Description

Electronic circuit experiment plate

Technical field

The utility model relates to a kind of electronic circuit experiment device, especially relates to the improvement of electronic circuit experiment plate.

Background technology

At present, there are a lot of weak points in popular several electronic circuit experiment devices, are illustrated respectively below:

One, electronic circuit experiment platform

There is following shortcoming in the electronic circuit experiment platform that uses in the school laboratory:

(1) the inserting mode wiring of employing Elastic Contact, the intersection point of four lines in the circuit, on experiment table, replace with four plugs and jack, with some a current potential can only be arranged by requirement of experiment, frequent during actual experiment because of four pairs of plug-sockets existence loose contact phenomenon in various degree, several different current potentials occur, cause the failure of an experiment.

(2) maximization mesa structure design has not only increased experimental cost, and unfavorable to imparting knowledge to students, and can only be unit with the group during experiment, and it is few that the student starts chance, and experimentation and result's personalized intention is not easy performance and embodies.

(3) can not do complicated experiment for the wiring point that connects very little.

(4) with plug special and line, the cost height, length can not be adjusted, and causes wiring disorderly, and the circuit intuitive is poor.

Two, bread board

Bread board is from external introduction, though patch fireballing advantage, but same tie point outside surface is five jack bar shaped arranged distribution, and inner reality has only been installed a spring leaf, the disorder of not only connecting up during experiment, intuitive is poor, owing to still adopt the wiring of Elastic Contact method, insert the end of a thread that several curved straight thicknesses differ simultaneously at a spring leaf mouth, the phenomenon of multiple spot loose contact simultaneously often appears, even fault also is difficult to search, cause experiment to go on.In a word, the electronic circuit experiment device of the inserting mode wiring of all employing Elastic Contact all exists the contact of contact poor, the ability of contact vibration proof, and the problem of the poor durability of contact.

Three, circuitron brassboard

Main popular in electrophile and electronics R﹠D institution, adopt the welding process wiring, inconvenience, beginner and students in middle and primary schools use difficulty, and conventional efficient is low, and wiring is disorderly, occurs rosin joint and short trouble easily, and serviceable life is short.

Four, special-purpose experiment external member

The special-purpose assorted experimental facilities of being had made to order by factory according to syllabus and textbook content is used in the laboratory of some professional universities and colleges and vocational school.Because the speed that the speed that development of electronic technology speed and electronic component update and talent's vocational need kind of bringing along with market economic development change is all very fast, and the disadvantage of special-purpose experiment external member is that versatility is poor, the experiment investment is big, in case offer the change of specialty and textbook content the experiment external member is eliminated, the serviceable life of therefore general special-purpose experiment external member is all very short, can bring the excessive risk of investment.
