Abstract
The utility model relates to a welding silver-layer contact for a thermostat 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 rods (4) are symmetrically arranged on two sides of one end of the pure copper matrix (1) and two long-strip inner concave parts (5) are mounted on an upper end surface on the same end side by side. The contact composite layer (2) is disposed on an upper end surface of the other end of the pure copper matrix (1). The contact provided by the utility model adopts pure copper and silver zinc oxide materials to carry out composite forming, has the advantages of low production cost, environmental protection and non-toxic property, fusion welding resistance, good electrical wearing property, short arcing time, high breaking performance, high heavy current surge resistant capacity and strong arc-corrosion resistant capacity.
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 thermostat 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 thermostat and connects the silver layer contact, fine copper and the composite molding of Ag-ZnO material have been adopted, production cost is low, environment-protecting asepsis, have anti-melting welding, anti-electrical wear is good, arcing time is short, and interrupting performance height, Chinese People's Anti-Japanese Military and Political College's rush of current ability and anti electric arc corrosion ability are strong.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of thermostat 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 bilateral symmetry of one end is equipped with connecting rod and is arranged side by side with two strip indents in the upper surface of same end, and the upper surface 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 Ag-ZnO (AgZnO).
Ag-ZnO (AgZnO) environment-protecting asepsis has anti-melting welding, anti-electrical wear is good, and the arcing time is short, interrupting performance height, the characteristics that Chinese People's Anti-Japanese Military and Political College's rush of current ability is strong.Compare with Agcdo (AgCdO) contact material and to have better resistance fusion welding, under the breaking current condition of 3000~5000A, have more preferably anti electric arc corrosion ability.
Beneficial effect
The utility model relates to provides the tactile bridge welding of a kind of thermostat to connect the silver layer contact, fine copper and the composite molding of Ag-ZnO material have been adopted, production cost is low, environment-protecting asepsis, have anti-melting welding, anti-electrical wear is good, arcing time is short, and interrupting performance height, Chinese People's Anti-Japanese Military and Political College's rush of current ability and anti electric arc corrosion ability are strong, be mainly used in rated current at 200A with interior medium and small capacity low pressure relay.
