Abstract

The invention relates to a terminal board for the connection of electrical apparatuses. In such terminal boards, as are used especially for apparatuses in explosion-protected designs, the requirement exists to be able to connect the mains conductor with and without a cable shoe and the winding lead with a cable shoe, incorrect connection protection being ensured when connections are made with cable shoes. To this end, a terminal piece (3) is proposed which surrounds the connecting bolt (2) as a hollow-cylindrical part (31). The function of the connection without a cable shoe is carried out by a projection (32), which is connected to the hollow-cylindrical part (31) and is fitted with one or two threaded holes (33). The incorrect connection protection for the cable shoe connection of the mains conductor (4) is carried out by two cams (36) and that for the winding lead (5) is carried out by a slot (11) in the terminal board (1). <IMAGE>

Description

Die Erfindung betrifft eine Klemmenplatte für den Anschluß elektrischer Geräte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a terminal plate for connecting electrical devices according to the preamble of claim 1.

Eine derartige Klemmenplatte ist bereits bekannt (DE-B-24 10 046). Bei dieser bekannten Klemmenplatte sind die Netzleiter direkt am Anschlußstück und die Wicklungsableitung für das anzuschließende Gerät über einen Kabelschuh am Anschlußbolzen angeschlossen. Der Verdrehungsschutz dieser Anordnung wird durch zwei Vorsprünge des Anschlußstücks erreicht, die an der Kante der Klemmenplatte anliegen. Die beiden Vorsprünge bilden mit der Kante und der durch die im Querschnitt z-förmig gestaltete Ausführung des Anschlußstücks eine Öffnung, durch welche der Anschluß der Wicklungsableitung zum Anschlußbolzen hindurchgeführt ist. Einer weiteren Forderung entsprechend ist es nicht ohne weiteres möglich, den Netzleiter als Alternativlösung mit einem Kabelschuh unter Berücksichtigung der Verdrehsicherheit anzuschließen. Da das Anschlußstück vom Anschlußbolzen und der Kante der Klemmenplatte in seiner Lage fixiert ist, sind den Maßanforderungen bezüglich des einzuhaltenden Abstandes von der Bohrung für den Anschlußbolzen bis zu den Vorsprüngen des Anschlußstücks enge Grenzen gesetzt.Such a terminal plate is already known (DE-B-24 10 046). In this known terminal plate, the power conductors are connected directly to the connecting piece and the winding lead for the device to be connected is connected to the connecting bolt via a cable lug. The anti-rotation protection of this arrangement is achieved by two projections of the connecting piece, which abut the edge of the terminal plate. The two projections form an opening with the edge and through the design of the connecting piece, which has a z-shaped cross section, through which the connection of the winding lead to the connecting bolt is passed. According to a further requirement, it is not readily possible to connect the network conductor as an alternative solution with a cable lug, taking into account the security against rotation. Since the connector is fixed in position by the connector bolt and the edge of the terminal plate, the dimensional requirements regarding the distance to be maintained from the bore for the connector bolt to the projections of the connector are limited.

Der Erfindung liegt die Aufgabe zugrunde, eine Klemmenplatte der eingangs geschilderten Art soweit zu ertüchtigen, daß der Netzleiter mit und ohne Kabelschuh und die Wicklungsableitung zum anzuschließenden Gerät mit Kabelschuh unter Gewährleistung eines vollen Verdrehungsschutzes der Anschlüsse mit Kabelschuh anschließbar sind.The invention has for its object to provide a terminal plate of the type described to the extent that the power conductor with and without a cable lug and the winding lead to device to be connected with a cable lug can be connected with a full protection against rotation of the connections with a cable lug.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen konstruktiven Maßnahmen gelöst.This object is achieved by the design measures specified in the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß das Klemmenstück unabhängig von den Abmessungen der Klemmenplatte auf den Anschlußbolzen aufsetzbar ist, und daß der Verdrehungsschutz für die mit Kabelschuh angeschlossenen Leitungen durch einfache konstruktive Gestaltung des Klemmenstücks und der Klemmenplatte unter Einhaltung der Vorschriften des VDE und der Europanorm für explosionsgeschützte Geräte erreicht wird.The advantages achieved by the invention are that the terminal piece can be placed on the connecting bolt regardless of the dimensions of the terminal plate, and that the anti-rotation protection for the lines connected with a cable lug by simple structural design of the terminal piece and the terminal plate in compliance with the regulations of the VDE and the European standard for explosion-protected devices is achieved.

