Abstract
The utility model relates to a compound wire resistor ware that fuses fast, including plug, cap, lead wire, resistance wire, at the both ends of plug two caps of mirror symmetry spiral -lock, a lead wire is respectively connected to two caps, two conducting rings of interval symmetry suit on the plug between two caps, and the electrically conductive fusing liquid of coating one deck twines the resistance wire, at the outside of plug and cap cladding protective layer on the plug between two conducting rings on the plug between cap and conducting ring. This resistor twines the resistance wire at the both ends of plug, and after the both sides resistance wire generated heat, the heat focused on the middle part of plug, makes the electrically conductive fusing liquid thermal decomposition by heating who coats at the middle part, the branch breaking of contact, fast, in time.
Description
Technical field
This utility model belongs to resistance field, is related to wire resistor, especially a kind of compound quick fuse wire wound resistor.
Background technology
The structure of existing winding-type fuse-resistor is：The two ends of plug are cased with cap, and resistance wire is wound with plug,
The two ends of resistance wire are connected respectively with two blocks, and in plug, cap and resistance wire flame retardant paint is externally coated with.When by resistance
The current anomaly of device, and current value exceed its rated current it is larger when, resistance wire heating make resistor temperature be quickly raised to electricity
Resistance silk melting temperature, produced fusing before resistor surface and its surrounding carry out abundant heat exchange, played protection electricity
The purpose on road.
Generally resistance wire is uniformly wrapped on whole plug, can disperse heat, fusing is difficult, while plug also can disperse
Partial heat, so as to extend the fusing time of alloy wire, prevents resistor from fusing rapidly in the stipulated time, its harm for bringing
It is have the danger for burning out associated device and causing fire.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, there is provided a kind of scientific structure design is rational
Compound quick fuse wire wound resistor.
This utility model solves the technical scheme that adopted of technical problem：
A kind of compound quick fuse wire wound resistor, including plug, cap, lead, resistance wire, in the two ends mirror image of plug
The symmetrical cap of spiral-lock two, two caps respectively connect a lead, and two conducting rings of symmetrical suit are spaced on the plug between two caps,
The fusing liquid of one layer of conduction is coated on plug between two conducting rings, on the plug between cap and conducting ring resistance is wound
Silk, in the outside of plug and cap protective layer is coated.
And, described conducting ring is tin plating iron hoop.
And, the width of described conducting ring is 1.1～1.3mm.
And, the width of the cap is 1.4～1.6mm.
And, the winding width of the both sides resistance wire is 2.4～2.6mm, and coiling is 5～10 circles.
And, the coating width of the fusing liquid is 0.5～0.7mm.
Advantage of the present utility model and good effect are：
1st, this resistor winds resistance wire at the two ends of plug, and after the heating of both sides resistance wire, heat is focused in plug
Portion, makes to be coated in the conductive fusing liquid decomposes at middle part, disjunction circuit, quickly, in time.
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, there is electric fuse and resistance
Dual property.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and by specific embodiment the utility model is described in further detail, 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 compound quick fuse wire wound resistor, including plug 3, cap 2, lead 1, resistance wire 4, at the two ends of plug
The cap of specular spiral-lock two, two caps respectively connect a lead, symmetrical suit two are spaced on the plug between two caps conductive
Ring 6, coats the fusing liquid 7 of one layer of conduction on the plug between two conducting rings, twine on the plug between cap and conducting ring
Around resistance wire.Protective layer 5 is coated in the outside of plug and cap.
Described conducting ring is tin plating iron hoop, and the width of conducting ring is 1.1～1.3mm, and the width of the cap is 1.4
～1.6mm, the winding width of the both sides resistance wire is 2.4～2.6mm, and coiling is 5～10 circles.The painting of the fusing liquid
Width is covered for 0.5～0.7mm.
Described resistance wire is nickel filament.
Described plug is the white rod of ceramics of 3 × 10mm.
Operation principle of the present utility model is：
When larger more than its rated current by the current anomaly of resistor, and current value, the heating of both sides resistance wire, heat
Measure to middle concentration so that conductive fusing liquid decomposes, play open circuit, the effect of protection circuit.
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.
