Problems solved by technology

[0002] my country's industrial robots are still in their infancy. The quality of their accessories on the market is uneven, and the same is true for cables. At present, most of the cables used by industrial robots are ordinary PVC insulated and PVC sheathed cables, and the processing technology is the same as ordinary cables. , this kind of cable generally does not have the conditions for mobile installation, the wire is hard, not easy to lay, and the elasticity is extremely poor
However, the working conditions of industrial robots are very complicated, and ordinary cables cannot meet their use requirements, resulting in disconnection during use, which brings risks and losses to customers

Embodiment 1

[0021] Example 1, such as Figure 1-4 Shown:

[0022] A bending-resistant and twist-resistant cable, comprising: a wire 1, a shielding layer and an outer sheath, the wire 1 is formed by twisting more than three wires 11, and the wire 11 is twisted by more than two wires 111 and The outer layer is covered with an inner sheath; the wire 111 is composed of a conductor 1112 and an insulating layer 1111 covered by an outer layer; the outer layer of the wire 1 is covered with a shielding layer, and the outer layer of the shielding layer is covered with outer sheath.

[0023] In this implementation, the outer sheath is made of 125°C halogen-free flame-retardant thermoplastic polyurethane elastomer material, which has the comprehensive properties of vulcanized rubber and general thermoplastic materials. Its outstanding advantages are high strength, high elasticity, wear resistance, weather resistance, radiation resistance, oil resistance, softness (especially softness at low tempera...

Embodiment 2

[0027] Example 2, such as Figure 5 Shown:

[0028] On the basis of Embodiment 1, there is a teflon filler between the wire 1 and the shielding layer, the wire 11 and the inner sheath, which can effectively share the tension of the cable on the core wire during movement.

Abstract

The invention provides a bending-resistant anti-torsion cable, and the cable comprises a wire 1, a shielding layer, and an external sheath. The wire 1 is formed by the twisting of three or more conductors 11, and each conductor 11 is formed by that two or more conductors 111 are twisted and then are wrapped by an internal sheath. Each conductor 111 consists of a conductor 1112 and an insulating layer 1111 wrapping the outer layer. The outer layer of the wire 1 is wrapped by the shielding layer, and the outer layer of the shielding layer is wrapped by the external sheath. The cable is reasonable in structure, is excellent in performance, and is excellent in shielding rate and resistance to bending and torsion. The number of bending and torsion times of the cable can be greater than 80,000,000, and the cable is a dedicated cable for an industrial robot system.

Description

technical field [0001] The invention relates to a cable, in particular to a bending-resistant and torsion-resistant cable. Background technique [0002] my country's industrial robots are still in their infancy. The quality of their accessories on the market is uneven, and the same is true for cables. At present, most of the cables used by industrial robots are ordinary PVC insulated and PVC sheathed cables, and the processing technology is the same as ordinary cables. , This kind of cable generally does not have the conditions for mobile installation, the wire is hard, not easy to lay, and the elasticity is extremely poor. However, the working conditions of industrial robots are very complicated, and ordinary cables cannot meet their use requirements, resulting in disconnection during use, which brings risks and losses to customers. [0003] The cable can meet the bending and torsion resistance of more than 80 million times without cable deformation and conductor breakage. ...
