Description

Reinforced heating wire

Technical field

The utility model relates to a kind of electric wire, belongs to technical field of electric wires and cables.

Background technology

Electric wire refers to the material for electric power, communication and associated transport purposes.Electric wire and cable does not have strict boundary.Conventionally core number is few, product diameter product little, simple in structure is called electric wire, not insulation be called bare wire, other be called cable.Electric wire is comprised of one or a few soft wire, and outer bread is with light and soft sheath.Along with the raising day by day of living standard, people have proposed higher performance requirement to the electric wire of electric equipment, require tensile strength high, and resistance to bending performance is good, durable in use.

At present, part adopts copper rod is drawn into after the copper wire of certain wire diameter as the wire of power line and electric heating wire, in outer cladding, processes as insulating polymeric materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC).Although this wire also can meet the instructions for use in certain limit, in use procedure very easily due to mechanical damage or overheatedly cause that any place damages, and causes whole electric equipment to use.

Chinese patent 200920263845.4 discloses a kind of LED flexible neon, comprise heart yearn, be coated on heart yearn outside crust, be arranged on LED bulb in heart yearn and through the copper twisted wire in heart yearn, the lamp base of described LED bulb is electrically connected to copper twisted wire, in described copper twisted wire, be provided with a carbon fiber wire, described carbon fiber wire and described copper twisted wire are isometric.Though this stranded wire strength strengthens to some extent, reliability fail safe is still not good, cannot use as electric heating wire.

Utility model content

The technical problems to be solved in the utility model is, provides a kind of resistance to bending performance good, still can normally use safe and reliable reinforced heating wire after slightly losing.

The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of reinforced heating wire, comprises and lead core, conductor bar, wire, fiber braiding layer and external insulation layer; Described conductor bar has 2 to 5, described in described each conductor bar is spirally wound on side by side, leads on core; Described wire has 5 to 30, described in described each wire is spirally wound on side by side, leads on core and between adjacent conductor bar; Described fiber braiding layer is coated on outside described conductor bar and wire, and described external insulation layer is coated on outside described fiber braiding layer.

Technique scheme preferably a kind of: the above-mentioned core of leading is solid conductor, described in lead core wire diameter be 0.3mm to 5mm.

Technique scheme preferably a kind of: the above-mentioned core of leading is twisted wire, one metal wire is stranded forms by 7 to 60, and described wire diameter wiry is 0.03mm to 0.2mm, and described wire is enamelled wire.

Technique scheme preferably a kind of: the above-mentioned core of leading is twisted wire, by 30 to 120 one metal wires be twisted into 2 to 20 strands again twice stranding form, described wire diameter wiry is 0.03mm to 0.2mm, described wire is enamelled wire.

Technique scheme preferably a kind of: above-mentioned reinforced heating wire also comprises inner insulating layer, leads outside core described in described inner insulating layer is coated on.

Technique scheme preferably a kind of: above-mentioned conductor bar is that width is 1mm to 4mm, and thickness is 0.08mm to 0.15mm metal tape.

Technique scheme preferably a kind of: the wire diameter of above-mentioned wire is 0.05mm to 0.5mm.

The utlity model has positive effect: reinforced heating wire of the present utility model adopts conductor bar and wire together to reel side by side conductor as inner core, can be so that the resistance to bending performance of reinforced heating wire promote greatly, fatigue resistance increases than the reinforced heating wire of common electric equipment.Lead core, conductor bar and the wire of this heater wire are all conductors, even if there is during use part to lose also, can not form and open circuit, and can normally use.This reinforced heating wire outer wrapping fiber braid and insulating barrier, have good electrical insulation capability, and higher serviceability temperature and good bending resistance folding endurance are safe and reliable during use.
