Abstract
The utility model discloses an electronic experiment material for middle school students and pupils, which is only used for the experiment material for middle school students and pupils and , relates to an experiment material for middle school students and pupils which and brings conveniences to the student experiment. The electronic experiment materialutility model mainly consists of a bread board and an electronic element; the pin of the electronic element is inserted into the jack of the bread board and then the electronic element is fixed on the bread board; the pin of the electronic element is contacted and electrically connected with the metal reeds in the jack of the bread board; as the metal reeds inside the jacks of the same row are mutually communicated each other, the electric connection between each electronic element can be realized; the pin of the electronic element is pulled out from the jack of the bread board and then the electronic element is separated with from the bread board. The electronic experiment material for middle school students and pupils is easy to obtain the materials, is low in cost and can repeatedly used.
Description
Technical field:
The utility model relates to the inside and outside experiment in primary and secondary students classroom, only as primary and secondary students' experiment material, and especially a kind of students in middle and primary schools' electronic experiment cover material.
Background technology:
At present, along with in, the implementing in full of primary school course of study reform, the material of the natural sciences experiment that school is original is difficult to adapt to the requirement of fresh course, does not still have a cover to carry light, with low cost, easy to operate, as to be suitable for primary and secondary students' classroom experiment and extracurricular activities electronic experiment cover material.
Summary of the invention:
The purpose of this utility model provides a kind of students in middle and primary schools' electronic experiment cover material, and it is not only drawn materials easily, and with low cost, can also reuse.
Technical scheme: a kind of students in middle and primary schools' electronic experiment cover material, only as primary and secondary students' experiment material, forming main material of the present utility model is bread board and electronic component, the jack of the pin inserting surface wrapper sheet of electronic component, electronic component just is fixed on the bread board, contact electrical connection between the metal spring leaf in the pin of electronic component and the bread board jack,, just can realize electrical connection separately between the electronic component because of the metal spring leaf of the same row jack of bread board inside is interconnected; The pin of electronic component is extracted from the jack of bread board, and electronic component just separates with bread board.
For having only tie point not have the electronic component of pin,, can on tie point, if connecting, the insertion of electronic component pin meet drawing principle or related request as pin by welding lead, just experiment can be successful as toy trumpet, Electret condenser microphone, miniature bulb etc.; When the student does not do experiment (the utility model idle state), put into school bag behind the finishing and packing free-hand can the separation electronic component with bread, so that next time, experiment was used again.
Beneficial effect: the novel electronic component easy, cheap, that remove from welding, the experiment cover material of drawing materials of this use can be reused.
Description of drawings:
Below in conjunction with drawings and Examples, to new novel being described further of this practicality.
An experiment when Fig. 1 is the utility model functional status connects sample.Corresponding teaching material is primary school's science senior class " science " volume two P8 (religion section version) " allow more miniature bulb light " class, in the drawings: 1. bread board, 2. jack, 3. battery, 4. battery case, 5. miniature bulb 6. connects lead.
Embodiment:
Because students in middle and primary schools grade difference, course offered is also different, therefore the utility model in the specific implementation, be according in, the requirement of primary school course of study (comprising courses such as science, physics, labor skill, practical activity), determine the size of kind, quantity and the bread board of electronic component in the cover material, just form the electronic experiment cover material of several groups, or roughly the utility model has been defined as primary school, junior middle school, three groups of senior middle school.The electronic component of each group electronic experiment cover material the inside can be different, even the electronic experiment of same grade cover material also can have different preparations.
What experiment shown in Figure 1 related to material is primary school's senior class electronic experiment cover material, the preparation menu of this experiment cover material is as follows: 1 of the bread board of small size, 2.5V 2 of miniature bulbs, 1 on the switch of pin in the welding, each 1 of 3V redness and green LED, each 1 of 100 Ω, 1K Ω resistance, 1 of the battery case of 3V5 battery, 10 in the single core plastic skin of 5 centimeter length lead, obviously the part experiment material in the cover material has only been selected in this experiment for use.
In Fig. 1, each miniature bulb in the miniature bulb (5) respectively is welded with two conductions as pin, the jack (2) that each root pin difference inserting surface wrapper sheet (1) is laid above, each pin is not at same row jack, an end that connects lead (6) inserts the jack of a pin column of a miniature bulb, the other end that connects lead (6) inserts the jack of a pin column of another miniature bulb, battery case (4) two pins inserts the row at all the other two pin places of miniature bulb respectively, the battery (3) of in battery case (4), packing into, because of bread board (1) provides the circuit connection, miniature bulb (5) is lighted.
Claims (2)
1. students in middle and primary schools' electronic experiment overlaps material, only as primary and secondary students' experiment material, it is characterized in that: described electronic experiment cover material is made up of bread board and electronic component, insert between the pin of electronic component and the jack of bread board and be connected, metal spring leaf in the pin of electronic component and the bread board jack contacts electrical connection, the pin of electronic component is extracted from the jack of bread board, realize electronic component just with the separating of bread board.
2. a kind of students in middle and primary schools' electronic experiment cover material according to claim 1 is characterized in that: described electronic experiment cover material has packaging shell.
