Abstract
The utility model discloses a computer cable comprising a cable core, a polyester belt, a copper belt shielding layer, a wrapping belt and an outer sheath, which are arranged in sequence from inside to outside, wherein the cable core comprises a conductor and a polyethylene insulating layer, a first polyester belt, a copper belt shielding layer and a second polyester belt, which are wrapped in sequence outside the conductor; fillers are arranged between the polyethylene insulating layer and the polyester belts of the cable core; a filler is arranged between the cable core and the polyester belt positioned outside the cable core; and the fillers are made of non-hygroscopic non-conducting materials. The computer cable comprises the two shielding layers which have a good shielding effect and can effectively reduce the external interference to the cable and reduce the interference of the cable to the external environment, adopts the polyester belts to greatly improve the tensile strength, reduces the production costs, and is more safe and convenient to use. Besides, the fillers are non-hygroscopic and non-conductive and can serve the water-blocking and the fire-proofing functions, so that the application range of the cable is expanded and the service life of the cable is prolonged.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of electrical cable.
Background technology
Electric wire is meant the material that is used for electric power, communication and associated transport purposes.Along with the continuous expansion of industry sizes such as power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.Computer cable is mainly used in rated voltage 500V and followingly is connected with automation for the higher electronic computer of anti-tampering performance requirement.The deriving of electric wire/new product mainly be in response to occasion, application requirements is different and the convenience of equipment and reduce the requirement of equipment cost etc., and adopt new material, special material or change product structure or improve technological requirement and produce.
The utility model content
The purpose of this utility model provides a kind of computer cable of architecture advances, has the characteristics of good, the applied widely and long service life of shield effectiveness.
For achieving the above object, by the following technical solutions:
A kind of computer cable comprises core, polyester belt, copper strips screen, twining package tape and oversheath from inside to outside successively, and wherein, described core comprises conductor and wraps up its outer polyethylene layer, polyester belt, copper strips screen and polyester belt successively; Contain filler between the polyethylene layer of described core and polyester belt; Contain filler between described core and its outer polyester belt.
Optionally, described filler is other non-moisture absorptions and fire-retardant non-conducting materials such as polypropylene rope, glass cord, asbestos cord, rubber or nonwoven fabrics.
The utility model comprises two-layer copper strips screen, thereby has good shield effectiveness, can effectively reduce outer bound pair cable and cable interference to external world, makes computer and other automation equipment work more stable; Polyester belt has good tensile property, and good springiness, corrosion-resistant, cost is low, has strengthened combination property of the present utility model greatly, and has reduced production cost, uses also safer, convenient; Contained filler is non-hygroscopic non-conductive, and block water, fire-resistant effect is good, thereby widened the scope of application of the present utility model and prolonged its useful life.
