Description
Elektrische Anschlußschiene für Schaltgeräte Electrical connection rail for switchgear
Die Erfindung betrifft eine elektrische Anschlußschiene zwischen
Anschlußpunkt und. Leistungskontakt für Schaltgeräte mit einem
Isolierstoffsockel, insbesondere Schütze.The invention relates to an electrical connection rail between the connection point and. Power contact for switching devices with a
Insulating bases, in particular contactors.
Die verbesserte Formgebung der Anschlußschiene vermindert wesentlich ihre Herstellungskosten.The improved shape of the connecting rail significantly reduces their manufacturing costs.
j Bei den bekannten Schaltgeräten besteht die Anschlußschiene aus; j In the known switching devices, the connecting rail consists of;
Flachkupfer und benötigt besondere Befestigungsmittel. In man- i chen Fällen ist sie zugleich auch als festes Schaltstück oder j Schaltstückträger ausgebildet, wobei unter Umständen die An- ; schlußschiene gebogen .ist. Der rechteckige Querschnitt des Vollprofils ist in mehrfacher Hinsicht von Nachteil:Flat copper and requires special fasteners. In man- i In some cases it can also be used as a fixed contact or j Contact piece carrier formed, where under certain circumstances the connection; tail rail is curved. The rectangular cross-section of the full profile is disadvantageous in several ways:
Einmal ist das Verhältnis von Volumen zur Oberfläche der Anschlußschiene, welches für die Abführung der Stromwärme wesentlich ist, ungünstig.On the one hand, the ratio of volume to the surface of the connecting rail, which is essential for the dissipation of the electricity heat, unfavorable.
Zum anderen ist die mechanische Steifigkeit - das Widerstandsmoment - relativ gering, was bei einer gebogenen Anschlußschiene zur Erreichung einer genügenden Stabilität zu erhöhtem Aufwand an Leitermaterial führt.On the other hand, the mechanical rigidity - the moment of resistance - is relatively low, which is the case with a curved connecting rail to achieve sufficient stability leads to increased expenditure on conductor material.
Aufgabe der Erfindung ist es, durch ein günstiges Profil die j Oberfläche der Anschlußschiene bei gleichem Querschnitt zu vergrößern, um eine optimale Wärmeabgabe zu erreichen, und gleich-: zeitig die anderen vorgenannten Nachteile zu vermeiden. ' The object of the invention is to use a favorable profile to enlarge the surface of the connecting rail with the same cross section in order to achieve optimal heat dissipation and at the same time to avoid the other aforementioned disadvantages. '
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Anschlußschiene als U-Profil ausgebildet ist, deren beide Schenkel in entsprechende Nuten des Isolie rstoffsockels eingelassen sind.This object is achieved according to the invention in that the connecting rail is designed as a U-profile, the two legs of which are embedded in corresponding grooves of the Isolie rstoffsockels.
Eine weitere vorteilhafte Ausgestaltung der Neuerung ist, daß die Luftspalte zwischen Anschlußschiene und Isolierstoffsockel vergossen sind.Another advantageous embodiment of the innovation is that the air gap between the connecting rail and the insulating material base are shed.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch eine günstige Profilgebung der Anschlußschiene, hinsichtlich der Abführung von Stromwärme, eine Verringerung des Querschnitts ermöglicht wird. Das hat eine bedeutende Ersparnis elektrischen Leitermaterial zur Folge, oder was dasselbe ist, die Anschlußschiene kann bei gleichem Querschnitt einen entsprechend höheren Strom führen.The advantages achieved by the invention are in particular that, through a favorable profile of the connecting rail, with regard to the dissipation of electricity, a reduction in Cross-section is made possible. This results in a significant saving of electrical conductor material, or what is the same, the connecting rail can carry a correspondingly higher current with the same cross-section.
Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the innovation is shown in the drawing and is described in more detail below. It shows
Fig. 1 die Einbettung der Anschlußschiene in den Isolierstoffsockel, Fig. 1 the embedding of the connecting rail in the insulating material base,
Fig. 2 die Befestigung der Anschlußschiene im IsolierstoffsockelFig. 2 shows the attachment of the connecting rail in the insulating material base
Die elektrische Anschlußschiene 1 besteht aus einem U-Profil und ist zur Herstellung eines verbesserten V/ärmekontaktes mit ihren beiden Schenkeln passend in die Nuten des Isolierkörpers 2 eingelassen. The electrical connection rail 1 consists of a U-profile and is inserted into the grooves of the insulating body 2 with its two legs to create an improved V / arm contact.
Eventuelle Luftspalte ? können, da Luft eine sehr schlechte Wärmeleitfähigkeit besitzt, mit Lack ausgefüllt werden.Any air gaps? because air has a very poor thermal conductivity has to be filled with varnish.
Die Schraube 4 dient als Anschlußbefestigung. Die Anschlußschiene 1 wird an bestimmten Stellen 5 durch Umbiegen eines Schenkelendstückes 6 mit dem Isoljerkörper 2 verklammert.The screw 4 serves as a connection attachment. The connecting rail 1 is at certain points 5 by bending a leg end piece 6 clamped to the insulating body 2.
