Abstract
The utility model discloses a circuit teaching appliance, which is a teaching tool used for the demonstration of the education of circuit accidence for pupils. Various circuits are fomred by that a power supply, a switch and a function block which are connected by conducting wires, pupils can further deepens the comprehension of the circuit principle by inserting and assembling the circuits, and the structure of the utility model is visual. The utility model helps the pupils to obtain elementary circuit knowledge, and helps the pupils to simultaneously cultivate the learning interest of the circuits; the utility model is a right-hand man used for increasing the pupils' operating ability and accidence education of electricity knowledge.
Description
The utility model relates to a kind of education demonstration equipment, is particularly useful for the pupil and begins to learn the Circuit teaching aid that circuit is used.
When modern primary school enters six grades, just begin the ushered-in education of electricity knowledge, can understand circuit intuitively, grasp the circuit rudimental knowledge for the ease of the student, it is very necessary that a kind of easy Circuit teaching aid is provided, at present, as the pupil educate a kind of image of usefulness, directly perceived, the convenient, fast Circuit teaching aid of safety again of pegging graft still belongs to shortcoming.
The purpose of this utility model is exactly to provide a kind of image, directly perceived, the convenient, fast Circuit teaching aid of safety again of pegging graft for pupil's circuit ushered-in education.
The utility model is realized by following technical proposal: this Circuit teaching aid connects into multiple circuit by power supply, switch, functional block with lead, and described switch comprises that socket and two mutual pegging graft of conduction inserted sheets with two jacks form; Described functional block comprises that the socket with two jacks, two conduction inserted sheets and mutual the pegging graft of display element form, and is provided with the jack of grafting display element on a conduction inserted sheet.
The utility model promptly becomes image, multiple safe Circuit teaching aid intuitively by the combination of pegging graft mutually of simple components and parts, by demonstration education, help the student obtaining just to cultivate the interest that circuit is learnt in the step circuit knowledge, and, be the competent assistant of electricity knowledge ushered-in education by the manipulative ability that self socket connection improves.

Embodiment to the utility model is described in detail again below with reference to above-mentioned accompanying drawing.
Circuit teaching aid (referring to Fig. 1-6) connects into multiple circuit by power supply (1), switch (2), functional block (4) with lead (3).
Described power supply (1) has the battery folder (6) of a long box-like, the two ends sidewall of battery folder has blade recepatcle, two flat conduction inserted sheets made of copper (5) are plugged in its jack, power is that the safe battery (not shown) of 1.5V is arranged in battery folder and contacts with the inserted sheet at two ends, promptly constitutes power supply.
Described switch (2) comprises the socket (9) with two parallel flat jacks, two be "
Type " copper conduction inserted sheet (8) be plugged in opposite directions in this jack and constitute switch, circuit turn-on when an end in contact of two conduction inserted sheets is realized by manual operation.
Described functional block (4) comprises the socket (12) with two parallel flat jacks, two be "
Type " copper conduction inserted sheet (10) be plugged in opposite directions in this jack, also have jack on one of them inserted sheet, make display element (11) be plugged in this jack and contact to constitute the functional block of conducting with another conduction inserted sheet.
Display element (11) can with luminous small electric bulb or the pronunciation chip, the luminous small electric bulb of present embodiment.
In the end wiring hole (7) of the conduction inserted sheet of the equal butting of lead of connection power supply, switch, functional block.Socket in the switch (9) is identical with socket (12) structure in the functional block, two kinds be "
Type " conduction inserted sheet structure similar substantially.
Utilize above-mentioned power supply, switch, functional block can connect into series circuit as Fig. 1; Or connect into parallel circuit as Fig. 2, if F place connects a switch again between these circuit two functional blocks, realizes that two functional blocks distinguish conductings or while conducting; Also can connect into series and parallel combinational circuit as Fig. 3.
Foregoing circuit is applicable to the pupil person that begins to learn the circuit, is easily understood, by student oneself assembling of pegging graft, more help to enhance memory and understand, and be that a kind of electricity ushered-in education is demonstrated indispensable educational outfit.
