Abstract
The utility model discloses a bear formula flat cable, including a plurality of cable cores, two piece at least high strength flexible cables and oversheath, the cable core sets up in the oversheath and leans on the intermediate position, and the high strength flexible cable sets up in the inside both sides position of leaning on of oversheath, and the cable core sets up with high strength flexible cable flat raft interval and the high strength flexible cable sets up in the cable core both sides, the crowded package of oversheath in the whole outside that cable core and high strength flexible cable are constituteed, the high strength flexible cable directly twists the shaping than, stranded by the small -ga(u)ge wire with the small matter again. This cable is applicable to with special construction design, can install at the track as power and control cable, the hoist, occasions such as commodity circulation transport, the continuous core of conductor of operation in -process cable, insulating not damaged or and the cable core indeformable, thereby make cable safety, reliability service, extension cable life protects electrical equipment's safe operation simultaneously effectively.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of bearing-type flat cable.
Background technology
Track installation, crane, the demand of the electrical connections of electric equipment such as handling and conveying class and the flat cable of control gets more and more, and requires also more and more higher to its environment for use, particularly constantly increase the flat electric power of load bearing requirements and the demand of control cables, performance requirement is corresponding raising also.
At present, market uses many flat cables, but substantially can not meet load bearing requirements, at work service requirement cable, thisly back and forth stretching continually, in the process that circumnutates, cable will occur that conductor breaks core, damage in insulation, a cage and cable core and sheath interlaminar separation and to make insulated wire cores or cable core report to the leadship after accomplishing a task out of order; It is shorter for useful life that operation installed by final cable often, just do not break down to scheduled time cable and scrap.Occur that the main cause of above-mentioned phenomenon is:
1) cable does not possess the flexible structure of high strength, and its carrying main body is the conductor of cable, insulation and sheath substantially, and these three main body Dan Yuan are for this type of use occasion, flexible not enough, insufficient strength.
2) muscle is not had between the insulated wire cores of cable or cable core, to the insulated wire cores of cable or cable core and sheath interlaminar separation be there is in cable in running, insulated wire cores or cable core is caused to be reported to the leadship after accomplishing a task out of order, the core of original cable and cable core queueing discipline are upset, there is the phenomenons such as distortion of the cable, loose and fracture, this construction of cable is single, relatively this occasion, hot strength and crimp property inadequate.
Summary of the invention
Goal of the invention: the purpose of this utility model be to solve existing cable certainly by the flexible structure of high strength, do not have a muscle to arrange and the problem of the phenomenons such as distortion of the cable, loose and fracture can be caused.
Technical scheme: the utility model provides following technical scheme: a kind of bearing-type flat cable, comprise some cable cores, at least two high-strength flexible cable wires and oversheath, described cable core is arranged at oversheath by centre position, high-strength flexible cable wire is arranged at oversheath inside by two side positions, cable core and high-strength flexible cable wire flat raft interval arranges and high-strength flexible cable wire is arranged at cable core both sides, oversheath extrudes the integral outer in cable core and high-strength flexible cable wire composition, and described high-strength flexible cable wire is twisted into type by finer wire again with little lay ratio, multiply.
As optimization, described cable core is made up of the outer extruded insulation layer of conductor, its stranding lay ratio ≯ 12.
As optimization, described high-strength flexible cable wire is twisted into type by finer wire again with little lay ratio, multiply, its lay ratio ≯ 8.
As optimization, described high-strength flexible cable wire and cable core flat raft interval are arranged, and spacing distance is 1 ~ 5mm.
As optimization, described every root cable core with between high-strength flexible cable wire all by between muscle connect.
As optimization, described conductor is once bundle strand conductor/multiple stranded conductor, once bundle strand its lay ratio ≯ 14 of conductor, and the bundle of multiple stranded conductor closes lay ratio ≯ 18, stranded lay ratio internal layer ≯ 11, outer ≯ 9.
Beneficial effect: the utility model is relative to prior art: the utility model adopts high-strength flexible cable wire to be twisted into the design of type again with little lay ratio, multiply by finer wire, substitute the original scheme such as finer wire, stone dead wire, the cable wire load being is higher, and bending property is better, simultaneously, every root cable core with between high-strength flexible cable wire all by between muscle connect, make, in running the continuous core of the conductor of cable, insulation not damaged or and cable core indeformable.The utility model is particularly useful for, with special construction design, can be used as power and control cables is arranged on track, crane, the occasions such as handling and conveying; Thus make cable security, reliability service, extend cable useful life, simultaneously the safe operation of protective device equipment effectively.
