Furthermore, the intermediate level material is any one of PET, PP, PI, first glue film with the second glue film is the hot melt adhesive.

Further, the outer tegument layer is transversely wrapped outside the shielding layer.

Further, the coating layer comprises an inner adhesive layer connected with the second adhesive layer and an outer film layer connected with the inner adhesive layer.

Further, the outer film layer is made of any one of PET, PP and PI, and the inner adhesive layer is hot melt adhesive.

Further, the cladding layers are longitudinally attached to the upper side and the lower side of the core wire group.

Further, the core wire set further includes at least one ground wire disposed between the shield layer and the outer layer.

Furthermore, two ground wires are arranged, and the two ground wires are respectively positioned on two sides of the core wires and positioned on an extension line of the central line of the inner conductor.

Further, the shielding layer comprises an insulating layer and a metal layer.

Furthermore, the insulating layer of the shielding layer is made of PET, and the metal layer is made of Al.

Compared with the prior art, the utility model has the advantages of: the utility model provides a cable tegument adopts the structure of double-sided tape glue for the structure is more stable after core line group and coating laminating, is difficult to loose the droing.

[ detailed description ] A

Referring to fig. 1 to 2, a cable 100 according to the present invention is shown. The cable 100 comprises a plurality of core wire groups 101 arranged side by side and a plurality of coating layers 102 arranged outside the core wire groups 101, wherein each core wire group 101 comprises a pair of core wires 10, a shielding layer 20 coated outside the core wires 10 and a coating layer 30 coated outside the shielding layer 20, each core wire 10 comprises an inner conductor 11 and an insulating layer 12 coated outside the inner conductor, and the coating layer 30 comprises a first adhesive layer 31 adhered to the shielding layer 20, a second adhesive layer 32 adhered to the coating layers 102 and a middle layer 33 connected with the first adhesive layer and the second adhesive layer.

In this embodiment, two ground wires 50 are disposed between the shielding layer 20 and the outer layer 30, and the ground wires 50 are located on the left and right sides of the pair of core wires 10 and on the extension of the center line of the inner conductor of the pair of core wires 10. In other embodiments, only one ground line may be disposed between the shielding layer and the outer layer, and the disposed position is not limited in this application. The shielding layer 20 includes an insulating layer and a metal layer facing the ground line 50, the insulating layer is made of PET (polyethylene terephthalate, chinese full name), and the metal layer is made of aluminum. Two corresponding air gaps 60 are formed between the shielding layer 20 and the pair of core wires 10 at upper and lower sides thereof.

The middle layer 33 is made of any one of PET, PP (polypropylene, chinese full name) and PI (polyimide), and the first adhesive layer 31 and the second adhesive layer 32 are both hot melt adhesives. The outer layer 30 is wrapped transversely outside the shielding layer 20. The cover layer 102 includes an inner adhesive layer connected to the second adhesive layer 32 and an outer film layer connected to the inner adhesive layer.
