The invention relates to a cable connection sleeve that ■ consists essentially of cast resin and with a conductive connection of the reinforcement or the concentric screen of the connected cables or lines within the hoof body is provided.

The production of a connection on a cast resin basis Cables with metallic armouring or concentric conductors mean an interruption of the armouring or dee conxeal smell Head and the job function "£ & die." Protective function of the reinforcement or the electrical! »Chimes is severely devalued by an interruption at the connection point, a conductive protective arrangement is also required in the area of the connecting sleeve

The formation of this conductive protective arrangement is at dtr Invention essential. So far, for example, a basket-like " Formation of individual, roughly parallel flat or round wires used on the ends of the reinforcement both cables are applied. The basket could be in the middle

Area widened or cylindrical * Ea is also a trap-like protective or neutral conductor section made of metal wires that surrounds the entire connection point, for this purpose it became known »After all, they are used to pull in cables and as expansion protection for line connection points Wire mesh drawstring socks known.

The invention relates to a cast resin-based cable connection sleeve with a conductive connection of the reinforcements or the concentric conductors of the cables or lines within the sleeve body with the characteristic that a flat or round wire braided metal hose in the manner of a cable pulls it, which at the ends of the reinforcement or of the concentric conductor mechanically feet _v and good electrically-conductively attached and 1st then firmly embedded by means of insert molding and curing of the casting resin, is used as conductive connection "Since the request is addressed to the cable manufacturer, in the shield no gaps over a determined en maximum value, In Germany, for example, 4 mm, a correspondingly tightly braided metal hose IU must be used.It can be made of copper or aluminum wires, for example, if the requirement for a specific electrical conductor cross-section is in the foreground - or, for example, from. surface hen-treated steel wires, if special mechanical requirements have to be taken into account

The braided hose used according to the invention has opposite other protective structures have the advantage of greater flexibility

with sufficient rigidity after completion of assembly. He is suitable Sun building a protection system when connecting single-core as well as when connecting multi-core or multi-core Cables and lines using cast resin sleeves «Through the The internal stiffness of the braided hose can be adjusted to the stresses during assembly Safety distances between the ladders, bsw. reach and adhere to their solder sleeves and the Sohutzgefleoht.

Structure and type of production of a casting resin connection sleeve with such a braid will be explained in more detail below explained.

When establishing a cable connection between two single or multi-core cables, the braided hose is first opened one end of the cable pushed on, then the two cables in the conventional manner after stripping the conductor and Deposition of the common covering, reinforcement and the jacket in the distances corresponding to the Oießharzverbindungsmuffe tied together.

After the cable connection is established, the fleece hose so pushed over the junction of the cable that its one end of the in a corresponding manner exposed reinforcement or the concentric conductor. By wrapping it with a wire bundle and then soldering it mechanical strength and a good conductive connection
