Description

Schraubenkleinme für Abzweigdoser, Um Kurzschlüsse durch Cberspringen von I Funken von einer zur anderen KI2minstelle g m zu vermeiden, hat man bei Abzi#,-ei-dos,-bereits den Dosendeckel mit die Klemnist#2lIcn gegenseitig isoliercnden Trennwänden verschien und die zum Festklemmen der Leitungen dienenden Schrauben senkrecht zum Dosenboden angeordnet. Die Erfindung, be- trifft eine Verbessertin-- dieser Klemmschrauben und besteht dariti, daß die Schraubcnköpfe seitUch ab#c111acht und verbreitert sowie b im Zuge dieser Abilachung geschlitzt sind. Dadurch wird der Vorteil erzielt, daß infolge des Vorhandenseins der Trennwände- im Dosendeckel. die -flachen Schraubenköpfe über das Maß des Schraubendurcbmessers hinaus verbreitert werden können, so daß sie bequem von Hand ein-eführt werden können, um nach erfolgtem Einführen vermittels eines Scliraubenzichers festigezogen zu werden. Man ist I also in der Lage, beim Festklemmen der Lcitungen die Schrauben ganz herausschrauben I zu können, um ein leichtes Einführen der Leitun-en in die Klicii-imstellen zuermö-lichen. und ist nicht niulir -ezwungen, wie bisher, dic Schrauben nur zu lockern, da man sie nicht mehr mühselig mit einem Schraubenzieher wieder einzuführen braucht, sondern bequem von Hand wieder einschrauben kann.Schraubenkleinme for Abzweigdoser, to avoid short circuits due Cberspringen of I sparks from a g for other KI2minstelle m, has one at Abzi #, - verschien mutually isoliercnden partitions ei-dos, -bereits the can lid with the Klemnist # 2lIcn and the for clamping Cables serving screws arranged perpendicular to the bottom of the can. The invention sawn makes a Verbessertin-- of each collar and consists dariti that the Schraubcnköpfe seitUch from # c111acht and widened and b in the course of this Abilachung are slotted. This has the advantage that due to the presence of the partition walls in the can lid. the flat screw heads can be widened beyond the size of the screw diameter, so that they can be easily inserted by hand in order to be tightened after insertion by means of a screw lock. So you are able to fully unscrew the screws when clamping the cables so that the cables can be easily inserted into the click points. and it is not necessary, as before, to just loosen the screws, since they no longer have to be laboriously reinserted with a screwdriver, but can easily be screwed in again by hand.

Auf der Zeichnung sind die neuen Klemmschrauben an einer Alin#-eil-dose gezeigt, wabei Abb. i die Dose in Stirnansicht, Abb. 2 den 1)os(:#iideelzel im Innern, Abb. den Dosenboden in Seitenansicht und Abb. eine Draufsicht auf den Dosenboden mit im Schnitt dargestellten Trennwänden des Deckels veranschaulicht.The drawing shows the new clamping screws on an Alin # -eil-can, where Fig. I the can in front view, Fig. 2 the 1) os (: # iideelzel inside, Fig. The bottom of the can in side view and Fig Illustrated top view of the can bottom with partitions of the lid shown in section.

Mit i sind die beispielsweise diagonal verlaufenden Trennwände des Dosendeck-,els bczeichnet, deren Wandstärke bei 2 derart geschwächt ist, daß je nach Zahl und Stärke der festzukleinmenden Leitungen Durchlässe aus-Z> gebrochen werden können. Durch die Anö rdnung dieser Trennwände i in Verbindung mit einer inneren Ringwand werden (vgl. Abb. 1 für die Dosenbefestigungsklemme 4 und die X]cirmischrauben je eine Kammer -gebildet. Die Sehr, aubenköpfe 5 sind erfin dungsgemäß verbreitert und seitlichabgeflacht und weisen im Zuge di-es,cr Abflachung Schlitze auf.The diagonal partition walls of the can lid, els bc, are marked with i, the wall thickness of which is weakened at 2 in such a way that, depending on the number and thickness of the lines to be fixed, passages can be broken out. By Anoe these partitions rdnung i in conjunction with an inner annular wall (cf., Fig. 1 for the doses fixing clip 4 and the X] per cirmischrauben a chamber -gebildet. The Very aubenköpfe 5 OF INVENTION are widened dung according to and seitlichabgeflacht and have in the course di-es, cr flattening slits on.
