Im Bereich zwischen der hinteren Frontseite 3 und der hinteren Schmalseite 6 ist im Inneren des Gehäuses 8 des Installationsschaltgerätes ein Klemmenaufnahmeraum (hier nicht sichtbar) gebildet; in dem eine Anschlussklemme 10 (siehe Figur 2) gehalten ist. Die Anschlussklemme 10 umfasst eine von der hinteren Frontseite 3 durch eine Klemmenöffnung 9 hindurch zugängliche Klemmenschraube 24 sowie einen vorderen Klemmraum 20 und einen hinteren Klemmraum 21, welche von der Frontseite her gesehen hintereinander angeordnet und durch eine vordere 91 und eine hintere Gehäuseöffnung 92 in der hinteren Schmalseite 6 des Gehäuses für den Anschluss eines Anschlussleiters oder einer Sammelschiene beziehungsweise der Anschlussfahne einer Sammelschiene zugänglich sind.In the area between the rear front side 3 and the rear narrow side 6, a terminal receiving space (not visible here) is formed inside the housing 8 of the service switching device; in which a terminal 10 (see FIG. 2 ) is held. The terminal 10 comprises a terminal screw 24 accessible from the rear front 3 through a terminal opening 9 and a front terminal space 20 and a rear terminal space 21 arranged one behind the other viewed from the front and through a front 91 and a rear housing opening 92 in the rear Narrow side 6 of the housing for the connection of a connecting conductor or a busbar or the terminal lug of a busbar are accessible.

Die erste, vordere Gehäuseöffnung 91 besitzt in etwa eine sich in Längsrichtung der hinteren Schmalseite 6 erstreckende Rechteckkontur und dient dem Anschluss von Anschlussdrähten. Die zweite, hintere Gehäuseöffnung 92 ist in einem rinnenförmigen Absatz in der hinteren Schmalseite 6 angebracht und besitzt eine quer liegende Rechteckkontur. Sie ist für das Anklemmen der Anschlussfahne einer Sammelschiene vorgesehen.The first, front housing opening 91 has an approximately in the longitudinal direction of the rear narrow side 6 extending rectangular contour and serves for the connection of connecting wires. The second, rear housing opening 92 is mounted in a channel-shaped shoulder in the rear narrow side 6 and has a transverse rectangular contour. It is intended for clamping the terminal lug of a busbar.

Die Figur 2 zeigt in einer schematischen Schnittdarstellung eine Ausführungsform einer erfindungsgemäßen Anschlussklemme 10. Diese umfasst einen Klemmkörper 12, welcher zylindrisch oder auch mit kastenförmiger Außenkontur ausgeführt sein kann und einen im Inneren gelegenen Klemmraum für die Aufnahme der anzuklemmenden Anschlussleiter aufweist. In der oberen, also in der der Klemmenöffnung 9 zugewandten Hälfte des Klemmkörpers 12 trägt dieser ein Innengewinde 23, in welches eine ein entsprechendes Außengewinde 25 tragende Klemmenschraube 24 eingeschraubt und in Richtung des Richtungspfeiles 50 eingeschraubt und herausgedreht werden kann.The FIG. 2 shows a schematic sectional view of an embodiment of a connecting terminal 10 according to the invention. This comprises a clamping body 12, which may be cylindrical or with box-shaped outer contour and having a clamping space located in the interior for receiving the terminals to be clamped. In the upper, ie in the terminal opening 9 facing half of the clamp body 12 of this carries an internal thread 23, in which a corresponding external thread 25 bearing screw terminal screwed 24 and screwed in direction of the arrow 50 and can be unscrewed.

