Claims (1)

ι 2 that it is easier to assemble compared to the known terminals ... - ». "^ Patent claims: The given task is thereby achieved with a branch terminal of the type mentioned at the beginning 1. Branch clamp for busbars elek- 5 solves that the clamping parts are the legs of the same. the clamping parts, characterized by the fact that the clamping parts have projections and recesses in the manner of projections and recesses. of the same, for clamping the collector io zen that a recess of one clamp is a rail (1) serving clamps (3, 4), the projection of which is assigned to the other clamp.
The projections can be formed in such a way that the hammer heads of the counter-clamp would have a recess (6 or 7) who have 15 detes profile. a scolding (3 or 4) a protrusion The protrusions and recesses can (4 or 5) of the other clamp (4 or 3) also be dovetail-shaped, is ordered. To facilitate assembly, the branch can with 2. Branch terminal according to claim 1, characterized in that the through-thread for receiving the clamp is provided in that the projections (4, S) are provided with screws. The object of the invention is shown in the drawing Recesses (6, 7) shows a for receiving the urine, for example and purely schematically shown Hs mcrköpfe (4, 5) of the counter clamp designed
Profile best. F i g. 1 a side view, 3. Branch terminal according to claim 1, characterized in that Fig. 2 is a plan view according to FIG. 1.
characterized in that the recesses (6, 7) are designed to branch off a current path from one and projections (4, 5) dovetail-shaped busbar 1 to a branch 2, two are formed. identically designed clamps 3, 4 are used. Whose 4. Branch terminal according to claim 1 to 3, that legs are arranged on both sides of the branch 2, characterized in that the branch (2) with 30 your arc include the busbar 1. The En-Durchgangsgewindc / to take up the clamping ends of the arches point to the form-fitting, Zugauf screws (8, 9) is provided. intermeshing in the manner of tabs 4.5 and recesses 6.7 that a recess 6 or 7 of a clamp 3 or 4 35 a projection 4 or 5 of the other clamp 4 or 3 is assigned. In the illustration (FIG. 2) the projections 4, 5 are designed like a hammer head, while the recesses 6, 7 a to accommodate the hammer heads The invention relates to a junction clamp for 40 4. 5 of the counter clamp have a formed profile.
Busbars for electrical switchgear with the projections 4.5 and recesses 6.7 Clamping of the branch serving, clamping can also be dovetail-shaped, d. H. in screw-bearing clamping parts. V-shape. In a known branch terminal, a For mounting the branch according to the invention Clamping part is the other and forms together with at 45 clamp a clamp is screwed by means of screws 8, 9 at its protruding end Klemmbak- the branch 2, which for this purpose ken a clamping for the round cross-section is provided with through-tapped holes. So-waveguide, which is arranged transversely to the axis of the cross-section then the counter clamp on the branch 2 also round branch (German places and fastened with nuts 10, 11.
Patent 1 060001). 50 The clamps 3, 4 are designed so that they with The well-known branch terminal is suitable for the highest voltages thanks to its shape which results in sufficient contact pressure, since for voltage it encompasses the busbar 1,
a favorable field distribution is designed. Disadvantageous compared to the known junction is the is their relatively expensive production, the reason for which is the branch according to the invention, apart from the large number of individual parts required for fastening screws, only from two identical parts, which are small that have to be machined by punching and bending,
and are difficult to assemble. A simple assembly is given that The invention is based on the object of having a clamp screwed to the branch-branch terminal to create, which can with the most favorable fields, thus free hand for attaching the distribution, apart from clamping screws, only consists of 60 counter clamps. By that largely consists of two identical parts, which without complex interlocking interlocking of the clamp ends Machining should be producible. The invention provides a good distribution of tension or tension The appropriate branch terminal should also be designed in such a way that the entire width of the clamp is achieved.
