The utility model has the beneficial effects that with the adoption of the technical scheme, the brass alloy material has good electric conduction property, good heat-conducting property, low and stable contact resistance, high corrosion resistance and good fusion welding resistance property, can be repeatedly operated and used in the vehicle electric appliance and is usually used in the electric appliance which is frequently operated and used, such as a brake lamp switch, a window switch and the like of a car.
Description
Technical field
The utility model relates to the electrical contact material technical field, is specifically related to the multiple ag material of a kind of copper.
Background technology
Touching bridge is applied to touch bridge and be provided with contact in the various contactors usually.Electric contact on the contact is the contact element of appliance switch, mainly undertaking connection, open circuit, reach the task of connection, disconnecting consumers electric current, electric contact and arc quenching system are the hearts of appliance switch, the fail safe of appliance switch, reliability and cut-off and close and close physical property and the electrical characteristics thereof that characteristic depends on electric contact material to a great extent.Therefore the performance of electric contact material directly affects the reliability service of appliance switch and associated electrical appliance equipment.
Mostly use copper-based material in the existing electric contact production, existing copper-based material major part is made up of materials such as copper, tungsten and tungsten carbides.Have the advantages that breaking capacity is higher, electrocorrosion-resisting is better, anti-melting welding ability is strong, cut-off current is lower.But high speed development along with modernization construction, high voltage power transmission and transforming networking load increases day by day, device for switching develops towards more high voltage, bigger capacity direction, and original electric contact is slightly inadequate at aspects such as breaking capacity, electrocorrosion-resisting, anti-melting welding ability, cut-off currents.
The utility model content
The purpose of this utility model is to provide the embedding of a kind of alloyed copper copper multiple silver-colored car electrics material, solves above technical problem.
The technical problem that the utility model solved can realize by the following technical solutions:
The multiple silver-colored car electrics material of a kind of alloyed copper copper embedding comprises a brass sheet material matrix, it is characterized in that, described brass sheet material matrix is provided with location notch, described location notch is provided with silver bar, and described silver bar melts admittedly on described location notch, and is into a single integrated structure with described brass sheet material matrix.Make silver content reach standard with silver bar and brass sheet material matrix are molten admittedly together, make to the utlity model has excellent conducting performance, low and stable contact resistance, high erosion resisting, resistance fusion welding and can wait advantage by force.
Described location notch is set to two location notchs, and described two location notchs are separately positioned on the place, two edges of described brass sheet material matrix.Adopt above-mentioned technology, make and touch bridge and contact is connected as a single entity, can in car electrics, use by frequent movement,, use in the electrical equipment of frequent action such as car window switch generally as the car brake lamp switch.
Described silver bar can adopt welding and sintering and described brass sheet material matrix to be melt into one admittedly.By the sintering diffusion technology, make these two kinds of metals of silver bar and brass sheet material matrix produce solid clinkering and close, in the hope of reaching best bond strength, after the sintering diffusion, also can make product produce work hardening, in the hope of reaching best modulus of elasticity by technologies such as pre-cold rolling and pinch passes.
Described brass sheet material matrix adopting 62 brass sheetes.So that the content of copper reaches standard, guarantee heat conduction of the present utility model and electric conductivity.
Beneficial effect: owing to adopt technique scheme, the utlity model has excellent conducting performance, good heat-conducting, low and stable contact resistance, high erosion resisting, resistance fusion welding energy by force, can in car electrics, use by frequent movement, generally, use in the electrical equipment of frequent action such as car window switch as the car brake lamp switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, the multiple silver-colored car electrics material of a kind of alloyed copper copper embedding comprises a brass sheet material matrix 1, preferred 62 brass sheetes, brass sheet material matrix 1 is provided with location notch, and location notch is provided with silver bar 2, and silver bar 2 is melt into one admittedly by welding and sintering technology and brass sheet material matrix 1.Location notch is set to two location notchs, article two, location notch is separately positioned on the place, two edges of brass sheet material matrix 1, preferably the edge on 1 liang of long limit of brass sheet material matrix is provided with location notch, silver bar 2 just melts two length limit edges at brass sheet material matrix 1 admittedly like this, with silver bar 2 and brass sheet material matrix 1 solid melting together, make silver content reach standard, make the multiple silver-colored car electrics material of a kind of alloyed copper copper embedding have excellent conducting performance, low and stable contact resistance, high erosion resisting, resistance fusion welding and can wait advantage by force.Adopt above-mentioned technology, also make and touch bridge and contact is connected as a single entity, can in car electrics, use by frequent movement,, use in the electrical equipment of frequent action such as car window switch generally as the car brake lamp switch.
Brass sheet material matrix 1 and silver bar 2 solid molten can employings by argon arc welding and sintering diffusion technology, the face that meets with brass sheet material matrix 1 during welding carries out wiping with alcohol and white gauze, and use the argon arc welding procedure that silver bar 2 is welded on the location notch of brass sheet material matrix 1 two edges, obtain base substrate; Sintering process: as in the heating furnace, under protective atmosphere, adopt intermediate frequency three-temperature-zone gradient distribution temperature sintering diffusion technology to carry out presintering, base substrate so that obtain better combined strength bination; Sintering process carries out in reducing atmosphere or vacuum atmosphere, in case oxidation.Heating furnace is suitable for the employing electric furnace, is suitable for especially and adopts the molybdenum filament sintering furnace, and the molybdenum filament sintering furnace has temperature stabilization and is suitable for the characteristics of control.Charge into reducing gases in the molybdenum filament sintering furnace, reducing gases adopts hydrogen or nitrogen, the protective gas during as sintering.Also can charge into hydrogen and nitrogen simultaneously.The bond strength that the utlity model has the best that adopts above-mentioned technology to make.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
