PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft ein Geräth für Verbindung und Abzweigung elektrischer sogenannter concentrischer Kabelleitungen, welches im Wesentlichen aus drei in bestimmter gegenseitiger Stellung vereinigten Schraubstöcken besteht, wodurch es ermöglicht wird, die Kabeltheile in der gehörigen, dem T-Anschlufs oder dem Ueberkreuzungsanschlufs entsprechenden Lage während der Herstellung der Verbindung zu halten, bis dieselbe infolge Einschliefsens der Theile in einem hierzu geeigneten Gehäuse vollendet ist. Das Verfahren der Verbindung selbst .beruht auf der vortheilhaft mittelst einer besonderen Einschneidzange erzielten Blofslegung der äufseren und inneren Kabelleitung, ferner auf der Spleifsung und Verlöthung der inneren Leitungen, Bedeckung derselben mit Isolirstoff und der elektrischen Verbindung der äufseren Leitungen mit Hülfe von zweitheiligen, geeignet gestalteten metallenen Gehäuseschalen bezw. Verbindungsröhren, an welchen die Kabeldrähte zu verlöthen sind.The present invention relates to a device for connecting and tapping electrical devices so-called concentric cable lines, which essentially consist of three in certain mutual position of united vices, which makes it possible the cable parts in the appropriate one, corresponding to the T connection or the crossover connection To be kept in position during the establishment of the connection, until it has been enclosed in a suitable one as a result of the inclusion of the parts Housing is completed. The method of connection itself is based on the beneficial Exposure of the external and internal ones achieved by means of special cutting pliers Cable line, also on the splicing and soldering of the inner lines, covering the same with insulating material and the electrical connection of the outer lines with help of two-part, suitably designed metal housing shells respectively. Connecting tubes which the cable wires are to be soldered.

Die Gebrauchsanwendung des in Fig. 7 und 8 dargestellten Hilfsgeräths gemäfs der Erfindung bezieht sich auf die Verbindung und Abzweigung eines Kabels nach Fig. 1 und 2. An demselben ist mit a die innere mehrdrähtige Seele und mit c die äufsere, aus concentrisch angeordneten Drähten bestehende Leitung bezeichnet ; letztere ist von ersterer durch die Isolirschicht b getrennt und aufsen mit der Isolirschicht d umhüllt, auf welcher noch eine metallene Schutzdecke e angebracht sein kann. Zur Verbindung bezw. Leitungsabzweigung mufs die äufsere Leitung c und die innere Leitung a, ungefähr so, wie in Fig. 2 dargestellt ist, durch Fortnahme der anderen Schichten bloßgelegt werden. Dies kann mit Hilfe einer Einschneidzange geschehen.The application of the auxiliary device shown in Fig. 7 and 8 according to the invention relates to the connection and branching of a cable according to Fig. 1 and 2. On the same is with a the inner multi-wire core and with c the outer, consisting of concentrically arranged wires Line denotes; the latter is separated from the former by the insulating layer b and encased on the outside with the insulating layer d , on which a metal protective cover e can also be attached. To connect respectively. Branch lines, the outer line c and the inner line a, approximately as shown in Fig. 2, are exposed by removing the other layers. This can be done with the help of cutting pliers.

Um für den Werkzeuggebrauch und die sonstige Behandlung eine, sichere Auflagerung der zu verbindenden Kabel zu ermöglichen, wird der dreifache Schraubstock (Fig. 7 und 8) in Anwendung gebracht. Dieses Geräth besteht aus einem, die drei Schraubstöcke 4BC tragenden Tisch, der mit einem Pfosten oder Schaft E versehen ist, welcher innerhalb eines mit der Fufsplatte G versehenen Ständerrohres verstellbar ist, um die Höhenlage des Tisches D veränderbar zu machen. Die Maulöffnungen der gegenüberliegenden Schrauhstöcke A und C sollen in derselben Achse liegen und die Achse der Maulöffhung des dritten,- in gleichem Abstand von der Tischmitte angeordneten Schraub-The triple vice (FIGS. 7 and 8) is used to enable the cables to be connected to be securely supported when using tools and other handling. This device consists of a table carrying the three vices 4BC, which is provided with a post or shaft E , which is adjustable within a stand tube provided with the base plate G in order to make the height of the table D changeable. The mouth openings of the opposite vices A and C should lie in the same axis and the axis of the mouth opening of the third screw - at the same distance from the center of the table

Claims

Stick B should be directed perpendicular to that axis (Fig. 8).

If z. B. If an ordinary T-shaped connection is to be made, the continuous cable is fastened in claws A and C , while the branching cable is clamped in B. With the aid of the above-mentioned pliers, various cuts are made into the insulation of the main cable, in order to free it from the insulation; The unilateral exposure of the vice device allows easy handling of the cutting pliers.

Then the connection between the 'conductive central wires α of the main cable, which is held in a stretched position by A and C , and the branching cable, which is fixed in B , is established. The connection is made in the usual way by braiding and soldering the individual lead wires. Now the insulating layer b is restored by placing a non-conductive tape around the conductive core wires to the required thickness.

Then a pair of T-pipe shells (Fig. 5) are attached to the insulating layer b. The T-tubes and the other tubes of different shapes for different connections (according to FIGS. 3 and 4) are preferably to be punched or pressed from thin metal sheet which is covered with a layer of tin, in order to facilitate the adhesion of the soldering tin. After these tubes have been pushed onto and around the insulation b that has been put in place, the individual wire groups c of the cables stored in the vices A, B and C are bent over the aforementioned tubes, fastened with binding wire and then the whole thing is soldered or curled together finally covered with rubber strips or insulating canvas.

While the three members of the T-connector are still held in position by the vices A, B and C, an internally turned (grooved) rosette or bushing, as shown in FIG. 6, is made of wood or other insulating material over the connection , the links in question going through the grooves ff ¹ / ″ .

A disk ρ made of paper or the like is then attached to the open base of the wooden rosette. The recess is then filled in liquid form through a hole cut in the cover with earth resin or some other insulating medium. When the connecting piece is freed of any used retaining wires, it is ready to be laid at its point of use.

Patenτ claim:

Auxiliary device for the connection and branching of cables, consisting of a support plate (D) which can be adjusted in height by means of extendable stand fukes (EF) , on which two conaxial vices (A and C) and a third vise (B) at right angles to the Purposes are appropriate so that the cables to be combined for the T-connection can be clamped in it and held in position during the necessary measures.
