SUSPENSION FOR ELECTROCHEMICAL TREATMENT OF CONTACT ELEMENTS OF REED RELAYS Russian patent published in 2020 - IPC C25D17/06 

FIELD: technological processes.

SUBSTANCE: invention relates to suspending appliances used for local application of galvanic coatings on small-size articles made from ferromagnetic materials, in particular, to contact parts of reed relays. Suspension for electrochemical treatment of contact elements of reed relays comprises magnetic system, parallel located at fixed distance from each other and made of nonmagnetic material flat base and two identical flat perforated plates with coaxial holes of round cross-section. On surface of working part of base in contact with contact parts there is copper foil with thickness of 50–100 mcm, between the foil and the nearest plate there is a perforated insert made of chemically resistant organic material with holes of round section, coaxial with the holes in the plates, at that the diameter of the holes inside insert is 2-3 times larger than the diameter of the holes inside the plates.

EFFECT: improved quality of galvanic coatings of contact-parts of reed switches.
