Abstract
The utility model discloses a two-core twisted pair computer cable. The two-core twisted pair computer cable comprises a cable core; a second filling layer is arranged at the gap of the cable core; the cable core is wrapped by a second wrapping band; a shielding layer is wrapped by the high-strength aramid fiber yarn wrapping band in an extruding manner; the outer most layer of the cable core is wrapped by an oversheath in an extruding manner; the cable core is formed by twisting two insulating wire cores; each insulating wire core is composed of a pair of twisting leads at the center and a first wrapping band wrapped outside the leads in an extruding manner; each lead is composed of a conductor and an insulating layer wrapped outside the conductor in an extruding manner; and the gap of the insulating wire cores is provided with a first filling layer. The two-core twisted pair computer cable has the advantages of high flame resistance property; no harmful gas is generated when the cable is combusted so that secondary damage is avoided and damage to people is reduced; the service life of the cable is prolonged, and the two-core twisted pair computer cable can be applied to a computer, a detection instrument and other instruments.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of two core pair twist computer cables.
Background technology
The signal transmission of the current distributing system in industrial and mining enterprises such as electric power, metallurgy, chemical industry, electronic computer system, automated system and detecting instrument, instrument etc. connect with multipair SHIELDING CALCULATION electric cable, basically adopt traditional polythene insulation PVC sheath shield type computer cable.This cable has the polyethylene of the superior electrical performances such as dielectric constant is little, dielectric loss is little, insulation resistance is large as insulating material, so cable has low electric capacity, inductance and stablizes good transmission performance because of employing.But along with some problems that are widely used of this cable occur thereupon, mainly to there is the occasion of anti-flammability performance at the ask for something cable, because this cable insulation adopts polythene material but polyethylene is combustible material, contain halogen, once breaking out of fire, will discharge toxic gas, to people, bring harm; Computer cable generally is applied in precision instrument and equipment in addition, and these corrosive gass that contain halogen can cause serious sour corrosion to equipment.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of anti-flammability is high, burning the time does not produce pernicious gas, has avoided secondary injury, has reduced the injury to people, two core pair twist computer cables of long service life.
A kind of two core pair twist computer cables described in the utility model, comprise cable core, in the gap of cable core, is provided with the second packed layer, outer wrapped the second twining package tape of cable core, and high strength aramid yarn twining package tape extrudes screen outward, and the cable core outermost layer extrudes oversheath; Described cable core is to be formed by two eradication edge core pair twists, and one group, its insulated wire cores Shi You center pair twist wire and the first twining package tape be extruded in outside wire form.
Further improve, described wire is by conductor and be extruded in the outer insulating barrier of conductor and form.
Further improve, described insulated wire cores gap also is provided with the first packed layer.
Further improve, described the first twining package tape, the second twining package tape consist of the braiding aramid yarn.
Further improve, described screen consists of the metal armouring structure again.
The beneficial effects of the utility model are:
Compared with prior art, the utility model adopts double-deck aramid yarn twining package tape, and the metal armouring screen has increased the anti-flammability of cable, insulated wire cores adopts wire pair twist structure, strengthened self anti-flammability, insulating properties, when breaking out of fire, cable is not easy damaged, do not adopt polythene material, can the poisonous corrosive gas of output, alleviated the injury to people, also increased the useful life of cable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of two core pair twist computer cables described in the utility model, comprise cable core, be provided with the second packed layer 5 in the gap of cable core, outer wrapped the second twining package tape 6 of cable core, high strength aramid yarn twining package tape 6 is outer extrudes screen 7, and the cable core outermost layer extrudes oversheath 8; Described cable core is to be formed by two eradication edge core pair twists, and one group, its insulated wire cores Shi You center pair twist wire and the first twining package tape 4 be extruded in outside wire form.Described wire is by conductor 1 and be extruded in the outer insulating barrier 2 of conductor 1 and form; The insulated wire cores gap is provided with the first packed layer 3.
The first twining package tape 4 described above, the second twining package tape 6 consist of the braiding aramid yarn; Described screen 7 consists of the metal armouring structure.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
