Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of skeleton answering machine data transmission cable described in the utility model comprises four copper conductors 2, tape wrap layer 4 and two earial drainage copper conductors 11, the outer insulating barrier 1 that is all wrapped in of copper conductor 2, the insulating barrier 1 that insulated single wire by copper conductor 2 and copper conductor outer wrapping forms, it also comprises the skeleton 3 at the center of being arranged on, and the cross section of skeleton 3 is " ten " word shape, and four angle lines of skeleton 3 are positive tetragonal structure, can strengthen the balance of skeleton 3 like this, make cable core structure stable.
Four insulated single wires that copper conductor 2 and insulating barrier 3 form surround positive square shape, and four insulated single wires that copper conductor 2 and insulating barrier 3 form are separately positioned on the frame-saw of skeleton 3; Tape wrap layer 4 is wrapped in four insulating barriers 1, and tape wrap layer 4 is wrapped with one side plastic-aluminum belt 5; Two earial drainage copper conductors 11 are arranged between tape wrap layer 4 and one side plastic-aluminum belt 5.When cable produces eddy current static under strong-electromagnetic field environment, the aluminium material surface of one side plastic-aluminum belt 5 inwardly arranges, and can allow like this aluminium material surface be connected with earial drainage copper conductor 11, thereby play earial drainage effect.
One side plastic-aluminum belt 5 is wrapped with inner covering 1, and inner covering 1 is wrapped with aluminium sheath 7, and aluminium sheath 7 is wrapped with inner covering 28, and inner covering 28 is wrapped with armour 9, and armour 9 is wrapped with oversheath 10.Skeleton 3 adopts PE material to make, and dielectric constant is relatively low.
As a kind of optimal way of the utility model, four outer surface 3-2 of described skeleton 3 are arc shape, and the arc diameter of this outer surface 3-2 and the length of side L of skeleton 3 should equate with the external diameter of insulating barrier 1, are 3.75mm; The arc degree of outer surface 3-2 is 90 degree.The outer surface 3-2 of this arc shape can allow four insulating barriers 1 more can be adjacent to the outer surface 3-2 of skeleton 3, makes cable core structure more stable.
Do not increasing on the basis of the outside diameter of cable, the centre of described skeleton 3 is provided with through hole 3-1, and the diameter of this through hole 3-1 is 0.8mm, by increasing air sectional area, reduces the relative dielectric constant of cable, thereby effectively reduces the impact of skeleton 3 on electric property.
