Abstract
The utility model discloses a flexible cable of special control of thin wall type fan motor, including a plurality of eradications along heart yearn, cladding in insulating heart yearn around the covering, have the heat -resisting fire -retardant insulating polyvinyl chloride restrictive coating of irradiation of exempting from around the outer cladding of covering, insulating heart yearn constitute by conductor and the insulating layer of cladding on the conductor, insulating layer thickness attenuate 13, the utility model provides a though flexible cable of special control of thin wall type fan motor has reduced the quantity of insulating layer material in a large number, the insulating properties under its high temperature does not show declines that lands, still satisfies the basic demand to the cable nature that insulates under high temperature environment of fan motor.
Description
Technical field
The utility model relates to data cable, is specifically related to the special control flexible cable of a kind of thin wall type blower motor.
Background technology
The blower fan of the equipment such as central air-conditioning, workshop ventilation, HVAC uses for a long time in high temperature environments, under the cable of its blower motor is also in hot environment certainly.The sheath material of current blower motor cable is made up of polyvinyl chloride usually, it belongs to the not high material of heatproof, can the high temperature of resistance to 105 DEG C, when cable is in operation the too high or load height of electric current, be easy to require that producing colloidal sol ftractures and burn because temperature resistant grade does not reach, the a large amount of toxic smog of easy generation, to the environment of surrounding, brings certain potential safety hazard to production and life.
Applicant replaces traditional pvc sheath layer by adopting heat-resisting irradiation fire retardant insulating pvc sheath layer of exempting from, not only environmental protection flame retardant, also reach the job requirement of Long-Time Service under 125 DEG C of hot environments, improve the security performance under blower motor hot environment.But owing to requiring higher to the insulating properties under cable core hot environment, usually adopt thicker insulating barrier to ensure the insulating properties of cable.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of thin wall type blower motor special control flexible cable, and this cable not only has high pliability and oil resistant, fire-retardant, high and low temperature resistance, and drastically reduce the area the consumption of insulating layer material.
In order to realize above-mentioned object, the utility model provides following technical scheme:
Thin wall type blower motor of the present utility model special control flexible cable includes some insulation core wires, is coated on the lapping layer of described insulation core wire, described lapping layer is coated with heat-resistingly exempts from irradiation fire retardant insulating pvc sheath layer, described insulation core wire is made up of conductor and the insulating barrier be coated on conductor, described thickness of insulating layer thinning 1/3.
Wherein, heat-resisting utility model patent (the application number: 201310682066.9) one is heat-resisting exempts from irradiation PVC fire retardant insulating automotive line material and preparation method thereof of exempting from irradiation fire retardant insulating polyvinyl chloride and applying for see Wuhan Yong Xin plastic material Co., Ltd of the material of restrictive coating, be and wherein said heat-resistingly exempt from irradiation PVC fire retardant insulating automotive line material, its technical scheme is:
One is heat-resisting exempts from irradiation PVC fire retardant insulating automotive line material, is prepared from by the raw material of following percentage by weight:
Polyvinyl chloride: 45 ~ 57%
Stabilizer: 4.2 ~ 6.7%
Plasticizer: 21 ~ 22.8%
Filler: 14 ~ 19.5%
Fire retardant: 0.7 ~ 1.2%
Lubricant: 0.7 ~ 0.8%
Processing aid: 0.45 ~ 1.6%
By skin couplant: 1.4 ~ 3.1%
Described by skin couplant by calcium oxide, lipophile activating agent and surfactant according to 3: 1: 2.5 weight form.
Preferably, the special control flexible cable of described thin wall type blower motor includes at least three insulation core wires;
Further, the special control flexible cable of described thin wall type blower motor includes four insulation core wires.
Preferably, described insulation core wire is combined by stranded mode.
Wherein, described conductor is selected from copper, tin-coated copper, nickel-clad copper, silver-plated copper, aluminium etc.; Described insulating barrier is selected from polypropylene (PP), polyvinyl chloride (SR-PVC), polyethylene (PE), polyfluorinated ethylene (FEP), Meltability polytetrafluorethyletubular (PFA), ethylene-tetrafluoroethylene copolymer (ETFE), chlorotrifluoroethylene (ECTFE), polyvinylidene fluoride (PVDF) etc.; Described lapping layer is selected from banded paper tape, mica tape, alkali-free glass fibre band, nonwoven fabrics, plastic tape, wire cotton yarn or silk etc.
Although the special control flexible cable of the thin wall type blower motor that the utility model provides substantially reduce the number the consumption of insulating layer material, but the insulation property under its high temperature do not decline significantly, still meet blower motor in high temperature environments to the basic demand of Cable insulation.
