Abstract
The utility model relates to a polyvinyl chloride insulation sleeve shielding flexible wire (RVVP) shielding power supply control line which comprises a twisted pair formed by two leads, an aluminium foil layer, a copper woven mesh and a polyvinyl chloride (PVC) jacket, wherein each lead comprises a core wire and a poly ethylene (PE) insulating layer covered on the core wire; the twisted pair is covered by the aluminium foil layer; and the outer surface of the aluminium foil layer is sequentially provided with the copper woven mesh and the PVC jacket. According to the RVVP shielding power supply control line, the twisted pair is covered by the aluminium foil layer and the copper woven mesh, so that the shielding performance of the control line is greatly improved.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of RVVP shielded power supply control line, belongs to technical field of electric wires and cables.
Background technology
The power control line of prior art is made up of lead and insulating barrier two parts usually, and its shielding properties is relatively poor, and outer signals is disturbed control signal easily, and therefore, its result of use is relatively poor.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved RVVP shielded power supply control line that has is provided, to overcome said defective of the prior art.
The utility model content
For addressing the above problem, the purpose of the utility model is to provide a kind of RVVP shielded power supply control line of advantages of good shielding performance.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of RVVP shielded power supply control line, and it comprises twisted-pair feeder, aluminium foil layer, copper mesh grid and the PVC sheath of being made up of two leads; Wherein, each lead comprises a heart yearn and is coated on the PE insulating barrier on the heart yearn; Said aluminium foil layer is coated on the twisted-pair feeder, is provided with said copper mesh grid and PVC sheath successively in the outer surface of aluminium foil layer.
The RVVP shielded power supply control line of the utility model further is set to: said heart yearn is a copper free wire.
Compared with prior art, the utlity model has following beneficial effect: the RVVP shielded power supply control line of the utility model passes through on twisted-pair feeder, to coat aluminium foil layer and copper mesh grid, thereby the shielding properties of this control line is improved greatly.
Description of drawings
Fig. 1 is the profile of the RVVP shielded power supply control line of the utility model.
Embodiment
See also shown in the Figure of description 1, the utility model is a kind of RVVP shielded power supply control line, and it is made up of several parts such as twisted-pair feeder 1, aluminium foil layer 2, copper mesh grid 3 and PVC sheaths 4.
Wherein, said twisted-pair feeder 1 is made up of two leads, and each lead comprises a heart yearn 11 and is coated on the PE insulating barrier 12 on the heart yearn 11, thereby two leads are not disturbed mutually.Said heart yearn 11 is specially copper free wire, thereby makes the transmission speed of this control line fast, good stability, and the error rate is low.
Said aluminium foil layer 2 is coated on the twisted-pair feeder 1, is provided with said copper mesh grid 3 and PVC sheath 4 successively in the outer surface of aluminium foil layer 2.Through coating aluminium foil layer 2 and copper mesh grid 3 on twisted-pair feeder 1, thereby the shielding properties of this control line is improved greatly.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
