Abstract
The utility model relates to a three-layer composite contact made of pure copper and a silver compound, which comprises a pure copper substrate, a silver compound composite layer and an opposite side composite layer, wherein the pure copper substrate comprises a cylindrical head and a cylindrical leg thinner than the cylindrical head, the silver compound composite layer is composited to one end of the cylindrical head of the pure copper substrate, the opposite side composite layer is composited to one end of the cylindrical leg of the pure copper substrate, and the compound of the silver compound composite layer is made of silver tin oxide. The three-layer composite contact formed by compositing the silver tin oxide and the pure copper is low in production cost, has excellent fusion welding resistance performance and electrical wear resistance performance and is widely applied to medium-capacity and high-capacity alternating-current contactors, high-power alternating-current switches, direct-current contactors, alternating (direct)-current power relays, automotive electric appliances and medium-capacity and low-capacity low-voltage circuit breakers.
Description
Technical field
The utility model relates to electronic devices and components and uses the field, contact, particularly relates to a kind of three composite contacts that adopt fine copper and silver compound.
Background technology
The contact is an element commonly used in the various electronic devices and components, and very high to its performance demands though its volume is little, composite contact has wide range of applications and usually uses precious metal material, generally adopts manual rivet and automatic riveting.Be composite contact in the market with fine silver; But fine silver intensity is low, hardness is low, resistance fusion welding and anti-electrical arc erosion performance are low; And consumption is big, cost an arm and a leg, and production cost is high, can only be applied in radio, communication with fields such as microswitch and little electric current electrical equipment.
The utility model content
The utility model technical problem to be solved provides a kind of three composite contacts that adopt fine copper and silver compound, has adopted fine copper and silver tin oxide material composite molding, and production cost is low, has good resistance fusion welding ability and anti-electric abrasioning performance.
The utility model solves the technical scheme that its technical problem adopted: a kind of three composite contacts that adopt fine copper and silver compound are provided; Comprise fine copper matrix, silver compound composite bed and offside composite bed; Described fine copper matrix is made up of cylindric head and cylindric foot; The thickness of described cylindric head is greater than the thickness of cylindric foot; The silver compound composite bed is compound in cylindric head one end of fine copper matrix, and said offside composite bed is compound in cylindric foot one end of fine copper matrix.
The thickness of described head composite bed is 0.2mm～0.6mm, the thickness 0.2mm～0.6mm of described foot composite bed.
Described composite bed compound is siller tin oxide (AgSnO
2).
Because tin oxide (SnO
2) have very high thermal stability, under the high arc temperature effect, be difficult for decomposing tin oxide (SnO
2) particle suspension in the molten bath of Ag, the viscosity of motlten metal is increased, difficult generation is splashed, so siller tin oxide (AgSnO
2) material has good, stable resistance fusion welding and good anti electric arc corrosion ability.
Beneficial effect
The utility model relates to provides a kind of three composite contacts that adopt fine copper and silver compound; Fine copper and silver tin oxide material composite molding have been adopted; The characteristics that utilized high, the very high thermal stability of siller tin oxide conductance, under the high arc temperature effect, be difficult for decomposition, contact resistance are low and stable; Have good, stable resistance fusion welding and good anti electric arc corrosion ability, big Capacity AC Contactor, high power AC switch, D.C. contactor, friendship (directly) stream power relay, car electrics and medium and small capacity low pressure circuit breaker in being mainly used in.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1; The execution mode of the utility model relates to a kind of three composite contacts that adopt fine copper and silver compound; Comprise fine copper matrix 2, silver compound composite bed 1 and offside composite bed 3, described fine copper matrix 2 is made up of cylindric head and cylindric foot, and the thickness of described cylindric head is greater than the thickness of cylindric foot; Silver compound composite bed 1 is compound in cylindric head one end of fine copper matrix 2, and said offside composite bed 3 is compound in cylindric foot one end of fine copper matrix 2., the thickness of described head composite bed and foot's composite bed is 0.2mm～0.6mm, and described composite bed compound is siller tin oxide (AgSnO
2).
The main processing technology of the utility model is compound cold-heading, siller tin oxide (AgSnO
2) and the silk material of two kinds of materials of fine copper under the cold headers impulsive force, two kinds of metals form radial plastic deformations and form the rammer shapes.
