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 pure copper arc matrix (1) is arc-shaped and an arc inner concave part (5) matched with a shape of the pure copper arc matrix (1) is mounted on an upper end surface of the pure copper arc matrix (1). A right-angle connection board (2) is vertically disposed on one side of middle of the pure copper arc matrix (1). Wiring boards (4) are disposed on two sides of the pure-copper arc matrix (1) on one side of the right-angle connection plate (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 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

A kind of relay touches bridge welding and connects the silver layer contact

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 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, centre one side of described fine copper curved base vertically is furnished with a right-angle connecting plate, 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 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, 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.
