Abstract

The utility model discloses a steel supporting, moving and connecting flexible cable for a communication vehicle. The flexible cable comprises a cable core and a head shielding layer arranged on an outer layer of the cable core, wherein the head shielding layer is provided with an outer sheath; the cable core is formed by twisting a ground wire, a video cable, a plurality of signal cables and a power cable; a clearance of the cable core is filled with filling fiber to maintain the roundness of the cable; and a steel wire rope is arranged at the center of the cable core. The flexible cable can integrate the functions of power supply and signal and video transmission, has the characteristics of high temperature resistance, low temperature resistance, weather resistance, ozone resistance, ultraviolet ray resistance and flexible tension, and is suitable for complex outdoor environment.

Description

The communication truck steel supports to move and connects flexible cable

Technical field:

The utility model relates to a kind of communication truck steel and supports the mobile flexible cable that connects, and belongs to technical field of electric wires and cables.

Background technology:

When communication truck field work, the part mobile unit need be taken out of the local work with a certain distance from communication truck, as antenna, radar etc., wiring and take-up require certain ageing again, so the outside diameter of cable is the smaller the better, and cable weight is light more good more, to reduce workload, increase work efficiency.Separately wiring of each cable in the past, waste time and energy, and field work circumstance complication, weatherability to cable has requirement again, factors such as high temperature, low temperature, ozone, ultraviolet ray are also influential, pull and certain self-supporting requirement because cable is frequent, also requiring has certain anti-pulling force and flexibility, and former cable can not well satisfy these requirements.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide the supply of a kind of current collection source, signal and screen transfer function are one, and have high temperature resistant, low temperature resistant, weatherability, anti-ozone and ultraviolet ray, comprehensive cable soft tension, that be applicable to complicated wild environment.

The utility model technical solution problem adopts following technical scheme:

The utility model communication truck steel supports to move and connects pair twist signal cable, video line, power cable, the ground wire formation cable conductor of flexible cable with the coated insulation layer, with this cable core is the center, form total screen and external sheath layer from inside to outside successively in its periphery, be filled with the fiberfill fibers that adapts with insulating material in the gap of cable conductor to keep the roundness of cable.

Design feature of the present utility model is that the conductor of pair twist signal cable, video line, power cable, ground wire adopts the soft junction structure of many tinned copper wires, the fluoroplastics of the title that " plastics king " arranged are adopted in the insulation of pair twist signal cable, video line, power cable, ground wire, the braiding sub-shield that the pair twist signal cable externally has tinned copper wire to constitute is with anti-tampering.The steel cable that pulls usefulness is placed by central authorities at cable conductor, and the external sheath layer of cable adopts elastomeric material.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the soft junction structure of many tinned copper wires of the conductor of each pair twist signal cable, video line, power cable, ground wire employing in the cable conductor of the present utility model has guaranteed softness and bending property that this cable is good.

2, each pair twist signal cable in the cable conductor of the present utility model, video line, power cable, the fluoroplastics of the title that " plastics king " arranged are adopted in the ground wire insulation, the scope of its working temperature can reach-60 ℃～200 ℃, good high temperature resistant and cryogenic property is arranged, and fluoroplastics have than the better mechanical performance of other plastics, higher insulation resistance and less dielectric loss, can effectively reduce the thickness of the insulating barrier of each assembled unit, be embodied on the utility model, can reduce the external diameter and the weight that alleviates cable of cable effectively, bring convenience for wiring and take-up, fluoroplastics also have good weatherability simultaneously, anti-ozone and ultraviolet performance.

3, place steel cable in the cable conductor of the present utility model, stronger stretching resistance is arranged, when the wiring of cable and take-up, can effectively reduce and pull the damage that cable is brought, when the equipment that is connected to eminence freely hangs, can effectively share the deadweight of cable, can effectively prolong the life-span of cable.

4, all there is own sub-shield the unit of transmission weak electric signal in the cable conductor of the present utility model, can effectively prevent the stop element external disturbance, and the raising signal transfer quality makes the more reliable performance of this cable.

5, cable conductor of the present utility model also has the total screen of one deck outward, with the interference that prevents that vehicle power and its connection device from bringing, has improved the overall electrical property of this cable.

6, oversheath of the present utility model adopts elastomeric material, than common rubber and rubber better softness is arranged, its better elastic can effectively cushion the exterior mechanical impulsive force of cable, and have good oil resistant, high temperature resistant, low temperature resistant, weatherability, anti-ozone and ultraviolet performance, its overall soft effect, also have certain anti-twisting property, can on equipment that reverses such as radar, stably work.

7, the performance that the utility model each side is good and its soft effect can adapt to the field work environment of various complexity, even in the sizable desert area of the temperature difference, still can stably work.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Number in the figure: 1 ground wire, 2 video lines, 3 total screens, 4 signal cables, 5 power cables, 6 oversheaths, 7 steel wire ropes, 8 sub-shields, 9 fiberfill fibers.

Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

Embodiment, non-limiting examples is as described below:

Embodiment: referring to accompanying drawing: the conductor of ground wire 1 is made up of the multiply tinned copper wire of bundle strand, and its periphery is the insulating barrier that closely extrudes, and insulating layer material is fluoroplastics; The conductor of video line 2 is made up of the multiply tinned copper wire of bundle strand, and its periphery is the fluoroplastic insulation layer that closely extrudes; Total screen 3 is a tincopper fuse wire braided armor; The conductor of pair twist signal cable 4 is the multiply tinned copper wire, insulate to be the fluoroplastics that closely extrude, and four pair twist signal cables are twisted into quad again, and each the pair twist cable twisting pitch in the quad has nothing in common with each other, to prevent cross-talk.Quad has one deck tinned copper wire sub-shield 8 outward, to prevent external disturbance.The conductor of power cable 5 is made up of the multiply tinned copper wire of bundle strand, and its periphery is the insulating barrier that closely extrudes, and its material is fluoroplastics; Oversheath 6 is an elastomeric material, has good oil resistant, high temperature resistant, low temperature resistant, weatherability, anti-ozone and ultraviolet performance and flexibility thereof.Steel wire rope 7 can effectively increase cable tensile property and load-bearing property, and steel wire rope is arranged on the center of cable conductor.Be filled with the fiberfill fibers 9 that adapts with insulating material in the gap of cable conductor to keep the roundness of cable.
