Description
Technical Field
The utility model belongs to the field of household and office electric appliances, and particularly relates to a reinforced core combined insulated cable.
Background
The existing fixed wiring sheathed cable for household (namely the sheathed cable for home office power distribution) adopts a circular structure through pipe arrangement. Since the electric wire and cable are installed in a wall body or a floor, difficulties are caused in installation, maintenance and replacement of the electric wire and cable. When the existing fixed wiring sheath cable for home is used for burying a pipeline underground, a traction rope needs to be preset in the pipeline. Once the traction rope is broken, the installation is not possible, and the household electricity utilization is affected. The existing fixed wiring sheath cable for home is arranged in a pipeline to influence heat dissipation. Long term heat build-up will accelerate degradation of the insulation resulting in reduced cable life. The existing fixed wiring sheath cable for home is installed in a wall body or a floor. Once a cable is short-circuited or mechanically damaged, it is difficult to replace the cable by a convenient means. If the electric drill drills through the floor slab to cut off the cable in the neighbor decoration process, the pipeline and the cable are damaged due to fire disasters caused by overload or short circuit of the cable. In these cases it is difficult to remove the cable from the conduit and then re-route a new cable.
SUMMERY OF THE UTILITY MODEL
In view of the above, it is an object of the present invention to provide a core-stiffened, insulated electrical cable for overcoming the above problems or at least partially solving or alleviating the above problems.
The utility model provides a reinforced core combined insulated cable, which comprises:
the insulation support frame is axially arranged in the insulation tube, the cross section of the insulation support frame divides the cross section of the insulation tube into a plurality of fan-shaped areas, a through hole is formed in the center of the insulation support frame, and a metal reinforcing core is arranged in the through hole;
the metal conductor is arranged in a sector area divided by the insulation support frame in the insulation tube;
the protective sleeve is directly or indirectly sleeved on the outer side of the insulating pipe.
The utility model also has the following optional features.
Optionally, a gap between the metal conductor and the insulation support frame and the insulation tube thereof is filled with insulation paste or insulation powder.
Optionally, the metal conductor is wound with a high temperature resistant tape on the surface.
Optionally, the cross section of the insulating support frame is in a cross shape.
Optionally, the cross section of the insulating support frame is in a shape like a Chinese character 'ya', a Chinese character 'fire', a Chinese character 'mu' or a Chinese character 'mi'.
The utility model has the beneficial effects that:
the reinforced core combined insulated cable meets the reasonable requirements of modern home and office buildings on beautiful decoration, simple and convenient installation and convenient use, and solves the problem of high cost caused by extruding (filling) the insulating layers outside the conductors of the existing electric wires and cables. Meanwhile, because a plurality of conductors are distributed in a loose space, the friction resistance of the leading-out conductors is relatively small, the damaged conductor wire cores can be replaced more conveniently, and a soft copper conductor arranged in the center of the support frame can not only play a role in enhancing the strength of the support frame, but also be used as a conductive wire core during the production of the support frame.

Detailed Description
Referring to fig. 1, an embodiment of the present invention proposes a reinforced core combined insulated cable including: an insulating tube 5, a metal conductor 1 and a sheath tube 6; an insulating support frame 4 is axially arranged in the insulating tube 5, the cross section of the insulating support frame 4 divides the cross section of the insulating tube 5 into a plurality of sector areas, a through hole is formed in the center of the insulating support frame 4, and a metal reinforcing core 7 is arranged in the through hole; the metal conductor 1 is arranged in a sector area divided by the insulation support frame 4 in the insulation tube 5; the protective sleeve 6 is directly or indirectly sleeved on the outer side of the insulating tube 5.
After the metal conductors 1 are prepared, the metal conductors 1 are respectively fixed in the insulation gaps of the insulation support frame 4 by adopting a cabling process. And completing the insulation production of a plurality of metal conductors 1 by cabling at one time. Because insulating support frame 4 has good insulating properties, just need not respectively extrude the insulating layer on each metallic conductor 1 surface, the cable self does not prolong when burning, can not produce toxic gas, and protective sleeve 6 can adopt the extrusion of thermoplastic sheath materials such as polyolefin, rubber, and the extrusion mode can be crowded tubular also can be the extrusion of extrusion formula, provides necessary protection for this product.
Referring to fig. 1, according to an embodiment of the present invention, a gap between the metal conductor 1 and the insulation support frame 4 and the insulation tube 5 thereof is filled with an insulation paste or an insulation powder 3.
When the possibility of water and oil entering into the electric wire and cable is considered, the insulating paste or the insulating powder 3 can be filled between the insulating support frame 4 and the metal conductor 1, so that the insulating property and the water resistance of the electric wire and cable can be improved, and the insulating paste or the insulating powder 3 is cable paste or mineral insulating powder and the like.
Referring to fig. 1, according to an embodiment of the present invention, a metal conductor 1 is surface-wound with a high temperature resistant tape 2.
In order to identify different wire cores conveniently, the surface of the metal conductor 1 is wound with the high-temperature resistant belts 2 made of fluoroplastics with different colors, and the high-temperature resistant belts 2 made of fluoroplastics with different colors can also be simultaneously twisted in the twisting process of the metal conductor 1. When the actual working temperature of the cable is not higher than 70 ℃, materials such as polyvinyl chloride insulating tapes, polyolefin insulating tapes or rubber insulating tapes with different colors can be adopted to identify different wire cores.
Referring to fig. 1, the cross-section of the insulating support 4 is cross-shaped according to an embodiment of the present invention.
The cross section of the insulating support frame 4 adopts a cross-shaped structure, so that four fan-shaped spaces can be formed between the insulating support frame 4 and the protective sleeve 6, and four metal conductors 1 can be accommodated.
