Section separator for overhead contact lines in electrical low-level vehicles

The invention relates to section separators for contact lines Gen electrically powered vehicles where the ends of the contact wires are connected by a tension insulator «

The Iaolator * on beateheii in full railways predominantly made of ceramic tiles and in railways with a lower level of supply voltage made of wood or plastics. Insulators made of wood or plastic have poor electrical properties. For example, the arc and creep resistance of these insulators is insufficient compared to insulators made of ceramic materials Section separator is very good! ■ ς u-oil ·

Before «The cross section of the Zugieolators 14 can also be chosen differently _e

Figo 1 and 2 show a section separator where the ends 10, 11 of the contact wires 12, 15 are bent and through a hole in the ends 21 of the tensioner 14 are plugged in. The ends 10, 11 are provided with a thread, and gec; s slipping in Zugrichtuns means of nuts 22 G © - flicherto purpose straight plant of the nuts 22 the ends 21 Cecen dee Zusisolators 14 are the projections 23 for fastening the ends 10, 11 of the contact wires 12 _t 13 is provided. " The contact wire connector clamps usually provided can also be used to fasten the contact wires

The following figures show exemplary embodiments for the type of fastening of the ends of the contact wires in the ends of the train isolator 14c

In FIG. 4, the bent end 10 of the contact wire is pushed through the hole in one end of the pulling rod and by means of press sleeve 25 and disk 26 against pulling out In Babel secured in the direction of pulling is a recess 27 in the find of the pulling device 14 as an abutment for the compression sleeve 25 available·

tfach Fig. 5, the end of the Zugieolators 14 is formed so that the end 10 of the contact wire into the recesses 30 of the two Zugieolatorhälften 29 is inserted old The end 10 of the contact wire is previously by nut or with a Preßhill · «ο» like, secured against pulling out been «. The two same tension isolator halves 29 are by the Kleamhülse 32 or another of the known liittel, e.g. "ferrule, held by the middle Insertion of the ends 10 of the contact wire into the ends 21 of the

Tensile insulator 14, the tensile insulator 14 is free from bending stresses ₀

In Fig ₀ 6 Zugisolator is auegebildet as a loop 3 * and the end 10 so out of the contact wire through the loop that it erfährto no bending stress The filler 31 serves to reduce the mechanical stresses in the end 35 of the loop 34 _O The end 10 of the contact wire is secured against pulling out by nuts »a press sleeve 25 o ^

According to Fi-o 7, the end 10 of the contact wire is only after being inserted through the bore 33 in the end of the pulling wire secured against slipping out by bending, *

In all embodiments, the holes in the Ends of the tension insulator for passing through the ends of the contact wires at right angles or in any other, not shown angle to the lower edge of the insulator are drilled «»

In Fig. 8 in the end 21 of the tension isolator 14 is a screw and a pressure piece 28 for regulating the contact wire position is shown.

In catenaries, which are traversed with Bollen- or grinding shoe pantographs "can also be guided by the insulator, the ends of the contact wires that the insulator can be driven directly _o If the contact line traveled by Bügelstroaabnehmern, so Fig * 1 in accordance to 3, the far usual skids, e.g. ₀ B _P 15, 16 or elastic wires to be arranged, which lift the hoop pantograph slightly from the contact wire «,

By means of the section insulator according to the invention, distinctive advantages achieved in addition to the simplicity in construction and the associated light weight; Montage stands out
