Abstract
The utility model discloses a shielded cable for a computer. The shielded cable comprises a plurality of cores, each core is formed in a manner that conductors coated with insulation layers are twisted in pairs and lapped, a polyvinyl chloride lapping layer is lapped outside each core, a silicon rubber insulation layer is extruded and filled in each lapping layer, a tinned copper wire woven separated shielding layer is coated outside each lapping layer, an inner jacket is coated outside the plurality of cores lapped with the shielding layers, inflaming retarding fillers are filled and extruded in the inner jacket, and a copper strip lapping total shielding layer, a polyester strip, an armor layer and an outer jacket are sequentially coated outside the inner jacket. By adopting a dual-layer shielding design and arranging two layers of inflaming fillers of a glass cord and silicon rubber, the shielded cable has the advantages of effectively improving fire preventing and inflaming retarding properties and anti-interference property of a computer cable, and increasing safety reliability and service life of the cable, and is especially suitable for occasions with dense population and higher requirement of safety reliability to equipment.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of computer and uses shielded type cable.
Background technology
The employed cable of computer is higher than general equipment to the stability requirement of electric current; If electric current is unstable; Computer might produce electricity shortage; Might burn out electric capacity or power supply, also might cause computer to restart automatically, damage the file of computer-internal or the hardware device of computer.The computer cable resistance to elevated temperatures of using at present is not good, interference free performance is not strong, and the security reliability of cable is low under adverse circumstances such as fire, and the proof voltage ability is not good yet, brings certain hidden danger for many work.
The utility model content
The purpose of the utility model provides a kind of computer and uses shielded type cable, to solve the problem that the computer cable resistance to elevated temperatures is not good, interference free performance is not strong in the prior art.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of computer is used shielded type cable; It is characterized in that: include several cores; Every core constitutes by two groups of conductor pair twists that are coated with insulating barrier are wrapped, and every core is surrounded with the polyvinyl chloride lapping layer outward, extrudes in the said lapping layer and is filled with silicon rubber; Said lapping layer is coated with tinned copper wire braiding sub-shield; Several cores that are surrounded with sub-shield are coated with inner sheath, extrude in the said inner sheath to be filled with fire-retardant filler, and said inner sheath is coated with the wrapped total screen of copper strips, polyester belt, armour and oversheath outward successively.
Described a kind of computer is used shielded type cable, it is characterized in that: said fire-retardant filler is a glass cord.
Described a kind of computer is used shielded type cable, it is characterized in that: said armour is double-deck steel-tape armouring.
The beneficial effect of the utility model is:
The utility model adopts the design of double layer screen; And be provided with the two-layer fire-retardant filler of glass cord and silicon rubber; The fire retardant performance and the interference free performance of computer cable have been promoted effectively; The security reliability and the useful life of also having improved cable simultaneously, be particularly suitable for densely populated and higher place to the device security reliability requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes several cores 1; Every core 1 constitutes by two groups of conductor pair twists that are coated with insulating barrier are wrapped, and every core 1 is outer to be surrounded with polyvinyl chloride lapping layer 2, extrudes in the lapping layer 2 and is filled with silicon rubber 4; Lapping layer 2 is coated with tinned copper wire braiding sub-shield 3; Several cores 1 that are surrounded with sub-shield 3 are coated with inner sheath 6, extrude in the inner sheath 6 to be filled with fire-retardant filler 5, and inner sheath 6 is outer to be coated with the wrapped total screen of copper strips 7, polyester belt 8, armour 9 and oversheath 10 successively.
Fire-retardantly fill out 5 to fill thing be glass cord.Armour 9 is double-deck steel-tape armouring.
