Abstract
An insulating wirewound moulded fusing resistor is characterized in that: a resistance wire is wound round an inner core, both ends of the inner core are provided with a lead which is connected with the resistance wire, the inner core and the resistance wire thereon are enveloped with an insulation crust, the lead connected with the resistance wire penetrates through the insulation crust, an antiflaming layer is filled between the insulation crust and the inner core, and the inner core and the resistance wire are covered with the antiflaming layer. The invention has the advantages of reasonable structure, high reliability, and good corrosion resistance, insulativity and security, and can be used under harsh conditions.
Description
Technical field
The present invention relates to a kind of Fuse Type resistor.
Background technology
The structure of existing a kind of Fuse Type resistor is: be wound with resistance wire on the inner core, the two ends of inner core are respectively equipped with the lead that joins with resistance wire, at the flame retardant paint that is externally coated with of inner core and resistance wire.The main deficiency that the resistor of this structure exists is: corrosion resistance and insulating properties are not high, are not suitable for working under rugged environment; Resistor when occurring exceeding the situation of its nominal working conditions or instantaneous pressure, because of the fusing of resistance wire, might cause to burst or phenomenon that naked light occurs at work, and this phenomenon then causes the generation of second accident easily.
Summary of the invention
The object of the present invention is to provide a kind of Fuse Type resistor, its corrosion resistance and good insulating, and when resistance wire fuses do not have and burst or the generation of naked light phenomenon.
For achieving the above object, the present invention adopts following scheme: insulating wirewound moulded fusing resistor, be wound with resistance wire on the inner core, the two ends of inner core are provided with the lead that joins with resistance wire, the outer envelope of inner core and last resistance wire thereof has insulation crust, lead pass-out insulation crust with resistance wire joins is filled with flame-retardant layer between insulation crust and inner core, flame-retardant layer is with inner core and resistance wire parcel.
By such scheme as seen, in the Fuse Type resistor provided by the invention, because the outer envelope of inner core and resistance wire has insulation crust, its corrosion resistance and insulating properties are greatly improved; Be filled with flame-retardant layer between insulation crust and inner core, when resistance wire fused, flame-retardant layer can be avoided insulation crust to burst, reach the naked light phenomenon, prevents the generation of second accident.
The present invention is rational in infrastructure, reliability is high, and its corrosion resistance, insulating properties and fail safe are good, can work than under the harsh conditions.
Description of drawings
The structural representation of Fig. 1 one embodiment of the invention.
Embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
Be wound with resistance wire 3 on the inner core 4 of Fuse Type resistor provided by the invention, the two ends of inner core 4 are respectively equipped with the lead 6 that joins with resistance wire 3, the outer envelope of inner core 4 and last resistance wire 3 thereof has insulation crust 1, the lead 6 that joins with resistance wire 3 stretches out in insulation crust 1, be filled with flame-retardant layer 2 between insulation crust 1 and inner core 4, flame-retardant layer 2 is with inner core 4 and resistance wire 3 parcels.
By accompanying drawing as seen, in the present embodiment, lead 6 with the connected mode of resistance wire 3 is: be with cap 5 at the two ends of inner core 4, resistance wire 3 joins with cap 5, and an end and the cap 5 of lead 6 join.In addition, for guaranteeing the reliability of this Fuse Type resistor, flame-retardant layer 2 wraps up cap 5 and lead 6 with the position that cap 5 joins.The material of flame-retardant layer 2 is the mineral-type fire retardant, as magnesium hydroxide.The material of insulation crust 1 is a phenolaldehyde moulding compound, the position parcel that flame-retardant layer 2 joins inner core 4, resistance wire 3, cap 5 and lead 6 and cap 5 in the mode that applies, and insulation crust 1 adopts the mode of mold pressing that flame-retardant layer 2 is sealed.
Claims (2)
1, insulating wirewound moulded fusing resistor, be wound with resistance wire on the inner core, the two ends of inner core are provided with the lead that joins with resistance wire, it is characterized in that: the outer envelope of inner core and last resistance wire thereof has insulation crust, the lead pass-out insulation crust that joins with resistance wire, be filled with flame-retardant layer between insulation crust and inner core, flame-retardant layer is with inner core and resistance wire parcel.
2, insulating wirewound moulded fusing resistor according to claim 1 is characterized in that: the two ends at inner core are with cap, and resistance wire and cap join, and an end and the cap of lead join, the position parcel that flame-retardant layer joins cap and lead and cap.