Die Klemmenschraube 24 hat ein Betätigungsende 26 mit einem Schlitz 28 für den Eingriff eines Betätigungswerkzeuges, beispielsweise eines Schraubendrehers, und ein dem Betätigungsende 26 gegenüberliegendes Klemmende 30, mit dem ein Anschlussleiter (hier nicht dargestellt) durch Druck gegen eine Stromschiene 36 festklemmbar ist. Der Schlitz 28 kann dabei alle möglichen bekannten Ausgestaltungen beziehungsweise Profile zum Zusammenwirken mit einer Vielzahl von bekannten Betätigungswerkzeugen haben, beispielsweise ein Kreuzschlitz, ein Pozidrive, ein Torx-Profil, es kann aber auch eine Kombination von verschiedenen Profilen verwendet werden.The terminal screw 24 has an actuating end 26 with a slot 28 for engagement of an actuating tool, such as a screwdriver, and the actuating end 26 opposite terminal end 30, with a connection conductor (not shown here) by pressure against a busbar 36 is clamped. The slot 28 may have all possible known configurations or profiles for interaction with a variety of known operating tools, such as a Phillips, a Pozidrive, a Torx profile, but it can also be a combination of different profiles are used.

Die Stromschiene 36 ist bei der hier gezeigten Ausführungsform im Inneren des Klemmraums gehäusefest gelagert. Sie unterteilt den Klemmraum in einen vorderen Klemmraum 20 zwischen der Stromschiene 36 und der Klemmenöffnung 9, sowie einen hinteren Klemmraum 21 zwischen der Stromschiene 36 und dem den Klemmkörper 12 zur Befestigungsseite 4 hin begrenzenden Begrenzungssteg 17. Der Klemmkörper 12 ist in dem Klemmenaufnahmeraum längsverschieblich parallel zur Schmalseitenwand geführt. Durch das Eindrehen der Klemmschraube wird zunächst das Klemmende der Klemmschraube gegen den in dem vorderen Klemmraum eingeführten Leiter gedrückt und klemmt diesen gegen die Stromschiene. Bei Fortsetzung der Eindrehbewegung der Klemmschraube stütz diese sich gewissermaßen an der Stromschiene ab und der Klemmkörper wird nach oben in Richtung auf die Frontseite hin bewegt, bis schließlich der Begrenzungssteg 17 die in den hinteren Klemmraum 21 eingeführte Sammelschiene gegen die Stromschiene drückt.The busbar 36 is mounted fixed to the housing in the interior of the terminal space in the embodiment shown here. It divides the terminal space in a front terminal space 20 between the busbar 36 and the terminal opening 9, and a rear terminal space 21 between the busbar 36 and the clamping body 12 to the mounting side 4 limiting limiting web 17. The clamping body 12 is longitudinally displaceable in the terminal receiving space parallel to Narrow side wall out. By screwing in the clamping screw, the clamping end of the clamping screw is first pressed against the conductor inserted in the front clamping space and clamps it against the busbar. When continuing the screwing movement the clamping screw supports it to a certain extent on the busbar and the clamping body is moved upward in the direction of the front side, until finally the limiting web 17 presses the inserted into the rear terminal space 21 busbar against the busbar.

Die Stromschiene 36 läuft ins Geräteinnere hin in ein einen Anschlussleiter bildendes Abgangsende 37 aus, an dem weitere Komponenten und Baugruppen des Installationsschaltgerätes angeschlossen sind, beispielsweise Auslöser oder Kontaktstellen. An ihrem freien Ende ist die Stromschiene 36 U-förmig abgebogen, so dass ein Bogenstück 361 und ein daran anschließender, parallel zur Stromschiene in dem hinteren Klemmraum 21 verlaufender Schenkel 362 entstehen. Wenn nun in den hinteren Klemmraum 21 die Anschlussfahne einer Sammelschiene eingeführt wird, so wird diese von dem Schenkel 362 und dem Begrenzungssteg 17 beidseitig umfasst, und durch das anziehen der Klemmschraube 24 ist ein guter mechanischer und elektrischer Kontakt sichergestellt.The busbar 36 runs into the interior of the device in a connecting conductor forming a drain end 37, are connected to the other components and modules of the service switching device, such as triggers or contact points. At its free end, the busbar 36 is bent in a U-shape, so that a curved piece 361 and an adjoining, parallel to the busbar in the rear terminal space 21 extending leg 362 arise. Now, if the terminal lug of a busbar is inserted into the rear terminal space 21, this is on both sides of the leg 362 and the limiting web 17, and by tightening the clamping screw 24 a good mechanical and electrical contact is ensured.

