Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of high flexibility rail traffic vehicles power supply electricity
Cable, including inner support layer 1, inner support layer 1, support bar 12 and outer support layer 13 are made of poly- third fat rubber, can increased
Flexibility, and good heat dissipation effect, the inside of inner support layer 1 are provided with cavity 11, the outer surface of inner support layer 1 is fixedly connected with support
Bar 12, the width of support bar 12 is three millimeters to five millimeters, and spacing is ten centimetres and is uniformly distributed, and so can both have been played certain
Supporting role, cable bend will not be hindered again, for adaptability than wide, the outer surface of support bar 12 is fixedly connected with outer support
Layer 13, the outer surface of outer support layer 13 is provided with anticollision projection 14, and anticollision projection 14 is equally distributed in the appearance of outer support layer 13
Face, and spacing is not less than the width of anticollision projection 14, the outer surface of anticollision projection 14 is provided with lozenges 15, so can be anticollision
The junction of projection 14 is smaller, reserves the space of compression, can effectively reduce shock dynamics, improves security, support bar
