CONTACT DEVICE AND METHOD OF ITS FABRICATION Russian patent published in 2009 - IPC H01H1/38 H01H11/04 

FIELD: instrument making.

SUBSTANCE: invention relates to aircraft instrument making and machine building. Proposed contact device comprises at least three flexible wire U-shapes two-leg contacts with flexible part. Aforesaid three contacts are bent in two mutually perpendicular planes (in contact plane and in plane perpendicular to the latter). These contacts are fitted in contact holder outside part and oriented inside contact holder along the radius towards its axis of symmetry, the contact both legs being soldered to contact holder. Method of fabricating contact device comprises producing wire contacts and contact holder by mechanical processing and bending followed by assembling, soldering and thermal treatment. Note here that contact bending and leg soldering are performed with contacts as-delivered, while thermal treatment includes heating after soldering at 350°C for 30 minutes, combining ageing and stabilising treatment in one cycle.

EFFECT: improved physical-mechanical properties, higher stability and ease of manufacture.
