Bending-resistant cable for industrial robot demonstrator

Abstract

The invention relates to a robot cable, specifically to a bending-resistant cable for an industrial robot demonstrator, and belongs to the technical field of robot cables. The bending-resistant cable comprises an outer sheath layer and a general shielding layer, wherein a signal line, a first power line, a second power line and a third power line, which are mutually independent, are arranged in the general shield layer, the outer sheath layer is arranged on the outer surface of the general shielding layer, and the gaps between the signal line, the first power line, the second power line and the third power line in the general shield inner cavity are filled with a filling layer. The bending-resistant cable employs the independent structure of separating the signal line from the power lines, the signal line is shielded individually, and an inner sheath is added to ensure the stability of the structure. The signal line conductor layer employs a core twisted-pair short pitch and 100% back twist, and the internal stress between the cores is released. The internal structure may not change, even if the bending-resistant cable is subjected to the impact of external forces.

Description

technical field [0001] The invention relates to a robot cable, in particular to a bending-resistant cable for an industrial robot teaching device, which belongs to the technical field of robot cables. Background technique [0002] Because the industrial robot teach pendant cable needs to transmit communication signals during use, and there are situations such as mopping the floor, rolling, and dragging during use, the difficulty of this product is to take into account these two performances. Currently After the products on the market have been used for a period of time, due to the dragging and rolling during use, the internal structure of the wire will be deformed and the wire will be broken or the transmission signal will be distorted. The imported cables are all compatible with the robot teach pendant. The cost of supporting sales is very high, which is not conducive to the development of my country's independent research and development of robots. my country currently needs...

[0002] Because the industrial robot teach pendant cable needs to transmit communication signals during use, and there are situations such as mopping the floor, rolling, and dragging during use, the difficulty of this product is to take into account these two performances. Currently After the products on the market have been used for a period of time, due to the dragging and rolling during use, the internal structure of the wire will be deformed and the wire will be broken or the transmission signal will be distorted. The imported cables are all compatible with the robot teach pendant. The cost of supporting sales is very high, which is not conducive to the development of my country's independent research and development of robots. my country currently needs its own robot control system with independent intellectual property rights, so it needs to independently develop teaching devices.
