Abstract
The utility model relates to a sheath for cables, particularly a metallic sheath, belonging to the field of protective sheathes. The utility model is characterized in that the metallic sheath is a stainless steel tube welded with thin stainless steel strips, and the surface of the stainless steel is rolled with screw threads. The utility model has the advantages of fine bendability, high temperature resistance, radiation protection and favorable effect of shielding, so that the cable of the utility model can endure large pressure. The utility model is suitable for various cables and optical cables, such as aerial cables, straight embedding cables, underwater cables, lightning protected cables, shielded cables, fire prevention cables, etc., with long service life.
Description
A kind of cable, optical cable metal-coating, it relates to protective jacket field, particularly cable, optical cable metallic jacket.
Present existing cable jacket mainly is by vinyon or igelite manufacturing, also useful rubber manufacturing.Though this class cable jacket has suitable pliability, exists following shortcoming: the one, mechanical strength is low, damages easily; The 2nd, easy firing, non-refractory; The 3rd, easy season cracking, useful life is short.If adopt common metal to do oversheath, metal big city rots until corrosion in air or water oxygenization.A kind of oversheath of three-decker has appearred in prior art, the oversheath of this three-decker be by wet-strong paper, metal coil tape around together, constitute cable jacket.This cable jacket cost is higher, and difficulty of processing is big.
The purpose of this utility model is to provide a kind of saving material, and is simple in structure, has good usability again, cable, optical cable metallic jacket that the life-span is longer.
The purpose of this utility model is achieved in that
A kind of cable, optical cable metallic jacket. it is characterized in that it is the stainless steel tube 3 that is welded into by slim stainless steel band, screw thread 4 arranged in that the outer surface of described stainless steel tube 3 is rolling.The pipe thickness of stainless steel tube 3 is 0.2～0.5 millimeter.
The utility model intensity height, anti-aging, long service life, and have high temperature resistant, corrosion-resistant, radiation hardness, hermetically sealed, fire prevention, anti-lightning strike, anti-interference, the anti-plague of rats, premium properties such as termite-proof.Rolled threaded on the utility model, the stainless steel tube bending radius is significantly reduced, make cable can bending freely, also increased radial crushing strength simultaneously, make cable can bear bigger pressure.
Accompanying drawing 1 is a user mode structural representation of the present utility model;
Accompanying drawing 2 is the left view of accompanying drawing 1.
Following attached Fig. 1 and 2 is embodiment of the present utility model, and the utility model is further specified:
Adopt slim stainless steel band to be welded into stainless steel tube 3, guaranteed the utlity model has good sealing property and higher mechanical strength.Rolled threaded 4 at the outer surface of described stainless steel tube 3, its purpose is exactly the bending radius that will reduce stainless steel tube 3, makes stainless steel tube 3 have better pliability, with guarantee cable can bending freely.Use the material of stainless steel, make increase greatly the useful life of cable, relatively reduced the cost of cable as oversheath.When using the utility model, at first inner sheath 2 on cable core 1 outer wrapping of cable puts the utility model again and gets final product outside inner sheath 2.The utility model is applicable to various cables and optical cables such as aerial cable, direct-buried cable, submerged cable, lightning protected cable, shielded type cable, fireproof cable.Pipe thickness of the present utility model should increase along with the increase of caliber, but the blocked up not only waste material of tube wall also can make cable become heavy, and therefore thickness of pipe wall of the present utility model generally should be controlled at 0.2～0.5 millimeter.
Claims (2)
1, a kind of cable, optical cable metallic jacket is characterized in that it is the stainless steel tube (3) that is welded into by slim stainless steel band, screw thread (4) are arranged in that the outer surface of described stainless steel tube (3) is rolling.
2, the cable described in claim 1, optical cable metallic jacket, the thickness of pipe wall that it is characterized in that described stainless steel tube 3 is 0.2～0.5 millimeter.
