Move with the soft flat cable of tension
Technical field:
The utility model relates to a kind of mobile with the soft flat cable of tension, belongs to technical field of electric wires and cables.
Background technology:
Driving, crane and in tansport equipment, cable provides power and signal controlling operation for equipment, this type of cable performance requires high, structure is comparatively complicated, and its cross section generally can be flat, at present, there is following defective in the employed power cable of this kind equipment: because cable in use not only will bear the gravity of self, but also to bear the pulling force that moves back and forth and produced from equipment, and therefore cause the core of cable to fracture easily, cause and scrap; Also have, cable in use needs frequently to move, and produces slippage between the core of cable and the sheath, and insulated wire cores is stretched out outside the sheath, and insulation is stretched, and when heavy current was passed through, cable was breakdown easily.And this present class cable is soft inadequately, and flexibility is little, and stretching resistance is little, and conductor ruptures easily, in use if cable breaks down and often causes the generation of production accident, and present removal cable not fire-retardant, cigarette, poisonous not environmental protection arranged.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide that a kind of mobile this cable has higher pliability with the soft flat cable of tension, and stronger tensile property bends repeatedly that conductor does not rupture, insulation and sheath chap line not.
The utility model technical solution problem adopts following technical scheme:
Move with the soft flat cable of tension, the oversheath that cross section is a flat is set, middle part in described oversheath be arranged in parallel and at least three thoroughly does away with the edge cores, each insulated wire cores is made of conductor, the insulating barrier and the wrapped belting layer outside insulating barrier that extrude outside conductor respectively, and is positioned at three both sides of thoroughly doing away with the edge cores is respectively arranged with the tension bowden cable in described oversheath.
Described conductor adopts the special soft tin-coated copper core flexible conductor of the 6th class.
Described oversheath adopts thermoplastic halogen-free and low-smoke highly fire-proof elastic body material.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Cable conductor is compact pliable and tough, and easy fracture is not anti-oxidant.Promptly this cable has higher pliability, is flexible about 10 times of general cable; Insulating barrier and oversheath have excellent weather resisteant, heat-resistant aging, excellent tensile strength, toughness, resilience and excellent compression set, good electrical insulation properties and low smoke, zero halogen high flame resistance, simultaneously insulating barrier, oversheath chap line not also; Both sides in oversheath are provided with two more fine and soft stone dead wire ropes (single diameter is not more than 0.8mm), make its characteristic with tension, and its tensile strength can reach 800Mpa, thus guarantee oversheath and conductor do not rupture, indeformable, and operation safely.The utility model cable softness, tension, fire-retardant, the power cable that has solved driving, mobile transporting equipment is inadequately soft, flexibility is little, stretching resistance is little, conductor ruptures easily, the problem of oxidation, makes it can be widely used in control line between input of the main power source of tansport equipment and control system such as various gantry, bridge-type, beam type, floor rail type driving and building materials, metallurgy etc.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 conductor, 2 insulating barriers, 3 belting layers, 4 hawsers, 5 oversheaths.
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: shown in Figure 1, conductor 1 adopts the special soft tin-coated copper core flexible conductor of the 6th class, conductor production through wire drawing-annealing zinc-plated-synnema-(multiple strand) four-stage, the form that conductor adopts bundle to twist, the cross section is at 4mm
2Following conductor adopts the synnema form, and the cross section is at 4mm
2And above conductor, because the cross section is big, conductor monofilament radical is too many, also will carry out multiple strand, wherein 4mm behind synnema
2With monofilament maximum gauge in the lower conductor is 0.16mm, 6-35mm
2The monofilament maximum gauge is 0.21mm in the conductor, 50-150mm
2The monofilament maximum gauge is 0.31mm in the conductor, 185mm
2Reaching with monofilament maximum gauge in the upper conductor is 0.41mm, simultaneously 2.5mm
2Below adopt fine pith synnema, 2.5mm
2And it is stranded in the other direction behind the above first fine pith synnema; Insulating barrier 2 adopts the thermoplastic halogen-free and low-smoke flame-retardant ethylene propylene rubber insulation material, adopts plsitive mold to extrude, and temperature is controlled between 145 ± 10 ℃; Belting layer 3 is that nonwoven fabrics is wrapped, and employing is put up wrapped, puts up rate 20%; Tension hawser 4 adopts two thin (single diameter is not more than 0.8mm) soft tension hawsers, and the both sides that are embedded in oversheath 5 are the radial symmetric setting; The periphery of tension hawser 4 is provided with restrictive coating, and the oversheath 5 of this restrictive coating and cable forms integrative-structure.By the oversheath 5 of thermoplastic halogen-free and low-smoke highly fire-proof elastic body material, equally also adopt plsitive mold to extrude, temperature is controlled between 120~150 ℃, can adjust mould according to the actual conditions of equipment and material.
