Abstract
The present invention relates to a kind of quick fuse wire wound resistor; including plug, cap, lead, resistance wire; in two cap of both ends mirror symmetry spiral-lock of plug; two caps respectively connect a lead; a conducting ring is set with plug between two caps, resistance wire is wound on the plug between conducting ring and an end cap cover, fuse is connected between conducting ring and another end cap cover; the winding width of the resistance wire is the 1/4~2/3 of plug length volume, and protective layer is coated in the outside of plug and cap.This resistor only winds resistance wire in 1/4~2/3 length of plug, and heat is concentrated, is more rapidly fused.
Description
Technical field
The invention belongs to resistor field, is related to wire wound resistor, especially a kind of quick fuse wire wound resistor.
Background technology
The structure of existing winding-type fuse-resistor is：The both ends of plug are cased with cap, and resistance wire is wound with plug,
The both ends of resistance wire are connected with two blocks respectively, and flame retardant paint is externally coated with plug, cap and resistance wire.When passing through resistance
The current anomaly of device, and current value exceed its rated current it is larger when, resistance wire fever resistor temperature is quickly raised to electricity
Silk melting temperature is hindered, fusing is produced before resistor surface and its surrounding environment carry out abundant heat exchange, plays protection electricity
The purpose on road.
Usual resistance wire is uniformly wrapped on whole plug, can be disperseed heat, is not easy to fuse, while plug can also disperse
Partial heat, so as to extend the fusing time of alloy wire, prevents resistor from fusing rapidly in the stipulated time, its harm brought
It is to have the danger for burning out associated device and causing fire.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided the quick fuse that a kind of heating area is concentrated
Wire wound resistor.
The technical proposal for solving the technical problem of the invention is：
A kind of quick fuse wire wound resistor, including plug, cap, lead, resistance wire, in the both ends mirror symmetry of plug
Two cap of spiral-lock, two caps respectively connect a lead, a conducting ring are set with the plug between two caps, in conducting ring and one end
Resistance wire is wound on plug between cap, fuse is connected between conducting ring and another end cap cover, the resistance wire twines
Around 1/4~2/3 that width is plug length volume, protective layer is coated in the outside of plug and cap.
Moreover, the conducting ring is tin plating iron hoop, the width of conducting ring is 1.1~1.3mm.
Moreover, the resistance wire is nickel filament, winding turns are 15~20 circles.
The advantages and positive effects of the present invention are：
1st, this resistor only winds resistance wire in 1/4~2/3 length of plug, and heat is concentrated, is more rapidly melted
It is disconnected.
2nd, the design of this resistor structure is reasonable, is easy to mechanization production, can greatly improve production efficiency.
3rd, this resistor is mainly used in the main circuit of the electric appliances such as various chargers, instrument, there is fuse and resistance
Dual property.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following embodiments are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of quick fuse wire wound resistor, including plug 4, cap 1, lead 7, resistance wire 5, in the both ends mirror image of plug
Two cap of symmetrical spiral-lock, two caps respectively connect a lead, a conducting ring 3 are set with the plug between two caps, in conducting ring
Resistance wire is wound on plug between an end cap cover, fuse 2, the resistance are connected between conducting ring and another end cap cover
The winding width of silk is the 1/4~2/3 of plug length volume, and protective layer 6 is coated in the outside of plug and cap.
The 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 resistance wire is nickel filament, and winding turns are 15~20 circles.
The plug is the ceramic white rod of 3 × 10mm.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, on the premise of inventive concept is not departed from, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.
