As a kind of preferred embodiment of the utility model, the thickness of the laminated polyester film is 0.3-1.8mm.

As a kind of preferred embodiment of the utility model, the housing draws material to be made using aluminium foil wheat.

As a kind of preferred embodiment of the utility model, the core wire includes the signal of interior insulation set and two pair twists Line；The interior insulation set is sheathed on outside two signal wires；The signal wire includes conducting wire and sheath；The sheath is coated on Outside the conducting wire.

As a kind of preferred embodiment of the utility model, the sheath is made of PP materials.

As a kind of preferred embodiment of the utility model, poly- ammonia is filled between the laminated polyester film and the core wire Ester gum.

Through the above technical solutions, the advantageous effect of technical solutions of the utility model is：The utility model is reasonable for structure, system Make at low cost, shielding electric signal effect is good, avoids interfering with each other, and network transfer speeds are fast, while mobile cable will not be because carrying It moves and the signal wire of pair twist is made to become loose, stability is good, and service life is long.
