Summary of the invention
Goal of the invention of the present utility model is: in order to solve the problem above existed in prior art, the utility model proposes that a kind of impedance is low, toughness strong, the multicore holding wire of simple in construction.
The technical solution of the utility model is: a kind of multicore holding wire, it is characterised in that include many roots holding wire and be wrapped in the insulating barrier, screen layer, flame retardant coating and the sheath that set gradually from inside to outside outside many roots holding wire；Described subsignal line includes the core, conductive layer, sub-screen layer, insulating sublayer layer and the sub-sheath that set gradually from inside to outside；Described core includes pliability fibre bundle and is helically wound around the metallic foil on described pliability fibre bundle surface；Described conductive layer includes many to be had the parallel of same circular cross-section and connects metal wire；Described metal wire is helically wound around described core surface, and being can continuous conduction structure；Being provided with radiation dividing plate in described insulating barrier, the holding wire of root more than many is isolated by described dividing plate one by one.
Further, gasket for packing and cooling conduit it are provided with between described insulating barrier and subsignal line.
Further, reinforcement body it is provided with between described screen layer and flame retardant coating.
Further, abrasion resistant particles packed layer it is provided with between described flame retardant coating and sheath.
The beneficial effects of the utility model are: this utility model adopts pliability fibre bundle as core, and uses conductive layer to be wound in core surface, substantially increases the pliability of holding wire, and makes holding wire have relatively low impedance；Meanwhile, being utilized respectively insulating barrier, screen layer, flame retardant coating and sheath and holding wire is carried out multiple-protection, improve the stability in use of holding wire, simple in construction, the suitability is good；Dividing plate is additionally utilized to be isolated one by one by subsignal line, thus preventing subsignal line from interfering, it is to avoid holding wire causes the phenomenon of flattening when complications so that holding wire not easily breaks.
