Description
Technical Field
The utility model belongs to the field of household and office electric appliances, and particularly relates to a combined insulated cable.
Background
The existing electric power distribution for home office uses a sheathed cable with a circular structure and is arranged by a through pipe, and the installation, maintenance and replacement of the electric wires and cables are difficult because the electric wires and cables are installed in a wall body or a floor. When the pipeline is buried, a hauling 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. And the cable is difficult to dispel the heat in the pipeline, and long-term heat accumulation will accelerate insulating ageing thus lead to the cable life-span to reduce. 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.

Referring to fig. 1, an embodiment of the present invention provides a composite insulated cable including: an insulating tube 5 and a metal conductor 1; an insulating support frame 4 is axially arranged in the insulating tube 5, and the cross section of the insulating support frame 4 divides the cross section of the insulating tube 5 into a plurality of sector areas; the cross section of the insulating support frame 4 is of a structure in the shape of a Chinese character 'yi' or 'ya' or 'cross'; the metal conductor 1 is arranged in a sector area divided by the insulation support frame 4 in the insulation tube 5.
The insulating tube 5 can be extruded by thermoplastic insulating materials such as polyolefin, the extrusion mode can be a tube extrusion mode or an extrusion mode, the insulating tube 5 provides an insulating layer with a stable structure for a product, the stress of the metal conductor 1 is prevented from leaving a preset position, and meanwhile, the direct corrosion of corrosive substances to the metal conductor 1 is also prevented. The insulating support frame 4 is produced by adopting an extrusion type extruder, an extrusion type die with special size and structure is designed according to requirements, and the insulating support frame 4 is preferably produced by adopting high-density polyolefin but not limited by adopting other materials. The metal conductor 1 adopts a copper stranded conductor for electrician meeting the IEC60228 conductor of insulated cable standard, namely a high-purity soft copper wire special for the electrical industry, so that the product has good conductive capability and electromagnetic signal transmission performance, good conductive performance and tensile strength, is suitable for being installed by users in a small space, has good flexibility and can prolong the service life of the product.
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 the insulating support frame 4 has good insulating property, an insulating layer does not need to be extruded on the surface of each metal conductor 1, the cable does not delay combustion during combustion, and toxic gas is not generated. When the cross section of the insulating support frame 4 adopts a straight-line structure, two fan-shaped spaces can be formed between the insulating support frame 4 and the protective sleeve 5, and then the two metal conductors 1 can be accommodated; when the cross section of the insulating support frame 4 adopts a Y-shaped structure, three fan-shaped spaces can be formed between the insulating support frame 4 and the protective sleeve 5, and then three metal conductors 1 can be accommodated; when the cross section of the insulating support frame 4 adopts a cross-shaped structure, four fan-shaped spaces can be formed between the insulating support frame 4 and the protective sleeve 5, and four metal conductors 1 can be accommodated.
