摘要

A device perfected didactic experimentation, which is characterized by comprising the installation on a work table in a preferably inclined position, the assembly of a broad board of insulating material of high immunity to electrical conduction in which they are distributed in an orderly manner and grid, a multiple succession of perforations in which is drilled in each of them, a conductive metal sheath, consisting of a cylindrical bushing with smooth internal surface and with a thread area in the peripheral lower part, destined to receive in it the draft and fastening by nut and jam nut of a flat sheet metal conductive that establishes the unión of one of these sockets with one or other of the immediate ones, giving rise to the formation in the rear face of the board, of a network does not continue with suitable contact commas to carry out the circuit closure of a grouping of such contact sockets, remaining n independence from other grouped cores in the same board, whose dimensional capacity will be rather wide than restricted.
