This results in a sleeve-like connection two conductor rods 1.
- the cylinder segments In order to ensure that the two conductor bars do not come into electrical contact with one another, the cylinder segments have a segment angle which is less than 180° so that after attachment to the conductor bars the segments do not touch but a gap is left. Due to the blind threaded holes, it is also not possible for an electrical connection to be made between the conductors via the screws.
- Fig. 7b shows a connecting device for an angled connection.
- the angle is 90° in the illustrated embodiment.
- the angles of the two angle elements 75 and 75 on both legs again have the cylinder segment shape and the screw holes 77, 78, as have already been described with reference to the embodiment shown in FIG. 7a.
- the conductor rods 1 to be connected can be mitred. All that is required, however, is that the ends of the current conductor rods 1 to be connected as far as possible into the
- FIG. 7c also shows a right-angled connecting device with connecting elements 79 and 80.
- the connection of the conductor rods 1 takes place in the same way as in the connecting devices shown in FIGS. 7a and 7 and described in connection therewith.
- the connecting device shown in FIG. 7c is required in addition to the connecting device shown in FIG. 7b if a connection of the current conductor rods is desired in a direction pointing out of the plane spanned by the legs of the connecting device shown in FIG. 7b is.
- the connector angle is 90°.
- angle connection devices with connection angles other than 90°, e.g. B. be provided with a connection angle of 60 °.
- the connecting devices enable flexible and varied assembly and construction of the conductor rods 1 to form the most diverse conductor arrangements.
