Background

The industrial robot industry is an important component of the high-end equipment manufacturing industry.

China will become the largest industrial robot consuming country in the world by 2014. By 2015, the demand of the Chinese robot market is estimated to reach 3.5 thousands of robots, which account for 16.9% of the total global quantity and become the largest robot market in scale. The experts show that the market of the Chinese industrial robot can be compositely accelerated by 30 percent in the future 3 years, and the explosive growth can be realized. And a high-performance signal transmission cable has important significance for the development of robots or new energy vehicles, so that a high-performance signal cable is developed.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the high-performance signal cable with wear resistance, flexibility, high strength and excellent weather resistance is provided.

In order to achieve the purpose, the utility model provides a high-performance signal cable, including fan-shaped support of bending, the structure of fan-shaped support of bending be the connector in the middle part, connect a plurality of arc angles as an organic whole structure with the connector on this connector, the angle point of arc angle is the fillet, the radian is 30 ~ 60 degrees, form an open type cavity between two adjacent arc angles, open at least one fiber channel on the connector, along this fan-shaped support of bending outward flange extrusion package polyurethane protection layer, be equipped with behind the insulating core in the open type cavity and around the fan-shaped support of bending wind band of binding, the opening size of open type cavity is less than the external diameter of insulating core, the fiber channel in be equipped with optic fibre, the binding be equipped with behind the outer aluminium-plastic composite band of band again weaving copper wire and constitute double shielding layer, extrude the cladding TPU oversheath outside double shielding layer.

Preferably, the fan-shaped bent bracket is made of nylon, PE or PU light materials.

Preferably, the optical fiber is a glass optical fiber or a plastic optical fiber.

Preferably, the insulated wire core is composed of a copper conductor and a polyethylene insulating layer extruded outside the copper conductor.

Preferably, the fastening tape is a polyester tape or a nonwoven fabric.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the bracket is arranged, when the core wire moves, the bracket can play a role of a spine, bear the stress caused by the movement and reduce the damage of the core wire caused by the movement stress; when the whole product is subjected to external force, the bending angle of the bracket can play a role in resisting pushing force and offsetting a part of external force; the bend angle is also equivalent to an open round-corner hollow tube, not only can the core wire be fixed, but also the core wire can generate torsion when the product is integrally twisted, and the round-corner hollow tube can ensure that the core wire rotates forwards and backwards in the tube to release the torsion; compared with the traditional bracket, the single side is in a V shape, the core wire is in the V shape, when the core wire is extruded by external force in production, the core wire can be extruded into the V shape, the core wire cannot rotate, and the insulating layer of the core wire can be extruded to cause certain damage to the insulating layer; meanwhile, the sharp corners of the V-shaped structure can damage the outer layer, such as a wrapping tape, a shielding layer and even a sheath layer.

2. A layer of soft, smooth and high-strength PU or similar performance material is extruded out of the outer layer of the bracket, so that the protection on the bracket body is increased, and the core wire twisting and the friction generated by the bracket wall are reduced. The strength and the service life of the bracket are improved.

3. The support effect is used for injecing the position of signal line around, and stable signal transmission reduces vibrations, increases the safety in utilization of optic fibre, increases the tow chain performance of whole signal line, increases the whole life of product.

4. This cable structure has solved the signal line and in removing the use, when solving and removing, can also guarantee signal transmission performance, still increases optic fibre performance, has improved wearability, pliability, intensity height, excellent weatherability, to ozone, ultraviolet ray, intensity height, low temperature resistance performance, high environmental protection performance, the weight is heavy, the pliability is good, is favorable to new energy automobile and robot long-term development to be used.
