Abstract
The utility model is suitable for the cable field, and provides a cable liable to bend. The cable comprises insulation wires, an inner protection layer, a steel band armor layer, a reinforcement fiber layer, an outer protection layer and a flexible core wire. The flexible core wire is arranged at the center of the cable in the axial direction of the cable, spacing layers are extended in the radial direction of the cable, the spacing layers are provided with spacing grooves axially crossing through the cable, and the insulation wires are imbedded inside the spacing grooves. By arranging the flexible core wire at the internal center of the cable and with the spacing layers extended, mutual friction between insulation layers of the insulation core wire is prevented, the toughness and fatigue resistance of the cable are improved, the service lifetime of the cable is prolonged, and the safety performance of the cable is improved, furthermore, a motion range of the insulation wires can be limited by the spacing layers, and the cable can be prevented from shifting due to an bending angle being too large.
Description
Technical field
The utility model belongs to field of cables, relates in particular to a kind of cable that is easy to bending.
Background technology
Existing cable generally includes insulation core wire, sheath, steel-tape armouring layer, reinforcing fibre layer and outer jacket from inside to outside, the concrete certain resistance to tension of this cable, but lay knock off and installation process in more difficult while needing bending, and meeting phase mutual friction between the insulating barrier of adjacent insulation core wire, thereby can reduce toughness and the anti-fatigue performance of cable, in long-term use procedure, if bending cable repeatedly, easily make insulating barrier or other gelatinous layer of insulation core wire in cable be fractureed, occur the danger of electric leakage; In addition, existing cable is when bending, and the problem because being difficult to set back after bending displacement easily occurs the insulation core wire that distortion angle is large, and through the accumulation of many places bending, insulation core wire can occur not concordant problem at the radial section of cable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cable that is easy to bending, is intended to solve cable of the prior art and the line insulating layer of insulating core easily occurs or other gelatinous layer is fractureed and the problem because being difficult to set back after bending displacement easily occurs insulation core wire because of bending.
The utility model is to realize like this, a kind of cable that is easy to bending, comprise insulated conductor, sheath, steel-tape armouring layer, reinforcing fibre layer and outer jacket, it is characterized in that, described cable also comprises a flexible heart yearn, and described flexible heart yearn is arranged at the center of cable along the axial direction of described cable, and extends spacing layer along the radial direction of cable, described spacing layer is provided with the stopper slot that runs through cable axial direction, and described insulated conductor is embedded in described stopper slot.
Further, described insulated conductor is located in the stopper slot of described flexible heart yearn spaced reciprocally.
Further, described flexible heart yearn adopts nylon material manufacture to form.
The utility model compared with prior art, beneficial effect is: the utility model is provided with flexible heart yearn at the inside center place of cable, the extended spacing layer of flexible heart yearn can prevent phase mutual friction between the insulating barrier of insulation core wire, toughness and the anti-fatigue performance of cable have been improved, extend the useful life of cable, strengthened the security performance of cable, simultaneously, spacing layer can limit the scope of activities of insulated conductor, has prevented the problem that cable is subjected to displacement because bending angle is excessive.
Accompanying drawing explanation
Fig. 1 is a kind of stereochemical structure cross-sectional schematic that is easy to the cable of bending that the utility model embodiment provides.
Fig. 2 is the cross-sectional schematic of the cross section of cable shown in Fig. 1.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 2, for a kind of cable 100 that is easy to bending of the present utility model, comprise insulated conductor 1, sheath 2, steel-tape armouring layer 3, reinforcing fibre layer 4, outer jacket 5 and a flexible heart yearn 6, flexible heart yearn 6 is arranged at the center of cable 100 along the axial direction of cable 100, and extend spacing layer 61 along the radial direction of cable 100, spacing layer 61 is provided with the stopper slot (not shown) that runs through cable 100 axial directions, and insulated conductor 1 is embedded in stopper slot.
Particularly, above-mentioned insulated conductor 1 is located in the stopper slot of flexible heart yearn 6 spaced reciprocally, and flexible heart yearn 6 adopts nylon material manufacture to form.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