Vorteilhafte Aus- und Weiterbildungen des Gegenstandes nach Anspruch 1 sind den Unteransprüchen zu entehmen.Advantageous training and further developments of the subject matter according to claim 1 can be found in the subclaims.

So ist nach Anspruch 2 die Verdrehsicherheit des Kabelschuhs für den Netzleiter im einzelnen angegeben, wobei mit dem Klemmenstück verbundene Nocken die Bewegungsfreiheit des Kabelschuhs nach den Seiten behindern. Im Anspruch 5 ist der kabelschuhlose Anschluß des Netzleiters beschrieben. Hierbei wird der blanke Netzleiter in Schlaufenform um die Bohrung im Ansatz des Klemmenstücks gelegt und mittels eines Klemmbügels und einer Schraube elektrisch leitend verbunden und festgesetzt. Diese Verbindungsart wird für kleinere Querschnitte des Netzleiters bevorzugt. Bei größeren Querschnitten bedient man sich einer Lasche, die mittels zwei Schrauben mit dem Ansatz des Klemmenstücks verbunden wird, wobei der blanke Netzleiter zwischen der Lasche und dem Ansatz eingeklemmt wird (Anspruch 6). Schließlich gibt der Anspruch 7 die Besonderheiten der Ausgestaltung der Nut wieder, um die Verdrehsicherheit für die Wicklungsableitung mit einem Kabelschuh zu erreichen.Thus, according to claim 2, the security against rotation of the cable lug for the power conductor is specified in detail, with cams connected to the clamp piece hindering the freedom of movement of the cable lug to the sides. In claim 5 the cable lug-free connection of the power conductor is described. In this case, the bare network conductor is looped around the hole in the attachment of the terminal piece and connected and fixed in an electrically conductive manner by means of a clamping bracket and a screw. This type of connection is preferred for smaller cross-sections of the network conductor. In the case of larger cross sections, a tab is used, which is connected to the attachment of the terminal piece by means of two screws, the bare network conductor being clamped between the tab and the attachment (claim 6). Finally, claim 7 reflects the special features of the design of the slot in order to achieve the security against rotation for winding derivation with a cable lug.

Ausführungsbeispiele sind in Zeichnungen dargestellt und werden im folgenden näher erläutert.Exemplary embodiments are shown in drawings and are explained in more detail below.

Nach Fig. 1 ist in einer Klemmenplatte 1 ein Anschlußbolzen 2 eingelassen. Sein Schaft 21 ist von dem hohlzylindrischen Teil 31 eines Klemmenstücks 3 umgeben. Der Anschlußbolzen dient der Verbindung eines Netzleiters 4 (nicht dargestellt) mit einer Wicklungsableitung 5 und stellt mittels einer Klemmenverbindung 6 die Verbindung zu einem weiteren Anschlußbolzen her. Das Klemmenstück besitzt einen Ansatz 32, der senkrecht zur Achse des hohlzylindrischen Teils mit diesem einstückig verbunden ist. Im äußeren Bereich des Ansatzes ist eine Gewindebohrung 33 eingebracht, deren Achse parallel zur Achse des hohlzylindrischen Teils verläuft. Um diese Bohrung wird bei kabelschuhlosem Anschluß des Netzleiters das blanke Ende des Netzleiters in Schlaufenform gelegt, und anschließend mit einem Klemmbügel 35 unter Zuhilfenahme einer Schraube 34 festgesetzt, für die die Gewindebohrung 33 vorgesehen ist. Die Wicklungsableitung 5 ist mit einem Kabelschuh 51 abgeschlossen, der direkt mit dem Anschlußbolzen verbunden wird. Ein Verdrehungsschutz für den Netzleiter ist hier nicht erforderlich. Nach dem Anschluß des Netzleiters, der Wicklungsableitung und der Vornahme der Klemmenverbindung erfolgt das Festsetzen durch eine Mutter 22, die auf das freie Ende des Anschlußbolzens aufgeschraubt wird. Für den Verdrehungsschutz der Wicklungsableitung 5 mit dem Kabelschuh 51 ist in der Klemmenplatte 1 eine Nut 11 vorgesehen, deren Breite auf die Breite des Kabelschuhs abgestimmt ist. Die Länge dieser Nut wird durch den Anschlußbereich des Kabelschuhs bestimmt.According to Fig. 1, a connection pin 2 is inserted in a terminal plate 1. Its shaft 21 is surrounded by the hollow cylindrical part 31 of a clamp piece 3. The connecting bolt is used to connect a network conductor 4 (not shown) to a winding lead 5 and uses a terminal connection 6 to connect to a further connecting bolt. The clamp piece has an extension 32 which is connected to the hollow cylindrical part in one piece perpendicular to the axis of the latter. In the outer area of the approach, a threaded bore 33 is made, the axis of which is parallel to the axis of the hollow cylindrical Partly runs. The bare end of the power conductor is placed in a loop shape around this hole when the power conductor is connected without a cable lug, and then fixed with a clamping bracket 35 with the aid of a screw 34, for which the threaded hole 33 is provided. The winding lead 5 is terminated with a cable lug 51 which is connected directly to the connecting bolt. Protection against twisting for the mains conductor is not necessary here. After the connection of the mains conductor, the winding derivation and the making of the terminal connection, the fixing is carried out by a nut 22 which is screwed onto the free end of the connecting bolt. For the protection against twisting of the winding lead 5 with the cable lug 51, a groove 11 is provided in the terminal plate 1, the width of which is matched to the width of the cable lug. The length of this groove is determined by the connection area of the cable lug.

