By using above-mentioned technical proposal, when electric wire bending, it can make electric wire always in straight line as possible by elastic component layer State, and tensile layer can be bent with the bending of elastic component layer, will not be damaged after bending, and when protective layer can be long Between use, will not be ruptured because of external abrasion.

Further, separation layer is equipped between the insulating layer and elastic component layer.

By using above-mentioned technical proposal, insulating layer can be caused to grind when can prevent elastic component layer from repeatedly bending in this way Damage, to leak electricity.

Further, the elastic component layer is spring, and the spring wraps up separation layer.

By using above-mentioned technical proposal, the elasticity needed for elastic component layer can be met by spring, and spring uses Carry out more convenient safety.

Further, the inner wall of the tensile layer is equipped with smooth layer.

By using above-mentioned technical proposal, due to will produce gap when spring is bent, when restoring, gap can close, And smooth layer can be such that the frictional force between spring reduces, and can prevent spring from clamping tensile layer in this way.

Further, adhesive layer is equipped between the protective layer and tensile layer.

By using above-mentioned technical proposal, can make to be firmly adhered to together between protective layer and tensile layer by adhesive layer.

Further, the protective layer is internally provided with several silicon particles.

By using above-mentioned technical proposal, silicon particle can absorb water, and when electric wire works in humid air, can make electricity Drying is kept inside line, prevents from burning out electric wire.

Further, the adhesive layer is made of waterglass.

By using above-mentioned technical proposal, waterglass has good viscosity, and can also prevent fires, it is ensured that electric wire not by It burns.

Further, the tensile layer is made of rubber.

By using above-mentioned technical proposal, the elasticity of rubber is preferable, and rubber can prevent from being worn.

In conclusion the utility model has the advantages that：

1, the electric wire of bending can be made to be in always the state of straight line as possible by the elasticity of spring, can prevented so for a long time It is worn after bending；

2, electric wire internal fires can be prevented the adhesive layer made of waterglass；

3, this electric wire can be made to have the function of waterproof by the silicon particle inside protective layer.

Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing.

A kind of bending resistant electric wire, as shown in Figure 1, including conductor layer 1, conductor layer 1 is externally provided with insulating layer 2, and conductor layer 1 can incite somebody to action Electric power is transmitted, and insulating layer 2 can prevent from leaking electricity in transmission.

As shown in Figure 1, 2, insulating layer 2 is externally provided with one layer of separation layer 3, and separation layer 3 is equipped with spring 4, and spring 4 is by separation layer 3 wrap up, and when electric wire is bent, since the elasticity of spring 4 can make electric wire always linear state, and separation layer 3 can It prevents when being bent, spring 4 clamps insulating layer 2 to keep insulating layer 2 damaged, to cause to leak electricity.Spring 4 is externally provided with drawing Layer 5 is stretched, tensile layer 5 is made of rubber, since rubber has elasticity, can make tensile layer 5 curved with the bending of spring 4 in this way Folding, and can restore to the original state, and spring 4 is wrapped up, one layer of smooth layer 6, smooth layer 6 are additionally provided on the inner wall of tensile layer 5 It is made of polytetrafluoroethylene (PTFE), due to that can be had the gap when spring 4 is bent, when restoring to the original state, tensile layer 5 may be clamped, this Sample can make it clamp the extremely smooth smooth layer 6 in surface, and the frictional force in this way between spring reduces, and tensile layer 5 can be made automatic It is detached from, will not clamp to damage because of by spring 4.

As shown in Figure 1, 2, adhesive layer 7 is additionally provided with outside tensile layer 5, adhesive layer 7 is equipped with protective layer 8, and adhesive layer 7 is by water glass Glass is made, and can prevent from being burnt within adhesive layer 7 so bad, and the inside of protective layer 8 is in hollow state, is equipped in protective layer 8 Silicon particle 9, silicon particle 9 can absorb water, and prevent water penetration to inside to make the burning of wires.

Specific implementation process：Insulating layer 2 is wrapped up by separation layer 3 first, then spring 4 is sleeved on separation layer 3, it will Tensile layer 5 equipped with smooth layer 6 is attached on spring 4, then protective layer 8 is made to be attached on smooth layer 6 by adhesive layer 7, to Wire protective is got up, when electric wire bending, electric wire can be made always by the elasticity of spring 4 and be in the state of straight line as possible, and protected Silicon particle 9 in layer 8 can sponge the water on surface, and the adhesive layer 7 made of waterglass can also prevent fires, and further protect Electric wire.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but As long as all being protected by Patent Law in the right of the utility model.