Die Klemmenschraube 24 kann an ihrem Klemmende 30 eine Druckplatte 32 tragen.The terminal screw 24 may carry a pressure plate 32 at its terminal end 30.

Wenn der Klemmenschraube 30 auf die Stromschiene 36 aufgeschraubt ist, so wie in der Figur 2 dargestellt, also ohne eingeführten Anschlussleiter im vorderen Klemmraum 20, so ist durch die vordere Gehäuseöffnung 91 der Schaft der Klemmenschraube 24 für eine ungewollte Berührung zugänglich. Um diese Gefahrenquelle zu beseitigen, ist in einer umlaufende Nut 301 an dem Klemmende 30 der Klemmschraube 24 ein Klemmenabdeckteil 60 aufgesteckt.When the terminal screw 30 is screwed onto the bus bar 36, as in the FIG. 2 shown, so without inserted connection conductor in the front terminal space 20, so is accessible through the front housing opening 91 of the shank of the terminal screw 24 for an unwanted contact. To eliminate this source of danger, a terminal cover 60 is attached in a circumferential groove 301 at the terminal end 30 of the clamping screw 24.

Das Klemmenabdeckteil 60 (siehe Figur 4) hat in etwa eine L-Form und ist an einem ersten, dem kurzen Schenkel 62 gabelförmig ausgebildet. Die dadurch entstandenen beiden federnder in Teilschenkel 63, 64 umfassen eine Innenkontur, die in etwa der Außenkontur der umlaufende Nut 301 an dem Klemmende 30 der Klemmenschraube 24 entspricht, so dass das Klemmenabdeckteil 60 mit dem ersten Schenkel 62 an dem Klemmende 30 der Klemmenschraube 24 verrastbar angefügt werden kann. Das Klemmenabdeckteil 60 wird dadurch in der Bewegungsrichtung 50 der Klemmenschraube 24 von dieser beim Ein - und Ausdrehen jeweils mitgenommen.The terminal cover 60 (see FIG. 4 ) has approximately an L-shape and is fork-shaped on a first, the short leg 62. The resulting two resilient in part legs 63, 64 include an inner contour which corresponds approximately to the outer contour of the circumferential groove 301 at the clamping end 30 of the terminal screw 24, so that the terminal cover 60 with the first leg 62 at the terminal end 30 of the clamping screw 24 can be latched can be added. The terminal cover part 60 is thereby entrained in the direction of movement 50 of the clamping screw 24 of this when turning in and out.

Etwa senkrecht zu dem ersten Schenkel 62 des Klemmenabdeckteils 60 verläuft ein plattenförmiger zweiter Schenkel 66. Der plattenförmige Schenkel 66 deckt denjenigen Teil des vorderen Klemmraums 20, der oberhalb des Klemmendes 30 der Klemmenschraube 24 liegt, von der Seite der vorderen Gehäuseöffnung 61 her berührungssicher ab.Approximately perpendicular to the first leg 62 of the terminal cover 60 extends a plate-shaped second leg 66. The plate-shaped leg 66 covers that part of the front terminal space 20, which is above the terminal end 30 of the terminal screw 24, from the side of the front housing opening 61 from touch safe.

In dem Klemmenaufnahmeraum ist die erfindungsgemäße Anschlussklemme 10 mit dem Klemmenabdeckteil 60 so angebracht, das der plattenförmige zweite Schenkel 66 des Klemmenabdeckteils 60 an der Innenseite der Gehäusewand im Bereich der vorderen Gehäuseöffnung 91 parallel zum Verlauf der hinteren Schmalseite 6 geführt ist. Dadurch ist eine Beschädigung des Klemmenabdeckteils durch unsachgemäße Behandlung des Installationsschaltgeräte es vermieden.In the terminal receiving space, the terminal 10 of the invention with the terminal cover 60 is mounted so that the plate-shaped second leg 66 of the terminal 60 is guided on the inside of the housing wall in the region of the front housing opening 91 parallel to the course of the rear narrow side 6. As a result, damage to the terminal cover is avoided by improper handling of the installation switching devices.

Das Klemmenabdeckteil 60 besteht aus einem Isolierwerkstoff, beispielsweise aus Kunststoff.The terminal cover 60 is made of an insulating material, such as plastic.

