Abstract
The utility model discloses a kind of cable with good capability of electromagnetic shielding, including cable core and cable skin, the cable skin being constituted in insulating barrier, the wire netting being wrapped in outside inner insulating layer, the waterproof layer being wrapped in outside wire netting and the external insulation layer that is wrapped in outside waterproof layer outside parcel cable core.The beneficial effects of the utility model are can effectively to lift the capability of electromagnetic shielding of cable, and simple in construction, and cost is relatively low, are adapted to majority of case and are applicable.
Description
Technical field
The utility model is related to field of cables, particularly a kind of cable with good capability of electromagnetic shielding.
Background technology
Cable is the circuit arrangement commonly used in production practices.In order to prevent cable by electromagnetic interference influence service behaviour,
Reply cable, which is made, to be correspondingly improved.
The utility model shielded cable and shielding band of Application No. 201520815418.8 are led with technology of the present utility model
Domain is identical.The utility model of this entitled shielded cable and shielding band possesses signal wire (101), is arranged at signal wire (101) week
The braid shielded thing (102) that encloses, the shielding band (103) being wound in around braid shielded thing (102) and shielding is arranged at (103)
The outer cover (104) of surrounding, shielding band (103) has band base material (201), is arranged at base material (201) outer surface and by containing magnetic
Property body powder and hot-melt type bonding agent magnetic resin composition formation magnetic hot-melt type adhesive linkage (202) and be arranged at
The conductive metal layer (203) formed with base material (201) inner surface and by conductive metal, magnetic hot-melt type adhesive linkage
(202) it is closely sealed with outer cover (104), and conductive metal layer (203) contacts with braid shielded thing (102).
The cable generally used now needs to make its electromagnetism interference performance improvement, although above-mentioned prior art can
Maintain pliability, resistance to bend(ing) and play capability of electromagnetic shielding and magnetic shield performance, but it is complicated, and cost is higher, no
Beneficial to a wide range of popularization.
Utility model content
The purpose of this utility model is to solve the above problems, devise a kind of electricity with good capability of electromagnetic shielding
Cable.
Realize that above-mentioned purpose the technical solution of the utility model is, a kind of cable with good capability of electromagnetic shielding, bag
Include cable core and cable skin, the cable skin outside parcel cable core in insulating barrier, the wire netting being wrapped in outside inner insulating layer, be wrapped in gold
Waterproof layer outside category net is constituted with the external insulation layer for being wrapped in waterproof layer.
The insulating barrier is polyvinyl chloride layer.
It is the wire netting that red copper is made to state wire netting, and the mesh number of the wire netting is 200.
The waterproof layer is polyethylene winding layer.
The external insulation layer is polyvinyl chloride layer.
A kind of cable with good capability of electromagnetic shielding made using the technical solution of the utility model, can be effective
The capability of electromagnetic shielding of cable is lifted, and it is simple in construction, and cost is relatively low, is adapted to majority of case and is applicable.
Brief description of the drawings
Fig. 1 is a kind of structural representation of cable with good capability of electromagnetic shielding described in the utility model；
In figure, 1, cable core；2nd, cable skin；3rd, inner insulating layer；4th, wire netting；5th, waterproof layer；6th, external insulation layer.
Embodiment
The utility model is specifically described below in conjunction with the accompanying drawings, as shown in figure 1, a kind of have good electromagnetic wave shielding
Can cable, including cable core 1 and cable skin 2, the cable skin 2 outside parcel cable core 1 in inner insulating layer 3, be wrapped in inner insulating layer 3
Outer wire netting 4, the waterproof layer 5 being wrapped in outside wire netting 4 and the external insulation layer 6 being wrapped in outside waterproof layer 5 are constituted；The insulation
Layer 3 is polyvinyl chloride layer；The wire netting 4 is the wire netting that red copper is made, and the mesh number of the wire netting 4 is 200；The waterproof
Layer 5 is polyethylene winding layer；The external insulation layer 6 is polyvinyl chloride layer.
The characteristics of the present embodiment is the wire netting being wrapped in outside inner insulating layer, and the material of this wire netting is red copper, mesh
Number is 200, and can effectively reduce the electromagnetic interference that cable is subject to, and be wrapped in the waterproof layer outside wire netting can protect metal
Net is not infiltrated the liquid interference of cable, prevents the accidents such as electric leakage, can effectively lift the capability of electromagnetic shielding of cable, and
And it is simple in construction, cost is relatively low, is adapted to majority of case and is applicable.
In the present embodiment, the wire netting outside inner insulating layer is wrapped in, the material of this wire netting is red copper, and mesh number is
200, can effectively reduce the electromagnetic interference that cable is subject to, and be wrapped in the waterproof layer outside wire netting can protect wire netting not
The liquid interference of cable is infiltrated, prevents the accidents such as electric leakage.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Some variations that personnel may make to some of which part embody principle of the present utility model, belong to the utility model
Protection domain within.
