Description
Technical field
The utility model relates to a kind of cable, is specially the flat shielding cable for digital communication of a kind of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant.
Background technology
Existing flat cable for digital communication, although wiring is installed also more for convenience, but when having the occasion of high-strength magnetic ripple and have the laboratory of precision instrument to use, due to electromagnetic radiation, can produce serious interference to the equipment around cable itself and cable and network, add the conventional PVC sheath material adopted, flameproof effect is undesirable, and a large amount of toxic and harmful and dense smoke can be produced when burning, directly jeopardize the life security of staff.
Utility model content
For above-mentioned technical problem, the utility model discloses the flat shielding cable for digital communication of a kind of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant, comprise cable core, screen, sheath, described cable core comprises four groups of twisted pair wires, often organize twisted pair wire to be mutually entwined by two single lines 1 respectively, the polyethylene layer 12 that described single line 1 comprises copper conductor core 11 and is coated on described copper conductor core 11 outside forms; Described sheath comprises inner sheath 2 and oversheath 3, inner sheath 2 and oversheath 3 are all by the sheath of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant material extrusion forming, the inside of described inner sheath 2 arranges hole, described hole is for holding cable core, described oversheath 3 is wrapped in the outside of described screen 4, and a tinned wird 5 is also set between inner sheath 2 and oversheath 3, it is for conduction current; Described screen 4 is foil shielding layer, is wrapped in the outside of described inner sheath 2 and tinned wird 5.
The beneficial effects of the utility model are: first, by adopting flat Exterior cable shape, can more easily stick on the horizontal or vertical surface of other object, more easily pass through crack between a door and its frame or hide under carpets, building structure or another laid pipes need not be destroyed, wiring is installed and is used more convenient, and installation workload is little; Secondly, by setting up one deck inner sheath and one deck oversheath, and inner sheath and oversheath all adopt Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant material extrusion forming, not only ensure that the convenient of the stable of cable twisted pair wire and following process, and serve good flameproof effect, the toxic and harmful produced when effectively controlling cable fire and the discharge of dense smoke, ensured the life security of personnel, thus the occasion being applicable to more high requirement uses; Finally, by special construction and one deck foil shielding layer of described cable, enhance the ability of cable opposing outside electromagnetic interference, the electromagenetic wave radiation of itself can be controlled again simultaneously, do not disturb the normal work of around other equipment and network, thus be applicable to the occasion of more requirements at the higher level.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the flat shielding cable for digital communication of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1, the utility model discloses the flat shielding cable for digital communication of a kind of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant, comprise cable core, screen, sheath, described cable core comprises four groups of twisted pair wires, often organize twisted pair wire to be mutually entwined by two single lines 1 respectively, the polyethylene layer 12 that described single line 1 comprises copper conductor core 11 and is coated on described copper conductor core 11 outside forms; Described sheath comprises inner sheath 2 and oversheath 3, inner sheath 2 and oversheath 3 are all by the sheath of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant material extrusion forming, the inside of described inner sheath 2 arranges hole, described hole is for holding cable core, described oversheath 3 is wrapped in the outside of described screen 4, and a tinned wird 5 is also set between inner sheath 2 and oversheath 3, it is for conduction current; Described screen 4 is foil shielding layer, is wrapped in the outside of described inner sheath 2 and tinned wird 5.
Specifically tell about the flat shielding cable for digital communication of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant described in the utility model below.
As shown in Figure 1, the global shape of the flat shielding cable for digital communication of described Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant is flat, and centre is four groups of twisted pair wires, often organizes twisted pair wire and can be set to different colors, to distinguish.Twisted pair wire is contained in inner sheath 2 shaping in advance, outside arranged the tinned wird 5 that is played guide functions before this, the diameter of tinned wird 5 is 0.5mm, and then adopt special die and processing technology, coated one deck foil shielding layer 4, finally superscribe one deck oversheath 3 again, inner sheath 2 and oversheath 3 are all by the sheath of Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant material extrusion forming, there is good fire retardation, and owing to having added foil shielding layer, therefore, it is possible to well resist the interference of external electromagnetic, the electromagenetic wave radiation of itself can be controlled again simultaneously, the normal work of around other equipment and network can not be disturbed, be useful in the occasion of high-strength magnetic ripple and the laboratory environment of use precision instrument and use, have highly application value.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
