Abstract

The utility model discloses a novel durable coal cutter metal shielding rubber sleeve flexible cable. The cable is composed of three power wire cores, one ground wire core and one control wire core. The power wire cores and the control wire core are arranged in a square shape whose center is provided with one ground wire core. Each power wire core is composed of, from inside to outside in turn, a power wire core conductor, a power wire core insulating layer and a metal fiber weaving shielding layer. The control wire core is internally provided with three control wire core conductors which are arranged in an equilateral triangle. Each control wire core conductor is externally wrapped with a control wire core insulating layer. The three control wire core conductors are externally provided with a control wire core wrapping layer. The outmost layer of the cable is wrapped with an external sheath. The novel durable coal cutter metal shielding rubber sleeve flexible cable is the metal shielding rubber sleeve flexible cable which is high in flexibility (mobility), great in bending resistance, excellent in wear resistance and high in impact resistance and anti-extruding performance for a coal cutter.

Description

A kind of novel durable coal mining machine flexible cable with metallic shielding rubber sleeve

Technical field

The utility model belongs to field of cables, relates in particular to a kind of novel durable coal mining machine flexible cable with metallic shielding rubber sleeve.

Background technology

At present, coal-winning machine all adopts line diameter to be less than the fine copper wire of 0.51mm with metal-shielded rubber-sheathed flexible cable, conductor outermost layer direction of lay is left-hand, the adjacent layer opposite direction, the stranded surperficial pitch ditch of conductor is obvious, affects insulating exruded effect, cable fiber woven material and oversheath tensile strength are low, cable is low useful life, generally, in 3 months, can not meet consumers' demand.

The utility model content

The purpose of this utility model, for a kind of novel durable coal mining machine flexible cable with metallic shielding rubber sleeve is provided, has solved above-mentioned mentioned problem.

The utility model is achieved in the following ways: comprise the power core, ground wire core conductor and control core, described cable is by three power cores, a ground wire core conductor and a control core form, the power core is square arrangement with the control core, there is a ground wire core conductor centre, described power core is from inside to outside successively by the power line core conductor, power line core insulation layer, the metallic fiber woven shield forms, described control line core inner has three control line core conductors that are triangular arranged, control line core insulation layer is all wrapped up in every control line core conductor outside, there is the core of control coating layer three control line core conductor outsides, the outermost layer of cable is coated with oversheath.

Described power line core conductor and control line core conductor are by zinc-plated soft copper conductor stranded forming in the same way, and the outermost layer direction of lay is left-hand, and line diameter is less than 0.3mm.

Described metallic fiber woven shield adopts the band covering to add tinned wird and dacron thread.

Described oversheath adopts haloflex.

The beneficial effects of the utility model are: in tinned conductor, line diameter is less than 0.3mm, adopt stranded in the same way, the outermost layer direction of lay is left-hand, the stranded surface of conductor is without the pitch ditch of multiple strand, insulating exruded effective, conductor structure is more soft, and bending property is better, is that a kind of flexibility (mobility) is high, bending resistance is good, resistance to wear is good, impact resistance and the strong coal-winning machine metal-shielded rubber-sheathed flexible cable of anti-extrusion performance.

The accompanying drawing explanation

Fig. 1 is cross section structure schematic diagram of the present utility model.

In figure, 1, the power core; 2, power line core conductor; 3, power line core insulation layer; 4, metallic fiber screen; 5, ground wire core conductor; 6, control core; 7, control line core conductor; 8, control line core insulation layer; 9, control the core coating layer; 10, oversheath.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described, as shown in Figure 1: a kind of novel durable coal mining machine flexible cable with metallic shielding rubber sleeve, comprise three power cores (1), a ground wire core conductor (5) and a control core (6), three power cores (1) and a control core (6) are square arrangement, at power core (1) and in the middle of controlling core (6), a ground wire core conductor (5) are arranged.

Wherein, a power line core conductor (2) is arranged is that the outermost layer direction of lay is left-hand by zinc-plated soft copper conductor stranded forming in the same way in power core (1) inside, the stranded surface of conductor is without the pitch ditch of multiple strand, insulating exruded effective, conductor structure is more soft, and line diameter is less than 0.3mm.The outside power line core insulation layer (3) that coats of power line core conductor (2), the fibrage shielded layer of most external coated metal (4).

Control core (6) inside three control line core conductors (7) that are triangular arranged are arranged, the conductor material adopted and molding mode are identical with power core (1), control core (6) outside for every and all wrap up control line core insulation layer (8), control core (6) most external and be wrapped with control core coating layer (9).

The outermost layer of cable is coated with oversheath (10).
