The invention relates to the technical field of computer cables. The invention further discloses an intrinsic safety halogen-free flame-retardant computer cable. The cable comprises an outer sheath, the inner side of the outer sheath is fixedly connected with a steel tape armoring layer, the inner side of the steel tape armoring layer is fixedly connected with an inner sheath, a rotating shaft isfixedly installed in the inner sheath, the upper side of the rotating shaft is rotatably connected with a first fire retardant layer, and the lower side of the rotating shaft is rotatably connected with a second fire retardant layer. A support plate drives a support column to extrude an arc-shaped pressing plate to slide towards one end of the outer side; further, the arc-shaped pressing plate extrudes the first fire-retardant layer and the second fire-retardant layer towards the outer side; the first fire-retardant layer and the second fire-retardant layer are combined together through connecting grooves and connecting protruding blocks under extrusion of the arc-shaped pressing plate. Furthermore, the first flame retardant layer and the second flame retardant layer form a protective ringlayer on the inner side wall of the inner sheath, the inner side of the first flame retardant layer is isolated from the outer side of the first flame retardant layer, fire is prevented from spreading to the outer side of a cable core, and therefore, the high-safety physical flame-retardant effect is achieved.
Description
technical field [0001] The invention relates to the technical field of computer cables, in particular to an intrinsically safe halogen-free flame-retardant computer cable. Background technique [0002] With the continuous advancement of science and technology, computers are widely used in various production and service fields such as communications, electronics, petroleum, chemical industry, textiles, and coal mines. During the operation of computers, cables need to provide them with stable current and voltage. It is required that its cables must have excellent anti-electromagnetic interference performance. In addition, in order to ensure that the computer can still operate safely and stably in harsh environments, the cables have low capacitance, low inductance, flame retardancy, toughness, tensile strength, Impact strength is also an essential excellent performance. As an excellent cable for computers, how to achieve both anti-electromagnetic interference performance, low c...
