As for the stainless steel sheet type resistor, each stainless steel conducting ring is provided with one boss on which one resistor sheet is just positioned, and the resistor sheets are prevented from shifting vertically to cut a mica pipe in a vibration environment, therefore, the mechanical strength and the vibration resistance are improved.
Description
Technical field
The utility model relates to a kind of resistor, relates in particular to a kind of stainless steel chip resistor.
Background technology
Existing stainless steel chip resistor, resistor disc is formed by the Digit Control Machine Tool punch process, and the resistor disc two ends are fastening with the stainless steel clamp bar.Be serially connected by stainless steel conducting ring, ceramic ring and standing screw, the cover micanite pipe plays insulating effect on the standing screw.The shortcoming of this structure is: it is poor that 1, stainless steel clamps the steel bar fastening force, comes off easily, also has withstand voltage Insulation Problems; 2, this structure anti-vibration performance is poor, and the micanite pipe cracky causes withstand voltage puncture; 3, between stainless steel conducting ring and stainless steel substrates under salt mist environment, electrochemical corrosion easily takes place.In addition, the resistor of this structure uses in the higher occasion of environmental requirement, as offshore wind farm, on the harbour machinery, uses under adverse circumstances for a long time, and the risk of inefficacy is arranged, and useful life is short.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of stainless steel chip resistor, improves mechanical strength and freedom from vibration.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of stainless steel chip resistor, comprise the multi-disc resistor disc, described resistor disc is serially connected by stainless steel conducting ring and ceramic ring, wherein, described stainless steel conducting ring is provided with boss, every sheet resistor sheet is positioned on the boss, and the multi-disc resistor disc links to each other by the riveted joint of mica clamp bar is fastening.
Above-mentioned stainless steel chip resistor, wherein, described stainless steel conducting ring plating nickel on surface.
Above-mentioned stainless steel chip resistor, wherein, described resistive element device up and down respectively clamping bottom mica strip and top mica strip are arranged.
Above-mentioned stainless steel chip resistor, wherein, there is the support base mica strip described resistive element device below.
Above-mentioned stainless steel chip resistor, wherein, described micanite pipe and screw rod gummed are made one.
The utility model contrast prior art has following beneficial effect: the stainless steel chip resistor that the utility model provides, by boss being set at the stainless steel conducting ring, above resistor disc just drops on, under vibration environment, avoid resistor disc to collect together up and down micanite pipe is cut, thereby improve mechanical strength and freedom from vibration.In addition, the stainless steel chip resistor that utility model provides at rust steel conducting ring plating nickel on surface, further guarantees good being electrically connected, and prevents electrochemical corrosion.

See also Fig. 1 and Fig. 2, the stainless steel chip resistor packages that the utility model provides is drawn together multi-disc resistor disc 8, described resistor disc 8 is serially connected by stainless steel conducting ring 4 and ceramic ring 5, wherein, described stainless steel conducting ring 5 is provided with boss 10, every sheet resistor sheet 8 is positioned on the boss 10, and multi-disc resistor disc 8 is by fastening linking to each other of mica clamp bar 9 riveted joints.
Resistor disc 8 processes towards mode by number, plays fastening effect with mica clamp bar 9 usefulness rivets up and down, and resistor disc 8 links together in the mode of connecting with resistor disc 8 usefulness stainless steel conducting rings 4 and porcelain ring 5.Compose one micanite pipe 7 and pass stainless steel conducting ring 4, porcelain ring 5 and resistor disc 8 respectively, play being fastenedly connected and insulating effect with screw rod 6.
The stainless steel chip resistor that the utility model provides, every sheet resistor sheet 8 usefulness numbers dash processing, and are fastening with mica clamp bar 9, resistor disc specification 110mm*350mm, 181.5mm*328mm, thickness 1mm.
In order to make stainless steel chip resistor disc that better freedom from vibration be arranged, on the structure of conducting ring 4, make modification, boss 10 designs are set, resistor disc 8 just drops on above the boss 10, and resistor disc 8 is not collected together up and down and can be cut micanite pipe 7 under vibration environment; Micanite pipe 7 is made of one with standing screw 6 on the other hand, and the full tooth screw mandrel of screw rod 6 usefulness above the viscose glue mica paper in layer is wrapped in, after the process series of process completes, exceeds a lot before the strength ratio; There is support base mica strip 3 described resistive element device below, suppresses vibration.
In order to make the anti-salt fog grade that improves product, avoid being electrically connected the position corrosion, conducting ring 4 is done Nickel Plating Treatment, guarantees good being electrically connected, and electrochemical corrosion can not take place.
The utility model has the advantages that vibration resistance can reach 3M6(IEC 60721-3-3:2002 well) standard more than, red rust does not appear in the above current-carrying part of 3 grades of alternation salt fogs of salt spray resistance (IEC 68-2-52:1996).
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
