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 arc matrix (1) and a contact composite layer (3), wherein the pure-copper arc matrix (1) is a long strip shape. One end of the arc matrix (1) is a circular arc shape and an arc inner concave part (5) matched with the shape of the pure-copper arc matrix (1) is arranged on an upper end surface of the pure-copper arc matrix (1). A pair of right-angle connection plates (2) is vertically mounted on double sides of middle of the pure-copper arc matrix (1) symmetrically. A connection through hole (6) is opened on a left end of the right-angle connection plates (2). Wiring boards (4) are disposed on two sides of the pure-copper arc matrix (1) on one side of the right-angle connection plates (2). The contact composite layer (3) is arranged on an upper side of the other end of the pure-copper arc matrix (1). The contact provided by the utility model adopts composite moulding of pure copper and silver zinc-oxide materials, production cost is low; and the contact is environment friendly and non-toxic and has the advantages of good welding resistance and electric wear resistance, short arc time, high breaking performance and strong heavy-current surge resistant ability and arc-corrosion resistant ability.
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 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 relay to touch bridge welding and connect the silver layer contact, comprise fine copper curved base and contact composite bed, described fine copper curved base is strip, the one end be circular arc and thereon end face be furnished with the arc indent that matches with its shape, the middle bilateral symmetry of described fine copper curved base vertically is furnished with a pair of right-angle connecting plate, the left end of described right-angle connecting plate has a connecting through hole, the both sides of the fine copper curved base of one side of described right-angle connecting plate are equipped with plugboard, and the upside of the other end of described fine copper curved base 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 relay 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.
