Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, a micro sensor cable includes the cable core that is formed by the 1 transposition of conductor that six bundles of parcels have insulating layer 2, the cable core sets gradually shielding layer 4, interior sheath 5 and the outer jacket 6 of winding type structure outward, the thickness of outer jacket 6 is 0.2mm, and the material is resistant polyether polyurethane of waiting, six bundles of parcels have insulating layer 2's conductor 1 around the periphery of aramid fiber filler 3.

The sensor cable is designed into a cable core formed by twisting six strands of peripheral conductors 1 surrounding aramid fiber fillers 3, a shielding layer, a thin-wall inner protection layer, a thin-wall outer protection layer and other structures of a winding structure are arranged outside the cable core, and the aramid fiber fillers 3 are arranged at the gaps of the conductors, so that the outer diameter of the cable is greatly reduced under the condition that the stability of the whole cable is ensured, and the sensor cable can meet the application requirement of a micro sensor.

Through selecting for use the outer jacket 6 of the resistant polyether type polyurethane material of waiting that thickness is 0.2mm, to the existing certain guard action of cable, remain suitable mechanical strength again to do the end seal in the later stage does benefit to, because fluoroplastics are difficult to do the connector. Meanwhile, the six stranded conductors are adopted to ensure the flexibility and the bending performance of the cable.

The color of six strands of conductors 1 is red, yellow, blue, green, white, black respectively, and the material is FEP material, and the color separation is carried out to conductor 1 in order to distinguish the sinle silk when using, conveniently connects and distinguishes different return circuits. By adopting FEP, the cable has excellent electrical and mechanical properties and is convenient to process ultrathin insulation.

The thickness of insulating layer 2 is 0.06mm, the material of insulating layer is FEP, under the condition of reducing the cable external diameter by a wide margin, has kept the excellent electrical properties of cable. In order to ensure the size of the cable, the insulation layer 2 needs to be ultra-thin insulation, which is difficult to realize by PVC and PE, and can be realized by FEP.

The shielding layer 4 of the winding type structure is formed by winding 48-50 tinned copper wires with the diameter of 0.06mm in the left direction, and according to the diameter of the cable core and the diameter of the wound monofilaments, the shielding density can be effectively guaranteed by winding 48-50 tinned copper wires with the diameter of 0.06 mm.
