A tap insert, which includes a coupler assembly, is mounted to the housing, and the coupler assembly is inserted through the entry of the recess and through the opening into the cavity formed in the cable. In specific embodiments, the recess and opening are elongated.

Abstract: An electric noise suppressor is provided for suppressing high-frequency electric noise which comprises a thermoplastic housing and two ferrite members disposed therein. The thermoplastic housing is formed from two hingedly connected case halves, which are substantially identical. A ferrite member is secured to each case half by a laminated compressible adhesive-foam element, which is comprised of a resilient foam core layer and opposing adhesive layers disposed thereabout.

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.
