Elastic kink protection for electrical cables »

For electrical cables, means are used at similar cable entries in devices, connecting elements, which prevent the cable from kinking sharply. Metallic spiral springs are known for such purposes, which are reinforced at the attached end by winding several turns over one another * while the other end is intended to prevent the cord from chafing with a smooth eyelet. Sine Another embodiment consists of a cylindrical (rummiföriastücki wherein the fixed sin an end amplification is provided for fastening · Tielfach be slid over the line also (xuauaischläuehe, which are widened with three-pronged Speaialzangen _r is in these so-called coamings at umklöppelten lines the ümklöppelung at the same time held »

The above-described arrangements adhere to considerable deficiencies, in such a way that the metal spiral springs are subject to considerable abrasion of the cable at the outlet end * even if smooth metal parts are provided, in addition, the metallic springs are overstressed by the stress: in practice, so that they are relatively short use out of shape and finally their Zweek miss · Deferred <xummitüülext indeed reinforce the cord, but do not make the required bend protection * Slide-out Summifonastücke cylindrical section and uniform wall thickness not prevent _r because the cord £ but bends at the fastening end, whereby the desired is protection is not attained * is essential is that in all known assemblies no fluid sealing _r run on the line along the given "in this way, a short circuit and shock hazard to the operator" -

Re. ÜSUrauUliöUlUa ti «ArSMXineXUbUig Page:

Compared to the known versions, a new one is more elastic Kink protection for electrical cables described, which the aforementioned Disadvantages do not stick. This kink protection is characterized in that one adapted to the line cross-section Cover made of elastic, electrical insulating material with a *, tapered wall thickness towards the cable entry where, the cable entry is marked by a cone or and labeled paragraphs an adaptation to the cable diameter used by cutting off the cable entry allowed and that a collar or bead is provided at the fastening end is, with which the kink protection is held in the connection element, the sheath is inserted into the connection element with a shoulder be increased, that ela-3tische of different hardnesses, electrical insulating materials are brought together in such a way that that the rope is harder at the attachment end, for example Made of soft rubber with different Shore hardnesses.

Such an anti-kink protection has considerable advantages over the known designs, dean, once an effective anti-kink protection is achieved, furthermore a seal between the line and anti-kink protection, so that liquids cannot flow along the cord into the electrical device * If this is not prevented, there is a danger _y that the operator is in a galvanic connection with the power network via the liquid path that is in galvanic connection with the connection contacts. Another advantage can be seen in the approach carried out in the connection element, dema. Through this, the collar or the lulst, which are used for anchoring in the connecting element, receives the necessary support, because otherwise the elastic material

JO to give slightly _r and could from the opposite groove or courage herausspringett. The kink protection is achieved by the wall thickness of the sleeve, which tapers towards the cable entry, or this effect can be supported or achieved by materials of different hardness ». Ber _r resilient electrical insulating material is soft and easy on the line because the sheath iat flexible along its entire length. The arrangement described works for all common line cross-sections, including flat cables
