The invention relates to a cable branch terminal for sector and round conductors with two through at least one clamping screw held together clamping jaws, one of which for the Sector ladder with one in cross-section circular arc-shaped groove and the other with one in cross-section angular groove is provided with inclined clamping surfaces. With the known cable branch terminals of this type, the angular groove has either an angle of 90 ° or an angle of 120 ° so that either a sector leader with a sector wire of 90 ° or a sector leader with a Sector angle of 120 ° can be clamped. For every sector leader with a different sector angle a corresponding cable branch terminal must therefore be provided. This will on the one hand warehousing and, on the other hand, assembly are made more difficult and expensive.

The invention is based on the object of the known branch terminals of the type referred to above to improve and train them so that with one and the same branch terminal optionally sector conductor with different sector angle, e.g. B. of 90 ° or 120 °, can be clamped. The solution to this problem takes place according to the invention in that in the angular groove of the corresponding clamping jaw several pairs of inclined surfaces with different angles for optional clamping of Sector ladders with different sector angles are provided. With the branch terminal according to the invention So different sector conductors with different sector angles can be clamped. This on the one hand the storage and on the other hand the assembly is simplified and cheaper.

The part of the clamping jaw which has the several pairs of inclined surfaces can either be integral with this jaw or designed as an insert and in a corresponding recess of the Be used clamping jaws. It is possible to use the recess in the clamping jaw for to form the insert as an angular groove for clamping a sector conductor, its Sector angle differs from the sector angles of those sector conductors that are used in the insert, the has one or more pairs of inclined surfaces, can be clamped. Insert pieces for jaws of Cable branch terminals are known per se (German utility model 1 795 759). Here are the both jaws made of aluminum. On one side of the clamping screw are in the two Baking grooves for an aluminum conductor and on the other side grooves for a copper conductor in front of the cable branch terminal for sector and round conductors

seen. To adapt to the material of the copper conductor, the associated grooves are provided with shell-shaped, Equipped with copper inserts having the same thickness.

In order to be able to clamp sector conductors with a sector angle of 180 °, the outermost one is on the side Inclined clamping surface pair a horizontal pair of clamping surfaces for clamping such a Sector head provided with a sector angle of 180 °. For better holding of the sector ladder are the cross-section angular groove or the inclined surfaces in a manner known per se with longitudinal grooves Mistake.

An exemplary embodiment of the invention is shown in the figures. It shows

F i g. 1 shows a section through a cable branch terminal according to the invention,

F i g. 2 is a view from the left according to FIG. 2 and

F i g. 3 shows a side view of the two clamping jaws of the cable branch clamp according to FIGS. 1 and 2 in enlarged scale.

The cable branch terminal shown consists of the two clamping jaws 1 and 2 and a clamping screw 3 that holds the two clamping jaws 1 and 2 together. For the branch conductor 4 , the two clamping jaws 1 and 2 have grooves 5 and 6 that are circular arc-shaped in cross section. On the other side of the clamping screw 3 according to FIG. 1, the clamping jaw 1 has a groove 7 with a circular arc in cross section and the other clamping jaw 2 has a groove 8 which is delimited by inclined surfaces 9, 10 and 11, 12. As can be seen in particular from FIG. 3, the inclined surfaces 9, 10 form an angle of 90 ° and the inclined surfaces 11, 12 form an angle of 120 °. The sector conductor 13 shown has a sector angle of 90 °. With its two surfaces delimiting the sector angle, it is supported on inclined surfaces 9 and 10

away. If a sector conductor is placed in the groove 8 with a sector angle of 120 °, then this is supported with its two surfaces delimiting the sector angle on the inclined surfaces 11 and 12 of the groove 8. For better holding of the sector conductor 13 or the branch conductor 4, the grooves 5 to 8 have longitudinal ribs 14, which also contribute to improving the contact. Above and on both sides of the inclined surfaces 11, 12, a horizontal support surface for a sector conductor with a sector angle of 180 ° can be provided. From FIGS. 1 and 3 it can be seen that the clamping jaw 2 is also formed in one piece in the region of the inclined surfaces 9 to 12. There is of course also the possibility of producing the part of the clamping jaw having the inclined surfaces 9 to 12 as an insert and providing the clamping jaw 2 with a corresponding recess into which this part having the inclined surfaces 9 to 12 is inserted. The recess provided for this can also be designed as a groove with a pair of inclined surfaces for clamping a sector conductor, the sector angle of which differs from the sector angles of those sector conductors that can be clamped in the groove of the corresponding insert. As the F i g. 1 and 3 further show, a conically widened recess 15 is provided in the clamping jaw 1, through which the screw 3 engages with a relatively large amount of play. As a result of this recess 15, it is possible to clamp branch conductors 4 or sector conductors 13 with substantially different cross-sections between the clamping jaws 1 and 2. The clamping jaw 9 has a thread 16 for the clamping screw 3. Patent claims: 1.
