Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of core disclosed in the utility model.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawings
Specific embodiment is described in detail.
As it is shown in figure 1, Fig. 1 is structural representation of the present utility model, including core 1, cable core, sheath
2, braid 3 and outer jacket 4.
Cable core is formed by many core 1 systems of twisting, and when being embodied as, the quantity of cable core is 3.Sheath 2
Being extruded in the periphery of cable core, when being embodied as, sheath 2 is extruded in cable core periphery by neoprene and is formed, by
Without implant and twining package tape between sheath 2 and cable core, directly neoprene is extruded in on cable core,
Rubber can be mounted in the gap of core 1, and such cable is when bearing twisting resistance, and each core will not be sent out
Life is mobile and causes distortion of the cable.Braid 3 is arranged on the periphery of sheath 2, when being embodied as, and braiding
Layer 3 is formed by aramid fiber yarn braiding, and count is not less than 90%.Owing to the tensile strength of aramid fiber yarn is big, energy
Enough improve the tensile strength of cable.Outer jacket 4 is coated on the periphery of braid 3.When being embodied as, protect outward
The periphery that layer 4 is extruded in braid 3 by neoprene material is formed.Owing to the tolerance to cold of neoprene material is good,
Can reach-40 DEG C, tensile strength can reach more than 16.0N/mm2, and tear strength is up to 13.1N/mm,
Oxygen index (OI) can reach 42%, and resistance to saltfog is high, and it is at 90 DEG C, in the aqueous solution containing NaCl 30g/L, and experience
672 hours, its tensile strength and elongation at break did not had bigger change compared with initial condition.So, energy
