Abstract

The invention discloses a welding method for a relay contact reed assembly. According to the welding method, a clamping method of an original clamp is changed, and dimension requirements for each position of the contact reed assembly are guaranteed; a traditional welding method of a thin piece and a thick piece is changed, and the thick piece is taken as a main welding face; a traditional welding method employing tungsten copper alloy, chromium zirconium copper alloy and beryllium cobalt copper alloy as electrode materials to weld nickel silver and a silver magnesium nickel assembly is changed, and silver copper alloy and silver chromium alloy are taken as electrode tips to weld the nickel silver and the silver magnesium nickel reed assembly; problems of overhigh temperature of bonding and welding areas of the reed assembly and an electrode in a long term are solved, and burn damage to the reed assembly caused by the electrode in a welding process and crystal boundary organization change are greatly reduced.

Description

technical field

[0001] The invention belongs to the field of welding technology, in particular to a welding method for a relay contact reed assembly. Background technique

[0002] The contact reed component is a very important component in the relay. In many small and precision sealed relays, one end of the silver-magnesium-nickel sheet is directly used as the current contact and provides a certain contact pressure for the contact. The other end of the sheet is connected to the wrap angle and The seat plate terminal is welded, and the contact spring and the connection angle are usually connected by spot welding, such as Figure 5 , Image 6 and Figure 7 As shown, including the contact reed and the welding wrap angle, the left end of the contact reed has a terminal, the right end of the welding wrap angle has a seat plate terminal, and the right end of the welding wrap angle is in contact. This area is the welding area. The relative position and size of the parts in the as...
