Abstract
The utility model relates to a cable, its insulating layer and parcel insulative sheath outside the insulating layer who includes conductor, parcel conductor, the insulating layer adopts the polytetrafluoroethylene coating film, is favorable to reduce cost.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of cable using teflon insulation.
Background technology
Existing manufacturer is for providing insulating properties and the resistance to elevated temperatures of cable, it is intended to use fluoro-containing plastic to make insulating barrier,
The especially performance of polytetrafluoroethylene (PTFE) (also known as Teflon) is the most prominent.It is real that the prior art relevant to this case is referred to China
Announcing No. 201430207 a kind of coaxial cable disclosed with new patent, it is coaxially disposed inner wire, medium from inside to outside
Layer, outer conductor and coat, dielectric layer uses polytetrafluoroethylene (PTFE), and coat is layer of polyurethane.
Utility model content
The purpose of this utility model there are provided a kind of cable reducing cost.
For realizing object defined above, the utility model adopts the following technical scheme that a kind of cable, and it includes that conductor, parcel are led
The insulating barrier of body and be wrapped in the insulation sheath outside insulating barrier, described insulating barrier uses polytetrafluoroethylene (PTFE) plated film.
As further improvement of the utility model, between described insulating barrier and insulation sheath, it is additionally provided with a screen layer, institute
State screen layer for braiding or metal winding layer.
As further improvement of the utility model, a part of surface of described conductor is coated with insulating barrier, another part table
Face does not covers insulating barrier, and abuts with screen layer, reaches and electrically conducts.
As further improvement of the utility model, described conductor is earth conductor.
As further improvement of the utility model, described conductor is by being positioned at a thick conductor of centre and being arranged in along circle
Some thin conductor outside this thick conductor twists together composition jointly.
As further improvement of the utility model, described conductor includes at least one signal conductor, a power conductor and
Earth conductor, described signal conductor is all coated with insulating barrier with the outer surface of power conductor.
As further improvement of the utility model, described cable does not have Copper Foil and aluminium foil.
The insulating barrier of the utility model cable parcel conductor uses polytetrafluoroethylene (PTFE) plated film, has the advantage that
1. insulating barrier is arranged conveniently, easily, is beneficial to reduce cost.
2. can cancel all Copper Foil/aluminum foil shieldeds.
3. it is easy to arrange conductor.
4. save the station of ground wire of twisting joint.
5. when reducing cable extrusion, the station of strand aluminium foil, reduces production cost.
6. it is advantageously implemented the automatic assembling of cable, saves human cost.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the utility model cable.
Detailed description of the invention
Referring to shown in Fig. 1, the utility model cable 100 is USB 2.0 cable, it include some conductor 11,21,31,
Wrap up the insulating barrier 12 of each conductor 21,21,31,22,32, be wrapped in the screen layer 40 outside all insulating barriers 12,22,32 and
The insulation sheath 50 of parcel screen layer 40.
Conductor 11,21,31 includes two signal conductor 11, power conductor 21 and earth conductors 31, each conductor 21,
21,31 jointly twisted together by the thick conductor and the some thin conductor that is arranged in outside this thick conductor along circle being positioned at centre
Constitute.
Insulating barrier 12,22,32 uses polytetrafluoroethylene (PTFE) plated film, and this plated film is divided into full plated film and Partial coatings two kinds, entirely plates
During film, each conductor 11,21,31 outer surface is all coated with polytetrafluoroethylene (PTFE) plated film；During Partial coatings, it is adaptable to earth conductor
31, a part of outer surface of earth conductor 31 is coated with polytetrafluoroethylene (PTFE) plated film, and another part outer surface does not covers polytetrafluoroethyl-ne
Alkene plated film, be connected to screen layer 40 together with, formed earth-return circuit.In other embodiments, can be a part of insulating barrier
12,22,32 using conventional insulation materials, another part insulating barrier 12,22,32 uses polytetrafluoroethylene (PTFE) plated film, is used in combination, than
As, the insulating barrier 12,22 outside signal conductor 11 and power conductor 21 uses conventional insulation materials, and outside earth conductor 31
Insulating barrier 32 uses polytetrafluoroethylene (PTFE) plated film.
Screen layer 40 is braiding or metal winding layer.
The insulating barrier 12,22,32 of the utility model cable 100 uses polytetrafluoroethylene (PTFE) plated film, has the advantage that
1. insulating barrier 12,22,32 is arranged conveniently, easily, is beneficial to reduce cost.
2. can cancel all Copper Foil/aluminum foil shieldeds.
3. it is easy to arrange conductor 11,21,31.
4. save the station of ground wire of twisting joint.
5. when reducing cable 100 extrusion, the station of strand aluminium foil, reduces production cost.
6. it is advantageously implemented the automatic assembling of cable 100, saves human cost.
