Description
Technical field
The utility model is related to a kind of circuit protecting element, especially a kind of fuse-resistor.
Background technology
Current fuse resistance realizes both there is fuse work(by the mode that resistor adds Thermal Cutoffs combined
It can need to integrate two in a product but also as the function of conventional resistor, such its complex manufacturing technology of design
Element, complex manufacturing technology, difficulty of processing is big, and production cost is high.
Fuse-resistor in the prior art needs to integrate two elements, and a such as Thermal Cutoffs adds a resistance two
It is encapsulated in again in ceramic case after kind element series connection and forms a fuse-resistor；Be for another example Thermal Cutoffs is passed through it is hollow
Copper cap sleeve is connected in hollow porcelain tube, then makes wire resistor in porcelain tube, principle is still then to use water again using concatenated mode
Mudding forms a fuse-resistor in ceramic case.Both technologies all use the series connection of two elements, the former makes
It obtains small product size to become larger, is unfavorable for radiating, influences the fusing performance of Thermal Cutoffs, and volume causes greatly installation space big,
It is not suitable for the requirement of miniaturization installation；The latter is socketed in Thermal Cutoffs in wire resistor, and volume is to become smaller, but corresponding
Manufacture craft become complicated.
Therefore need a kind of new technical solution to solve the above problems.
Utility model content
Purpose of utility model：A kind of fuse-resistor is provided, it is simple in structure, small and facilitate manufacture.
Technical solution：In order to achieve the above objectives, following technical solution can be used in the utility model fuse-resistor：
A kind of fuse-resistor, including：Insulation shell, is wrapped on insulating bar the insulating bar in insulation shell
Fuse, two foot pieces being connect with fuse both ends；The foot piece includes the arc ring body being located in insulation shell and from arc
Ring body extends the pin of insulation shell；The arc ring body be wrapped in the outer surface of insulating bar and the inside of arc ring body with
The fuse wire contacts being wrapped on insulating bar.
Advantageous effect：
The utility model no longer uses two kinds of concatenated thinkings of element in the prior art, but uses instead molten in insulating bar winding
The mode of silk adjusts diameter while fuse has fusing performance by the combination to sub-thread or multiply insulating bar
And the spacing size of fuse winding adjusts the overall length of fuse, realizing needs resistance value size to be achieved, realize resistor and
The function that both fuses have concurrently.In addition, the connection between foot piece and fuse no longer uses welding, but by way of pressing
Connection, manufacture is easy, while reducing welding and being good for the environment production.

Arc ring body 41 in insulation shell 1 and the pin 42 for extending insulation shell 1 from arc ring body 41.The arc ring body 41 is logical
Cross that pressing mode is wrapped in the outer surface of insulating bar 2 and the inside of arc ring body 41 connects with the fuse 3 being wrapped on insulating bar 2
It touches.In order to improve pressing effect, the arc ring body 41 is equipped with the reinforcing rib 43 being bonded with insulating bar.In the present embodiment,
The pin 42 is plug-in type pin.
In the present embodiment, insulating bar 2 is Fiber glass rod.It is formed by being combined by sub-thread or multiply glass wire
The mode that alloy fuse is spirally wound on Fiber glass rod can be by sub-thread while fuse has fusing performance
Or the combination of multiply insulating bar adjusts the overall length of fuse to adjust the spacing size of diameter and fuse winding, realizes
Resistance value size to be achieved is needed, realizes that the function that both resistor and fuse have concurrently realizes that both resistor and fuse have concurrently
Function.
The insulation shell is ceramic case or plastic housing.
Cement slurry or arc extinction slurry 5 are filled in the insulation shell.And cement slurry is starched for common cement resistor
The formula of material, main material are made of the material matings organic environmental-protection adhesive such as quartz sand and talcum powder and titanium dioxide.As selection is gone out
The scheme of the arc extinction slurry provided in Chinese patent ZL 201310610434.9 may be selected in arc slurry.
Embodiment two：
As shown in figure 3, for another example structure of fuse-resistor.The embodiment and the structure in embodiment one
It is roughly the same, it is unique it is different be that pin 42 is the plug-in type pin of another shape, also for being convenient for and circuit board
Contact fix.
Embodiment three：
As shown in figure 4, for another example structure of fuse-resistor.The embodiment and the structure in embodiment one
It is roughly the same, it is unique it is different be that pin 42 is the plug-in type pin of the third shape, which forms the shape of a fork
Shape is fixed also for convenient for the contact with circuit board.
