US Patent 9980405 Electrical modules and modular electronic building systems

The present disclosure provides an electrical module and a modular building system including electrical modules. The electrical module includes a housing member including N pin portions and a connecting portion that connects the N pin portions, where N is greater than 1; N conduction members unconnected with each other; and N magnetic members. Each pin portion is a plate having a through-hole towards its thickness direction, and corresponds to one conduction member and one magnetic member. Each conduction member includes: a first part electrically connected with a lead of an electrical component; and a second part electrically connected with the corresponding magnetic member. Each magnetic member fills the through-hole of the corresponding pin portion, and establishes magnetic connection with a magnetic member of another electrical module in thickness direction to allow the two electrical modules to contact and rotate against each other using a contacting point as a rotation pivot.
