Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1, the robot towline cable of the present invention includes an outer sheath 1 and a conductor 2, and a teflon tape 3 and an aluminum foil 4 are sequentially disposed between the conductor 2 and the outer sheath 1. Teflon tape 3 has replaced the non-woven fabrics band in the prior art cable, and aluminium foil 4 has replaced the inner sheath in the prior art cable, makes the diameter of cable reduce to 8.1mm by prior art 9.2mm through such structure. Because the bending radius is determined by the outer diameter of the cable, the bending radius is reduced due to the reduction of the outer diameter of the cable, so that the cable can be used in a narrower space, and the application range of the cable is expanded.

In one embodiment, the conductor 2 is formed by twisting a plurality of copper wires, and the plurality of copper wires can improve the conductive capability of the cable.

In one embodiment, the conductor 2 is provided with insulating layers 5 on the outside, and the adjacent insulating layers 5 are tangent to each other. The insulating layers 5 are made of modified polyvinyl chloride mixture and have good insulating performance, and the adjacent insulating layers 5 are tangent to prevent the conductor 2 from loosening in the Teflon wrapping belt 3 and prevent the cable from becoming non-circular.

In one embodiment, all the insulating layers 5 are externally wrapped with teflon tape 3, and the teflon tape 3 is tangent to the insulating layers 5. The Teflon wrapping belt 3 wraps the inner body with the insulating layer 5, so that the conductor 2 is not easy to scatter, and the Teflon wrapping belt has high insulating property, is flame-retardant, high-temperature resistant, low-temperature resistant, ageing resistant and chemical corrosion resistant. The Teflon wrapping tape can be used for a long time at the temperature of 200 ℃ and can bear the high temperature of 260 ℃ in a short time; the material has good mechanical toughness, can maintain 5 percent of elongation even if the temperature is reduced to-196 ℃, and can still maintain the soft characteristic at-100 ℃; the aging is not easy, and the service life is long; the high-voltage insulation material has excellent electrical performance, is an ideal C-level insulation material, can block 1500V high voltage by a thick layer of Teflon, and has no temperature influence on electrical insulation; the dielectric constant and dielectric loss are low in a wide frequency range, and the breakdown voltage, volume resistivity and arc resistance are high. Therefore, the Teflon tape 3 not only improves the comprehensive performance of the cable, but also can reduce the diameter of the cable, thereby reducing the bending radius. The Teflon tape 3 is tangent to the insulating layer 5, so that the Teflon tape 3 can tightly wrap the insulating layer 5 inside the Teflon tape.

In one embodiment, a filler 6 is disposed in the gap between the teflon tape 3 and the insulating layer 5, and both the insulating layer 5 and the teflon tape 3 are tangent to the filler 6. The filler 6 can increase the strength of the cable, and the insulating layer 5 and the teflon belting 3 are tangent to the filler 6 to prevent the conductor 2 in the teflon belting 3 from loosening.

In one embodiment, the aluminum foil 4 is a thermally bonded aluminum foil. The aluminum foil 4 can be more tightly attached to the Teflon tape 3 at a lower preheating temperature.

In one embodiment, the thermal bonding aluminum foil is bonded to the outer wall of the teflon tape 3. The hot bonding aluminium foil has replaced the inner sheath, not only has the protect function of inner sheath, and the hot bonding aluminium foil is inseparabler rather than inside Teflon band 3 subsides moreover, has reduced the diameter of cable to the bend radius of cable has been reduced. In addition, the aluminum foil 4 has a good electronic signal shielding effect, the shielding performance of the cable is improved, and the situation that the braided wire punctures the inner sheath is avoided.

In one embodiment, a woven layer 7 is arranged on the outer side of the thermal bonding aluminum foil, and the woven layer 7 is formed by weaving tinned copper wires. The braid 7 mainly serves as a shield.

In one embodiment, the outer sheath 1 is provided outside the braid 7. The outer sheath 1 mainly serves to protect the inside of the cable.

In one embodiment, the diameter of the towline cable is reduced by at least 12% compared to a cable with a non-woven fabric wrapping and inner jacket structure. The Teflon tape 3 replaces a non-woven fabric tape in the cable in the prior art, the aluminum foil 4 replaces an inner sheath in the cable in the prior art, and the diameter of the cable is reduced by 12% through the structure. Because the bending radius is determined by the outer diameter of the cable, the bending radius is reduced due to the reduction of the outer diameter of the cable, so that the cable can be used in a narrower space, the application range of the cable is expanded, and the service life of the cable is greatly prolonged.
