Abstract: The present invention relates to a device for the experimental arrangement of electronic circuits with a built-in power distributor, which is self-locking to other of electronic circuits experimental devices. The power distributor of the device receives a stabilized first voltage through a socket of any type from any external device providing compatible output, creates a second voltage from the first voltage and supplies the first and/or the second voltage to the electronic circuit experimental device. The latter can be secured through 3D connectors which are compatible with 3D connection elements of other experimental electronics devices circuits. In alternative implementations the power distributor can include also some of a voltage regulator, a voltage selector, a dimmer, a voltmeter, an ammeter and a battery.

Abstract: A self-locking portable power distributor for breadboards has a power input, and a power output with two conductive lines, configured for supplying voltage and ground to at least one breadboard. The distributor includes at least one three-dimensional connection element located on a distributor first outer surface such that the distributor three-dimensional connection element is shaped and dimensioned to be compatible with at least one three-dimensional connection element of the breadboard. The breadboard three-dimensional connection element may be located on a breadboard first outer surface disposed substantially perpendicular to a breadboard second outer surface. The second outer surface of the breadboard may carry at least one electronic component terminal socket.
