Background technology
Analog circuit is a required specialized core course of electric Major, very heavy in whole course offered
Will.In present analogous circuit experiment class, typically there are two methods to take circuit debugging：One kind is to use finished product experimental box, another
Kind it is voluntarily welding circuit.The former is fixed using element, and student connects circuit and the form debugged using wire；The latter is certainly
Row design circuit board is simultaneously processed to circuit board, and student also needs to be debugged after component is welded on circuit board.Before
Person's convenient disassembly, a variety of circuits can be voluntarily connected, but, experimental box fairly simple inadequate to student ability exercise there is also process
It is bulky, repair the shortcomings of inconvenient；The latter is capable of the manipulative ability of more preferable exercise student ', but designs and make circuit
Plate excessive cycle, also higher is required to the knowwhy of student, student often directly abandons because difficulty is too high, is not suitable for
In the teaching of higher vocational college school；And the circuit board that the latter uses can not carry out component weldering according to different circuit diagrams
Connect, it is impossible to Reusability.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind for above-mentioned the deficiencies in the prior art to be used to impart knowledge to students
Circuit experiment board, this be used for impart knowledge to students circuit experiment board facilitate student carry out experimental implementation, saved make pcb board when
Between；Small in volume, it is easy to granting and recovery of the teacher to student；And dismounting component is convenient, repeated multiple times can use.
To realize above-mentioned technical purpose, the technical scheme that the utility model is taken is：
A kind of circuit experiment board for being used to impart knowledge to students, including brassboard body, if the surface of the brassboard body is provided with
The dry pin bores in matrix arrangement, metal rivet each is installed in the pin bores and is used for welding component.
It is the downward 2cm in upper edge of the brassboard body, following as the further improved technical scheme of the utility model
Along upward 1cm, left margin, 1cm and the right are provided with the pin that several are in matrix arrangement along in the range of 1cm to the left to the right
Hole.
As the further improved technical scheme of the utility model, the lateral separation between each pin bores is
1.5cm and vertical distance is 1.5cm；A diameter of 3.5mm of the pin bores.
As the further improved technical scheme of the utility model, the surface of the brassboard body is additionally provided with several
Screw hole, the screw hole are used to install the component for needing to use screw to install.
As the further improved technical scheme of the utility model, each screw hole is upper with the brassboard body
The distance between edge is that the diameter of 1cm and screw hole is 5mm.
As the further improved technical scheme of the utility model, it is separately installed with four angles of the brassboard body
Feet hole, the feet hole are used to install feet.
As the further improved technical scheme of the utility model, a diameter of 3.5mm in the feet hole.
As the further improved technical scheme of the utility model, the pin bores are 96, and the screw hole is 5.
As the further improved technical scheme of the utility model, the size of the brassboard body is 20cm*15cm, institute
It is epoxy resin material to state brassboard body.
The utility model dismounting component is convenient, component can be welded according to circuit diagram, reusing wire need to
The pin for the component to be connected connects, therefore can make different experiments according to different circuit diagram Reusabilities, warp
Ji property is good, can save substantial contribution；And facilitate student to carry out experimental implementation, save the time for making pcb board；Small volume
It is in light weight, it is easy to granting and recovery of the teacher to student；Welding in need component and wire can be welded on brassboard
The side of body, it is clear in structure very clear, it is easy to evaluation of teacher, is also convenient for repairing when breaking down.
