Description

Screw-hole type electronic experiment plate

The utility model relates to a kind of electronic experiment plate, specifically belongs to a kind of screw-hole type electronic experiment plate that the electronic circuit wiring connects experiment that carries out.

Generally when carrying out electronic circuitry design, will carry out wiring earlier and connect experiment, especially school is at the enlightening stage of electronic technology teaching, the professor student carries out, when sub-line layout connects experimental implementation, owing to must weld by means of electric soldering iron, both dangerous also inconvenient.Just must use a whole set of instrument and materials such as 220V AC power, Iron Stand, welding rod, solder flux because use electric soldering iron, teaching unit is in the face of tens students of a class, to prepare enough the enough troubles of many cover articles for use simultaneously, solder technology is if also be difficult to grasp without uninteresting training of a period of time quickly still more, thereby is difficult to stop unsafe factor.Yet do not use these basic teaching aids, be difficult to help the student to grasp basic electronics knowledge again, improve manipulative ability.

The purpose of this utility model is to overcome the not only dangerous but also inconvenient drawback of existing electronic experiment plate, and a kind of screw-hole type electronic experiment plate is provided, and it can save a whole set of complicated instrument and materials such as power supply, Iron Stand, welding rod, solder flux, easy to use and safety.

For achieving the above object, the utility model provides a kind of screw-hole type electronic experiment plate, and it comprises a substrate of being made by insulating material, is characterized in: offer a plurality of screws of specializing in the screw location above it in advance; Described screw is fitly to be arranged on the substrate.

Above-mentioned screw-hole type electronic experiment plate, wherein, the upper diameter of described screw is that right cylinder, bottom are the shrinkage pool of cone greater than lower diameter and form a top.

The utility model is owing to adopt technique scheme, the learner is without electric soldering iron, only use a Phillips screwdriver and scissors, utilize screw prefabricated on screw and the screw plate just can be directly the pin of electronic component or lead to be carried out some simple interesting electronic circuits and be connected, be highly suitable for the formative education of electronic technology.Not only save trouble, also can make the teenager exempt the pollution of steam such as lead, tin metal and solder flux, can save the energy again with electric soldering iron, and cheap, be easy to popularize and promote.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is the partial view of the utility model bottom surface;

Fig. 4 is a partial sectional view of the present utility model.

Shown in Fig. 1-4, the utility model screw-hole type electronic experiment plate comprises a substrate 1 of being made by insulating material, and substrate 1 is the rectangular slab that is formed by integrally moulded compacting in the present embodiment.Offer a plurality of screws 2 above this substrate 1, the upper diameter of screw is that right cylinder, bottom are the shrinkage pool (as shown in Figure 4) of cone greater than lower diameter and form a top.

These many screws 2 are fitly to be arranged on the substrate 1, and their spread pattern can be the geometric configuration of various suitable electronic circuits, and as shown in Figure 2, the screw 2 on the substrate 1 of present embodiment is to become to debug line proper alignment.This substrate with the default screw of proper alignment is convenient to produce.

These screws 2 can be offered and be through hole, promptly open above substrate to the bottom surface; Also can make and the disconnected shrinkage pool in bottom surface.Wherein, be that right cylinder, bottom are that the shrinkage pool of cone is good to be designed to upper diameter greater than the top of lower diameter, because the shape of this hole body is complementary with the screw of dispose use, is convenient to use the screw fixed electronic element, plays the effect of conduction simultaneously.

In addition, the axle center with each screw 2 on substrate 1 is the center, is provided with a cross groove 3 that is connected with the edge of this screw at each screw periphery.This radial groove structure (being regardless of shape) is convenient to the user before the pin of electronic component or lead are connected, and is pressed into earlier in the groove, and the rotation that makes it to be unlikely to screw is wound into lead on the screw.

Extend the one-body molded protruding block 5 that is provided with in substrate 1 bottom surface respectively downwards with each screw 2 corresponding position, be that protruding block 5 is made circular block in the present embodiment, and connected by reinforcement 6 between each round bump, this structure is beneficial to economical with materials, does not influence its intensity again.

Also be respectively equipped with the feet 7 a little more than projection 5 on four jiaos on the periphery of substrate 1 bottom surface, screw drills through substrate and causes desktop to damage when preventing to operate.

When carrying out education experiment, need to be equipped with a plurality of self-tapping screws 8 that match with screw 2, the student need only directly directly fix screw and pin that is connected electronic component or lead (as shown in Figure 1) on screw plate with screwdriver according to electrical schematic diagram.Because screw 2 is tapered holes, and ring is established a stage portion 21 in it, and its shape and self-tapping screw be coupling.Put in the screw 2 when self-tapping screw 8, screwed to stage portion 21 earlier, and then firmly its pressure is screwed to the solid position, bottom of substrate 1, and further tightened fixing.So, press circuit diagram, one by one the pin or the lead of electronic component are fixed on the substrate 1 with screw.Detecting instruments such as just available multimeter, oscillograph measured signal at an easy rate after connection finished, but student's Direct observation relevant data or vivid, easier raising student's learning initiative.

Plate base 1 big small size of the present utility model is regardless of, and can be made into less plate, several substrate in combination can be got up connect into than large tracts of land during use, and applicable to some complicated electronic circuits.

The utlity model has following advantage:

1. simple to operate, make the student in limited instructional blocks of time, can obtain the chance that more uses one's hands and brains, make Association's construction in line with the drawings how, and then progressively allow the student learn according to the difference that electrical schematic diagram and side circuit are arranged Oneself designs Pareto diagram, and the pluses and minuses of more different Pareto diagrams make the student that sufficient space of thinking can be arranged, and more Be conducive to cultivate student's the ability of practice and creativity.

2. the utility model is different from existing children's electronic toy " electronics magic square ", and it all directly uses each Plant electronic component, be not attached to other support or shell on the element, the student can directly see, touch this A little elements, thereby have intuitive, to be convenient to test and to carry out observation experiment, the instructor is to student's works Also can be very clear, and break down and be easy to make a comment or criticism, be easy to get rid of.

3. for the user, needn't prepare a whole set of complexity such as power supply, Iron Stand, welding rod, solder flux Instrument and material need only dispose according to electronic circuit the self-tapping screw of some, and a screw plate can Repeated multiple times use, thus required cost low, draw materials easily, simple to operate, flexibility is strong, and safety, Be easy to popularize and promote.
