Various circuits can be formed by the building blocks, and the inserting connection is convenient.

Description

Building block type electronic experiment box

The utility model relates to plug-in electronics experimental article.

Be used to the electronic experiment apparatus complex structure of imparting knowledge to students in the prior art, complex operation, annexation is not understood, and children's electronic toy intellectual, interesting poor.

The purpose of this utility model provides a kind of Experiment of Electronic Circuits that promptly can be used as, and can be used as the brick pattern electronic experiment box of children's electronic building blocks again.

The purpose of this utility model realizes by following measure, this experiment box is made of the building block of substrate and grafting with it, the convex inserting column 19 that is equally spaced is arranged on the substrate 18, have in the building block and the corresponding element of electronic original part symbol, there is double buckle 20 the building block end as the grafting node, building block comprises the single-unit piece, binodal piece 2 and the straight plate of three joint pieces, be shaped as board-type, and set square, the Square consisting of two isosceles right-angled triangles type, the building block of power supply tuned circuit and loudspeaker is the imitative type structure of element, and the edge part between the building block node is an inner concave shape, and the electronic building blocks piece is by grafting synoptic diagram layering grafting forming circuit modular construction.Building block connected structure with series connection grafting lead two joint pieces 2 between power module 1, keyswitch 5 and the bulb piece 4 and lead three joint pieces formation lighting circuits.Pull out when leading to keyswitch piece 5, the miniature bulb on the bulb piece 4 is luminous.

The node 1 of integrated circuit block 7 and node 2 pass through lead piece socket power piece and loudspeaker piece 6, grafting keyswitch piece between the node 4 of integrated circuit block 7 and the lead piece, the connected structure of formation warning circuit.During the connecing the bond switching piece and pull out out of this circuit, the element of loudspeaker piece 6 sends alerting signal.

Pass through lead piece socket power piece between the node 1 of integrated circuit block and the node 3, its node 1 is linked to each other by the lead piece with node 2, its node 2 grafting light-emitting diodes plumber blocks 8, the base node of another termination triode piece 12 of light emitting diode 8, the emission collection node of triode piece 12 connects the node 4 that connects integrated circuit block behind the capacitor block 9 by the lead piece, an end node of socket power after the emitter node of triode piece 12 links to each other with collector node, the collector node of triode piece 12 connects the base node of another triode piece 11, the emitter node series connection socket power piece of triode 11, keyswitch piece and motor piece 10, connect the collector node of triode piece 11 then, one end of motor piece 10 connects an end node of capacitor block 9 by the lead piece, constitutes the building block connected structure of dual power supply blocking circuit.When the keyswitch piece is connected, supply with warning integrated circuit (IC) 2 by one of them power supply, make this circuit send intermittently signal, amplify for two three utmost points again, the small machine that promotes on the motor piece 10 is done intermittently to rotate.

The node 1 of integrated circuit block 15 and node 4 are by lead piece series connection grafting microphone piece 13 and capacitor block, grafting light-emitting diodes plumber block 8 between its node 2 and the node 3, grafting resistance bolck 14 between light-emitting diodes plumber block 8 and the capacitor block, series connection grafting diode piece 17 and tuned circuit piece 16 between the node 2 of integrated circuit block 15 and the node 3, series connection grafting keyswitch piece and two power modules between its node 4 and the node 2 constitute radio broadcasting radio station circuit building blocks connected structure.The little microphone convert signals of sound on the tube piece 13 of living, send into integrated circuit (IC) 4 and carry out the voice frequency amplification, give diode from output terminal and carry out detection, sound signal after the detection produces many harmonic waves and has the tone signal composition simultaneously, again through the tuned circuit frequency-selecting, after tuned circuit piece 16 is launched frequency electromagnetic waves in the air as aerial coil office, nigh radio just can be received radio signal and sound.

The demarcation letter on electronic building blocks piece surface is by GB requirement signal, and integrated circuit is IC, and diode is VD, and light emitting diode is VL, and electric capacity is C, triode is VT, and motor is M, and keyswitch is SA, and power supply is G, and resistance is R, microphone is BM, and tuned circuit is CL, and loudspeaker is BL, and bulb is EL.
