Abstract
The utility model relates to a quick fusing resistor keeps warm, including plug, cap, lead wire, alloy silk, at the both ends of plug two caps of mirror symmetry spiral -lock, a lead wire is respectively connected to two caps, winding alloy silk on the plug, and the both ends of alloy silk are connected with two caps respectively, a coaxial suit insulation cover outside plug and cap, the both ends of insulation cover are passed through the insulating cement and are sealed. This resistance adopts the insulation cover to substitute the flame retardant paint, has solved the flame retardant paint heat dissipation, is unfavorable for the problem of alloy silk fusing, and the insulation cover has guaranteed that the temperature of alloy silk does not run off, compares the flame retardant paint, and the alloy silk is disconnected soon, in time the protection circuit.
Description
Technical field
This utility model belongs to resistance field, is related to fusing resistor, especially a kind of insulation quick fuse resistor.
Background technology
The structure of existing winding-type fuse-resistor is：The two ends of plug are cased with cap, and B alloy wire is wound with plug,
The two ends of B alloy wire are connected with two blocks respectively, are externally coated with flame retardant paint in plug, cap and B alloy wire.When by resistance
The current anomaly of device, and current value exceed its rated current it is larger when, B alloy wire heating make resistor temperature be quickly raised to close
Spun gold melting temperature, produced fusing before resistor surface carries out abundant heat exchange with its surrounding, played protection electricity
The purpose on road.
Flame retardant paint is a kind of heat radiating type coating, carries out heat exchange with its surrounding, can not only make resistor temperature fast
Speed is increased to the melting temperature of B alloy wire and produces fusing, and easily causes the temperature liter of resistor surface and its surrounding
Height, causes to burn out the phenomenon of other devices.
Utility model content
The purpose of this utility model be overcome the deficiencies in the prior art in place of, there is provided a kind of insulation quick fuse resistance
Device, it is ensured that B alloy wire accurate and effective can fuse.
This utility model solves the technical scheme that adopted of technical problem：
A kind of insulation quick fuse resistor, including plug, cap, lead, B alloy wire, in the two ends specular of plug
Two cap of spiral-lock, two caps respectively connect a lead, and B alloy wire is wound on plug, and the two ends of B alloy wire are connected with two caps respectively
Connect, in plug and cap one muff of outer coaxial package, the two ends of muff are sealed by insulating cement.
And, described muff is ceramic jacket.
And, described insulating cement is glass cement.
Advantage of the present utility model and good effect are：
1st, this resistance substitutes flame retardant paint using muff, solves flame retardant paint radiating, is unfavorable for the problem of B alloy wire fusing,
Muff ensure that the temperature of B alloy wire is not lost in, and compare flame retardant paint, and B alloy wire is disconnected soon, timely protection circuit.
2nd, this resistor structure is reasonable in design, it is easy to mechanization production, can greatly improve production efficiency.
3rd, this resistor is mainly used in the main circuit of the electrical equipment such as various chargers, instrument, has electric fuse and resistance
Dual property.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are simply retouched
The property stated, be not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of insulation quick fuse resistor, including plug 3, cap 4, lead 6, B alloy wire 2, in the two ends mirror image of plug
Symmetrical two cap of spiral-lock, each one lead of connection of two caps wind B alloy wire on plug, the two ends of B alloy wire respectively with two caps
Connection.
Innovative point of the present utility model is：
In plug and cap one muff 1 of outer coaxial package, the muff is made up of ceramic material, and the two ends of muff lead to
The glass cement 5 for crossing insulation is sealed.
Described B alloy wire be dilval silk, line footpath be 0.06～0.07mm, coiling 16～20 enclose.
Described muff can also adopt rubber or resin material to make.
Above-described is only preferred implementation of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of conceiving without departing from utility model, some deformations and improvement can also be made, these belong to this reality
With new protection domain.
