Description

A kind of control cable

Technical field

The utility model relates to field of cable technology more particularly to a kind of control cables.

Background technique

With economic sustainable development, demand of the people to traffic is growing day by day, the substantial increase of motor vehicle and Che Jundao The reduction of road surface product produces the problems such as traffic congestion, running speed decline and environmental pollution in city, faces day The beneficial severe fact, China gradually adjust Urban Traffic Development Strategy, start the large capacities rail rapid transits such as construction subway and are Main modernization integrated transport system, and existing cable industry, especially control are easily damaged situations such as breaking with cable, use Period is short, increases use cost.

Utility model content

The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of control cable.

The utility model is achieved through the following technical solutions:

A kind of control cable, includes cable core, and the cable core includes round rubber skeleton, support frame, sickle Skeleton, the first core, the second core and third core are respectively fixedly connected with and rubber bone in the outside surrounding of round rubber skeleton The vertical support frame of frame, the other end of each support frame are respectively fixedly connected with the middle position of four sickle skeletons, The first core is equipped on the inside of round rubber skeleton, first core, which includes the first conductor and is successively coated on first, leads The fluoroplastic insulation layer of external side, outside are coated with the Mica tape layer and LWA light wire armoured layer of magnesium oxide coating, in each sickle The left and right sides for being located at support frame on the inside of blade type skeleton is respectively equipped with the second core and third core, and second core includes There is the second conductor, ethylene propylene diene rubber insulating layer and high temperature resistance glass fiber the band wrapping layer being successively coated on the outside of the second conductor, It being coated with multi-layered polyester Transposed wind layer after two second conductor pair twists, the third core includes third conductor, It is successively coated with polyolefin insulation layer and glass cotton cord winding layer on the outside of third conductor, is successively coated on the outside of the cable core Polyether-ether-ketone protective layer, silver-coated copper wire woven shield, Tarpauling wrapping layer, metal sheath and environmental-friendly halogen-free low-smoke Flame-Retardant and Oil-Resistant EVM rubber sheath.

First conductor, the second conductor and the third conductor is by high strength fibre rope and multiply tinned wird bundle strand Made of.

It is equipped with elastic polyurethane partition between every two adjacent sickle skeleton, prevents the second core and third core Between position change.

The utility model has the advantages that: the utility model uses circular framework, and the first core is arranged in a circular framework, The first core is protected well, is surrounded by support frame and sickle skeleton, support frame and reaping hook on the outside of circular framework The cooperation of type skeleton constitutes umbrella shape, protects the second core and third core well, the cooperation of three skeletons increases cable Compressive property, not easy to break, internal structure is unlikely to deform, and weight is small, long service life, does not have to often replacement, and signal transmission is steady It is fixed safe and reliable；It is wrapped that polyether-ether-ketone protective layer, silver-coated copper wire woven shield, Tarpauling are successively coated on the outside of cable core Layer, metal sheath and resistant environmental low-smoke halogen-free flame oil resistant EVM rubber sheath, increase the waterproof effect of cable, and lead closes Golden inner sheath guarantees that cable core conductor is invaded from moisture water-wet, also functions to etch-proof effect, environmental-friendly halogen-free low-smoke resistance It is good to fire oil resistant EVM rubber sheath environment protecting, it is light-weight, it is soft.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, a kind of control cable, includes cable core, the cable core includes round rubber skeleton 1, support Skeleton 2, sickle skeleton 3, the first core, the second core and third core, it is solid respectively in the outside surrounding of round rubber skeleton 1 The fixed connection support frame 2 vertical with rubber skeleton, the other end of each support frame 2 are respectively fixedly connected with four sickle bones The middle position of frame 3, is equipped with the first core on the inside of round rubber skeleton 1, first core include the first conductor 4 with And be successively coated on the fluoroplastic insulation layer 5 in the outside of the first conductor 4, outside is coated with 6 and of Mica tape layer of magnesium oxide coating LWA light wire armoured layer 7, the left and right sides on the inside of each sickle skeleton 3 positioned at support frame 2 are respectively equipped with the second core and the Three cores, second core include the second conductor 8, in the ethylene propylene diene rubber that 8 outside of the second conductor is successively coated with Insulating layer 9 and high temperature resistance glass fiber band wrapping layer 10, will be coated with multi-layered polyester Transposed wind layer after two second conductor, 8 pair twists 11, the third core includes third conductor 12, is successively coated with 13 He of polyolefin insulation layer in 12 outside of third conductor Glass cotton cord winding layer 14 is successively coated with polyether-ether-ketone protective layer 15, silver-coated copper wire braid shielded on the outside of the cable core Layer 16, Tarpauling wrapping layer 17, metal sheath 18 and resistant environmental low-smoke halogen-free flame oil resistant EVM rubber sheath 19.

First conductor 4, the second conductor 8 and the third conductor 12 is by high strength fibre rope and multiply tinned wird Made of bundle strand.

It is equipped with elastic polyurethane partition 20 between every two adjacent sickle skeleton 3, prevents the second core and third Position between core changes.
