Description
Die bekannten AbzweigMemnien für die
Befestigung der Steig- und Abzweigleitungen bestehen in der Regel aus Schraubenschlitzklemmen,
welche aber wegen des nur teilweise eingeschnittenen Gewindes zu Anständen Anlaß
geben. Andere Anordnungen haben den Nachteil, daß die Gefahr des Abquetschens der Leitung in hohem Maße vorhanden ist.
Bei der Klemme nach der Erfindung wirdThe known AbzweigMemnien for the attachment of the riser and branch lines usually consist of screw slot clamps, which give rise to adversities because of the only partially cut thread. Other arrangements have the disadvantage that there is a high risk of the line being pinched off.
When the clamp according to the invention
ίο eine sichere Befestigung und ein guter Kontakt bei einfachster Handhabung erreicht. Die Fig. ι und 2 stellen die vollständige Abzweigung für eine dreipolige Abzweigung dar, und zwar sind darin d1 die Steigleitungen, d2 die Abzweigleitungen und b die drei Abzweigklemmen, i ist die Isolierstoffgrundplatte, welche mit entsprechenden Rillen für die Aufnahme der Leitungen und mit Vorsprüngen zum Schütze gegen einen Kurz-Schluß beim Aufsetzen der Kappe versehen ist. Die Klemmen sind in bekannter Weise auf der Platte i durch Aufschrauben oder durch Einkitten befestigt. Eine einzelne Klemme ist in drei Ansichten in den Fig. 3, 4 und 5 dargestellt, und es ist daraus zu ersehen, daß das Klemmgehäuse aus zwei Teilen besteht, einem Unterteil α und einem darübergeschobenen Oberteil b. Der Oberteil b trägt die drei Druckschrauben c1, c2 und cs, von denen die mittlere Schraube c2 für die Anpressung der in der Nut e des Unterteiles a liegenden Steigleitung d1 dient. Der Oberteil b wird senkrecht zu dem Steigleitungsdraht, also in der Richtung der Abzweiglei- tungencP aufgeschoben, bevor die Schrauber2 heruntergedreht ist. Die Aussparung in dem Unterteil α bei / und die entsprechende Aussparung im Oberteil b dienen zur Aufnahme der Abzweigleitungen d2, welche nach rechts und links gehen und durch die Schrauben c1 und cz angepreßt werden. Um den Druck der Schrauben auf die Leitungsdrähte besser zu verteilen, können zwei Preßplatten übergeschoben werden, von welchen die eine, wie Fig. 5 in h erkennen läßt, eine doppel-T-förmige Gestalt hat und die zweite in dem Oberteil b liegende, mit g bezeichnete Platte in der Mitte ein Loch für den Durchlaß der Schraube c2 besitzt und dadurch gleichzeitig unverlierbar ist.ίο a secure attachment and a good contact achieved with the simplest handling. Figs. Ι and 2 represent the complete junction for a three-pole junction, namely therein d 1 the risers, d 2 the branch lines and b the three branch terminals, i is the insulating base plate, which with corresponding grooves for receiving the lines and is provided with projections to protect against a short circuit when putting on the cap. The clamps are fastened in a known manner on the plate i by screwing or cementing. A single clamp is shown in three views in FIGS. 3, 4 and 5, and it can be seen therefrom that the clamp housing consists of two parts, a lower part α and an upper part b pushed over it. The upper part b carries the three pressure screws c 1 , c 2 and c s , of which the middle screw c 2 is used to press the riser d 1 lying in the groove e of the lower part a . The upper part b is pushed on perpendicular to the riser wire, that is to say in the direction of the branch lines CP, before the screwdriver 2 is turned down. The recess in the lower part α at / and the corresponding recess in the upper part b serve to accommodate the branch lines d 2 , which go to the right and left and are pressed by the screws c 1 and c z. In order to distribute the pressure of the screws on the lead wires better, two press plates can be pushed, by which the leaves a, as shown in FIG. 5 seen in h, has a double-T-shape and the second b in the upper part located, with g plate has a hole in the middle for the passage of the screw c 2 and is therefore captive at the same time.
Trotzdem die Klemme aus zwei Teilen besteht, sind nicht mehr Schrauben notwendig, als für die Kontaktgebung normal erforderlich sind. Even though the clamp consists of two parts, no more screws are necessary. than are normally required for contacting.
Wenn man den Stromweg verfolgt, so sieht man, daß dieser von der Steigleitung d1 über das einzige Kontaktstück α auf die Leitungen d- geht. Es gibt also wenig Ubergangswiderstände, und der Zusammenbau der Klemme ist sehr einfach. Ferner ist jederzeit eine leichte Prüfung und Lösung der Leitungen möglich.If you follow the current path, you can see that it goes from the riser d 1 via the single contact piece α to the lines d-. So there is little contact resistance and the assembly of the clamp is very easy. Furthermore, the lines can be easily checked and removed at any time.
