Description
Technical field
The utility model relates to a kind of classroom instruction instrument, is specifically related to a kind of magnetic-type light emitting diode teaching aid.
Background technology
Light emitting diode is a kind of components and parts more common in circuit, is made up of the LED chip through encapsulating and pair of pins.In classroom, teacher, when carrying out the electrophysics experimental demonstration of being correlated with, need often to be electrically connected, and finished product of LED is conveniently installed in the circuit board and designs, and is not suitable for demonstrating.In addition, present teacher is when demonstrating, and generally corresponding experiment teaching aid can only be arranged and line on dais, due to the relation at visual angle, students is difficult to see specific operation process and wiring clearly, affects teaching efficiency.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of light emitting diode teaching aid facilitating teaching demonstration.
For achieving the above object, the utility model provides following technical scheme: a kind of magnetic-type light emitting diode teaching aid, it is characterized in that comprising substrate, light emitting diode and a pairs of posts, described substrate is made up of the upper cover plate and base plate being provided with cavity, light emitting diode and a pairs of posts are fixedly plugged on upper cover plate, light emitting diode is connected by the wire be arranged in substrate cavity with a pairs of posts, and described cavity is by base plate capping.
Because the utility model Will light emitting diode is installed on one substrate, and be provided with a pairs of posts, therefore facilitate teacher or student to carry out line, and can Reusability.
The utility model is arranged further: the bottom surface of described base plate is provided with permanent magnet.All be provided with iron plate in blackboard due to present many schools, after substrate bottom surface is provided with permanent magnet, lamp socket teaching aid can directly adsorb on blackboard, is very easy to the observation of student to experimentation, is conducive to improving teaching efficiency.
The utility model is arranged further again: described binding post comprises conductive pole and set nut, on upper cover plate, relevant position is provided with through hole, trip bolt passes the upper surface of described through hole to upper cover plate from upper cover plate cavity, described lock-screw comprises insulation button, button lower surface is fixed with contact screw in insulation, conductive pole lower surface is provided with the screw matched with screw, conductive pole upper surface is provided with the screw matched with contact screw, and described conductive pole two ends are threaded with trip bolt and lock-screw respectively.By the setting of above-mentioned conductive pole, connecting wire and both can screw to compress with lock-screw and connects, can being directly electrically connected by being clipped in the conductive pole that is exposed at outside upper surface of base plate formed for the wire being provided with clip, very convenient.
Below in conjunction with accompanying drawing, the utility model is further described.
