Problems solved by technology

At present, the initial pressure and reed stiffness test in the relay contact spring system mostly use the relay suction reaction force test system. The suction reaction force test system is mainly for the test device of the whole relay, and is used for the test of the contact spring system of small sealed electromagnetic relays. , must undergo necessary modification, and the operation versatility is low; secondly, because the test system is relatively complex and takes a long time to test a single piece, it cannot meet the efficiency requirements of batch testing on the production line; The accuracy is fixed, and the test flexibility of reeds with different stiffnesses (the peak force range covers 0.5~5N) under certain accuracy requirements is low
