Description
Technical field
The utility model is related to resistive technologies field, more particularly to a kind of explosion-proof flame-retardant resistance.
Background technology
Resistance is as one of electronic component, in circuit using the electric current, electricity widely, being mainly used in adjustment circuit
Pressure.Resistance can be generated heat in use, when the electric current flowed through is larger, and resistance can be caused to send substantial amounts of heat and occur quick-fried
Split, so as to damage circuit board.In order to prevent this from occurring, in the market occurs in that Anti-explosion resistor, such as Patent No.：
Plain conductor is provided with CN200820116166.X utility model patent document, entitled Anti-explosion resistor, the Anti-explosion resistor, when
When load current exceedes critical value, plain conductor fusing.So as to play explosion-proof effect.However, in resistance manufacturing process, surface
Will have coating, when larger current by when, wire does not fuse, and produces larger heat, and resistive surface temperature is higher,
Coating burning is may result in, so as to damage circuit board.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art there is provided a kind of explosion-proof flame-retardant resistance, and the resistance is not
Can occur spontaneous combustion, use safety.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：
A kind of explosion-proof flame-retardant resistance, including：Insulating bar；The two ends of insulating bar are connected to metal cap, the end of metal cap
Face is respectively connected with conductor, and the side of insulating bar is wound with metal wire, and the two ends of metal wire are connected with two metal caps respectively, insulation
Rod, metal wire and metal cap constitute resistance base body, and the surface of the resistance base body is covered with talcum resin bed；The talcum tree
The surface of lipid layer scribbles anti-flaming dope layer.
Further, the metal wire is PTC alloy wires.
Preferably, it is arranged with heat-shrinkable T bush outside resistance base body.
Further, insulating bar is ceramic rod.
Further, anti-flaming dope layer is silicone resin layer.
The beneficial effects of the utility model are：The utility model is by internally setting anti-flaming dope layer, so as to prevent electricity
Spontaneous combustion is hindered, had not only played explosion-proof but also can play fire-retardant effect.
Brief description of the drawings

Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment：Referring to Fig. 1, a kind of explosion-proof flame-retardant resistance, including：Insulating bar 1；The two ends of insulating bar 1 are connected to
Metal cap 2, the end face of metal cap 2 is respectively connected with conductor 3, and the side of insulating bar 1 is wound with metal wire 4, the two ends point of metal wire 4
It is not connected with two metal caps 2, insulating bar 1, metal wire 4 and metal cap 2 constitute resistance base body, the surface of the resistance base body
Covered with talcum resin bed 5；The surface of the talcum resin bed 5 scribbles anti-flaming dope layer 6.Metal cap 2 typically uses chapeau de fer.
Metal wire 4 in the technical program in use, when running into larger current, then can fuse, and prevent explosion；Its
It is secondary, because its surface scribbles anti-flaming dope, therefore its spontaneous combustion can be prevented.To reach explosion-proof effect, insulating bar 1 first applies talcum tree
Lipid layer 5 is coated on after internal layer, then is applied flame retardant coating 6 and be coated on outer layer.For convenience of identification resistance, applied on 6 surface of anti-flaming dope layer
There are some colour codings 7.
In the present embodiment, the metal wire 4 is PTC alloy wires.The resistance of PTC alloy wires is when temperature is higher, and resistance is got over
Greatly；Prevent to produce high current, protection circuit in circuit.
Preferably, heat-shrinkable T bush (being not drawn into figure) is arranged with outside resistance base body.Set heat-shrinkable T bush can be to inside
Resistance base body is protected.
Further, insulating bar 1 is ceramic rod.Ceramic rod has preferable insulating properties.
Further, anti-flaming dope layer 6 is silicone resin layer.Silicone resin has splendid heat resistance and weatherability, and has concurrently
Excellent electrical insulating property, hydrophobicity and anti-flammability.
It the above is only the preferred embodiment of the application, equivalent technical solutions on this basis still fall within application protection model
Enclose.
