Abstract
A metal shielded aluminum alloy power cable mainly solves the problem that a conventional metal shielded cable is low in tensile strength, and may distorted and broken when subjected to outer force. The metal shielded aluminum alloy power cable is characterized in that a positioning rib is arranged between adjacent wire core wrapping bands, the surface of the positioning rib contacts the outer surface of the wire core wrapping bands, fixed filling material is arranged in the center of an insulating layer, the surface of the fixed filling material contacts the outer surface of the wire core wrapping bands, and an armored layer formed by tensile aluminum alloy wound on the outer surface of the insulating layer is arranged outside the insulating layer. The metal shielded aluminum alloy power cable changes the structure of a tensile aluminum alloy band, may not be loosen when subjected to great pulling force, and substantially increases the tensile strength and the application scope of a mechanism. Since a positioning rib and solid filling material are employed, the wire core wrapping bands outside a conductive core may not extrude and rub with each other, and the strength and safety coefficient of the product are improved.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of metal shielding type aluminium alloy power cable.
Background technology
China " 12 " planning highlights energy-conservation, sustainable development, and " with aluminium for copper " has become the inexorable trend of cable industry Transformation Development, and aluminium alloy cable, as novel energy-saving material, meets the new approaches of low-carbon environment-friendly.Along with the development of electronic product is universal, aluminium alloy cable is widely used in the electric connection of each class of electronic devices such as household electrical appliance, instrument and meter, electric tool and automation equipment as the delivery means of a kind of transferring electric power signal or data-signal simultaneously.
Existing metal sheathed cable generally all is provided with one deck armouring screen, prevents electromagnetic interference.The compression strength of this layer of cable is higher, but this armour tensile strength is lower.Large at some erecting cable degree of speeding, the occasion that the span spacing is large, especially cross river, the occasion in sea excessively, and the armoured cable of this structure just is difficult to set up.There is the gap of activity relatively simultaneously in the cable of this structure between conductor wire core, can cause the mutual distortion between each conductor wire core under the effect of external force, cause even sheath fracture of conductor wire core, to personal safety, cause hidden trouble.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of metal shielding type aluminium alloy power cable, has mainly solved existing metal sheathed cable tensile strength low, and conductor wire core is the problem of twisting and breaking under external force easily.
The technical scheme that the utility model adopts is: a kind of metal shielding type aluminium alloy power cable, comprise insulating barrier, be provided with some groups of conductor wire cores in described insulating barrier, described conductor wire core is wrapped with the core band, be provided with positioning bar between adjacent described core band, described positioning bar surface fits with core band outer surface, described insulating barrier center is provided with fixedly filler, described fixedly filling surface and core band outer surface fit, described insulating barrier is provided with armour outward, described armour consists of the tension aluminum alloy strip that is wound in the insulating barrier outer surface, the interconnective curved surface in Wei Liangge edge, cross section of described tension aluminum alloy strip.
Described armour is provided with sheath outward, described sheath and armour interference fit.
Be provided with four groups of conductor wire cores in described insulating barrier.
Described positioning bar and insulating barrier adopt integral structure.
Described fixedly filler consists of synthetic rubber.
Described conductor wire core is made by aluminium alloy.
Be provided with metal screen layer between described insulating barrier and armour.
The beneficial effects of the utility model are: the structure that has changed the tension aluminum alloy strip, can bear extraneous pullling and do not get loose energetically, tensile strength and the scope of application of mechanism have greatly been improved, positioning bar and solid packing have been increased simultaneously, the outer core band of conductor wire core is extrusion friction mutually not, has improved intensity and the coefficient of safety of product.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is tension aluminum alloy strip 61.
1-insulating barrier in figure, the 2-conductor wire core, 3-core band, the 4-positioning bar, 5-is filler fixedly, 6-armour, 61-tension aluminum alloy strip, 7-sheath, 8-metal screen layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 with Figure 2, a kind of metal shielding type aluminium alloy power cable, comprise insulating barrier 1, be provided with some groups of conductor wire cores 2 in described insulating barrier 1, described conductor wire core 2 is wrapped with core band 3, be provided with positioning bar 4 between adjacent described core band 3, described positioning bar 4 surfaces fit with core band 3 outer surfaces, described insulating barrier 1 center is provided with fixedly filler 5, described fixedly filler 5 surfaces fit with core band 3 outer surfaces, the outer armour 6 that is provided with of described insulating barrier 1, described armour 6 consists of the tension aluminum alloy strip 61 that is wound in insulating barrier 1 outer surface, the interconnective curved surface in Wei Liangge edge, cross section of described tension aluminum alloy strip 61.Adopt the aluminum alloy strip lock armo, its linkage structure between layers, improved tensile strength and the scope of application of mechanism greatly.
The outer sheath 7 that is provided with of described armour 6, described sheath 7 and armour 6 interference fit.Compressing armour 6 prevents from becoming flexible.
Be provided with four groups of conductor wire cores 2 in described insulating barrier 1.
Described positioning bar 4 adopts integral structure with insulating barrier 1.Intensity and the toughness of insulating barrier 1 have further been improved.
Described fixedly filler 5 consists of synthetic rubber.Can absorb external force and prevent that conductor wire core from moving or distortion by distortion.
Described conductor wire core 2 is made by aluminium alloy.
Be provided with metal screen layer 8 between described insulating barrier 1 and armour 6.In transmission current, signal, metal screen layer forms an electromagnetic circuit, can stop the external electromagnetic ripple to electronic equipment, and the interference of industrial equipment, improve its serviceability.
The utility model is concrete use as follows: during coiling tension aluminum alloy strip 61, the cooperation that mutually superposes of the front and back curved surface on tension aluminum alloy strip 61, and by sheath 7 compressions.When pulling force acts on cable, because curved surface is withheld together mutually, can be out of shape in right amount the absorption pulling force, greatly improved the tensile strength of mechanism.When the external impacts cable, positioning bar 4, fixing filler 5 distortion impact-absorbing power, protection core band 3, prevent that core band 3 from being destroyed by friction.And due to positioning bar 4, fixedly filler 5 is fitted in core band 3 outer surfaces, has not only kept apart conductor wire core 2, and conductor wire core 2 is not easy the mobile friction that produces.
The beneficial effect of utility model is: the structure that has changed the tension aluminum alloy strip, can bear extraneous pullling and do not get loose energetically, tensile strength and the scope of application of mechanism have greatly been improved, positioning bar and solid packing have been increased simultaneously, the outer core band of conductor wire core is extrusion friction mutually not, has improved intensity and the coefficient of safety of product.
