Example (b): referring to fig. 1, a withstand voltage power cord, including inner core 1, the outside of inner core 1 evenly is provided with outer core 2 that a plurality of circumferences set up, the outside that inner core 1 was kept away from to a plurality of outer core 2 all is provided with even atress layer 3, even atress layer 3 can be any one among the prior art, for example, the higher outer silica gel layer of hardness, two groove 10 of dodging have been seted up to the lateral part of even atress layer 3, through the setting of dodging groove 10, can dodge, from not influencing each even atress layer 3 and remove, even atress layer 3 is connected with inner core 1 through elastic telescoping mechanism, a plurality of even atress layer 3 externally mounted have outer 4, the wearing layer is installed to outer 4's outside portion, the wearing layer can be any one among the prior art, for example, the rubber layer, setting through the wearing layer, can improve the wearability.

Two first elastic pulling layers 8 are all installed at the lateral part of any one outer layer core 2, any one outer layer core 2 is connected with the inner layer core 1 through a second elastic pulling layer 9, the first elastic pulling layer 8 and the second elastic pulling layer 9 can be any elastic structure in the prior art, the two first elastic pulling layers 8 are symmetrically arranged based on the second elastic pulling layer 9, and one ends, far away from the outer layer core 2, of the two first elastic pulling layers 8 are respectively installed on the two elastic telescopic mechanisms.

Borrow by above-mentioned structure, through the setting of even atress layer 3, can change the single department atress into whole atress, avoid the too big direct damage that causes of certain department atress, setting through first elasticity pulling layer 8 and second elasticity pulling layer 9, when even atress layer 3 atress removes, make two first elasticity pulling layer 8 length that are close to rather than mutually shorten, thereby make the pulling force diminish, two first elasticity pulling layers 8 and two second elasticity pulling layers 9's of keeping away from articulamentum 5 pressure correspondingly diminish, and then will be located articulamentum 5 both sides outer core 2 and drag away, thereby dodge, prevent that two outer cores 2 from being extruded by even atress layer 3, thereby improve the resistance to pressure, further protect outer core 2.

In this embodiment, as shown in fig. 2, the elastic telescopic mechanism includes a sliding layer 6, a connection layer 5 and an elastic buffer layer 7, the sliding layer and the connection layer 5 may be made of a silica gel material with a relatively high hardness, the elastic buffer layer 7 may be made of any elastic material in the prior art, the sliding layer 6 is slidably mounted in the connection layer 5, a side portion of the sliding layer 6 away from the inner core 1 is connected to a side portion of the elastic buffer layer 7, another side portion of the elastic buffer layer 7 is connected to the uniform stress layer 3, a side portion of the sliding layer 6 away from the connection layer 5 is connected to a side portion of the inner core 1, a side portion of the connection layer 5 away from the sliding layer 6 is connected to a side portion of the uniform stress layer 3, and the first elastic pulling layer 8 is mounted on a side portion of the connection layer 5. Through the setting of elasticity telescopic machanism, can make to have certain elastic force between inlayer core 1 and the inlayer core 1 to can keep the position of inlayer core 1.

In this embodiment, referring back to fig. 1, an outer filling layer 11 and an inner filling layer 12 are disposed in the outer layer 4, the outer filling layer 11 is located in a space formed by the outer core 2, the first elastic pulling layer 8 and the uniform stress layer 3, and the inner filling layer 12 is located in a space formed by the inner core 1, the outer core 2, the second elastic pulling layer 9, the connecting layer 5, the sliding layer 6 and the first elastic pulling layer 8.
