Description

Exempt from patch Experiment of Electrical Circuits instrument

Technical field

The utility model relates to a kind of electronic circuit experiment device.

Background technology

In Experiment of Electrical Circuits, in the past to the three kinds of modes of having built of experimental circuit: a kind of is to weld on printed circuit board (PCB), and this method shortcoming is the disposable uses of components and parts, needs welding circuit again when changing scheme, and labour intensity is big, the experimental cost height; Another kind method is to build on bread board, connects each pin of components and parts by plug wire, and the shortcoming of this kind method is that a large amount of uses of patch make it very not attractive in appearance, a large amount of interference have also been introduced, circuit confusion after line is finished causes loose contact easily and is difficult to failure judgement, debug difficulties; Also having a kind of method is software emulation, can be directly finish the building of circuit, test job with software on computers, but shortcoming is also understood easily, the one, component library is complete inadequately, the 2nd, software emulation be the ideal state of components and parts, also have gap with the actual performance of components and parts, be difficult to describe the actual working state of circuit.

Summary of the invention

The utility model provides a kind of patch Experiment of Electrical Circuits instrument of exempting from, and the labour intensity exist in the experimental circuit build process is big, experimental cost is high to solve, debug difficulties, be difficult to describe the problem of the actual working state of circuit.The technical scheme that the utility model is taked is:

Comprise switch arrays, socket, X test port and Y test port on the wiring board, wherein the switch arrays district forms m * n switch arrays by m * n switch, m, n is integer, and place up and down in the circuit board two contacts of each switch, and the lower contact of every capable switch connects together and forms delegation, be contact row, the upper contact of every row switch connects together, and forms row, is rows of contacts; In the circuit board, m contact row links to each other with x end and corresponding each pin of X test port of socket respectively, and n rows of contacts links to each other with y end and corresponding each pin of Y test port of socket respectively.

In the utility model, socket adopts Zero plug-in force socket.

In the utility model, be provided with low-tension supply in the circuit board.

Originally exempt from the plug wire test instrument when building circuit using, only to need be placed on components and parts in the socket, toggle switch array respective switch can realize the connection and the disconnection of each components and parts respective pins as required, thereby finishes the building of circuit.When changing circuit arrangement, only need to change components and parts, the break-make that changes respective switch gets final product; At x, the y test port can conveniently be realized the test to circuit.

The utility model advantage is novel structure, can be used as the substitute products of bread board commonly used in the Experiment of Electrical Circuits.Use the utility model both can overcome and build hookup wiring difficulty, wiring is random, and working strength is big, the problem of loose contact again can be simple to operate, and is with low cost, lossless to components and parts, the electronician is placed on more energy in circuit design and the debugging.Can improve experimenter's work efficiency greatly, reduce cost.

Embodiment

Comprise switch arrays 4, socket 2, X test port 1 and Y test port 3 on the wiring board, wherein the switch arrays district forms m * n switch arrays by m * n switch, m, n is integer, and place up and down in the circuit board two contacts of each switch, and the lower contact 6 of every capable switch connects together and forms delegation, be contact row, the upper contact 5 of every row switch connects together, and forms row, is rows of contacts; In the circuit board, m contact row links to each other with x end and corresponding each pin of X test port of socket respectively, and n rows of contacts links to each other with y end and corresponding each pin of Y test port of socket respectively.Socket adopts Zero plug-in force socket.

In the utility model, be provided with low-tension supply 7 in the circuit board.

Application Example 1: charging circuit

Three components and parts of this circuit are formed, and are respectively power supply, resistance and electric capacity.

Step 1: components and parts are carried out label.Because these three components and parts all are the two ends elements, in circuit diagram, its port label is respectively x1, y1; X2, y2; X3, y3 (as shown in Figure 5).

Step 2: behind the port label, ensuing work is plugged on three kinds of elements on the Zero plug-in force socket by its label exactly.

Step 3: closed then matrix switch x1y2, x2y3, x3y1.

So far, then the hookup overlap joint finishes, and can carry out experiment work.When changing corded arrangement, only need to be plugged on the socket again with components and parts label in the circuit diagram, the on off state of changing corresponding matrix switch gets final product.

Application Example 2:555 square wave generation circuit,

555 square wave generation circuit, mainly by 555 chips, resistance, electric capacity, power supply, pilot lamp is formed, and on the utility model it is carried out building of circuit set by step below.

Step 1: the components and parts port is carried out label.As shown in Figure 6,555 chips, 1,2,3,4 pins are denoted as x1, x2, x3, x4.5,6,7,8 pins are denoted as y1, y2, y3, y4.The R1 two ends are respectively x9, y9.The R2 two ends are respectively x8, y8.The C1 two ends are respectively x7, y7.The C2 two ends are respectively x6, y6.Pilot lamp L two-port is respectively x5, y5.The both ends of power mouth is respectively x20, y20.

Step 2: press label each components and parts are inserted Zero plug-in force socket.

Step 3: according to the closed corresponding toggle switch of label on the circuit diagram, as the x5 that has that links to each other with x1, x7, y6, four ports of y20, closed toggle switch x1y6, x1y20, x5y6, x7y6 can finish the connection of each port on this circuit.All the other each bar line connections similarly.

Step 4: can carry out the debugging of circuit, test job after overlap joint is finished.At x, the y test port can conveniently be realized the test to circuit.
