Es sind bereits Schraubenschlitzklemmen mit gekreuzten Schlitzen aus rundem Profil sowie solche aus Vierkantprofil bekannt. Bei den aus rundem Profil hergestellten Schlitzklemmen werden die freistehenden, durch die Schlitze gebildeten Zapfen des Profils beim Einsetzen und Anziehen der die Drähte festklemmenden Madenschraube auseinandergepreßt. Dieses Auseinanderpressen wird jedoch durch Aufsetzen eines Überwurf ringes verhindert. In gleicher Weise wird bei den Vie'rkantprofuklemmeri das Auseinanderstreben der Zapfen durch 'einen viereckigen Überwurfring vermieden. Diese viereckigen Spannringe besitzen jedoch den Nachteil, daß dieselben beim Ziehen vielfach ■ mißlingen und daß die Kanten und Ecken beim Gebrauch leicht brüchig werden, so daß sie in ihrer Haltbarkeit und Widerstandsfähigkeit erheblich geschwächt werden. Andererseits bietet aber das Vierkantprofil 'eine wesentlich größere Ausnutzungsmöglichkeit seines Querschnitts, so daß das Vierkantprofil bevorzugt würde, wenn nicht die Herstellung solcher viereckiger Spannringe solche Schwierigkeiten verursachen würde.There are already screw slot terminals with crossed slots made of a round profile as well as those known from square profile. With the slot clamps made from a round profile become the free-standing tenons of the profile formed by the slots when inserting and tightening the ones that clamp the wires Grub screw pressed apart. This pressing apart will, however prevented by putting on a union ring. In the same way with the Vie'rkantprofuklemmeri the diverging of the tenons through a square union ring avoided. However, these square clamping rings have the disadvantage that the same often fail when pulling and that the edges and corners easily when in use become brittle, so that their durability and resistance are considerably weakened will. On the other hand, however, the square profile offers a much greater possibility of utilization its cross-section, so that the square profile would be preferred, if not the manufacture of such square ones Clamping rings would cause such difficulties.
Die Erfindung behebt diese Mängel dadurch, daß das obere Ende der Vierkantschlitzklemme als ein nach innen abgesetzter Rundzapfen zum Aufsetzen eines runden Spannringes ausgebildet ist.The invention overcomes these deficiencies in that the upper end of the square slot clamp as an inwardly offset round tenon to put on a round one Tension ring is formed.
Eine "derartige Vierkantschlitzklemme ist in den Abb. 1 bis 3 der Zeichnung beispielsweise dargestellt, und zwar zeigt Abb. 1 die Einzelteile der Schlitzklemme teils in Seitenansieht, teils im lotrechten Schnitt, die Abb. 2 die zusammengesetzte Vierkantschlitzklemme in Seitenansicht, während die Abb. 3 die Draufsicht auf die Abb. 2 wiedergibt.Such a square slot clamp is shown in Figs. 1 to 3 of the drawing, for example shown, namely Fig. 1 shows the individual parts of the slot clamp partly in side view, partly in vertical section, Fig. 2 shows the assembled square slot clamp in side view, while Fig. 3 shows the plan view of Fig. 2.
Wie daraus zu ersehen ist, ist das obere Ende des vierkantigen Fußstückes α als Rundzapfen b zum Aufsetzen des runden Spannringes c ausgebildet. Die Madenschraube d wird in bekannter Weise in das Gewinde / eingeschraubt, um dadurch die in die Schlitzen eingeführten Leitungsdrähte festzuklemmen.As can be seen from this, the upper end of the square foot piece α is designed as a round pin b for placing the round clamping ring c . The grub screw d is screwed into the thread / in a known manner in order to clamp the lead wires inserted into the slots.
