Abstract
A casing 14 for a junction included in a flat cable 10, e.g. for a trigger stage of a sequential blasting system, consists of two casing portions 12, 13 adapted to be fixed to each other by screwing within the lead-through regions of the cable. The casing portions 12, 13 constitute cramping areas for fixing the cable 10 to the casing 14 in a direct, non-positive way, wherein the screws 23 which interconnect the two casing portions 12, 13 at the same time create the cramping pressure. An additional positive engagement between the cable 10 and the casing 14 is achieved by engagement between a tube 25 which receives the screw 23 and a hole 29 provided in a center web 28 of the cable. Tensile strain occurring within the cable 10 is thus diverted via the casing 14 around the electrical equipment provided in the casing and soldered to the wires 19 of the cable 10. Even under high tensile forces, the soldering points are thus not exposed to any strain.