Die Klemmenschraube 24 ist bei den hier gezeigten Ausführungsformen eine kopflose Bolzenschraube, auch Madenschraube genannt. Diese hat den Vorteil, dass sie vollständig in dem Klemmkörper 12 eingeschraubt werden kann, ohne dass ein Kopf nach außen überstehen würde. Doch selbstverständlich könnte eine erfindungsgemäße Anschlussklemme auch mit einer Kopfschraube ausgeführt sein.The terminal screw 24 is in the embodiments shown here, a headless bolt, also called grub screw. This has the advantage that it can be completely screwed into the clamp body 12, without a head would survive to the outside. But of course, a terminal according to the invention could also be designed with a cap screw.

Die umlaufende Nut 301 lässt sich auf sehr günstige Art, beispielsweise durch Drehen, bei der ansonsten bekannten Fertigung der Klemmenschrauben einbringen.The circumferential groove 301 can be very cheap way, for example, by turning, bring in the otherwise known production of terminal screws.

In der Figur 3 ist eine alternative Ausgestaltungsart für eine Klemmenschraube 24 zur Verwendung in einer erfindungsgemäßen Anschlussklemme 10 mit einem .Klemmenabdeckteil 60 gezeigt. Es sind dabei an dem Klemmende 30 der Klemmenschraube 24 eine vorderer Absatz 302 und ein hintere Absatz 304 ausgebildet, wobei der vordere Absatz einen kleineren Außendurchmesser hat als der Schraubenschaft, und der hintere Absatz 304 einen kleineren Außendurchmesser hat als der vordere Absatz 302.In the FIG. 3 For example, an alternative embodiment for a terminal screw 24 for use in a terminal 10 of the present invention having a terminal cover 60 is shown. In this case, a front shoulder 302 and a rear shoulder 304 are formed on the clamping end 30 of the clamping screw 24, wherein the front shoulder has a smaller outer diameter than the screw shaft, and the rear shoulder 304 has a smaller outer diameter than the front shoulder 302.

Der vordere Absatz 302 dient zum Anklipsen des Klemmenabdeckteils 60 mit seinem ersten Schenkel 62.The front shoulder 302 serves for clipping the terminal cover part 60 with its first leg 62.

Der hintere Absatz 304 bildet eine Art Stift, und er dient zum Aufnieten des der Druckplatte. Dazu ist die Druckplatte 32 mit einer inneren Ausnehmung versehen, die es gestattet, sie mit dieser Ausnehmung über den Stift 304 zuführen. Die freie Länge des Stifters 304 ist dabei mit der Dicke der Druckplatte 32 so abgestimmt, dass nach dem aufsetzen der Druckplatte 32 auf den Stift 304 dieser die Druckplatte 32 noch um ein kurzes Stück überragt. Dieses überragende Stück dient zum anschließenden Vernieten der Druckplatte 32, indem es platt gedrückt wird.The rear shoulder 304 forms a kind of pin, and it serves to rivet the pressure plate. For this purpose, the pressure plate 32 is provided with an inner recess, which allows them to perform with this recess via the pin 304. The free length of the stirrer 304 is matched with the thickness of the pressure plate 32 so that after placing the pressure plate 32 on the pin 304 of this, the pressure plate 32 still surmounted by a short distance. This towering piece serves to subsequently rivet the pressure plate 32 by pressing it flat.

Die Vernietung der Druckplatte 32 kann dabei so ausgeführt werden, dass diese auf dem Stift 304 noch drehbar bleibt. Somit kann erreicht werden, dass beim Festschrauben des Leiters auf der Stromschiene 36 sich die Druckplatte nicht dreht. Das hat den Vorteil, dass es keinen mechanischen Abrieb auf dem Anschlussleiter durch eine Drehbewegung relativ zu dem Anschlussleiter gibt.The riveting of the pressure plate 32 can be carried out so that it still remains rotatable on the pin 304. Thus, it can be achieved that when screwing the conductor on the busbar 36, the pressure plate does not rotate. This has the advantage that there is no mechanical abrasion on the connecting conductor due to a rotational movement relative to the connecting conductor.

