This is a replacement part for the mounting blade of a Xiaomi Pet Water Fountain. This is the part with the pump attached, screwed to the drinking dish.
The original contacts corroded and stopped working after a year of use. Instead of replacing the perfectly working pump that are really great designed for long lifetime, this part can be soldered to the pump wires using VCN510-F-2-1.5 spring plungers (2mm diameter, 1.5mm retractable).
The curvature is not perfect and not watertight, so be careful when cleaning.
The author marked this model as their own original creation.
