Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Example one
Referring to fig. 1, the utility model discloses a robot dynamic transmission cable, including signal transmission unit 1, first around covering 2, shielding layer 3, second around covering 4 and oversheath layer 5. The signal transmission unit 1 includes conductor 11 and insulating layer 12, the insulating layer 12 cladding conductor 11, in this embodiment, conductor 11 comprises the transposition of stranded hyperfine copper wire, makes conductor 11 possesses certain intensity when possessing higher compliance, and difficult broken string, the robot still can stably transmit visual signal and provide the assurance at the in-process of motion. The insulating layer 12 is made of polyethylene, and due to the nonpolarity of polyethylene, the polyethylene has excellent electrical properties of low dielectric loss and high dielectric strength, so that the stability of signal transmission is better, and meanwhile, due to the good impact resistance of polyethylene, the flexibility of a cable is realized while signals are transmitted, and the polyethylene can adapt to a long-stroke drag chain and the like without affecting the transmission of signals. In this embodiment, the signal transmission units 1 in the cable generally include three and are arranged in an array with reference to the center of the cable.
