Title: Adjusting one side clamped contact springs - uses storage of adjusted contact springs characteristics and rated curve accommodation
Inventor: MONAT HERMANN
IPC: H01H11/04
Filed: 1976-02-18
Abstract: The contract spring adjustment is carried out by deflecting the free spring ends up to stressing a given cross-sectional region beyond its elasticity strength. Simultaneously a reference spring with excessive is deflected and released by a controllable sensor of a measuring force pick-up. This spring movement is monitored by force-path measuring. The result is recorded as the spring characteristic and compared with the desired one. When the same value has been attained in both characteristics, the moving element of the pick-up is cut off, as in 2549894. The characteristic of the spring to be adjusted is recorded in a memory. If the recorded characteristic differs from the reference by a preset value, the reference has to be corrected.
