Description
Technical field
The present invention relates to a kind of resistor, especially relate to a kind of flat aluminum alloy casing resistor.
Background technology
Mainly there is following problem in order widely used flat aluminum alloy casing resistor at present: the overall dimension size of resistive element micarex is identical with insulating concrete mica plate; Be positioned at the middle part of aluminum hull, when assembling, may be in obliquity or skew, in assembling process; The air gap has appearred between insulating concrete mica plate and the aluminum hull; Because the air gap makes the very high thermal resistance of generation between aluminum hull and mica sheet, resistor dispel the heat and is affected; Lead adopts welding manner to be connected with brace; In the welding process, lead is made up of strands of metal wire, and some wire is welded on the brace cmpletely during welding; Such solder joint connects and belongs to unstable solder joint connection; Use was lost efficacy easily and was snapped, and caused resistor to open circuit, and influenced the relevant device operate as normal.
Summary of the invention
The object of the invention is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of heat dispersion is even, withstand voltage properties stable, the flat aluminum alloy casing resistor of long service life
The object of the invention can be realized through following technical scheme:
A kind of flat aluminum alloy casing resistor; Comprise aluminum alloy casing, brace, resistance wire, mica sheet support, lead, lead terminal, said resistance wire is on the mica sheet support, and the mica sheet support is arranged in the aluminum alloy casing; Two end points of resistance wire are welded on the brace; Lead is connected with brace and is connected with resistance wire through brace, and the link of said lead and brace is fixed with the crimping metal circular tube, on lead, is with high temperature resistant silica gel insulating sleeve; This sleeve covers brace; The mica sheet support inserts the aluminum alloy casing that is provided with the insulation mica and reserves in the draw-in groove, and the lead that is with high temperature resistant silica gel insulating sleeve cover is fixed through fluid sealant, and said lead one end is connected with lead terminal.Insulating concrete mica plate in the described aluminum alloy casing is provided with draw-in groove, and the specification of the specification of draw-in groove and mica support is complementary.
Compared with prior art; The present invention has overcome the clearance issues of mica support and aluminum alloy casing through the insulating concrete mica plate draw-in groove in the aluminum alloy casing, solved fill by slurry inhomogeneous, the technical problem of the resistor job insecurity that is caused; And this is through the use of high temperature resistant silica gel insulating sleeve; Solved resistor withstand voltage properties problem, also played the guardwire effect, the use of circular crimping metal circular tube; Lead fully is connected with brace, guarantees the use of resistor long-time continuous.
