Connection of a connection fitting for electrical lines with a tension element

The invention relates to a connection fitting for electrical Lines with a tension element, especially for contact lines for electrically powered vehicles

The connection between two elements subject to tensile stress is

achieved by bolts secured against removal · For the I

game is electrically driven Ver j

BcäiüSaxmatur produced in that through the holes at- |

a rivet pin inserted into the parts and secured with a split pin j

TTirdo Such connections have the disadvantage that they only <

are difficult to remove with tools and under certain circumstances «,!

The object of the invention is to provide a connection of an AsschluB-

A cotter pin or equivalent is provided to prevent twisting in the event of sudden strain relief.

Fig. 5 shows a section A ₉ B of the exemplary embodiment shown in FIG. 1. With FIG. 5, the establishment of a connection according to FIG. 1 can easily be explained The end of the Zugeleae & tes 13 is pushed beyond the position shown in Fig. 1, rotated by 90 ° and withdrawn so far that it assumes the position shown in Fig. 1. In order to secure against turning, Z ₀ B. upon sudden relief of the tension element 13, the cotter pin 14 through the corresponding holes of the end parts 11 and of the tension element is inserted, if the end portion 12 of the tension element 13 is not formed bo that it is self-locking. "

With a rectangular cross section of the pull element according to Figure ₉ is 4, the cross-section 19, as well as the cross-section must "be formed according to" 20 of the seat for the end of the tension element · -Figo 6 of the invention "shows a Ausführungebeispiel according to which the end 12 of the tension member is 13 is inserted through a slot 22 in the end part 11 of the connection fitting 10. The end part 11 is suitable in FIG. 6 for receiving an index 12 of the tension element 13 according to FIG. 2. The dashed line 21 indicates that the end 12 can also be conical «,

The shapes of the tension elements shown in the figures may be formed constructively any differently ,, Accordingly have the seats door the ends of the tension members are trained "

The In Flg. 5 shown cross section 19 for introducing the Aides 12 of the tension elements 13 lies in the longitudinal axis

the connection fitting 10 «Ξτ can also be used with a correspondingly changed, constructive formation of the end part 11 lie in a longitudinal axis parallel to the longitudinal axis shown, or in a transverse axis of the end part 11 · In this » fall, the tension element 15 with its end 12 is perpendicular Introduced into this end part on the longitudinal axis of the longitudinal part 11, rotated by 90 ° and pulled into its final position *

The suction elements shown in the figures consist according to of the invention made of glass fiber reinforced plastic, e.g. made of glass fiber reinforced polyester or glass fiber reinforced epoxy Harsfco

The invention means a simple shape for tension isolators as tension elements, the tension isolator does not need to be reinforced in order to * can be connected directly to the connection fitting «, the connection fitting is simpler in its shape and additional fastening parts» a _ο Β _β - bolts and nuts As connection _{fittings z a} B _o wedge end clamps, choke clamps and carrying straps, as they are known from overhead lines of electrically powered vehicles
