Close after porcelain tube, the volume of whole resistor is big, and power is small, while heat dispersion is poor, while needing to add on porcelain tube adjustable
Ring, operates the mode controlled with regulation relatively complicated.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, there is provided a kind of new porcelain dish formula coiling
Resistor, the application in great-power electronic field is realized with smaller volume.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：A kind of new porcelain dish formula coiling
Resistor, includes ceramic skeleton, alloy wire, central rotating shaft, fastener, base, insulated terminal and brush；The fastener,
The central rotating shaft and fixed bit is concentric links together；The alloy wire is wound on the ceramic skeleton and forms resistance
Body, and high temperature resistant enamel paint is coated, it is bonded on the base；The brush and the insulated terminal are engaged on resistive element
On, wherein the brush needs to be driven by the central rotating shaft.
As a preferred embodiment, the ceramic skeleton and the alloy wire that the utility model is used are respectively the porcelain of annular
Disk and constantan line, while reaching high efficiency and heat radiation effect, reduce influence of the temperature to resistance value.
As a preferred embodiment, the resistive element that the alloy wire is constituted with the ceramic skeleton needs to coat the painting of high temperature resistant enamel
Material, reduces the abrasion of the alloy wire, effectively moistureproof.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