Insgesamt hat sich nach dem Vernieten der Druckplatte 32 auf dem Stift 304 somit zwischen der Druckplatte 32 und dem Klemmende 30 der Klemmenschraube 24 eine Art Nut ergeben, welche ein Verrutschen des auf dem vorderen Absatz 302 aufgeklipsten Klemmenabdeckteils nach unten hin verhindert.Overall, after riveting the pressure plate 32 on the pin 304 thus between the pressure plate 32 and the terminal end 30 of the terminal screw 24, a kind of groove, which prevents slipping of the clipped on the front paragraph 302 terminal cover part downwards.

Auch die zur Realisierung dieser Ausführungsform einer erfindungsgemäßen Anschlussklemme nötige Modifizierung handelsüblicher Klemmenschrauben, beispielsweise kopffreier Bolzenschrauben, stellt keinen großen Aufwand dar. Die modifizierten Bolzenschrauben können aus handelsüblichen Schrauben durch einfaches abdrehen der beiden Absätze 302, 304 an dem freien Schraubenende hergestellt werden. Wegen der sehr hohen Stückzahlen sollte sich auch kein Kostennachteil gegenüber nicht modifizierten Bolzenschrauben ergeben.The modification necessary for the realization of this embodiment of a terminal according to the invention modification of commercially available terminal screws, such as head-free bolts, is not a major effort. The modified studs can be made of commercially available screws by simply turning off the two paragraphs 302, 304 at the free end of the screw. Because of the very high quantities, there should be no cost disadvantage compared to unmodified stud bolts.

Es werde nun die Figur 5 betrachtet. Hier weist die Wand der Schmalseite 6 an ihren Längsstegen erste Führungsmittel 100 in Form einer hinterschnittenen, längserstreckten Nut auf. An den Längsseiten des zweiten, nach oben weisenden Schenkels des Klemmenabdeckteils weist dieses zweite Führungsmittel 102 in Form von Rasthaken oder Schnapphaken auf. Das Klemmenabdeckteil in dieser Ausführungsform kann von außen bei geschlossenem Gehäuse in die erste Gehäuseöffnung 91 eingeklipst werden, wobei der erste, gabelförmige Schenkel des Klemmenabdeckteils in die Nut am Klemmende der Schraube trifft und dort einschnappt, und die Rasthaken in der Nut verrasten.It will now be the FIG. 5 considered. Here, the wall of the narrow side 6 at its longitudinal webs first guide means 100 in the form of an undercut, elongated groove. On the longitudinal sides of the second, upwardly pointing leg of the terminal cover part, this second guide means 102 in the form of latching hooks or snap hooks. The terminal cover member in this embodiment can be clipped from the outside with the housing closed in the first housing opening 91, wherein the first forked leg of the terminal cover in the groove on The clamping end of the screw strikes and snaps in place, and the locking hooks engage in the groove.

Eine weitere Ausführungsform zeigt die Figur 6. Dort ist das Klemmenabdeckteil 60 als Blechwinkel ausgeführt. Sein erster Schenkel weist die oben bereits erwähnte Durchbrechung auf (in der Darstellung nach Figur 6 verborgen) und ist mit der Klemmschraube an deren Klemmende direkt drehbar vernietet. Der Blechwinkel ist zu der Seite, die in eingebautem Zustand von außen berührbar ist, mit einem Isolierstoff überzogen, so dass eine Isolierschicht 95 entsteht. Es kann sich dabei beispielsweise um eine aufgespritzte Kunststoffschicht handeln. Das Klemmenabdeckteil wird dadurch sehr stabil und preisgünstig herstellbar.Another embodiment shows the FIG. 6 , There, the terminal cover 60 is designed as a sheet metal angle. His first leg has the above-mentioned opening (in the illustration after FIG. 6 hidden) and is riveted directly to the clamping screw at the terminal end. The sheet metal angle is coated with an insulating material to the side, which is externally touchable in the installed state, so that an insulating layer 95 is formed. It may be, for example, a sprayed-on plastic layer. The terminal cover is characterized very stable and inexpensive to produce.
