Description
Technical field
The utility model belongs to cable manufacturing field, and in particular to a kind of copper core polyvinyl chloride insulation sheath flexible cord.
Background technology
Copper core polyvinyl chloride insulation sheath flexible cord is generally used for often moving and curved occasion, and existing copper core polychlorostyrene
Ethene insulating sheath flexible cord is generally wrapped in copper core periphery using polyvinyl chloride insulation sheath, because of unshielded layer, is using process
In, easily occur damaged, with insulating tape repair customary, so there are security risk, or even safe thing can be triggered
Therefore and poor flame retardant properties, because cable trigger fire can be found everywhere, therefore existing copper core polyvinyl chloride insulation sheath flexible cord need
Improved, to ensure the security used.
Utility model content
The purpose of this utility model provides a kind of copper core polyvinyl chloride insulation sheath flexible cord, has good mechanical strength,
To ensure the security used.
The utility model provides following technical solution：
A kind of copper core polyvinyl chloride insulation sheath flexible cord, including copper core, copper core periphery are equipped with TPE glue-lines, the TPE glue-lines
Periphery is equipped with and is equipped with polytetrafluoroethylene ethylene layer, glass layer and pvc sheath successively.
Preferably, the pvc sheath uses PVC fire proofings；PVC fire proofings can improve the polyvinyl chloride
The fire resistance of sheath.
Preferably, the copper core and the TPE glue-lines combination are encapsulated using TPE.
Preferably, the polytetrafluoroethylene (PTFE) layer thickness is 1.0 to 1.5 millimeters.
Preferably, the wall thickness of the pvc sheath is 2.0 to 2.35 millimeters.
The beneficial effects of the utility model：
(1) the use of the new type is wrapped in copper core periphery by TPE glue-lines and plays contining function, can improve the mechanicalness of cable
Energy.
(2) glass layer of the utility model has good heat resistance, insulating properties and mechanical strength, can both improve resistance to
Fire can improve mechanical strength, the insulating properties of cable again.
(3) the utility model carries out isolated insulation using polytetrafluoroethylene (PTFE) and polyvinyl chloride, improves the utility model
Insulating properties.
Brief description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form the limitation to the utility model.In the accompanying drawings：
Fig. 1 is the utility model structure diagram；
In figure mark for：1st, copper core；2nd, TPE glue-lines；3rd, polytetrafluoroethylene ethylene layer；4th, glass layer；5th, polyvinyl chloride protects
Set.
Embodiment
As shown in Figure 1, a kind of copper core polyvinyl chloride insulation sheath flexible cord, including copper core 1, the periphery of copper core 1 are equipped with TPE glue-lines

The periphery of copper core 1 is wrapped in by TPE glue-lines 2 and plays contining function, the mechanical performance of cable can be improved；Glass fibre
Layer 4 has good heat resistance, insulating properties and mechanical strength, can not only improve fire resistance but also can improve the mechanical strength, exhausted of cable
Edge, and TPE glue-lines 2 and glass layer 4 have the suppleness that pliability can ensure that cable；Tetrafluoroethene layer 3 and polychlorostyrene second
Alkene sheath 5 has good insulating properties and pliability, not only can ensure that the insulating properties of the utility model, but also and can ensure that cable in itself
Pliability；Wherein, glass layer 4 is arranged between polytetrafluoroethylene ethylene layer 3 and pvc sheath 5, can be by tetrafluoroethene layer 3
Separated with pvc sheath 5, play good flame retardant effect.
Wherein, pvc sheath 5 uses PVC fire proofings；PVC fire proofings can improve the resistance to of pvc sheath 5
Fire
Wherein, 3 thickness of polytetrafluoroethylene ethylene layer is 1.0 to 1.5 millimeters, this 3 pliability of thickness polytetrafluoroethylene ethylene layer and insulation
Property is good；The wall thickness of pvc sheath 5 is 2.0 to 2.35 millimeters, the pvc sheath 5 of this thickness has concurrently good flexible
Property and insulating properties
The advantages of the utility model：
As shown in Figure 1, being wrapped in the periphery of copper core 1 by TPE glue-lines 2 plays contining function, the mechanicalness of cable can be improved
Energy；Glass layer 4 has good heat resistance, insulating properties and mechanical strength, can not only improve fire resistance but also can improve cable
Mechanical strength, insulating properties, and TPE glue-lines 2 and glass layer 4 have the suppleness that pliability can ensure that cable；Tetrafluoroethene
Layer 3 and pvc sheath 5 have good insulating properties and pliability, not only can ensure that the insulating properties of the utility model, but also and can
Ensure the pliability of cable in itself.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, although ginseng
The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with
Modify to the technical solution described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should be included in this practicality
Within new protection domain.
