Abstract
The utility model relates to a welding silver layer contact for a relay contact bridge. The welding silver layer contact comprises a pure copper matrix (1) and a contact composite layer (2), wherein the pure copper matrix (1) is a long strip shape. Two connection holes (4) are opened on one end of the pure copper matrix (1) side by side and inserted boards (3) are vertically mounted on two sides of a middle position of the pure copper matrix (1). The contact composite layer (2) is arranged on an upper side of the other end of the pure copper matrix (1). The contact adopts pure copper and silver-nickel materials to carry out composite moulding, production cost is low, conductivity is high, contact resistance is low and stable, the welding silver-layer contact has excellent fusion welding resistant performance and electric wear resistant performance under intermediate and small current, and material transfer is relatively little under a DC condition.
Description
Technical field
The utility model relates to electronic devices and components and uses the field, contact, particularly relates to the tactile bridge welding of a kind of relay and connects the silver layer contact.
Background technology
The contact is 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.The contact mainly is used in the common electrical elements such as relay, thermostat, the material of contact generally all is to adopt low metal material or the alloy material of resistivity, mostly in the market is composite contacts of using 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, expensive, the production cost height can only be applied in radio, communication with fields such as microswitch and little electric current electrical equipment.
The utility model content
Technical problem to be solved in the utility model provides the tactile bridge welding of a kind of relay and connects the silver layer contact, fine copper and silver-colored nickel material composite molding have been adopted, production cost is low, conductance height, contact resistance are low and stable, have good resistance fusion welding energy and anti-electric abrasioning performance under the medium and small electric current, material transfer is less under the DC condition.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of relay to touch bridge welding and connect the silver layer contact, comprise fine copper matrix and contact composite bed, described fine copper matrix is strip, the one end has two connecting holes side by side, the middle both sides of described fine copper matrix vertically are furnished with plugboard, and the upside of the other end of described fine copper matrix is furnished with the contact composite bed.
The thickness of described contact composite bed is 0.4mm.
Described contact composite bed is to be made by silver-colored nickel (AgNi).
Beneficial effect
The utility model relates to provides the tactile bridge welding of a kind of relay to connect the silver layer contact, adopt fine copper and silver-colored nickel material composite molding, production cost is low, and conductance height, contact resistance are low and stable, have good resistance fusion welding energy and anti-electric abrasioning performance under the medium and small electric current, material transfer is less under the DC condition.