Nach Fig. 2 kann der Netzleiter mit einem Kabelschuh 41 direkt am Anschlußbolzen 2 befestigt werden. In diesem Fall übernehmen die Nocken 36 den Schutz gegen Verdrehen.According to FIG. 2, the mains conductor can be attached directly to the connecting bolt 2 with a cable lug 41. In this case, the cams 36 provide protection against twisting.

Die Figuren 3 und 4 unterscheiden sich von den Figuren 1 und 2 lediglich durch den Einsatz einer Lasche 35', wozu zwei Schrauben 34 benötigt werden, um den blanken Netzleiter festzusetzen. Bei den Nocken 37 handelt es sich um eine an die Formgebung des Klemmenstücks 3 angepaßte Nockengestaltung mit dreieckigem Querschnitt.Figures 3 and 4 differ from Figures 1 and 2 only by the use of a tab 35 ', for which two screws 34 are required to fix the bare network conductor. The cams 37 are cams with a triangular cross section which are adapted to the shape of the clamp piece 3.

Nach Fig. 5 bis 7 sind beim Klemmenstück 3 Nocken 36 mit rechteckigem Querschnitt vorgesehen, nach den Fig. 8 bis 11 Nocken 37 mit dreieckigem Querschnitt.According to FIGS. 5 to 7, 3 cams 36 with a rectangular cross section are provided in the terminal piece, according to FIGS. 8 to 11 cams 37 with a triangular cross section.

Nach Fig. 12 und 13 ist eine bevorzugte Ausführungsform der Klemmenplatte 1 mit 6 Anschlußbolzen 2 bestückt. Die Anschlußbolzen sind mit ihrem Schaft 21 in die Klemmenplatte eingelassen. Der Bereich der Anschlußbolzen ist mit Nuten versehen, die von außen für den Kabelschuh der Wicklungsableitung (nicht dargestellt) als Verdrehungsschutz dienen. Die Klemmenplatte ist mit Klemmenstücken 3 vollständig dargestellt. Die Anschlußbolzen einer Anschlußseite können mit den Anschlußbolzen der anderen Seite durch die Klemmenverbindungen 6 verbunden werden. Eine derartig bestückte Klemmenplatte kann mit Hilfe von Befestigungsbolzen 7 mit dem elektrischen Gerät verbunden werden.12 and 13, a preferred embodiment of the terminal plate 1 is equipped with 6 connecting bolts 2. The connecting bolts are inserted with their shaft 21 into the terminal plate. The area of the connecting bolts is provided with grooves that serve from the outside for the cable lug of the winding lead (not shown) as protection against rotation. The terminal plate is shown completely with terminal pieces 3. The connection bolts on one connection side can be connected to the connection bolts on the other side by the terminal connections 6. A terminal plate equipped in this way can be connected to the electrical device with the aid of fastening bolts 7.

In Fig. 14 und 15 ist die bevorzugte Ausführungsform der Klemmenplatte 1 für mittlere Leiterquerschnitte dargestellt, wozu statt der Klemmbügel Laschen 35' zum Einsatz kommen.14 and 15 show the preferred embodiment of the terminal plate 1 for medium conductor cross-sections, for which purpose tabs 35 'are used instead of the clamping bracket.
