The flat cable of the utility model is advantaged by strong anti-bending capability, high mechanical strength, and long service life.

Description

Flat cable

Technical field

The utility model relates to technical field of electric wires and cables, and more particularly, it relates to a kind of flat cable.

Background technology

Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.Cable can electric energy transmitting, signal and is realized electromagnetic conversion, transferring electric power as power cable, overhead wire etc., the more common flat cable of the kind of cable.But flat cable of the prior art exists, warping resistance ability is poor, the shortcoming of bad mechanical strength, and flat cable is through being usually used in frequent bending occasion, this just makes the life-span of flat cable low.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of flat cable, and this flat cable has advantages of that warping resistance ability is strong, mechanical strength is high, high life.

For achieving the above object, the utility model provides following technical scheme: a kind of flat cable, comprise cable inner core and be wrapped in the cable cover(ing) in cable inner core outside, described cable inner core comprises multiple sub-cable inner cores, the core of described sub-cable inner core is all in same level and be and be arranged side by side, between described cable cover(ing) and cable core, be provided with filler, in described filler, be embedded at least one and be the banded titanium alloy sheet arranging, on described titanium alloy sheet, be equipped with through hole, described through hole all arranges along cable inner core bearing of trend.

The utility model is further set to: described through hole is waist through hole.

The utility model is further set to: the quantity of described titanium alloy sheet is 2 and lays respectively at the both sides of the core place plane of cable inner core.

By adopting technique scheme, the titanium alloy sheet and the through hole that in filler, are embedded with through hole are along the setting of cable inner core bearing of trend, because titanium alloy itself has that mechanical strength is high, the advantage of good toughness and waist through hole is set therein can further improves titanium alloy sheet toughness and elasticity, and then improved warping resistance ability, the mechanical strength of this flat cable, improve the advantage of flat cable high life.

The utility model is further set to: the cross section of described sub-cable inner core is all regular hexagon setting.

The utility model is further set to: every described sub-cable inner core includes core conductor, is wrapped in the insulating barrier outside core conductor, and the cross section of described core conductor is all regular hexagon setting.

By adopting technique scheme, sub-cable inner core and core conductor are all arranged to regular hexagon, thereby such design can make to arrange the compacter mechanical strength that further improves flat cable and then the useful life of prolongation flat cable between each sub-cable inner core.

The utility model is further set to: described filler is refractory glass fiber.

The utility model is further set to: described insulating barrier is crosslinked polyetylene insulated layer.

By adopting technique scheme, the design of refractory glass fiber and crosslinked polyetylene insulated layer can improve the flame-resistant insulation of flat cable, can further improve its useful life.

The utility model is further set to: described cable cover(ing) comprises inner sheath and oversheath, and described inner sheath is worked out by steel wire.

By adopting technique scheme, the inner sheath that steel wire is worked out is wrapped in filler surface, the inner sheath being compiled into due to steel wire has advantages of that good toughness, elasticity are high, extend its useful life thereby such design just can further improve the toughness of flat cable.

Embodiment

Referring to figs. 1 through Fig. 2, the utility model flat cable embodiment is described further.

A kind of flat cable, comprise cable inner core 1 and be wrapped in the cable cover(ing) 2 in cable inner core 1 outside, described cable inner core 1 comprises multiple sub-cable inner cores 11, the core of described sub-cable inner core 11 is all in same level and be and be arranged side by side, between described cable cover(ing) 2 and cable core, be provided with filler, in described filler, be embedded at least one and be the banded titanium alloy sheet 3 arranging, on described titanium alloy sheet 3, be equipped with through hole, described through hole is all along the 1 bearing of trend setting of cable inner core.

Described through hole is waist through hole 31(and it should be noted that herein, and the shape of through hole can be also circular or square, considers toughness and elastic reaction that through hole plays, thus the present embodiment preferably through hole be waist through hole 31).

The quantity of described titanium alloy sheet 3 is 2 and lays respectively at the both sides of the core place plane of cable inner core 1.

By adopting technique scheme, the titanium alloy sheet 3 and the through hole that in filler, are embedded with through hole are along the 1 bearing of trend setting of cable inner core, because titanium alloy itself has that mechanical strength is high, the advantage of good toughness and waist through hole 31 is set therein can further improves titanium alloy sheet 3 toughness and elasticity, and then improved warping resistance ability, the mechanical strength of this flat cable, improve the advantage of flat cable high life.

The cross section of described sub-cable inner core 11 is all regular hexagon setting.

Every described sub-cable inner core 11 includes core conductor 111, is wrapped in the insulating barrier outside core conductor 111, and the cross section of described core conductor 111 is all regular hexagon setting.

By adopting technique scheme, sub-cable inner core 11 and core conductor 111 are all arranged to regular hexagon, thereby such design can make to arrange the compacter mechanical strength that further improves flat cable and then the useful life of prolongation flat cable between each sub-cable inner core 11.

Described filler is refractory glass fiber 4.

Described insulating barrier is crosslinked polyetylene insulated layer 112.

By adopting technique scheme, the design of refractory glass fiber 4 and crosslinked polyetylene insulated layer 112 can improve the flame-resistant insulation of flat cable, can further improve its useful life.

Described cable cover(ing) 2 comprises inner sheath 21 and oversheath 22, and described inner sheath 21 is worked out by steel wire.

By adopting technique scheme, the inner sheath 21 that steel wire is worked out is wrapped in filler surface, the inner sheath 21 being compiled into due to steel wire has advantages of that good toughness, elasticity are high, extend its useful life thereby such design just can further improve the toughness of flat cable.
