VISUAL TRAINING APPLIANCE L-MICRO FOR STUDYING ELECTRIC OCCURRENCES Russian patent published in 2007 - IPC G09B23/18 

FIELD: training appliances, possible use as training visual equipment for demonstrating and studying physical and electric events.

SUBSTANCE: training visual appliance L-micro for studying electric occurrences includes mounting table, made of magneto-conductive sheet, a set of boards, provided with magnetic strips on base and having electric sockets on facial side, while mounted on appropriate boards are, respectively, current source, electric key, resistors of constant and alternating resistance, sink with electrodes, electric lamps, and appliance is provided with electric wires, used for facilitating assembly of appliance elements in form of certain electric circuit and made with possible fastening in electric sockets by means of pins provided on ends. Device is different due to each board being made in form of box, internal hollow of which is divided on edge, central and middle sections, provided with cylindrical branch pipes, made with through apertures and positioned inside sections of box in rows, while in middle sections body walls are provided - rigidity ribs, part of which is made truncated for one third of box height, while branch pipes of middle sections are positioned between truncated walls and are also truncated for one third of box, while magnetic strips are made in form of inserts held in niche formed by truncated walls and truncated branch pipes, branch pipes of edge sections and central section being made of greater diameter than branch pipes of middle sections, and between branch pipes of central section branch pipes are positioned with diameter, equal to diameter of truncated branch pipes, while appliance is additionally provided with compass, coil made in form of reel with wire wound spirally on the frame, while output ends of coil wires are equipped with contact clamps, and each electric lamp is provided with cap positioned above it and held on branch pipe of board by means of post, which cap is made in form of spherical segments, while electrodes of sink are made in form of plates with bent ζ-like spring ends, meant for fastening in the sink, and current source is made in form of electric engine with output shaft, on which a pinion gear is mounted by means of nave box external shape of which is made cross-like and mounted on which by means of collet grip nave with internal cross-shaped mounting aperture and longitudinal diametric groove slit is driving wheel provided with bearing rib.

EFFECT: simplified mounting and dismounting, increased reliability, safety and comfort of usage.
